Description

Folding frame for bicycle

Technical field

The utility model relates to a kind of folding frame for bicycle, relates in particular to a kind of can shock-absorbing can folding again, and can be adapted to the rider's of different heights folding frame for bicycle.

Background technology

Bicycle is as a kind of vehicle and fitness tool, is extensive use of by people and likes.Bicycle product in the market, the general all the time change that all only limits to outward appearance, and real performance does not have too big change.Though, shock-absorbing car, four connecting rod cars and various folded bicycle have appearred, and their function all is a mono-, perhaps has only shock-proof effect or has only folder function or can only be suitable for the sustained height rider.

Summary of the invention

The purpose of this utility model is to provide a kind of and can shock-absorbing can folds again, and the folding frame for bicycle that can make things convenient for masculinity and femininity to ride.

For achieving the above object, the utility model provides a kind of folding frame for bicycle, comprises pipe, a Seat stay, a telescopic pipe and two groups of Shock absorbers on pipe, the Chain stay; Should go up rotatable being articulated on this time pipe of pipe, this Chain stay is captiveed joint with this time pipe; Should go up its inside of pipe is hollow, and it is provided with a Fixture for tube of seat; The upper end of this telescopic pipe is inserted on this in pipe, adjusts this Fixture for tube of seat this telescopic pipe is connected in different stationkeeping with last pipe; This first group of Shock absorber comprises two Shock absorbers of installing side by side, their two ends are rotatable respectively be articulated on this telescopic pipe and this Seat stay on; This second group of Shock absorber comprises at least one Shock absorber, and its two ends are rotatable respectively to be articulated on this Chain stay and this Seat stay.

The utlity model has following beneficial effect: the utility model has been realized good shock-proof effect by cooperatively interacting of two groups of Shock absorbers, in the time of by bike as snug as a bug in a rug; When using, this bicycle can adjust according to cyclist's sex, the male sex generally is that leg gets on and off across crossing seat behind car, this telescopic pipe and last pipe can be in the higher positions, during adjustment telescopic pipe being extracted out the pipe and adjust this Fixture for tube of seat on this makes this telescopic pipe captive joint with last pipe, this moment, this first Shock absorber and second Shock absorber were upright state, thereby with this telescopic pipe and the lifting upward of last pipe; Be inclined cross from the place ahead and get on and off and the women generally is a leg, this telescopic pipe and last pipe must be at lower positions, form convenient for female getting on the bus of neutral gear ability, when adjusting, telescopic pipe put on this in pipe and adjust this Fixture for tube of seat this telescopic pipe is captiveed joint with last pipe, this moment, this first Shock absorber and second Shock absorber were the state that keeps flat, thereby this telescopic pipe and last pipe are reduced downwards, the function that here can fold like this, masculinity and femininity can both be got on or off the bus easily.

The specific embodiment

See also Fig. 1 to Fig. 4, a kind of folding frame for bicycle 1 comprises a pipe 12, once manages to manage on 14, one lower intermediate tube 16, a reinforcement pipe 18, the Chain stay 20, in 22, one telescopic pipe 24, the upper intermediate tube 26, and manage 28, one Seat stay 30, a hook 32, one first Shock absorber 34, one second Shock absorber 36, one the 3rd Shock absorber 38.

This time pipe 14 and head pipe 12 weld togethers, pipe 22 utilizes a rotating shaft 40 rotatable tops that are articulated in this time pipe 14 to close on this pipe 12 places on this.

Should go up pipe 22 inside is hollow, and its tube wall is provided with a Fixture for tube of seat 42 outward.

The upper end of this telescopic pipe 24 is inserted into pipe 22 inside on this, and this telescopic pipe 24 can stretch into the different distance in pipe 22 inside on this.Adjust this Fixture for tube of seat 42 and can make this telescopic pipe 24 stop to stretch, telescopic pipe 24 is captiveed joint with last pipe 22.

This upper intermediate tube 26 is welded in the lower end of this telescopic pipe 24.

This first Shock absorber 34 and second Shock absorber 36 are first group of Shock absorbers, and they install (see figure 2) side by side, the rotatable left and right sides that is articulated in these telescopic pipe 24 middle parts, their upper end, the rotatable two ends, the left and right sides that are articulated in this Seat stay 30, its lower end.

This Chain stay 20 is welded on the both sides of a five-way 44 respectively with this time pipe 14 and captives joint.

Second group of Shock absorber during the 3rd Shock absorber 38, the one end is rotatable to be articulated on this Chain stay 20, and its other end is rotatable to be articulated on this Seat stay 30, to 30 resilient supporting roles of this Seat stay.

This lower intermediate tube 16 is welded on this five-way 44, and this reinforcement pipe 18 is welded in this lower intermediate tube 16 and manages between 14 down.

This hook 32 is welded on this Chain stay 20, and this Seat stay 30 is screwed onto on this hook 32.

After this vehicle frame 1 assembled, integral installation was in a bicycle.Can adjust according to cyclist's sex during use, the male sex gets on the bus stride across seat behind car after, this telescopic pipe 24 and last pipe 22 can be in the higher positions, during adjustment telescopic pipe 24 being extracted out and adjust this Fixture for tube of seat 42 from this pipe 22 makes this telescopic pipe 24 captive joint with last pipe 22, this moment, this first Shock absorber 34 and second Shock absorber 36 were the upright state (see figure 2), thereby with this telescopic pipe 24 and last pipe 22 lifting upward; Stride across from the place ahead and get on the bus and the women generally is a leg, this telescopic pipe 24 and last pipe 22 must be at lower positions, form convenient for female getting on the bus of neutral gear ability, when adjusting, telescopic pipe 24 put on this in pipe 22 and adjust this Fixture for tube of seat 42 this telescopic pipe 24 is captiveed joint with last pipe 22, this moment, this first Shock absorber 34 and second Shock absorber 36 were the state (see figure 4) that keeps flat, thereby this telescopic pipe 24 and last pipe 22 are reduced downwards.

The utility model is by three shock absorbers 34,36,38 cooperatively interact and realized good shock-absorbing Effect; Review it, existing general folding frame for bicycle is only used a shock absorber, and no matter why one Improve shock-proof effect and all can't reach very good.
