Embodiment 1

[0018] Such as figure 2 Shown, the structure diagram of this embodiment.

[0019] A connecting piece for telescopic doors, which includes a connecting pipe 11 and a cap 12, the connecting pipe 11 is composed of a main body 13 and ends, wherein one end of the connecting pipe 11 is an end cap 14 integrated with the main body, and the other One terminal is a hollow terminal 15 composed of four end cards. There is a gap between the end cards. Each end card is provided with an arc-shaped boss 16. The cap 12 is formed by an arc-shaped protrusion 17 and a brim. 18, wherein the brim 18 is provided with a card edge 19, the arc-shaped protrusion 17 matches the hollow end 15, and the card edge 19 matches the arc-shaped boss 16. When assembling and matching, the arc-shaped protrusion 17 is inserted into the inner diameter of the hollow end 15 to support the end clip, and at the same time, the card edge 19 of the cap tightly clamps the arc-shaped boss 16, so that the connecting pipe and ...

Embodiment 2

[0021] Such as image 3 Shown, the structure diagram of this embodiment.

[0022] It is basically the same as Embodiment 1, wherein the main body 13 is provided with a step, which facilitates the assembly and use of different cross bars, and can also be used in combination with the sleeve.

Embodiment 3

[0024] Such as Figure 4 Shown, the structure diagram of this embodiment.

[0025] It is basically the same as Embodiment 1, wherein the end cap 14 integrated with the main body on the connecting pipe 11 is further simplified according to assembly requirements.
