[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The utility model provides Figure 1-5 The bicycle seat adjustment structure shown in the figure includes a frame body 1 and a slider base 2 installed above the frame body 1, a slide groove 3 is provided on both sides of the slider base 2, and sliders 4 are slidably connected to the inside of the two slide grooves 3, a connecting plate 7 is provided between the two sliders 4, the top of the connecting plate 7 is fixedly connected to the support rod 5, and a detachable seat cushion 6 is provided above the support rod 5, a clamping device is provided inside the connecting plate 7 to prevent the connecting plate 7 from moving up and down and shaking, a guide device is provided inside the connecting plate 7 to limit the up and down movement of the connecting plate 7, a claw 14 is fixedly connected to the bottom end of the connecting plate 7, and a stepped protrusion 15 is provided at the bottom of the slider base 2, and a groove adapted to the claw 14 is provided inside the protrusion 15;

[0020] By locking the claw 14 in the protrusion 15, the seat cushion 6 can be prevented from sliding down after long-term use. Then, the claw 14 is driven upward by lifting the connecting plate 7, so that the claw 14 is separated from the protrusion 15. Then, the connecting plate 7 drives the two sliders 4 to move left and right in the slide groove 3 through the clamping device, and then the claw 14 is clamped in the corresponding protrusion 15, thereby adjusting the height of the seat cushion 6.

[0021] like Figure 1 As shown, the upper and lower inner walls of the two chutes 3 are fixedly connected with a baffle 31, the two sliders 4 are adapted to the chutes 3, and the two sliders 4 are both convex in shape. The cooperation between the baffle 31 and the slider 4 can limit the movement of the slider 4 in the chutes 3 and prevent the slider 4 from escaping from the chutes 3.

[0022] like Figure 1 and Figure 2 As shown, the top end of the support rod 5 is fixedly connected to a mounting plate 51, and the top end of the mounting plate 51 is connected to the bottom end of the seat cushion 6 by screws. The mounting plate 51 is screwed to the seat cushion 6, so that the seat cushion 6 can be easily replaced.

[0023] like Figure 5As shown, the guide device includes a guide rod 8, one end of which is welded to one of the sliders 4, and a guide groove 9 adapted to the guide rod 8 is provided inside the connecting plate 7. The guide rod 8 is horizontally inserted into the guide groove 9. When the guide rod 8 is horizontally inserted into the guide groove 9, the connecting plate 7 drives the guide groove 9 to move upward, so that the upward movement direction of the connecting plate 7 is fixed, and at the same time, the connecting plate 7 can be prevented from driving the claw 14 to flip.

[0024] like Figure 5 As shown, a second guide groove 13 adapted to the threaded rod 11 is provided below the receiving hole 10 , and the receiving hole 10 is communicated with the second guide groove 13 , so that the threaded rod 11 has enough space to move downward when it moves downward.

[0025] like Figure 5 As shown, the clamping device includes a receiving hole 10 opened inside the connecting plate 7, and a clamping spring 12 is fixedly connected to the upper inner wall of the receiving hole 10. A threaded rod 11 is connected through one of the sliders 4, and one end of the threaded rod 11 is threadedly connected to the other slider 4. The threaded rod 11 is adapted to the clamping spring 12. By fixing the clamping spring 12 inside the receiving hole 10 and clamping the clamping spring 12 with the threaded rod 11, the connecting plate 7 can be fixed, and then the seat cushion 6 can be fixed.

[0026] Working principle of the utility model: when in use, when the seat height needs to be adjusted, first lift the seat cushion 6, and the movement of the seat cushion 6 drives the mounting plate 51 to move up, and the upward movement of the mounting plate 51 drives the support rod 5 to move up, and the upward movement of the support rod 5 drives the connecting plate 7 to move up, and the upward movement of the connecting plate 7 drives the retaining spring 12 to move up, and the upward movement of the connecting plate 7 drives the guide groove 9 to move up, because the guide rod 8 is horizontally inserted in the guide groove 9, the upward movement route of the guide groove 9 is fixed, preventing the connecting plate 7 from shifting upward, and thus The threaded rod 11 moves downward along the inside of the second guide groove 13, and the claw 14 moves upward by moving the connecting plate 7 upward, so that the claw 14 disengages the groove portion of the protrusion 15, and then the guide groove 2 13 is driven to move by moving the connecting plate 7 left and right, so that the guide groove 2 13 squeezes the threaded rod 11 and drives the two sliders 4 to move in the slide groove 3. The height can be adjusted by inserting the claw 14 into the corresponding protrusion 15 according to the required height, and finally, the seat cushion 6 is pressed so that the threaded rod 11 is squeezed into the retaining spring 12.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
