Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, the present invention provides an embodiment: a special locking device for a high-low voltage cabinet comprises a cabinet body 1 and a first cabinet door 3, wherein an upper lock cavity and a lower lock cavity are arranged in the cabinet body 1, a lock rod 15 is slidably mounted in the cabinet body 1, and the lock rod 15 penetrates through the two lock cavities; a sliding cavity is arranged in the cabinet body 1 at the top end of the lock rod 15 and is communicated with the upper locking cavity; the top of the lock rod 15 is inserted into the sliding cavity, and a second spring 16 is arranged above the lock rod 15. A locking button 8 is elastically arranged on the side surface of the first cabinet door 3, a connecting rod 13 extending into the upper locking cavity is arranged on one side of the locking button 8, an oblique angle lock head 14 is arranged at one end of the connecting rod 13, and the upper end of the oblique angle lock head 14 is arranged obliquely downwards; the lock rod 15 is provided with a lock groove 19 penetrating through the lock rod 15, and the upper end face of the lock groove 19 is obliquely and downwards arranged; an unlocking button 10 is also elastically arranged on the side surface of the first cabinet door 3, and an unlocking rod 18 extending into the lower locking cavity is arranged on one side of the unlocking button 10; the end of the lock release lever 18 and the bottom of the lock lever 15 are provided with inclined surfaces, and the inclined surface of the lock release lever 18 is in contact connection with the inclined surface of the lock lever 15.

When locking, the end of the bevel lock head 14 is a convex bevel, so that the bevel lock head can effectively be clamped on the side wall of the lock rod 15 after penetrating through the lock groove 19. When the lock is unlocked, the lock rod 15 moves upwards, the connecting rod 13 slides in the lock groove 19, when the oblique angle lock 14 completely falls into the lock groove 19, the lock button 8 is elastically installed on the first cabinet door 3, so the oblique angle lock 14 slides out of the lock groove 19 under the action of elastic force, and the lock rod 15 resets. And after the lock rod 15 is reset, the top of the port of the lock groove 19 close to the locking button 8 is positioned above the bevel lock head 14, so that the bevel lock head 14 can effectively penetrate through the lock groove 19 when the first cabinet door 3 needs to be locked.

Further, a first protective cover 9 is mounted on the front end face of the first cabinet door 3, and a first T-shaped sliding groove is formed in the first protective cover 9; the locking button 8 is T-shaped; the locking button 8 is slidably arranged in the first protective cover 9, and a connecting rod 13 positioned on the side surface of the locking button 8 penetrates through the first protective cover 9 and extends into the upper locking cavity; a first spring 12 is sleeved on the connecting rod 13 positioned in the first T-shaped sliding groove. The first spring 12 is in a compressed state when the first cabinet door 3 is locked.

Further, the bevel lock head 14 is provided as an integral structure with the link 13.

Further, a second protective cover 11 is mounted on the front end face of the first cabinet door 3, and a second T-shaped sliding groove is formed in the second protective cover 11; the unlocking button 10 is T-shaped; the unlocking button 10 is slidably arranged in the second shield 11, and an unlocking rod 18 positioned on the side surface of the unlocking button 10 penetrates through the second shield 11 and extends into the lower lock cavity; and a third spring 17 is sleeved on the unlocking rod 18 positioned in the second T-shaped sliding groove. The third spring 17 is in an extended state when the first door 3 is locked.

Further, install ampere meter 6 and voltmeter 7 on the preceding terminal surface of first cabinet door 3 respectively, and ampere meter 6 and voltmeter 7 all with first cabinet door 3 fixed connection, install second cabinet door 4 on the preceding terminal surface of the cabinet body 1, first cabinet door 3 and second cabinet door 4 all rotate with the cabinet body 1 through the hinge and are connected, install observation window 5 on the preceding terminal surface of second cabinet door 4, and observation window 5 and second cabinet door 4 fixed connection, base 2 is installed to the below of the cabinet body 1, and base 2 and cabinet body 1 fixed connection, install the locking means the same with first cabinet door 3 structure principle on the preceding terminal surface of second cabinet door 4 equally.

The working principle is as follows: during the use, when first cabinet door 3 needs to be opened, through pressing unlock button 10, unlock button 10 will extrude third spring 17 and promote unlock rod 18 to move to the inboard of the cabinet body 1, thereby make lock rod 15 shift up and extrude second spring 16, lock slot 19 of lock rod 15 will shift up with lock rod 15 this moment, thereby make oblique angle tapered end 14 and lock slot 19 break away from, and oblique angle tapered end 14 will pass lock slot 19 and move to the outside of the cabinet body 1 under the effort of first spring 12, it will make locking button 8 kick-back to be extruded first spring 12, thereby locking button 8 just can pass through connecting rod 13 pulling tapered end 14 and move to the outside of the cabinet body 1, thereby realize the effect of unblock, thereby just can open first cabinet door 3. When the first cabinet door 3 needs to be closed, the first cabinet door 3 is combined with the cabinet body 1, the locking button 8 is pressed down, the locking button 8 extrudes the first spring 12, meanwhile, the locking button 8 pushes the oblique angle lock head 14 to move towards the inner side of the cabinet body 1 through the connecting rod 13 and penetrates through the lock groove 19, because the upper end surface of the lock groove 19 is arranged obliquely downwards, and the upper end surface of the oblique angle lock head 14 is also arranged obliquely downwards, when the oblique angle lock head 14 penetrates through the lock groove 19, the oblique angle lock head 14 slides relative to the end surface of the lock groove 19, the locking rod 15 can be pushed to move upwards, the second spring 16 is extruded, after the oblique angle lock head 14 completely penetrates through the lock groove 19, the locking rod 15 falls down, the oblique angle lock head 14 is clamped at the back side of the locking rod 15, so that the oblique angle lock head 14 is.

The above is only the preferred embodiment of the present invention, and it should be noted that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which will not affect the utility model and the utility of the patent.
