Description

Technical Field

[0001] This utility model relates to the field of fitness technology, and in particular to a stair climbing machine. Background Technology

[0002] Stair climbers are a highly efficient aerobic exercise that simulates climbing stairs. They have significant effects on burning fat, shaping the body, and improving cardiovascular function. However, attention should be paid to posture and joint protection. Home stair climbers are electric devices designed specifically for home environments to assist people with mobility impairments in overcoming stair obstacles and improving the convenience and safety of home life.

[0003] In existing technologies, traditional stair climbers rely on steel wire transmission, which can generate more noise and vibration at high speeds, impacting user experience. In contrast, belt drives, due to their softer material, effectively absorb some vibration and noise. However, steel wire drive components may wear out faster than belt drive components, requiring more frequent maintenance and replacement, increasing long-term operating costs. Steel wire drives also require high installation precision, ensuring proper wire rope tension and pulley alignment; otherwise, transmission efficiency may decrease or malfunctions may occur. Belt drives, on the other hand, are relatively easy to install and debug. In extreme cases, steel wire drives may cause more serious safety accidents, while the slippage characteristic of belt drives under overload can mitigate such risks to some extent. Therefore, an improved stair climber is needed to address these issues. Utility Model Content

[0004] In order to overcome the problems of the stair climbing machine using steel wire transmission, which affects user experience, increases long-term use costs, and causes transmission efficiency to decline or fail.

[0005] The technical solution of this utility model is as follows: a stair climber, including a support connecting base, a support base disposed on the support connecting base, a foot pedal disposed on the support base, a handle disposed on the support connecting base, a storage box disposed on the handle, a placement panel fixedly connected to the handle, an adjustment component disposed on the support connecting base, a connecting sliding seat slidably connected to the support connecting base, a rotating roller rotatably connected to the connecting sliding seat, a connecting fixed seat fixedly connected to the rotating roller, a fixed support seat fixedly connected to the support connecting base, a connecting limiting seat disposed on the fixed support seat, a first pulley rotatably connected inside the connecting limiting seat, a second pulley rotatably connected to the support connecting base, a transmission belt body pulsatingly connected to the second pulley and the first pulley, a data recording table disposed on the support connecting base, and the data recording table connected to the rotating end of the second pulley. The device is supported by the support base, and a tablet and mobile phone are placed on the placement panel. The foot pedal is provided for the user to step on.

[0006] Preferably, several rotating rollers are provided, and these rollers are uniformly connected inside the connecting sliding seat.

[0007] Preferably, the connecting slide seat has a groove at the corresponding position of the supporting connecting seat, and the connecting slide seat slides on the supporting connecting seat through the groove.

[0008] Preferably, a fixing bolt is provided on the connecting sliding seat, a rotating wheel is rotatably connected to the connecting sliding seat, an elastic rope is fixedly connected to the fixing bolt, and the elastic rope is drivenly connected to the rotating wheel.

[0009] Preferably, each of the two connecting sliding seats is equipped with a rotating wheel, and each of the two rotating wheels is connected to a driving elastic rope.

[0010] Preferably, the adjustment assembly includes a telescopic outer rod disposed on one side of the support connecting seat, a telescopic inner rod slidably connected inside the telescopic outer rod, an adjustment bolt disposed between the telescopic outer rod and the telescopic inner rod, an adjustment knob disposed between the telescopic outer rod and the support connecting seat, a rotating shaft fixedly connected inside the connecting sliding seat, an adjustment plate rotatably connected to the rotating shaft, and an adjustment screw hole opened on the connecting sliding seat.

[0011] Preferably, the telescopic inner rod is provided with several threaded holes, and the several threaded holes are evenly distributed on the telescopic inner rod.

[0012] Preferably, the connecting slide seat has a threaded hole at the corresponding position of the adjusting screw hole, and the threaded hole on the connecting slide seat corresponds to the through hole on the adjusting plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. Compared to stair climbers that use steel wire for transmission, this device uses a sliding connecting seat to drive a fixed connecting seat, which in turn pulls the supporting connecting seat between the first and second pulleys. Data is recorded using a data logging table. This method minimizes noise and vibration, and the wear rate of belt-driven components is slower than that of steel wire-driven components, reducing the need for frequent maintenance and replacement and lowering long-term operating costs. Steel wire drives are more complicated to install and prone to reduced transmission efficiency or malfunctions, potentially leading to more serious safety accidents. This belt-driven device is quieter, more reliable, and smoother to use than traditional steel wire rope drives, improving the user experience.

