[0022] The following further explains the embodiments of the present utility model with reference to the accompanying drawings.

[0023] Embodiment:

[0024] As Figures 1 - 4 shown, an efficient locking device for an electric control cabinet door includes a fixed mounting plate 1 and a connecting limit block 2. Connecting support legs 3 are fixedly connected to both the top and bottom of the fixed mounting plate 1. A rotating mounting rod 4 is movably connected to the fixed mounting plate 1. One end of the rotating mounting rod 4 is provided with a first bolt 5. A connecting rotating block 6 is provided at one end of the rotating mounting rod 4 through the first bolt 5. The other end of the rotating mounting rod 4 is fixedly connected to a connecting locking mechanism 7. A connecting fastening mechanism 8 is provided on one side of the fixed mounting plate 1 close to the connecting locking mechanism 7. The connecting fastening mechanism 8 is electrically connected to an external control terminal, and the control terminal is fixedly connected to the surface of the electric control cabinet door.

[0025] The working principle of the above technical solution is as follows:

[0026] During the use process, the connecting support feet 3 are fixedly connected to the electric control cabinet door through threads, so that the rotating mounting rod 4 can pass through the inside of the electric control cabinet door and extend to the outside. Then, the connecting rotating block 6 is clamped with the rotating mounting rod 4 and fixedly connected through the first bolt 5. Then, the connecting limit block 2 is fixedly connected to the inner wall of the electric control cabinet through bolts. Then, the connecting rotating block 6 rotates the rotating mounting rod 4 and the connecting locking mechanism 7, so that the connecting locking mechanism 7 can be connected and matched with the first connecting mounting block 9, thereby quickly locking between the electric control cabinet and the electric control cabinet door, and the operation is convenient.

[0027] In another embodiment, as Figure 2 shown, the connecting limit block 2 includes a first connecting mounting block 9. One side of the first connecting mounting block 9 is fixedly connected with a connecting limit plate 10. A fixed limit through groove 11 is opened inside the connecting limit plate 10. The first connecting mounting block 9 is fixedly connected to the inner wall of the electric control cabinet through bolts.

[0028] It is convenient for the output end of the connecting locking mechanism 7 to stably insert into the inside of the fixed limit through groove 11 and be connected and matched with the connecting limit plate 10, so as to perform the locking process, and the operation is convenient.

[0029] In another embodiment, as Figure 2 shown, the connecting locking mechanism 7 includes a first movable mounting disc 12. The inner side of the first movable mounting disc 12 is symmetrically and movably connected with movable deflection limiting arms 13 through positioning axes. A guiding mechanism 14 is movably sleeved on the outer surface of the movable deflection limiting arms 13. A fixed through hole 15 is opened on the outer surface of the movable deflection limiting arm 13 located above.

[0030] When it is convenient to rotate the connecting rotating block 6 and the rotating mounting rod 4, the first movable mounting disc 12 can be driven to rotate, so that the movable deflection limiting arms 13 can be guided by the guiding mechanism 14, and the end portions of the movable deflection limiting arms 13 can be inserted into the inside of the fixed limit through groove 11 and be connected and matched with the connecting limit plate 10, so as to perform the locking process, and the operation is convenient.

[0031] In another embodiment, as Figure 2 shown, the connecting fastening mechanism 8 includes two second connecting mounting blocks 16. A second bolt 17 is provided between the second connecting mounting blocks 16 and the fixed mounting plate 1. A first connecting sleeve block 18 is fixedly connected between the two second connecting mounting blocks 16. An electric telescopic rod 19 is fixedly connected inside the first connecting sleeve block 18.

[0032] It is convenient for the output end of the electric telescopic rod 19 to insert into the inside of the fixed through hole 15, and further can limit the connection of the movable deflection limiting arms 13, and the operation is convenient.

[0033] In another embodiment, as Figure 2 shown, the output end of the electric telescopic rod 19 is slidably and fittingly engaged with the inner side of the fixed through hole 15.

[0034] This facilitates the stable insertion of the output end of the electric telescopic rod 19 into the inner side of the fixed through hole 15, and the operation is convenient.

[0035] In another embodiment, as Figure 2 shown, the outer surface of the movable deflection limiting arm 13 is slidably and fittingly engaged with the inner side of the fixed limiting through groove 11.

[0036] This facilitates the stable insertion of the end of the movable deflection limiting arm 13 into the inner side of the fixed limiting through groove 11, and the operation is convenient.

[0037] In another embodiment, as Figure 3 shown, the guiding mechanism 14 includes a guiding frame 20. A second connecting sleeve block 21 is provided on one side of the guiding frame 20 close to the fixed mounting plate 1. A second movable mounting disc 22 is movably connected to the inner side of the second connecting sleeve block 21. A fixed connecting rod 23 is fixedly connected to one side of the second movable mounting disc 22 close to the fixed mounting plate 1. One end of the fixed connecting rod 23 away from the second movable mounting disc 22 is fixedly connected to the fixed mounting plate 1.

[0038] This facilitates that during the movement and deflection of the movable deflection limiting arm 13, while the movable deflection limiting arm 13 moves inside the guiding frame 20, it drives the guiding frame 20 to deflect, and further drives the second connecting sleeve block 21 to rotate on the outer surface of the second movable mounting disc 22, so as to stably guide and limit the movable deflection limiting arm 13, and the operation is convenient.

[0039] Working principle of the utility model: During use, the first connection mounting block 9 is fixedly connected to the inner wall of the electric control cabinet through bolts. Then, the connecting support foot 3 is fixedly installed to the electric control cabinet door through bolts, and the control terminal electrically connected to the electric telescopic rod 19 is connected to the outer surface of the electric control cabinet door through bolts. Then, the electric control cabinet door is closed. Then, the connecting rotating block 6 is fixedly connected to the end of the rotating mounting rod 4 through the first bolt 5. Then, the connecting rotating block 6 is rotated, so that the rotating mounting rod 4 and the first movable mounting disc 12 rotate, enabling the movable deflection limiting arm 13 to deflect and stably move inside the guiding frame 20. During the deflection of the movable deflection limiting arm 13, it can drive the guiding frame 20 to deflect, thereby driving the second connecting sleeve block 21 to rotate on the outer surface of the second movable mounting disc 22, stably guiding and limiting the movable deflection limiting arm 13, so that the end of the movable deflection limiting arm 13 can be stably inserted into the inner side of the fixed limiting through groove 11 and connected to the connecting limiting plate 10 and the first connection mounting block 9, thereby locking the electric control cabinet door and the electric control cabinet. Finally, the control terminal can drive the electric telescopic rod 19, so that the output end of the electric telescopic rod 19 can be inserted into the inner side of the fixed through hole 15, thereby restricting and fixing the movable deflection limiting arm 13, and further enabling the movable deflection limiting arm 13 to be in a stable state, improving the locking stability, and the operation is convenient and fast.

[0040] The above embodiments only represent the specific implementation manners of the utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation on the patent scope of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the utility model.
