Description

Technical Field

[0001] This utility model belongs to the field of drop protection, specifically, it relates to a drop protection device for lion dance training. Background Technology

[0002] Lion dance, a shining pearl in the long river of Chinese folk art, not only carries a profound cultural heritage and a magnificent national spirit, but its historical lineage can also be traced back to the distant Han Dynasty. After thousands of years of refinement and inheritance, it has not faded, but has become more mellow and prosperous like a fine wine, radiating a lasting and charming brilliance in the tempering of time. In the field of lion dance training, the high difficulty and high dynamic characteristics of the movements objectively bring potential risks of falls to trainees. In order to ensure training safety, fall protection devices have emerged as a key safety guarantee. Their design concept is to significantly reduce the probability of injury when trainees fall accidentally through mechanisms such as cushioning, support, or interception. It is particularly noteworthy that while providing safety guarantees, these devices are also designed to fully consider the actual needs of training, striving not to interfere with trainees' completion of standard professional movements.

[0003] Traditional fall protection devices used in lion dance training often have gaps at the joints of their modular design. These gaps can easily cause the devices to shift during use, which may not only affect the stability of the protection effect but also pose potential safety hazards to the trainees.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0016] like Figures 1 to 6 As shown, the fall protection device for lion dance training includes a base plate 1. The outer surface of the base plate 1 has multiple mounting slots 2. Each set of mounting slots 2 has two electric push rods 3 installed inside. The output end of each set of electric push rods 3 is equipped with a fixing ring 4. The outer surface of each fixing ring 4 has a threaded hole 5. Each set of mounting slots 2 has a motor 6 installed inside. Each set of mounting slots 2 has a fixing plate 7 installed inside. The output end of each motor 6 passes through the fixing plate 7 and is equipped with a threaded rod 8.

[0017] A controller 34 is mounted on the upper surface of the base plate 1. Multiple circular grooves 9 are formed on the bottom surface of the base plate 1. A hydraulic rod 10 is installed inside each circular groove 9, and a roller 11 is mounted on the output end of each hydraulic rod 10. A pad 12 is mounted on the bottom surface of the base plate 1. When the device position needs to be adjusted, the controller 34 activates the hydraulic rod 10, extending its output end and pushing the roller 11 to contact the ground, thus lifting the base plate 1. At this time, the device can be pushed to the designated training area via the roller 11. After reaching the position, the hydraulic rod 10 retracts, the roller 11 returns to the circular groove 9, and the pad 12 on the bottom surface of the base plate 1 contacts the ground. The friction of the pad 12 stabilizes the device, preventing displacement due to collisions during training. A square... A square groove 14 is provided, inside which a sound-absorbing box 15 is installed. A fixing cylinder 28 is installed on the inner bottom wall of the sound-absorbing box 15. A column 29 is slidably installed on the inner wall of the fixing cylinder 28. A fixing block 30 is installed on the outer surface of the column 29. Multiple fixing screws 31 are installed on the upper surface of the fixing block 30. The end of the fixing screw 31 near the fixing block 30 passes through the fixing block 30 and is threaded to the inner wall of the fixing cylinder 28. Tightening the fixing screws 31 on the fixing block 30 allows them to pass through the fixing block 30 and be threaded to the inner wall of the fixing cylinder 28, thus locking the column 29. A foot pedal 32 is installed at the top of the column 29. An anti-slip pad 33 is installed on the upper surface of the foot pedal 32. The foot pedal 32 and the anti-slip pad 33 provide a stable stepping surface for the trainee and prevent slipping.

[0018] The inner bottom wall of the sound-absorbing box 15 is fitted with porous blocks 16, and the upper surface of the base plate 1 is fitted with multiple rubber plates 17. A connecting plate 18 is mounted on the upper surface of the multiple rubber plates 17. Multiple sound-absorbing holes 35 are formed on the upper surface of the connecting plate 18. Collision sounds, equipment noises, etc., generated during training can be processed collaboratively by the sound-absorbing box 15 and the sound-absorbing holes 35. Sound enters the interior of the sound-absorbing box 15 through the sound-absorbing holes 35 on the connecting plate 18, and is reflected and scattered by the porous structure of the porous blocks 16, converting sound energy into heat energy, thereby reducing noise pollution in the training environment and improving training comfort. A protective net 19 is installed on the upper surface of the connecting plate 18. The air cushion 20 serves a restraining function, preventing it from expanding and blocking the sound-absorbing holes 35. An air cushion 20 is installed on the upper surface of the protective net 19. An electrically controlled valve 13 is installed on the outer surface of the air cushion 20. An injection pipe 21 is connected to the outer surface of the air cushion 20. A check valve 22 is installed on the outer surface of the injection pipe 21 to prevent gas backflow. A transmission pipe 23 is connected to the end of the injection pipe 21 furthest from the air cushion 20. A pump body 24 is connected to the end of the transmission pipe 23 furthest from the injection pipe 21. The pump body 24 injects gas into the air cushion 20 through the transmission pipe 23 and the injection pipe 21. The controller 34 can be adjusted via the electrically controlled valve 13. The air pressure inside the air cushion 20 is adapted to the cushioning needs of different weights or drop heights. During a fall, the air cushion 20 absorbs a large amount of impact force through gas compression, reducing the risk of a hard landing. A sponge plate 25 is installed on the upper surface of the air cushion 20, and a support plate 26 is installed inside the sponge plate 25. A protective pad 27 is installed on the upper surface of the support plate 26, and multiple protective blocks 36 are installed on the bottom surface of the protective pad 27. The person falling first comes into contact with the protective pad 27, and the protective blocks 36 on its bottom surface are made of elastic material, which can initially disperse the impact force. At the same time, the sponge plate 25 under the protective pad 27 further cushions the impact through its own deformation.

[0019] Working principle: The controller 34 starts the motor 6, which drives the threaded rod 8 to rotate. The threaded rod 8 is tightly engaged with the threaded hole 5 on the fixed ring 4 at the output end of the electric push rod 3. When the electric push rod 3 extends, it pushes the fixed ring 4 closer to the threaded rod 8. As the fixed ring 4 moves, the threaded rod 8 gradually screws into the threaded hole 5, thus firmly locking multiple protective devices together. This design not only ensures a tight connection between the protective devices, but also effectively solves the gap problem common in traditional modular devices. Conversely, when it is necessary to release the fixation, the motor 6 reverses, and the electric push rod 3 begins to retract. This reverse operation causes the threaded rod 8 to exit from the threaded hole 5, thereby releasing the connection between the fixed ring 4 and the threaded rod 8, and thus loosening multiple protective devices.
