In order to facilitate understanding of the present invention, the present invention will be described more fully below with reference to the following embodiments and effect drawings. The preferred embodiments of the present invention have been described. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly secured to the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1, the closed-state seam guard 10 of an embodiment includes a sensing switch 100, goggles 110, a connecting seat 120, and a mounting holder 130. Fig. 2 shows the seam protector 20 in a non-closed state according to the embodiment of fig. 1, and it will be clear and accurate to recognize the technical solution of the present invention in combination with fig. 1 and 2, and at the same time, the utility model is also clear at a glance.

The goggles 110 are directly connected to one side of the connecting base 120, and the other side of the connecting base 120 is connected to the bottom end of the fixing base 130.

As a specific example, the protective glasses 110 may be a transparent adhesive plate, but may also be selected from other materials, such as glass, metal plate, etc., and the present invention is not limited thereto.

More specifically, a practical shape of the protective glasses 110 is shown in fig. 1 and 2, which are two mutually perpendicular transparent adhesive plates connected in an arc shape, i.e. 111 plane and 112 plane, respectively, so that the protective glasses can prevent the broken needle from splashing to two directions where the transparent adhesive plates are located, and protect the position where the operator is located. One of the transparent rubber plates is far away from the connecting seat, and the other transparent rubber plate is connected with the connecting seat, so that the protective glasses 110 can be switched between a closed state and an open state along with the connecting seat. The goggles 110 may also include a viewing aperture, shown at 113, to facilitate real-time observation of the needle position during sewing by the sewing machine during actual operation by an operator. The specific shape of the goggles 110 described above may be more clearly understood with reference to the embodiment of the seam guard in the closed position of FIG. 1 and the embodiment of the seam guard in the non-closed position of FIG. 2.

The goggles 110 are coupled to the coupling sockets 120 in a manner of being fixedly coupled through the first coupling holes 114 as shown in fig. 1. Of course, it will be readily appreciated that the connection may be made in other ways. For example, the protective glasses 110 and the connecting seat 120 are glued together by using glue, or the two components are directly formed integrally when being specifically prepared, or the two components are connected by a clamping groove or a sliding rail, so long as the purpose of connecting the protective glasses 110 and the connecting seat 120 together can be achieved.

In this embodiment, the connecting base 120 is a rotary connecting base, which includes a first rotating shaft 121, a rotating plate 122, a second connecting hole 123 and a magnet 124. Referring to the view shown in fig. 1, the lower side of the connecting socket 120 is connected to the upper side of the goggles 110 through the first and second connecting

holes

114 and 123, and the rotating plate 122 is parallel to the surface 111 of the transparent rubber plate of the goggles 110.

The mounting fixture 130 includes a second rotation shaft 131, a bottom plate 132, an iron block 133, and a third connection hole 134.

The bottom plate 132 of the mounting holder 130 can be connected and fixed with the sewing machine body. As a specific example, the bottom plate 132 is shown in fig. 1 and includes two perpendicular plate surfaces, and two mounting holes are respectively formed on the two plate surfaces and correspond to the shape of the sewing machine body for fixing the sewing machine body.

In the above-mentioned sewing guard, the upper side of the connecting seat 120 is connected to the lower side of the mounting fixing seat 130 through the first rotating shaft 121 and the second rotating shaft 131, and the rotating shafts are parallel to the horizontal plane. Thus, the connecting base 120 can drive the goggles 110 to rotate up and down around the rotating shaft to the operator to switch between the closed state and the non-closed state.

The inductive switch 100 is fixed at a lower corner of the mounting holder 130 and is adjacent to the rotation axis between the connecting seat 120 and the mounting holder 130, and can block the rotation of the rotating plate 122.

The operation of the above-described embodiment will be further described with reference to the seam guard shield shown in fig. 1 with the shield in a closed position and the seam guard shown in fig. 2 with the shield in an open position. The operation mode of this embodiment may be only valid for the connection relationship and the position of each component in this specific embodiment, and after the connection relationship, the connection mode or the relative position of each component is changed, the corresponding implementation mode should be adaptively changed to implement the present invention.

The connecting seat 120 of the seam protector provided in this embodiment has two rotation limits during the vertical rotation process.

In case of rotating the connecting socket 120 downward, referring to fig. 1, it can be seen that the rotation is stopped because the left side of the rotary plate 122 is blocked by the inductive switch 100 to reach the limit position of the downward rotation. At this time, the 111 surfaces of the rotating plate 122 and the goggles will be perpendicular to the horizontal table surface, the goggles are in a closed state capable of blocking the broken needle from splashing, and at the same time, the rotating plate 122 touches the inductive switch and is activated, and the sewing needle can start to work.

