[0015] Example 1; as Figure 1-3As shown, the present invention proposes a warehouse logistics staircase structure, including a tread frame 1, a handrail frame 2, a traction component, a slide rail, a sliding component, and a cargo box 4. The handrail frame 2 is located at the top edge of the tread frame 1, wherein the bends at both top sides of the handrail frame 2 are arc-shaped. A slide rail is provided at the inner top of the handrail frame 2, above the side of the tread frame 1, for guiding goods in use. The sliding component is located on the slide rail, and a cargo box 4 is provided on the side of the sliding component for holding goods in use. The cargo box 4 can be replaced with a storage bag in use to improve the convenience of goods transportation. The width of the cargo box 4 is half that of the tread frame 1, so that when the cargo box 4 is installed on the mounting plate 5, the staff can use the tread frame 1 from the side of the cargo box 4. The traction component is installed on the tread frame 1 and the handrail frame 2, and its end is connected to the sliding component. It is used to limit the position of the sliding component on the slide rail in use, and to move the sliding component towards the end of the handrail frame 2 and reset it.

[0016] In this embodiment, the sliding component is installed on the slide rail and connected to the traction component. First, the traction component pulls the sliding component, causing it to move above the top of the pedal frame 1 on the slide rail, and causing the sliding component to move the cargo box 4 synchronously. At the same time, by precisely controlling the traction component, the traction component places the sliding component at different heights on the slide rail, allowing goods on shelves of different heights to be taken out and placed inside the cargo box 4 or on shelves of different heights, making it more convenient to pick up and put down goods. Meanwhile, by controlling the traction component to slowly release the sliding component, and by tilting the top of the side of the handrail 2, the sliding component slowly moves down the slide rail to the lowest point of the slide rail by gravity. Workers can then safely take out the goods in the cargo box 4 from the bottom of the stairs without having to carry heavy objects up and down the stairs, significantly improving the safety of unloading operations.

[0017] Example 2; as Figure 3 As shown, the present invention proposes a warehouse logistics staircase structure. Compared with Embodiment 1, the difference in this embodiment is that the slide rail includes a track 6 and a fixing plate 16. The fixing plate 16 is installed on the inner top of the handrail frame 2. The fixing plate 16 is arranged to match the dimensions of the top side of the handrail frame 2, so as to fix the fixing plate 16 on the top side of the handrail frame 2, avoid gaps, and improve the installation strength of the fixing plate 16. The track 6 is installed on the top of the fixing plate 16, wherein the bottom end of the track 6 is fitted and connected to the top of the fixing plate 16, and the top dimension of the track 6 is arranged to match the dimension of the fixing plate 16.

[0018] In this embodiment, a fixing plate 16 is provided on the side of the handrail 2 according to the top shape of the handrail 2, and a track 6 is provided on the top of the fixing plate 16, so that the sliding component installed on the track 6 moves along the top of the side of the handrail 2, making the use of the sliding component more convenient.

[0019] Example 3; as Figure 3 As shown, this utility model proposes a warehouse logistics staircase structure. Compared to Embodiment 1, the difference lies in that the sliding assembly includes a mounting plate 5, second pulleys 11, and a connecting ring 12. There are at least two second pulleys 11, which are rotatably mounted on the top of the track 6. The mounting plate 5 is mounted on the two second pulleys 11, and the connecting ring 12 is mounted on one end of the mounting plate 5 and connected to the traction assembly. During use, the mounting plate 5 connects the two second pulleys 11 into a single unit, causing them to roll on the track 6 and simultaneously drive... The mounting plate 5 moves along the track 6. A roller 13 is provided on the bottom side of the mounting plate 5 and below the fixing plate 16. Two baffles 14 are provided at the bottom of the fixing plate 16. The two baffles 14 and the fixing plate 16 enclose a slide 15. The top of the roller 13 is located inside the slide 15. When the mounting plate 5 moves along the track 6, the mounting plate 5 drives the roller 13 to roll inside the slide 15. The cooperation between the roller 13 and the baffles 14 limits the mounting plate 5 and the second pulley 11, preventing the mounting plate 5 and the second pulley 11 from shifting or falling off.

[0020] In an optional embodiment, a support rod 9 is provided on the other side of the mounting plate 5, and a connecting hole 10 is provided on the top side of the cargo box 4. The support rod 9 is inserted into the inner side of the connecting hole 10, and is used to hang the cargo box 4 on the mounting plate 5 through the cooperation of the support rod 9 and the connecting hole 10. The support rod 9 is rotatably connected to the cargo box 4 through the connecting hole 10, so that when the mounting plate 5 moves along the handrail 2, the cargo box 4 is always placed in a vertical state by gravity, so as to prevent the cargo box 4 from tilting and causing the goods to fall off.

