Abstract
The invention discloses a bicycle rear fork. The bicycle rear fork comprises two mounting sleeves, a supporting tube, two rear lower fork tubes, two rear upper fork tubes, two mounting plates and two adjusting sleeves, wherein a welding notch a is formed in each rear lower fork tube, a mounting hole and a welding notch b are formed in each rear upper fork tube, each mounting plate is provided with a rear wheel mounting hole and baffles, and the baffles are located at the rearmost ends of the corresponding mounting plates; the front ends of the two rear lower fork tubes are welded to the corresponding mounting sleeves, the supporting tube is welded between the two rear lower fork tubes, the front end of each mounting plate is inserted into the welding notch a of the corresponding rear lower fork tube to be welded, the upper end of each mounting plate is inserted into the welding notch b of the corresponding rear upper fork tube to be welded, and middle holes of the two adjusting sleeves are aligned to the mounting holes of the two rear upper fork tubes respectively for welding. The bicycle rear fork has the advantages that the bicycle rear fork is of a bilateral symmetry structure, the whole bicycle rear fork is formed through welding, the cost performance is high, the rear wheel mounting holes are adjustable holes, parameter dimensions can be adjusted according to different riders, and the applicability is wide.
Description
Technical field
The present invention relates to bicycle art, particularly relate to a kind of back fork of bicycle.
Background technology
Back fork of bicycle is important composition parts of bicycle, generally comprise Seat stay and Chain stay two parts, one end of Chain stay and axis assemble, other end assembling trailing wheel, the lower end assembling trailing wheel of Seat stay, upper end is generally welded on present pipe, and back fork of bicycle belongs to a part for bicycle drive system, so very high to requirement of strength.In prior art, Seat stay and Chain stay are divided into two parts by majority, but easily like this cause the not accurate of size, assembly error, according to the service condition of current environment and client, needs the back fork of bicycle structure of a kind of general Seat stay and Chain stay one badly now.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides chain stay after a kind of bicycle that structure is simple, cost performance is high.
The technical solution adopted for the present invention to solve the technical problems is: a kind of back fork of bicycle of the present invention is bilateral symmetry, comprise two installation sleeves, a support tube, two rear lower fork tubes, two Seat stay pipes, two adapter plates and two adjusting sleeves, wherein rear lower fork tube is provided with welding otch a, Seat stay pipe is provided with mounting hole and welding otch b, adapter plate is provided with trailing wheel mounting hole and baffle plate, baffle plate is positioned at the rearmost end of adapter plate, be used for assembling bicycle chain regulator, the front end of two rear lower fork tubes is welded on installation sleeve respectively, support tube is welded between two rear lower fork tubes, the interior welding of welding otch a of rear lower fork tube is inserted in the front end of adapter plate, the interior welding of welding otch b of Seat stay pipe is inserted in the upper end of adapter plate, the mesopore of two adjusting sleeves welds respectively with after the mounting hole centering of two Seat stay pipes, more than complete the welded structure of this back fork of bicycle,
Preferably, wherein weld otch a identical with the gauge of adapter plate with the width dimensions of welding otch b, coordinated by tolerance dimension, ensure even weld;
Preferably, wherein adapter plate is integral type structure;
Preferably, wherein trailing wheel mounting hole is slotted hole structure, can adjust the parameter size of bicycle according to different bicyclists.
Beneficial effect of the present invention is: this back fork of bicycle is bilateral symmetry, overall employing welding fabrication, cost performance is high, two ends use plank frame assembling trailing wheel, more firm, trailing wheel mounting hole is adjustable orifice, can adjust the parameter size of bicycle according to different bicyclists, applicability is wide, is convenient to promote.
