Description

Technical Field

[0001] This utility model relates to the field of saddle tube angle adjustment technology, and more specifically, to a saddle tube angle adjustment device. Background Technology

[0002] The saddle tube is an important component in bicycles and other vehicles. It is mainly used to connect the saddle to the frame and allows riders to adjust the angle and height of the saddle as needed. The design of the saddle tube usually takes into account the tightness of the connection, the ease of installation, and the performance of withstanding high pressure and high temperature environments. With the saddle tube angle adjustment device, riders can easily adjust the position of the saddle to obtain a more comfortable riding experience. As a key component connecting the saddle to the frame, the saddle tube plays an important role in the comfort and safety of bicycles.

[0003] A search revealed that publication number CN221163100U discloses a double-bolt adjustable seatpost with convenient stroke adjustment. This adjustable seatpost includes: an inner adjustable saddle tube, a fixed outer tube, an angle adjustment mechanism, and a saddle. The upper end of the inner adjustable saddle tube is connected to the saddle via the angle adjustment mechanism, and the lower end of the inner adjustable saddle tube is inserted into the fixed outer tube. The inner adjustable saddle tube can slide axially relative to the fixed outer tube while remaining circumferentially fixed. This adjustable seatpost uses a first bolt and a handle, both fitted around a pin, to achieve convenient and quick stroke adjustment without sacrificing riding comfort. The inventors discovered the following problems with the existing technology during the development of this invention:

[0004] Existing bicycles can be adjusted in height to accommodate different riders, but the angle between the saddle tube and the seat cannot be adjusted. When riding over different slopes, the seat remains at the same angle, which can compress the pubic bone and easily cause prostate problems.

[0005] Therefore, a saddle tube angle adjustment device is proposed to address the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] As attached Figures 1 to 6 The saddle tube angle adjustment device shown includes a saddle tube 1, a fixing component 2, an adjusting component 3, a limiting component 4, and a connecting pipe 5. The connecting pipe 5 is installed on the outer diameter of the saddle tube 1, and the limiting component 4 is sleeved on the outer diameter surface of the connecting pipe 5. The adjusting component 3 is installed on the top of the saddle tube 1, and the fixing component 2 is installed on both sides of the adjusting component 3.

[0026] Specifically: Before climbing a hill or adjusting the angle between the saddle tube 1 and the seat cushion, pull the pull ring 18 to move the fixing post 14, then make the fixing hole 13 coincide with the positioning hole 12 at different angles, and then release the pull ring again, so that the retraction spring 15 can move the fixing post 14 to fix it again. This device is easy to operate and the angle can be adjusted without the aid of tools during riding.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 6 As shown below, see details:

[0029] In a preferred embodiment, the adjustment assembly 3 includes a fixed mounting block 6, a fixed plate 7, a rotating shaft 8, a rotating plate 9, a rotating frame 10, a connecting block 11, a positioning hole 12, and a fixing hole 13. The fixed plate 7 is installed above the mounting block 6, and the rotating plate 9 is installed between the two sets of fixed plates 7. The connecting block 11 is installed above the rotating plate 9, and the rotating frame 10 is installed on the top of the connecting block 11. The fixed plate 7 and the rotating plate 9 each have a positioning hole 12 on one side, and the rotating frame 10 has fixing holes 13 on both sides. The rotating shaft 8 is provided through the outer surface of the rotating frame 10. When the seat cushion needs to be adjusted, simply pull out the fixing post 14, and adjust the rotating frame 10 so that the rotating frame 10 and the rotating plate 9 rotate on the rotating shaft 8, so that the fixing hole 13 on the outer wall of the rotating frame 10 overlaps with the positioning hole 12 on the outer wall of the fixed plate 7 and the rotating plate 9. Then, the fixing post 14 fixes and positions the fixing hole 13 and the positioning hole 12.

[0030] In a preferred embodiment, the fixing assembly 2 includes a fixing post 14, a contraction spring 15, a fixing frame 16, a limiting piece 17, and a pull ring 18. The contraction spring 15 is installed on the outer diameter of the fixing post 14, and the fixing frame 16 is installed on one end of the contraction spring 15. The limiting piece 17 is installed on one end of the fixing post 14, and the pull ring 18 is installed on the side of the limiting piece 17 away from the fixing post 14. By pulling the pull rings 18 on both sides, the pull rings 18 drive the fixing post 14 to move outward. Since one end of the contraction spring 15 is fixed to the outer wall of the fixing post 14 and the other end is fixed inside the fixing frame 16, when the pull rings 18 on both sides are pulled, the contraction spring 15 will move and extend and retract inside the fixing frame 16 with the fixing post 14. When the fixing post 14 is disengaged from the positioning hole 12, the fixing hole 13 is overlapped with the positioning hole 12 by adjusting the rotating frame 10 to drive a suitable angle. At this time, the pull ring 18 is released, the stress is released by the contraction spring 15, and the fixing post 14 is driven to re-enter the positioning hole 12 for fixing.

[0031] In a preferred embodiment, the limiting component 4 includes a bolt 19, a nut 20, and a limiting groove 21. The bolt 19 is installed on the inner wall of the limiting groove 21, and a nut 20 is installed on one end of the bolt 19. The height of the saddle tube 1 can be adjusted by locking the bolt 19 and the nut 20 in the limiting groove 21 at different heights.

[0032] In a preferred embodiment, the positioning holes 12 are arranged in a circular array with the rotation shaft 8 as the center. The fixing plate 7 is symmetrical about the rotation plate 9 and is provided in two sets. The multiple sets of positioning holes 12 facilitate better division of angles to adapt to different scenarios. The two sets of fixing plates 7 increase the connection strength.

[0033] In a preferred embodiment, the fixing post 14 and the fixing hole 13 form an engaging structure. The limiting component 4 is symmetrical about the center of the rotating plate 9 and is provided in two sets. The fixing frame 16 is fixed on one side of the rotating frame 10, so that the fixing post 14 can move with the fixing hole 13 and slide within the fixing hole 13.

[0034] The working process of this utility model is as follows: Before climbing a slope or adjusting the angle between the saddle tube 1 and the seat cushion, pull the pull ring 18 to move the fixing post 14, then make the fixing hole 13 coincide with the positioning hole 12 at different angles, and then release the pull ring 18 to make the compression spring 15 move the fixing post 14 to be fixed again. This device is simple to operate and can complete the angle adjustment without the aid of tools during riding. First, pull the pull rings 18 on both sides to move the fixing post 14 outward. Since one end of the compression spring 15 is fixed to the outer wall of the fixing post 14 and the other end is fixed to the inside of the fixing frame 16, when the pull rings 18 on both sides are pulled, the compression spring 15 will move and extend and retract inside the fixing frame 16 with the movement of the fixing post 14. When the fixing post 14 moves, the compression spring 14 will move and retract. 4. When disengaging from the positioning hole 12, the rotating frame 10 is adjusted to drive a suitable angle so that the fixing hole 13 overlaps with the positioning hole 12. At this time, the pull ring 18 is released, and the stress is released by the contraction spring 15, which drives the fixing column 14 to re-enter the positioning hole 12 for fixing. The bolt 19 and nut 20 are locked in the limiting groove 21 at different heights to achieve the height adjustment of the saddle tube 1. Multiple sets of positioning holes 12 facilitate better division of angles to adapt to different situations. The two sets of fixing plates 7 increase the connection strength. The fixing frame 16 is fixed on one side of the rotating frame 10, so that the fixing column 14 can move with the fixing hole 13 and slide in the fixing hole 13. The above is the working principle of this saddle tube angle adjustment device.
