Technical Field
[0001] The utility model is applicable to the technical field of cartons, and particularly relates to a carton with a moisture-proof bottom. Background Art
[0002] At present, cartons are the most widely used packaging products. Depending on the materials used, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. However, due to the limitations of the paper material itself, when the cartons are placed on the ground, the moisture conducted and penetrated by the ground will corrode the cartons and cause them to be damaged and broken. Therefore, cartons with a certain moisture-proof ability will be used for use in special environments.
[0003] However, the cartons with moisture-proof structures used nowadays often have corresponding waterproof layers between their bottom and the ground to prevent moisture from the ground from damaging the cartons when placed on the ground. In this process, cartons with a relatively simple structure and function cannot always keep contact with the bottom of the carton, which can easily cause shaking during transportation and movement, causing the bottom of the carton to separate from the waterproof board surface and affect the moisture-proof quality. Therefore, we propose a carton with moisture-proof bottom. Utility Model Content
[0004] The main purpose of the utility model is to provide a paper box with a moisture-proof bottom, which can effectively solve the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A bottom moisture-proof carton, comprising a box body, box covers are rotatably mounted on both sides of the top of the box body, and a protective frame is movably sleeved on the outer side of the bottom of the box body;
[0007] Both ends of the bottom of the outer side of the box body are fixedly installed with installation frames, and the installation frames are slidably inserted into the protection frame. Both sides of each installation frame are fixedly installed with installation plates. A movable rod is slidably installed through the inside of each side of the installation plate. A transmission block is fixedly installed on the top surface of the side of each movable rod. An adjusting bolt is screwed through the middle end of one side of each installation frame away from the box body through a thread, and a pushing block is rotatably installed on the top of the side of each adjusting bolt through a bearing.
[0008] A return spring is movably sleeved on the outer side of each movable rod, and the return spring is located between the transmission block and the mounting plate. An insertion block is fixedly mounted on the outer side surface of each movable rod at one end away from the transmission block.
[0009] By adopting the above technical solution, through the interaction between the pushing block and the transmission block, and under the pushing action of the reset spring, the operator only needs to twist the adjusting bolt to allow the movable rod to drive the insertion block to move synchronously outward to the plug-in slot at the corresponding position, thereby completing the installation and reinforcement of the box body and the protective frame, reducing the labor consumption required for the operator to install it, and ensuring that the box body will not be arbitrarily moved out of the protective frame and affect the waterproof and moisture-proof quality of the protective frame to the bottom of the box body.
[0010] As an optional solution of the technical solution of the present application, limiting grooves are provided inside both ends of the side of the protective frame, and the mounting frame is slidably inserted into the limiting grooves. Insertion grooves are provided inside the side of the protective frame, and the insertion grooves and the insertion blocks are at the same horizontal position.
[0011] By adopting the above technical solution, the positions of the plug-in slot and the insertion block are set to ensure that the plug-in slot can perform a stop-motion processing on the insertion block.
[0012] As an optional solution of the technical solution of the present application, a guide groove is opened inside the side of each mounting plate, and the movable rod passes through and is slidably inserted into the guide groove.
[0013] By adopting the above technical solution, the rationality of the movement of the entire device is ensured by the guiding sliding action of the guide groove on the movable rod.
[0014] As an optional solution of the technical solution of the present application, each of the two ends of the side of the installation frame is provided with a storage groove, and the insertion block is located inside the storage groove.
[0015] By adopting the above technical solution, the storage groove acts on the storage structure of the insertion block to ensure that the installation frame can be slidably installed inside the limiting groove, so that the insertion block will not hinder the installation of the box body.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] 1. The technical solution of the present application is a cardboard box with a moisture-proof bottom. A protective frame made of waterproof material is sleeved on the bottom of the box, and corresponding insertion grooves are arranged on the sides of the protective frame. When the bottom of the box is waterproofed, the operator only needs to twist the adjusting bolt to drive the pushing block to move horizontally inside the installation frame. When the pushing block moves, the inclined surfaces on both sides contact the inclined surfaces of the transmission block and convert the horizontal movement force into an outward pushing force on the movable rod. The movable rod can drive the insertion block to move synchronously outward to the plug-in slot at the corresponding position. Combined with the limiting effect of the plug-in slot on the insertion block, the installation and reinforcement of the box and the protective frame can be completed, reducing the labor consumption required for the operator to install it, and ensuring that the box will not be arbitrarily moved out of the protective frame to affect the waterproof and moisture-proof quality of the bottom of the box.
