Description

Technical Field

[0001] The utility model relates to the field of bicycle parts, in particular to a bicycle through-rod with an anti-torsion function. Background Art

[0002] In the structure of a bicycle, the through-stem, also known as the "seatpost," is a crucial component for supporting the rider's weight, directly impacting the riding experience and safety. However, conventional bicycle seatposts present some significant problems in practical use.

[0003] Especially under certain specific conditions, its performance defects gradually become prominent. In the cold winter, the drop in temperature will cause the physical properties of the seatpost material to change, resulting in a decrease in flexibility and an increase in brittleness. When the rider encounters bumpy roads, the seatpost, under the influence of the rider's weight and the instantaneous downward impact force, is prone to deformation, tilting, and may even break and damage due to its limited torsional resistance, posing a safety hazard to riding.

[0004] At the same time, everyday riding often involves impacts from various directions, such as lateral forces during sharp turns and the impact of unexpected collisions. Traditional bicycle stems struggle to effectively resist these impacts, making them susceptible to torsion and damage, leading to deformation.

[0005] Therefore, a bicycle through-bar with an anti-torsion function is proposed to solve the above problems. Summary of the Invention

[0006] In order to make up for the above shortcomings, the utility model provides a bicycle straight-through rod with anti-torsion function, which aims to improve the problem in the prior art that the straight-through rod is easily deformed or even broken when the seat post is used in winter and passes through bumpy roads.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a bicycle straight-through rod with anti-torsion function, including a seat post, a slot is provided on the outer wall of the seat post, a buffer assembly is provided at the top of the seat post, a reinforcement assembly is provided inside the seat post, the buffer assembly includes a connecting block, a sliding groove is provided at the top of the outer wall of the seat post, a cavity is provided on the inner wall of the connecting block, the inner wall of the connecting block is elastically connected to a sealing gasket through a compression spring, a circular hole is provided on the upper surface of the sealing gasket, and a mounting seat is provided on the outer wall of the connecting block.

[0008] Preferably, the reinforcement component includes a sponge pad, the inner wall of the bottom end of the seat post is fixedly connected to a round tube, and the inner wall of the round tube is fixedly connected to a reinforcing rib.

[0009] The slot of the puncture-resistant aluminum smoke machine passes through the lower surface of the seat rod, and the inner wall of the bottom end of the connecting block is provided with a protrusion.

[0010] The protrusion of the puncture-resistant range hood aluminum is slidably connected to the inner wall of the slide, and the protrusion fits the inner wall of the slide.

[0011] One end of the compression spring of the puncture-resistant range hood aluminum is fixedly connected to the inner wall of the top end of the connecting block, the other end of the compression spring is fixedly connected to the upper surface of the sealing gasket, and the sealing gasket piston is connected to the inner wall of the connecting block.

[0012] The lower surface of the puncture-resistant aluminum sealing gasket is fixedly connected to the upper surface of the seat post.

[0013] The upper surface of the puncture-resistant aluminum round tube is fixedly connected to the inner wall of the top end of the seat post, and the sponge pad is filled between the round tube and the seat post.

[0014] The puncture-resistant range hood aluminum reinforcement ribs are provided in multiple groups, and the multiple groups of reinforcement ribs are evenly distributed longitudinally and staggered with each other.

[0015] The utility model has the following beneficial effects:

[0016] 1. In this utility model, the buffer assembly significantly slows the impact when the seatpost is subjected to a longitudinal impact, effectively providing a buffer. This effectively mitigates the adverse effects of downward impact on the seatpost, reduces the possibility of seatpost deformation and damage, and mitigates safety hazards during riding.

[0017] 2. In the present invention, by strengthening the coordination of the components, the strength of the bicycle seat post can be effectively improved, and when facing the impact forces from all sides, it can also provide buffering, which can effectively avoid the probability of the seat post being damaged by the impact forces from all sides, and ensure the service life of the seat post.

[0018] 3. In the present invention, by strengthening the coordination of the components, the sponge pad can also insulate the round tube, thereby ensuring the toughness of the round tube during winter use and reducing the probability of damage to the seat post. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Reference Figure 1 - Figure 3 The reinforcement component includes a sponge pad 31. The inner wall of the bottom end of the seat post 1 is fixedly connected with a round tube 32. The round tube 32 is made of metal. The sponge pad 31 can provide insulation for the round tube 32. The inner wall of the round tube 32 is fixedly connected with a reinforcing rib 33. The reinforcing rib 33 can improve the strength of the round tube 32.

[0028] Reference Figure 1 、 Figure 2 、 Figure 4The slot 101 passes through the lower surface of the seat post 1, and the inner wall of the bottom end of the connecting block 21 is provided with a protrusion, which is slidably connected to the inner wall of the slide groove 201. The protrusion fits the inner wall of the slide groove 201 to maintain a seal. One end of the compression spring 23 is fixedly connected to the inner wall of the top of the connecting block 21, and the other end of the compression spring 23 is fixedly connected to the upper surface of the sealing gasket 24. The sealing gasket 24 piston is connected to the inner wall of the connecting block 21. When the connecting block 21 moves downward, it will approach the sealing gasket 24, and the compression spring 23 will also be squeezed. The sealing gasket 24 and the compression spring 23 are both located in the cavity 202. The cavity 202 is in a sealed state and is filled with hydraulic oil. The lower surface of the sealing gasket 24 is fixedly connected to the upper surface of the seat post 1.

[0029] Reference Figure 1 - Figure 3 The upper surface of the round tube 32 is fixedly connected to the inner wall of the top end of the seat post 1.

There are multiple groups of reinforcing ribs 33, and the multiple groups of reinforcing ribs 33 are uniformly distributed longitudinally and staggered with each other.

[0030] Working principle: The device is initially installed on a bicycle. During bicycle riding, if the bicycle passes through a bumpy road section, a longitudinal impact force is generated. The impact force will drive the bicycle seat, the mounting seat 22 and the connecting block 21 to move downward, and the connecting block 21 will move closer to the sealing gasket 24. During this process, the compression spring 23 will be squeezed to generate a reaction force, and the hydraulic oil in the cavity 202 in the connecting block 21 will be squeezed, and the hydraulic oil will pass through the circular hole 203. Since the aperture of the circular hole 203 is small, the flow rate of the hydraulic oil will be limited, thereby providing a buffering effect, reducing the impact transmitted to the seat post 1, avoiding the seat post 1 from twisting, deformation, and damage, and ensuring the stability of the seat post 1 during use.

[0031] In addition, during use, if the seat post 1 is subjected to impact force from all sides, the impact force will be transmitted to the sponge pad 31. The sponge pad 31 can provide buffering to prevent the seat post 1 and the round tube 32 from deformation, and the reinforcing ribs 33 can provide reinforcement for the round tube 32. The sponge pad 31 can provide heat preservation for the round tube 32 and ensure the toughness of the round tube 32 during use, thereby reducing the probability of damage to the seat post 1 and ensuring the service life of the seat post 1.
