Abstract

The utility model relates to a lock driving device. A driving plate is arranged inside an outer lock body and lifted by a button; a meshing wheel is engaged on the inner side of the driving plate; an actuating wheel is arranged on the outer side of the meshing wheel and can lift the driving plate or rotate the meshing wheel by means of forward/reverse rotation; a rotating rod is fixedly embedded on the inner side of the meshing wheel; a driving shaft is arranged inside the rotating rod, passes through the meshing wheel and is connected with the actuating wheel; and the driving shaft passes through the lock latch and is bonded with a driving square hole of an inner lock body. Accordingly, by pressing the button or rotating the inner lock body forwardly or reversely, the lock latch can be unlocked to open the door; and the inner reset spring of the inner lock body is not linked when pressing the rotating rod to drive the lock latch to move, thereby preventing the problem that the door opening force is too large. Besides, the simple structure that the lock latch is driven to move with the use of one rotating rod can avoid the problem of the prior door lock that the length of the rotating rods on the two sides is required to be changed as the thickness of the door varies.

Description

The lock transmission device

Technical field

The utility model relates to a kind of device of lock, particularly relates to the excessive lock transmission device of strength that opens the door when a kind of energy life-saving avoids outside button to press simultaneously.

Background technology

The existing big grip handle lock structure that is provided with on door is to pass through gear or dwang of cam driven with outside button, passes lock bolt with dwang and directly is connected into the inboard lock body that is positioned at door.

By aforesaid structure design, when outside button is pressed, can drive the dwang rotation and separate the action that door bolt opens the door, also can drive the back-moving spring work of inboard lock body at the same time, but such design had both increased the power of opening the door of button, also make inboard back-moving spring frequent operation, reduced the application life of lock drive mechanism.

Also has big grip structure in another kind of early stage, it is the cam driven lock bolt motion of inserting lock bolt simultaneously by two dwangs of inside and outside both sides respectively, the structure that drives lock bolt work does not so respectively disturb mutually, but as long as thick the changing of door, for keeping inside and outside two dwangs can also be inserted in the cam of locking bolt simultaneously, will change the length of both sides dwang, the so shortcoming of installing inconvenience completely concerning the user.

The utility model content
