Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe technology, specifically to a stainless steel pipe structure that is easy to combine and connect. Background Technology

[0002] Stainless steel pipe is a hollow cylindrical tube made of stainless steel as raw material and processed through specific processes such as hot rolling, cold rolling, welding or cold drawing. It is widely used in petrochemical, building decoration, machinery manufacturing, medical equipment, food processing, aerospace and other fields.

[0003] Traditionally, stainless steel pipes are connected using welding or sleeves. While welding provides a strong seal and stability, it makes disassembly difficult. Sleeve connection, using bolts to join two stainless steel pipes, offers greater stability and allows for disassembly and reinstallation, but it results in lower sealing and is unsuitable for applications such as water pipes, thus limiting its applicability. Utility Model Content

[0004] The purpose of this invention is to provide a stainless steel pipe structure that is easy to assemble and connect, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel pipe structure that is easy to combine and connect, comprising two stainless steel pipes, each of the two stainless steel pipes having an inner connecting ring fitted inside its facing end, a fixing ring plate being installed between the two inner connecting rings, and each of the two stainless steel pipes having an outer connecting ring fitted outside its facing end, with two positioning screws symmetrically arranged at the upper and lower ends of the outer wall of the outer connecting ring, the positioning screws being threadedly connected to the fixing ring plate.

[0006] Preferably, the diameter of the stainless steel pipe is larger than the diameter of the fixing ring plate.

[0007] Preferably, the outer wall of the fixing ring plate has two symmetrical positioning holes at its upper and lower ends, and the size and position of the positioning holes are adapted to the positioning screws.

[0008] Preferably, both ends of the stainless steel pipe are provided with multiple insertion holes at equal intervals around the circumference, and the inner walls of the left and right sides of the fixing plate are provided with multiple insertion rods at equal intervals around the circumference, and the size and position of the insertion rods are adapted to the insertion holes.

[0009] Preferably, a sealing gasket is installed on the surface of multiple plug rods on the same side, and the size of the sealing gasket is smaller than the size of the fixing ring plate.

[0010] Preferably, two limiting screws are symmetrically installed on the outer collar surface of the positioning screw, and the inner end of the limiting screw is in contact with the surface of the stainless steel pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This conveniently assembled stainless steel pipe structure, during installation, involves moving two stainless steel pipes through the insertion holes and insertion rods towards the two inner connecting rings until one end of the stainless steel pipe is tightly fitted with the sealing gasket. At this point, the outer connecting ring is placed on the surface of the two stainless steel pipes and moved to the position of the fixing ring plate. The positioning screws are then manually rotated towards the fixing ring plate until they are threaded into the positioning holes. Next, the four upper and lower limit screws are sequentially rotated inward through the screw holes until they are in tight contact with the surface of the stainless steel pipes. The combined use of the insertion rod and insertion holes, along with the sealing gasket, ensures a good seal at the connection point of the two stainless steel pipes. Simultaneously, the outer connecting ring, positioning screws, and limit screws fix the two stainless steel pipes to the positions of the fixing ring plate and inner connecting rings, thus providing both good sealing and stability at the connection point, and allowing for secondary disassembly and installation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figures 1 to 4 As shown, this embodiment of the stainless steel pipe structure facilitates combination and connection, including two stainless steel pipes 1. The two stainless steel pipes 1 can be any two stainless steel pipes with the same inner and outer diameters, and the length is not required. An inner connecting ring 7 is fitted inside the facing ends of the two stainless steel pipes 1. The outer diameter of the inner connecting ring 7 is adapted to the inner diameter of the stainless steel pipe 1, allowing the stainless steel pipe 1 to fit over the inner connecting ring 7. A fixing ring plate 6 is installed between the two inner connecting rings 7, and the fixing ring plate 6 is fixedly connected to the two inner connecting rings 7, forming a passage for liquid flow. An outer connecting ring 2 is fitted outside the facing ends of the two stainless steel pipes 1. The inner diameter of the outer connecting ring 2 is adapted to the outer diameter of the stainless steel pipe 1, allowing the outer connecting ring 2 to fit over the two stainless steel pipes 1. Two positioning screws 3 are symmetrically arranged at the upper and lower ends of the outer wall of the outer connecting ring 2. The positioning screws 3 are threadedly connected to the fixing ring plate 6, connecting the outer connecting ring 2 and the fixing ring plate 6 through the positioning screws 3, forming a stable positional relationship.

[0021] Specifically, the diameter of the stainless steel pipe 1 is larger than the diameter of the fixed ring plate 6, such as... Figure 4 As shown, a groove is formed between the two stainless steel pipes 1 and the fixed ring plate 6. When the positioning screw 3 passes through the outer collar 2 and is threadedly connected to the fixed ring plate 6, the outer collar 2 will come into contact with the two stainless steel pipes 1, and the movement of the stainless steel pipes 1 will be limited by friction.

[0022] Furthermore, two positioning holes 10 are symmetrically opened at the upper and lower ends of the outer wall of the fixed ring plate 6. The size and position of the positioning holes 10 are adapted to the positioning screws 3. By using the positioning holes 10 and the positioning screws 3 together, the connection position between the outer collar 2 and the fixed ring plate 6 can be positioned.

[0023] Furthermore, both ends of the stainless steel pipe 1 are provided with multiple insertion holes 5 at equal intervals around the circumference, and multiple insertion rods 8 are installed at equal intervals around the circumference on the inner walls of the left and right sides of the fixing plate. The size and position of the insertion rods 8 are adapted to the insertion holes 5. By using the insertion holes 5 and the insertion rods 8 together, the connection strength between the stainless steel pipe 1 and the fixing ring plate 6 and the inner connecting ring 7 can be enhanced.

[0024] Furthermore, a sealing gasket 9 is installed on the surface of multiple plug-in rods 8 on the same side. The size of the sealing gasket 9 is smaller than that of the fixing ring plate 6, and the sealing gasket 9 provides a stable sealing effect.

[0025] Furthermore, two limiting screws 4 are symmetrically installed on the surface of the outer collar 2 of the positioning screw 3. The inner end of the limiting screw 4 is in contact with the surface of the stainless steel pipe 1. The limiting screw 4 can effectively limit the position of the stainless steel pipe 1 by applying strong pressure.

[0026] The method of use in this embodiment is as follows: During installation, two stainless steel pipes 1 are moved towards the two inner connecting rings 7 through the insertion holes 5 and the insertion rod 8 until one end of the stainless steel pipe 1 is tightly fitted with the sealing gasket 9. At this time, the outer connecting ring 2 is placed on the surface of the two stainless steel pipes 1 and moved to the position of the fixing ring plate 6. The positioning screw 3 is rotated manually towards the fixing ring plate 6 until the positioning screw 3 is threaded into the positioning hole 10. Then, the four upper and lower limit screws 4 are rotated inward through the screw holes until the limit screws 4 are in close contact with the surface of the stainless steel pipe 1. Through the cooperation of the insertion rod 8 and the insertion hole 5, and the sealing gasket 9, the connection of the two stainless steel pipes 1 has a good sealing effect. At the same time, with the help of the outer connecting ring 2, the positioning screw 3 and the limit screw 4, the positions of the two stainless steel pipes 1 with the fixing ring plate 6 and the inner connecting ring 7 are fixed, so that the connection has good sealing performance and stability, and can be disassembled and installed again.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
