Detailed Implementation

[0032] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0034] The specific embodiments of this utility model are as follows:

[0035] like Figures 1-7 As shown, this embodiment provides a movable storage cart, including:

[0036] The support frame includes two support components arranged symmetrically on the left and right. Each support component includes multiple support rods 3 spaced apart front and back. The support rods 3 are usually made of metal. At least one support rod 3 in each support component is connected to a roller 4 at its lower end. To ensure the stability of the trolley, in this embodiment, each support component includes two support rods 3 arranged side by side front and back. Each support rod 3 is connected to a roller 4 at its lower end. The roller 4 is a universal wheel with brakes. To further save packaging volume, the roller 4 is detachably connected to the support rod 3.

[0037] A storage assembly is disposed between two support assemblies. The storage assembly includes multiple vertically spaced storage trays 1. Each storage tray 1 includes a tray 11 and side plates 12 symmetrically arranged on the left and right sides of the tray 11. The side plates 12 extend upward beyond the upper end of the tray 11 to form a receiving area for placing items. The corresponding support assembly is pre-welded and fixed to the multiple vertically spaced side plates 12 on the left or right side to form a side assembly module. In this embodiment, the support rod 3 is a cylindrical rod. To increase the contact area between the support rod 3 and the side plate 12, the side plate 12 has an inwardly concave arc-shaped surface. The support rod 3 is attached to the arc-shaped surface and then welded and fixed to the side plate 12.

[0038] This portable storage cart has a working state and a disassembled state. In the working state, the two side assembly modules are located on the left and right sides of multiple trays 11, respectively. The corresponding side panels 12 are connected and fixed to the trays 11 by screws, so that multiple storage trays 1 are positioned on the support frame 1. In the disassembled state, the corresponding side panels 12 are disassembled and separated from the trays 11, so that the two side assembly modules can be stacked side by side with the multiple trays 11. This ensures that the cart can be disassembled into multiple trays 11 and two side assembly modules during transportation. The multiple trays 11 and two side assembly modules can be stacked side by side to save packaging volume and reduce transportation costs. When the user receives the disassembled multiple trays 11 and two side support modules, he only needs to connect the corresponding side panels 12 and corresponding trays 11 on the two side support modules with screws to assemble the entire portable storage cart.

[0039] Furthermore, considering the actual usable space of the trolley, this embodiment has two storage trays 1 spaced vertically between the two supporting components. To ensure that the side panels 12 and the corresponding trays 11 are assembled with screws to form a structurally stable trolley, while also maintaining an elegant overall appearance, this embodiment employs various connection structures between the side panels 12 and trays 11 of the upper storage tray 1, and between the side panels 12 and trays 11 of the lower storage tray 1, such as... Figures 3-4 As shown, the lower end of the side plate 12 of the lower storage tray 1 extends inward to form a first connecting part 123. The first connecting part 123 and the side plate 12 are integrally bent into a plate. The first connecting part 123 is attached to the lower end of the support plate 11 and fixed by screws. In order to simplify the screw tightening process and reduce assembly time, a screw 2 is pre-welded to the lower end of the support plate 11. The first connecting part 123 is provided with a first through hole 124 corresponding to the position of the screw 2. There are two first through holes 124. The screw 2 passes through the first through hole 124. The lower end of the screw 2 is threaded with a locking nut 21 to lock the first connecting part 123 to the support plate 11. During assembly, it is only necessary to put the first connecting part 123 through the first through hole 124 onto the screw 2 and attach it to the lower end of the support plate 1, and then lock the locking nut 21 onto the lower end of the screw 2, eliminating the process of putting in screws and improving assembly efficiency.

[0040] Furthermore, to ensure a more stable connection between the tray 11 and the side panel 12, the front end of the tray 11 of the lower storage tray 1 also has a corresponding connection mechanism with the tray 11, such as... Figure 5As shown, the front end of the tray 11 extends upward to form a mounting plate 113, and the mounting plate 113 has two through-holes 115. The front end of the side plate 12 extends inward to form a second connecting part 121 that abuts against the front end of the mounting plate 113. The second connecting part 121 and the side plate 12 are integrally bent into a plate. The second connecting part 121 has a second through hole 122 corresponding to the position of the positioning hole 115. The screw passes through the second through hole 122 and the positioning hole 115, and the second connecting part 121 is locked to the mounting plate 113 by a nut that cooperates with the screw. While connecting the front end of the side plate 12 to the front end of the tray 11, the front end of the side assembly module 4 is fixed to the tray 11.

