Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically to a four-sided truncated pyramidal packaging box assembly structure. Background Technology

[0002] Packaging boxes are an important part of product packaging, used to protect, display, and showcase products. They not only enhance the product's grade and attractiveness but also increase the enjoyment of using the product. However, traditional packaging boxes are prone to loosening due to insufficient sealing, which can lead to items inside the box falling out and getting damaged.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese patent publication number CN203199407U, publication date 2013-09-18) provides a three-dimensional packaging box with an inner box. Both the box body and the lid are truncated pyramidal in shape. A rectangular groove is provided on the upper surface of the box body; a rectangular inner box is placed within the rectangular groove; a positioning threaded hole is located at the center of the inner side of the lower surface of the box body; a locking hole is provided on the lid corresponding to the positioning threaded hole; a locking bolt is inserted into the locking hole and connected to the positioning threaded hole. The structure is simple and easy to manufacture. When the packaging box is opened, the items inside will not fall out; the locking bolt, inserted into the locking hole and connected to the positioning threaded hole, reliably secures the box body and lid. It is suitable for use as a packaging box for storing valuable items such as jewelry and watches.

[0004] The aforementioned mechanism places the items inside a rectangular inner box and then uses locking bolts to connect the box body to the lid. However, in actual use, additional tools are required to open the packaging; otherwise, forcibly opening the packaging may damage the box. Therefore, it is not suitable for storing frequently used items and has low applicability. Utility Model Content

[0005] The purpose of this utility model is to provide a quadrangular frustum packaging box assembly structure to solve the problem mentioned in the background art that traditional packaging boxes are prone to loosening due to insufficient locking during use, which in turn leads to the items placed inside the packaging box falling out and being damaged.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quadrangular frustum packaging box assembly structure, including a fixed base plate, with a display box disposed at the top of the fixed base plate; a fixing groove is disposed on the left side of the bottom end of the display box, and a locking mechanism for splicing with the fixed base plate is disposed on the right side of the bottom end of the display box, the locking mechanism including a limiting block disposed on the right side of the top end of the fixed base plate, and a limiting groove matching the limiting block disposed on the right side of the bottom end of the display box; a limiting strip is disposed on the outer side of the top end of the fixed base plate, and an anti-slip mechanism for increasing friction is disposed on the top end of the display box.

[0007] Furthermore, the upper outer end of the limiting block is chamfered, and the diameter of the upper outer end of the limiting block is smaller than the diameter between the lower inner ends of the limiting groove.

[0008] Furthermore, the anti-slip mechanism includes an anti-slip groove, which is located on the outside of the display case. Anti-slip protrusions are provided on both sides of the anti-slip groove, and the anti-slip protrusions are located at the corners of the outside of the display case.

[0009] Furthermore, the anti-slip grooves and anti-slip protrusions are both inclinedly arranged on the outside of the display case, and the anti-slip grooves are symmetrical about the vertical central axis of the display case.

[0010] Furthermore, a placement platform is provided at the middle position of the top of the fixed base plate, and the height of the placement platform is greater than the height of the fixed base plate.

[0011] Furthermore, the display box is positioned above the placement platform, and the inner length and width of the display box are both greater than the length and width of the placement platform.

[0012] Furthermore, the bottom end of the fixing groove is fitted with the top end of the fixing base plate, and the top end of the limiting strip is fitted with the bottom end of the display box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By placing the display case on the surface of the fixed base plate, the items can be placed on the platform inside the fixed base plate. At the same time, the height of the items placed is higher than the horizontal height of the fixed base plate itself. This allows for better observation of the items placed between the fixed base plate and the display case. It also allows for timely observation of the display and storage status of the items placed inside the display case, increasing the applicability during use.

[0015] Furthermore, when the fixed base plate and the display box are assembled and connected, the interlocking of the limiting groove and the limiting block makes the fixed base plate and the display box more secure, avoiding the problem of loose connection between the packaging boxes. At the same time, the interlocking splicing between the limiting groove and the limiting block allows the fixed base plate and the display box to be flexibly assembled and disassembled, avoiding the situation where the packaging cannot be opened and forcibly damaged.

[0016] Furthermore, the upper outer side of the limiting block is chamfered, and the diameter of the chamfer is smaller than the diameter between the lower inner sides of the limiting groove, so that the limiting block can be better engaged inside the limiting groove.

[0017] 2. The fixed base plate and the display box are combined into a cube, which makes the packaging boxes easy to stack and store after assembly, thus effectively reducing the space occupied by the packaging boxes during storage and increasing the overall applicability during use.

