Abstract
The utility model discloses a lock-tongue of an anti-theft door lock, which comprises an outer casing, an inner casing and a piston; wherein the piston is pressed by the outside force when closing the door which makes a piston rod move toward a blocking sheet, an inclined plane of the piston rod presses the blocking sheet moves toward the other plane and leaves the inner casing runner, the inner casing shoots outward with the function of the spring to achieve the goal of security. When the spherical cap of the piston is outside the outer casing, the inner casing is blocked in the outer casing by the blocking sheet; the fringe of the outer casing is even with the fringe of the inner casing and the door is open. The inner casing of the lock-tongue of an anti-theft lock of the utility model shoots out when the door is closed, which ensures that the door cannot be opened with a slice, thus guarding against theft.
Description
Technical field the utility model relates to a kind of door lock, particularly a kind of safe-guard door lock dead bolt.
Background technology has the various ball lock dead bolts of city's field boundary now, generally is that dead bolt has an angle, and its shortcoming is just can open door with thin slice reeve, and dangerous, though also there are some dead bolts to be arranged to rectangle, switch door inconvenience.
Summary of the invention purpose of the present invention is exactly at the deficiencies in the prior art, provide a kind of can not inject with thin slice just can open door, the safe-guard door lock dead bolt of burglary insurance.
The technical solution of the utility model is as follows: a kind of safe-guard door lock dead bolt, by overcoat, interior cover, piston is formed, have T shape chute on the parallel wall relative of described overcoat with axis, bottom at T shape chute is provided with guide rail, the guide groove of guide rail is that T shape is furnished with card in it, the spring connector of one end of card inserts in the stage clip, the tail end of stage clip is fixed on the inwall of overcoat, the middle part of guide rail, card all be provided with towards the limit of chute be parallel edges through hole,, the both sides of guide rail and overcoat connection are provided with gap, be used in the cover pass; Interior being sleeved in the overcoat, also be provided with chute with the corresponding position of T shape chute of overcoat, the bottom that chute passes T shape is extended downwards a bit of, is provided with baffle plate in the cover in the bottom position of chute, and the middle part of baffle plate is provided with and through hole, the position is corresponding, shape is identical through hole; One end of piston is spherical, and the circular flat center fixation of spherical crown is connected with piston rod, and its outside shape and through hole, shape are identical, and an inclined-plane is arranged at the bottom, top of piston rod; The through hole that the through hole, the through hole of chute, the through hole of card of cover in piston rod passes successively, the upper edge on inclined-plane place card is near below the limit of stage clip; Between the baffle plate of the guide rail of overcoat and interior cover, be furnished with ejector spring, between the circular flat of the spherical crown of the baffle plate of interior cover and piston, be furnished with back-moving spring.
Make piston rod to card motion when piston at closing time is subjected to the external force extruding, an inclined-plane of piston rod moves to another side to the compressing card, cover chute in leaving, in be enclosed within spring effect down outwards ejection reach the purpose of security insurance.When the spherical crown of piston was in the outside of overcoat, interior cover was stuck in the overcoat by card, and the edge of overcoat is concordant with the edge of interior cover, the state that door is in out.
A kind of safe-guard door lock dead bolt of the present utility model, as long as close the door, interior cover promptly stretches out, and makes door can not push burglary insurance with thin slice aside.
