Quick table tennis collecting device used for sports teaching

Abstract

The purpose of the present invention is to solve the problem that the existing device for collecting balls is easy to loosen and manual picking is laborious. It discloses a fast table tennis ball collection device for physical education teaching, which includes a holding tube, a pull rod, a cavity, a collection tray, An air guide plate, a conduit and a rotating rod, the inner side of the air guide plate is evenly opened with a through groove, the inner wall of the containing tube is evenly equipped with an air bag corresponding to the through groove, and the outer side of the catheter is fixedly installed with a telescopic air bag, the A magnetic block is fixedly installed on the upper side of the rotating rod, a sleeve is fixedly installed in the middle of the surface of the containing tube, a rotating block is installed between the sleeve and the rotating rod, and a rotating shaft is installed between the rotating block and the sleeve. In the present invention, through the attraction of the magnetic block, the rotating rod squeezes the telescopic air bag to inflate the air bag. By reducing the distance between the air bags, the resistance to the table tennis balls is increased, and the table tennis balls can be quickly collected. And the structure is simple, the design is reasonable, the operation is convenient, and it is worth popularizing.

Description

technical field [0001] The invention relates to the field of sports, in particular to a device for quickly collecting table tennis balls for physical education teaching. Background technique [0002] When performing table tennis training, multi-ball training is required. Although there is a collection net, it is not possible to collect all the balls. The balls that fall on the ground need to be picked up manually, which is a waste of time and consumes Physical strength, when performing table tennis training, there will be a phenomenon of lack of physical strength. The existing device is to intertwine thin ropes at the bottom of the frame, and then collect the balls through the gaps between the thin ropes, but after a period of use like this It will make the string loose, so it is easy to drop the table tennis balls when picking up the table tennis balls, wasting the time of collecting table tennis balls, and some use large-scale ball collection devices, but it is inconvenien...

[0002] When performing table tennis training, multi-ball training is required. Although there is a collection net, it is not possible to collect all the balls. The balls that fall on the ground need to be picked up manually, which is a waste of time and consumes Physical strength, when performing table tennis training, there will be a phenomenon of lack of physical strength. The existing device is to intertwine thin ropes at the bottom of the frame, and then collect the balls through the gaps between the thin ropes, but after a period of use like this It will make the string loose, so it is easy to drop the table tennis balls when picking up the table tennis balls, wasting the time of collecting table tennis balls, and some use large-scale ball collection devices, but it is inconvenient to operate and store. It is inconvenient to collect and increases the manufacturing cost
