Description

Safety durable can fix door lock

Technical field

This utility model is related to a kind of door lock, and more particularly to a kind of safety durable can fix door lock.

Background technology

Door lock is every household all anythings, and the safety of door lock is extremely important, and present lawless person can think to the greatest extent one Cut method and go theft of unlocking, for relatively easy door lock, somebody directly just can be opened using a special card, so Very big threat can be brought to the property of family and personal safety.

The life-span of some door locks is shorter and shorter, wherein has individual reason precisely due to the use time of door lock is longer, dead bolt Flexible dumb, lead to switch gate inconvenient it is sometimes necessary to very big strength could be closed and be visited, and also logical on door lock Often there is a fixing device, need at ordinary times to ensure that door is normally open it is not necessary to lock, therefore, just using a fixing device To fix switch lever, but operation comparatively laborious it is necessary to bimanualness, one pulls out switch lever, and another handss operate Fixing device fixing switch lever, for holding the people of thing on hand, using inconvenient.

Utility model content

, mainly solving the technical problems that providing a kind of more robust, safety is higher and can singlehanded consolidate for this utility model The safety durable determining switch lever can fix door lock.

For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: a kind of safety durable can be fixed Door lock, including door lock body, dead bolt, lock core and switch lever, the sliding surface of dead bolt is made up of three parts, and Part I is inside The curved surface of depression, Part II is plane, and Part III is outwardly curved surface, and Part I is tangent with Part II, the Two parts are tangent with Part III；Switch lever one end abuts a spring, for reset switch pull bar, door lock body also sets There is pull bar fixing device, on the motion track of switch lever, pull bar fixing device is hook-type and connects pull bar fixing device In door lock body interior, pull bar fixing device is rotatable, and can be resetted by elastic partss.

Further, dead bolt is provided with a breach from top to bottom.

Further, the tip of dead bolt is rounded down.

Further, dead bolt is provided with spacing preiection.

Further, the face that the pull bar fixing device of hook-type is contacted with switch lever is inclined-plane.

Beneficial effect: the sliding surface of dead bolt is divided into three parts by this utility model, has taken into full account the stress of dead bolt so that locking Stretching of tongue is sensitiveer, and service life is longer, and being provided with breach can increase safety, be additionally provided with the pull bar facilitating one-handed performance Fixing device, structure is simple, easy to use.

Brief description

Fig. 1 can fix the better embodiment schematic diagram of door lock for this utility model safety durable.

Fig. 2 is the partial schematic diagram of dead bolt.

Fig. 3 can fix the top view of the partial internal structure of door lock for this utility model safety durable.

Specific embodiment

Below in conjunction with the accompanying drawings this utility model is described further.

As shown in figures 1 and 3, a kind of safety durable can fix door lock, including door lock body 1, dead bolt 2, lock core and switch Pull bar 3, the sliding surface of dead bolt 2 is made up of three parts, and Part I 21 is the curved surface being recessed slightly inwards, and Part II 22 is flat Face, Part III 23 is outwardly curved surface, and Part I 21 is tangent with Part II 22, Part II 22 and Part III 23 is tangent, and when closing the door, the Part I 21 of dead bolt 2 contacts doorframe, first because Part I 21 caves inward Curved surface, so dead bolt 2 starts to be easier to shrink than the dead bolt (being directly the dead bolt of a plane) of general door lock most, second Divide 22 to be a plane, the Part II 22 of dead bolt 2 just can be made using inertia after Part I 21 for the dead bolt 2 light Shrink, because Part III 23 is slightly outwardly curved surface, so the Part III 23 of dead bolt 2 can shrink more easily, The sliding surface of dead bolt 2 adopts such structure, can be more more flexible than general dead bolt 2 shrinks, and after a very long time, also can compare General dead bolt 2 is more flexibly it is possible to extend the service life of door lock；Dead bolt 2 is provided with a breach from top to bottom 24, if lawless person wants to unlock using special card, card can directly be snapped on breach 24 it is impossible to continue to hold Lock, improves the safety of door lock；The tip of dead bolt 2 is rounded down, in case the body of user is scratched or clothes is not by Careful hang bad, dead bolt 2 is provided with spacing preiection 25 so that the length stretched out of dead bolt 2 is certain.

As depicted in figs. 1 and 2, switch lever 3 one end abuts a spring 26, for reset switch pull bar 3, door lock body It is additionally provided with pull bar fixing device 4, on the motion track of switch lever 3, pull bar fixing device 4 is pull bar fixing device 4 on 1 Hook-type is simultaneously connected to inside door lock body 1, and pull bar fixing device 4 is rotatable, and can be resetted by elastic partss, during enabling, draws Dynamic switch lever 3 can be opened the door, and maintains a normally open state if necessary to door lock, then slightly use bigger strength Drawing switch pull bar 3, will Switch lever 3 is pulled to the hook of contact pull bar fixing device 4, is contacted with switch lever 3 by the pull bar fixing device 4 of hook-type Face is inclined-plane, pull bar fixing device 4 can be made to rotate, when switch lever 3 moves certain journey to so pulling on switch 3 pull bars Degree, pull bar fixing device 4 can be resetted due to the elastic partss within door lock body 1, thus switch lever 3 is hooked, so just Can be directly fixing by switch lever 3 using handss, keep door lock normally opened, if desired close door lock, then directly that pull bar is solid Determine device 4 and rotate, switch lever 3 will be rebounded in the presence of spring 26, and door lock is lived.

The sliding surface of dead bolt 2 is divided into three parts by this utility model, has taken into full account the stress of dead bolt 2 so that the stretching of dead bolt 2 Contracting is sensitiveer, and service life is longer, and being provided with breach 24 can increase safety, is additionally provided with and facilitates the pull bar of one-handed performance to fix Device 4, structure is simple, easy to use.

These are only embodiment of the present utility model, not thereby limit the scope of the claims of the present invention, every utilization is originally The equivalent structure that utility model description and accompanying drawing content are made, is directly or indirectly used in other related technical fields, all In the same manner within scope of patent protection of the present utility model.
