[0033] Embodiment 1

[0034] Please refer to Figure 1 and Figure 2The first embodiment of the present invention is: a tubular track connection structure, used to connect a first tubular track 1 and a second tubular track 2, the outer diameter of the first tubular track 1 is equal to the outer diameter of the second tubular track 2. The tubular track connection structure includes a first connection shaft 3 installed on the first tubular track 1 and a second connection shaft 4 installed on the second tubular track 2, the first connection shaft 3 includes a main body 31 and a cone 32, the second connection shaft 4 is provided with a cone hole 41 matched with the cone 32, and a buffer ring 5 is provided at the connection between the main body 31 and the cone 32.

[0035] The conical plug-in structure used in this technical solution can self-align the center, resist bending loads in all directions, prevent the connection structure of the tubular track from breaking or detaching, and keep the connection structure of the tubular track sufficiently flexible, which can reduce the vibration of the tubular track system. The problem that the cylindrical plug-in structure is prone to track breakage and separation due to its rigidity is overcome.

[0036] Specifically, the main body 31 includes a first insertion portion 311 inserted into the first tubular track 1 and a connecting portion 312 connecting the first insertion portion 311 and the cone 32. The diameter of the first insertion portion 311 is equal to the inner diameter of the first tubular track 1, the diameter of the connecting portion 312 is equal to the outer diameter of the first tubular track 1, and the diameter of the large diameter end of the cone 32 is smaller than the diameter of the connecting portion 312.

[0039] In order to prevent the first connecting shaft 3 from accidentally disengaging from the first tubular track 1, the first inserting portion 311 has a first screw hole and a first tool hole 3111 arranged along its radial direction, the first screw hole is coaxial with and connected to the first tool hole 3111, a first screw 7 is arranged in the first screw hole, the first screw 7 abuts against the inner wall of the first tubular track 1, and a first through hole 11 communicating with the first tool hole 3111 is arranged on the first tubular track 1.
