Lock catch structure and wrist watch employing same

Abstract

The invention relates to a lock catch structure and a wrist watch employing the same. The lock catch structure comprises a belt body and a lock catch; the belt has a first tooth-shaped structure; the lock catch comprises a pedestal, a cover body forming an accommodation space together with the pedestal, a second tooth-shaped structure disposed in the accommodation space and connected with the pedestal via an elastic piece and movable between a first position and a second position relative to the pedestal under the effect of the elastic piece, and a control button arranged in the opening of the cover body in a limit movement way and abutting against at least one side of the second tooth-shaped structure; and the control button enables the second tooth-shaped structure to move from the first position to the second position. When the second tooth-shaped structure is at the first position, the first tooth-shaped structure and the second tooth-shaped structure are clamped mutually, and the belt body is fixedly disposed in the lock catch; and when the second tooth-shaped structure is at the second position, the first tooth-shaped structure is divorced from the second tooth-shaped structure, and the belt body is movable relative to the lock catch.

Description

technical field [0001] The invention relates to a buckle structure, in particular to a buckle structure which utilizes a toothed structure inside the buckle and an elastic member to adjust the length of a belt body.
