Technical Field

[0001] This utility model relates to the field of cardboard boxes, specifically a corrugated cardboard box with a lid that can be vertically fixed. Background Technology

[0002] Corrugated cardboard boxes are widely used because they have many unique advantages. Corrugated cardboard has a hollow structure, which uses minimal materials to create a rigid box, making it relatively lightweight and reusable, thus reducing packaging costs. According to patent document CN217321636U, a corrugated cardboard box is disclosed, comprising a main body, a breathable mesh panel, and a waterproof layer. The main body has handle grooves on both sides, and the vent holes are fitted with breathable mesh panels. The inner surface of the main body is covered with a waterproof layer. The corrugated cardboard box includes a cover plate, on which a storage box is mounted. A sliding cover plate is located at the top of the storage box, and limit blocks are located on both sides of the top of the storage box. These limit blocks, under the action of a telescopic spring, form a left-right moving structure, allowing the sliding cover plate to be fixed to the storage box. Ventilation holes are located on both sides of the bottom of the storage box, and breathable mesh panels are installed inside the ventilation holes, facilitating heat exchange between the air inside the storage box and the air inside the main body. This lowers the internal temperature of the main body, maximizing the freshness of the items inside. The inner surface of the main body is covered with a waterproof layer to prevent damage from melting ice.

[0003] Traditional corrugated cardboard boxes have a lid with a switch at the opening. However, there is no structure on the box to vertically fix the lid when it is opened. When it is flipped open, it falls down naturally, taking up space. With repeated flipping over a long period of time, the joints also wear and tear, leading to damage. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a corrugated cardboard box with a vertically fixed lid. This solves the problem mentioned in the background art that the traditional corrugated cardboard box has a lid with a switch at the box opening. However, when the lid is opened, the box does not have a structure to vertically fix the lid. When it is flipped open, it will fall down naturally, taking up space. In addition, with repeated flipping over a long period of time, the connection will also wear out and become damaged. To achieve the above objectives, the present invention provides the following technical solution: a corrugated cardboard box with a lid that can be vertically fixed, comprising a lid disposed on the box body, wherein a vertical fixing component is disposed between the box body and the lid; The vertical fixing assembly includes a rear positioning bracket rod. A protective bottom sleeve frame is fitted around the bottom of the outer end of the housing. The rear positioning bracket rod is vertically and movably disposed at the rear end of the protective bottom sleeve frame. A positioning movable assembly is provided between the protective bottom sleeve frame and the rear positioning bracket rod. A connector is provided at the bottom of the housing, and the other end of the connector is rotatably connected to the housing. An external opening is provided at the rear end of the housing. An insert rod is installed above the inner end of the rear positioning bracket rod, and the other end of the insert rod passes through the connector and is inserted into the external opening.

[0005] Preferably, the positioning movable component includes a movable inner plate, and an inner movable groove is provided at the rear end of the protective bottom sleeve frame. The movable inner plate is movably installed inside the inner movable groove. Multiple sets of positioning springs are provided between the movable inner plate and the inner movable groove. The other end of the movable inner plate extends to the outside of the inner movable groove and is connected to the rear positioning frame rod through a rotating structure.

[0006] Preferably, the rotating structure includes a rotating rod, an inner groove is provided in the middle of the rear end of the movable inner plate, the rotating rod is horizontally installed inside the inner groove, a rotating cylinder is rotatably connected to the rotating rod, and the other end of the rotating cylinder is installed at the bottom of the rear positioning frame rod.

[0007] Preferably, a rear protruding pad is provided between the connector and the housing, and the rear protruding pad is glued to the corresponding position on the rear wall of the housing.

[0008] Preferably, a positioning and anti-slip component is provided between the housing and the protective bottom sleeve frame. The positioning and anti-slip component includes an inner support frame, which is movably installed below the inner end of the housing. Multiple sets of inner protective layers are evenly distributed and glued to the bottom of the inner wall of the protective bottom sleeve frame, and multiple sets of anti-slip protrusions are evenly distributed and glued to the bottom of the protective bottom sleeve frame.

[0009] Preferably, elastic side pressure plates are installed at both ends of the top of the protective bottom frame, and the box body is located between the two sets of elastic side pressure plates.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The present invention provides a technical solution: a corrugated cardboard box with a lid that can be vertically fixed, including a lid 101 disposed on the box body 1, and a vertical fixing component disposed between the box body 1 and the lid 101. The vertical fixing assembly includes a rear positioning bracket 207. A protective bottom sleeve frame 2 is fitted onto the bottom of the outer end of the housing 1. The rear positioning bracket 207 is vertically and movably positioned at the rear end of the protective bottom sleeve frame 2. A positioning movable assembly is provided between the protective bottom sleeve frame 2 and the rear positioning bracket 207. A connector 210 is provided at the bottom of the housing 1, and the other end of the connector 210 is rotatably connected to the housing 1. An external opening 209 is provided at the rear end of the housing 1. An insert rod 208 is installed above the inner end of the rear positioning bracket 207. The other end of the insert rod 208 passes through the connector 210 and is inserted into the external opening 209. Inside, a rotatable connector 210 is provided at the connection between the lid 101 and the body 1 to prevent damage when the lid 101 is bent due to long-term flipping. When the lid 101 is upright, the rear positioning bracket 207 fixes the connector 210 to the body 1 and also drives the insertion rod 208 to pass through the connector 210 and insert it into the outer opening 209 to fix the connection and perform the vertical fixation operation of the lid 101. The above avoids the problem of it falling naturally when flipped open, occupying space, and also avoids wear and damage to the connection due to long-term flipping.

