Description

Technical Field

[0001] This utility model relates to the field of cardboard boxes, specifically a corrugated cardboard box with wear-resistant edges and corners. Background Technology

[0002] Corrugated cardboard is used to construct a rigid box with minimal material, making it more robust than similar cardboard boxes. Due to its superior performance and good processing properties, corrugated cardboard boxes have gradually replaced wooden boxes and other transport packaging containers.

[0003] According to patent document CN217624640U, an anti-wear corrugated cardboard box is disclosed, including a corrugated cardboard box body and a corrugated cardboard box lid. The corners of the corrugated cardboard box body are wrapped with anti-wear edging, and the corners of the corrugated cardboard box lid are wrapped with anti-wear edging. Buffer mechanisms are provided at the four bottom corners of the anti-wear edging of the box body and the anti-wear edging of the box lid. At the four corners where the anti-wear edging of the box body and the anti-wear edging of the box lid connect, locking mechanisms are provided. This utility model, through the setting of anti-wear edging of the box body and the anti-wear edging of the box lid, can cover the corners of the corrugated cardboard box that are most prone to wear. When the corrugated cardboard box collides and rubs against the ground or other objects, it will always preferentially contact the anti-wear edging of the box body and the anti-wear edging of the box lid, which can effectively reduce the wear of the corrugated cardboard box and greatly increase its service life. At the same time, the anti-wear edging of the box body and the anti-wear edging of the box lid, which have a certain structural strength, can also prevent the corrugated cardboard box from deforming and breaking under pressure to a certain extent.

[0004] Currently, traditional corrugated cardboard boxes consist of a box body and a lid. Based on the above-mentioned use of the four corners, that is, the edge treatment, there is no supporting structure in the middle when subjected to external forces. This makes it easy for the outer box panel to lean inward, causing the box to deform. At the same time, it is not easy to maintain the edges and corners, and it is not easy to better prevent wear and tear at the edges and corners. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a corrugated cardboard box with wear-resistant edges and corners. This solves the problem mentioned in the background art that the current traditional corrugated cardboard boxes are made of a box body and a box lid. According to the above-mentioned edge-wrapping treatment at the four corners, there is no supporting structure in the middle when subjected to external forces. This makes it easy for the outer box panel to lean inward, causing the box to deform. At the same time, it is not easy to maintain the edges and corners and effectively prevent wear at the edges and corners.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a corrugated cardboard box with wear-resistant edges and corners, including a box cover disposed on the box body, and wear-resistant components disposed on the outside of the box body and the box cover;

[0007] The wear-resistant component includes an outer casing frame and an outer casing cover frame. The outer casing frame is fitted around both ends of the casing, and the outer casing cover frame is fitted around both ends of the casing cover. A corresponding U-shaped connecting frame is installed between the outer casing frame and the outer casing cover frame. An inner positioning frame is provided at the inner end of the connection between the casing and the casing cover, and a corresponding frame opening is installed between the inner positioning frame and the U-shaped connecting frame.

[0008] Preferably, sleeve plates are installed at both ends of the outer wall of the U-shaped connecting frame at both ends, and a corresponding inner limiting plate is installed at the top of the inner positioning frame.

[0009] Preferably, the lid is positioned between the inner limiting plate and the U-shaped connecting frame, and the frame opening is positioned at the connection between the box body and the lid.

[0010] Preferably, a T-shaped inner rod is movably installed inside the front and rear sleeve plates, and a limiting pressure cylinder is threaded onto the front end of the T-shaped inner rod.

[0011] Preferably, multiple sets of anti-slip strips are glued to the middle of the outer surface of the T-shaped inner rod, and the anti-slip strips are made of rubber.

[0012] Preferably, the inner walls of the outer box frame and the outer box cover frame are both glued with a protective layer, and the other end of the protective layer is in contact with the corresponding position of the outer surface of the box and the box cover.

[0013] Preferably, the two ends of the U-shaped connecting outer frame are provided with an inner movable groove, and the inner walls of the two inner movable grooves are provided with corresponding springs.

[0014] Preferably, the ends of the U-shaped connecting frames at both ends that are closest to each other are glued with end pads, and the end pads are made of rubber.

