Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a packaging box with a compression-resistant structure. Background Art

[0002] Packaging boxes are mainly used as outer packaging for various products and foods. At present, there are many types of packaging boxes, which can not only serve as packaging for storing items, but also serve as decorations. At the same time, they can also ensure the safety of items during transportation.

[0003] Among them, the "compression-resistant packaging box" disclosed in the authorization number "CN219468302U" has a specific technical structure. Through the upper reinforcement plate, the lower reinforcement plate and the connecting plate, the upper reinforcement plate and the lower reinforcement plate cooperate with the connecting plate to simultaneously reinforce the packaging box body at the upper end, lower end, corners and other parts of the outer side of the packaging box body, thereby effectively improving the compression resistance of the packaging box body.

[0004] However, although the packaging box has effectively improved the compression resistance of the packaging box body, the packaging box is easily subjected to multiple collisions during transportation, so that the single-layer compression resistance structure is insufficient to resist the impact force caused by the collision, resulting in the gifts inside the packaging box being damaged during the collision, thereby reducing the compression protection effect of the packaging box.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] As introduced in the background art, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a packaging box with a pressure-resistant structure.

[0025] See also Figure 1-Figure 7A packaging box with a pressure-resistant structure includes a hard bottom plate 1 and fixed blocks 2, the fixed blocks 2 are fixedly installed on both sides of the top of the hard bottom plate 1, and the number of fixed blocks 2 on each side is two groups, the hard bottom plate 1 includes a packaging box main body 101 and a packaging box liner 102, the packaging box main body 101 is fixedly installed on the top of the hard bottom plate 1, and the packaging box liner 102 is movably installed inside the packaging box main body 101, a rotating rod 201 is rotatably installed between the fixed blocks 2, outer protective covers 202 are rotatably installed on both sides of the top of the hard bottom plate 1, the rotating rod 201 and the outer protective cover 202 are fixedly connected, a buffer anti-pressure plate 106 is movably installed between the packaging box main body 101 and the packaging box liner 102, and a pressure-resistant honeycomb panel 107 is fixedly installed inside the buffer anti-pressure plate 106.

[0026] Specifically, by installing the buffering pressure-resistant plate 106 and the pressure-resistant honeycomb plate 107 between the packaging box body 101 and the packaging box liner 102, since the material of the pressure-resistant honeycomb plate 107 is light and has high compressive strength, the buffering pressure-resistant plate 106 and the pressure-resistant honeycomb plate 107 provide internal pressure protection for the packaging box liner 102, and the outer protective cover 202 is driven by the rotating rod 201 to flip and close on the outside of the packaging box body 101, so that the outer protective cover 202 provides external pressure protection for the packaging box liner 102. The combination of the internal and external pressure protection of the outer protective cover 202 and the pressure-resistant honeycomb plate 107 solves the problem of damage to the gifts inside the packaging box liner 102 due to the impact force generated by multiple collisions during transportation, and improves the pressure resistance effect of the device.

[0027] Furthermore, a groove 103 is formed at the bottom of the hard bottom plate 1, through grooves 104 are formed on both sides of the bottom of the packaging box body 101, and a first limiting rod 105 is rotatably mounted on the bottom of the packaging box liner 102. The first limiting rod 105 passes through the through groove 104 and extends into the interior of the groove 103;

[0028] Furthermore, a lining 108 is movably installed inside the packaging box liner 102, and baffles 109 are fixedly installed at the front end, rear end and both sides of the inner wall of the packaging box liner 102, and the baffles 109 are located on the top of the lining 108;

[0029] Specifically, the first limiting rod 105 is horizontally extended through the through slot 104 to the inside of the groove 103, and then the first limiting rod 105 is rotated to a vertical state, and is located inside the groove 103 to limit the packaging box liner 102, so that the packaging box liner 102 is fixedly installed inside the packaging box body 101, and the baffle 109 limits the lining 108, so that the lining 108 is fixedly installed inside the packaging box liner 102 to package the gift;

[0030] Furthermore, the front and rear ends of the top of the hard base plate 1 are provided with limiting grooves 203, and the bottom of the inner wall of the outer protective cover 202 is fixedly mounted with an insert block 204, which extends into the interior of the limiting groove 203;

[0031] Furthermore, fixed buckles 205 are fixedly installed at the front and rear ends of the top of the outer protective cover 202, and a rubber belt 206 is movably installed between the fixed buckles 205;

[0032] Furthermore, an L-shaped limit plate 3 is fixedly installed at the front and rear ends of the outer protective cover 202 on one side, and a second limit rod 301 is rotatably installed at the front and rear ends of the outer protective cover 202 on the other side. The second limit rod 301 extends to the inner side of the L-shaped limit plate 3. A cavity 302 is formed at the front and rear ends of the outer protective cover 202 on one side. A limit block 303 is movably installed inside the cavity 302. The limit block 303 extends to the inner side of the L-shaped limit plate 3. A spring 304 is fixedly installed inside the cavity 302, and the limit block 303 is fixedly connected to the spring 304.

[0033] Specifically, when the outer protective cover 202 is rotated and closed on the outside of the packaging box body 101, the insert block 204 slides into the inside of the limiting groove 203, and then the second limiting rod 301 is rotated toward the inside of the L-shaped limiting plate 3. Since the top of the limiting block 303 is an inclined surface, the limiting block 303 contracts toward the inside of the cavity 302 to squeeze the spring 304 to generate elastic force. After the second limiting rod 301 extends to the inside of the L-shaped limiting plate 3, the elastic force of the spring 304 acts on the limiting block 303 to extend the limiting block 303 to the top of the second limiting rod 301 for limiting, so that the outer protective cover 202 is fixedly closed to the outside of the packaging box body 101 for pressure protection, and the packaging box body 101 is convenient to carry by pulling the fixing ring buckle 205.

[0034] Working principle: First, place the gift inside the lining 108 for packaging, then rotate the outer protective cover 202 to close it on the outside of the packaging box body 101, at this time the insert block 204 slides into the inside of the limiting groove 203, then rotate the second limiting rod 301 to extend to the inner side of the L-shaped limiting plate 3, and the elastic force of the spring 304 acts on the limiting block 303, so that the limiting block 303 extends to the top of the second limiting rod 301 to limit it, so that the outer protective cover 202 is fixedly closed on the outside of the packaging box body 101. When it is collided during transportation, the outer protective cover 202 performs the first pressure protection. When it is collided more and generates a greater impact force, when the impact force is transmitted to the packaging box body 101, the pressure-resistant honeycomb panel 107 provides inner pressure protection, and the double-layer pressure protection mechanism prevents the gifts inside the lining 108 from being damaged.

[0035] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
