[0002] Obstacle running is a kind of sports, including 400M and 800M and other obstacle running sports. The obstacles mentioned in it are obstacle hurdles. The hurdle structure in traditional competitions is single, which is not suitable for teaching. Not only can it not adjust the teaching hurdles The height of the body cannot buffer the impact when the student fails to cross the teaching hurdle body and falls to the ground. It is difficult to automatically straighten the teaching hurdle body after falling to the ground. It is conducive to the teaching and training of hurdles in obstacle running. The exposed hard metal is easy to cause injury to students, and the safety performance is low.

The invention discloses a gravity balance device for a robot arm, which comprises a hurdle body for teaching, a lift rod limiting groove inside the hurdle trunk, a lift adjustment rod inside the lift rod limit groove of the hurdle trunk, and a lift adjustment rod on the top of the hurdle. The elevating rod is used to fix the rod, and the beneficial effects of the present invention are as follows: on the premise of accurately adjusting the height of the teaching hurdle body, the present invention can buffer the impact when the student fails to cross the teaching hurdle body and falls to the ground. Afterwards, the hurdle body for teaching can be automatically righted, which is convenient for the coach to recover; it is convenient to adjust the indication angle of the teaching indicator light mechanism during use, and prompt the students for the best take-off position after the indicator light shines on the ground, which is convenient for the teaching and training of hurdles in obstacle running. Simultaneously, the plumb adjustment mechanism can provide counterweight effect for the present invention, keep the obstacle horizontal bar to keep level, make it more standard and professional; Prevent hard metal from causing injury to the students, make the present invention have higher safety performance.
