CN2675793Y - Anti-theft door lock opened by key with column bits - Google Patents

Abstract

The utility model provides an anti-theft door lock opened by a key with column bits, belonging to a lockset of the daily used article. The utility model is characterized in that the key is made into the disk shape; a handle is arranged on the upper surface of the disk; column bits with different length are arranged on the lower surface of the disk; corresponding to column bits, bit holes are arranged on one end face of a rotor for column bits being in and out; ball holes are provided under the bit holes; corresponding to the ball holes, concentric spring holes are arranged on a stator; ball sets composed of two balls with different length, and springs are respectively imbedded into ball holes and spring holes; the rotor and the stator are arranged in a head ring on the door; the pitman shaft of the rotor passes through the hole of the central shaft of the stator to bare out of the bottom of the head ring; a connecting rod hinged at the tail end of the pitman shaft can be inserted into a lock case which can open or close a lock bolt. The utility model which has simple structure and easy use can increase ball holes as the number of bits, and thus the door can not be opened with a fitting key, enhancing the anti-theft property.

Description

The safe-guard door lock that the cylinder tooth-engraved key is arranged

Technical field

The utility model belongs to the lockset in the daily goods, particularly a kind of safe-guard door lock that is furnished with the cylinder tooth-engraved key in the key plane.

Background technology

At present, be used for the door lock on common door, the security door, be built-in lock again, form by hinged connecting rod of key, tapered end, Tou Quan, lock body fixed head, tapered end tail end and lock box that dead bolt is housed, when door lock is installed, on door, have the hole that can hold the head circle, from the appearance of door the head circle is inserted in the hole, in the Tou Quan hole, inserts tapered end, the interior table of door with screw make the lock body fixed head fixedly tapered end on door, and make the connecting rod of tapered end tail end exposed, insert in the lock box of energy unlock deadbolt; Wherein tapered end is by cylindrical rotor, stator, pellet shot from a slingshot, spring, connecting rod is formed, the cylindrical rotor of in stator, packing into, uniform concentric pellet shot from a slingshot hole respectively on the same longitudinal centre line of the contact surface of stator and rotor, its quantity has only 5 at most, in the pellet shot from a slingshot hole, put into length respectively, the short pellet shot from a slingshot that differs, behind each pellet shot from a slingshot, put into compression spring and shutting, end face center at rotor one end, have the keyhole that can hold the pancake key, the lower end of key is processed with tartar different in size, this serial tartar is according to the quantity in pellet shot from a slingshot hole and the length different size of pellet shot from a slingshot, carry out series and compile out number through digital equal difference permutation and combination, the corresponding tartar of number, corresponding with this tartar, in the pellet shot from a slingshot hole, insert pellet shot from a slingshot different in size, spring.After key inserted keyhole and coincide with it, rotor just can rotate in stator, and the connecting rod that is hinged on the rotor bottom just rotates, connecting rod just by the unlatching of the opening mechanism in the lock box, close a lock that dead bolt is achieved, open.This pin tumbler lock, widely-used, but often opened by bad person's bitting, can not be antitheft, trace it to its cause and be, because of being subjected to the size constrained of the cylinder of rotor, on the cylinder periphery, can not increase the pellet shot from a slingshot hole count, so can not increase through the tartar coding of array combination, the existing tartar numbering that mostly is 5 shell holes most, long-term use, well known deeply is again let alone entering computer age, easier decoding, be easy to lock be opened, do not have antitheft, safe effect by lawless person's bitting.

Summary of the invention

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, and provide can increase tartar numbering number and improve theftproof have simple in structure, a kind of safe-guard door lock that the cylinder tooth-engraved key is arranged of coincidence gate lock construction.

The purpose of this utility model realizes with following technical scheme: the theftproof lock that the cylinder tooth-engraved key is arranged, comprise the hinged connecting rod of key, tapered end, Tou Quan, tapered end tail end, the lock box of dead bolt is housed, it is characterized in that: key is made disc, upper disk surface has handle, following card is furnished with the long and short cylinder tartar that differs, corresponding with the cylinder tartar, in an end face of rotor have make the cylinder tartar into and out of the tartar hole, below the tartar hole, have the pellet shot from a slingshot hole, corresponding with the pellet shot from a slingshot hole, on stator, have the spring eye concentric with the pellet shot from a slingshot hole; There is pitman shaft at the center, other end of rotor, corresponding with pitman shaft, have axis hole in stator center, in pellet shot from a slingshot hole, spring eye, insert long and short pellet shot from a slingshot group and the spring that differs, rotor, stator are packed in the head circle on the door, make the pitman shaft of rotor pass the stator center hole and be exposed to the head circle at the end,, and make connecting rod end be inserted with unlatching, close in the lock box hole of dead bolt in its terminal articulated linkage.At first stator is fixed in the head circle, in spring difference inserting spring hole, to be furnished with cylinder tooth different in size corresponding with the key card, in the pellet shot from a slingshot hole, adorn pellet shot from a slingshot group different in size respectively, the pellet shot from a slingshot group is made up of two pellets shot from a slingshot, a pellet shot from a slingshot that length is identical is arranged respectively in all pellet shot from a slingshot groups, because pellet shot from a slingshot hole, spring eye is a concentric holes, pellet shot from a slingshot can enter in the pellet shot from a slingshot hole of rotor in the stator under the effect of spring, it can not be rotated, and key is with rotor equal number and the concentric different cylinder tartar of length to be arranged, the length of cylinder tartar on the key, the short pellet shot from a slingshot length that depends in the rotor because the cylinder tartar must be identical with the another side of rotor with the pellet shot from a slingshot size addition in the rotor, so just returns in the stator pellet shot from a slingshot in the stator, open but rotor is freely rotated with regard to drivening rod, close dead bolt; Because the contact surface of key and rotor is a circular flat, area is bigger, cylinder tartar on the key card can be on the different angles position arranged distribution, accordingly, at stator, also be furnished with more concentric pellet shot from a slingshot hole on the rotor, can reach 18 at most, minimum is 6, because the pellet shot from a slingshot hole can process not according to same angle fully, so the key of this lock is inserted not advance in another lock, if one has been locked 12 keyholes, and have only eight garden post tartars on the key, wherein four pellets shot from a slingshot and rotor simultaneously, if without key, with matching well repeatedly of needs several thousand times, lock can not be opened, thus the purpose of realization the utility model safe antitheft.

Compared with prior art, the utility model can increase the pellet shot from a slingshot hole count, and the tartar numbering of lock is significantly increased, and is difficult for joining lock and opens and guarantee antitheft, and simple in structure, easy to use.
