Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of physical training, in particular to a physical training device for sports. Background Art
[0002] Physical training refers to improving an individual's physical fitness and athletic ability through scientific training methods and plans. Physical fitness includes strength, speed, endurance, agility and flexibility. The goal of physical training is to improve these abilities through systematic training in order to adapt to specific sports or activities. In the process of physical training, some equipment is usually required to assist, so a training device is needed.
[0003] When athletes are doing physical training, they will train their arms and legs. When training their arms, they often use training equipment with weights to drive the weights by stretching the wristbands. After a long period of physical training, a lot of physical energy will be consumed, which can easily lead to physical exhaustion. Traditional physical training equipment does not have a buffer structure. Once athletes become physically exhausted, their arms lose strength and they are likely to loosen the wristbands, causing the weights to be released instantly. This can easily strain the athletes' arms and affect the training effect. Moreover, the weights are in direct and hard contact with the equipment, which can easily damage the training equipment over a long period of time, reducing the service life of the training equipment. Utility Model Content

At this time, under the reaction of the two buffer springs 21, the descending speed of the connecting plate 9 is slowed down, and the connecting plate 9 is initially buffered to prevent the trainer from loosening the ring 15 when losing strength, so that the connecting plate 9 is released instantly to avoid damage to the trainer.

When the trainee performs leg strength training, the airbag 32 will gradually expand. When the bottom of the connecting plate 9 contacts the push rod 30 and pushes the push rod 30 to move downward, under the action of the expanded airbag 32, the descending speed of the connecting plate 9 is slowed down for a second time, further strengthening the protection of the trainee.

Through the action of the two arc grooves 35 and the two limit rods 6, the trainee can increase the number of the counterweight blocks 7 according to his own situation to better adapt to the trainee and enhance the training effect.
[0032] Reference Figure 1 and Figure 3 In a preferred embodiment, baffles 18 are fixed to the inner walls at both ends of the U-shaped frame 4, and the two baffles 18 are located in the middle of the second slide groove 16. Rubber pads 17 are fixed to the tops of the two baffles 18, and the two rubber pads 17 are located below the connecting plate 9. The two rubber pads 17 prevent the connecting plate 9 from having a hard collision with the equipment, thereby extending the service life of the equipment.
[0033] Working principle of this embodiment: During the use of this device, according to the training requirements, a suitable number of counterweights 7 are placed on the top of the connecting plate 9. At this time, the two buffer springs 21 are in a compressed state, and the cooperation of the arc groove 35 and the limit rod 6 facilitates the replacement of the counterweight 7, so as to adjust the weight according to the trainer's situation, thereby increasing the practicality of this device. During training, the trainer sits on the seat 3, steps on the two foot pedals 23 with both feet, and then holds the lifting ring 15 with both hands and pulls the lifting ring 15 with force. The lifting ring 15 drives the connecting plate 9 along the second slide groove 16, thereby driving the multiple counterweights 7 to move upward to perform strength training on the arms. At this time, the two buffer springs 21 in a compressed state gradually return to their original state. While the arms pull the hanging rings 15, the trainee can use both feet to step on the two foot pedals 23 respectively, and cooperate with the connecting rod 22 and the second sliding block 25 to drive the support plate 24 to move along the first slide groove 2 and close to the U-shaped frame 4. At this time, the second spring 27 gradually becomes stretched, which can perform strength training on the trainee's legs. While the support plate 24 moves, the piston 33 is driven along the first slide groove 2 by the piston rod 34. The inner wall of the second sleeve 28 moves, and the air inside the second sleeve 28 can be squeezed into the airbag 32 through the connecting pipe 29, so that the airbag 32 expands. When the airbag 32 expands, it cooperates with the connecting block 31 to drive the push rod 30 to move upward along the first sleeve 8 close to the bottom of the connecting plate 9. When the trainer starts to release multiple counterweights 7 downward, the two first sliders 20 pre-squeeze the two buffer springs 21 that return to their original state. At this time, under the reaction of the two buffer springs 21, the descending speed of the connecting plate 9 is slowed down, and the connecting plate 9 is initially buffered to prevent the trainer from losing strength. The lifting ring 15 will be loosened, so that the connecting plate 9 will be released instantly, avoiding damage to the trainee and improving the training effect. When the bottom of the connecting plate 9 contacts the top rod 30 and pushes the top rod 30 to move downward, the airbag 32 in the expanded state will slow down the descending speed of the connecting plate 9 for a second time, further strengthening the protection of the trainee. When the two ends of the bottom of the connecting plate 9 contact the two rubber pads 17 respectively, the two rubber pads 17 will be squeezed and deformed, avoiding hard collision between the connecting plate 9 and the equipment and extending the service life of the equipment.
