Detailed Implementation

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1-11 As shown, one embodiment of this utility model provides a bottom support assembly for heavy-duty oven packaging, including a bottom support paper card 1, a bottom support paper card 2, and an inner insert card 3; the bottom support paper card 1 is folded to form a box shape, and the top of the bottom support paper card 1 has an opening; The bottom support paper card 2 is folded to form a first bottom support paper tube 201 and a second bottom support paper tube 202. The first bottom support paper tube 201 and the second bottom support paper tube 202 are parallel. Both the first bottom support paper tube 201 and the second bottom support paper tube 202 are wrapped with multiple inner plug cards 3. The bottom support paper card 2 is placed on the inner bottom wall of the bottom support paper card 1, and a U-shaped space for accommodating the frame is formed between the bottom support paper card 2 and the four side walls of the bottom support paper card 1. The frame falls into the U-shaped space, and the four sides of the frame fit into the four side walls of the bottom layer that support the paper card 1.

[0022] In this embodiment, when assembling the bottom support assembly for the heavy-duty oven packaging, the bottom supporting paper card 1 is first folded and assembled as follows: Figure 1 The box-shaped structure shown has an opening at the top of the bottom supporting paper card 1 and an internal carrying space. Multiple inner insert cards 3 are then placed on the bottom support paper card 2, and the bottom support paper card 2 is folded to form a first bottom paper tube 201 and a second bottom paper tube 202, with the internal spaces of both the first and second bottom paper tubes 201 and 202 filled with inner insert cards 3. The assembled bottom support paper card 2 is then arranged according to... Figure 3 Place the card into the designated position within the bottom support card 1 as shown. At this point, a U-shaped space for accommodating the frame is formed between the bottom support card 2 and the four side walls of the bottom support card 1. Then press... Figure 6 Insert the frame into the U-shaped space. Finally, place the bottom support assembly into the packaging box and place the oven body 12 on the bottom support assembly.

[0023] Compared to traditional wooden support beams, the bottom support assembly for this heavy-duty oven packaging has at least the following advantages: First, the bottom support components for the heavy-duty oven packaging are made entirely of paper, which is lightweight and cheaper than wood, meeting green assurance requirements.

[0024] Secondly, the bottom support component for heavy-duty oven packaging can accommodate the vehicle frame, making reasonable use of the remaining space of the bottom layer supporting the paper card 1, resulting in high space utilization.

[0025] In this embodiment, as Figure 2 As shown, the bottom support paper card 2 is a thickened cardboard with high thickness and strength. In addition, inner plugs 3 are rolled into both the first bottom support paper tube 201 and the second bottom support paper tube 202 to improve the load-bearing capacity of the first bottom support paper tube 201 and the second bottom support paper tube 202.

[0026] It should be noted that when assembling the inner insert card 3, the inner insert card 3 is first placed in the designated position of the bottom support paper card 1 before folding, and then the two sides of the bottom support paper card 1 are folded around the inner insert card 3 to form the first bottom support paper tube 201 and the second bottom support paper tube 202. At this time, the inner insert card 3 is wrapped inside the first bottom support paper tube 201 and the second bottom support paper tube 202.

[0027] like Figure 1As shown, two first limiting pieces 101 and two second limiting pieces 102 are installed on the inner bottom wall of the bottom layer carrying paper card 1. The two first limiting pieces 101 are arranged along a first direction, and the two second limiting pieces 102 are arranged along a first direction. The first limiting pieces 101 and the second limiting pieces 102 correspond one-to-one, and the first limiting pieces 101 and their corresponding second limiting pieces 102 are arranged along a second direction. The first direction and the second direction are perpendicular to each other.

[0028] More specifically, the two first limiting pieces 101 and the two second limiting pieces 102 are located at the four corners of the same rectangle.

[0029] It should be noted that the first and second directions mentioned above are the side length directions of the two sides perpendicular to the bottom supporting paper card 1.

[0030] Furthermore, such as Figure 2 As shown, two rectangular inlets 203 are respectively provided at the bottom of the first bottom paper tube 201 and the second bottom paper tube 202. Correspondingly, two through holes 301 are arranged along the length of the bottom of the inner insert 3, corresponding one-to-one with the rectangular inlets 203. When the inner insert 3 is rolled into the bottom paper tube, the through holes 301 of the inner insert 3 are aligned with the rectangular inlets 203 of the bottom paper tube.

