Description

Technical Field

[0001] This utility model relates to the field of long jump testing instruments, and more particularly to a standing long jump testing instrument. Background Technology

[0002] The standing long jump tester is a specialized sports testing device used to measure the performance of a person in the standing long jump. It mainly uses specific detection principles and structural design to accurately capture the take-off point, landing point, or related motion data of the test subject during the standing long jump, and then automatically calculates and displays the jump distance. It is widely used in school physical education teaching assessment, physical health monitoring, sports training evaluation, and other scenarios. It can provide objective and accurate quantitative basis for judging the test subject's lower limb explosive power, body coordination, and other physical fitness indicators. Some devices also have data storage, transmission, and statistical analysis functions to meet the testing and data management needs in different scenarios.

[0003] The standing long jump tester is a commonly used device in physical education and physical fitness monitoring for accurately measuring standing long jump performance. While the operational details vary slightly between different models, the core usage process remains the same. Before use, thorough preparation is essential. First, ensure the tester is powered on, the display is lit, and there are no error messages. For photoelectric testers, check that the take-off line and sensor rod are aligned and unobstructed. For mechanical pointer testers, ensure the scale is flat and the pointer can return to its normal position. Then, lay out the test mat, ensuring it covers the take-off area to the landing area without wrinkles. Ensure the take-off line is clearly visible, the landing area is flat, and there are no obstacles around. The tester should wear appropriate sportswear and non-slip sports shoes and remove any hard objects from pockets. Follow the prescribed testing procedures. Finally, pay attention to relevant precautions to ensure accurate and safe testing.

[0004] Commercially available standing long jump testers lack reliable locking mechanisms. Locking mechanisms are prone to loosening, causing the carpet to shift during testing. Locking operations are complex, requiring multiple adjustments to secure the carpet. Over time, the locking function deteriorates, and the fixing effect decreases with repeated use. The linkage between the locking mechanism and the unfolding mechanism is poor, requiring separate operation and adding steps. The unlocking process is cumbersome, and carpet retrieval is time-consuming. Locking components are prone to wear, affecting the overall lifespan of the device. Therefore, a standing long jump tester is proposed to solve the above problems. Summary of the Invention

