Description

Technical Field

[0001] The present invention relates to the technical field of packaging and transportation, in particular to a packaging box specially used for elevator doors. Background Art

[0002] Existing elevator doors need to be packed and placed in packaging boxes during transportation. For example, CN108974561A discloses a portable transportation box for elevator door panels. Although the box can realize the packaging and transportation of elevators, it requires a more complex structure for packaging and transportation, which greatly increases the transportation cost. After packaging and transportation, if the transportation box needs to be reused, the entire transportation box needs to be transported back to the elevator manufacturer by truck. In other words, even an empty box needs to be transported by a truck of the same load capacity, which leads to high recycling costs.

[0003] CN302639776S discloses a wooden box for packing elevator door panels. Using wooden boxes to transport elevators is also the most common packaging method at present. However, such packaging wastes a lot of manpower and material resources in the packing process (the elevator door panels need to be bundled and packed, then placed in wooden boxes, and then nailed shut). The unpacking process also wastes a lot of manpower and material resources. When unpacking, the elevator packaging box can only be disassembled by violent unpacking, which easily causes damage to the internal elevator door panels and scratches to the operators. At the same time, the wooden box packaging method cannot be recycled after disassembly and can only be disposed of as garbage. In the process of garbage disposal, the wooden boards of the wooden box need to be further cleaned and the rivets on them need to be removed, which further wastes manpower and material resources and garbage disposal costs. The wooden box packaging method is very environmentally unfriendly and does not meet the current green industry requirements of energy conservation and environmental protection in my country.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0049] like Figure 1-8 As shown, the present invention provides a packaging box specifically for elevator doors, comprising:

[0050] The base assembly 10 is of rectangular structure as a whole. A plane boss 11 capable of supporting the elevator door is formed in the middle. An annular concave support groove 12 is provided around the plane boss 11. The bottom height of the concave support groove 12 is lower than the height of the plane boss 11. Foldable side support rods 13 are respectively provided at the positions of the plane bosses 11 at both ends in the length direction of the base assembly 10. The side support rods 13 have an upright state perpendicular to the plane boss 11 and a laid-down state stored at the side of the plane boss 11. The side support rods 13 are arranged in pairs, and the tops of the two pairs of side support rods 13 in the upright state are connected by a crossbeam structure 14. In this way, a square structure is formed by the side support rods 13 on both sides and the crossbeam structure 14 on the top to limit and lock the elevator door panel from the top.

[0051] The detachable support side plate 20 is an annular structure and is connected in a surrounding manner to the concave support groove 12 of the base assembly 10; the height of the detachable support side plate 20 is higher than the height of the beam structure 14;

[0052] The buckle cover structure 30 is buckled onto the top of the detachable supporting side panel 20 .

[0053] The present invention provides a packaging box specifically for elevator doors, which can replace traditional wooden boxes for packaging elevator doors. The elevator door panels are supported by the flat boss 11 of the base assembly 10, and the elevator door panels are locked by the side support rods 13 on both sides of the special-shaped boss and the crossbeam on the top, thereby preventing the elevator door panels from moving; the elevator door panels are then packaged from the outside by the detachable supporting side panels and the buckle cover structure 30 for loading and transportation; when unloading the elevator door panels, the buckle cover structure 30 and the detachable supporting side panels can be directly removed, so that the elevator door panels will not be damaged during the disassembly process; after unloading the elevator door panels, the buckle cover structure 30 can be directly buckled on the base assembly 10, and the detachable supporting side panels can be folded and stored, thereby greatly reducing the space occupied by the entire packaging box, making it convenient for the packaging box to be recycled and reused.

[0054] The side support rods 13 are hingedly connected to the edges of the planar bosses 11, allowing them to flip and fold between horizontal and vertical planes. When flipped to a horizontal position, the loading and unloading of the elevator door panels is not affected. When flipped to a vertical position, the elevator door panels can be locked and secured from the top via a top crossbeam structure 14. The connection between the crossbeam structure 14 and the two side support rods 13 can be an adjustable structure, such as a slide groove provided on the side support rods 13, in which the crossbeam structure 14 is fixed by screws.

