Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a packaging box with a built-in protection mechanism. Background Art

[0002] In modern logistics and commodity transportation, ensuring the safety of items within packaging is crucial. Traditional packaging boxes typically use simple filling materials such as foam for cushioning. During transportation and storage, items are easily damaged by external forces such as vibration, collision, and squeezing. To better protect items and improve packaging reliability and adaptability, a new type of packaging box with built-in protection is needed.

[0003] The filling materials of traditional packaging boxes often cannot fit the items completely, and there are gaps, which cannot provide comprehensive protection. When subjected to large external forces, the items are easily damaged. Items of different shapes and sizes require filling materials of different specifications, which increases the complexity and cost of packaging. Moreover, the filling materials are difficult to adapt to changes in the shape of the items, and the protection effect is unstable. It takes a lot of time to select and place the filling materials, which reduces packaging efficiency. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a packaging box with a built-in protection mechanism, which solves the problem of shaking and collision of items in the packaging box during transportation.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a packaging box with a built-in protective mechanism, comprising a box body, mounting plates fixedly installed on both sides of the inner cavity of the box body, a plurality of first springs fixedly installed on the bottom of the inner cavity of the box body, the top ends of the first springs fixedly connected to the bottom plate, the two ends of the bottom plate respectively pass through the mounting plates and extend to the inner cavity of the mounting plates, the two opposite sides of the mounting plates are provided with through grooves for use with the bottom plates, the top of one side of the box body is hingedly connected to a top cover by a hinge, the top of the bottom plate is bonded with a first buffer sponge, and the bottom of the top cover is bonded with a second buffer sponge.

[0006] The top end of the second end of the second end is fixedly provided with a first end and a second end of the second end, and the bottom end of the second end is fixedly provided with a first end and a second end of the second end.

[0007] Preferably, a second spring is fixedly connected between one side of the inner cavity of the mounting plate and the second vertical rod.

[0008] Preferably, a slot for placing items is provided on the surface of the first buffer sponge.

[0009] Preferably, a third buffer sponge is bonded to opposite sides of the two mounting plates.

[0010] Preferably, a buckle tongue is fixedly mounted on the surface of one side of the box body, and a buckle body used in conjunction with the buckle tongue is fixedly mounted on the surface of one side of the top cover.

[0011] Beneficial effects

[0012] The utility model provides a packaging box with a built-in protection mechanism. It has the following beneficial effects:

[0013] The utility model cooperates with the mounting plate, the bottom plate, the inclined portion, the first spring, the first buffer sponge, the second buffer sponge, the first inclined push block, the second inclined push block, the third inclined push block, the second spring and the article placement slot. When the top cover of the packaging box is closed, the height can be adjusted to a certain extent under the elastic force of the first spring according to the articles placed in the packaging box for adaptive fixation, so that the articles are tightly fixed in the packaging box, which greatly reduces the risk of shaking and collision of the articles during transportation. At the same time, the staff can quickly complete the packaging process without unnecessary operations, thereby improving packaging efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
