Description

Technical Field

[0001] The invention relates to the technical field of strength training, and in particular to a sprint exercise trainer capable of adjusting antagonistic force. Background Art

[0002] Before a Yaga competition, contestants usually use Yaga sports trainers to train in order to increase their chances of winning. Nowadays, in order to meet the trainers' needs for different training intensities, suppliers have developed Yaga sports trainers with adjustable confrontation intensity.

[0003] Patent publication number CN218248415U discloses a push-up training device, including a base, a mounting box, a plurality of counterweights, a mounting plate and a hydraulic cylinder; horizontally arranged slide grooves are provided on both sides of the base, sliders are correspondingly slidably connected in the two slide grooves, and a training frame is connected between the two sliders; the mounting box is arranged on the side of the base away from the training frame; a plurality of counterweights are slidably mounted in the mounting box, two traction ropes are fixed on the top of the mounting plate, and the hydraulic cylinder is vertically fixed on the bottom of the mounting plate. When using the patented push-up training device for training, the training intensity is first adjusted according to the demand, The training intensity can be adjusted by controlling the number of counterweights hooked on the two L-shaped clamping rods. After the training intensity is adjusted, the trainee stands on the base again and leans forward so that his head passes through the training frame and his shoulders are against the training frame. Then the trainee can put his hands and feet on the ground to perform crawling training. When crawling, the trainee will slide along the slide groove against the training frame and lift the weight through the traction rope, so that strength training can be achieved. This stage is the "pull out" stage, and then in the "come back" stage, the trainee needs to gradually relax his strength as he moves backward. When the training is over, the hooked and raised counterweights will be put down.

[0004] When using the Yajia training device of the above patent for training, if the trainee is exhausted in the "pulling out" stage and cannot bear the weight of the previous heavy object in the "coming back" stage, the training frame will push the trainee backwards under the action of the heavy object. At this time, the trainee may fall due to unstable center of gravity, and then friction will occur on the base, which will pose a safety hazard. In addition, when the traction rope suddenly breaks during training, the trainee will fall because the Yajia training device of the patent is difficult to protect the trainee. In view of the above shortcomings, we have specially designed a Yajia sports trainer with a protective function and adjustable confrontation force. Summary of the invention

A first steel rope 13 is fixedly connected between the front and rear parts of the upper side of the lifting frame 12 and the left side of the movable plate 15. The first steel rope 13 is passed around the adjacent guide wheel 141. A support seat 18 is fixedly connected to the upper right side of the movable plate 15. A rotating member 111 is rotatably connected to the support seat 18. A reset torsion spring 112 is fixedly connected between the rear part of the rotating member 111 and the rear side of the support seat 18. The reset torsion spring 112 is wound around the rear part of the rotating member 111. A second steel rope 19 is wound around the front part of the rotating member 111. A shoulder guard 110 is fixedly installed on the lower right side of the second steel rope 19. A buffer component for buffering the pulling force of the counterweight 16 on the trainee is provided on the front side of the lower right part of the support frame 1.

[0037] like Figure 5 As shown, the buffer assembly includes a support rod 2, a rack 21, a one-way gear 22, a connecting rod 23 and a connecting torsion spring 24. The support rod 2 is fixedly connected to the front side of the lower right part of the support frame 1. The right part of the support rod 2 is rotatably connected to the connecting rod 23. A connecting torsion spring 24 is fixedly connected between the connecting rod 23 and the right front side of the support rod 2. The connecting torsion spring 24 is wound on the connecting rod 23. A one-way gear 22 is fixedly installed on the rear side of the connecting rod 23. The rack 21 is fixedly connected to the front side of the movable plate 15.

