Description

Technical Field

[0001] This utility model relates to the field of sports training technology, and in particular to a ball-passing training device for volleyball training. Background Technology

[0002] Volleyball, a sport that combines speed, power, skill, and teamwork, enjoys extremely high participation and spectator appeal worldwide. Among the basic skills of volleyball, setting (or passing) is an indispensable element. It not only serves as a bridge connecting offense and defense but is also a crucial means of organizing attacks and adjusting the ball's trajectory during a match. Therefore, the quality of setting technique often directly impacts a team's overall performance and the outcome of a match. Currently, when training setting, athletes typically use a volleyball directly. This method fails to develop the athlete's arm strength or allow them to properly control the force of the pass, resulting in poor training effectiveness. Utility Model Content

[0003] The purpose of this invention is to provide a volleyball passing training device that can conveniently provide arm strength training for athletes during passing training, and can easily adjust the training intensity to improve training effect.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A volleyball training device for passing and setting includes a support frame, an outer shell inside the support frame, a rope threading opening on one side of the upper end of the outer shell, a lifting device at the end of the support frame away from the rope threading opening, a connecting rod horizontally arranged at the upper end of the lifting device, a horizontally arranged limiting slide rod rotatably connected to the lower end of the connecting rod away from the lifting device, a sliding sleeve movably connected to the outer side of the limiting slide rod, a connecting rope arranged on the outer side of the sliding sleeve, and a volleyball arranged at the free end of the connecting rope.

[0006] The housing is rotatably connected to a horizontally arranged rotating shaft inside. Multiple gears are rotatably connected to the outside of the rotating shaft at equal intervals. Each gear has a spring that is always in a compressed state inside. One end of each spring is connected to the rotating shaft, and the other end of each spring is connected to the corresponding gear. A worm gear is arranged on the outside of the rotating shaft. A horizontally arranged worm gear is rotatably connected to the inside of the housing near the worm gear.

[0007] Inside the housing, a limit shaft is vertically arranged near each gear. Inside the housing, a horizontally arranged pull rod is slidably connected to each limit shaft. At the lower end of the pull rod, multiple racks are vertically arranged and slidably connected to each pull rod, and each rack meshes with a corresponding gear. At the upper end of the pull rod, a pull rope is provided with one end extending out of the rope-threading opening. At the end of the pull rope extending out of the rope-threading opening, multiple elastic retaining sleeves are arranged at equal intervals.

[0008] By adopting the above technical solution, during use, the athlete secures the elastic sleeve to their wrist. By adjusting the lifting device, the connecting rod moves up and down, adjusting the height of the volleyball to facilitate training for people of different heights. Then, the athlete puts their hands together, raises the volleyball, and trains. During training, pulling the rope causes the pull rod to slide relative to the limit shaft, which in turn causes the rack to slide relative to the limit shaft. The rack drives the gear to rotate. Due to the action of the worm gear and worm, the rotation of the gear does not drive the shaft to rotate. The rotation of the gear causes the spring to compress, generating elasticity and providing resistance during training, thereby training the athlete's arm strength. After the ball rests and falls, the volleyball, through the pull rope, causes the sliding sleeve to slide relative to the limiting slide rod, and at the same time, it causes the limiting slide rod to rotate relative to the connecting rod, making it convenient for athletes to practice passing the volleyball falling from different directions. By rotating the worm gear, the worm gear drives the worm wheel to rotate, the worm wheel drives the rotating shaft to rotate, and the rotating shaft drives the spring to compress or stretch, changing the resistance of the gear rotation when the rack moves upward, thereby changing the training intensity of the athlete's arm strength. Since the spring is initially in a compressed state, it can always generate elasticity, so the rack can always drive the rack to move downward, and the worm gear can drive the rotating shaft to rotate relative to the gear.

