Description

Code memory built-in lock

The utility model relates to light industrial products hardware ﹠ tools class, the lock of usefulness such as particularly a kind of door, case, cabinet, cupboard and bag.

The kind of lock is more.Existing mechanical lock, electronic lock all include lock body, frame for movement and key.Also useful coding of electronic lock or magnetic card.Though they all have the proper function of lock, their common drawback are that lock body exposes easily by others' picking lock; Key loss is difficult for joining; Key is found by others or is encoded and known by others, unblanks easily; Complex structure, the cost height.

The purpose of this utility model is to provide a kind of lock body not expose, and is simple in structure, the stealthy lock of note sign indicating number that others can't know of encoding.

The utility model is realized by following measures: it is a kind of door, case, cabinet, the lock of usefulness such as cupboard and bag, it includes key, the cavity lock body, rivet, iron staff, fill out rod, copper wire, their assembly relations are that lock body (1) (2) is contained in the body, lock body (3) (4) is contained in the door body, lock body (2) lock body (3) position can exchange, the end and the lock body (2) that are built-in with the iron staff (8) of the parallel shop front rotation of energy at lock body (1) (2) flexibly connect by rivet (7), lock body (6) is contained in the body, lock body (6) is contained in the body, lock body (5) is contained in the door body, lock body (5) is corresponding mutually on same horizon with lock body (6), movably iron staff (11) places in lock body (5) and the lock body (6), be equipped with in lock body (5) cavity and fill out rod (10), also can be contained in lock body (6) cavity as required filling out rod (10), copper wire (12) with fill out rod (10) fixedly connected by copper wire (12) can will fill out rod (10) take out.The principle of lock is that fixed end just rotates in the lock body (3) from lock body (2) iron staff (8) by rotating not, forms locking.For strengthening the degree of lock, movably iron staff (11) is housed in the lock body (5) (6), iron staff moves to lock body (2) and lock body (3) intersection forms locking.Do not learnt in order to lock a door by other people, available many group lock bodies (5) (6), variable along door and doorframe upper-lower position, variable, the direction-agile of quantity, the number of turns, the direction of iron staff (8) rotation are also variable, thereby can form up to a million codings, just can as long as remember coding when locking a door, in case others knows coding, the owner of lock can change coding at any time.The key of opening or locking according to coding is a magnet, and it is without any structure, and general magnet gets final product.

The utility model compared with prior art has following beneficial effect: the body of (1) lock does not expose, and this is because lock is to be contained in a body and the doorframe, so lock is stealthy; (2) key of stealthy lock, promptly magnet is lost, and can join again, and the thief picks up and can't unblank, because he does not know the coding locked; (3) Suo code change is infinite.Mechanical lock, electronic lock coding are known by other people, just unblank easily, and the coding of this lock are known and can be changed at any time by the owner of lock by others; (4) cost simple in structure is low.Traditional mechanical lock, electronic lock structure complexity are made difficulty, and the cost costliness is repaired difficulty, and bitting is difficulty also, and this lock construction is simple, and cost is low, can manual production, do not need main equipment, and be fit to township enterprise, the self-employed worker produces.

Description of drawings

Accompanying drawing is the structural representation of the stealthy lock of note sign indicating number.

Now in conjunction with the accompanying drawings the utility model is further described, lock body (1) (2) (3) (4) is that the cavity nonmagnetic substance is made, lock body (1) (2) is contained in the body, lock body (3) (4) is contained in the door body, the parallel correspondence of lock body (1) (2) (3) (4), the available cottor pin of iron staff (8) replaces, it and lock body (2) flexibly connect by universal rivet (7), iron staff when locking a door (8) rotates a few and gets final product, iron staff (8) is contained in the lock body (1) (2) (3) (4), and can do the rotation round motion, lock body (5) (6) is to make with nonmagnetic substance, fill out the little pole of available bamboo of rod (10) or wooden one-tenth, diameter is slightly less than lock body (5) (6) cavity interior diameter, fill out and be fixed with copper wire (12) on the rod (10), in order to moving of restriction iron staff (11), filling out rod (10) can be contained in lock body (5) cavity, also can be contained in lock body (6) cavity, iron staff (11) moves in lock body (5) (6) cavity, it is moving toward backward shift by copper wire (12) filling out rod (10), when iron staff (11) moves in lock body (5), lock body (6) junction, with regard to lock door.For the intensity of locking, it is right that lock body (5) (6) can be adorned 1-10, and the stealthy locking of note sign indicating number becomes like this.

Claims (2)
