[0022] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are some, rather than all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it is not understood as a limitation to the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] As Figures 1-4 It is a schematic structural diagram of a low-voltage switchgear cabinet in a preferred embodiment of the present utility model. In this embodiment, a low-voltage switchgear cabinet includes a cabinet body 1. An installation cavity 2 is provided inside the cabinet body 1. A door body 3 is fixedly connected to the front end of the cabinet body 1 at the opening of the installation cavity 2 through a hinge. Insertion positions 22 are provided on the top and bottom surfaces at the opening of the installation cavity 2, and a locking port 21 is provided on one side surface of the opening of the installation cavity 2. An installation position 31 is provided on the surface of the door body 3. An interlocking device 4 is assembled in the installation position 31 and is movably connected to the insertion positions 22 and the locking port 21 through the interlocking device 4, thereby realizing the locking function between the door body 3 and the cabinet body 1 and effectively solving the problems proposed in the background technology.

[0025] In this embodiment, the interlocking device 4 includes an operating component 41, a rotating piece 42, and an insertion rod 43. The operating component 41 is fixedly connected to the rotating piece 42. Insertion rods 43 are connected above and below the surface of the rotating piece 42, so that during the rotation of the rotating piece 42, the function of driving the insertion rod 43 to move up and down is realized. A locking piece 44 is fixedly connected to one side of the surface of the rotating piece 42. The end of the insertion rod 43 away from the rotating piece 42 is inserted and connected to the insertion position 22, and the locking piece 44 is movably connected to the locking port 21. This structural design enhances the locking function between the door body 3 and the cabinet body 1.

[0026] In this embodiment, the operating component 41 includes an installation panel 411, an operating handle 413, and a connecting shaft 412. The installation panel 411 is fixedly installed in the installation position 31. A rotating position 414 is provided on the surface of the installation panel 411, and an operating handle 413 is rotatably connected in the rotating position 414. The operating handle 413 is connected to the connecting shaft 412, and the connecting shaft 412 is connected to the rotating piece 42. This structural design drives the rotating piece 42 to rotate by rotating the operating handle 413, and at the same time, the insertion rod 43 will rotate with the rotating piece 42 to realize the function of moving up and down.

[0027] In this embodiment, a first connection hole 421 is formed on the surface of the rotating piece 42. A connection block 45 is sleeved at one end of the insertion rod 43 close to the rotating piece 42. A second connection hole 451 is formed on the surface of the connection block 45. A fixing rod 46 is inserted and connected in the first connection hole 421 and the second connection hole 451 to realize the connection and fixation between the rotating piece 42 and the insertion rod 43.

[0028] In this embodiment, the end of the locking piece 44 away from the rotating piece 42 is arranged in an arc shape. This structural design avoids the situation that the locking piece 44 rotates in contact with the inner wall of the cabinet body 1 or the locking port 21 during the rotation of the rotating piece 42, resulting in the locking piece 44 being unable to cooperate with the locking port 21 to realize the locking between the door body 3 and the cabinet body 1.

[0029] Working principle

[0030] Specifically, the operator rotates the operating handle 413 to drive the rotating piece 42 to rotate. While the rotating piece 42 rotates, the locking piece 44 and the insertion rod 43 work synchronously, and the locking piece 44 cooperates with the locking port 21 and the insertion rod 43 cooperates with the insertion position 22.

[0031] The above content further elaborates on the present invention in combination with specific implementation manners. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope determined by the claims submitted for the present invention.
