Description

Technical Field

[0001] This invention relates to the field of packaging box technology, specifically to a packaging box that is easy to assemble and stack. Background Technology

[0002] Packaging boxes are specialized containers used for the storage, transportation, and protection of goods. As a core supporting product in logistics and commodity circulation, their materials, specifications, and structures are flexibly designed according to the characteristics, weight, and transportation environment of the goods they carry, combining practicality, protection, and economy. Currently, the most common packaging boxes on the market are mainly divided into four categories: paper, wood, plastic, and metal. Among them, paper packaging boxes are widely used for packaging light industrial products such as food, electronics, and daily necessities due to their lightweight, environmental friendliness, low cost, and ease of printing; wooden packaging boxes are sturdy, durable, and have strong load-bearing capacity, making them suitable for the transportation and securing of heavy objects such as large machinery, building materials, and heavy equipment; plastic packaging boxes are waterproof, moisture-proof, and corrosion-resistant, and are mostly used for fresh produce, chemical products, and other items that require moisture protection and damage prevention; metal packaging boxes have extremely high pressure resistance and impact resistance, and are often used for long-distance transportation and long-term storage of special items such as precision instruments and dangerous goods. Packaging boxes not only effectively protect the contents from external dust, moisture, and impacts, but also facilitate stacking, handling, and counting, improving logistics efficiency. Some boxes can also be printed with brand logos, product information, and warning labels, serving a promotional and cautionary purpose. With the increasing popularity of environmental awareness, foldable, recyclable, and biodegradable green packaging boxes are gradually becoming mainstream. These boxes reduce packaging costs and environmental burden, playing an indispensable role in all stages of production, logistics, and consumption, silently protecting goods and ensuring their safe arrival at the point of sale.

[0003] Existing rigid plastic packaging boxes typically consist of a box body and a lid. After the items are placed inside the box, the lid is placed on top of the box. When the boxes are stacked horizontally, two boxes are usually placed sideways. This can easily lead to relative displacement between the two horizontally placed boxes during subsequent stacking or transportation, affecting the stability of the boxes during stacking and making them inconvenient to stack. At the same time, the lid simply covers the top of the box body, allowing external dust to easily enter the gap between the lid and the box body, which can easily cause dust contamination of the items inside the box. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a packaging box that is easy to assemble and stack, which has the advantages of convenient stacking, stable stacking, and reduced dust contamination of the contents, thus solving the problems mentioned in the background art.

[0005] The present invention provides the following technical solution: a packaging box that is easy to splice and stack, including a box body, a box cover is provided on the top of the box body, sealing components fixed to the box body are provided on both sides of the box cover, a connecting component is fixed to the outer wall of the box body, and a snap-fit ​​component is provided on the right side wall of the box cover;

[0006] The connecting assembly includes a lower snap-fit ​​component and an upper snap-fit ​​component fixed to the outer wall of the box cover, wherein the upper snap-fit ​​component is engaged with the top of the lower snap-fit ​​component;

[0007] The snap-fit ​​assembly includes a rotating component rotatably connected to the cover, a snap-fit ​​strip fixed to the bottom of the rotating component, a rotating shaft fixed to the side wall of the rotating component, and a mating component fixed to the outer wall of the box on the side away from the rotating component.

[0008] Preferably, the sealing assembly includes a fixing strip fixed to the outer wall of the box and a right-angle strip fixed to the top of the fixing strip, wherein a metal strip is embedded inside the right-angle strip.

[0009] Preferably, the outer wall of the box cover has a side groove, and the right-angle strip fits into the inside of the side groove.

[0010] Preferably, the top of the upper snap-fit ​​component is machined with a plurality of snap-fit ​​holes that mate with the snap-fit ​​blocks, and the top of the lower snap-fit ​​component is fixedly connected with a plurality of snap-fit ​​blocks.

[0011] Preferably, the right side wall of the box cover is machined with a groove, and a triangular strip that cooperates with the rotating part is provided inside the groove.

[0012] Preferably, a torsion spring is provided on the outside of the rotating shaft to cooperate with the rotating component, and the rotating component is rotatably connected to the inside of the groove.

