[0004] Although the aforementioned utility model features a control handle for easy gripping by the user, with the handle electrically connected to the control panel and multiple buttons on it that control the drive mechanism via the control panel, the armrest is fixed. Users of different heights and with varying usage habits have different needs for armrest height. A fixed armrest height will not accommodate all users' heights and body types, leading to discomfort or fatigue during use. This discomfort may be exacerbated, especially during prolonged use. Utility Model Content

[0005] In response to the problems mentioned in the background art, the purpose of this utility model is to provide an easily adjustable load-bearing stair handrail to solve the problem that users of different heights and usage habits have different needs for handrail height. If the handrail height is fixed, it will not be able to adapt to the height and body shape of all users, resulting in discomfort or fatigue during use, especially when used for a long time, this discomfort may be aggravated.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An easily adjustable load-bearing stair handrail includes a load-bearing stair body, a base installed at the bottom of the load-bearing stair body, shock-absorbing components symmetrically installed between the bottom of the base and the load-bearing stair body, fixed frames symmetrically fixedly connected to both ends of the load-bearing stair body, a fixed column fixedly connected to the top of the load-bearing stair body, a receiving cavity opened inside the load-bearing stair body, a cylinder installed at the bottom of the receiving cavity, a mounting column at the top of the fixed column, and a moving groove opened at the top of both the fixed column and the bottom of the mounting column, the moving groove communicating with the inside of the receiving cavity, a pushing column fixedly connected to the telescopic end of the cylinder, the other end of the pushing column fixedly connected to one end of the moving groove inside the mounting column, the pushing column and the moving groove being slidably connected, a handrail frame slidably connected to the top of the fixed frame, a control panel installed at the top of the mounting column, a cup holder and a mobile phone holder movably connected to one end of the handrail frame, and fixed components installed near the end of the cup holder and mobile phone holder near the handrail frame, which can be adjusted according to the user's height and operating habits, thus providing a more comfortable user experience and helping to reduce fatigue caused by long-term operation.

[0008] As a preferred technical solution, positioning blocks are symmetrically fixedly connected at both ends inside the moving groove, and positioning grooves are symmetrically opened at both ends of the pushing column. The positioning blocks and positioning grooves are slidably connected. The cooperative design of the positioning blocks and positioning grooves enables the handrail to maintain smooth movement during the lifting process.

[0009] As a preferred technical solution, the shock absorption component includes an internal hole, a shock absorption seat, a first limiting post, an internal hole, a second limiting post, and a first shock absorption spring. The bottom of the load-bearing staircase body has symmetrically symmetrically opened mounting grooves. Shock absorption seats are symmetrically fixedly connected to the upper end of the mounting groove and the upper end of the base. The upper end of the shock absorption seat on the upper end of the base is fixedly connected to the first limiting post. An internal hole is opened at the upper end of the first limiting post. The bottom end of the internal hole is fixedly connected to the first shock absorption spring. The other end of the first shock absorption spring is fixedly connected to the second limiting post. The second limiting post is slidably connected to the internal hole. The other end of the second limiting post is fixedly connected to the shock absorption seat inside the mounting groove. Second shock absorption springs are sleeved on the outer sides of both the first and second limiting posts. The two ends of the second shock absorption springs are fixedly connected to the opposite ends of the shock absorption seat, respectively. This effectively absorbs and disperses the vibration and impact generated during the operation of the stair climber, thereby ensuring stable operation of the machine on the stairs. It not only reduces machine shaking but also avoids operational errors or safety risks caused by vibration.

[0010] As a preferred technical solution, the fixing component includes a cavity, a return spring, a moving plate, and a locking block. A mounting bracket is fixedly connected to one end of both the cup holder and the phone holder. A connecting block is fixedly connected to the end of the mounting bracket near the armrest. A cavity is formed inside the connecting block, and a return spring is fixedly connected to one end of the cavity. A moving plate is fixedly connected to the other end of the return spring, and the moving plate is slidably connected to the cavity. A locking block is fixedly connected to the end of the moving plate away from the return spring, and the other end of the locking block extends out of the connecting block. A connecting groove is formed at one end of the armrest, and the connecting groove and the connecting block are plugged in. A locking groove is formed at one end of the connecting groove, and the locking groove and the locking block are snapped together. An unlocking block is slidably connected inside the locking groove, and the end of the unlocking block away from the locking block extends out of the armrest. Limiting blocks are symmetrically fixedly connected to both ends of the unlocking block. Limiting grooves are symmetrically formed inside the locking groove, and the limiting grooves and the limiting blocks are slidably connected. This facilitates the installation and removal of the phone holder or cup holder, making it easier to carry and use personal items, thereby improving the user experience.

