Description

Technical Field

[0001] This utility model belongs to the field of asynchronous motor technology, and in particular relates to single-phase asynchronous motors. Background Technology

[0002] Single-phase asynchronous motors are a common type of AC motor, widely used in household appliances, small mechanical equipment, and other applications. They are characterized by their simple structure and low cost, but their starting torque is relatively small, and they usually require an auxiliary starting device. The existing single-phase asynchronous motor is connected to the workbench through the mounting holes on the bottom mounting plate. However, the position of the mounting holes on the mounting plate is fixed, but the position and diameter of the mounting holes on different workbench are different. This makes it impossible for the single-phase asynchronous motor to be adapted to different workbench, affecting the installation and use of the single-phase asynchronous motor.

[0003] For this purpose, we offer single-phase asynchronous motors. Utility Model Content

A movable ring is slidably installed on the upper end of the adjusting groove, and the assembly is movably inserted inside the movable ring.

[0008] The present invention is further configured such that a clamping plate is fixedly installed on the outer side of the assembly, and clamping teeth are fixedly installed on both sides of the clamping plate. The clamping teeth are engaged with the limiting toothed strip. A support spring is sleeved on the surface of the assembly, and the two ends of the support spring are fixedly connected to the moving ring and the clamping plate, respectively.

[0009] The present invention is further configured such that the adjusting structure includes a movable groove, the movable groove is formed inside the mounting ring, the outer ring of the mounting ring is provided with an annular groove, and a rotating ring is rotatably mounted inside the annular groove.

[0010] The present invention is further configured such that a fixed sleeve is fixedly installed on both sides inside the movable groove, and a movable sleeve is movably fitted on the outside of the fixed sleeve, and four clamps located on the same side are fixedly connected to the movable sleeve.

[0011] The present invention is further configured such that an adjusting screw is rotatably installed inside the fixed sleeve, one end of the adjusting screw is movably inserted into the inside of the annular groove and is equipped with a bevel gear, the inner ring of the rotating ring is provided with a transmission gear ring, the transmission gear ring meshes with the bevel gear, and an adjusting sleeve is movably sleeved on the outer side of the adjusting screw, the adjusting sleeve being connected to the movable sleeve.