[0017] Please see Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8The positioning movable component includes a movable inner plate 202. An inner movable groove 201 is provided at the rear end of the protective bottom sleeve frame 2. The movable inner plate 202 is movably installed inside the inner movable groove 201. Multiple sets of positioning springs 203 are provided between the movable inner plate 202 and the inner movable groove 201. The other end of the movable inner plate 202 extends to the outside of the inner movable groove 201 and is connected to the rear positioning frame rod 207 via a rotating structure. The rotating structure includes a rotating rod 205. An inner groove 204 is provided in the middle of the rear end of the movable inner plate 202. The rotating rod 205 is horizontally installed inside the inner groove 204. A rotating cylinder 206 is rotatably connected to the rotating rod 205, and the other end of the rotating cylinder 206 is installed at the bottom of the rear positioning frame rod 207. Connector 21 A rear protruding pad 212 is provided between the box 0 and the box body 1. The rear protruding pad 212 is glued to the corresponding position on the rear wall of the box body 1. Since the rotating rod 205 is connected to the inner groove 204 opened at the rear end of the movable inner plate 202, the rotating cylinder 206 rotatably connects the rear positioning bracket rod 207 to the rotating cylinder 206. When the insertion rod 208 is pulled out, if there is no obstruction, the rear positioning bracket rod 207 can be flipped to a horizontal state with the movable inner plate 202 to avoid obstructing its flipping position when the box cover 101 is closed. When the connecting piece 210 is flipped to the upright state on the box body 1 along with the box cover 101, the connecting piece 210 and the rear protruding pad 212 are in contact with each other. The rear protruding pad 212 is made of rubber, which can improve the friction at the connection and prevent slippage.

[0018] Please see Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9A positioning and anti-slip assembly is provided between the box body 1 and the protective bottom frame 2. The positioning and anti-slip assembly includes an inner support frame 3, which is movably installed below the inner end of the box body 1. Multiple sets of inner protective layers 301 are evenly distributed and glued to the bottom of the inner wall of the protective bottom frame 2, and multiple sets of anti-slip protrusions 302 are evenly distributed and glued to the bottom of the protective bottom frame 2. Elastic side pressure plates 211 are installed at both ends of the top of the protective bottom frame 2, and the box body 1 is positioned between two sets of elastic side pressure plates 211. The inner protective layer 301 is located between the box body 1 and the protective bottom frame 2, and both the inner protective layer 301 and the anti-slip protrusions 302 are made of rubber. When the box body 1 is placed inside the protective bottom frame 2 to protect the bottom, multiple sets of inner protective layers 301, which are made of rubber, are provided on the contact surface between the box body 1 and the protective bottom frame 2. The protective bottom sleeve 2 protects the contact surface. When the protective bottom sleeve 2 contacts the plane, the rubber anti-slip protrusions 302 increase the friction of the contact surface, making the placement surface more stable. At the same time, the inner support frame 3 is supported inside the box 1. The height of the inner support frame 3 is greater than that of the protective bottom sleeve 2, so it can support both the inside and outside of the box 1 at the same time, avoiding the problem that the box 1 cannot support heavy objects. When the protective bottom sleeve 2 is fitted on the outside of the box 1, since the elastic side pressure plate 211 and the protective bottom sleeve 2 are integrated into the structure, the elastic side pressure plate 211 is elastic. The inner walls of both ends of the elastic side pressure plate 211 are attached to the two ends of the outer wall of the box 1, which can generate friction at the connection point with the outer wall, further improving the stability of the connection of the protective bottom sleeve 2.

[0019] Working Principle: Traditional corrugated cardboard boxes typically have a lid 101 attached to the box body 1. During prolonged use and repeated flipping of the lid 101, a protective bottom sleeve 2 is fitted over the box body 1, allowing it to directly contact the ground or other flat surfaces. This protects the bottom of the box body 1 from wear and tear over time. Simultaneously, when the lid 101 is flipped into an upright position, a connector 210 is provided at the connection between the lid 101 and the box body 1 for easy flipping. The connector 210 is made of plastic and rotatably connects to the box body 1, preventing damage to the lid 101 from repeated bending. An externally movable inner panel 202 is also included, with a rear positioning rod 207 mounted on it. The other end of 02 is movably installed inside the inner movable groove 201. Under the action of external pulling force, it drives the movable inner plate 202 to move inside the inner movable groove 201, stretching the positioning spring 203, so as to drive the insertion rod 208 to be pulled out of the outer opening 209 and the insertion state of the connector 210, causing the box cover 101 to fall. When the box cover 101 is vertical, the rear positioning bracket 207 fixes the connector 210 to the box body 1, and also drives the insertion rod 208 to pass through the connector 210 and be inserted into the outer opening 209 to fix the connection and perform the vertical fixation operation of the box cover 101. The above avoids the problem of it falling naturally when it is flipped open, occupying space, and also avoids the connection from being easily worn and damaged under long-term flipping. When the box 1 is placed inside the protective bottom frame 2 to protect the bottom, multiple sets of inner protective layers 301 made of rubber are provided on the contact surface between the box 1 and the protective bottom frame 2 to protect the contact surface. When the protective bottom frame 2 contacts the plane, the anti-slip protrusions 302 of the rubber material can increase the friction of the contact surface during contact with the plane, making the placement surface more stable. At the same time, the inner support frame 3 is supported inside the box 1. The height of the inner support frame 3 is greater than that of the protective bottom frame 2, so that the inner and outer sides of the box 1 can be supported at the same time, avoiding the problem that the box 1 is not able to support the object when placing a heavy object. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
