[0001] This utility model relates to the field of hardness testers, and in particular to a digital display micro Vickers hardness tester with an external protective structure. Background Technology

[0002] The Vickers hardness tester is a high-tech product integrating opto-mechatronics. The machine has a novel design and good reliability, operability and intuitiveness. It is a new type of Vickers and Knoop hardness testing instrument that uses precision mechanical technology and optoelectronic technology. The Vickers hardness tester is mainly used for low-load Vickers hardness testing in materials research and scientific experiments. It can measure the hardness of various metal materials from extremely soft to extremely hard and has a wide range of applications.

[0003] Existing Vickers hardness testers are typically semi-open designs, which means that splashes or fragments generated during the hardness test may cause injury to the operator, posing a certain safety hazard. At the same time, the equipment is more susceptible to external environmental influences, such as dust and moisture, which may affect the accuracy of the test and the lifespan of the equipment.

[0004] Therefore, to address the issue that the splashes or fragments generated during the hardness test may cause injury to operators, and that the equipment is more susceptible to external environmental influences, a digital display micro Vickers hardness tester with an external protective structure can be designed. By installing an external protective structure on the testing part of the Vickers hardness tester and sealing off the testing part, the above problems can be easily solved. Utility Model Content

A hardness testing push rod for pressing the workpiece being tested is installed at the top center of the testing groove. Protective shells for protecting the testing groove are provided on both sides of the testing groove. A digital display stage is provided at the top of the hardness tester body, and a digital display screen is provided at the upper end of the digital display stage. A microscopic observation head is installed at the front end of the digital display stage.

[0007] Preferably, this application combines a hardness tester body, a hardness testing push rod, a digital display stage, a microscopic observation head, and a protective shell. During operation, the operator places the object to be tested in the testing chamber, applies pressure to the object using the hardness testing push rod to perform hardness testing, the protective shell protects the testing area during testing, the digital display stage displays the hardness test data, and the microscopic observation head observes the data.

[0008] Preferably, a support platform is installed at the bottom center of the testing groove, and a lens groove is opened at the lower center of the hardness testing push rod. The lens groove is equipped with a microscope head corresponding to the microscopic observation head.

[0009] Preferably, the top of the testing tank is provided with two sets of support tubes, which are symmetrically arranged on both sides of the hardness testing push rod, and each set of support tubes is provided with a supplementary light tube at its lower end.

[0010] Preferably, the top and bottom of both sides of the rear end of the detection groove are provided with movable holes, and the protective shell includes a fixing frame.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment of a digital display micro Vickers hardness tester with an external protective structure, comprising a base 1, a hardness tester body 2, a hardness detection push rod 4, a digital display stage 5, a microscopic observation head 6, and a protective shell 8; the hardness tester body 2 is provided at the upper end of the base 1, and a detection groove 3 for hardness detection is opened at the front end of the hardness tester body 2. A hardness detection push rod 4 for pressing the workpiece being tested is installed at the top center of the detection groove 3. Protective shells 8 for protecting the detection groove 3 are provided on both sides of the detection groove 3. A digital display stage 5 is provided at the top of the hardness tester body 2, and a digital display screen 7 is provided at the upper end of the digital display stage 5. A microscopic observation head 6 is installed at the front end of the digital display stage 5.

[0022] Please see Figures 1-2In this embodiment, a support platform 10 is installed at the bottom center of the detection groove 3, and a lens groove is opened at the lower center of the hardness detection push rod 4. The lens groove is equipped with a microscope head 9 corresponding to the microscopic observation head 6. The support platform 10 allows the operator to place the item to be tested on the support platform 10 during testing. By combining the microscope head 9 with the microscopic observation head 6, the hardness detection push rod 4 retracts after the hardness pressure is applied, allowing the microscope head 9 to be adjusted to a suitable viewing distance. This facilitates the operator to observe the hardness test marks on the workpiece through the microscopic observation head 6. Two sets of support tubes 11 are provided at the top of the detection groove 3. The two sets of support tubes 11 are symmetrically arranged on both sides of the hardness detection push rod 4. Each set of support tubes 11 has a supplementary light tube 12 at its lower end. By combining the two sets of supplementary light tubes 12, after the microscope head 9 is adjusted to a suitable viewing distance, the two sets of supplementary light tubes 12 provide supplementary light to the workpiece, thereby facilitating the microscope head 9 to capture the texture details of the workpiece.

