The invention belongs to the technical field of bicycle parts and particularly relates to a bicycle frame with a fender. The bicycle frame comprises a front fork tube (1), a crossbeam (2), a diagonal beam (4), a seat tube (5), an intermediate shaft bushing (6), seat stays (8) and chain stays (9). The intermediate shaft bushing (6) is fixedly welded at the bottom end of the seat tube (5), the outer ends of the crossbeam (2) and the diagonal beam (4) are converged and fixedly welded with the front fork tube (1), and the inner ends of the crossbeam (2) and the diagonal beam (4) are fixedly welded with the middle upper portion of the seat tube (5) and the intermediate shaft bushing (6). The inner ends of the seat stays (8) and the chain stays (9) are fixedly welded on the middle upper portion of the seat tube (5) and the intermediate shaft busing (6), and the outer ends of the seat stays (8) and the chain stays (9) are converged and fixedly welded with rear fork piece (10). The bicycle frame further comprises a rear fender (7) comprising a support rod portion and an arc-shaped plate portion, the inner end of the support rod portion is fixedly welded with the middle upper portion of the seat tube (5), and when a wheel is mounted on the rear fork pieces (10), the arc-shaped plate portion is arranged above the wheel.
Description
Technical field
The invention belongs to bicycle assembly parts technical field, particularly relate to a kind of cycle frame with mud guard.
Background technology
Cycle frame is the main body frame of bicycle, structure generally comprises crossbeam, cant beam, seat pipe, vertical fork and chain stay, its center member and cant beam front end converge at front fork tube, front fork tube is for installing bicycle front fork, cant beam, seat pipe and chain stay converge at bottom bracket axle, bottom bracket axle is for installing bicycle middle shaft, and vertical crotch is located between seat pipe and chain stay.Bicycle needs after completing assembling usually for front and back wheel installs front & rear mudguard respectively, for the body preventing mud point to be splashed to bicyclist when riding in muddy water road surface.In prior art, general and the vehicle frame of front & rear mudguard is Split type structure, the later stage installs, material is generally plastics, there is following defect in the mud guard of said structure: structural strength is lower, easily occur when riding damaged under shock effect and extraneous effect of colliding with, and then the function of gear mud cannot be played.
Summary of the invention
The present invention for solve in known technology the technical matters that exists and provide a kind of structure simple, with the cycle frame of high structural strength rear mudguard.
The technical scheme that the present invention takes for the technical matters existed in solution known technology is: a kind of cycle frame with mud guard comprises front fork tube, crossbeam, cant beam, seat pipe, bottom bracket axle, vertical fork and chain stay, the bottom of the affixed present pipe of bottom bracket axle welding, the outer end of crossbeam and cant beam converge and weld with front fork tube affixed, inner weld affixed present pipe respectively middle and upper part and bottom bracket axle on, vertical pitch and on middle and upper part that the inner of chain stay welds affixed present pipe respectively and bottom bracket axle, outer end converges and welds and be connected with dropout; Also comprise the rear mudguard of metal material, it comprises strut bar part and arc part, and the middle and upper part of the affixed present pipe of the inner welding of strut bar part, when wheel is installed in dropout, arc part is positioned at the top of wheel.
Advantage of the present invention and good effect are: the cycle frame that the invention provides a kind of structure design advantages of simple, compared with the cycle frame of existing structure, the technical program is by welding the rear mudguard of affixed metal material in the middle and upper part of vehicle-frame seat-tube, and rear mudguard is set is made up of strut bar part and arc part, solve low, the fragile problem of structural strength that rear mudguard that existing parts processing installs fixing plastic material again brings.
Preferably: described rear mudguard is one-body molded obtained through die press technology for forming by same metal pipe material.
Preferably: the position of weld of strut bar part and seat pipe is stood at two and pitched between the position of weld of seat pipe.
Preferably: all weld at the top of the bottom of crossbeam and vertical fork the cableties be connected with for fixing brake cable.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present invention.
In figure: 1, front fork tube; 2, crossbeam; 3, cableties; 4, cant beam; 5, seat pipe; 6, bottom bracket axle; 7, rear mudguard; 8, vertical fork; 9, chain stay; 10, dropout.
Detailed description of the invention
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1, the present invention includes front fork tube 1, crossbeam 2, cant beam 4, seat pipe 5, bottom bracket axle 6, vertical fork 8 and chain stay 9, bottom bracket axle 6 welds the bottom of affixed present pipe 5 for installing the axis of bicycle.Crossbeam 2 and the outer end both cant beam 4 converge and weld with front fork tube 1 affixed, inner weld affixed present pipe 5 respectively middle and upper part and bottom bracket axle 6 on, the front fork of bicycle is arranged on front fork tube 1.On the middle and upper part that vertical fork 8 and the inner both chain stay 9 weld affixed present pipe 5 respectively and bottom bracket axle 6, outer end converges and welds and be connected with dropout 10, vertical fork 8, chain stay 9 and dropout 10 is symmetrical two groups, and the wheel shaft erection of rear wheel is arranged in two dropout 10 in left and right.
Also comprise the rear mudguard 7 of metal material, it comprises strut bar part and arc part, the middle and upper part of the affixed present pipe 5 of the inner welding of strut bar part, when wheel is installed in dropout 10, arc part is positioned at the top of wheel, and arc part stops the mud point that wheel throws away.
In the present embodiment, rear mudguard 7 is one-body molded obtained through die press technology for forming by same metal pipe material, adopts the advantage of above-mentioned processing technology to be: concise in technology, work efficiency is high, rear mudguard 7 structural strength obtained is high, and without the need to welding, smooth surface is smooth.The position of weld of strut bar part and seat pipe 5 is between two vertical forks 8 and the position of weld of seat pipe 5, and the solder joint of such rear mudguard 7 and seat pipe 5 is hidden between vertical fork 8 and the solder joint of seat pipe 5, and appearance is better.
In the present embodiment, all weld at the top of the bottom of crossbeam 2 and vertical fork 8 cableties 3 be connected with for fixing brake cable.
