Description

Foadable bicyle frame

Technical field

The utility model relates to a kind of bicycle rack, particularly a kind of Foadable bicyle frame.

Background technology

Existing Foadable bicyle frame, mostly being hinge-type connects, adopt folding bicycle inconvenient operation when folding of this connection mode, and folding back thickness is bigger, can only play the effect that certain reducing takies volume, conveniently lays, but its folding back structure is compact inadequately, and volume is still received not ideal enoughly folded, carries still very inconvenient.

The utility model content

The purpose of this utility model is to provide a kind of simple to operate when folding for the deficiency that solves above-mentioned technology, the Foadable bicyle frame of folding back compact overall structure.

The novel technical scheme that provides of this usefulness is: a kind of Foadable bicyle frame, comprise front fork tube, back breeches pipe, the seat pipe, first connecting rod and cant beam, front fork tube is provided with, following lug, seat pipe top is provided with lug, bottom-hinged is on back breeches pipe, back breeches pipe is made up of pipe and cell body, a latching device is equipped with on the top of pipe, in its bottom surface a connection piece is housed, one end of cell body is hinged on down on the lug, the termination of the other end is seated in the latching device, is installed with end lug in its bottom surface, and attaching parts is hinged on the end lug, on the cell body wall, be provided with pin-and-hole, the port place is provided with baffle plate thereon, and cant beam is by first connecting rod, second connecting rod and slide bar are formed, and an end of first connecting rod is hinged on the lug, the other end is hinged on an end of slide bar, the other end of slide bar is provided with middle lug, and on the lug, the other end was hinged on the upper lug during an end of described second connecting rod was hinged on.

The resulting Foadable bicyle frame of the utility model, vehicle frame can draw in, and the front and rear part of folding bicycle also can be drawn close mutually, reaching the purpose of final gathering folding bicycle, and simple to operate, folding rear cycle frame structure compactness, it is little to take up room.The movable junction of this Foadable bicyle frame each several part all can be locked by latching device as required, that is: cell body and pipe junction, cell body are provided with latching device, be used to lock its place, place device, make Foadable bicyle frame stable between each parts after opening and folding, the user can obtain better user and experience.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the folding back of a utility model view;

Wherein: lug, 8 cell bodies, 9 baffle plates, 10 pin-and-holes, 11 attaching partss, 12 latching devices in 1 slide bar, 2 front fork tubes, 3 back breeches pipes, 4 pipes, 5 first connecting rods, 51 second connecting rods, 6 cant beams, 7 lugs, 71 upper lug, 72 times lugs, 73 end lugs, 74.

The specific embodiment

In conjunction with the accompanying drawings patent of the present invention is further described below by embodiment.

As shown in Figure 1, a kind of Foadable bicyle frame, comprise front fork tube 2, back breeches pipe 3, seat pipe 4, first connecting rod 5 and cant beam 6, front fork tube 2 is provided with, following lug 72, seat pipe 4 tops are provided with lug 7, bottom-hinged is on back breeches pipe 3, described back breeches pipe 3 is made up of pipe 31 and cell body 8, a latching device 12 is equipped with on the top of pipe 31, this latching device 12 can both play the locking effect after Foadable bicyle frame is opened or be folding, make the vehicle frame of bicycle under the two states stable, manage 31 bottom surfaces a connection piece 11 is housed, an end of cell body 8 is hinged on down on the lug 72, the termination of the other end is seated in the latching device 12, the bottom surface of cell body 8 is installed with end lug 73, and attaching parts 11 is hinged on the end lug 73, is provided with baffle plate 9 at the upper port place of cell body 8.

Cant beam 6 is made up of first connecting rod 5, second connecting rod 51 and slide bar 1, one end of first connecting rod 5 is hinged on the lug 7, the other end is hinged on an end of slide bar 1, the other end of slide bar 1 is provided with the middle lug 74 of band bayonet socket 1, on the lug 74, the other end was hinged on the upper lug 71 during one end of second connecting rod 51 was hinged on.Bicycle rack is opened back shield 9 can prevent that slide bar 1 from skidding off from cell body 8.Be provided with pin-and-hole 10 on cell body 8 walls, slide bar 1 is provided with pin-and-hole 10 with second connecting rod 51 pivotallys attached one end, after Foadable bicyle frame is opened, 10 pairs of the pin-and-holes on slide bar 1 and the cell body 8 is used dowel fixes, makes the stationkeeping of slide bar 1 in cell body 8.

As shown in Figure 2, when Foadable bicyle frame folds, earlier the latching device on the back breeches pipe 3 12 is unclamped, pin on the cell body 8 is extracted, first connecting rod 5 is upwards carried, the front and rear part of Foadable bicyle frame is drawn close mutually, then slide bar 1 is pushed away downwards in income cell body 8, close up before and after the vehicle frame, with 12 lockings of the latching device on the back breeches pipe 3, the folding of Foadable bicyle frame finished, and front fork tube 2, second connecting rod 51 and front fork tube 2 also are in the same place like this, and the pipe 31 of seat pipe 4, first connecting rod 5 and back breeches pipe 3 also arrives together.Compact overall structure after the utility model Foadable bicyle frame folds and finishes, it is little to take up room, and is convenient for carrying.
