Description

Technical Field

[0001] The invention relates to the technical field of basketball training equipment, in particular to a basketball training jammer. Background Art

[0002] A basketball training jammer is a device that assists basketball training. It is a training device that simulates the opponent's defensive interference scene in the game. It aims to create a training environment closer to actual combat for players and help them improve their technical level and coping ability under defensive pressure. Shooting jammers are mainly used for shooting training. Usually, there is a device that simulates the defensive player's arm, which swings up and down or left and right when the player shoots, interfering with the player's sight and shooting action. Basketball training jammers can improve the stability of technical movements, enhance psychological stress resistance, and improve reaction speed and adaptability.

[0003] In the prior art, there is a basketball training jammer that interferes with shooting. In common basketball training, two human arms are generally manufactured in one piece, so that the human arms maintain a certain posture, or the human arms are fixed to a human model with pin holes, so that the posture of the human arms is relatively simple. Athletes cannot swing their arms repeatedly during training. The limited posture of the human arms is not very helpful for basketball training. The bottom of the human model is generally supported by a jammer base, or the human model uses a fixed leg support. The basketball training jammer cannot imitate the lower body posture of the athlete when blocking the ball. Summary of the invention

DETAILED DESCRIPTION

[0033] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] See also Figure 1 - Figure 3As shown, a basketball training interferer includes an interferer base 1, a human model 2, and two human arms 4. The human model 2 is arranged at the top of the interferer base 1 and is supported by the interferer base 1. During basketball training, the human model 2 can be used to imitate the human torso to interfere with the dribbler's dribbling. And the two human arms 4 are arranged at the upper two corners of the human model 2, and the two human arms 4 are used to imitate the human arms to interfere with the dribbler's dribbling. A fixed cavity is opened inside the human model 2, and a fixing plate 3 is installed at the rear end of the human model 2 and at the position of the fixed cavity. The fixing plate 3 can be installed at the rear end of the human model 2, so that each component of the arm swing structure 5 can be installed inside the fixed cavity. An arm swing structure 5 is arranged inside the fixed cavity. The arm swing structure 5 includes two reserved slots 51. The two reserved slots 51 are opened at the upper two corners of the human arm 4. The two reserved slots 51 are communicated with the inside of the fixed cavity of the human model 2. The two human arms 4 are respectively arranged inside the two reserved slots 51. At the ends of the two human arms 4 and inside the reserved slots 51, a first gear 52 and a second gear 53 are integrally arranged respectively. An asynchronous motor 56 is installed on the end face of the human model 2 and at the position of the first gear 52. The output end of the asynchronous motor 56 is connected to the first gear 52. The asynchronous motor 56 is used to drive the first gear 52 to rotate back and forth. The asynchronous motor 56 can rotate forward and backward to drive the first gear 52 to rotate, so as to drive the human arm 4 at the position of the first gear 52 to swing back and forth. Also, the swing frequency of the two human arms 4 can be adjusted according to the rotation speed of the asynchronous motor 56. A third gear 54 and a fourth gear 55 are arranged between the first gear 52 and the second gear 53. Both the first gear 52 and the second gear 53 are rotatably connected inside the reserved slot 51. The third gear 54 and the fourth gear 55 are used to drive the two human arms 4 to swing repeatedly. The first gear 52 drives the third gear 54, the fourth gear 55, and the second gear 53 to rotate. The two sets of gears cause the human arm 4 of the second gear 53 to swing. Thus, the rotation of the first gear 52 of one human arm 4 can drive the rotation of the second gear 53 of the other human arm 4.

[0036] Please refer to Figure 3 As shown, a first rotating shaft 57 is arranged in the middle of the third gear 54. The third gear 54 is rotatably connected to the first rotating shaft 57. A second rotating shaft 58 is arranged in the middle of the fourth gear 55. The fourth gear 55 is rotatably connected to the second rotating shaft 58. Both the first rotating shaft 57 and the second rotating shaft 58 are horizontally arranged inside the human model 2. The two ends of the first rotating shaft 57 and the two ends of the second rotating shaft 58 can be arranged between the human model 2 and the fixing plate 3, so as to ensure that the third gear 54 can rotate on the first rotating shaft 57 and the fourth gear 55 can rotate on the second rotating shaft 58.

[0037] Please refer to Figure 2 andFigure 3 As shown, the first gear 52, the third gear 54, the fourth gear 55 and the second gear 53 are meshed in sequence. Two human arms 4 rotate in opposite directions around the axes of their respective first gears 52 and second gears 53. The first gear 52, the third gear 54, the fourth gear 55 and the second gear 53 are meshed, so that power can be transmitted to the second gear 53. The two human arms 4 swing in opposite directions, causing one human arm 4 to swing upward and the other human arm 4 to swing downward. During basketball training, the two human arms 4 can be used to imitate the up-and-down swing of a person's arm to interfere with the dribbler's dribbling.

