[0080] Example 1

[0081] Referring to FIGS. 1-19, the present embodiment provides a spring mattress packaging device and a transport vehicle for packaging and transporting a detachable spring mattress, which includes an upper cushion layer 11, an elastic module, and a bottom plate, and the three are detachable, the upper cushion layer 11 is a soft cushion layer, the elastic module is formed by detachable connection of a plurality of spring units 5, and the bottom plate is formed by detachable splicing of a plurality of bottom plate units 6; therefore, when the merchant ships or the user moves, a spring mattress can be respectively divided into an upper cushion layer 11, a plurality of spring units 5, and a plurality of bottom plate units 6 for packaging.

[0082] The spring mattress packaging device of the present embodiment is divided into a plurality of packaging containers, specifically, the packaging containers include a first packaging container 1 for packaging the upper cushion layer 11, a second packaging container 2 for packaging the spring unit 5, and a third packaging container 3 for packaging the bottom plate unit;

[0083] The upper cushion layer 11 can be folded or wound and loaded into a first packaging container 1 because it is a soft cushion layer, wherein the first packaging container 1 can adopt an elongated packaging box, and the upper cushion layer 11 is wound and loaded into the elongated packaging box, as shown in FIG. 4b; or a flat packaging box as shown in FIG. 4a, and the upper cushion layer 11 is folded and loaded into the flat packaging box, the shape and size of the first packaging container 1 are specifically selected according to the volume and size of the upper cushion layer 11, and are not particularly limited, as long as the purpose of the present application can be achieved.

[0084] In order to be able to load more spring units 5 in the second packaging container 2 and save the volume of transportation, in the present embodiment, the spring units 5 can be locked in a compressed state, and the spring units 5 locked in the compressed state are stacked in at least two second packaging containers 2.

[0085] When packaging the elastic module, all spring units 5 can be separately detached, then compressed to a locked state, and stacked in the second packaging container 2. Among them, the spring units 5 can be stacked in the second packaging container 2 in the form of N1*N2*N3, wherein N1 is greater than or equal to 1, N2 is greater than or equal to 1, and N3 is greater than or equal to 1. Specifically, the spring units 5 can be stacked in the elongated packaging box in the form of 1*10, or the spring units 5 can be stacked in the flat packaging box in the form of 2*5 or 4*5, or the spring units can be stacked in the cubic packaging box in the form of 2*5*5.

[0086] In addition, as shown in FIG. 8-10, the elastic module can be disassembled in a modular manner, directly disassembled into individual modules without splitting the individual spring units 5, and then stacked in the above-mentioned stacking manner in at least two second packaging containers 2. The bottom plate is split into the bottom plate unit 6 and stacked and installed in the two or fewer third packaging containers 3. As a simple alternative to this embodiment, the bottom plate can also be folded and packaged in the two or fewer third packaging containers 3.

[0087] The first packaging container 1, the second packaging container 2, and the third packaging container 3 are stacked with each other to form the packaging device, and the packaging device is stacked on the transport cart 7

[0088] In particular, the transport cart includes a bearing portion 71, which is a plate-shaped bottom support plate, the lower corners of which are provided with rollers 8, and the upper portion of which is provided with a handle 72 perpendicular to the bottom support plate, which is used to push the transport cart 7. The transport cart 7 also includes a strap 9 as a fixing member, which is used to tighten the packaging containers to fix them on the transport cart 7.

[0089] When the merchant ships or the user needs to move, the components of the spring mattress can be disassembled into the smallest units, then packaged in the first packaging container 1, the second packaging container 2, and the third packaging container 3 in the above-mentioned manner, and then stacked on the transport cart 7, and then tightened with the strap 9 to make the packaging containers compact and stable on the transport cart 7. When transporting, pushing the handle 72 can drive the entire transport cart to move.

[0090] Compared with the traditional packaging and transportation method, in this embodiment, when moving, smaller packaging containers can make the user move more easily, and then when transporting, the transport cart 7 can make the packaging device compact and stable, and the transport cart 7 is provided with rollers 8 and a handle 71 to make moving more convenient and labor-saving.

[0091] When the transport cart 7 is idle, it needs to occupy a certain storage space, in order to save the storage space of the transport cart, the handle 72 has a rotating degree of freedom relative to the bottom support plate, and can be rotated to be parallel to the bottom support plate, and in order to further save space, a recess 711 consistent with the shape of the handle is formed on the surface of the bottom support plate for embedding the handle 72.

[0092] In order to make it easier for the user to move the first packaging container 1, the second packaging container 2, and the third packaging container 3, the packaging containers are each provided with a handle 10, which can be used by the user to lift the packaging containers, thereby saving labor.

