Description

Technical Field

[0001] This utility model relates to the field of logistics transfer vehicle technology, specifically to an expandable foldable logistics transfer vehicle. Background Technology

[0002] Currently, existing logistics transfer vehicles are generally constructed as follows: multiple wheels are mounted on the underside of a chassis, and a foldable push rod is installed at the rear of the chassis. In use, goods are placed on the chassis and securely tied with ropes before being transferred.

[0003] However, it is not difficult to see that the existing logistics carts still have the following shortcomings in use:

[0004] 1. After the goods are placed on the logistics cart, they need to be secured with ropes before they can be transferred. This reduces the efficiency of logistics cargo transfer.

[0005] 2. The size of logistics trolleys is generally fixed. When there are many goods to be transferred, more transfers are required, leading to low efficiency in the logistics cargo transfer process. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide an expandable foldable logistics transfer vehicle, which can achieve more efficient transfer of logistics goods when in use.

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0008] Expandable foldable logistics transfer vehicles, including:

[0009] The mobile base includes a base frame, slats, and wheels; after multiple wheels are installed at the bottom of the base frame, slats are connected to the left and right sides by splicing structures, and the distance between the slats and the base frame is adjustable;

[0010] The side panel frame has a pair of mirror images on the left and right sides, and each of them can be folded up and installed on the two slats.

[0011] The side railings are adjustable in length, and the front and rear sides of the two side panels are detachably connected by the side railings.

[0012] As an improvement, the splicing structure includes splicing rods and handle screws; splicing rods are fixed to the front and rear sides of the slats respectively, and the splicing rods are also fixed to the side of the base plate frame by handle screws. A set of matching positioning screw holes is provided on the front and rear sides of the base plate frame corresponding to each handle screw, and each set includes multiple positioning screw holes evenly arranged laterally. This makes the size of the movable base adjustable.

[0013] As an improvement, the side panel frame includes vertical tubes, crossbeams, and nylon ropes. After a pair of vertical tubes and a pair of crossbeams form a square frame structure, the nylon ropes are connected between the two crossbeams and are evenly distributed in multiple locations along the front-to-back direction. A cylindrical column, penetrating and fixed to the slats, overlaps the lower side of the vertical tube, and the bottom is hinged to the side of the slats via ear plates. The nylon ropes are designed to bend and deform within a small range according to the needs of cargo loading.

[0014] As an improvement, after the top of the cylindrical column is closed, an insert block is formed at the closed end. After the two cylindrical columns overlap, the insert block is inserted into the upper cylindrical column. A conical expansion opening is also formed at the bottom of the cylindrical column. After the side plate frame is folded and placed on the movable base, multiple of this invention can be stacked together. When stacking, the insertion and cooperation of adjacent cylindrical columns makes the stacking more secure.

[0015] As an improvement, the side panel frame also includes an inverted U-shaped rod and a second handle screw; the two sides of the inverted U-shaped rod are respectively movably sleeved inside two vertical tubes on the same side panel frame, and fixed inside the vertical tubes by the second handle screw. This makes the size of the side panel frame adjustable.

[0016] As an improvement, the side railing includes a left railing, a right railing, and three handle screws; the left and right railings are arranged one-to-one and connected together by the three handle screws. The right railing has multiple positioning screw holes that respectively engage with the three handle screws. The left end of the left railing is detachably connected to the left side panel frame, and the right end of the right railing is detachably connected to the right side panel frame. This allows for side restraint of goods loaded on this new type of railing.

[0017] The advantages of this utility model compared with the prior art are as follows:

[0018] 1. When this new type of vehicle is in use, after the logistics transfer vehicle is fully loaded with goods, the side panels and side rails work together to provide effective lateral obstruction, so that the goods can be transferred stably without additional binding. This makes the cargo transfer work more time-saving and labor-saving.

[0019] 2. In use, the size of the movable base and the side panel frame are adjustable, allowing for easy adjustment of the capacity. This significantly improves transport efficiency when more goods need to be transferred. Attached Figure Description
