Lock

Abstract

The invention discloses a lock. The lock comprises a side housing assembly, a panel connected to the opening side of the side housing assembly, a blocking block assembly mounted on the side housing assembly, a turning assembly arranged in the side housing assembly, and an operating assembly for driving the blocking lock assembly to shrink, wherein the blocking lock assembly comprises a guide rod which is movably arranged in the side housing assembly in a penetrating mode, an inclined tongue body connected to the guide rod, and a first elastic part for driving the guide rod to move towards theouter side of the panel; a through tongue hole corresponds to the inclined tongue body; the turning assembly comprises a blocking block connected to the guide rod, a reversing part arranged in the side housing assembly in a sliding mode and a second elastic part for returning the reversing part; and the reversing part is used for generating locking effect on the blocking block in the axial direction of the guide rod. After locking effect, on the blocking block, of the reversing part is relieved, the inclined tongue body is exposed to the outer side of the panel, and the direction of the tonguebody can be freely regulated, so that reversing of the inclined tongue body is accomplished, and universality of the lock is improved, and therefore, mounting errors or the goods return problem on direction of the inclined tongue body are avoided.

Description

technical field [0001] The invention relates to hardware products, in particular to a lock. Background technique [0002] At present, the locks installed on the casement doors and windows are usually composed of a lock body, a square tongue assembly on the lock body, a snap lock assembly and other auxiliary accessories, and the oblique bolt is directional, such as the left inner opening and the right inner opening. The oblique bolts of the locks for opening the door are in a symmetrical form, and the slopes on the two oblique bolts face different directions. If the oblique bolts cannot be reversed, the same lock cannot be matched with the left inner-opening casement door and the right inner-opening casement door respectively. Universal interchangeability, once the user buys the wrong lock, it will not be able to be installed and practical on the door and window, which increases the risk of merchants returning and exchanging goods, or prolongs the installation and delivery pe...