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Reference Figures 1-3The present invention provides an embodiment of a standing long jump testing instrument, comprising a fixed outer shell 1, inside which are an unfolding mechanism 2 and a disassembly mechanism 3. The unfolding mechanism 2 includes a rotating rod 216, which drives the fixed shell 214 to rotate synchronously, providing the flipping power for the unfolding of the rotating shell 217 and the carpet 218. The fixed shell 214 is fixedly connected to the outer wall of the rotating rod 216, and the fixed shell 214 carries the rotating rod 311 and the rotating shell 217. The rotating rod 311 drives the rotating shell 217 to unfold. It is the core component connecting the rotating rod 216 and the rotating housing 217. The inner wall of the fixed housing 214 rotates and is slidably connected to the rotating rod 311. The rotating rod 311 connects the fixed housing 214 and the rotating housing 217, transmits the flipping force of the fixed housing 214, and can slide along the rotating housing 217. It works with the disassembly mechanism 3 to separate the components. The outer wall of the rotating rod 311 rotates and is slidably connected to the rotating housing 217. The rotating housing 217 flips to a horizontal position with the rotating rod 311, supporting the rotating column 219, the carpet 218, and the locking pin 2. Components 20 provide installation and support space for the unfolding of carpet 218. A rotating column 219 is rotatably connected to the inner wall of the rotating outer shell 217. The rotating column 219 can rotate within the rotating outer shell 217 and wraps around the outer wall of carpet 218. The unfolding and retraction of carpet 218 is achieved through rotation, making it the core actuator for unfolding carpet 218. A locking pin 220 is slidably connected to the inner wall of the rotating outer shell 217. The locking pin 220 is pulled and rotated by the operator, driving the sliding shell 221 and the ring gear 222 to move, thus controlling the ring gear 222. Engaging or disengaging with the ring sleeve 223 locks and unlocks the rotating column 219. The side wall of the locking pin 220 is rotatably connected to the sliding shell 221. The sliding shell 221 moves with the locking pin 220, driving the ring gear 222 to slide synchronously, providing sliding support for the engagement and switching of the ring gear 222 and the ring sleeve 223. The outer wall of the sliding shell 221 is fixedly connected to the ring gear 222. Under the elastic force of the spring 225, the ring gear 222 can engage with the ring sleeve 223, locking the position of the rotating column 219 to prevent the carpet 218 from sliding.When the locking pin 220 disengages, the rotating column 219 is allowed to rotate, allowing the carpet 218 to unfold. A fixed column 224 is elastically connected to the inner wall of the ring gear 222 via a spring 225. The fixed column 224 is fixed to the outer wall of the rotating housing 217 via a fixed bracket 226, providing fixed support for the spring 225 and ensuring the elastic reset function of the ring gear 222. The spring 225 connects the ring gear 222 and the fixed column 224, providing elastic thrust to keep the ring gear 222 engaged with the ring sleeve 223, ensuring a stable locking state after the carpet 218 is unfolded. The outer wall of the ring gear 222 is engaged with the ring sleeve 223, which is fixed to the side wall of the rotating column 219. When engaged with the ring gear 222, the ring sleeve locks the rotating column 219; when disengaged, it rotates synchronously with the rotating column 219, thus controlling the unfolding of the carpet 218. The sidewall of the gear sleeve 223 is fixedly connected to the sidewall of the rotating column 219. A carpet 218 is wrapped around the outer wall of the rotating column 219. The carpet 218 is wrapped around the outer wall of the rotating column 219 and gradually unfolds as the rotating column 219 rotates, forming a dedicated area for the standing long jump test and providing a standard test site. A bidirectional threaded rod 211 is rotatably connected to the inner wall of the fixed housing 1. The bidirectional threaded rod 211 is driven to rotate by the second helical gear 229. On the one hand, it drives the first gear 212 to rotate, providing power for the rotation of the rotating rod 216; on the other hand, it drives the sliding block 215 to slide through the threaded sleeve, realizing the position adjustment of the moving block 215. The outer wall of the bidirectional threaded rod 211 is threadedly connected to the moving block 215 through the threaded sleeve. The moving block 215 slides along the inner wall of the fixed housing 1 and is driven by the bidirectional threaded rod 211 to adjust its position. This can adapt to the auxiliary fixing needs in different test scenarios and improve test stability.

[0020] Reference Figures 2-4The unfolding mechanism 2 also includes a gear 212, which rotates with the bidirectional threaded rod 211 and meshes with a second gear 213, transmitting the rotational power of the bidirectional threaded rod 211 to the rotating rod 216, thus changing the direction of power. The inner wall of the gear 212 is fixedly connected to the outer wall of the bidirectional threaded rod 211, and the outer wall of the gear 212 is meshed with the second gear 213. The second gear 213 meshes with the gear 212, driving the rotating rod 216 to rotate synchronously, transmitting power to the rotating rod 216, and driving the fixed shell 214 to rotate. The inner wall of the second gear 213 is fixedly connected to the outer wall of the rotating rod 216. The unfolding mechanism 2 also includes a motor 227, which is fixed to the inner wall of the fixed shell 1, providing the core power for the unfolding mechanism 2. The output shaft... The helical gear 228 rotates, driving the subsequent transmission components to move in tandem. The outer wall of the motor 227 is fixedly connected to the inner wall of the fixed housing 1. The output shaft of the motor 227 is fixedly connected to the helical gear 228. The helical gear 228 rotates with the output shaft of the motor 227, meshing with the helical gear 229 to achieve a change in the direction of power, transmitting the power of the motor 227 to the bidirectional threaded rod 211. The outer wall of the helical gear 228 is meshed with the helical gear 229. The helical gear 229 meshes with the helical gear 228, driving the bidirectional threaded rod 211 to rotate synchronously, transmitting the power to the bidirectional threaded rod 211. The inner wall of the helical gear 229 is fixedly connected to the outer wall of the bidirectional threaded rod 211. Both ends of the rotating rod 216 are rotatably connected to the inner wall of the fixed housing 1.