[0018] 2. The technical solution of the present application is a cardboard box with a moisture-proof bottom. A pushing spring is sleeved on the surface of a movable rod, so that after the movable rod moves under the interaction of a pushing block and a transmission block, the pushing spring can be deformed and can subsequently provide the driving force required for restoring the position of the movable rod, thereby ensuring that when it is necessary to disassemble and separate the box body and the protective frame, the insertion block can be automatically moved out of the plug-in slot to facilitate the separation of the box body and the protective frame, thereby improving the repeatability of the protective frame.

[0023] like Figure 1-3 As shown, the utility model provides a technical solution: a carton with a moisture-proof bottom, a protective frame 12 is movably sleeved on the outer side of the bottom of the box body 1, limiting grooves 3 are provided inside the two ends of the side of the protective frame 12, and the installation frame 2 is slidably inserted into the limiting groove 3, and the side of the protective frame 12 is provided with plug-in grooves 28, and the plug-in grooves 28 and the insertion block 27 are at the same horizontal position.
[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), mounting frames 2 are fixedly installed at both ends of the outer bottom of the box body 1, and the mounting frames 2 are slidably inserted into the protective frame, mounting plates 23 are fixedly installed on both sides of each mounting frame 2, and a movable rod 24 is slidably installed inside the side of each mounting plate 23, and a transmission block 25 is fixedly installed on the top surface of the side of each movable rod 24. An adjusting bolt 21 is screwed through a thread on the middle end of a side of each mounting frame 2 away from the box body 1, and a pushing block 22 is rotatably installed on the top of the side of each adjusting bolt 21 through a bearing.
[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), each mounting plate 23 has a guide groove 4 on its side, and the movable rod 24 is inserted into the guide groove 4 for sliding. Each mounting frame 2 has a receiving groove 31 on both ends of its side, and the insertion block 27 is located inside the receiving groove 31.
[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a return spring 26 is movably sleeved on the outer side of each movable rod 24, and the return spring 26 is located between the transmission block 25 and the mounting plate 23. An insertion block 27 is fixedly mounted on the outer side of each movable rod 24 at one end away from the transmission block 25.
[0027] During operation, when it is necessary to perform moisture-proof protection on the bottom end of the box body 1, after placing the bottom end of the box body 1 inside the protection frame 12, the installation frame 2 is simultaneously inserted into the limiting groove 3 inside the side of the protection frame 12, so that the storage groove 31 and the limiting groove 3 are at the same horizontal position, and then the adjusting bolt 21 is screwed to drive the push block 22 to move synchronously inside the installation frame 2 toward one side of the surface of the box body 1, until the inclined surface of the push block 22 contacts the inclined surface of the transmission block 25, and as the push block 22 continues to move, a corresponding outward driving force can be provided to the transmission block 25, so that the transmission block 25 can drive the movable rod 24 to move horizontally synchronously inside the guide groove 4, and provide a corresponding horizontal driving force to the insertion block 27 to make it move from the storage groove 4 to the insertion groove 27. After being moved out of the receiving groove 31 and inserted into the plug-in groove 28, the limit groove 3 can provide corresponding limiting force for the insertion block 27, so as to prevent the protective frame 12 from arbitrarily detaching from the outer bottom of the box body 1 and affecting its moisture-proof quality for the bottom end of the box body 1. When the protective frame 12 needs to be disassembled, it is only necessary to reversely twist the adjusting bolt 21 so that the pushing block 22 loses the pushing force on the transmission block 25. Then, under the reverse pushing action of the reset spring 26, the corresponding reverse pushing force can be provided to the movable rod 24, so that the insertion block 27 is synchronously moved out of the plug-in groove 28 and placed inside the storage. After the box body 1 is lifted, it can be moved out of the protective frame 12, and the protective frame 12 can be reused for moisture-proof protection.
