High-efficiency inflation device for volleyball used in sports training

Abstract

The invention discloses an efficient volleyball inflating device for physical training. The device includes a base; a vertical box body is fixedly mounted on the top surface of the base; a first through hole is formed in the top center of the box body; a second through hole is formed in the bottom center of the box body; a third through hole is formed in the top surface of the base corresponding to the second through hole; a vertical inflation needle is arranged in the box body and sequentially penetrates through the first through hole, the second through hole and the third through hole; a horizontal piston plate is arranged in the box body; the bottom face of the piston plate and the inner wall of the box body form a first cavity; a fourth through hole is formed in the center of the piston plate; fifth through holes are formed in the top face of the piston plate and located on the left and right sides of the inflation needle; and vertical bars are arranged at left and right sides of the inflation needle. The volleyball inflating device is ingenious in structure, capable of effectively changing the air pressure in volleyballs by rotating the circular plate, capable of adapting to training of different degrees, capable of automatically popping up inflated volleyballs, high in automation degree and reliable to use and capable of automatically collecting the inflated volleyballs,is used without worrying about insufficient or excessive inflation, and has high efficiency.

Description

technical field [0001] The invention belongs to the field of inflation devices, in particular to a high-efficiency inflation device for volleyball used in sports training. Background technique [0002] In some sports training, when the volleyball is inflated, the volleyball is generally inflated by manually opening the inflation device. In this way, in the process of inflation, the amount of inflation is based on experience, and the air pressure in each volleyball cannot be guaranteed. , this is easy to affect the feel of the training athletes and affect the training efficiency, and the air pressure in the volleyball cannot be quickly and efficiently rushed to the optimal air pressure during the inflation process, which is not very convenient to use, especially some volleyballs that use the number of Many training venues do not have stable, efficient and reliable automatic inflation equipment. Contents of the invention [0003] The invention provides a high-efficiency vol...
