Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-2, an automatic locking device for a rear cabinet door of a low-voltage switch cabinet comprises a guide box 1, wherein a plurality of mounting holes 8 are formed in the guide box 1, and the guide box 1 is mounted at the bottom of the rear cabinet door through the mounting holes 8 by using bolts.
Be equipped with the locking plate 2 that can reciprocate on direction box 1, locking plate 2 upper end is equipped with and cooperates the spacer pin 3 that is used for restricting locking plate 2 to move down with direction box 1, and locking plate 2 lower extreme is equipped with tapered end 4, is equipped with on locking plate 2 to cooperate with direction box 1 to be used for carrying out the reset spring 5 that resets to locking plate 2. The locking plate 2 is driven by external force to move upwards to separate the lock 4 from the bottom of the door frame of the rear cabinet door, so that unlocking is realized; external force is removed, the locking plate 2 automatically moves downwards under the action of the reset spring 5, the lock head 4 is enabled to be propped against the bottom of the door frame of the rear cabinet door again, locking is achieved, the limiting pin 3 can prevent the locking plate 2 from moving downwards excessively, and the lock head 4 is prevented from being damaged due to violent collision with the bottom of the cabinet body of the switch cabinet.
Above-mentioned locking plate 2 is located in direction box 1, and the locking plate 2 upper end passes and connects in spacer pin 3 behind direction box 1 top, and the locking plate 2 lower extreme passes and connects in tapered end 4 behind direction box 1 bottom. Specifically, as shown in fig. 2, the limit pin 3 penetrates and is fixed on the lock plate 2 along a direction perpendicular to the lock plate 2, and two ends of the limit pin 3 abut against the outer wall of the top of the guide box 1. As shown in fig. 1, the locking plate 2 and the locking head 4 are integrally formed, the locking head 4 includes a limiting portion 41 formed by bending the lower end of the locking plate 2 to the front side of the guiding box 1 and a locking portion 42 formed by bending the end of the locking plate 2 away from the limiting portion 41, and the limiting portion 41 can abut against the bottom of the guiding box 1 after moving upwards.
For realizing reset spring 5's function, as shown in fig. 1, set up bar opening 6 at 2 middle parts of locking plate along 2 moving direction of locking plate, bar opening 6 top is passed through pole setting 7 and is connected with 6 bottoms of bar opening, pole setting 7 and 2 integrated into one piece of locking plate, and reset spring 5 cover is established on pole setting 7, and 5 both ends of reset spring offset with 1 top inner wall of direction box and 1 bottom inner wall of direction box respectively. Therefore, when unlocking is carried out, the locking plate 2 is driven to move upwards by external force, the spring is compressed, and after the locking plate moves to the position where the limiting part 41 abuts against the bottom of the guide box 1, the locking part 42 can be separated from the bottom of the door frame of the rear cabinet door, so that unlocking is carried out; after the external force is cancelled, the locking plate 2 is reset under the action of the restoring force of the spring, and the locking part 42 is abutted against the bottom of the door frame of the rear cabinet door, so that the locking is completed.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
