Abstract

The utility model relates to a spring lock for a bicycle, comprising three parts of a thin lock core body, a rough lock core body and an up-down key, which is characterized in that a hole of the thin lock core body is opened on the thin lock core body shaped like the Chinese character <ding> with a thin lock core marble arranged; a hole of the rough lock core body is opened on the rough lock core body hollowed and shaped like the Chinese character <ding> with a rough lock core marble arranged. An inner diameter is arranged in the rough lock core body to match with a slide of an outer diameter of the thin lock core body. By jointing with the rough and the thin lock core bodies, the lock core body through a bicycle frame can lock the bicycle frame, namely, a wheel in the bicycle frame. With the above technology proposal adopted, the lock has changed the design of common lockset which is characterized by a simple structure, safety and reliability, and a special and excellent lockset design.

Description

A kind of safety spring lock

Affiliated technical field

The utility model relates to a kind of latch lock of locking bicycle.

Background technology

At present, the lockset of bicycle is from keyhole and inserts key, and its shortcoming is easily to insert the unlocking tool of opening this lock from keyhole, is easy to reach the purpose of stealing this bicycle, causing the Loss Rate of bicycle high always, also is not highly effective solution at present.

Summary of the invention

In order to overcome the shortcoming of present bicycle lock, the utility model provides a kind of safety spring lock, and it has thoroughly changed the design of general lockset, and this latch lock has simple in structure, safe and reliable characteristic, is a kind of original in style lockset.The technical scheme that its technical problem that solves the utility model adopts is: this lock comprises thin lock core body (2), thick lock core body (3) and upper and lower key (6), (8) three parts, it is characterized in that: on the thin lock core body (2) of nail font, have thin lock core hole (4), thin lock core marble (13) is installed in the hole; On the thick lock core body of tee T (3) of hollow type, have coarser lock cylinder hole (5), coarser lock cylinder marble (12) is housed in this hole, in thick lock core body (3) body, vertically have the internal diameter of a hollow, its internal diameter is installed with the external diameter sliding fit of thin lock core body (2), by the butt joint of thick, thin lock core body (3), (2), lock core body passes vehicle frame (10), can pin the wheel in the vehicle frame (10).

Its beneficial effect is: owing to adopted technique scheme, this lock has thoroughly changed the design of general lockset, has simple in structure, safe and reliable characteristic, is a kind of original in style superior lockset design.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Accompanying drawing is the structure of the present utility model and the schematic diagram of unblanking.

Among the figure, the 1. thin lock core body of displacement, 2. thin lock core body, 3. thick lock core body, 4. thin lock core hole, 5. coarser lock cylinder hole is 6. gone up key, and 7. key in the displacement 8. plays key, 9. key under the displacement, 10. vehicle frame, the thick lock core body of 11. displacements, 12. coarser lock cylinder marbles, 13. thin lock core marbles.

The specific embodiment

In the drawings, the pellet shot from a slingshot that is installed in the thick pin core hole (5) is an independently pellet shot from a slingshot that varies in size, and this pellet shot from a slingshot external diameter is less than the internal diameter of coarser lock cylinder hole (5), and what it was slidingly matched is installed in the coarser lock cylinder hole (5).

In the drawings, the thin lock core marble (13) that is slidingly installed in thin lock core hole (4) is a pair of combination pellet shot from a slingshot, and tension spring is installed between two pellets shot from a slingshot, and this spring can be released thin lockhole to pellet shot from a slingshot.

In the drawings, solid line chart is after coarser lock cylinder hole (5) is inserted in upper and lower key (6), (8), slightly, thin core pellet shot from a slingshot (12), (13) all enter slightly, in the thin lock core body (3), (2), thick, thin lock core touching position keeps level and smooth, gets final product the schematic diagram that a lock is opened.If key is taken away, thick, thin core pellet shot from a slingshot (12), (13) promptly can be locked thick, thin lock core (3), (2).

In the drawings, open thick, the thin lock core hole (5) on thick, thin lock core body (3), (2), the number of (4), be respectively 2-10.
