Abstract

The invention relates to a multiplayer fitness and entertainment machine that realizes fitness and entertainment by firing table tennis balls. It includes launching, up and down reciprocating, height adjustment, and rotating mechanisms. Hit the ball in four directions, the launch tube is equipped with a batting plate and a launching spring, the incomplete gear is driven by the batting motor, and the driven gear is coaxially installed with the upper wire wheel. The upper support is surrounded by 4 angle aluminum, on which the upper support beam is housed, and the batting motor is contained on the upper support beam. Serving process: The batting motor drives the incomplete gear to rotate. When the incomplete gear meshes with the driven gear, the driven gear rotates and the upper wire wheel on the same axis also rotates and winds the wire, which is pulled by the guide rope wheel and the batting pull rope. The batting plate compresses the launch spring so that the launch spring has elastic potential energy. When the incomplete gear and the driven gear are not meshed, the elastic force of the launching spring is recovered, and the upper wire wheel is pulled to reverse while the batting plate has kinetic energy to eject the table tennis ball.

Detailed ways

The invention can automatically serve the ball from four directions at the same time, the direction of the serve is adjustable, the landing point is random, the height of the whole machine can be adjusted, the whole machine can be rotated, and the movement is convenient.

The invention includes a launching mechanism, an up and down reciprocating mechanism, a height adjusting mechanism and a rotating mechanism.

As shown in the accompanying drawings, the launching mechanism is arranged on the upper floor, consisting of a ball collecting basket 1, a pipe 2, a launching tube 3, a table tennis ball 4, a batting plate 5, a launching spring 6, an incomplete gear 7, a driven gear 8, and a batting ball. Motor 24, guide rope wheel 9, batting stay cord 10, upper wire wheel 11, upper support 27, upper support crossbeam 28 form. The ball-collecting basket 1 is divided into four areas, and each area is connected with four launch tubes 3 by a pipe 2 to realize simultaneous hitting in four directions. Driven by the batting motor 24, the driven gear 8 is coaxially installed with the upper wire wheel 11. Upper support 27 is surrounded by 4 angle aluminums, and upper support beam 28 is installed on it, and batting motor 24 is contained on the upper support beam 28. Serving process: the batting motor 24 drives the incomplete gear 7 to rotate. When the incomplete gear 7 meshes with the driven gear 8, the driven gear 8 starts to rotate and the upper wire wheel 11 on the same axis also starts to rotate and wind the wire. The rope wheel 9 and the batting stay cord 10 drag the hitting plate 5 to compress the launching spring 6, so that the launching spring 6 has elastic potential energy. When the incomplete gear 7 and the driven gear 8 were not meshed, the elastic force of the launching spring 6 recovered, and the pulling upper wire wheel 11 reversed while the batting plate 5 had kinetic energy to eject the table tennis ball 4. Repeat this to achieve continuous serving. People only need to stand on the ground near the exit of the launch tube 3, and take the table tennis ball 4 sent out from the launch tube 3 with a racket to return to their own area in the ball basket 1, or they can use the ball basket to pick up and launch it. Table tennis, the player who catches more balls wins.

What is installed below the launch mechanism is the up and down reciprocating mechanism. The middle bracket 29 of the up and down reciprocating mechanism is surrounded by 4 angle aluminum, and the middle bracket beam 30 is installed on it, and the reciprocating motor 25 is contained on the middle bracket beam 30. On the 25 shafts of the reciprocating motor. Four upper support guide rods 12 lower ends are fixed on the middle support 29, and the upper ends pass the upper support 27. Upper support guide rod 12 is with guide rod spring 13, and guide rod spring 13 one ends are fixed with middle support 29, and the other end is fixed with upper support 27. When the reciprocating motor 25 rotates forward, it drives the lower wire wheel 16 to rotate. One end of the upper support stay cord 14 is connected with the lower wire wheel 16, and the other end is connected with the upper support crossbeam 28. The upper support stay crossbeam 28 is pulled by the upper support stay cord 14 to make the launching mechanism Move down along the upper bracket guide rod 12, and now the guide rod spring 13 on the upper bracket guide rod 12 is compressed; The elastic force of the guide spring 13 on the support guide rod 12 is released, so that the firing mechanism moves upward along the upper support guide rod 12 . Repeatedly, the launching mechanism reciprocates up and down, and the height of the serving point changes accordingly, so that the position of the falling point changes constantly, increasing the difficulty of catching the ball.

The height adjustment mechanism is arranged below the up and down reciprocating mechanism. The height adjustment mechanism is composed of four parallelogram-shaped connecting rods 17, screw rod 18, lower guide rod 15, connecting plate 31, and nut connecting plate 32. The two ends of the connecting rod 17 They are respectively hinged with the connecting plate 31 and the nut connecting plate 32. The nut connecting plate 32 is threaded, and screwed with the screw rod 18, the rotating screw rod 18 can change the state that the connecting rod 17 is surrounded by a parallelogram, so that the middle bracket 29 moves upward or downward to realize the height adjustable function of the whole machine. The height of the racket player is adjusted, and the height adjustment mechanism can directly adopt a commercially available jack.

Rotating mechanism is installed below the height adjusting mechanism, is positioned at the lowest floor, consists of universal wheel 19, base 33, base beam 34, base connecting plate 37, rotating motor 26, planetary gear 20, central gear 21, support seat 22, support shaft 23 , Locating pin 35, friction pad 36 form. Base 33 is surrounded by 4 angle aluminum, is installed with base beam 34 on it, and base connecting plate 37 is fixedly connected below base beam 34, and bearing is installed in the center, and support shaft 23 is fixed with bearing inner ring, makes base connecting plate 37 and support The shaft 23 is relatively rotatable, and the rotation motor 26 is also installed on the base connecting plate 37 . The support base 22 is set on the support shaft 23, and the bottom of the support base 22 is fixed with a friction pad 36. Both the support base 22 and the support shaft 23 are provided with two pin holes, and positioning pins 35 are installed in the pin holes for adjusting the support base. 22 in height. The central gear 21 is fixedly connected with the support shaft 23, and the planetary gear 20 is mounted on the shaft of the rotating motor 26 and meshes with the central gear 21. When the support seat 22 is placed at the lowest position, the friction pad 36 is pressed against the ground, so that the central gear 21 is fixed, and the rotation motor 26 is turned on to make the planetary gear 20 rotate around the central gear 21 and drive the whole machine to revolve around the central gear 21. rotate. At this time, the person who shoots the ball needs to run around to catch the ball with the rotation of the whole machine, and the difficulty of catching the ball is further improved.

When the complete machine needs to be moved, the support base 22 is promoted to leave the ground, and the positioning pin 35 is inserted into the upper pin hole on the support shaft 23 to get final product.

For first-time users, it is not necessary to start the reciprocating motor and the rotating motor, so that the whole machine does not move up and down and rotates, but only has the action of hitting the ball, which greatly reduces the difficulty of catching the ball.
