Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, specifically to a PPH pipeline that is easy to connect. Background Technology

[0002] PPH pipes are made by β-modifying ordinary PP material, giving it a uniform and delicate Beta crystal structure. This results in excellent chemical corrosion resistance, wear resistance, good insulation, high temperature resistance (working temperature up to 100°C), non-toxicity, light weight, and ease of transportation and installation. It is a high-quality product that is more resistant to high temperatures, corrosion, and aging than PP pipes.

[0003] Currently, when installing PPH pipes, it is necessary to manually align the two PPH pipes and then connect them with bolts. However, during the alignment process, the two pipes are prone to deviation, which wastes the construction workers' time and is not convenient for installation and fixation. Utility Model Content

[0004] The purpose of this invention is to provide a PPH pipe that is easy to 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 PPH pipe that is easy to connect, comprising a first pipe and a second pipe. A first connecting plate is fixedly connected to one side of the first pipe. A guide groove is provided on one side of the first connecting plate. A first limiting groove is symmetrically arranged on the first connecting plate corresponding to the guide groove. A receiving groove is provided on both sides of the first limiting groove. A return spring is fixedly connected to the bottom of each receiving groove. A limiting ball is fixedly connected to one end of each return spring. A second connecting plate is fixedly connected to one end of the second pipe. A limiting block is symmetrically arranged on one side of the second connecting plate. A second limiting groove is provided on both sides of each limiting block. A sealing gasket is provided between the two limiting blocks.

[0006] Preferably, the first connecting plate and the second connecting plate are provided with arrayed connecting holes, and the connecting holes on the first connecting plate and the connecting holes on the second connecting plate are correspondingly provided.

[0007] Preferably, the guide groove is a ring structure design, and both first limiting grooves and limiting blocks are arc-shaped structures.

[0008] Preferably, the two limiting blocks are slidably connected to the guide groove, and the two limiting blocks are slidably connected to the two first limiting grooves.

[0009] Preferably, the second limiting groove is designed as a semi-circular structure, and the limiting ball is provided correspondingly to the second limiting groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are: through the structural design of the limiting block and the limiting ball, the two PPH pipes can be initially connected and fixed when they are connected, and then connected and fixed, avoiding the deviation that occurs during the connection of pipes with bolts, and facilitating the connection and fixation of pipes.

[0017] 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.

[0018] Please see Figure 1-5 This utility model provides a technical solution: a PPH pipe that is easy to connect, including a first pipe 1 and a second pipe 2. A first connecting plate 3 is fixedly connected to one side of the first pipe 1. A guide groove 4 is opened on one side of the first connecting plate 3. A first limiting groove 5 is symmetrically arranged on the first connecting plate 3 corresponding to the guide groove 4. A receiving groove 6 is opened on both sides of the first limiting groove 5. A return spring 7 is fixedly connected to the bottom of each receiving groove 6. A limiting ball 8 is fixedly connected to one end of each return spring 7. A second connecting plate 9 is fixedly connected to one end of the second pipe 2. A symmetrically arranged limiting block 10 is fixedly connected to one side of the second connecting plate 9. A second limiting groove 11 is opened on both sides of the limiting block 10. A sealing gasket 12 is provided between the two limiting blocks 10.

[0019] The first connecting plate 3 and the second connecting plate 9 are provided with connecting holes 13 arranged in an array. The connecting holes 13 of the first connecting plate 3 and the connecting holes 13 of the second connecting plate 9 are correspondingly set to facilitate the bolt connection between the first connecting plate 3 and the second connecting plate 9 through the connecting holes 13. The guide groove 4 is designed with a ring structure. The two first limiting grooves 5 and the limiting blocks 10 are all designed with an arc structure. The two limiting blocks 10 are slidably connected to the guide groove 4 and the two first limiting grooves 5, so that the limiting blocks 10 can slide into the first limiting grooves 5 within the guide groove 10. The second limiting grooves 11 are all designed with a semi-circular structure. The limiting ball 8 is correspondingly set to the second limiting groove 11, so that the limiting ball 8 can limit the second limiting groove 11.

[0020] Specifically, when using this utility model, the two limiting blocks 10 of the first connecting plate 3 are aligned and inserted into the guide groove 4 of the second connecting plate 9. The first connecting plate 3 is rotated, which in turn drives the limiting blocks 10 to correspond with the first limiting groove 5. The corresponding limiting blocks 10 are then inserted into the first limiting groove 5. At this time, the limiting ball 8 is squeezed by the limiting blocks 10. The squeezed limiting ball 8 moves into the receiving groove 6. At the same time, the limiting ball 8 squeezes the return spring 7. When the second limiting groove 11 of the limiting block 10 corresponds to the limiting ball 8, the return spring 7 drives the limiting ball 8 to return to its original position. The returned limiting ball 8 squeezes the second limiting groove 11 of the limiting block 10. At this time, the first connecting plate 3 and the second connecting plate 9 are initially connected and fixed, avoiding the occurrence of deviation during the bolt connection of the first pipe 1 and the second pipe 2, which facilitates the docking and fixing of the pipes.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