[0018] Furthermore, the anti-slip grooves and protrusions on the outside of the display case can increase the anti-slip performance when the display case is held, preventing the packaging box from slipping from the hand and causing the items to fall when the packaging box is unpacked or assembled, thus increasing the stability of the packaging box during use. At the same time, the anti-slip grooves and protrusions set at an angle make it easier for users to look down and observe the items placed inside. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figure 1 , Figure 3 and Figure 4The technical solution shown addresses the problem of traditional packaging boxes often failing to lock securely, leading to loosening and damage to items inside. This truncated pyramidal packaging box assembly structure discloses a locking mechanism, including a fixed base plate 1. A placement platform 9 is located at the top center of the fixed base plate 1, with the height of the platform 9 exceeding the height of the fixed base plate 1. A locking mechanism for splicing with the fixed base plate 1 is located on the right side of the bottom of the display box 2. This locking mechanism includes a limiting block 8, located on the top right side of the fixed base plate 1. A limiting groove 7 matching the limiting block 8 is located on the right side of the bottom of the display box 2. The upper outer edge of the limiting block 8 has a chamfer, and the diameter of the upper outer edge of the limiting block 8 is smaller than the diameter between the lower inner edges of the limiting groove 7. A fixing groove 6 is located on the left side of the bottom of the display box 2.

[0028] In this example, display case 2 is placed on the surface of fixed base plate 1. The placement platform 9 inside fixed base plate 1 allows for the placement of items, ensuring the items are placed at a height higher than the fixed base plate 1 itself. This allows for better observation of the items placed between fixed base plate 1 and display case 2, and also enables timely monitoring of the items' display and storage status, increasing usability. When fixed base plate 1 and display case 2 are joined together, the interlocking of limiting groove 7 and limiting block 8 secures the fixed base plate 1 and display case 2 more firmly, preventing packaging box damage. The problem of loose interlocking connections is addressed by utilizing the interlocking connection between the limiting groove 7 and the limiting block 8, allowing for flexible assembly and disassembly of the fixed base plate 1 and the display box 2, preventing situations where the packaging cannot be opened and forced damage occurs. The upper outer end of the limiting block 8 is chamfered, and the diameter of the chamfer is smaller than the diameter between the lower inner ends of the limiting groove 7, allowing the limiting block 8 to better engage inside the limiting groove 7. The cooperation between the limiting strip 5 and the fixing groove 6 provides a limiting function when assembling the fixed base plate 1 and the display box 2, preventing excessive pressing during assembly and increasing the overall stability during use.

[0029] Example 2: Figure 5 and Figure 6 The technical solution shown is designed to address the problem that when items are stored in a packaging box, it is inconvenient to stack and store the boxes, which takes up too much space. The four-sided truncated box assembly structure discloses an assembly mechanism. A display box 2 is provided at the top of the fixed base plate 1. The bottom end of the fixed groove 6 is attached to the top end of the fixed base plate 1. The top end of the limiting strip 5 is attached to the bottom end of the display box 2. The display box 2 is placed above the placement platform 9, and the inner length and width of the display box 2 are both greater than the length and width of the placement platform 9.

[0030] In this example, multiple fixed base plates 1 and display boxes 2 are spliced ​​together, with the display boxes 2 connected to each other and the fixed base plates 1 on the outside. This not only protects the items placed inside the packaging box, but also allows the fixed base plates 1 and display boxes 2 to be combined into a cube. This makes the packaging boxes easy to stack and store after assembly, effectively reducing the space occupied by the packaging boxes during storage and increasing the overall usability during use.

[0031] Example 3: Figures 1-4 The technical solution shown addresses the problem of slippage during assembly and disassembly of the packaging box. The truncated pyramidal packaging box assembly structure includes an anti-slip mechanism. A limiting strip 5 is provided on the outer side of the top of the fixed base plate 1, and an anti-slip mechanism to increase friction is provided on the top of the display box 2. The anti-slip mechanism includes an anti-slip groove 3, which is located on the outer side of the display box 2. Anti-slip protrusions 4 are provided on both sides of the anti-slip groove 3, and the anti-slip protrusions 4 are located at the corners on the outer side of the display box 2. Both the anti-slip groove 3 and the anti-slip protrusions 4 are inclined on the outer side of the display box 2, and the anti-slip groove 3 is symmetrical about the vertical central axis of the display box 2.

[0032] In this example, the anti-slip grooves 3 and anti-slip protrusions 4 provided on the outside of the display box 2 can increase the anti-slip performance of the display box 2 when it is held, avoid the problem of the packaging box slipping from the hand and causing the items to fall when the packaging box is disassembled, and increase the stability of the packaging box during use. At the same time, the anti-slip grooves 3 and anti-slip protrusions 4 provided at an angle can make it easier for the user to look down and observe the items placed inside.

[0033] 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.
