Description

Technical Field

[0001] This utility model relates to the field of power equipment safety interlocking technology, and in particular to a high-reliability interlocking distribution cabinet. Background Technology

[0002] With the increasing demands for intelligence and safety in power systems, the operation and maintenance of distribution cabinets require quick locking and unlocking of cabinet doors, which necessitates the use of interlocking mechanisms. In practical use, interlocking mechanisms with similar structures still have many defects, such as: existing interlocking mechanisms are not convenient to unlock quickly, the operation is cumbersome and relies on the cooperation of multiple people, and existing interlocking mechanisms are not convenient to lock stably, are easily affected by vibration or accidental touch, leading to accidental opening, and are not convenient to reset and prevent misoperation. After unlocking, safety hazards may be caused by failure to reset in time. Therefore, it is necessary to design a highly reliable interlocking distribution cabinet. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a highly reliable interlocking power distribution cabinet.

[0004] This utility model is achieved using the following technical solution: a high-reliability interlocking distribution cabinet, for the distribution cabinet body, wherein a cabinet door is hinged to the outer surface of the distribution cabinet body, and a turning connection part is fixedly connected to the outer surface of the cabinet door, and an embedded groove is provided inside the turning connection part; it also includes: The fixing component includes a fixing frame fixedly connected to the outer surface of the power distribution cabinet body, and wedge tenons slidably installed inside the fixing frame at the top and bottom of the movable groove; a limiting groove is opened at the rear end of the fixing frame, a limiting block is slidably installed inside the limiting groove, and a push plate is fixedly connected to the outer surface of the limiting block; The disassembly assembly includes a push plate slidably mounted on the outer surface of the mounting bracket. A handle is fixedly connected to one side of the outer surface of the push plate, and a second damper is fixedly connected to the side of the outer surface of the push plate away from the handle. The side of the second damper away from the push plate is fixedly connected to the outer surface of the distribution cabinet body.

[0005] As a further improvement to the above solution, the fixed frame has an internal movable groove, and a first damper is fixedly connected to the inner wall of the movable groove.

[0006] The above technical solution utilizes the buffering effect of the first damper to slow down the descent speed of the fixed plate, reduce mechanical vibration, prevent the fixed plate from impacting the movable groove and causing structural wear, and extend the equipment life.

[0007] As a further improvement to the above solution, a fixing plate is fixedly connected to the side of the first damper away from the inner wall of the movable groove, and the fixing plate is slidably installed inside the movable groove.

[0008] Through the above technical solution, the slow-release insertion of the wedge tenon is achieved by linking the first damper with the fixed plate, which enhances the locking stability and reduces mechanical impact.

[0009] As a further improvement to the above solution, the bottom of the fixing plate is fixedly connected with a wedge tenon, the top wedge tenon and the bottom wedge tenon are matched, and the wedge tenon is set inside the embedded groove.

[0010] The above technical solution utilizes the geometric self-locking characteristics of the wedge tenon to achieve rapid locking of the cabinet door, preventing accidental opening. The wedge tenon and the inclined surface of the embedded groove form a self-locking force, improving locking reliability.

[0011] As a further improvement to the above solution, a force-bearing plate is fixedly connected to the outer surface of the fixing plate, and the force-bearing plate is matched with the push plate.

[0012] The above technical solution reduces the required operating force by leveraging the push plate and the force plate, enabling quick unlocking with one hand while ensuring accurate force transmission and avoiding unlocking failure.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a fixed plate that descends under the slow-release effect of a first damper, causing the top and bottom wedge tenons to insert into the embedding groove. The wedge tenons contact the inclined surface of the embedding groove to form a self-locking force, while the damper slows down the descent speed of the fixed plate. Through the geometric self-locking characteristics of the wedge tenons, the cabinet door is quickly locked to prevent accidental opening. The damper reduces mechanical vibration, avoids structural wear caused by the fixed plate impacting the movable groove, and extends the equipment's lifespan.

[0014] This invention uses a push plate to slide by pressing the handle. The inclined surface abuts against the force plate to form a lever effect. When the handle is released, the second damper pushes the push plate to reset, and the fixed plate descends again under the action of the first damper. The lever design utilizes the cooperation of the inclined surfaces of the push plate and the force plate to reduce the operating force required and achieve quick unlocking with one hand. The first and second dampers ensure that there is no impact during the reset process of the push plate and the fixed plate, avoiding mechanical vibration or jamming. After reset, the wedge tenon automatically returns to the locked state to prevent unauthorized personnel from accidentally opening the cabinet door. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0018] Please combine Figure 1-5 This embodiment provides a high-reliability interlocking distribution cabinet, comprising a cabinet body 101. A cabinet door 102 is hinged to the outer surface of the cabinet body 101. A turning connection portion 103 is fixedly connected to the outer surface of the cabinet door 102, and an embedded groove 104 is provided inside the turning connection portion 103. The aforementioned distribution cabinet also includes: Fixing component 2 includes a fixing frame 201 fixedly connected to the outer surface of the power distribution cabinet body 101, and wedge tenons 205 are slidably installed inside the fixing frame 201 at the top and bottom of the movable groove 202. Disassembly component 3, which includes a push plate 302 that is slidably mounted on the outer surface of the fixing frame 201.

