Technical Field
[0001] This utility model relates to the field of sports technology, and more specifically, to a sports education exercise device. Background Technology
[0002] In physical education, to improve students' abilities, continuous practice and training are necessary. For example, hurdling is a training method where students can improve their abilities through continuous practice. Currently, the training method for hurdling involves placing a row of hurdles on the playground for students to practice and train continuously.
[0003] During student training, students often trip over the hurdles because they cannot adapt to the height at first. Although a single fall of the hurdle will not affect its performance, repeated training over a long period of time is required. Frequent falls of the hurdle during use can lead to its breakage and affect its usability. Therefore, a physical education training device is proposed to solve the above problems. Utility Model Content

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] Example
[0029] Reference Figures 1-4 This utility model provides a technical solution: a physical education exercise device, including a support frame 1 and a protective mechanism 3, with a connecting rod 2 installed on the inner side of the support frame 1. The protective mechanism 3 includes a connecting rod 31, which is rotatably installed on the outer surface of the support frame 1. A positioning plate 32 is stably installed on the outer surface of the support frame 1, and a support rod 321 is rotatably installed on the positioning plate 32. A support block 33 is stably installed at the bottom of the support rod 321, and the connecting rod 31 is rotatably connected to the support rod 321.
[0030] In a preferred embodiment, one end of the connecting rod 2 is fixedly mounted with a sliding block 4, which is slidably connected to the inner side of the support frame 1. This device has a sliding block 4 installed at one end of the connecting rod 2 and is slidably mounted to the inner side of the support frame 1, which allows the position of the connecting rod 2 to be adjusted to meet the needs of actual exercise and facilitates use.
[0031] In a preferred embodiment, the outer surface of the support frame 1 is provided with screw holes 5, and one side of the sliding block 4 is provided with through holes 6. Several screw holes 5 are provided and evenly distributed on the outer surface of the support frame 1. The screw holes 5 are threadedly connected to screw rods 7, and one end of screw rods 7 extends into the through holes 6. After adjusting the position of the connecting rod 2, it is necessary to ensure that the connecting rod 2 can be used stably. Therefore, screw holes 5 are provided on the outer surface of the support frame 1, and through holes 6 are provided on one side of the sliding block 4. By screwing screw rods 7 into the screw holes 5 and extending one end of screw rods 7 into the through holes 6, the connecting rod 2 can be positioned so as to ensure the stable use of the connecting rod 2.
[0032] In a preferred embodiment, a placement seat 8 is fixedly installed at the bottom of the support frame 1, and an anti-slip pad 9 is provided at the bottom of the placement seat 8. When this device is in use, it is mostly placed on the ground. In order to prevent the device from sliding at will, an anti-slip pad 9 is glued to the bottom of the placement seat 8. The friction between the anti-slip pad 9 and the bottom surface is increased, which can make the device stable to use.
[0033] In physical education teaching, a large number of hurdles need to be moved to the playground. To facilitate the movement of the hurdles, a moving mechanism 10 is also set on the support frame 1. The moving mechanism 10 includes a roller 101, a spring 102, and a limiting rod 103. The support frame 1 has a circular hole 11 inside, which passes through the interior of the placement seat 8. The spring 102 is fixedly installed at the top of the circular hole 11. One end of the spring 102 is stably connected to the circular rod 12. The bottom end of the circular rod 12 is equipped with a roller 101 for controlling the movement of the support frame 1. The limiting rod 103 is rotatably installed on the outer side of the circular rod 12. A support rod 13 is installed on the outside of the circular rod 12. The support rod 13 is fixedly connected to the limiting rod 103, and a torsion spring is installed on the support rod 13. A limiting block 14 is fixedly installed on the outer surface of the circular rod 12 for limiting the limiting rod 103.
[0034] In actual use, when moving this device to the playground, the roller 101 can be pulled to pull one end of the round rod 12 out of the support frame 1, and the roller 101 can be pulled out of the support frame 1. At the same time, the limiting rod 103 also needs to be pulled out of the support frame 1. Since the limiting rod 103 is connected to the support rod 13 and a torsion spring is provided on the support rod 13, when the limiting rod 103 is pulled out from the round hole 11, the limiting rod 103 will unfold under the action of the torsion spring, and the outer surface of the limiting rod 103 will fit against the bottom of the placement seat 8. The support frame 1 can then be placed vertically, and the roller 101 can be placed on the ground. The support frame 1 can then be moved directly to move this device to the playground for use.
[0035] Specifically, the working process or working principle of a physical education exercise device is as follows: During the exercise process for students, since students cannot adapt to the height of the hurdles at the beginning, they will always trip over the hurdles when learning to hurdle. Although a single hurdle tipping over will not affect the hurdle, in daily training, multiple long-term exercises are required. The frequent tipping of the hurdle during use will lead to the hurdle breaking. Therefore, this device was designed to solve this problem.
[0036] This device can protect against hurdles. When a hurdle tilts, it will cause the support rod 321 to rotate, making the support rod 321 perpendicular to the ground. This allows the support block 33 to be placed on the ground, protecting the support frame 1. Specifically, the device is placed on the playground and spaced apart. When students exercise, the connecting rod 2 is easily moved by the students, causing the support frame 1 to tilt. When the support frame 1 tilts, the support rod 321 will rotate. As the tilt angle of the support frame 1 increases, the support rod 321 will become perpendicular to the ground, and the support block 33 will be placed on the ground, preventing the support frame 1 from hitting the ground and avoiding damage to the support frame 1.
[0037] To improve the effectiveness of this device, when the support rod 321 rotates, it will also drive the connecting rod 31 to rotate. When the support rod 321 touches the ground, the connecting rod 31 will support the support rod 321, thereby limiting the support rod 321 and making it stably touch the ground, thus protecting the support frame 1 and meeting the usage requirements.
[0038] When using this device, the position of connecting rod 2 can be adjusted to meet the exercise needs of students. By turning screw 7, connecting rod 2 can be moved. Control the movement of sliding block 4, which in turn moves connecting rod 2, thereby adjusting the position of connecting rod 2 inside the support frame 1. Once the position of connecting rod 2 is determined, screw 7 into the screw hole 5 and into the through hole 6 to position sliding block 4, thus enabling stable use of connecting rod 2.
[0039] When moving this device to the playground, the roller 101 can be pulled to pull one end of the round rod 12 out of the support frame 1, and the roller 101 can be pulled out of the support frame 1. At the same time, the limiting rod 103 also needs to be pulled out of the support frame 1. Since the limiting rod 103 is connected to the support rod 13 and a torsion spring is provided on the support rod 13, when the limiting rod 103 is pulled out from the round hole 11, the limiting rod 103 will unfold under the action of the torsion spring and make the outer surface of the limiting rod 103 fit against the bottom of the placement seat 8. The support frame 1 can then be placed vertically, and the roller 101 can be placed on the ground. The support frame 1 can then be moved directly, making it convenient to move this device to the playground.
[0040] When the device is in normal use, the round rod 12 can be pulled again. When the limiting rod 103 separates from the bottom of the placement seat 8, the limiting rod 103 will rotate under the action of the torsion spring and come close to the outer surface of the round rod 12. Then the round rod 12 is released, and the round rod 12 will drive the roller 101 to move into the interior of the support frame 1 under the retraction of the spring 102. At this time, the placement seat 8 can be placed on the ground. The placement seat 8 can support the support frame 1, thereby controlling the stable use of the device.
