[0021] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0022] Please see Figure 1 The multifunctional material loading ladder of this utility model includes a support frame 1 and a ladder 4. A platform 2 is provided at the upper end of the support frame 1. The platform 2 can provide operators with a relatively stable, safe and convenient platform for operation, facilitating material loading and other related operations. The ladder 4 is located on one side of the support frame 1, and there are two ladders 4.

[0023] See Figure 1 , Figure 4 As shown, two ladders 4 are symmetrically arranged on both sides of the support frame 1. This symmetrical arrangement ensures that the entire loading ladder is subjected to more balanced forces during use, enhancing its structural stability. On the other hand, it also provides operators with more options for going up and down, improving the convenience and flexibility of use. A retractable assembly is provided between the lower end of the ladder 4 and the support frame 1. The retractable assembly includes a telescopic rod 5, one end of which slides with the support frame 1.

[0024] In this embodiment, the other end of the telescopic rod 5 is rotatably connected to the ladder 4 via a pivot 6. The pivot 6 allows the ladder 4 to rotate around the connection point with the telescopic rod 5 at a certain angle. In conjunction with the telescopic movement of the telescopic rod 5, the ladder 4 can flexibly adjust its angle and position according to actual usage needs. It can be retracted when not in use to save space, or extended to a suitable angle when needed to facilitate climbing.

[0025] See Figure 1 , Figure 2 , Figure 4As shown, a fixing component is provided between the support frame 1 and the telescopic rod 5. The fixing component includes a fixing bolt 8, which is slidably mounted on the support frame 1. The telescopic rod 5 is provided with fixing holes 9, and there are at least two fixing holes 9. The two fixing holes 9 are located at both ends of the telescopic rod 5. The fixing bolt 8 is inserted into the fixing hole 9. Through the insertion and cooperation between the fixing bolt 8 and the fixing hole 9, the relative position of the telescopic rod 5 and the support frame 1 can be fixed when needed, ensuring that the ladder 4 remains stable and reliable during use and avoiding accidental shaking or displacement.

[0026] See Figure 1 , Figure 3 , Figure 4 As shown, a lifting assembly is provided between the upper end of the ladder 4 and the support frame 1. The lifting assembly includes a sliding plate 3, which is slidably mounted on the support frame 1. The sliding plate 3 and the ladder 4 are rotatably connected by a pivot 7. A vertical plate 10 is provided on the sliding plate 3, and a limit plate 11 is provided on the outer side of the vertical plate 10. The limit plate 11 is installed on the support frame 1. A guardrail 14 is provided on the ladder 4, which is rotatably connected to the ladder 4. A fixing bolt 15 is provided on the guardrail 14.

[0027] In this embodiment, a fixing block 16 is provided on the ladder 4 at the position corresponding to the fixing bolt 2 15. The fixing bolt 2 15 and the fixing block 16 are inserted into each other, so that the guardrail 14 can be firmly fixed after it is adjusted to a suitable position, ensuring that it is always in a reliable state during the protection process, and providing effective safety protection for the operator. A sliding component is provided at the lower end of the support frame 1.

[0028] In this embodiment, the sliding assembly includes self-locking casters 12 and directional casters 13. The self-locking casters 12 are installed at the end of the telescopic rod 5 away from the support frame 1, and the directional casters 13 are installed at the four corners of the lower end of the support frame 1. The directional casters 13 mainly play the role of stabilizing support and assisting movement. They cooperate with the self-locking casters 12 to ensure that the entire loading ladder can maintain good stability and operability whether it is moving or stationary, making it convenient for users to flexibly adjust its position and carry it according to actual work needs.

[0029] The implementation principle is as follows: The lower end of the support frame 1 of the loading ladder is equipped with a sliding component, including a self-locking caster wheel 12 and a directional wheel 13. When the loading ladder needs to be moved, the workers can easily push the loading ladder to the designated position required for the work with the help of the self-locking caster wheel 12 and the directional wheel 13. After reaching the destination, the self-locking caster wheel 12 is locked to prevent the loading ladder from sliding during subsequent use.

[0030] First, loosen the fixing bolt 8 in the fixing component to allow the telescopic rod 5 to slide freely on the support frame 1. According to actual work requirements, pull the telescopic rod 5 out of the support frame 1 and adjust the distance between the ladder 4 and the support frame 1. After adjusting to the appropriate position, insert the fixing bolt 8 into the corresponding fixing hole 9 of the telescopic rod 5 to fix the telescopic rod 5, ensuring the stability of the ladder 4. As the ladder 4 moves, the sliding plate 3 can slide on the support frame 1, thus restricting the upper end of the sliding plate 3. The vertical plate 10 and the limiting plate 11 ensure that the sliding plate 3 remains stable during sliding, preventing it from shifting or shaking.

[0031] Unfold the guardrail 14 that is rotatably connected to the ladder 4, and then insert the fixing bolt 15 on the guardrail 14 into the corresponding fixing block 16 on the ladder 4 to secure the guardrail 14 to the ladder 4, providing safety protection for the person using the ladder 4.

[0032] When storing, pull out the second fixing bolt 15, rotate the guardrail 14 to retract it, reducing the space occupied. Then, loosen the first fixing bolt 8 again, retract the telescopic rod 5 into the support frame 1, and bring the ladder 4 as close to the support frame 1 as possible. Finally, insert the first fixing bolt 8 into the fixing hole 9 at the end of the telescopic rod 5 to secure it. Unlock the self-locking caster 12, push the loading ladder to the storage location, and lock the self-locking caster 12 to complete the storage.

[0033] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
