Problems solved by technology

[0002] It is well known that bunkers are often used for long jump training. Since the bunkers are exposed to the outside, the sand in the bunkers will harden if they are not used for a long time. Especially in winter and rainy seasons, rain and snow water entering the bunkers will cause sand The pits are more rigid. Stiff bunkers will make it impossible to train, e

Embodiment 1

[0026] Embodiment 1, the described bunker with loosening function, the folding canopy 6 can cover the bunker 2 by pulling the connecting rod 5, and the connecting rod 5 can be completely covered by placing the connecting rod 5 in the storage groove 11, and repeated Pulling the connecting rod 5 can make the loose structure loosen the sand in the sand pit 2, and the fixing hook 17 is connected with the fixing hole 18 to prevent sand or other foreign matter from entering the first slide rail 3 while pulling the connecting rod 5 Inside, this can increase the service life of the first slide rail 3, and can make the support rod 4 smoother during the sliding process, and the support rod 4 can be laid down in the process of using the sand pit so that the rake teeth 13 enter the slot 14 inside.

Abstract

The invention discloses a sandpit with a loosening function, and relates to the technical field of sports grounds. The sandpit with a loosening function comprises a sandpit body and a sand containing pit. The sandpit body is provided with the sand containing pit extending downwards. First sliding rails are correspondingly arranged on the two sides of the sand containing pit, and a shielding structure is arranged on the first sliding rails. The shielding structure is composed of two supporting rods, a connecting rod, a folding tent and a storage rod, wherein the supporting rods are located and slide in the first sliding rails, the connecting rod is arranged at the top ends of the supporting rods and located between the two supporting rods, and the folding tent is arranged on the connecting rod. The sandpit is simple and reasonable in structure, sand in the sandpit can be effectively loosened, the sand in the sandpit can be loosened in the shielding process, and the problem that the service life of a whole structure is affected by sand is solved.

Description

technical field [0001] The invention relates to the technical field of sports grounds, in particular to a bunker with a loosening function. Background technique [0002] It is well known that bunkers are often used for long jump training. Since the bunkers are exposed to the outside, the sand in the bunkers will harden if they are not used for a long time. Especially in winter and rainy seasons, rain and snow water entering the bunkers will cause sand The pits are more rigid. Stiff bunkers will make it impossible to train, especially the bunkers in the school. The sand in the bunkers after each holiday and school is very hard. Before training, the sand must be rearranged and loosened. In use, if some structures are set on the bunker to protect the bunker, some protective structures will be damaged and the service life will be affected because the sand will fly up during the training process. Contents of the invention [0003] In order to solve the problems in the prior ar...
