Technical Field
[0001] The utility model belongs to the technical field of steel structure detection, and particularly relates to a multifunctional Leeb hardness tester. Background Art
[0002] The Leeb hardness tester is a kind of testing equipment. With the development of monolithic technology, its basic principle is that an impact body with a certain mass impacts the sample surface under a certain test force, and the impact velocity and rebound velocity of the impact body at a distance of 1mm from the sample surface are measured. Using the electromagnetic principle, a voltage proportional to the velocity is induced.
[0003] The test data of the existing Leeb hardness tester equipment needs to be recorded manually, and both hands are needed to operate it during the test. It is inconvenient to hold the hardness tester with both hands when working at heights, and workers are prone to mistakes, causing the equipment to fall off, which in turn causes equipment damage. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a multifunctional Leeb hardness tester, comprising: a hardness tester body, a conductive line, an elastic hammer and a bracket, wherein the hardness tester body is movably connected to the elastic hammer through the conductive line;
[0006] The elastic hammer includes a measuring rod and a connector, one end of the conductive wire is fixedly connected to the top of the hardness tester body, and the other end of the conductive wire is fixedly connected to the connector;
[0007] The middle part of the hardness tester body is rotatably connected to the bracket, the bracket is arranged on the outside of the hardness tester body, and a magnet is arranged inside the bracket;
[0008] One end of the bracket is connected to a rotating shaft, the rotating shaft is arranged inside the hardness tester body, and the rotating shaft passes through both sides of the hardness tester body;
[0009] A data module is provided inside the hardness tester body.
[0010] Furthermore, a display screen is provided on one end of the hardness tester body close to the conducting wire.
[0011] Furthermore, a plurality of buttons are provided in the middle of the hardness tester body.
[0012] Furthermore, a guide outlet is provided on one end of the hardness tester body away from the conductive wire.
[0013] Furthermore, the angle between the bracket and the hardness tester body is 0°~90°.
[0014] Furthermore, the hardness tester body, the conductive wire and the elastic hammer are all electrically connected.
[0015] The beneficial effects of the utility model are:
[0016] 1. Set up the bracket. When working at height, open the bracket and rotate it to the maximum angle. There is a magnet inside the bracket, which can be used to magnetically attract the bracket to a nearby steel plate. Then use a spring hammer to measure the hardness of the steel to avoid equipment falling and damage due to improper operation.
[0017] 2. By setting the data module, the elastic hammer transmits the hardness of the steel to the hardness tester through the conductive line. The data module automatically stores and records the data, and can infer the minimum and maximum tensile strength of the steel according to the existing standard curve, and can form a document in a fixed format. Then, the data can be exported to the computer via a data cable to avoid errors caused by manual on-site data inference.

[0027] Example:
[0028] like Figure 1 As shown, a multifunctional Leeb hardness tester includes: a hardness tester body 1, a conductive line 2, an elastic hammer 3 and a bracket 4. The hardness tester body 1 is movably connected to the elastic hammer 3 through the conductive line 2.
[0029] Among them, the elastic hammer 3 includes a measuring rod 31 and a connecting head 32. One end of the conductive wire 2 is fixedly connected to the top of the hardness tester body 1, and the other end of the conductive wire 2 is fixedly connected to the connecting head 32. The measuring rod 31 is used to measure the hardness of the steel, and the connecting head 32 is used to bear force. After the connecting head 32 is subjected to force, the measuring rod 31 measures the hardness of the steel and transmits the data to the hardness tester body 1 through the conductive wire 2.
[0030] The middle part of the hardness tester body 1 is rotatably connected to a bracket 4, which is arranged on the outside of the hardness tester body 1. A magnet is arranged inside the bracket 4. The hardness tester body 1 can be adsorbed on the steel plate through the magnet of the bracket 4, which is convenient for workers to perform subsequent operations; one end of the bracket 4 is connected to a rotating shaft, which is arranged inside the hardness tester body 1 and passes through both sides of the hardness tester body 1. The angle between the bracket 4 and the hardness tester body 1 is 0°~90°. The bracket 4 rotates relative to the hardness tester body 1 through the rotating shaft. The maximum rotation angle of the bracket 4 is 90°. When working at high altitude, the bracket 4 is rotated to the maximum angle and then magnetically attracted to the steel plate.
[0031] A data module is provided inside the hardness tester body 1. The steel hardness data measured by the elastic hammer 3 is transmitted to the data module. The data module automatically stores and records the data, and can infer the minimum and maximum tensile strength of the steel based on the existing standard curve. It can also form a document in a fixed format and then export the data by connecting to a computer via a data cable, avoiding errors caused by manual on-site data inference.
[0032] A display screen 11 is provided on the end of the hardness tester body 1 close to the conductive wire 2; a plurality of buttons 12 are provided in the middle of the hardness tester body 1; and an output port 13 is provided on the end of the hardness tester body 1 away from the conductive wire 2. The hardness tester body 1, the conductive wire 2, and the elastic hammer 3 are all electrically connected, and the steel hardness file formed by the data module is exported through the output port 13, thereby improving the efficiency of data recording and replacing the time spent on manual data recording.
[0033] To sum up, when working at height, rotate the bracket 4 to the maximum angle, magnetically attract the bracket 4 to the steel plate, and then fix the hardness tester body 1 on the steel plate. The steel hardness data is measured by the elastic hammer 3. The elastic hammer 3 transmits the measured steel hardness data to the data module through the conductive line 2. The data module automatically stores and records the data, and can infer the minimum and maximum tensile strength of the steel based on the existing standard curve to form a document in a fixed format. Then, connect the computer through the data cable to export the data from the export port 13. After the measurement is completed, remove the hardness tester body 1 and rotate the bracket 4 to retract the hardness tester body 1.
