Detailed ways

In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

The technical solutions disclosed in various embodiments of the present application will be described in detail below with reference to the accompanying drawings.

In the related art, the housing of the endoscope handle is formed by the docking of two sub-shells, and multiple sets of positioning structures need to be provided on the butt joint surfaces of the two sub-shells, such as positioning slots and positioning blocks. Only when all are aligned, the positioning block and the positioning groove can be smoothly snapped into each other, thereby realizing the assembly of the two sub-shells. The inventor found that during the process of assembling the housing of the endoscope handle of the above-mentioned related art, it is inconvenient for the operator to observe the positioning groove and the positioning block, which makes it difficult for some positioning blocks to be aligned and loaded into the positioning groove, and the operator It is necessary to repeatedly adjust the relative positions of the two sub-shells, and try to align them completely before they can be assembled. It can be seen that the layout of the handle housing of the traditional endoscope seriously affects the assembly efficiency.

In addition, the inventors also found that the traditional endoscope handle housing needs to go through multiple trial assembly operations, and the positioning structures (such as positioning grooves and positioning blocks) on the sub-housing are often due to multiple touches, repeated over-crowding, etc. Damaged due to pressure, resulting in poor positioning between the sub-shells.

In this regard, some embodiments of the present application provide a handle housing for endoscopes, by providing a gap on the sub-shell that communicates with the positioning recessed structure, a certain accommodation space is provided through the gap, and the sub-shell can also be used The rigidity of the part of the shell around the positioning concave structure is reduced, so as to adapt to the snap-in action of the positioning protrusion structure on the other sub-shell through elastic deformation, so as to realize the rapid alignment assembly of the shell.

Referring to FIGS. 1-9 , the handle housing 100 disclosed in the embodiment of the present application includes a first sub-housing 110 and a second sub-housing 120 that can be docked and assembled, wherein: the docking surface S1 of the first sub-housing 110 is provided with a first The positioning part 111, the butt surface S2 of the second sub-shell 120 is provided with a first recess 121 that is positioned and matched with the first positioning part 111, and the first sub-shell 110 and the second sub-shell 120 are connected to the first recess by the first positioning part 111 121 to achieve alignment; the mating surface S2 of the second sub-housing 120 is also provided with a notch 122 communicating with the first recess 121 to form a movable space capable of accommodating part of the first positioning portion 121 .

It can be understood that the handle housing 100 is a basic component of the endoscope handle, which can be used as a bearing base for other components of the endoscope handle, and can protect other components. The first sub-housing 110 and the second sub-housing 120 are two parts of the handle housing 100 , and can be assembled by clamping, bonding, screwing and other ways.

In the embodiment of the present application, the first positioning part 111 and the first concave part 121 constitute the positioning structure of the handle housing 100, and the first positioning part 111 can be snapped into the first recess 121 to realize the positioning fit of the corresponding parts of the two sub-housings. Certainly, the combination of the first positioning portion 111 and the first concave portion 121 may have multiple groups, so as to realize positioning fit at different positions of the butting surfaces of the two sub-housings, and form multiple positioning positions at different positions of the butting surfaces of the two sub-housings. point to achieve a more stable and reliable positioning effect.

Wherein, the embodiment of the present application does not limit the specific structure of the first positioning part 111 and the first concave part 121, as shown in Figure 2 and Figure 3, the first positioning part 111 can be a bump, and the first concave part 121 can be a groove . Further, in order to adapt to the narrow layout environment on the mating surface of the sub-housing, the first positioning portion 111 may be a bar-shaped piece, and the first concave portion 121 may be a bar-shaped groove.

Regarding the notch 122 provided on the abutting surface S2 of the second sub-case 120, since it communicates with the first recess 121, the existence of the notch 122 will reduce the structural rigidity of the second sub-case 120 around the first recess 121, thereby The surrounding structure around the first concave portion 121 can be more easily elastically deformed. When the first sub-shell 110 and the second sub-shell 120 are butted and assembled, the first positioning portion 111 and the first concave portion 121 will be pressed against each other, while the first The concave portion 121 and its surrounding structures can adaptively avoid the first positioning portion 111 through elastic deformation, so that it is easier to realize the mutual engaging action of the first positioning portion 111 and the first concave portion 121 .

