Problems solved by technology
In the prior art, the connection of copper pipes is generally to directly weld the pipes. Since the welding is a linear connection and the connection surface is small, cracks are prone to appear under the long-term internal pressure of the pipes, especially thin-walled copper pipes. Due to the small wall thickness of the thin-walled copper pipe, there are few contact surfaces of the pipe during welding, and the firmness of the connection is very weak, which has certain potential safety hazards.

Embodiment Construction
[0014] Below, the technical solution of the present invention will be described in detail through specific examples.
[0015] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of a thin-walled copper pipe connection structure proposed by the present invention.
[0016] refer to figure 1 , a connection structure for thin-walled copper pipes proposed by an embodiment of the present invention, comprising: a main pipe 1 and a sub-pipe 2, wherein both ends of the main pipe 1 are provided with first connecting parts 11, and the first connecting parts 11 at both ends of the main pipe 1 The connecting part 11 is arranged symmetrically along the axial center line of the main pipe 1, and the first connecting part 11 is formed by the pipe wall of the main pipe 1 protruding outward, since the first connecting part 11 is formed by the pipe wall of the main pipe 1 toward the outside. The outer protrusion is formed, therefore, the inside of the first connection part...

The invention discloses a thin-wall copper pipe connection structure which comprises a primary pipe and a secondary pipe. The two ends of the primary pipe are each provided with a first connection part, each first connection part is formed due to the fact that the pipe wall of the primary pipe protrudes outwards, and a pressing ring is arranged in a cavity of each first connection part; the outer diameter of the secondary pipe is smaller than the inner diameter of the primary pipe, the two ends of the secondary pipe are each provided with a second connection part, and each secondary connection part is formed due to the fact that the pipe wall of the secondary pipe is concave inwards. In the assembly process, the secondary pipe is located in the primary pipe, and the second connection parts correspond to the first connection parts. The aim of connecting thin-wall copper pipes is achieved through cooperation of the primary pipe and the secondary pipe, the structure is simple, connection firmness is high, and good sealing performance is achieved.
Description
technical field [0001] The invention relates to the technical field of copper processing, in particular to a thin-walled copper pipe connection structure. Background technique [0002] Copper pipe connectors are used as connection accessories in the installation of copper pipes, and their connection structure plays a decisive role in the firmness and safety of the pipeline. In the prior art, the connection of copper pipes is generally to directly weld the pipes. Since the welding is a linear connection and the connection surface is small, cracks are prone to appear under the long-term internal pressure of the pipes, especially thin-walled copper pipes. Because the wall thickness of the thin-walled copper pipe is small, there are few contact surfaces of the pipes during welding, and the firmness of the connection is very weak, which has certain potential safety hazards. Contents of the invention [0003] Based on the technical problems in the above-mentioned background tec...