[0038] When people need to perform push-up training, they can use the push-up exercise trainer with adjustable antagonistic force to operate. The specific operation is as follows: when in use, the trainee first fixes the traction rope during training on the lower right part of the movable plate 15, and then the trainee adjusts the antagonistic force during training according to his own needs. When adjusting, first manually rotate the limiting screw rod 17 so that the two limiting screw rods 17 move out of the lifting frame 12 to the side away from each other, and then move the limiting screw rod 17 to be flush with the corresponding counterweight block 16, and manually rotate the limiting screw rod 17 in the opposite direction to drive the two limiting screw rods 17 to move to the side close to each other, so that the limiting screw rod 17 is screwed into the corresponding counterweight block 16, so that the number of counterweight blocks 16 lifted by the lifting frame 12 can be adjusted later. The antagonistic force during training, when the antagonistic force is adjusted, the trainee stands on the support plate 11 with his back facing left, and then puts on the shoulder guard 110. After putting on the shoulder guard 110, the trainee puts the traction rope around his neck and passes the traction rope under his crotch. When the traction rope is ready, the trainee lies down again and puts both hands on the support plate 11. When the trainee lies down, since the shoulder guard 110 will move with the trainee, the shoulder guard 110 will pull the second steel rope 19, and then the second steel rope 19 will pull the rotating part 111 to rotate, and then the reset torsion spring 112 will be twisted. When the preparation is completed, the trainee uses his hands and feet to perform crawling training. When the trainee crawls to the right, the trainee will pull the movable plate 15 to the right through the traction rope. , and then the moving plate 15 lifts the lifting frame 12 and the corresponding counterweight 16 upward through the first steel rope 13. This stage is called the "pull out" stage. Subsequently, when the trainee climbs to the right to the limit and gradually relaxes his strength to retreat to the left, the counterweight 16 will move downward under its own gravity, and then the moving plate 15 will be pulled back to the left through the first steel rope 13. This stage is called the "come back" stage. Repeat the above operations to perform the acceleration training. When the acceleration training is over, the trainee needs to take off the shoulder guard 110 and the traction rope. When the shoulder guard 110 is taken off and the second steel rope 19 is no longer pulled, under the action of the reset torsion spring 112, the rotating member 111 will rotate in the opposite direction to reel in the second steel rope 19. If the traction rope suddenly breaks during the training, due to The second steel rope 19 is about to be pulled to the limit, so the second steel rope 19 and the shoulder guard 110 will hang the trainee to prevent the trainee from falling due to inertia, thereby improving the safety during training. At the same time, during training, when the movable plate 15 moves to the left, the movable plate 15 will also drive the rack 21 to move to the right. When the rack 21 moves to the right and engages with the one-way gear 22 and continues to move to the right, the rack 21 will drive the one-way gear 22 to idle, and the one-way gear 22 will not drive the connecting rod 23 to rotate. Then, in the "back" stage, when the movable plate 15 drives the rack 21 to move to the left, the rack 21 will drive the one-way gear 22 to drive the connecting rod 23 to rotate counterclockwise, and then the connecting torsion spring 24 is twisted, which can slow down the speed of the movable plate 15 moving to the left.The movable plate 15 is prevented from quickly pulling the trainee to the left, and the trainee is prevented from falling due to weightlessness due to physical exhaustion, and the safety factor during training is further improved. Then, when the movable plate 15 drives the rack 21 to move to the left and reset, and the rack 21 is no longer engaged with the one-way gear 22, the connecting rod 23 will drive the one-way gear 22 to rotate clockwise and reset under the action of the connecting torsion spring 24. In summary, the safety during the pressing and adding training can be improved.

[0039] Embodiment 2: Based on embodiment 1, Figure 6 , Figure 7 and Figure 8 As shown, the Yajia sports trainer with adjustable resistance force of this embodiment also includes a cleaning component for cleaning sweat and impurities on the support plate 11, and the cleaning component is arranged on the lower right side of the movable plate 15. The cleaning component includes a connecting member 3, and the connecting member 3 is fixedly connected to the lower right side of the movable plate 15. A wiping cotton 31 is fixedly installed on the lower left side of the connecting member 3, and a scraping frame 32 is fixedly connected to the lower right side of the connecting member 3.

[0040] like Figure 6 and Figure 8 As shown, it also includes an auxiliary component for assisting the scraper frame 32 to clean impurities on the support plate 11. The auxiliary component is arranged on the scraper frame 32. The auxiliary component includes a jet component 33. The jet component 33 is fixedly installed on the scraper frame 32. An air tank 34 is fixedly connected to the middle of the rear of the movable plate 15. A piston rod 35 is slidably connected to the air tank 34. A connecting pipe 39 is connected between the air tank 34 and the jet component 33.

[0041] like Figure 6 As shown, it also includes a driving assembly for driving the piston rod 35 to move, the driving assembly is arranged on the piston rod 35, the driving assembly includes a fixing rod 36, the fixing rod 36 is fixedly connected to the top of the piston rod 35, a connecting spring 38 is fixedly connected between the piston rod 35 and the top of the gas tank 34, and an extrusion frame 37 for extrusion matching with the fixing rod 36 is fixedly connected to the rear side of the lower right part of the support frame 1.

[0042] When the trainee sweats profusely during training, the sweat will drip down onto the support plate 11. In order to prevent the trainee's hands and feet from slipping during training, the sweat on the support plate 11 can be wiped off. The specific operation is as follows: when the movable plate 15 moves left and right, the movable plate 15 will also drive the connecting piece 3, the wiping cotton 31 and the scraping frame 32 to move left and right. At this time, the scraping frame 32 will scrape off the impurities on the support plate 11, and the wiping cotton 31 will wipe the sweat and dust on the support plate 11. This can prevent the trainee's hands and feet from slipping during training, thereby improving the stability during training and reducing the occurrence of accidents. At the same time, when the movable plate 15 moves left and right, the movable plate 1 5 will also drive the gas storage tank 34, the piston rod 35 and the fixed rod 36 to move left and right. When the fixed rod 36 moves through the squeezing frame 37, the squeezing frame 37 will intermittently squeeze the fixed rod 36 downward. At this time, under the action of the connecting spring 38, the piston rod 35 and the fixed rod 36 will repeatedly move up and down, so that the jet component 33 can blow air to cool the trainee, thereby improving the coolness of the trainee during training. The jet component 33 can also blow away small stones or impurities on the soles of the trainee's shoes to prevent the trainee from slipping and falling. In summary, during the training process, the impurities and sweat on the upper side of the support plate 11 can be automatically wiped and scraped off to prevent the training effect from being affected.

