Quick table tennis collecting device used for sports teaching

Abstract

The invention aims to solve the problems that an existing ball collecting device is likely to become loose, and manual picking takes much effort, and discloses a quick table tennis collecting device used for sports teaching. The quick table tennis collecting device comprises a containing pipe, a pull rod, a cavity, a collection plate, air guide plates, guide pipes and rotating rods. Through grooves are formed in the inner sides of the air guide plates, and air bags corresponding to the through grooves are uniformly installed on the inner side of the containing pipe. Extension type air bags are fixedly installed on the outer sides of the guide pipes respectively, magnetic blocks are fixedly installed on the upper sides of the rotating rods respectively, a sleeve is fixedly installed in the middle of the surface of the containing pipe, rotating blocks are installed between the sleeve and the rotating rods, and rotary shafts are installed between the rotating blocks and the sleeve. Through the attraction of the magnetic blocks, and the extension type air bags are extruded by the rotating rods, so that the air bags are inflated; the distance between the air bags becomes small, so that the resistance to table tennis is increased, and the table tennis is easily and quickly collected; the structure is simple, the design is reasonable, the operation is convenient, and the quick table tennis collecting device is worthy of popularization.

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
