The specific embodiment

Specific embodiment 1

As Fig. 1, upper cover plate 10 be a rectangle its double regular circular hole is arranged, circular hole is link to each other up and down the vertical column hook guide channel and the unlatching knob of the corresponding support of equivalent, be used for fixing and guide the activity of the button extension arm of force, upper cover plate 10 usefulness screws and carrier base top are fixed, button 2 is touched by a post clasp joint and prolongs a cylinder arm of force and downward of slightly being longer than post hook stroke on the platform and stablize inserted link and form, its post clasp joint touches the platform girth and is slightly larger than extension arm of force girth, skewer advances in the carrier base after stablizing the skewer bar and being inserted in return spring, support and recoiled to the initialization position to guarantee that button pressed post hook enters to lose behind the predetermined card link plate, locking bolt 5 is the cuboid of the horizontal protruding flat tooth 13 of a vertical band, its recessed time part under the lockset closure state over against two side columns hook vertical side, be beneficial to working up and down of post hook, the front end of locking bolt is the dead bolt that locks with snap close, its hand hay cutter face of opening knob 16 in correspondence is provided with vertical tooth rack 17, be beneficial to open travelling gear 15 when locking bolt machinery passage is opened, drive the locking bolt retraction and open lockset, the rear end extension rod of locking bolt is with return spring 7, when opening the disappearance of knob active force, the locking bolt sinciput is entered working up and down of locking that closed duty is beneficial to lockset and post hook, and when not making lock operation, locking bolt machinery passage still is in opening state, repeats to open the operation of knob 16 and still can open lockset.When pressing removing post hook 3 or anti-guard post hook, locking bolt is stuck, so that can't bounce back, thereby reaches the purpose of locking.Post hook 4 is by different length but is equal to corresponding square column with card hanger plate height at different levels that vertical with locking bolt one side, post briar tooth 21 less than 45 degree, is one-level or secondary or three grades or level Four greater than 30 degree, abbreviates monodentate hook, bidentate hook and multiple tooth hook as.The working method of monodentate post hook is a simple tooth either-or pattern to a card, password very easily is cracked, poor stability, the post hook 4 of the embodiment of the invention has adopted the bidentate hook, they both can a pair of two combination pins, also can two pairs two stride a layer combination pin, password is counted the permutation and combination amount: the computational methods that single deck tape-recorder is hung

A_{mx}^{n} = \frac{m!}{(m - n)!}

Many cards are hung the computational methods of the group amount of password

A_{mx}^{n} = \frac{mx!}{(mx - n)!}

Wherein A is the cipher code set amount, m is the button summation, x is the number of card hanger plate, n selects the number of password key for row, on the input mode just in the mating reaction of multiple tooth post hook and multilayer card hanger plate, the succession input of itself and prior art relatively, non-succession input service mode and hidden input mode have been increased, particularly in multiple tooth mode of operation to many cards, in case multiple tooth anti-guard post hook be pushed under the multilayer card extension state, if adopt the clear operation of certain single-stage, non-lockset owner can't return to it initial operating position, even by correct password input operation, the mechanical passage of locking bolt is still blocked again, lockset still can't be opened.After various posts were hooked in the correct input operation of process, all post hook side shallow ridges 18 all entered the parallel position of locking bolt 5, and mechanical passage is opened, and contract knob drive locking bolt after by opening this moment, and dead bolt 6 breaks away from snap closes 20, and the work of unblanking is finished.

Specific embodiment 2:

Present embodiment adopts the input mode of multiple tooth post hook, both can adopt the big angle to arrive the order input at little angle, the mode that also can adopt the identical back of front end tooth angle tooth angle degree to change is carried out, but multistage or stride the layer post hook input mode in, its grade can freely be selected with the tooth angle of level, purpose is to make the stranger can't find out the function or which grade use of post hook, and it just can't know the number and the arrangement of password.

According to password number and the requirement of cipher code set amount, the post hook use amount of various performances can be provided with as requested, this routine hanger plate is made up of the first card hanger plate 8 and the second card hanger plate 9, they all are that one rectangular shape of cross is dull and stereotyped in length and breadth forms, and its horizontal support body and post clasp joint touch and the post hooks that the have 45 degree stress when introducing inclined-planes 14 and advancing the card hanger plate in order to minimizing post hook.Two blocks of grab plates leave the spacing highly corresponding with single-stage post hook briar tooth 21, every card fore-and-aft plane of hanger plate and post hook over against an end return spring 7 is housed, with independence and the stable extension of post hook that guarantees the work of every card hanger plate, the characteristics of multilayer card hanger plate are when the post hook 4 of different length is pushed into the operating position, it is hung on first card hanger plate 8 and on second hanger plate 9 by card respectively, but the inwhole parallel operating positions of its post hook side shallow ridges 18 at locking bolt 5, the machinery passage is not opened, when importing password by correct group code, also need to press the first order or the second level and remove the post hook, then first or second is blocked hanger plate is promptly blocked extension by pushing away post hook, striding the level or the post of corresponding single-stage is hooked under the effect of its bottom spring and enters on predetermined another grade card hanger plate, when being provided with two predetermined clip pin post hooks, also need heavily to enter the second card hanger plate by the post hook, thereby increase the function of keeping secret of one-level or secondary password, password hidden input in the removing that seems operate miss of this group at this moment, the side shallow ridges 18 of this group post hook is just in time parallel with locking bolt 5, the mechanical passage of this group is opened, correctly import another grade group code then, the machinery passage is all opened when parallel with the locking bolt 5 all operating position of post hook side shallow ridges, and locking bolt just is able to smoothly retraction and opens lockset.The unlatching knob 16 of this example is to form together with the extension bar with locking bolt side direction travelling gear 15, and its effect is to drive locking bolt 5 retraction disengaging snap closes to reach purpose of opening when post hook machinery passage is opened, in case its active force disappears, locking bolt is promptly pushed up go back to the initialization position.This routine carrier base mainly is divided into locking bolt workspace, top and bottom card hanger plate putting groove.The locking bolt workspace is a vertical flat-bottom slot a little less than key stroke, the down either side of groove has the vertical column hook gathering sill of corresponding locking bolt side direction recess, its effect is to make the post hook can normally hang into or withdraw from the card hanger plate, the rear end of set bar groove is locking bolt return spring storehouse, the bottom be in the branch card hanger plate putting groove of vertical both sides horizontal stroke, the post hook gathering sill equivalent that side direction branch groove and upper vertical are downward and corresponding, a middle cannelure end corresponding with the post hook has two-layer card hanger plate return spring storehouse, the card hanger plate at carrier base rear portion needs balance briquetting 19 fixing, it is matrix metal derby or unit of plastic, the corresponding hanger plate of its side direction position has parallel groove, card hanger plate lateral cuboid is snapped in wherein, the balance that keeps its work, when the installation of post hook, its front end return spring also needs to press firm fixed, ability force of labor Hui Li, therefore need lower cover 11 to finish, the corresponding carrier base of its size bottom.
