Description

Technical Field

[0001] The utility model relates to the technical field of logistics transportation devices, in particular to a height-adjustable logistics trolley. Background Art

[0002] Logistics trolleys, also called cargo trolleys or cage trolleys, are a type of unit mobile container equipment equipped with four casters for transporting and storing materials. They are often used in logistics distribution in large supermarkets or logistics turnover between factory processes. The products stored in logistics trolleys are displayed eye-catchingly. During transportation: on the one hand, they protect the safety of materials. On the other hand, they do not cause clutter in the sorted and equipped products. Loading and unloading is very labor-saving; the wheels are usually designed as two fixed wheels and two universal wheels for easy manual pushing. The logistics trolley can be designed to carry the weight of the goods.

[0003] Most of the existing logistics trolleys have fixed layers, so the distance between adjacent layers cannot be adjusted. When goods of different heights need to be transported, products that exceed the distance between the layers cannot be placed in the trolleys, which is very inconvenient to use. In addition, when goods are placed on the layers of the existing logistics trolleys, some goods are prone to tipping over, or overturning due to obstructions during movement, but there is no corresponding structure to protect the goods.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] Please refer to Figure 1 The utility model provides a height-adjustable logistics trolley, comprising a frame 1, wherein at least one set of layer plates 2 is sequentially arranged from top to bottom in the frame 1, wherein the layer plates 2 are detachably connected to the frame 1, and a protective belt structure 3 is arranged on one side of the layer plates 2. The protective belt structure 3 is detachably connected to the inner side wall of the frame 1. Any set of layer plates 2 includes at least 2-4 layer plates 2.

[0027] It should be noted that when the trolley needs to transport a large number of products at a time, multiple groups of layer plates 2 will be set up inside according to actual needs. The outer sides of the two groups of layer plates 2 on both sides are connected to the frame 1, and the other groups of layer plates 2 in the middle are connected to the frame 1 through one end. Therefore, when in use, the protective belt structure 3 is connected to the inner wall of the frame 1 and covers the layer plates 2, so that the goods placed on the layer plates 2 can be stably bound to the layer plates 2 or between the frame 1 and the layer plates 2, or the protective belt structure 3 is connected to the other side of the layer plates 2 to stably bind the goods to the layer plates 2. After use or when loading, the protective belt structure 3 and the frame 1 or the layer plates 2 need to be separated.

[0028] Please refer to Figure 2The frame 1 includes a bottom frame 11, a back frame 12 is provided at the rear end of the bottom frame 11, and side frames 13 are provided on both sides. The layer plate 2 is connected to the back frame 12 or the side frame 13. The bottom frame 11, the back frame 12, and the side frame 13 are all made of steel and fixed by welding or screw connection. The bottom frame 11, the back frame 12, and the side frame 13 form a stable semi-open storage compartment. A vertical rod 14 is provided in the side frame 13 or the back frame 12, and a plurality of groups of jacks 15 are provided on the vertical rod 14 from top to bottom corresponding to the layer plate 2.

[0029] Please refer to Figure 2-4 The layer board 2 includes a board body 21, which is a board with a thickness of 2-5 cm and can be made of stainless steel or wood. An avoidance angle 23 is provided on the inner side of the outer end of the board body 21. A pin-connected locking structure 22 is provided at the edge of the board body 21, and the pin-connected locking structure 22 and the vertical rod 14 are detachably connected.

[0030] The pin-joined locking structure 22 includes a ring sleeve 221, the inner shape of which is the same as the outer shape of the vertical rod 14, and is fixedly connected to the edge of the plate body 21 by welding or screw connection. The ring sleeve 221 is sleeved on the vertical rod 14 and can move up and down along the vertical rod 14 to facilitate position adjustment. A pin 222 is provided on the outer side of the ring sleeve 221, and the pin 222 is pinned into the ring sleeve 221 to pin the ring sleeve 221 and the vertical rod 14. When the position of the layer needs to be adjusted, it is only necessary to pull the pin 222 out of the ring sleeve 221, then move the ring sleeve 221 along the vertical rod 14 to a predetermined position, and then insert the pin 222 into the ring sleeve 221 to adjust the layer spacing.

[0031] Please refer to Figure 1 and Figure 5 The protective belt structure 3 includes a winding shaft 31, and the two ends of the winding shaft 31 are rotatably connected to the layer plate 2 through a connecting member 32. The connecting member 32 is a semi-annular member, one end of which extends outward to form a connecting plate 321, and the connecting plate 321 and the edge of the layer plate 2 are fixedly connected by screws. A plurality of groups of limiting rings 33 are arranged in sequence along the axial direction of the winding shaft 31. The limiting rings 33 are annular limiting plates, and binding belts 34 are arranged between adjacent groups of limiting rings 33. The binding belt 34 is wound around the winding shaft 31, and its fixed end is fixed to the winding shaft 31, and the free end is detachably connected to the inner wall of the frame 1 or the layer plate 2. The binding belt 34 adopts a high-elastic elastic belt, and its width is less than or equal to the distance between adjacent groups of annular limiting rings 33.

[0032] Specifically, a hook is provided at the free end of the binding belt 34, and the hook is hung on the frame 1 or the layer board 2 to bind the product placed on the layer board 2 or restrict the position. Generally, the hook can be directly hung on the frame 1, and the layer board 2 can be connected to the binding belt 34 and the frame 1 or the layer board 2 by opening a hole on the edge of the hole and hanging the hook in the hole.

[0033] One end of the winding shaft 31 is connected to a driving motor 35, and the driving motor 35 drives the winding shaft 31 to rotate, and the winding shaft 31 loosens or reels the binding belt 34. That is, the driving motor 35 rotates, driving the winding shaft 31 to rotate forward or reverse, thereby achieving the loosening or reeling of the binding belt 34.

[0034] Working principle:

[0035] When in use, first adjust the position of the shelf 2 according to the height of the product, then place the products on the shelf 2 in turn, then start the drive motor 35, the drive motor 35 drives the winding shaft 31 to rotate, and gradually loosens the binding belt 34 wrapped around its surface. The user pulls the free end of the binding belt 34 and hangs the hook at the free end on the frame 1 or the shelf 2 to bind the product or limit its position to prevent the product from overturning.

[0036] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
