DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] Reference Figure 1 ,exist Figure 1 In the figure, a points to the front view, and b points to the right view. The above views are only used to understand the plan.

[0027] Please refer to Figure 1-Figure 6 As shown, the present invention provides a soccer training device for physical education that can simulate the trajectory of a soccer ball, comprising a fixed suction cup 1 and an elastic rope 35, a connecting pillar 11 is fixedly installed at the top center of the fixed suction cup 1, a semicircular shell 2 is rotatably connected to the top of the connecting pillar 11, a rope outlet 21 is opened near the vertex on the outer side of the semicircular shell 2, and a fixed arc opening 22 is opened in the middle of the outer side of the semicircular shell 2;

[0028] The bottom inner wall of the semicircular shell 2 is provided with a winding mechanism for pulling the football to rebound quickly at multiple angles, and the elastic rope 35 is wound around the outside of the winding mechanism;

[0029] Please refer to Figure 2 and Figure 3As shown, the winding mechanism pulls the football back quickly through the elastic rope 35, and at the same time, the semi-circular arc shell 2 rotates so that the pulling direction of the football by the elastic rope 35 is constantly changing, so that the trajectory of the football is constantly changing when it rebounds. When pulling the football, the elastic rope 35 simulates the uncertain trajectory of the trainer kicking the ball, thereby increasing the training difficulty of the football players.

[0030] A wire arrangement mechanism is fixedly provided on one side of the winding mechanism so that the elastic cord 35 is evenly wound around the outer side of the winding mechanism when the football rebounds;

[0031] Please refer to Figure 2 and Figure 3 As shown, while the elastic rope 35 is quickly wound around the outside of the winding mechanism, the wire arrangement mechanism drives the elastic rope 35 to be evenly arranged outside the winding mechanism, thereby preventing the elastic rope 35 from being tangled when winding back and affecting the next training.

[0032] The arc-shaped inner wall of the semicircular arc housing 2 is fixedly provided with a friction mechanism for training players to kick the ball with different strengths;

[0033] Please refer to Figure 2 , Figure 4 and Figure 5 As shown, the elastic rope 35 is clamped by the friction mechanism to change the resistance of the elastic rope 35 passing through the friction mechanism, so as to adjust the resistance of the football when it flies out, thereby realizing the training of athletes for different kicking strengths.

[0034] An adjusting mechanism for adjusting the power of the friction mechanism is fixedly arranged on one side of the friction mechanism.

[0035] Please refer to Figure 2 and Figure 6 As shown, the friction force of the elastic rope 35 is adjusted by the friction mechanism by rotating the adjustment mechanism.

[0036] In the above scheme, one end of the elastic rope 35 is wound around the winding mechanism, and the other end is connected to the football, and the fixed suction cup 1 is fixed at a certain place. When the football player kicks the football during training, the elastic rope 35 pulls the football back and limits it from flying too far. At the same time, the friction strength of the friction mechanism on the elastic rope 35 can be adjusted by the adjustment mechanism, so that the athlete can train different kicking strengths. When the football is kicked, the maximum flying distance of the football is limited by the length of the elastic rope 35. At the same time, when returning the football, the winding mechanism returns the elastic rope 35 so that the elastic rope 35 is wound around the outside of the winding mechanism, and the winding mechanism drives the semi-elastic rope 35 to pull the football back. The arc shell 2 rotates, and the semi-arc shell 2 rotates so that the direction of the pulling force on the football by the winding mechanism through the elastic rope 35 is constantly changing, so that the trajectory of the football is constantly changing when it rebounds. When pulling the football, the elastic rope 35 simulates the uncertain trajectory of the trainer kicking the ball, thereby increasing the training difficulty of the football players. At the same time, when the elastic rope 35 is wound around the winding mechanism, the wire arrangement mechanism makes the elastic rope 35 evenly wound around the outside of the winding mechanism, preventing the elastic rope 35 from being wound in disorder when it is wound around the winding mechanism and affecting the next training. This enhances the effect of the football training device on the training effect of athletes to a certain extent.

[0037] Specifically, the winding mechanism includes a fixed plate 3, on which the bottom inner wall of the semicircular arc shell 2 is fixedly installed near the center of the circle, a driving motor 31 is fixedly installed on the right side of the fixed plate 3, the left end of the driving motor 31 penetrates the left side of the fixed plate 3 and extends out, and a driving gear 32 is fixedly installed on the output end of the driving motor 31 extending out of the left side of the fixed plate 3, a one-way bearing 33 is provided on the inner ring of the driving gear 32, the outer side of the one-way bearing 33 is fixedly installed with the inner wall of the driving gear 32, a rope collecting shaft 34 is fixedly installed on the inner ring of the one-way bearing 33, and an elastic rope 35 is wound around the outer side of the rope collecting shaft 34, a driven groove is provided at the bottom of the semicircular arc shell 2 near the center of the circle, and a driven gear 36 is rotatably connected to the inner wall of the driven groove near the center of the circle, and the driven gear 36 is meshed with the driving gear 32, and a fixed annular gear 37 is fixedly installed on the outer side of the connecting pillar 11 close to the top, and the driven gear 36 is meshed with the fixed annular gear 37.

