Description

Technical Field

[0001] The invention relates to the technical field of sports equipment detection, in particular to a sports equipment strength detection device. Background Art

[0002] Sports equipment is a general term for various apparatuses, equipment and supplies used in competitive sports and fitness exercises. Parallel bars are one type of sports equipment. After manufacturing or after long-term use, the compressive strength of the parallel bars generally needs to be tested. After searching, the Chinese invention patent with publication number CN118913932B discloses a parallel bar sports equipment strength detection device. Through the setting of the first hydraulic press and the first clamping mechanism, when the first hydraulic press is started, the first force rod can move downward, and the pressure plate simultaneously applies downward pressure to the connecting rod and the bar body, thereby simulating the action of an athlete getting on the bar from the end of the bar body, and then detecting the strength of the connecting rod and the bar body according to the shape changes of the connecting rod and the bar body.

[0003] The above-mentioned sports equipment testing equipment has certain defects when performing strength testing on parallel bars equipment. For example, when testing parallel bars equipment, although the testing end can be adjusted to meet the compression resistance testing work at different positions; however, the detection driving force angle of the strength testing equipment is not adjustable, and it only has the function of performing strength testing vertically downward. It should be noted that athletes need to swing, swing over, flex and extend, and other movements at these positions, and the parallel bars are subjected to multi-directional forces. For example, when athletes are using them, their body center of gravity is mostly in the middle of the parallel bars, resulting in the parallel bars being subjected to pressure that is not only in a vertical downward state, and it lacks the function of simulating the athletes' usage scenarios.
