Description

Anti-drill key checking number lock

The utility model relates to the improvement invention of a kind of comprehensive cylinder lock and coded lock characteristics, is specially adapted to safety cabinet, dwelling house door and other strick precaution field and occasion.

For many years, the various door locks, particularly safety cabinet lockset that sell the domestic market mostly are frame for movement cylinder lock or manual coded lock greatly, its poor safety performance, and also the exposed parts of lockset does not adopt the desirable precautionary measures, subjects to destroy.The pellet shot from a slingshot part or the cryptopart of lockset all are independent existence, work alone, and have experience person just can aim at password or push pellet shot from a slingshot aside with feel, thereby reach the purpose of committing theft.

The purpose of this utility model provides and a kind ofly adopts key check the number to open, have perfect safety energy, pellet shot from a slingshot part and cryptopart is used in combination and form the anti-drilling key combination lock of one with cryptopart.

The utility model is achieved in that whole lockset is by lock body, fixed cover, anti-jumping through hoops, lock core and parts thereof and master, main members such as passive rotor and rotating shaft are formed, the lock core parts are housed in the lock body, its outer equipped fixed cover, key insertion end at lock core is provided with anti-jumping through hoops, its other end has and is connected the dovetail groove of using with rotating shaft, anti-jumping through hoops center has cross recess, its garden is shaped on U-lag on week, be shaped on the groove that matches with the steel ball of packing into wherein in the corresponding position of fixed cover one end endoporus hole wall, initiatively rotor is housed in rotating shaft, at the lock body left end passive rotor and spring are housed, initiatively rotor is to adopt cottor pin to be fixed with being connected of rotating shaft, between the main passive rotor pad is housed.

Because of edge outside the key insertion end of lock core is provided with anti-jumping through hoops, the high rigidity anti-drill pin is housed on it, lock core does not have exposed parts, so improved the anti-anti-drilling performance of dialling; Because lock core and rotating shaft coupling is formed password check mark parts, and the unlatching pellet shot from a slingshot and the school password is all used key operated, so to unblank with the feel experience be irrealizable.

Introduce the utility model design feature and mode of occupation in detail below in conjunction with the accompanying drawing illustrated embodiment.

Fig. 1 is the utility model assembly structure figure.

Fig. 2 is that the utility model A is to view.

Wherein: the 1-key, the 2-fixed cover, the 3-steel ball, the anti-jumping through hoops of 4-, the 5-nut, the 6-lock core, the 7-rotating shaft, the 8-cottor pin, the 9-spring, 10-is rotor initiatively, 11-pad, the passive rotor of 12-, 13-lock body, 14-anti-drill pin.

Accompanying drawing 1,2 has provided overall structure of the present utility model, this anti-drilling key combination lock is made up of members such as lock body 13, fixed cover 2, anti-jumping through hoops 4, lock core 6, active rotor 10, passive rotor 12 and rotating shafts 7, except that lock core 6 is the brass material, all the other latch fittings all adopt common straightcarbon steel or high quality carbon knot steel to do.Lock core 6 is housed in the lock body 13, its outer equipped one has flange and externally threaded fixed cover 2, an equipped nut 5 on the fixed cover 2, key insertion end at lock core 6 is provided with anti-jumping through hoops 4, its other end has and the quiet dovetail groove of joining logotype mutually of rotating shaft 7 end face forked tail platforms, anti-jumping through hoops 4 centers have the cross recess that inserts key 1, its garden is shaped on U-lag on week, the relevant position of fixed cover 2 one end endoporus hole walls is shaped on groove, between the U-lag a plurality of steel balls 3 are being housed in this groove and the anti-jumping through hoops 4, initiatively rotor 10 is housed in rotating shaft 7, outside the lock body 13 of fixed cover 2 left ends, be set with passive rotor 12 and spring 9, initiatively be that employing cottor pin 8 is fixed being connected between rotor 10 and the rotating shaft 7, initiatively between rotor 10 and the passive rotor 12 pad 11 is housed, and at active rotor 10, respectively have 30 * 4 millimeters rectangular through slot on the passive rotor 12, width one side of groove respectively is provided with dog.

During use, this lock is as being installed on the safety cabinet, pellet shot from a slingshot part and Cipher mechanism can be used in combination, earlier the cross recess of key along anti-jumping through hoops 4 is inserted and rotated, when key 1 continues to insert in the lock core 6 the cross recessed enable possition, all pellets shot from a slingshot promptly are in opening, at this moment continue left-right rotation key 1, lock core 6 drives rotating shaft 7 and rotates together, and rotating shaft 7 drives active rotor 10 and makes garden Zhou Yundong, dog on the active rotor 10 drives passive rotor 12 and rotates repeatedly, check the number, behind the precalculated position that reaches pre-encryption, when initiatively the rectangular through slot on the rotor 10 passive rotors 12 is in same horizon, promptly finished the operation of checking the number, lockset has also just been opened.When shutting, close key 1 to the doorstep, dial disorderly inner permutations of code order, transfer to key 1 to get final product.

If this lock is used in common door, security door and other occasion, the drilling-preventing structure that it is unique--anti-jumping through hoops 4 will play crucial antitheft effect, generally only need this moment to use its lock cylinder control keying to get final product, in particular cases, also but pellet shot from a slingshot, password are used in combination, and impose two controls.
