Description

Torque output adjusting device for calibration of prefabricated torque spanner

Technical Field

The utility model relates to a matched device for calibrating a torque wrench, in particular to a torque output adjusting device for calibrating a prefabricated torque wrench.

Background

The prefabricated torque spanner is a torque spanner with an adjustable set torque value, when the torque spanner is used, the upper limit of a required torque value is set, when the applied torque reaches the set value, the torque spanner can make a click sound, and the click sound represents that the output torque reaches the set torque value, and no force is required to be output.

The existing prefabricated torque wrench 1 is shown in fig. 1, and comprises a wrench body 3 with the length extending along the left-right direction, a torque output head 2 for outputting torque outwards is arranged at the left end of the wrench body 3 in a downward protruding mode, an unlocking sleeve 4 is sleeved at the right end of the wrench body in a guiding and moving mode along the left-right direction, a sleeve reset spring for applying force towards the left direction to the unlocking sleeve is arranged between the unlocking sleeve 4 and the wrench body, an end sleeve 5 is arranged at the right end of the wrench body, a rotating handle 6 with a rotating axis extending along the left-right direction and used for outputting torque adjustment is rotationally assembled at the right end of the wrench body, and a handle arm 6-1 with the length extending along the radial direction of the end sleeve is arranged at the rotating handle.

When the unlocking sleeve is positioned at the locking station which is positioned at the left side under the action of the sleeve reset spring, the rotating handle is locked, and the rotating handle cannot rotate at the moment, so that the output torque of the prefabricated torque spanner cannot be adjusted.
