Detailed Description

Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These exemplary embodiments are provided so that those skilled in the art can clearly understand the present invention and can implement the present invention according to the description herein. The drawings and detailed description are not intended to limit the invention, which is defined by the appended claims.

As shown in fig. 10 and 11, the locking device comprises a male buckle and a female buckle, wherein the male buckle is provided with a base, a lock catch and a spring, the lock catch is arranged in an oval shape and is installed on the base, the spring generates pretightening force to enable the base to be tightly combined with the lock catch, locking and unlocking are realized through rotation of the lock catch, the female buckle is provided with a bottom plate and a panel, lock holes through which the lock catch passes are formed in the bottom plate and the panel, and the lock holes are oval;

the male buckle is arranged on the luggage body and is fixed by sewing or riveting, the female buckle is arranged on the cover body and is fixed by adopting a barb and helical teeth,

the base is provided with a groove for limiting the lock catch to enable the lock catch to rotate to a fixed angle, and the groove is longitudinally and transversely arranged and is perpendicular to each other.

The lock catch is provided with a convex groove and is used for being matched with the groove of the base to enable the lock catch to rotate to a fixed angle, when the lock catch rotates to the vertical direction, the convex groove is meshed with the transverse groove of the base, and when the lock catch rotates to the horizontal direction, the convex groove is meshed with the longitudinal groove of the base.

The bottom plate is provided with a barb and is used for being connected with the panel, so that the trouble of fixing modes such as screws, vehicle lines and the like is eliminated.

The panel is provided with inclined teeth for matching with the panel barb, so that the bottom plate cannot be separated from the panel after being combined with the panel.

When the installation is carried out, corresponding holes are drilled on the cover body, and the bottom plate barb penetrates through the holes to be fastened with the panel.

When the lock is locked, the male buckle penetrates through the lock hole of the female buckle, the lock can be locked by rotating the lock catch by 90 degrees, and the lock can be unlocked by rotating the lock catch by 90 degrees again.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention.
