Description

Technical Field

[0001] This utility model relates to the field of torque sensor technology, and in particular to a portable torque sensor. Background Technology

[0002] Torque measurement plays a crucial role in various fields, including industrial production, equipment maintenance, and mechanical research. Traditional torque sensors, due to their large size and heavy weight, have significant limitations in their application scenarios. In industrial settings, the installation, commissioning, and maintenance of equipment often require technicians to carry sensors, including torque sensors, between different work areas.

[0003] Currently, most existing torque sensors achieve their effects using the following technologies;

[0004] Strain gauge technology involves attaching strain gauges to an elastic shaft. When the elastic shaft is subjected to torque, it will produce minute deformations, and the resistance value of the strain gauges will change accordingly. The magnitude of the torque can be calculated by measuring the change in resistance value.

[0005] Magnetoelectric technology uses changes in the magnetic reluctance of a magnetic circuit to measure torque;

[0006] Photoelectric technology uses photoelectric elements to convert torque signals into light signals for measurement.

[0007] Ultrasonic technology uses the propagation characteristics of ultrasonic waves in an elastic shaft to measure torque.

[0008] Currently, existing torque sensors have been found to have at least the following technical problems in practical use;

[0009] Most existing torque sensors only have a torque sensor body and lack a structure for easy transport under force. When transporting the torque sensor, an additional loading mechanism is required. Furthermore, when using the torque sensor, it also needs to be used with additional power supply, electronic control, and display mechanisms for users to observe torque values. In addition, transporting these auxiliary mechanisms is quite troublesome, which greatly affects portability. Therefore, most existing torque sensors have the problem of low portability.
