Description

Technical Field

[0001] This utility model relates to the field of packaging boxes, and more particularly to a packaging box that is easy to open. Background Technology

[0002] Advances in manufacturing have driven the widespread use of packaging boxes, while also placing higher demands on their performance, especially in industries like beverages where increasingly stringent requirements for airtight packaging are needed. However, common beverage packaging boxes on the market have significant shortcomings in terms of locking reliability and user experience. Firstly, the widely used snap-on sealing structure itself has inherent flaws; not only is the sealing effect unsatisfactory, but it is also prone to unlocking due to accidental collisions during handling, posing a safety hazard. Secondly, this design also falls short in terms of user experience and economy: opening is often laborious, and many snaps are for single use, reducing convenience and increasing per-use costs due to non-reusability, which is detrimental to environmental protection and large-scale application. These design flaws ultimately lead to practical problems such as packaging boxes being easily opened accidentally and damaged, hindering the improvement of product performance. Utility Model Content

[0003] The present invention aims to provide a packaging box that is easy to open, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An easy-to-open packaging box includes a box body and a lid. The box body has an insertion hole, and the lid has a locking groove. A rotating shaft is rotatably connected to the inner wall of the locking groove. A turntable is connected to the rotating shaft. The turntable has a driving groove. An insert plate is slidably connected to the inner wall of the locking groove. The insert plate is slidably connected to the inner wall of the insertion hole. A connecting rod is connected to the insert plate. The connecting rod is slidably connected to the inner wall of the driving groove. A handle is connected to the rotating shaft. A limit structure is connected to the inner wall of the locking groove.

[0006] The limiting structure includes a pawl, which is rotatably connected to the inner wall of the lock groove. A ratchet is connected to the rotating shaft, and the pawl and the ratchet cooperate with each other. A spring is connected to both the pawl and the inner wall of the lock groove.

[0007] Preferably, the pawl is connected to an unlocking rod, the cover has an unlocking hole communicating with the lock groove, and the unlocking rod is slidably connected to the side wall of the unlocking hole.

[0008] Preferably, the pawl and the inner wall of the locking groove are rotatably connected to a telescopic rod.

[0009] Preferably, the cover has a slot, and the box body is slidably connected to the inner wall of the slot.

[0010] Preferably, the box body is connected to a handle.

[0011] Preferably, the handle is provided with a friction part.

[0012] Preferably, a gasket is connected to the inner wall of the slot.

[0013] Preferably, the drive groove is arc-shaped.

[0014] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0015] (1) This utility model constitutes a highly efficient transmission and locking mechanism by setting up a turntable driven by a handle, and a connecting rod and a plate that cooperate with the drive groove on the turntable. The user only needs to slightly rotate the handle to push the connecting rod through the drive groove, thereby controlling the plate to smoothly insert or withdraw from the insertion hole of the box. This mechanism converts rotational motion into linear motion, realizing easy locking and opening of the packaging box, effectively overcoming the defects of traditional buckle structures that are difficult to open and easily damaged, and significantly improving the convenience of operation and user experience.

[0016] (2) This utility model achieves a one-way self-locking function for the rotating shaft and turntable by adopting a limiting structure including a ratchet and a pawl, supplemented by a spring to provide continuous meshing force. This structure can reliably prevent the turntable from reversing during vibration or accidental collision, thereby ensuring that the insert plate is always in the locked working position, enhancing the reliability and security of the packaging box's locked state. At the same time, with the independently operated unlocking lever, the self-locking can be easily released when needed, achieving a balance between the reliability of locking and the convenience of opening.

