Abstract
The utility model discloses a bicycle which comprises a front wheel, a rear wheel, a front fork, a handle, a chain wheel, a pedal, a saddle, a cross beam for connecting the front fork and the saddle, a front oblique beam for connecting the front fork and the chain wheel, a rear oblique beam for connecting the rear wheel and the front oblique beam, a short beam connected between the cross beam and the front oblique beam, and a shock absorbing spring connected between the short beam and the rear oblique beam, wherein a mounting groove is formed in the front oblique beam along the length direction, a mounting hole is formed in the rear oblique beam and is close to the front oblique beam, and the front oblique beam is fixedly connected with the rear oblique beam through a bolt. The bicycle has the advantages that the rear oblique beam can slide on the front oblique beam, so that the distance between the front and rear wheels can be easily adjusted, tightness of a chain is adjusted, and the method is simple and easy to implement and is not limited by time, site and technology; and the shock absorbing spring connected with the rear oblique beam can reduce shock of the bicycle, and the height of the saddle can be adjusted, so that the bicycle is comfortable to ride.
Description
Technical field
The utility model relates to a kind of bicycle, is specifically related to the adjustable bicycle of distance between a kind of front and rear wheel.
Background technology
Bicycle has been dissolved in people's the life as the vehicle, change along with people life style, the various bicycles with certain special purpose that obtain that improve take bicycle as the basis enter in our life gradually, for example be used for body-building mountain bike, be used for derailleur of raising speed etc.In use, such a case often can occur in bicycle that especially can speed change: chain-loose, even split away off from gear.And people's countermeasure is exactly: the chain that more renews, perhaps fastening correlated parts.The former need to arrive a repairing that repairs, and is subjected to the restriction in place, and the latter can only deal with problems in short-term, uses after a period of time, and identical problem also can occur.In addition, all bicycles in use, when especially travelling on uneven road surface, significantly jolting, can make rides feels under the weather.Thus, chain-loose and obviously jolt and use bicycle to bring certain puzzlement to people, and very perfect solution is not also arranged at present.
The utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide the distance between a kind of good damping effect, the front and rear wheel adjustable bicycle, the adjusting of the very convenient chain degree of tightness of this bicycle, and easy to operate, be not subjected to the restriction of time, place, technology.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of bicycle, comprise: front-wheel, trailing wheel, be arranged at front fork on the front-wheel, with fixing handgrip, the sprocket wheel that is connected with trailing wheel of front fork, be fixed on the pedal on the sprocket wheel, and vehicle seat, it is characterized in that, also comprise: the crossbeam that connects front fork and vehicle seat, the front cant beam that connects front fork and sprocket wheel, the rear cant beam of connection trailing wheel and front cant beam; Aforementioned front cant beam is formed with mounting groove along its length, and rear cant beam nearby cant beam end is formed with mounting hole, and front cant beam and rear cant beam are bolted to connection.
Aforesaid bicycle is characterized in that, also comprises: be connected in the short beam between crossbeam and the front cant beam, be connected in the damping spring between aforementioned short beam and the rear cant beam.
Aforesaid bicycle is characterized in that, the end that aforementioned crossbeam is connected with vehicle seat is formed with installation sleeve, and aforementioned vehicle seat is formed with the mounting rod that cooperates with aforementioned installation sleeve; Aforementioned mounting rod inserts the interior fixedly vehicle seat of installation sleeve.
Usefulness of the present utility model is: rear cant beam can slide at front cant beam, thus the distance between can the easy adjustment front and rear wheel, and then elasticity that can adjusting chain, method is simple, easily realize, is not subjected to the restriction of time, place, technology; Vehicle seat only is connected with crossbeam, and is provided with damping spring at rear cant beam, and formation double damping system can obviously reduce the vibrations of bicycle, make ride more comfortable.
Description of drawings
Fig. 1 is the structural representation of a specific embodiment of bicycle of the present utility model;
The implication of Reference numeral among the figure: 1-front-wheel, 2-trailing wheel, 3-front fork, 4-handgrip, 5-sprocket wheel, 6-pedal, the 7-vehicle seat, cant beam before the 8-crossbeam, 9-, cant beam behind the 10-, 11-mounting groove, 12-mounting hole, the 13-bolt, 14-short beam, 15-damping spring, 16-installation sleeve, 17-mounting rod.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done concrete introduction.
With reference to Fig. 1, bicycle of the present utility model comprises: front-wheel 1, trailing wheel 2, be arranged at front fork 3 on the front-wheel 1, with fixing handgrip 4, the sprocket wheel 5 that is connected with trailing wheel 2 of front fork 3, be fixed on the pedal 6 on the sprocket wheel 5, and vehicle seat 7, also comprise: crossbeam 8, front cant beam 9 and rear cant beam 10.Crossbeam 8 is used for connecting front fork 3 and vehicle seat 7, and front cant beam 9 is used for connecting front fork 3 and sprocket wheel 5, and rear cant beam 10 is used for connecting trailing wheel 2 and front cant beam 9.In order to make distance between front-wheel 1 and the trailing wheel 2 adjustable and then reach the purpose of the elasticity of adjusting chain, the rear cant beam 10 that connects trailing wheel 2 can be regulated with respect to the position of front cant beam 9, concrete, front cant beam 9 is formed with mounting groove 11 along its length, one end end of the close front cant beam 9 of rear cant beam 10 is formed with mounting hole 12, after adjusting the relative position of front cant beam 9 and rear cant beam 10, again by bolt 13 captive joints the two.The method of above-mentioned adjusting chain elasticity is simple, easily realization, is not subjected to the restriction of time, place, technology.
As a kind of preferred scheme, bicycle of the present utility model also comprises: damping spring 15, and be used for to support, the fixing short beam 14 of damping spring 15.Short beam 14 is connected between crossbeam 8 and the front cant beam 9, and damping spring 15 is connected between short beam 14 and the rear cant beam 10, and bicycle is had good damping effect, improves the comfort level of riding.
In order to adapt to different bicyclists' the requirement of riding, the height of its vehicle seat 7 of bicycle of the present utility model can be regulated.Concrete, the end that crossbeam 8 is connected with vehicle seat 7 is formed with installation sleeve 16, and corresponding, vehicle seat 7 is formed with the mounting rod 17 that cooperates with installation sleeve 16, and mounting rod 17 insertion installation sleeves 16 are interior and adjust behind the height fixedly that vehicle seat 7 gets final product.Because 7 of vehicle seats are connected with crossbeam 8, so vehicle seat 7 also has certain damping effect, if crossbeam 8 has certain toughness, then damping effect is more obvious.Damping seat of vehicle 7 consists of a double damping system with damping spring 15, has improved the comfort level of riding.
Need to prove, above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in the protection domain of the present utility model.
