Abstract

The invention belongs to the technical field of measuring tool reliability, and particularly relates to a steel tape reliability testing device, which solves the problem that an existing reliability testing device cannot carry out reliability tests on a steel tape. The steel tape reliability testing device comprises a supporting frame, a torque detection device, a steel tape unfolding device, a tape drawing device, a steel tape rewinding speed detection device and a console, wherein the supporting frame, the torque detection device, the steel tape unfolding device, the tape drawing device andthe steel tape rewinding speed detection device are all installed on the upper surface of the supporting frame; the steel tape unfolding device is arranged on one side of the torque detection device;the tape drawing device is arranged on the other side of the torque detection device; and the steel tape rewinding speed detection device is arranged on the upper side of the tape drawing device.

Description

technical field [0001] The invention relates to the technical field of measuring tool reliability, in particular to a reliability test device for a steel tape measure. Background technique [0002] In people's daily life or production occasions such as construction, steel tape is widely used. Due to the impact of the use environment and improper operation by the user, the ruler tape will be twisted, broken, rusted or damaged, which will affect people's normal work. It is very important to carry out the reliability test on the steel tape and obtain its reliability test data to provide the basis for the reliability improvement design of the steel tape. At present, the reliability test of the steel tape is usually an on-site reliability test, and there is almost no reliability test device for the steel tape in China. In view of the above problems, the present invention provides a steel tape measure reliability test device. Contents of the invention [0003] The technical p...