[0041] Furthermore, the second connecting portion 121 protruding from the mounting plate 113 affects the appearance of the front end of the cart and can easily scratch the user's hands. Therefore, to avoid this phenomenon, in this embodiment, the mounting plate 113 extends outward to form an extension portion, and the extension portion extends downward to form a vertical plate 113a. The mounting plate 113, the support plate 11, and the vertical plate 113a are integrally bent. A U-shaped groove 114 is formed between the vertical plate 113a, the extension portion, and the mounting plate 113. The second connecting portion 121 is inserted into the U-shaped groove 114. The U-shaped groove 114 can play a role in insertion and positioning, while preventing the second connecting portion 121 from protruding outward, making the overall appearance of the cart simple and elegant, and improving the safety of the cart.

[0042] Furthermore, the second connecting part 121 can also be locked onto the vertical plate 113a. For example, in this embodiment, the front end of the tray 11 of the upper storage tray 1 extends outward and forms a U-shaped plate structure with an open lower end. The U-shaped plate structure has a U-shaped groove 114 with an open lower end. The U-shaped plate structure includes a mounting plate 113 extending upward from the front end of the tray 11. The mounting plate 113 extends outward and forms an extension. The extension extends downward to form a vertical plate 113a. A positioning hole 115 is provided through the vertical plate 113a. The second connecting part 121 is provided with a second through hole 122 corresponding to the position of the positioning hole 115. The screw passes through the second through hole 122 and the positioning hole 115, and the second connecting part 121 is locked to the vertical plate 113a by a nut that cooperates with the screw. While locking the side plate 12 and the tray 11, the second connecting part 121 will not be exposed in the U-shaped groove 114.

[0043] Furthermore, in this embodiment, the lower end of the upper storage tray 1 is also fixed to the side plate 12 with screws. Specifically, the lower end of the side plate 12 extends beyond the lower end of the tray 11. A first connecting plate 13 located at the lower end of the tray 11 is installed on the inner side of the side plate 12. The first connecting plate 13 is a U-shaped bent plate, which includes a flat plate and longitudinal plates on both sides of the flat plate. The longitudinal plates are welded and fixed to the inner side of the side plate 12, so that there is an installation space between the flat plate and the side plate 12. The flat plate of the first connecting plate 13 is provided with a through hole 131. The left and right sides of the lower end of the tray 11 are provided with a second connecting plate 111. The second connecting plate 111 is provided with a clearance hole 112 corresponding to the position of the through hole 131. The screw passes through the clearance hole 112 and the through hole 131, and the first connecting plate 13 and the second connecting plate 111 are locked together by a nut that cooperates with the screw. The nut can be pre-welded to the end of the flat plate facing the side plate 12 to hide the screw connection marks and make the appearance of the trolley simple and elegant.

[0044] Furthermore, to increase the storage space of the tray 1, a drawer 5 is slidably connected to the lower end of the tray 11 in the front-back direction. In this embodiment, the drawer 5 is provided at the lower end of the tray 11 of the upper tray 1. The rear end of the upper tray 11 has a downwardly extending limiting part 117 to abut against the drawer 5 in the retracted state. The rear end of the tray 11 of the lower tray 1 has an upwardly extending rear baffle 116 to prevent items from sliding off the rear end. A sliding connection structure is provided between the drawer 5 and the tray 1. The sliding connection structure includes a guide rail 51 extending in the front-back direction inside the side plate 12, and a U-shaped bent plate open inside the guide rail 51, which is pre-welded to the inner side of the side connecting plate 13. The left and right sides of the drawer 5 are provided with sliding parts 52 that match the guide rail 51. The sliding parts 52 are located inside the U-shaped bent plate and are slidably connected to the corresponding guide rail 51 in the front-back direction.

[0045] Furthermore, the upper end of the tray 11 of the upper or lower storage tray 1 is covered with a pad 6, which acts as a cushion when items are placed in the storage tray 1. The pad 6 is made of PET plastic, which is highly durable and easy to remove from the storage tray 1 for separate cleaning.

[0046] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
