Description

Technical Field

[0001] This utility model relates to the field of product packaging technology, specifically a packaging box with a handle that can be quickly assembled. Background Technology

[0002] Handle-operated packaging boxes are widely used in the transportation and sales of electronic products, gifts, wines, and high-end consumer goods. Traditional handle-operated packaging boxes mostly adopt a fixed structure, with the handle connected to the box body by nails, adhesives, or complex snap-fit ​​structures. This type of structure mainly has the following drawbacks: Inconvenient assembly: Many packaging boxes are flat when shipped to save shipping space, requiring consumers to fold, insert, and secure them themselves. The process is cumbersome, and if glue or multiple small parts are involved, the assembly experience is poor and inefficient.

[0003] Unreliable connection: The handles of some packaging boxes are not strong enough to connect to the box body. They are prone to detachment or damage when bearing heavy loads or being carried unsteadily, posing a safety hazard. Connection reliability is especially crucial when the contents are heavy.

[0004] Difficult to disassemble and poor reusability: Fixed connections or disposable snap-fit ​​structures are difficult to disassemble without damage after the first use. This is very inconvenient when users need to remove the contents and store the packaging, or when the packaging box needs to be recycled after transportation, which is inconsistent with the concept of green environmental protection.

[0005] Parts are easily lost: If the handle is a separate unit, small parts are easily lost when not in use or after disassembly, making the entire packaging box unusable.

[0006] Therefore, there is an urgent need in this field for a handle packaging box solution that can ensure connection strength and stability, enable quick, tool-free assembly and disassembly, and has a high degree of integration of components and is not easily lost. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a packaging box with a handle that can be quickly assembled. Through a clever linkage locking structure, it achieves quick and stable assembly and convenient disassembly of the packaging box.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A quick-assembly handle-type packaging box includes a box body and a storage box placed inside the box body. The storage box has a storage cavity containing a storage rack. A handle is provided on the top of the storage box. Two L-shaped locking connectors are fixedly connected to the handle and can rise and fall synchronously with the handle on the back of the storage box. A back plate is slidably inserted into the back of the storage box and is simultaneously inserted into the box body. A vertical movable groove is provided on the side of the back plate near the storage box. Two slots corresponding to the positions of the L-shaped locking connectors are provided on the upper wall of the movable groove. When the handle is pulled upward, the L-shaped locking connectors are driven to rise and horizontally engage with the corresponding slots, thereby locking the storage box, back plate, and box body together.

[0009] Furthermore, the two adjacent outer side walls of the box body are respectively provided with interconnected strip grooves and strip holes.

[0010] Furthermore, a limiting insert is fixedly installed on one side of the back plate. When the back plate is installed on the box, the limiting insert is inserted into the strip groove, and the main body of the back plate is inserted into the strip hole and remains flush with the outer wall of the box.

[0011] Furthermore, the back plate has a first strip groove on the side away from the storage box and a second strip groove on the side closer to the storage box.

[0012] Furthermore, two parallel dovetail strips are fixedly installed on the back of the storage box, and two dovetail grooves that are adapted to the dovetail strips are opened on the side of the back plate near the storage box.

[0013] Furthermore, the storage box is provided with two vertically distributed sliding cavities, and an L-shaped connecting rod is slidably installed in each of the two sliding cavities. One end of the L-shaped connecting rod is fixedly connected to the handle, and the other end is fixedly connected to the corresponding L-shaped snap-fit ​​connector.

[0014] Furthermore, the width of the movable groove is greater than or equal to the sum of the widths of the two L-shaped card connectors.

[0015] Furthermore, the depth of the slot is adapted to the length of the horizontal section of the L-shaped card connector.

