Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 and Figure 2 In this embodiment: a high-pressure resistant diaphragm pump liquid pump comprises a mounting cover 12, a plurality of evenly distributed cross nails 11 are threadedly connected around the mounting cover 12, a pressure-resistant tube 13 is threadedly connected to the bottom of the cross nail 11, a liquid outlet pipe 2 is sleeved on the outer periphery of the pressure-resistant tube 13 on one side, a liquid inlet pipe 8 is sleeved on the outer periphery of the pressure-resistant tube 13 away from the liquid outlet pipe 2, a knob 9 is threadedly connected to the outer periphery of the liquid inlet pipe 8 and the side of the liquid outlet pipe 2 close to the pressure-resistant tube 13, a plurality of evenly distributed protrusions 10 are fixedly connected to the outer periphery of the knob 9, and a booster component is arranged on the opposite side of the knob 9.

[0025] Specifically, the mounting cover 12 and the pressure-resistant tube 13 are installed together by means of a cross nail 11. The pressure-resistant tubes 13 on both sides are provided with a liquid inlet pipe 8 and a liquid outlet pipe 2. The liquid enters the cavity from the liquid inlet pipe 8 and is discharged from the liquid outlet pipe 2. The staff rotates the knob 9 to deform the liquid inlet pipe 8, the liquid outlet pipe 2 and the pressure-resistant tube 13 so as to achieve a sealing effect. The function of the protrusion 10 is to facilitate the staff to rotate the knob 9.

[0029] Specifically, the driving motor 1 drives the eccentric ring 20 to rotate, so that the connecting ring 17 in the mounting shell 4 makes up and down reciprocating motion. The connecting ring 17 is connected to the diaphragm 15 by the threaded nail 14, thereby driving the diaphragm 15 to vibrate in the cavity, increasing the liquid pressure in the cavity, and the bearing 5 reduces the friction of the driving motor 1 when rotating, ensuring smoother rotation.
