Embodiment Construction

[0012] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0013] As shown in the figure, the present invention includes a front fork sleeve 3, a saddle sleeve 1, a central shaft sleeve 5 and a rear axle yoke 6, and the front fork sleeve and the saddle sleeve are connected by an upper beam 2, and the middle The shaft sleeve and the front fork sleeve are connected through the lower beam 4, and the saddle sleeve and the center shaft sleeve are connected through the vertical beam 8. One end of the rear axle fork is used to install the rear axle, and the other end is connected to the center axle. The casing is fixedly connected, and the upper beam, lower beam and vertical beam are all triangular prism tubular structures, among which the triangular prism near the upper beam and the lo...

Abstract

The invention relates to a bicycle frame, in particular to a bicycle frame stable in structure and small in a bicycle body. The bicycle frame comprises a front-fork socket, a saddle casing, a middle-axle casing and a rear-axle fork frame, the front-fork socket and the saddle casing are connected through a top bar, the middle-axle casing and the front-fork socket are connected through a bottom bar, the saddle casing and the middle-axle casing are connected through a vertical beam, and one end of the rear-axle fork frame is used for mounting of a rear axle while the other end is fixedly connected with the middle-axle casing. Strength of the bicycle body is effectively improved through a tri-prism tubular structure, a triangular prism close to top bar and bottom bar sides is of a tri-prism edge surface of the vertical beam, a triangular prism close to the rear-axle fork frame is a tri-prism edge of the vertical beam, a circular-arc concave surface is arranged on the middle lower side of the vertical beam, a wheel protrudes into the circular-arc concave surface, the length of the bicycle body is effectively shortened, and the bicycle body is lighter.

Description

technical field [0001] The invention relates to a bicycle frame, in particular to a bicycle frame with a stable structure and a short body. Background technique [0002] The vehicle frame of bicycle generally comprises the front fork sleeve that is used to install front fork in the prior art, is used to install the saddle bushing of saddle, is used to install the central shaft bushing of central shaft, front fork sleeve and saddle The sleeves are connected by the upper beam, the center shaft sleeve and the front fork sleeve are connected by the lower beam, and the saddle sleeve and the center shaft sleeve are connected by the vertical beam, and it is also used to install the rear wheel One end of the rear axle yoke is used to install the rear axle, and the other end is fixedly connected with the center shaft sleeve. [0003] But the common bicycle body in the prior art is longer, and all the body beams are cylindrical, the body is poorly impacted, and the structure is unsta...
