[0002] Tents are common camping equipment in daily life, and existing tents are all foldable; generally, tents include canvas, and a frame is often inserted into the canvas so that the tent can be supported on the ground. Generally, the frame is composed of hollow round tubes spliced ​​together, and the lengths of hollow round tubes required for supporting frames in different positions are different. At present, hollow round tubes are generally socketed together and then locked by elastic buckles; sometimes multiple hollow round tubes are connected through three-way interfaces or two-way interfaces; when the hollow round tubes are disassembled from each other, hollow round tubes of different lengths will be mixed together, which is inconvenient for the next assembly. When the tent is reassembled next time, it often takes time to find hollow round tubes of corresponding lengths to splice each other, and the user experience is poor. Therefore, it is necessary to design a connection device for multiple splicing pipes to overcome the above difficulties. Summary of the invention

The utility model respectively arranges a steel wire rope and an elastic rubber ring between two pipes to be spliced. The ends of the steel wire rope and the elastic rubber ring are installed in the pipes through elastic torsion springs. In this way, after the two pipes are split, they are still connected together through the steel wire rope and the elastic rubber rope body, which is convenient for re-splicing.

[0016] By setting an elastic buckle, the first hollow pipe and the second hollow pipe can be conveniently spliced ​​with other new pipes; other new pipes are provided with holes for installing arc-shaped protrusions, so that the first hollow pipe and the second hollow pipe can be spliced ​​with other new pipes by limiting the arc-shaped protrusions; when the arc-shaped protrusions are pressed, the arc-shaped protrusions are deformed and disengaged from the holes on the corresponding pipes, so that the first hollow pipe and the second hollow pipe can be separated from the other new pipes.

[0018] The ends of the third pin and the fourth pin are both stuck on the inner wall of the first hollow pipe or the second hollow pipe, and the arc-shaped protrusion is stuck in the first through hole or the second through hole, so that the elastic buckle can be firmly installed in the first hollow pipe or the second hollow pipe. When the arc-shaped protrusion is pressed, the arc-shaped protrusion can be deformed relative to the first through hole or the second through hole, thereby realizing the locking and unlocking functions.

[0019] Preferably, when the first connecting ring and the second connecting ring are in a stretched state, the steel wire rope on the second connecting ring is exposed at the open end of the first hollow pipe; when the elastic rubber ring is in a stretched state, the steel wire rope on the second connecting ring is exposed at the open end of the second hollow pipe; the open end of the second hollow pipe is provided with a placement notch for placing the steel wire rope.

[0020] When the first hollow pipe and the second hollow pipe are sleeved and installed together, the first connecting ring is in the first hollow pipe, the second connecting ring is between the first hollow pipe and the second hollow pipe, and the elastic rubber ring is in the second hollow pipe, so that the steel wire rope and the elastic rubber rope body will not interfere with the first hollow pipe and the second hollow pipe. When the first hollow pipe and the second hollow pipe are separated from each other, only the second connecting ring is exposed at the open ends of the first hollow pipe and the second hollow pipe; after further stretching the elastic rubber ring, only the second connecting ring is exposed at the open ends of the first hollow pipe and the second hollow pipe, so that the elastic rubber ring will not be worn, and only the steel wire rope on the second connecting ring is worn, so the connection between the steel wire rope and the elastic rubber rope body is more stable and reliable, and the service life is longer.
