[0001] The utility model relates to the technical field of stainless steel pipes, in particular to a composite stainless steel pipe for a water pump. Background Art

[0002] Stainless steel pipe is a tubular product made of stainless steel. Its excellent corrosion resistance, mechanical strength, and aesthetic appearance make it widely used in various fields. This pipe withstands long-term use in harsh environments without rusting, making it particularly suitable for industries such as the chemical, petroleum, pharmaceutical, food, construction, and decoration. Stainless steel pipe comes in a wide variety of types, including seamless and welded pipes, allowing you to choose the appropriate specifications and material based on your specific needs. Its smooth surface makes it easy to clean and maintain, and it is recyclable, meeting environmental standards.

[0003] Currently, when a water pump is working, an external stainless steel pipe is required. However, it is inconvenient to connect the existing stainless steel pipe to the water pump, which seriously affects the working efficiency of the water pump.

[0004] Therefore, a composite stainless steel pipe for a water pump is proposed. Utility Model Content

[0005] The utility model aims to provide a composite stainless steel pipe for a water pump.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A composite stainless steel pipe for a water pump, comprising:

[0008] The pump outlet and stainless steel pipe body conflict with each other;

[0009] The water pump outlet and the outer wall of the stainless steel pipe body are respectively provided with a first external thread and a second external thread;

[0010] A fixing ring is provided on the water pump outlet and the outer wall of the stainless steel pipe body, and an internal thread is provided on the inner wall of the fixing ring. The fixing ring is threadedly connected to the water pump outlet and the outer wall of the stainless steel pipe body through the internal thread, the first external thread and the second external thread;

[0011] The fixing ring is arranged at the contact point between the outlet end of the water pump and the main body of the stainless steel pipe.

[0012] Preferably, a connection groove is formed at one end of the water pump outlet close to the stainless steel pipe body, and a connection block located inside the connection groove is fixed at one end of the stainless steel pipe body close to the water pump outlet.

[0013] Preferably, the stainless steel pipe body is composed of a stainless steel pipe body, a protective layer, and a wear-resistant layer in sequence from the inside to the outside.

[0014] Preferably, the outer wall of the stainless steel tube body is connected with a connecting ring, and the connecting ring is composed of a first half ring and a second half ring;

[0015] A connecting column is fixed to the outer wall of the first semi-ring, a connecting strip is fixed to the outer wall of the connecting column, and a first limiting plate and a second limiting plate are fixed to the bottom of the connecting strip.

[0016] Preferably, the first limiting plate and the second limiting plate are respectively arranged on both sides of the fixing ring.

[0017] Preferably, the outer walls of the first half ring and the second half ring are respectively fixed with a first connecting ear and a second connecting ear, and the tops of the first connecting ear and the second connecting ear are respectively opened with a first connecting hole and a second connecting hole;

[0018] Threaded parts are provided in the first connecting hole and the second connecting hole;

[0019] A limiting plate is fixed to one end of the threaded member, and a limiting ring is threadedly connected to the outer wall of the threaded member;

[0020] The limiting plate abuts against the first connecting ear, and the limiting ring abuts against the second connecting ear.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The utility model is implemented by making the stainless steel pipe body contact with the water pump outlet, at which time the connecting block will be located inside the connecting groove, and then the fixing ring will be rotated, and the fixing ring will be moved to the contact point between the stainless steel pipe body and the water pump outlet through the internal thread cooperating with the first external thread and the second external thread, so that the connection and installation work of the stainless steel pipe body and the water pump outlet is completed. Compared with the existing ones, the utility model is convenient for connecting and installing the stainless steel pipe body and the water pump outlet, thereby improving the working efficiency of the water pump.

[0023] Since the stainless steel pipe body is composed of a stainless steel pipe body, a protective layer, and a wear-resistant layer from the inside to the outside, the protective layer can improve the structural strength of the stainless steel pipe body, and the wear-resistant layer can improve the wear resistance of the stainless steel pipe body. The two work together to greatly improve the structural strength and wear resistance of the stainless steel pipe body, thereby increasing the service life of the stainless steel pipe body.

