Based on the embodiments of 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.

[0021] Reference Figure 1 and Figure 2The utility model provides an embodiment: a metering pump with a leak-proof structure, comprising a pump seat body 1, the outer wall of the pump seat body 1 is fixedly connected with a first fixed frame 2, the first fixed frame 2 is provided with a first groove 3, a waterproof pad 4 is installed inside the first fixed frame 2, the outer wall of the waterproof pad 4 is attached to the inner wall of the first groove 3, the outer wall of the first fixed frame 2 is attached with a connecting block 5, the inner thread of the connecting block 5 is connected with a first screw 6, the inner wall of the connecting block 5 is fixedly connected with a connecting pipe 7, the outer wall of the connecting pipe 7 is provided with a thread groove 8, and a fixing component is provided on the upper surface of the pump seat body 1;

[0022] Specifically, the connecting block 5 is attached to the surface of the first fixed frame 2, and the first screw 6 is turned to tightly fix the connecting block 5 and the first fixed frame 2. When fixed inward, the waterproof pad 4 inside the first groove 3 will be compressed, so that the waterproof pad 4 is tightly attached to the outer wall of the connecting block 5, thereby preventing the instability of pressure and flow during transmission, which may affect the stability of the production process and the consistency of product quality.

[0023] Reference Figure 1 and Figure 3 The fixing assembly includes a connecting column 9, the lower surface of the connecting column 9 is attached to the upper surface of the pump seat body 1, and the internal thread of the connecting column 9 is connected with a second screw 10;

[0024] Specifically, the second screw 10 is used to fix the connecting column 9 on the pump seat body 1 to achieve the effect of convenient disassembly.

[0025] Reference Figure 1 and Figure 3 The inner wall of the connecting column 9 is fixedly connected with a hollow column 11, and the outer wall of the hollow column 11 is fixedly connected with a second fixing frame 12; a second groove 13 is opened inside the second fixing frame 12, and a gasket 14 is installed inside the second fixing frame 12; the outer wall of the gasket 14 is attached to the inner wall of the second groove 13, and the inner part of the second fixing frame 12 is threadedly connected with a third screw 15, and the upper surface of the second fixing frame 12 is attached with a motor 16; the inside of the connecting block 5 is fixed with four first screws 6; the inside of the connecting column 9 is fixed with four second screws 10;

[0026] Specifically, the lower surface of the motor 16 is attached to the upper surface of the second fixed frame 12, and the third screw 15 is screwed into the second fixed frame 12. When the third screw 15 is screwed in, the gasket 14 in the second groove 13 is squeezed, so that the gasket 14 and the motor 16 are tightly attached, thereby preventing damage to the equipment, causing performance degradation, damage or even shutdown for maintenance of the equipment, affecting production progress and product quality.

[0027] Working principle: When the metering pump is needed, place the connecting column 9 on the pump seat body 1, and then use the second screw 10 to tighten it, connect the output end of the motor 16 to the machine receiving end inside the hollow column 11, and then the lower surface of the motor 16 is attached to the upper surface of the second fixed frame 12, and the third screw 15 is screwed into the second fixed frame 12, so that the second fixed frame 12 and the motor 16 fit tightly, and when the third screw 15 is screwed in, the gasket 14 inside the second groove 13 will be squeezed, so that the gasket 14 and the motor 16 fit tightly, so as to prevent damage to the equipment, resulting in performance degradation, damage or even shutdown of the equipment for maintenance, affecting the production schedule and product quality, and attach the connecting block 5 to the surface of the first fixed frame 2, and screw the first screw 6, The first screw 6 is used to tightly fix the connecting block 5 and the first fixed frame 2. When fixing inward, the waterproof pad 4 inside the first groove 3 will be compressed, so that the waterproof pad 4 will be tightly attached to the first groove 3 and the outer wall of the connecting block 5 at the same time.
