[0002] People are paying more and more attention to their physical health. At the same time, upper limb training is also very important. Sports equipment is an important tool for exercise, fitness, and rehabilitation. The use of sports equipment can help people train their upper limbs, strengthen their own strength, increase muscle circumference, shape or change their own muscle shape, and improve their physical fitness.

[0003] With existing upper limb strength training devices, it is difficult for trainees to perform upper limb training smoothly under the action of the counterweight, which causes the force points of the muscles to constantly change during upper limb exercises, affecting the training effect. In addition, when trainees add counterweights to increase the intensity of training according to their own conditions, the counterweights fall too quickly, which can easily cause the counterweight components to come into hard contact with the device, causing injuries to the trainees' arms.

A sliding frame 2 is fixedly connected between the upper parts of the two base frames 1. Two counterweight frames 3 are slidably connected to the sliding frame 2. The counterweight frames 3 are used to load counterweight blocks. The sliding frame 2 is located above the base frame 1. Four fixed rods 4 are fixedly connected to the upper part of the sliding frame 2. The four fixed rods 4 are rotatably connected to rotating wheels 5. The two rotating wheels 5 on the same side form a group, and each group of rotating wheels 5 is located above the counterweight frame 3. A buffer assembly is provided on the base frame 1. The buffer assembly is used to slow down the moving speed of the pull rod 14 to avoid direct hard contact between the pull rod 14 and the device, thereby protecting the trainee's arms. A stretching assembly is provided on the sliding frame 2. The stretching assembly is used for the trainee to perform upper limb training, so that the trainee can perform upper limb training more smoothly after increasing the training intensity according to his own situation, thereby achieving better training effect.

[0021] The buffer assembly includes a hydraulic cylinder 1 6, a push rod 7, a return spring 8, a fixed frame 9, a hydraulic cylinder 2 10 and an infusion tube 101. The tops of the two base frames 1 are fixedly connected to the hydraulic cylinder 1 6, and the hydraulic cylinder 1 6 is filled with hydraulic oil. The two hydraulic cylinders 1 6 are slidably connected with push rods 7, and the push rods 7 are used to buffer the counterweight frame 3. A return spring 8 is connected between the push rod 7 and the hydraulic cylinder 1 6. The upper parts of the two base frames 1 are fixedly connected to the fixed frames 9, and the two fixed frames 9 are fixedly connected to the hydraulic cylinder 2 10, and the hydraulic cylinder 2 10 is filled with hydraulic oil. A vent is provided on the top of the hydraulic cylinder 2 10. The lower parts of the two hydraulic cylinders 2 10 are fixedly connected to the infusion tube 101, and the hydraulic cylinder 2 10 is communicated with the infusion tube 101. The end of the infusion tube 101 away from the hydraulic cylinder 2 10 is fixedly connected to the hydraulic cylinder 1 6, and the infusion tube 101 is communicated with the hydraulic cylinder 1 6.

[0022] The stretching assembly includes a guide frame 11, a sliding rod 12, a pull rope 13 and a pull rod 14. The upper part of the sliding frame 2 is fixedly connected to the two guide frames 11, and sliding grooves are opened on the two guide frames 11. The sliding rod 12 is slidably connected between the two guide frames 11. The lower parts of the two counterweight frames 3 are fixedly connected to the pull rope 13. The end of the pull rope 13 away from the counterweight frame 3 is fixedly connected to the slide rod 12. The pull rope 13 passes around each group of rotating wheels 5. The side of the slide rod 12 away from the sliding frame 2 is fixedly connected to the pull rod 14.

[0023] The guide frame 11 is used to provide guidance for the slide bar 12 .

[0024] In actual use, before performing upper limb training, the trainee can add or reduce counterweight blocks in the counterweight frame 3 according to his own situation to increase the training intensity, thereby improving the training effect. Then the trainee holds the pull rod 14 and pulls it down. The downward movement of the pull rod 14 will drive the sliding rod 12 to slide downward, and the sliding rod 12 can move smoothly downward between the two guide frames 11. The downward movement of the sliding rod 12 will drive the two pull ropes 13 to slide on the rotating wheel 5, and pull the two counterweight frames 3 with the counterweight blocks placed thereon upward. The two counterweight frames 3 with the counterweight blocks placed thereon will slide upward along the sliding frame 2, and the counterweight frames 3 will be out of contact with the push rod 7. The two counterweight frames 3 with the counterweight blocks placed thereon will produce a certain resistance. Then the trainee moves the pull rod 14 upward, and the upward movement of the pull rod 14 will drive the sliding rod 12 moves upward, and the slide bar 12 can move upward smoothly between the two guide frames 11. The upward movement of the slide bar 12 will drive the two counterweight frames 3 with counterweight blocks placed thereon to move downward, so that the trainee can perform upper limb training more smoothly and achieve better training effects. The counterweight frames 3 move downward and contact with the push rod 7, and the reset spring 8 is compressed. The downward movement of the push rod 7 will push the liquid in the hydraulic cylinder 1 6 to slowly flow into the hydraulic cylinder 2 10 through the infusion tube 101, thereby buffering the counterweight frame 3 with counterweight blocks, so that the trainee can pull the pull rod 14 upward to slow down the moving speed of the pull rod 14 and avoid direct hard contact between the pull rod 14 and the device, thereby protecting the trainee's arm. In this way, the trainee continuously pulls the pull rod 14 up and down to perform upper limb strength training.

[0025] Embodiment 2: Based on embodiment 1, Figure 2 and Figure 3 As shown, it also includes a push plate 15 and a limit block 16. The push plates 15 are slidably connected to the two counterweight frames 3. The push plates 15 are used to push the counterweight blocks to move. The upper parts of the two counterweight frames 3 are fixedly connected to two limit blocks 16. The limit blocks 16 are used to limit the push plates 15.

[0026] When the trainee continuously pulls the pull rod 14 up and down to perform upper limb strength training, since the counterweight block is arranged on the counterweight frame 3, the trainee needs to expend more strength to pull the pull rod 14. Therefore, after a period of upper limb strength training, the trainee can adjust the increase or decrease of the counterweight block according to his own situation. When the trainee reduces the counterweight block in the counterweight frame 3, the push plate 15 can be pulled to move upward, so that the trainee can quickly take out the counterweight block from the counterweight frame 3. When the trainee takes out the last counterweight block in the counterweight frame 3, the trainee pulls the push plate 15 upward, and the push plate 15 is limited by two limit blocks 16, so that the trainee moves the push plate 15 upward, and it is not easy to move the push plate 15 and the counterweight block upward out of the counterweight frame 3, thereby avoiding injury to the trainee.

[0027] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are only illustrative and not restrictive.
