Description

Technical Field

[0001] This utility model relates to a packaging box and belongs to the field of packaging boxes. Background Technology

[0002] Packaging boxes are containers used to hold, protect, and transport products. Their main functions include preventing product damage during transportation and handling, while also enhancing the product's grade and added value through exquisite design. Based on different materials, existing packaging boxes can generally be divided into cardboard boxes, tin boxes, wooden boxes, leather boxes, etc. With the rapid development of modern industry and the continuous improvement of people's living standards, the market demand for packaging boxes is gradually increasing, and people are also placing higher demands on the structural strength, aesthetics, and ease of use of packaging boxes.

[0003] However, existing packaging boxes generally suffer from the following shortcomings: the handles are mostly single-layered or single-sided thick designs, resulting in insufficient load-bearing capacity. They are prone to breakage under heavy loads, making the boxes inconvenient to carry and even causing product damage from drops. Therefore, there is an urgent need to improve the packaging box structure to enhance overall strength and the reliability of the handles. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings and deficiencies of the existing technology and to provide a packaging box.

[0005] A packaging box includes a box body. The top of the box body is provided with a first handle and a second handle formed by mating and splicing. The first handle has a mating hole, and the second handle has a fixing shaft for inserting into the mating hole. The first handle has a locking component for engaging and fixing with the fixing shaft after it is inserted into the mating hole. The locking component includes a drive rod rotatably mounted on the first handle. The first handle has a mounting cavity. The bottom of the drive rod extends into the mounting cavity and is connected to a drive part. The drive part has outwardly extending drive stops on both sides. The mounting cavity has a telescopic rod that is linked to the drive stops. The telescopic rod has a first slot and a second slot. When the drive stops engage with the first slot, the bottom of the telescopic rod extends outside the mounting cavity and engages with the drive rod.

[0006] This technical solution utilizes two handles joined together to form a single structure, significantly improving load-bearing strength and stability compared to a single-layer handle structure, thus avoiding the risk of handle breakage due to fragility during handling. The locking mechanism securely locks the fixed shaft, preventing the handle from loosening or separating during transport and enhancing carrying safety. By incorporating a drive unit within the mounting cavity, internal transmission and locking functions are achieved without increasing external volume, ensuring a compact structure and preventing external parts from affecting the aesthetics of the packaging. The multi-slot design of the telescopic rod allows the drive stop bar to be locked or unlocked with the fixed shaft at different positions, enhancing the structure's flexibility and applicability while improving the handle's locking stability.

[0007] Preferably, the first and second slots are arranged in a wave-like shape, and a connecting slope is provided between the first and second slots. The drive bar rotates and slides between the first and second slots through the connecting slope to switch and engage with one of the slots.

[0008] This technical solution, by designing the slot with a wave-like shape, creates a stable stop position after the drive bar is engaged, preventing accidental slippage of the telescopic rod under force and improving locking reliability. The inclined connecting surface allows the drive bar to slide smoothly along the surface during operation, achieving smooth switching between slots and avoiding operational jamming that could negatively impact the user experience.

[0009] Preferably, the telescopic rod includes a rod head, a first slot and a second slot are provided on the rod head, a rod body is provided at the bottom of the rod head, a spring is sleeved on the rod body, one end of the spring is fixedly connected to the bottom of the mounting cavity, and the other end abuts against the bottom of the rod head.

[0010] This technical solution, by setting the first and second slots on the head of the telescopic rod, enables centralized engagement with the drive stop bar, resulting in a compact structure and facilitating stable operation of the locking mechanism.

[0011] Furthermore, the bottom of the mounting cavity is connected to an mounting channel, and the bottom of the rod extends out of the mounting channel when the drive stop bar engages with the first slot.

[0012] This technical solution incorporates a spring on the rod, enabling the telescopic rod to automatically reset when pushed or released by the drive stop, thus improving operational convenience and structural reliability. One end of the spring is fixed to the bottom of the mounting cavity, while the other end abuts against the bottom of the rod head, ensuring that the telescopic rod is always subjected to elastic preload when under force, thereby preventing the locking mechanism from loosening and enhancing the stability and durability of the lock.

[0013] Furthermore, the bottom of the rod body is provided with a first locking groove, and the fixed shaft is provided with a second locking groove for engaging with the first locking groove.

[0014] This technical solution utilizes interlocking teeth between the rod and the fixed shaft to create a reliable meshing connection during locking, further enhancing the handle's stability. The meshing of the teeth effectively prevents the fixed shaft from rotating or loosening, ensuring the handle remains stable even under heavy loads and preventing accidental cracking or falling of the packaging box due to structural loosening.

[0015] Preferably, the first handle and the second handle are provided with a carrying port.

[0016] This technical solution incorporates a carrying handle with a finger opening, allowing users to easily insert their fingers for lifting and carrying, resulting in a more stable grip and improved carrying comfort. This structure also makes the packaging easier to lift and transport under load, reducing the risk of product drops due to a weak grip.

