Description

[0002] When gymnasts are training on the horizontal and parallel bars, they often drop their hands accidentally, and the athlete's head or neck may directly contact the cushioning pad. Although the soft sponge pad has a certain cushioning effect, there is also a certain probability of causing irreversible damage to the athlete. If an air cushion is placed on the top of the sponge pad, the distance between the horizontal and parallel bars and the air cushion will be shortened, and the athlete's feet will contact the air cushion when doing training movements, causing obstruction. If the height of the horizontal bar is increased and an air cushion is placed, the impact force after the athlete drops the hands and falls will increase, resulting in a decrease in protection efficiency.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0019] A protective device for gymnastics training, see Figure 1-Figure 3 , including a guide device 1, a bottom plate 2 is fixedly installed on both sides of the outer surface of the guide device 1 near the bottom, an air chamber 3 is provided on the top of the bottom plate 2 near the outer side, and an elastic skin 4 is provided on the top of the air chamber 3. An elastic support structure 5 is fixedly installed on the top of the bottom plate 2, and a sponge buffer pad 6 is fixedly installed on the top of the elastic support structure 5, which mainly plays a basic buffering effect. The elastic force of the elastic support structure 5 itself will lift the sponge buffer pad 6, reducing the distance between the sponge buffer pad 6 and the elastic skin 4. The sponge buffer pad 6 is movably sleeved inside the air chamber 3, and a stroke device 7 is movably installed on the top of the guide device 1.

[0020] See also Figure 1-Figure 3 In the initial state, there is a gap between the top of the sponge buffer pad 6 and the air chamber 3, and the top of the sponge buffer pad 6 is in contact with the bottom surface of the elastic skin 4 in the initial state.

[0021] When the elastic skin 4 expands under the high-pressure gas, the sponge cushion 6 will also move downward under the action of the high pressure. At the same time, the elastic support structure 5 stores the spring force, leaving enough space for the gas to expand, thereby avoiding the elastic skin 4 from expanding to too high a height. As a result, after the athlete loses his grip due to a flipping action, the elastic skin 4 is too high, causing the elastic skin 4 to drop too slowly during subsequent deflation and come into contact with the athlete's footsteps, thereby improving the reliability of the device.

[0022] See also Figure 4-Figure 5 The flow guide device 1 includes a transverse tube 11. A left vertical tube 12 and a right vertical tube 13 are provided at the top of the transverse tube 11 near both ends. The left vertical tube 12 and the right vertical tube 13 are connected to the inner cavity of the transverse tube 11. A pressure sensor 14 is provided at the bottom of the inner wall of the transverse tube 11 and at positions corresponding to the left vertical tube 12 and the right vertical tube 13. Side through holes 15 are provided on the inner sides of the left vertical tube 12 and the right vertical tube 13 near the top. An air flow hole 16 is provided on the outer side of the left vertical tube 12 near the middle. The air flow hole 16 is connected to the air pump. A limit device 17 is provided on the outer side of the left vertical tube 12 below the air flow hole 16. A buzzer device 18 is provided at one end of the transverse tube 11. See also Figure 2 and Figure 4-Figure 5 , the stroke device 7 is movably installed inside the left vertical tube 12 and the right vertical tube 13; See also Figure 5 The output end of the pressure sensor 14 is connected to the input end of the air pump through a signal connection, and the operating power of the air pump is adjusted.

[0023] See also Figure 5 The limiting device 17 includes a shell 171, which is connected to the inner cavity of the transverse tube 11. A spring clip 172 is provided inside the shell 171. The end of the spring clip 172 is connected to the inner wall of the shell 171 through a spring. A pull rod 173 is provided at the end of the spring clip 172. The pull rod 173 passes through the shell 171 and extends to the outside. See also Figure 5 The front end of the spring buckle 172 is provided with a bevel buckle, and the bevel buckle extends into the interior of the left vertical tube 12.

[0024] See also Figure 5 , characterized in that the buzzer device 18 includes a travel chamber 181, a buzzer 182 is provided on the top of the travel chamber 181, and a baffle 183 is provided at one end of the inner wall of the travel chamber 181; See also Figure 5 In the initial state, the baffle 183 blocks one end of the travel chamber 181.

