Detailed Description
The invention will be further described with reference to examples of embodiments in the accompanying drawings, in which:
the lower end face of the cover plate 1 refers to an end face facing the electronic case, and the upper end face of the cover plate 1 refers to an end face facing away from the electronic case.
As shown in fig. 1 to 4, the invention mainly comprises a cover plate 1, wherein a boss 2 is arranged on the lower end surface of the cover plate 1, and the lower end surface of the boss 2 is connected with a cover box 3 through a screw. The cover box 3 is equipped with sliding chamber 9 towards boss 2 one side, is equipped with opening and closing plate 4 in the sliding chamber 9, and opening and closing plate 4 can slide along sliding chamber 9 left and right sides.
At least one lock tongue 8 is arranged on one side of the opening plate 4, and a locking through hole 11 is arranged at the position of the cover box 3 facing the lock tongue. At least one spring 6 is arranged on the other side of the opening plate 4, the front end and the rear end of the spring 6 are respectively pressed and contacted with the sides of the opening plate 4 and the sliding cavity 9, and the spring 6 pushes the lock tongue 8 to extend out of the locking through hole 11.
The spring 6 is sleeved on the guide rod 7, one end of the guide rod 7 is fixed on the opening plate 4, and the other end of the guide rod passes through the sliding cavity 9 and stretches into the guide cavity 10 arranged in the cover box 3.
The upper end face of the lock tongue 8 is a flat surface, and the lower end face is an inclined plane. When the electronic case is used, the locking groove 15 matched with the locking tongue 8 is formed in the electronic case, the inclined surface of the locking tongue 8 can smoothly pass through the covering step 16 above the locking groove 15 when being pressed down, and the flat surface of the locking tongue 8 can ensure that the locking tongue 8 cannot fall out of the locking groove 15 after entering the locking groove.
The upper end face of the cover plate 1 is provided with an opening and closing switch 5, and the opening and closing switch 5 penetrates through the cover plate 1 and is connected to the opening and closing plate 4 through screws. The cover plate 1 is provided with a strip-shaped opening and closing hole 12 connected with the opening and closing switch 5, and the opening and closing switch 5 can move left and right along the opening and closing hole 12, so that the opening and closing plate 4 is driven to slide left and right along the sliding cavity 9.
At least one supporting lug 13 is arranged on one side of the cover plate 1, the supporting lug 13 is rotationally connected with a supporting plate 14 through a pin shaft, and the supporting plate 14 is connected to the electronic case.
The working principle of the invention is as follows: when the cover plate rotates to the closing position, the cover plate is pressed hard, the electronic case main body cover step props against the inclined plane of the lower end of the lock tongue, and a transverse force is generated on the inclined plane of the lower end of the lock tongue under the action of external force to force the lock tongue to move backwards. When the lock tongue moves backwards, the lock tongue passes through the cover step of the case body, and the cover plate is closed in place. The spring bolt moves forward under the action of the restoring force of the spring and enters the locking groove under the cover step of the case body to finish the closing action. When the cover plate is opened, the opening and closing switch is transversely shifted to drive the lock tongue to move backwards to withdraw from the locking slot of the case main body and simultaneously pass through the covering step of the case main body, and the cover plate rotates outwards to finish the opening action.
The electronic case locking device is simple, compact and reasonable in structure, stable and reliable in locking, capable of conveniently and rapidly locking and unlocking the electronic case, and capable of improving operation efficiency.
