Description

Portable Tennis Serve Training Device

technical field

The utility model relates to a sports training article, in particular to a portable tennis serving training device.

Background technique

Compared with the world, my country's tennis level is relatively backward. The main problem is the lack of professional tennis training venues. However, due to my country's national conditions, it is impossible to build a large number of professional tennis courts. At the same time, standard tennis courts cannot accommodate a large number of people to participate in training. This point is particularly obvious for primary and secondary schools in big cities. The existing simple tennis training device also has the problems of inconvenient use and difficult carrying. For the above problems, it is necessary to develop a tennis training device that is easy to carry and is not limited by the venue. .

Utility model content

In order to overcome the above-mentioned technical problems, the utility model provides a portable tennis serving training device that is easy to carry and is not limited by the venue. The technical scheme adopted is as follows:

The portable tennis serving training device includes a base on which an inflatable box with an inflation port is arranged. A main pole is hinged on both sides of the inflatable box. The main pole is a hollow structure with a An extension rod, the end of the main pole is provided with a tenon structure, and the tenon structure is also respectively hinged to a diagonal strut and a support bar. The training device also includes a collection net, and the periphery of the collection net has a reinforced edge. The periphery of the collection net is fixedly connected with the main pole, the inflatable box, the end of the diagonal strut and the end of the extension rod respectively, and a collection bag is arranged at the bottom of the collection net.

Further, the main pole and the extension pole are made of carbon fiber.

Further, the support rod is hinged with legs.

Further, the base is several parallel aluminum alloy profiles, and the length of the profiles is greater than the width of the inflatable box.

Using the above portable tennis serving training device, the device can be easily deployed for serving training, and it has a ball collection device, which does not need to waste time picking up the ball. At the same time, the device adopts a hinged structure. After the inflatable box is deflated, each component can be easily Fold and carry.