[0021] Reference Figures 3-5The disassembly mechanism 3 includes a cylindrical tube 314, which is slidably and rotatably connected to the rotating rod 311. It is engaged with the fixed shell 214 by the elastic force of spring 313, maintaining a stable connection between the rotating shell 217 and the fixed shell 214. During disassembly, the engagement disengages with the action of the lever 312, and the inner wall of the cylindrical tube 314 rotates and slides with the outer wall of the rotating rod 311. The disassembly mechanism 3 also includes a lever 312, which is pinched and slidably by the operator, causing the rotating rod 311 to slide along the rotating shell 217, releasing the engagement between the cylindrical tube 314 and the fixed shell 214, or causing the rotating shell 217 to disengage from the rotating rod 311. This lever is the core triggering component for the disassembly operation. The side wall of the rotating rod 311 is fixedly connected to the side wall of the lever 312, and the side wall of the lever 312 is elastically connected to the inner wall of the cylindrical tube 314 by spring 313. The spring 213 connects the lever 312 and the cylindrical tube 314, providing elastic thrust to ensure that the cylindrical tube 314 is always tightly fitted with the fixed shell 214, thus ensuring the stable connection between the rotating shell 217 and the fixed shell 214. During disassembly, it is compressed; during assembly, it resets and pushes the components together. The outer wall of the lever 312 is slidably connected to the inner wall of the cylindrical tube 314, and the lever 312 is also slidably connected to the inner wall of the rotating shell 217. One end of the spring 225 is fixedly connected to the side wall of the ring gear 222, and the other end is fixedly connected to the inner wall of the fixed column 224. A fixed bracket 226 is fixedly connected to the outer wall of the fixed column 224, supporting the fixed column 224 and providing a stable mounting base for the spring 225 and the ring gear 222, ensuring the reliable function of the locking mechanism. The outer wall of the fixed bracket 226 is fixedly connected to the outer wall of the rotating outer shell 217, one end of the second spring 313 is fixedly connected to the side wall of the lever 312, and the other end of the second spring 313 is fixedly connected to the inner wall of the cylindrical tube 314.

[0022] Working principle: When motor 227 starts, it drives helical gear 1 228 to rotate. Helical gear 1 228 meshes with and drives helical gear 229, causing the bidirectional threaded rod 211 to rotate synchronously. The bidirectional threaded rod 211 drives gear 1 212 to rotate. Gear 1 212 meshes with and drives gear 213, causing the rotating rod 216 to rotate. The rotating rod 216 causes the fixed shell 214 to flip. The fixed shell 214, through the rotating rod 311, causes the rotating outer shell 217 to unfold to a horizontal state. At the same time, it pulls and rotates the locking pin 220, causing the ring gear to... Under the elastic force of spring 225, 222 disengages from the ring sleeve 223. The ring sleeve 223 drives the rotating column 219 to rotate, gradually unfolding the carpet 218 wrapped around the outer wall of the rotating column 219 to form the standing long jump test area. Rotating the locking pin 220 again can lock the carpet 218 to prevent slippage. When the bidirectional threaded rod 211 rotates, it drives the moving block 215 to slide along the inner wall of the fixed housing 1 through the threaded sleeve. The position of the moving block 215 can be adjusted to adapt to the auxiliary fixing requirements of different test scenarios.

[0023] Squeeze the lever 312 to slide the rotating rod 311 along the inner wall of the rotating housing 217, causing the rotating housing 217 to disengage from the fixed housing 214. Squeeze the lever 312 again to disengage the rotating housing 217 from the rotating rod 311, making it convenient to inspect or replace components such as the rotating column 219 and carpet 218 inside the rotating housing 217. To reassemble the components, reinsert the rotating rod 311 into the inner wall of the fixed housing 214, release the lever 312, and the spring 313 will reset, pushing the cylindrical tube 314 to re-engage with the fixed housing 214 and restore the equipment to its working state.
