Description

Technical Field

[0001] This utility model relates to the field of sports training equipment technology, specifically a medicine ball throwing training and testing device. Background Technology

[0002] Sports training equipment is a general term for tools, instruments, or systems designed to improve athletic ability, optimize technical movements, enhance physical fitness, or assist in rehabilitation training. Its core function is to help athletes or fitness enthusiasts achieve their training goals more efficiently and safely through scientific and structured methods.

[0003] An existing patent (publication number: CN217067609U) discloses a solid ball throwing training and testing device, comprising two symmetrically fixed bases at both ends of a throwing point. Both bases have an L-shaped cross-section, and the free ends of the horizontal portions of both bases are equipped with transmission racks. A movable frame with an inverted "U"-shaped cross-section is commonly mounted on both bases. Two mounting plates are fixedly mounted at the lower ends of the movable frame, and each mounting plate is equipped with a drive motor. The drive shaft of each drive motor passes through the mounting plate and has a transmission gear at its end that matches the corresponding transmission rack. An infrared rangefinder and two symmetrical lifting push rods are mounted on the upper part of the movable frame. The telescopic ends of the two lifting push rods pass through the top plate of the movable frame and are jointly and fixedly connected to a ball-collecting device. This invention reduces the physical exertion of personnel and improves training and testing efficiency.

[0004] The aforementioned medicine ball throwing training and testing device can automatically retrieve the ball during use, reducing the physical exertion of staff. However, it lacks protection for users. When middle school students throw medicine balls, their body coordination and strength control are still developing, and their movements are not standardized enough. During the back-lifting motion while throwing the medicine ball, they are prone to muscle strains, leading to frequent sports injuries, which affect the normal training progress and the physical health of middle school students. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a solid ball throwing training and testing device, which has advantages such as improved protection during shot put training and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a solid ball throwing training and testing device, including a protective pad, an auxiliary mechanism, and a recovery component. The surface of the protective pad is marked with landing area scale markings, and the upper end of one side of the protective pad along its length is inclined. The auxiliary mechanism includes protective components and adjustment components; Among them, the protective components are used to protect the waist of middle school students; The adjustment component is used to adjust the height of the protective component; The recovery unit is used to retrieve the shot put after it has been thrown.

[0007] Furthermore, the protective assembly includes a rotating block, with two buffer cylinders fixedly connected to one side of the rotating block. Each buffer cylinder has a buffer rod slidably connected inside, and each buffer rod is fixedly connected to an adjacent buffer cylinder with a spring. Each buffer cylinder has an air inlet on its circumferential surface, and a bearing plate is hinged to the other end of the lower buffer rod.

[0008] The above-described design, which combines a buffer cylinder and a buffer rod, provides lumbar support for middle school students, preventing strains caused by excessive force during back lifting. In early training, the air inlet is sealed with a plug. When the buffer rod is under stress, the spring is compressed, providing assistance to the student's lower back during shot put throws. This provides additional thrust as the spring pushes the support plate during the throw, suitable for early training. In later training, the air inlet is connected to the outside environment. When the spring pushes the slide bar back to its original position, air takes time to enter the buffer cylinder from the air inlet. Therefore, when the student's back separates from the support plate, the spring slowly returns to its original state, no longer providing thrust to the student's lower back, suitable for later training.

[0009] Furthermore, the adjustment assembly includes a support frame, a lead screw is rotatably connected to the inner wall of the support frame, a drive motor is fixedly installed at the upper end of the support frame, the output shaft of the drive motor is fixedly connected to the upper end of the lead screw, a slide rail is provided on one side of the support frame corresponding to the lead screw, and an adjustment component is slidably connected along the vertical direction of the slide rail, the adjustment component is threadedly connected to the lead screw, and a rotating block is located inside the adjustment component and rotatably connected to the adjustment component.

[0010] The above solution uses a drive motor to rotate the lead screw, which in turn drives the adjusting component to slide along the slide rail of the support frame. This allows the height of the bearing plate to be adjusted via the buffer cylinder and buffer rod, making it convenient for middle school students of different heights to use.

