Abstract

The utility model discloses an arched bicycle frame belonging to the field of bicycles. The arched bicycle frame comprises a middle pipe used for mounting a saddle, a head pipe, a lower pipe, a lower fork, an upper fork and an upper pipe, wherein the lower ends of the lower pipe and the lower fork are connected with the middle pipe through a five-way joint; the upper end of the lower pipe is connected with the head pipe, the upper pipe is bent upwards; the front end of the upper pipe is connected to the head pipe; the tail end of the upper pipe is connected to the middle pipe; the upper fork is bent upwards; the front end of the upper fork is connected to the left side and the right side of the upper pipe and the middle pipe; the tail end of the upper fork is connected with the tail end of the lower fork through a hook; and the upper pipe and the upper fork are connected to form a streamline arc shape from the head pipe to the hook. The arched bicycle frame has the beneficial effect that a bicycle frame just like a bow of a bow-and-arrow is formed by skillful connection of the upper pipe and the upper fork; the arched bicycle frame is compact in appearance, strong in streamline feel and comfortable to ride.

Description

Arc cycle frame

Technical field

The utility model relates to a kind of arc cycle frame, belongs to the bicycle field.

Background technology

Common old-fashioned bicycle all is comprised of front triangle and Vee formation two large divisions usually, forms a fitfull quadrangle, and such structure is the simple and crude high-strength impact requirement that can not meet present mountain bike both.

Summary of the invention

For addressing the above problem, the utility model provides a kind of arc cycle frame.

The utility model is realized with following technical scheme: a kind of arc cycle frame comprises for the pipe of vehicle seat is installed head tube, lower pipe, lower fork, upper fork and upper pipe; The lower end of lower pipe and lower fork is connected with middle pipe by five-way; The upper end of lower pipe is connected with head tube, described upper pipe K/UP, and front end is connected on head tube, and tail end is connected on middle pipe; Upper fork K/UP, front end is connected in the left and right sides of pipe and middle pipe, and tail end is connected with the tail end of lower fork by hooking pawl; Upper pipe and upper fork connect to form one from head tube to the streamline arc that hooks pawl.

The beneficial effects of the utility model are: by the ingenious linking of upper pipe and upper fork, form a vehicle frame as the bow of bow and arrow; Outward appearance is succinct, the streamline sense is superpower; Comfortable riding.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is upper fork structural representation.

In figure: 1, head tube; 2, lower pipe; 3, five-way; 4, lower fork; 5, hook pawl, 6, upper fork, 7, middle pipe; 8, upper pipe.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

As depicted in figs. 1 and 2, a kind of arc cycle frame, comprise the pipe 7 for vehicle seat is installed, head tube 1, lower pipe 2, lower fork 4, upper fork 6 and upper pipe 8; The lower end of lower pipe 2 and lower fork 4 is connected with middle pipe 7 by five-way 3; The upper end of lower pipe 2 is connected with head tube 1, upper pipe 8 K/UPs, and front end is connected on head tube 1, and tail end is connected on middle pipe 7; Upper fork 6 K/UPs, front end is connected in the left and right sides of pipe 8 and middle pipe 7, and tail end is connected with the tail end of lower fork 4 by hooking pawl 5; Upper pipe 8 and upper fork 6 connect to form one from head tube to the streamline arc that hooks pawl.Whole vehicle frame is as " bow " of bow and arrow.

Specific practice is: above manage the 8 rear front ends that bend and be welded on head tube, tail end is welded on middle pipe, and then upper fork is also by bending, and front end is welded in the left and right sides of pipe and middle pipe, and tail end is welded in and hooks on pawl.By the ingenious linking of upper pipe and upper fork, two pipe fittings with camber form one and become a streamline large arc smoothly from head tube to hooking claw type, as " bow " of bow and arrow, and the outward appearance simplicity generosity.
