Abstract

A lock for controlling a normal open state or a normal close state by using a key comprises a lockset panel, a handle, a lock bolt and a lock cylinder. A shifting fork is sleeved on the lock cylinder, and a sliding block is arranged above the lock cylinder. A clutch assembly is installed above the sliding block and is composed of an idle sleeve cover, an idle sleeve and an idle body, locking holes are arranged on lateral faces of both the idle sleeve and the idle body, the handle is connected with an end port of the idle body, and the end port of the idle sleeve cover is fixedly connected with a square bar. A thimble is arranged between the clutch assembly and the sliding block. The lock controls the clutch assembly to open and close through the key to control the handle which directly drives the lock bolt to move, and the key does not drive a lock body mechanism and the lock bolt directly, so that stress of the key is small, and bending or breaking is not easy to cause. The design of idle of the handle can avoid damage to the lock body during forced pressing and forced twisting of outer force. A method that normal open and normal close of the lock on a door are arranged is ingenious and convenient, so that the lock is particularly suitable to use in office spaces where personnel frequently pass in and out a room.

Description

Control with key and often to open or the lock of normally off

Technical field

The present invention relates to a kind of control with key often opens or the lock of normally off.

Background technology

In the existing lockset, key is directly to control dead bolt by lock body mechanism to be used for opening the door or closing the door, in the use procedure, key need to be inserted in the lock core hole, firmly revolve and turn around or two circles, reach the purpose of opening the door or closing the door, whole process since key to bear strength larger, for preventing key distortion or fracture, the design of key is often durable thick.

Summary of the invention

Purpose of the present invention just provides a kind of simple in structure, futuramic control with key and often opens or the lock of normally off.

Of the present invention control with key often opened or the lock of normally off, comprise lock body mechanism, panel of lock, handle, dead bolt, lock core, be characterized in, shift fork is nested with on lock core, affixed with lock core, the top of lock core is provided with slide block, and slide block is fixed on the panel of lock by bearing pin, and slide block can slide up and down along bearing pin; Clutch assembly is installed in the top of slide block, clutch assembly is by the idle running upper shield, idle running cover and idle running body form, the idle running upper shield, idle running cover and idle running body are the circular body of hollow, the idle running body is placed in the idle running cover and is fixed by the idle running upper shield, the idle running body can rotate in the idle running cover, the idle running cover is connected by screw with the idle running upper shield, the idle running cover all has lock hole with the side of idle running body, the axle of two lock holes is on same cross section, handle links to each other with an openend port of idle running body, one openend port and the square bar of idle running upper shield are affixed, and the other end of square bar is connected with lock body mechanism, and the rotation of square bar is stretched out and contraction by lock body mechanism control dead bolt; Be provided with thimble between clutch assembly and the slide block, the lower end of thimble and slide block top movable contact, the upper end of thimble and the idle running of clutch assembly cover contacts side surfaces.

Of the present invention control with key often opened or the lock of normally off, operating principle is, key is inserted in the lock core hole, (direction as shown sees it is counterclockwise) rotates approximately 90 jiaos clockwise, shift fork is the same angle of rotating photo simultaneously, shift fork promotes to move on the slide block, and the drive thimble moves upward, thimble inserts in the lock hole of idle running cover and idle running body side surface simultaneously, and clutch assembly is snapped shares handle, the idle running cover, the idle running body, idle running upper shield and square bar interlock, the square bar that moves through of handle drives lock body mechanism and tongue linked, at this moment, for lock body is normally open, by the motion of handle control dead bolt; When key inserts in the lock core hole, (direction as shown sees it is clockwise) rotates approximately 90 jiaos counterclockwise, and shift fork is the same angle of rotating photo simultaneously, and shift fork can not promote to move on the slide block, thimble can't move, the idle running body can only dally in the idle running cover, and at this moment, handle rotating can only drive the motion of idle running body, clutch assembly is in the state of leaving, square bar is motionless, and dead bolt is in the state of stretching out, and also is that lock body is normally off.

Of the present invention control with key often opened or the lock of normally off, to control handle by the switching of key control clutch assembly, directly drive the dead bolt motion by handle again, realize that the unlatching of lock is with closed, because key not direct-drive lock body mechanism and dead bolt, therefore, key stressed very little, can design lightly, be not easy to occur bending or fracture; The design of handle idle running can prevent that external force from causing damage to lock body when turning round by force by force; Because this lock arranges door and often opens and the ingenious convenience of normally closed method, the personnel of being specially adapted to pass in and out the room and use the office space frequently.
