DETAILED DESCRIPTION
[0025] The present application provides a logistics trolley, which is surrounded by a frame structure formed by vertical rods and horizontal rods, and a flexible partition is arranged on the frame structure to replace the plate-shaped side wall to prevent the goods from falling, so that the height increasing plate is located in the gap between the adjacent two vertical rods in the storage state, without occupying the loading space inside the logistics trolley.
[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0027] As Figures 1-2 shown, the logistics trolley provided by the present application comprises:
[0028] The frame is arranged on the bottom plate 15 of the logistics trolley and surrounds the loading space with the bottom plate 15, and the frame comprises a plurality of vertical rods and horizontal rods. In an embodiment, the vertical rods comprise a first vertical rod 11, a second vertical rod 12, a third vertical rod 13 and a fourth vertical rod 14, so that the cross section surrounded by the four vertical rods is a rectangular structure. Of course, if the cross section is other shapes than rectangular, more vertical rods can be arranged as appropriate.
[0029] The horizontal rods are connected between the adjacent two vertical rods to strengthen the overall strength of the frame.
[0030] The flexible partition is arranged between the adjacent two vertical rods to prevent the goods in the loading space from falling outside the logistics trolley.
[0031] The height increasing plate is rotatably connected to the upper end of the frame. When the logistics trolley is loaded with more goods, the height increasing plate can be rotated upward and opened to be parallel to the side of the frame to increase the loading capacity. When the goods are less or the height increasing plate is not needed, the height increasing plate can be folded inward and downward to be stored in the space between the two adjacent vertical rods.
[0032] Since the express industry mainly deals with small packages, the overall weight is small, and all have soft outer packaging, the logistics trolley of the present application uses a frame structure surrounded by vertical rods and horizontal rods, and a flexible partition piece made of canvas or other flexible materials is arranged on the frame structure to prevent goods from falling from the gap of the frame, which can replace the plate-shaped side wall used in the prior art to collect and transport express packages. When the height increasing plate on the logistics trolley is in the storage state, it is located in the gap between the two adjacent vertical rods. Since there is no plate-shaped side wall in the gap between the vertical rods, the height increasing plate will not be disturbed by the plate-shaped side wall to occupy the loading space inside the logistics trolley, thereby increasing the amount of goods that can be loaded.
[0033] In a preferred embodiment, the horizontal rods include top horizontal rods connected to the top of the two adjacent vertical rods, including two top one horizontal rods 16 and two top two horizontal rods 17, which form a closed loop; one first height increasing plate 31 is rotatably connected to each of the two top one horizontal rods 16, and one second height increasing plate 32 is rotatably connected to one of the two top two horizontal rods 17.
[0034] The top horizontal rods can connect the vertical rods together to increase the overall strength of the frame, and also can provide a basis for the rotation connection of the height increasing plate.
[0035] In a preferred embodiment, the horizontal rods further include middle horizontal rods connected to the middle of the two adjacent vertical rods, as shown in Figure 1 The middle horizontal rods include a middle one horizontal rod 18 and a middle two horizontal rod 19. The height of the height increasing plate is less than the distance between the top horizontal rods and the middle horizontal rods, and the width of the height increasing plate is less than the length of the top horizontal rod connected to the height increasing plate.
[0036] The middle horizontal rods can further reinforce the overall strength of the frame. In order to accommodate the folded height increasing plate, the size of the rectangular space surrounded by the two adjacent vertical rods, the top horizontal rods and the middle horizontal rods needs to be greater than the height and width of the height increasing plate.
[0037] Since a door body needs to be arranged on one side of the logistics trolley, the middle two horizontal rod 19 can not be arranged on the side of the door body, and the height increasing plate is not arranged at the top two horizontal rod 17 to avoid interfering with the opening and closing of the door body.
[0038] In a preferred embodiment, the flexible partition member comprises an upper partition member 21 and a lower partition member 22, the upper partition member 21 is arranged between the top cross bar and the middle cross bar, and the lower partition member 22 is arranged between the middle cross bar and the bottom plate 15.
[0039] The flexible partition member is in a split type of upper partition member 21 and lower partition member 22, so that the upper space formed by the top cross bar and the middle cross bar, and the lower space formed by the middle cross bar and the bottom plate 15 can be partitioned, and the upper partition member 21 and the lower partition member 22 can be replaced or tensioned and adjusted respectively.
[0040] In a preferred embodiment, the two ends of the flexible partition member in the transverse direction are connected between the adjacent two vertical bars, or the flexible partition member is surrounded around the outer periphery of the frame.
[0041] Similar to the vertical arrangement of the flexible partition member, in the transverse direction, the flexible partition member can be split type, i.e. one flexible partition member is arranged in each grid surrounded by the vertical bar and the cross bar, or it can be a whole, i.e. the flexible partition member is surrounded around the outer periphery of the frame and is arranged on the outer side of the frame, which can be set according to actual needs.
[0042] In a preferred embodiment, the connection between the upper partition member 21 and the top cross bar, the connection between the upper partition member 21 and the middle cross bar, the connection between the lower partition member 22 and the middle cross bar, and the connection between the lower partition member 22 and the bottom plate 15 are respectively provided with a tensioning structure.
[0043] In order to prevent the upper partition member 21 and the lower partition member 22 from being soft, the tensioning structure is arranged on the upper and lower sides of the upper partition member 21 and the lower partition member 22, so that the flexible partition member is tensioned to an appropriate degree, and the goods in the loading space are not shaken.
[0044] In a preferred embodiment, as shown in Figure 1 and 2 The tensioning structure comprises a U-shaped bolt 24 and a tensioning nut 25, a bolt fixing portion 23 is arranged on the flexible partition member, the middle part of the U-shaped bolt 24 is arranged in the bolt fixing portion 23, and the two connecting arms of the U-shaped bolt 24 are respectively fixed on the frame or the bottom plate 15 through the tensioning nut 25, the tensioning structure is quickly installed and removed, and the tensioning can be realized by adjusting the tensioning nut 25 at the two connecting arms of the U-shaped bolt 24.
[0045] In a preferred embodiment, the flexible partition is made of wear-resistant canvas material, the bolt fixing portion 23 and the flexible partition are of an integrated cutting structure which is simple in structure and convenient to process, the bolt fixing portion 23 can be a rectangle protruding from the edge of the main body of the flexible partition, the rectangle is folded inward and sewn to form the bolt fixing portion 23, the middle part of the U-shaped bolt 24 can be inserted and fixed therein, and can also be quickly disassembled; in addition, the bolt fixing portion 23 is linear tensioning, rather than point tensioning, which can more evenly tension the flexible partition.
[0046] In a preferred embodiment, the thickness of the heightening plate is less than the diameter of the vertical rod. In this way, it can be ensured that the heightening plate is located between the adjacent two vertical rods after being folded downward and does not exceed the vertical rod, without occupying additional loading space.
[0047] In a preferred embodiment, in order to prevent the goods from abutting on the heightening plate and protruding outside the frame when the goods are too much or the logistics trolley tilts when turning, and giving too much tension to the flexible partition, an angle limiting device is arranged between the heightening plate and the frame, which can prevent the heightening plate from rotating and protruding outside the frame. The angle limiting device can be a limiting strip fixedly arranged on the vertical rod and capable of extending to the folded and stored heightening plate.
