Description

Technical Field

[0001] This utility model relates to the field of moisture-proof cardboard box technology, specifically to an inner lining structure for a moisture-proof cardboard box. Background Technology

[0002] Moisture-proof cardboard boxes prevent moisture from entering the box by installing moisture-proof covers at the top and bottom of the box body. The inside of the moisture-proof cardboard box is lined to protect the items.

[0003] The existing moisture-proof cardboard box lining structure has the problem that the bracket and the fixing structure are not easy to separate and fix.

[0004] The reason for this problem is that in the use of moisture-proof cardboard box lining structures, goods need to be placed inside the lining structure. To increase the protective effect of the lining structure on the goods, the cardboard structures of the lining structure are usually glued together. Therefore, when using different goods with moisture-proof cardboard boxes, all the inner cardboard needs to be replaced, resulting in waste of cardboard. If the inner cardboard is not fixed together, the protective and supportive effect on the goods will be reduced. At the same time, in order to increase the fixation effect of the lining, the lining structure is usually glued to the inside of the moisture-proof cardboard box, which makes it difficult to remove the lining structure later, affecting the reuse of the moisture-proof cardboard box and resulting in waste of cardboard box structure. Therefore, we propose a moisture-proof cardboard box lining structure. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model proposes an inner lining structure for a moisture-proof cardboard box, which solves the problem that the bracket and the fixing structure of the existing moisture-proof cardboard box inner lining structure are not easy to separate and fix.

[0006] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows: a lining structure for a moisture-proof cardboard box, comprising a cardboard box body, a moisture-proof cover plate provided on the outside of the cardboard box body, and an inner lining mechanism provided inside the cardboard box body. The inner lining mechanism includes an inner lining frame, which is movably inserted into the inside of the cardboard box body. The inner lining frame is used to increase the internal pressure resistance of the cardboard box body. A lower support frame is movably disposed inside the inner lining frame. The lower support frame is used to fix items. An adjusting cardboard is movably disposed inside the inner lining frame. The adjusting cardboard is used to increase the protective effect of the items.

[0007] Preferably, a lower fixing paper block is fixedly connected to the outside of the lower bracket, and the lower fixing paper block is disposed on the inner side of the inner liner frame.

[0008] Preferably, the upper surface of the lower bracket is provided with a socket plate, which is movably inserted into the interior of the inner liner.

[0009] Preferably, the upper surface of the socket plate is provided with an upper bracket, and an upper fixing paper block is fixedly connected to the outside of the upper bracket.

[0010] Preferably, a fixing plate is fixedly connected to the inner side of the socket plate, and a plug-in block is movably inserted into the inside of the fixing plate, and the adjusting cardboard is fixedly connected to the outside of the plug-in block.

[0011] Preferably, the exterior of the carton body is provided with a carton cover, which is located inside a moisture-proof cover.

[0012] The beneficial effects of this utility model are:

[0013] The technical solution of this utility model involves placing an inner liner frame inside the main body of the carton, then placing a lower support frame in the middle of the inner liner frame, and placing the item in the middle recess of the lower support frame. The position of the adjusting cardboard is then adjusted to create a bend, causing the adjusting cardboard to abut against the outside of the item. Inserting a connecting block into the groove inside the fixing plate reduces pressure on the item. Finally, an upper support frame is placed over the item. The inner liner frame supports and protects the four sides of the carton's interior. Different upper and lower support frames corresponding to different items are installed inside the inner liner frame. Changing the lower and upper support frames allows the carton to accommodate different items. Adjusting the cardboard further protects the exterior of different goods, thus separating the fixing and supporting structures without affecting the protective effect on different items.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. 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.

[0022] This application provides an inner lining structure for moisture-proof cardboard boxes, which solves the problem that the bracket and fixing structure of existing moisture-proof cardboard box inner lining structures are not easy to separate and fix.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] According to the appendix Figure 1-5 As shown, the carton includes a main body 1, with a moisture-proof cover 101 on the outside and an inner lining mechanism inside. The inner lining mechanism includes an inner lining frame 2, which is movably inserted into the inside of the carton body 1. The inner lining frame 2 is used to increase the internal pressure resistance of the carton body 1. A lower support frame 206 is movably disposed inside the inner lining frame 2 and is used to fix items. An adjusting cardboard 201 is movably disposed inside the inner lining frame 2 and is used to increase the protective effect of the items.

[0025] The lower bracket 206 is externally fixedly connected to a lower fixing paper block 207, which is located inside the inner liner 2. The upper surface of the lower bracket 206 is provided with a socket plate 202, which is movably inserted into the inner liner 2. The upper surface of the socket plate 202 is provided with an upper bracket 205, the upper bracket 205 is externally fixedly connected to an upper fixing paper block 208, the inner side of the socket plate 202 is fixedly connected to a fixing plate 203, and the fixed plate 203 is movably inserted into the inner side of the fixing plate 203. The adjusting cardboard 201 is fixedly connected to the outside of the inserting block 204. The outer side of the carton body 1 is provided with a carton cover plate 102, which is located inside the moisture-proof cover plate 101.

[0026] By placing the inner liner 2 inside the carton body 1, and then placing the lower support 206 in the middle of the inner liner 2, and placing the item in the middle recess of the lower support 206, the lower fixing block 207 will be located inside the inner liner 2. The lower fixing block 207 increases the compressive strength of the lower support 206 and also enhances the protection of the item. Then, the two sets of insert blocks 204 are moved to change the position of the adjusting cardboard 201 and create a bend, so that the adjusting cardboard 201 abuts against the outside of the item. Then, the insert blocks 204 are inserted into the groove inside the fixing plate 203, thereby reducing the pressure on the item when the carton body 1 is collided and squeezed. Finally, the upper support 205 is placed on top of the item. The bracket 205 will also slide inside the inner liner 2. Then, the carton cover 102 will be folded over and placed on top of the upper bracket 205. Finally, the moisture-proof cover 101 will be placed on the outside of the carton body 1. If other items need to be packaged later, the upper bracket 205 and lower bracket 206 corresponding to the item can be installed in the middle of the inner liner 2. By setting the inner liner 2 to support and protect the four sides of the carton, and installing the upper bracket 205 and lower bracket 206 corresponding to different items inside the inner liner 2, the carton body 1 can be adapted to the storage of different items. The adjustable cardboard 201 is used to further protect the outside of different goods. Thus, while separating the fixing and supporting structures, the protective effect on different items is not affected, and the operation is simple.

[0027] In summary, compared with existing technologies, it has the following beneficial effects:

[0028] By placing the inner liner 2 inside the carton body 1, then placing the lower bracket 206 in the middle of the inner liner 2, and placing the item in the middle recess of the lower bracket 206, the position of the adjusting cardboard 201 is changed to create a bend, so that the adjusting cardboard 201 abuts against the outside of the item. The insert block 204 is inserted into the groove inside the fixing plate 203 to reduce the pressure on the item. Finally, the upper bracket 205 is placed on top of the item. The inner liner 2 supports and protects the four sides of the carton's internal structure. The upper bracket 205 and lower bracket 206 corresponding to different items are installed inside the inner liner 2. By changing the lower bracket 206 and upper bracket 205, the carton body 1 can be adapted to store different items. The adjusting cardboard 201 is used to further protect the outside of different goods, so that the protective effect on different items is not affected while the fixing and supporting structures are separated.