[0055] The side support rod 13 is connected to the base assembly 10 through a hinge, which includes a first hinge connected to the base assembly 10 and a second hinge connected to the bottom side of the side support rod 13. The first hinge and the second hinge are connected through a hinge shaft.

[0056] A support frame 15 is provided at the bottom of the planar boss 11 of the base assembly 10. A special-shaped steel beam 16 is arranged along the edge of the support frame 15 along the planar boss 11. The special-shaped steel beam 16 includes a U-shaped channel steel 161 supported at the bottom of the planar boss 11. The special-shaped steel beam 16 also includes a flange structure 162 integrally connected to the outer edge of the U-shaped channel steel 161 to form a concave support groove 12. The structural design of the special-shaped steel beam 16 allows the U-shaped channel steel 161 to provide stable support for the planar boss 11. The integrated flange structure 162 naturally forms a concave support groove 12 that accommodates the detachable support side panel 20. This ensures the structural stability of the concave support groove 12, improves the support effect, and enhances the strength of the U-shaped channel steel 161.

[0057] The flange structure 162 is also connected to the L-shaped outer flange 163, making the upper width of the concave support groove 12 larger than the lower width. This allows the cover structure 30 to be directly connected to the base assembly 10 after the detachable support side panel 20 is removed, and is restrained on all sides by the L-shaped outer flange 163. Correspondingly, the size of the L-shaped outer flange 163 is larger than the size of the cover structure 30 to accommodate it.

[0058] The bottom of the support frame 15 is connected to support feet 17 . The support feet 17 are arranged in pairs on both sides of the support frame 15 , and the number of the support feet 17 is four or more.

[0059] The two supporting feet 17 arranged in pairs are laterally connected by a bottom beam 18 .

[0060] The buckle cover structure 30 includes a top plate 31 and a frame 32 . The frame 32 is connected to the four edges of the top plate, and a receiving groove with an opening facing downward is provided at the lower portion of the frame 32 .

[0061] The frame 32 is made of a special-shaped steel member, which also forms a horizontally open transverse groove, and the top plate is inserted into the transverse groove.

[0062] The special-shaped steel component adopts an integrally formed structure.

[0063] Combine Figure 9-13The detachable supporting side panel 20 comprises a closed annular structure formed by connecting end panels 1 at both ends and at least one group of folding panels 2 between the two end panels 1. The folding panel 2 is formed by connecting two folding portions 21 of similar or equal size. The connection portion of the two folding portions 21 forms a fold 22 parallel to the end panel 1. The length of the folding portion 21 exceeds 0.8 times the length of the end panel 1 (to make the length of the folding portion as long as possible; if it is less than 0.5 times, it can be folded in an accordion manner, but this will greatly reduce the strength of the folding panel), but is less than the length of the end panel 1 (the purpose is to After folding, the two ends of the folding part do not exceed the two ends of the end plate); the folding plate 2 and the end plate 1 are connected by a folding structure 3 that can be bent 180 degrees. The middle part of the folding structure 3 is an isosceles right triangle, and the hypotenuse of the isosceles right triangle is located on the outer side. The edges of the end plate 1 and the folding plate 2 on both sides of the isosceles right triangle are respectively set to 45-degree inclined surfaces. Through the folding structure 3 of the isosceles right triangle, a 180-degree fold can be formed between the folding plate 2 and the end plate 1, thereby overcoming the thickness problem of the folding plate 2 and the end plate 1 (which usually causes the folding fold to be uneven or unable to achieve a 180-degree fold).

[0064] The fold line 22 between the two folded portions 21 of the folding plate 2 is located on the outer side of the folding plate 2 .

[0065] The inner side surface of the fold 22 is set to be a 45-degree inclined surface, and the inclined surfaces on both sides form a 90-degree right angle after the folding plate 2 is unfolded.

[0066] The two folding parts 21 of the folding plate 2 are also connected by the folding structure 3. In this way, the folding plate 2 can better adapt to bending deformation during the Z-shaped folding process, making folding and storage simpler and easier.

[0067] When the portable folding box side panels are folded, the folding panels 2 are folded in a Z-shape between the two end panels 1, and the two end panels 1 are located on the outside and parallel to each other.

[0068] The end plate 1 and the folding plate 2 are made of plastic plates with a hollow structure, and a honeycomb filling layer is arranged in the middle.

[0069] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
