Moreover, first feature "on", "above" and "upper surface of" second feature includes that first feature is directly above and obliquely above second feature, or only indicates that horizontal height of first feature is higher than second feature. First feature "under", "below" and "under surface of" second feature includes that first feature is directly below and obliquely below second feature, or only indicates that horizontal height of first feature is less than second feature.

[0037] In the description of the embodiment, the orientation or position relationship of the terms "upper", "lower", "left", "right" and the like is based on the orientation or position relationship shown in the drawings, only for the convenience of description and simplification of operation, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second" are only used to distinguish in description, and have no special meaning.

[0038] The embodiment provides a plug-in structure, as shown in the drawing, Figures 1-5 The plug-in structure includes a first component 100, a second component 200 and a conical single pin 300, one end of the first component 100 is provided with a first pipe joint 110, the first pipe joint 110 is provided with a conical hole 111 penetrating the inner wall of the first pipe joint 110, one end of the second component 200 is provided with a second pipe joint 210, the second pipe joint 210 is inserted into the first pipe joint 110, and the outer wall of the second pipe joint 210 is provided with a limiting groove 211; the conical single pin 300 is inserted into the conical hole 111, and at least part of the conical single pin 300 is located in the limiting groove 211, so that the second pipe joint 210 is limited in the axial direction of the first pipe joint 110. The structure that the conical single pin 300 is inserted into the conical hole 111 can form closer contact when stressed, provide stronger locking force, effectively prevent the pin from loosening or falling off, and thus the stability and reliability of the plug-in structure are significantly improved; and the plug-in structure does not need to rely on installation tools, can quickly complete pipeline butt joint, is simple and easy to operate, and greatly improves installation and maintenance efficiency.

[0039] Optionally, as shown in the drawing, Figure 2 The second pipe joint 210 is inserted into the first pipe joint 110, the conical hole 111 is located on the outer wall of the second pipe joint 210 along the tangential direction of the second pipe joint 210, the volume of the first pipe joint 110 is reduced, and the overall first pipe joint 110 and second pipe joint 210 assembly structure are more compact.

The boss 130 is designed to increase the thickness of the material around the tapered hole 111, effectively improving the anti-deformation ability of the first pipe joint 110 under stress conditions. Especially when the pipe connection is subjected to external force or vibration, the boss 130 can disperse the stress borne by the tapered single pin 300, avoiding damage to the tapered hole 111 due to excessive stress concentration, thereby improving the strength and stability of the overall structure.

[0041] Optionally, the two ends of the boss 130 are respectively provided with a first plane 131 and a second plane 132, and the first end and the second end of the tapered single pin 300 protrude from the first plane 131 and the second plane 132, respectively.

The flat structure design provides a larger stress area, facilitating the use of heavy objects to knock the second end of the tapered single pin 300 during installation by construction personnel, ensuring that the tapered single pin 300 is in interference fit with the wall of the tapered hole 111, and when disassembling, the first end of the tapered single pin 300 is knocked with a heavy object, and the tapered single pin 300 is pulled out of the tapered hole 111, simplifying the disassembly steps and improving the disassembly efficiency.

[0044] Optionally, the taper of the tapered single pin 300 and the tapered hole 111 is 0.05-0.2, which can provide a gradual pressing effect, and after the tapered single pin 300 is inserted, a good clamping force is formed in the radial direction, achieving stable locking.

[0045] It should be noted that the taper of the tapered single plug 300 = |upper base diameter - lower base diameter| / height of the tapered single plug.
