The utility model uses the inner pin 5 insert or not insert into the outer ring 2, makes the outer ring 2 and the inner ring 3 connectedly move or not connectedly move, thereby realizing the operation of engaging and disengaging of the lock.

Description

The arrangement of clutch of lock

Technical field

The utility model relates to a kind of component of lock, particularly a kind of arrangement of clutch of lock.

Background technology

At present, the arrangement of clutch of the employed lock of people is varied.

Summary of the invention

The purpose of this utility model provides a kind of arrangement of clutch that utilizes the effect realization separate or merge operation of spring, and simple in structure, easy to use, cost of production is low.

In order to achieve the above object, the technical solution of the utility model is as follows:

A kind of arrangement of clutch of lock comprises shell 1, outer ring 2, inner ring 3, spring 4, sold inside the country 5, steel ball 6, export trade 7; Outer ring 2 places in the shell 1, and outer ring 2 is enclosed within on the inner ring 3, and the three is coaxial; But outer ring 2 opposite shell 1 are rotated, between outer ring 2 and the inner ring 3 both separate can not interlock; Inner ring 3 radially is provided with a hole 8, and sold inside the country 5 activities are contained in the hole 8, sold inside the country 5 and the bottom in hole 8 between spring 4 is housed; Radially be provided with a hole 9 of running through outer ring 2 corresponding to the position in hole 8 on the outer ring 2, mobilizable steel ball 6 is housed in the hole 9; Radially also be provided with a hole 10 of running through shell 1 corresponding to the position in hole 9 on the shell 1, export trade 7 activities are contained in the hole 10 and offset with steel ball 6.

In preferred version of the present utility model, steel ball 6 is spherical, and size matches with hole 10.

Described export trade 7 is T-shaped, inner small and outside big.

Described sold inside the country 5, export trade 7 is equipped with lead angle with the end face that is connected of steel ball 6.

Owing to adopted said structure, utilize sold inside the country 5 to insert or do not insert outer ring 2, make outer ring 2 and inner ring 3 interlocks or interlock not, thus realized lock close with from operation.

Description of drawings

Fig. 1 is the utility model overall structure schematic diagram;

Fig. 2 is the utility model released state sectional drawing;

Fig. 3 is the utility model engagement state sectional drawing.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail:

Steel ball 6 is spherical, and size matches with hole 10, is convenient to enter hole 10.

Export trade 7 is T-shaped, and is inner small and outside big, limits the inside moving position of export trade 7.

Sold inside the country 5, export trade 7 is equipped with lead angle with the end face that is connected of steel ball 6, guarantees the reliable separation of outer ring 2 and inner ring 3.

As shown in Figure 2, export trade 7 upwards promotes steel ball 6 and is sold inside the country 5, and compression spring 4, and sold inside the country 5 are pushed in the inner ring 3 fully, and 6 of steel balls at this moment, do not have moving part between outer ring 2 and the inner ring 3 in outer ring 2, and arrangement of clutch is in released state.

As shown in Figure 3, export trade 7 moves downward, under the elastic force effect of spring 4, sold inside the country 5 and steel ball 6 also move downward, sold inside the country 5 simultaneously part insert in the outer ring 2, outer ring 2 and inner ring 3 link together by sold inside the country 5, this moment, arrangement of clutch was in engagement state.
