Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0027] As Figures 1-3 shown, the present application provides an interlocking mechanism for a cabinet body, including an equipment cabinet 1. At the same time, a cabinet door (not shown in the figure) for closing the equipment cabinet 1 is hinged on the equipment cabinet 1. At the same time, a locking assembly 2 is provided on the equipment cabinet 1. The locking assembly 2 is used to lock the cabinet door and the equipment cabinet 1. At the same time, a limiting assembly 4 is provided on the locking assembly 2. The limiting assembly 4 is used to limit the locking assembly 2. At the same time, a rebound assembly 3 is provided on the equipment cabinet 1. The rebound assembly 3 is used to rebound the cabinet door and the equipment cabinet 1 when they are hinged. Specifically:

[0028] As Figures 3-4 shown, the locking assembly 2 includes a lock frame 24 fixedly installed on the cabinet door. At the same time, a screw 21 is rotatably installed inside the lock frame 24. At the same time, two groups of nuts 22 are threadedly installed on the screw 21. At the same time, a lock tongue 23 is slidably arranged on the screw 21, and the lock tongue 23 is located between the two groups of nuts 22, so as to fix the lock tongue 23 by the two groups of nuts 22. At the same time, the position of the nut 22 on the screw 21 can be adjusted to synchronously adjust the position of the lock tongue 23 to be applicable to equipment cabinets 1 of different sizes, and the cabinet door is locked by the lock tongue 23 against the inner wall of the equipment cabinet 1;

[0029] As Figures 3-4As shown, the limiting component 4 includes a groove 46 formed in the lock frame 24. Meanwhile, a handle 43 is movably arranged inside the groove 46. A lock core 41 is rotatably installed inside the handle 43. A latch 42 is fixedly installed on the lock core 41. A cavity 47 adapted to the latch 42 is formed inside the handle 43 to facilitate the rotation of the latch 42. A card slot (not shown in the figure) adapted to the latch 42 is formed inside the lock frame 24 to facilitate the fixation of the latch 42, thereby synchronously fixing the handle 43;

[0030] Meanwhile, a rotating part 44 is fixedly installed on the handle 43. The rotating part 44 is an existing rotary damper, and its specific structure and principle will not be elaborated here. A rotating rod 45 is rotatably installed on the screw rod 21, the handle 43 and the rotating part 44 together;

[0031] In the initial state, the cabinet door and the equipment cabinet 1 are in a hinge state. The handle 43 is located inside the groove 46, and the latch 42 on the lock core 41 is located in the cavity 47 and the card slot to fix the handle 43. When the cabinet door needs to be opened, insert the key into the lock core 41 and rotate it, driving the part of the latch 42 located in the card slot to separate from the card slot and rotate the part located in the card slot into the cavity 47 to release the fixation of the handle 43. Then flip the handle 43. The handle 43 can be flipped along the axis direction of the rotating rod 45. Due to the effect of the rotating part 44, the handle 43 can be fixed in the flipped position;

[0032] Rotate the handle 43, driving the lock tongue 23 in the locking component 2 to rotate along the axis direction of the screw rod 21. The lock tongue 23 separates from the inner wall of the equipment cabinet 1, thereby completing the unlocking of the equipment cabinet 1 and the cabinet door. Through the multi-step unlocking process, the alertness of users and management personnel is improved. When the staff finds that multiple steps are required to unlock, they are more likely to realize the possible security risks and take corresponding preventive measures. At the same time, it can also prevent unauthorized personnel from using tools to pry open the lock tongue 23;

[0033] As Figure 2 and Figure 5 shown, the rebounding component 3 includes a mounting block 32 fixedly installed on the cabinet door. A fixing block 34 is fixedly installed on the equipment cabinet 1. A cylinder 35 is fixedly installed on the fixing block 34. A circular groove is formed inside the cylinder 35. A connecting rod 31 is rotatably installed inside the circular groove. A volute spring 33 is arranged on the connecting rod 31, and the other end of the volute spring 33 is arranged on the inner wall of the circular groove. The end of the connecting rod 31 far away from the cylinder 35 is rotatably installed on the mounting block 32;

[0034] When closing the cabinet door, the cabinet door drives the mounting block 32 to rotate, thereby driving the connecting rod 31 to rotate on the cylinder 35. At this time, the scroll spring 33 is tightened. Subsequently, the staff can lock the cabinet door through the locking assembly 2 and the limiting assembly 4. If the staff sometimes forgets to lock the cabinet door, the scroll spring 33 resets, thereby driving the connecting rod 31 to rotate, thereby driving the mounting block 32 to rotate, synchronously driving the cabinet door to rotate and separate from the equipment cabinet 1. So when the staff finishes maintenance and inspection and closes the cabinet door but forgets to lock the cabinet door through the locking assembly 2 and the limiting assembly 4, the cabinet door and the equipment cabinet 1 will be immediately separated, reminding the staff to lock the cabinet door and the equipment cabinet 1;

[0035] In summary, when the electrical cabinet needs to be maintained and inspected, unlock the locking of the limiting assembly 4, and then drive the locking assembly 2 to release the locking of the cabinet door through the limiting assembly 4, so as to facilitate opening the cabinet door. Through multi-step unlocking, the vigilance of the staff is improved. At the same time, when the staff forgets to lock the cabinet door, the rebounding assembly 3 separates the cabinet door and the equipment cabinet 1, reminding the staff to lock it.

[0036] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
