Description

TECHNICAL FIELD

[0001] The application relates to the technical field of inner supports of packaging boxes, in particular to a pearl wool inner support of a tear-resistant packaging box. BACKGROUND

[0002] The pearl wool (EPE) is full name of polyethylene foamed cotton, which is a non-crosslinking closed cell structure material. It is produced by taking low-density polyethylene (LDPE) as a main raw material and generating countless independent bubbles through physical foaming. The bubbles are uniformly distributed in the material, so that the material has many unique physical properties. The pearl wool is widely used for the packaging of electronic appliances, instruments, glass ceramics, handicrafts, medical devices and many other products.

[0003] In addition, the existing Chinese patent with the publication number CN220616719U discloses a pearl wool inner support of a tear-resistant packaging box, and specifically relates to the technical field of inner supports of packaging boxes. The inner support comprises a supporting plate and a fixing mechanism.

[0004] The above patent can support and buffer the articles through the supporting plate and the supporting spring. However, the limitation is too poor. Since the sizes and shapes of the articles assembled on the inner support are different each time, generally, a recess corresponding in shape is formed on the top of the inner support for fixation. This way greatly reduces the convenience of use of the inner support. Since the sizes of the stored articles are different from the sizes of the article storage grooves, this will cause the stored articles to shake during transportation, thereby affecting the appearance of the articles. In order to improve the convenience of use of the inner support and facilitate the fixation of the articles, the application provides a pearl wool inner support of a tear-resistant packaging box. Content of the utility model

[0005] In order to improve the problem of too poor limitation of use of the existing inner support, the application provides a pearl wool inner support of a tear-resistant packaging box.

[0006] The application provides a pearl wool inner support of a tear-resistant packaging box, which adopts the following technical scheme:

[0007] The pearl wool inner support of the tear-resistant packaging box comprises a pearl wool bottom support. A article storage groove is formed on the top of the pearl wool bottom support. Rectangular holes A and B are symmetrically formed on the bottom of the article storage groove. Rectangular grooves are symmetrically formed on the bottom of the pearl wool bottom support. A fixing belt is movably penetrated into the rectangular holes A and B. Limiting blocks A and B are respectively bonded to the two ends of the fixing belt. The limiting block A abuts against the bottom of the rectangular groove, and the limiting block B is slidingly fitted in the rectangular groove.

[0008] By adopting the above technical scheme, the fixing belt with the two ends fixed with the limiting block A and the limiting block B can be fixed in the storage groove on the top of the pearl wool bottom support under the action of the rectangular hole A and the rectangular hole B, and the size can be adjusted, thereby facilitating the fixation of different sizes of articles.

[0009] Preferably, one side of the pearl wool bottom support is bonded with a side plate A, and an insertion slot is equidistantly arranged on the outer side of the side plate A.

[0010] By adopting the above technical scheme, the insertion slot on the outer side of the side plate A can facilitate the subsequent installation of the positioning block.

[0011] Preferably, a plurality of positioning blocks for positioning are inserted into the insertion slot.

[0012] By adopting the above technical scheme, the installation of the positioning block can play a role in assisting the fixation of the internal placed article and achieving a stable effect.

[0013] Preferably, two protruding blocks are symmetrically fixed and connected below the inner side of the side plate A, the two protruding blocks are abutted in the rectangular groove, the end portions of the two protruding blocks are bonded with a limiting block C, and limiting grooves are arranged on the bottom portions of the two protruding blocks.

[0014] By adopting the above technical scheme, the protruding blocks are abutted in the rectangular groove, which can assist the installation of the side plate A, and the limiting grooves arranged on the bottom portions of the protruding blocks can play a role in limiting.

[0015] Preferably, a sliding plate is slidingly fitted in the limiting groove, one side of the sliding plate is fixedly connected with a limiting column movably penetrating the limiting block C, the end portion of the limiting column is fixedly connected with a pressing block, and the end portion of the pressing block is abutted on one side of the limiting block B.

[0016] By adopting the above technical scheme, the sliding plate is slidingly fitted in the limiting groove, which can ensure the stable movement of the sliding plate and the limiting block C, and the pressing block can control the position of the limiting block B.

[0017] Preferably, a compression spring is sleeved on the outer peripheral surface of the limiting column and abutted on the limiting block C and the pressing block at two ends.

[0018] By adopting the above technical scheme, the installation of the compression spring can enable the pressing block to move left and right, so that the limiting block B can generate a pulling force.

[0019] Preferably, a side plate B is bonded on the side of the pearl wool bottom support away from the side plate A, and a groove for inserting the positioning block is arranged on the side plate B corresponding to the insertion slot.

[0020] By adopting the above technical scheme, the groove on the outer side of the side plate B can facilitate the subsequent installation of the positioning block.

[0021] Preferably, the side plate A, the side plate B and the convex block are made of pearl wool material, the limiting block C, the limiting block A and the limiting block B are made of hard plastic, and the fixing belt is made of artificial fiber cloth.

[0022] By adopting the above technical scheme, the pearl wool material and the hard plastic are both low-value materials, and the cost can be effectively controlled.

[0023] In summary, the present application has at least one of the following beneficial technical effects:

[0024] 1. The limiting block A and the limiting block B are respectively bonded at both ends of the fixing belt, so that the fixing belt installed on the storage groove can be adjusted in length, thereby fixing different sizes of objects, improving the flexibility of the pearl wool inner support, and installing a set of tightness adjusting devices on the bottom of the pearl wool bottom support, which can be linked with the fixing belt, so that the fixing belt has the effect of adjusting the tightness, and the fixing belt can tighten the objects placed in the storage groove, avoiding the shaking of the goods during transportation, and improving the stability of the object transportation.