[0013] Preferably, the right side wall of the box is fixedly connected with a parallel outer strip, and the left side wall of the box is fixedly connected with a parallel inner strip.

[0014] Preferably, the mating part has a mating hole machined on its top, and the mating part is disposed on the top of the upper snap-fit ​​part.

[0015] Preferably, the rotating member is disposed on the top of the lower snap-fit ​​member, and the outer strip is fitted on both sides of the lower snap-fit ​​member.

[0016] Preferably, the top of the box is fixed with multiple protrusions, and the four corners of the box cover are machined with grooves that match the protrusions.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When this type of packaging box, which is easy to splice and stack, is connected horizontally, the first packaging box is placed first, and then the upper snap-fit ​​piece on the left side wall of the other packaging box is engaged with the lower snap-fit ​​piece of the first packaging box to snap-fit ​​connection. At this time, the snap-fit ​​block of the lower snap-fit ​​piece enters the snap-fit ​​hole of the upper snap-fit ​​piece, and at the same time, the inner strip engages with the outer strip, thereby enabling the two packaging boxes to be spliced ​​and connected horizontally, which facilitates the subsequent stacking of the packaging boxes and facilitates the transportation of the packaging boxes.

[0019] 2. This type of packaging box, which is easy to splice and stack, allows for stacking. When a third packaging box is placed on top of the first packaging box, the third packaging box will press against the rotating part of the lid of the first packaging box, causing the right end of the rotating part to rotate downwards. After the second packaging box is connected, the mating part engages with the bottom of the rotating part, allowing the locking strip to enter the mating hole of the mating part after the rotating part rotates. At this time, the pressure of the upper packaging box during stacking can be used to perform a secondary locking between the two horizontally connected packaging boxes. This, combined with the locking of the upper and lower locking parts, improves the stability of the two horizontally connected packaging boxes after connection, further enhancing the stability of the packaging boxes during stacking.

[0020] 3. In this type of packaging box that is easy to splice and stack, when the third packaging box is placed on top of the first packaging box, the right-angle strip is located inside the side groove of the box lid. The pressure of the third packaging box makes the right-angle strip press tightly into the side groove, thereby using the right-angle strip to block the two sides of the box lid, so as to reduce the entry of external dust into the gap between the box lid and the box body, and reduce the risk of external dust entering the interior of the box body and contaminating the stored items.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-8 A packaging box that is easy to splice and stack includes a box body 1, a box cover 2 is provided on the top of the box body 1, sealing components are provided on both sides of the box cover 2 and glued to the box body 1, a connecting component is glued to the outer wall of the box body 1, and a snap-fit ​​component is provided on the right side wall of the box cover 2. The connecting component includes a lower snap-fit ​​4 and an upper snap-fit ​​9 that are fixed to the outer wall of the box cover 2 by bolts.

[0032] In some embodiments, when two boxes are horizontally joined, the upper snap-fit ​​member 9 on the left side wall of the other box is engaged with the lower snap-fit ​​member 4 of the first box for a snap-fit ​​connection. At this time, the snap-fit ​​block 401 of the lower snap-fit ​​member 4 enters the snap-fit ​​hole 901 of the upper snap-fit ​​member 9, while the inner strip 902 engages with the outer strip 3. Thus, the upper snap-fit ​​member 9 is snap-fitted onto the top of the lower snap-fit ​​member 4. Simultaneously, the inner strip 902 engaging with the outer strip 3 prevents front-to-back displacement when the two boxes are stacked.

[0033] The snap-fit ​​assembly includes a rotating part 5 rotatably connected to the cover 2, a snap-fit ​​strip 501 fixed to the bottom of the rotating part 5 by bolts, a rotating shaft 503 glued to the side wall of the rotating part 5, and a mating part 6 fixed to the outer wall of the housing 1 on the side away from the rotating part 5 by bolts.

[0034] Please see Figure 1 , Figure 8 The sealing assembly includes a fixing strip 7 that is bolted to the outer wall of the housing 1 and a right-angle strip 8 that is glued to the top of the fixing strip 7. A metal strip 801 is embedded inside the right-angle strip 8.

