Description

Lock

The invention relates to an anti-theft device, in particular to a lock suitable for being installed on a door or a window.

The traditional locks directly extend the shackle of the shackle embedded in the door panel by the blade type key, so that the latch can be extended or retracted to achieve the purpose of locking or unlocking. However, because its mechanical components often cause disadvantages such as high failure rate and easy to be opened, it is gradually improved into a shackle with a lock.

However, since the length of such a lock head is fixed, in order to be applied to door panels of different thicknesses, different length specifications must be made correspondingly, resulting in an increase in stock preparation, manufacturing, and inventory cost. In addition, the lock can only be provided with a row of marbles, and has the disadvantage of poor security. In order to improve the anti-theft performance, reference may be made to a circular lock of an auxiliary lock (TW Publication No. M362275U1). However, since the lock core of the lock is directly coupled to a transmission rod for guiding the telescoping or retracting of the latch, and the angle of rotation is limited, it cannot be applied to the shackle of the multi-segment latch operation.

Therefore, the object of the present invention is to provide a lock that can easily adjust the length specification and improve the anti-theft property by providing an advantage of combining the aforementioned lock heads and removing the disadvantages.

Therefore, the novel lock is suitable for being mounted on a door panel and can be operated by a key. The door panel has an inner side and an outer side opposite the inner side. The lock comprises a lock unit, an internal control unit, and an external control unit.

The internal control unit is correspondingly disposed on the inner side surface and includes a linkage rod that is disposed and connected to the swaying member.

The external control unit is correspondingly disposed on the outer side surface, and includes a lock seat that is positioned relative to the door panel, a circular lock head mounted inside the lock seat, and a rotatably mounted inside the circular lock head The lock, and a clutch set installed inside the lock. The locker extends along an axis and has a locking hole, a mounting hole disposed on the opposite side of the locking hole along the axis, and a pair of slots recessed in the outer ring of the mounting hole. The linkage rod has a latching portion that extends into the mounting hole and has a non-circular cross section perpendicular to the axis. The clutch set is mounted in the mounting hole and has a blocking piece movable along the axis, at least one engaging piece that is pushed by the blocking piece and movable along the axis, and a occlusal piece mounted along the axis One side of the elastic piece that keeps the bite piece away from the linkage rod.
