Description

A height-adjustable hurdle frame

technical field

The utility model belongs to the technical field of sports equipment, in particular to a height-adjustable hurdle frame.

Background technique

Hurdles is a very skillful sport. In the early stage of hurdling, people are always afraid. They are afraid of hitting the railing, or even riding on the railing and falling into a big somersault. High-level athletes often stumble when watching hurdling competitions. Inverted crossbars are even more frightening for beginners. The hurdle frame is a bracket used to support the crossbar when hurdling. Most of the hurdle frame fixing crossbars in the existing design use screws. Once fixed, it is very troublesome to disassemble. It is firm, and once beginners hit the railing or ride on the railing, it will be very dangerous. The existing hurdles have great safety hazards. Now the hurdles used by major schools cannot adjust the height, and it is difficult for beginners and girls to step over the hurdles shelf.

Utility model content

The purpose of this utility model is to provide a height-adjustable hurdle frame to solve the problems raised in the above-mentioned background technology.

In order to achieve the above object, the utility model provides the following technical solution: a height-adjustable hurdle frame, including a sleeve, a vertical rod, a cross bar, a tripod, a base, a connecting rod, a gravity block and a magnetic positioning block, the sleeve The inside of the casing is provided with a chute, the outer side of the casing is equipped with a positioning pin, the vertical rod is installed inside the casing, the vertical rod is provided with a blind hole, and the vertical rod is provided with a protrusion. The cross bar is docked and fixed with the protrusion of the vertical bar through the groove at the bottom, the connecting rod is fixed on the vertical bar by bolts, the vertical bar is fixed on the tripod, and the tripod is fixed on the base by bolts, The gravity block is installed in the inside of the tripod.

Preferably, the sleeve is provided with a through hole, and the diameter of the through hole is the same as that of the blind hole.

Preferably, the magnetic positioning block is arranged on the pole.

The technical effects and advantages of the utility model: the new height-adjustable hurdle frame uses magnetic force to fix the hurdle bar. When a beginner rushes to the hurdle frame in front, the hurdle bar will only move forward and downward, thereby avoiding wrestling and A series of problems such as riding on the hurdle crossbar have greatly improved the safety of teaching. The pole and the bushing are connected by a fixed pin. After knocking down, there is no need to adjust the height of the hurdle, and the fixed pin can also be removed. Allow the pole to slide inside the sleeve to adjust the height of the hurdle.
