[0004] With regard to the above-mentioned related technologies, the inventor believes that the sound insulation shell and the sound insulation cover are connected by bolts, and the sound insulation cover is inconvenient to disassemble and assemble, which is time-consuming and labor-intensive, and is not convenient for quick maintenance of the motor. At the same time, after the motor is used for a long time, the bolts are prone to loosening, and the noise generated by the motor is easily dissipated from the gap between the sound insulation shell and the sound insulation cover, resulting in limited noise reduction effect, and therefore needs to be improved. Summary of the invention

[0005] In order to improve the convenience of disassembling and assembling the sound insulation cover, facilitate quick maintenance of the motor, and at the same time improve the noise reduction effect of the motor operation, the present application provides a noise reduction motor.

[0006] The noise reduction motor provided in this application adopts the following technical solution:

[0007] A noise reduction motor comprises a sound insulation shell and a body fixedly arranged in the sound insulation shell, the sound insulation shell is connected to a sound insulation cover, and a driving shaft of the body passes through the sound insulation cover; a group of mounting rods are symmetrically arranged at one end of the sound insulation shell facing the sound insulation cover, and the mounting rods are integrally formed with the sound insulation shell; a mounting hole for inserting the mounting rod is penetrated through the surface of the sound insulation cover, and the inner side wall of the mounting hole and the outer side wall of the mounting rod are in contact with each other; a group of embedding grooves are symmetrically opened on the outer side wall of the mounting rod along its length direction, and a limit block is rotatably arranged in the embedding groove along its length direction, and an abutment block is arranged in the embedding groove, and the abutment block abuts against a side of the limit block away from the embedding groove, and the end of the limit block abuts against the surface of the sound insulation cover; a rubber sound insulation pad is arranged between the sound insulation cover and the sound insulation shell, and the rubber sound insulation pad is fixedly arranged on the side of the sound insulation cover facing the sound insulation shell.

[0008] By adopting the above technical solution, when installing between the sound insulation cover and the sound insulation shell, the limit block is first rotated into the embedding groove. At this time, the installation rod can be passed through the installation hole, and the installation rod slides in the installation hole, and the sound insulation cover is slid to the end wall of the sound insulation shell. Then, the sound insulation cover is pressed, and the rubber sound insulation pad is deformed. At this time, the limit block can be rotated out of the embedding groove, and then the rubber sound insulation pad restores its deformation, and the abutment block abuts against one side of the limit block, so that the end of the limit block abuts against the surface of the sound insulation cover, and the limit block limits the sound insulation cover, thereby fixing the installation rod in the installation hole. , to achieve the installation between the sound insulation cover and the sound insulation shell. When the body in the sound insulation shell needs to be repaired, the user presses the limit block with his hand, the rubber sound insulation pad is deformed under pressure, and the limit block slides on the surface of the sound insulation cover, and finally rotates the limit block into the embedded groove. At this time, the sound insulation cover is lifted again, and the mounting rod and the mounting hole are separated from each other, and the sound insulation cover can be quickly removed from the sound insulation shell, which is convenient for rapid maintenance of the motor. The operation is convenient and quick. At the same time, the rubber sound insulation pad seals the gap between the sound insulation shell and the sound insulation cover, thereby improving the noise reduction effect of the equipment.

[0009] Optionally, a spring sheet is fixedly provided in the embedding groove, and two ends of the spring sheet respectively abut against the bottom wall of the embedding groove and the outer side wall of the limiting block, and the spring sheet drives the limiting block to rotate in a direction away from the embedding groove.

[0010] By adopting the above technical solution, when installing the sound insulation cover, the limit block first abuts against the sound insulation cover, at which time the spring sheet contracts and the limit block automatically rotates into the embedding groove. When the sound insulation cover slides to the end of the sound insulation shell, the sound insulation cover is pressed, and under the elastic force of the spring sheet, the limit block automatically rotates out of the embedding groove, so that there is no need to manually rotate the limit block when installing the sound insulation cover, thereby improving the convenience of operation.

[0011] Optionally, a sleeve is rotatably arranged on the end wall of the mounting rod, and a sliding groove which is interconnected with the embedding groove is opened on the end wall of the mounting rod.

The abutment rod drives the abutment block to abut against the surface of the limit block, and the abutment force between the abutment block and the limit block is adjusted, thereby increasing the abutment force between the limit block and the surface of the sound insulation cover, thereby making the connection strength between the sound insulation cover and the sound insulation shell higher.

[0013] Optionally, one end of the abutment block away from the abutment rod is arc-shaped.

[0014] By adopting the above technical solution, the contact area between the abutment block and the limit block is increased.

At the same time, when the machine body vibrates, the sound insulation shell is not easy to vibrate, thereby improving the shock absorption effect.