[0025] When the athlete performs gymnastics training normally, the air flow generated by the operation of the air pump enters the interior of the transverse tube 11, pushes the baffle 183 to the right and enters the interior of the stroke chamber 181, and is discharged from the inside of the baffle 183, thereby causing the buzzer 182 to produce a buzzing sound. When the athlete accidentally drops the hand or the training is over, the buzzing sound will stop, thereby serving as a reminder to the coach, increasing the practicality of the device.

[0026] See also Figure 6 The stroke device 7 includes a transverse rod 71, and support rods 72 are respectively provided at both ends of the transverse rod 71. The bottom of the support rod 72 is fixedly mounted with an adjustment device 73 and an exhaust device 74; See also Figure 5-Figure 6 The regulating device 73 and the exhaust device 74 are movably installed inside the left vertical pipe 12 and the right vertical pipe 13 respectively.

[0027] When the gymnast changes, the athlete grabs the horizontal rod 71 to move the adjustment device 73 and the exhaust device 74 downward and squeeze the pressure sensor 14. At this time, the pressure sensor 14 will sense the pressure and adjust the operating power of the air pump. When the pressure sensed by the pressure sensor 14 is large, the operating power of the air pump will also increase, thereby ensuring that the expansion speed and volume of the elastic skin 4 are proportional to the weight of the gymnast, ensuring that the device can adopt the most efficient and effective protection measures for athletes of different weights, further improving the practicality of the device.

[0028] See also Figure 7-Figure 8 The adjusting device 73 includes an adjusting chamber 731, and a first upper bracket 732 and a first lower bracket 733 are respectively provided at the top and bottom of the adjusting chamber 731. The support rod 72 on the right is fixedly connected to the top of the first upper bracket 732. The front of the adjusting chamber 731 is respectively provided with a first through hole 734, a connecting pipe 735 and a second through hole 736. The inner cavity of the adjusting chamber 731 is provided with a guide chamber 737. A guide hole 738 is provided on the back of the adjusting chamber 731 near the top. The first through hole 734 is connected to the second through hole 736 through a pipe. A card slot 739 is provided on the front of the adjusting chamber 731 below the connecting pipe 735. The bottom of the first lower bracket 733 is provided with a first bottom through hole 730. See also Figure 5 and Figure 7-Figure 8 A circular hole is opened at the bottom of the first lower bracket 733, and the first lower bracket 733 is connected to the bottom of the inner wall of the transverse tube 11 through a spring.

[0029] See also Figure 9The exhaust device 74 includes an exhaust chamber 741. The top and bottom of the exhaust chamber 741 are both provided with a second upper bracket 742 and a second lower bracket 743. The left support rod 72 is fixedly connected to the top of the second upper bracket 742. Exhaust holes 744 are provided on the inner side of the exhaust chamber 741 near the top and bottom. See also Figure 5 and Figure 9 A circular hole is opened at the bottom of the second lower bracket 743, and the second lower bracket 743 is connected to the bottom of the inner wall of the transverse tube 11 through a spring.

[0030] See also Figure 9 In the initial state, the second through hole 736 is connected with the right through hole 15, and the exhaust hole 744 is in a corresponding state with the left side through hole 15. The inclined buckle at the front end of the spring buckle 172 cooperates with the guide chamber 737 to lock the rear through hole 15 and connect it with the connecting pipe 735, and the exhaust hole 744 and the left side through hole 15 are in a staggered and closed state. When the support rod 72 presses down the side through hole 15 to connect it with the first through hole 734, the exhaust hole 744 and the left side through hole 15 are in a staggered and closed state. At the same time, the bottom of the first lower bracket 733 and the first through hole 734 are in contact with the pressure sensor 14.

