Description

Technical Field

[0001] The utility model belongs to the technical field of basketball training, in particular to a basketball training ball serving device. Background Art

[0002] Basketball is a sport with high ornamental value and mass participation. Shooting is the most important way to score in basketball games. Athletes need a lot of shooting practice to improve their hit rate. Traditional shooting training is divided into self-shooting and self-rebounding type and sparring and auxiliary type. Self-shooting and self-rebounding type wastes time and energy to pick up the ball, while sparring and auxiliary type cannot practice by oneself, wasting human resources, so basketball training machines came into being.

[0003] The patent document with publication number CN117065309A discloses a basketball training transmitter, comprising: a mobile vehicle; a lifting mechanism, wherein the lifting mechanisms are two and the two lifting mechanisms are respectively arranged on the left and right sides of the upper end of the mobile vehicle; a ground pass serving mechanism, wherein the ground pass serving mechanism is arranged above the lifting mechanism on the right; a high pass serving mechanism, wherein the high pass serving mechanism is arranged above the lifting mechanism on the left; and a basketball collecting mechanism, wherein the basketball collecting mechanism is arranged at a rear position on the upper surface of the mobile vehicle. The basketball training transmitter of the present invention can realize simulated serving at various angles at various heights, so that basketball players can simulate receiving the ball at various angles during training, which greatly improves the training effect of basketball players.

[0004] The above-mentioned comparative document cannot be used in conjunction with an ordinary basketball stand, and can only be used for random serving and receiving training. Moreover, the height of its collecting mechanism is different from that of a conventional basket, and conventional pitching training cannot be performed. Utility Model Content

[0005] The purpose of the utility model is to provide a basketball training serving device to solve the problems mentioned in the above background technology.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] The yoke is provided with a plurality of cams, each of which ...

[0008] Furthermore, the net hanging assembly includes: a first telescopic rod, a second telescopic rod, a corner bracket, a bottom hook, and a top hook. The number of the first telescopic rods is two groups. The two groups of first telescopic rods are fixed in an inclined state on the side of the upper bracket close to the hanging bracket. A corner bracket is fixed at each of the two top corners on the side of the upper bracket away from the hanging bracket. The second telescopic rod is fixed on the corner bracket. A top hook is fixed to the telescopic end of the first telescopic rod and the second telescopic rod. A plurality of bottom hooks are fixed on the upper bracket. The top hook and the bottom hook jointly unfold and hang the ball catching net. A notch will be formed at the bottom of the ball catching net after hanging. The notch is located directly above the rotating bracket.

[0009] Furthermore, in order to allow the basketball to have a relatively stable waiting position for launching before launching, two sets of ball storage racks with folding rod structures are provided on the ring frame and vertical rods of the rotating frame, and the middle parts of the two sets of ball storage racks are bent downward to form ball storage positions. The positions of the ball storage positions must meet the requirements that when the basketball is located in the ball storage positions, the outer surface of the basketball contacts the launching wheel, and in the absence of external force, the basketball will be temporarily stored in the ball storage position due to gravity.

[0010] Furthermore, in order to ensure that the ball caught by the ball receiving net falls accurately on the ball storage rack, a guide frame with an inclined rod structure is provided on both sides above the ball storage rack. The two groups of guide frames are distributed outward from top to bottom and tilted downward from top to bottom. The maximum horizontal distance of the guide frames is greater than the diameter of the basketball.

[0011] Furthermore, in order to enable the deflection machine to have driving deflection capability, the deflection machine is a steering gear or a rotating motor with a reducer, and the connecting flange is fixedly coaxially connected to the output shaft of the steering gear or the reducer output shaft of the rotating motor with a reducer.

[0012] Furthermore, in order to protect the deflection machine, the lower bracket also includes: a protective shell, the protective shell cover is fixed under the lower frame, a battery and a controller are fixed in the protective shell, the battery is a rechargeable battery, the battery supplies power to the controller, and the controller and the deflection machine and the two sets of motors are electrically connected through wires.

[0013] Furthermore, in order to make the initial velocity of the basketball more stable when it is launched, the launching wheels are made of elastic material, the minimum distance between the two launching wheels is smaller than the diameter of the basketball, and the wheel surface of the launching wheels is provided with convex or concave anti-slip patterns; when launching the basketball, the two launching wheels will produce elastic deformation to increase the extrusion force, thereby increasing the friction between the launching wheels and the basketball.

[0014] Furthermore, for easy storage, the lower end of the bracket is connected to the upper bracket by a hinge. When the utility model is not in use, the bracket can be rotated and stored by the hinge, and then the ball receiving net can be removed and all the first telescopic rods and the second telescopic rods can be shortened to reduce the volume occupied by the utility model.