[0023] Please see Figures 2-3 In this embodiment, a battery slot is provided at the rear end of the digital display platform 5, and a battery pack 14 is provided inside the battery slot. The supplementary light tube 12, the digital display screen 7, and the hardness detection push rod 4 are electrically connected to the battery pack 14. A support frame 15 is provided at the rear end of the digital display screen 7. By combining the battery slot and the battery pack 14, the battery pack 14 can be fixed in the battery slot. The battery pack 14 provides power to the hardness detection push rod 4, the supplementary light tube 12, and the digital display screen 7 so that they can work. Movable holes 13 are provided at the top and bottom of both sides of the rear end of the detection slot 3. The protective shell 8 includes a fixing frame 16. One end of the fixing frame 16 is provided with a movable shaft 19. Both ends of the movable shaft 19 extend into the interior of the movable hole 13. By combining the fixing frame 16 and the movable shaft 19, the operator can rotate the fixing frame 16 along the movable hole 13 through the movable shaft 19 during the test, so that the two sets of protective shells 8 can seal the detection slot 3, thereby preventing the fragments generated when the tested item breaks under force from injuring the operator.

[0024] Please see Figures 3-4In this embodiment, the inside of the fixing frame 16 is provided with a protective plate slot 17, and a transparent resin protective plate 18 is installed inside the protective plate slot 17. By combining the fixing frame 16 with the protective plate slot 17, the transparent resin protective plate 18 can be connected to the fixing frame 16 through the protective plate slot 17. When performing hardness testing, although the protective shell 8 closes the test groove 3, the operator can still observe the condition of the workpiece being tested through the transparent resin protective plate 18. Both sets of protective shells 8 are provided with magnetic strips 20 at their adjacent ends. The magnetic strips 20 are located on the side wall of the fixing frame 16 away from the movable shaft 19. By combining the magnetic strips 20 with the protective shells 8, when the Vickers hardness tester is not in use, the two sets of protective shells 8 close the test groove 3. The magnetic strips 20 connect the ends of the two sets of protective shells 8 away from the movable shaft 19 together, thereby preventing external dust and moisture from entering the interior of the test groove 3 and preventing electronic components such as the microscope head 9 from being corroded by dust and moisture.

[0025] During operation, the staff places the item to be tested on the support platform 10, and then the fixing frame 16 rotates along the movable hole 13 via the movable shaft 19, thereby sealing the testing groove 3 with two sets of protective shells 8, thus preventing the fragments generated when the item being tested breaks under force from injuring the staff.

[0026] Next, the battery pack 14 provides power to the hardness testing push rod 4, which applies pressure to the object being tested to perform hardness testing. After the hardness testing pressure is applied, the hardness testing push rod 4 retracts, allowing the microscope head 9 to be adjusted to a suitable viewing distance. This allows the operator to observe the hardness testing marks on the workpiece through the microscope observation head 6. After the microscope head 9 is adjusted to a suitable viewing distance, two sets of supplementary light tubes 12 provide supplementary lighting to the workpiece being tested, thereby facilitating the microscope head 9 to capture the texture details of the workpiece being tested.

[0027] During hardness testing, although the protective shell 8 seals the testing groove 3, staff can still observe the condition of the workpiece being tested through the transparent resin protective plate 18.

[0028] When the hardness tester is not in use, the two sets of protective shells 8 seal the test groove 3. The ends of the two sets of protective shells 8 away from the movable shaft 19 are attracted together by magnetic strips 20, thereby preventing external dust and moisture from entering the interior of the test groove 3 and preventing electronic components such as the microscope head 9 from being corroded by dust and moisture.

[0029] Through the above steps, this application combines the hardness tester body 2, hardness testing push rod 4, digital display stage 5, microscopic observation head 6, and protective shell 8. During operation, the operator places the object to be tested in the testing groove 3 and applies pressure to the object using the hardness testing push rod 4 to perform hardness testing. During hardness testing, the protective shell 8 protects the testing area, preventing fragments from injuring the operator when the tested object breaks under pressure. When the hardness tester is not in use, the two sets of protective shells 8 seal the testing groove 3. The ends of the two sets of protective shells 8 furthest from the movable shaft 19 are magnetically connected together using magnetic strips 20, thus preventing external dust and moisture from entering the interior of the testing groove 3 and protecting electronic components such as the microscope head 9 from corrosion by dust and moisture.
