Description

Technical Field

[0001] This utility model relates to the field of sports teaching equipment technology, specifically to a movement demonstration device for sports teaching. Background Technology

[0002] In physical education, movement demonstration is a teaching method in which teachers or demonstrators present the complete process, breakdown steps, and key points of a motor skill to students through intuitive and standardized physical displays. During demonstrations, teachers combine verbal explanations, clearly demonstrating the details of each step from the starting posture and movement trajectory to the finishing posture. They also use methods such as slow breakdowns and comparisons of correct and incorrect movements to help students establish correct movement representations, understand the principles of movement, and thus effectively imitate and practice to master the motor skill. Appropriate demonstration equipment is needed to assist in teaching movement demonstrations.

[0003] In traditional physical education demonstrations, display equipment is typically fixed in place, resulting in a limited viewing angle and coverage. To allow students to see the details of the movements from different angles, teachers often need to repeatedly adjust their own position or the equipment's placement, which is time-consuming and reduces teaching efficiency. While some mobile devices can be repositioned, the process of fixing and adjusting them is cumbersome, making it difficult to achieve quick and flexible multi-angle displays. This limits students' comprehensive observation and understanding of the movements and hinders the implementation of effective physical education activities. Utility Model Content

[0004] The purpose of this invention is to provide a movement demonstration device for physical education teaching, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a physical education teaching action demonstration device, including a base, a rotating mechanism fixedly connected to the top of the base, and an adjustment mechanism fixedly connected to the top of the rotating mechanism;

[0006] The rotating mechanism includes a support column, which is fixedly connected to the top of the base. An I-shaped circular seat is rotatably connected to the upper surface of the support column, and a positioning plate is fixedly connected to the lower surface of the I-shaped circular seat. Springs are fixedly connected to the top of the left and right sides of the support column, and an I-shaped rod is fixedly connected to one end of each spring. A pull plate is fixedly connected to the surface of the I-shaped rod, and a locking rod is fixedly connected inside the pull plate.

[0007] Preferably, a circular hole is formed inside the support column, and the surface of the I-shaped rod is rotatably connected to the inside of the circular hole, so as to facilitate the movement of the I-shaped rod within the circular hole.

[0013] Compared with the prior art, this utility model provides a movement demonstration device for physical education teaching, which has the following beneficial effects:

[0014] 1. This physical education teaching action demonstration equipment, through a set rotating mechanism, allows the pull plate to rotate downwards using the I-shaped rod supported by the support column. This causes the locking rod to move downwards and disengage from the locking position inside the positioning plate. Then, the pull plate can be rotated to drive the I-shaped circular seat to rotate under the support of the support column, thereby driving the demonstration display equipment to rotate and expanding the display range of the teaching action demonstration. This facilitates students' comprehensive observation and understanding of the actions and is conducive to the development of efficient physical education teaching activities.

[0015] 2. This physical education teaching action demonstration equipment, through its set adjustment mechanism, rotates a knob to drive a worm gear, which in turn drives a support rod to rotate under the support of the ear seat. This, in turn, drives the demonstration display equipment to rotate, and allows for adjustment of the display angle of the teaching action demonstration. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between 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.

[0024] This utility model provides the following technical solution:

[0025] Example 1

[0026] Combination Figures 2 to 4 A physical education teaching action demonstration device includes a base 1, a rotating mechanism 2 fixedly connected to the top of the base 1, and an adjusting mechanism 3 fixedly connected to the top of the rotating mechanism 2.

[0027] The rotating mechanism 2 includes a support column 21, which is fixedly connected to the top of the base 1. An I-shaped circular seat 22 is rotatably connected to the upper surface of the support column 21, and a positioning plate 23 is fixedly connected to the lower surface of the I-shaped circular seat 22. Springs 24 are fixedly connected to the top of the left and right sides of the support column 21, and an I-shaped rod 25 is fixedly connected to one end of the spring 24. A pull plate 26 is fixedly connected to the surface of the I-shaped rod 25, and a locking rod 27 is fixedly connected inside the pull plate 26. A circular hole is opened inside the support column 21, and the surface of the I-shaped rod 25 is rotatably connected to the circular hole. A positioning hole is opened inside the positioning plate 23, and the surface of the locking rod 27 matches the positioning hole.

[0028] Furthermore, support holes are respectively opened at both ends of the surface of the pull plate 26, and the surface of the locking rod 27 is fixedly connected to the support holes. By moving the pull plate 26, the I-shaped rod 25 is rotated downward under the support of the support column 21, thereby driving the locking rod 27 downward to disengage it from the locking position inside the positioning plate 23. Then, the pull plate 26 can be rotated to drive the I-shaped round seat 22 to rotate under the support of the support column 21, thereby driving the demonstration display device 32 to rotate and expanding the display range of the teaching action demonstration of the demonstration display device 32.

[0029] Example 2

[0030] See Figure 1-4 Furthermore, based on Embodiment 1, the adjustment mechanism 3 includes an ear seat 31, which is fixedly connected to the top of the I-shaped round seat 22. A support rod 33 is rotatably connected inside the ear seat 31. A demonstration display device 32 is fixedly connected to the surface of the support rod 33. A worm gear 34 is fixedly connected to the right end of the support rod 33. A gate-shaped strip 36 is fixedly connected to the right side of the support column 21. A knob 35 is fixedly connected to the top of the worm gear 34. A rotating hole is opened on the surface of the gate-shaped strip 36, and the surface of the worm gear 34 is rotatably connected to the rotating hole.

[0031] Furthermore, a perforation is made inside the ear base 31, and the surface of the support rod 33 is rotatably connected to the perforation. When the knob 35 is turned, the worm gear 34 is rotated, thereby causing the support rod 33 to rotate under the support of the ear base 31. This, in turn, causes the demonstration display device 32 to rotate, and the display angle of the teaching action demonstration can be adjusted.

[0032] In actual operation, when this device is used, the surface size of the locking rod 27 is smaller than the internal size of the positioning plate 23. When demonstrating sports teaching actions, the operator can use the demonstration display device 32 to make corresponding demonstrations. When it is necessary to adjust the demonstration angle, the pull plate 26 is turned downwards by the I-shaped rod 25 under the support of the support column 21, thereby driving the locking rod 27 downwards to disengage it from the locking position inside the positioning plate 23. Then, the pull plate 26 can be rotated to drive the I-shaped round seat 22 to rotate under the support of the support column 21, thereby driving the demonstration display device 32 to rotate and expanding the display range of the teaching action demonstration of the demonstration display device 32.

[0033] In addition, when it is necessary to adjust the display angle, turning the knob 35 drives the worm gear 34 to rotate, thereby driving the support rod 33 to rotate under the support of the ear seat 31, which in turn drives the demonstration display device 32 to rotate, and can adjust the display angle of the teaching action demonstration.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
