Further, fixing holes for bolts to pass through are formed at the four corners of the base 2, which facilitates the connection between the base 2 and the placement surface.

[0033] Referring to Figures 1-2, a feed pipe 3 and a discharge pipe 4 are successively installed at the top and bottom on one side of the diaphragm pump body 1. Connection pipes 5 are fixedly installed at the ports of the feed pipe 3 and the discharge pipe 4. The feed pipe 3 and the discharge pipe 4 are fixedly connected to the connection pipes 5 through connecting flanges. A strengthening mechanism for strengthening the connection of the connection pipes 5 is installed on the base 2. The strengthening mechanism includes a vertical rod 6 installed on the base 2, two pipe fixing mechanisms slidably installed at the top and bottom of the vertical rod 6, and a shock absorption and buffering mechanism installed inside the vertical rod 6. Two installation grooves 7 are opened inside the vertical rod 6. A moving block 8 is slidably installed inside the installation grooves 7. Two shock absorption and buffering mechanisms are installed inside each installation groove 7. The two shock absorption and buffering mechanisms are symmetrically installed on both sides of the moving block 8. The pipe fixing mechanism is installed on the moving block 8. By fixing the connection pipes 5 connected to the feed pipe 3 and the discharge pipe 4 on the pipe fixing mechanism, and the pipe fixing mechanism is installed on the shock absorption and buffering mechanism. In this way, when the diaphragm pump body 1 operates and generates vibrations, the shock absorption and buffering mechanism inside the vertical rod 6 can absorb and buffer the vibrations of the connection pipes 5, thereby reducing the vibrations at the connection points of the connection pipes 5 with the feed pipe 3 and the discharge pipe 4, and improving the stability of the connection pipes 5 during connection.

[0034] Refer to Figures 1-3 , the shock absorption and buffering mechanism includes a telescopic damping rod 14 fixedly installed between the inner wall of the installation groove 7 and the moving block 8, and a shock absorption spring 15 sleeved on the surface of the telescopic damping rod 14.
