[0002] The hanging piece type strength training device is a professional device for targeted strength training of each muscle group of the whole body by adjusting resistance through adding or reducing weight pieces. The core use is to meet the needs of muscle gain, shaping, and strength improvement, and to provide precise and controllable resistance. The weight of the weight piece is clear, and the load can be gradually increased according to the level of the user. It is suitable for users at different stages from beginners to advanced users. By replacing different training accessories (such as handles and ropes), the whole body muscles such as back, chest, shoulders, arms, legs, and core can be exercised. It is one of the core devices in a gym, and can complete various classic strength training movements such as high-low pull, sitting rowing, chest push, and leg lifting.

The device includes a main support, a lubricating mechanism, and a high pull mechanism. The device allows the user to place the barbell pieces on the connecting column according to actual needs, and can perform low pull training through the second handle and support frame, and high pull fitness training by sitting on the seat cushion. By pulling the first handle, the connecting rope and the pulley are used to drive the sliding sleeve to rise on the support slide column. When the sliding sleeve descends, the sliding sleeve extrudes the oil cake, and the lubricating oil in the oil cake is extruded and then sprayed through the micro-hole nozzle. A small amount of lubricating oil is sprayed on the support slide column, and the sliding sleeve rises upwards to lubricate the support slide column, thereby facilitating the addition of lubricating oil for the user to perform fitness training, thereby improving the smoothness of the training device.

The massage mode can be selected according to the needs, such as point pressure massage or sliding massage.

[0034] Working Principle: First, when using the hanging plate strength training device to train upper limb strength, the training intensity can be adjusted through the counterweight mechanism. After the person sits on the seat 12, limb training can be performed with the help of the rope assembly. During training, to prevent the trainee from arching or leaning back too much during the pull-ups and downs, which would cause the waist to exert force, the second motor 30 is controlled to drive the first reducer 29 to move. When the first reducer 29 moves, it drives the support shaft 26 to rotate. When the support shaft 26 rotates, it drives the support block 25 to rotate. The support block 25 rotates inside the support frame 16, causing the bar frame 31 to move to a predetermined angle, which will place the first electromagnet 27 inside the support frame 16. The first electromagnet 27 is in contact with the inner wall of the support frame 16. Controlling the first electromagnet 27 to work generates a strong magnet, which then... The support block 25 and the strip frame 31 are temporarily fixedly connected to the support frame 16, thereby positioning the support block 25 and the strip frame 31. When the support block 25 rotates, it drives the strip groove 22 to move, aligning the locking block 24 with the locking groove 21. Then, the first electric push rod 23 is controlled to move the locking block 24. After the locking block 24 moves into the locking groove 21, the support block 25 is temporarily limited to the slider 17, positioning the support block 25 and the strip frame 31. The first motor 20 is controlled to rotate the threaded rod 18, which causes the slider 17 to move. When the slider 17 moves, it drives the support frame 16 to move. With the help of the guide rod 76, the support frame 16 is guided to move smoothly. The positions of the bar frame 31 and the curved rubber plate 32 can be adjusted. After the curved rubber plate 32 moves to the side of the trainee's spine, it will limit the trainee's back. When the trainee arches or leans back too much during lat pulldown training, the bar frame 31, through the curved rubber plate 32, will block the trainee's spine, thereby correcting the trainee's posture and effectively preventing lumbar spine overload and injury. At the same time, it ensures that the training effect does not deviate significantly from the target. Before and after training, the trainee controls the extension and retraction of the second electric push rod 36, which will drive the corresponding bar plate 34 to move. When the bar plate 34 moves, it will drive the limiting ring 39 to move. Through the cooperation of the limiting shaft 38 and the limiting ring 39, the bar plate 34 is guided, so that the bar plate 34 moves. 4. Smooth movement: The operation of the dual-output shaft motor 64 drives the second reducer 65, which in turn drives the crankshaft 66. The crankshaft 66, through the interaction of the push plate 67 and the driven plate 68, drives the drive block 69. The drive block 69 then drives the second electromagnet 71. After adjusting the position of the strip plate 34, the square hole 47 at the bottom of the strip plate 34 aligns with the limiting groove 70. The second electromagnet 71, after entering the groove 40 through the square hole 47, generates a strong magnet, which limits the sliding plate 41. The repeated movement of the second electromagnet 71 causes the sliding plate 41 to move up and down repeatedly. The movement of the drive block 69 drives the drive rod 72 and the third electromagnet 74.The drive rod 72 and the third electromagnet 74 are located directly below the connecting cylinder 60. The third electromagnet 74 generates a strong magnet, which drives the connecting rod 58 to move synchronously through the connecting cylinder 60. When the connecting rod 58 moves up and down repeatedly, it drives the compression block 59 to move. When the compression block 59 moves, it compresses the air between the compression block 59 and the plate 56. The sealing ring 57 is used to seal the gap between the connecting rod 58 and the plate 56. The compressed air enters the interior of the connector 61 and flows into the corresponding cylinder 48 through the telescopic hose 54. When the connecting rod 58 drives the compression block 59 to reset, the compressed air flows back into the space between the compression block 59 and the plate 56. After the massage head 49 is positioned on the massage side, the compressed air enters the cylinder 48 through the telescopic hose 54 and pushes the piston block 53 to move. The movement of the piston block 53 drives the massage head 49 to move synchronously through the sliding rod 51. When the massage head 49 moves and contacts the muscles on one side of the spine, it applies pressure massage. After the gas returns, spring 52 resets, pushing piston block 53 back to its original position, which in turn drives massage head 49 back to its original position. This process repeats, allowing for massage and relaxation of the muscles on one side of the spine. The up-and-down movement of sliding plate 41 expands the massage area, facilitating muscle relaxation and effectively preventing muscle soreness. It can massage the muscles beside the spine in the back. Gentle pressure on these muscles before training can have a relaxing effect, its core function being to awaken relaxation and quickly relieve surface muscle tension, placing the muscles on both sides of the spine in a state that is neither too tight nor too loose. This lays the foundation for power generation and a neutral spinal position during training. Massaging after training promotes local blood circulation, relieves post-training muscle tension, reduces delayed onset muscle soreness, and prevents excessive muscle tension from straining the spine, ensuring the effectiveness of the plate-type strength training device.
