FIG. 2 is a schematic diagram of the exploded structure of the present invention.

Detailed Description

The invention will be further described in detail with reference to the drawings and the detailed description below, in order to further understand the features and technical means of the invention and the specific objects and functions achieved.

As shown in fig. 1 and 2, the invention discloses a disc lock, which comprises an upper disc lock disc 1, a lower disc lock disc 2, a lock head 3 and a lock catch 4, wherein a steel nail 5 is fixed on the lower disc lock disc 2, the lock head is assembled on the steel nail and is fixedly connected with the lower disc lock disc through a rivet, the lock catch is arranged on the upper disc lock disc, a bulge 6 is arranged on the lower disc lock disc 2, and when the lock head is rotated to enable the lock head to be contacted with the bulge, the upper part of the lock head is buckled and assembled with the lock catch; when the lock head is rotated to make the lock head not contact with the bulge, the lock head is separated from the lock catch.

The bulges 6 are strip bulges arranged along the axial direction of the lower disc lock disc, and can be uniform strip bulges or local large and local small. In this embodiment, two parallel protrusions are provided, and the protrusions may be in a tapered or enlarged configuration from one end to the other.

In addition, the protrusions are of a unitary and one-piece construction. Or a segmented structure, in this embodiment, the protrusions are segmented structures.

The lock head 3 comprises a butterfly sheet 31, a spring sheet 32, a clamping sheet 33, a lock core 34, a base 36 and a hook sheet 35, wherein the base 36 is fastened on the lower disc lock plate 2 through rivets 7, steel nails 5 penetrate through the hook sheet 35, the lock core 34, the clamping sheet 33 and the butterfly sheet 31 and are locked through hexagonal nuts 37, the spring sheet 32 is arranged between the clamping sheet 33 and the butterfly sheet 31 and is respectively connected with the clamping sheet and the butterfly sheet in a mounting manner, the butterfly sheet is rotated to drive the hook sheet to synchronously rotate, the lower part of the hook sheet is contacted with the protrusions intermittently in the rotating process, and the upper part of the hook sheet is matched with the lock catch. The steel nails are used as the shafts, and the butterfly sheet can be rotated to drive the hook sheet to rotate.

A spring 38 is further arranged between the butterfly plate 31 and the base 36, one end of the spring 38 is fastened with the steel nail 5, and the other end of the spring is fastened on the surface of the butterfly plate 31, so that the butterfly plate has resilience after rotating. The spring is preferably the torsional spring, and the butterfly piece is when being in the positive central point position, and the spring is the natural state this moment, and when the butterfly piece was rotated to one side, the spring also received the extrusion, has the resilience, and resilience that can be more convenient improves the operation feel.
