Detailed Description

An embodiment of the mechanical lock with a lock cover according to the present invention will be described in further detail with reference to fig. 1 to 3.

A mechanical lock with a lock cover comprises a lock shell 1 and a lock cylinder 2, wherein the lock cylinder 2 is arranged in a lock hole 11 of the lock shell 1; the lock shell 1 is rotatably provided with a lock cover 4 covering the lock hole 11 through a rotating component 3, wherein the lock shell 1 is provided with a rotating hole 12 for mounting the rotating component 3;

the rotating assembly 3 comprises a rotating shaft 31 and a reset torsion spring 32, one end of the rotating shaft 31 is arranged in the rotating hole 12, and the other end of the rotating shaft 31 penetrates through the rotating hole 12 to be connected with the bottom surface of the lock cover 4; wherein the rotation hole 12 is connected to the edge of the bottom surface of the locking cap 4 such that the locking cap 4 is eccentrically rotated on the rotation shaft 31 when the rotation shaft 31 is rotated.

The reset torsion spring 32 is sleeved outside the rotating shaft 31, wherein one torsion bar of the reset torsion spring 32 abuts against the lock cover 4, and the other torsion bar abuts against the lock shell 1;

the lock shell 1 is rotatably provided with a lock cover 4 for covering the lock hole 11, when the lock is unlocked, the lock cover 4 is opened from the upper part of the lock hole 11 by rotating the lock cover 4, and a key is inserted into a key hole in the lock cylinder 2; after the lock is unlocked, the lock cover 4 is loosened; the lock cover 4 rotates in the opposite direction under the action of the reset torsion spring 32, and automatically covers the lock hole 11 again; the lock hole 11 of the mechanical lock and the key hole on the lock core 2 are always covered by the lock cover 4, so that dust and the like in the environment are prevented from entering the lock core 2 to block the key hole; better protects the mechanical lock and prolongs the service life of the mechanical lock.

One end of the rotating shaft 31 is provided with a limiting part 311, wherein at least one position of the distance between two points on the end surface of the limiting part 311 is larger than the aperture of the rotating hole 12, so that the limiting part 311 can be abutted against the hole wall of the rotating hole 12; thereby restraining one end of the rotation shaft 31 in the lock case 1 and preventing the lock cover 4 from falling off from the lock case 1.

The lock cover 4 is circular, and the diameter of the lock cover 4 is larger than that of the lock hole 11, so that the lock hole 11 can be better covered; the mechanical lock is better protected.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
