Description

The direct-push cylinder lock

Technical field

The utility model relates to a kind of anti-theft device, relates in particular to a kind of lock.

Background technology

Traditional lock, in use key is stretched in the lockhole and rotate, dead bolt is rebounded in lockhole, thereby open lock, but traditional being locked in when opening lock twists off key in lock core easily, key also can only be selected metal material for use, to resource scarcity now, metal key has increased the cost of production of lock undoubtedly.Chinese patent application a kind of pushing antitheft lock that number has been 200610155152.4 disclosure of the Invention, include the locking bar that lock housing, lock core, end have notch, lock housing is provided with the lockhole that inserts for locking bar, lock core is contained in the interior enclosed cavity of lock housing, and in this cavity, vertically move, in this cavity, also be provided with the back-moving spring that lock core is resetted simultaneously; The upper inner of lock core has can snap in the protuberance that is positioned at the notch on the locking bar, and the bottom of lock core is locked in the lock housing by billiards lock structure; The bottom of described lock housing has the keyhole of vertical setting; The middle part of described lock core has the catch bar of horizontally set.

Summary of the invention

The purpose of this utility model is intended to overcome the defective of prior art, and a kind of low cost of manufacture is provided, direct-push cylinder lock easy to use.

Direct-push cylinder lock described in the utility model, by lockhole, dead bolt, lock core, back-moving spring, locking bar and key are formed, the top of key is the inclined plane, have on it and the corresponding groove of lock core marble quantity, lock core is made up of separate fixed lock core and mobile lock core, fixed lock core is fixed on the wall of lock chamber, mobile lock core be positioned at fixed lock core under, and combine with the fixed lock core face, porose in the fixed lock core, spring and pellet shot from a slingshot are arranged in the hole, mobile lock core is run through in the hole of mobile lock core, its position is corresponding with the position and the quantity in fixed lock core hole with quantity, and pellet shot from a slingshot is arranged in the hole, and an end of dead bolt is fixedlyed connected with mobile lock core, the junction, one projection is arranged, the notch clamping on the other end and the locking bar, lockhole be positioned at lock core under, back-moving spring is positioned on the lock chamber wall relative with lockhole, the end of back-moving spring contacts with dead bolt is vertical, and the thickness of key and the size of lockhole are complementary, have on the key with lock core on the corresponding groove of marble amount and position.

Described dead bolt is " U " shape.Hole in the described lock core is 1-20.The length of mobile lock core displacement is greater than the degree of depth of notch on the locking bar.Key is straight plate, and the depth of groove on it and the length of pellet shot from a slingshot are complementary.

Direct-push cylinder lock described in the utility model, pellet shot from a slingshot length difference in the lock core, the elasticity of spring in addition, make in fixed lock core and the mobile lock core corresponding aperture that bonding surface does not become same horizontal plane between pellet shot from a slingshot on the contact surface of two lock cores, the dislocation of pellet shot from a slingshot section, block mobile lock core, make it and can not be subjected to displacement, lock is in locking states.After key inserts lockhole, make that with the groove that pellet shot from a slingshot length, quantity and position are complementary bonding surface becomes same horizontal plane at the contact surface of two lock cores between pellet shot from a slingshot on the key, be that the pellet shot from a slingshot section is on a horizontal plane, under the straight thrust of key, mobile lock core is subjected to displacement along the direction that key inserts, the dead bolt that is fixed thereon also is subjected to displacement thereupon, makes the dead bolt that is stuck in the notch shift out notch, and lock is promptly opened.When dead bolt was subjected to displacement, back-moving spring was subjected to the compressing of power, is in contraction state, and when the key taking-up, external force disappears, and back-moving spring flicks, and makes mobile lock core get back to original position, will lock locking.For the theftproof performance that guarantees to lock, pellet shot from a slingshot length in the quantity changeable of lock core endoporus, lock core and discharging order can be different, guarantee the otherness and the safety of lock.Projection in dead bolt and mobile lock core junction, can block the top of key, strengthen the power of mobile lock core displacement, the new shape of this practicality adopts the displacement of mobile lock core and " U " shape dead bolt to reach the purpose of locking or unblanking, just directly push away along the key direction of insertion and can open lock so only need insert key when using, having avoided traditional locks is that the twisting key excessive key that causes of exerting oneself ruptures unblanking.Because key only need insert and get final product, the hardness of key itself is required also just to decrease, as long as certain degree of hardness is arranged, and be difficult for the material of generation deformation such as duroplasts, PVC etc. all can, thereby reduced the cost of production of locking.
