Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a comprehensive hardness measuring instrument for building inspection, so as to solve the problem in the prior art that when the hardness inspection of the metal steel sheet is performed, the device is manually pressed down. The strength of the process is difficult to grasp, resulting in a large force when the metal steel sheet is pressed, resulting in relatively deep indentations on the surface of the metal steel sheet. Dust particles are easy to fly directly to the surface of the metal steel sheet to be tested, so that when the pressed piece is in contact with the metal steel sheet, due to the interaction between the force and the dust particles, it is easy to cause the steel sheet to be affected by the force during the measurement. And slipping, there is a displacement phenomenon, which leads to the defect that the measured results are scattered in many ways and the results are inaccurate

Abstract

The invention discloses a comprehensive hardness measuring instrument for building inspection, which comprises a main body, an eyepiece, an indenter, a support frame, a workbench, a touch screen and a hand crank. Beneficial effects: the invention utilizes the anti-movement structure to realize that the user can effectively hinder the strength of the detection object at a certain height while the user is detecting the detection object by pressing down the pressure head, so as to prevent the user from using excessive force. , resulting in relatively deep indentations on the surface of the test object due to the large force, which makes the measurement results in many ways inaccurate, and the interaction between the dust suction mechanism and the anti-movement structure and the adsorption of the airflow With the cooperation of the friction strip, it can effectively avoid the phenomenon of displacement and slipping of the detection object under the force of the pressure head. At the same time, under the action of the electrostatic column, the dust particles around the detection object are electronically adsorbed, so that they are concentrated on the dust collector. The ring surface avoids measurement structure errors due to the interaction of dust particles with forces.

Description

technical field [0001] The invention relates to the technical field of hardness detection, more precisely, it relates to a comprehensive hardness measuring instrument for building detection. Background technique [0002] During construction, in order to ensure the quality and safety of construction projects and prevent them from collapsing after a period of use and causing serious harm to residents, people have switched from the previous stone slab buildings to today's steel structure buildings. The steel structure building adopts the mutual combination of concrete and steel structure frame, so when it collapses in the event of natural disasters, it can effectively reduce its harm to people, so the construction party uses steel materials in order to ensure its Safety and quality require hardness testing of steel materials in order to be put into use. However, when using comprehensive hardness measuring instruments for building testing, they have the following defects: when t...
