[0031] The height adjusting component 4 includes a sliding shaft 41 and a threaded adjusting rod 42. The threaded adjusting rod 42 is composed of a first threaded rod 43 and a second threaded rod 44 which are rotationally connected. The sliding shaft 41 and the threaded adjusting rod 42 are respectively installed at two corners on one side of the upper end of the bottom plate 1;

[0032] The test plate fixing structure 2 includes two sliding plates 21. The two sliding plates 21 are respectively sleeved on the outer surfaces of two groups of the first threaded rods 43 and the sliding shaft 41. Sliding rails 22 are arranged at both ends of one side of the sliding plate 21 facing the middle of the bottom plate 1. A locking structure 23 is arranged inside the sliding rail 22;

[0033] The testing structure includes two adjusting plates 31. The two adjusting plates 31 are respectively sleeved on the outer surfaces of two groups of the second threaded rods 44 and the sliding shaft 41. An installation rack 32 is rotatably arranged on one side of the two adjusting plates 31 facing each other. A detection module 33 is arranged inside the installation rack 32.

[0034] In this embodiment, during use, the coating to be tested is applied to the surface of the test plate. After the coating dries, the test plate is installed on the upper end of the test plate fixing structure 2, and the side coated with the coating to be tested faces the testing structure 3. The test plate fixing structure 2 and the testing structure 3 are respectively adjusted through the height adjusting component 4 so as to achieve experiments on different strengths and data of the coating layer;

[0035] Specifically, after the test plate is installed, by adjusting the height of the testing structure, the testing structure is made parallel to the test plate, and the detection module 33 is made to contact the coating layer and slide on the surface of the coating layer. The friction force on the surface of the coating layer is measured by the detection module 33 rubbing on the surface of the coating layer;

[0036] Further, the test plate is adjusted to a certain angle, and the height of the testing structure is adjusted so that the bottom end of the detection module 33 contacts the lower side of the inclined surface of the test plate. When the detection module 33 moves, the pressure in contact with the test plate will gradually increase, so as to achieve the purpose of testing the wear resistance and pressure resistance of the coating layer;

[0037] Further, by replacing the detection module 33 with a camera, and raising the height of the detection module 33 before installing the camera to avoid the camera contacting the coating layer, the texture, smoothness and fineness of the surface of the coating layer are recorded by the camera, so as to facilitate data and appearance comparison when testing another coating.

By rotating the clamping screw 25, the clamping member 26 on the side of the clamping screw 25 is brought into contact with the side wall of the test plate, achieving the effect of fixing the test plate. And through the setting of the sliding rail 22, when adjusting the angle inclination of the test plate, the relative position of the test plate and the sliding plate 21 can be changed by the movement of the sliding block 24 inside the sliding rail 22, so as to facilitate the angle adjustment of the test plate.

[0040] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, the clamping member 26 is cylindrical, a positioning groove 27 is opened at one end of the clamping member 26, and a test plate is jointly clamped by the upper ends of the four clamping members 26.

Specifically, when installing the test plate, by rotating the clamping screw 25, the distance between the two clamping members 26 is made close to the width of the test plate. When the four corners of the test plate are placed inside the positioning grooves 27 at the corresponding positions, and then the clamping screw is rotated to clamp the side wall of the test plate, so as to achieve the purpose of fixing the test plate.

[0044] In a further preferred embodiment of the present utility model, as Figures 1 - 5As shown, the detection module 33 includes a sliding table 37 which is slidably arranged inside the sliding groove 36, and a detector 38 is inserted at the bottom end of the sliding table 37.

[0045] In this embodiment, the sliding table 37 is provided for installing the detector 38, and Figure 3 it can be seen that a driving screw is arranged in the middle of the sliding table 37, and a motor is arranged at the end of the driving screw to push the sliding table 37 to move, so that the detector 38 slides over the surface of the coating layer to achieve the purpose of detecting various data of the coating layer;

[0046] Specifically, the detector 38 includes a friction detector, a pressure detector, a high-definition camera and a temperature detector, corresponding to friction test, pressure test, visual observation test and touch temperature test respectively.

[0047] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, the bottom end of the first threaded rod 43 is rotatably connected to the bottom plate 1, a rotating disc 45 is fixedly arranged at the upper end of the first threaded rod 43, and the second threaded rod 44 is rotatably connected to the rotating disc 45.
