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 the coupling shaft successively, spring one end contacts with fixed locking block, the other end contacts with back-up ring, lock screw is installed on the coupling shaft, and links to each other with back-up ring; Like this, by regulating the degree that screws of lock screw, can realize regulating the position of back-up ring on coupling shaft, and spring is applied different extruding forces, and then regulate the extruding force of fixed locking block suffered spring on coupling shaft, like this, can realize regulating movable locking and the position of fixed locking block on coupling shaft, when rotating movable locking simultaneously, the extruding force of suffered fixed locking block is different, in this way, thus realize locking mechanism regulating the throttle lever coupling mechanism force.
Description of drawings
Fig. 1 is the structural representation of prior art locking mechanism.
Fig. 2 be adjustable locking of the present invention mechanism cut open to plan view.
Fig. 3 is the structural representation of adjustable locking of the present invention mechanism.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
As shown in Figures 2 and 3, adjustable locking of the present invention mechanism, 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 the coupling shaft 9 successively, spring 5 one ends contact with fixed locking block 3, the other end contacts with back-up ring 6, and lock screw 8 is installed on the coupling shaft 9, and links to each other with back-up ring 6; Like this, by regulating the degree that screws of lock screw, can realize regulating the position of back-up ring on coupling shaft, and spring is applied different extruding forces, and then regulate the extruding force of fixed locking block suffered spring on coupling shaft, like this, can realize regulating movable locking and the position of fixed locking block on coupling shaft, when rotating movable locking simultaneously, the extruding force of suffered fixed locking block is different, in this way, thus realize locking mechanism regulating the throttle lever coupling mechanism force.
The surface of contact of movable locking 2 and fixed locking block 3 all is set to helicoid; Compare with the locking mechanism of prior art, the surface of contact of movable locking and fixed locking block is the inclined-plane, and among 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 is remained to 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 process that relatively rotates of movable locking and fixed locking block is also comparatively stable, and is also less to the wearing and tearing of movable locking and fixed locking block.
Helicoid is at least two; Like this, can prevent effectively that movable locking and fixed locking block from relatively rotating in the process, the inclination that movable locking and fixed locking block are axial prevents the damage to locking mechanism effectively.