[0015] Preferably, the bottom of the box is provided with a protective component, which includes a protective base plate. The protective base plate is installed below the inner end of the outer box frame at both ends, and the box is placed on the protective base plate. An anti-slip pad is provided below the protective base plate, and the bottom of the anti-slip pad is provided with anti-slip texture. Both ends of the top of the anti-slip pad are provided with a card insertion block. Card slots are opened on both sides of the bottom of the protective base plate, and the other end of the card insertion block is inserted into the corresponding card slot.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By incorporating anti-wear components, a U-shaped connecting frame with a width greater than both the outer carton frame and the outer carton lid frame is provided at the connection point between the outer carton frame and the outer carton lid frame. The two ends of the U-shaped connecting frame are positioned at the outer ends of the connection point between the carton and the outer carton lid frame, pressing the carton lid onto the frame opening. This structure makes the anti-wear structure of the carton a unified whole, ensuring that the carton is properly supported after being placed inside. This avoids the problem of only protecting the four corners, which makes it difficult to maintain the edges and corners when subjected to external forces in the middle. This better prevents damage to the edges and corners and external parts.

[0018] 2. By setting up protective components, the bottom of the box is protected when it is placed on the protective base plate. The bottom of the protective base plate is equipped with anti-slip pads. When the card block is inserted into the corresponding card slot, the anti-slip pads are connected to the protective base plate. The bottom of the anti-slip pads also has anti-slip textures, so as to avoid slipping when the box is placed on it. Attached Figure Description

[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10 This utility model provides a technical solution: a corrugated cardboard box with wear-resistant edges and corners, including a box cover 101 set on the box body 1, and wear-resistant components are provided on the outside of the box body 1 and the box cover 101;

[0032] The wear-resistant components include an outer casing frame 2 and an outer casing cover frame 201. The outer casing frame 2 is fitted onto both ends of the outer casing 1, and the outer casing cover frame 201 is fitted onto both ends of the outer casing cover 101. A corresponding U-shaped connecting frame 202 is installed between the outer casing frame 2 and the outer casing cover frame 201. An inner positioning frame 205 is provided at the inner end of the connection between the casing 1 and the casing cover 101, and a corresponding frame opening 204 is installed between the inner positioning frame 205 and the U-shaped connecting frame 202. The wear-resistant components are further enhanced by providing a width greater than [missing information - likely a measurement or design feature]. The U-shaped connecting frame 202 of the outer carton frame 2 and the outer carton cover frame 201 allows the two ends of the U-shaped connecting frame 202 to be attached to the outer ends of the connection between the carton 1 and the outer carton cover frame 201, pressing the carton cover 101 onto the frame opening 204, which is located between the inner positioning frame 205 and the U-shaped connecting frame 202. This structure makes the anti-wear structure of the carton a whole, and after the carton is placed inside, it is fully supported, so as to avoid the problem that only the four corners are protected, and the edges and corners are not easy to maintain when the middle is subjected to external forces. This better prevents damage to the edges and corners and the outside.

[0033] Please see Figure 2 , Figure 4 , Figure 6 , Figure 8 and Figure 10 Both ends of the outer wall of the U-shaped connecting frame 202 are equipped with sleeve plates 3, and the top of the inner positioning frame 205 is equipped with a corresponding inner limiting plate 206; the box cover 101 is located between the inner limiting plate 206 and the U-shaped connecting frame 202, and the frame opening 204 is located at the connection between the box body 1 and the box cover 101; T-shaped inner rods 301 are movably installed inside the sleeve plates 3 at both ends, and the front end of the T-shaped inner rods 301 is threaded with a limiting pressure cylinder 302; multiple sets of anti-slip strips 303 are glued to the middle of the outer surface of the T-shaped inner rods 301, and the anti-slip strips 303 are made of rubber; the sleeve plates 3 are installed on the U-shaped connecting frame 202. The outer frame 202 has holes, with four sets for easy handling. T-shaped inner rods 301 are inserted into the front and rear end sleeves 3. The front end of the T-shaped inner rod 301 has an external thread that matches the internal thread of the limiting pressure cylinder 302. By rotating the limiting pressure cylinder 302, the limiting pressure cylinder 302 is threadedly connected to the front part of the T-shaped inner rod 301 to position the T-shaped inner rod 301. The T-shaped inner rods 301 installed at both ends are easier to move later. The middle of the outer surface of the T-shaped inner rod 301 is glued with an anti-slip strip 303. The anti-slip strip 303 is made of rubber to prevent hand slippage.

