Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to a self-balancing rotating part. Background Technology

[0002] A measuring switch is a device used to detect and control electrical signals. It is widely used in industrial automation, electronics manufacturing, and power systems. A measuring switch is a measuring element that converts a measured physical quantity, such as position, speed, or angle, into a switching quantity. It controls the switching state of the electrical signal through the movement of mechanical parts. When the mechanical parts move to a certain position, they trigger a change in the electrical signal, thereby controlling the electrical equipment. Common measuring switch control parts include toggle switches and knob switches. In knob switches, the rotating part is the key element controlling the variable. Currently, most common rotating parts in measuring switches consist of a knob with a rotatable threaded rod connected to the center. During prolonged use, because only the center is fixed, the knob is prone to wobbling, affecting normal operation. Utility Model Content

[0009] Preferably, slide rails are provided around both sides of the tank, and the pulleys are rotatably attached to the slide rails on both sides of the tank.

[0010] The beneficial effects of this utility model are as follows: By setting a top cover and a bottom part with an interlocking structure, this utility model improves the stability of the rotating parts. A bevel is provided around the connection between the mounting ring and the top cover. This bevel is in contact with a bevel on the inner side of the mounting hole to increase the contact length between the top cover and the bottom part. At the same time, multiple limiting posts are provided at the lower end of the top cover. A pulley is rotatably provided on the limiting post. The pulley is installed in the slide rail, which increases the stability and service life of the rotating button.
