Abstract
The utility model discloses a theft-proof door lock. The theft-proof door lock has the main structure that in a lock fastener box (2), one end of a push-pull sheet (3) connected with an upright rotating shaft (4) can be pushed by the bolt (9) of a lock box (10), and the other end is hinged with an anti-prizing sheet (6) with a reset spring (7); the bolt (9) can push the push-pull sheet (3) up at the time of going into the lock fastener box (2) from a bolt inlet (12), and the anti-prizing sheet (6) can extend out of the lock fastener box (3) and go into the lock box (10); thus, the anti-prizing sheet (6) can cover the bolt (9), the case that the inserting sheet which is inserted in the gap between the lock box (10) and the lock fastener box (2) can not touch the bolt (9) is ensured, and the theft-proof action is played. The utility model has the advantages of simple structure, reliable performance and low cost.
Description
The utility model relates to a kind of door lock.
Existing door lock, in order to close the door conveniently, dead bolt mostly is band inclined-plane tongue body greatly.But this be locked in lock after, can in the slit between lock box and the keeper, insert thin slice and dead bolt is pushed up back, theftproof performance is poor.Dual fail-safe, three insurance locks of market appearance are in recent years removed by inserted sheet though can prevent lock, and complex structure, cost height must rotate in lockhole with key and lock a door, and use inconvenience.
The purpose of this utility model is, designs a kind of safe-guard door lock, the pick-proof sheet is stretched out and shelters from dead bolt, makes it and can not be backed down by inserted sheet, plays antitheft effect.
The technical solution of the utility model is, the keeper that it comprises the lock box of core with lock and dead bolt and the dead bolt inlet is arranged, its design feature is, vertical rotating shaft is housed in the described keeper, an end that is fixedly connected on the push-pull piece in the described vertical rotating shaft be positioned at the dead bolt top that can be entered keeper and the position and the other end connects with the end of hinge with the pick-proof sheet, and this link links to each other with an end of back-moving spring, the other end of back-moving spring is connected on the keeper box wall through fixed bar, the other end of described pick-proof sheet can stretch out and parallel with the moving direction of dead bolt from the outlet of the pick-proof sheet of keeper, has on the described lock box with the corresponding pick-proof sheet inlet of the pick-proof sheet outlet of keeper.
Make below in conjunction with accompanying drawing and to further specify.
Description of drawings: Fig. 1 and Fig. 2 are respectively the Facad structures of lock box and keeper, and Fig. 3 is an A-A sectional view shown in Figure 1, and Fig. 4 is a B-B sectional structure shown in Figure 2.In the drawings:
The outlet of 1-pick-proof sheet, 2-keeper, 3-push-pull piece, the vertical rotating shaft of 4-, 5-hinge, 6-pick-proof sheet, 7-back-moving spring, 8-fixed bar, 9-dead bolt, 10-lock box, 11-pick-proof sheet inlet, 12-dead bolt inlet.
By accompanying drawing as can be known, the utility model comprises band lock core and the lock box (10) of dead bolt (9) and the keeper (2) that dead bolt entrance (12) are arranged, its design feature is, vertical rotating shaft (4) is housed in the described keeper (2), push-pull piece (3) be fixedly connected on the upper and one end of this vertical rotating shaft (4) be arranged in dead bolt (9) top that can be entered keeper (2) and the position, and the other end of push-pull piece (3) connects with the end of hinge (5) with pick-proof sheet (6), and same back-moving spring (7) one ends of this link link to each other, the other end of described back-moving spring (7) is connected on keeper (2) the box wall through fixed bar (8), the other end of described pick-proof sheet (6) can from the pick-proof sheet of keeper (2) outlet (1) stretch out and the moving direction of same dead bolt (9) parallel. Described lock box (10) has the pick-proof sheet entrance (11) corresponding to pick-proof sheet outlet (1) of same keeper (2).
The course of work of the present utility model and design principle are, push-pull piece (3) and the leverage of vertical rotating shaft (4) formation take described rotating shaft (4) as fulcrum, when dead bolt (9) enters keeper (2) by dead bolt entrance (12), head on the end reach of push-pull piece (3) and make push-pull piece (3) rotate an angle take described rotating shaft (4) as the axle center, the other end of this push-pull piece (3) then makes pick-proof sheet (6) be stretched out by described outlet (1) and enters in the pick-proof sheet entrance (11) of lock box (10), back-moving spring (7) is stretched simultaneously, after entering dead bolt box (2), dead bolt (9) make thus pick-proof sheet (6) shelter from dead bolt (9), blocked by the pick-proof sheet and can not contact dead bolt (9) by the inserted sheet that inserts in the slit between lock box (10) and the keeper (2), play anti-theft function. When unblanking, along with withdrawing from of dead bolt (9), back-moving spring (7) resets pick-proof sheet (6) and push-pull piece (3), and namely pick-proof sheet (6) is voluntarily by described Entrance (11) withdraws from and is retracted in the keeper (2).
As known from the above, the utility model can prevent that inserted sheet from making door-lock opening by inserting in the slit between lock box and the keeper, plays anti-theft function, and has simple in structure, dependable performance, characteristics that cost is low.
Embodiment: according to the safe-guard door lock of accompanying drawing and said structure, adopt prior art door latch structure and size, pick-proof sheet (6) is 2.5 centimetres with the height (being Fig. 1 and vertical dimension shown in Figure 2) of dead bolt (9), push-pull piece (3) is 1 millimeter steel disc with pick-proof sheet (6), and the stroke of described (6) is 1.5 centimetres.
