Description

Technical Field

[0001] The utility model relates to the technical field of switch devices, and in particular to a switch device with a lock assembly. Background Art

[0002] A switchgear is an electrical device used to close or open one or more circuits. To ensure proper operation, this type of equipment requires regular inspection of its internal components for damage, such as worn contacts and spring failure. Therefore, the switchgear must be removably connected to the device body, allowing operators to visually inspect its internal components for damage.

[0003] Currently, switchgear typically includes a switch base, which is detachably connected to the device body through a threaded connection. Therefore, when removing the switch base, the rotation angle of the switch base is affected by the length of its threads. To ensure the connection strength between the switch base and the device body, the thread length of the switch base is often designed to be long, requiring the operator to rotate the switch base multiple times to remove it from the device body. Furthermore, during the removal process, the operator may mistakenly rotate the switch base counterclockwise when the intended direction is clockwise, thus affecting the efficiency of the switchgear removal. Utility Model Content

[0004] The utility model provides a switch device with a locking assembly, which solves the problem in the related art that the switch seat needs to be rotated to remove the switch seat from the device body, thereby improving the disassembly efficiency of the switch device.

[0005] The technical solution of the utility model is as follows:

[0006] A switch device with a lock assembly includes a switch structure and a lock assembly for fixing the switch structure. The switch structure includes a switch base and a switch body. The lock assembly includes a fixed base and a trigger card. The trigger card is rotatably connected to the fixed base and is used to fix the switch base. The trigger card is provided with a positioning hole for providing a switch base for embedding. The hole wall of the positioning hole is provided with a plurality of fixed card blocks. The switch base is provided with a plurality of limit card slots for each fixed card block to be embedded one by one. Each of the limit card slots is an inverted "L"-shaped structure.

[0007] Furthermore, a snap assembly is provided between the pull clamp and the fixed seat; the snap assembly includes an elastic clamp and a fixed slot, the fixed slot is opened on the fixed seat, the elastic clamp is fixedly connected to the pull clamp, and the elastic clamp is clamped to the fixed slot.

[0008] Furthermore, the elastic clip includes a clipping part, a pressing part, and a connecting part, and the clipping part, pressing part, and connecting part are integrally formed. The connecting part is fixedly connected to the pull clip, and the distance between the pressing part and the connecting part is greater than the distance between the clipping part and the connecting part, and the clipping part abuts against the fixed slot.

[0009] Furthermore, each of the limit slots includes a sliding portion and a fixed portion, and an anti-stuck slope is provided between each of the fixed portion and the sliding portion. The horizontal height of one end of the anti-stuck slope close to the fixed portion is higher than the horizontal height of one end of the anti-stuck slope close to the sliding portion, and the fixed block abuts against the fixed portion.

[0010] Furthermore, the length of the projection of the sliding portion on the horizontal plane is greater than the length of the projection of the fixed block on the horizontal plane.

[0011] Furthermore, the groove walls and the anti-stuck inclined surfaces of each sliding portion are all arranged at an incline.

[0012] Furthermore, the clamping portion is a right-angled triangle structure.

[0013] Furthermore, the pressing portion is provided with a plurality of anti-slip strips, and the cross section of each of the anti-slip strips is a triangular structure.

[0014] The working principle and beneficial effects of the utility model are as follows:

[0015] The switch base in the present invention is equipped with a lock assembly, which mainly includes a fixed base and a pull clamp. The pull clamp is rotatably connected to the fixed base, and the pull clamp is provided with a positioning hole for embedding the switch base and a plurality of fixed blocks. In order to prevent the presence of the fixed blocks from affecting the normal embedding work of the switch base, the switch base is provided with a plurality of limit slots, each of which corresponds to each fixed block one by one, to ensure that the switch base can be normally embedded in the pull clamp.

[0016] At the same time, each limit slot is an inverted "L"-shaped structure. In this way, after the switch seat is embedded in the pull card (lock assembly), it can use the influence of gravity to quickly find the fixed position of the lock assembly on it. Then the pull card can be rotated to make the fixed card block on the pull card fit into the specified position of the limit slot. Through the mutual engagement of the two, the switch seat is finally constrained from moving in the vertical and horizontal directions, thereby realizing the fixing of the switch seat.