[0017] (3) This utility model provides a slot on the lid, allowing the box to be embedded within it, thus achieving initial positioning and sealing. This structure not only improves the alignment accuracy of the lid and box when they are closed, ensuring that the insert plate can be smoothly aligned with the insertion hole, but also effectively enhances the overall sealing performance of the packaging box by increasing the additional contact surface. This pre-positioning design makes the locking process smoother and further optimizes the user experience of the product. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0023] like Figures 1 to 3 The illustration shows an easy-to-open packaging box, comprising a box body 1 and a lid 2. (As shown) Figure 1 As shown, each side panel of the box body 1 has an insertion hole 4. Figure 2 As shown, the cover 2 has a locking groove 9, and a rotating shaft 19 is rotatably connected to the inner wall of the locking groove 9. The rotating shaft 19 is connected to a turntable 11. The turntable 11 has four arc-shaped drive grooves 12. Four insert plates 10 are slidably connected to the inner wall of the locking groove 9. The outer side of the insert plate 10 is slidably connected to the inner wall of the insertion hole 4 to achieve locking. The insert plate 10 is connected to a connecting rod 13, which is slidably connected to the inner wall of the drive groove 12. Rotating the rotating shaft 19 drives the turntable 11 to rotate. The arc-shaped drive grooves 12 on the turntable 11 will squeeze or pull the connecting rod 13 that is slidably engaged with it. Since the other end of the connecting rod 13 is fixed to the insert plate 10 and its movement trajectory is constrained by the inner wall of the locking groove 9, the force of the drive groove 12 on the connecting rod 13 is converted into a precise linear movement that pushes the insert plate 10 to extend linearly and insert into the insertion hole 4 of the box 1, or pulls the insert plate 10 to retract linearly and withdraw from the insertion hole 4. This realizes the locking and opening of the packaging box through rotation operation.

[0024] like Figure 1 As shown, a handle 5 is connected to the top of the rotating shaft 19, and the handle 5 is provided with a friction part 6 for easy screwing. Figure 2 As shown, a limiting structure is connected to the inner wall of the locking groove 9. The limiting structure includes a pawl 15 rotatably connected to the inner wall of the locking groove 9, and a ratchet 14 connected to the rotating shaft 19. The pawl 15 and the ratchet 14 cooperate with each other. The pawl 15 and the inner wall of the locking groove 9 are connected to a spring 16. The ratchet 14 and the pawl 15 mechanism constitute a one-way self-locking function. Under the action of the spring 16, the pawl 15 will lock the ratchet 14 to prevent it from reversing, thereby ensuring that the packaging box will not be accidentally released during transportation.

[0025] like Figure 2 As shown, an unlocking lever 8 is connected to the top of the pawl 15. Figure 1 As shown, the cover 2 has an unlocking hole 7 that communicates with the lock groove 9. The unlocking rod 8 is slidably connected to the side wall of the unlocking hole 7. By moving the unlocking rod 8, the pawl 15 can disengage from the ratchet 14, thereby releasing the self-locking mechanism and enabling easy opening. Figure 2As shown, the pawl 15 and the inner wall of the locking groove 9 are rotatably connected to a telescopic rod 17, which is used to enhance the stability of the pawl 15 during operation.

[0026] like Figure 3 As shown, the lid 2 has a slot 18, and the box body 1 is slidably connected to the inner wall of the slot 18 for initial positioning and sealing when the lid is closed. A gasket is connected to the inner wall of the slot 18 to enhance the sealing effect. Figure 1 As shown, the box 1 is connected to a handle 3 for easy handling.

[0027] The specific implementation process is as follows:

[0028] When the packaging box needs to be locked, first align the slot 18 of the lid 2 with the box body 1 and fasten it, so that the upper edge of the box body 1 is embedded in the slot 18 to complete the initial positioning and sealing. Then, rotate the handle 5 clockwise. The handle 5 drives the rotating shaft 19 and the turntable 11 fixed on it to rotate synchronously. The arc-shaped drive groove 12 on the turntable 11 rotates accordingly and presses the connecting rod 13 that slides with it, forcing the connecting rod 13 to drive the insert plate 10 to move outward in a straight line along the inner wall of the locking groove 9 until the insert plate 10 is fully inserted into the insertion hole 4 of the box body 1 to achieve a firm lock. During the process, the ratchet 14, which rotates synchronously with the rotating shaft 19, will pass over the pawl 15 and be locked by the pawl 15 under the action of the spring 16, forming a reliable one-way self-locking, ensuring that the locked state will not be accidentally loosened during transportation; when it is necessary to open, simply push the unlocking rod 8 inward through the unlocking hole 7, so that the pawl 15 overcomes the elastic force of the spring 16 and disengages from the ratchet 14, and the handle 5 can be easily rotated counterclockwise. At this time, the drive groove 12 pulls the connecting rod 13 and the insert plate 10 in the opposite direction to retract inward, so that the insert plate 10 exits the insertion hole 4, thereby smoothly opening the cover 2.

[0029] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
