Abstract
The utility model patent provides a kind of folding bicycle auxiliary wheel, and its structure comprises: the tube bank of cardan wheel (1), auxiliary wheel pipe (2), auxiliary wheel (3), inverted T shape support (4).When cycling, inverted T shape support inserts auxiliary wheel pipe, and cardan wheel one in front and one in back, does not hinder foot-operated rotation, then locks auxiliary wheel tube bank.When bicycle folds, inverted T shape support pulls out one section from auxiliary wheel pipe, then rotates 90 degree, makes cardan wheel one the first from left right, then locks auxiliary wheel tube bank.The utility model inverted T shape support has certain length, is that two cardan wheels distance is enough large, thus is not easy to turn on one's side in implementation or draw during row.Inverted T shape support can go deep into auxiliary wheel pipe when riding, and pulls out when folding, thus neither impact is ridden, and also can keep back seat level when folding, conveniently on back seat, places the article such as knapsack.Two cardan wheels are installed, when carrying out or drawing row easy controlling party to.
Description
Technical field
The utility model patent relates to a kind of folding bicycle supplementary structure, and specifically a kind of folding bicycle is conveniently carried out at folded state or drawn capable auxiliary wheel.
Background technology
Folding bicycle, for the convenience of the users by bus on bicycle band or design at subway, in order to carry out more easily or tow bicycle, should be worked as and install auxiliary wheel to folding bicycle, but existing auxiliary wheel exists following three place's shortcomings.One, the distance between two auxiliary wheels too near (even a wheel), causes the stabilizing bicycle after folding qualitative bad, thus carrying out or easily turning on one's side when towing, injures other pedestrians.Two, the length of auxiliary wheel support is unadjustable.Support is too short, and the rear bicycle after folding can not level, causes placing the article such as knapsack; Support is oversize, and bicycle is being ridden through convex roadblock, and auxiliary wheel easily encounters roadblock.Three, auxiliary wheel can not turn to, and causes the direction when carrying out or towing of the bicycle after folding wayward.
Summary of the invention
The utility model patent provides a kind of folding bicycle auxiliary wheel, and its structure comprises: the tube bank of cardan wheel (1), auxiliary wheel pipe (2), auxiliary wheel (3), inverted T shape support (4).Auxiliary wheel pipe one end is welded on the below of pedal spindle, becomes 30-60 degree angle with seat pipe.Auxiliary wheel pipe other end jag, and auxiliary wheel tube bank is installed.Inverted T shape support one end is inserted in auxiliary wheel pipe, and the other end installs two cardan wheels.When cycling, inverted T shape support inserts auxiliary wheel pipe, and cardan wheel one in front and one in back, does not hinder foot-operated rotation, then locks auxiliary wheel tube bank.When bicycle folds, inverted T shape support pulls out one section from auxiliary wheel pipe, then rotates 90 degree, makes cardan wheel one the first from left right, then locks auxiliary wheel tube bank.
The beneficial effects of the utility model are: inverted T shape support has certain length, are that two cardan wheels distance is enough large, thus are not easy to turn on one's side in implementation or draw during row.Inverted T shape support can go deep into auxiliary wheel pipe when riding, and pulls out when folding, thus neither impact is ridden, and also can keep back seat level when folding, conveniently on back seat, places the article such as knapsack.Two cardan wheels are installed, when carrying out or drawing row easy controlling party to.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of folding bicycle auxiliary wheel of the utility model when cycling.
Fig. 2 is the schematic diagram of a kind of folding bicycle auxiliary wheel of the utility model.
Detailed description of the invention
The utility model patent provides a kind of folding bicycle auxiliary wheel, and as depicted in figs. 1 and 2, its structure comprises: the tube bank of cardan wheel (1), auxiliary wheel pipe (2), auxiliary wheel (3), inverted T shape support (4).Auxiliary wheel length of tube is arranged on 5-40cm according to wheel diameter, and its one end is welded on the below of pedal spindle, becomes 30-60 degree angle with seat pipe.Auxiliary wheel pipe other end jag, and auxiliary wheel tube bank is installed.One end of inverted T shape support is inserted in auxiliary wheel pipe, and its length is consistent with auxiliary wheel pipe, and the other end installs two cardan wheels.When cycling, inverted T shape support inserts auxiliary wheel pipe, and cardan wheel one in front and one in back, does not hinder foot-operated rotation, then locks auxiliary wheel tube bank.When bicycle folds, inverted T shape support pulls out one section from auxiliary wheel pipe, then rotates 90 degree, makes cardan wheel one the first from left right, then locks auxiliary wheel tube bank.
Claims (1)
