Description

Technical Field

[0001] The utility model relates to the field of storage and transportation vehicles, in particular to a logistics storage trolley with a locking device. Background Art

[0002] In the existing express delivery transportation, after the express delivery loaded on the truck arrives at the transportation terminal, most of them are transferred to the transit warehouse or terminal warehouse by a pallet truck or a forklift. The transfer speed is not fast enough to meet the transfer needs of a large number of express deliveries. The existing storage trolley lacks small doors arranged vertically on the front wall, making it difficult to quickly take out multiple express parcels in layers. Even if a product is provided with small doors for layers, the small doors on the top layer are easy to loosen and fall off during the transfer process. For example, the utility model patent with publication number CN 210028816U provides a storage trolley, which includes a bottom plate, a plurality of movable wheels arranged on the bottom plate, and two side frames arranged oppositely on the bottom plate. At least two fixing plates are respectively arranged on each side frame, and each of the fixing plates has at least one slide rail. The partition is detachably arranged on the slide rail. The storage trolley lacks small doors arranged vertically on the side wall, and the front frame needs to be opened when only taking and placing items on the upper or middle layer. Utility Model Content

[0003] The utility model aims to provide a logistics storage trolley with a locking device to solve the problems mentioned in the background technology.

[0004] To achieve the above purpose, the technical solution adopted is: a logistics storage trolley with a locking device, including a chassis, a front wall, side walls and rear walls extending upward from the chassis, and universal wheels fixed under the chassis, the front wall is composed of a number of small doors arranged longitudinally, the small doors are fixed to the side walls by a locking device, the locking device is composed of a dividing pin and a step plate, the side walls are formed with a U-shaped tube as a frame, and the ears on both sides of the U-shaped tube and the small door are provided with holes for the dividing pin to pass through the step plate to fix the ears on the U-shaped tube. When picking up and placing express delivery, the removed small door can be hung on the side wall by the ear.

[0005] As a further improvement, the chassis is detachably connected to the side wall via latch structures at four corners.

[0006] As a further improvement, the latch structure is composed of a latch pin and a latch pin seat, and the latch pin can be inserted into a hole provided at the lower portion of the side wall.

[0007] Specifically, the side wall and the rear wall are connected via a snap-fit ​​structure, the side wall can be rotated relative to the rear wall using the snap-fit ​​structure, and the snap-fit ​​structure is fixed in the middle by bolts.

[0008] Compared with the prior art, the utility model has the beneficial effect that the efficiency of express delivery is improved by setting up multiple layers of small doors. At the same time, the small doors can be better fixed by the locking device to prevent them from falling off during transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further explained and illustrated below in conjunction with the accompanying drawings and embodiments.

[0017] Example: Figure 1-Figure 3 As shown, a logistics storage trolley with a locking device includes a chassis 1, a front wall 3 extending upward from all sides of the chassis 1, a side wall 2 and a rear wall, and a universal wheel fixed below the chassis 1. The front wall 3 is composed of four small doors arranged longitudinally, and the small door is fixed to the side wall 2 by a locking device 4. The locking device 4 is composed of a dividing pin 6 and a step plate 7. The side wall 2 is formed as a frame of a U-shaped tube. The ears 8 on both sides of the U-shaped tube and the small door are provided with holes for the dividing pin 6 to pass through the step plate 7 to fix the ears 8 to the U-shaped tube. The side wall 2 and the rear wall are connected by a snap-fit ​​structure 5, and the side wall 2 can rotate relative to the rear wall by using the snap-fit ​​structure 5. The snap-fit ​​structure 5 is fixed in the middle by a bolt 9.

[0018] like Figure 5 As shown, when taking a parcel from the storage trolley, the indexing pin 6 can be unscrewed, the small doors can be removed layer by layer, and the removed small doors can be rotated 90 degrees and hung on the side wall.

[0019] like Figure 4 and Figure 6 As shown, the chassis 1 is connected to the side wall 2 through the latch structures 10 at the four corners. The latch structure 10 is composed of a latch 11 and a latch seat 12. The latch 11 can be inserted into a hole set at the lower part of the side wall. When the storage trolley is not in use, the latch 11 can be pulled out, the chassis 1 can be removed, and then the side wall 2 can be rotated and folded onto the rear wall using the snap-fit ​​structure 5 to save storage space.

[0020] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary, but not restrictive, and the scope of the present invention is defined by the appended claims rather than the above explanations and descriptions, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. At the same time, any figure mark in the claims should not be regarded as limiting the claims involved.
