Plane lock

Abstract

The invention relates to a plane lock. A base is installed on a door plate, an operation handle gets close to or away from the base with a rotating shaft as a fulcrum, then a rotary knob originally needing to be rotated is changed into the operation handle which is pushed and pulled up and down, use is more convenient, when the operation handle is attached to the base, the operation handle is fixed by a locking mechanism and cannot be away from the base, and a locking effect is achieved; after the locking state is released, the operation handle is pulled upwards, the operation handle pulls a linkage handle to be opened with the rotating shaft as the fulcrum, a transmission block is linked to move upwards along a sliding groove, after a transmission rod connected with the transmission block moves axially, a lock pin on the transmission rod is separated from a lock catch on a door and window frame, and the opening function of a cabinet door is achieved; and transmission of the whole transmission block is achieved by pulling the linkage rod through the operation handle, original gear and rack transmission is replaced, the problems of tooth disengagement, tooth sliding, tooth breakage and the like are solved in the using process of the plane lock, transmission is more stable, larger loads can be borne, and the plane lock is suitable for large-specification cabinet doors.

Description

technical field [0001] The invention relates to the field of locks, in particular to a plane lock. Background technique [0002] Plane lock refers to the opening and closing anti-theft tool set on doors, boxes, drawers and other objects. It needs a special key to open. There are many kinds of lock products in today's society with different functions. Some of them are used in some cabinet doors. Such locks should not only prevent others from opening and closing at will, but also make it convenient for users to open and close. Some cabinet doors and plane locks are provided with transmission rods at both axial ends, and the locking nails on the transmission rods on the drive plane locks are sent into or Breaking away from the lock on the door and window frame, the locking or opening function of the door and window is realized, but the existing plane lock has the following disadvantages when driving the transmission rod: First, the driving handle adopts a knob, which is not con...
