Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering, and in particular to a connection structure for irregularly shaped pipe fittings. Background Technology

[0002] Irregular pipe fittings refer to pipes with cross-sectional shapes that differ from traditional standard pipe fittings. Their cross-sections have asymmetrical, irregular, or special geometric structures. These pipe fittings meet the functional requirements of specific scenarios (such as fluid optimization, structural reinforcement, and spatial adaptation) through special design, but their complex shapes also bring technical challenges in processing, connection, and application.

[0003] Because of their irregular cross-sections, irregularly shaped pipe fittings are inconvenient to install in traditional processes, which affects installation efficiency. When the length of the irregularly shaped pipe needs to be adjusted, the entire irregularly shaped pipe needs to be disassembled and reinstalled with a new irregularly shaped pipe fitting, resulting in a waste of labor time and materials.

[0004] To address these issues, we provide a connection structure for irregularly shaped pipe fittings. Utility Model Content

[0005] The purpose of this utility model is to provide a connection structure for irregularly shaped pipe fittings, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a connection structure for an irregularly shaped pipe fitting, comprising a first clamping semicircle and a second clamping semicircle. The outer side of the top of the first clamping semicircle is uniformly provided with first fixing holes. One end of the upper surface of the first clamping semicircle is provided with a first fixing threaded hole, and the other end of the upper surface of the first clamping semicircle is provided with two first clamping holes. Several connecting rods are inserted through the inner side of the first fixing holes. The outer diameter of the connecting rods matches the inner diameter of the first fixing holes. A groove is formed on the surface of the connecting rod, and a clamping plate is slotted at one end of the groove. Two fixing holes are provided on the upper surface of the clamping plate, and a first connecting valve is inserted through each fixing hole. The first connecting valve passes through the fixing hole and connects to the first fixing threaded hole. The outer diameter of the first connecting valve matches the inner diameter of the fixing hole and the first fixing threaded hole. A second clamping semicircle is provided at one end of the first clamping semicircle. A second fixing hole is evenly provided on the outer side of the top of the second clamping semicircle. A second fixing threaded hole is provided at one end of the upper surface of the second clamping semicircle. Two second clamping holes are provided at the other end of the upper surface of the second clamping semicircle. A second connecting valve passes through the fixing hole provided on the upper surface of the clamping plate at the second clamping semicircle. Anti-slip pads are provided on the inner sides of the first and second clamping semicircles. Two connecting threaded rods pass through the inner sides of the first and second clamping holes.

[0007] Preferably, the anti-slip mat has a first shaped tube and a second shaped tube located on one side thereon, and the outer surfaces of the first and second shaped tubes are in contact with the inner side of the anti-slip mat.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] By using a clamping semicircle, when a component is damaged, it can be disassembled, replaced, or repaired individually without damaging the overall structure, significantly reducing maintenance difficulty and time costs. The connecting rod makes the connection more secure, and the snap-fit ​​design of the plate and groove allows for adjustment of the length of irregular tubes without overall disassembly. Compared with traditional welding or one-piece molding structures, installation efficiency is increased by more than 50%, and material waste is reduced by 30%. Attached Figure Description

A number of connecting rods 14 are inserted through the inner side of the first fixing hole 11. The outer diameter of the connecting rods 14 matches the inner diameter of the first fixing hole 11. The connecting rods 14 can be used for subsequent clamping adjustment of the first clamping semicircle 1 and the second clamping semicircle 2. The surface of the connecting rods 14 is provided with a groove 15. One end of the groove 15 is connected to a clamping plate 16. Through the cooperation of the groove 15 and the clamping plate 16, the first clamping semicircle 1 and the second clamping semicircle 2 can be fixed. The upper surface of the clamping plate 16 is provided with two fixing holes 17. A first connecting valve 18 is inserted through the fixing hole 17. The first connecting valve 18 passes through the fixing hole 17. The hole 17 is connected to the first fixing threaded hole 12. The outer diameter of the first connecting valve 18 matches the inner diameter of the fixing hole 17 and the first fixing threaded hole 12. Through the setting of the first connecting valve 18, the clamping plate 16 can be fixed, thereby preventing the clamping plate 16 from falling out of position. One end of the first clamping semicircle 1 is provided with a second clamping semicircle 2. The outer side of the top of the second clamping semicircle 2 is evenly provided with second fixing holes 21. Through the setting of the second fixing holes 21, the second clamping semicircle 2 can be clamped with the connecting rod 14. One end of the upper surface of the second clamping semicircle 2 is provided with a second fixing threaded hole 22. The hole 22 is provided to cooperate with the second connecting valve 24 to fix the position of the clamping plate 16. Two second clamping holes 23 are provided at the other end of the upper surface of the second clamping semicircle 2. The second clamping holes 23 are provided to cooperate with the connecting threaded rod 26 and the first clamping hole 13 to fix the first clamping semicircle 1 and the second clamping semicircle 2. The second connecting valve 24 is inserted into the fixing hole 17 provided on the upper surface of the clamping plate 16 at the second clamping semicircle 2. The anti-slip pad 25 is provided on the inner side of the first clamping semicircle 1 and the second clamping semicircle 2. Two connecting threaded rods 26 are inserted into the inner side of the first clamping hole 13 and the second clamping hole 23.

[0016] Working principle: In use, firstly, align one end of the first shaped tube 3 and the second shaped tube 4, and then wrap the anti-slip pad 25 around its surface. Secondly, insert the first clamping semicircle 1 and the second clamping semicircle 2 into the outside of the anti-slip pad 25 and clamp them. Pass the connecting rod 14 through the first fixing hole 11, and insert the clamping plate 16 into the groove 15 on the outside of the connecting rod 14. Pass the first connecting valve 18 through the fixing hole 17 and thread it into the first fixing threaded hole 12. Pass the second connecting valve 24 through the fixing hole 17 at the second clamping semicircle 2 and thread it into the second fixing threaded hole 12. The third step involves threading the threaded rod 26 through the first clamping hole 13 and then threading it to the second clamping hole 23. If reinforcement is required, the first clamping semicircle 1 can be welded to the first shaped tube 3, and the second clamping semicircle 2 can be welded to the second shaped tube 4. If extension or shortening is required, simply disassemble the threaded rod 26, the first connecting valve 18, and the second connecting valve 24, then remove the clamping plate 16, and remove the connecting rod 14 to remove the second shaped tube 4. This completes the process of using a connection structure for a shaped tube fitting.
