[0002] Climbing stairs is an aerobic exercise that can strengthen lower limb muscles, improve cardiopulmonary function, and increase the load, requiring muscles to exert more force to overcome gravity, thus providing a more thorough workout.
[0003] For example, Chinese patent CN216571425U discloses an upper limb weight-bearing training staircase machine, including a staircase training base, on which a staircase capable of cyclical movement is installed, allowing users to simulate the action of climbing stairs for exercise; an upper limb training support is installed on the upper part of the staircase training base, and a weight-bearing training frame is rotatably installed on the upper limb training support. The weight-bearing training frame can rotate relative to the user, and a barbell mounting rod is provided on the weight-bearing training frame, with a corresponding number of barbells installed according to specific usage needs.
[0004] While the aforementioned patents improve training effectiveness and enjoyment, they still have some shortcomings that need improvement. The existing weight-bearing stair climbers only have their bottom support pillars in contact with the ground, making them unstable. This single support method makes the machine appear unstable when placed, and it is prone to shaking or shifting during use, which may affect the safety of the trainee and the stability of the training effect.

[0021] Example
[0022] refer to Figures 1 to 5 This embodiment describes a highly stable load-bearing staircase, comprising a staircase body 1, a training ladder 2 on one side of the staircase body 1, a display screen 3 fixedly connected to the side of the staircase body 1 away from the conveyor belt, and fixed plates 4 fixedly connected to both sides of the staircase body 1. The fixed plates 4 have grooves 41 inside, and rubber wheels 5 are provided on one side of the grooves 41. Rubber strips 6 are fixedly connected to the rubber wheels 5. A power assembly 9 is provided on one side of the fixed plates 4, and a transmission mechanism 10 is provided on one side of the grooves 41. A positioning rail 7 is fixedly connected to the bottom of the staircase body 1, and a fixing block 8 is inserted into the positioning rail 7. Through this improved design, shaking or displacement of the machine during use is effectively prevented. When the machine is stable, the trainee can focus more on the training itself without worrying about the training rhythm being interrupted by machine shaking, providing a smoother and more stable training experience, thereby improving the overall satisfaction of the trainee and ensuring the stability and effectiveness of the training effect.
[0023] refer to Figure 3The power assembly 9 includes a motor 91, which is fixedly connected to the fixed plate 4 near the groove 41. A worm gear 92 is fixedly connected to the output end of the motor 91. The worm gear 92 is rotatably connected inside the groove 41. A worm wheel 93 is meshed with one side of the worm gear 92. A shaft 94 is fixedly connected to one side of the worm wheel 93 and rotatably connected inside the groove 41. One side of the transmission mechanism 10 is fixedly connected to the shaft 94. By setting up the power assembly 9, the motor 91 drives the worm gear 92 to rotate, which in turn drives the worm wheel 93 to rotate. The worm wheel 93 then drives the shaft 94 to rotate, thereby causing the shaft 94 to drive the transmission mechanism 10 to work, which in turn drives the rubber wheel 5 to work.
[0024] refer to Figure 4 The transmission mechanism 10 includes a fixed rod 101, which is fixedly connected to the shaft 94 on one side of the worm gear 93. A slider 102 is slidably connected inside the fixed rod 101. A movable rod 103 is fixedly connected to one end of the slider 102 away from the fixed rod 101. A fixing component 104 is provided on the fixed rod 101. The rubber wheel 5 is rotatably connected to the inside of the movable rod 103. By installing the fixed rod 101 on the shaft 94, the slider 102 slides inside the fixed rod 101. The slider 102 is connected to the movable rod 103. Pulling the movable rod 103 causes the slider 102 to slide on the fixed rod 101, thereby extending the rubber wheel 5 and making it contact the ground.
[0025] refer to Figure 5The fixing component 104 includes positioning holes 1041, which are formed inside the slider 102, and two such holes are provided. A positioning rod 1042 is inserted into one side of the fixing rod 101, and one side of the positioning rod 1042 is movably connected to the positioning hole 1041. A slot 11 is formed on one side of the positioning rod 1042. A mounting block 1044 is fixedly connected to one end of the fixing rod 101. A limit rod 1043 is slidably connected inside the mounting block 1044. One side of the limit rod 1043 passes through the slot 11 and is inserted into the positioning rod 1042. A spring 1046 is fixedly connected inside the mounting block 1044, and a push plate is fixedly connected to one end of the spring 1046. 1045, the end of the push plate 1045 away from the spring 1046 is fixedly connected to one end of the limiting rod 1043; by setting the fixing component 104, the push plate 1045 is pushed to move, and the push plate 1045 drives the limiting rod 1043 to move. At this time, the spring 1046 connected to the push plate 1045 deforms. When the positioning rod 1042 is inserted into the positioning hole 1041 to fix the slider 102 and the fixing rod 101, that is, when the moving rod 103 and the fixing rod 101 are fixed, the push plate 1045 is released. At this time, the limiting rod 1043 resets and passes through the slot 11 to insert into the inside of one side of the positioning rod 1042, so as to keep the moving rod 103 and the fixing rod 101 fixed, and prevent the two from loosening and causing the position of the rubber wheel 5 to change.
[0026] refer to Figure 1 The staircase body 1 is equipped with handrails 12 on both sides, and the handrails 12 are located above the conveyor belt; by setting the handrails 12, a fulcrum is provided to facilitate the operation of the fitness personnel.
[0027] Operating principle and advantages: A positioning rail 7 is installed at the bottom of the stair body 1. Multiple fixing blocks 8 are fixed in the installation area of the gym. The positioning rail 7 is slidably installed on the fixing blocks 8, which can prevent the stair body 1 from moving back and forth. Then, the motor 91 drives the worm gear 92 to rotate, the worm gear 92 drives the worm wheel 93 to rotate, the worm wheel 93 drives the shaft 94 to rotate, the shaft 94 drives the fixed rod 101 to rotate, which in turn drives the moving rod 103 to rotate. This causes the moving rod 103 to drive the rubber wheel 5 to unfold and form a certain angle with the stair body 1. Then, the push plate 1045 is pushed, the push plate 1045 drives the limit rod 1043 to move, and then the positioning rod 1042 is inserted into the positioning hole 1041, so that the slider 10 2. Keep the fixed rod 101 fixed, then release the push plate 1045. At this time, the spring 1046 will no longer be under force and will recover its deformation, causing the push plate 1045 to drive the limit rod 1043 through the slot 11 and insert it into the positioning rod 1042 to fix the positioning rod 1042. This will keep the moving rod 103 and the fixed rod 101 fixed, preventing them from becoming loose and causing the rubber wheel 5 to shift and affect the support. The rubber strip 6 of the rubber wheel 5 contacts the ground, increasing the frictional resistance and preventing the machine from shaking or shifting during use. When the machine is stable, the trainee can focus more on the training itself without worrying about the training rhythm being interrupted by the machine shaking, which can bring the trainee a smoother and more stable training experience.
