[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0028] See also Figures 1-6 A double-door plastic-bottom logistics trolley includes: a back panel 1, both sides of the back panel 1 are connected to side panels 2 through multiple rotating limit frames, the side panels 2 are connected to the box door 3 through multiple limiting components, the bottom of the back panel 1 is rotatably provided with a bottom panel 5, the back panel 1 is fixedly connected to a first round rod 11, and the side of the side panel 2 close to the back panel 1 is fixedly connected to a second round rod 21, one end of the rotating limit frame is fixedly sleeved on the first round rod 11, and the other end of the rotating limit frame is movably sleeved on the outside of the second round rod 21, and a slide groove 65 is opened on the rotating limit frame, and a welding block 64 is fixedly connected to the side of the second round rod 21, and the welding block 64 is slidably set in the slide groove 65.

[0029] Specifically, as the second round rod 21 rotates in the rotation limit frame, the welding block 64 slides along the slide groove 65, so that the side panel 2 rotates relative to the back panel 1, and the side panel 2 is expanded or retracted.

[0030] The present invention realizes the folding of the trolley by rotating the limit frame, and limits the rotation range of the side panel 2 relative to the back panel 1 by setting the welding block 64 and the slide groove 65, so that the trolley is more stable when unfolded. By setting a limit component between the side panel 2 and the box door 3, the box door 3 can only rotate outward relative to the side panel 2, which facilitates the folding of the trolley and then facilitates the transportation and storage of the trolley.

[0031] Furthermore, the rotation limit frame includes a "+" sub-buckle 61 and a "+" sub-buckle 62, which are locked together by a fixing nut 63. The notches on the "+" sub-buckle 61 and the "+" sub-buckle 62 form a slide groove 65 when the two are engaged.

[0032] Specifically, four rotation limit frames are arranged at equal distances on the first round rod 11 and the second round rod 21. During installation, the "+" buckle 61 and the "+" buckle 62 clamp the first round rod 11 and the second round rod 21 therein through the fixing nut 63. The first round rod 11 is clamped and limited, while the second round rod 21 is just surrounded. However, the welding block 64 is placed in the slide groove 65, so that the rotation range of the second round rod 21 relative to the rotation limit frame is limited, that is, the side panel 2 can only rotate at most 90 degrees relative to the back panel 1. When the bottom plate 5 is stuck between the two side panels 2 and the back panel 1, the overall frame of the logistics trolley is fixed, so that the logistics trolley frame is fixed without using any locking mechanism for limiting, which greatly improves the efficiency of the logistics trolley when it is deployed or stored.

[0033] Furthermore, the limiting assembly includes a folding outer panel 41, a folding inner panel 42 and a folding shaft core 43. The folding outer panel 41 is fixedly connected to the box door 3, and the folding inner panel 42 is fixedly connected to the side panel 2. The folding outer panel 41 and the folding inner panel 42 are connected by the folding shaft core 43. The side of the side panel 2 is rotatably connected to a hook 22. A window 31 is provided on the box door 3. When the box door 3 is reversed and fits with the side panel 2, the hook 22 passes through the window 31 to hook the box door 3. The bottom of the box door 3 is fixedly connected to a bending plate 32 that cooperates with the side panel 2.

[0034] Specifically, the hinge outer panel 41, the hinge inner panel 42, and the hinge shaft core 43 are hinges in the prior art. Their specific connection method and working principle are prior art and are currently sold products. The purpose of setting four hinges between the box door 3 and the side panel 2 here is to make the box door 3 only rotate outward relative to the side panel 2 and unable to rotate toward the inside of the logistics trolley. When the box door 3 is rotated to fit tightly with the side panel 2, the window 31 opened on the box door 3 is actually the bending plate 32 that contacts the side panel 2, preventing the box door 3 from fully contacting the side panel 2. At this time, the hook 22 is rotated so that the hook 22 hooks the slot set on the box door 3, so that the box door 3 is limited to the side of the side panel 2. By setting the bending plate 32, the box door 3 is prevented from rotating in the direction close to the side panel 2, thereby avoiding the hook 22 from disengaging from the slot set on the box door 3, thereby enhancing the stability of the box door 3 being limited on the side of the side panel 2.

[0035] Furthermore, a ridge for mounting the bottom plate 5 is provided at the lower end of the inner side surface of the side plate 2 .

[0036] Specifically, when the logistics trolley is unfolded, after the two side panels 2 are rotated 90 degrees relative to the back panel 1, the bottom panel 5 connected to the back panel 1 is rotated and reversed downward, so that the bottom of the bottom panel 5 contacts the ridges provided on the side panels 2, and the bottom panel 5 is limited to the horizontal plane where the ridges are located, thereby preventing the two side panels 2 from folding inward, thereby enhancing the stability of the logistics trolley. The bottom panel 5 is provided with a slot for forklift lifting and a through hole passing through the bottom panel 5, which on the one hand facilitates the transfer of the logistics trolley by the forklift, and on the other hand prevents sewage from being trapped in the logistics trolley.

[0037] In the present invention, the logistics trolley is provided with a rotating limit frame at the connection between the side panel 2 and the back panel 1, which reduces the space utilization when folded. The unique welding assembly avoids the reversal operation and greatly reduces the difficulty of manual use. At the same time, the logistics trolley adopts a rotating structure multiple times to make the whole vehicle completely foldable, greatly reducing the footprint and making it easier to operate.

[0038] In the present invention, the two doors 3 are locked by a lock assembly, which is installed on one of the doors 3. Figure 7 and Figure 8 When the locking cam 72 is in the closed position, the locking cam 72 will be in the closed position, so the winch 72 will have a check mark on the left and right sides of the lock 74. When the winch 72 is in the closed position, the winch 72 will have a check mark on the right and the winch 74 will have a check mark on the right. The locking cam 72 is fixed to the locking cam 73 so that the locking cam 73 can be locked to the locking cam 73.

[0039] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
