Description

Key type puzzle lock core

The utility model relates to a kind of key-free lock annex, particularly push-button puzzle lock core.

The present key-free lock that uses has button, to change word formula etc. multiple, but its used password generally all immobilizes, and is difficult for memory, in case password is revealed then user oneself is difficult to change, so make things convenient for inadequately.

The purpose of this utility model is that a kind of improved push-button puzzle lock core will be provided, and its used password can interrelate with daily life, is convenient to memory, and can be changed voluntarily by the user at any time as required.

The purpose of this utility model is achieved in that this push-button puzzle lock core is by button, installing plate, the device that is installed in laminate in the lock core, lock pin, conversion lock pin position constitute with the locking plate that is connected dead bolt, press the unlock key that the surface has distinct symbols, make lock pin in laminate, pass locking plate and move up and down, make the locking plate that has the alternate eyelet of width in lock core or be stuck and maintain static, or be free to slide, thereby the purpose that reaches locking and unblank.

It is varied that the utility model advantage is on the button that used symbol can adopt, button the more, its password storage capacity is bigger; Used password can interrelate with the daily life term, in case when password is revealed, can change by user oneself, thus safe and reliable, be convenient to remember, easy to use.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1 is that the utility model master looks generalized section.

Fig. 2 is that generalized section is looked on the utility model left side.

Fig. 3 is the utility model exposed face schematic diagram.

Fig. 4 is the locking plate schematic diagram that is connected with dead bolt in this lock core.

Below in conjunction with accompanying drawing, describe concrete structure of the present utility model and working condition thereof in detail.

With reference to accompanying drawing 1～4, this push-button puzzle lock core is made of with the locking plate 8 that stretches out lock core and be connected with dead bolt on the door button, installing plate 4, the device that is installed in Box-shape lock in-core laminate with holes, lock pin 7, conversion lock pin position.The button submeter is worn the unlock key 3 and 1 two kinds of the reset keys that lock pin 7 is resetted of distinct symbols, and unlock key 3 used symbols are 26 English alphabets in the present embodiment, add an additional key, and symbol is ten, and 1 of reset key is used symbol ⊙; Have a lock pin 7 that can in laminate 9, slide at each unlock key 3 with square hole, this lock pin 7 is that waist both sides have groove, the cross section is square hexahedron, the lock pin width of this band groove, be slightly less than the narrow hem width degree of bar hole in the locking plate 8, make locking plate 8 when passing the waist of lock pin 7, can be free to slide; Lock pin 7 two ends trough rim width do not wait, so that make mutual dislocation between lock pin after installing, and fixing locking plate.Reset key 1 is connected by the permanent magnet junction plate 11 of key lever 2 with the lock core bottom; The device of conversion lock pin position is by unlock key 3 and key lever 5, reset key 1 and its key lever 2, is enclosed within the back-moving spring 6 on the key lever 5 of unblanking, back-moving spring 10, the U-shaped permanent magnet 12 of lock pin bottom, the spring leaf 13 that is connected in the magnet junction plate 11 under the key lever 2 that resets and magnet junction plate 11 and reset key are resetted and is constituted, for making key lever and lock pin position stability and being free to slide in lock core, laminate 16 is provided with circular hole, so that pass key lever and U magnet 12, laminate 9 is provided with square hole, and lock pin 7 can be free to slide therein; ［ shape plate 15 is clipped in the middle of two blocks of laminates 9, makes the locking plate 8 must be in 9 slips of laminate, and when sliding to the end, square cell is just in time aimed at each lock pin on the locking plate 8; Locking plate 8 is one to have the plates of bar hole, is installed between two square hole plates 9, and bar hole is provided with the square opening that has enlarged with the key position proper alignment, so that lock pin 7 slides in square opening.

When lock core is installed, after relevant button, spring, permanent magnet install, with rivet 17 the part parts are fixed, laid lock pin then, make and the relevant lock pin of institute's encryption, one on the narrow limit of groove is towards outdoors, and then narrow of all the other each lock pins are in door; When changing password as need, only need by bolt 19 bonnet to be opened, the installation direction that changes lock pin gets final product.

During use, push reset key 1, U-shaped permanent magnet 12 leaves lock pin 7, and lock pin 7 is under the effect of back-moving spring 10, pop up, and withstand on the key lever 5, at this moment, because of the waist groove of lock pin 7, stagger mutually, and locking plate 8 is stuck in the lock core, can not slide, become lock-out state; Push the unlock key relevant 3 then with password, corresponding lock pin is pressed to U-shaped permanent magnet 12, and lock pin 7 is held by magnet 12, the magnetic pull between them, tension force greater than spring 10, lock pin 7 keeps motionless, makes all lock pin 7 waist grooves in the lock core, all aims at locking plate 8, at this moment, pivot link 20 can drive locking plate 8 and be free to slide, and becomes unlocking condition.Unlock key 3 and reset key 1 under the effect of spring 6 and spring leaf 13, all can set back after pressing respectively at every turn automatically.

In the present embodiment,, can compile 67108862 kinds of passwords,, then can form the twice of above-mentioned password quantity as additional key is also counted only with 26 English alphabets; For example " friend opens the door " enrolled in the lock, its Chinese phonetic alphabet is PENG YOU KAI MEN, is English, contains P, E, N, G, Y, O, U, K, A, I, 11 corresponding lock pins of letter therewith incited somebody to action in 11 phonetic alphabet of M, enrolls as stated above in the lock core to get final product; In like manner, also can adopt the English coding, in addition, open bonnet, adjust the front and back placement direction of relevant lock pin, can work out out multiple password.
