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.Along with the lifting that lifting and the people of production level require comfort level of riding, the shock-absorbing ability of people to bicycle proposes more and more higher requirement.In order to meet the requirement of above-mentioned shock-absorbing performance, being developed shock-absorbing front fork and being installed at the shock absorption device on vehicle body, for isolating when riding, offsetting from the vibrations between wheel and road surface.In prior art, the shock absorption device be installed on vehicle body is generally one or more spring, spring is positioned between the suspension gear (as chain stay and vertical pitch) of main body of vehicle frame and trailing wheel, and when riding, the vibrations of generation are isolated at spring place and consume, and directly improve the comfort level of riding.There is following defect in the shock-proof bicycle frame of said structure: only adopts spring as the shock-absorbing mode of shock-absorbing element, its shock-proof effect is comparatively stiff, when the hollow running into continuous road surface jolts, cause the tracking effect of surface irregularity poor owing to cannot produce enough buffering deformation, comfort level of riding cannot ensure.
Utility model content
The utility model for solve in known technology the technical matters that exists and provide a kind of structure simple, to the good buffer effect of vibrations, Shockproof bicycle frame that comfort level of riding is high.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is: a kind of Shockproof bicycle frame 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, the inner weld affixed present pipe respectively middle and upper part and bottom bracket axle on; All weld the connecting panel be connected with axis hole at the two ends of bottom bracket axle, between axis hole, erection has rotating shaft, and the outer end of vertical fork and chain stay is converged and welded and is connected with dropout, and the inner of chain stay is fixed on the outer wall of rotating shaft; Cant beam welds the first otic placode be connected with connecting bore, present pipe above welds the second otic placode be connected with axis hole, jointed shaft is provided with in the axis hole of the second otic placode, also comprise the plate that verts that two of point to be positioned at a pipe both sides are fan-shaped, pipe link is all set up between, both two corresponding exterior angles affixed with the two ends of jointed shaft respectively in both top, two pipe links are all arranged with sleeve, the sleeve at rear weld with vertical top of pitching affixed, between sleeve in front and the connecting bore of the first otic placode, spring is installed.
Advantage of the present utility model and good effect are: the utility model provides a kind of Shockproof bicycle frame of structure design advantages of simple, compared with the Shockproof bicycle frame of existing structure, by arranging by the first otic placode in the technical program, spring, second otic placode, the shockproof mechanism that the plate that verts is formed, and the top arranging vertical fork is articulated and connected with the plate that verts, the inner of chain stay and two connecting panels are articulated and connected, achieve technique effect vibration amplitude larger for rear wheel being converted into less spring deformation amount, make the suspension gear of rear wheel (vertical fork and chain stay) that the hollow fluctuating that ground followed the tracks of by wheel can be controlled better, shock-proof effect is good, efficiently avoid and jolt, comfort level of riding promotes.
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 utility model.
In figure: 1, front fork tube; 2, cant beam; 3, crossbeam; 4, cableties; 5, the first otic placode; 6, spring; 7, bottom bracket axle; 8, connecting panel; 9, rotating shaft; 10, the second otic placode; 11, vert plate; 12, chain stay; 13, vertical fork; 14, dropout.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1, the utility model comprises front fork tube 1, crossbeam 3, cant beam 2, seat pipe, bottom bracket axle 7, vertical fork 13 and chain stay 12, bottom bracket axle 7 welds the bottom of affixed present pipe, crossbeam 3 and the outer end both cant beam 2 converge and weld with front fork tube 1 affixed, inner weld affixed present pipe respectively middle and upper part and bottom bracket axle 7 on.
All weld the connecting panel 8 be connected with axis hole at the two ends of bottom bracket axle 7, between axis hole, erection has rotating shaft 9.Vertical fork 13 and the outer end both chain stay 12 are converged and are welded and be connected with dropout 14, and the inner of chain stay 12 is fixed on the outer wall of rotating shaft 9.Dropout 14 is for installing rear wheel, and the rear wheel suspension gear be made up of vertical fork 13, chain stay 12 and dropout 14 freely can rotate centered by rotating shaft 9.
Cant beam 2 welds the first otic placode 5 be connected with connecting bore, and present pipe above welds the second otic placode 10 be connected with axis hole, in the axis hole of the second otic placode 10, be provided with jointed shaft.Also comprise the plate 11 that verts that two of point to be positioned at a pipe both sides are fan-shaped, pipe link is all set up between, both two corresponding exterior angles affixed with the two ends of jointed shaft respectively in both top, and two pipe links are all arranged with sleeve.Two plates 11 that vert can do freely rotating centered by the jointed shaft on the second otic placode 10.
Wherein, the sleeve at rear weld with the top of vertical fork 13 affixed, between sleeve in front and the connecting bore of the first otic placode 5, spring 6 is installed.When rear wheel travels on the road surface risen and fallen, the suspension gear that vertical fork 13 and chain stay 12 are formed follows the tracks of the fluctuating situation on ground.When running into ground and being protruding, vertical fork 13 and chain stay 12 rotate counterclockwise centered by rotating shaft 9, and two plates 11 that vert rotate counterclockwise, and spring 6 gradually reduces; When running into that the ground caved in, vertical fork 13 and chain stay 12 rotate clockwise centered by rotating shaft 9, and two plates 11 that vert rotate clockwise, and spring 6 launches; In the process, the vibrating effect transmitted by rear wheel and ground and the front portion of vehicle frame isolated, play shock-absorbing effect.
In the present embodiment, all weld at the top of the bottom of crossbeam 3 and vertical fork 13 cableties 4 be connected with for fixing brake cable.
