Description

Technical Field

[0001] The utility model relates to the technical field of truck accessories and equipment, in particular to a temporary ladder used for a van. Background Art

[0002] A van is a type of commercial vehicle with an independent closed structure compartment or an integral closed structure compartment integrated with a cab, which is mainly used for carrying goods. Vans have the advantages of flexibility, easy operation, high efficiency, large transportation volume, full use of space, safety, and reliability; but vans also have some disadvantages in actual use: 1. Since the container behind the vehicle has a certain height, workers are required to carry it manually in some places where forklifts cannot be used. It is extremely inconvenient for workers to go back and forth between the ground and the container, resulting in slow loading and inconvenience. 2. Since many goods are heavy when workers load and unload goods, it is easy to slip when ordinary horizontal boards are tilted as temporary ladders, and the connection between the temporary ladder and the container is not firm, and it is easy to cause the horizontal board to fall. The above has become a lot of troubles for loading and unloading trucks. In order to solve the above problems, the inventor proposes a temporary ladder for vans to solve this problem. By setting a detachable temporary staircase on the rear side of the truck, it is convenient for workers to load and unload goods back and forth, and the structure is firm and not easy to fall off.

[0003] In order to facilitate the workers to get on and off the carriage to carry goods, a Chinese patent application, announcement number: CN214001478U, discloses a hydrogen fuel cell refrigerated vehicle, the utility model includes a vehicle body, a carriage is arranged on the vehicle body, a side door is arranged on the carriage, a ladder is detachably placed at the side door, the ladder includes two parallel support plates, a plurality of pedals are rotatably supported between the two support plates, and a limit assembly for limiting the rotation of the pedals is also arranged on the support plate. The utility model has the effect of facilitating the workers to get on and off the carriage to carry goods by arranging the ladder.

[0004] This solution still has some shortcomings in application. Due to the different heights of different vans, the height needs to be adjusted according to the height of the van, otherwise the ladder will not be applicable. In addition, after the height of the ladder is adjusted, the turning angle of the steps also needs to be adjusted, otherwise it will tilt and become impossible to walk. At the same time, the ladder itself has a certain weight and needs to be easy to carry. Therefore, it is necessary to improve the structure of the upper and lower ladders on the truck so that it can adjust the height and improve applicability. It is also convenient for workers to move and better carry goods. Utility Model Content
