Problems solved by technology
[0004] The light-duty pipe wall is very thin, and conventional processes such as tapping, clamping and welding are used for the thin pipe wall, which may easily lead to deformation or even damage of the pipe wall, making it impossible to connect normally
[0005] At the same time, the stiffening part inside the light pipe participates in the force of the light pipe and transmits a large amount of bending moment, shear force and torque. Therefore, when the light pipe is butted, the stiffening part must also be fully connected. Except for welding, all other conventional butt joint methods cannot be completed. Full butt joint of the stiffening part; while the light pipe cannot be disassembled after welding, which is inconvenient for storage and transportation

Embodiment Construction
[0023] The technical solutions of the present invention will be described in detail below according to the implementation manners given in the accompanying drawings.
[0024] The first, according to figure 2 and Figure 8 As shown, for the butt joint of light pipe 21 and light pipe 22 of the same outer diameter. First screw one end of the inner tube connecting screw 5 into the tapped inner tube 2 in the light pipe 21, then insert the inner tube connecting screw 5 into the central circular hole 7 of the docking ring 4, and then connect the inner tube connecting screw 5 The other end is screwed into the tapping inner circular tube 2 in another lightweight tube 22. Tighten the thread until the two light-duty pipes snap into the annular groove in the docking ring 4 and fully contact with the pressure transmission gasket 9, that is, two light-duty pipes are butted.
[0025] The second, according to figure 2 and Figure 9 As shown, the butt joint of light pipes 23 and light p...

The invention provides butt-joint rings of concentric inner tube light metal tubes and a butt-joint structure with the butt-joint rings. The butt-joint structure comprises a light tube and another light tube which are composed of concentric outer tubes and inner tubes, have the same outer diameter, and are connected through the butt-joint rings and inner tube connection screws. Concentric outer tubes and the inner tubes of the light tubes are evenly connected through three sheet-shaped structures, and the cross section circles of the light tubes are divided into three parts. Tapped threads are arranged at two ends of the inner tubes. Each butt-joint ring is of a round ring structure with a gasket in the middle, the periphery of the butt-joint ring is a tube wall protection ring, the inner diameter of the tube wall protection ring is identical to the outer diameter of each outer tube, a pressure transfer gasket evenly divides the tube wall protection ring into two parts, the center of the pressure transfer gasket is a circular hole, and the diameter of the circular hole is identical to that of each inner tube of the light tubes. By means of the butt-joint rings of the concentric inner tube light metal tubes and the butt-joint structure with the butt-joint rings, the light tubes are not easy to break, capable of being disassembled and convenient to transport and carry. Besides, butt joint of the light tubes with any tube diameters can be achieved.
Description
technical field [0001] The invention relates to a butt joint ring with a concentric inner tube light pipe and a butt joint structure utilizing the butt joint ring. Background technique [0002] The light pipe in the present invention is a tubular structure made of lighter material with thinner wall and internal reinforcement. [0003] At present, the butt joint methods between light pipes include thread tightening, welding, bonding, flange butt joint and bearing butt joint. [0004] The light-duty pipe wall is very thin, and conventional processes such as tapping, clamping and welding are used for very thin pipe walls, which may easily lead to deformation or even damage of the pipe wall, making it impossible to connect normally. [0005] At the same time, the stiffening part inside the light pipe participates in the force of the light pipe and transmits a large amount of bending moment, shear force and torque. Therefore, when the light pipe is butted, the stiffening part mu...
