Description

Bicycle double-folding handlebar

Technical field

The invention belongs to the bicycle field, particularly relate to a kind of bicycle double-folding handlebar.

Background technology

The patent No. is that 95208453.8 Chinese utility model patent specification sheets discloses a kind of " bicycle folding handle ", this bicycle folding handle is a sheathed movable arm seat on vertical tube of front fork, design has a device clamping bicycle handle on movable arm seat, behind the quick detach that comes loose, bicycle handle bar winding by hand movable arm seat can rotate 180 degree up and down, and can movable arm seat be center rotation 360 deg.However, this bicycle handle is not folding yet, so still occupy bigger space after the bicycle folding, is not to be beneficial to very much the carrying out of packing and stock's management, neither be easy to carry very much and park.People urgently wish that a kind of taking up space further dwindle, be beneficial to the bicycle double-folding handlebar appearance of packing and carrying after folding.

Summary of the invention

Technical matters to be solved by this invention is: overcome the deficiency that above-mentioned bicycle folding handle exists, a kind of bicycle double-folding handlebar is provided, take up space after this bicycle double-folding handlebar folding and further dwindle, adjust rapidly when being beneficial to packing, improve packaging efficiency, be convenient to pack, collect, carry and park.

The technical solution adopted for the present invention to solve the technical problems is: bicycle double-folding handlebar comprises vertical tube, it is characterized in that: a base is installed on vertical tube, right pipe is fixed together with the cover of turning right, the pin of turning right passes the base header board and the cover of turning right, be screwed in behind the base on the plate, the right side is assemblied in pipe on the base, a left side is fixed together the pipe and the cover that turns left, the pin that turns left passes the base header board and the cover that turns left, be screwed in behind the base on the plate, a left side is assemblied in pipe on the base, right design in managing there is a bolt, right pipe or a left side pipe on design one L type groove is arranged, the bolt handle that is screwed on the bolt is positioned at L type groove, right pipe and a left side pipe on respectively design a spring anchor is arranged, the two ends of extension spring link together with these two spring anchors respectively.

The invention has the beneficial effects as follows: aforesaid bicycle double-folding handlebar, its bicycle handle is made up of a pipe and a left side to pipe right, when the part of bolt enters a left side to pipe pipe by the right side, the bolt handle is positioned at the short groove location of L type groove, and by extension spring with the right side pipe and a left side pipe tension, this state is the running condition of bicycle handle, and this sound construction is reliable, durable, and safe in utilization; When pulling bolt handle, the bolt handle is entered in the elongated slot of L type groove, promptly when bolt all is positioned at right pipe, can be with right pipe and left managing 90 degree of respectively turning back,, right close with vertical tube respectively pipe by the extension spring pulling right side managing with a left side pipe and left pipe, thus the space that bicycle handle is occupied further dwindles, adjust rapidly when being beneficial to packing, improve packaging efficiency, be convenient to packing, its volume of packing back is littler, be more convenient for carrying, also be convenient to collect and park; It is rational in infrastructure, and profile is coordinated attractive in appearance, both has been convenient to open, and also is convenient to folding, favored by the user.
