Description

Theft-proof puzzle lock

The utility model belongs to the lock class, particularly relates to a kind of coded lock.

Existing coded lock, often exist can be only with feel and the sense of hearing with regard to openable shortcoming, can not be effectively antitheft.In addition, when having the gap between cipher wheel, can watch out the position of password, the deficiency of above-mentioned several respects has caused the coded lock safety factor low, can not protect the people's property effectively.

The purpose of this utility model be to provide a kind of can not the armrest sense and the sense of hearing is opened, the anti-theft puzzle lock of vi have high safety.

Its technical scheme is: a kind of coded lock, comprise lock body 1, locking bolt 2, be sleeved on the cipher wheel 4 on the password bolt 3, dark pellet shot from a slingshot 5, of the present utility model being characterised in that: it comprises that also one is positioned at the angle code wheel 6 of password bolt 3 ends, there is a flange 9 at place, cipher wheel 4 inwall middle sections, and a groove 10 is arranged on the flange 9.

Because the utility model has been set up the angle code wheel, even its effect is cipher wheel position total correctness, code wheel position, angle is not right, and therefore the lock of also not opening more improves safety factor.Because the flange on the inwall of garble wheel is located at the place, middle section; The one, prevent that the stranger from finding out the position of password groove when between cipher wheel, having the gap, the 2nd, dark pellet shot from a slingshot rotates on smooth flange, can not send the sound and produce vibrations, therefore can not open coded lock with the feel and the sense of hearing.

Further specify the utility model below in conjunction with accompanying drawing and by embodiment.

Fig. 2 is the structural representation of cipher wheel;

Fig. 3 is the password bolt cross-sectional view of embodiment 1;

Fig. 4 is the complete section structural representation of embodiment 2;

Fig. 5 is the complete section structural representation of embodiment 3;

Fig. 6 is the complete section structural representation of embodiment 4.

Embodiment 1: as shown in Figure 1, there is one jiao of code wheel 6 end of password bolt 3, in order to save material, takes nested form, and with pinning 11 pin joints.Cipher wheel 4 is sleeved on the password bolt 3, and as shown in Figure 2, there is a flange 9 at the place along garble wheel 8 inwall middle sections, and a groove 10 is arranged on the flange 9.As shown in Figure 3, dark pellet shot from a slingshot 5 is inlaid in the password bolt 3, and all dark pellets shot from a slingshot in a straight line.One hole 12 is arranged in lock body 1, be equipped with in the hole 12 and move back bolt pellet shot from a slingshot 13, a hole 14 is also arranged on the password bolt 3, three circular holes 15 and two installing holes 16 are arranged on lock body 1.

Present embodiment is mainly used in the antitheft of tractor with small four wheels.Tractor with small four wheels is when the reverse gear state, and the gearbox left side has three fork shaft extensions to go out, and the centre is a reverse gear fork axle, and all there is a groove end of each declutch shift shaft.This practical example is installed in the gearbox left side with it in use.Coded lock is placed open mode, the declutch shift shaft in gearbox left side is put in the hole 15, the groove of reverse speed fork shaft end is just blocked in password bolt 3 ends, upset password again the lock locking, at this moment just can't engage a gear, play antitheft effect, here, declutch shift shaft serves as the effect of locking bolt.

When need are driven, can forward cipher wheel and angle code wheel to correct position by setting code, password bolt 3 is extracted out engage a gear operation again.For can the conversion password: the standby cipher wheel supporting with coded lock arranged, when need conversion password, make hole 12 on the lock body and the hole 14 on the password bolt in line, put in the hole 12 with a fine needle, bolt pellet shot from a slingshot 13 is moved back in compressing, and password bolt 3 can be withdrawed from, and takes off cipher wheel then, change standby cipher wheel, promptly convertible password.

Embodiment 2: the represented meaning of parts identical with label among the embodiment 1 and act on identical in the present embodiment.In the present embodiment, as shown in Figure 4, one hole 17 is arranged in addition, pillar 18 and steel ball 19 are housed in the hole 17 near 12 places, hole.When locking states, steel ball 19 chucking locking bolts 2.To behind the good password, password bolt 3 is outwards extracted out a little during unlatching, steel ball 19 and pillar 18 drop in the groove 20 on the password bolt together, and locking bolt 2 flicks under the effect of spring 21, and lock is promptly opened.

When making locking bolt 2 directly pinned the hanging noses on the door.

Embodiment 3: present embodiment is mainly used in motorcycle and motor tricycle, is installed on the front fork of car, and rotate in order to make locking bolt 2 back of unblanking, and is provided with shell of revolution 22 and rotation nail 23.All the other label titles and effect thereof are identical with embodiment 1.

Embodiment 4: present embodiment is used for bicycle, can be installed on the front fork or back vent of bicycle.Two holes 24 are arranged on lock body 1, will lock 2 groups of the locking bolts in unlatching back and get off to be inserted in the hole 24, the title of all the other labels and effect thereof are identical with embodiment 1.

The structure of embodiment 2,3,4 cipher wheel is identical with embodiment 1 with the method for conversion password.