It should be understood that even when the first sub-case 110 and the second sub-case 120 are docked, part of the first positioning portion 111 and the first recess 121 are not aligned, but when the structure surrounding the first recess 121 is elastically deformed and aligned with During the process of the first positioning parts 111 snapping into each other, the relative positions of the first sub-case 110 and the second sub-case 120 are actually in a state of self-adaptive adjustment. When most of the first positioning part 111 and the first concave part 121 After they are aligned and snapped in, the first sub-housing 110 and the second sub-housing 120 are already in a state of complete alignment, so that quick alignment and assembly can be achieved. It can be seen that during the docking and assembling process of the handle housing 100 of the embodiment of the present application, there is no need to deliberately adjust the relative positions of the first sub-housing 110 and the second sub-housing 120 for alignment, and the two can pass through the first positioning part 111 and the first The self-adaptive snap-in action of the concave portion 121 realizes self-adaptive alignment.

At the same time, the notch 122 can also provide accommodating space for the first positioning part 111, which is equivalent to providing a redundant activity space for the first positioning part 111. When the first sub-shell 110 and the second sub-shell 120 are docked and assembled, the second A positioning part 111 can partially extend into the notch 122, and then move into the first recess 121, which can reduce the interference and obstruction of the first positioning part 111 in the process of snapping into the first recess 121, and reduce the first positioning. It is difficult for the part 111 to snap into the first concave part 121, so that quick alignment and assembly can be realized.

In the case that the notch 122 can provide a larger movable space for the installation of the first positioning part 111, the difficulty of the first positioning part 111 and the first concave part 121 being locked into each other is significantly reduced, which reduces the need for the first positioning part. 111 and the size specifications of the first concave portion 121, so that the processing accuracy requirements of the two can be reduced, and the further effect of saving processing costs can be achieved.

Compared with related technologies, the handle housing 100 disclosed in the embodiment of the present application overcomes the problem that the sub-housings cannot be quickly aligned and assembled by setting the gap 122 communicating with the first recess 121, thereby effectively improving the endoscope handle housing. Assembly efficiency of the body 100. At the same time, it is precisely because the handle housing 100 of the embodiment of the present application can realize quick alignment and assembly between the sub-housings, thus avoiding multiple touches and repeated excessive extrusion between the first sub-housing 110 and the second sub-housing 120. damage, thereby ensuring a better positioning effect between the sub-shells.

As shown in FIG. 9 , in some embodiments of the present application, along the thickness direction of the side wall of the second sub-case 120, the end of the notch 122 away from the first recess 121 is a closed structure, that is, the notch 122 does not pass through Surrounding the sidewall of the first recess 121 . In this embodiment, the notch 122 can be disposed on one side of the side wall of the second sub-case 120 in the thickness direction. Of course, the notch 122 can also be disposed on one side of the first concave portion 121 in the extending direction.

As shown in FIGS. 4 to 8 , in another embodiment, the notch 122 penetrates along the thickness direction of the side wall of the second sub-case 120 .

It can be understood that the notches 122 in this arrangement make the first concave portion 121 an open concave structure, which can further reduce the rigidity of the structure around the first concave portion 121 of the second sub-case 120 and make this part of the structure easier to The elastic deformation is realized, so that the first positioning part 111 and the first recessed part 121 are more convenient to be snapped in quickly during the docking and assembling process of the first sub-case 110 and the second sub-case 120 .

Optionally, in the embodiment where the notch 122 penetrates through the thickness direction of the side wall of the second sub-case 120, the bottom surface of the corresponding notch 122 on the second sub-case 120 is deeper than the bottom surface of the first recess 121, thus further strengthening the notch 122 reduces the performance of rigidity; or, the bottom surface of the corresponding notch 122 on the second sub-shell 120 is coplanar with the bottom surface of the first recess 121, so that the first positioning part 111 can slide into the first recess 121 through the notch; or, the second The bottom surface of the corresponding notch 122 on the sub-case 120 is higher than the bottom surface of the first recess 121 , and this part of the structure can realize the limit of the first positioning part 111 in the corresponding area of the notch 122 to optimize the first positioning part 111 The positioning effect of snapping into the first concave portion 121 .

