Abstract

A dialing wheel coded lock takes four dialing wheels of 5, 6, 3, 8 in sequence as a group, holes which top is round and bottom is quadrate in the dialing wheel, forms passages with uniform rule, the passage is just inserted by a lock fork with lock fork stop, when digital of the dialing wheel is dialed to change order, the inner passage will be disturbed, the lock fork stop will block the dialing wheel inner margin, and the lock fork will not be fetched although the lock fork may be screwed, so as to reach the aim of locking. The dialing wheel outer margin is equipped with Braille, and then the blind man also may use the lock.

Description

The thumb wheel coded lock

Affiliated technical field

The utility model relates to a kind of device that just can pin bicycle, electric motor car without key.

Background technology

Present known bicycle, electric motor car Lock structure all are to utilize the principle of stirring spring, the free extension and contraction control lock of pellet shot from a slingshot fork by key, reach the purpose of " lock ".Have key just porose, and the burglar is all-pervasive exactly, causes a lot of cars stolen, and the band key is trouble, key loss, breakage, stolen bitting again, trouble especially.

Summary of the invention

Must use many troubles of key for fear of having lockset now, the potential safety hazard of avoiding keyhole to bring, the utility model provides a kind of " thumb wheel coded lock ".

The technical method that its technical problem that solves the utility model adopts is: the wheel that makes the coin-size pie with the material that certain degree of hardness is arranged.The hole of circular upper part and square lower part is worn at the wheel center.With wheel thickness is the outer rim of face, engraves 0 to 9 numeral.Make the lock fork with the straight material that certain degree of hardness is arranged, the rugosity of lock fork is as the criterion just to pass the middle circle of thumb wheel, and lock is stuck 4 lock forks of parallel welding shelves, locks the fork shelves and is as the criterion with the square hole that can just pass the circular upper part and square lower part hole in the thumb wheel.In the tapered end that 4 wheels of lock fork reeve are existed side by side, leave certain interval between the two-wheeled, be as the criterion just to put lock fork shelves into.Wheel is outer to be bright and clean hard pipe, unlikely at random in order to control 4 wheels.4 seams are opened in the position of corresponding wheel on the pipe, after the lock fork injects tapered end, suppose that the numeral on the wheel is 5,6,3,8 in regular turn, when stirring wheel and change digital order, the inner channel rule also is changed, though the lock fork can be twisted, lock fork shelves are blocked and can't take out by interior circle, tapered end connects with soft or hard material with shank of the key, reaches the purpose of " lock ".

Description of drawings

Below in conjunction with accompanying drawing and example the utility model is further specified.

Fig. 1 is the thumb wheel front, and there is the hole of circular upper part and square lower part the centre.

Fig. 2 be with the wheel thickness be on the outer rim on plane, be carved with numeral, as the usefulness that password is set.

Fig. 3 is the lock fork of fork shelves with lock.

Fig. 4 is that the lock fork injects 4 thumb wheels of existing side by side.

Fig. 5 is the bright and clean hard pipe of the outer preparation of thumb wheel, and is connected with soft or hard material between the lock fork handle, forms complete lock, and the seam that corresponding thumb wheel place opens on the pipe is as the usefulness of group password.

The specific embodiment

When lock fork injected tapered end, lock fork shelves just passed through in the square hole in the trailing wheel.This moment, numeric sorting was 5,6,3,8, and when thumb wheel rotated the change order, the inner channel rule also changed thereupon, though the lock fork handle is rotatable, can't take out, and reached the purpose of " lock ".

Claims (1)

1, a kind of thumb wheel coded lock is characterized in that: with 5,6,3,8 is that 4 thumb wheels of order are one group and exist side by side, and the hole of the circular upper part and square lower part in the thumb wheel forms the passage of uniform rules, and the lock fork that just holds fork shelves with lock injects, and the thumb wheel outer rim engraves braille.