[0038] In the above scheme, when the football needs to be returned, the driving motor 31 is started, the driving motor 31 drives the driving gear 32 to rotate, the driving gear 32 drives the inner and outer rings of the one-way bearing 33 to rotate, the inner ring of the one-way bearing 33 drives the rope collection shaft 34 to rotate, and when the rope collection shaft 34 rotates, the elastic rope 35 is pulled to quickly wrap around its outer side, and the elastic rope 35 is pulled by the pulling force of the rope collection shaft 34 to pull the football to return the ball quickly, and at the same time, the driving gear 32 drives the driven gear 36 to rotate, and the driven gear 36 drives the semi-circular arc shell 2 to rotate by meshing with the fixed annular gear 37. The rotation of the semi-circular arc shell 2 makes the rope collection shaft 34 constantly change the pulling direction of the football through the elastic rope 35, so that the trajectory of the football when rebounding is constantly changing, and the elastic rope 35 simulates the uncertain trajectory of the trainer kicking the ball when pulling the football, thereby increasing the training difficulty of the football players.

[0039] When the football drives the elastic rope 35 to release the line, the rope collection shaft 34 rotates due to the pulling force of the elastic rope 35. At this time, the rope collection shaft 34 drives the inner ring of the one-way bearing 33 to rotate, and the outer ring of the one-way bearing 33 remains stationary.

[0040] Specifically, the cable arrangement mechanism includes a reciprocating screw 4, which is rotatably connected to the left side of the fixed plate 3, and is located on the upper front side of the driving gear 32. A power gear 41 is fixedly installed on the outer side of the reciprocating screw 4, and the power gear 41 is meshed with the driving gear 32. A reciprocating block 42 is threadedly connected to the outer side of the reciprocating screw 4, and a movable cable arrangement block 43 is fixedly installed on the rear side of the reciprocating block 42, and the elastic rope 35 passes through the movable cable arrangement block 43.

[0041] In the above scheme, when the football rebound elastic rope 35 is quickly wound around the rope collection shaft 34, the driving gear 32 drives the power gear 41 to rotate. When the power gear 41 rotates, it drives the reciprocating block 42 to move left and right under the restriction of the limit plate. The reciprocating block 42 drives the movable wire arrangement block 43 to move left and right. When the movable wire arrangement block 43 moves left and right, it drives the rope collection shaft 34 to rewind the elastic rope 35. The elastic rope 35 can be evenly arranged on the outside of the rope collection shaft 34, thereby preventing the elastic rope 35 from being tangled when it is winding back and affecting the next training.

[0042] Specifically, the friction mechanism includes a positioning connecting plate 5, which is fixedly mounted on the inner wall of the arc surface of the semicircular arc shell 2. A fixed annular plate 51 is fixedly mounted close to the bottom end of the positioning connecting plate 5 away from the center of the circle. A horizontal card slot 52 is provided on the top of the fixed annular plate 51. A horizontal card block 53 is slidably engaged with the horizontal card slot 52. A clamping plate 54 is fixedly mounted on the side close to the center of the circle. A rubber friction pad 55 is fixedly mounted on the side close to the center of the circle of the clamping plate 54. The rubber friction pad 55 is located in the inner ring of the fixed annular plate 51. A power-assisting cylindrical rod 56 is fixedly installed on the top of the horizontal block 53, a circular groove 57 is opened at the top of the fixed circular ring plate 51 away from the center of the circle, and an arc block is movably connected to the circular groove 57, and a power circular ring plate 58 is fixedly installed on the top of the arc block, and an arc power groove 59 is opened on the top of the power circular ring plate 58. The power-assisting cylindrical rod 56 is movably connected to the arc power groove 59, and the elastic rope 35 passes through the fixed circular ring plate 51 and the inner ring of the power circular ring plate 58, and the elastic rope 35 passes through the semi-circular arc shell 2 from the rope outlet 21.

