Detailed Description

In order to make the technical field better understand the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings and embodiments.

As shown in fig. 1 to 4, like the conventional bicycle, a bicycle convenient to disassemble includes a front wheel bracket 1, a rear wheel bracket 2, a front fork 3 connected to the front wheel bracket, a rear wheel 4 and a seat cushion 5 connected to the rear wheel bracket, a front vertical tube 201 arranged on the rear wheel bracket 2, and the seat cushion 5 arranged at the upper end of the front vertical tube 201; other parts of the bicycle that are identical to the structure of the prior bicycle are not described in detail herein.

The front wheel support is characterized by further comprising a fixing box 6 fixedly connected with the front vertical pipe 201 and a plug board 7 arranged at the rear end of the front wheel support 1, wherein the plug board 7 is detachably connected with the fixing box 6.

In this embodiment, the front wheel bracket 1 is made of a metal flat pipe.

At least one transverse groove 604 communicated with the inside of the fixed box is formed in each of the two side walls of the fixed box 6, and each transverse groove is provided with a bolt assembly 8; at least one connecting gap 701 is respectively arranged in the edges of the two sides of the plugboard 7; when the inserting plate 7 is inserted into the fixing box 6, the connecting notches 701 on both sides of the inserting plate are respectively aligned with the transverse slots 604 on the fixing box, and the bolts 801 on the bolt assemblies 8 pass through the transverse slots 604 and the connecting notches 701 to connect the fixing box 6 with the inserting plate 7.

The fixing box 6 of the present embodiment is formed by integrally molding a bottom plate 601, two side plates 602, and a cover plate 603, wherein a longitudinal gap 603a is provided in the cover plate; in order to make the connection between the fixing box 6 and the inserting plate 7 more stable, two transverse grooves 604 are respectively arranged in two side walls of the fixing box 6; two connecting notches 701 corresponding to the positions of the transverse grooves are respectively arranged in the edges of the two sides of the plugboard. The fixing case 6 has the above structure, and both ends thereof are provided with openings 605. It should be noted that two transverse slots 604 are respectively arranged in two side walls of the fixed box 6, and two connection notches 701 corresponding to the positions of the transverse slots are respectively arranged in two side edges of the plugboard, which is just a preferred embodiment, and it is obvious that even if one transverse slot 604 is respectively arranged in two side walls of the fixed box 6 and one connection notch 701 corresponding to the position of the transverse slot is respectively arranged in two side edges of the plugboard, the requirement that the plugboard 7 and the fixed box 6 can be detachably connected can be met.

The bolt assembly 8 includes a bolt 801, a fixing nut 802 disposed at one end of the bolt, and a rotating handle 803 sleeved on the bolt and in threaded connection with the bolt.

The rotating handle 803 is positioned outside the transverse slot 604; when the fixing box 6 is fixedly connected with the plug board 7, the fixing nut 802 abuts against the cover plate 603, and the rotating handle 803 abuts against the bottom plate 601.

Here, the outside opening of the transverse groove 604 should be smaller than the diameter of the bolt 801 to prevent the bolt from coming out of the opening of the transverse groove.

In the use state, the plug board 7 is positioned in the fixed box 6, and the plug board 7 is connected with the fixed box 6 through the bolt assembly 8; when the bicycle needs to be disassembled, the rotating handle 803 is unscrewed and taken down, the bolt and the fixing nut 802 integrally formed with the bolt are simultaneously taken down, the plugboard 7 is moved and taken out from one opening of the fixing box 6, the longitudinal gap 603a in the cover plate 603 can be used for the connecting end of the front wheel bracket 1 connected with the plugboard 7 to pass through, the disassembly of the front wheel bracket 1 and the rear wheel bracket 2 can be realized, and the bicycle is disassembled into two parts, so that the bicycle is convenient to package, store and transport. The assembly process is the reverse of the disassembly process. The separable connection means that the plugboard and the fixed box can be fixedly connected and can be detached according to requirements, and the disassembly and assembly process is simple.

After the front wheel bracket 1 and the parts fixedly connected with the front wheel bracket 1, the rear wheel bracket 2 and the parts fixedly connected with the rear wheel bracket are disassembled into two parts, the connection between the two parts is only left for controlling the brake cable of the rear wheel, the brake cable is generally made of flexible objects such as steel wire ropes and the like, so that the placement of the two parts is not influenced, and the packaging and the transportation are convenient.
