[0001] The utility model relates to the technical field of packaging cartons, in particular to a packaging carton with an anti-squeezing function. Background Art

[0002] Packaging cartons are made of paper products and are used to package various items. They are divided into single-hole / double-hole / triple-hole / quadruple-hole cartons. Cartons are further divided into paper boxes, color boxes, color boxes and oversized odd-shaped beer boxes. Packaging cartons are often used to transport and protect products, and there are strict requirements on their own quality. Therefore, a packaging carton with anti-squeezing function is needed.

[0003] When operators pack and transport items, they often use corresponding packaging cartons. Although existing cartons can achieve the function of packaging and transportation, the packaging cartons will be squeezed during actual use, and then the box body may be deformed, thereby causing damage to the items inside. In addition, packaging cartons are often sealed with tape, which makes it inconvenient to take and place the items inside, and the practicality is reduced. Utility Model Content

[0010] Preferably, raised bars are fixedly installed at equal distances on the bottom of the box body, and the sizes of the raised bars are the same.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the process of daily use of this packaging carton with anti-squeezing function, when the box body is squeezed by external force during handling or transportation, the squeezing force will be transmitted to the block, thereby causing the block to be compressed inside the slide groove. At the same time, the block will transmit the squeezing force to the movable rod, thereby causing the slider to slide on the surface of the round rod and the inside of the strip groove. Then the slider will squeeze the squeezing spring to put it in a compressed state. The squeezing force can be buffered by the provided squeezing spring and the movable rod, thereby reducing the possibility of deformation of the box body and protecting the items inside the box body.

[0013] In daily use of the packaging carton with anti-squeezing function, the operator places the items at the bottom of the box, then places the cover on the top of the box, and then aligns the card block with the card slot. At this time, the cover is continuously pressed, and then the card block is placed in the card slot. At the same time, the upper Velcro and the lower Velcro will fit together, and then it can be sealed. Otherwise, it can be opened. The upper Velcro and the lower Velcro can be set to change the traditional tape packaging, which is convenient for taking and placing items, and increases its practicality.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a packaging carton with an anti-squeezing function, comprising a box body 1, a slide groove 2 is opened around the interior of the box body 1, a return spring 3 is fixedly installed inside the slide groove 2, the outer surface of the return spring 3 is movably connected to the inner surface of the slide groove 2, and one end of the return spring 3 is fixedly installed with a block 4 located inside the box body 1. When the block 4 is squeezed, it will drive the return spring 3 to be squeezed inside the slide groove 2, so that it is in a compressed state, which can buffer part of the squeezing force, and strip grooves 5 are opened on both sides of the interior of the box body 1, and round rods 6 are fixedly installed inside the strip grooves 5. Slide blocks 7 are movably sleeved on the surfaces of the round rods 6. The inner surface of the slide block 7 and the outer surface of the round rod 6 are smooth, so that the slide block 7 can slide more smoothly inside the strip groove 5, reducing There is less chance of jamming, the outer surface of the slider 7 is movably connected to the inner surface of the strip groove 5, and an extrusion spring 8 is fixedly installed between the slider 7 and the strip groove 5. The inner surface of the extrusion spring 8 is movably connected to the outer surface of the round rod 6. When the slider 7 slides inside the strip groove 5, the extrusion spring 8 will be squeezed, thereby putting it in a compressed state, and a movable rod 9 is hinged between the slider 7 and the block 4. When the block 4 slides, it will drive the movable rods 9 on both sides to move synchronously. A cover plate 10 is movably installed on the top of the box body 1, and the cover plate 10 can encapsulate the box body 1. A card block 11 is fixedly installed around the bottom of the cover plate 10, and the card block 11 is adapted to the card groove 13, and an upper Velcro 12 is fixedly installed on the bottom of the card block 11, and the upper Velcro 12 and the lower Velcro 14 can be used in combination.

[0021] A card slot 13 is provided around the top of the box body 1, and a lower Velcro 14 is fixedly installed at the bottom of the inner part of the card slot 13. The upper Velcro 12 and the lower Velcro 14 are respectively the hook surface and suede surface of the Velcro. The hook surface is made of synthetic fibers such as polyamide or polyester, and the surface is covered with many small angle hooks, which can be buckled on the suede surface so that the Velcro plays a connecting role. The suede surface is made of materials such as polyester or nylon, and the surface is smooth, which can be connected to the hook surface. This structure makes it possible for the hook and loop to combine to form a temporarily fastened state when the two fabrics are pressed tightly. If the two need to be separated, they can be separated by force. Long grooves 17 are provided on both sides of the surface of the box body 1. A groove sleeve 18 is fixedly installed inside the long groove 17, and the long groove 17 and the groove sleeve 18 are convenient for carrying the box 1. A protective frame 15 is fixedly installed around the surface of the box 1. The number of the protective frames 15 is four, and the number and size of the four protective frames 15 are the same. The protective frame 15 can protect the corners of the box 1, thereby improving the strength of the box 1. Raised bars 16 are fixedly installed at equal distances on the bottom of the box 1, and the sizes of the raised bars 16 are the same. When the box 1 is placed on the ground, the raised bars 16 will first contact the ground, and then the box 1 will be in a suspended state, thereby isolating the moisture on the ground and preventing it from invading the interior of the box 1 and causing damage to the box 1.

[0022] Working principle: When the packaging carton needs to be used, the operator first places the article at the bottom end of the box body 1, then places the cover plate 10 on the top of the box body 1, and then aligns the card block 11 with the card slot 13. At this time, continue to press the cover plate 10, and then place the card block 11 inside the card slot 13. At the same time, the upper Velcro 12 and the lower Velcro 14 will fit together, and it can be sealed, otherwise it can be unsealed. Secondly, when the box body 1 is squeezed by external force during handling or transportation, the squeezing force will be transmitted to the block 4, thereby driving the block 4 to be compressed inside the slide groove 2. At the same time, the block 4 will transmit the squeezing force to the movable rod 9, thereby driving the slider 7 to slide on the surface of the round rod 6 and the inside of the strip groove 5. Then the slider 7 will squeeze the squeezing spring 8, making it in a compressed state, thereby buffering the squeezing force and reducing the damage caused to the box body 1, thereby more effectively protecting the articles.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
