[0001] The utility model relates to the technical field of corrugated cartons, in particular to a corrugated carton with high compressive strength. Background Art

[0002] A corrugated carton is a packing box made of corrugated cardboard. The structure of the corrugated carton consists of three layers of cardboard: face paper, corrugated paper and bottom paper, which is light, strong and has buffering performance, and can effectively protect items from being damaged during transportation.

[0003] In the prior art, there is a patent document with the publication number of CN208086473U. The technical solution of this patent document includes a carton body. Lifting holes are opened on a pair of opposite side walls of the carton body. A sliding groove is arranged at the upper end of the lifting hole. A shielding plate that can move up and down is arranged in the sliding groove. The upper end of the shielding plate is detachably connected to the upper end of the sliding groove. When the upper end of the shielding plate abuts against the upper end of the sliding groove, the shielding plate is completely embedded in the sliding groove. When the lower end of the shielding plate abuts against the lower end of the lifting hole, the upper end of the shielding plate is located in the sliding groove. This patent document has the functions of convenient lifting of the corrugated carton and dust not easily entering the corrugated carton through the lifting hole.

[0004] The above and prior arts have the following defects: When stacking corrugated cartons filled with products together, the corrugated cartons at the lower layer are prone to deformation or even breakage due to excessive force, resulting in the collapse of the corrugated cartons and damage to the products, thereby reducing the practicability of the corrugated cartons.

[0005] Therefore, a corrugated carton with high compressive strength is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to solve the defect that the corrugated cartons at the lower layer are prone to deformation or even breakage due to excessive force, resulting in the collapse of the corrugated cartons and damage to the products, and to propose a corrugated carton with high compressive strength.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme: A corrugated carton with high compressive strength includes a box shell. A box cover is fixedly connected to the surface of the box shell. Both the box shell and the box cover are made of corrugated paper. A reinforcement structure is arranged on the outer wall of the box shell. The reinforcement structure includes a reinforcing sleeve. The reinforcing sleeve is slidably connected to the outer wall of the box shell. A clamping block is slidably connected in the reinforcing sleeve. The clamping block penetrates through the box shell. An inclined support is fixedly connected to the surface of the clamping block. One end of the inclined support is fixedly connected to a support plate.

[0008] The effects achieved by the above components are as follows: By setting the reinforcement structure, when stacking corrugated cardboard boxes together, the cooperation of the support plate, the inclined plane, and the clamping block can improve the compressive strength of the corrugated cardboard box, prevent the corrugated cardboard box from being damaged, thereby extending the service life of the corrugated cardboard box. The reinforcement sleeve can reinforce the box shell and prevent the box shell from being broken, greatly improving the practicability of the corrugated cardboard box.

[0009] Preferably, two fixing blocks are fixedly connected to the surface of the reinforcement sleeve. A sliding rod is slidably connected inside the fixing block. One end of the sliding rod is fixedly connected with a limiting ring, and the limiting ring is engaged with the clamping block.

[0010] The effects achieved by the above components are as follows: After the limiting ring is engaged with the clamping block, the limiting ring plays a role in restricting the position of the clamping block.

[0011] Preferably, an inclined plane is formed on the surface of the clamping block.

[0012] The effects achieved by the above components are as follows: During the sliding process of the clamping block, the inclined plane of the clamping block will contact the limiting ring, and the inclined plane of the clamping block will squeeze the limiting ring, causing the two limiting rings to slide towards each other.

[0016] The effects achieved by the above components are as follows: Since the spring is always in a stretched state, the spring will use its own tensile force to automatically slide the limiting ring towards the direction close to the fixing block.

[0017] Preferably, a positioning block is fixedly connected to the surface of the reinforcement sleeve. The positioning block is slidably connected with the limiting ring.

[0018] The effects achieved by the above components are as follows: When the limiting ring slides and contacts the positioning block, the positioning block can prevent the limiting ring from continuing to slide, so that the limiting ring is aligned with the inclined plane on the surface of the clamping block.

[0019] Preferably, a rectangular plate is fixedly connected to the surface of the reinforcement sleeve. Two traction ropes are slidably connected inside the rectangular plate. One end of each traction rope is fixedly connected with the limiting ring, and the upper ends of the two traction ropes are fixedly connected with a pulling plate.

[0020] The effects achieved by the above components are as follows: When it is necessary to remove the reinforcement sleeve, pull the pull plate upward. The pull plate will drive the traction rope to pass through the rectangular plate. The rectangular plate will adjust the sliding direction of the traction rope. The traction rope will drive the two limit rings to slide towards each other, so that the limit rings are disengaged from the contact with the clamping blocks.