In addition, at least part of the opening of the first recess 121 and the surface of the second sub-case 120 corresponding to the notch 122 can be provided with a guide surface, so as to facilitate the first positioning part 111 to snap into the first recess 121, or to facilitate the first positioning part 111 Enter the notch 122 and then move into the first recess 121 .

As shown in FIG. 5 , in some embodiments of the present application, the second sub-case 120 is provided with a snap-fit part 127 for snap-fitting with the first sub-case 110 , and the snap-fit part 127 is in contact with the first concave part 121 Adjacent arrangement. Such a layout can reduce the rigidity of the corresponding area of the engaging part 127 through the first concave part 121 and the notch 122, and the engaging part 127 needs to be elastically deformed in the process of realizing the engaging fit, which is obviously beneficial for the engaging part 127 to realize the engaging fit .

Further, as shown in FIG. 5 , the engaging portion 127 is located on the side of the first concave portion 121 close to the notch 122 , so that the stiffness of the area where the engaging portion 127 is located can be further reduced, and the engaging portion 127 can be further optimized to achieve engaging Cooperation efficiency. As shown in FIGS. 4 to 8 , in some embodiments of the present application, the notch 122 runs through the first side wall 121 a of the first recess 121 , and the first side wall 121 a is the inner cavity of the first recess 121 close to the second sub-shell 120 side wall.

It can be understood that the embodiment of the present application does not limit the opening orientation of the notch 122 , which may be towards the outside of the second sub-case 120 . In addition, the side wall of the first recess 121 actually belongs to a part of the side wall of the second sub-case 120, and the first side wall 121a of the first recess 121 is the structure surrounding the first recess 121 on the second sub-case 120. part of the inner cavity of the second sub-shell 120 . Under the above structural layout, the notch 122 passes through the first side wall 121a of the first recess 121, and its opening faces the inner cavity of the second sub-housing 120. When the rigidity of the structure around the first recess 121 is reduced by the notch 122, It can also ensure the sealing performance of the outer surface of the second sub-housing 120 to prevent foreign matter from entering the handle housing 100, thereby improving the protection level of the endoscope handle.

As shown in FIG. 4 , in some embodiments of the present application, the first length L1 of the notch 122 along the extending direction of the first concave portion 121 is equal to the second length L2 of the first concave portion 121 along its extending direction. The rigidity of the structure surrounding the first recess 121 on the second sub-case 120 is greatly reduced, and the notch 122 can also allow the first positioning part 111 to pass through laterally, which can significantly improve the relationship between the first positioning part 111 and the first recess 121. Card-in efficiency.

As shown in FIGS. 5-8 , in another embodiment of the present application, the first length L1 of the notch 122 along the extending direction of the first concave portion 121 is smaller than the second length L2 of the first concave portion 121 along its extending direction. It can be understood that under such a layout, the notch 122 with the first length L1 can reduce the rigidity of the structure around the first recess 121, and the notch 122 does not completely occupy the layout of the side wall of the first recess 121 on the side of the notch 122. space, and the sidewalls of these first recesses 121 on the side of the notch 122 can limit the first positioning part 111, thereby ensuring that the first positioning part 111 and the first recess 121 still have a better position after they are locked into each other. positioning effect.

Further, as shown in FIGS. 5 to 8 , in some embodiments of the present application, one end of the notch 122 coincides with one end of the first recess 121 correspondingly. It can be understood that, with such a layout, the notch 122 is set close to one end of the first recess 121, so that when the first positioning part 111 snaps into the first recess 121, even if the first positioning part 111 and the first recess 121 exist With a certain inclination, the first positioning portion 111 can also extend into the first concave portion 121 , so as to realize quick alignment and assembly of the first sub-case 110 and the second sub-case 120 .