[0035] Please see Figure 3 The outer wall of the box cover 2 has a side groove 201, and the right angle strip 8 fits into the inside of the side groove 201.

[0036] In some embodiments, the side groove 201 is provided with anti-slip texture parallel to the metal strip 801. When the top of the right-angled strip 8, which is made of common rubber, is pressed from above, the metal strip 801 is pressed so that the right-angled strip 8 can be pressed and pressed against the inside of the side groove 201 more stably. The metal strip 801 is a common stainless steel wire.

[0037] Please see Figure 1 , Figure 5 The top of the upper snap-fit ​​component 9 has multiple snap-fit ​​holes 901 that fit into the snap-fit ​​block 401, and the top of the lower snap-fit ​​component 4 has multiple snap-fit ​​blocks 401 glued and fixed.

[0038] Please see Figure 4 The right side wall of the box cover 2 has a groove, and a triangular strip 502 that matches the rotating part 5 is set inside the groove.

[0039] In some embodiments, the rotating member 5 is subjected to the action of the torsion spring, which causes the right end of the rotating member 5 to rotate upward. At the same time, the upper part of the left end of the rotating member is blocked and limited by the triangular strip 502, which makes the rotating member 5 tilted upward on the right. This can prevent the rotating member 5 from being in a vertical state and affecting the stacking of the packaging boxes above. At the same time, the tilted state can prevent the horizontal packaging boxes from being jammed and stacked.

[0040] Please see Figure 7 The rotating shaft 503 is provided with a torsion spring that cooperates with the rotating part 5, and the rotating part 5 is rotatably connected to the inside of the groove.

[0041] Please see Figure 1 , Figure 2 The right side wall of the box 1 is fixed with parallel outer strips 3 by bolts, and the left side wall of the box 1 is fixed with parallel inner strips 902 by bolts.

[0042] Please see Figure 2 The mating part 6 has a mating hole machined on its top, and the mating part 6 is set on the top of the upper snap-fit ​​part 9.

[0043] Please see Figure 1 The rotating part 5 is located on the top of the lower locking part 4, and the outer strip 3 is fitted on both sides of the lower locking part 4.

[0044] Please see Figure 2 The top of the box body 1 is glued and fixed with multiple protrusions, and the four corners of the box cover 2 are machined with grooves that match the protrusions, which can be used to position the box cover 2.

[0045] Working principle: When the packaging boxes are placed horizontally, the first packaging box is placed first, and then the upper snap-fit ​​9 on the left side wall of the second packaging box is engaged with the lower snap-fit ​​4 of the first packaging box for snap-fit ​​connection. At this time, the snap-fit ​​block 401 of the lower snap-fit ​​4 enters the snap-fit ​​hole 901 of the upper snap-fit ​​9, and at the same time, the inner strip 902 engages with the outer strip 3, thereby enabling the two packaging boxes to be horizontally spliced ​​together, which facilitates the subsequent stacking of the packaging boxes and facilitates the transportation of the packaging boxes. When the packaging boxes are stacked upwards, the third packaging box is placed on top of the box body 1 of the first packaging box. At this time, the third packaging box will press against the rotating part 5 of the box cover 2 of the first packaging box, causing the right end of the rotating part 5 to rotate downwards. After the second packaging box is connected, the mating part 6 engages with the lower part of the rotating part 5. This allows the rotating part 5 to rotate and the locking strip 501 to enter the mating hole of the mating part 6. At this time, the pressure of the upper packaging box when stacking upwards can be used to perform a secondary locking between the two horizontally connected packaging boxes. This, together with the locking of the upper locking part 9 and the lower locking part 4, improves the stability of the connection between the two horizontally connected packaging boxes, further enhancing the stability when the packaging boxes are stacked. While the third packaging box is placed on top of the box body 1 of the first packaging box, the right angle strip 8 is located inside the side groove 201 of the box cover 2. The pressure of the box body 1 of the third packaging box makes the right angle strip 8 press tightly against the inside of the side groove 201. Thus, the right angle strip 8 can block the two sides of the box cover 2 to reduce the entry of external dust into the gap between the box cover 2 and the box body 1, thereby reducing the risk of external dust entering the inside of the box body 1 and contaminating the stored items.