[0024] The utility model places the first half ring and the second half ring on the outer wall of the stainless steel pipe body, then places the threaded part into the first connecting hole and the second connecting hole, and then passes the limiting ring. After one end of the limiting ring abuts the second connecting ear and one end of the limiting plate abuts the first connecting ear, the first half ring and the second half ring can be fixed to the outer wall of the stainless steel pipe body. Since the outer wall of the first half ring is fixed with a connecting column, the outer wall of the connecting column is fixed with a connecting strip, and the bottom of the connecting strip is fixed with the first limiting plate and the second limiting plate, the first limiting plate and the second limiting plate are respectively arranged on both sides of the fixing ring, so the fixing ring can be limited with the cooperation of the first limiting plate and the second limiting plate to prevent the fixing ring from loosening, thereby improving the stability of the connection between the stainless steel pipe body and the water pump outlet and preventing it from leaking.

[0032] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0033] Example 1:

[0034] See also Figure 1 、 3 -5. The present invention provides a technical solution: To achieve the above-mentioned purpose, the present invention provides the following technical solution: A composite stainless steel pipe for a water pump, comprising: a water pump outlet 1 and a stainless steel pipe main body 2 that conflict with each other; the outer walls of the water pump outlet 1 and the stainless steel pipe main body 2 are respectively provided with a first external thread 3 and a second external thread 4; a fixing ring 5 is provided on the outer wall of the water pump outlet 1 and the stainless steel pipe main body 2, and an internal thread 6 is provided on the inner wall of the fixing ring 5. The fixing ring 5 is threadedly connected to the outer wall of the water pump outlet 1 and the stainless steel pipe main body 2 through the internal thread 6 in conjunction with the first external thread 3 and the second external thread 4; the fixing ring 5 is provided at the conflicting position of the water pump outlet 1 and the stainless steel pipe main body 2, and a connecting groove 7 is provided at one end of the water pump outlet 1 close to the stainless steel pipe main body 2, and a connecting block 8 located inside the connecting groove 7 is fixed at one end of the stainless steel pipe main body 2 close to the water pump outlet 1, and the stainless steel pipe main body 2 is composed of a stainless steel pipe body 101, a protective layer 102, and a wear-resistant layer 103 from the inside to the outside.

[0035] Specifically, the utility model makes the stainless steel pipe main body 2 conflict with the water pump outlet 1. At this time, the connecting block 8 will be located inside the connecting groove 7. Then the fixing ring 5 is rotated. The fixing ring 5 will cooperate with the first external thread 3 and the second external thread 4 through the internal thread 6 to move to the conflict point between the stainless steel pipe main body 2 and the water pump outlet 1. At this point, the connection and installation work of the stainless steel pipe main body 2 and the water pump outlet 1 is completed. Compared with the existing ones, the utility model facilitates the connection and installation of the stainless steel pipe main body 2 and the water pump outlet 1, thereby improving the working efficiency of the water pump.

[0036] Since the stainless steel pipe main body 2 is composed of a stainless steel pipe body 101, a protective layer 102, and a wear-resistant layer 103 from the inside to the outside, the protective layer 102 can improve the structural strength of the stainless steel pipe main body 2, and the wear-resistant layer 103 can improve the wear resistance of the stainless steel pipe main body 2. The two work together to greatly improve the structural strength and wear resistance of the stainless steel pipe main body 2, thereby improving the service life of the stainless steel pipe main body 2.

