Description
Technical field
The utility model belongs to bicycle assembly parts technical field, relates in particular to a kind of degree of depth folding bicycle frame.
Background technology
Along with the raising that development and the people of bicycle trade require bicycle convenience, traveling comfort, folding bicycle has obtained significant progress.In prior art, the type of folding bicycle is varied, and its principle is that folder is installed on vehicle frame, unclamps front and back two parts of bicycle after folder and can carry out doubling, volume-diminished after doubling, is convenient to storage and shifts.Along with the raising of people's living standard, people enjoy satisfied that travelling brings more and more.And in travelling, people still favor portability and the alerting ability that bicycle brings, therefore bicycle can carry and become inevitable demand with luggage, and folding bicycle of the prior art obviously can not meet the demand.Existing folding bicycle has still kept larger oad after folding, cannot put into the baggage container of stock size, also just cannot consign or directly put into the boot of car.Can be by Design spreading time, the less folding bicycle of oad solves the problems referred to above, but the too small bicycle of profile has been sacrificed rider's the experience that drives.Therefore, people have larger profile after wanting to allow folding bicycle launch, the hope after folding with as far as possible little profile become a kind of contradiction.
Utility model content
The utility model provides a kind of degree of depth of can carrying out to fold, reduce to greatest extent folding rear oad so that the folding bicycle frame carrying for solving the technical matters existing in known technology.
The technical scheme that the utility model is taked for the technical matters existing in solution known technology is: a kind of degree of depth folding bicycle frame comprises that front end is established sleeved saddle pipe, seat is managed and rear wheel frame, on described saddle pipe, is provided with folder; Bottom at described seat pipe is provided with the connector with axis axle sleeve, is equipped with the connecting panel hinged with it in the both sides of described connector; Described rear wheel frame comprises chain stay, vertical fork and brace, and the inner of described chain stay is fixed in described connecting panel, and the bottom of described brace is fixed in described connecting panel, top and is fixed in the top of described vertical fork; On described seat pipe, be also provided with the blocking device that described rear wheel frame top is fixed.
Advantage of the present utility model and good effect are: folding bicycle frame of the present utility model makes front-wheel fold back together with handlebar by folder is set, make trailing wheel can be rotated clockwise to the front of a pipe together with rear wheel frame and be adjacent to side by side with front-wheel by the form that rear wheel frame is designed to rotate freely centered by connector, realize the degree of depth folding, final form after folding is very compact, take volume little, can be positioned in the baggage container of stock size, be convenient to delivery or be positioned in the boot of car.
Preferably: also comprise the clothes hanger that is provided with clothes hanger roller, described clothes hanger is fixedly connected on the end of described chain stay by strut bar, is also provided with vehicle frame roller at the top of described rear wheel frame.
Preferably: described blocking device comprises the snap close that is fixed in described seat pipe and the locking bar that is fixed in described rear wheel frame top, is also provided with Jiao Dun on described locking bar.
