[0011] This type of assembled stainless steel pipe achieves a quick and tight connection between pipes by designing structures such as positioning protrusions, limit pipes, connecting grooves, positioning grooves, springs and positioning baffles, thereby reducing installation time and improving work efficiency. At the same time, it ensures the tightness of the connection, effectively prevents corrosion, looseness and leakage at the interface, and reduces the construction period and installation cost.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] See also Figure 1-Figure 5, an assembled stainless steel pipe, comprising a stainless steel pipe body 1 and a connecting pipe 3, characterized in that positioning protrusions 6 are fixedly installed at both ends of the stainless steel pipe body 1, and the positioning protrusions 6 are used to accurately position the connecting pipe 3. A limiting tube 9 is fixedly installed inside the stainless steel pipe body 1, and connecting grooves 10 are provided at both ends of the connecting pipe 3, and are slidably connected to the stainless steel pipe body 1. Positioning grooves 5 are provided at both ends of the connecting pipe 3, and are connected to the connecting grooves 10. Connecting grooves 10 are provided at both ends of the connecting pipe 3, so that the connecting pipe 3 can be slidably connected to the stainless steel pipe body 1. At the same time, positioning grooves 5 are also provided at both ends of the connecting pipe 3, and the positioning grooves 5 and the connecting grooves 10 are connected. The spring 7 and the positioning baffle 8 are used in combination. When the connecting pipe 3 is connected to the stainless steel pipe body 1, the positioning baffle 8 is squeezed by the stainless steel pipe body 1 and compresses the spring 7, thereby ensuring that the connecting pipe 3 can smoothly enter the connecting groove 10 and be tightly connected to the stainless steel pipe body 1. Hoops 2 are provided at both ends of the connecting pipe 3, and the stainless steel pipe body 1 and the connecting pipe 3 are firmly connected together by fasteners (such as bolts, nuts, etc.), ensuring that the connection of the entire stainless steel pipe body 1 is more stable and safe.

[0020] When in use, align the two ends of the connecting tube 3 with the two ends of the stainless steel tube body 1, and slowly push the stainless steel tube body 1 into the connecting tube 3, so that the positioning protrusion 6 smoothly enters the positioning groove 5, thereby realizing the precise positioning of the connecting tube 3 and the stainless steel tube body 1, and ensuring the stability and reliability of the connection. When the stainless steel tube body 1 is completely pushed into the connecting tube 3, the positioning baffle 8 will be squeezed by the stainless steel tube body 1 and compress the spring 7, and a certain resistance can be felt at this time. At this time, the stainless steel tube body 1 is rotated to enter the other end of the positioning groove 5, and the stainless steel tube body 1 is loosened. Due to the force of the spring 7, the connection between the stainless steel tube body 1 and the connecting tube 3 is realized. The utility model can realize quick and tight connection, thereby reducing installation time and improving work efficiency. At the same time, the spring 7 and the positioning baffle 8 in the connecting groove 10 are used in combination to provide a certain buffering and shock absorption effect during the connection process, effectively reducing the vibration and noise of the pipeline system. The utility model uses a sliding connection method, and the connection can be achieved by simply pushing the stainless steel pipe body 1 into the connecting pipe 3. No complicated installation steps and tools are required, which greatly improves the installation efficiency. Hoops 2 are respectively set at both ends of the connecting pipe 3, and the hoop 2 is tightly connected to the connecting pipe 3 and the stainless steel pipe body 1 through fasteners to ensure the stability and safety of the entire assembled stainless steel pipe.

[0021] like Figure 2 or Figure 5As shown, the positioning groove 5 is provided outside the connection groove 10 and is consistent in size with the positioning protrusion 6. The positioning groove 5 is in the shape of a barb. In the above-mentioned use process, the precise matching of the positioning protrusion 6 and the positioning groove 5 simplifies the installation steps and improves the installation efficiency. The installation can be easily completed without complicated tools or skills. The barb-shaped design of the positioning groove 5 ensures that the positioning protrusion 6 can be firmly locked after insertion, effectively preventing the connection pipe 3 from sliding or falling off, and improving the stability and reliability of the connection.

[0022] like Figure 2 or Figure 5 As shown, sealing rubber rings 4 are fixedly installed on the outer sides of the connecting pipes 3 on both sides of the connecting groove 10. In the above-mentioned use process, the sealing performance of the pipeline connection is effectively improved by installing the sealing rubber rings 4 on both sides of the connecting pipe 3. The sealing rubber ring 4 can fit tightly to the surface of the stainless steel pipe body 1 to prevent liquid or gas from leaking from the connection, thereby ensuring the safe operation of the pipeline system.

[0023] like Figure 1 or Figure 5 As shown, the shape and size of the connecting groove 10 match the stainless steel pipe body 1. During the above-mentioned use, the stainless steel pipe body 1 can be smoothly and tightly inserted into the connecting pipe 3, thereby achieving a better connection effect, improving the stability and safety of the pipeline system, and reducing leakage problems caused by loose connections.

[0024] like Figure 3 As shown, the inner wall of the connecting pipe 3 and the connecting groove 10 are coated with a special corrosion-resistant coating. During the above-mentioned use process, the special corrosion-resistant coating can effectively resist various corrosive substances, such as acid, alkali, salt, etc., thereby significantly extending the service life of the assembled stainless steel pipe. Due to the protective effect of the corrosion-resistant coating, the rust and damage of the pipeline are reduced, thereby reducing the frequency of maintenance and replacement, and saving maintenance costs.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
