Description

Technical Field

[0001] This application relates to the technical field of building material quality testing equipment, specifically a hardness tester. Background Technology

[0002] With the development of the construction industry, the quality control of building materials has become increasingly important. Hardness, as one of the key indicators for measuring material performance, has received widespread attention. A hardness tester is a hardness testing instrument. The definition of hardness was first proposed by Leo Muller, representing a material's ability to resist indentation. It is one of the important performance indicators of metallic materials. Generally, the higher the hardness, the better the wear resistance. Hardness testers can be classified according to their operating principle into Leeb hardness testers, Rockwell hardness testers, Brinell hardness testers, Shore hardness testers, Barcol hardness testers, microhardness testers, Mohs hardness testers, Vickers hardness testers, etc.

[0003] However, existing hardness testers require two hands to operate, with one hand holding the tester and the other holding the testing rod for measurement. When working at heights, workers need to use both hands, making it difficult to maintain balance and increasing the risk of falling. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a hardness tester that allows for hardness testing with just one hand holding the handle, thereby increasing safety during high-altitude operations and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a hardness tester, comprising a bracket, a handle fixedly connected to one side of the bracket, a rubber anti-slip pad fixedly connected to the outer surface of the handle, an elastic wristband fixedly connected to the end of the handle away from the outer surface of the bracket, a limiting component provided above the bracket, a hardness tester body provided above the bracket, two sets of symmetrical first mounting blocks fixedly connected to the bottom surface of the hardness tester body, a lead screw slidably connected to the inner wall of the bracket, a locking component provided at one end of the lead screw, a test rod provided on the outside of the hardness tester body, a second mounting block fixedly connected to the outer surface of the test rod, a data cable fixedly connected to one end of the test rod, a connector fixedly connected to the end of the data cable away from the test rod, and the hardness tester body fixedly connected to the connector.

[0006] Through the above scheme, through the setting of the limiting assembly and the first mounting block, the hardness detector body and the support can be quickly connected, and then the test rod and the screw rod can be quickly connected and locked through the locking assembly. At this time, the worker can hold the handle with one hand to monitor the hardness of the target, thereby reducing the necessity of two-handed operation during high-altitude work, effectively improving the balance stability of the worker, reducing the risk of falling and improving safety. And under the action of the elastic wrist strap, the support can be hung on the wrist, thereby avoiding the device from falling and reducing the risk of high-altitude falling.

[0007] Further, the inner wall of the inner threaded handle is threadedly connected to the outer surface of the screw rod.

[0008] Through the above scheme, through the setting of the screw rod and the inner threaded handle, rotating the inner threaded handle can adjust the length of the screw rod and the position of the test rod, thereby adapting to the measurement requirements of different heights and distances.

[0009] Further, the inner wall of the support is fixedly connected with a limiting block, and the outer surface of the screw rod is provided with a limiting groove, and the limiting block is slidably arranged in the inner wall of the limiting groove.

[0010] Through the above scheme, the limiting groove cooperates with the limiting block to limit the movement of the screw rod, thereby preventing the screw rod from rotating with the inner threaded handle when the inner threaded handle is rotated, and preventing the screw rod from being unable to adjust.

[0011] Further, the limiting assembly comprises two limiting boxes fixedly connected to the upper surface of the support, the inner walls of the two limiting boxes are slidably connected with two symmetric moving blocks, the side surfaces of the two moving blocks away from each other are fixedly connected with limiting insertion rods, the outer surfaces of the limiting insertion rods are inserted into the inner walls of the first mounting blocks, and the side surfaces of the two moving blocks close to each other are fixedly connected with first springs.

[0012] Through the above scheme, through the setting of the first spring and the limiting insertion rod, the first spring drives the limiting insertion rod to insert into the inner wall of the first mounting block, thereby limiting the hardness detector body, ensuring the stability of the hardness detector body on the support, and the limiting assembly can quickly disassemble the hardness detector body, thereby facilitating the maintenance of the hardness detector body.

[0013] Further, two symmetric connecting rods are arranged between the two limiting boxes, the two ends of the two connecting rods are fixedly connected to the moving blocks inside the two limiting boxes, and the upper surfaces of the two limiting boxes are fixedly connected with rubber pads.

[0014] Through the above scheme, through the action of the connecting rod, the worker can move the two connecting rods inward, that is, the limiting plug rod is separated from the inside of the first mounting block, which is simple and convenient to operate, improves the operation convenience, and the rubber pad can protect the hardness detector body above, avoid the impact between the limiting box and the hardness detector body due to vibration, improve the protection.

[0015] Further, the locking assembly comprises a placing seat fixedly connected to one end of the lead screw, the outer surface of the placing seat is provided with a placing groove, and the inner wall of the placing groove is provided with a insertion slot, and the outer surface of the second mounting block is inserted into the inner wall of the insertion slot.

[0016] Through the above scheme, through the action of the insertion slot and the second mounting block, the test rod installation can be positioned, so as to quickly install the test rod in the inside of the placing groove.

[0017] Further, the inner wall of the placing seat is slidably connected with a moving plate, the bottom surface of the moving plate is fixedly connected with a special-shaped plug, the side surface of the special-shaped plug close to the inner wall of the placing groove is a slope, the outer surface of the special-shaped plug is inserted into the inner wall of the second mounting block, and the upper surface of the moving plate is fixedly connected with two second springs, and one end of the second spring away from the upper surface of the moving plate is fixedly connected with the inner wall of the placing seat.

[0018] Through the above scheme, the side surface of the special-shaped plug is a slope, which makes the installation of the test rod more convenient, and then the special-shaped plug can be inserted into the inner wall of the second mounting block under the pushing of the second spring, so as to limit the test rod, thereby ensuring the stable detection of the test rod and avoiding falling during detection.

[0019] Further, the upper surface of the moving plate is fixedly connected with a connecting column, and one end of the connecting column extends to the outside through the inner wall of the placing seat, and the end of the connecting column away from the upper surface of the moving plate is fixedly connected with a pulling block.

[0020] Through the above scheme, through the action of the pulling block, the pulling block is located above the placing seat, so that the worker can quickly release the limitation of the test rod, and improve the operation convenience of the device.
