Abstract

A noctilucent standing long jump testing device comprises a testing plate and a display, wherein an ultrasonic wave distance sensor electrically connected to the display is installed on one side of the testing plate; the testing plate comprises a steel plate and a composite layer; the composite layer is composed of an elastic layer and a noctilucent paint layer; ruler lines are disposed on the upper surface of the noctilucent paint layer; and the elastic layer is made of 30-35 parts of a phenolic resin matrix, 16-20 parts of rosin, 9-15 parts of polystyrene, 4-8 parts of polytetrafluoroethylene, 13-20 parts of nano glass fibers, 12-18 parts of carbon fibers, 20-25 parts of boron nitride, 5-10 parts of bismuth oxide, 12-18 parts of calcium hydroxide microcapsule powder and 10-15 parts of a waterproof agent. The device provided by the invention has the advantages that the elastic layer has enough elasticity, so that knee joints can be effectively protected, and body injuries are avoided; a grade can be observed preliminarily by the ruler lines; and the display screen can display an accurate grade detected by the ultrasonic wave distance sensor.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to a luminous standing long jump testing device. Background technique [0002] Standing long jump is a sport that develops the explosive power and jumping ability of the lower limbs. It requires the coordination and rapid force of the lower limbs and hip muscles, and cooperates with the swing of the upper limbs, so it also requires a certain degree of dexterity; the standing long jump is simple and easy to perform. You can practice on flat ground. When jumping, the legs are slightly separated, the knees are slightly bent, the body is leaning forward, and then the arms are naturally pre-swing twice forward and backward, and the legs are flexed and extended accordingly. Kick off the ground, fully straighten the knee joints and at the same time stretch the hips and jump forward, push the body forward as far as possible, the body forms a diagonal line in the space, after passi...
