Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe technology, and in particular to a transition type stainless steel pipe. Background Technology

[0002] When connecting stainless steel pipes in different directions, it is difficult to ensure a tight fit when using adapter components. Furthermore, multiple fasteners are required during installation, resulting in low overall installation efficiency. While the durability of the connection point is relatively high, the existing structure still cannot guarantee a tight seal when connecting stainless steel pipes in different directions. This design incorporates a right-angle adapter structure, using fasteners at the ends for connection. However, the sealing of the connection point remains compromised during fastening, and the welded connection strength is relatively poor. For connection points with high strength and sealing requirements, the existing structure cannot meet the connection needs of future use. Utility Model Content

By setting an integrated combination structure at both ends of the transition pipe, one end is equipped with a welding mating groove.

The other side can achieve rapid fastening assembly through a stop mechanism. The overall installation efficiency is higher and the connection strength is higher. It can replace the existing multiple components for fastening connection. The assembly operation is more convenient during use, and the durability is stronger in the later use.

Detailed Implementation

[0021] like Figures 1 to 7As shown, a type of transition stainless steel pipe includes a right-angled stainless steel transition pipe body 1. The left side of the stainless steel transition pipe body 1 has an integrally formed first stabilizing stop seat 2, which serves as a reinforcement and stop structure for left-side fitting. This ensures higher structural strength at the left side. The left side of the first stabilizing stop seat 2 has an integrally formed conical first splicing fitting post 3, which is inserted into the structure during stainless steel pipe connection. The center of the left end face of the first splicing fitting post 3 has a cylindrical welding fitting sealing groove 4, and the center hole on the left side of the first splicing fitting post 3 has a welding transition fitting groove 5 that completely penetrates vertically. Corresponding positions of the fitted stainless steel pipe have welding fitting clearance grooves, ensuring that welding material can flow into the appropriate positions during welding. In use, the fitted stainless steel pipe can also be inserted into the welding sealing fitting groove 4 as needed, and welding can be performed from the outside of the welding fitting structure. The length of the welding transition groove 5 in the left-right direction is greater than the depth of the welding mating sealing groove 4 in the left-right direction. A second welding stabilizing groove 7 and a first welding stabilizing groove 6 with circular cross-sections are respectively provided at the inner and outer edges of the welding transition groove 5, ensuring better stability during welding. The welding mating position has a reliable anti-loosening effect after welding, resulting in a more reliable connection. Two symmetrically distributed second mounting stabilizing plates 8 are provided on the lower right side of the stainless steel adapter pipe body 1. The lower end of the second mounting stabilizing plate 8 has an arc-shaped structure. A cylindrical second mounting positioning post 9 is provided on the outer side of the second mounting stabilizing plate 8. This serves as the connection mating structure when splicing stainless steel pipe products at the other end. It ensures the combined stability of the connection position during mating. A second combined guide post 10 is provided on the outer end face of the second mounting stabilizing plate 8. During mating, it allows for precise and stable combination and connection through the limiting groove on the combined stainless steel pipe. The second combined guide post 10 has a semi-conical structure, resulting in better connection smoothness during mating. It adopts a brand-new structural design, with integrated combination structures set at both ends of the adapter pipe. One end is equipped with welding grooves, which are staggered in different positions and directions to ensure better overall tightness and stability during welding connection. The other side can achieve rapid fastening combination through the stop mechanism. The overall installation efficiency is higher and the connection strength is higher. It can replace the existing combination of multiple components for fastening connection. The combination operation is more convenient during use and the durability is stronger in the later use. It can meet the use requirements of application environments with high sealing and strength requirements.

[0022] Preferably, the right side of the first stable mating stop seat 2 is a spherical structure, which provides higher structural strength and better mating safety during mating.

[0023] Preferably, the length of the welding transition groove 5 in the left-right direction is greater than half the length of the first splicing mating column 3 in the left-right direction. This ensures that when welding is performed, the welding material can be more fully and extensively integrated with the mating position, resulting in higher overall connection strength at the welding position and greater safety during later use.

[0024] Preferably, the width of the right side of the welding transition groove 5 is greater than the width of the left side, so that the welding position on the outer side can form a leftward anti-loosening fit effect after welding, which further improves the connection firmness of the connection position.

[0025] Preferably, both the second welding stabilizing groove 7 and the first welding stabilizing groove 6 are conical structures, which result in higher flow efficiency of welding materials and higher welding efficiency during welding.

[0026] Preferably, the projections of the second combined guide posts 10 at the outer positions of the second mounting positioning post 9 in the front-rear direction are staggered left-right, such as... Figure 6 As shown, a second combined guide post 10 is provided on each of the second mounting and positioning posts 9 on both sides. Their relative positions are staggered, which can further improve the combination stability of the mating position and effectively improve the mating strength.

[0027] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