[0015] In summary, the utility model has the following beneficial effects:

[0016] The basketball hoop can be used in conjunction with an ordinary basketball stand, and can be used not only for catching but also for throwing training: by setting up a hanging rack, a rotating rack, and a hanging net assembly, the hanging rack is used to mount the utility model on the basket as a whole, and the first telescopic rods on both sides will be supported against the backboard to form a fulcrum. During basketball training, the basketball thrown near the basket will be collected by the catching net and enter the rotating rack from the notch below the catching net. After the basketball enters the rotating rack, it will be received by the inclined guide rack under the action of gravity and guided downward for transportation. Because the guide rack is distributed outward from top to bottom, and the horizontal maximum distance of the guide rack is greater than the diameter of the basketball, the basketball will lose support and fall from the guide rack to the ball storage rack when it moves to the horizontal maximum distance of the guide rack. In the absence of external force, the basketball will be temporarily stored in the lowest point of the ball storage rack, that is, the ball storage position, waiting for launch due to gravity. When the basketball needs to be launched, the controller controls the deflection machine to drive the connecting flange to rotate. Because the connecting flange is connected to the connecting plate, the connecting flange will drive the rotating rack to deflect as a whole. After deflection, the controller starts the two motors to rotate synchronously, and the two motors The rotation directions of the machine are opposite. When the two motors rotate, the launching wheels thereon will be driven to rotate, because the minimum distance between the two launching wheels is less than the diameter of the basketball, and the wheel surface of the launching wheel is provided with convex or concave anti-slip patterns; when launching the basketball, the two launching wheels will produce elastic deformation to increase the squeezing pressure, thereby increasing the friction between the launching wheels and the basketball. Under the blessing of high friction, when the launching wheel is separated from the basketball, the rotating launching wheel will give the basketball an outward thrust, thereby sending the basketball out. The sent basketball is caught by the training personnel and a shooting action is performed. The basketball thrown near the basket will be collected by the catching net. The above actions are repeated to complete multiple trainings. By programming the controller, the deflection angle of the deflector can be made random each time, so that the random angle catching and throwing ability of the basketball player can be trained. By programming the controller, the rotation speed of the two sets of motors can be made random, so the distance of the basketball launch will also change randomly, so that the random straight-line distance catching and throwing ability of the basketball player can be trained. The combination of the two can train the catching and throwing ability of the basketball player in a certain area. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] Example:

[0027] See also Figure 1-Figure 7 The utility model provides a technical solution: a basketball training serve, comprising: an upper bracket 1 and a lower bracket 2; the upper bracket 1 is a square frame structure, one end of the upper bracket 1 is connected to the lower bracket 2 through a connecting frame 7 of a tubular structure, under the connection of the connecting frame 7, a notch is formed between the upper bracket 1 and the lower bracket 2, and a rotating frame 4 is rotatably matched in the notch, and the main body of the rotating frame 4 is two groups of annular ring frames 41, and the two ring frames 41 are fixed in parallel by vertical rods 42, and a connecting plate 45 of a plate structure is fixed on the lower ring frame 41, and the main body of the lower bracket 2 is a The lower frame 21 has a square structure, and the lower frame 21 is connected to a deflection machine 9 through a connecting plate. The rotating shaft of the deflection machine 9 is fixedly connected through a connecting flange 10 and a connecting plate 45. The outer circumferential surface of the connecting flange 10 and the connecting plate on the frame 21 are rotatably matched. A motor 6 is fixed to each side of the connecting plate 45 through a motor bracket. A launching wheel 8 is fixedly matched on the output shaft of each group of motors 6. The upper bracket 1 is provided with a hanging bracket 3 for hanging the upper bracket 1 on the basket 15, as well as a hanging net assembly 5 and a ball receiving net 11 for facilitating the basketball 14 to enter the rotating frame 4.

[0028] The net hanging assembly 5 includes: a first telescopic rod 51, a second telescopic rod 52, a corner bracket 53, a bottom hook 54, and a top hook 55. The number of the first telescopic rod 51 is two groups. The two groups of first telescopic rods 51 are fixed in an inclined state on the side of the upper bracket 1 close to the hanging bracket 3. A corner bracket 53 is fixed at each of the two top corners of the side of the upper bracket 1 away from the hanging bracket 3. The second telescopic rod 52 is fixed on the corner bracket 53. The telescopic ends of the first telescopic rod 51 and the second telescopic rod 52 are each fixed with a top hook 55. A plurality of bottom hooks 54 are fixed on the upper bracket 1. The top hook 55 and the bottom hook 54 jointly unfold and mount the ball receiving net 11. A notch will be formed at the bottom of the mounted ball receiving net 11, and the notch is located directly above the rotating frame 4.

[0029] Two sets of ball storage racks 44 with folding rod structures are provided on the ring frame 41 and the vertical rod 42 of the rotating frame 4. The middle parts of the two sets of ball storage racks 44 are bent downward to form ball storage positions 46. The positions of the ball storage positions 46 must meet the requirements that when the basketball 12 is located in the ball storage positions 46, the outer surface of the basketball 12 contacts the launching wheel 8. In the absence of external force, the basketball will be temporarily stored in the ball storage position 46 due to gravity.