[0021] In an optional embodiment, the projected shape of the support rod 9 is T-shaped, and the shape of the connecting hole 10 is gourd-shaped. This is used to move the support rod 9 from the large-diameter hole to the small-diameter hole of the connecting hole 10 during use, so that the position of the cargo box 4 is limited on the support rod 9, and the cargo box 4 is prevented from falling off the support rod 9.

[0022] In this embodiment, the top side of the mounting plate 5 inside the second pulley 11 is positioned, and the roller 13 is mounted on the side of the mounting plate 5 and located below the second pulley 11. The mounting plate 5 drives the second pulley 11 to roll and connect with the track 6. The top of the roller 13 is placed in the slide 15. When the traction rope 7 pulls the mounting plate 5 through the connecting ring 12, the mounting plate 5 drives the second pulley 11 to roll on the track 6. The mounting plate 5 drives the cargo box 4 to move synchronously through the support rod 9, so that the cargo box 4 moves along the track 6. At the same time, the mounting plate 5 drives the roller 13 to roll inside the slide 15. The cooperation between the roller 13 and the second pulley 11 limits the mounting plate 5 and prevents the mounting plate 5 from causing the second pulley 11 to deviate and fall off.

[0023] Example 4; as Figure 2 As shown, the present invention proposes a warehouse logistics staircase structure. Compared with Embodiment 1, the difference in this embodiment is that the traction component includes a winch 3, a traction rope 7, and a first pulley 8. One end of the traction rope 7 is connected to a connecting ring 12. The winch 3 is installed at the top of the pedal frame 1. There are at least two first pulleys 8, both of which are installed on one side of the handrail frame 2. The other end of the traction rope 7 is wound around the winch 3 and placed in the first pulley 8 for rolling connection. The winch 3 can be set at the top inner side of the pedal frame 1, and a through hole is opened at the top of the pedal frame 1 so that the traction rope 7 extends through the through hole to the top of the pedal frame 1, reducing the space occupied at the top of the pedal frame 1.

[0024] In this embodiment, the two ends of the traction rope 7 are connected to the connecting ring 12 and the winch 3 respectively. The movement of the end of the traction rope 7 is redirected by the first pulley 8. When it is necessary to move the cargo box 4 to the top of the pedal frame 1, the winch 3 starts to continue winding the traction rope 7, and the traction rope 7 drives the mounting plate 5 to move on the track 6 via the second pulley 11 on the first pulley 8. This causes the mounting plate 5 to drive the cargo box 4 to move upward on the pedal frame 1 via the support rod 9. When it is necessary to unload the cargo or place the cargo box 4 in the middle of the handrail frame 2, the winch 3 releases the traction rope 7, causing the second pulley 11 of the cargo box 4 to slide on the track 6 due to the inclined arrangement of the handrail frame 2 and the action of gravity. This allows the cargo box 4 to be placed in different positions on the side of the handrail frame 2, enabling the loading and unloading of goods at different heights.

[0025] In this invention, the two ends of the traction rope 7 are connected to the connecting ring 12 and the winch 3, respectively. The movement of the end of the traction rope 7 is redirected by the first pulley 8. When it is necessary to move the cargo box 4 above the top of the pedal frame 1, the winch 3 starts to continue winding the traction rope 7, and the traction rope 7 pulls the mounting plate 5 on the first pulley 8 through the connecting ring 12. The mounting plate 5 moves on the track 6 through the second pulley 11, and the mounting plate 5 drives the cargo box 4 to move upwards on the pedal frame 1 through the support rod 9. At the same time, the winch 3 is precisely controlled so that the winch 3 controls the winding length of the traction rope 7, thereby making the traction rope 7 move the mounting plate 5 on the track 6. The position is controlled so that the mounting plate 5, through the support rod 9, places the cargo box 4 at different heights on the track 6, thereby allowing goods on shelves of different heights to be taken out and placed inside the cargo box 4, or goods in the cargo box 4 to be placed on shelves of different heights, making the retrieval and placement of goods more convenient. At the same time, the winch 3 is controlled to slowly unwind the traction rope 7, so that the mounting plate 5, through gravity and the inclined shape of the track 6, drives the second pulley 11 to move to the lowest end of the track 6. Workers can then safely take out the goods in the cargo box 4 from the bottom of the stairs without having to carry heavy objects up and down the stairs, significantly improving the safety of unloading operations and preventing damage to the goods in the cargo box 4.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
