The table tennis auxiliary training equipment in daily life is expensive and difficult to popularize civilian, and the table tennis table is relied on to embody basic conditions, and the civilian-grade product has poor specialty and can only be used for public entertainment. If a practice specific to the table tennis technique is to be performed, for example: the user needs to ask for coaches and find companions specially when the user pulls the ball with the front hand, pushes the gear with the reverse hand, and directly beats and violently, so that the user is limited in time and space. There are also many products on the market to improve the efficiency of table tennis practice, such as ball serving machines, ball picking machines, etc., which all depend on the necessary material condition, i.e., table tennis table. Many amateurs like to carry out simple exercise with the desk at home as the ping-pong table, but because the size of desk and standard table are great different, do not do benefit to the formation of technical action and muscle design, professional practicality is poor. Therefore, the technical method for reforming the household table into the standard or close to the table through lower cost has higher application value and practical significance.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a table tennis trainer which has the characteristics of simple structure, low production cost and high popularization.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a table tennis training device comprises a rebound board and a connecting piece; the connecting piece comprises a supporting plate, a rotary sliding assembly and an adjusting plate; one side of the supporting plate is horizontally connected with the desktop; the bottom edge of the adjusting plate is arranged on the rotary sliding assembly, the rotary sliding assembly is arranged on the supporting plate, so that the adjusting plate horizontally slides along the supporting plate and rotates by taking the rotary sliding assembly as a center, and the adjusting plate is arranged opposite to the table top, so that an included angle between the adjusting plate and the free side edge of the supporting plate is an acute angle;
the bottom end of the rebound plate is hinged to the upper end of the adjusting plate through an adjusting screw, so that the rebound plate and the adjusting plate are integrally in an L-like shape;
rotating the angle between the adjusting plate and the supporting plate to enable the height of the upper end of the adjusting plate relative to the table top to be the height of a standard ball net; the position of the adjusting plate on the supporting plate is moved, so that the distance between the falling point of the bottom end of the rebound plate vertically downwards on the horizontal plane of the table top and the free side edge of the table top is the length of the standard single-side table.
Furthermore, an L-shaped opening fixing piece is fixed below the end part of the supporting plate, a locking screw is arranged below the fixing piece, the fixing piece is clamped on the side edge of the desktop, and the locking screw is screwed down, so that the supporting plate is horizontally connected with the desktop, and the upper surface of the supporting plate and the desktop fall on the same horizontal plane.
Furthermore, the rotary sliding assembly adopts a slidable screw, and the slidable screw is elliptical.
Furthermore, the included angle between the adjusting plate and the free side edge of the supporting plate is smaller than 30 degrees.
Has the advantages that: the table tennis trainer provided by the invention enables the length and the net height of a household table to meet the size of a table tennis table, and can facilitate the practice of table tennis. The rebound board can control the rebound falling point to be kept on the table according to the hitting power and the rotation adjusting angle, thereby constructing a real hitting environment. If the hitting ball is too high, the rebound is easy to go out of the table, if the hitting ball is too low, the hitting connecting part shows that the net is off, and the hitting accuracy can be improved through repeated practice.

Detailed Description
The invention is illustrated below with reference to specific examples. It will be understood by those skilled in the art that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention in any way.
FIG. 1 is a current standard table in common use, which comprises a horizontal table 1 and a vertical net 2 arranged between the horizontal table 1; the horizontal table 1 is divided into two symmetrical table parts by the net 2, the length of the table parts on both sides is 137 cm, the height of the standard net is 15.2 cm, and the width of the standard net is the same as that of the horizontal table.
A table tennis training device, as shown in fig. 2 to 3, comprising a rebound board 8 and a connecting piece; the connecting piece comprises a supporting plate 4, a rotary sliding assembly 5 and an adjusting plate 6; one side of the supporting plate 4 is horizontally connected with the desktop 9; l-shaped opening-shaped fixing pieces 10 are fixed below the end portions of the supporting plate 4, locking screws 3 are arranged below the fixing pieces 10, the fixing pieces 10 are clamped on the side edges of the table tops 9, the locking screws 3 are screwed, the supporting plate 4 is horizontally connected with the table tops 9, and the upper surface of the supporting plate 4 and the table tops 9 fall on the same horizontal plane. The bottom edge of the adjusting plate 6 is arranged on the rotary sliding component 5, the rotary sliding component 5 is arranged on the supporting plate 4, so that the adjusting plate 6 horizontally slides along the supporting plate 4 and rotates by taking the rotary sliding component 5 as a center, and the adjusting plate 6 is arranged opposite to the table top 9, so that an included angle between the adjusting plate 6 and the free side edge of the supporting plate 4 is an acute angle;
the bottom end of the rebound plate 8 is hinged to the upper end of the adjusting plate 6 through an adjusting screw 7, so that the rebound plate 8 and the adjusting plate 6 are in an L-like shape integrally;
rotating the angle between the adjusting plate 6 and the supporting plate 4 to make the height of the upper end of the adjusting plate 6 relative to the table top 9 be the height of the standard net 2, namely 15.2 cm; the position of the adjusting plate 6 on the supporting plate 4 is moved so that the distance between the falling point of the bottom end of the rebound plate 8 vertically downwards on the horizontal plane of the table top 9 and the free side edge of the table top 9 is the length of the standard single-side table 1, namely 137 cm.
