Description

Technical Field

[0001] This invention belongs to the field of power distribution equipment technology, and specifically relates to a high-reliability power distribution switch with a locking function. Background Technology

[0002] Switchgear is a key device in power systems used to control the on / off state of circuits, widely used in industrial, building, and civil power distribution. Traditional switchgear suffers from the following technical drawbacks in terms of functionality and safety: 1. Insufficient locking function: Traditional switches lack a reliable locking mechanism, making them prone to accidental switching under vibration or misoperation, leading to safety hazards or equipment damage. 2. Complex mode switching: Switching between normally open (NO) and normally closed (NC) modes requires external tools or complex operations, making it difficult to meet rapid adjustment needs and impacting maintenance efficiency. 3. Inflexible temporary states: Existing switches struggle to achieve temporary on / off states (such as maintenance or testing) in normally open or normally closed modes, requiring complete power disconnection or mechanical bypass, which is cumbersome and may interrupt other circuits. 4. Poor structural stability: The simple design of the guiding and locking mechanisms makes them prone to wear and tear after long-term use, leading to poor contact or positioning misalignment, reducing switch lifespan and reliability.

[0003] In recent years, to address these issues, the industry has proposed solutions such as split-type locking structures and spring-assisted reset, but these still have the following limitations: Locking mechanisms are mostly unidirectional mechanical locks, failing to balance the convenience of manual unlocking with the reliability of automatic locking. Mode switching relies on multi-component linkage, resulting in complex structures and large space requirements, making them difficult to adapt to compact power distribution equipment. Temporary operations require additional buttons or levers, increasing costs and potentially introducing new points of failure. Summary of the Invention

[0030] In a preferred embodiment, please refer to Figure 8 The switching locking assembly 500 includes a first locking tooth ring 501 and a second locking tooth ring 502. A tensioning horizontal plate 506 is provided in the middle of the second locking tooth ring 502.

Limiting round rods 505 are fixedly provided at both ends of the tensioning horizontal plate 506. A tensioning spring 503 is fixedly provided on the tensioning bottom plate 504.

[0031] In this embodiment, the switching locking assembly 500 is disposed inside the housing 102, the first locking toothed ring 501 is fixed on the switching end plate 407, the second locking toothed ring 502 is located inside the housing horizontal plate 113, the limiting round rod 505 slides in the housing smooth hole 111, and the two ends of the top spring 503 are respectively fixed on the top plate 504 and the housing smooth hole 111.

[0032] The working principle of this invention is as follows: When this invention is used, two modes are formed between the energized rod assembly 200 and the switch switching assembly 400. Through the rotation of the switch switching assembly 400, when the first distribution plate 402 extends forward and the second distribution plate 405 retracts, a normally open power distribution structure is formed between the energized rod assembly 200 and the switch switching assembly 400. Specifically, the rotation of the switching shaft 403 drives the switching gear 404 to rotate. Since the switching gear 404 forms a misaligned power distribution structure with the first toothed arm 401 and the second toothed arm 406, when the first distribution plate 402 extends forward and the second distribution plate 405 retracts, the return spring 201... With the push of the pusher, the energized guide rod 202 on the energized guide rod assembly 200 naturally moves upward and comes into contact with the first distribution board 402. At this time, the energized guide rod 202 and the first distribution board 402 form a constant contact structure. In this way, the normally open power distribution mode of the power distribution switch housing assembly 100 is realized. When temporary disconnection is required, the energized guide rod assembly 200 is pressed down by the pressing cap 207. At this time, the pressing square rod 204 moves down and drives the energized guide rod 202 to move down. The return spring 201 is compressed, and the energized guide rod 202 and the first distribution board 402 form a non-contact structure, thus realizing the temporary disconnection of the power distribution switch housing assembly 100 in the normally open mode.

[0033] In another mode of use, the switch switching assembly 400 rotates in the opposite direction to the aforementioned direction. At this time, the first distribution board 402 retracts and the second distribution board 405 extends forward, forming a normally closed power distribution structure between the energizing rod assembly 200 and the switch switching assembly 400. Specifically, the reverse rotation of the switching shaft 403 drives the switching gear 404 to rotate in the opposite direction. Since the switching gear 404 forms a misaligned power distribution structure with the first gear arm 401 and the second gear arm 406, when the first distribution board 402 retracts and the second distribution board 405 extends forward, the energizing rod assembly 200 is activated by the push of the return spring 201. The energizing rod 202 on the 0 naturally moves upward and forms a structure that is always not in contact with the second distribution board 405. At this time, the energizing rod 202 and the second distribution board 405 form a structure that is always not in contact. In this way, the normally closed power distribution mode of the power distribution switch housing assembly 100 is realized. When temporary power is required, the energizing rod assembly 200 is pressed down by pressing the pressing cap 207. The pressing square rod 204 moves down and drives the energizing rod 202 to move down. The return spring 201 is compressed. At this time, the energizing rod 202 and the second distribution board 405 form a contact structure, that is, the temporary power supply in the normally closed mode of the power distribution switch housing assembly 100 is realized.

[0034] Based on the above, when the energized guide rod assembly 200 is adjusted by pressing or fixed in its normal state, a guide rod locking assembly 300 is provided at the rear end of the energized guide rod assembly 200. When it is necessary to lock the position of the energized guide rod assembly 200, the locking tooth plate 301 on the guide rod locking assembly 300 will approach the toothed arm 206 on the energized guide rod assembly 200 by the tension of the tension spring 304. The energized guide rod assembly 200 is locked by the meshing of the locking tooth plate 301 and the toothed arm 206. When unlocking, the guide rod locking assembly 300 is pushed backward by the stop plate 305. At this time, the tension spring 304 is stretched, and the locking tooth plate 301 and the toothed arm 206 are released from lock. When releasing the lock, the bolt 306 is tightened to fix and maintain the unlocked state.

[0035] Based on the above, the switching shaft 403 drives the switching gear 404 to rotate. The rotation and reverse rotation of the switching gear 404 are achieved by actuating the switching ring 409. The end of the switch switching assembly 400 of this invention is provided with a switching locking assembly 500, which locks the rotational position of the switch switching assembly 400. Specifically, the first locking toothed ring 501 is fixed on the switching end plate 407, the second locking toothed ring 502 is located inside the casing horizontal plate 113, the limiting round rod 505 slides within the casing smooth hole 111, and the two ends of the tightening spring 503 are respectively fixed on the tightening base plate 504 and the casing smooth hole 111. When the switching gear 404 rotates, due to the first locking... The locking ring 501 and the switching gear 404 are coaxially arranged. At this time, the first locking ring 501 rotates synchronously. When the first locking ring 501 rotates, the protruding structure on the first locking ring 501 will compress the protruding structure of the second locking ring 502. As the first locking ring 501 continues to rotate, the protruding structure on the first locking ring 501 will re-mesh with the concave structure of the second locking ring 502. In this way, the cyclic meshing locking and unlocking between the first locking ring 501 and the second locking ring 502 is realized. In this way, it is convenient to adjust the rotation state of the switch switching component 400 on the one hand, and convenient to lock the rotation state of the switch switching component 400 in a timely manner on the other hand.
