Description
Technical field
The present invention relates to a kind of hardware lockset, especially a kind of latch bolt safe-guard door lock of energy axial lock.
Background technology
Door lock is that one is mounted on a door for door lock to be lived to the equipment to prevent other people from opening easily, the type of door lock
Very much, have mechanical, also there is electrical type, according to different use occasions and use demand, type differs, but most
Door lock should all have a common feature, that is, antitheft, such people make an issue of on antitheft to door lock, various each
The safe-guard door lock of sample emerges one after another, and in numerous safe-guard door locks, it is most commonly seen with mechanical safe-guard door lock.
Mechanical safe-guard door lock in a manner of unlocking manually based on, reasonable price, mechanical strength is higher, installation and repair
It is more convenient, therefore market occupancy volume is larger, this safe-guard door lock is mainly made of lock housing and the lock tongue in lock housing,
Wrench device is installed in lock housing and is connect with lock tongue, is provided with keyhole on wrench device, people by outside by key
It is inserted into keyhole and rotates the disengaging that wrench device can control lock tongue, when lock tongue stretches out lock housing, lock tongue, which enters, is mounted on door pocket
On dead bolt hole in and door lock lived, when lock tongue recedes into dead bolt hole, door can be opened freely, it can be seen that lock tongue is this kind of door
Important parts in lock, the quality and structure of lock tongue directly affect the quality of door lock, especially influence the antitheft of safe-guard door lock
Performance.This kind of safe-guard door lock is all to use door latch type lock tongue, and lock tongue can make when lock tongue is stretched out other than lock housing and is inserted into dead bolt hole
Safe-guard door lock moves radially, you can prevents door from being opened easily with wall.
Above-mentioned mechanical theftproof lock, there is following deficiencies：
1. lock tongue moves radially stroke, being controlled by lock tongue spring and wrench device, lock tongue is easy to be contracted in lock housing,
Phenomena such as leading to lock tongue clamping stagnation.
2. lock tongue cannot be limited and be locked in the axial direction, and the power applied to door lock when some stealers are to forcing open the door is rigid
It has been just axial force, if the anti-theft performance of antitheft door substantially reduces.
3. when outdoor is locked, need to be locked using key, it is inconvenient for use.
Invention content
In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to provide it is a kind of can to latch bolt radial direction
Shift motion is limited, and latch bolt axially carries out compression locking, and outdoor, which is not required to key, to lock, energy axial lock easy to use
Fixed latch bolt safe-guard door lock.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of latch bolt safe-guard door lock of energy axial lock, including panel, shell, buckle, key, latch bolt, latch bolt planker, lock
Tongue hook, wrench device, stroke and axially stop block and safety lock device；
The panel is fixedly connected with the casing, and lockhole, latch bolt planker, wrench device, stroke and axial direction are provided on buckle
Limiting device and safety lock device are built in shell；
One end of latch bolt is fixedly connected with the latch bolt planker in shell, and the other end of latch bolt is stretched out from middle panel, latch bolt
External part can be matched with the lockhole on buckle；
The bottom of latch bolt planker is provided with latch bolt spring, and the other end of latch bolt spring is fixedly connected with shell bottom wall；
Installation is there are two symmetrically arranged lock tongue hook on latch bolt planker, is respectively provided with that there are one hook bolts on each lock tongue hook；
The lock core and biography that wrench device includes knob spring, is sleeved on the knob of knob spring periphery, is built in knob spring center
Lock tongue hook of the knob spring respectively with latch bolt planker and on latch bolt planker is connected by movable plate, driver plate；Lock core and key phase
Matching；
When using key rotation lock core or twisting knob, driver plate can drive latch bolt and lock tongue hook to be passed in and out from lockhole；
When entering lockhole outside the latch bolt extending panel, lock tongue hook also with latch bolt extending panel outside, two hook bolts are located at the two of latch bolt
Side wall；When latch bolt is contracted in shell, two hook bolts are also contracted in shell and are closed with latch bolt and are accommodated on latch bolt planker；
Stroke and axially stop block include that stroke limit slot, limited block and limit torsional spring, stroke limit slot are arranged oblique
One end of the side of tongue drawing plate, limited block is located in stroke limit slot, and the other end and the limit torsional spring of limited block fit；
Safety lock device includes the sliding block being fixedly connected with latch bolt planker and is arranged the slide block in slider bottom；Sliding block
The other end be connected with lock core.
The sliding block is connected by sliding block spring with shell.
The bottom of the sliding block is provided with can stir row with the matched sliding groove of slide block, the sliding groove to slide block
Cheng Jinhang is limited.
The matching part of the slide block and sliding block is arc-shaped.
The panel is fixedly connected with shell by hexagonal countersunk head spline screw.
The present invention with the above structure, has the advantages that：
1. the setting of above-mentioned stroke limit slot and limited block can limit the stroke that moves radially of latch bolt, prevent from locking
The gouging abrasion of tongue clamping stagnation and lock tongue and buckle etc. is bad.
On the one hand 2. the setting of above-mentioned limit torsional spring can make the lockset of the application by the axial compression to limited block,
Coordinate more flexible, no clamping stagnation；In addition can be to being limited and being locked in latch bolt axial direction, the anti-theft performance of door greatly promotes.
3. the setting of above-mentioned safety lock device, in the outdoor handle that only need to be stirred slide block or be connected with slide block,
Latch bolt can be made further to extend, carry out backward hold, need not use key that could be locked, it is easy to use.
4. two symmetrically arranged lock tongue hooks, can be so that the axial lock clamp force of latch bolt both sides be balanced, locking ability is stronger, prevents
It is more preferable to steal effect.
