Description

Compasses to accommodate refills

technical field

The utility model relates to a compasses, in particular to a compasses capable of accommodating pen cores.

Background technique

No matter the existing compasses use center piece, gear or other methods, their structure is mainly composed of compasses head, pins and lead pins. A compass head is formed on the upper end of the compass, and a stitch and a lead foot are respectively hinged, and the distance between the two is adjusted by pulling the stitch and the lead foot. The bottom end of the lead foot is inserted into a refill clip, which is penetrated by a bolt and fixed by a nut screw, and a refill is provided at the bottom of the refill clip, and a positioning pin protrudes from the bottom end of the pin for positioning. In addition, the top of the compass head is provided with a handle. When using, first adjust the radius of the drawn circle, then place the positioning pin at the center point, turn the handle to make the lead foot move in a circle, and use the pen core at the bottom of the pen core clip to draw the required arc. Existing compasses have the following disadvantages in use: (1) Traditional compasses, regardless of their shape, can be seen at a glance as compasses, and they must be stored in a box, which is troublesome to carry, so they are placed It is used in a fixed position and is not convenient to carry around. (2) The refills of the refill clips of traditional compasses are generally placed elsewhere. The same is true for compasses that directly hold the refill without a refill clip. Therefore, when the pen clip or refill needs to be replaced, the It must take time to browse and search, and even the embarrassment that it cannot be used because it cannot be found everywhere.

Detailed ways

Below in conjunction with embodiment the utility model is further described.

As shown in Figure 1 and Figure 2, the compasses that can hold the pen core include the compass head, the lead pin 22 and the pin 21. Positioning pins are provided; at the position corresponding to the bonding end of the pin 21 and the lead foot 22, a container 210 is provided inwardly, and the top and bottom of the container 210 are respectively provided with a clamping opening 212, which cooperates with the upper and lower clamping openings. The distance between them forms a cylindrical accommodating sleeve 3, and the accommodating sleeve 3 is placed in the accommodating groove 210. The pins 21 and the lead pins 22 are correspondingly provided with a container, and the container is respectively provided on the pin 21 and the lead pin 22 , and the top and the bottom of one of the containers are respectively provided with clamping openings 212 . The clamping opening 212 can also be set in the groove of the lead pin 22 .

As shown in FIG. 4 , a semicircular slot hole 31 is formed at the middle section of the housing sleeve 3 , and shaft holes 32 and arc-shaped sliding slots 33 are respectively provided on the upper and lower end surfaces thereof. As for the positioning head 4, a fixed column 41 is protrudingly provided at one end, and can be inserted through the clamping opening 212 respectively. The other end surface of the fixed column 41 located at the positioning head 4 is respectively provided with a central convex column 42 and a sliding convex column 43. . Therefore, when the accommodating sleeve 3 is inserted into the accommodating groove 210 of the pin 21 of the compass, the shaft hole 32 and the arc-shaped slide groove 33 provided by the top and bottom end faces can be respectively aligned with the center of the upper and lower positioning heads 4. The protruding post 42 and the sliding protruding post 43 are nested and positioned, and the accommodating sleeve 3 can be rotated to generate swing.

As shown in Figure 1 and Figure 3, a positioning head 4 is placed at the clamping mouth 212, and a central boss 42 is arranged on the end surface of the positioning head 4; A cylindrical shape, its upper and lower end surfaces are respectively provided with shaft holes 32 for the center boss 42 to be inserted and rotated, so that the accommodating sleeve 3 is inserted into the positioning head 4 and rotates through the center boss 42 and the shaft hole 32 .

The cooperation between the clamping mouth and the positioning head can also be set in this way, a positioning head is placed at the clamping mouth, a fixing column is provided at the clamping opening, and a concave hole matched with the fixing column is arranged on the corresponding end surface of the positioning head. Groove; the accommodating sleeve is matched with the distance between the upper and lower positioning heads to form a cylindrical shape, and the upper and lower end surfaces are respectively provided with shaft holes for the center convex column to be inserted and rotated, so that the accommodating sleeve is placed behind the positioning head and passes through the central convex The column rotates in the shaft hole, the sliding convex column and the arc chute.

The positioning head 4 is provided with a sliding boss 43 on the end face of a central boss; the accommodation sleeve 3 forms an arc-shaped chute 33 for the sliding boss; The column 42 rotates with the shaft hole 32 and the sliding protrusion 43 and the arc-shaped slide groove 33 .

As shown in FIG. 4 , a protrusion 333 is disposed inside the arc-shaped sliding groove 33 . The setting of the protrusion 333 is used to lock the accommodating sleeve 3, so that the accommodating sleeve 3 can only be rotated after being pushed hard.

As shown in FIG. 2 and FIG. 4 , the positioning head 4 is provided with a concave platform 44 , and the containing groove 212 is correspondingly provided with a convex platform 214 matching with the concave platform. The arrangement of the concave platform 44 and the convex platform 214 is used to fix the position limit of the positioning head 4 .

As shown in FIG. 4 , the accommodating sleeve 3 is provided with patterns along the length. The patterns are used to increase the friction between the user's fingers and the housing sleeve 3 .

As shown in Figure 3, when in use, after the housing sleeve 3 and the positioning head 4 are assembled in the pin 21 of the compass 2 or the receiving groove 210 of the lead pin 22, the housing sleeve 3 is first rotated so that the slot hole 31 is positioned outward. Components such as the pen core 5 can be placed in, and the housing sleeve 3 is formed into a closed state, then the pen core 5 can be stored and stored in the slot 31 of the housing sleeve 3, and can move together with the compass 2 at the same time, so when When the pen core 5 needs to be replaced, it can be taken out for use at once, eliminating the trouble of carrying or searching for it.

The control principle of the accommodation cover 3. As shown in FIGS. 5 and 6 , the accommodating sleeve 3 rotates in combination with the central post 42 of the positioning head 4 through the shaft hole 32 . When the accommodating sleeve 3 is rotated clockwise, the arc chute 33 cooperates with the sliding boss 43 to rotate, and can turn to the left end of the arc chute 33, which is an open state. When the accommodating sleeve 3 is turned counterclockwise, the arc-shaped chute 33 can be slid, until the sliding boss 43 abuts against the right end point of the arc-shaped chute 33, and the slot hole of the accommodating sleeve 3 is now 31 rotates and retracts into the receiving groove 210 of the pin 21 to form a closed state.

Therefore the utility model has the following advantages: (1) the utility model is designed to place the accommodating cover 3 directly in the groove provided by the stitch pin 21 or the lead pin 22, which can be opened or closed by rotation, and several pens are placed in the slot hole 31 The core or positioning pin can be carried and used together with the compasses, which is convenient for replacement and supplementation at any time. (2) The pen core 31 is directly stored in the accommodating sleeve 3 without being placed separately, so there is no situation that the pen core cannot be found everywhere during use.