[0015] 2. The height is fixed by sliding the inner telescopic rod inside the outer telescopic rod, causing its threaded hole to push the adjusting bolt. The foot pedal angle is fixed by rotating the adjusting plate and aligning the adjusting screw hole with the threaded hole on the connecting sliding seat. Different users have different needs for climbing speed. By adjusting the transmission system, multiple speed modes can be achieved, from slow and smooth to fast and efficient, to meet different needs. In home use, users may prefer slow and smooth movement; while in public places, a faster speed may be needed to improve efficiency. The wire-driven stair climber needs to adjust the transmission tension according to the user's weight or load weight. For example, when carrying a heavier user, the wire rope pretension needs to be increased to avoid slippage; when carrying a lighter user, it can be appropriately loosened to reduce wear.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 - Figure 5This utility model provides an embodiment of a stair climber, including a support connecting seat 1, a support base 2 disposed on the support connecting seat 1, a foot pedal 3 disposed on the support base 2, a handle 4 disposed on the support connecting seat 1, a storage box 5 disposed on the handle 4, a placement panel 6 fixedly connected to the handle 4, an adjustment component disposed on the support connecting seat 1, a connecting sliding seat 801 slidably connected to the support connecting seat 1, a rotating roller 802 rotatably connected to the connecting sliding seat 801, a connecting fixing seat 803 fixedly connected to the rotating roller 802, a fixing support seat 811 fixedly connected to the support connecting seat 1, a connecting limiting seat 807 disposed on the fixing support seat 811, a first pulley 808 rotatably connected inside the connecting limiting seat 807, a second pulley 809 rotatably connected to the support connecting seat 1, and a transmission connection to the second pulley 809. The pulley 809 is connected to the transmission belt body 810 on the first pulley 808, and the data recording table 812 is set on the support connecting seat 1. The data recording table 812 is connected to the rotating end of the second pulley 809. The device is supported by the supporting base 2. The placement panel 6 is used to place tablets and mobile phones. The foot pedal 3 is provided for the user to step on. When the user steps on the foot pedal 3, the connecting sliding seat 801 slides on the support connecting seat 1 through the rotating roller 802. When the connecting sliding seat 801 slides on the support connecting seat 1, the connecting fixing seat 803 set on the connecting sliding seat 801 pulls the transmission belt body 810 to slide. The transmission belt body 810 is driven between the first pulley 808 and the second pulley 809 on the connecting limiting seat 807. The rotation of the second pulley 809 transmits data to the data recording table 812 for recording.

[0024] Please see Figure 2 - Figure 3In this embodiment, several rotating rollers 802 are provided, and these rollers 802 are evenly rotatably connected inside the connecting sliding seat 801. The presence of these rollers makes the connecting sliding seat 801 more stable when sliding on the supporting connecting seat 1. The connecting sliding seat 801 has a groove at a corresponding position on the supporting connecting seat 1, allowing it to slide on the supporting connecting seat 1. The groove on the connecting sliding seat 801 at the corresponding position on the supporting connecting seat 1 provides a guiding function during sliding. The connecting sliding seat 801 is equipped with fixing bolts 804 and connecting... A rotating wheel 805 is rotatably connected to the sliding seat 801. An elastic rope 806 is fixedly connected to the fixing bolt 804. The elastic rope 806 is driven to the rotating wheel 805. The sliding of the sliding seat 801 drives the fixing bolt 804 to pull the elastic rope 806 on the rotating wheel 805. The rotating wheel 805 pulls the other end of the sliding seat 801 to slide on the support connecting seat 1. Both sliding seats 801 are equipped with rotating wheels 805, and both rotating wheels 805 are driven to the elastic rope 806. The two rotating wheels 805 make the rotation of the wheel 805 smoother during transmission.

[0025] Please see Figure 4 - Figure 5 In this embodiment, the adjustment assembly includes a telescopic outer rod 901 disposed on one side of the support connecting seat 1, a telescopic inner rod 902 slidably connected inside the telescopic outer rod 901, an adjustment bolt 903 disposed between the telescopic outer rod 901 and the telescopic inner rod 902, an adjustment knob 904 disposed between the telescopic outer rod 901 and the support connecting seat 1, a rotating shaft 905 fixedly connected inside the connecting sliding seat 801, an adjustment plate 906 rotatably connected to the rotating shaft 905, and an adjustment screw hole 907 opened on the connecting sliding seat 801. By pulling the telescopic inner rod 902 to slide inside the telescopic outer rod 901, the adjustment assembly can be adjusted to the desired position. The height is fixed at a suitable position by adjusting bolt 903. Several threaded holes are provided on the telescopic inner rod 902, and these threaded holes are evenly distributed on the telescopic inner rod 902. The threaded holes make the telescopic inner rod 902 more flexible to adjust. The connecting sliding seat 801 has a threaded hole at the corresponding position of the adjusting screw hole 907, and the threaded hole on the connecting sliding seat 801 corresponds to the through hole on the adjusting plate 906. The threaded hole on the connecting sliding seat 801 at the corresponding position of the adjusting screw hole 907 makes it more flexible to adjust the foot pedal 3.

[0026] When the user steps on the foot pedal 3, the connecting sliding seat 801 slides on the supporting connecting seat 1 via the rotating roller 802. As the connecting sliding seat 801 slides on the supporting connecting seat 1, the connecting fixing seat 803 on the connecting sliding seat 801 pulls the transmission belt body 810 to slide. The transmission belt body 810 transmits power between the first pulley 808 and the second pulley 809 on the connecting limiting seat 807. The rotation of the second pulley 809 transmits data to the data recording table 812 for recording. When the foot pedal 3 is stepped on, the sliding of the connecting sliding seat 801 causes the fixing bolt 804 to pull the elastic rope 80. 6. The transmission is carried out on the rotating wheel 805. The rotating wheel 805 pulls the connecting sliding seat 801 at the other end to slide on the supporting connecting seat 1. When adjusting, the telescopic inner rod 902 is pulled to slide inside the telescopic outer rod 901 to a suitable position. The height is fixed by the set adjusting bolt 903. The supporting connecting seat 1 and the telescopic outer rod 901 are connected by the set adjusting knob 904. By rotating the adjusting plate 906 on the rotating shaft 905, the adjusting screw hole 907 on the adjusting plate 906 is aligned with the threaded hole on the connecting sliding seat 801. The tilt angle of the foot pedal 3 is fixed by the threaded bolt.

[0027] Through the above steps, the sliding of the connecting sliding seat 801 drives the connecting fixed seat 803 to pull the supporting connecting seat 1 through the first pulley 808 and the second pulley 809. The data is recorded by the set data recording table 812 to solve the problem that the stair climbing machine is affected by the transmission of steel wire, which affects the user experience, increases the long-term use cost, and reduces the transmission efficiency or causes failure.
