A pipe connection structure

Technical field

The utility model belongs to the field of pipeline connection structures, and particularly relates to a pipeline connection structure.

Background technique

At present, the structural design of traditional HVAC pipes is relatively simple. Generally, the connection methods of steel pipes used for outdoor transportation include welding and flange connection. The pipes are troublesome to operate during installation, disassembly, maintenance and replacement, and reduce work efficiency. The labor intensity of workers is high. Indoor HVAC pipes generally include PERT pipes, aluminum-plastic pipes, PB pipes, and PEX pipes. The connection methods include hot melt and threaded connections. There are also troubles in the installation, disassembly, maintenance and replacement of pipes. Although there are currently clamps to connect pipelines, it also meets the requirements of relatively convenient installation and disassembly of pipelines. For example, a quick-opening pipeline connection device proposed in the Chinese utility model patent document No. CN203628106U can realize Tightening and disassembly of pipe joints, but in this way, it is necessary to align the pipe connection ends, then put clamp A and clamp B on the pipe joint, and then tighten the nut, because the connection device is If it exists alone, the efficiency of its connecting device itself on the pipeline still needs to be improved.

Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model more clear, the utility model will be further described in detail below with reference to the drawings and embodiments.

As shown in Figure 1-Figure 6. A pipe connection structure includes a first pipe body 1 and a second pipe body 2 butted to each other. The end of the first pipe body 1 is a convex conical plug 4. The end of the plug 4 is located on the outer wall of the first pipe body 1. A pipe clamp 3 is provided. The end of the second pipe body 2 opposite to the convex cone is provided with a concave conical jack 5. On the outer wall of the second pipe body 2, a pipe clamp 2 6 is located at the end where the jack 5 is located. The plug 4 is located in the jack. 5, the outer wall of the plug 4 is in contact with the inner wall of the jack 5, a sealing ring 7 is set between the end of the plug 4 and the inner end face of the jack 5, and the pipe clamp one 3 and the pipe clamp two 6 are connected through a locking structure and locked The structure includes that at least two latch ears 8 are symmetrically arranged on the pipe clamp one 3, the latch ear two 9 corresponding to the latch ear 8 is arranged on the pipe clamp two 6, the pin hole one 10 is provided on the latch ear 8, and the latch ear two 9 is provided with pin hole two 11, and pin hole one 10 and pin hole two 11 are provided with a latch 12.

When in use, insert the plug 4 of the first pipe body 1 into the socket 5 of the second pipe body 2 until the plug 4 presses the sealing ring 7, insert the plug pin 12 into the pin hole one 10 and the pin hole two 11 to achieve fixation, and disassemble Just remove the pin 12. The tapers of the plug 4 and the jack 5 are consistent. There is a margin between the end of the plug 4 and the bottom of the jack 5. After the plug 4 is inserted into the jack 5, the tapers of the two are in contact with each other.

Through the convex tapered plug 4 at the end of the first tube body 1, the second tube body 2 is provided with a concave tapered socket 5. The plug 4 is located inside the socket 5, and the outer wall of the plug 4 and the inner wall of the socket 5 are are in contact with each other, and a sealing ring 7 is provided between the end of the plug 4 and the inner end surface of the jack 5. The sealing ring 7 can ensure the sealing of the pipeline connection. After the pipe clamp 1 3 and the pipe clamp 2 6 are connected through the locking structure, they can be The first pipe body 1 and the second pipe body 2 are connected.