[0009] A further feature of this invention is that the lifting device includes a fixed sleeve rod vertically arranged at one end of the bracket away from the rope-threading opening, a first fixing port opened on the upper side of the fixed sleeve rod near the bracket, a fixed rod slidably connected inside the fixed sleeve rod, a plurality of second fixing ports equally spaced at one end of the fixed rod near the bracket, a fixed frame slidably connected to the outside of the fixed sleeve rod near the first fixing port, a fixing block slidably connected to the fixed frame at one end near the first fixing port and slidably connected to each of the second fixing ports, and a plurality of springs equally spaced between the end of the fixed sleeve rod away from the first fixing port and the fixed frame.

[0010] A further feature of this invention is that a knob is provided at one end of the worm gear extending out of the outer casing.

[0011] A further feature of this invention is that a roller is rotatably connected to the upper end of the bracket near the rope-threading opening, and the pull rope passes through the rope-threading opening and is slidably connected to the roller.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] Firstly, it facilitates strength training for athletes' arms during ball-passing exercises, while also allowing for easy adjustment of training intensity, enabling athletes to better control the force of their passes. During ball-passing training, athletes pull the rope, which moves the lever. Due to the worm gear, the lever drives the gear via a rack, which in turn compresses the spring, generating elasticity and providing resistance during training. This trains the athlete's arm strength. Secondly, it allows the worm to rotate, which in turn drives the shaft via a worm wheel. Since the spring is always initially compressed, the shaft can rotate relative to the gear, causing the spring to pull or compress the rope, changing the resistance during gear rotation and thus altering the training intensity.

[0014] Secondly, it can easily adjust the height of the volleyball according to the height of different athletes, making it convenient for athletes to practice passing. By pushing the fixed frame to slide relative to the fixed sleeve rod, the spring is compressed, and the fixed opening is moved out from the second fixed opening and the first fixed opening. Then, the fixed rod is pulled to slide relative to the fixed sleeve rod to adjust the height of the volleyball. The fixed frame is reset under the action of the spring, and the fixed block is driven to lock into the corresponding second fixed opening.

[0015] Thirdly, it allows athletes to practice passing the volleyball when it falls from different directions. When the volleyball falls, it causes the rope to vibrate, which causes the limiter to slide freely on the limiter rod. Moreover, the limiter rod will rotate relative to the connecting rod, thereby causing the volleyball to change its position and allowing for better training. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0025] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Example, refer to Figure 1-5 A volleyball training device for passing the ball includes a preparation. A support 1 has an inner shell 2. The upper front side of the shell 2 has a rope-threading opening 3. A horizontally arranged rotating shaft 4 is rotatably connected between the middle of the left and right ends inside the shell 2. A gear 5 is rotatably connected to the left and right ends of the outer side of the rotating shaft 4. Each gear 5 has a spring 6 that is always in a compressed state inside, which can ensure that the rotating shaft 4 can rotate relative to the gear 5. One end of each spring 6 is connected to the rotating shaft 4, and the other end of each spring 6 is connected to the corresponding gear 5, which can provide resistance to the arm when passing the ball, thereby training the arm strength.

[0027] A worm gear 13 is provided in the middle of the outer side of the rotating shaft 4. A worm 14 is rotatably connected to the front and rear ends of the housing 2 near the worm gear 13 and is arranged horizontally. This allows for easy adjustment of the resistance when padding the ball, thereby changing the training intensity. A knob 15 is provided at the front end of the worm 14 through the housing 2. A limiting shaft 7 is vertically provided on the front side of the lower end of the housing 2 near each gear 5.

[0028] The inner casing 2 has a horizontally slidable pull rod 8 that is slidably connected to each limiting shaft 7. On the left and right sides of the lower end of the pull rod 8, there is a rack 9 that is slidably connected to the corresponding pull rod 8 and meshes with the corresponding gear 5. A roller 12 is rotatably connected to the middle of the front side of the upper end of the bracket 1, which can facilitate the movement of the pull rope 10. A pull rope 10 is provided in the middle of the upper end of the pull rod 8, which passes through the rope insertion port 3 and is rotatably connected to the roller 12. Two elastic fixing sleeves are provided at equal intervals at the end of the pull rope 10 that passes through the rope insertion port 3, which can facilitate training for athletes with different arm sizes.

