Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical equipment, in particular to a frame circuit breaker and an auxiliary switch. BACKGROUND

[0002] In the frame circuit breaker, the auxiliary switch is an important component, which is usually used to assist the main switch to complete specific functions. For example, the auxiliary switch can be used to output signals, transmit signals to the external console, facilitate the external console to realize the automatic control of the circuit according to the needs, detect the faults and abnormalities in the circuit, and perform signal transmission.

[0003] The auxiliary switch usually includes a base and a micro switch. In the prior art, after the auxiliary switch is installed in the frame circuit breaker, the micro switch is difficult to be taken out from the base, so that the micro switch cannot be quickly installed and disassembled, which will cause the micro switch to be more difficult to maintain or repair. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a frame circuit breaker and an auxiliary switch to reduce the installation and disassembly difficulty of the micro switch.

[0005] In a first aspect, the present application provides an auxiliary switch, which includes a base, a micro switch and a baffle. The base is provided with a receiving cavity, and the receiving cavity is provided with an opening. The micro switch is installed in the receiving cavity through the opening. The baffle is shielded at the opening, the baffle is detachably connected with the base, and the baffle can limit the micro switch.

[0006] Through the above scheme, the receiving cavity is arranged on the base, the micro switch can be installed in the receiving cavity, which not only can provide support for the micro switch, but also can protect the micro switch. The opening arranged on the receiving cavity can facilitate the installation of the micro switch. The baffle shielded at the opening can reduce the probability of the micro switch falling from the base, and improve the use reliability of the auxiliary switch. Moreover, the detachable baffle can limit the micro switch while not hindering the installation and disassembly of the micro switch, thereby reducing the installation and disassembly difficulty of the micro switch.

[0007] In a possible design, the base includes a mounting groove. The mounting groove is arranged on the side wall of the base, and the mounting groove is located at the opening. The baffle is mounted in the mounting groove.

[0008] Through the above scheme, the mounting groove arranged on the side wall of the base can provide a stable basis for the installation of the baffle. When the mounting groove is located at the opening, it can ensure that the baffle can be stably fixed at the opening, thereby reducing the probability that the baffle is displaced in the base and causes the problem that the micro switch cannot be limited. Moreover, the arrangement of the mounting groove can facilitate the installation or disassembly of the baffle.

[0009] In a possible design, the mounting groove has two. The two mounting grooves are opposite, and both of the mounting grooves are through grooves. The baffle includes a first end and a second end, the first end is connected with the first mounting groove, and the second end is connected with the second mounting groove.

[0010] According to the above scheme, the two mounting grooves can facilitate the installation of the baffle. The opposite positions of the two mounting grooves can make the installation of the baffle more stable and reduce the possibility of the baffle tilting during installation. When the mounting grooves are through grooves, the baffle can be more easily installed on the base. The first end of the baffle can be matched with the first mounting groove, and the second end of the baffle can be matched with the second mounting groove, so that the baffle can be detachably connected with the base.

[0011] In a possible design, the mounting groove has two. The two mounting grooves are opposite, and both of the mounting grooves are blind grooves. The baffle includes a first end and a second end, the first end is located in the first mounting groove and is in interference fit with the mounting groove, and the second end is located in the second mounting groove and is in interference fit with the mounting groove.

[0012] According to the above scheme, the two mounting grooves can facilitate the installation of the baffle. The opposite positions of the two mounting grooves can make the installation of the baffle more stable and reduce the possibility of the baffle tilting during installation. When the mounting grooves are blind grooves, the possibility of the first end of the baffle or the second end of the baffle colliding with the structural member outside the auxiliary switch in the frame circuit breaker can be reduced, and the possibility of the first end of the baffle or the second end of the baffle falling off the base when colliding can also be reduced, thereby improving the reliability of the baffle limiting the micro switch. The first end of the baffle can be matched with the first mounting groove, and the second end of the baffle can be matched with the second mounting groove, so that the baffle can be detachably connected with the base.

[0013] In a possible design, the first end or the second end of the baffle is provided with a limiting block. The limiting block is located in the accommodating cavity, and the limiting block abuts against the inner wall of the base.

[0014] According to the above scheme, the limiting block is arranged at the first end or the second end of the baffle, which can limit the baffle without affecting the installation of the baffle. When the baffle is installed, the limiting block abuts against the inner wall of the base, which can limit the baffle by cooperating with the base. In this way, the possibility of the baffle falling off the mounting groove when the auxiliary switch shakes or collides can be reduced, thereby improving the limiting effect of the baffle on the micro switch and improving the use reliability of the auxiliary switch.

