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 effect realization separation of spring and arrangement of clutch of bonding operation of utilizing, 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, A rotating shaft 2, B rotating shaft 3, back-moving spring 4, executive module 5, drive pin 6; 21 cambered surfaces of A rotating shaft 2 match with shell 1 inner ring, and 22 cambered surfaces of A rotating shaft 2 match with B rotating shaft 3, and shell 1, A rotating shaft 2 and B rotating shaft 3 threes are coaxial; But A rotating shaft 2 opposite shell 1 are rotated, between A rotating shaft 2 and the B rotating shaft 3 both separate can not interlock; B rotating shaft 3 radially is provided with a hole 7, and executive module 5 activities are contained in the hole 7, and matches with the shape in hole 7, and back-moving spring 4 places between B rotating shaft 3 and the executive module 5; Radially be provided with a hole 8 of running through A rotating shaft 2 corresponding to the position in hole 7 in the A rotating shaft 2; Shell 1 radially is respectively equipped with hole 9 and hole 10 corresponding to the position in hole 8 and hole 7, and drive pin 7 activities are contained in the hole 10 and offset with executive module 5.

Described executive module 5 is formed by carrying out pin 51, counterbalance spring 52 and compensation pin 53, carries out pin 51 and compensation and sells 53 and match with the shape in hole 7.Compensation pin 53 has an endoporus 11, and hole 11 is a stairstepping, and counterbalance spring 52 places between the bottom of carrying out pin 51 and hole 11.

Described hole 7 is three grades of stairsteppings.

The upper surface of the connection end face of described drive pin 6, compensation pin 53 and execution pin 51 is equipped with lead angle, and 23 end faces of A rotating shaft 2 are the inclined-plane.

Owing to adopted said structure, utilize the execution pin 51 of executive module 5 to insert or do not insert A rotating shaft 2, make between A rotating shaft 2 and the B rotating shaft 3 interlock or interlock not, thus realized lock close and from operation.

The specific embodiment

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

Executive module 5 is formed by carrying out pin 51, counterbalance spring 52 and compensation pin 53, carries out pin 51 and compensation and sells 53 and match with the shape in hole 7.Compensation pin 53 has an endoporus 11, and hole 11 be a stairstepping, with restriction carry out pin 51 to top offset, counterbalance spring 52 place carry out sell 51 and the bottom in hole 11 between.

Hole 7 is three grades of stairsteppings, can limit counterbalance spring 52, carries out pin 51, compensate and sell 53 upwards moving position.

The upper surface of the connection end face of drive pin 6, compensation pin 53 and execution pin 51 is equipped with lead angle, and 23 end faces of A rotating shaft 2 are the inclined-plane, guarantees reliable separation between A rotating shaft 2 and the A rotating shaft 3.

As shown in Figure 3, drive pin 7 upwards promotes executive module 5, executive module 5 compression reseting springs 4, carry out pin 51 upper ends and pushed fully in the A rotating shaft 2, at this moment, connect by carrying out pin 51 between A rotating shaft 2 and the B rotating shaft 3, arrangement of clutch is in engagement state, mutually interlock.

As shown in Figure 4, drive pin 7 moves downward, and under the restoring force effect of back-moving spring 4, executive module 5 also moves downward, and execution pin 51 moves down and breaks away from A rotating shaft 2, does not have moving part between A rotating shaft 2 and the B rotating shaft 3, and this moment, arrangement of clutch was in released state.

As shown in Figure 5, if in A rotating shaft 2 and B rotating shaft 3 motion processes, hole 8 also is in the off normal state with hole 7, when drive pin 6 upwards promotes, 22 or 23 end faces of carrying out pin 51 and A rotating shaft 2 offset, counterbalance spring 52 is compressed, when the hole 8 of A rotating shaft 2 rotate to corresponding with hole 7, counterbalance spring 52 resiliences, carry out pin 51 patchhole 8 thereupon, connect by carrying out pin 5 between A rotating shaft 2 and the B rotating shaft 3, arrangement of clutch is in engagement state, mutually interlock.
