Description
Technical field
The present invention relates to a kind of hardware lockset, particularly a kind of side's tongue safe-guard door lock.
Background technology
Door lock is a kind of equipment for being mounted in and being used on door by door lock firmly to prevent other people from opening easily, the species of door lock
A lot, have mechanical, also there is electrical type, according to different use occasions and use demand, its species differs, but it is most
Door lock should all possess one it is common the characteristics of, that is, antitheft, such people are locked on antitheft on the door to make an issue of, various each
The safe-guard door lock of sample emerges in an endless stream, and in numerous safe-guard door locks, most commonly seen with mechanical safe-guard door lock.
Mechanical safe-guard door lock is based on unlocking mode manually, and its reasonable price, mechanical strength is higher, installs and repairs
It is more convenient, therefore market share amount is larger, the main dead bolt by lock housing and in lock housing of this safe-guard door lock is constituted,
Wrench device is installed in lock housing and is connected with dead bolt, keyhole is provided with wrench device, people by outside by key
Insertion keyhole simultaneously rotates the turnover that wrench device can control dead bolt, when dead bolt stretches out lock housing, and dead bolt, which enters, is arranged on door pocket
On dead bolt hole in and door lock is lived, when dead bolt is receded into dead bolt hole, door can be opened freely, it can be seen that dead bolt is this kind of door
Important parts in lock, the quality and structure of dead bolt directly affect the quality of door lock, particularly influence the antitheft of safe-guard door lock
Performance.This kind of safe-guard door lock is all to use door latch type dead bolt, and dead bolt can make when dead bolt stretches out beyond lock housing and inserted in dead bolt hole
Safe-guard door lock is moved radially, you can prevent door from being opened easily with wall.
Above-mentioned mechanical theftproof lock, has following deficiency：
1. dead bolt moves radially stroke, it is controlled by dead bolt spring and wrench device, dead bolt is easily contracted in lock housing,
Cause the phenomenons such as dead bolt clamping stagnation.
2. dead bolt can not carry out in the axial direction it is spacing with locking, and some stealers to forcing open the door when to door lock apply power it is firm
It has been just axial force, if the theftproof performance of antitheft door is substantially reduced.
3. it is inconvenient for use in outdoor locked, it is necessary to could be locked using key.
The content of the invention
In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a kind of energy other side tongue radially
Shift motion carries out spacing, square tongue axially progress compression locking, and outdoor, which is not required to key, to lock, and square tongue easy to use is antitheft
Door lock.
A kind of side's tongue safe-guard door lock, including panel, housing, button box, key, square tongue, square tongue drawing plate, wrench device, stroke
And axially stop block and safety lock device；
The panel is fixedly connected with the casing, square tongue drawing plate, wrench device, stroke and axially stop block and safety lock
Device is built in housing；
Side's tongue side of being built-in with tongue strong magnet；
It is provided with button box in lockhole, lockhole and is provided with button box magnet；
One end of square tongue is fixedly connected with the square tongue drawing plate in housing, and the other end of square tongue stretches out from middle panel, square tongue
External part can be engaged with the lockhole on button box；
The bottom side of the being provided with tongue of square tongue drawing plate, the other end of square tongue is fixedly connected with shell bottom wall；
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
Knob spring is connected by dynamic plate, driver plate with square tongue drawing plate；Lock core matches with key；When use key rotation lock core or twisting
During knob, driver plate can the movement of the side of drive tongue drawing plate, the side's of making tongue removes out of lockhole in button box；
Stroke and axially stop block include stroke limit groove, limited block and spacing torsion spring, the stroke limit groove side of being arranged on
The side of tongue drawing plate, one end of limited block is located in stroke limit groove, and the other end of limited block fits with spacing torsion spring；
Safety lock device includes the sliding block being fixedly connected with square tongue drawing plate and the slide block for being arranged on slider bottom；Sliding block
The other end be connected with lock core.
The sliding block is connected by sliding block spring with housing.
The bottom of the sliding block is provided with the sliding groove being engaged with slide block, and the sliding groove can stir row to slide block
Cheng Jinhang is spacing.
The matching part of the slide block and sliding block is in circular arc.
The panel is fixedly connected with housing by hexagonal countersunk head spline screw.
The present invention has the advantages that using after said structure：
1. the setting of above-mentioned stroke limit groove and limited block, can the stroke that moves radially of other side's tongue carry out spacing, prevent lock
The gouging abrasion of tongue clamping stagnation and dead bolt and button box etc. is bad.
2. the setting of above-mentioned spacing torsion spring, by the axial compression to limited block, on the one hand can cause the lockset of the application,
Coordinate more flexible, no clamping stagnation；In addition can be spacing with locking to being carried out on square tongue axial direction, the theftproof performance of door is greatly promoted.
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,
Can the side's of making tongue further extend, carry out backward hold, it is not necessary to could be locked using key, it is easy to use.
4. the setting of above-mentioned side's tongue strong magnet and button box magnet, after square tongue is locked, square tongue is not in radial direction and axle
To movement, can the side's of making tongue and button box cooperation it is more firm.
