Abstract

A chain-type soft lock with flexible keys is mainly characterized in that a key groove hole (6) on a lock cylinder (2) is curved; the lock cylinder (2) is directly embedded into a lock head (1); bullet ball holes are arranged right above the corresponding key groove hole (6); the bullet ball holes are positioned with springs (7), upper bullet balls (8) and lower bullet balls (9); the top of the lower bullet balls (9) matches with a chain-type key (4); inside the bullet ball holes, a flexible key mechanism is arranged; the flexible key mechanism mainly comprises steel balls (11); the steel balls (11) are positioned between the upper bullet balls (8) and the lower bullet balls (9); steel ball holes (12) are arranged on the surface of the lock cylinder (2) in the same cross section with the steel balls (11). The utility model can simplify connecting structure between the lock head and the lock cylinder; the added flexible key mechanism can make the whole lock have advantages of simple structure, much smaller volume and weight, as well as improved safety and privacy.

Description

Chain type software conversion locking cam

1, technical field:

The utility model relates to a kind of tapered end, relates in particular to chain type software conversion locking cam.

2, background technology:

At present, most tapered end on the market all adopts common key operated, keyhole is a straight trough, key is replicated easily, tapered end is opened easily and is pried open, a kind of chain type software lock has also appearred on the market in addition, for example the patent No. is 90206770, and notification number is 2069457 utility model patent, and its key is that chain type can be crooked, the key groove hole of lock core the inside also is crooked, but this lock complicated integral structure, tapered end and lock core by several other parts mutually nested together, volume is bigger, relatively heavier, cause range of application to be subjected to certain restriction.

3, summary of the invention:

The purpose of this utility model provides a kind of chain type software conversion locking cam, and it improves on original chain tapered end basis, simplifies the syndeton of tapered end and lock core, increase the conversion key mechanism, make whole lock head structure simple, volume, weight are dwindled greatly, and level security is improved.

The utility model is achieved by the following technical solution: it comprises tapered end, lock core, driver blade and software key assembly, software key assembly comprises chain spoon and spoon root spare, wherein the key groove hole of lock core is crooked, lock core directly is nested in the inside of tapered end, the position of corresponding key groove hole is provided with the hoodle hole, the inside, hoodle hole is equipped with spring, last hoodle and lower pellet, the top of lower pellet cooperates with tartar on the chain spoon, the inside, a hoodle hole is provided with conversion spoon mechanism therein, this conversion spoon mechanism mainly comprises steel ball, steel ball is installed between hoodle and the lower pellet, and the plug face that is positioned on the same cross section with steel ball is provided with the steel ball hole.

All be provided with the anti-plug gathering sill on key prerotation vane in the middle of the above-mentioned described lock core, partition, the pellet shot from a slingshot supporting slice, the anti-plug gathering sill is corresponding with the key groove hole position.

The utility model compared with prior art has following advantage: 1, adopt the chain type key, the key groove hole of tapered end the inside lock core is crooked, key configuration difficulty, theftproof performance is good, increases conversion spoon mechanism, makes product meet user's requirement more, a lock often has several keys, wherein key be when using for the first time just effectively, can not open tapered end more later on, other several keys then can be opened; 2, simple and reasonable, volume is less, and is in light weight, good looking appearance, and price is low; 3, all be provided with the anti-plug gathering sill on key prerotation vane, partition, the pellet shot from a slingshot supporting slice, the anti-pick-proof of dialling increases the tapered end safety.

4, description of drawings:

Below in conjunction with accompanying drawing the utility model is done detailed explanation:

Fig. 1 is a structural front view of the present utility model;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the B-B sectional view of Fig. 2;

Fig. 4 is the structural representation of the utility model software key assembly;

Fig. 5 is the structural representation of the utility model key prerotation vane.

5, the specific embodiment:

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model comprises tapered end (1), lock core (2), driver blade (3) and software key assembly, software key assembly comprises chain spoon (4) and spoon root spare (5), wherein the key groove hole (6) of lock core (2) is crooked, lock core (2) directly is nested in the inside of tapered end (1), directly over the position of corresponding key groove hole (6), be provided with the hoodle hole, the inside, hoodle hole is equipped with spring (7), last hoodle (8) and lower pellet (9), the top of lower pellet (9) cooperates with tartar (10) on the chain spoon (4), the inside, a hoodle hole is provided with conversion spoon mechanism therein, this conversion spoon mechanism mainly comprises steel ball (11), steel ball (11) is installed between hoodle (8) and the lower pellet (9), and lock core (2) surface that is positioned on the same cross section with steel ball (11) is provided with steel ball hole (12).Be installed on the middle key prerotation vane (13) of lock core (2), partition (14), the pellet shot from a slingshot supporting slice (15) and all be provided with anti-plug gathering sill (16), anti-plug gathering sill (16) is corresponding with key groove hole (6) position, as shown in Figure 5.

Software key assembly comprises chain spoon (4) and spoon root spare (5), and spoon root spare (5) is made up of push rod (17) and housing (18), housing (18) is hollow, one side is provided with chute (19), and the bottom of push rod (17) is embedded into the inside of chute (19) and is connected the root of chain spoon (4).Promote push rod (17) when left, push rod (17) drives chain spoon (4) retraction housing (18).Promote push rod (17) to the right and just chain spoon (4) can be stretched out housing (18).

The main effect of conversion spoon mechanism is to make product meet user's requirement more, a lock often has several keys, wherein key be when using for the first time just effectively, can not open tapered end more later on, and in addition several keys to use for the first time be not have effectively, competence exertion effect after above-mentioned nonrecoverable key is opened tapered end, like this purpose of She Zhiing be when the user after finishing is during new house, for fear of being taken the key configure by others.Its operating principle is as follows: when opening tapered end for the first time, make the steel ball (11) of one of them the inside, hoodle hole enter the inside, steel ball hole (12), the differential of this hoodle hole changed, the hoodle of the height of the tartar (10) on the therefore original chain spoon (4) and the inside, this hoodle hole does not just match, and causes and can not open.
