Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a packaging box capable of preventing deformation. Background Art

[0002] As the name implies, packaging boxes are boxes used to package products. They can be classified by material, such as paper boxes, iron boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated packaging boxes, PVC boxes, etc. They can also be classified by product name, such as moon cake boxes, tea boxes, wolfberry boxes, candy boxes, exquisite gift boxes, local specialty boxes, wine boxes, chocolate boxes, food, medicine and health care product boxes, food packaging boxes, gift packaging boxes, tea packaging boxes, pencil cases, etc. Functions of packaging boxes: ensure the safety of products in transportation and improve the grade of products.

[0003] The packaging box is mainly used to protect the product during transportation and carrying, and prevent the product from coming into contact with external objects and being bumped or scratched. Commonly used packaging boxes mostly adopt a split design, by opening a receiving cavity on the box body to accommodate the product, and setting a foam board in the receiving cavity on the box body for placing the product. By providing a detachable cover on the top of the box body, the objects in the box body can be easily taken in and out, and dust can be prevented from adhering to the objects in the box body.

[0004] Since the cardboard used for the box body cannot improve the overall support of the box body, when the box body carries objects for transportation, the box body is prone to sink into the box when it collides with the outside, causing the box body to deform inward, resulting in damage to the box body and inability to be reused. Utility Model Content

[0005] The utility model aims to address the defects and shortcomings of the prior art and to provide a packaging box that prevents deformation when the box body collides with the outside, which will not cause the box body to be deformed inward, and will not cause the box body to be damaged and unable to be reused.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a packaging box that prevents deformation, comprising a box body, a cover body detachably arranged on the box body, a foam board layer arranged in the box body, and also comprising a supporting frame plate arranged between the box body and the foam board layer for supporting the side walls of the box body to prevent the box body from deforming inward, a fixing piece arranged between the cover body and the box body for fixing the cover body to the box body when the cover body is installed on the box body, and a lifting device arranged on the cover body for improving the supporting performance of the supporting frame plate on the side walls of the box body when the fixing piece fixes the cover body to the box body.

[0007] A further improvement is that the support frame plate is an iron plate, a steel plate or an acrylic plate.

[0008] A further improvement is that the fixing member includes two inclined triangular blocks symmetrically arranged on both sides of the box body, two avoidance grooves respectively opened at the lower end of the cover body and located on one side of the two inclined triangular blocks, and an extrusion block arranged on the box body and located in the avoidance groove, and the upper end surface of the extrusion block is a plane.

[0009] A further improvement is that: the lower end of the extrusion block close to the inclined triangular block is provided with an inclined surface for cooperating with the inclined triangular block.

[0010] A further improvement is that the lifting device includes four through openings opened on the foam board layer, four support rods arranged on the lower end surface of the cover body and gap-matched with the through openings, the four through openings are equidistantly arranged along the rectangle of the support frame plate, and the four support rods are equidistantly arranged along the rectangle of the support frame plate.

[0011] A further improvement is that: a plurality of elastic extrusion blocks are arranged on the end surface of the support rod close to the support frame plate.

[0012] A further improvement is that: the elastic extrusion block is an arc-shaped elastic block, and the elastic extrusion block is a rubber block.

[0013] A further improvement is that a plurality of the elastic extrusion blocks are longitudinally equidistantly arranged on the support rod.

[0014] A further improvement is that the support rod is an iron rod, a steel rod or an acrylic rod.

[0015] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: when it is necessary to use a box body to carry and transport objects, the support frame plate is first placed in the box body, and the side walls of the box body can be supported by the support frame plate to prevent the box body from deforming inwardly, and then the foam board layer is placed in the support frame plate, and the foam board layer can fill the gap between the support frame plate and the box body, thereby reducing the deformation space of the support frame plate into the box body, and improving the support of the support frame plate to the box body, and the foam board layer can protect the carried object, and when the cover body is installed on the box body, the cover body is fixed to the box body by the fixing part, which can prevent the cover body from detaching from the box body and causing the object to detach, and this lifting device can improve the support of the support frame plate to the side walls of the box body, and in the process of the box body carrying objects for transportation, the box body is not easy to sink into the box when it collides with the outside, and the box body will not be deformed into the box, and the box body will not be damaged and cannot be reused.

[0016] Further effect: when the cover body is placed on the upper end of the box body for installation, as the cover body descends, the extrusion block gradually moves toward the end of the inclined triangular block, and when the extrusion block contacts the inclined triangular block, the side of the cover body located at the avoidance groove is deformed outward, and when the extrusion block moves to the lower side of the inclined triangular block, the cover body returns to its original state, so that the upper end surface of the extrusion block abuts against the lower end surface of the inclined triangular block, thereby preventing the cover body from moving upward and detaching from the box body; when the cover body needs to be removed from the box body, it is only necessary to insert a finger into the avoidance groove and pull the lower end of the cover body outward, so that the cover body is deformed outward and then lift the cover body upward, thereby removing the cover body from the box body.

