[0059] Example 2:
[0060] A method for assembling a self-locking piping system, the piping system including the piping system described in Embodiment 1, the assembly method comprising the following steps:
[0061] S1. Place pipe A. The spring clip 2 inside pipe A is in the retracted state. Put the rubber sealing ring A on pipe B. Connect the end of pipe B with the rubber sealing ring A to pipe A. The spring clip 2 extends into the receiving area to achieve the initial fixation of pipe A and pipe B.
[0062] S2. Install the rubber sealing ring B along the axial direction of pipe B until one end of the rubber sealing ring B moves to the corresponding position on pipe A; then, fit the two annular parts of the clamping buckle onto pipe B, and connect them by using the connecting lug screw 16 and connecting lug nut 17 to the connecting lug 14 on the annular part to assemble the clamping buckle. Move the clamping buckle along the axial direction of pipe B until one end of the clamping buckle moves to the corresponding position on pipe A. Use the connecting piece to pass through the clamping buckle, the rubber sealing ring B, and the corresponding position on pipe A to further tighten pipe A and pipe B.
[0063] S3. Repeat steps S1-S2 until the piping system reaches the required length.
[0064] Specifically, in practical applications, first, pipe A is placed. At this time, the spring clips along the inner edges of the front and rear openings of pipe A are compressed under the limiting action of the lever. Next, the rubber sealing ring A is fitted onto pipe B along the outer side of the small ring A5, pressing against the opening of pipe B. The special rubber ring is fixed by the friction between the inner wall of the rubber sealing ring A and the outer surface of pipe B. Then, pipe B with the rubber sealing ring A fitted is connected to pipe A. The length of pipe B entering pipe A along its diameter is just enough to allow the spring clip 2 to engage with the small ring A5 in its extended state. Next, a technician enters pipe A and pulls out the lever, causing the compressed spring clip 2 to extend. At this point, the spring clip 2 is precisely engaged with the small ring A5, and the connection between pipe A and pipe B is complete.
[0065] Specifically, in practical applications, since the inner diameter of the rubber base 8 on the rubber sealing ring B is the same as the outer diameter of pipe B, and the outer diameter is the same as the outer diameter of pipe A, the rubber sealing ring B is fitted onto pipe B from the unconnected side, with its sealing ring B7 facing pipe A and the connected side of pipe B. It is then fitted along the pipe diameter direction at the pipe connection, aligning its screw positioning hole A9 with the threaded groove 3 on pipe A. The two annular parts of the clamping clip are fitted onto pipe B, and the connecting ears 14 on the annular parts are connected using the connecting ear screw 16 and connecting ear nut 17, thus assembling the clamping clip. The clamping clip is then moved axially along pipe B until it is fitted onto the rubber sealing ring B, with the screw positioning hole B10 aligned with the threaded groove 3 on pipe A. At this point, the screw positioning holes A9, B10, and 3 are aligned in pairs. Finally, it is fixed with screw 13, significantly improving the overall integrity and sealing performance.
[0066] Then connect pipe A and pipe B according to the above steps, during which rubber sealing ring A, rubber sealing ring B and clamping clips are installed to complete the connection of the entire pipeline.
[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