[0043] like Fig. 9 and Fig.10 As shown, it also includes a deceleration component for slowing down the descent speed of the lifting frame 12. The deceleration component is arranged at the lower left part of the support frame 1. The deceleration component includes an air storage barrel 4. There are two air storage barrels 4. The two air storage barrels 4 are respectively fixed to the front and rear sides of the lower left part of the support frame 1. The lower left side of the air storage barrel 4 is an air outlet. The air storage barrel 4 is slidably connected to a piston frame 43. A connecting frame 41 is fixed between the upper parts of the piston frames 43. The connecting frame 41 and the lifting frame 12 are fixed.

[0044] like Fig.10 As shown, it also includes a linear spring 42 for buffering the piston frame 43, and a plurality of linear springs 42 are fixedly connected between the bottom of the piston frame 43 and the inner bottom wall of the adjacent gas storage barrel 4.

[0045] During the "return" stage, the lifting frame 12 and the counterweight 16 will generate a pulling force on the trainee, pulling the trainee to the left. In order to reduce the pulling force on the trainee, a deceleration component can be used to slow down the descending speed of the lifting frame 12 and the counterweight 16. The specific operation is as follows: initially, the linear spring 42 is in a compressed state. When the trainee climbs to the right and the lifting frame 12 moves upward, the lifting frame 12 will also drive the connecting frame 41 and the piston frame 43 to move upward, and then the linear spring 42 recovers. Then, in the "return" stage, the trainee retreats to the left. When the lifting frame 12, the connecting frame 41 and the piston frame 43 move downward, the linear spring 42 will be compressed, which can buffer the lifting frame 12, the connecting frame 41 and the piston frame 43 moving downward, slowing down the speed of the lifting frame 12 and the counterweight 16 moving downward, and because the air outlet on the air storage barrel 4 is small, the lifting frame 12, the connecting frame 41 and the piston frame 43 will fall downward at a uniform and slow speed, which can further slow down the pulling force exerted by the lifting frame 12 and the counterweight 16 on the trainee, preventing the trainee from being pulled to the left and falling.

[0046] like Fig.11 As shown, it also includes a protection component for cushioning and protecting the trainee, which is arranged on the upper part of the movable plate 15. The protection component includes a buffer frame 5, which is slidably connected to the upper part of the movable plate 15. Buffer springs 51 are fixedly connected between the front and rear sides of the upper part of the buffer frame 5 and the movable plate 15.

[0047] like Fig.11 As shown, a buffer pad 52 is also included for assisting the buffer frame 5 to protect the trainee. The buffer pad 52 is fixed to the right side of the buffer frame 5.

[0048] When the trainee retreats to the left during training, in order to prevent the trainee from hitting the parts on the movable plate 15, the protection component can be used for operation, and the specific operation is as follows: when the trainee is about to hit the parts on the movable plate 15 during the process of retreating to the left, the buffer frame 5 and the buffer pad 52 will intercept the trainee, and the trainee will not be injured when hitting the buffer pad 52. At the same time, when the trainee hits the buffer pad 52, the buffer frame 5 will drive the buffer pad 52 to continuously shake left and right, and then the buffer spring 51 will undergo adaptive deformation, which can buffer the trainee and reduce the impact force when the trainee hits the buffer pad 52. In summary, the trainee can be buffered and protected in the "coming back" stage.

[0049] like Fig.12 and Fig.13As shown, it also includes a slapping assembly for slapping the support plate 11, the slapping assembly is arranged on the upper left side of the support plate 11, the slapping assembly includes a T-shaped rod 64, the T-shaped rod 64 is fixedly connected to the upper left side of the support plate 11, a slapping frame 61 is slidably connected to the T-shaped rod 64, an extrusion spring 65 is fixedly connected between the front and rear parts of the T-shaped rod 64 and the upper side of the slapping frame 61, a connecting column 63 is fixedly connected to the front side of the lower part of the connecting rod 23, an inelastic pull rope 62 is fixedly connected between the connecting column 63 and the front upper side of the slapping frame 61, and a storage frame 6 is placed at the lower part of the support plate 11.

[0050] When the wiping cotton 31 and the scraping frame 32 scrape and wipe the impurities on the support plate 11, some impurities may be stuck in the through holes of the support plate 11. In order to avoid the through holes of the support plate 11 from being blocked, a flapping assembly can be used to flap the support plate 11. The specific operation is as follows: when the connecting rod 23 rotates, the connecting rod 23 will also drive the connecting column 63 to rotate. At this time, the connecting column 63 will intermittently pull the flapping frame 61 upward through the pull rope 62, and the squeezing spring 65 will adaptively deform. In this way, the flapping frame 61 can be repeatedly moved up and down to flap the support plate 11, shake off the impurities stuck in the through holes, and dredge the through holes on the support plate 11. The storage frame 6 will collect the fallen impurities, which can prevent impurities from falling on the ground, making it convenient for people to clean up the impurities later. Then, when the connecting rod 23 stops rotating, the connecting column 63 will also stop rotating. In summary, the through holes on the support plate 11 can be automatically dredged to prevent serious blockage in the through holes.

[0051] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
