Description

TECHNICAL FIELD

[0001] The utility model relates to the field of trolley supporting plate adjustment, in particular to a logistics trolley supporting plate adjusting device. BACKGROUND

[0002] In the field of modern logistics transportation, efficient and accurate handling of various goods is the key to improving logistics efficiency and quality. As a common tool for short-distance handling of goods, the adaptability of the supporting plate of the logistics trolley directly affects the convenience and safety of the goods handling.

[0003] The supporting plate of the traditional logistics trolley is mostly fixed in structure, which has many drawbacks. On the one hand, the height of the supporting plate is usually not adjustable. In actual logistics scenarios, goods come from a wide range of sources and have different shapes and sizes. For example, some large equipment or stacked goods require a higher supporting plate for easy loading and unloading. Small and low goods are easier to handle at a lower supporting plate height. The fixed height of the supporting plate cannot meet these diverse needs, resulting in the need for additional manpower or auxiliary equipment to adjust the height of the goods during loading and unloading, increasing labor and time costs, and possibly damaging the goods due to multiple handling.

[0004] On the other hand, the lateral position of the supporting plate is often not movable, and lacks adjustment function for the inclination angle. When the goods are placed on the supporting plate, if the shape of the goods is irregular or the placement position is slightly offset, it may cause the center of gravity to shift, causing the supporting plate to tilt. In this case, the goods are likely to fall during transportation, which not only damages the goods but also poses a safety threat to surrounding personnel and equipment. In addition, in some scenarios where goods need to be accurately placed in a specific location, the fixed lateral position cannot meet the demand for accurate alignment, reducing the accuracy and efficiency of logistics operations. Therefore, we propose a logistics trolley supporting plate adjusting device. SUMMARY

[0014] (Three) beneficial effects

[0015] Compared with the prior art, the utility model provides a logistics trolley supporting plate adjusting device, has the following beneficial effects:

[0016] 1、 the logistics trolley supporting plate adjusting device, through setting two adjusting electric telescopic rods of the base top, can according to the actual height demand of goods, the height of supporting plate is conveniently and quickly adjusted.

[0017] 2、The logistics trolley supporting plate adjusting device, the design of the displacement structure, including two rectangular mounting blocks, a screw rod and a connecting assembly, enables the supporting plate to move horizontally. When it is necessary to place the goods accurately at a specific position, the operator only needs to rotate the rotating block, drive the screw rod to rotate, and then drive the threaded connecting block to move the supporting plate horizontally, so as to realize accurate alignment. This function improves the accuracy and efficiency of logistics operation, and avoids the problem of deviation of goods placement caused by the fixed position of the supporting plate.

[0018] 3、The logistics trolley supporting plate adjusting device, the hinged design of the connecting block and the threaded connecting block, and the setting of the threaded pipe and the supporting bolt in the supporting structure enable the supporting plate to automatically swing according to the unbalanced condition of goods placement, and the inclination angle of the supporting plate is adjusted by rotating the supporting bolt. When irregular-shaped goods or goods with slight deviation are placed, the supporting plate will not cause the goods to slide off due to the deviation of the center of gravity, effectively ensuring the stability and safety of the goods during transportation, and reducing the possibility of damage to the goods and safety threats to surrounding personnel and equipment.

[0019] 4、The logistics trolley supporting plate adjusting device, the sliding clamping of the side grooves on both sides of the bearing plate and the sliding protrusions on the bent connecting plate ensures that the supporting plate can move horizontally flexibly, provides stable guidance and support for the entire displacement structure, and enhances the stability of the device during operation.

[0020] 5、The logistics trolley supporting plate adjusting device, the operation of the entire adjusting device is relatively simple, and the skill requirement of the operator is not high. To adjust the height of the supporting plate, only the adjusting electric telescopic rod needs to be started; when adjusting the horizontal position, the rotating block can be manually rotated; and to adjust the inclination angle, the supporting bolt can be rotated. This simple and easy-to-understand operation mode reduces the training cost of the operator and improves the overall efficiency of logistics operation. BRIEF DESCRIPTION OF DRAWINGS