[0011] Furthermore, the adjustment assembly also includes two torsion springs fixedly connected between the lower buffer rod and the support plate. The end of the upper buffer rod near the support plate is arc-shaped and contacts the support plate. Polygonal grooves are opened on the side of the adjustment component adjacent to the rotating block, and a polygonal column is inserted between the two polygonal grooves.

[0012] The above design, which hinges the support plate and the lower buffer rod to the upper buffer rod, allows the upper end of the support plate to rotate and conform to the student's back when the student's waist comes into contact with it. This adapts to the student's back curve, providing more comfortable and supportive support and effectively dispersing the pressure on the lower back.

[0013] Furthermore, the recycling assembly includes multiple bases, each base having a protective net installed on its upper end. Slide grooves are provided on the corresponding sides of the bases located on both sides of the protective pad. Recycling racks are slidably connected inside the two slide grooves. Rollers are installed at the bottom of adjacent sides of the two recycling racks, and both rollers are in contact with the protective pad. Lead screws are rotatably connected to the inner walls of the two slide grooves. The two recycling racks are threadedly connected to their respective lead screws, and one end of each lead screw is fixedly connected to the output shaft of an external motor.

[0014] With the above scheme, the recovery rack is set up so that when the external motor drives the second lead screw to rotate, the second lead screw drives the recovery rack to slide in the sliding groove, and pushes the lead ball on the protective pad to roll, so that the lead ball rolls to the inclined end of the protective pad and rolls along the inclined end of the protective pad to the throwing area.

[0015] Furthermore, the recycling assembly also includes a U-shaped frame mounted on the surface of the protective pad.

[0016] The above scheme allows the U-shaped frame to intercept the shot put, preventing it from rolling to the students' feet and affecting shot put throwing training. Furthermore, the U-shaped frame ensures that the retrieved shot put is positioned in front of the throwing area, facilitating subsequent shot put throwing training.

[0017] Furthermore, a baffle is fixedly connected to the side of the base corresponding to the auxiliary mechanism, and both recycling racks are located below the baffle.

[0018] The above solution, by setting up baffles, can prevent shot put from falling onto the recycling rack and thus prevent shot put from hitting the recycling rack and affecting its use.

[0019] Furthermore, two counterweight lead plates are provided on the upper surface of the support frame.

[0020] By using the above method, setting a counterweight lead plate can increase the weight at the bottom of the support frame, keep the support frame stable, and prevent the support frame from tipping over when the student pushes the load plate with their waist.

[0021] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: This solid ball throwing training and testing device, by setting up a protective component, can conform to the waist contour of middle school students when they are training in the back-raising posture, providing them with stable and appropriate auxiliary support, effectively dispersing the huge pressure on the waist during the back-raising process, avoiding waist muscle strain due to overstretching or uneven force, and ensuring the physical safety of middle school students during training. The adjustment component has a flexible height adjustment function. Since middle school students are in a rapid development stage, there are large differences in height and body proportion. The adjustment component can adjust the height of the protective component according to the actual height of different middle school students. Whether the student is relatively short or tall, the protective component can be adjusted to the most suitable height for them, ensuring that the protective component can always play the best protective and support role, greatly enhancing the versatility and practicality of the device. The recovery component is designed to collect shot puts scattered around the area after students finish throwing the shot put. The shot puts will roll smoothly along the slope of the protective mat and eventually automatically gather in the designated area, eliminating the need to frequently bend over to pick up the shot puts, greatly reducing the workload of picking them up and saving training time.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figures 1-6 This embodiment of a shot put training and testing device includes a protective pad 1, an auxiliary mechanism 2, and a recovery component 3. The surface of the protective pad 1 is marked with landing area scale markings 4, which facilitates intuitive recording and evaluation of the throwing distance and provides a quantitative reference for training effectiveness. The protective pad 1 is made of rubber, which can cushion the shot put and prevent the ground from being damaged by the impact of the shot put. The upper end of one side of the protective pad 1 along its length is inclined, which guides the shot put to roll naturally and roll through the slope of the protective pad 1 to the throwing area, making it easy to recover the shot put after it is thrown.

[0026] The auxiliary mechanism 2 includes a protective component 201 and an adjustment component 202.

