Adjustable locking mechanism of the present invention, described adjustable locking mechanism also comprises set lever, and described set lever is fixedly connected in described movable locking.
Compared with prior art beneficial effect of the present invention is: also comprise lock screw, spring and back-up ring, movable locking, fixed locking block, spring and back-up ring are sleeved on coupling shaft successively, spring one end contacts with fixed locking block, the other end contacts with back-up ring, lock screw is arranged on coupling shaft, and is connected with back-up ring; Like this, by regulate lock screw screw degree, can realize regulating the position of back-up ring on coupling shaft, and different extruding forces is applied to spring, and then the extruding force of the spring regulating fixed locking block suffered on coupling shaft, like this, can realize regulating movable locking and the position of fixed locking block on coupling shaft, when rotating movable locking, the extruding force of suffered fixed locking block is different simultaneously, in this way, thus realize adjustable to throttle lever coupling mechanism force of locking mechanism.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art locking mechanism.
Fig. 2 be adjustable locking mechanism of the present invention cut open to plan view.
Fig. 3 is the structural representation of adjustable locking mechanism of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
As shown in Figures 2 and 3, adjustable locking mechanism of the present invention, comprise coupling shaft 9, movable locking 2 and fixed locking block 3, movable locking 2 contacts with fixed locking block 3, and can relatively rotate, the surface of contact of movable locking 2 matches with the surface of contact of fixed locking block 3, also comprise lock screw 8, spring 5 and back-up ring 6, movable locking 2, fixed locking block 3, spring 5 and back-up ring 6 are sleeved on coupling shaft 9 successively, spring 5 one end contacts with fixed locking block 3, the other end contacts with back-up ring 6, lock screw 8 is arranged on coupling shaft 9, and be connected with back-up ring 6, like this, by regulate lock screw screw degree, can realize regulating the position of back-up ring on coupling shaft, and different extruding forces is applied to spring, and then the extruding force of the spring regulating fixed locking block suffered on coupling shaft, like this, can realize regulating movable locking and the position of fixed locking block on coupling shaft, when rotating movable locking, the extruding force of suffered fixed locking block is different simultaneously, in this way, thus realize adjustable to throttle lever coupling mechanism force of locking mechanism.
The surface of contact of movable locking 2 and fixed locking block 3 is all set to helicoid, compared with the locking mechanism of prior art, the surface of contact of movable locking and fixed locking block is inclined-plane, and in the present invention, the surface of contact of movable locking and fixed locking block is helicoid, like this, when movable locking and fixed locking block relatively rotate, surface of contact can be made to remain be close to, frictional force is larger, also can stop in the neutral position of helicoid simultaneously, realize the self-locking of movable locking and fixed locking block relative position, in addition, the relative rotational motion of movable locking and fixed locking block is also comparatively stable, also less to the wearing and tearing of movable locking and fixed locking block.
Helicoid is at least two; Like this, can effectively prevent in movable locking and fixed locking block relative rotational motion, the inclination of movable locking and fixed locking block axis, prevents the damage to locking mechanism effectively.
Also be provided with step surface 10 between helicoid, step surface 10 is perpendicular to the axis of coupling shaft; Like this, when movable locking and fixed locking block relatively rotate to surface of contact arrival step surface, the self-locking of movable locking and fixed locking block relative position can be realized.
Helicoid is three; Like this, can effectively prevent further in movable locking and fixed locking block relative rotational motion, the inclination of movable locking and fixed locking block axis, prevents the damage to locking mechanism effectively.
In order to improve the locking effect of locking mechanism further, coupling shaft 9 is also provided with backing-up screw 7, backing-up screw 7 is arranged on coupling shaft 9, and is connected with lock screw 8; Like this, by screwing backing-up screw, the restriction to tightening screw position on coupling shaft can be realized, effectively preventing loosening of tightening screw, improving the locking effect of locking mechanism.
Coupling shaft is also provided with lining 4, and lining 4 is fixed on coupling shaft 9, and movable locking 2, fixed locking block 3 and spring 5 are all sleeved on lining 4; Like this, can effectively prevent movable locking and fixed locking block to the damage of coupling shaft.
Coupling shaft 9 is provided with keyway, back-up ring is provided with projection, projection slides in keyway; Like this, effectively can control the direction that back-up ring slides on coupling shaft, relatively rotating of anti-Sealing shield ring and coupling shaft, improve the locking effect of locking mechanism.
Adjustable locking mechanism also comprises set lever 1, and set lever 1 is fixedly connected in movable locking 2; Like this, relatively rotating of Non-follow control movable locking and fixed locking block can be realized.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
