Description

Key-type mechanical puzzle lock

(1) technical field

The utility model relates to lockset, specifically is a kind of key-type mechanical puzzle lock.

(2) background technology

The patent No. is that the utility model patent of 200420017049.X discloses a kind of " full machinery order key cipher lock ", by shell, lock pin, equipped lock core in the enclosure, key letter, bolt plate and clamp are formed, bolt plate and clamp are corresponding upper-lower position setting in lock core, offer the "T"-shaped groove that is positioned at the button below on the lock core on the both sides of bolt plate, be engaged in the "T"-shaped groove is respectively "T"-shaped cryptographic key, secondary key, clear key, cryptographic key, secondary key, the bottom of clear key is provided with spring, (the hook disengaging clamp of key letter) key letter is higher than the bolt plate plug face and withstands on the button bottom under the normal condition, this moment, cryptographic key stopped bolt plate, secondary key is opened bolt plate, the result is that bolt plate is by locked, press the cryptographic key lock and open bolt plate, bolt plate is opened, if but mistake is pressed secondary key, bolt plate is still by locked.Under the wrong situation of cryptographic key and secondary key, press the normal condition that clear key recovers cryptographic key and secondary key, press cryptographic key again.

In " full machinery order key cipher lock ", because the restriction of manufacturing process, the groove of unblanking of the unblank groove and the bolt plate of key letter is very little, is easy to be stuck; The recess of unblanking is offered in the position in dividing on the side of key letter with respect to bolt plate in addition, bolt plate is by opening when the recess of unblanking is in straight line, also offer the spring reset installing hole on the bottom of key letter and the lock core, cause the key letter complex structure thus, make the processing cost height.

(3) utility model content

At the weak point of original mechanical cipher lockset, the utility model provides a kind of simple in structure, durable key-type mechanical puzzle lock.

Can realize the key-type mechanical puzzle lock of above-mentioned purpose, comprise shell, lock core, key letter, clear key, button, bolt plate and clamp, wherein lock core is installed in the shell, what intermediate lateral was installed setting about the lock core is bolt plate and clamp, vertically respectively offer 6 keyholes that key letter is installed on the lock core of bolt plate both sides, button stretches out in shell, button corresponds respectively to each key letter and clear key in the enclosure, reducible key letter helps key to form by cryptographic key and shop, cryptographic key and shop help key to correspond respectively to button 1～No. 10, clear key is corresponding to " rice " word button, the symbol of unlock key is " # " number, and different is the utility model:

1, key letter all is designed to sheet, the back-moving spring of key letter clamps and places in the spring groove of offering in the key letter consistent with its direction of motion, the recess of unblanking that key letter is controlled bolt plate is located on the key letter of hook one side, the recess of unblanking of cryptographic key is positioned at the top, when cryptographic key is all pressed, the recess of unblanking can make bolt plate open certain distance and opens lock pin, the shop helps the recess of unblanking of key to be positioned at the middle part, the shop of upspringing helps the recess of unblanking of key to cooperate the cryptographic key of all pressing to make bolt plate open certain distance and opens lock pin, the shop helps key by mistake on time, and moving of restriction bolt plate pinned lock pin.

2, corresponding with sheet key letter keyhole is horizontal bar hole, the keyhole of bolt plate both sides respectively is on the straight line that parallels, also be processed with the blind hole equipped on the keyhole downwards with the key letter back-moving spring, the degree of depth of blind hole is less than the length of back-moving spring, and the key letter under the normal condition is upspring and is higher than the plug face at bolt plate place.

3, the dual-side with the bolt plate of above-mentioned key letter respective outer side edges is arranged with rib at interval, each rib corresponds respectively to the recess of unblanking of both sides key letter, when the rib correspondence is unblanked recess, the stagger key that is encoded when unblanking recess of the distance that the removable recess of unblanking of bolt plate is dodged, rib blocks and locked bolt plate.

Choose 6 cryptographic keies generally speaking, by the order of its cryptography, cryptographic key hook Q value in order from large to small, the hook of a last cryptographic key can not come off from clamp during by next cryptographic key with assurance.

The hook Q value of adjacent cryptographic key differs 0.3mm～0.4mm.

Behind selected 6 cryptographic keies, the shop helps key then to be 4, and the shop helps key to need not to set by ordering, and its hook Q value is linked up with between maximum Q value and the minimum Q value between cryptographic key.

Determined by the people for preventing 6 cryptographic keies, pressing 6 cryptographic keies simultaneously unblanks, two hooks of upper-lower position are set on a cryptographic key (except the cryptographic key of minimum Q value) at least, last hook Q value is less than lower draw-bar Q value, the recess of unblanking of two hook cryptographic keies moves down and is in top but passes to the top not, the recess of unblanking moves down distance and equals the height linked up with, when 6 cryptographic keies are pressed simultaneously, the hook of going up of two hook cryptographic keies is locked by clamp, and lower draw-bar is only the lockset position of coupler of this cryptographic key, therefore presses 6 cryptographic keies simultaneously and can not unblank.

Same reason helps two hooks that upper-lower position is set on the key at least two shops, on link up with the Q value less than lower draw-bar Q value.

The suitable thicknesses of sheet key letter is between 1.0mm～1.5mm, and intensity is enough.

Advantage of the present utility model:

The utility model key-type mechanical puzzle lock mainly improves the structure of key letter, lock core keyhole shape and bolt plate, wherein key letter adopts sheet, and in conjunction with the shelves limit of hyoplastron, makes its work more stable, the simplification of key letter structure also makes the lock core keyhole simple in structure, is easier to processing.
