The application mode of the utility model is as follows: firstly, stretching the badminton net cloth 1 and arranging net cloth stretching and bearing devices 2 on two sides of the badminton net cloth 1 in place; the hand wheel 15 is manually rotated, so that the hand wheel 15 drives the rotating screw rod 14 to rotate, and the rotating screw rod 14 drives the guide seat 16 to move up and down along the sliding rail 12, so that the guide seat 16 and the mesh rope pulley 18 can be driven to move up and down; the badminton net cloth 1 can be driven to wholly ascend or descend; the high and low positions of the badminton net cloth 1 are adjusted to meet the requirements of people with different heights;
after the position of the badminton net cloth 1 is adjusted, a certain number of round balancing weights 8 are added on the balancing weight chassis 7, so that the badminton net cloth 1 is always in a tensioning state;
however, if during the outdoor badminton training process, because there is wind outdoors, the originally tensioned badminton net cloth 1 is inevitably slightly loosened, at this time, the hand rocking rod 11a can be lifted up, the hand rocking rod 11a drives the hand rocking shaft 11b to rotate, as shown in fig. 3 or fig. 4, the originally vertical oval weight chassis top block 11c is inverted into a horizontal shape, as shown in fig. 6-fig. 7, after the lifting handle rocking rod 11a is lifted, the weight chassis 7 lacks the support of the oval weight chassis top block 11c, and the weight chassis 7 drives the whole weight mechanism to move downwards, so that the slightly loosened badminton net cloth 1 can be tensioned again.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model. Thus, the present utility model is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
