DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1 , Figure 2 As shown, the utility model provides a technical solution: comprising a groove connection component 1, a No. 1 pipe 2, a No. 2 pipe 5 and a sealing ring 7, wherein the No. 1 pipe 2 and the No. 2 pipe 5 are connected through the groove connection component 1, and the sealing ring 7 is arranged between the No. 1 pipe 2, the No. 2 pipe 5 and the groove connection component 1; the groove connection component 1 comprises a movable buckle 14, wherein a through groove 17 is provided inside the movable buckle 14, and one end of the movable buckle 14 is arranged into a conical structure, wherein the diameter of the conical structure is greater than the diameter of the end of the movable buckle 14 away from the conical structure, and long strip grooves 18 are provided inside the movable buckle 14 and on the outer periphery of the through groove 17 at equal intervals, and the length of the long strip groove 18 runs through the conical structure The end of the movable buckle 14 is elastic, and the groove connection assembly 1 also includes an upper valve 9, a lower valve 10 and a nut 13. Both ends of the upper valve 9 are fixedly connected to a fixed block 11, and the ends of the two movable buckles 14 are respectively fixedly connected to the two ends of one side of the fixed block 11. A spring 12 is arranged between one side of the nut 13 and the fixed block 11. A threaded groove 19 is opened inside the nut 13. The outer peripheral thread of the movable buckle 14 is connected to the inside of the threaded groove 19. Both ends of the lower valve 10 are fixedly connected to a limiting block 21. The inside of the limiting block 21 is slidably connected to two T-shaped rods 15, and the ends of the T-shaped rods 15 extend to the inside of the corresponding through groove 17.

[0023] In this embodiment, the outer circumference of the T-bar 15 and the through slot 17 are both provided with threads, and the diameter of the T-bar 15 is slightly larger than the diameter of the through slot 17 before deformation. When the T-bar 15 is inserted into the through slot 17, the movable buckle 14 is deformed through the internal long slot 18. This design allows the movable buckle 14 to better fit the T-bar 15 when subjected to external force, so that the movable buckle 14 is deformed with a larger diameter, and self-locking is achieved under the cooperation of the threads of the two, so that the T-bar 15 can maintain a certain stability, and then the nut 13 is rotated to resist the deformation of the movable buckle 14, and the T-bar 15 can be locked. At the same time, the spring 12 can provide a certain elastic force to keep the nut 13 stable. This design simplifies the traditional pipe connection method, is more resistant to vibration and external force, and the installation and disassembly process is faster and more convenient. Especially in an environment where space is small or it is inconvenient to use tools, it can significantly improve work efficiency.

[0024] Example 2

[0025] like Figure 1 , Figure 2 As shown, the diameter of the spring 12 is larger than the diameter of the thread groove 19, and the elastic force of the spring 12 is much larger than the gravity of the nut 13, which means that even in the case of vibration, the spring 12 can keep the connection part under a certain tension, reducing the possibility of loose connection due to vibration;

[0026] Two rubber sheets 16 are fixedly connected to the outer periphery of the T-shaped rod 15. The rubber sheets 16 can provide greater friction when the T-shaped rod 15 is clamped, thereby improving the stability between the connection components and reducing looseness caused by vibration or impact;

[0027] A No. 1 pressure groove 4 is provided on the outer periphery of the bottom of the No. 1 pipe 2, and a No. 2 pressure groove 6 is provided on the outer periphery of the top of the No. 2 pipe 5. A flange 3 is fixedly installed on the outer periphery of the No. 1 pipe 2. Two spacer rings 8 are symmetrically fixedly connected inside the sealing ring 7. The spacer rings 8 are symmetrically fixedly connected inside the sealing ring 7, which not only helps to maintain the fixed position of the sealing ring 7, but also can improve the compression resistance of the overall structure and reduce deformation. An adaptation groove 20 is provided inside the upper valve 9 and the lower valve 10. The bottom of the No. 1 pipe 2 and the top of the No. 2 pipe 5 are both adapted to the inner wall of the sealing ring 7. The adaptation groove 20, the No. 1 pressure groove 4 and the No. 2 pressure groove 6 are adapted. Through the adaptive design of the No. 1 pressure groove 4, the No. 2 pressure groove 6 and the adaptation groove 20, a stable sealing structure can be formed at the connection between the No. 1 pipe 2 and the No. 2 pipe 5 to avoid medium leakage.

[0028] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the utility model.
