Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, specifically a control cabinet with a locking mechanism to prevent misoperation. Background Technology

[0002] Control cabinets are widely used in power, machinery and other fields. Their cabinet doors usually use ordinary locks or simple latch structures, which are easy to open accidentally due to misoperation or external impact, posing a safety hazard.

[0003] The existing control cabinet doors need to be opened as needed during routine inspections. However, in practice, the existing door handles are too easy to operate, leading to accidental openings. This affects the efficiency of control cabinet inspections and may even result in misoperation.

[0004] Therefore, there is an urgent need for a locking mechanism that is resistant to misoperation, easy to operate, and highly stable, in order to improve the safety and efficiency of the control cabinet. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a control cabinet with an anti-misoperation locking mechanism, which solves the problem of misoperation of the control cabinet door. The locking mechanism can effectively prevent the cabinet door from being opened directly, and at the same time, it can effectively and efficiently open the cabinet door when needed.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a control cabinet with an anti-misoperation locking mechanism, comprising a cabinet body and a cabinet door, wherein the cabinet door is hinged to the cabinet body, and a locking mechanism is provided on the cabinet door, the locking mechanism comprising a rod and a locking tube, a locking tongue fixed on the locking tube, the locking tongue being offset from the cabinet body, and a handle fixed on the outside of the rod, pulling the handle causes the rod to slide and unlock, and rotating the handle causes the locking tongue to rotate to open the cabinet door.

[0007] Furthermore, the locking mechanism also includes a first fixed ring and a second fixed ring. The first fixed ring is fixed to the lock housing, and the inner side of the second fixed ring is rotatably connected to a rotating seat. The rotating seat is fixed to the lock tube, and a torsion spring is provided inside the rotating seat to keep the lock tongue in a lateral state.

[0008] Furthermore: the lock tube is provided with a first slot, a second slot and a rotating groove, and a locking block is fixed on the side wall of the insertion rod. The locking block can slide along the first slot and align with the second slot after rotation, thereby driving the lock tongue to rotate.

[0009] Furthermore: a spring is provided on the inner side of the insertion rod, and the spring is sleeved on the locking tube for automatic reset of the insertion rod.

[0010] Furthermore: a positioning block is fixed on the outside of the cabinet door, which limits the sliding range of the handle. The handle can be rotated if the range is exceeded.

[0011] Furthermore, the handle is provided with a finger ring, which matches the corresponding line on the lock housing, facilitating quick alignment of the locking block and the second locking slot.

[0012] This utility model provides a control cabinet with a locking mechanism to prevent misoperation. Compared with the prior art, it has the following advantages:

[0013] This control cabinet features a lock mechanism to prevent accidental opening. Through a dual safety mechanism of sliding and rotation, it effectively prevents accidental opening of the cabinet door, enhancing security. The internal slots and blocks of the lock tube ensure precise unlocking. A torsion spring automatically resets the lock tongue, reducing manual intervention. A spring-assisted return of the insertion rod makes operation more convenient. A positioning block limits the handle's movement range to prevent accidental operation. The finger ring design improves operational efficiency and facilitates quick alignment of the unlocking position. The overall structure is stable and reliable. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-7 This utility model provides a technical solution: a control cabinet with an anti-misoperation locking mechanism; specifically, it consists of a cabinet body 1 and a cabinet door 2, with the cabinet door 2 hinged to the cabinet body 1. The control cabinet is a well-known technology in the field, and no further details on the control cabinet technology will be provided here. A locking mechanism is provided on the cabinet door 2, which includes a plug rod 6 and a locking tube 14 provided on the cabinet door 2. A locking tongue 8 is fixed on the locking tube 14, and the locking tongue 8 is rotatably offset from the cabinet body 1. A handle 10 is fixed to the outside of the plug rod 6. By pulling the plug rod 6 outward with the handle 10, the safety can be released. Then, by rotating the handle 10, the locking tongue 8 can be rotated. The sliding of the safety mechanism can prevent the cabinet door 2 from being opened by misoperation, and the locking tongue 8 can be operated by sliding and then rotating. This also allows for quick operation of the locking tongue 8. The locking mechanism can stably operate the cabinet door 2 while preventing accidental operation by the operator.

[0024] The locking mechanism also includes a first fixing ring 3 and a second fixing ring 4 fixed to the cabinet door 2. A lock shell 5 is fixed to the first fixing ring 3. A rotating seat 7 is rotatably connected to the inner end of the second fixing ring 4. The rotating seat 7 is fixedly connected to the outer end of the lock tube 14. A torsion spring is fixed inside the rotating seat 7 within the second fixing ring 4. The torsion spring ensures that the lock tongue 8 is always positioned laterally. A first slot 15 is provided inside the lock tube 14, and a second slot 16 is provided at the other end of the lock tube 14. A rotating groove 17 is provided between the slots 16. A locking block 12 is fixed on the side wall of the insertion rod 6. When the insertion rod 6 slides back and forth, the locking block 12 moves back and forth in the first locking groove 15. When it is necessary to rotate to open the cabinet door 2, the insertion rod 6 is slid outward and pulled out. At this time, the locking block 12 is in the rotating groove 17. The handle 10 is rotated to align the locking block 12 with the second locking groove 16. Then, the insertion rod 6 is pulled outward to insert the locking block 12 into the second locking groove 16. Then, the handle 10 is rotated downward to rotate the locking tongue 8 upward, thereby opening the cabinet door 2.

[0025] A spring 13 is fixed to the inner end of the insertion rod 6. The spring 13 is sleeved on the locking tube 14. The spring 13 can pull and rebound when the insertion rod 6 slides back and forth, which can not only prevent accidental operation, but also make it easy to return the handle 10 to its original position.

[0026] A positioning block 18 is fixed on the outside of the cabinet door 2. The positioning blocks 18 are symmetrically arranged. When the insertion rod 6 slides back and forth, the handle 10 moves back and forth within the range of the positioning block 18. When the handle 10 slides out of the positioning block 18, the handle 10 can be rotated accordingly. A lock can be installed through the positioning block 18 to further fix and protect the handle 10.

[0027] A finger ring 11 is fixed on the handle 10. The finger ring 11 matches the corresponding line on the lock shell 5, so that the internal locking block 12 can be matched with the second locking groove 16 through the handle 10 to operate the locking tongue 8, thereby improving the efficiency of operation and rotation.
