[0002] In the fields of fitness training and rehabilitation medicine, strength training equipment is an important tool to help users increase muscle strength and improve physical function. Traditional fitness equipment often features fixed armrests or complex knob and bolt adjustment mechanisms, requiring users to spend considerable time and effort adjusting their positions before training, sometimes even needing additional tools. During training, adjusting the armrest extension length to accommodate different movements is extremely inconvenient, significantly impacting training fluidity and motivation. Fixed armrest designs cannot accommodate the individual needs of trainees of varying heights and body types; armrests that are too far or too close can cause postural distortions during movements, potentially leading to muscle strain and joint pain with prolonged use. Furthermore, the lack of flexible armrest adjustment fails to provide effective support, causing fatigue during extended training sessions and severely reducing comfort and sustainability. Therefore, improvements are needed to address these issues. Utility Model Content

[0014] Example: See Figure 1-4This utility model discloses a strength training device with an adjustable slide, comprising a base frame 1, a seat 3 fixedly attached to one end of the top surface of the base frame 1, a support frame 5 fixedly attached to the middle of the top surface of the base frame 1, two sets of fixed pulleys 6 symmetrically arranged at both ends of the top surface of the support frame 5, and a column 13 fixedly attached to the base frame 1 on one side of the support frame 5. Multiple anti-slip pads 2 are provided on the bottom surfaces of both the base frame 1 and the column 13. The base frame 1, seat 3, and support frame 5 constitute a stable main structure, providing a support base for training. The fixed pulleys 6 are made of aluminum alloy and have an anodized surface. Combined with the pull rope 8, they allow for changes in the direction of force, are wear-resistant and smooth, and facilitate diverse training movements. The column 13 is used to install counterweights 15 to adjust the training resistance. The anti-slip pads 2 are made of high-friction rubber, increasing friction with the ground and effectively preventing the device from sliding during training, thus improving the safety and stability of the training. A telescopic column 9 is fixedly attached to the opposite surface of the support frame 5 and the seat 3. A seat armrest 4 is fixedly attached to the telescopic end of the telescopic column 9, and a spring is provided at one end of the telescopic end of the telescopic column 9. The spring-loaded locking blocks 10 and the fixed cylinder of the telescopic column 9 are provided with multiple corresponding locking holes at equal intervals. The telescopic column 9 adopts a hydraulic telescopic structure of model YT-003. By pressing the spring-loaded locking blocks 10, the limit can be released, allowing for convenient and quick adjustment of the extension length of the seat armrest 4 to meet the needs of trainees of different body types. The cooperation between the spring-loaded locking blocks 10 and the locking holes ensures that the seat armrest 4 can be firmly fixed after adjustment, providing reliable support for the trainee. The spring-loaded locking blocks 10 are made of high-strength stainless steel, which is corrosion-resistant and not easily deformed. The shape improves the comfort and adaptability of training; the column 13 is hollow inside and has first through slots on both sides, and multiple counterweights 15 are installed inside the column 13; the hollow structure and first through slot design of the column 13 facilitate the installation and removal of the counterweights 15; the counterweights 15 are made of high-density, weight-stable cast iron material, and each standard weight is 5kg. Trainees can increase or decrease the number of counterweights 15 according to their own needs, flexibly adjust the training resistance, realize personalized training intensity adjustment, and improve the pertinence and effectiveness of training.
