Description

A kind of table tennis flight landing point control device

technical field

The utility model belongs to the field of sports training devices, and in particular relates to a table tennis flight drop point control device.

Background technique

For table tennis beginners, when learning the basic technique of table tennis, the flight trajectory of the table tennis ball is too high and the landing points are scattered. By requiring the table tennis beginners to push and block the table tennis ball to pass through the restricted space area, only when the table tennis beginners actively extend their arms forward and the table tennis racket leans forward can they meet the requirements for mastering the technical movements, and then correct the table tennis pushing and blocking technical movements the goal of. The purpose of table tennis is to mobilize the opponent and cause mistakes through the change of the landing point, so that one's own side can score and win. By setting different sizes of landing areas, cultivate the awareness of table tennis fans to control the landing, and improve the muscle control ability and technical and tactical level of table tennis fans. By effectively changing the drop point of the table tennis ball, the scoring rate of the table tennis game is further improved.

Existing table tennis technique teaching is a teaching process in which teachers demonstrate and students imitate exercises without any special equipment assistance. Only under the specific guidance of the professor, the learners can further improve the technical movements. Due to the influence of the learners' physical coordination, psychological quality and comprehension ability, the efficiency of improving technical movements is often low and the effect is poor, which affects autonomy. Learning progress, feel that the practice process is boring, and the concentration and interest in learning are reduced.

Utility model content

The technical problem to be solved by the utility model is to provide a table tennis flight drop point control device that can effectively assist teaching and control the drop point.

The utility model is achieved in this way, the device includes a lifting rod, a fixing clip, a frame and a plurality of sliders, wherein the size of the frame matches the size of one side of the table tennis table, the frame is composed of frame rods, two parallel frame rods and a The frame rod on one side is connected through a right-angled connecting pipe, and connected to the frame rod on the other side through two cross-shaped fixing clips. The two lifting rods are respectively installed on the fixing clips on both sides. Insert it into the vertical tube of the cross-shaped fixing clip, set the screw fastening handle on the fixing clip, loosen and fix it through the screw fastening handle to form a vertical space with different heights, set the slider on the frame rod, corresponding to the two sliders A horizontal dividing line and a vertical dividing line are arranged between them, and through the movement of the slider on the frame bar, the horizontal dividing line and the longitudinal dividing line intersect to form regions of different sizes. The slider is T-shaped;

Further, frames and right-angle connecting pipes are arranged symmetrically on both sides of the lifting rod.

Compared with the prior art, the utility model has the beneficial effects that:

Utilizing the height difference of the existing table tennis net and the height difference of the lifting rod line, the flight track of the table tennis ball is controlled within the space of the height difference. In order to ensure that the table tennis ball flies in a specific space, table tennis practitioners can only complete the technical action requirements with the technical action of extending the forearm forward and tilting the table tennis racket forward. With the reduction of the height difference space, the hitting speed of the table tennis ball can be improved, and the table tennis ball can be guaranteed to fall in the table tennis table.

Use the moving slider to move the rubber bands to intersect to form plane areas of different sizes. Table tennis practitioners are required to drop the table tennis balls in the designated area to achieve "where to point and where to hit". By adjusting the size of the area and the distance of the area, the difficulty of the exercise can be adjusted to achieve multi-function.

The utility model is easy to install and use (it can be realized by plugging, pulling, and clamping); strong practicability and multiple functions (correction of technical actions, control of landing points, and adjustable exercise difficulty); strong interest (traveling, joyful experience of success); safety High reliability and low cost (it can be realized by using plastic, rubber band or string)

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figure 1, the device includes a lifting rod 2, a fixing clip 6, a frame 3 and a plurality of sliders 4, wherein the size of the frame 3 matches the size of one side of the dividing line of the table tennis table, and the frame 3 is composed of frame rods, which are parallel to each other. The two frame rods on one side are connected with the frame rod on one side through the right-angle connecting pipe 5, and the frame rod on the other side is connected through two cross-shaped fixing clips 6, and the two lifting rods 2 are respectively installed on the fixing clips 6 on both sides, and the lifting rod 2 The upper end is connected to the height line 1, and the lifting rod 2 penetrates into the vertical tube of the cross-shaped fixing clip 6. The fixing clip 6 is provided with a screw fastening handle, which is loosened and fixed by the screw fastening handle to form a vertical space with different heights , a slider 4 is set on the frame rod, the slider 4 is T-shaped, and a horizontal dividing line and a vertical dividing line are arranged between the corresponding two sliders. By moving the slider on the frame rod, the horizontal dividing line and the longitudinal dividing line Intersections form areas of varying sizes.

How to install this device:

First, the slider 4 is inserted into the frame rod, and the frame rod is inserted into the right-angle connecting pipe 5 to form a frame. Then insert the lift rod into the lift rod retaining clip. The top of the lifting rod is connected with a rubber band and tightened by the tension of the rubber band; the rubber band is connected with the slide block 4 and is tightened by the tension of the rubber band. Spaces of different heights and areas of different sizes are formed through the up-and-down lifting of the lifting rod and the movement of the slide block 4 .

As shown in FIG. 2 , the assembled device can be directly placed on the table 7 .

Example 2

The difference from Embodiment 1 is that frames and right-angle connecting pipes are arranged symmetrically on both sides of the lifting rod.
