Description

The skeleton angle of bicycle adjusts platform

Technical field

The utility model is related to a kind of bicycle manufacturing field, more particularly to the skeleton angle of a kind of bicycle adjusts platform.

Background technology

Bicycle is also known as bicycle or bicycle, the small-sized ground vehicles of typically two wheels, after people rides vehicle, with foot pedal It is a kind of environmentally protective vehicles for power, it is very popular.

As shown in figure 5, the skeleton 6 of bicycle is the indispensable part of bicycle, largely determines, affects The correctness and comfort of riding posture, the bottommost of skeleton 6 are the five logical 67 of cylinder, and five logical 67 horizontal direction through-holes are used Pedal is installed in the later stage, when five logical 67 axial line is horizontally disposed, five logical 67 outer wall has been set gradually from left to right down tube 63, seat pipe 64 and chain stay 66,63 one end of down tube are welded on five logical 67 outer wall, and the other end is directed toward obliquely far from five logical 67 Direction；One end of seat pipe 64 is also welded on five logical 67 outer wall, and the other end is directed toward is directed toward opposite side with down tube 63 obliquely To；66 level of chain stay is welded on five logical 67 outer wall, and chain stay 66 is two, opens form certain angle outwardly away from each other, put down 66 are pitched far from tiltedly fork 65 is welded at five logical 67 tip position, tiltedly it is separate to be fixed on seat pipe 64 for 65 ends far from chain stay 66 of fork At five logical 67 tip position；Down tube 63 is welded with head tube 61 far from five logical 67 tip position, and head tube 61 is to later stage installing handle Hand and front-wheel are welded with upper tube 62 in head tube 61, and 62 other end of upper tube is welded in seat pipe 64, and is arranged in seat pipe 64 upper Distance of the pipe 62 away from down tube 63 is more than distance of the upper tube 62 away from down tube 63 being arranged in head tube 61.

Need installation trailing wheel and rear brake, speed changer etc. a series of heavy between two chain stays 66 of the skeleton of bicycle The accessory wanted, therefore whether the angle between two chain stays 66 can be smoothed out concerning the assembly work in later stage, and bicycle Skeleton 6 in the fabrication process, due to being pipelining and its various pieces welds together one by one, to skeleton 6 During carrying out welding processing, it inevitably will appear phenomena such as colliding, overstock of skeleton 6, the angle between chain stay 66 caused to be sent out Raw to change, to influence subsequent whole assembly work, therefore the angle between two chain stays 66 is examined and adjustment is very heavy It wants.

The method of existing adjustment 66 angles of chain stay is mostly artificial progress, usually carries out chain stay 66 while assembly Angle adjusts, if occurring when assembly, when assembly is difficult can not even to assemble, operator just utilizes the tools such as hammer directly to tap Chain stay 66 so that 66 angulation change of chain stay is to adapt to assembled condition.The method of 66 angular adjustment of this chain stay is simple and crude, still Since the structure of bicycle frame 66 is complex, 66 bad fixation of skeleton when adjustment so that adjustment work is difficult to carry out.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of skeleton angle adjustment of bicycle Platform achievees the effect that the fixed stability of skeleton for improving bicycle.

The above-mentioned technical purpose of the utility model technical scheme is that：

A kind of skeleton angle adjustment platform of bicycle, including rack, it is characterised in that：Clamping group is provided in the rack Part and supporting stick, clamp assembly include the clamping platform being fixed in rack, and clamping actuator is fixedly connected on clamping platform, are clamped Drive shaft is provided on actuator, drive shaft is horizontally disposed and is rotatablely connected with clamping platform, and driveshaft end is provided with gripping block, Gripping block stretches into five logical and equal with five logical internal diameters, and supporting stick is inserted into head tube and is supported cooperation.

It is positioned in clamp assembly through the above technical solutions, the five of the skeleton of bicycle are led to, clamps actuator and drive Gripping block enters in seat pipe so that skeleton obtains preliminary clamping, and supporting stick is penetrated head tube again after clamping five is logical, prevents rack It swings, clamp assembly and supporting stick are used cooperatively, and can make rack is fixed more to stablize, at this point, whole frame Fixation is relatively stable, will not generate shaking easily, convenient for the adjustment to chain stay angle.

Preferably, the clamping platform includes the horizontally disposed bottom plate being fixed on the rack and is fixed on bottom plate two vertically The side plate of side, it includes the horizontally disposed clamping cylinder being fixedly connected on the side plate of both sides to clamp actuator, and drive shaft includes The cylinder axis being set on clamping cylinder is provided with gripping block facing each other on cylinder axis.

Through the above technical solutions, before clamping, five can be led among being put into clamp assembly, then by positioned at both sides Clamping cylinder pair five on side plate, which leads to, to be clamped, not only so that fixed effect greatly improves, but also conveniently after operation by five It is logical to remove.

Preferably, being provided with slide assemblies between the rack and supporting stick, the glide direction of slide assemblies is perpendicular to drive The axis direction of moving axis, supporting stick are fixedly connected on slide assemblies.

Through the above technical solutions, slide assemblies by the sliding in rack can adjust support roller and clamp assembly it Between distance, the skeleton for the bicycle that different sizes require is adapted to this, expands the skeleton angle adjustment platform of the bicycle Job area.
