Description
Technical field
The utility model provides a kind of plugging handlebar mechanism, belongs to drive technology field, more particularly to a kind of logical
Cross manual operation and realize power output shaft one direction for power output, the handlebar mechanism that opposite direction can be braked automatically.
Background technology
Handlebar mechanism has been widely used in hand operating mechanism field, and usual handlebar mechanism is capable of achieving suitable by manpower
Hour hands and rotation counterclockwise, but, handlebar mechanism does not have braking action in the clockwise or counterclockwise direction.If behaviour
Braking is needed as system, independent outfit brakes is needed, brake response is slow, and braking procedure is relatively complicated.
Utility model content
In order to overcome the shortcomings of that prior art is present, the utility model provides a kind of new, reliable crank and reverses system
Motivation structure, with the function that unidirectional power output, opposite direction are braked.
The utility model is achieved by the following technical programs.
A kind of plugging handlebar mechanism, it includes handwheel, housing and power transmission shaft, it is characterised in that：Arrange through housing
There is power transmission shaft, power transmission shaft one end end is installed with handwheel, and the power transmission shaft other end is provided with end cap；The power transmission shaft two ends with
Housing contact position is provided with bearing, is located on power transmission shaft between the bearing of both sides and is fixedly installed mono-directional overrun clutch, described
Mono-directional overrun clutch includes inner ring and outer ring, and inner ring is fixedly installed on power transmission shaft, and enclosure interior is located at mono-directional overrun clutch
Drag housing is fixedly installed outside device, the drag housing includes thin oral area and wide-mouth portion, and thin mouth inner wall is fixedly installed in unidirectional super
More in clutch outer, wide mouth inner wall is provided with brake shoe, and when drag housing rotates, brake shoe brakes drag housing.
Further, the handwheel is fixedly connected by key with the power transmission shaft.
Further, the power transmission shaft is fixedly connected by key with mono-directional overrun clutch inner ring, and power transmission shaft is square clockwise
When rotation, mono-directional overrun clutch inner ring is transferred outer ring and is not turned；During power transmission shaft counterclockwise rotates, mono-directional overrun clutch
Inner ring turns and drives outer ring synchronous axial system.
Further, the mono-directional overrun clutch outer ring is fixedly connected by key with the thin mouth inner wall of the drag housing.
The utility model has the advantages that compared with prior art.
A kind of plugging handlebar mechanism that the utility model is provided, is capable of achieving unidirectional power output, and opposite direction is certainly
Dynamic to realize braking, with safe reverse-rotation preventing function, and handlebar mechanism is simple for structure compact, easy for installation.
Description of the drawings
Fig. 1 is the utility model overall structure cross-sectional schematic.
In figure, 1 is handwheel, and 2 is power transmission shaft, and 3 is bearing, and 4 is mono-directional overrun clutch, and 5 is drag housing, and 6 is brake shoe,
7 is housing.
Specific embodiment
The utility model is elaborated with reference to embodiment, the present embodiment is with technical solutions of the utility model
Premised under implemented, give detailed embodiment and specific operating process, but protection domain of the present utility model
It is not limited to following embodiments.
A kind of plugging handlebar mechanism, it includes handwheel 1, housing 7 and power transmission shaft 2, it is characterised in that：Through housing 7
Power transmission shaft 2 is provided with, one end end of power transmission shaft 2 is installed with handwheel 1, and the other end of power transmission shaft 2 is provided with end cap；The transmission
The two ends of axle 2 are provided with bearing 3 with the contact position of housing 7, are located on power transmission shaft 2 between both sides bearing 3 and are fixedly installed unidirectional surpassing
More clutch 4, the mono-directional overrun clutch 4 includes inner ring and outer ring, and inner ring is fixedly installed on power transmission shaft 2, inside housing 7
Drag housing 5 is fixedly installed outside mono-directional overrun clutch 4, the drag housing 5 includes thin oral area and wide-mouth portion, in thin oral area
Wall is fixedly installed on the outer ring of mono-directional overrun clutch 4, and wide mouth inner wall is provided with brake shoe 6, when drag housing 5 rotates,
Brake shoe 6 brakes drag housing 5.
Further, the handwheel 1 is fixedly connected by key with the power transmission shaft 2.
Further, the power transmission shaft 2 is fixedly connected by key with the inner ring of mono-directional overrun clutch 4, and power transmission shaft 2 is clockwise
When direction rotates, the inner ring of mono-directional overrun clutch 4 is transferred outer ring and is not turned；During 2 counterclockwise rotates of power transmission shaft, mono-directional overrun from
The inner ring of clutch 4 turns and drives outer ring synchronous axial system.
Further, the outer ring of the mono-directional overrun clutch 4 is fixed with the thin mouth inner wall of the drag housing 5 by key and is connected
Connect.
Motion process is as follows：When shake handwheel 1 is rotated clockwise, power transmission shaft 2, the inner ring edge of mono-directional overrun clutch 4 are driven
Rotationally clockwise, because the Internal and external cycle of the direction mono-directional overrun clutch 4 that turns clockwise is separated, realize power transmission shaft 2 suitable
It is conterclockwise freely to rotate；When shake handwheel 1 is rotated counterclockwise, power transmission shaft 2, the inner ring of mono-directional overrun clutch 4 are driven along inverse
Clockwise is rotated, and because the Internal and external cycle of rotate counterclockwise direction mono-directional overrun clutch 4 is combined, makes mono-directional overrun clutch 4
Drive drag housing 5 to rotate, but due to the friction braking action of brake shoe 6, cause drag housing 5, mono-directional overrun clutch 4 and transmission
Axle 2 all can not be rotated in the counterclockwise direction, so as to realize that opposite direction safety arrestment is acted on.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
It is any to be familiar with those skilled in the art in the technical scope that the utility model is disclosed in this, the change that can be readily occurred in
Or replace, all should cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with the power
The protection domain that profit is required is defined.
