Description

Technical Field

[0001] This utility model relates to the technical field of portable resistance tester devices, and in particular to a portable resistance tester device. Background Technology

[0002] In modern industrial production, scientific research experiments, and the maintenance of various electrical equipment, accurate measurement of resistance values ​​is a crucial link in ensuring stable system operation, guaranteeing product quality, and advancing research progress. As the core equipment for accurately acquiring resistance data, the importance of resistance testers is self-evident. However, traditional resistance testers have gradually revealed many limitations in practical applications, prompting the research and development and improvement of portable resistance tester devices. At the same time, with the continuous advancement of technology and the ever-increasing demand for resistance testing in various industries, it is urgent to develop a portable resistance tester device that integrates high portability, good protection, and convenient access. This will not only meet the resistance testing needs of different industries in complex and diverse environments, but will also promote a qualitative improvement in work efficiency and quality in related fields.

[0003] A search revealed Chinese Patent Publication No. CN220367349U, which discloses a resistance tester. The tester includes a main body with an operation panel fixed to its front and a mounting frame fixed to its top. A handle is hinged to the inner side of the mounting frame, and a cover plate is slidably connected inside the mounting frame. The mounting frame also has a sliding groove. This invention uses a mounting frame and cover plate to securely store the handle, while a separate support leg not only supports the device but also provides insulation. The mounting frame and support leg effectively prevent dust and dirt from the construction site from contaminating the handle and the bottom of the tester, facilitating use in various environments and solving the problems of existing resistance testers. The handle and bottom of the testing instrument are easily soiled by dust and sewage at construction sites, making it inconvenient to use in dirty environments. While the aforementioned devices are large and complex benchtop equipment, and while they offer advantages in measurement accuracy and functional completeness, their heavy weight and fixed usage scenarios severely limit their application scope. For example, in the power industry, when performing resistance testing on widely distributed transmission lines and substation equipment, technicians must transport the entire set of equipment to the site, a time-consuming and labor-intensive process. Furthermore, in areas with complex terrain and limited space, large equipment is simply unusable. In addition, the difficulty of transporting traditional testing instruments when researchers are conducting field research and moving between different laboratories greatly hinders the continuity and efficiency of research. Utility Model Content
