Description

Adjustable angle bicycle seat cushion

The invention relates to a bicycle seat cushion adjustment structure, in particular to a bicycle seat cushion with adjustable angle.

Under the current trend of leisure activities, riding a bicycle to explore the mountains and rivers and scenery is one of the most popular ways at present. Therefore, bicycles are no longer just a simple means of transportation, which combines the effects of leisure and entertainment with sports and fitness. Nowadays, the leisure of riding a bicycle is very popular among the public.

In order to increase the riding comfort of general bicycles, the position and angle of the bicycle seat cushion can be adjusted according to the needs of the rider. For the assembly between the bicycle seat cushion and the seatpost, the common structure is , The lower clip clamps the seat bow of the seat cushion in the middle. At the same time, it is assembled with bolts and nuts to complete the lock and fixation of the overall structure. Therefore, the design structure of the bottom rod under the seat cushion must have better strength Requirements, especially for some types of vehicles that must directly bear the bumps of the road, because the bumps on the road are likely to cause fracture and bending, or the possibility of loosening the locking structure, so it is easy to cause the seat cushion to move or angle during the riding. Changes affect riding safety. In addition, in order to adjust, it causes troubles and troubles in the adjustment process.

In view of the above-mentioned shortcomings of conventional bicycle seat cushions, the inventors developed the present invention based on the idea of thinking and creation.

The present invention provides a bicycle seat cushion with an adjustable angle, comprising: a pole, a seat cushion and a locking unit, the seat pole has a number of tooth-shaped locking protrusions and a number of sliding grooves, and the seat cushion has A tooth-shaped engaging part and a number threading part. The locking convex part of the seat post cooperates with the seat cushion engaging part to be mutually engaged and assembled, and is used in conjunction with a locking member of the locking unit to pass through the number threading The seat post and the seat cushion are locked or loosened by a lock nut.

The main purpose of the adjustable-angle bicycle seat cushion of the present invention is to reduce the number of accessories, greatly simplify the structure, and make the assembly and angle adjustment of the seat cushion more convenient, and the purpose of quick and easy assembly and convenient angle adjustment.

The following further descriptions are provided in conjunction with the drawings of the preferred embodiments of the present invention, so that those who are familiar with the related technologies of the present invention can implement them based on the statements in this specification.
