Description

Technical Field

[0001] The utility model relates to the technical field of the production of the frame vertical pipe, in particular to a frame vertical pipe structure with a water-drop-shaped cross section. Background Art

[0002] Due to manufacturing and technological conditions, the traditional folding bicycle vertical pipe is usually cylindrical. When the cyclist rides at high speed, the vertical pipe part serves as the front part of the bicycle. The existing contact area between the vertical pipe and the wind is relatively large, resulting in the wind blowing on the vertical pipe not being able to be dissipated in time, thus generating a large wind resistance. Riding with a large wind resistance will cause the rider to consume more energy, and long-term riding will cause rider fatigue, further affecting the riding effect of the bicycle. Therefore, a frame vertical pipe structure with a water-drop-shaped cross section is proposed to solve the above problems. Summary of the Invention

[0003] The purpose of the utility model is to provide a frame vertical pipe structure with a water-drop-shaped cross section in order to solve the above problems.

One end of the straight pipe is fixedly connected with a semi-circular clamping ring, and the other end is fixedly connected with a fixing ring two. A fixing member is arranged on the semi-circular clamping ring.

[0006] A fixing ring one is arranged on one side of the fixing ring two. A plurality of wind guiding grooves are evenly arranged on the front end face of the fixing ring one. A connecting member acting on the fixing ring one is arranged on the fixing ring two.

[0007] Preferably, the fixing ring one is composed of a connecting rod and annular clamping blocks arranged at both ends of the connecting rod, and the front end face of the annular clamping block is in a raindrop shape structure.

[0008] Preferably, a plurality of wind guiding holes are evenly arranged on the side faces of the fixing ring one and the fixing ring two.

[0009] Preferably, a plurality of annular installation grooves are evenly arranged in the fixing ring one and the fixing ring two, and annular reinforcing ribs are arranged in the annular installation grooves.

[0010] Preferably, the connecting member includes a plurality of connecting blocks one symmetrically arranged on the fixing ring two, positioning bolts arranged on the connecting blocks one, and a plurality of connecting blocks two symmetrically arranged on the fixing ring one. A circular hole matching with the positioning bolt is arranged on the connecting block two, and a nut is threadedly connected to one end of the positioning bolt.

[0011] Preferably, the fixing member includes connecting plates symmetrically arranged on the semi-circular clamping ring. A plurality of threaded holes are evenly arranged on the connecting plates, and fixing bolts are threadedly connected in the threaded holes.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0013] By using the raindrop-shaped fixing ring 1, the wind resistance coefficient of the riser is reduced, thereby effectively saving the energy of long-distance cyclists; by using the wind guide groove, it is convenient for the wind to pass through, slowing down the wind resistance on the riser, thereby reducing the wind resistance and saving the energy of long-distance cyclists; by using the wind guide holes, it is convenient for the wind on the sides of the fixing ring 1 and the fixing ring 2 to pass through, thereby reducing the wind resistance on the sides of the riser and being beneficial to the cycling of the cyclist.

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0021] A frame riser structure with a water droplet-shaped cross-section, including a straight pipe 1, one end of the straight pipe 1 is fixedly connected with a semi-circular snap ring 2, the other end is fixedly connected with a fixing ring 2 8, and a fixing member is provided on the semi-circular snap ring 2; by using the fixing member, it is convenient to fix the riser on the frame;

[0022] A fixing ring II 8 is provided with a fixing ring I 4 on one side. A plurality of air guiding grooves 3 are evenly formed on the front end face of the fixing ring I 4. By using the air guiding grooves 3, it is convenient for air to pass through, thereby reducing the air resistance and saving the energy of long-distance cyclists. A connecting member acting on the fixing ring I 4 is provided on the fixing ring II 8. By fixing the handle in the vertical pipe, the installation of the handle and the frame is realized.

[0023] In the present utility model, the fixing ring I 4 is composed of a connecting rod and annular clamping blocks arranged at both ends of the connecting rod, and the front end face of the annular clamping block is in a raindrop shape. By using the raindrop-shaped fixing ring I 4, the wind resistance coefficient of the vertical pipe is reduced, thereby effectively saving the energy of long-distance cyclists.

[0024] In the present utility model, a plurality of air guiding holes 9 are evenly formed on the side faces of the fixing ring I 4 and the fixing ring II 8. By using the air guiding holes 9, it is convenient for the air on the side of the fixing ring I 4 and the fixing ring II 8 to pass through, thereby reducing the wind resistance on the side of the vertical pipe and being beneficial to the cycling of cyclists.

[0025] In the present utility model, a plurality of annular installation grooves are evenly formed in the fixing ring I 4 and the fixing ring II 8, and annular reinforcing ribs 13 are arranged in the annular installation grooves. By using the annular installation grooves and the annular reinforcing ribs 13 in cooperation, it is convenient to improve the strength of the fixing ring I 4 and the fixing ring II 8, thereby improving the strength of the vertical pipe and further improving the service life of the vertical pipe.

[0026] In the present utility model, the connecting member includes a plurality of connecting blocks I 6 symmetrically arranged on the fixing ring II 8, a positioning bolt 10 arranged on the connecting block I 6, and a plurality of connecting blocks II 7 symmetrically arranged on the fixing ring I 4. A circular hole matching with the positioning bolt 10 is formed on the connecting block II 7, and a nut 5 is threadedly connected to one end of the positioning bolt 10. Among them, the cooperation of the positioning bolt 10 and the nut 5 can fix the fixing ring I 4 on the fixing ring II 8. At the same time, the positioning bolt 10 can also position the fixing ring I 4, facilitating the coincidence of the fixing ring I 4 and the fixing ring II 8, thereby facilitating the rapid installation of the fixing ring I 4.

[0028] Working principle: When the present utility model is in use, during the installation of the vertical pipe, first fix the semi-circular clamping ring 2 on the frame through the fixing bolts 12, then place the handle in the fixing ring II 8, and pass the connecting block II 7 on the fixing ring I 4 through the positioning bolt 10 to realize the clamping between the fixing ring I 4 and the fixing ring II 8. Finally, fix the handle between the fixing ring I 4 and the fixing ring II 8 with the nut 5 to realize the installation of the handle.

[0029] When riding a bicycle, since the front end of the seat tube is raindrop-shaped, it will reduce the wind resistance. Then, by using the wind guide groove 3, the wind blowing on the seat tube can be guided away, thereby reducing the wind resistance coefficient during bicycle riding and effectively saving the energy of long-distance cyclists.
