[0026] Embodiment 2

[0027] See also Figure 4-6 The surface of the rotating rod 13 is slidably connected with a slider 20, and a limiting rod 21 is fixedly installed on the surface of the slider 20. A limiting hole 19 is provided on the side of the mounting seat 1, and a sliding rod 23 is fixedly installed on the bottom surface of the hexagonal head 15. A spring 24 is fixedly installed on the bottom surface of the sliding rod 23. A sliding groove 22 is provided inside the slider 20. The limiting rod 21 cooperates with the limiting groove to limit and fix the position of the rotating rod 13 to avoid accidental rotation of the rotating rod 13 caused by vibration generated by the pump body 3 during operation, affecting the assembly of the mounting plate 2 and the mounting seat 1. The number of limiting holes 19 is two groups, and the two groups of limiting holes 19 are symmetrically distributed on both sides of the U-shaped groove 18, which increases the balance and stability between the slider 20 and the mounting seat 1, thereby improving the stability of the rotating rod 13 inside the U-shaped groove 18.

[0028] Working principle: The pump body 3 is fixedly mounted on the mounting plate 2, ensuring that the adjustment slot 5 on the bottom support plate 4 of the pump body 3 is correctly aligned with the screw hole 6 on the mounting plate 2, and the screw 7 is passed through the adjustment slot 5 to fix it, thereby ensuring the stability and precise positioning of the pump body 3, and facilitating personnel to fine-tune the position of the pump body 3 according to the actual installation position. The housing 25 is placed inside the groove 16 so that the mounting plate 2 can be docked with the mounting seat 1. At this time, one end of the rotating rod 13 extending to the outside of the housing 25 will be placed inside the U-shaped groove 18. By sliding the slider 20, the sliding rod 23 squeezes the spring 24 through the sliding groove 22 inside the slider 20, so that the slider 20 is away from the housing 25, so that the rotating rod 13 has space to be completely placed inside the U-shaped groove 18. The hexagonal head 15 is rotated with a tool so that the hexagonal head 15 drives the rotating rod 13 to rotate, and the rotating rod 13 drives the active bevel gear 14 to rotate inside the housing 25. Thus, the active bevel gear 14 can drive the driven bevel gear 9 to rotate, and then the driven bevel gear 9 drives the screw 8 to rotate inside the housing 25. At this time, the screw 8 rotates inside the pressure plate 10, so that the pressure plate 10 can move on the surface of the screw 8, so that the pressure plate 10 slides inside the housing 25, and the pressure plate 10 drives the insertion rod 11 to pass through the perforation 12, so that the insertion rod 11 can be inserted into the slot 17, so that the mounting plate 2 can be stably fixed on the mounting seat 1, thereby realizing the rapid disassembly and assembly of the diaphragm pump, facilitating personnel to maintain the diaphragm pump, and improving the disassembly and assembly efficiency of the diaphragm pump. After installation, the slider 20 is released, and the slider 20 is restored to its original position under the elastic force of the spring 24, so that the limiting rod 21 on the slider 20 can be inserted into the limiting holes 19 on both sides of the U-shaped groove 18, so as to realize the current fixation of the rotating rod 13, and avoid the vibration generated by the pump body 3 during the working process, which causes the rotating rod 13 to rotate accidentally, affecting the assembly of the mounting plate 2 and the mounting seat 1.