[0017] The beneficial effects of this utility model are as follows: By joining two handles together to form an integral structure, compared to a single-layer handle structure, the load-bearing strength and stability are significantly improved, avoiding the risk of handle breakage due to fragility during handling. The locking component can firmly lock the fixed shaft, preventing the handle from loosening or separating during handling, thus improving carrying safety. By setting a drive unit within the mounting cavity, internal transmission and locking functions can be achieved without increasing the external volume, ensuring a compact structure and avoiding affecting the aesthetics of the packaging box due to protruding external parts. The multi-slot design of the telescopic rod allows the drive stop bar to be locked or unlocked with the fixed shaft at different positions, enhancing the flexibility and applicability of the structure, while also improving the locking strength of the handle.

[0023] like Figure 1-5 The illustration shows an embodiment of a packaging box according to the present invention, comprising a box body 1. The top of the box body 1 is provided with a first handle 2 and a second handle 3 formed by joining and connecting. The first handle 2 is provided with a docking hole 21. The second handle 3 is provided with a fixing shaft 31 for inserting into the docking hole 21. The first handle 2 is provided with a locking component 4 for engaging and fixing with the fixing shaft 31 after it is inserted into the docking hole 21. The locking component 4 includes a drive rod 41 rotatably mounted on the first handle 2. The first handle 2 is provided with a mounting cavity 22. The bottom of the drive rod 41 extends into the mounting cavity 22 and is connected to a drive part 411. The drive part 411 is provided with outwardly extending drive baffles 412 on both sides. The mounting cavity is provided with a telescopic rod 413 that is linked with the drive baffles 412. The telescopic rod 413 is provided with a first slot 414 and a second slot 415. When the drive baffles 412 engage with the first slot 414, the bottom of the telescopic rod 413 extends to the outside of the mounting cavity 22 and engages with the drive rod 41.

[0024] This technical solution utilizes two handles joined together to form a single structure, significantly improving load-bearing strength and stability compared to a single-layer handle structure, thus avoiding the risk of handle breakage due to fragility during handling. The locking component 4 securely locks the fixed shaft 31, preventing the handle from loosening or separating during transport and enhancing carrying safety. By incorporating a drive unit 411 within the mounting cavity 22, internal transmission and locking functions are achieved without increasing external volume, ensuring a compact structure and preventing external parts from affecting the aesthetics of the packaging. The multi-slot design of the telescopic rod 413 allows the drive stop bar 412 to be locked or unlocked with the fixed shaft 31 at different positions, enhancing the structure's flexibility and applicability while improving the handle's locking stability.

[0025] The first slot 414 and the second slot 415 are arranged in a wave-like shape, and a connecting slope 416 is provided between the first slot 414 and the second slot 415. The drive bar 412 rotates and slides between the first slot 414 and the second slot 415 through the connecting slope 416 to switch and engage with one of the slots.

[0026] This technical solution, by designing the slots in a wave-like shape, creates a stable stop position after the drive stop bar 412 is engaged, preventing the telescopic rod 413 from accidentally slipping under force and improving the reliability of the locking mechanism. The connecting ramp 416 allows the drive stop bar 412 to slide smoothly along the ramp during operation, achieving smooth switching between slots and avoiding operational jamming that could affect the user experience.

[0027] The telescopic rod 413 includes a rod head 42, a first slot 414 and a second slot 415 are provided on the rod head 42, a rod body 43 is provided at the bottom of the rod head 42, and a spring 44 is sleeved on the rod body 43. One end of the spring 44 is fixedly connected to the bottom of the mounting cavity 22, and the other end abuts against the bottom of the rod head 42.

[0028] This technical solution, by setting the first slot 414 and the second slot 415 on the rod head 42 of the telescopic rod 413, can centrally achieve the engagement with the drive stop bar 412, with a compact structure, which facilitates the stable operation of the locking mechanism.

[0029] The bottom of the mounting cavity 22 is connected to the mounting channel 23, and the bottom of the rod 43 extends out of the mounting channel 23 when the drive stop bar 412 is engaged with the first slot 414.

[0030] This technical solution involves installing a spring 44 on the rod 43, enabling the telescopic rod 413 to automatically reset when pushed or released by the drive stop bar 412, thus improving operational convenience and structural reliability. One end of the spring 44 is fixed to the bottom of the mounting cavity 22, while the other end abuts against the bottom of the rod head 42, ensuring that the telescopic rod 413 is always subjected to elastic preload when under force, thereby preventing the locking mechanism from loosening and enhancing the stability and durability of the locking mechanism.

[0031] The bottom of the rod body 43 is provided with a first locking groove 45, and the fixed shaft 31 is provided with a second locking groove 32 for engaging with the first locking groove 45.

[0032] This technical solution utilizes a locking groove between the rod 43 and the fixed shaft 31 to create a reliable meshing connection during locking, further enhancing the handle's stability. The meshing of the locking groove effectively prevents the fixed shaft 31 from rotating or loosening, ensuring the handle remains stable even under heavy loads and preventing accidental cracking or falling of the packaging box due to structural loosening.
