By rotating a handwheel, the upper push plate moves upward, lifting the material at the bottom of the trolley body. Simultaneously, the upper push plate moves the right push plate to the right, causing the material to accumulate upwards and to the right, making it easier for workers to retrieve the material from the bottom.

[0004] While the aforementioned material handling device can lift the material at the bottom of the trolley upwards and push it to the right to pile it up for easy access by workers, its internal multi-worm gear transmission mechanism has a complex structure and requires high precision in parts machining, leading to higher production costs. Because this transmission mechanism requires high precision to ensure reliable transmission, it is prone to rapid wear due to high loads and frequent rotation during use, thus affecting its performance and requiring frequent maintenance, which further increases operating costs. Therefore, to address these issues, a convenient loading and unloading material handling device is proposed. Utility Model Content

[0005] To address the technical problem that the transmission structure used to adjust the height of the material handling part in the comparative technology is complex and requires high precision, which significantly increases its operating cost, this utility model provides a convenient loading and unloading material handling device.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is: A convenient loading and unloading material handling device includes an outer frame with a movable linkage lifting platform installed inside. The linkage lifting platform includes a pallet and two symmetrically arranged end plates. Linkage grooves are formed on both sides of the pallet.

[0014] In summary, this utility model has the following beneficial technical effects: The linkage lifting platform consists of a pallet and two symmetrically arranged end plates. This design allows the pallet to move up and down while driving the rotating shaft at the bottom of the end plates to slide in the linkage groove. As the pallet moves up, the bottom ends of the end plates move closer together to gather the materials, making it easier for workers to pick up the materials. In addition, the above structure is simple to construct, which can significantly reduce costs and reduce the failure rate during use. In addition, the height of the pallet can be manually adjusted by locking the slider. In conjunction with this, the multi-stage height locking mechanism enables multi-stage adjustment and stable locking of the pallet height, meeting the requirements for material handling height in different scenarios.

[0017] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: like Figure 1 - Figure 2As shown in the figure, the material handling device for easy loading and unloading provided in this embodiment mainly includes an outer frame 1, inside which a movable linkage lifting platform 2 is installed. The outer frame 1 provides a stable support structure for the entire device, while the linkage lifting platform 2 is used to carry materials and realize the lifting function.

[0018] Among them, such as Figure 2 As shown, the linkage lifting platform 2 consists of a pallet 21 and two symmetrically arranged end plates 22. Linkage grooves 23 are provided on both sides of the pallet 21. Rotating shafts are fixedly installed at both the upper and lower ends of the end plates 22. The upper rotating shaft is rotatably connected to the outer frame 1, and the lower rotating shaft is slidably connected to the linkage groove 23. This design allows the pallet 21 to drive the rotating shaft at the bottom of the end plate 22 to slide in the linkage groove 23 while moving up and down. Thus, when the pallet 21 moves up, the bottom ends of the end plates 22 move closer to each other to gather the material.

[0019] To ensure the proper functioning of the above features, this embodiment also includes a height adjustment and locking mechanism, which comprises the following components.

[0020] Sliding groove 12 and locking slider 24, as Figure 2 As shown, sliding grooves 12 are provided on both sides of the outer frame 1, and locking sliders 24 are fixedly provided on both sides of the support plate 21 and slidably disposed in the sliding grooves 12. The locking sliders 24 can move up and down in the sliding grooves 12, thereby realizing the initial adjustment of the height of the support plate 21. The multi-stage height locking mechanism 3 is installed on both sides of the sliding groove 12, such as... Figure 3 - Figure 4 As shown, it includes a movable bolt 32 and a guide cover plate 31. The locking slider 24 has slots 241 on both sides. The multi-level height locking mechanism 3 includes several arrayed guide covers 31, in which movable bolts 32 corresponding to the slots 241 are slidably arranged. When the locking slider 24 moves to a suitable height, the movable bolts 32 can be inserted into the slots 241 to lock the height of the support plate 21. The multi-level height locking mechanism 3 also includes a plate base 33 disposed on the rear side of the movable bolt 32. The rear end of the movable bolt 32 is slidably connected to the plate base 33, and a spring 34 is sleeved on the rear end of the movable bolt 32. The spring 34 provides elastic force to the movable bolt 32 so that it can be stably inserted into the slot 241.

[0021] In addition, such as Figure 3 - Figure 4As shown, the multi-level height locking mechanism 3 also includes a reset assembly 35, which includes a reset plate 352 movably sleeved on the rear of the movable bolt 32 and an end cap 351 fixedly installed on the rear end of the movable bolt 32. An outer pull buckle plate 353 is fixedly installed on the reset plate 352, and a protrusion for locking the outer pull buckle plate 353 is fixedly installed on the outer wall of the outer frame 1. When it is necessary to reset the support plate 21 to the bottom, the outer pull buckle plate 353 is pulled to make all the movable bolts 32 disengage from the slot 241, thereby realizing the adjustment of the height of the support plate 21.

[0022] Both sides of the top of the locking slider 24 are machined with bevels 242, and the movable bolt 32 is machined with bevels 321. This bevel design makes the movable bolt 32 more smoothly inserted into and removed from the slot 241, reducing operating resistance.

[0023] like Figure 1 - Figure 2 As shown, the outer frame 1 has symmetrically arranged guide grooves 11, which are centered on the upper rotating shaft of the end plate 22. The rotating shaft on the lower side of the end plate 22 is slidably disposed in the guide grooves 11. The guide grooves 11 provide a trajectory for the movement of the rotating shaft on the lower side of the end plate 22, ensuring the stability of the overall movement of the linkage lifting platform 2. In addition, the outer wall of the outer frame 1 is fixedly provided with a support guide rail 5 with the same trajectory as the guide groove 11. The outer end of the rotating shaft on the lower side of the end plate 22 is fixedly installed with a support roller 25, which rolls in the support guide rail 5. The design of the support guide rail 5 and the support roller 25 further enhances the stability of the device and reduces the friction during the movement.

[0024] like Figure 5 As shown, a lifting belt 4 is fixedly connected to the locking slider 24, which includes two symmetrically arranged belt bodies 41. Several arrayed insertion holes 42 are provided on the belt body 41, and an insertion shaft 43 is fixedly provided at the end of the belt body 41. The design of the insertion holes 42 and the insertion shaft 43 allows the lifting belt 4 to flexibly adjust its overall length, making it easier for the user to select the optimal height according to their own situation, and making it easier to exert force to pull up the pallet 21.

[0025] like Figure 1 As shown, a set of four casters is fixedly installed at the bottom of the outer frame 1. The casters are located at the four corners of the bottom of the outer frame 1. The set of four casters allows the entire device to move easily between different positions, improving the flexibility of the device.

[0026] The working principle and usage process of this utility model: The linkage lifting platform 2 consists of a pallet 21 and two symmetrically arranged end plates 22. This design allows the pallet 21 to move up and down while driving the rotating shaft at the bottom of the end plates 22 to slide in the linkage groove 23. When the pallet 21 moves up, the bottom ends of the end plates 22 move closer to each other, which helps to gather the materials and makes it easier for workers to pick up the materials.

[0027] When the locking slider 24 moves to the appropriate height, the movable bolt 32 can be inserted into the slot 241 to lock the height of the tray 21. The spring 34 provides elastic force to the movable bolt 32, so that it can be stably inserted into the slot 241 to fix the height of the tray 21. In addition, when it is necessary to reset the tray 21 to the bottom, pull the outer pull plate 353 to make all the movable bolts 32 disengage from the slot 241 to adjust the height of the tray 21.

[0028] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
