[0018] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. The components of the embodiments of the present utility model usually described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0020] In the description of the embodiments of the present utility model, it should be noted that if terms such as "upper", "lower", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, or the orientations or positional relationships in which the utility model product is usually placed during use, it is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the present utility model. In addition, in the description of the present utility model, if terms such as "first", "second", etc. are only used for differential description, they cannot be construed as indicating or implying relative importance.

[0021] In the description of the embodiments of the present utility model, it should also be noted that unless otherwise clearly specified and defined, if the terms "arrangement" and "connection" are used, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0022] As shown in the attached drawings, the present utility model includes a tray rack 1. Two cross-shaped slide rails 2 are provided at the top of the tray rack 1, and two sliders 3 are slidably connected to each slide rail 2. A foldable and retractable limiting stop rod 5 is provided on each slider 3.

[0023] When in use, according to the size of the unfolded packaging box, that is, the size after cardboard printing, first place a pallet in the middle position at the top of the tray rack 1, and then stack the cardboard on the pallet in sequence. After stacking is completed, erect the limiting stop rod 5 and move it to the side of the cardboard to limit the side of the cardboard, effectively preventing the cardboard from slipping and falling during handling and transportation.

[0024] Specifically, two cross-shaped slide rail installation grooves are provided at the top of the tray rack 1, and the slide rails 2 are installed in the corresponding slide rail installation grooves.

[0025] The height of the slider 3 is not higher than the height of the slide rail installation groove. After the cardboard is stacked, the slider 3 can move freely on the slide rail 2.

[0026] Preferably, the limiting stop rod 5 is a U-shaped rod. Both ends of the opening part of the U-shaped rod are respectively hinged to the corresponding slider 3 through pin shafts. A set of positioning and locking grooves 7 that cooperate with the U-shaped rod are respectively provided on both sides of the track of the slide rail 2 along its length direction.

[0027] Both ends of the opening part of the U-shaped rod are provided with pin shaft installation long holes 8.

[0028] In the default state, the limiting stop rod 5 lies flat. When in use, rotate the limiting stop rod 5 to make it erect and move along with the slider 3 until the limiting stop rod 5 moves to the side position of the cardboard, and then insert the limiting stop rod 5 downward into the positioning and locking groove 7. At this time, the limiting stop rod 5 can maintain a vertical state. When not in use, pull out the limiting stop rod 5 from the positioning and locking groove 7 and then rotate it to make it lie flat.

[0029] Furthermore, positioning blocks 9 that cooperate with the positioning and locking grooves 7 are provided on the rear sides of the two columns of the U-shaped rod.

[0030] After the limiting stop lever 5 is laid flat, the positioning block 9 on its rear side is inserted into the positioning and locking groove 7. When moving the handling tray, the slider 3 and the limiting stop lever 5 remain fixed in position. When the limiting stop lever 5 is laid flat, its end should not extend beyond the tray rack 1.

[0031] Preferably, the tray rack 1 includes an integrally formed top panel 10, a bottom frame 11, and a group of support columns 12 connecting the top panel 10 and the bottom frame 11, and the slide rail 2 is installed on the top panel.

[0032] The handling tray in this case is made of plastic. The gap between the top panel 10 and the bottom frame 11 facilitates the positioning and handling by a forklift. The bottom frame 11 is composed of an outer frame and a cross connecting plate, and the support columns 12 are all located on the outer frame and the cross connecting plate.

[0033] In a second embodiment of the top panel 10, the top panel 10 is a grid-like hollow structure to reduce the weight of the handling tray and save materials, and the hollow parts avoid the outer frame and the cross connecting plate.

[0034] Furthermore, positioning blocks 13 protruding upward are provided on the outer sides of the four corners of the top panel 10, which facilitates the positioning and alignment when the handling trays are stacked up and down.
