[0009] Preferably, one end of the first joint side pipe and the second joint side pipe are respectively communicated with the vertical joint pipe, and one side of the first joint side pipe is communicated with one side of the second joint side pipe.

[0010] Preferably, a first connecting ring is provided at one end of the first joint side pipe away from the vertical joint pipe, and the diameter of the first connecting ring is smaller than the diameter of the first joint side pipe;

[0011] A second connecting ring is provided at one end of the second joint side pipe away from the vertical joint pipe, and a diameter of the second connecting ring is smaller than a diameter of the second joint side pipe.

[0012] Preferably, the diameter of the first joint-side pipe is smaller than the diameter of the second joint-side pipe.

[0013] Preferably, the diameter of the second joint side pipe is smaller than or equal to the diameter of the vertical joint pipe.

[0014] The beneficial effects of the utility model are as follows:

[0015] The joint side pipe is integrally formed after being bent by the vertical joint pipe, eliminating the need for the joint side pipe to be welded between the vertical joint pipes, thereby improving the structural strength of the bicycle frame joint. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0024] Example: Refer to Figure 1-Figure 3 As shown, a bicycle frame joint, the joint comprises:

[0025] A vertical joint pipe, a first joint side pipe and a second joint side pipe, wherein the first joint side pipe and the second joint side pipe are both arranged on one side of the vertical joint pipe, the first joint side pipe and the second joint side pipe are integrally formed by bending the vertical joint pipe, and the connection between the first joint side pipe and the second joint side pipe is welded.

[0026] The joint side pipe is integrally formed after being bent by the vertical joint pipe, eliminating the need for the joint side pipe to be welded between the vertical joint pipes, thereby improving the structural strength of the bicycle frame joint.

[0027] Furthermore, the joint also includes a first bearing base and a second bearing base. The first bearing base is embedded in the upper part of the vertical joint tube, and the second bearing base is embedded in the lower part of the vertical joint tube.
