A mechanical release digital display torque wrench

Abstract

The invention discloses a mechanical tripping type digital display torque wrench, which comprises a ratchet head, a stress application rod, a sensor, a display controller, a pressure regulator and a mechanical latching compartment, wherein the sensor is arranged in the stress application rod, and is connected with the ratchet head and the display controller; the display controller is connected with the pressure regulator; a regulation ring is arranged at the bottom of the pressure regulator; the mechanical latching compartment is formed in the middle of the stress application rod, and comprises a mechanical lock, a mechanical buckle, a mechanical button and a propeller; the mechanical lock is mechanically buckled on the mechanical button; the mechanical button is clamped between the mechanical lock and the propeller. According to the mechanical tripping type digital display torque wrench adopting the technical scheme, measurement accuracy is ensured, and a stress source can be accurately and automatically disconnected; the torque wrench is simple in structural design, high in accuracy and measurement accuracy and easy and convenient to operate, and comprises few parts, factors causing errors are small, and high-quality, intelligent and digital functions are really realized.

Description

technical field [0001] The invention relates to a wrench, in particular to a mechanical release digital display torque wrench. Background technique [0002] Torque wrench, a traditional hand hardware tool used for loading and unloading fasteners, is constantly changing with the continuous development and demand of science and technology. From the first generation single-function tightening torque wrench to the second generation wrench with fixed torque and adjustable force measurement type manufactured by using the mechanical characteristics of the spring, these are all controlled by mechanical pointer and disconnection. , it needs to be corrected frequently in use, and the error is large. The third generation is the electronic display type, which adopts the sensor conversion technology, and directly sends it to the display through the amplifier, so the precision is low, it has no control function, and it cannot maintain the peak value. The fourth generation is further imp...

From the first generation single-function tightening torque wrench to the second generation wrench with fixed torque and adjustable force measurement type manufactured by using the mechanical characteristics of the spring, these are all controlled by mechanical pointer and disconnection. , it needs to be corrected frequently in use, and the error is large

The third generation is the electronic display type, which adopts the sensor conversion technology, and directly sends it to the display through the amplifier, so the precision is low, it has no control function, and the peak value cannot be maintained.

Its structure is complicated, the setting is cumbersome, the measurement accuracy is low (2% accuracy), and the service life is short
