Problems solved by technology
[0004] Aiming at the deficiencies of the prior art, the present invention provides a test device for the surface material of the sports field, which solves the problem that the test device used in the production process of the current plastic runway is usually only a simple reciprocating extrusion test on the surface of the material. In actual use, the runway needs to be squeezed from multiple angles, which leads to the problem that the detection cannot fit the reality and the accuracy of the test results is poor.

The invention discloses a device for testing the surface material of a sports field, which specifically includes: a test bench, a fixing frame is fixedly connected to both ends of the top of the testing bench, and a lifting rod is fixedly connected to the inner wall of the fixing frame, and the lifting rod is far away from the fixed One end of the frame is fixedly connected with a fixed seat; the detection device is arranged at the center of the top of the test bench, and the bottom of the detection device is fixedly connected with the test bench; the detection device includes: a positioning plate, and an arc The arc-shaped slide hole is fixedly connected to the part of one side of the positioning plate above the arc-shaped slide hole. The invention relates to the technical field of sports field surface material testing. This test device for the surface material of sports grounds can squeeze the material to be tested at multiple angles, the test is more suitable for actual use, the test result is more accurate, and it is convenient to freely adjust the test conditions, and can test the test under different pressures Material resistance.
Description
A testing device for surface material of sports field technical field The present invention relates to the technical field of sports ground surface material testing, and is specifically a kind of sports ground surface material testing technology. test device. Background technique The sports field is the best place to exercise, and the surface of the sports field is generally paved with rubber runways. The friction between the surface and the athlete, the plastic track, also known as the all-weather track and field track, is made of polyurethane prepolymer, mixed polymer It is composed of ether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives and fillers. The plastic track has good flatness and compression resistance. The characteristics of high strength, appropriate hardness and elasticity, and stable physical properties are conducive to the performance of athletes' speed and skills, and effectively improve the performance of athletes. ...