[0015] In a possible design, the first end and the second end of the baffle are provided with limiting blocks. The two limiting blocks are located in the accommodating cavity, and the two limiting blocks abut against the inner wall of the base.

[0016] By the above scheme, the limiting blocks at the first end and the second end of the baffle abut against the inner wall of the base after the baffle is installed, and the baffle is limited by the cooperation of the limiting blocks and the base. Moreover, the limiting blocks are arranged at the first end and the second end of the baffle, which can better limit the movement of the baffle, reduce the possibility of the baffle falling from the first mounting groove, and reduce the possibility of the baffle falling from the second mounting groove. In this way, the limiting effect of the baffle on the micro switch can be improved, and the use reliability of the auxiliary switch is improved.

[0017] In a possible design, the micro switch has a plurality of micro switches. The plurality of micro switches are arranged in parallel in the accommodating cavity.

[0018] By the above scheme, the present application provides a plurality of micro switches, which can transmit signals to the user console. Moreover, the plurality of micro switches are arranged in parallel in the accommodating cavity, which can reduce the arrangement of one accommodating cavity. In this way, the volume of the auxiliary switch can be reduced, the arrangement of other parts in the frame circuit breaker is simpler, the complexity of the auxiliary switch during installation and debugging is reduced, the installation flexibility of the auxiliary switch is improved, and the maintenance of the auxiliary switch is simpler.

[0019] In a possible design, the auxiliary switch further comprises a flap and a support. The flap comprises a pressing end and a triggering end corresponding to each other, and the triggering end cooperates with the micro switch. The support is arranged on one side of the base, and the flap is connected to the support through a rotating shaft.

[0020] By the above scheme, the support provides a mounting space for the flap. The flap comprises a pressing end and a triggering end corresponding to each other. The pressing end can be operated by an operator, and the triggering end can trigger a plurality of micro switches at the same time. The flap is connected to the support through a rotating shaft, and when the pressing end moves, the triggering end also moves. In this way, the triggering end can trigger a plurality of micro switches at the same time by triggering the pressing end, which reduces the time cost during operation of the auxiliary switch and improves the operability of the auxiliary switch.

[0021] In a possible design, the pressing end is provided with a reinforcing rib.

[0022] By the above scheme, since the pressing end is in a suspended state for a long time and the flap is thin, the reinforcing rib can increase the strength of the pressing end, reduce the possibility of the pressing end breaking during use of the flap, and improve the use reliability of the flap, thereby improving the use reliability of the auxiliary switch.

[0023] In a second aspect, the application provides a frame circuit breaker, which comprises a middle frame and the auxiliary switch mentioned in the first aspect. The auxiliary switch is installed in the middle frame.

[0024] The frame circuit breaker provided in the second aspect has the advantages of the first aspect and the possible implementation manners of the first aspect, which will not be repeated here. BRIEF DESCRIPTION OF DRAWINGS

[0049] In order for those skilled in the art to better understand the scheme of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings.

[0050] The present application provides a frame circuit breaker, which comprises a middle frame and an auxiliary switch. The auxiliary switch is mounted in the middle frame.

[0051] The frame circuit breaker, also known as a universal circuit breaker, is a mechanical switch electrical appliance capable of connecting, carrying and breaking the current under normal circuit conditions, and also capable of connecting, carrying for a certain time and breaking the current under specified abnormal circuit conditions. The frame circuit breaker can be used to distribute electric energy or protect lines and power supply equipment.

[0052] The frame circuit breaker comprises a middle frame, which has a large capacity and can be equipped with various function trip devices and auxiliary switches. The frame circuit breaker has high breaking capacity and thermal stability, so it is often used in places requiring high breaking capacity and selective protection.

[0053] The auxiliary switch includes a micro switch and a base, and the micro switch is generally installed in the base along the direction of the middle frame towards the base. The auxiliary switch is installed in the middle frame. When the micro switch needs to be repaired or needs to be maintained, the auxiliary switch needs to be removed from the middle frame as a whole, and then the micro switch needs to be removed from the base, which is relatively cumbersome, time-consuming and laborious.

[0054] Based on this, the application provides a frame circuit breaker and an auxiliary switch. The auxiliary switch provided by the application is clearly and completely described below in combination with the drawings.

