Multi-locking wiring cabinet

Abstract

The utility model relates to a multi-locking wiring cabinet, which is characterized in that one end of a guide plate swings along with the rotation of a handle by rotating the handle so as to drive a movable plate to move, and the movement direction of the movable plate can be limited under the mutual cooperation of a guide rod assembly and a limiting hole, so that the movable plate can move in the limiting hole under the limitation of the guide assembly. Therefore, locking and unlocking of the wiring cabinet can be completed. Due to the fact that the number of the lock tongues is multiple, after the lock tongues enter the lock holes, connection between the cabinet door and the cabinet body is firmer, the gap between the cabinet door and the cabinet body becomes smaller, external dust is not prone to entering the cabinet body, and meanwhile the overall shockproof performance, safety and prying-resistant performance of the wiring cabinet are improved.

Description

Technical Field

[0001] This utility model relates to the field of junction boxes, and in particular to a junction box with multiple locking mechanisms. Background Technology

[0002] A junction box is an enclosed structure used for the installation, protection, and management of electronic equipment. It consists of a cabinet and a door. The door is usually equipped with a lock, which secures the door to the cabinet. Only after the lock is unlocked can the door be rotated to open the junction box.

[0003] However, since the door locks on existing junction boxes usually only have one latch, the connection between the cabinet door and the cabinet body is not strong enough and there are gaps. This not only makes it easy for external dust to enter the cabinet, but also affects the overall shock resistance, security and anti-pry performance of the junction box. It can only achieve basic sealing function and cannot be used in some high-requirement scenarios. Utility Model Content

[0004] Therefore, it is necessary to provide a multi-locking junction box to solve the technical problems existing in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A multi-locking junction box includes: a cabinet body and a cabinet door. The cabinet door is rotatably mounted on the side wall of the cabinet body to open and close the opening of the cabinet body. A flat lock is provided on the outer surface of the cabinet door. The flat lock includes: a handle and a locking rod. The handle is connected to the locking rod. One end of the locking rod protrudes from the inner surface of the cabinet door. A guide plate is fixedly connected to the locking rod. A movable plate is provided at one end of the guide plate near the cabinet door. The guide plate is pivotally connected to the movable plate. A guide rod assembly is provided on the inner surface of the cabinet door. A limit hole is provided on the movable plate. The guide rod assembly passes through the limit hole. A plurality of locking tongues that can move with the movable plate are provided on one side of the movable plate. The cabinet body is provided with a plurality of lock holes corresponding to the locking tongues.

[0007] In one embodiment, the surface of the movable plate has a movable hole, through which the locking rod passes.

[0008] In one embodiment, the guide rod assembly includes a support rod and a guide rod, wherein a first end of the support rod is connected to the inner surface of the cabinet door, the end face of the second end of the support rod abuts against the movable plate, and the guide rod is connected to the second end of the support rod and passes through the limiting hole.

[0009] In one embodiment, a lock hole rod is provided inside the placement cavity of the cabinet, and each lock hole is formed on the lock hole rod.

[0010] In one embodiment, a support frame is provided on the inner surface of the cabinet door, and a plurality of lock tongues pass through the support frame and are arranged at equal intervals vertically.

[0011] In one embodiment, a soft padding layer is provided on the side of the cabinet near the cabinet door.

[0012] In one embodiment, a limiting block is provided on the outer surface of the cabinet, and the limiting block is located on the side of the cabinet door to limit the rotation angle of the cabinet door.

[0013] The beneficial effects of this utility model are as follows: By providing a multi-locking junction box, after the flat lock is unlocked, the handle can rotate freely. At this time, one end of the guide plate swings with the rotation of the handle, driving the movable plate to move. The movement direction of the movable plate can be limited by the cooperation of the guide rod assembly and the limiting hole, so that the movable plate can move within the limiting hole under the restriction of the guide assembly, thereby completing the locking and unlocking of the junction box. Since there are multiple locking tongues, when each locking tongue enters each lock hole, the connection between the cabinet door and the cabinet body is more solid and the gap between the cabinet door and the cabinet body is smaller, making it difficult for external dust to enter the cabinet body. At the same time, it also improves the overall shock resistance, safety and anti-pry performance of the junction box. Attached Figure Description

