Abstract
The utility model relates to a folding bicycle frame, comprising an upper pipe, a lower pipe, etc. The frame is divided to front and rear two portions which are folded by making a middle pin shaft as a reaming point. Front and rear wheels are made to mutually partially depart after being folded to implement superposition for the incline of a pin. Meanwhile, a sitting saddle pipe can be retracted in the upper pipe, thus the whole vehicle can be provided with minimal folding volume after being folded. Furthermore, the folding velocity is fast, the structure is simple and the weight is light.
Description
The utility model belongs to the structure field of cycle frame.
The existing cycle frame of amounting to, exist amount to after, promptly receive little after, volume is excessive, launches, amounts to weakness such as process complexity, is difficult to find a kind of satisfied especially structure.
The purpose of this utility model is improved above-mentioned the deficiencies in the prior art part exactly, a kind of expansion is provided, amounts to quick and conveniently, simple in structure, and the vehicle frame of minimum volume is arranged after amounting to.
The utility model is achieved by the following technical solution: in Fig. 1, the vehicle frame part is two parts before and after the boundary is divided into pin 11 (rotating shaft).The pipe of going up of leading portion is one with first pipe weldering, on manage and respectively have the rear end of an iron plate 6, two iron plates to link to each other about the below, rear end, play position-limiting action; Trailing portion by under manage 7, five-way 8 and back vent are formed one, wherein the pipe front end has a cross-drilled hole down, this hole is connected with hole on the iron plate by pin 11, the front and back wheel axle center is equal or approaching equal to pin 11 distances, and whole vehicle frame is a hinge with pin 11, and front and back can be amounted to, wherein selling 11 is that certain bevelled is arranged, be that its axle center is not the general state vertical with the vertical plane of vehicle frame, exactly because like this, when amounting to, front and back wheel just can about open partially, could realize that front and back wheel overlaps.
The utility model is described in further detail below in conjunction with drawings and Examples:
Running condition structural representation when Fig. 1 is the utility model expansion,
Fig. 2 is the structural representation of the utility model when amounting to,
Among the figure, pipe, 6 iron plates, 7 times pipes, 8 five-ways, 9 trailing wheels, 10 are sat saddle pipe, 11 pins, 12 folder on 1 standpipe, 2 front-wheels, 4 poles, 5
For standpipe can be amounted to, be provided with a folder 12 in its position near first pipe.Pole 4 is to establish in order to stand firm after amounting at car load, and it is connected with folder top.
Amount to step: one, open the quick detach switch on the folder 12.Two, a pin slams trailing wheel, up carries the seat bag and can amount to, and in order to pack or minimum car load volume to be arranged in case of necessity, sits saddle pipe and can manage the inside in the indentation, and in addition, pole 4 also can be designed to removable moving.
From the above, by such body frame structure for automotive, having reached expansion, amounted to quick and conveniently, minimum volume is arranged after amounting to, is a kind of novelty, practical convertible cycle frame.
Claims (5)
1, a kind of convertible cycle frame, by last pipe 5, manage 7 down, five-way, roller pin 11 etc. form, wherein go up pipe and be one with first pipe weldering, following pipe, five-way, the same weldering of back vent are one, it is characterized in that: vehicle frame is two parts before and after the boundary is divided into pin 11, and these two parts are that hinge is amounted to pin 11.
2, vehicle frame according to claim 1 is characterized in that: the axle center of pin 11 is not vertical with the vertical plane of vehicle frame, but certain inclination is arranged.
3, vehicle frame according to claim 1 is characterized in that: the axle center of front and back wheel is to equate or approaching equating to the distance of pin 11.
4, vehicle frame according to claim 1 is characterized in that: standpipe folder top is provided with a pole.
5, vehicle frame according to claim 1 is characterized in that: sit saddle pipe and can manage the inside in the indentation.
