Description

Technical Field

[0001] The utility model relates to the technical field of step ladders for getting on trucks, and specifically refers to a step ladder for getting on trucks. Background Technique

[0002] Trucks play an extremely important role in the logistics field. The large space of the truck carriage makes it rather troublesome to load and unload goods deep inside and at high positions in the truck carriage. In order to facilitate the loading and unloading of goods at high positions, truck box hanging ladders came into being.

[0003] The existing truck box hanging ladders are usually step ladders that can be hooked on the rear railing of the carriage. For example, in the solution of CN203271564U, when in use, the hook is hung on the railing of the rear carriage of the truck, and it is stable and safe to use. However, the four struts and steps of this hanging ladder are fixedly connected and cannot be folded up, occupying a large space and being inconvenient to carry and store after use. Content of the Utility Model

[0004] The purpose of the utility model is to provide a step ladder for getting on trucks to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] A step ladder for getting on trucks of the utility model includes an outer parallel ladder frame and an inner parallel ladder frame. A number of parallel pedals are provided between the outer parallel ladder frame and the inner parallel ladder frame. The pedals are rotatably connected to the outer parallel ladder frame and the inner parallel ladder frame. The outer parallel ladder frame and the inner parallel ladder frame can be pulled apart or folded through the pedals. When folded, the two ends of the outer parallel ladder frame extend beyond the inner parallel ladder frame; the top of the outer parallel ladder frame is in the shape of an inward-facing hook.

[0007] As an improvement, the bottoms of the outer parallel ladder frame and the inner parallel ladder frame are bent inward.

[0008] As an improvement, rubber pads are provided at both ends of the outer parallel ladder frame and the inner parallel ladder frame.

[0009] As an improvement, there are 2 - 5 pedals.

[0010] Compared with the prior art, the advantages of the utility model are as follows: The hook is hooked on the upper edge of the railing at the rear end of the truck box. The outer parallel ladder frame tilts backward, and the pedals naturally rotate downward to pull the inner parallel ladder frame apart, so that the rubber pads at the lower ends of the outer parallel ladder frame and the inner parallel ladder frame are both on the ground. Then, slightly move the lower ends to make the pedals horizontal, and the step ladder is set up, as shown in Figure 1 、 3 、5. After use, directly lift the outer parallel ladder frame, and then fold it together with the inner parallel ladder frame, as shown in Figure 2 、 4, 6.

[0011] This step ladder for getting on a truck can be folded and retracted. After use, it occupies little space, is convenient to carry and store, and has high practical value and popularization value. BRIEF DESCRIPTION OF THE DRAWINGS
