Description

Lock

The invention relates to a lock, especially a lock that can be applied to door frames of different thicknesses.

Existing locks, such as German Patent No. 20212010386 or German Patent No. 19839043, are mainly provided with a lock tongue that can move telescopically relative to the housing in a housing, and a handle linked with a handle is provided in the housing The linkage mechanism is provided with a lock tongue linkage mechanism which can be driven by a lock core structure to drive the lock tongue to telescopically move between a locking position and an unlock position relative to the casing. It can still rotate freely when it is in the lock position. When the lock tongue is in the lock position, the linkage mechanism of the lock tongue and the linkage mechanism of the handle are in a state of disengagement from each other. Therefore, the lock tongue will protrude outward relative to the housing when it is in the lock position When the locking tongue is in the unlocked position, it is pulled back relative to the housing and retracted into the interior of the housing, and is combined with the handle linkage mechanism.

However, because the lock tongue of the existing lock has moved from the unlocked position to the locked position, the lock tongue will protrude outward from the housing for a distance, so that a deeper locking system needs to be provided on the door frame relative to the lock tongue Groove for the lock tongue to extend into it, but the door frame with a thinner thickness often cannot be provided with a deeper locking groove, or the existing locking groove of the door frame needs to be digged again to match the movement of the locking tongue, so it is used. There are many restrictions and inconveniences.

Therefore, in view of the inconvenience and limitations of the existing lock structure and use, the present inventor has developed a present invention that can improve the existing deficiencies after continuous experimentation and research.

The main object of the present invention is to provide a lock which can keep the lock tongue from protruding relatively out of the housing when the lock tongue is moved from the unlocked position to the lock position, so that the lock can be matched with a thin door frame, and It is not necessary to deepen the lock groove on the door frame, but can improve the practicality and convenience of the lock.

In order to achieve the above object, the present invention mainly provides a lock, which includes: a housing; a locking tongue that is telescopically movable inside the housing and can protrude outside the housing; and one is fixedly connected to the locking tongue, and A lock tongue seat movable relative to the housing; a linking member is movably disposed in the housing, and is connected with the lock tongue seat, and forms a relative displacement with the lock tongue seat, wherein, between the link member and the lock tongue seat One of them is provided with a moving groove which can make the linking member move relative to the bolt base, wherein the linking member comprises a pivoting member and a sliding member, the pivoting member is pivotally connected to the bolting base, the sliding member It is a sliding mechanism that is relatively slidably connected to the pivoting member; and a locking mechanism that is provided on the housing and can abut against the linking member to position the lock tongue seat and the lock tongue at the locking position.

By the above-mentioned technical means, when the locking tongue of the present invention moves from the unlocking position toward the locking position, the locking tongue can be kept in the original position without moving relative to the housing, so the lock of the present invention can be applied to The structure of the door frame is thin or the lock groove on the door frame is shallow, and there is no need to dig deeper the lock groove, which can improve the use flexibility and convenience of the lock of the present invention.