[0011] In summary, the present invention has the following main advantages:

[0012] First, in this utility model, based on the user's height and body type, the cylinder is activated via the control panel, which controls the cylinder to push the push column upward. During the upward movement of the push column, it simultaneously slides inside the moving groove, causing the positioning groove to slide outside the positioning block. The push column pushes the mounting column upward, and during the upward movement of the mounting column, it simultaneously causes the handrail frame to rise, thus completing the height adjustment of the handrail frame. This can be adjusted according to the user's height and operating habits, thereby providing a more comfortable user experience and helping to reduce fatigue caused by prolonged operation.

[0013] Secondly, in this utility model, the mounting bracket at one end of the cup holder or mobile phone holder is combined with the lifting bracket. The connecting block is inserted into the connecting groove. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block, causing the locking block to drive the moving plate to compress the return spring. The locking block retracts into the cavity. Then, when the locking block moves to the locking groove, the return spring resets, the moving plate rebounds, and the locking block pops out. The locking block and the locking groove are locked together, completing the installation of the cup holder or mobile phone holder. This facilitates the installation and removal of the mobile phone holder or cup holder, making it easier to carry and use personal items, thereby improving the user experience.

Fixed brackets 2 are symmetrically fixedly connected to both ends of the load-bearing stair body 1. A fixed column 5 is fixedly connected to the top of the load-bearing stair body 1. A receiving cavity 3 is opened inside the load-bearing stair body 1. A cylinder 4 is installed at the bottom of the receiving cavity 3. An installation column 8 is provided at the top of the fixed column 5. A moving groove 6 is opened at the top of the fixed column 5 and the bottom of the installation column 8. The moving groove 6 communicates with the inside of the receiving cavity 3. A pushing column 7 is fixedly connected to the telescopic end of the cylinder 4. The other end of the pushing column 7 is fixedly connected to one end of the moving groove 6 inside the installation column 8. The movable slot 6 has a sliding connection inside. The upper end of the fixed frame 2 is slidably connected to the armrest 12. The upper end of the mounting column 8 is equipped with a control panel 11. One end of the armrest 12 is movably connected to a cup holder 25 and a mobile phone holder 26. The cup holder 25 and the mobile phone holder 26 are equipped with a fixing component 20 near the end of the armrest 12. According to the user's height and body shape, the cylinder 4 is activated through the control panel 11. The cylinder 4 pushes the pushing column 7 upward. During the upward movement of the pushing column 7, the pushing column 7 slides inside the movable slot 6. The pushing column 7 pushes the mounting column 8 upward. During the upward movement of the mounting column 8, the mounting column 8 drives the armrest 12 to rise, thus completing the height adjustment of the armrest 12.

[0021] refer to Figure 2The moving groove 6 has symmetrical fixed connections of positioning blocks 23 at both ends, and the pushing column 7 has symmetrical positioning grooves 24 at both ends. The positioning blocks 23 and the positioning grooves 24 are slidably connected. When the pushing column 7 slides inside the moving groove 6, the pushing column 7 drives the positioning grooves 24 to slide outside the positioning blocks 23.

[0022] refer to Figure 3 The shock absorption assembly 15 includes an internal hole 153, a shock absorption seat 151, a first limiting post 152, an internal hole 153, a second limiting post 154, and a first shock absorption spring 155. The bottom end of the load-bearing staircase body 1 is symmetrically provided with mounting grooves 14. The upper end of the mounting groove 14 and the upper end of the base 13 are symmetrically fixedly connected to the shock absorption seat 151. The upper end of the shock absorption seat 151 at the upper end of the base 13 is fixedly connected to the first limiting post 152. The upper end of the first limiting post 152 has an internal hole 153. The bottom end of the internal hole 153 is fixedly connected to the first shock absorption spring 155. The other end of the first shock absorption spring 155 is fixedly connected to the second limiting post 154. The second limiting post 154 is slidably connected to the internal hole 153.