[0093] In order to make the first packaging container 1, the second packaging container 2, and the third packaging container 3 more compact and stable when stacked together, in the present embodiment, the packaging container surface is provided with a circular hole, wherein a boss is installed in the circular hole of the lower surface as an insertion piece, and a sunken platform is installed in the circular hole of the upper surface as an insertion matching piece, which is vertically downwardly recessed on the upper surface.

[0094] When the packaging containers are stacked along the vertical direction, the boss of the lower surface of the packaging container is inserted into the sunken platform of the lower surface, so that the adjacent upper and lower packaging containers are limited in the horizontal direction, reducing the risk of toppling when the packaging containers are stacked to a high level.

[0095] As a simple alternative of the present embodiment, as shown in FIGS. 41-42, a boss 11 that is vertically upwardly protruding can also be installed on the upper surface of the packaging container as an insertion piece, and a recess 12 that is vertically upwardly recessed can be installed in the circular hole of the lower surface of the packaging container as an insertion matching piece; the boss 11 is provided with a protrusion 111, and a flange is formed around the protrusion 111, which is tapered in width along the insertion direction; the recess 12 is provided with an opening 121 for the insertion of the protrusion 111. When stacked, the protrusion 121 is inserted into the opening of the recess, and the flange is limited by the surface of the recess, preventing the packaging containers from toppling.

[0096] Among them, the upper surface and the lower surface of the packaging container refer to the upper and lower positions of the packaging container when stacked, and the upper and lower surfaces when not stacked are based on the user's placement. The lower surface when stacked can be the upper surface when not stacked.

[0097] In the present embodiment, the bottom support plate can also be provided with the above-mentioned insertion piece or insertion matching piece for further fixing the stacked packaging containers.

[0098] As a simple alternative of the present embodiment, the first packaging container 1, the second packaging container 2, and the third packaging container 3 can be freely combined and stacked on one transport vehicle. Three kinds of packaging containers can be stacked at the same time, or any two or one kind can be stacked.

[0099] Embodiment 2

[0100] The fixing method using the strap 9 can still cause toppling during handling, so in order to further fix the packaging containers on the transport vehicle 7, referring to FIGS. 20-25, in the present embodiment, the guardrails 73 are provided around the carrying part 71 as fixing pieces to fix the packaging containers in the transport vehicle 7.

[0101] Specifically, the guardrail includes a first rail 731 parallel to the carrier portion, and a second rail 732 connected between the first rail 731 and the carrier portion 71. The first rail 731 and the second rail 732 together fix the packaging container above the carrier portion.

[0105] Referring to FIGS. 26-40, in order to enable the transport vehicle to be folded when idle, in the embodiment, the carrier portion of the transport vehicle also includes a first crossbar 712, a second crossbar 713, and a connecting rod 714, the first crossbar 712 and the second crossbar 713 are connected to form a rectangular space, the connecting rod 714 is arranged between the first crossbar 712 for carrying the packaging container, the first crossbar 712 includes a first part 7121 and a second part 7122, the first part 7121 and the second part 7122 are respectively rotatably connected with the second crossbar 713, specifically, hinged, and the first part 7121 and the second part 7122 are also hingedly connected to form the first crossbar 712.

[0106] The first rail 731 of the guardrail is divided into two fixed rods 7311 and two movable rods 7312, the two fixed rods 7311 are arranged opposite to each other, and the two movable rods 7312 are respectively rotatably connected between the end portions of the two fixed rods 7311. The movable rod is divided into two sub-movable rods 73121, the opposite ends of the two sub-movable rods 73121 are respectively rotatably connected with the end portions of the fixed rods 7311, and the opposite ends are rotatably connected.

[0107] As shown in FIG. 38, an external force is applied to the surface where the second crossbar 713 of the transport vehicle is located, the first part 7121 and the second part 7122 of the first crossbar 712 are rotated to be parallel to the second crossbar 713 and overlap each other. At the same time, the movable rod 7312 of the guardrail is also rotated to be parallel to the fixed rod 7311 and overlap each other, thereby folding the transport vehicle 7. The folded transport vehicle 7 does not occupy storage space.

[0108] In order to prevent the packing container from falling out of the side rail 73, in the embodiment, the second rail 732 of the side rail 73 is connected with the first rail 731 at both ends, and the middle sections of the adjacent second rails 732 on the same side of the bearing part 71 are respectively extended towards each other and connected together, forming an X-shaped side rail 73, so as to prevent the packing container from leaking out of the side and further stabilize the packing container.
