A metal hardness tester is mainly used to measure the hardness of metal materials. It can test the performance indicators of metal materials such as wear resistance, pressure resistance and impact resistance. A split hardness tester includes a hardness tester probe structure connected by a wire.

[0003] The existing hardness tester probe structure cannot calibrate the verticality of the overall probe structure, which is prone to skewness and affects the accuracy of detection. Therefore, a hardness tester probe structure with calibrated verticality is proposed to calibrate the verticality of the overall probe structure to avoid skewness and affect the accuracy of detection. Summary of the invention

[0004] In view of the problems in the prior art, the utility model provides a hardness tester probe structure with calibrated verticality, which calibrates the verticality of the overall probe structure to avoid skewness that affects the accuracy of detection.

[0006] An enlarged end plate is welded at equal distances on the outside of the connecting ring, an adjusting screw is installed on the enlarged end plate through a bolt hole, the bottom end of the adjusting screw is connected to an adjusting washer through a bearing, and a level is embedded at one end of the top of the adjusting washer.

[0007] By adopting the above technical solution, the loading sleeve is held and pressed downward to load, and the overall probe structure is placed on the top of the material to be tested. First, observe whether the level bubble in the level is centered. When it is not centered, manually turn the adjustment screws in different directions to adjust the level bubble to the center, so that the adjustment gasket is in a horizontal state, thereby calibrating the verticality of the overall probe structure to avoid skewness and affect the accuracy of the detection. Press the release button to release the impact body in the impact body guide sleeve to complete the detection. When pressing the loading sleeve, the elastic force of the support spring is used to quickly reset the loading sleeve, which is easy to operate and saves manpower and material resources.

[0008] Specifically, the bottom of the loading sleeve and the top of the probe body are respectively sleeved with an enlarged sleeve plate A and an enlarged sleeve plate B.

[0009] Specifically, a support spring is provided between the expansion sleeve A and the expansion sleeve B, and the support spring is sleeved on the outside of the loading rod.

[0010] Specifically, one side of the probe body is connected to an aviation plug via a connecting wire.

[0011] Specifically, a release button is provided on the top of the loading sleeve.

[0012] Specifically, the impact body is sleeved inside the impact body guide sleeve and the impact body passes through the adjusting washer.

[0013] By adopting the above technical solution, the impact body guide sleeve is used to guide the impact body, thereby improving stability.

[0014] Beneficial effects of the utility model:

[0015] The utility model discloses a hardness tester probe structure for calibrating verticality. The loading sleeve is held and pressed downward for loading. The overall probe structure is placed on the top of the material to be tested. First, the level bubble in the level is observed to be centered.
