Description

Technical Field

[0001] This utility model relates to the field of sports teaching equipment technology, and in particular to an adjustable high jump training device for sports teaching. Background Technology

[0002] Physical education is a purposeful and organized educational process carried out according to a certain plan and curriculum standards. It involves both teachers and students and its task is to impart sports knowledge, techniques and skills to students, enhance their physical fitness, and cultivate their morality, will, and character. There are many different sports teaching programs, and high jump training is one of them.

[0003] Common adjustable high jump training devices used in physical education have a relatively simple structure, usually consisting of a horizontal bar erected at different heights on two vertical poles. This type of training device has certain drawbacks. In actual use, if a student touches the horizontal bar and causes it to fall off, it needs to be re-erected, especially at higher positions, where it is very inconvenient to set up and lacks practicality. Therefore, we propose an adjustable high jump training device for physical education. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies. Common adjustable high jump training devices used in physical education have a relatively simple structure, usually consisting of a horizontal bar erected at different heights on two vertical poles. This type of training device has certain drawbacks. In actual use, if a student touches the horizontal bar and causes it to fall off, it needs to be re-erected, especially at higher positions, where it is very inconvenient to set up and lacks practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable high jump training device for physical education includes a base, and adjustment mechanisms are symmetrically installed on the top of the base near the left and right sides.

[0007] The base is equipped with a drive assembly.

[0008] The adjustment mechanism includes a fixed column welded to the top of the base. An adjustment component is installed inside the fixed column. A crossbar component is installed inside the adjustment component and located inside the fixed column. A reset component is installed on the periphery of the fixed column.

[0009] As a preferred embodiment of this utility model, the driving component includes a linkage rod, which is rotatably connected to the base. A first gear is welded to the outer periphery of the linkage rod near the left side. A second gear is meshed with the top of the first gear. A handle is welded to the top of the second gear. The handle is rotatably connected to the base. A third gear is welded to the outer periphery of the linkage rod corresponding to the adjustment mechanism.

[0010] The technical effect of adopting the above-mentioned further solution is that the second gear can be driven to rotate by turning the handle, thereby driving the connecting rod and the third gear to rotate through the first gear, providing power to the adjustment component.

[0011] As a preferred embodiment of this utility model, the adjusting component includes a lead screw, which is rotatably connected to a fixed column. A fourth gear is fixedly connected to the bottom of the lead screw extending into the interior of the base. The fourth gear meshes with a third gear. A slider is sleeved around the lead screw, and a rotating shaft is fixedly connected to the inner side of the slider.

[0012] The technical effect of adopting the above-mentioned further solution is that the fourth gear can drive the lead screw to rotate with the third gear, thereby allowing the lead screw to drive the crossbar assembly to adjust its height through the slider and the rotating shaft.

[0013] As a preferred embodiment of this utility model, a stop block is welded to the front of the rotating shaft.

[0014] The technical effect of adopting the above-mentioned further solution is that the stop block can limit the stop bar to prevent it from rotating in the front, thereby improving the ease of use.

[0015] As a preferred embodiment of this utility model, a limiting groove is provided on the inner side of the fixing column and on the outer periphery of the slider.

[0016] The technical effect of adopting the above-mentioned further solution is that the limiting groove can limit the movement of the slider, prevent it from rotating helically with the lead screw, and improve the stability of use.

[0017] As a preferred embodiment of this utility model, the crossbar assembly includes a stop bar, the outer end of which is rotatably connected to a rotating shaft, and the inner end of which is slidably connected to a locking member, with a magnet fixedly installed on the inner side of the locking member.

[0018] The technical effect of adopting the above-mentioned further solution is that the magnet can be easily fixed by the clip. When the inner ends of the two stops are close, the two magnets attract each other and can drive the clip to slide inward, thus completing the connection of the two crossbar assemblies.

[0019] As a preferred embodiment of this utility model, the outer perimeter of the stop bar is fitted with a rubber protective sleeve.

[0020] As a preferred embodiment of this utility model, the reset assembly includes a turntable, which is rotatably connected to a fixed column. A push plate is welded to the top of the turntable near the back side, and a fixed plate is welded to the top of the push plate. The fixed plate is rotatably connected to the fixed column.

