Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-4 This utility model provides a technical solution: A bicycle saddle backrest, the bicycle saddle backrest comprising: An adjustment mechanism is provided, which can adjust the tilt angle of the backrest 5 according to the rider's height. The adjusting mechanism includes a sleeve rod 8 and a sleeve 9. A hinge hole is formed at one end of the outer side of the sleeve 9, and a sliding groove 11 is formed inside the sleeve 9. A locking groove 12 is distributed at the edge of the sliding groove 11. A slider 13 is provided at one end of the sleeve rod 8. The slider 13 located at one end of the sleeve rod 8 is slidably installed inside the sliding groove 11 formed inside the sleeve 9. In the embodiments of this utility model, when it is necessary to adjust the tilt angle of the sleeve rod 8, one end of the sleeve 9 fitted onto one end of the sleeve rod 8 is rotated; and when it is necessary to adjust the length position of the sleeve rod 8 inside the sleeve 9, it is only necessary to make the slider 13 set at one end of the sleeve rod 8 slide displacement inside the groove 11 formed inside the sleeve 9. After the slider 13 moves to the designated position, one end of the slider 13 is locked inside the locking groove 12, so that the sleeve rod 8 with the appropriate position adjustment can be positioned and fixed. Please see Figure 4 In one embodiment of this utility model, the slider 13 includes a slider body 16, which is slidably mounted inside the slide groove 11. A guide wheel 19 is movably mounted on one end of the slider body 16 via a pin. A crank 15 is also provided on the pin at the axis of the guide wheel 19, and one end of the crank 15 is connected to a crank wheel 14. In addition, a positioning block 17 is also provided on the slider body 16. One end of the positioning block 17 is connected to the push block 20 via a compression spring 18. The push block 20 is T-shaped, and the protruding part of the push block 20 is located inside the axis of the compression spring 18. The edge of the push block 20 is hinged to the outer side of the crank 15 via an eccentric shaft 21. Please see Figure 2 In an embodiment of this utility model, for example, when the sleeve rod 8 is stretched and extended inside the sleeve 9, the slider body 16 slides along the groove 11 formed inside the sleeve 9, and the guide wheel 19, which is movably installed at one end of the slider body 16, rolls along the groove 11. When the sleeve rod 8 is stretched to the designated position inside the sleeve 9 and stops, the set crank plate 15 pushes the push block 20 to move under the elastic variable generated by the deformation of the compression spring 18. Since one end of the push block 20 is movably connected to the crank plate 15 through the eccentric shaft 21, the crank plate 15 will rotate when the push block 20 moves. When the crank plate 15 rotates, it will push the crank wheel 14 to rotate, so that the crank wheel 14 is locked in the locking groove 12 formed at the edge of the slide groove 11, causing the slider 13 to stop in the position inside the slide groove 11 and not easily loosening. Please see Figure 3 When it is necessary to restore the sleeve rod 8 to the initial state later, when the slider 13 set at one end of the sleeve rod 8 is pulled to the top position of the slide groove 11, the guide wheel 19 set at the end of the slide groove 11 rises a step on the inner wall of the slide groove 11. When the guide wheel 19 returns along the original path on the step, the guide wheel 19 rotates in the opposite direction, which will drive the crank plate 15 to rotate in the opposite direction. This causes the crank wheel 14 set at one end of the crank plate 15 to move in the opposite direction to adjust the angle position and disengage from the clamping crank groove 12. Finally, the sleeve rod 8 can move quickly inside the sleeve 9 to restore to the initial state. Please see Figure 1 In one embodiment of this utility model, the bicycle saddle backrest further includes: A T-shaped tube 1 is provided, on which a crank 7 is hinged and movably mounted. A backrest 5 is provided on one side of the upper end of the crank 7, and a shock-absorbing pad 6 is installed on the other side of the upper end of the crank 7. At the same time, a riser 10 is installed at the lower end of the T-shaped tube 1. One end of the sleeve 8 of the adjustment mechanism is connected to the middle position of the crank 7, and the lower end of the sleeve 9 of the adjustment mechanism is movably mounted on the riser 10. In an embodiment of this utility model, when a cyclist is riding, the cyclist's back rests against the surface of the unfolded backrest 5. The backrest 5 is composed of a foam covering and a dense outer skin, which can improve the comfort of the cyclist when using it. Meanwhile, the installation tilt angle of the backrest 5 can be adjusted through the set adjustment mechanism to make it suitable for riders of different heights; in addition, the backrest 5 can be laid flat in a straight line later to extend the rider's sitting space. Please see Figure 1 In one embodiment of this utility model, a saddle 2 is installed on the T-tube 1. The saddle 2 installed on the T-tube 1 is used to provide a sitting space for the rider. A tube 3 is provided on one side of the lower end of the T-tube 1. The tube 3 installed on the T-tube 1, the riser 10, and the entire T-tube 1 are integrally formed. The tube 3 and the T-tube 1 form a triangular cross section. Triangles have stability, so they can be used to improve the stability of the entire bicycle saddle backrest when it is installed. Meanwhile, positioning rings 4 are linearly arranged on the lower surface of the insertion tube 3; when assembling the bicycle saddle backrest, after the insertion tube 3 is inserted obliquely into the corresponding mounting hole of the bicycle, the bolts are inserted through the inner wall of the mounting hole and into the positioning rings 4 formed on the surface of the insertion tube 3 to fix the position of the entire bicycle saddle backrest on the bicycle. The working principle of the above-mentioned utility model is as follows: After the insertion tube 3 is inserted obliquely into the corresponding mounting hole of the bicycle, the bolt passes through the inner wall of the mounting hole and extends into the positioning ring 4 formed on the surface of the insertion tube 3 to fix the position of the entire bicycle saddle back on the bicycle. At the same time, based on the rider's height, the force is applied to the shock-absorbing pad 6, so that the backrest 5 can be adjusted and changed in tilt angle through the adjustment mechanism; Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
