Description

Technical Field

[0001] The utility model relates to an impeller, in particular to a water-cooled impeller assembly. Background Art

[0002] The centrifugal pump works by rotating the impeller to make the water centrifugal. Before starting the water pump, the pump casing and the water suction pipe must be filled with water, and then the motor is started so that the pump shaft drives the impeller and water to rotate at high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller, and flows into the water pressure pipeline of the water pump through the flow channel of the volute pump casing. The impeller needs to maintain sufficient stability during high-speed rotation, otherwise it is easy to fall off and then be damaged, making the pump unable to operate normally.

[0003] The current impeller assembly includes a fan blade, which needs to be assembled on a base. Since the fan blade and the base are two independent components, the fan blade and the base are usually bonded together by glue. When the fan blade is rotated by a driver, it is easy to fall off and has poor stability. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a water-cooled impeller assembly which is easy to assemble and has stable connection.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A water-cooled impeller assembly includes a base and a fan blade. The base has a connecting cylinder and an end face. The end face is arranged at one end of the connecting cylinder. A snap hole is arranged on the end face. A snap piece is arranged on the fan blade. The snap piece is inserted into the snap hole and fixed to form a fixed connection between the fan blade and the base. The shape of the snap hole matches the shape of the snap piece.

[0007] The fan blade is provided with a fixing portion, and the buckle is installed on the fixing portion.

[0008] The buckle comprises a protruding portion and a transverse clamping portion arranged on the protruding portion, the width ratio of the transverse clamping portion to the protruding portion is greater than 1, and the fixing portion is inserted into the protruding portion.

[0009] The transverse clamping portion is circular.

[0010] The buckle piece and the buckle hole are of interference fit structure.

[0011] The end surface and the connecting cylinder are an integrally formed structure.

[0012] The end surface is formed by horizontally extending outward at the port connected to the cylinder.

[0013] The fixing portion is integrally formed on the fan blade.

[0014] Compared with the prior art, the utility model has the following beneficial technical effects:

[0015] By fixing the snap fasteners on the fan blades, a snap connection is achieved with the base to form a radial fixing force. During the rotation of the fan blades, the centrifugal force generated is a radial force, thereby ensuring a secure connection between the fan blades and the base through the radial fixing force, and assembling is easy.

[0024] refer to Figure 1-3 As shown, a water-cooled impeller assembly includes a base 1 and a blade 2, wherein the base has a connecting cylinder 3 and an end face 4, wherein the end face 4 is arranged at one end of the connecting cylinder 3, wherein a snap hole 6 is arranged on the end face 4, and a snap member 5 is arranged on the blade 2, wherein the snap member 5 is inserted into the snap hole 6 and fixed, thereby forming a fixed connection between the blade 2 and the base 1, wherein the shape of the snap hole matches the shape of the snap member. By utilizing the snap installation structure of the snap member and the snap hole, a tensioning force is formed between the blade and the base in the radial direction, and during the rotation process, the blade and the base will not fall off due to the centrifugal force generated. There are multiple blades, and in order to ensure the stability of the installation, a snap member is arranged on each blade, and the number of the snap holes arranged on the end face is the same as that of the snap members, which is a one-to-one corresponding structure. Since the orientations of different blades are different, the orientations of the snap holes will also be different.

[0025] The fan blade 2 is provided with a fixing portion 7, and the snap-fit ​​member 5 is mounted on the fixing portion 8. The fixing portion 8 is a raised strip-shaped member and is an integrally formed structure with the fan blade.

The width ratio of the transverse clamping portion 9 to the protruding portion 8 is greater than 1. The fixing portion 7 is inserted into the protruding portion 8 to form a tight fit.

[0027] The transverse clamping portion 9 is circular, and the protrusion 8 is in a strip shape matching the fixing portion 7. The buckle hole is a strip hole, and a circular groove cavity is set in the middle area of ​​the hole to match the transverse clamping portion, and only the protrusion passes through the buckle hole, while the transverse clamping portion is supported by the circular groove cavity.

[0028] The buckle piece and the buckle hole are of interference fit structure.

[0029] The end surface and the connecting cylinder are an integrally formed structure. The end surface is horizontally extended outward at the port of the connecting cylinder to form an outward-turned edge structure.

[0030] When assembling the utility model, the fixing part on the fan blade is first aligned with the buckle hole of the base, the fixing part is inserted into the buckle hole, and then the protrusion of the buckle is inserted into the buckle hole from top to bottom, and the fixing part is inserted into the inside of the protrusion, and pressed downward to make the transverse clamping part fastened in the buckle hole, and the assembly is completed, so that the fan blade is subjected to a fixing force in the radial direction, and the fixing part and the protrusion are tightly matched, and will not fall off easily without using external force.
