For example, steel scaffolding is usually connected by a combination of multiple steel pipes. In order to reduce the corrosion of steel structures, the surface of steel structures is usually galvanized.

[0003] Before connecting the galvanized steel pipes, it is usually necessary to open holes on the surface of the galvanized steel pipes to facilitate the subsequent connection of the galvanized steel pipes through bolts based on the openings to form the corresponding steel structure frame.

[0004] After the hole opening treatment, the galvanized layer at the opening of the galvanized steel pipe is damaged, which is very easy to rust and affect the subsequent use. Utility Model Content

[0008] An inner cylinder, wherein the inner cylinder is arranged inside the outer tube, and a fixing piece is connected between the middle of the inner cavity of the outer tube and the middle of the outer wall of the inner cylinder;

[0009] The clamping mechanism is arranged at the upper and lower sides between the inner cylinder and the outer tube, and the outer part of the inner cylinder and the inner part of the clamping mechanism form a galvanized steel structure clamping area, and a rubber gasket is arranged on the side of the clamping mechanism facing the inner cylinder.

[0010] Preferably, the outer tube body, inner cylinder and fixing piece are integrally formed of stainless steel.

[0011] Preferably, sealing support gaskets are provided on the upper and lower surfaces of the fixing member, and the sealing support gaskets are made of rubber material.

[0012] Preferably, two clamping mechanisms are provided on the upper side or the lower side, and the two clamping mechanisms are arranged at opposite positions of the outer tube body.

[0014] Preferably, the moving mechanism includes an adjusting screw threadedly connected to the side wall of the outer tube body, one end of the adjusting screw extends into the outer tube body, a movable seat is provided on the outer wall of the clamping plate, and one end of the adjusting screw extending into the outer tube body is rotatably connected to the movable seat.

[0015] Preferably, the cross-section of the inner cylinder is circular or square.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] It is supported on the outside and inside of the steel pipe structure by the outer pipe body and the inner column. There is no need to open holes on the surface of the galvanized steel pipe, which protects the galvanized steel pipe and reduces the chance of subsequent corrosion.