[0055] Figure 1 The auxiliary switch provided by the application is shown in a schematic view from one angle. Figure 2 The auxiliary switch provided by the application is shown in a schematic view from one angle. Figure 1 The structure of the auxiliary switch provided by the application after the baffle is removed. Figure 3 The auxiliary switch provided by the application is shown in a schematic view from one angle. Figures 1 to 3 As shown in the drawings, the application provides an auxiliary switch, which includes a base 100, a micro switch 200 and a baffle 300. The base 100 is provided with a receiving cavity 110, and the receiving cavity 110 is provided with an opening. The micro switch 200 is installed in the receiving cavity 110 through the opening. The baffle 300 is shielded at the opening, the baffle 300 is detachably connected with the base 100, and the baffle 300 can limit the micro switch 200.

[0056] The base 100 has an installation space inside, and the installation space is the receiving cavity 110. When the auxiliary switch is installed in the middle frame, the opening of the receiving cavity 110 faces away from the installation direction of the auxiliary switch.

[0057] The baffle 300 can be plate-shaped, and the length of the baffle 300 can be the same as the length of the opening, or the length of the baffle 300 can be longer than the length of the opening, so that the baffle 300 can shield the opening.

[0058] The micro switch 200 is a kind of switch with small contact spacing and fast-moving mechanism, and the micro switch 200 performs switching action through a specified stroke and force. The micro switch 200 is usually covered by a shell, and has a driving rod outside. Since the contact spacing of the micro switch 200 is relatively small, the micro switch 200 is also called a sensitive switch or a fast-moving switch. The micro switch 200 is widely used in devices that need to frequently switch circuits, and is used for automatic control and safety protection.

[0059] The process of installing the auxiliary switch in the middle frame can be: first, installing the base 100 in the middle frame, then installing the micro switch 200 into the accommodating cavity 110 from the opening of the accommodating cavity 110, and finally installing the baffle 300 on the base 100 to limit the micro switch 200. Because the baffle 300 shields the opening of the accommodating cavity 110, the probability of the micro switch 200 falling out of the base 100 can be reduced.

[0060] When the micro switch 200 needs to be repaired or needs daily maintenance, the baffle 300 can be removed from the base 100, and the micro switch 200 can be taken out of the accommodating cavity 110.

[0061] In summary, the application sets the accommodating cavity 110 on the base 100, and the micro switch 200 can be installed in the accommodating cavity 110, which not only provides support for the micro switch 200, but also protects the micro switch 200. The opening on the accommodating cavity 110 can facilitate the installation of the micro switch 200. The baffle 300 shields the opening, which can reduce the probability of the micro switch 200 falling out of the base 100 and improve the reliability of the auxiliary switch. In addition, the detachable baffle 300 can limit the micro switch 200 without hindering the installation and removal of the micro switch 200, reducing the difficulty of installing and removing the micro switch 200.

[0062] Figure 4 For Figure 3 The structure diagram of the baffle 300 after assembly from a perspective. As shown in Figure 3 and Figure 4 The base 100 includes a mounting groove 120. The mounting groove 120 is provided on the side wall of the base 100, and the mounting groove 120 is located at the opening, and the baffle 300 is installed in the mounting groove 120.

[0063] The mounting groove 120 can be a groove structure provided on the side wall of the base 100. The mounting groove 120 can be integrally formed with the base 100, or the mounting groove 120 can be provided on the side wall of the base 100 by cutting or carving after the base 100 is formed. The mounting groove 120 is in communication with the accommodating cavity 110, so that the baffle 300 can be installed in the mounting groove 120 when shielding the opening.

[0064] In summary, the mounting groove 120 provided on the sidewall of the base 100 can provide a stable basis for the installation of the baffle 300. When the mounting groove 120 is located at the opening, it can ensure that the baffle 300 can be stably fixed at the opening, reducing the probability of displacement of the baffle 300 in the base 100, which can cause the problem of being unable to limit the microswitch 200. Moreover, the provision of the mounting groove 120 can facilitate the installation or disassembly of the baffle 300.

[0065] The mounting groove 120 can be provided in various ways, and two of the provided ways of the mounting groove 120 will be described below in combination with the drawings, but this does not constitute a limitation on the technical solutions of the present application.

[0066] In a first provided way, the mounting groove 120 has two. The two mounting grooves 120 are opposite to each other, and both of the two mounting grooves 120 are blind grooves. The baffle 300 includes a first end 310 and a second end 320. The first end 310 is located in the first mounting groove 121 and is in interference fit with the first mounting groove 121. The second end 320 is located in the second mounting groove 122 and is in interference fit with the second mounting groove 122.