[0038] Please refer to Figure 1 、 Figure 4 - Figure 7 As shown, an adjustment structure 6 is provided between the first gear 52 and the second gear 53. The arm swing structure 5 includes a fixing frame 61. The shape of the fixing frame 61 is triangular. The first rotating shaft 57 and the second rotating shaft 58 are respectively welded to two vertex angles of the fixing frame 61, and a third rotating shaft 63 is welded inside the third vertex angle of the fixing frame 61. A fifth gear 62 is rotatably connected to the end of the third rotating shaft 63 and corresponding to the fourth gear 55. The fixing frame 61 can be used to initially fix the third gear 54, the fourth gear 55 and the fifth gear 62, so that the third gear 54, the fourth gear 55 and the fifth gear 62 are meshed. The fifth gear 62 is meshed with the fourth gear 55. The whole fixing frame 61 rotates around the output end axis of the fourth gear 55. The fixing frame 61 can drive each of the third gear 54, the fourth gear 55 and the fifth gear 62 around the output end axis of the asynchronous motor 56. One of the fourth gear 55 or the fifth gear 62 can be meshed with the second gear 53. The fourth gear 55 is meshed with the second gear 53, so that the two human arms 4 swing in opposite directions; the fifth gear 62 is meshed with the second gear 53, so that the two human arms 4 swing in the same direction. The second gear 53 is only meshed with the fifth gear 62 to drive the two human arms 4 to swing in the same direction.

[0039] Please refer to Figure 5As shown, three sets of sliding grooves 66 are formed on the inner wall of the fixing cavity of the mannequin 2. The shapes of the three sets of sliding grooves 66 are arc-shaped, and the central angles of the three sets of sliding grooves 66 are the same. The centers of the three sets of sliding grooves 66 correspond to the axis of the output end of the asynchronous motor 56. The three sliding grooves 66 are concentric arcs, so that the first rotating shaft 57, the second rotating shaft 58 and the third rotating shaft 63 move. Sliding blocks 67 are welded to the ends of the first rotating shaft 57, the second rotating shaft 58 and the third rotating shaft 63. The three sliding blocks 67 are respectively slidably connected to the sliding grooves 66. The fixing frame 61 synchronously rotates the third gear 54, the fourth gear 55 and the fifth gear 62 around the axis of the first gear 52. The rotating fixing frame 61 can separate the fourth gear 55 from the second gear 53 and then mesh the fifth gear 62 with the second gear 53, so that the two human arms 4 on the first gear 52 and the second gear 53 swing in the same direction.

[0040] Please refer to Figure 6 and Figure 7 As shown, threaded rods 64 and knobs 65 that are fixed to each other are threadedly connected to the first rotating shaft 57, the second rotating shaft 58 and the third rotating shaft 63. By rotating each knob 65, the corresponding threaded rod 64 can be driven to rotate. Guide grooves 610 are formed on the cylindrical surfaces of the three threaded rods 64. By rotating the threaded rod 64, the position of the guide groove 610 is adjusted. Matching grooves 68 are formed on the surface of the fixing plate 3 and at the positions of the three threaded rods 64. The shapes of the three matching grooves 68 are arc-shaped, so that the threaded rod 64 can move along the matching groove 68. The center of the arc of the matching groove 68 is adapted to the axis of the output end of the asynchronous motor 56. Guide bars 69 are provided on the inner walls of the three matching grooves 68. By rotating the threaded rod 64, the guide groove 610 is adjusted to the position of the guide bar 69, so that the guide groove 610 of the threaded rod 64 can slide along the guide bar 69, and thus the gears on the fixing frame 61 move, so that one of the fourth gear 55 and the fifth gear 62 is meshed with the second gear 53.

[0041] Please refer to Figure 6 and Figure 7 As shown, the clearance between the guide bar 69 of the same matching groove 68 is adapted to the inner diameter of the guide groove 610. The guide groove 610 is slidably connected to the guide bar 69. The diameter of the smooth section of the threaded rod 64 is adapted to the fillets at both ends of the matching groove 68. The smooth section of the threaded rod 64 is rotatably connected to the fillets at both ends of the matching groove 68. When the threaded rod 64 is located at the top position of the matching groove 68, only the fourth gear 55 can be meshed with the second gear 53. When the threaded rod 64 is located at the bottom position of the matching groove 68, only the fifth gear 62 can be meshed with the second gear 53.

