AI Technical Summary

Technical Problem

Existing electrical safety testing equipment cannot enter confined spaces, limiting its scope of use and requiring two people to operate it.

Method used

The detection probe is fixed by a clamp and its position is locked by a locking assembly, so that the detection probe is in contact with the object to be tested. This frees up the worker's hands to operate the multimeter. The two test heads are set independently, which makes it easy to enter confined spaces.

Benefits of technology

It enables a single person to complete electrical safety testing, expands the scope of application of the equipment, and saves manpower.

Abstract

This utility model belongs to the field of devices for testing electrical performance, and particularly relates to an electrical safety testing device. To broaden its applicability, this utility model proposes an electrical safety testing device. The electrical safety testing device includes a multimeter and two test heads, as well as two clamps for holding the object under test. Each test head includes a test probe electrically connected to the multimeter via a wire, a cylinder fitted over the test probe and fixedly connected to different clamps, a push rod with one end extending into the cylinder for pushing the test probe out of the cylinder to contact the object under test during measurement, and a locking assembly for locking the push rod. A through hole is provided on the side wall of the cylinder. The locking assembly includes a locking rod, a locking element, and a reset elastic element. The locking rod passes through the through hole, the locking element is located inside the cylinder and connected to the locking rod, and the push rod has a locking part that matches the locking element. The two test heads are independently set up, facilitating their entry into confined spaces and thus broadening their applicability.