[0017] Similarly, when the switch structure needs to be disassembled, the fixed block can be disengaged from the specified position of the limit slot by rotating the card in the opposite direction, and then the switch seat can be directly pulled along the vertical or horizontal plane to realize the disassembly of the switch structure. Compared with the switch seat fixed with threads, there is no need to rotate the switch seat at a large angle during the disassembly process, which greatly improves the disassembly efficiency of the switch structure.

DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] like Figures 1 and 2 、 Figures 4 to 6 As shown, this embodiment provides a switch device with a locking assembly, which mainly includes a switch structure 1 and a locking assembly 2 for fixing the switch structure 1.

[0030] The switch structure 1 in this embodiment is preferably a switch structure that is easily triggered, such as a push-button switch structure. It primarily comprises a switch base 11, a switch trigger unit (spring, contacts, button), and other structures. The latch assembly 2 primarily comprises a fixed base 21 and a triggering member 22. The triggering member 22 is rotatably connected to the fixed base 21 and is used to secure the switch base 11. Specifically, the triggering member 22 is provided with a positioning hole 221 for the switch base 11 to be inserted into. The fixed base 21 also has a corresponding mating hole, allowing the switch structure 1 and the latch assembly 2 to achieve hole-axis mating, constraining the switch base 11 (switch structure 1), thereby facilitating the securement of the switch structure 1. Several fixing blocks 222 are provided on the walls of the positioning holes 221. Each fixing block 222 is integrally formed with the triggering member 22 to ensure the strength of the connection between the two. The switch base 11 is provided with a plurality of limit slots 211 for each fixing block 222 to be inserted one by one, so as to prevent the presence of each fixing block 222 from affecting the normal insertion of the switch base 11. At the same time, the fixing blocks 222 are evenly distributed around the central axis of the positioning hole 221, thereby ensuring the force balance and stability after the limit slots 211 and the fixing blocks 222 are interlocked with each other.

[0031] Each limiting slot 211 is an inverted "L" shaped structure. Specifically, each limiting slot 211 includes a sliding portion 2111 and a fixed portion 2112. The top of the sliding portion 2111 intersects with the fixed portion 2112, and the top of the fixed portion 2112 is flush with the top of the sliding portion 2111. In this way, after the switch seat 11 is inserted into the positioning hole 221, the switch seat 11 can move downward under the influence of gravity until the sliding portion 2111 is inserted into the positioning hole 221. 1 abuts against the fixed block 222. Subsequently, by rotating the pull clamp 22, the fixed block 222 on the pull clamp 22 slides into the fixed portion 2112, so that the fixed block 222 abuts against the fixed portion 2112 (the top and bottom ends of the fixed block 222 abut against the top and bottom ends of the fixed portion 2112), thereby restricting the movement of the switch base 11 in the vertical and horizontal plane directions, thereby achieving the fixation of the switch base 11 (switch structure 1).

[0032] Similarly, when the switch structure 1 needs to be removed, the pull clamp 22 can be rotated in the opposite direction to move the fixed blocks 222 on the pull clamp 22 back to the corresponding sliding parts 2111. Then, the switch base 11 can be directly lifted and pulled to move the switch base 11 upward in the vertical horizontal plane direction to achieve the removal of the switch structure 1. Compared with the switch base 11 fixed with threads, the switch base 11 in this embodiment does not need to be rotated at a large angle during the disassembly process, which greatly improves the disassembly efficiency of the switch structure 1.

[0033] At the same time, an anti-stuck slope 2113 is provided between each fixed portion 2112 and the sliding portion 2111, and the horizontal height of the anti-stuck slope 2113 close to the fixed portion 2112 is higher than the horizontal height of the anti-stuck slope 2113 close to the sliding portion 2111, that is, the junction between the fixed portion 2112 and the sliding portion 2111 is chamfered to prevent the sharp angle at the junction between the fixed portion 2112 and the sliding portion 2111 from affecting the movement process of the fixed card block 222 into the fixed portion 2112, so that the locking assembly 2 can fix the switch structure 1 more smoothly.

