Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Pipeline connection is the process of fixing different pipe sections or pipes with other components (such as valves, pumps, etc.) to ensure that the fluid can pass through the entire pipeline system smoothly and without leakage. However, when connecting pipes, multiple components need to be manually operated to achieve the connection. At the same time, due to the different diameters and materials of different pipes, as well as factors such as lofting errors, processing accuracy and running deformation, specific adapters are required, which lacks versatility and increases the complexity and cost of the connection. Therefore, a universal experimental equipment connecting pipe structure is urgently needed.

[0033] like Figure 1-Figure 3As shown, the utility model provides a universal experimental equipment connecting pipe structure, including: a first connecting pipe 10, a second connecting pipe 20, a first spring 30 and a disassembly member 40.

[0034] The outer wall of the first connecting tube 10 is provided with a first serrated portion 11; the outer wall of the second connecting tube 20 is provided with a second serrated portion 21, and the first serrated portion 11 is matched with the second serrated portion 21; the first spring 30 is provided on the outer wall of the second connecting tube 20, and the first spring 30 is used to connect the first connecting tube 10 with the second connecting tube 20; the disassembly part 40 is provided on the outer wall of the first connecting tube 10, and the disassembly part 40 is used to disassemble the first serrated portion 11 and the second serrated portion 21.

[0035] In some embodiments of the present application, the first connecting tube 10 includes: a first connecting portion 12, a first serrated portion 11 is arranged on the inner side of the first connecting portion 12, a disassembly component 40 is arranged on the outer side of the first connecting portion 12, and the disassembly component 40 penetrates the first connecting portion 12 and extends into the inner side of the first connecting portion 12; and a second connecting portion 13, and the second connecting portion 13 is connected to the first connecting portion 12.

[0036] In some embodiments of the present application, the second connecting tube 20 includes: a third connecting portion 22, on which a second serrated portion 21 is arranged; a fourth connecting portion 23, which is arranged on the outer wall of the second connecting tube 20 and connected to the third connecting portion 22, and a first fixing ring 31 is arranged on the fourth connecting portion 23, and the first fixing ring 31 is fixedly connected to one side of the first spring 30.

[0037] In this embodiment, the first serrated portion 11 is arranged on the inner side of the first connecting portion 12 to facilitate the fit with the second serrated portion 21, wherein the serrations of the first serrated portion 11 face inward and the serrations of the second serrated portion 21 face outward. When the first connecting tube 10 is connected to the second connecting tube 20, the second serrated portion 21 enters the second serrated portion 21 along the serration direction until it is completely fit with the second serrated portion 21. When the first connecting tube 10 and the second connecting tube 20 are subjected to external force, the two are not easily separated due to the presence of the serrations, thereby providing a layer of protection for the connection of the pipelines.

[0038] In some embodiments of the present application, a second fixing ring 32 is provided on the first connecting portion 12 , a hook is provided on one side of the first spring 30 , and the first spring 30 is connected to the second fixing ring 32 via the hook.

[0045] In some embodiments of the present application, a first sealing ring 50 is provided at the connection between the outer wall of the first connecting pipe 10 and the outer wall of the second connecting pipe 20 .

[0046] In some embodiments of the present application, a second sealing ring 60 is provided at the connection between the second connection portion 13 and the fourth connection portion 23 .

[0047] In this embodiment, the first sealing ring 50 and the second sealing ring 60 are provided to ensure the sealing performance of the connection between the first connecting pipe 10 and the second connecting pipe 20 .

[0048] To further illustrate the utility model, the use principle of the present application is first explained.

At this time, the first serrated portion 11 and the second serrated portion 21 fit each other, and the hook of the first spring 30 is connected to the second fixing ring 32 to achieve the fixed connection between the first connecting tube 10 and the second connecting tube 20; when disassembly is required, the pressing block 41 of the disassembly member 40 is pressed, and the limiting block and the connecting sleeve 43 move inward accordingly, driving the anti-slip head 46 on the disassembly block 44 to contact the second serrated portion 21, and continue to press downward to separate the second serrated portion 21 from the first serrated portion 11, and apply an outward force to the first connecting tube 10 and the second connecting tube 20 to achieve the separation of the two.

[0049] The utility model realizes the connection of pipelines by improving the first connecting pipe 10 and the second connecting pipe 20 without adding an additional adapter, thereby reducing the cost of pipeline connection and improving the efficiency and convenience of pipeline connection. By setting a serrated portion, the first connecting pipe 10 is fixedly connected to the second connecting pipe 20, and the serrated portions are mutually matched. When the two are subjected to opposite external forces, the serrated portions are set so that the two are not easy to separate, thereby ensuring the tightness of the pipeline connection and improving the stability of the pipeline connection. A disassembly part is provided. When the pipeline needs to be disassembled, the pressing block 41 is pressed down to press the second serrated portion downward and separate from the first serrated portion, thereby realizing the disassembly of the pipeline and facilitating the replacement of the pipeline.
