Portable broad-jump measuring equipment

Abstract

Provided is portable broad-jump measuring equipment. The upper surface of a base is provided with a buffering cushion the upper surface of which is bonded with an elastic rubber pad, one end of the base is provided with a fixed standing platform, and the upper surface of the fixed standing platform is provided with a wear-proof cushion, wherein the other end of the base and the end portion of the fixed standing platform are both provided with pulley assemblies, each pulley assembly consists of a horizontal supporting plate which is fixedly connected to the base and the end portion of the fixed standing platform, and sliding columns vertically penetrating through the horizontal supporting plate; a pulley is arranged on the bottom of each sliding column; fixing bolts used for abutting against and fixing the sliding columns are arranged on the top wall of the free end of the horizontal supporting plate; the bottoms of the fixed standing platform and the base are both bonded with skid-proof cushions. The portable broad-jump measuring equipment, by utilizing the pulley assemblies, can move conveniently and has the advantages of being simple in structure and convenient to use; during use, the pulley assemblies can be stored; by placing the skid-proof cushions on the ground for use, since the elastic rubber pad is made of composite materials and high in elasticity and suppleness, the safety of personnel during landing is ensured.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to a portable long jump measuring device. Background technique [0002] In ordinary long jump training or competition, the traditional method is to use sand pits to measure athletes. This measurement method not only has high error and high labor costs, but also requires special personnel to measure. Changes are likely to bring errors to subsequent athletes. After the athletes walk out of the bunker, they will take the sand out of the bunker, and a small amount of sand will enter the athlete's shoes, which will increase the risk and bring great work to the sports staff. difficulty. In addition to bunker long jump, when jumping on the ground, playground runway and other roads, the athlete has no cushion when landing on the ground, and the athlete is prone to injury if he is not careful, and even if it is performed on the existing plastic track, the elastic cushion of the run...

Problems solved by technology

[0002] In ordinary long jump training or competition, the traditional method is to use sand pits to measure athletes. This measurement method not only has high error and high labor costs, but also requires special personnel to measure. Changes are likely to bring errors to subsequent athletes. After the athletes walk out of the bunker, they will take the sand out of the bunker, and a small amount of sand will enter the athlete's shoes, which will increase the risk and bring great work to the sports staff. difficulty

In addition to bunker long jump, when jumping on the ground, playground runway and other roads, the athlete has no cushion when landing on the ground, and the athlete is prone to injury if he is not careful, and even if it is performed on the existing plastic track, the elastic cushion of the runway surface is not enough. , there are still security risks

In addition, in general, there is no special long jump venue for outdoor long jump entertainment activities. The athletes either go to the playground together, or draw lines on the spot to measure, which is extremely inconvenient