[0043] In the above scheme, when the football player needs to train the kicking strength, the power annular plate 58 is rotated through the adjustment mechanism, and the power annular plate 58 is rotated along the annular slot 57 through the arc block, and the power annular plate 58 drives the arc power slot 59 to rotate, and the rotation of the arc power slot 59 drives the power-assisting cylindrical rod 56 to move toward a position close to the center of the circle, and the power-assisting cylindrical rod 56 drives the horizontal block 53 to move toward a position close to the center of the circle along the horizontal slot 52, and the horizontal block 53 drives the clamping plate 54 to move toward a position close to the center of the circle, and the clamping plate 54 drives the rubber friction pad 55 to move toward a position close to the center of the circle. Similarly, the working principle of the remaining rubber friction pads 55 is the same as above, and the elastic rope 35 is clamped by moving the plurality of rubber friction pads 55 toward a position close to the center of the circle, thereby increasing the resistance of the elastic rope 35 when passing through the fixed annular plate 51, and the friction force on the fixed annular plate 51 is increased by clamping the elastic rope 35 to adjust the resistance when the football flies out, thereby realizing the training of athletes for different kicking strengths.

[0044] Specifically, the adjustment mechanism includes a mounting plate 6, which is fixedly mounted on the outer side of the fixed annular plate 51, a connecting slot body 61 is fixedly mounted on the end of the mounting plate 6 away from the center of the circle, an auxiliary block 62 is movably connected to the connecting slot body 61, a pressing spring 63 is fixedly mounted on the top inner wall of the connecting slot body 61, the bottom end of the pressing spring 63 is fixedly mounted on the top of the auxiliary block 62, a grip plate 64 is fixedly mounted on the left end of the auxiliary block 62, the left end of the grip plate 64 extends out of the semicircular arc shell 2 from the fixed arc opening 22, and a fixed arc tooth 65 is fixedly mounted on the bottom of the grip plate 64.

[0045] When the athlete's kicking force needs to be adjusted, the grip plate 64 is held and lifted upward, and the grip plate 64 drives the fixed arc tooth 65 to move upward, and the fixed arc tooth 65 moves upward to release the meshing with the adjusting circular arc tooth. At the same time, the fixed arc tooth 65 drives the auxiliary clamping block 62 to move upward, and the auxiliary clamping block 62 moves upward to compress the pressing spring 63. At this time, the friction force of the friction mechanism on the elastic rope 35 can be rotated and adjusted by the grip plate 64. When the grip plate 64 is rotated to a certain angle, the friction mechanism adjusts the friction force on the elastic rope 35, and the grip plate 64 is released. At this time, the pressing spring 63 generates a rebound thrust to push the auxiliary clamping block 62 to move downward, and the auxiliary clamping block 62 drives the grip plate 64 to move downward, and the grip plate 64 drives the fixed arc tooth 65 to move downward and mesh with the adjusting circular arc tooth. The grip plate 64 is fixed by the engagement of the fixed arc tooth 65 with the adjusting circular arc tooth, thereby realizing the fixation of the friction force of the friction mechanism on the elastic rope 35.

[0046] Specifically, a receiving hole 7 is provided at the top of the outer side of the semicircular shell 2 .

[0047] In the above solution, when the athlete is not training, the football can be placed in the storage hole 7, so that the football can be placed easily.

[0048] Specifically, a counterweight 8 is fixedly mounted on the bottom inner wall of the semicircular arc housing 2 and located at a position symmetrical to the winding mechanism.

[0049] In the above scheme, the counterweight block 8 is used to increase the stability of the semicircular arc shell 2 during rotation, thereby preventing the semicircular arc shell 2 from deflecting during rotation and causing the entire football training device to fall over.

[0050] Specifically, a limiting plate is fixedly installed on the front side of the fixed plate 3 near the top, and the front side of the reciprocating block 42 is in contact with the rear side of the limiting plate.

[0051] In the above solution, the reciprocating block 42 is restricted by the limiting plate during the rotation of the reciprocating screw 4, so that the reciprocating block 42 moves.

[0052] Specifically, the center of the reciprocating thread groove on the outer side of the reciprocating screw 4 is in the same plane as the center of the rope collecting shaft 34 , and the length of the reciprocating thread groove is shorter than the length of the rope collecting shaft 34 .

[0053] In the above scheme, the distance that the reciprocating screw 4 moves back and forth through the reciprocating block 42 is smaller than the length of the rope collecting shaft 34, thereby preventing the elastic rope 35 from being wound around the one-way bearing 33 during the process of being wound around the outside of the rope collecting shaft 34.

[0054] Specifically, an adjusting circular arc tooth is fixedly installed on the bottom inner wall of the fixed arc opening 22 , and the adjusting circular arc tooth is meshed with the fixed arc tooth 65 .

[0055] In the above solution, the fixing of the gripping plate 64 is achieved by meshing the fixed arc teeth 65 with the adjusting circular arc teeth, thereby achieving the fixing of the friction force of the elastic rope 35 by the friction mechanism.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
