Problems solved by technology

[0002] The long jump is a track and field jumping event, and it is also one of the most common sports. The athletes in the long jump training competition are all completed in the sand pit on the ground. Fine sand is placed in the sand pit. The setting of the sand pit is convenient for the competition on the one hand. The measurement of the results, on the other hand, can effectively protect the athletes. Jumping in the bunker will not cause any harm to the athletes; It will be greatly reduced and affect the use of athletes, so it is very necessary to design a kind of cover sand platform device that can cover the sand pit when the bunker is not in use to prevent rain

Abstract

The invention belongs to the technical field of covering sand platforms, and particularly relates to a covering sand table device for long jump. The covering sand table device comprises a covering drive device and a fixed device. After a sandpit is used, the covering sand table device is transferred to the edge of the sandpit; then the fixed device is fixed; one end of a thin film is fixed on thefixed device; the covering drive device is placed on the upper side of the sandpit; and then the covering drive device is manually pulled to extend the thin film in the covering drive device outwardsto cover the sandpit, so that the influence on the use by athletes due to the fact that rainwater falls into the sandpit to cause caking and hardening of sand in the rainy weather during the non-usingprocess is prevented. During use, the covering drive device is pulled manually to retract the thin film in the covering drive device inwards to expose the sandpit.

Description

technical field [0001] The invention belongs to the technical field of sand platform covering, in particular to a sand platform covering device for long jump. Background technique [0002] The long jump is a track and field jumping event, and it is also one of the most common sports. The athletes in the long jump training competition are all completed in the sand pit on the ground. Fine sand is placed in the sand pit.