[0037] Example 2:

[0038] See also Figure 1 、 2The utility model provides a technical solution: a composite stainless steel pipe for a water pump, the outer wall of the stainless steel pipe body 2 is connected to a connecting ring, the connecting ring is composed of a first half ring 9 and a second half ring 10; a connecting column 18 is fixed to the outer wall of the first half ring 9, and a connecting strip 19 is fixed to the outer wall of the connecting column 18, and a first limiting plate 20 and a second limiting plate 21 are fixed to the bottom of the connecting strip 19, and the first limiting plate 20 and the second limiting plate 21 are respectively arranged on both sides of the fixing ring 5, and the outer walls of the first half ring 9 and the second half ring 10 are respectively fixed with a first connecting ear 11 and a second connecting ear 12, and the tops of the first connecting ear 11 and the second connecting ear 12 are respectively opened with a first connecting hole 13 and a second connecting hole 14; a threaded member 15 is provided in the first connecting hole 13 and the second connecting hole 14; a limiting plate 16 is fixed to one end of the threaded member 15, and a limiting ring 17 is threadedly connected to the outer wall of the threaded member 15; the limiting plate 16 abuts against the first connecting ear 11, and the limiting ring 17 abuts against the second connecting ear 12.

[0039] Specifically, the utility model places the first half ring 9 and the second half ring 10 on the outer wall of the stainless steel pipe body 2, and then places the threaded member 15 into the first connecting hole 13 and the second connecting hole 14, and then passes through the limiting ring 17. After one end of the limiting ring 17 abuts against the second connecting ear 12 and one end of the limiting plate 16 abuts against the first connecting ear 11, the first half ring 9 and the second half ring 10 can be fixed to the outer wall of the stainless steel pipe body 2. Since the outer wall of the first half ring 9 is fixed with a connecting column 18, the outer wall of the connecting column 18 is fixed with a connecting strip 19, and the bottom of the connecting strip 19 is fixed with a first limiting plate 20 and a second limiting plate 21. The first limiting plate 20 and the second limiting plate 21 are respectively arranged on both sides of the fixing ring 5. Therefore, the fixing ring 5 can be limited under the cooperation of the first limiting plate 20 and the second limiting plate 21 to prevent the fixing ring 5 from loosening, thereby improving the stability of the connection between the stainless steel pipe body 2 and the water pump outlet 1 and preventing it from leaking.

[0040] Working principle:

[0041] First, the stainless steel pipe body 2 is brought into contact with the water pump outlet 1. At this time, the connecting block 8 will be located inside the connecting groove 7. Then, the fixing ring 5 is rotated. The fixing ring 5 will cooperate with the first external thread 3 and the second external thread 4 through the internal thread 6 to move to the contact point between the stainless steel pipe body 2 and the water pump outlet 1. At this point, the connection and installation work of the stainless steel pipe body 2 and the water pump outlet 1 is completed. Compared with the existing ones, the utility model facilitates the connection and installation of the stainless steel pipe body 2 and the water pump outlet 1, thereby improving the working efficiency of the water pump.

[0042] Secondly, since the stainless steel pipe main body 2 is composed of a stainless steel pipe body 101, a protective layer 102, and a wear-resistant layer 103 from the inside to the outside, the protective layer 102 can improve the structural strength of the stainless steel pipe main body 2, and the wear-resistant layer 103 can improve the wear resistance of the stainless steel pipe main body 2. The two work together to greatly improve the structural strength and wear resistance of the stainless steel pipe main body 2, thereby improving the service life of the stainless steel pipe main body 2.

[0043] Finally, by placing the first half ring 9 and the second half ring 10 on the outer wall of the stainless steel pipe body 2, and then placing the threaded member 15 into the first connecting hole 13 and the second connecting hole 14, and then passing the limiting ring 17, after one end of the limiting ring 17 abuts against the second connecting ear 12 and one end of the limiting plate 16 abuts against the first connecting ear 11, the first half ring 9 and the second half ring 10 can be fixed to the outer wall of the stainless steel pipe body 2. Since the outer wall of the first half ring 9 is fixed with a connecting column 18, the outer wall of the connecting column 18 is fixed with a connecting strip 19, and the bottom of the connecting strip 19 is fixed with a first limiting plate 20 and a second limiting plate 21, the first limiting plate 20 and the second limiting plate 21 are respectively arranged on both sides of the fixing ring 5, so the fixing ring 5 can be limited under the cooperation of the first limiting plate 20 and the second limiting plate 21 to prevent the fixing ring 5 from loosening, thereby improving the stability of the connection between the stainless steel pipe body 2 and the water pump outlet 1 and preventing it from leaking.