[0016] The beneficial effects of this utility model are as follows: Users only need to complete three simple actions: "put in the storage box", "insert the back panel", and "lift the handle". The storage box, back panel and box body can be firmly locked together by the L-shaped clip connector and the slot. The whole process does not require any tools, glue or extra parts, and the assembly efficiency is extremely high, resulting in a good user experience. The locking mechanism achieved through the upward-lifting handle directly converts the vertical lifting force on the handle into a horizontal clamping force between the L-shaped locking connector and the back panel, resulting in a clear and rational force transmission path. This rigid locking method has a strong load-bearing capacity, far superior to traditional adhesive or simple hook-and-loop connections, effectively preventing the risk of components loosening when carrying heavy objects, thus ensuring high safety. When it is necessary to disassemble the packaging, simply press down on the handle to disengage the L-shaped clip from the slot, releasing the locking mechanism and allowing easy removal of the back panel and storage box. This process does not damage any parts, enabling the packaging box to be completely disassembled, neatly stored, and reused multiple times, greatly enhancing the product's environmental friendliness and practical value. All key moving parts (handles, L-shaped clips, L-shaped connecting rods) are integrated into the storage box, with the back panel connected to the box via a plug-in connection. Even when disassembled, the components remain a cohesive whole or several easily manageable parts, effectively preventing the scattering and loss of small parts and facilitating management and reassembly.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, and several embodiments of the utility model will be provided. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0021] Example 1, please refer to Figure 1-6 This utility model provides a technical solution: A quick-assembly handle-type packaging box includes a box body 1 and a storage box 2 placed inside the box body 1. The storage box 2 has a storage cavity, in which a storage rack 21 for fixing and cushioning the contents is placed. The top of the storage box 2 is provided with a handle 22 for easy carrying. The back of the storage box 2 is provided with two L-shaped locking connectors 23 that are fixedly connected to the handle 22 and can rise and fall synchronously with the handle 22. A back plate 3 for closing the back of the box body and achieving linkage locking is slidably inserted into the back of the storage box 2. The back plate 3 is also inserted into the box body 1. A movable groove 35 is provided on the side of the back plate 3 near the storage box 2 for the vertical movement of the L-shaped locking connectors 23. Two slots 36 corresponding to the positions of the L-shaped locking connectors 23 are provided on the upper wall of the movable groove 35. When the handle 22 is pulled upward, the handle 22 drives the L-shaped locking connectors 23 to rise through the L-shaped connecting rod 24 and horizontally lock into the corresponding slots 36, thereby locking the storage box 2, the back plate 3 and the box body 1 together. The two adjacent outer side walls of the box body 1 are respectively provided with interconnected strip grooves 11 and strip holes 12. A positioning insert 33 for positioning and limiting is fixedly installed on one side of the back plate 3. When the back plate 3 is installed on the box body 1, the positioning insert 33 is inserted into the strip groove 11, and the main body of the back plate 3 is inserted into the strip hole 12 and is flush with the outer side wall of the box body 1. A first strip groove 31 for enhancing structural strength is provided on the side of the back plate 3 away from the storage box 2, and a second strip groove 32 for reducing weight and maintaining structural stability is also provided on the side closer to the storage box 2. Two parallel dovetail strips 25 are fixedly installed on the back of the storage box 2. Two dovetail grooves 34 adapted to the dovetail strips 25 are opened on the side of the back plate 3 near the storage box 2. The storage box 2 and the back plate 3 are precisely guided and stably connected through the dovetail connection structure. The storage box 2 is provided with two vertically distributed sliding cavities. L-shaped connecting rods 24 for transmitting lifting action are slidably installed in both sliding cavities. The cross-section of the sliding cavity is preferably non-circular, such as rectangular or circular with guide key, to ensure that the L-shaped connecting rods 24 can only move in the vertical direction and will not rotate during the lifting process, thereby ensuring that the L-shaped snap-fit ​​connectors 23 can be accurately aligned and snapped into the slots 36. One end of the L-shaped connecting rod 24 is fixedly connected to the handle 22, and the other end is fixedly connected to the corresponding L-shaped snap-fit ​​connectors 23 to form a complete force transmission path. The width of the movable slot 35 is greater than or equal to the sum of the widths of the two L-shaped connectors 23, ensuring that the L-shaped connectors 23 can move freely up and down within the movable slot 35 without interference. The depth of the slot 36 is adapted to the length of the horizontal section of the L-shaped connector 23, ensuring a firm connection and reasonable force distribution. The sliding cavity is equipped with a guide structure to ensure that the L-shaped connecting rod 24 maintains a stable movement trajectory during the lifting process and does not deflect. The storage rack 21 adopts a segmented foam structure, which can be customized according to the product shape and provides effective cushioning protection. The edge of the strip hole 12 of the box body 1 is provided with a sealing lip. The sealing lip can be made of a flexible material (such as rubber, silicone or elastic plastic), or it can be integrally formed with the box body 1 and have a certain elasticity. When the back plate 3 is inserted, the sealing lip undergoes elastic deformation to form an interference fit, which not only enhances the stability and tightness of the overall structure, but also prevents abnormal noise caused by shaking between components. After the back plate 3 is inserted, a tight fit is formed, enhancing the stability of the overall structure. Example

[0022] To further enhance the safety and ease of opening of the packaging box during transportation, an inertial locking mechanism is also provided inside the sliding cavity of the storage box 2. This mechanism includes a counterweight slidably mounted on the L-shaped connecting rod 24 and a limiting recess formed in the inner wall of the sliding cavity. In its natural state, the counterweight is located below the limiting recess. When the packaging box is subjected to bumps and vibrations during transportation, the counterweight slides upwards due to inertia and locks into the limiting recess. At this time, part of the counterweight's structure blocks the L-shaped locking connector 23 from above or to the side, preventing it from moving downwards, thus achieving automatic locking during transportation and effectively preventing accidental loosening. When the packaging box is stationary, the counterweight falls out of the limiting recess and resets under its own weight, releasing the obstruction of the L-shaped locking connector 23. At this point, the user can easily unlock the box by pressing down the handle 22.

[0023] The other structures are consistent with the embodiments.

[0024] Work process Assembly steps: First, place the storage box 2 into the box body 1. Then, hold the back plate 3 and align its dovetail groove 34 with the dovetail strip 25 on the back of the storage box 2. Slide the back plate 3 in, while ensuring that the limiting insert 33 on the back plate 3 is aligned with the strip groove 11 on the box body 1. Continue to push the back plate 3 until the limiting insert 33 is fully inserted into the strip groove 11 and the main body of the back plate 3 is fully embedded in the strip hole 12 of the box body 1. At this time, the outer surface of the back plate 3 is flush with the outer side wall of the box body 1. At this time, the two L-shaped snap-fit ​​connectors 23 on the back of the storage box 2 are located in the movable groove 35 of the back plate 3. Finally, pull the handle 22 upwards. The handle 22 drives the two L-shaped locking connectors 23 to rise synchronously through the L-shaped connecting rod 24. When the L-shaped locking connectors 23 rise to the top of the movable slot 35, their horizontal sections will be locked into the corresponding horizontal slots 36, thereby forming a rigid constraint in the horizontal direction and tightly locking the storage box 2, the back plate 3 and the box body 1 together. At this time, the packaging box is in a state that can be safely carried. Disassembly steps: When disassembly is required, simply press down on handle 22 to move L-shaped clip 23 out of horizontal slot 36 and down into movable slot 35, thus releasing the locking state. Then, the back plate 3 can be pulled out from the box 1 and storage box 2, and finally the storage box 2 can be removed.

[0025] 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.
