Working principle:

[0033] In use, the base 1 provides a basic load bearing for the device, the top fixing frame 2 is used to install the electric telescopic rod 3, forming a vertical lifting structure of the fixing frame 2, the electric telescopic rod 3, and the support plate 4, the output end of the electric telescopic rod 3 drives the support plate 4 to move up and down, thereby adjusting the height of the bottom moving part 5 and the hardness detector 6, realizing the accurate alignment of the detection head and the sample, the support plate 4 is movably connected with the moving part 5, drives the second motor 832 inside the second L-shaped plate 831, drives the second screw 833 to rotate, converts the rotary motion into the linear motion of the second sliding block 81 through threaded transmission, drives the moving part 5 and the hardness detector 6 to move accurately along the second sliding groove 82, and the second motor 832 can realize the left and right movement of the detector respectively, the moving distance can be set through the controller of the second motor 832, the accurate positioning of the detection point is realized, and the detection range is expanded. During detection, the sample is placed on the top of the base 1, the first motor 742 is started, the screw is driven to rotate, and the two first sliding blocks 71 are driven to move synchronously and oppositely along the first sliding groove 72 through threaded transmission to clamp the sample. When holding the sample, the protective pad 10 directly contacts the surface of the sample, the sample extrudes the protective pad 10 to compress the spring 11, the elastic restoring force generated by the spring 11 pushes the protective pad 10 to tightly adhere to the surface of the product, realizing self-adaptive clamping. The telescopic characteristic of the spring 11 enables the protective pad 10 to slightly deform along the shape of the sample surface, improving the adhesion. Then, when the hardness detector 6 moves, the internal detection head contacts the surface of the sample, applies pressure and feeds back hardness data. The power source of the device is an integrated lithium battery pack inside the base 1, which is connected with the detector through wires, suitable for mobile detection scenes. Thus, the effect of fixed detection adjustment of plastic products is achieved. The damper 12 inside the groove 9 is arranged in parallel with the spring 11, one end is fixed to the bottom of the groove 9, and the other end is connected to the outside of the protective pad 10. The spring 11 is sleeved on the surface of the damper 12. When the protective pad 10 is extruded by the sample or affected by external vibration, the damper 12 expands and contracts synchronously. The internal damping structure of the damper 12 inhibits the high-frequency vibration of the spring 11 through friction energy dissipation, so that the clamping action of the protective pad 10 is more stable. The spring 11 provides continuous clamping force, and the damper 12 absorbs vibration energy. The two work together to stably fix the sample. The limiting rods 13 are symmetrically fixed to the top of the support plate 4 on both sides, the top ends vertically penetrate to the top of the fixing frame 2, and form a sliding fit with the penetrating hole of the fixing frame 2. When the electric telescopic rod 3 drives the support plate 4 to drive the hardness detector 6 to lift, the limiting rods 13 slide along the penetrating hole of the fixing frame 3 synchronously with the support plate 4. Through the fit constraint of the rod body and the hole wall, the horizontal deviation of the support plate 4 in the lifting process is limited, ensuring that the support plate 4 always moves smoothly along the vertical direction, thereby ensuring that the detection head of the bottom hardness detector 6 is accurately aligned with the sample.

[0034] In summary, this invention, by setting up a fixed frame 2, an electric telescopic rod 3, a support plate 4, a movable part 5, and a hardness detector 6, enables the hardness detector 6 to be vertically raised and lowered by the electric telescopic rod 3. Together with the movable part 5, it can adapt to the needs of samples with different thicknesses and different testing points. This solves the problems of poor versatility of existing plastic hardness testing equipment, the difficulty of its clamps in firmly fixing products of different specifications, and the inability of the testing device itself to be adjusted, which makes it difficult to guarantee the testing accuracy.