Detailed Implementation

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a multi-locking junction box includes: a cabinet body 10 and a cabinet door 20. The cabinet door 20 is rotatably mounted on the side wall of the cabinet body 10 to open and close the opening of the cabinet body 10. A flat lock 30 is provided on the outer surface of the cabinet door 20. The flat lock 30 includes: a handle 33 and a locking rod 31. The handle 33 is connected to the locking rod 31. One end of the locking rod 31 protrudes from the inner surface of the cabinet door 20. A guide plate 32 is fixedly connected to the locking rod 31. The guide plate 32 is close to the cabinet door 20. A movable plate 40 is provided at one end, and a guide plate 32 is pivotally connected to the movable plate 40. A movable hole 41 is provided on the surface of the movable plate 40, and the locking rod 31 passes through the movable hole 41. A guide rod assembly 43 is provided on the inner surface of the cabinet door 20. A limit hole 42 is provided on the movable plate 40, and the guide rod assembly 43 passes through the limit hole 42. A plurality of locking tongues 52 that can move with the movable plate 40 are provided on one side of the movable plate 40, and a plurality of lock holes 61 corresponding to the locking tongues 52 are provided on the cabinet body 10.

[0022] Specifically, in use, the flat lock 30 is first unlocked, allowing the handle 33 to rotate freely. Rotating the handle 33 counterclockwise or clockwise causes the locking rod 31 to rotate synchronously. At this time, one end of the guide plate 32 swings with the rotation of the handle 33. Since the other end of the guide plate 32 is pivotally connected to the movable plate 40, the swinging guide plate 32 drives the movable plate 40 to move. The guide rod assembly 43, in cooperation with the limiting hole 42, limits the direction of movement of the movable plate 40, allowing it to move within the limiting hole 42 under the constraint of the guide assembly. Furthermore, the movable hole 41 has a certain width, ensuring that the movable plate 40 and the locking tongue 52 do not interfere with each other when moving. This allows the locking tongues 52 driven by the movable plate 40 to enter or exit the respective lock holes 61, thereby completing the locking and unlocking of the junction box. Since there are multiple locking tongues 52, when each locking tongue 52 enters its respective lock hole 61, the connection between the cabinet door 20 and the cabinet body 10 becomes more secure, and the gap between the cabinet door 20 and the cabinet body 10 becomes smaller, making it difficult for external dust to enter the cabinet body 10. Simultaneously, it improves the overall shock resistance, security, and anti-pry performance of the junction box. It should be noted that the structure of the unlocking handle 33 of the flat lock 30 and the structure of the handle 33 driving the locking rod 31 to rotate are described in Chinese invention application CNA118911526A; therefore, the structure of this flat lock 30 will not be described in detail.

[0023] In one embodiment, such as Figure 2 As shown, a limiting block 11 is provided on the outer surface of the cabinet 10. The limiting block 11 is located on the side of the cabinet door 20 to limit the rotation angle of the cabinet door 20. Specifically, when the latch 52 retracts from the lock hole 61, the cabinet door 20 can be rotated to open the wiring cabinet. When the cabinet door 20 rotates to a certain angle, it will abut against the limiting block 11. At this time, the cabinet door 20 cannot continue to rotate, thereby preventing the cabinet door 20 of the wiring cabinet installed against the wall from hitting the wall.

[0024] In one embodiment, such as Figure 2 and Figure 3 As shown, the guide rod assembly 43 includes a support rod 431 and a guide rod 432. The first end of the support rod 431 is connected to the inner surface of the cabinet door 20, and the end face of the second end of the support rod 431 abuts against the movable plate 40. The guide rod 432 is connected to the second end of the support rod 431 and passes through the limiting hole 42. Specifically, the support rod 431 further supports the movable plate 40, allowing the movable plate 40 to move smoothly horizontally under the support of the guide rod 432.

[0025] In this embodiment, as Figure 5As shown, a lock hole rod 60 is provided inside the placement cavity of the cabinet 10, and each lock hole 61 is formed in the lock hole rod 60. Specifically, since the lock holes 61 are formed in the lock hole rod 60, it is not necessary to make holes on the inner surface of the cabinet 10, thereby increasing the rigidity of the cabinet 10.

[0026] In one embodiment, such as Figure 4 As shown, a support frame 50 is provided on the inner surface of the cabinet door 20, and multiple locking tongues 52 pass through the support frame 50 and are arranged at equal intervals vertically. Specifically, the movable plate 40 drives multiple locking tongues 52 simultaneously through the support frame 50, and because the multiple locking tongues 52 are arranged at equal intervals vertically, the uniformity of the seal can be improved.

[0027] In one embodiment, such as Figure 1 and Figure 5 As shown, a soft padding layer 12 is provided on the side of the cabinet body 10 near the cabinet door 20. Specifically, the soft padding layer 12 is made of rubber. Rubber has a certain elasticity and can absorb the impact force when the cabinet door 20 is closed, thereby reducing the collision and friction when the cabinet door 20 comes into contact with the cabinet body 10, and preventing the surfaces of the cabinet body 10 and the cabinet door 20 from being scratched or damaged.
