A kind of travelling aided bicycle arrangement for adjusting height

Technical field

The utility model relates to travelling aided bicycle art field, especially a kind of travelling aided bicycle arrangement for adjusting height easy to use.

Background technology

At present, the height adjustment mechanism of group driving is of a great variety, is that complex structure and difficulty of processing are big mostly, and the utility model formally provides a kind of travelling aided bicycle arrangement for adjusting height simple and reasonable for structure to supply consumer choice.

Summary of the invention

The purpose of the utility model is to solve the deficiency of above-mentioned prior art, and provides a kind of simple and reasonable for structure, and is easy to adjust, accurately, and tightens the travelling aided bicycle arrangement for adjusting height of fixation.

The utility model solves the technical scheme that its technical matters adopted: a kind of travelling aided bicycle arrangement for adjusting height, comprise that the bottom is equipped with two vehicle frames of wheel, and two vehicle frame tops are arranged with respectively can be along the up-down arm of the upper and lower adjusting of vehicle frame; The extension of up-down arm top is connected with handle, it is characterized in that said vehicle frame top is provided with toggle joint; Have on the toggle joint and be suitable for the groove that arm is pegged graft and upper and lower up-down is slided, the catch gear that communicates with groove is installed on the toggle joint, catch gear is by tighting a bolt and the elasticity projection is formed; First passage and the outside extending end that is screwed into toggle joint that tight a bolt is socketed with knob, is arranged with holddown spring on the elasticity projection and is installed in the second channel of toggle joint, and corresponding elasticity projection is provided with a plurality of location shrinkage pool with the up-down arm outer face upper edge length bearing of trend of the inboard extending end that tights a bolt; Location shrinkage pool shape corresponding with the elasticity projection and the inboard extending end that tights a bolt and adjacent two locate distance between the shrinkage pools with the elasticity projection and the spacing between tighting a bolt equate; The travelling aided bicycle arrangement for adjusting height of this structure during use, is turned on knob and is made the disengaging location shrinkage pool that tights a bolt; The up-down arm of upper and lower adjusting this moment can slide up and down along the groove of toggle joint; And when sliding, the elasticity projection in the second channel is under the effect of holddown spring, when joining the up-down arm slip that is incorporated in upper and lower adjusting with the location shrinkage pool all the time; Send " click click " sound; Point out the up-down arm of upper and lower adjusting whether to cooperate and put in place, when be adjusted to need height after, the counter-tightened knob; The extending end that tights a bolt is extended in the shrinkage pool of location; Promptly accomplish whole height adjustment process, it is simple in structure, adjusting is easy, accurate positioning.

The utility model can also adopt following technical measures to solve: as improvement further; Said up-down arm bottom outer race is connected to stop collar; Stop collar can prevent to be drawn out of after upper and lower up-down arm from getting loose in control process, reaches the spacing effect of regulating.

The inboard extending end of said elasticity projection is a small salient point, and small salient point extends in the shrinkage pool of location.

The beneficial effect of the utility model is: the travelling aided bicycle arrangement for adjusting height of the utility model, and during use, turn on knob and make bolt break away from the location shrinkage pool; The up-down arm of upper and lower adjusting this moment can slide up and down along the groove of toggle joint, and when sliding, the elasticity projection in the second channel is under the effect of holddown spring; All the time join the up-down arm that is incorporated in upper and lower adjusting when sliding with the location shrinkage pool, send " click click " sound, point out the up-down arm of upper and lower adjusting whether to cooperate and put in place; When be adjusted to need height after; Direction is tightened knob, and the bolt extending end is extended in the shrinkage pool of location, promptly accomplishes whole height adjustment process; It is simple in structure, adjusting is easy, accurate positioning.

Description of drawings

Fig. 1 is that the utility model is installed in the structural representation on the travelling aided bicycle.

Fig. 2 is the structural representation of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Extremely shown in Figure 2 like Fig. 1; A kind of travelling aided bicycle arrangement for adjusting height; Comprise that the bottom is equipped with two vehicle frames 2 of wheel 1; Two vehicle frames, 2 tops are arranged with respectively can be along the up-down arm 3 of vehicle frame 2 upper and lower adjustings, and the extension of up-down arm 3 tops is connected with handle 4, it is characterized in that; Said vehicle frame 2 tops are provided with toggle joint 5; Have on the toggle joint 5 and be suitable for the groove 6 that arm 3 is pegged graft and upper and lower up-down is slided, the catch gear 7 that communicates with groove 6 is installed on the toggle joint 5, catch gear 8 is formed with elasticity projection 9 by tighting a bolt; Tight a bolt 8 be screwed into toggle joint 5 first passage 10 and outside extending end be socketed with knob 11; Be arranged with holddown spring 12 on the elasticity projection 9 and be installed in the second channel 13 of toggle joint 5, corresponding elasticity projection 9 is provided with a plurality of location shrinkage pool 301 with the up-down arm 3 outer face upper edge length bearing of trends of the 8 inboard extending ends 901,801 that tight a bolt, and corresponding and adjacent two spacings of locating distance and the elasticity projection 9 between the shrinkage pools 301 and tighting a bolt between 8 of location shrinkage pool 301 shapes and elasticity projection 9 and the 8 inboard extending ends 901,801 that tight a bolt equate.

The travelling aided bicycle arrangement for adjusting height of this structure during use, is turned on knob 11 and is made the 8 disengaging location shrinkage pools 301 that tight a bolt; The up-down arm 3 of upper and lower adjusting this moment can slide up and down along the groove 6 of toggle joint 5, and when sliding, the elasticity projection 9 in the second channel 13 is under the effect of holddown spring 12; All the time join the up-down arm 3 that is incorporated in upper and lower adjusting when sliding with location shrinkage pool 301, send " click click " sound, point out the up-down arm 3 of upper and lower adjusting whether to cooperate and put in place with elasticity projection 9; When be adjusted to need height after; Counter-tightened knob 11 makes 8 extending ends 801 that tight a bolt extend in the shrinkage pool 301 of location and screws, and promptly accomplishes whole height adjustment process; It is simple in structure, adjusting is easy, accurate positioning.

As improvement further, said up-down arm 3 bottom outer race are connected to stop collar 14, and stop collar 14 can prevent to be drawn out of after arm 3 gets loose in control process, reach the spacing effect of regulating.

The inboard extending end 901 of said elasticity projection 9 is a small salient point; Small salient point extends in the shrinkage pool 301 of location; Small salient point sends " click click " sound with location shrinkage pool 301 touching and makes suggesting effect when the 3 upper and lower adjustings of up-down arm, but appearance is stuck can not make upper and lower adjustings of up-down arm 3 time; Its structure is ingenious, and is practical.

Above-described specific embodiment is merely the utility model preferred embodiment, the equivalent arrangements of being done according to the utility model claim such as, and the technology that all should be the utility model contains.