[0034] Please see Figure 4 and Figure 7 The inner walls of the outer box frame 2 and the outer box cover frame 201 are both glued with protective layers 207, and the other end of the protective layer 207 is in contact with the corresponding position of the outer surface of the box 1 and the box cover 101. The two ends of the U-shaped connecting outer frames 202 are each provided with an inner movable groove 210, and the inner wall of the inner movable groove 210 is provided with a corresponding spring 209. The two ends of the U-shaped connecting outer frames 202 are each glued with an end pad 208, which is made of rubber. The outer box frame 2 and the outer box cover frame 201 are both glued with a sponge protective layer 207 at the ends that contact the box 1, creating contact surfaces between the outer box frame 2 and the outer box cover frame 201 and the outer walls of the box 1 and the box cover 101. Further protection of the inner contact surface; each of the two U-shaped connecting outer frames 202 has an inner movable groove 210 at the end closest to the other, and a spring 209 is provided at the inner end of the inner movable groove 210 to connect the two U-shaped connecting outer frames 202. The spring 209 is elastic. When the two U-shaped connecting outer frames 202 are in the connected state, the inner walls of the U-shaped connecting outer frames 202 can be made to fit together. If the U-shaped connecting outer frames 202 are pulled outward, the spring 209 will be stretched when the U-shaped connecting outer frames 202 are moved outward under the action of force, so as to increase the distance between the two sets of U-shaped connecting outer frames 202. When in contact, the rubber end pads 208 provided on the contact surface can prevent wear when the two collide and protect the contact surface.

[0035] Please see Figure 2 , Figure 3 and Figure 9 The bottom of the box 1 is equipped with a protective component, which includes a protective base plate 203. The protective base plate 203 is installed on the lower part of the inner end of the outer box frame 2 at both ends, and the box 1 is placed on the protective base plate 203.

When the box 1 is placed on the protective base plate 203, the bottom is protected when the box is placed. The anti-slip mat 4 is provided on the bottom of the protective base plate 203. When the card insertion block 401 is inserted into the corresponding card slot 402, the anti-slip mat 4 and the protective base plate 203 can be connected. The bottom of the anti-slip mat 4 also has anti-slip texture, so as to avoid slipping when the box is placed on it.

[0036] Working principle: Traditional corrugated cardboard boxes consist of a box body 1 and a lid 101. In this case, the outer box frame 2 surrounds both ends of the box body 1, and the outer lid frame 201 surrounds both ends of the lid 101. At the connection point between the outer box frame 2 and the outer lid frame 201, a U-shaped connecting frame 202 with a width greater than both the outer box frame 2 and the outer lid frame 201 is provided. This allows the U-shaped connecting frames 202 to fit around the outer ends of the connection point between the box body 1 and the outer lid frame 201. A frame opening 204 is installed between the outer frame 202 and the inner positioning frame 205. The box cover 101 is pressed onto the frame opening 204 and positioned between the inner positioning frame 205 and the U-shaped connecting outer frame 202. This structure makes the anti-wear structure of the carton a whole. After the carton is placed inside, it is fully supported, which avoids the problem that the box is easily deformed when the center is subjected to external forces, and the corners are not easy to maintain. This better prevents wear and tear on the corners and the outside.

[0037] When the box is inside the outer box frame 2, the protective bottom plate 203 is located at the bottom of the outer box frame 2, so that the box 1 is placed on it. When the box is placed, the bottom is protected. At the same time, the bottom of the protective bottom plate 203 is provided with a rubber anti-slip pad 4. The anti-slip pad 4 and the card insertion block 401 are designed as an integral structure. When the card insertion block 401 is inserted into the corresponding card slot 402, the anti-slip pad 4 and the protective bottom plate 203 can be connected. The anti-slip pad 4 can also be disassembled and replaced. The bottom of the anti-slip pad 4 also has anti-slip texture, so when the box is placed on it, the anti-slip pad 4 at the direct contact end generates a certain friction with the surface, which also avoids the problem of slipping. The above is the working process of the whole device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0038] 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.
