The generally known link type shock absorber seatpost, as shown in the Taiwan Announcement No. M572852 Patent, is mainly used to swingably connect the two ends of an upper link and a lower link to a pipe and a cushion. Between the components, an elastic component is placed in the plug-in tube of a pipe, and then a tie rod is used to connect the lower connecting rod, so that the seat cushion can generate elasticity through the lower connecting rod, the tie rod and the elastic component The role of shock absorbers. However, installing the elastic component in the plug-in tube of the seat tube not only makes the overall structure more complicated, but also has the disadvantage that it is not easy to manufacture and assemble. In addition, the lower part of the seat tube integrally extends the structure of the plug-in tube, which will occupy more space during storage and increase inventory pressure. In particular, seat tubes of different bicycle frames need to be matched with socket tubes of different tube diameters. Therefore, it is necessary to produce seat tubes with socket tubes of different tube diameters for consumers to purchase in order to cope with changes in various specifications. , And this will not only increase production costs and be less economical, but also greatly increase inventory pressure.

The upper seat system can be combined with the bottom of a cushion and includes an upper pivot seat. The two connecting rods have a longitudinal rod and a transverse rod that are connected in an L shape, and are arranged oppositely from top to bottom and opposite to each other between the lower pivot seat and the upper pivot seat. The lower end and the upper end are respectively pivotally connected to the lower pivot seat and the upper pivot seat by four-axis pins. The elastic member is arranged between the two connecting rods, and the upper and lower ends of the two connecting rods respectively abut on the two transverse rods of the two connecting rods to provide elastic force for the swinging and resetting of the two connecting rods.

The connecting rod type shock absorber seat post provided by this creation is that the elastic member is arranged between the two connecting rods, and the upper and lower ends of the two connecting rods are respectively pressed against the two transverse rods of the two connecting rods to provide the swinging of the two connecting rods. The elastic force of the reset, therefore the structure is relatively simple, and the manufacture and assembly are also relatively easy, so that the manufacturing cost can be greatly reduced. In particular, with the structural design of the sleeve of the lower base body that can be used to bundle the plug-in pipes of different pipe diameters, the lower base body can choose to bundle the plug-in pipes of different pipe diameters according to the different specifications of customers. Take over, so the production is relatively simple, and only need to make a uniform specification of the lower seat body to match the plug-in tube of different pipe diameters to achieve the purpose of matching different specifications of the frame, without the need to produce several different specifications of the lower seat body, Therefore, the production cost is lowered and the economic efficiency is better. Moreover, it takes less space for rewinding and can greatly reduce inventory pressure.