[0019] The fixed frame 201 has an internal movable groove 202, and the inner wall of the movable groove 202 is fixedly connected to a first damper 203.

[0020] A fixing plate 204 is fixedly connected to the side of the first damper 203 away from the inner wall of the movable groove 202, and the fixing plate 204 is slidably installed inside the movable groove 202.

[0021] The bottom of the fixing plate 204 is fixedly connected with a wedge tenon 205, the top wedge tenon 205 and the bottom wedge tenon 205 are matched, and the wedge tenon 205 is set inside the embedded groove 104.

[0022] A force-bearing plate 206 is fixedly connected to the outer surface of the fixed plate 204, and the force-bearing plate 206 is matched with the push plate 302.

[0023] After the steering connection 103 is fully inserted into the movable groove 202, the fixed plate 204 descends under the slowing effect of the first damper 203, causing the top and bottom wedge tenons 205 to insert into the embedded groove 104, preventing the cabinet door 102 from opening accidentally. The damper slows down the descent speed of the fixed plate 204, reducing mechanical vibration, and the self-locking characteristic of the wedge tenons 205 achieves fast and stable locking.

[0024] A limiting groove 207 is provided at the rear end of the fixed frame 201. A limiting block 303 is slidably installed inside the limiting groove 207. A push plate 302 is fixedly connected to the outer surface of the limiting block 303.

[0025] A handle 301 is fixedly connected to one side of the outer surface of the push plate 302. A second damper 304 is fixedly connected to the side of the outer surface of the push plate 302 away from the handle 301. The side of the second damper 304 away from the push plate 302 is fixedly connected to the outer surface of the power distribution cabinet body 101.

[0026] As the push plate 302 continues to advance, the force plate 206 is lifted, and the fixed plate 204 moves upward against the resistance of the first damper 203. At this time, the top and bottom wedge tenons 205 are released from self-locking, canceling the locking of the steering connection 103. After releasing the handle 301, the second damper 304 pushes the push plate 302 back to the initial position, releasing the pressure on the force plate 206. The fixed plate 204 descends again under the action of the first damper 203, and the wedge tenons 205 are inserted into the embedded groove 104 again, completing the relocking of the steering connection 103.

[0027] The specific operating principle of the cabinet door interlock in the embodiment of this application is as follows: When the cabinet door 102 rotates around the cabinet body 101 to the front end, the turning connection part 103 on its outer surface is just embedded in the movable groove 202 of the fixed frame 201. At this time, the side wall of the turning connection part 103 is initially aligned with the inner wall of the movable groove 202, preparing for subsequent locking. After the turning connection part 103 is fully inserted into the movable groove 202, the fixed plate 204 descends under the slowing action of the first damper 203, driving the top and bottom wedge tenons 205 to insert into the embedded groove 104, preventing the cabinet door 102 from opening accidentally. The damper slows down the descent speed of the fixed plate 204, reducing mechanical vibration. The self-locking characteristic of the wedge tenon 205 achieves fast and stable locking. When cabinet door 102 needs to be unlocked, the operator presses the handle 301, causing the push plate 302 to slide along the limit block 303. The inclined surface of the outer surface of the push plate 302 abuts against the inclined surface of the force plate 206, forming a lever effect. The limit design ensures that the push plate 302 moves linearly and avoids jamming. The damper optimizes the operating feel and prevents forced unlocking. As the push plate 302 continues to advance, the force plate 206 is lifted, and the fixed plate 204 moves upward against the resistance of the first damper 203. At this time, the top and bottom wedge tenons 205 release their self-locking, canceling the locking of the steering connection 103. After releasing the handle 301, the second damper 304 pushes the push plate 302. Returning to the initial position, the pressure on the load-bearing plate 206 is released, and the fixed plate 204 descends again under the action of the first damper 203. The wedge tenon 205 is inserted into the embedded groove 104 again, completing the relocking of the steering connection 103. The dual damper design realizes smooth unlocking and reset, extending the service life of the equipment. After reset, it automatically returns to the locked state to prevent misoperation. The cooperation between the limit groove 207 and the limit block 303 ensures that the push plate 302 can only move in the preset direction, avoiding structural deformation caused by lateral force. At the same time, when the cabinet door 102 is closed, the rigid contact between the steering connection 103 and the fixed frame 201 provides additional support and enhances the overall stability.

[0028] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