[0034] Furthermore, in order to ensure the stability of the lock assembly 2 fixing the switch structure 1, as shown in FIG. Figures 2 and 3 As shown, a snap assembly 3 is provided between the pull card 22 and the fixed seat 21 in this embodiment. The snap assembly 3 includes an elastic card 31 and a fixed slot 32. The fixed slot 32 is opened on the fixed seat 21. The elastic card 31 is fixedly connected to the pull card 22, and the elastic card 31 is snapped with the fixed slot 32. That is, through the snapping work of the elastic card 31 and the fixed slot 32, the pull card 22 cannot be rotated in the opposite direction, so that the pull card 22 has a self-locking performance, which ensures the reliability of the lock assembly 2 in fixing the switch structure 1.

[0035] Specifically, the elastic clip 31 includes a snap-fit ​​portion 311, a pressing portion 312, and a connecting portion 313. The snap-fit ​​portion 311, the pressing portion 312, and the connecting portion 313 are integrally formed to ensure the stability and strength of the overall structure of the elastic clip 31. In this embodiment, the elastic clip 31 is preferably made of polypropylene, which provides the elastic clip 31 with a certain degree of heat resistance and toughness, thereby ensuring its overall structural strength and extending its service life.

[0036] The engaging portion 311 abuts against the fixed slot 32, thereby securing the pull clamp 22 to the fixed base 21 under the action of the buckle assembly 3. The connecting portion 313 is fixedly connected to the pull clamp 22. The distance between the pressing portion 312 and the connecting portion 313 is greater than the distance between the engaging portion 311 and the connecting portion 313, making the elastic clamp 31 as a whole present a labor-saving lever structure. This makes it convenient for a worker to disengage the engaging portion 311 from the fixed slot 32 by pressing the pressing portion 312, thereby improving the practicality of this embodiment.

[0037] The clamping portion 311 is a right-angled triangle structure, that is, the projection surface of the clamping portion 311 on the horizontal plane is a right-angled triangle structure, so that it can use the stability of the triangular structure to avoid the clamping portion 311 from being deformed due to force when abutting the fixed slot 32, thereby ensuring the fixing effect of the elastic clamp 31 on the pull clamp 22; at the same time, it is also convenient for the clamping portion 311 to disengage from the fixed slot 32 when the staff presses the pressing portion 312.

[0038] The pressing portion 312 is provided with a plurality of anti-slip strips 3121, which increase the friction between the staff and the pressing portion 312 when the staff contacts the pressing portion 312, prevent slipping, and facilitate the staff to use this embodiment; each anti-slip strip 3121 is integrally formed with the pressing portion 312, and the cross-section of each anti-slip strip 3121 is a triangular structure, which ensures the structural strength of the anti-slip strip 3121 and extends its service life.

[0039] Example 2

[0040] On the basis of Example 1, the length of the projection of the sliding portion 2111 on the horizontal plane in this embodiment is greater than the length of the projection of the fixed block 222 on the horizontal plane, that is, the opening length of the limiting slot 211 in the axial direction of the positioning hole 221 is less than the length of the fixed block 222, which makes it easier for the staff to insert the switch seat 11 into the lock assembly 2, and the fixed block 222 and the limiting slot 211 still retain the groove block fit, and the two can still play a role in mutual restraint.

[0041] Example 3

[0042] like Figures 4 and 5 As shown, on the basis of Example 1 or Example 2, the groove walls and the anti-stuck inclined surfaces 2113 of each sliding portion 2111 in this embodiment are all inclined, that is, the opening width of the sliding portion 2111 of the limiting groove 211 in the circumferential direction of the positioning hole 221 is lower than the groove bottom width of the limiting groove 211, and the opening width of the anti-stuck inclined surface 2113 of the limiting groove 211 in the circumferential direction of the positioning hole 221 is lower than the groove bottom width of the limiting groove 211, thereby reducing the contact area between the fixed block 222 and the limiting groove 211 when it slides into the fixed portion 2112, reducing the friction between the two, and facilitating the sliding work of the fixed block 222.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
