Description

Small water pump shock absorption structure

Technical field:

The utility model relates to a small water pump damping structure.

Background technique:

At present, the fixing method of small water pumps on the market is to install rubber pads on the fixing plate for shock absorption, and then fix them through bolt connection. The defect of this structure is that the vibration cannot be completely eliminated. The vibration of the water pump will be transmitted to the machine.

Invention content:

In order to solve the above technical problems, the purpose of this utility model is to provide a small water pump shock absorbing structure, which is simple in structure and reasonable in design, which is beneficial to further reduce vibration.

The utility model is realized through the following technical solutions:

The small water pump shock absorbing structure of the utility model includes a water pump and a base fixed on the machine body. The inner flange is provided with a lower spring under the inner flange, and the lower part of the lower spring extends into the counterbore of the base below the middle seat, and an upper spring is arranged above the inner flange, and the through hole and the counterbore A bolt assembly is threaded inside, and the bolt assembly compresses the upper and lower springs to elastically fix the middle seat on the base.

Further, the above-mentioned bolt assembly includes bolts passing through the counterbore and the through hole from bottom to top, and a positioning ring and a cap nut located on the upper end surface of the through hole.

Further, the above-mentioned positioning ring is in the shape of a cover, its lower end surface rests on the upper surface of the via hole, and the cap nut rests on the upper end surface of the positioning ring.

The principle of this utility model is to suspend and fix the water pump on the base through the upper and lower springs and the middle seat. It is connected by a spring, so when the pump is working, the vibration will be absorbed and eliminated by the upper and lower springs, and the vibration will not be transmitted to the base; thus, the generation of vibration and noise can be greatly reduced.

Description of drawings:

Fig. 1 is an exploded view of the utility model;

Fig. 2 is a structural representation of the utility model;

Fig. 3 is an enlarged view of part A of Fig. 2;

Fig. 4 is a schematic diagram of the three-dimensional structure of the utility model.

Detailed ways:

The small water pump shock absorbing structure of the utility model includes a water pump 1 and a base 2 fixed on the body, the water pump 1 is locked on the middle seat 3, and the middle seat 3 is provided with several through holes 4 in the circumferential direction, and the through holes 4 An inner flange 5 is provided inside, and a lower spring 6 is arranged below the inner flange 5, and the lower part of the lower spring 6 extends into the counterbore 7 of the base 2 below the middle seat, and the upper part of the inner flange 5 is provided with The upper spring 9, the through hole 4 and the counterbore 7 are pierced with a bolt assembly 8, and the bolt assembly 8 compresses the upper and lower springs to elastically fix the middle seat on the base.

Further, for rational design, the above bolt assembly includes a bolt 801 passing through the counterbore 7 and the through hole 4 from bottom to top, and a positioning ring 802 and a cap nut 803 located on the upper end surface of the through hole.

The positioning ring is in the shape of a cover, its lower end surface is placed on the upper surface of the via hole, and the cap nut is placed on the upper end surface of the positioning ring.

The gap between the bolt 801 and the through hole 4 of the middle seat must be large enough. The inner diameter of the through hole 4 of the middle seat can be three times the diameter of the bolt 801. When the water pump is shaking and vibrating at work, the middle seat can not touch the spring except for other parts. touch, reducing vibration conditions. The width of the inner flange 5 is greater than the wire diameter of the spring.

Three groups of through holes, upper and lower springs and bolt assemblies are arranged on the circumference of the middle seat.

The principle of this utility model is to suspend and fix the water pump on the base through the upper and lower springs and the middle seat. It is connected by a spring, so when the pump is working, the vibration will be absorbed and eliminated by the upper and lower springs, and the vibration will not be transmitted to the base; thus, the generation of vibration and noise can be greatly reduced.

The above descriptions are only preferred embodiments of the present utility model, and all equivalent changes and modifications made according to the patent scope of the present utility model shall fall within the scope of the present utility model.