[0027] Among them, the protective component 201 is used to protect the middle school student's waist and prevent waist strain during the back-raising process. The protective component 201 can provide auxiliary support for the middle school student's waist during the back-raising posture and prevent waist muscle strain during the back-raising movement.

[0028] The adjustment component 202 is used to adjust the height of the protective component 201, making it convenient for middle school students of different heights to use. The adjustment component 202 can adjust the height of the protective component 201. Since middle school students are in the developmental stage and their height ratios vary greatly, the adjustment component 202 can adjust the height of the protective component 201 to suit middle school students of different heights.

[0029] The recovery component 3 is used to recover the shot put after it has been thrown. The recovery component 3 can recover the shot put after it has been thrown and make the shot put roll along the slope of the protective pad 1 back to the throwing area, reducing the workload of picking up the shot put and improving training efficiency.

[0030] The protective component 201 includes a rotating block 2011. Two buffer cylinders 2012 are fixedly connected to one side of the rotating block 2011. A buffer rod 2013 is slidably connected inside each buffer cylinder 2012. A spring 2014 is fixedly connected between each buffer rod 2013 and the adjacent buffer cylinder 2012. An air inlet 2015 is provided on the circumferential surface of each buffer cylinder 2012. A bearing plate 2016 is hinged to the other end of the lower buffer rod 2013. A protruding structure is provided on the outer circumferential surface of the lower buffer rod 2013, which contacts and limits its movement with the bottom end of the bearing plate 2016 to prevent the upper end of 2013 from rotating in the opposite direction. The cooperation between the buffer cylinders 2012 and the buffer rods 2013 can support the waist of middle school students and prevent excessive force during back lifting. To prevent strains, during early training, the air inlet 2015 is blocked with a plug. When the buffer rod 2013 is under force, the spring 2014 is compressed. When the student throws the shot put, the spring 2014 provides assistance to the student's waist, providing auxiliary thrust when the spring 2014 pushes the support plate 2016 during the throw. This is used for early training. In later training, the air inlet 2015 is connected to the outside. When the spring 2014 pushes the slide rod back to its original position, it takes time for air to enter the buffer cylinder 2012 from the air inlet 2015. Therefore, when the student's back separates from the support plate 2016, the spring 2014 slowly returns to its original state and does not provide thrust to the student's waist. This is used for later training.

[0031] The adjusting assembly 202 includes a support frame 2021. A lead screw 2022 is rotatably connected to the inner wall of the support frame 2021. A drive motor 2023 is fixedly mounted on the upper end of the support frame 2021. The output shaft of the drive motor 2023 is fixedly connected to the upper end of the lead screw 2022. A slide rail 2024 is provided on one side of the support frame 2021 corresponding to the lead screw 2022. An adjusting component 2025 is slidably connected along the vertical direction of the slide rail 2024. The adjusting component 2025 is threadedly connected to the lead screw 2022. A rotating block 2011 is located inside the adjusting component 2025 and is rotatably connected to the adjusting component 2025. The drive motor 2023 drives the lead screw 2022 to rotate, so that the lead screw 2022 can drive the adjusting component 2025 to slide along the slide rail 2024 of the support frame 2021 during the rotation. This allows the height of the bearing plate 2016 to be adjusted through the buffer cylinder 2012 and the buffer rod 2013, making it convenient for middle school students of different heights to use. The upper surface of the support frame 2021 is provided with two counterweight lead plates 7. The counterweight lead plates 7 can increase the weight at the bottom of the support frame 2021, keep the support frame 2021 stable, and prevent the support frame 2021 from tipping over when the student pushes the bearing plate 2016 with force.

[0032] The adjustment assembly 202 also includes two torsion springs 2026 that are fixedly connected between the lower buffer rod 2013 and the support plate 2016. The upper buffer rod 2013 is arc-shaped at one end near the support plate 2016 and contacts the support plate 2016. The adjustment component 2025 and the rotating block 2011 are both provided with polygonal grooves 2027 on the side adjacent to each other. Polygonal posts 2028 are inserted between the two polygonal grooves 2027. Through the design of the support plate 2016 and the lower buffer rod 2013 being hinged to the upper buffer rod 2013, when the middle school student's waist contacts the support plate 2016, the upper end of the support plate 2016 can rotate and fit against the student's waist and back, thereby adapting to the student's waist and back curve, providing the student with more comfortable and fitting support, and effectively dispersing the pressure on the waist.

