Description

Lock body

Technical Field

The utility model relates to a lock body.

Background

The current common cabinet door lock or drawer lock is shown in figure 1: the lock mainly comprises a lock body 100' and a lock plate 200', wherein the lock plate 200' can lock or unlock a cabinet door, the lock body 100' comprises a lock shell 110', a lock cylinder 120' rotatably arranged in the lock shell 110' and a nut 130' sleeved on the lock shell 110', one end of the lock cylinder 120' extends out of the lock shell 110' to form a connector, the other end of the lock cylinder 120' is provided with a key inserting cavity, the lock plate 200' is sleeved on a connector of the lock cylinder 120', and the connector is provided with a screw 300' which can support the lock plate 200' on the outer end surface of the lock shell 100 '. During the use, with the lock dress on one of them in two cabinet doors, locking plate 200' is located the cabinet door inboard, and nut 130' supports on the outside of cabinet door, inserts the key and inserts the chamber rotation, and lock core 120' drives locking plate 200' and rotates, realizes the locking of cabinet door after locking plate 200' changes to another cabinet door inboard.

In order to avoid the excessive rotational displacement of the locking plate 200', the rotational angle of the locking plate 200' is limited. The lock plate 200' commonly used at present mainly has two types, such as one lock plate 200' shown in fig. 2, the surface of which is provided with a salient point 210', the salient point 210' slides in a gap by arranging the gap capable of accommodating the salient point on the outer end surface of the lock shell, so that the lock plate 200' rotates a certain angle; as shown in fig. 3, a lock plate 200 'has a flat surface, and other limiting structures are required to be disposed on the lock body to limit the rotation of the lock plate 200'. Two kinds of locking plates need to be matched with two kinds of lock bodies with different structures, the lock bodies cannot be used universally, and the adaptability is poor.