[0067] The two sidewalls of the base 100 near the opening can each be provided with a mounting groove 120. The distance between the two mounting grooves 120 and the bottom surface of the accommodating cavity 110 is the same, and the distance between the two mounting grooves 120 and the opening is also the same, so that the two mounting grooves 120 are opposite to each other.

[0068] The two mounting grooves 120 can each be a blind groove provided on the sidewall of the base 100, and the two mounting grooves 120 are in the same direction, that is, the first mounting groove 121 can be a blind groove along the direction from the inside of the accommodating cavity 110 to the outside of the sidewall of the base 100, and the second mounting groove 122 can also be a blind groove along the direction from the inside of the accommodating cavity 110 to the outside of the sidewall of the base 100.

[0069] The baffle 300 can be a long strip plate, and the first end 310 of the baffle 300 and the second end 320 of the baffle 300 are opposite to each other. The first end 310 of the baffle 300 can be in interference fit with the first mounting groove 121. The second end 320 of the baffle 300 can be in interference fit with the second mounting groove 122. This can reduce the possibility of the baffle 300 falling off the base 100.

[0070] The baffle 300 has elastic deformation characteristics. When the baffle 300 needs to be installed on the base 100, a certain force can be first applied to the baffle 300 to cause slight bending of the baffle 300, so that the first end 310 of the baffle 300 corresponds to the first mounting slot 121, and the second end 320 of the baffle 300 corresponds to the second mounting slot 122. At this time, the force applied to the baffle 300 is removed, and the baffle 300 restores to its original state under the action of elastic deformation. At this time, the first end 310 of the baffle 300 is located in the first mounting slot 121, and the second end 320 of the baffle 300 is located in the second mounting slot 122.

[0071] When the first setting mode is selected, setting two mounting slots 120 can be more conducive to the installation of the baffle 300. The relative positions of the two mounting slots 120 can make the installation of the baffle 300 more stable, reducing the possibility of tilting of the baffle 300 during installation. When the mounting slot 120 is a blind slot, the possibility of the first end 310 of the baffle 300 or the second end 320 of the baffle 300 colliding with structural members outside the auxiliary switch in the frame circuit breaker can be reduced, and the possibility of the first end 310 of the baffle 300 or the second end 320 of the baffle 300 colliding and the baffle 300 falling off the base 100 can also be reduced, improving the reliability of the baffle 300 limiting the micro switch 200. The first end 310 of the baffle 300 can cooperate with the first mounting slot 121, and the second end 320 of the baffle 300 can cooperate with the second mounting slot 122, so that the baffle 300 can be detachably connected with the base 100.

[0072] Figure 5 A schematic view of a structure of the baffle 300 provided by the embodiments of the present application is shown. The second setting mode is shown in Figures 3 to 5 The mounting slot 120 has two. The two mounting slots 120 are opposite to each other, and both of the two mounting slots 120 are through slots. The baffle 300 includes a first end 310 and a second end 320, the first end 310 is connected with the first mounting slot 121, and the second end 320 is connected with the second mounting slot 122.

[0073] The two side walls of the base 100 near the opening can each be provided with a mounting slot 120. The distance between the two mounting slots 120 and the bottom surface of the accommodating cavity 110 is the same, and the distance between the two mounting slots 120 and the opening is also the same, so that the two mounting slots 120 are opposite to each other. The two mounting slots 120 can each be a through slot penetrating the side wall of the base 100.

[0074] The baffle 300 can be in the shape of a long strip, and the first end 310 of the baffle 300 is opposite the second end 320 of the baffle 300. The first end 310 of the baffle 300 can be clamped with the first mounting slot 121, or the first end 310 of the baffle 300 can be interference fit with the first mounting slot 121. The second end 320 of the baffle 300 can be clamped with the second mounting slot 122, or the second end 320 of the baffle 300 can be interference fit with the second mounting slot 122.

[0075] When the baffle 300 is installed on the base 100, the first end 310 can first pass through the first mounting slot 121, and then the first end 310 passes through the second mounting slot 122, at this time the first end 310 is connected with the second mounting slot 122, and the second end 320 can be connected with the first mounting slot 121 under the action of the first end 310, so that the opening can be shielded by the baffle 300, and the probability of the micro switch 200 falling out of the accommodating cavity 110 can be reduced.

[0076] When the second setting mode is selected, the two mounting slots 120 can be more conducive to the installation of the baffle 300. The two mounting slots 120 opposite to each other can make the installation of the baffle 300 more stable, and reduce the possibility of the baffle 300 tilting during installation. When the mounting slot 120 is a through slot, the baffle 300 can be more easily installed on the base 100. The first end 310 of the baffle 300 can be matched with the first mounting slot 121, and the second end 320 of the baffle 300 can be matched with the second mounting slot 122, so that the baffle 300 can be detachably connected with the base 100.