[0042] Please refer to Figure 1 , Figure 8 and Figure 9As shown, a leg interference device 7 is provided at the bottom corner of the mannequin 2. The leg interference device 7 includes a first connecting bar 74 and a second connecting bar 75. The first connecting bar 74 and the second connecting bar 75 are respectively rotatably connected to the inside of the bottom end of the mannequin 2. A sixth gear 71 is welded in the middle of the first connecting bar 74, and a seventh gear 72 is welded in the middle of the second connecting bar 75. Human legs 76 are provided at the bottom ends of the first connecting bar 74 and the second connecting bar 75. The first connecting bar 74 and the second connecting bar 75 can rotate around the inside of the bottom end of the mannequin 2, so as to rotate the sixth gear 71 of the first connecting bar 74, the second connecting bar 75 and the seventh gear 72, so as to swing the first connecting bar 74 and the second connecting bar 75. Thus, the two human legs 76 at the bottom ends of the first connecting bar 74 and the second connecting bar 75 swing. Therefore, when training basketball, the mannequin 2 can be used to imitate the legs of a person to interfere with the dribbler's dribbling. Intermediate pins, swing grooves 77 and connecting pins are provided at the bottom ends of the first connecting bar 74 and the second connecting bar 75. The connecting pins are slidably connected to the inside of the swing grooves 77. The human legs 76 are rotatably connected to the intermediate pins. When the first connecting bar 74 and the second connecting bar 75 swing, they will drive the two human legs 76 to approach or move away from each other, and the connecting pins and the swing grooves 77 can be used for sliding, so as to limit the positions of the two human legs 76. Two eighth gears 73 are provided between the sixth gear 71 and the seventh gear 72, and the sixth gear 71, the two eighth gears 73 and the seventh gear 72 are meshed in sequence. When the sixth gear 71 rotates, it will drive the two eighth gears 73 and the seventh gear 72 to mesh. The rotation directions of the sixth gear 71 and the seventh gear 72 are opposite, so as to arrange the two human legs 76 in a "horse stance" posture. The top ends of the first connecting bar 74 and the second connecting bar 75 intersect at one point, and an intermediate rod 711 is provided at the intersection of the first connecting bar 74 and the second connecting bar 75. Floating grooves 712 are provided at the ends of the first connecting bar 74 and the second connecting bar 75 where the intermediate rod 711 is located, and the two floating grooves 712 are movably connected to the intermediate rod 711. The openings of the first connecting bar 74 and the second connecting bar 75 that swing in opposite directions become larger or smaller, and the intermediate rod 711 floats between the two floating grooves 712. The two second connecting bars 75 are used to drive the two human legs 76 to swing in opposite directions.

[0043] Please refer to Figure 8 and Figure 9As shown, two toggle levers 710 are welded to the end face of the fifth gear 62. When the fifth gear 62 rotates, the toggle levers 710 can be swung. A threaded telescopic rod 78 is welded to the end of the first connecting bar 74. The threaded telescopic rod 78 is used to adjust the length of the threaded telescopic rod 78 extending out. The end of the threaded telescopic rod 78 is in contact with the toggle lever 710. The two toggle levers 710 are used to toggle the toggle lever 710 and the first connecting bar 74 to swing around the axis of the sixth gear 71. The toggle lever 710 of the rotating fifth gear 62 swings, so that the toggle lever 710 toggles the extended threaded telescopic rod 78. The mating groove 68 and the first connecting bar 74 swing around the axis of the sixth gear 71, so as to swing the first connecting bar 74. The swinging first connecting bar 74 drives the sixth gear 71, the two boxes of eighth gears 73 and the seventh gear 72 to mesh. The seventh gear 72 drives the second connecting bar 75 to swing, so that the two human legs 76 swing;

[0044] Only when the fourth gear 55 meshes with the second gear 53, the two human arms 4 swing in opposite directions. The rotation of the second gear 53 drives the toggle lever 710 to rotate. The toggle lever 710 can toggle the threaded telescopic rod 78 and the first connecting bar 74 to swing, so that the two human legs 76 open or close; Only when the fifth gear 62 meshes with the second gear 53, the two human arms 4 swing in the same direction. The rotation of the second gear 53 drives the toggle lever 710 to rotate. The toggle lever 710 can toggle the threaded telescopic rod 78 and the first connecting bar 74 to swing, so that the two human legs 76 open or close.

[0045] Please refer to Figure 9 As shown, two intermediate bars 79 are provided at the intersection of the first connecting bar 74 and the second connecting bar 75. The two intermediate bars 79 are respectively connected to the first connecting bar 74 and the second connecting bar 75. And the area surrounded by the first connecting bar 74, the second connecting bar 75 and the two intermediate bars 79 is a rhombus area. The intermediate bars 79 are used to ensure that the first connecting bar 74 and the second connecting bar 75 swing simultaneously. The first connecting bar 74, the second connecting bar 75 and the two intermediate bars 79 in the shape of a rhombus will cause the included angle between the first connecting bar 74 and the second connecting bar 75 to change, so as to adjust the distance between the two human legs 76 to change, and ensure that the two sliding grooves 66 approach or move away from each other simultaneously.
