Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hardness detectors, in particular to a material hardness detector. Background Technique
[0002] A hardness tester is a hardness testing instrument. The measurement of metal hardness was first proposed by Réaumur to define hardness, indicating the ability of a material to resist the penetration of a hard object into its surface. It is one of the important performance indicators of metal materials. Generally, the higher the hardness, the better the wear resistance.
[0003] When the current hardness tester is performing a hardness test on a material, when the surface to be measured of the material is an inclined plane, a deflecting force will be generated when the indenter contacts the material, which is likely to cause the material to displace, affecting the progress of the hardness test, and on the other hand, it is likely to cause damage to the indenter.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-4As shown in the figure, a material hardness detector includes a detector body 1. At the top of the inner cavity of the detector body 1, there is a detection head 15. At the top of the inner cavity of the detector body 1, there is an upgrade mechanism 2. At the top of the upgrade mechanism 2, there is a fixed block 3. Inside the fixed block 3, there is a rotatable movable block 16. At the top of the movable block 16, there is a fixedly connected detection table 4. On the surface of the fixed block 3, there is a fixed plate 5. Inside the fixed plate 5, there is a screw rod 6 threadedly connected. At the bottom end of the screw rod 6, there is a fixedly connected torsion disc 7. The top of the screw rod 6 is hinged to the bottom of the detection table 4. On both sides of the surface of the detector body 1, there are fixed folding plates 9. And between the left and right folding plates 9, there is a fixed rod 10. On the surface of the fixed rod 10, there is a movable slider 11. On the surface of the detector body 1, there is an activity groove 17. The back of the slider 11 is movably connected to the surface of the activity groove 17. In this way, the slider 11 can be assisted in being limited, facilitating its left and right movement. At the front end of the slider 11, there is a cleaning plate 12. At the bottom of the cleaning plate 12, there are a number of bristles, and the bristles are flush with the top surface of the detection table 4. In this way, as the cleaning plate 12 moves, the top surface of the detection table 4 can be cleaned, facilitating subsequent material detection.
[0023] At the back of the fixed block 3, there is a hinged telescopic rod 8. The other end of the telescopic rod 8 is hinged to the bottom of the detection table 4. In this way, the detection table 4 can be assisted in being supported, facilitating the stable tilting and deflection of the detection table 4.
[0024] Above and below both sides of the slider 11, there are fixed iron sheets 14. Above and below the inner side of the folding plate 9, there are fixed magnets 13. In this way, when the cleaning plate 12 is not in use, the slider 11 will be fixed in fit with the inner wall of the folding plate 9 through the cooperation between the iron sheet 14 and the magnet 13, thereby preventing its random movement.
[0025] At the bottom right of the detector body 1, there is a power socket 18. And inside the power socket 18, there is a plugged-in power supply socket 19. In this way, after the power supply socket 19 is powered on, the detector body 1 can work normally, facilitating the testing of the hardness of products.
[0026] It should be noted that: in this technical solution, technical features such as etc. should be regarded as prior art. For the specific structures, working principles, and possible control methods and spatial layout methods involved in these technical features, the conventional selections in the field can be adopted, and this technical solution will not be further specifically elaborated.
[0027] Working principle: When in use, according to the style of the product, then rotate the turntable 7, which drives the screw rod 6 to rotate, and at the same time drives the inspection table 4 to deflect at an angle. After deflecting to a certain angle, the product can be placed on the top of the inspection table 4. Then, the hardness of the material can be detected by the detection head 15. After the detection is completed, for the convenience of subsequent detection, the cleaning plate 12 can be driven to move to the left, so that the cleaning plate 12 can clean the surface of the top of the inspection table 4, and then better detect the hardness of the material subsequently.