Then, the connecting seat 120 is rotated upward, and the rotating plate 122 is blocked by the surface 131 of the mounting fixing seat 130 in fig. 1 to reach the limit, referring to fig. 2. At this point, the rotating plate 122 and the 111 face of the goggles are turned 180 °, which will still be perpendicular to the horizontal. In the rotating process, the rotating plate 122 drives the goggles 110 to leave the original position, so that the goggles 110 no longer have the function of completely blocking the splashing of the broken needle, namely, the broken needle is switched to the open state, and meanwhile, the left side of the rotating plate 122 also leaves the inductive switch 100, the inductive switch is disconnected, the controller of the sewing needle electrically connected with the inductive switch does not receive an activation signal, and the work is stopped until the rotating plate 122 next touches the inductive switch and is activated.

When the connecting base 120 rotates upwards to the limit, the magnet 124 on the connecting base 120 contacts the iron block 133 on the mounting fixing base 130 and is adsorbed together, so that the connecting base 120 can be temporarily fixed on the mounting fixing base 130, and the temporary removal of the goggles for other operations in the actual use process is facilitated.

The sewing protection device provided by the embodiment has the advantages that the conception is ingenious, the state of the protective glasses is sensed by the inductive switch, whether the sewing needle can be started or not is correspondingly controlled according to the state, the protective glasses are ensured to be in a closed state when an operator operates, the situation that the operator mistakenly stretches hands to enter or the broken needle flies out is avoided, and the sewing protection device has practicability. In addition, in the embodiment, the state of the protective glasses is connected with the position of the rotary flat plate by means of the rotation of the rotary connecting seat, when the connecting seat rotates, the protective glasses are closed and the induction switch is activated synchronously, and the connecting seat is not complex in structure and is very simple and easy to implement.

The above-described embodiment provides only one possible way of implementing the present embodiment, but there are many equivalent implementations of various parts of the above-described embodiment, such as some examples given below.

In other specific examples, the induction switch can control the on-off of the power supply of the sewing machine main body, so that when the induction switch is activated by the rotary flat plate, the power supply of the sewing machine main body is switched on, and an operator can operate the sewing machine; or the inductive switch can only control the on-off of the power supply of the sewing needle part, namely the inductive switch only stops the sewing needle without influencing other parts.

In other specific examples, the positions of the magnet (magnetic component) and the iron block (material capable of being attracted by the magnetic component) in the embodiment can be interchanged, that is, the magnet is installed on the installation fixing seat, and the iron block is installed on the connecting seat; or the magnet can be arranged on one component of the sewing protection device provided by the embodiment, and the other component is made of a ferrous material, so long as the connecting seat can be temporarily fixed when the connecting seat rotates upwards to the limit.

In other specific examples, the inductive switch in the present embodiment may be a physical switch, which is pressed by the rotating plate to rotate downward to achieve activation; the light-sensitive switch can be also used for realizing activation by being shielded by a rotating flat plate; other types of switches including sensors are also possible, as long as the state of the goggles can be sensed directly or indirectly and the actuation of the sewing needle can be controlled correspondingly. Different inductive switches have different inductive principles, so that the position of the inductive switch can be adjusted adaptively.

In some other embodiments, the seam guard further includes an alarm component, and the inductive switch is electrically connected to the alarm component. When the inductive switch induces that the protective glasses are in an open state, the alarm component flickers a signal lamp and/or an alarm bell rings.

Fig. 3 and 4 show a schematic view of a sewing machine including the seam guard of the above-described embodiment, which includes a sewing machine main body 310 and a seam guard 320 fixed to the sewing machine main body. Wherein the goggles of the seam guard 320 of fig. 3 are in a closed state and the goggles of the seam guard 320 of fig. 4 are in an open state. The protective glasses protect two directions, the broken needle can be effectively prevented from flying out towards the direction of an operator, the observation hole 321 in the protective glasses 320 corresponds to the needle point position of the sewing needle 311 in the sewing machine main body 310, and the operator can observe the needle point position conveniently.

It should be understood that the above-mentioned embodiment is only one of the preferable feasible ways of the present invention, and the size, position, shape, etc. of each component are all implemented by the technical idea of the present invention, and the present invention is not limited to the above-mentioned implementation.

In other embodiments, the attachment socket may simply serve to connect the goggles and the mounting socket, which may not be of more elaborate construction like the above-described embodiments, e.g. it may only have a rotating shaft. The mounting fixing seat can only play a role in integrally fixing the sewing protection device.

In other embodiments, the switching of the state of the goggles can also be realized by sliding the goggles on the slide rail or by detachable goggles, so long as the goggles can be switched between the closed state and the open state. Meanwhile, an inductive switch is also correspondingly arranged, and the inductive switch can sense the switching of the states of the protective glasses and control the starting of the sewing needle.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
