Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a material hardness detection device for construction engineering. Background Art

[0002] One type of hardness test is the Rockwell test, which works by placing a steel ball on a flat object to be tested, applying a preset test force to it, and measuring the diameter of the indentation that appears on the surface to be tested to determine the hardness of the material to be tested.

[0003] According to the "A material hardness testing equipment for construction projects (Announcement No.: CN 218382014U; Application No.: 202222432904.4)" published on the patent website, the above application optimizes the problem that "the loading pressure head and the test diameter need to be measured separately, which wastes time when testing a large number of materials." However, when the testing device in the above application is in use, it is the same as the existing equipment. The staff are unable to quickly complete the replacement of the steel ball. When in use, the steel ball is directly squeezed into contact with the material under long-term force. After long-term use, the bottom is prone to deformation and needs to be replaced regularly. If it cannot be replaced quickly, a lot of time will be spent on the replacement operation, which slows down the overall work efficiency of the device. Utility Model Content
