Pulling wire handle mechanism.
Background technique
Air spring seat has height adjusting function, and by the way that different gears is arranged, rotating handle passes through gear tune
Section, is adjusted bracing wire, may be implemented any adjusting to height of seat, handle of every rotation, and height of seat is corresponding
Generation once change, multiple rotary handle, the position of handle is different, can make troubles to the personnel used.
However, multiple rotary handle when the pulling wire handle mechanism of air spring seat in the prior art uses, handle
Position is different, it is therefore desirable to which one kind can make handle self-return, the pulling wire handle mechanism without influencing bracing wire length.
Summary of the invention
The adjustable pulling wire handle mechanism with self-return function that the purpose of the present invention is to provide a kind of, to solve existing feelings
Under condition, air spring seat has height adjusting function, and by the way that different gears is arranged, rotating handle is adjusted by gear, right
Bracing wire is adjusted, and any adjusting to height of seat, handle of every rotation, the corresponding generation of height of seat may be implemented
The problem of primary to change, the position of multiple rotary handle, handle is different, can make troubles to the personnel used, and the present invention mentions
The adjustable pulling wire handle mechanism with self-return function supplied can be such that handle realizes automatic in the case where bracing wire length is constant
Return.
The present invention provides a kind of adjustable pulling wire handle mechanism with self-return function, including bracing wire, shell and with institute
State shell pass through the first rotation axis be rotatablely connected cap, the bracing wire sequentially pass through the top of shell and cap and with it is described
Clamping, is equipped with the first elastic component inside cap between the cap and shell；

The working principle of the invention and workflow: the adjustable pulling wire handle provided by the invention with self-return function
Mechanism, to solve in existing situation, air spring seat has height adjusting function, by the way that different gears is arranged, rotates hand
Handle is adjusted by gear, and bracing wire 30 is adjusted, and may be implemented any adjusting to height of seat, handle of every rotation,
The corresponding generation of height of seat is primary to be changed, and the position of multiple rotary handle, handle is different, can be brought not to the personnel used
Just the problem of.When adjusting height of seat, knob 15 is rotated clockwise, drives turntable 12 and the first pawl 122 and the second pawl
123 common rotations, under the action of the first limited block 13,122 bottom end of the first pawl is moved to the position close to 12 center of circle of turntable
The dentalation being detached from ratchet 21, the second pawl 123 drive ratchet 21 and cap 20 to rotate, and cap 20 rotates clockwise,
Bracing wire 30 is lowered to drive gear change, and height of seat changes, and when knob 15 rotates, drives the torsion bullet of winding on it
Spring twists, due to having put aside elastic potential energy in torque spring, when no external force is on knob 15, torque spring due to
Restore elastic deformation, makes the revolution of knob 15,15 rotating belt turn disk 12 of knob and the first pawl 122 and the second pawl 123
It rotates counterclockwise, at this point, the first pawl 122 is engaged with the dentalation on ratchet 21, however, since the first spring rack gear 51 is
Fixed setting, second spring rack gear 52 are engaged with the first spring rack gear 51 and 20 outer surface of cap, and cap 20 is in the first bullet
Under property 50 overall function of part, remain stationary, the first pawl 122 is engaged with ratchet 21 respectively with the second pawl 123,30 length of bracing wire
It is motionless.It follows that the adjustable pulling wire handle mechanism provided by the invention with self-return function can 30 length of bracing wire not
In the case where change, handle is made to realize self-return.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
