Both can open certain width in order to satisfy door and window, and can play the antitheft effect of locking again, can on limit locking pieces, offer forward and backward spacing lockhole; The user need open the door and window certain width and play and lock the antitheft time spent of doing, only need slide door or window to certain position (refer to door and window open certain width), dead bolt is under the spring force effect, and the sleeve fastening is gone in the front limit lockhole automatically, and the realization door and window is opened certain width and had the anti-benefit effect of locking; If door and window need be closed fully, can pass through the hand pull handle, make the dead bolt outer end leave the front limit lockhole, this moment again slide door or window to closure state, dead bolt is under the spring force effect, and just the sleeve fastening is gone in the spacing lockhole in back automatically, realizes automatically locking of door and window sealing; And total is simple, reasonable, operates simple and easy, convenient; Certainly, can also offer a plurality of forward and backward spacing lockholes according to the design needs on the limit locking pieces, open different width to satisfy door and window, and having the locking anti-theft feature.

The inner of described dead bolt is provided with the spring guide groove, and spring can stably be arranged on the spring guide groove, the spring guide groove inwall of spring one end card top dead bolt, and the other end and housing offset, so that spring has certain elastic reaction.

The bottom of described housing is provided with stay hook, and base is provided with corresponding button hole, and housing fixes on the button hole of base correspondence by the stay hook hook of its bottom.

Have oval-shaped handle adjustment hole on the sidewall of the corresponding handling position of described housing, so that the length that stretches of regulating the dead bolt outer end by handle realizes unlocking function.

The beneficial effects of the utility model are:

(1) spring latch automatic door sash lock of the present utility model has simple and reasonable for structurely, and the door and window push-pull lock regularly can not damage lock body and door and window, and door and window both can open certain width, can play advantages such as the antitheft effect of locking again.