[0033] The recycling assembly 3 includes multiple bases 301, each base 301 having a protective net 302 installed on its upper end. Each base 301 located on either side of the protective pad 1 has a corresponding groove 303. A recycling rack 304 is slidably connected inside each groove 303. Rollers 305 are installed at the bottom of adjacent sides of each recycling rack 304, and both rollers 305 contact the protective pad 1. Lead screws 306 are rotatably connected to the inner walls of each groove 303. Each recycling rack 304 is threadedly connected to its corresponding lead screw 306, and one end of each lead screw 306 is fixed to the output shaft of an external motor. The connection allows the recovery rack 304 to slide within the groove 303 when the external motor drives the lead screw 306 to rotate, thus pushing the shot put on the protective pad 1 to roll. The shot put rolls to the inclined end of the protective pad 1 and then rolls along the inclined end of the protective pad 1 to the throwing area. The recovery assembly 3 also includes a U-shaped frame 5 installed on the surface of the protective pad 1. The U-shaped frame 5 can intercept the shot put, preventing it from rolling to the students' feet and affecting shot put throwing training. Furthermore, the shape of the U-shaped frame 5 ensures that the recovered shot put is located in front of the throwing area, facilitating subsequent shot put throwing training.

[0034] A baffle 6 is fixedly connected to the side of the base 301 corresponding to the auxiliary mechanism 2. Both recycling racks 304 are located below the baffle 6. The baffle 6 can prevent the lead ball from falling onto the recycling rack 304 and prevent the lead ball from hitting the recycling rack 304 and affecting the use of the recycling rack 304.

[0035] The working principle of the above embodiment is as follows: First, when the height of the support plate 2016 is adjusted by the adjustment component 202, the drive motor 2023 drives the lead screw 2022 to rotate, so that the lead screw 2022 can drive the adjustment component 2025 to slide along the slide rail 2024 during the rotation, so that the adjustment component 2025 is at a suitable height.

[0036] After the height of the support plate 2016 is adjusted, the polygonal column 2028 in the polygonal groove 2027 is pulled out and the rotating block 2011 is rotated to adjust the support plate 2016 to a suitable angle. Then, it is reinserted into the polygonal groove 2027 to position the rotating block 2011.

[0037] When middle school students practice throwing, they lift their backs. During this movement, the student's back contacts the support plate 2016. The upper part of the support plate 2016 rotates under pressure, conforming to the student's back and preventing excessive back strain. Finally, the two buffer rods 2013 slide within the buffer cylinder 2012, compressing the spring 2014. Simultaneously, air inside the buffer cylinder 2012 is expelled through the air inlet 2015. When the student throws, it takes time for air to enter through the air inlet 2015, therefore the spring 2014... 14 will slowly return to its original position. The support plate 2016 will not provide auxiliary physical strength to the student, which is helpful for throwing practice. When beginners practice, the plug is inserted into the air inlet 2015 to block the buffer cylinder 2012, so that the buffer cylinder 2012 is in a closed state. The spring 2014 will also be compressed. When the student throws, the deformation force of the spring 2014 will push the support plate 2016 to provide assistance to the student's back, thereby improving the assistance effect of throwing training. In this way, it can not only protect the student's waist, but also provide assistance to beginners.

[0038] After the shot put is thrown, the protective net 302 can protect the landing area of ​​the shot put and prevent it from hitting the ground. After the shot put comes into contact with the protective pad 1, the impact force of the shot put will also be absorbed by the protective pad 1, so that the shot put remains stable and prevents the shot put from rolling. Students can judge the distance of the shot put by the landing area scale markings 4 on the protective pad 1.

[0039] When it is necessary to retrieve the shot put after it has been thrown, an external motor drives two lead screws 306 to rotate. The two lead screws 306 can drive two retrieval frames 304 to move closer to the throwing area and push the shot put after it has been thrown to the inclined part of the protective pad 1. After the shot put rolls and comes into contact with the U-shaped frame 5, it rolls to the front of the throwing area, making it easy to pick up and throw for training.