[0031] The purpose of this design is to facilitate the positioning of the base support paper card 2. Specifically, when installing the base support paper card 2 onto the bottom support paper card 1, simply align the four rectangular slots 203 on the base support paper card 2 with the four limiting pieces on the bottom support paper card 1, then lower the base support paper card 2. The two first limiting pieces 101 will insert into the rectangular slots 203 of the first base paper tube 201, and the two second limiting pieces 102 will insert into the rectangular slots 203 of the second base paper tube 202. This allows for quick positioning of the base support paper card 2, facilitating subsequent frame installation.

[0032] As an alternative embodiment, the distance between the first limiting piece 101 and the second limiting piece 102 is slightly smaller than the distance between the left side of the first bottom paper tube 201 and the right side of the second bottom paper tube 202, and the length of the two limiting pieces is greater than the width of the rectangular insertion port 203.

[0033] Thus, when placing the base support card 2, firstly, the base support card 2 is placed into the rectangular area formed by the two first limiting pieces 101 and the two second limiting pieces 102. At this time, the two first limiting pieces 101 are in contact with the left side of the first base paper tube 201, and the two second limiting pieces 102 are in contact with the right side of the two second base paper tubes 202. That is, the base support card 2 is confined between the first limiting pieces 101 and the second limiting pieces 102. Then, the base support card 2 is pushed so that the two rectangular slots 2 on the first base paper tube 201 are... 03. Align the two first limiting pieces 101. Simultaneously, the two rectangular slots 203 on the second bottom paper tube 202 will also align with the two second limiting pieces 102. Since the length of the limiting piece is greater than the width of the rectangular slot 203, the first limiting piece 101 remains in contact with the left side of the first bottom paper tube 201 and will not enter the rectangular slot 203 of the first bottom paper tube 201. Similarly, the second limiting piece 102 remains in contact with the right side of the second bottom paper tube 202 and will not enter the rectangular slot 203 of the second bottom paper tube 202. This achieves both rapid positioning of the bottom support paper card 2 and fixation of the bottom support paper card 2, preventing the bottom support paper card 2 from moving along the arrangement direction from the first limiting piece 101 to the second limiting piece 102.

[0034] In this embodiment, in order to further limit the positioning of the bottom support for the paper card 2, such as... Figure 1 As shown, a card block 103 is installed on the inner bottom wall of the bottom layer that carries the paper card 1. The card block 103 is located within the rectangular area enclosed by the first limiting piece 101 and the second limiting piece 102, and the distance between the card block 103 and any of the first limiting pieces 101 is equal to the distance between the card block 103 and any of the second limiting pieces 102. Figure 2 As shown, a positioning hole 204 is provided on the cardboard of the bottom support paper card 2 located between the first bottom support paper tube 201 and the second bottom support paper tube 202. The positioning hole 204 matches the shape of the card block 103 mentioned above, and the thickness of the card block 103 is greater than the thickness of the bottom support paper card 2.

[0035] When placing the base support card 2, align the positioning hole 204 on the base support card 2 with the locking block 103 on the bottom support card 1, then press down on the base support card 2 so that the locking block 103 on the bottom support card 1 passes through the positioning hole 204 on the base support card 2. This allows for quick and easy location of the installation position of the base support card 2, and the locking block 103 also helps to prevent the base support card 2 from shaking or shifting.

[0036] For ease of description, such as Figure 3As shown, the four sides of the base support paper card 2 are named first side 109, second side 110, third side 111, and fourth side 112, respectively. The base support paper card 2 is arranged along the side length extension direction of the second side 110, that is, the length direction of the base support paper card 2 is the same as the side length direction of the second side 110.

[0037] Press the bottom support card 2. Figure 3 After being installed into the bottom support paper card 1, the bottom support paper card 2 has a first accommodating space 105 between itself and the inner wall of the first side 109, a second accommodating space 106 between itself and the inner wall of the second side 110, a third accommodating space 107 between itself and the inner wall of the third side 111, and a fourth accommodating space 108 between itself and the inner wall of the fourth side 112. The width of the first accommodating space 105 is smaller than the width of the third accommodating space 107, while the widths of the second and fourth accommodating spaces 106 and 108 are approximately the same. The first, second, third, and fourth accommodating spaces 105, 106, 107, and 108 roughly form a U-shaped space.

[0038] like Figure 4 As shown, accessory box 4 is placed within the third accommodating space 107, with the length of accessory box 4 aligned with the length of the third side 111. At this point, there is a sufficient gap between accessory box 4 and the inner wall of the third side 111 to accommodate the vehicle frame. This optimizes space allocation within a limited area to maximize the storage of accessory box 4. It should be noted that accessory box 4 contains small oven parts such as casters, knobs, and flame distribution plates, which will be needed during actual installation.