[0030] A guide frame 43 with an inclined rod structure is respectively provided on both sides above the ball storage rack 44 . The two groups of guide frames 43 are distributed outwardly from top to bottom and tilted downward from top to bottom. The farthest horizontal distance of the guide frames 43 is greater than the diameter of the basketball 12 .

[0031] The deflection gear 9 is a steering gear or a rotary motor with a reducer, and the connecting flange 10 is fixedly coaxially connected to the output shaft of the steering gear or the output shaft of the rotary motor with a reducer.

[0032] The lower bracket 2 also includes: a protective shell 22, the protective shell 22 cover is fixed under the lower frame 21, and a battery and a controller are fixed in the protective shell 22. The battery is a rechargeable battery, and the battery supplies power to the controller. The controller and the deflection machine 9 and the two sets of motors 6 are electrically connected through wires.

[0033] The launching wheels 8 are made of elastic material, the minimum distance between the two launching wheels 8 is smaller than the diameter of the basketball 12, and the wheel surface of the launching wheels 8 is provided with convex or concave anti-slip patterns; when the basketball 12 is launched, the two launching wheels 8 will produce elastic deformation to increase the squeezing force, thereby increasing the friction between the launching wheels 8 and the basketball 12.

[0034] The lower end of the hanger 3 is connected to the upper bracket 1 through a hinge. When the utility model is not in use, the hanger 3 can be rotated and retracted through the hinge, and then the ball receiving net 11 is removed and all the first telescopic rods 51 and the second telescopic rods 52 are shortened to reduce the volume occupied by the utility model.

[0035] When using, Figure 5As shown, the utility model is mounted on the basket 15 as a whole by using the hanger 3, and the first telescopic rods 51 on both sides will be supported against the backboard 14 to form a fulcrum. During basketball training, the basketball 12 thrown near the basket 15 will be collected by the ball receiving net 11 and enter the rotating frame 4 from the notch below the ball receiving net 11. After the basketball 12 enters the rotating frame 4, it will be received by the inclined guide frame 43 under the action of gravity and guided downward for transportation. Because the guide frame 43 is distributed outwardly from top to bottom, and the horizontal maximum distance of the guide frame 43 is greater than the diameter of the basketball 12, the basketball 12 will lose support and fall from the guide frame 43 to the ball storage frame 44 when it moves to the horizontal maximum distance of the guide frame 43. In the absence of external force, the basketball will be temporarily stored in the ball storage frame 44 due to gravity. 4 is at the lowest point, that is, in the ball storage position 46 waiting for launching. When the basketball 12 needs to be launched, the controller controls the deflection machine 9 to drive the connecting flange 10 to rotate. Because the connecting flange 10 is connected to the connecting plate 45, the connecting flange 10 will drive the rotating frame 4 to deflect as a whole. After deflection, the controller starts the two motors 6 to rotate synchronously. The rotation directions of the two motors 6 are opposite (the rotation directions of the two motors 6 are both the directions of pushing the basketball 12 to be launched through the launching wheel 8, so the rotation directions of the two motors 6 will be opposite to each other). When the two motors 6 rotate, they will drive the launching wheels 8 thereon to rotate, because the minimum distance between the two launching wheels 8 is less than the diameter of the basketball 12, and the wheel surface of the launching wheel 8 is provided with convex or concave anti-slip patterns; when launching the basketball 12 When the two launching wheels 8 are in a state of being elastically deformed to increase the squeezing force, the friction between the launching wheels 8 and the basketball 12 is increased. Under the high friction, when the launching wheels 8 are separated from the basketball 12, the rotating launching wheels 8 will give the basketball 12 an outward thrust, thereby sending the basketball 12 out. The sent basketball 12 is caught by the training personnel (basketball player) and a shooting action is performed. The basketball 12 thrown near the basket 15 will be collected by the receiving net 11. The above actions are repeated to complete multiple trainings. By programming the controller, the deflection angle of the deflection machine 9 can be made random each time, so as to train the basketball player's ability to catch and shoot the ball at random angles. By programming the controller, the rotation speed of the two sets of motors 6 can be made random, so that the distance of the basketball 12 launched is also random. By changing the machine, the basketball player's ability to catch and throw the ball at random straight-line distances can be trained. The combination of the two can train the basketball player's ability to catch and throw the ball within a certain area. After the training is completed, the utility model can be removed as a whole through the hanger 3. When the utility model is not in use, the hanger 3 can be rotated and stored through the hinge, and then the ball receiving net 11 can be removed and all the first telescopic rods 51 and the second telescopic rods 52 can be shortened to reduce the volume occupied by the utility model and facilitate the storage of the utility model (the controller is made of an existing development board and program, and its control principle and control structure are not within the protection scope of this application, so they are not repeated). At the same time, the utility model can also store more than one basketball in the ball receiving net to improve the training intensity of basketball catching and throwing abilities.
