Problems solved by technology

For some single-function window locks, such as a cam lock installed between two windows, as long as the cam lock disc shaft in the cam lock is connected to the frame of one window, the catch in the cam lock is fixedly arranged on the other side. On the corresponding frame of the window, turn the cam lock disc to slide into the lock, and then the window can be locked. Although the structure of this cam lock is relatively simple, because the cam lock disc is relatively easy to rotate, it can be locked between two windows. When there is a gap, the cam lock is easier to be picked open, and the security is not good

Abstract

The invention discloses a crescent lock, which comprises a base and a cam lock disk matched with a lock catch fixed and arranged on a window frame. An axle seat is integrally arranged on the base, and the cam lock disk is coupled on the axle seat. The invention is characterized in that an elastic positioning device is arranged between the cam lock disk and the base; the invention has the advantages that the structure is simple, the cost is low, because the elastic positioning device is arranged between the cam lock disk and the base, and the relative rotation between the cam lock disk and the base requires a certain external force, when the window is closed, even through a gap exists between two window casements, the window lock is uneasily to be picked; a lock disk locking mechanism is additionally arranged between the cam lock disk and the base, the cam lock disk is locked on the base through a lock core and a dead bolt, and the mutual rotation between the cam lock disk and the base can not happen, thereby greatly increasing the safety and the insurance of the window lock.

Description

technical field [0001] The invention relates to a lock, in particular to a crescent lock. Background technique [0002] Window is an integral part requisite in house construction, and for anti-theft, people have installed window lock on window, and for this reason, various window locks are full of beautiful things in the market at present.
