[0022] Specifically, the sealing groove 2 is provided to serve as a placement for the rubber pad 16, the slide groove 3 and the slider 5 are provided to facilitate installation of the installation box 4 inside the first shell 1, and the installation position of the installation box 4 is effectively fixed, the installation groove 6 is provided to facilitate installation of the gear mechanism inside the installation box 4, the water outlet groove 7 and the water inlet groove 8 are provided to facilitate the in and out of liquid flow, and the screws 10 can stably fix the first shell 1 and the second shell 9.

[0023] The gear mechanism includes a driving gear 11, the outer wall of which is installed inside the mounting groove 6, a driving shaft 12 is installed inside the driving gear 11, a driven gear 13 is meshed and connected at the teeth of the driving gear 11, the outer wall of the driven gear 13 is installed inside the mounting groove 6, a driven shaft 14 is fixedly connected inside the driven gear 13, the outer wall of the driven shaft 14 and the outer wall of the driving shaft 12 are both rotatably connected to the inside of the mounting box 4, both ends of the driven shaft 14 are rotatably connected to the inside of the first shell 1 and the inside of the second shell 9, one end of the driving shaft 12 is rotatably connected to the inside of the first shell 1, and the outer wall of the other end of the driving shaft 12 is rotatably connected to the inside of the second shell 9.

[0024] Specifically, the driving shaft 12 is driven to rotate by an external device motor, and the driving shaft 12 drives the driving gear 11 in the installation box 4 to rotate, and the driving gear 11 rotates to drive the driven gear 13 to rotate, and the driven gear 13 rotates to rotate the driven shaft 14. The driving shaft 12 and the driven shaft 14 rotate inside the installation box 4, the first shell 1 and the second shell 9. When different output flow rates are required during use, the output flow rate of the gear pump can be changed by replacing the gears. Gears with larger diameters usually produce larger output flow rates, while gears with smaller diameters produce smaller output flow rates.

[0025] Reference Figure 1-Figure 3 Screws 15 are threadedly connected to both sides of the interior of the first shell 1, and rubber pads 16 are fixedly connected to the adjacent ends of the two screws 15. The outer wall of the rubber pad 16 is installed in the sealing groove 2. A first through hole 17 is opened in the interior of one screw 15, and a second through hole 18 is opened in the interior of the other screw 15. Nuts 19 are threadedly connected to the outer wall of the screw 15, and the nuts 19 are installed on the outer wall of the first shell 1. A rotating ring 20 is fixedly connected to the adjacent sides of the two nuts 19. Rotating grooves 21 are opened on both sides of the interior of the first shell 1, and the outer wall of the rotating ring 20 is rotatably connected to the inner wall of the rotating groove 21.

[0026] Specifically, the position of the nut 19 is effectively fixed by setting the rotating circle 20 and the rotating groove 21, so that the nut 19 can only rotate on the first shell 1. By rotating the nut 19, the screw 15 can be driven to rotate inside the first shell 1. The movement of the screw 15 can drive the rubber pad 16 to move in the sealing groove 2, and at the same time approach or move away from the installation box 4. The rubber pad 16 is set as a circular ring. When the rubber pad 16 is tightly fitted with the installation box 4, it can effectively play a transition role between the water outlet groove 7 and the first through hole 17, the water inlet groove 8 and the second through hole 18, and effectively seal the water outlet groove 7 and the first through hole 17, the water inlet groove 8 and the second through hole 18 to prevent water leakage.

[0027] Reference Figure 1 A plurality of resistance grooves 22 are provided inside the nut 19 .

[0028] Specifically, the resistance groove 22 can effectively increase the resistance when the nut 19 is rotated.

[0029] Working principle: By sliding the slider 5 on the installation box 4 into the corresponding slide groove 3, the installation box 4 enters the first housing 1, and at the same time, one end of the driven shaft 14 and the driving shaft 12 enter the first housing 1 to maintain the stability of the driven shaft 14 and the driving shaft 12 when they rotate. Then, the second housing 9 is installed on one side of the first housing 1 by the screw 10, and at the same time, the driven shaft 14 and the driving shaft 12 enter the second housing 9. By rotating the nut 19, the screw 15 is driven to rotate inside the first housing 1, so that the screw 15 can drive the rubber pad 16 to fit tightly with the installation box 4, and the rubber pad 16 is connected to the water inlet trough 8 and the water outlet trough. 7 corresponds to each other, so that the water outlet groove 7 and the first through hole 17, the water inlet groove 8 and the second through hole 18 can be effectively sealed to prevent water leakage. The external device motor can be connected to the driving shaft 12 to drive the driving gear 11 to rotate and then drive the driven gear 13 to rotate. When the required output flow rate is different, the screw 10 can be disengaged from the inside of the first shell 1 by twisting the screw 10, so that the second shell 9 and the first shell 1 can be separated, and then the installation box 4 and the gear mechanism can be disassembled to achieve the required output flow rate, so that it is possible to achieve without replacing the shell, effectively improving the versatility of the shell.
