Description

A kind of table tennis serve training device

technical field

The utility model relates to the field of sports auxiliary equipment, in particular to a table tennis serving training device.

Background technique

In table tennis competitions, the level of serving is the key for players to seize the opportunity in the game. However, most of the players' serving training is done by sparring partners, which is often inefficient and is not conducive to the players' correction of their own mistakes. And in training, the time to pick up the ball is even longer than the time to serve, which is also a waste of time. Therefore, the equipment that integrates picking up and delivering the ball is a good helper to help players train their serving level. Most of the ball-serving devices with a stirring structure are complex in structure and heavy, have a high failure rate, and are unstable in hitting intervals.

Contents of the invention

The purpose of the utility model is to provide a compact and efficient table tennis serving training device to solve the above-mentioned problems caused by the prior art.

A table tennis serving training device, comprising a collection frame, a chute, a ball passing cylinder, a ball passing screw, a head swing mechanism and a ball hitting mechanism, the bottom of the collection frame is open, and the lower end of the collection frame is fixedly connected in the chute, The chute is L-shaped, and the outlet is connected to the ball passing cylinder. There is a ball passing screw in the ball passing cylinder. The other end of the ball passing cylinder is equipped with a ball hitting mechanism. The head mechanism articulates two ball-hitting mechanisms.

Preferably, there is a ball net inside the collection frame, and the lower end of the ball net is fixedly attached to the inner side of the chute.

Preferably, the chute is an inclined chute, the height of the goal end is greater than the height of the ball exit end, and the baffles on both sides of the chute are higher than the height of the table tennis ball.

Preferably, the distance between the ball passing screw and the inner wall of the ball passing cylinder is greater than the diameter of the table tennis ball.

Preferably, the ball passing screw is supported in the ball passing barrel by a bracket.

The utility model has the advantages that: this kind of table tennis serving training device intercepts the ball served by the player through the net and falls into the lower chute, the chute transports the table tennis ball into the ball passing cylinder, and the ball passing screw in the ball passing cylinder Pass the balls to the exit of the passing cylinder in sequence, and fly the balls to the players through the hitting mechanism. This kind of device does not need to pick up the ball, which greatly improves the training efficiency of the players. The ball passing screw can pass the balls to the hitting place in sequence, so that the training can be kept orderly in the tense. The chute is placed obliquely, which ensures that the table tennis balls can fall into the ball passing cylinder by itself, and the distance between the ball passing screw and the inner wall of the ball passing cylinder is greater than the diameter of the table tennis ball, which improves the stability of the system and reduces the occurrence of jamming in the ball passing cylinder. The possibility of the ball and the stable support of the ball screw ensure the stability of the entire system.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific embodiments.

As shown in Fig. 1 and Fig. 2, a kind of table tennis serving training device comprises a collection frame 1, a chute 3, a ball passing cylinder 5, a ball passing screw 4, a head swing mechanism 6 and a ball hitting mechanism 7, and the bottom of the collection frame 1 It is an open type, the lower end of the collection frame 1 is fixedly connected in the chute 3, the chute 3 is L-shaped, and the outlet is connected to the ball passing cylinder 5, and the ball passing cylinder 5 has a ball passing screw 4 inside. The other end of the ball barrel 5 is provided with a hitting mechanism 6, and the swinging head mechanism 6 is fixed on the bottom of the ball passing barrel 5, and the swinging head mechanism 6 is movably hinged to two hitting mechanisms 7.

It is worth noting that there is a ball net 2 inside the collection frame 1 , and the lower end of the ball net 2 is fixedly attached to the inner side of the chute 3 .

In this example, the chute 3 is an inclined chute, the height of the goal end is greater than the height of the ball exit end, and the baffles on both sides of the chute 3 are higher than the height of the table tennis ball 8 .

In this example, the distance between the ball passing screw 4 and the inner wall of the ball passing barrel 5 is greater than the diameter of the table tennis ball 8 .

In addition, the ball screw 4 is supported in the ball barrel 5 by a bracket 10 .

Based on the above, this kind of table tennis serving training device intercepts the table tennis ball 8 sent by the player through the net 2 and falls into the lower chute 3, and the chute 3 transports the table tennis ball 8 to the passing cylinder 5, and the passing cylinder The ball passing screw 4 in the 5 passes the table tennis balls to the outlet of the ball passing cylinder 5 sequentially in 8 points, and the ball is sent to the player by the ball hitting mechanism 6, and the head swing mechanism 6 controls the ball hitting mechanism 7 to expand outwards and approach inwards , there is induction device in the head swing mechanism 6, after sensing the table tennis ball 8 at the outlet of the ball tube 5, the motor drives the swing mechanism 6 to drive the batting mechanism 7 to complete the batting action. This kind of device does not need to pick up the ball, which greatly improves the training efficiency of the players. The ball passing screw can pass the balls to the hitting place in sequence, so that the training can be kept orderly in the tense. The chute is placed obliquely, which ensures that the table tennis balls can fall into the ball passing cylinder by itself, and the distance between the ball passing screw and the inner wall of the ball passing cylinder is greater than the diameter of the table tennis ball, which improves the stability of the system and reduces the occurrence of jamming in the ball passing cylinder. The possibility of the ball and the stable support of the ball screw ensure the stability of the entire system.

It can be known from technical knowledge that the utility model can be realized through other implementations without departing from its spirit or essential features. Accordingly, the above-disclosed embodiments are, in all respects, illustrative and not exclusive.