[0015] In this utility model, the support frame 5 is T-shaped. A mounting column is fixedly connected to one side of the inner top surface of the support frame 5. The bottom end of the mounting column is fixedly connected to the base frame 1. A sliding groove is formed on the upper part of one side of the mounting column. Multiple grooves 14 are equidistantly formed on both sides of the inner wall of the sliding groove. A slider 11 is slidably mounted on the sliding groove. A third guide wheel is fixedly connected to the slider 11. An installation platform is fixedly connected to the outer wall of the mounting column at the lower end of the sliding groove. The T-shaped support frame 5 enhances the stability of the overall structure. The cooperation of the mounting column, the sliding groove, and the slider 11 allows the slider 11 to slide up and down along the sliding groove, facilitating the adjustment of the height of the third guide wheel. The grooves 14 provide multiple selectable positions for the positioning of the slider 11. The contact part of block 11 is made of wear-resistant engineering plastic, reducing friction and improving the flexibility and convenience of slide adjustment, which can adapt to the height and training movement needs of different trainees; two first springs 17 are provided inside the slider 11, and a push plate 16 is fixedly connected to one end of the first spring 17. A limiting block 18 corresponding to the groove 14 is fixedly connected to one side of the push plate 16; the first spring 17 is made of 65Mn spring steel, which has good elasticity and fatigue resistance, and can ensure long-term use without failure; when the push plate 16 is pressed, the first spring 17 is compressed, which drives the limiting block 18 to disengage from the groove 14, allowing the slider 11 to slide freely; after the push plate 16 is released .... Spring 17 resets and pushes limit block 18 into groove 14, achieving rapid positioning and stable fixation of slider 11, simplifying the slide adjustment process and improving adjustment efficiency; a first guide wheel is installed at the bottom of the mounting column, and a combined wire group connected to counterweight 15 extends from one side of the bottom of column 13. The wire group passes through the first guide wheel and is installed with a movable pulley 12, which is figure-eight shaped. The combined wire group is divided into three groups of pull ropes 8 by the movable pulley 12. One group of the three groups of pull ropes 8 passes through the movable pulley 12 and is fixed to the top surface of the base frame 1. Another group of the three groups of pull ropes 8 passes through the movable pulley 12 and the third guide wheel in sequence and is fixed to the top surface of the mounting platform. One of the three sets of pull ropes 8 passes sequentially through the movable pulley 12 and the fixed pulley 6 and is fixedly connected to a handle 7, which is located at the upper end of the seat 3. The first guide wheel, the movable pulley 12, and the fixed pulley 6 are all made of aluminum alloy with anodized surfaces, making them wear-resistant and with low rotational resistance. The unique layout of the figure-eight movable pulley 12 and the three sets of pull ropes 8 enables multi-directional transmission and amplification of force. When the trainee pulls the handle 7, they can perform training movements in various directions and angles, greatly enriching the training methods. The pull ropes 8 are made of high-strength, wear-resistant nylon rope with internal steel wire reinforcement to enhance load-bearing capacity, ensuring the stability and reliability of force transmission and improving the diversity and effectiveness of training.
[0016] Working Principle: When using this utility model, the user first sits on the seat 3, presses the spring clip 10 at the telescopic end of the telescopic column 9 to disengage it from the fixed cylinder hole, pulls the seat armrest 4 to adjust the extension length, and after adjustment, the spring clip 10 re-engages into the hole under the action of elasticity; during strength training, the user holds the handle 7 and pulls to move the three sets of ropes 8. The figure-eight shaped movable pulley 12 realizes the transmission of force and change of direction. One set of ropes 8 is fixed to the top surface of the base frame 1 to stabilize the movable pulley 12, another set passes through the movable pulley 12 and the third guide wheel in sequence and is fixed to the top surface of the mounting platform, and the third set passes through the movable pulley 12 and the fixed pulley 6 in sequence. Connected to handle 7, it enables multi-directional force transmission and diverse training movements. When adjusting the training resistance, pulling the combined line group changes the number of counterweights 15 inside the column 13. The combined line group converts the gravity of the counterweights 15 into training resistance through the first guide wheel and the movable pulley 12. When adjusting the position of the slider 11 (i.e., the slide), pressing the push plate 16 causes the push plate 16 to overcome the elasticity of the first spring 17 and drive the limiting block 18 to move into the slider 11 and disengage from the groove 14. The slider 11 slides along the groove and, after reaching the desired position, the push plate 16 is released. The first spring 17 pushes the push plate 16 back to its original position, causing the limiting block 18 to re-engage into the groove 14 and fix the slider 11. The height of the third guide wheel is changed to adapt to the needs of different trainees. Thus, the device is used successfully.
