Description

Outdoor basketball net rainproof device

Technical Field

The invention relates to the technical field of basketball equipment, in particular to an outdoor basketball net rainproof device.

Background

At present, basketball sports are divided into indoor fields and outdoor fields according to fields, except high-grade stadiums such as basketball game stadiums and the like are the indoor fields, most basketball fields adopted by schools, parks and communities are outdoor equipment, basketball fields and basketball stands are outdoor, people know that most of nets hung on basketball rings are woven by ropes or are made of iron chains, the basketball nets on outdoor basketball stands are inevitably exposed, the basketball nets are easy to damage due to aging under the action of weather such as sunshine and rain, the basketball nets of the iron chains can rust quickly, particularly the aging degree of the basketball nets can be aggravated by hot sunshine in summer, expenses can be increased due to frequent replacement of the basketball nets, and the replacement of the basketball nets needs to be suspended by means of tables, chairs or ladders, so that a great number of adverse factors are increased.

CN 104056435A discloses an outdoor basketball net protection system, the concrete scheme includes that a fixing sleeve (4) is arranged on a basketball stand (2), an outlet (7) is arranged on a backboard (6), the outlet (7) is arranged above a basket ring (8), a baffle (1) is arranged in the outlet (7), one end of the baffle (1) is connected with one end of a connecting rod (3), the connecting rod (3) penetrates through the fixing sleeve (4), and a card (5) is arranged at the other end of the connecting rod (3); CN 105709385A discloses outdoor basketball net protection system and application method thereof, relates to basketball equipment field, is equipped with fixed cover (4) on basketball stands (2), is equipped with export (7) on backboard (6), and export (7) set up in the top of ring (8), is equipped with baffle (1) in export (7), and baffle (1) one end is connected with the one end of connecting rod (3), and fixed cover (4) are passed in connecting rod (3), is equipped with card (5) at the other end of connecting rod (3).

Compared with the traditional open-air basketball net, the two patents improve the protection of the basketball net to a certain extent, and the mode that the baffle is arranged above the basket ring is adopted, so that the problem that the basketball net is directly exposed to sunlight is effectively avoided, the structure is simple, the operation is convenient, and the simple baffle cannot really protect the basketball net well against bad weather such as wind, rain and the like.

The invention discloses an automatic-shrinkage outdoor basketball net protection system which comprises a support column and a shielding plate, wherein the shielding plate is arranged on the upper left side of the support column, the top of the shielding plate is an arc surface, a backboard is arranged at the left end of the shielding plate and is perpendicular to the shielding plate, a telescopic sleeve is arranged at the lower end of the backboard in a sliding mode, the left end of the telescopic sleeve is connected with a basket through a fixed rod, a sliding cavity is arranged at the right end of the telescopic sleeve, a sliding rod is matched at the right end of the sliding cavity in a sliding mode, the right end of the sliding rod is fixedly connected with the support column, a first reset spring is arranged in the sliding cavity and fixedly connects the sliding rod with the telescopic sleeve.

Above-mentioned patent has realized the perfect protection to ring and net at rainwater weather, but a problem is, the condition that this patent technique relied on is that the shrink to ring and net is realized utilizing the gravity of rainwater, so when the rainfall reaches not triggering this mechanical structure condition, also when the rainfall is little, the device can not withdraw the backplate with the net under, also can not avoid the net to drench by the rainwater, that is to say, this patent can not adapt to all rainwater weather, still can not realize the protection to the net, the practicality is not strong, and the structure is more complicated, and the cost is higher, also can not solve to the problem of high temperature solarization.

To sum up, present basket net protection technique to outdoor basketball stands is not perfect, though directly exposes in the outdoor basket net in the past and has improved the protection to the basket net to a certain extent, still can not realize the thorough protection to the basket net, consequently, how to realize the thorough protection to outdoor basketball stands basket net under any weather, the environment, prolongs the life of basket net to the at utmost, is the problem that present basketball equipment research personnel need to solve urgently.
