[0002] In the modern fitness field, strength training occupies a crucial position. It can not only effectively enhance muscle strength and improve the body's metabolic level, but also play a positive role in shaping a good physique and preventing sports injuries. In gyms, strength equipment such as fly machines and lat pulley combination machines provide users with diverse strength training methods by pulling with steel cables, which are favored by fitness enthusiasts and professional athletes.
[0003] The height of existing strength training equipment slides is fixed, making it impossible to flexibly adjust to different users' heights, body types, or training habits. For people with significant height differences, fixed-height slides can cause unnatural training postures, reduce training effectiveness, and may even lead to sports injuries due to improper posture. In addition, different types of strength training, such as seated lat pulldowns and overhead lat pulldowns, require slides to be at different heights to adapt to the movement requirements, and fixed-height slides cannot meet this diverse need. The few that do have height adjustment usually require disassembly and reassembly using bolts, making it difficult for users to adjust them conveniently themselves. Therefore, improvements are needed to address these issues. Utility Model Content

This structure, through the cooperation of the mounting bracket 1 and the counterweight 5, facilitates the adjustment of the counterweight according to training needs, improves the adaptability of training, and enables diversified strength training. Multiple locking holes are equidistantly opened on both sides of the guide column 4. A sliding sleeve 10 is clamped to the guide post 4 at the locking hole. The inner wall of the sliding sleeve 10 has symmetrically formed limit grooves 14 on both sides. A limit block 11 corresponding to the locking hole is provided in each limit groove 14. A spring 12 is fixedly connected to one side of each limit block 11. The sliding sleeve 10 is made of high-strength aluminum alloy, characterized by its light weight and high strength. Through the cooperation between the guide post 4 and the sliding sleeve 10, the sliding sleeve 10 can slide up and down along the guide post 4, improving the flexibility of the slide height adjustment. This allows for flexible adjustment of the slide height according to the height, body type, or training habits of different users. The spring 12... One end of spring 12 is fixed to the inner wall of the locking hole. A connecting rod is sleeved inside spring 12. One end of the connecting rod is fixed to the limiting block 11. The other end of the connecting rod passes through the outer wall of the sliding sleeve 10 and is fixed to a pull ring 13. Spring 12 is model SWP-B and is made of high-quality spring steel with an elastic modulus of 206GPa, which can provide stable elastic force. Through the cooperation of the limiting block 11, spring 12 and pull ring 13, the position of the sliding sleeve 10 can be quickly locked, which improves the stability and convenience of height adjustment, and thus enables the function of adjusting the height of the carriage without removing the bolts.
[0020] In this invention, a pulley group 9 is fixedly connected to one side of the outer wall of the sliding sleeve 10. A steel wire rope 2 is wound around the fixed pulley. One end of the steel wire rope 2 passes sequentially through the lower end of the movable pulley 8, the upper end of the lifting pulley and the guide pulley, and the pulley group 9, and is fixedly connected to a pull arm. The steel wire rope 2 is a 6×19+FC-12 type, made of high-strength carbon steel, with a breaking tensile strength of 80kN, and has good wear resistance and fatigue resistance. Through the cooperation of the pulley group 9 and the steel wire rope 2, it is easy to realize multi-directional tension transmission, improve the diversity and comfort of training, and thus realize the function of different training movements. A locking wheel 6 is provided on the rope between the lifting pulley and the movable pulley 8 of the steel wire rope 2. The locking wheel 6 has a built-in shaft, and the steel wire rope 2 is wound on the shaft. A ratchet 15 is coaxially fixed to one end of the shaft. The inner wall of the locking wheel 6 rotates. The device includes a pawl 17 for locking the ratchet 15; the locking wheel 6 is made of cast steel with a surface hardened to a hardness of HRC45-50; the combination of the locking wheel 6, ratchet 15, and pawl 17 facilitates reliable locking of the wire rope 2, improving the reliability of the wire rope locking and enabling stable fixation of the wire rope 2 during training; a knob 18 is rotatably mounted on one side of the outer wall of the locking wheel 6, which is coaxially fixed to the pawl 17, and a hand crank 16 is coaxially fixed to one end of the rotating shaft and mounted on one side of the outer wall of the locking wheel 6; the knob 18 is made of non-slip rubber with a textured surface to increase friction; the combination of the knob 18 and the hand crank 16 facilitates manual control of locking and releasing the wire rope 2, improving the convenience and safety of operation, and enabling quick adjustment of the wire rope 2 length.
[0021] Working principle: When using this utility model, the user first pulls the pull ring 13, causing the spring 12 to be compressed. The limiting block 11 disengages from the locking hole of the guide post 4, allowing the sliding sleeve 10 to slide up and down along the guide post 4 to the appropriate position. Releasing the pull ring 13 causes the spring 12 to return to its original shape, pushing the limiting block 11 back into the corresponding locking hole, thus fixing the height of the slide frame. During training, the user pulls the arm, and the wire rope 2 is driven between the fixed pulley, the movable pulley 8, the lifting pulley, the guide pulley, and the pulley block 9. When it is necessary to fix the position of the wire rope 2, the knob is turned. 18 drives the pawl 17 to rotate, and the pawl 17 locks the ratchet 15, preventing the shaft inside the locking wheel 6 from rotating, thereby fixing the steel wire rope 2 wound on the shaft and locking it to ensure stable training tension. To adjust the tension, the counterweight 5 on the mounting frame 1 can be added or removed. The counterweight 5 is connected to the r-shaped bracket 3 through a connecting rope, and the tension on the steel wire rope 2 is changed under the action of the movable pulley 8. In addition, turning the hand crank 16 can drive the shaft to rotate, and the winding length of the steel wire rope 2 can be manually adjusted to meet different training needs. At this point, the device is in use.