And/or, the number of notches 122 is multiple, and the plurality of notches 122 are arranged at intervals along the extending direction of the first recess 121 . It can be understood that, in the case where a plurality of notches 122 are provided corresponding to one first recess 121, the plurality of notches 122 are arranged along the extension direction of the first recess 121, so that the effect of the notches 122 on reducing the structural rigidity can be extended in the extension of the first recess 121. In this way, the notch 122 can expand the scope of reducing structural rigidity, so that the structure surrounding the first concave part 121 on the second sub-shell 120 is more convenient to achieve elastic deformation, thereby further optimizing the first sub-shell 110 and the second sub-shell. The shell 120 is capable of quick alignment assembly.

It should be noted that, in the embodiment where one first concave portion 121 corresponds to multiple notches 122 , the multiple notches 122 may be distributed on multiple sides of the first concave portion 121 .

As shown in FIGS. 6 and 7 , in some embodiments of the present application, a first reinforcing portion 123 is provided on the inner surface of the second sub-shell 120 , and the first reinforcing portion 123 is connected to the corresponding side wall of the second sub-shell 120 . The location of the first recess 121 . It can be understood that since the first recess 121 and the notch 122 are provided on the abutting surface S2 of the second sub-case 120, the first recess 121 and the notch 122 will reduce the overall strength of the second sub-case 120, and the structure based on this embodiment Layout, the first reinforcement part 123 can correspondingly increase the strength of the part of the second sub-shell 120 corresponding to the first concave part 121, which can avoid the existence of weak areas on the second sub-shell 120, thereby ensuring that the handle housing 100 as a whole has a better strength and protection performance.

And/or, as shown in FIG. 2 , FIG. 3 and FIG. 8 , in some embodiments of the present application, the second sub-housing 120 includes two first recesses 121 disposed on one side of the distal interface 101 and arranged opposite to each other. , the notch 122 is disposed at an end of the first concave portion 121 away from the interface 101 .

It can be understood that since the interface 101 is jointly formed by the docking of the first sub-shell 110 and the second sub-shell 120, it has higher requirements on the alignment effect of the first sub-shell 110 and the second sub-shell 120 at their distal ends, Otherwise, the normal use of the interface 101 will be affected. In this embodiment, the second sub-housing 120 is provided with two first recesses 121 on the side of the distal interface 101, and correspondingly, the first sub-housing 110 is also provided with two recesses 121 on the side of the distal interface 101. The first positioning part 111 optimizes the positioning effect of the first sub-shell 110 and the second sub-shell 120 on the side of the distal interface 101 of the two through two sets of positioning structures, so as to ensure that the two sub-shells can be better positioned on this side. Realize alignment assembly while ensuring to form the interface 101 of standard size.

Further, as shown in FIG. 6 and FIG. 7 , in some embodiments of the present application, the inner surface of the second sub-shell 120 is also provided with a second positioning portion 124 for positioning and matching with the first sub-shell 110 , the second The positioning portion 124 is arranged adjacent to the first concave portion 121 , and an end of the first reinforcing portion 123 away from the first concave portion 121 is connected to the second positioning portion 124 .

It can be understood that the second positioning portion 124 can further optimize the positioning effect of the first sub-shell 110 and the second sub-shell 120 when they are docked and assembled. Correspondingly, the inner surface of the first sub-shell 110 is provided with a The third positioning portion 112 , the second positioning portion 124 , and the third positioning portion 112 that are positioned together form another positioning structure besides the combination of the first positioning portion 111 and the first concave portion 121 .

A recess 121 is adjacent to a side wall of the inner chamber of the second sub-housing 120 . It can be understood that based on the existence of the first recess 121 and the notch 122, the strength of the corresponding part of the second sub-shell 120 will be reduced. The side walls corresponding to the first recess 121 and the notch 122 in 120 are easily damaged due to extrusion, but based on the above-mentioned structural layout, since the first reinforcement part 123 is connected to the first side wall 121a of the first recess 121, this can effectively The strength of the part surrounding the first concave portion 121 and the notch 122 in the second sub-case 120 is improved, so that the problem that the structure of this part is easily damaged can be overcome, and the service life of the second sub-case 120 can be prolonged.

Of course, the solution of connecting the first reinforcing part 123 to the first side wall 121 a of the first concave part 121 can be used in the solution of connecting the first reinforcing part 123 to the second positioning part 124 .
