Abstract

The invention discloses a lever handle push-pull lock. A lever handle is pushed and pulled to realize locking and unlocking. A lock body is indirectly connected with the handle through eight lock body return springs; the handle is connected with a lock latch through a rod; the lock latch can be placed in a groove of a lock tongue; and the lock tongue has a symmetrical tongue shape structure and is connected with the lock body through one lock tongue return spring. When a door is closed, the handle is pushed or pulled so as to move the lock latch out of the groove of the lock tongue, tangential force of the outer wall of a lock hole on a door frame is applied to the lock tongue so that the lock tongue is retracted inward; when the handle is pushed continuously, the lock tongue crosses the outer wall of the lock hole on the door frame to reach the position of the lock hole on the door frame and is extended into the lock hole; and when a hand is loosened, the lock latch returns to the groove of the lock tongue and then the door is locked. When the door is opened, the handle is pulled to move the lock latch out of the groove on the lock tongue, tangential force of an inner wall of the lock hole on the door frame is applied to the lock tongue so that the lock tongue is retracted inward, the door continuously advances, the lock tongue crosses the inner wall of the lock hole on the door frame to reach the position out of the lock hole on the door frame and is extended outward, and the lock is unlocked. The novel lever handle push-pull lock can be used for dormitories, households and the like.

Description

The handle push-pull lock
Technical field
The present invention relates to door lock, especially a kind of handle push-pull lock.
Background technology
Hand holding lock is present indoor lockset commonly used, its good looking appearance and practical and convenient, hand holding lock is often installed oblique tongue and square tongue simultaneously in order to improve safety in lock body, general way is to control the action of oblique tongue with handle, and square tongue is to drive the rotation that is located at the lock core on the lock body by key to realize.Handle is normally controlled oblique tongue by the mode of twisting, but because of frequent use causes the internal construction fatigue damage easily, and needed strength is more big during more the turning on of number of times of twisting more, and the final problem that may occur twisting not open just can only be repaiied and be locked or reinstall.Hand holding lock is that left handle, right handle or two-way handle all have numerous, the complex structure of part, and handle commutation is loaded down with trivial details, use inconvenience and cost of production height, makes the shortcoming that is difficult for.
Summary of the invention
The objective of the invention is to solve above-mentioned existing problems, a kind of novel handle push-pull lock easy to use, simple in structure, with low cost is provided.
The technical solution adopted for the present invention to solve the technical problems is: hand holding lock is turned on the mode of unblanking change the mode that the handle push-and-pull is unblanked into.
Invention comprises that mainly lock body, lock body back-moving spring, dead bolt, dead bolt back-moving spring, dead bolt upper groove, handle, lock bolt, connection handle and lock bolt are bar, dead bolt sliding tray, the metal sheet of one.
The dead bolt sliding tray is arranged on the dead bolt, and the dead bolt sliding tray is connected with the back of lock body; Dead bolt back-moving spring one end is connected the back of lock body, and the other end connects on the dead bolt root of the tongue, and dead bolt is had outside elastic force; Lock body is fixedlyed connected with eight lock body back-moving springs, and the other end of lock body back-moving spring connects one and metal sheet; Metal sheet and bar are one, and bar connects as one by perforate and handle on the face of the lock body left and right sides again; Handle is connected with bar by the perforate on the face of the lock body left and right sides, and there is a lock bolt with the cuboid of bar one below, top bar middle part; A groove is arranged on the dead bolt, and the lower end of cuboid lock bolt can be placed in the groove, and can shift out groove along the horizontal direction of inside and outside handle line; Dead bolt is the ligulate symmetric shape; When unclamping handle, because the effect of eight lock body back-moving springs that link to each other indirectly with handle, lock bolt just is placed in the groove of dead bolt, and dead bolt reaches outside the lock body; Push away or when pulling handle, lock bolt leaves the groove of dead bolt, dead bolt is subjected to the effect of tangential force, the withdrawal lock body; Realize unblanking to lock by holding the handle push-and-pull.
When grabbing handle, the people goes to close the door, when dead bolt is run into the outer wall of the lockhole on the doorframe, dead bolt is subjected to the tangential force of the lockhole outer wall on the doorframe, because lock bolt is put in the groove of dead bolt, dead bolt can't shrink inwards, continuing push handle shifts out lock bolt from the groove of dead bolt, this moment the dead bolt retractable, continue push handle again, dead bolt shrinks inwards owing to be subjected to the tangential force of the lockhole outer wall on the doorframe, door moves on, and the outer wall that dead bolt is crossed the lockhole on the doorframe arrives the position of the lockhole on the doorframe, and dead bolt is because to be subjected to the thrust of dead bolt back-moving spring protruding, dead bolt reaches in the lockhole on the doorframe, unclamp hand, eight lock body action of reset spring are got back in the groove of dead bolt in the lock bolt that is connected one with handle, lock.
When unblanking, the people is grabbing handle and is going to open the door, dead bolt is run into the inwall of the lockhole on the doorframe, because lock bolt is put in the groove of dead bolt, dead bolt can't shrink inwards, pulling on handle shifts out lock bolt from the groove of dead bolt, this moment, the dead bolt retractable pulled on handle again, and dead bolt shrinks inwards owing to be subjected to the tangential force of the lockhole inwall on the doorframe, door moves on, the inwall that dead bolt is crossed the lockhole on the doorframe arrives the outer position of lockhole on the doorframe, and dead bolt unclamps hand because to be subjected to the thrust of dead bolt back-moving spring protruding, eight lock body action of reset spring are got back in the groove of dead bolt in handle and the lock bolt that is connected one, unblank.
The invention has the beneficial effects as follows: at closing time, promoting handle drive lock bolt shifts out from the groove of dead bolt, dead bolt shrinks inwards owing to be subjected to the tangential force of the lockhole outer wall on the doorframe, door moves on, the outer wall that dead bolt is crossed the lockhole on the doorframe arrives the position of the lockhole on the doorframe and reaches in the lockhole, unclamp hand, lock bolt is got back in the groove of dead bolt, and door automatically locks.When opening the door, haul handle drive lock bolt and shift out from the groove of dead bolt, dead bolt shrinks inwards owing to be subjected to the tangential force of the lockhole inwall on the doorframe, and door moves on, the inwall that dead bolt is crossed the lockhole on the doorframe arrives the outer position of lockhole on the doorframe and protruding, and lock is opened automatically.No matter wind is much or how to go to other position of sliding door, all can not open door.Than common handle turn on the lock turn on unblank more to save time, laborsaving, convenient, simple, durable.
