[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figures 1 to 7 As shown, a bicycle seatpost with shock absorption function includes a seatpost body 1, a seatpost mounting head 2, a shell assembly 3 and a shock absorption assembly 4. The seatpost mounting head 2 is installed at one end of the seatpost body 1, the shock absorption assembly 4 is installed at the other end of the seatpost body 1, and the shell assembly 3 is installed on the outside of the seatpost body 1.

[0032] The outer shell assembly 3 includes an upper outer shell 31, a lower outer shell 32, a sliding sleeve 33, and a base 34. The upper outer shell 31 and the lower outer shell 32 are both sleeved to the outside of the seat tube body 1. The upper outer shell 31 is sleeved to one end of the lower outer shell 32 through the sliding sleeve 33. The base 34 is installed at the other end of the lower outer shell 32. A hollow cavity is formed between the other end of the lower outer shell 32 and the base 34, and the shock absorption assembly 4 is located inside the hollow cavity.

[0033] The upper outer shell 31 and the lower outer shell 32 are axially provided with a number of rows of limiting holes 311. The sliding sleeve 33 is provided with a number of limiting blocks 331 corresponding to each row of limiting holes. The limiting blocks 331 are used in conjunction with the limiting holes 311. The number of limiting blocks 331 corresponds one-to-one with the number of limiting holes 311.

[0034] The shock absorption component 4 is an MD-type spring-type shock absorber or an MDU glue stick. In this embodiment, the purpose of setting the limiting hole 311 is to facilitate the injection of glue into the limiting hole 311 when installing the upper outer shell 31, thereby increasing the connection stability between the upper outer shell 31 and the seat tube body 1 (without interfering with the lifting and lowering of the seat tube body 1). In actual use, the seat tube body 1 is an existing lifting seat tube structure. The upper outer shell 31 and the lower outer shell 32 can be slid and fixed by external limiting components, and the sliding and fixing of the upper outer shell 31 and the lower outer shell 32 is also an existing mature lifting seat tube structure component.

[0035] This bicycle seatpost can achieve shock absorption by setting shock absorption component 4. Moreover, the shock absorption component 4 of this application has two options: shock-absorbing spring and shock-absorbing rubber rod. In addition, the outer shell component 3 of this bicycle seatpost can be stably installed on the seatpost body 1, which not only protects the seatpost body 1, but is also durable and highly practical.

[0036] In a preferred embodiment of this utility model, the number of columns of the limiting holes 311 is four, and the number of limiting holes 311 in each column is three. In actual use, the number of columns and the number of limiting holes 311 can be determined according to the actual situation.

[0037] In a preferred embodiment of this utility model, the sliding sleeve 33 is made of plastic material, which facilitates the fitting of the sliding sleeve 33 onto the upper outer shell 31.

[0038] In a preferred embodiment of this utility model, the outer side of the sliding sleeve 33 is provided with a plurality of protrusions 332, and the inner side of the lower outer shell 32 is provided with a plurality of grooves 321. The protrusions 332 and the grooves 321 are used in conjunction. In actual use, the sliding between the upper outer shell 31 and the lower outer shell 32 can be realized by the sliding of the protrusions 332 and the grooves 321, thereby avoiding interference with the lifting and lowering of the seat tube body 1.

[0039] In a preferred embodiment of this utility model, when the shock-absorbing component 4 is an MD-type spring-type shock absorber, the shock-absorbing component 4 further includes a shock-absorbing sleeve 41. Several retaining strips 411 are axially arranged on the outer side of the shock-absorbing sleeve 41. The retaining strips 411 cooperate with the grooves 321. In actual use, the protrusions 332 slide with one end of the grooves 321, and the retaining strips 411 slide with the other end of the grooves 321. In this embodiment, the material of the shock-absorbing sleeve 41 can also be a flexible plastic material, thereby avoiding interference with the vibration reduction of the MD-type spring-type shock absorber.

[0040] It should be noted that this application does not improve the manual lifting mechanism of the seat post; manual lifting of the seat post is existing technology. This application only improves the vibration reduction and stability of the seat post.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