[0028] In order to more clearly understand the above objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0029] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0030] Such as Figures 1 - 4As shown in the figure, the present utility model provides a corrugated cardboard box with high compressive strength, which includes a box shell 1. A box cover 2 is fixedly connected to the surface of the box shell 1. Both the box shell 1 and the box cover 2 are made of corrugated paper. A reinforcement structure 3 is provided on the outer wall of the box shell 1. The reinforcement structure 3 includes a reinforcement sleeve 301. The reinforcement sleeve 301 is slidably connected to the outer wall of the box shell 1. A clamping block 302 is slidably connected inside the reinforcement sleeve 301. The clamping block 302 penetrates the box shell 1. An inclined strut 303 is fixedly connected to the surface of the clamping block 302. One end of the inclined strut 303 is fixedly connected to a support plate 304. Two fixing blocks 305 are fixedly connected to the surface of the reinforcement sleeve 301. A sliding rod 306 is slidably connected inside the fixing block 305. One end of the sliding rod 306 is fixedly connected to a limiting ring 307. The limiting ring 307 is snap-fitted with the clamping block 302. After the limiting ring 307 is snap-fitted with the clamping block 302, the limiting ring 307 functions to limit the position of the clamping block 302. An inclined surface 313 is provided on the surface of the clamping block 302. During the sliding process of the clamping block 302, the inclined surface 313 of the clamping block 302 will contact the limiting ring 307, and the inclined surface 313 of the clamping block 302 will squeeze the limiting ring 307, causing the two limiting rings 307 to slide towards each other.

[0031] As Figure 3 and Figure 4 shown, the sliding rod 306 has a regular hexagonal prism structure. The sliding rod 306 with a regular hexagonal prism structure can limit the sliding path of the limiting ring 307 and prevent the limiting ring 307 from rotating. A spring 308 is sleeved on the surface of the sliding rod 306. Both ends of the spring 308 are fixedly connected to the limiting ring 307 and the fixing block 305 respectively. The spring 308 is always in a stretched state. Therefore, the spring 308 will use its own pulling force to automatically slide the limiting ring 307 towards the direction close to the fixing block 305. A positioning block 309 is fixedly connected to the surface of the reinforcement sleeve 301. The positioning block 309 is slidably connected to the limiting ring 307. The sliding of the limiting ring 307 will contact the positioning block 309. The positioning block 309 can prevent the limiting ring 307 from continuing to slide, so that the limiting ring 307 is aligned with the inclined surface 313 on the surface of the clamping block 302. A rectangular plate 310 is fixedly connected to the surface of the reinforcement sleeve 301. Two towing ropes 311 are slidably connected inside the rectangular plate 310. One end of each towing rope 311 is fixedly connected to the limiting ring 307. The upper ends of the two towing ropes 311 are fixedly connected to a pulling plate 312. When it is necessary to remove the reinforcement sleeve 301, pull the pulling plate 312 upward. The pulling plate 312 will drive the towing ropes 311 to pass through the rectangular plate 310. The rectangular plate 310 will adjust the sliding direction of the towing ropes 311. The towing ropes 311 will drive the two limiting rings 307 to slide towards each other, so that the limiting ring 307 is separated from the clamping block 302.

[0032] The overall working principle is as follows: When it is necessary to strengthen the box shell 1, the reinforcing sleeve 301 is sleeved on the outer wall of the box shell 1, and then the clamping block 302 is passed through the box shell 1. During this process, the spring 308 is always in a stretched state. Therefore, the spring 308 will use its own pulling force to make the limiting ring 307 slide towards the direction close to the fixed block 305. The sliding of the limiting ring 307 will contact the positioning block 309, and the positioning block 309 can prevent the limiting ring 307 from continuing to slide, so that the limiting ring 307 is aligned with the inclined surface 313 on the surface of the clamping block 302. The sliding rod 306 with a regular hexagonal prism structure can limit the sliding path of the limiting ring 307 and prevent the limiting ring 307 from rotating. During the sliding process of the clamping block 302, the inclined surface 313 will contact the limiting ring 307, and the inclined surface 313 of the clamping block 302 will squeeze the limiting ring 307, causing the two limiting rings 307 to slide towards each other. The sliding of the limiting ring 307 will stretch the spring 308 again. When the inclined surface 313 of the clamping block 302 is disengaged from the limiting ring 307, the spring 308 will contract again, and the limiting ring 307 will be engaged with the clamping block 302 by the pulling force of the spring 308. The limiting ring 307 plays a role in restricting the position of the clamping block 302. When stacking corrugated cardboard boxes together, the cooperation of the support plate 304, the inclined surface 313 and the clamping block 302 can improve the compressive strength of the corrugated cardboard boxes and prevent the corrugated cardboard boxes from being damaged, thereby extending the service life of the corrugated cardboard boxes. The reinforcing sleeve 301 can reinforce the box shell 1 and prevent the box shell 1 from being broken. When it is necessary to remove the reinforcing sleeve 301, pull up the pull plate 312. The pull plate 312 will drive the traction rope 311 to pass through the rectangular plate 310. The rectangular plate 310 will adjust the sliding direction of the traction rope 311. The traction rope 311 will drive the two limiting rings 307 to slide towards each other, so that the limiting ring 307 is disengaged from the clamping block 302. Then the clamping block 302 can be taken out of the reinforcing sleeve 301, and then the reinforcing sleeve 301 can be removed, so that the reinforcement structure 3 can be reused.

[0033] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
