The accompanying drawing explanation
Fig. 1 is the structural representation of prior art locking mechanism.
Fig. 2 be the utility model adjustable locking mechanism cut open to plan view.
Fig. 3 is the structural representation of the utility model adjustable locking mechanism.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for the utility model is described, but are not used for limiting scope of the present utility model.
As shown in Figures 2 and 3, adjustable locking of the present utility model 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 coupling shaft 9 successively, spring 5 one ends contact 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 regulating the degree that screws of lock screw, can realize regulating the position of back-up ring on coupling shaft, and spring is applied to 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, while rotating movable locking simultaneously, the extruding force difference of suffered fixed locking block, in this way, thus realize locking mechanism regulating the throttle lever coupling mechanism force.