The first limiting post 152 and the second limiting post 154 are both fitted with second shock-absorbing springs 16. The two ends of the second shock-absorbing springs 16 are fixedly connected to the opposite ends of the shock-absorbing seat 151. When the load-bearing staircase body is running, the vibration and impact force generated causes the load-bearing staircase body 1 to drive the second limiting post 154 to descend inside the built-in hole 153. The second limiting post 154 presses against the first shock-absorbing spring 155, and the first shock-absorbing spring 155 is compressed. At the same time, the shock-absorbing seat 151 inside the mounting groove 14 presses against the shock-absorbing seat 151 at the upper end of the base 13, causing the second shock-absorbing spring 16 to be compressed, thereby absorbing and dispersing the vibration and impact force generated by the load-bearing staircase body 1 during operation.

[0023] refer to Figure 4The fixing component 20 includes a cavity 201, a return spring 202, a moving plate 203, and a locking block 204.

A connecting block 18 is fixedly connected to the end of the mounting bracket 17 near the armrest frame 12. A cavity 201 is formed inside the connecting block 18. A return spring 202 is fixedly connected to one end of the cavity 201. A moving plate 203 is fixedly connected to the other end of the return spring 202. The moving plate 203 is slidably connected to the cavity 201. A locking block 204 is fixedly connected to the end of the moving plate 203 away from the return spring 202. The other end of the locking block 204 extends out of one end of the connecting block 18. A connecting groove 19 is formed at one end of the armrest frame 12. The connecting groove 19 connects to the connecting block 18. Block 18 is a plug-in connector. One end of the connecting groove 19 has a locking groove 21. The locking groove 21 and the locking block 204 are snap-fitted together. The mounting bracket 17 of one end of the cup holder 25 or mobile phone holder 26 is combined with the lifting frame. The connecting block 18 is inserted into the connecting groove 19. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block 204, causing the locking block 204 to drive the moving plate 203 to compress the return spring 202. The locking block 204 retracts into the cavity 201. Then, when the locking block 204 moves to the locking groove 21, the return spring 202 returns to its original position, and the moving plate 203 rebounds, causing the locking block 204 to pop out. The locking block 204 is snap-fitted into the locking groove 21 to fix it, thus completing the installation of the cup holder 25 or mobile phone holder 26.

[0024] refer to Figure 4 An unlocking block 22 is slidably connected inside the locking groove 21. The end of the unlocking block 22 away from the locking block 204 extends out of the armrest frame 12. Limiting blocks 10 are symmetrically fixedly connected at both ends of the unlocking block 22. Limiting grooves 9 are symmetrically opened inside the locking groove 21. The limiting grooves 9 and the limiting blocks 10 are slidably connected. Pushing the unlocking block 22 causes it to slide inside the locking groove 21. At the same time, the limiting blocks 10 slide inside the limiting grooves 9. The unlocking block 22 pushes the locking block 204, causing the locking block 204 to drive the moving plate 203 to compress the return spring 202. The locking block 204 retracts into the cavity 201, and the locking block 204 and the locking groove 21 are no longer engaged. Then, the cup holder 25 or the mobile phone holder 26 is pulled outwards, so that the connecting block 18 and the connecting groove 19 are no longer engaged, thus completing the disassembly of the cup holder 25 or the mobile phone holder 26.

[0025] Operating principle and advantages: First, the mounting bracket 17 at one end of the cup holder 25 or mobile phone holder 26 is combined with the lifting frame. The connecting block 18 is inserted into the connecting groove 19. During insertion, the squeezing force applies pressure to the inclined surface of the locking block 204, causing the locking block 204 to drive the moving plate 203 to compress the return spring 202. The locking block 204 retracts into the cavity 201. Then, when the locking block 204 moves to the locking groove 21, the return spring 202 resets, and the moving plate 203 rebounds, causing the locking block 204 to pop out. The locking block 204 then engages with the locking groove 21. After fixing, the cup holder 25 or mobile phone holder 26 is installed. Then, according to the user's height and body shape, the cylinder 4 is started through the control panel 11. The cylinder 4 pushes the push column 7 upward. During the upward movement of the push column 7, the push column 7 slides inside the moving groove 6. The push column 7 drives the positioning groove 24 to slide outside the positioning block 23. The push column 7 pushes the mounting column 8 upward. During the upward movement of the mounting column 8, the mounting column 8 drives the armrest frame 12 to rise, thus completing the height adjustment of the armrest frame 12.

[0026] This invention can be adjusted according to the user's height and operating habits, thus providing a more comfortable user experience, helping to reduce fatigue caused by long-term operation, and facilitating the installation and removal of the phone holder 26 or cup holder 25, making it easier to carry and use personal items, thereby improving the user experience.