[0031] When the gymnast grabs the transverse rod 71 with both hands, the stroke device 7 is pressed down as a whole under the action of gravity, so that the adjustment device 73 and the exhaust device 74 move downward inside the left vertical tube 12 and the right vertical tube 13. At the same time, the bottom of the first lower bracket 733 and the bottom of the second lower bracket 743 contact the pressure sensor 14. If the athlete accidentally drops the hands, the spring releases its elastic force and lifts up the stroke device 7 as a whole. In the process of the adjustment device 73 and the exhaust device 74 moving upward, the spring clip 172 extends under the action of the elastic force, and the inclined clip at the front end of the spring clip 172 is locked with the slot 739. At this time, the side through hole 15 is connected with the connecting pipe 735, and The exhaust hole 744 and the side through hole 15 on the left are in a staggered and closed state, which allows the high-pressure gas generated by the air pump to enter the interior of the guide chamber 737 through the connecting pipe 735, and enter the area between the elastic skin 4 and the sponge cushion 6 through the guide hole 738. Under the action of the high-pressure gas, the elastic skin 4 expands rapidly and first contacts the falling athlete to perform a buffering. After the buffering capacity of the gas inside the elastic skin 4 is released, the athlete contacts the sponge cushion 6 again, thereby avoiding the problem that the athlete falls in an inverted posture, the head or neck directly contacts the sponge cushion 6 and is injured under the action of the impact force, thereby improving the safety of the device.

[0032] When an athlete performs a difficult flipping action, the elastic skin 4 may be released. At this time, the elastic skin 4 will also expand under the action of the high-pressure gas. As the athlete completes the flipping action, the athlete grabs the transverse rod 71 again to press the support rod 72 downward. At this time, under the action of gravity, the adjustment device 73 and the exhaust device 74 move downward. When the side through hole 15 is connected to the first through hole 734, the top exhaust hole 744 and the left side through hole 15 are in a corresponding state. At the same time, the bottom of the first lower bracket 733 and the first through hole 734 are in contact with the pressure sensor 14. At this time, the high-pressure gas enters the interior of the transverse tube 11 through the first through hole 734 and is discharged from the buzzer device 18, thereby generating a negative pressure inside the transverse tube 11, so that the gas between the elastic skin 4 and the sponge cushion 6 enters the interior of the transverse tube 11 through the side through hole 15, the exhaust hole 744 on the top and the second bottom through hole 745, so that the elastic skin 4 in the inflated state is quickly deflated, preventing the athlete's feet from coming into contact with the elastic skin 4 in the inflated state during normal gymnastics training, thereby improving the stability of the device in operation.

[0033] When the athlete finishes training and lands normally, the elastic skin 4 is always in an expanded state because the inclined buckle at the front end of the spring buckle 172 is in a state of being engaged with the slot 739. At this time, it is only necessary to pull the pull rod 173 outward to release the inclined buckle at the front end of the spring buckle 172 from being engaged with the slot 739. Under the action of the spring force, the adjusting device 73 and the exhaust device 74 move upward, so that the second through hole 736 is connected to the right through hole 15, and the exhaust hole 744 at the bottom is in a corresponding state with the left side through hole 15. The gas between the elastic skin 4 and the sponge cushion 6 enters the interior of the transverse tube 11 through the exhaust hole 744 and the second bottom through hole 745, and is discharged from the buzzer device 18, thereby completing the deflation effect of the elastic skin 4, ensuring that the athlete will not be hindered by the elastic skin 4 in the expanded state when he needs to perform gymnastics training again, thereby improving the practicality of the device.