[0029] A lifting device is provided at the middle of the rear end of the support 1, including a fixed sleeve rod 16 vertically arranged at the middle of the rear end of the support 1. A first fixing port 17 is opened on the upper side of the front end of the fixed sleeve rod 16. A vertically arranged fixing rod 21 is slidably connected inside the fixed sleeve rod 16. Several second fixing ports 22 are opened at equal intervals at the front end of the fixing rod 21. A fixing frame 18 is slidably connected to the upper end of the outer side of the fixed sleeve rod 16. A fixing block 20 is provided at the front end of the inner side of the fixing frame 18, which is slidably connected to the first fixing port 17 and to each of the second fixing ports 22. Multiple springs 19 are arranged at equal intervals between the rear end of the inner side of the fixing frame 18 and the fixed sleeve rod 16, which can be adjusted for easy height adjustment, so as to facilitate training for athletes of different heights.

[0030] A connecting rod 23 is horizontally installed at the upper end of the fixed rod 21. A limiting slide rod 24 is rotatably connected to the front side of the lower end of the connecting rod 23. A sliding sleeve 25 is rotatably connected to the outer side of the limiting slide rod 24. A connecting rope 26 is installed on the outer side of the sliding sleeve 25. A volleyball 27 is installed at the lower end of the connecting rope 26, which can drop the volleyball 27 from different directions to allow athletes to train better.

[0031] Usage: When using the volleyball, the athlete secures the elastic retaining sleeve 11 to their wrist. By pressing the retaining frame 18 and sliding it relative to the retaining sleeve rod 16, the spring 19 is compressed, causing the limiting block to move out of the second retaining port 22 and the first retaining port 17. Then, the athlete pulls the retaining rod 21 relative to the retaining sleeve rod 16, allowing the retaining block 20 to connect with different second retaining ports 22, thereby causing the connecting rod 23 to move up and down, adjusting the height of the volleyball 27 to facilitate training for people of different heights. The athlete then clasps their hands together, raises the volleyball 27, and trains. During training, the elastic retaining sleeve 11 pulls the pull rope 10 out of the rope threading port 3, causing the pull rope 10 to move... Roller 12 rotates, and at the same time, the pull rope 10 drives the pull rod 8 to slide relative to the limit shaft 7, which in turn drives the rack 9 to slide relative to the limit shaft 7. The rack 9 drives the gear 5 to rotate. Due to the action of the worm gear 13 and worm 14, when the gear 5 rotates, it will not drive the shaft 4 to rotate. The rotation of the gear 5 drives the spring 6 to compress and generate elastic force, providing resistance during training, thereby training the athlete's arm strength. After the volleyball 27 is raised and dropped, the volleyball 27 will drive the sliding sleeve 25 to slide relative to the limit sliding rod 24 through the pull rope 10, and at the same time, it will drive the limit sliding rod 24 to rotate relative to the connecting rod 23, which makes it convenient for the athlete to pass the volleyball 27 that falls from different directions.

[0032] By turning knob 15, the worm gear 14 is driven to rotate, which in turn drives the worm wheel 13 to rotate. The worm wheel 13 drives the shaft 4 to rotate, which in turn drives the spring 6 to compress or stretch. This changes the resistance to the rotation of the gear 5 when the rack 9 moves upward, thereby changing the training intensity of the athlete's arm strength. Since the spring 6 is initially in a compressed state, it can always generate elasticity, which in turn drives the rack 9 to always move downward. The worm gear 14 can drive the shaft 4 to rotate relative to the gear 5.

[0033] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
