Sports hurdle frame

Abstract

The invention provides a sports hurdle frame. The sports hurdle frame comprises a cross rod, connecting pieces, supporting pieces, stabilizing pieces and bearings. All the rods can be folded; the connecting pieces enable sleeve rods and fixing rods to be connected in a rotating mode. When a student hurdles a hurdle, the cross rod is touched; the cross rod can rotate along the force direction, so that the student is prevented from being stumbled; the problem that the joint is easy to break in the prior art is solved; the spring specially designed in the connecting piece can be used for limitingthe rotating angle, so the corner of the cross rod is prevented from being overlarge; the height of the hurdle is adjustable through cooperation of a gear and a rack, a matched ruler can be adjustedaccording to students of different ages or heights, the length is adjustable through cooperation of the sleeve rod and the sliding rod, the requirements of students of different ages are also met, andthe folding size can be smaller.

Description

technical field [0001] The invention relates to the technical field of sporting goods, in particular to the technical field of a sports hurdle frame. Background technique [0002] 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. The inverted crossbar is even more frightening for beginners. [0003] There are many designs for the hurdle frame in the prior art, but all of them have different defects. For example, the patent application number 201610978842.3 designs a sports hurdle frame, but this design cannot completely fold the hurdle frame. It is cumbersome to disassemble the body and install it when using it. The support itself is cumbersome and easy to trip students. The two designed belts are connected by magnets.

[0003] There are many designs for the hurdle frame in the prior art, but all of them have different defects. For example, the patent application number 201610978842.3 designs a sports hurdle frame, but this design cannot completely fold the hurdle frame. It is cumbersome to dismantle the body and install it when using it. The support body itself is cumbersome and easy to trip students. The two designed belts are connected by magnets. In the daily training of students, it is inevitable that there will be metal objects on their bodies. During training, the magnet attracts metal objects, which easily affects the training of students and causes unnecessary troubles. At the same time, during the training process, if the student's body touches the belt body, the belt body will drive the upper pole to rotate, but the connection between the two will be twisted Force, easy to break after reciprocating many times