[0017] Further effect: the four support rods are located at the middle end of the support frame plate. Since the support frame plate is located at the four right-angled sides of the box body with a smaller deformation, the support effect at the right angles of the box body is better, and it is not easy to deform into the box body when impacted. The middle part of the four sides around the box body has weaker support. When this part is impacted, the box body may still deform into the box. The support rods can improve the support performance of this part and reduce the phenomenon of the box body deforming into the box.

[0018] Further effect: the inclined surface can increase the contact area with the inclined triangular block when the extrusion block contacts the inclined triangular block, so that the extrusion block can be better attached to the inclined surface of the inclined triangular block.

[0027] The support frame plate 4 is an iron plate, a steel plate or an acrylic plate.

[0028] The fixing member includes two inclined triangular blocks 5 symmetrically arranged on both sides of the box body 1, two avoidance slots 6 respectively opened at the lower end of the cover body 2 and located on one side of the two inclined triangular blocks 5, and an extrusion block 7 arranged on the box body 1 and located in the avoidance slot 6, and the upper end surface of the extrusion block 7 is a plane. The inclined surface of the inclined triangular block 5 faces the end of the avoidance slot 6. The upper end surface of the avoidance slot 6 is the same as the inclined surface 8 of the inclined triangular block 5.

[0029] The lower end of the extrusion block 7 close to the inclined triangular block 5 is provided with an inclined surface 8 for cooperating with the inclined triangular block 5 .

[0030] The lifting device includes four through holes 9 formed on the foam board layer 3, and four support rods 10 provided on the lower end surface of the cover body 2 and having clearances with the through holes 9. The four through holes 9 are arranged equidistantly in a rectangular shape along the support frame plate 4, and the four support rods 10 are arranged equidistantly in a rectangular shape along the support frame plate 4. The side end surfaces of the through holes 9 are connected to the support frame plate 4.

[0031] A plurality of elastic extrusion blocks 11 are disposed on the end surface of the support rod 10 close to the support frame plate 4 .

[0032] The elastic extrusion block 11 is an arc-shaped elastic block, and the elastic extrusion block 11 is a rubber block.

[0033] A plurality of the elastic extrusion blocks 11 are longitudinally and equidistantly arranged on the support rod 10 .

[0034] The support rod 10 is an iron rod, a steel rod or an acrylic rod.

[0035] The working principle of the utility model is as follows: when the box body 1 needs to be used to carry and transport objects, the supporting frame plate 4 is first placed in the box body 1, and the side walls of the box body 1 can be supported by the supporting frame plate 4 to prevent the box body 1 from deforming inwardly, and then the foam board layer 3 is placed in the supporting frame plate 4, and the foam board layer 3 can fill the gap between the supporting frame plate 4 and the box body 1, thereby reducing the deformation space of the supporting frame plate 4 into the box body 1, improving the supporting performance of the supporting frame plate 4 to the box body 1, and the foam board layer 3 can protect the carried objects, and the cover body 2 is placed on the upper end of the box body 1 and pressed down so that the extrusion block 7 gradually moves toward the end of the inclined triangular block 5, and when the extrusion block 7 contacts the inclined triangular block 5, the side of the cover body 2 located at the avoidance groove 6 is deformed outward, and when the extrusion block 7 moves to the lower side of the inclined triangular block 5, the cover body 2 returns to its original state, so that the upper end surface of the extrusion block 7 is aligned with the lower end surface of the inclined triangular block 5. The end faces abut against each other, thereby preventing the cover body 2 from moving upward and detaching from the box body 1, and preventing the cover body 2 from detaching from the box body 1 and causing the object to detach. The four support rods 10 are located at the middle end of the support frame plate 4. Since the support frame plate 4 is located at the four right-angled sides of the box body 1, the deformation is smaller, so the support effect at the right angles of the box body 1 is better, and it is not easy to deform into the box body 1 when impacted. The middle part of the four side surfaces around the box body 1 has weaker support, and the box body 1 may still be deformed into the box when this part is impacted. The support rods 10 can improve the support performance of this part and reduce the phenomenon of the box body 1 deforming into the box. In the process of the box body 1 carrying objects for transportation, the box body 1 is not easy to sink into the box when it collides with the outside, and it will not cause the box body 1 to deform into the box, which can prevent the box body 1 from being deformed and causing the box body 1 to be damaged and unable to be reused.
