Abstract

The utility model is a location adjustable auxiliary wheel, comprising a fixed piece, a wheel shaft pivoted with the fixed piece, a wheel body connected with the wheel shaft, and a positioning piece arranged on the wheel shaft. The fixed piece has a plurality of serially arranged position limit parts, and a height difference is formed along a vertical direction between adjacent position limit parts; the positioning piece is provided with a wedge block part that can automatically revert to in-situ and be wedged with any of the position limit parts; when the wedge block part breaks away from the position limit part, the wheel shaft can drive the wheel body to change the distance from the ground until the wedge block part is wedged with the position limit part that is in a corresponding height, so as to enable a re-positioning of the wheel shaft.

Description

The auxiliary wheel of adjustable position

Technical field

The utility model patent relates to a kind of auxiliary wheel, is meant a kind of auxiliary wheel of operating easy adjustable position especially.

Background technology

Children are when practising by bike, often because the sense of equilibrium is not good, and the time have body inclination to cause the situation of falling, make children's torso injured and produce psychological fear therefore, topple in order to prevent bicycle, Regular Bicycle can install two auxiliary wheels additional in addition in trailing wheel two sides, make bicycle reposefully vertically-arranged on a ground.

Shown in the 12nd figure, its auxiliary wheel 1 has a wheel shaft 11 1 wheel bodys 12 and a locking part 13 wheel shafts 11 to have a vertical surface 111 and a horizontal segment 112 respectively, and several perforation 113 wheel bodys 12 that run through vertical section 111 along an axis X direction are hubbed on these wheel shaft 11 horizontal surfaces 112 1 end locking parts 13 and have a screw rod 131, and the nut 132 that screws togather of screw rod 131 therewith, screw rod 131 is fixed on the fork arm 22 of bicycle one trailing wheel 21 2 sides.Wheel shaft 11 need only be abutted on the fork arm 22, screw rod 131 is passed by wheel shaft 11 arbitrary perforation 113, and screw togather with nut 132, though just wheel shaft 11 and wheel body 12 lockings can be able to be reached the purpose that auxiliary wheel 1 is installed at the above-mentioned member in fork weldering 22 both sides, when reality is used, still exist following shortcoming to need to be resolved hurrily:

For cooperating rider's study schedule, wheel shaft 11 can be by the difference of perforation 113 height, change locking position, and then adjustment wheel body 12 and ground-surface distance, but, when adjusting locking position each time, all must utilize instrument pine oil nut 132 just can unload wheel shaft 11, and after unloading wheel shaft 11, also need repeat the previous action that wheel 11 and locking nut 132 are installed again, could adjust wheel body 12 and the whole process of ground-surface distance, not only time-consuming consumption power, and ride under the situation of a bicycle together many people, each cyclist must repeat aforementioned loaded down with trivial details adjustment action, just can meet the user demand of oneself, obviously, this auxiliary wheel 1 does not meet the demand in rider's use using cooresponding inconvenience in the operation.

Summary of the invention

Therefore, the purpose of this utility model is that a kind of auxiliary wheel that can adjust the adjustable position of terrain clearance simply is being provided.

So the auxiliary wheel of an adjustable position of the above-mentioned utility model of foundation comprises: a connecting element one wheel shaft one is taken turns axis body and positioning piece.This connecting element has the limiting section that number is arranged in regular turn, and every adjacent limiting section is formed with the potential difference of height along a vertical direction.This wheel shaft has a vertical section and a horizontal segment, this vertical section is with an end and this connecting element pivot knot, making horizontal segment can be to link with an end of taking turns axle horizontal around this wheel body of axis turn, can change the vertical section that this locations of the ground-surface height and position of distance is arranged on wheel shaft with the horizontal segment turn, and have one can automatically involution original position and with arbitrary limiting section fastener, make wheel shaft obtain spacing and can't activity by this, when the fastener of locations breaks away from the limiting section of connecting element, this wheel shaft just can driven wheel structural reform displacement height and position overhead, engage with the limiting section of relative height to fastener, make wheel shaft regain the location.

The specific embodiment

As shown in figure 34, the preferred embodiment of the utility model auxiliary wheel is to be separately positioned on two fork arms 32 of a bicycle (figure a does not show) trailing wheel 31 2 sides.This auxiliary wheel comprises: a connecting element 4-wheel shaft 5 one wheel bodys 6 and positioning piece 7.

This connecting element 4 have number along the limiting section of camber trajectory alignment respectively should be spacing be the jack 41 that runs through connecting element 4 along an axis X direction, and 41 of every adjacent jacks are formed with potential differences highly along a vertical direction.

This wheel shaft 5 have a vertical section 51 and a horizontal segment 52 these vertical sections 51 be with an end 511 at a pivot position A and this connecting element 4 pivots knot, make the horizontal segment 52 can be around this axis X turn.

This wheel body 6 is to tie with an end 521 pivots of wheel shaft 5 horizontal segments 52.

This locations 7 has an axle bed 71-who is positioned at wheel shaft 5 vertical sections 51 and is contained in axle bed 71 interior elastic element 72-pass axle bed 71 and elastic element 72 along this axis X fastener, and a bolt head 74 these fasteners are latches 73 at present embodiment, and have an end 731 that passes axle bed 71 and can engage with jack 41, and one passes the axle bed 71 and the other end 732 (referring to 5th figure) affixed with bolt head 74.

As the 5th, 6 figure, during adjustment, need only be to pull the bolt head 74 of moving locations 7, make jack 41 that an end 731 of this latch 73 breaks away from connecting elements 4 by this, the vertical section 51 of this wheel shaft 5 can be that swivel point drives horizontal segment 52 along the turn of camber track with axle pivot position A just, the axle pivot angle of vertical section 51 connecting elements 4 is changed, and then change wheel body 6 distance overhead.

After wheel body 6 is adjusted to suitable height and position, just can be as long as unclasp the bolt head 74 of locations 7 by the elastic-restoring force of elastic element 72, ejection latch 73 homings, and engage with the jack card 41 of an end 731 with connecting element 4 relative positions, make wheel shaft 5 obtain the location.

According to the above as can be known, the adjustable position of the utility model auxiliary has a row advantage and an effect:

The utility model need only just can be adjusted angle and the wheel body 6 and ground-surface spacing of wheel shaft 5 arbitrarily by the action that spurs or unclasp latch 73, and can cooperate rider's study schedule or different riders' demand.So the utility model without any need for instrument, uses operational comfort feature and practicality and can promote significantly on adjusting.
