The specific embodiment

Referring to Fig. 1-Fig. 5, provide the two of a kind of sliding door to open handle lock, comprise the lock box 1 that is fixed on the doorframe inboard, be covered with the A locking closure 2 of band handle on lock box 1, A lock core 3 passes A locking closure 2 and stretches in lock box 1, is fixed with B locking closure 4 outside doorframe, and B lock core 5 passes B locking closure 4 and stretches in lock box 1.Lock box 1 center is provided with linkage unit 6, and linkage unit 6 comprises from inside to outside lock core tube 7, spacing ring 8 and be connected with the pinion stand 10 of pushing hands 9, and the three is socketed successively, A lock core 3 and B lock core 5 with dead bolt, insert in lock core tube 7 from both sides respectively.The both sides of linkage unit 6 are equipped with lock hook assembly 11, each lock hook assembly 11 includes latch hook 12 and below connected tooth bar 13 thereof, two toothed rack 13 are pressed close to respectively the both sides inwall of lock box 1, and all with pinion stand 10 on gear engagement, the hook end of two latch hooks 12 oppositely stretches.Lock core tube 7 with the pressed on ring bottom and the top of spacing ring 8, be respectively equipped with corresponding A loxosis 14 and B loxosis 15 of fitting, relatively be connected with two sagging positive stop strips 16 on spacing ring 8, pinion stand 10 inwalls are provided with 17, two positive stop strips 16 of two jacks and the 17 corresponding grafting respectively of two jacks relatively.On the outer wall of lock core tube 7, cover has back-moving spring 18, and the upper end of back-moving spring 18 pushes against the inwall of spacing ring 16.Lock box 1 bottom and lock core assembly 11 relative positions are provided with circular hole 19, and its circumference is connected with outward respectively and two two spacing holes 20 that positive stop strip 16 is corresponding relatively.

When the user is rotating key outdoors, lock core tube 7, pinion stand 10, tooth bar 13 link, and tooth bar 13 moves and drives two latch hooks 12 and outwards open from lock box 1, catches on the lockhole on door, realizes locking.Meanwhile, A loxosis 14 presses down and throws off B loxosis 15, spacing ring 8 is moved down, back-moving spring 18 is compressed, two positive stop strips 16 move down respectively thereupon and insert in two spacing holes 20, pinion stand 10 namely is stuck, only have with the release of key ability, like this, if the indoor undesirable who has the jumping window to enter, he pulls pushing hands 9 in any case, pinion stand 10 can not rotate yet, also just can't unblank, open the door and run away, thereby can ensure better user's property safety, and be conducive to more effectively arrest and frighten the undesirable.

To enter indoor and work as the user, or other indoor users are when wanting to open the door, with key outdoors or indoor rotation key, lock core tube 7 rotates, and the elastic force of back-moving spring 18 makes to move on spacing ring 8 and resets, and A loxosis 14 and B loxosis 15 are recovered to fit, two positive stop strips 16 with on move and throw off two spacing holes 20, pinion stand 10, tooth bar 13 namely link with the rotation of lock core tube 7, and tooth bar 13 moves and drives in two latch hook 12 retraction lock boxes 1, realizes unblanking.

When indoor, pull pushing hands 9 as user oneself, pinion stand 10, tooth bar 13 are linked, can make two latch hooks 12 open or retract, realize indoorly locking or unblanking.

Above-described embodiment is preferred embodiment of the present utility model, and all and the similar structure of the utility model and the equivalence of doing change, and all should belong to protection category of the present utility model.
