The specific embodiment

Below in conjunction with the accompanying drawing in utility model embodiment, the technical scheme in utility model embodiment is clearly and completely described, obviously, described embodiment is only utility model part embodiment, rather than whole embodiment.Embodiment based in utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of utility model protection.

Front and rear direction described in utility model corresponds respectively to the left and right direction in Fig. 1, the upper and lower described in utility model to correspond respectively to upper and lower in accompanying drawing 1 to.

Utility model embodiment 1 provides a kind of underbody car height adjusting mechanism.Referring to Fig. 1-7, this mechanism comprises: base 1, adjusting leg 2 and knob part 3.Wherein on base 1, on the sidewall of relative adjustment leg 2, offer along the vertical direction guide groove 12.Regulate on leg 2 and be formed with towards the outstanding projection 22 extending of base 1.When base 1 coincides with adjusting leg 2, regulate the projection 22 on leg 2 to be plugged in corresponding guide groove 12, realized base 1 along regulating sliding up and down of leg 2.

Regulate leg 2 can have various shape.In the utility model, can adopt the rectangular shape shown in Fig. 1.

Regulate on sidewall relative with knob part 3 on leg 2 and at least two draw-in grooves 21 of arranging along above-below direction.The quantity of its draw-in groove 21 is determined by demand.On base 1, specifically can be its rear and offer through hole 11.Knob part 3 is rotatable to be plugged in through hole 11.The lower end of knob part 3 is provided with limiting stopper 31.This knob part 3 specifically can be a S. A..

Knob part 3 and draw-in groove 21 form the lockout mechanism regulating between leg 2 and base 1.The relative through hole 11 of knob part 3 can rotate to two control positioies, comprises primary importance and the second place.When knob part 3 is rotated to primary importance, limiting stopper 31 is plugged in one of them draw-in groove 21, latch-up structure is in the lock state, when knob part 3 is rotated to the second place, when soon knob part rotates to certain angle scope, this limiting stopper 31 departs from draw-in groove 21, and latch-up structure is in released state.For convenience of manual rotation knob part 3, the rotating part 32 above a protrusion through hole 11 can be set in the upper end of knob part 3, specifically can be arranged to the circular rotating button shown in Fig. 1.

In a specific embodiment of the present utility model, limiting stopper (31) is all hangnail shape as shown in Figure 4 with draw-in groove (21).

Consider and knob part will be plugged in through hole 11, in the utility model, in rotating part 32 and limiting stopper 31, to have at least one to be separable structures with the body of knob part 3.

As when rotating part 32 is separable structure for the body with knob part 3, knob part 3 can be passed to through hole 11 along direction from top to bottom, then rotating part 32 is connected to the upper end of knob part 3.

When latch-up structure release, can manually to the height of base 1, regulate.As while wanting to heighten base 1, can be when release, manually by the raising of base 1, then locking.

When latch-up structure release, base 1 can be because own wt, toward falling, therefore, in a preferred embodiment, in the time will turning down the position of base 1, can only rotate 3 releases of knob part.

In the utility model, can between knob part 3 and base 1, be provided with return unit, for applying reset force to knob part 3.Make to automatically reset after its release, insert in next draw-in groove 21.

The height adjusting mechanism of a kind of underbody car above this utility model being provided, be described in detail, applied specific case herein the principle of utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method and the core concept thereof of utility model; Meanwhile, for one of ordinary skill in the art, the thought according to utility model, all will change in specific embodiments and applications.In sum, this description should not be construed as the restriction to utility model.
