Abstract

The utility model discloses a portable folding bicycle. A folding joint is arranged on a main beam pipe of a front triangle of a bicycle frame; a rear triangle is articulated with the front triangle through a hinge axis; and a member is arranged on a middle pipe of the front triangle, wherein the member can lead the upper part of the rear triangle to push against the front triangle when the bicycle is unfolded. A storage rack is fixedly arranged on the rear triangle and is positioned above a rear bicycle wheel; and an auxiliary wheel capable of being folded and unfolded is arranged at the rear end of the storage rack. A mechanism capable of leading the rear triangle to rotate forward around the hinge axis to stop at a position is arranged on the main beam pipe; and the position where the rear triangle stops can lead three points of a front bicycle wheel, the rear bicycle wheel and the auxiliary wheel to land parallelly. The portable folding bicycle has the characteristics that the volume is small, thereby occupying small space after the bicycle is folded; meanwhile, people can walk the bicycle, and the two hands are not needed to move the bicycle, therefore, the portable folding bicycle is more convenient and labor-saving to use.

Description

A kind of portable folding bicycle

Technical field

The utility model relates to a kind of bicycle, relates in particular to a kind of portable folding bicycle.

Background technology

Common folding bicycle has a folding joint on the vehicle frame main beam pipe, vehicle frame can be realized doubling at this place, and front and back wheel is closed up, and folding back vehicle frame is outstanding, and as shown in Figure 1, volume is bigger, is not easy to carry.

Occur a kind of improved folding bicycle in recent years, as shown in Figure 2, on its car beam a folding joint is arranged, back vent and vehicle frame are hinged.The folding joint side-foldable can be passed through in the front portion of vehicle frame, and the back vent of car then can be around hinge axis 6a convolution forward, and this folded bicycle realizes that two places are folding, and volume after folding is less, as shown in Figure 3.

That above-mentioned several folding bicycle, its point of view are only paid attention to take up room after folding is little, be convenient to deposit, and has ignored the comfort feature that the carrying of folding back is carried.Move to another place from one behind the bicycle folding, the user must with the hands mention it, and it is also inconvenient so both to have wasted time and energy, and especially to some female consumers or age customer less than normal, it is more painstaking to use.

Summary of the invention

The technical problems to be solved in the utility model provide that a kind of volume after folding is less, storage is taken up an area of less and also folding after the portable folding bicycle that can push away walking, need not both hands mention.

For solving the problems of the technologies described above, the utility model adopts following technical scheme:

On the girder pipe of triangle folding joint is housed before a kind of portable folding bicycle, vehicle frame, Vee formation is hinged by the preceding triangle of hinge axis and this.Should before have on the middle pipe of triangle and when this bicycle launches, make this Vee formation top be resisted against member on this preceding triangle.Be fixed with shelf on this Vee formation, these shelf are positioned at the rear wheel top and the rear end is equipped with the accessory whorl that can draw in and open.This girder pipe is provided with and makes this Vee formation rotate the mechanism that rests in a position forward around hinge axis, and this position that this Vee formation is stopped makes 3 parallel landing of front and back wheel and this accessory whorl.

For above-mentioned portable folding bicycle, the member that this Vee formation top is resisted against on the preceding triangle is push rod or trip.

For above-mentioned portable folding bicycle, making this Vee formation rotate the mechanism that stops at a position forward around hinge axis is the recessed button that this bicycle folding can engage with the protruding button on the five-way when getting up.

For above-mentioned portable folding bicycle, making this Vee formation rotate the mechanism that stops at a position forward around hinge axis is the protruding button that this bicycle folding can engage with the recessed button on the five-way when getting up.

For above-mentioned portable folding bicycle, this accessory whorl can draw in and open automatically.

Above-mentioned portable folding bicycle also comprises the handlebar of the folding locking mode that adopts interlock.

For above-mentioned portable folding bicycle, have on the contact surface of the two ends, the T font left and right sides of the vertical rod of this handlebar and handlebar end, the left and right sides to be parallel to ground-surface conical insert.

For above-mentioned portable folding bicycle, when launching, this handlebar locks by the handle in the vertical rod of this handlebar.

Advantage and characteristics that technical solutions of the utility model are main are as follows:

Portable folding bicycle of the present utility model, both guaranteed volume after folding little, with the little characteristics in space, can realize pushing away again walking, need not move by both hands, thereby use more convenient laborsaving.

The specific embodiment

The main improvements of portable folding bicycle of the present utility model are: by the folding joint on the vehicle frame main beam pipe and with Vee formation articulated hinges axle, realize that two places are folding; The accessory whorl that can launch automatically and draw in is housed on the Vee formation, after folding, 3 parallel landing of front and back wheel and accessory whorl, the user can push away garage and walk.

Below, an embodiment of portable folding bicycle of the present utility model is described with reference to Fig. 4 to Fig. 8.

Shown in Figure 4 and 5, on the girder pipe 6 of triangle 1 folding joint 7 is housed before the vehicle frame, Vee formation 2 is hinged by hinge axis 10 and preceding triangle 1.Have the member 5 on the triangle 1 before when described bicycle launches Vee formation 2 tops being resisted against on the middle pipe of preceding triangle 1, member 5 can adopt the push rod form, also can adopt the trip form.Be fixed with shelf 3 on the Vee formation 2, shelf 3 can be fixed on the Vee formation 2 by the mode of welding, shelf 3 be positioned at rear wheel top and rear end install can launch automatically and draw in be used to support the accessory whorl 4 that bicycle is stood.Girder pipe 6 is provided with and makes Vee formation 2 rotate the mechanism that rests in a position forward around hinge axis 10, the position that Vee formation 2 is stopped make front and back wheel 8 with 9 with 4 three parallel landing of accessory whorl, this mechanism can be provided in a side of the recessed button 17 that can engage mutually with the protruding button 18 on the five-way 19 when bicycle folding gets up on the girder pipe 6, or is located at the protruding button 18 that can engage mutually with the recessed button 17 on the five-way 19 when bicycle folding gets up on the girder pipe 6.

State behind the portable folding bicycle vehicle frame folding of the present utility model is shown in Fig. 6 and 7, and recessed button 17 engages mutually with protruding button 18, and accessory whorl 4 launches, and with front vehicle wheel 8, rear wheel 9 common kiss the earths, the user catches hold of vehicle seat 20, can push away car load and move.

As far as possible little in order to guarantee folding back car load volume, handlebar 11 adopts the folding locking mode of interlock.As shown in Figure 8, left side handlebar 12 can fold with right handlebar 13 in relative vertical rod 15, have on the contact surface of the two ends, the T font left and right sides of vertical rod 15 and left and right sides handlebar 12 and 13 ends to be parallel to ground-surface conical insert 16, when guarantee using about handlebar relatively vertical rod 15 be moved or rotate.When launching, handlebar is locked by the handle in the vertical rod 15 14.

The folding bicycle that the utility model is so had both satisfied the comfort feature that can push away walking, carry after folding, and had guaranteed that again common folding bicycle volume after folding is little, had deposited the little characteristics that take up room.