[0077] For how to limit the baffle 300 and the base 100, the application also makes specific implementation schemes, which will be specifically described below in combination with the drawings, but do not constitute a limitation on the technical solutions of the application.

[0078] As shown in Figure 3 and Figure 5 The first end 310 or the second end 320 of the baffle 300 is provided with a limiting block 330. The limiting block 330 is located in the accommodating cavity 110, and the limiting block 330 abuts against the inner wall of the base 100.

[0079] The limiting block 330 can be a protruding structure provided on the first end 310 of the baffle 300 or the second end 320 of the baffle 300. The limiting block 330 can be in the shape of a cube or a wedge.

[0080] When the limiting block 330 is arranged at the first end 310 of the baffle plate 300, during installation of the baffle plate 300, the second end 320 is first inserted into the first installation slot 121, and then the second end 320 is continuously moved towards the second installation slot 122. Since the base 100 can be elastically deformed, under the extrusion of the limiting block 330, the first installation slot 121 can be slightly expanded. After the limiting block 330 at the first end 310 passes through the first installation slot 121, the sidewall of the base 100 returns to the original state under the action of the elastic deformation, so that the first installation slot 121 also returns to the original state. At this time, the limiting block 330 at the first end 310 abuts against the inner wall of the base 100, and the installation of the baffle plate 300 is completed.

[0081] When the limiting block 330 is arranged at the second end 320 of the baffle plate 300, during installation of the baffle plate 300, the first end 310 is first inserted into the first installation slot 121, and then the first end 310 is continuously moved towards the second installation slot 122. Since the base 100 can be elastically deformed, under the extrusion of the limiting block 330, the first installation slot 121 can be slightly expanded. After the limiting block 330 at the second end 320 passes through the first installation slot 121, the sidewall of the base 100 returns to the original state under the action of the elastic deformation, so that the first installation slot 121 also returns to the original state. At this time, the limiting block 330 at the first end 310 abuts against the inner wall of the base 100, and the installation of the baffle plate 300 is completed.

[0082] In summary, the limiting block 330 arranged at the first end 310 or the second end 320 of the baffle plate 300 can limit the baffle plate 300 without affecting the installation of the baffle plate 300. After the baffle plate 300 is installed, the limiting block 330 abuts against the inner wall of the base 100, and the baffle plate 300 can be limited by the cooperation of the limiting block 330 and the base 100. Thus, the possibility of the baffle plate 300 falling from the installation slot 120 when the auxiliary switch shakes or collides can be reduced, so that the limiting effect of the baffle plate 300 on the microswitch 200 can be improved, and the use reliability of the auxiliary switch is improved.

[0083] Figure 7 After the baffle plate 300 is assembled, the structure of the baffle plate 300 is shown in another view. Figure 3 After the baffle plate 300 is assembled, the structure of the baffle plate 300 is shown in another view. Figure 8 After the baffle plate 300 is assembled, the structure of the baffle plate 300 is shown in another view. Figure 7 The enlarged view of part A in FIG. 6 is shown in FIG. 7. As shown in FIG. 7, the first end 310 and the second end 320 of the baffle plate 300 are both provided with the limiting block 330. Both of the limiting blocks 330 are located in the accommodating cavity 110, and both of the limiting blocks 330 abut against the inner wall of the base 100. Figure 8

[0084] ​The limiting block 330 can be a protruding structure provided at the first end 310 of the baffle 300 and the second end 320 of the baffle 300. The limiting block 330 can be a cubic or wedge shape.

[0085] When the first end 310 and the second end 320 of the baffle 300 are provided with the limiting block 330, during installation of the baffle 300, a force is first applied to the baffle 300 to cause slight deformation of the baffle 300, then the first end 310 of the baffle 300 is aligned with the first installation slot 121, and the second end 320 of the baffle 300 is aligned with the second installation slot 122, and then the force applied to the baffle 300 is removed, and the baffle 300 returns to its original shape under the action of elastic deformation. The first end 310 of the baffle 300 enters the first installation slot 121, the limiting block 330 at the first end 310 of the baffle 300 abuts against one of the inner walls of the base 100, the second end 320 of the baffle 300 enters the second installation slot 122, and the limiting block 330 at the second end 320 of the baffle 300 abuts against the other inner wall of the base 100. At this time, the baffle 300 is installed.

