Chain-free type three wheel rowing bicycle seat pad shock absorbing structure

Abstract

The invention relates to a chain-free type three wheel rowing bicycle seat pad shock absorbing structure and discloses a seat pad shock absorbing structure due to which, the hip of a rider can slide back and forth on a seat pad, and adjustment can be performed for shock absorbing according to the action relationship of the rider. Shock absorbing is performed through a shock absorbing ring sleeve,and the shock absorbing effect can be adjusted by changing a clamping point. The structure is simple, the mass is small, and maintaining and replacing are convenient. The structure is characterized inthat a base fixing block is placed on a base supporting frame; the two sides of the base supporting frame are each provided with a slide groove; the width of each slide groove is gradually increasedfrom inside to outside; the upper side face of the base fixing block is a bevel, and the upper side face is provided with two semicircular grooves; a base fastening block is placed on the base fixingblock, and the middle portion is connected with the base fixing block through a fastening screw; and the lower side face of the base fastening block is a bevel, and is attached to the upper side faceof the base fixing block.

Description

technical field [0001] The invention relates to a seat cushion vibration-reduction structure of a chainless three-wheeled rowing bicycle, which relates to a seat cushion vibration-reduction buffer structure used on a chainless three-wheeled rowing bicycle, and belongs to the field of vehicle equipment. In particular, it relates to a cushion damping structure that can not only allow the rider's buttocks to slide back and forth on the seat cushion, but also adjust the shock absorption according to the rider's action relationship. Background technique [0002] The traditional chained bicycle drives the wheel disc installed on the central shaft to rotate by stepping on the pedal, and drives the flywheel on the rear axle of the bicycle through the chain, and at the same time, the flywheel drives the rear wheel of the bicycle for transmission, so as to realize the transportation function of the bicycle. Although the structure of the chain-type bicycle on the Internet is simple, th...

Problems solved by technology

[0005] The existing seat cushion has a single structure, and its main function is support and shock absorption. When it is used on a rowing bicycle, the rider's buttocks cannot slide on the seat cushion. The posture makes the bicycle move forward, because the complex road conditions lead to the overall vibration of the bicycle, using the existing bicycle seat, the rider will feel uncomfortable on the seat cushion of the rowing bicycle for a long time, and the experience comfort is poor
