Detailed Description
Referring to fig. 1 to 2, a specific structure of a preferred embodiment of the present invention is shown, which includes a seat frame body 10.
The seat tube frame body 10 is made of carbon fiber, and has high strength and light weight. The upper end of the seat tube frame body 10 is a mounting seat 11, and mounting holes 101 for mounting the clamping seat of the seat cushion are transversely penetrated through the left side surface and the right side surface of the mounting seat 11. In this embodiment, the lower end of the seat tube frame body 10 is a hollow structure, which further reduces the weight, and the seat tube frame body 10 is flat.
The rear end of the mounting seat 11 has two left and right upper locking projections 12 and two left and right lower locking projections 13, and a deformation groove 102 communicating with the mounting hole 101 is formed between each lower locking projection 13 and the corresponding upper locking projection 12. An upper passage 103 communicating the deformation groove 102 and the mounting hole 101 is formed between the two upper locking protrusions 12, a lower passage 104 communicating the deformation groove 102 and the mounting hole 101 is formed between the two lower locking protrusions 13, and the lower passage 104 and the upper passage 103 are in facing communication with each other.