[0086] In summary, the limiting block 330 is provided at the first end 310 and the second end 320 of the baffle 300, and when the baffle 300 is installed, the limiting block 330 abuts against the inner wall of the base 100, and the baffle 300 can be limited by the cooperation of the limiting block 330 and the base 100. Moreover, the limiting block 330 is provided at the first end 310 and the second end 320 of the baffle 300, which can better limit the movement of the baffle 300, reduce the possibility of the baffle 300 falling out of the first installation slot 121, and also reduce the possibility of the baffle 300 falling out of the second installation slot 122. This can improve the limiting effect of the baffle 300 on the micro switch 200 and improve the use reliability of the auxiliary switch.

[0087] As shown in Figures 1 to 3 , the micro switch 200 has a plurality of micro switches. The plurality of micro switches 200 are installed in the accommodating cavity 110 in a side-by-side arrangement.

[0088] Generally, the micro switch 200 has a small volume, so a plurality of micro switches 200 can be placed in the accommodating cavity 110. The micro switch 200 of the present application is further improved, and compared with the micro switch 200 in the prior art, the micro switch 200 of the present application has a smaller volume, so the accommodating cavity 110 of the present application can accommodate more micro switches 200. As shown in the figure, the accommodating cavity 110 of the present application can accommodate at least 8 micro switches 200.

[0089] With the above configuration, this application provides multiple microswitches 200, which can transmit signals to the user control console. Furthermore, the multiple microswitches 200 are arranged side by side in the receiving cavity 110, which can reduce the number of receiving cavities 110. This not only reduces the size of the auxiliary switch and simplifies the arrangement of other parts in the frame circuit breaker, but also reduces the complexity of installation and commissioning of the auxiliary switch, increases the installation flexibility of the auxiliary switch, and makes the maintenance and repair of the auxiliary switch simpler.

[0090] Figure 9 This is a schematic diagram of the structure of the clapper 400 provided in the embodiments of this application. Figure 10 A schematic diagram of the auxiliary switch provided in this application embodiment from another perspective. (See diagram below.) Figure 9 as well as Figure 10 As shown, the auxiliary switch also includes a striking plate 400 and a bracket 500. The striking plate 400 includes a pressing end 410 and a trigger end 420 corresponding to each other, and the trigger end 420 cooperates with the micro switch 200. The bracket 500 is located on one side of the base 100, and the striking plate 400 is connected to the bracket 500 through a rotating shaft.

[0091] like Figure 10 As shown in the diagram, the bracket 500 is positioned below the base 100. One end of the bracket 500 is connected to the base 100, and the other end of the bracket 500 is connected to the clapper plate 400 via a pivot.

[0092] The flap 400 can be plate-shaped, with the two ends being the pressing end 410 and the trigger end 420. During normal use, the operator can operate the pressing end 410, which will simultaneously activate the trigger end 420 under the action of the rotating shaft. At this time, the trigger end 420 can trigger the micro switch 200, causing the micro switch 200 to operate.

[0093] In summary, the bracket 500 provides installation space for the trigger plate 400. The trigger plate 400 includes a corresponding pressing end 410 and a trigger end 420. The pressing end 410 is operated by the operator, and the trigger end 420 can simultaneously trigger multiple micro switches 200. The trigger plate 400 of this application is connected to the bracket 500 via a rotating shaft. When the pressing end 410 is activated, the trigger end 420 will also activate. Thus, only the pressing end 410 needs to be activated to allow the trigger end 420 to simultaneously trigger multiple micro switches 200, reducing the time cost required for auxiliary switch operation and improving the operability of the auxiliary switch.

[0094] Please continue to refer to Figure 9 As shown, the pressing end 410 is provided with reinforcing ribs 411.

[0095] The reinforcing rib 411 is a structural element added in the structural design process to enhance the strength and rigidity of the structure. The reinforcing rib 411 increases the strength of the joint surface by adding a reinforcing plate to the common vertical surface of the two structures. The pressing end 410 of the present application can be provided with a reinforcing rib 411 to improve the strength of the pressing end 410.

[0096] In summary, since the pressing end 410 is in a suspended state for a long time, and the beater 400 is relatively thin, the provision of the reinforcing rib 411 can increase the strength of the pressing end 410, reduce the possibility of the pressing end 410 breaking during use of the beater 400, causing the auxiliary switch to be unable to be used, improve the use reliability of the beater 400, and further improve the use reliability of the auxiliary switch.
