Lock

Abstract

The invention discloses a lock, which comprises a lock body, a spring bolt and a rolling part, wherein the lock body is provided with a spring bolt penetrating hole and a mounting groove; the mounting groove is communicated with the spring bolt penetrating hole; the spring bolt is telescopically inserted into or separated from the spring bolt penetrating hole; the rolling part is mounted in the mounting groove; a part of the rolling part extends into the spring bolt penetrating hole; and the rolling part is in rolling contact with the spring bolt. According to the lock provided by the technical scheme, the problems that the unlocking and locking processes of an existing lock are strenuous, and the user experience is poor can be solved.

Description

technical field [0001] The invention relates to the technical field of security products, in particular to a lock. Background technique [0002] Locks are an important security product in people's production and life, which can provide users with stable and reliable security protection. The lock is usually locked by means of the locking tongue and the locking hole to limit each other, and the unlocking is completed by retracting the locking tongue. Structures such as a lock body and a gusset are arranged outside the lock tongue. During the process of the lock tongue expanding and contracting relative to the lock body, the contact area between the outer surface of the lock tongue and the structure such as the lock body is relatively large, resulting in a gap between the lock tongue and the lock body. The frictional force between such structures is relatively large, and after long-term use, the lock tongue will be worn out, the safety of the lockset will be reduced, and the p...
