[0014] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0015] See also Figure 1-Figure 4 The utility model provides a cross packaging liner, comprising a first paperboard and a second paperboard in a long strip shape, wherein the cross sections of the first paperboard and the second paperboard are in a half "mouth" shape, wherein the first paperboard comprises a first bottom plate 11 and two first side plates 12 integrally arranged on both sides of the first bottom plate 11, and the second paperboard comprises a second bottom plate 21 and two second side plates 22 integrally arranged on both sides of the second bottom plate 21; two plug-in parts 3 are arranged on one side of the two first side plates 12 facing away from the first bottom plate 11 and on one side of the two second side plates 22 facing away from the second bottom plate 21, and when the plug-in parts 3 of the first side plates 12 and the second side plates 22 are plugged into each other, the first paperboard and the second paperboard are in a cross shape; the second bottom plate 21 is provided with a storage opening 4, and the storage opening 4 is located between the two plug-in parts 3.

[0016] Through the design of the first cardboard and the second cardboard, the two pieces of cardboard are plugged into a cross structure. When transporting products such as a cross shaft or a cross electrical bridge, the second bottom plate 21 can support the product to avoid collision with the bottom during transportation. The structure between the storage port 4 and the two first side plates 12 can limit the product. For products with protruding structures on the top, the protruding structures can also be placed in the storage port 4. Compared with the general padding structure, the utility model uses less paper, is more energy-saving and environmentally friendly; and can better fit the product to avoid displacement and collision of the product during transportation.

[0017] Furthermore, the top of the first side plate 12 and the top of the second side plate 22 are folded inward to form a reinforcement portion 5 .

[0018] Through the design of the reinforcing portion 5 , the strength of the first side plate 12 and the second side plate 22 is improved to prevent the first side plate 12 and the second side plate 22 from being crushed, so that the utility model can support heavier products.

[0019] Furthermore, the left and right sides of the storage opening 4 penetrate through the two second side panels 22 , and after assembly, a limiting portion 6 is formed between the two first side panels 12 .

[0020] Through the design of the limiting portion 6, the product can be more easily embedded in the first side plate 12 and the second side plate 22, so as to better limit the position of the product and prevent the product from being displaced during transportation.

[0021] Furthermore, the first side plate 12 is recessed inwards at a position between the plug-in parts 3 and facing away from the first bottom plate 11 to form a first recessed portion 91, and the second side plate 22 is recessed inwards at a position between the plug-in parts 3 and facing away from the second bottom plate 21 to form a second recessed portion 92. Through the design of the first recessed portion 91 and the second recessed portion 92, the first paperboard and the second paperboard are more fitted and smooth as a whole after being plugged in, without protruding parts, and the structure is more stable.

[0022] Furthermore, an insert block 7 is provided on the reinforcing portion 5 , and an insert port 8 is provided on the first bottom plate 11 and the second bottom plate 21 .

[0023] Through the cooperation of the plug block 7 and the plug port 8, the reinforcing part 5 is clamped after being bent. When plugging in, the position of the reinforcing part 5 does not need to be adjusted, which facilitates assembly and makes the structure more stable after assembly.

[0024] Furthermore, at least eight plug-in ports 8 are provided, at least four are provided on the first bottom plate 11 and the second bottom plate 21 , and at least eight are provided on the plug-in blocks 7 .

[0025] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
