Lock

Abstract

The present invention relates to a lock which comprises a locking device such as hoop, clamp or similar components and a bolt. The said bolt moves between a locking position and an unlocking position, the said bolt locks the said locking device at the said locking position, the said locking device is unlocked at the unlocking position, and the bolt is pressed in the direction of locking position.Furthermore, the lock has a blocking device, recurring to it, the bolt can be blocked at the locking position, so as to avoid the movement in the direction of the unlocking position. Moreover, the said lock also has a rotating device which can be operated rotatablely. The rotating device that works together with blocking device or bolt has two control sections, in order to move the said blocking device to unlocking position based on the rotatable operation of the rotating device and move the bolt to the unlocking position against the press.

Description

Technical field [0001] The invention relates to a lock with a locking device such as a lock bow, a clamp or the like, and a lock tongue. The lock tongue is movable between an upper lock tongue position and an unlocking tongue position, and the lock tongue is at the upper lock tongue position The locking device is locked, and the locking device is unlocked in the unlocking tongue position, wherein the locking tongue is biased in the locking position. Background technique [0002] The advantage of such a lock with a biased tongue is that the locking device will be automatically locked by the tongue in a predetermined position, that is, it can be locked to prevent unauthorized or accidental movement. In order to improve the comfort of operation, automatic functions can also be realized. In this way, the user only needs to install the lock bow into the lock body so that the lock bow can be locked, without special operation of the lock cylinder or similar components for this purpose....

AI Technical Summary

Problems solved by technology

[0003] The shortcoming of this kind of lock with biased dead bolt is that when the lock body is subjected to instantaneous force, the dead bolt will move relative to the lock body against its bias due to its own inertial force, thereby causing the locking device to unlock the dead bolt instantaneously (i.e. by the so-called hammering)