[0039] To prevent accessory box 4 from moving, such as Figure 3 As shown, two third limiting pieces 104 are provided on the inner bottom wall of the bottom layer that supports the paper card 1 and are located in the third receiving space 107. These two third limiting pieces 104 are arranged along the side length direction of the third side 111. In this way, the accessory box 4 can be placed between the two third limiting pieces 104, and the two third limiting pieces 104 serve to limit the accessory box 4.

[0040] It should be noted that when the accessory box 4 is placed between the two third limiting pieces 104, a gap is formed between the accessory box 4 and the inner wall of the third side 111 of the bottom supporting paper card 1, and this gap is just enough to accommodate one side of the frame to be inserted.

[0041] It should be noted that the heavy-duty oven to be packaged is equipped with two frames. For ease of description, the two frames are named First Frame 5 and Second Frame 6. First Frame 5 and Second Frame 6 are arranged in a U-shape.

[0042] In this embodiment, when packing two frames, the second frame 6 can be placed inside the bottom support cardboard 1 first. At this time, the first edge of the second frame 6 is embedded in the first receiving space 105 between the bottom support cardboard 2 and the first edge 109 of the bottom support cardboard 1, and the third edge of the second frame 6 is embedded in the gap formed between the accessory box 4 and the inner wall of the third edge 111 of the bottom support cardboard 1. The second and fourth edges of the second frame 6 fall into the second receiving space 106 and the fourth receiving space 108 respectively, and the second and fourth edges of the second frame 6 are respectively in contact with the inner walls of the second edge 110 and the fourth edge 112 of the bottom support cardboard 1. Then, a frame divider 7 is placed on the top of each of the two opposite sides of the second frame 6, and finally the first frame 5 is placed on the second frame 6, thus achieving the desired result. Figure 6 The state shown.

[0043] This arrangement of the first frame 5 and the second frame 6 prevents them from wobbling and makes efficient use of the limited space. The frame partition 7 is designed to prevent the second frame 6 and the first frame 5 from scratching each other, thus protecting both frames.

[0044] As can be seen, in addition to supporting the oven body 12, the bottom support component in this embodiment can also store two frames and accessory boxes 4 in a limited space. This way, the two frames and accessory boxes 4 do not need to be stored and packed separately, resulting in high space utilization.

[0045] It should be noted that, as Figure 1 As shown, two grooves 302 are provided on the top of the inner insert card 3, and the tops of the corresponding first bottom paper tube 201 and second bottom paper tube 202 are provided with recesses that match the shape of the grooves 302. The grooves 302 on the top of the inner insert card 3 have slopes that are adapted to the bottom of the furnace body.

[0046] In this way, when the bottom of the oven body 12 acts on the two bottom support paper tubes, the front and rear inclined surfaces of the bottom of the oven body 12 fit into the inclined surface of the groove 302, which can more effectively stabilize the oven body 12 and limit the oven body after it is placed on the bottom support paper card 2.

[0047] To avoid scratches between the frame and the bottom of the oven body 12, in this embodiment, as follows: Figure 7 As shown, it also includes frame protection card 1 8, frame protection card 2 9, frame protection card 3 10 and partition card 11, wherein frame protection card 1 8 and frame protection card 3 10 are completely identical.

[0048] Among them, such as Figure 10As shown, the frame protection clip 29 is folded to form a square tube 901 and a top plate 902 located on top of the square tube 901, wherein the width of the top plate 902 is greater than the width of the square tube 901. Figure 8 As shown, after the frame protection card 29 is placed, the bottom surface of the square tube 901 of the frame protection card 29 rests on the top surface of the first bottom support paper tube 201 and the second bottom support paper tube 202, while the top plate 902 of the frame protection card 9 covers the top surface of the first frame 5, thereby protecting the top surface of one side of the first frame 5.

[0049] Furthermore, frame protection clip 1 (8) and frame protection clip 2 (9) are folded into shape, as follows: Figure 7 and Figure 11 As shown, both the front ends of frame protection clip 1 (8) and frame protection clip 2 (9) have a beveled surface 801, and the rear ends of both have a horizontal surface 802. Figure 8 As shown, when the frame protection card 1 8 and the frame protection card 2 9 are placed on the frame, the horizontal surfaces 802 of the frame protection card 1 8 and the frame protection card 2 9 cover the top surface of the first frame 5, and the inclined surfaces 801 of the frame protection card 1 8 and the frame protection card 2 9 face the bottom support paper card 2.

