[0021] In order to more clearly illustrate the technical solution of the present utility model, the present utility model will be further described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the present utility model. For those of ordinary skill in the art, without creative efforts, other embodiments obtained based on this drawing and embodiment all fall within the protection scope of the present utility model.

[0022] According to Figures 1-5 As shown, a sports equipment training device for upper limb strength training includes a support frame 1. A jack rod 2 is welded to the top of the support frame 1. A first pulley 3 is rotatably installed at the front end of the jack rod 2. A second pulley 4 is rotatably installed at the rear end of the jack rod 2. An inclined support rod 5 is welded to the back of the support frame 1. A slide groove 51 is formed in the inclined support rod 5. A movable pulley block is movably installed in the slide groove 51. A third pulley 6 is arranged at the top end of the support frame 1. A counterweight group 7 is arranged below the third pulley 6. A pulling rope 8 is fixedly connected to the top of the counterweight group 7. The pulling rope 8 is sequentially movably connected to the third pulley 6, the movable pulley block, the second pulley 4, and the first pulley 3. A fixed rod 17 is welded to the front side of the support frame 1. A leg pressing plate 18 is movably installed on the fixed rod 17.

[0023] In this embodiment, the movable pulley block includes a mounting frame 9, which is fitted and mounted in the chute 51. A regulating pulley 10 is rotatably mounted on the mounting frame 9 through a bearing. A first through hole 101 is provided at the axis of the regulating pulley 10. A first fixing pin 11 is fitted and mounted in the first through hole 101. A first anti - detachment portion 111 is provided at the end of the first fixing pin 11. A threaded portion 112 is provided at one end of the first fixing pin 11 away from the first anti - detachment portion 111. A locking nut 12 is fitted and mounted on the threaded portion 112 through threads. A plurality of groups of first limiting holes 52 are provided on the side wall of the chute 51. The first limiting holes 52 are evenly arranged in an array on the inclined support rod 5. The diameter of the first limiting hole 52 is the same as the diameter of the first through hole 101. When fixing the mounting frame 9 on the inclined support rod 5, align the first through hole 101 with the first limiting hole 52. Then, pass the first fixing pin 11 through the first limiting hole 52 and the first through hole 101 to fix the mounting frame 9, and use the locking nut 12 to prevent the first fixing pin 11 from detaching from the inclined support rod 5. A limiting platform 91 is provided at the rear end of the mounting frame 9. When the mounting frame 9 is mounted in the chute 51, the limiting platform 91 abuts against the rear side wall of the inclined support rod 5, and the limiting platform 91 is used to prevent the mounting frame 9 from rotating in the chute 51.

[0024] In this embodiment, a cross bar 13 is fixedly mounted at the top end of the support frame 1. Guide rods 14 are fixedly mounted at the left and right ends of the bottom of the cross bar 13. The weight assembly 7 is slidably mounted on the guide rods 14. Buffer springs 15 are sleeved at both ends of the guide rods 14. The buffer springs 15 are respectively fixedly mounted at the bottom of the cross bar 13 and the bottom end of the support frame 1. Under the action of the pull rope 8, the weight assembly 7 moves up and down along the guide rods 14. When the weight assembly 7 moves to the limit position, the buffer springs 15 absorb the impact force generated by the weight assembly 7, avoiding damage to the support frame 1 due to a large impact.

[0025] In this embodiment, the third pulley 6 is fixedly mounted in the middle of the top of the cross bar 13 through a bearing bracket. A relief hole 131 matching the pull rope 8 is provided in the middle of the cross bar 13. The pull rope 8 passes through the relief hole 131 and is connected to the third pulley 6 and the weight assembly 7. A pull rod 16 is fixedly mounted at one end of the pull rope 8 away from the weight assembly 7. When a fitness person pulls the pull rod 16, the weight assembly 7 is lifted upward through the cooperation of the pull rope 8 and the pulley for exercise.

[0026] In this embodiment, a connecting rod 181 is welded to the center of the bottom of the leg-pressing plate 18. A number of groups of second limiting holes 182 are formed in the connecting rod 181, and the second limiting holes 182 are arranged in an array on the connecting rod 181. A second through hole 171 is formed in the side wall of the fixing rod 17. The diameter of the second through hole 171 matches the diameter of the second limiting hole 182. A second fixing pin 19 is fitted and installed in the second through hole 171. When fixing the leg-pressing plate 18 on the fixing rod 17, the second limiting hole 182 is aligned with the second through hole 171, and then the second fixing pin 19 is passed through the second limiting hole 182 and the second through hole 171 to fix the leg-pressing plate 18. Sponge pads 20 are fixedly installed at the left and right ends of the bottom of the leg-pressing plate 18. A seat cushion 21 is arranged on the front side of the leg-pressing plate 18. The seat cushion 21 is fixedly installed on the support frame 1. The fitness personnel sit on the seat cushion 21 and face the support frame 1 for exercise, and adjust the height of the leg-pressing plate 18 according to their height, so that the leg-pressing plate 18 presses on the thighs of the fitness personnel, thereby improving the versatility of the equipment.

[0027] When the present utility model is in use, the fitness personnel loosen the locking nut 12 and remove the first fixing pin 11 from the inclined support rod 5 before exercise. Then, the position of the mounting bracket 9 is adjusted. When the mounting bracket 9 moves upward along the inclined support rod 5, the pull rod 16 will move downward. The fitness personnel can adjust the height of the pull rod 16 according to their own height. Therefore, the fitness personnel can hold the pull rod to start exercise without standing, which is convenient to use and reduces the risk of personnel injury. In addition, when the fitness personnel sit on the seat cushion 21 and are ready to exercise, the second fixing pin 19 can be pulled out from the fixing rod 17. At this time, the height of the leg-pressing plate 18 can be adjusted according to their own height, which is beneficial to improving the versatility of the equipment.

[0028] The above embodiments are only exemplary embodiments of the present utility model and are not used to limit the present utility model. The protection scope of the present utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present utility model, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present utility model.
