[0002] With the growing popularity of the national fitness concept, the fitness industry has experienced explosive growth, and the market demand for fitness equipment has also risen sharply. More and more people are choosing to use fitness equipment for daily exercise in order to pursue a healthier body and ideal physique. However, while fitness activities are becoming more widespread, sports injuries are becoming increasingly serious, becoming an important factor that plagues fitness enthusiasts and restricts the healthy development of the industry.

[0003] Traditional fitness equipment is often designed and functionally focused on meeting basic exercise needs, and generally lacks a comprehensive and effective injury prevention mechanism. When adjusting weights or performing exercises such as lifting, users rely entirely on their own experience and subjective judgment to control exercise intensity and posture. Due to the lack of real-time and accurate monitoring and guidance, even slight carelessness can lead to serious damage to joints and muscle tissues such as the waist, shoulders, and elbows due to incorrect force exertion. Moreover, such damage is often irreversible and has a long-term negative impact on the user's health. Therefore, it is necessary to address the above problems. Utility Model Content

[0008] Preferably, the bottom end of the seat is inserted into the guide rod, and the main frame is provided with a sliding groove to facilitate the movement of the seat.

[0009] Preferably, a second motor is installed on both sides of the main frame, and a worm gear is installed at the output end of the second motor through a coupling. A worm wheel is engaged with the upper end of the worm gear, and an auxiliary shaft is fixedly connected to one side of the worm wheel. The foot pedal is installed on the auxiliary shaft.

[0010] Preferably, the stretching mechanism includes a resistance device installed in the take-up box, an auxiliary roller and a reduction roller installed at the rear end of the resistance device, a first gear and a second gear respectively installed on the auxiliary roller and the reduction roller, the first gear and the second gear meshing and driving each other, and the resistance device consists of an electromagnetic assembly and a flywheel.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example: See Figure 1-7This utility model discloses an intelligent anti-injury fitness equipment, comprising a main frame 1 and a cable take-up box 2 installed at the front end of the main frame 1, which facilitates the installation of a resistance device 15. A buffer mechanism is installed on the main frame 1, and a tensioning mechanism is installed inside the cable take-up box 2. Safety railings 3 are installed on both sides of the main frame 1 to prevent users from falling off. A seat 10 is installed on the main frame 1, and two foot pedals 4 are installed at the rear end of the cable take-up box 2 to facilitate lower limb strength training. The foot pedals 4 are located on both sides of the main frame 1. The buffer mechanism includes a first motor 5 installed at the rear end of the main frame 1 and a guide rod 7 rotatably installed inside the main frame 1. The first motor 5 facilitates the rotation of a bidirectional lead screw 6, and the guide rod 7 facilitates the movement of the seat 10. The guide rod 7 is located above the first motor 5, and the output end of the first motor 5 is connected via a coupling. A double-acting lead screw 6 is provided, which facilitates the movement of the buffer plates 8 at both ends. Two buffer plates 8 are threaded to both ends of the double-acting lead screw 6, which, in conjunction with buffer springs 9, prevent injury to the exerciser. Multiple buffer springs 9 are installed between the two buffer plates 8. The bottom of the seat 10 is inserted into the guide rod 7, and the main frame 1 has a sliding groove for the seat 10 to move. Second motors 11 are installed on both sides of the main frame 1, which drive the worm gear 12 to rotate. The output end of the second motor 11 is connected to the worm gear 12 via a coupling, which drives the worm wheel 13 to rotate. The upper end of the worm gear 12 is engaged with the worm wheel 13, which drives the auxiliary shaft 14 to rotate. The auxiliary shaft 14 is fixed to one side of the worm wheel 13, which allows the foot pedal 4 to be tilted according to exercise needs. The foot pedal 4 is mounted on the auxiliary shaft 14.

[0025] In this invention, the tensioning mechanism includes a resistance device 15 installed inside the take-up box 2, an auxiliary roller 16 and a reduction roller 17 installed at the rear end of the resistance device 15. The resistance device 15 facilitates the inward pulling of the traction rope; the auxiliary roller 16 facilitates the winding of the traction rope and the installation of the first gear; and the reduction roller 17 facilitates the installation of the second gear. The first gear and the second gear are respectively installed on the auxiliary roller 16 and the reduction roller 17, and the first gear meshes with the second gear for transmission. The resistance device 15 consists of an electromagnetic assembly and a flywheel. A third gear is installed inside the take-up box 2. The motor 18 facilitates the rotation of the one-way lead screw via the third motor 18; the output shaft of the third motor 18 is equipped with a one-way lead screw via a coupling, and a reduction disc 19 is threaded onto the one-way lead screw. The reduction disc 19 facilitates the generation of friction with the second gear to reduce the rotation speed of the reduction roller 17; one end of the reduction disc 19 abuts against one side of the second gear; a traction rope is wound inside the resistance device 15; the other end of the traction rope is wound around the auxiliary roller 16, and a pull rod 20 is installed at the other end of the traction rope, which facilitates pulling the traction rope to exercise the upper limbs.

[0026] Working principle: When using this utility model, first, the device is powered on. Then, the exerciser sits on the seat 10, turns on the second motor 11, drives the worm gear 13 to rotate through the worm 12, and the worm gear 13 drives the auxiliary shaft 14 to rotate, thereby adjusting the tilt angle of the foot pedal 4. Then, the first motor 5 is turned on, and the first motor 5 drives the bidirectional lead screw 6 to move the buffer plates 8 on both sides to the appropriate position. Then, the user holds the pull rod 20, exerts force with their legs, pushes the seat 10 backward, and pulls the traction rope out of the resistance device 15. Then, the resistance device 15 will pull the traction rope back to its original position. At this time, the third motor 18 is started, drives the reducer 19 to move through the unidirectional lead screw, and abuts against one side of the second gear. At this time, due to friction, the rotation speed of the reducer roller 17 decreases, and the rotation speed of the resistance device 15 also decreases, thereby slowing down the speed of the traction rope retraction. When the traction rope is retracted, the seat 10 will abut against the buffer plate 8 to avoid direct impact and injury to the exerciser.
