DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-6 The utility model is described in further detail.

[0035] Example 1

[0036] like Figures 1-6 As shown, in order to solve the existing problems, the utility model discloses a ball throwing device in this embodiment, including a base 1 and a support column 2 connected to the top of the base 1, a support plate 3 connected to the top of the support column 2, a housing 4 connected to the top of the support plate 3 through a connecting column, the housing 4 is provided with a blanking component 5, and the support plate 3 is connected to a driving component 6;

[0037] The top of the support plate 3 is connected to a launch shell 8 , and a through hole is provided on the top of the launch shell 8 . The through hole is located directly below the shell 4 and passes through both ends of the launch shell 8 .

[0038] The driving component 6 includes a rotating motor 601 connected to the bottom of the support plate 3, the output end of the rotating motor 601 passes through the support plate 3 and is connected to a driving gear 602, the driving gear 602 is rotatably connected to the support plate 3, a plurality of circumferentially distributed limiting holes are provided on the top of the driving gear 602, the driving gear 602 is rotatably connected to a rotating connecting rod 603 through the limiting holes, the other end of the rotating connecting rod 603 is rotatably connected to a sliding rod 604, the bottom of the sliding rod 604 is slidably connected to the support plate 3, the top of the sliding rod 604 is connected to a push rod 605, the top of the support plate 3 is rotatably connected to a driven gear 606, the driven gear 606 is meshed with the driving gear 602, the driven gear 606 is provided with a connecting shaft, the connecting shaft passes through the support plate 3, and the end of the connecting shaft away from the driven gear 606 is connected to a torsion spring assembly 607;

[0039] Furthermore, the torsion spring assembly 607 includes a torsion spring housing connected to the bottom of the support plate 3, a torsion spring is connected to the inner wall of the torsion spring housing, and the other end of the torsion spring is connected to the side of the connecting shaft. The structure of the driven gear 606 is the same as that of the driving gear 602. Two sets of rotating connecting rods 603 are provided on the top of the support plate 3, and the two sets of rotating connecting rods 603 are respectively rotatably connected to the driving gear 602 and the driven gear 606.

[0040] The push rod 605 is rotatably connected to one end of the sliding rod 604 and is connected to an inclined push plate 7. The other end of the inclined push plate 7 is connected to a push member 9. The width of the inclined push plate 7 is smaller than the width of the launching shell 8. Several feet are provided at the bottom of the base 1, and anti-slip pads are provided at the bottom of the several feet. A sliding groove is provided at the top of the support plate 3, and the bottom of the sliding rod 604 is slidably connected to the inner wall of the sliding groove.

[0041] The specific working principle is: the driving gear 602 is driven to rotate by the rotating motor 601, thereby realizing the power transmission effect of launching tennis balls by the device. When the rotating motor 601 is working, the driving gear 602 drives the driven gear 606 to rotate. At this time, the rotation of the driven gear 606 causes the elastic rotational potential energy to be stored inside the torsion spring assembly 607, and as the driving gear 602 rotates, the sliding rod 604 is driven to slide toward the driving gear 602 through the rotating connecting rod 603, so that the pushing member 9 is located near the driving gear 602. At this time, the tennis ball can be unloaded through the structure of the shell 4 and the unloading component 5, so that the tennis ball is located in front of the pushing member 9 inside the launching shell 8. At this time, the rotating motor 601 is reversed. When the rotating motor 601 is reversed, the torsion spring assembly 607 simultaneously performs work externally, thereby accelerating the rotation speed of the driving gear 602 and the driven gear 606, thereby improving the launching speed of the tennis ball.

[0042] When the device is required to perform random angle serve, the position of the rotation connection point between the top of the driven gear 606 and the rotating connecting rod 603 is changed, so that when the driving gear 602 drives the driven gear 606 to transmit, the sliding positions of the two sets of sliding rods 604 are inconsistent, thereby causing the inclined push plate 7 to tilt, and the pushing member 9 is located in a tilted state inside the launching shell 8. When the above-mentioned launching steps are repeated, the pushing member 9 causes the tennis ball launching angle to change due to the tilt, thereby achieving the effect of launching the tennis ball at a random angle.

[0043] Example 2

[0044] like Figures 1-6 As shown, in order to solve the existing problems, based on the same concept as the above-mentioned embodiment 1, the ball throwing device further includes: the blanking component 5 includes a rotating blocking member 501 rotatably connected to the inner side wall of the shell 4, one end of the side of the rotating blocking member 501 is fixedly connected to a rotating shaft 504, the rotating shaft 504 passes through the side of the shell 4 and is rotatably connected to the side of the shell 4, the outer side of the shell 4 is connected to a rotating bracket 505, the rotating bracket 505 is rotatably connected to the adjusting screw 503, the outer side of the shell 4 is slidably connected to a damping member 502, the damping member 502 is threadedly connected to the adjusting screw 503, and the damping member 502 is in contact and extruded with the outer arc surfaces of the two rotating shafts 504;

[0045] Furthermore, a conical bucket is provided at the bottom of the shell 4 , the bottom of the conical bucket is through, and the conical bucket faces the direction of the launching shell 8 .

[0046] The specific working principle is: by rotating the adjusting screw 503, the damping member 502 can be made to rise and fall and slide outside the shell 4, and the damping member 502 squeezes the side of the rotating shaft 504 to control the size of the rotational resistance of the rotating shaft 504. The connection combination of the rotating shaft 504 and the rotating blocking member 501 can control the size of the rotational resistance of the rotating blocking member 501. Since the tennis ball falls from the center of the two rotating blocking members 501 under the guidance of the conical bucket, different rotational resistances of the rotating blocking member 501 can change the falling speed of the tennis ball, thereby realizing the control effect of the present device on the falling speed of the tennis ball inside the shell 4.

[0047] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