[0050] It should be noted that, as Figure 8 As shown, the frame protection clip 8 and the frame protection clip 9 mainly serve the following functions: First, they cover the frame, separating the bottom of the oven from the frame and preventing scratches. Second, the inclined surfaces 801 of the frame protection clips 8 and 9 are used to fit onto the inclined surfaces on the left and right sides of the bottom of the oven body 12 to support the oven body 12. Third, the inclined surfaces 801 of the frame protection clips 8 and 9, working together, also restrict the movement of the oven body 12.

[0051] In some embodiments, such as Figure 1 As shown, an insert card 113 is cut out on each of the two left sides of the bottom-layer paper card 1, as follows. Figure 7 and Figure 8 As shown, frame protection clip 8 and frame protection clip 10 are respectively provided with slots for inserting clips 113. After frame protection clips 8 and 10 are attached to the frame, clips 113 can be bent so that the clips 113 on both sides are inserted into the slots on frame protection clips 8 and 10 respectively. This helps to stabilize frame protection clips 8 and 10.

[0052] In this embodiment, as Figure 7 As shown, the divider 11 is formed by folding a rectangular card once, and includes a first plate and a second plate, with an obtuse angle between the first plate and the second plate. Figure 8 As shown, the first plate of the partition 11 covers the accessory box 4, and the bottom of its second plate rests on the inner bottom wall of the bottom paper card 1. The function of the partition 11 is to separate the accessory box 4 from the oven body 12, providing a certain buffering effect.

[0053] In summary, when assembling the bottom support components, first fold and assemble the bottom supporting paper card 1 as follows: Figure 1 As shown in the box shape, multiple inner insert cards 3 are placed on the bottom support card 2, and then the bottom support card 2 is folded to form a first bottom support paper tube 201 and a second bottom support paper tube 202, with the internal spaces of both the first bottom support paper tube 201 and the second bottom support paper tube 202 filled with inner insert cards 3. Then, the assembled bottom support card 2 is arranged according to... Figure 3 The card block 103 is placed in the designated position within the bottom support paper card 1, so that it is inserted into the positioning hole 204 of the bottom support paper card 2. At the same time, the first limiting piece 101 and the second limiting piece 102 are respectively inserted into the rectangular insertion holes 203 of the first bottom support paper tube 201 and the second bottom support paper tube 202.

[0054] Next, as Figure 4 As shown, place accessory box 4 between the two third limiting pieces 104.

[0055] Then the second frame 6 is placed in the U-shaped space. At this time, the first frame of the second frame 6 is embedded in the first receiving space 105 between the bottom support card 2 and the first side 109 of the bottom support card 1. The third frame of the second frame 6 is embedded in the gap formed between the accessory box 4 and the inner wall of the third side 111 of the bottom support card 1. The second frame and the fourth frame of the second frame 6 fall into the second receiving space 106 and the fourth receiving space 108 respectively. The second frame and the fourth frame of the second frame 6 are respectively attached to the inner wall of the second side 110 and the inner wall of the fourth side 112 of the bottom support card 1.

[0056] Next, place a frame spacer 7 on each of the two opposite top sides of the second frame 6, and finally place the first frame 5 onto the second frame 6 to achieve the desired result. Figure 6 The state shown.

[0057] Then, install frame protection clip 1 (8), frame protection clip 2 (9), frame protection clip 3 (10), and partition clip 11 according to... Figure 8 Place them in the corresponding positions as shown.

[0058] After assembling the bottom support assembly, place the bottom support assembly into the carton, then hoist the oven body 12 onto the bottom support assembly, and finally seal the carton with tape or adhesive tape.

[0059] It is evident that this bottom support assembly has the following advantages compared to wooden support beams: First, the bottom support components for the heavy-duty oven packaging are made entirely of paper, which is lightweight and cheaper than wood, meeting green assurance requirements.

[0060] Secondly, in addition to supporting the oven body 12, it can also store two frames and accessory boxes 4 in a limited space, so that the two frames and accessory boxes 4 do not need to be stored and packed separately, thus making high space utilization.

[0061] Third, the three frame protection clips cover the frame, which serves to separate the bottom of the oven from the frame and prevent scratches. In addition, the inclined surfaces 801 of the frame protection clip 1 8 and the frame protection clip 2 9 are attached to the inclined surfaces on the left and right sides of the bottom of the oven body 12 to support the oven body 12 and restrict its movement.
