[0002] A sensor is a detection device that can sense the information being measured and can convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. For example, laser distance sensors are widely used in construction and other industries due to their convenient and fast measurement, high accuracy and large range. In order to ensure the accuracy of the laser distance sensor, it is usually necessary to test it so that it can be calibrated after the deviation is found. However, most of the existing testing methods are that the staff uses the laser distance sensor to directly measure the distance between two walls or objects, and then uses other measurement tools for measurement comparison. Because it is in a temporary manual measurement environment, it is difficult to ensure the accuracy of the measurement data, and it is not conducive to subsequent unified and standardized testing.

DETAILED DESCRIPTION
[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0020] like Figure 1-Figure 4 As shown, a sensor testing device that is easy to assemble includes a first test bench 1 and a second test bench 2. The first test bench 1 is provided with a first slot 3 near the left and right ends and in the middle of the second test bench 2. A detachable starting plate 4 is inserted into the first slot 3 at the left end of the first test bench 1, and a detachable concave plug-in 9 is inserted into the first slot 3 on the second test bench 2. Three groups of slide grooves 10 are provided inside the concave plug-in 9. A ranging plate 11 is slidably installed inside the slide groove 10 on the left side, and a glass plate 12 is slidably installed inside the middle slide groove 10. The first test bench 1 is provided with a through slot 14 near the front and rear sides, and a connecting rod 15 is slidably installed inside the through slot 14 near the right side, and the right end of the connecting rod 15 passes through and is slidably connected to the inside of the second test bench 2.
[0021] A spirit level 5 is fixedly installed on the left end of the starting plate 4 near the middle of the lower side. The upper ends of the first test bench 1 and the second test bench 2 are fixedly connected with threaded barrels 6 at two far-away corners. The interiors of the threaded barrels 6 are threadedly connected with threaded rods 7. The lower ends of the threaded rods 7 respectively penetrate the first test bench 1 and the second test bench 2 and are fixedly connected with universal wheels 8. The horizontal position of the device can be detected by the spirit level 5. When a tilt occurs, due to the design of the threaded barrel 6, the universal wheel 8 can be driven to rise and fall by rotating the threaded rod 7, thereby achieving the purpose of adjusting the height, ensuring that the device is on a horizontal plane during testing and ensuring the accuracy of the test data.
[0022] A plurality of assembly plates 16 are arranged between the first test bench 1 and the second test bench 2. Semicircular grooves 17 are arranged at the lower ends of the assembly plates 16 near the front and rear sides. The semicircular grooves 17 are matched with the connecting rods 15. The assembly plates 16 are continuously arranged at the upper ends of the connecting rods 15 through the semicircular grooves 17. A second slot 18 is arranged at the middle of the upper band of the assembly plates 16. The second slot 18 has the same size as the first slot 3. The technical scheme firstly takes the right end face of the starting plate 4 as the starting measurement position, and the corresponding positions on the second test bench 2 and the assembly plate 16 are engraved with length units by high-precision instruments, so that the measurement data of the laser ranging sensor body 20 can be tested and compared, and the concave plug-in 9 is placed in the first slot 3 and the second slot 18 at different positions respectively, so as to perform multiple tests. When the multiple measurement data are consistent with the scale value, it is more representative.
[0023] The front and rear ends of the concave plug-in 9 are fixedly connected to the limiting member 13 near the lower side, and the lower end of the limiting member 13 is in contact with the second test bench 2. The limiting member 13 supports the concave plug-in 9 to facilitate the replacement of different test points.
[0024] A hidden groove 19 is provided near the middle of the upper end of the first test bench 1, and the hidden groove 19 is adapted to the concave plug-in 9. Two groups of laser ranging sensor bodies 20 are placed at the right end of the upper end of the first test bench 1 where the starting point plate 4 is fitted. After the test is completed, the concave plug-in 9, the ranging plate 11 and the glass plate 12 can be placed therein through the hidden groove 19, and the starting point plate 4 and the assembly plate 16 can be removed and stacked on the combination of the first test bench 1 and the second test bench 2. At the same time, the connecting rod 15 continues to be inserted into the through groove 14, so that the first test bench 1 and the second test bench 2 can be fitted together in the end, which provides stable support while greatly reducing the space occupied. The device can be moved by the universal wheel 8, so that it is convenient to store it in a relatively narrow space and take it out when in use. The assembly is similar, which is very simple and convenient.
[0025] Working principle:
[0026] When in use, in order to facilitate users to find the measuring point more easily during use, the shell of the laser distance measuring sensor body 20 is usually made into a flat cube shape, so that when testing, the laser distance measuring sensor body 20 can be directly placed on the upper end of the first test bench 1, so that its rear end is close to the right end face of the starting plate 4, and the starting position of the measurement is solidified, which is convenient for subsequent data comparison. At the same time, the laser distance measuring sensor body 20 can be placed straight to avoid skewing. By opening the laser distance measuring sensor body 20, it can be irradiated on the distance measuring board 11. The technical solution first uses the right end face of the starting plate 4 as the starting point. The corresponding positions on the second test bench 2 and the assembly plate 16 are engraved with length units by high-precision instruments, so that the measurement data of the laser ranging sensor body 20 can be tested and compared. By placing the concave plug-in 9 in the first slot 3 and the second slot 18 at different positions, multiple tests can be performed. When the multiple measurement data are consistent with the scale value, it is more representative. Furthermore, by pulling the ranging plate 11 out of the slide slot 10 and inserting it into the slide slot 10 on the right side of the glass plate 12, it is tested whether there is a deviation when the laser ranging sensor body 20 passes through a transparent object. Compared with the traditional test method, the use of the present device is not only convenient to operate, but also, through the prefabricated high-precision scale, there is no need for the staff to temporarily use other measuring tools for measurement, and the accuracy of the test results is guaranteed. The multi-point comparison also makes the test data more universal. In addition, the horizontal position of the present device can be detected by the level meter 5. When a tilt occurs, due to the design of the threaded cylinder 6, the universal wheel 8 can be driven to rise and fall by rotating the threaded rod 7, thereby achieving the purpose of adjusting the height, ensuring that the present device is on a horizontal plane during the test, and ensuring the accuracy of the test data. In addition, After the test is completed, the concave plug-in 9, the distance measuring plate 11 and the glass plate 12 can be placed in the hidden groove 19, and the starting plate 4 and the assembly plate 16 can be removed and stacked on the combination of the first test bench 1 and the second test bench 2. At the same time, the connecting rod 15 continues to be inserted into the through groove 14, so that the first test bench 1 and the second test bench 2 can be fitted together, which not only provides stable support, but also greatly reduces the space occupied. The universal wheel 8 can make the device movable, so that it is convenient to store in a relatively small space and take it out when in use. The assembly is similar, which is very simple and convenient.
