Therefore, a building material hardness testing device is proposed. Utility Model Content

[0004] Furthermore, the protection mechanism includes a pressure cylinder, the output shaft piston cylinder of the pressure output mechanism is connected to the interior of the pressure cylinder, and also includes a hydraulic sensor fixed inside the top of the machine, the pressure probe of the hydraulic sensor passes through the outer wall of the pressure cylinder and is inserted into the interior of the pressure cylinder, and the interior of the pressure cylinder is filled with hydraulic oil.

[0007] Furthermore, the sealing ring is a rubber sealing ring. Beneficial Effects
[0008] When testing the hardness of building materials, the building materials are placed on a placement table, the pressure head is installed on the protection mechanism, and the display controller is started to extend the output shaft of the pressure output mechanism downward, so that the pressure head is pressed downward to test the building materials. At the same time, when the downward pressure is greater than or equal to the pressure that the pressure head can withstand, the protection mechanism feeds back the pressure information to the display controller, and the pressure output mechanism is stopped through the display controller, thereby protecting the pressure head.
[0009] When protecting the pressure head, the output shaft of the pressure output mechanism extends downward, so that the output shaft of the pressure output mechanism presses the hydraulic oil inside the pressure cylinder downward, and the hydraulic sensor monitors the pressure of the hydraulic oil inside the pressure cylinder. The hydraulic sensor feeds back the monitored pressure data to the display controller. However, when the pressure is greater than the pressure that the pressure head can withstand, the pressure output mechanism is stopped through the display controller, thereby achieving protection of the pressure head.
[0010] When the pressure head is quickly disassembled, the display controller is used to control the telescopic end of the electric push rod to extend, so that the telescopic end of the electric push rod moves downward inside the piston cylinder, so that the air inside the piston cylinder is sent into the interior of the mounting hole through the air guide pipe, and under the action of atmospheric pressure, the pressure head is pushed out from the interior of the mounting hole to complete the disassembly.
[0011] During quick installation, the top of the pressure head is inserted into the mounting hole, and the telescopic end of the electric push rod is controlled to retract through the display controller, so that the telescopic end of the electric push rod moves upward inside the piston cylinder, and the piston cylinder draws the gas inside the mounting hole into the piston cylinder through the air guide pipe, so that the pressure head is installed and fixed to the mounting hole under the action of atmospheric pressure.