[0021] The technical effect of adopting the above-mentioned further solution is that by rotating the turntable, the push plate can be driven to rotate around the fixed column, thereby pushing the push plate inward to push the stop bar, causing the inner ends of the two stop bars to approach each other.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] In this invention, the design of the base and adjustment mechanism, along with the coordinated use of the drive assembly, fixed column, and adjustment assembly, allows for height adjustment of the stop lever. The coordinated use of the turntable, push plate, fixed plate, rotating shaft, and magnet allows for rapid inward pushing of the stop lever after use, bringing the inner ends of the two stop levers close together and completing the connection. Compared to traditional training devices, this invention greatly improves ease of use and practicality. Attached Figure Description

[0033] Example 1

[0034] like Figure 1-4 As shown, this utility model provides a technical solution: an adjustable high jump training device for physical education, including a base 1, with adjustment mechanisms 2 symmetrically installed on the top of the base 1 near the left and right sides, a drive assembly 101 installed inside the base 1, and the adjustment mechanism 2 including a fixed column 201 welded to the top of the base 1, an adjustment assembly 202 installed inside the fixed column 201, a crossbar assembly 203 installed on the inner side of the adjustment assembly 202 and located on the inner side of the fixed column 201, and a reset assembly 204 installed on the outer periphery of the fixed column 201.

[0035] Example 2

[0036] like Figure 1-4As shown, the drive assembly 101 includes a connecting rod 1011, which is rotatably connected to the base 1. A first gear 1012 is welded to the outer periphery of the connecting rod 1011 near the left side. A second gear 1013 is meshed with the top of the first gear 1012. A handle 1014 is welded to the top of the second gear 1013, which is rotatably connected to the base 1. A third gear 1015 is welded to the outer periphery of the connecting rod 1011 corresponding to the adjustment mechanism 2. By rotating the handle 1014, the second gear 1013 can be driven to rotate, thereby causing the second gear 1013 to drive the connecting rod 1011 and the third gear 1015 to rotate through the first gear 1012, providing power to the adjustment assembly 202. The force adjustment component 202 includes a lead screw 2021, which is rotatably connected to a fixed column 201. A fourth gear 2022 is fixedly connected to the bottom of the lead screw 2021, extending into the interior of the base 1. The fourth gear 2022 meshes with a third gear 1015. A slider 2023 is sleeved around the lead screw 2021, and a rotating shaft 2024 is fixedly connected to the inner side of the slider 2023. The fourth gear 2022 can drive the lead screw 2021 to rotate following the third gear 1015, thereby allowing the lead screw 2021 to drive the crossbar assembly 203 for height adjustment via the slider 2023 and the rotating shaft 2024. A stop 2025 is welded to the front of the rotating shaft 2024, allowing for height adjustment via the stop 2025. To limit the stop bar 2031 and prevent it from rotating forward, thus improving ease of use, a limiting groove 2011 is provided on the inner side of the fixing post 201 and on the outer periphery of the slider 2023. The limiting groove 2011 limits the movement of the slider 2023, preventing it from rotating helically with the lead screw 2021 and improving stability. The crossbar assembly 203 includes a stop bar 2031. The outer end of the stop bar 2031 is rotatably connected to the rotating shaft 2024. A locking piece 2032 is slidably connected to the inner end of the stop bar 2031. A magnet 2033 is fixedly installed on the inner side of the locking piece 2032, facilitating the fixation of the magnet 2033. When the inner ends of the two stop bars 2031 approach each other... The two magnets 2033 attract each other, which can drive the card 2032 to slide inward, completing the connection of the two crossbar assemblies 203. The outer periphery of the stop bar 2031 is covered with a rubber protective sleeve. The reset assembly 204 includes a turntable 2041, which is rotatably connected to the fixed post 201. A push plate 2042 is welded to the top of the turntable 2041 near the back. A fixed plate 2043 is welded to the top of the push plate 2042. The fixed plate 2043 is rotatably connected to the fixed post 201. By rotating the turntable 2041, the push plate 2042 can be driven to rotate around the fixed post 201, thereby pushing the stop bar 2031 inward and causing the inner ends of the two stop bars 2031 to approach each other.

[0037] The working process of this utility model is as follows: When adjusting the height of an adjustable high jump training device for physical education, firstly, turn the handle 1014, which drives the first gear 1012 to rotate via the second gear 1013. This, in turn, causes the first gear 1012 to drive the third gear 1015 to rotate via the connecting rod 1011. The third gear 1015 then drives the lead screw 2021 to rotate via the fourth gear 2022. The lead screw 2021, through the slider 2023 and the rotating shaft 2024, causes the crossbar assembly 203 to move up and down, thus completing the height adjustment for high jump training. After adjusting to a suitable height, rotate the turntable 2041 inwards, causing it to drive the push plate 2042. Rotating inwards, the push plate 2042 pushes the stop bar 2031 until it is in contact with the stop block 2025. At the same time, the mutual attraction of the two magnets 2033 causes the locking piece 2032 to slide inwards and fit together to complete the connection. When the trainee jumps from the front, once it collides with the stop bar 2031, the stop bar 2031 will rotate in the rear direction under the action of the rotating shaft 2024. The staff can judge the jump performance based on the abnormal movement of the stop bar 2031. Compared with traditional training devices, there is no need for frequent setup actions, and the stop bar 2031 can be quickly reset, which greatly improves the convenience of use and effectively improves the practicality.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