[0034] The method of use of the present invention is as follows: During use, the gymnast grasps the transverse rod 71 with both hands, and the stroke device 7 is pressed down as a whole under the action of gravity, so that the adjustment device 73 and the exhaust device 74 move downward inside the left vertical tube 12 and the right vertical tube 13. At the same time, the bottom of the first lower bracket 733 and the bottom of the second lower bracket 743 contact the pressure sensor 14. If there is a dangerous situation in which the athlete accidentally drops his hands, the spring releases the elastic force and lifts up the stroke device 7 as a whole. In the process of the adjustment device 73 and the exhaust device 74 moving upward, the spring clip 172 extends under the action of the elastic force, and the inclined clip at the front end of the spring clip 172 is locked with the slot 739. At this time, the side through hole 15 is connected with the connecting pipe 735, and the exhaust hole 744 is in a staggered sealed state with the side through hole 15 on the left. The closed state allows the high-pressure gas generated by the air pump to enter the interior of the guide chamber 737 through the connecting pipe 735, and enter the area between the elastic skin 4 and the sponge cushion 6 through the guide hole 738. Under the action of the high-pressure gas, the elastic skin 4 expands rapidly and first contacts the falling athlete to perform a buffer. After the buffering capacity of the gas inside the elastic skin 4 is released, the athlete contacts the sponge cushion 6 again. When the athlete performs a difficult flip, the elastic skin 4 will normally fall out of the hand. At this time, the elastic skin 4 will also expand under the action of the high-pressure gas. As the athlete completes the flip, the athlete grabs the transverse rod 71 again to press the support rod 72 downward. At this time, the adjusting device 73 and the exhaust device 74 move downward under the action of gravity. When the side through hole 15 is connected to the first through hole 734, the exhaust hole 744 on the top is in a corresponding state with the side through hole 15 on the left. At the same time, the first lower bracket 733 and the bottom of the first through hole 734 are in contact with the pressure sensor 14. At this time, the high-pressure gas enters the interior of the transverse tube 11 through the first through hole 734 and is discharged from the buzzer device 18, thereby generating a negative pressure inside the transverse tube 11, so that the gas between the elastic skin 4 and the sponge cushion 6 enters the interior of the transverse tube 11 through the side through hole 15, the exhaust hole 744 on the top and the second bottom through hole 745, thereby quickly deflating the elastic skin 4 in the inflated state, avoiding the athlete's feet from contacting the elastic skin 4 in the expanded state during normal gymnastics training. When the elastic skin 4 is expanded by the high-pressure gas, the sponge cushion 6 will also move downward under the action of the high pressure. At the same time, the elastic support structure 5 stores the spring force, thereby leaving enough space for the gas to expand, thereby preventing the elastic skin 4 from being too high after expansion, resulting in the problem that after the athlete loses his grip due to a flipping action, the elastic skin 4 is too high, causing the elastic skin 4 to drop too slowly during subsequent deflation and come into contact with the athlete's footsteps. When the athlete finishes training and lands normally after jumping forward, the inclined buckle at the front end of the spring buckle 172 is in a state of being engaged with the slot 739, so that the elastic skin 4 is always in an expanded state. At this time, it is only necessary to pull the pull rod 173 outward to release the inclined buckle at the front end of the spring buckle 172 from being engaged with the slot 739.Under the action of the spring force, the regulating device 73 and the exhaust device 74 move upward, so that the second through hole 736 is connected to the right through hole 15, and the exhaust hole 744 at the bottom is in a corresponding state with the side through hole 15 on the left. The gas between the elastic skin 4 and the sponge cushion 6 enters the interior of the transverse tube 11 through the exhaust hole 744 and the second bottom through hole 745, and is discharged from the buzzer device 18, thereby completing the deflation effect of the elastic skin 4, ensuring that when the athletes need to perform gymnastics training again, they will not be hindered by the elastic skin 4 in the expanded state. When the athletes perform gymnastics training normally, the airflow generated by the operation of the air pump enters the interior of the transverse tube 11, pushes the baffle 183 to move right and enters the interior of the travel chamber 181, and is discharged from The air inside the baffle 183 is discharged, causing the buzzer 182 to sound. If an athlete accidentally drops the grip or after training, the buzzer stops, thus serving as a reminder to the coach. When the gymnast changes, the athlete grasps the transverse rod 71, causing the adjustment device 73 and the exhaust device 74 to move downward and squeeze the pressure sensor 14. The pressure sensor 14 then senses the pressure and adjusts the operating power of the air pump. When the pressure sensed by the pressure sensor 14 is high, the operating power of the air pump is also increased, thereby ensuring that the expansion speed and volume of the elastic skin 4 are proportional to the gymnast's weight, ensuring that the device can adopt the most efficient and effective protection measures for athletes of different weights.
