For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0053] In addition, the terms "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified and limited.
[0054] As shown in Figures 1 to 4 The utility model provides a folding box, mainly includes base 2 and two pairs of opposite side plate 1, side plate 1 is hinged with base 2.
[0055] As an example, the typical shape of folding box is cuboid, and the side plate 1 includes a pair of long plates 11 and a pair of short plates 12. The bottom of the long plate 11 and the short plate 12 is provided with a hinge part 112, and the bottom plate is provided with a hinge groove. The hinge part 112 and the hinge groove cooperate with each other to realize the pivotable connection between the base 2 and the side plate 1.
[0056] As an example, the bottom of the long plate 11 corresponds to the first hinge groove 21 on the base 2, and the bottom of the short plate 12 corresponds to the second hinge groove 22. The height of the first hinge groove 21 is lower than the height of the second hinge groove 22. After unlocking, the two long plates 11 are folded inward by rotating around the hinge part 112 in sequence, and then the two short plates 12 are folded inward in sequence, realizing the rapid folding of the folding box. As a preferred embodiment, the height difference between the first hinge groove 21 and the second hinge groove 22 is greater than or equal to the thickness of the long plate 11, so that the folded box is more flat.
[0057] Specifically, the side plate 1 is provided with a locking mechanism for locking and unlocking adjacent side plates 1. The locking mechanism includes a locking rod 3, which is transversely arranged in a pair of side plates 1. In this specification, the locking rod 3 is arranged in the long plate 11 as an example. The locking rod 3 transversely penetrating the side plate 1 not only realizes the synchronous unlocking of the adjacent side plate 1 by single-handed pressing, but also enhances the strength of the side plate 1.
[0058] The adjacent long plate 11 and short plate 12 are engaged with each other through the interlocking structure. The interlocking structure can adopt the existing scheme commonly used in the market, and its specific structure is not limited. Further, the adjacent long plate 11 and short plate 12 are locked and unlocked by the locking rod 3. The locking rod 3 includes an operating section 31 in the middle and a connecting section 32 connected to both ends of the operating section 31. The connecting section 32 has a lock tongue 322 at the front end, and a lock hole is arranged at the corresponding position of the adjacent short plate 12.
[0059] Furthermore, the top of the operating section 31 is provided with a first elastic element 311, and the bottom part of the operating section 31 extends out of the unlocking port 121 on the surface of the long plate 11 to form an unlocking button. The long plate 11 is provided with an installation groove that matches the shape of the locking rod 3. Specifically, both ends of the operating section 31 include a first connecting part 312, and the end of the first connecting part 312 is provided with a connecting protrusion 3121. The inner side of the connecting protrusion 3121 is a ramp. The rear end of the connecting section 32 is provided with a second connecting part 323 that is opposite to and cooperates with the first connecting part 312. The rear end of the second connecting part 323 is provided with a second elastic element 3232, and the second connecting part 323 is provided with a slide 3231 that cooperates with the connecting protrusion 3121.
[0060] When the operator presses the unlock button, the middle part of the operating section 31 of the locking lever 3 deforms upward, the two ends of the operating section 31 retract inward, and a slight inward rotation occurs. The connecting protrusion 3121 of the first connecting part 312 simultaneously pulls the connecting sections 32 on both sides inward along the mounting groove. Finally, the locking tongue 322 at the front end of the connecting section 32 retracts inward and disengages from the lock opening 121, thus unlocking the device.
[0061] After the operator releases the unlock button, the operating section 31 and the connecting section 32 are reset under the drive of the elasticity of the locking rod 3 and the first elastic element 311. The locking tongue 322 at the front end of the connecting section 32 is pushed out and enters the lock slot 121 to achieve locking.
[0062] During the unlocking and locking process, the second elastic element 3232 acts as a buffer and provides auxiliary elasticity between the first connecting part 312 and the second connecting part 323. The connecting protrusion 3121, the inclined platform on its inner side, and the slide 3231 that cooperates with the connecting protrusion 3121 in the second connecting part 323 can provide room for the slight rotation and relative displacement of the operating section 31, preventing the locking rod 3 from breaking.
[0063] Furthermore, the first elastic element 311 includes two symmetrically arranged arc-shaped elastic arms, and the front end of the elastic arm is provided with a wear-resistant protrusion 3111 to improve the service life of the first elastic element 311.
[0064] Furthermore, a limiting slider 321 is provided on the connecting section 32, and a limiting groove 111 is opened at the corresponding position on the outer surface of the side plate 1 where the locking lever 3 is located. The length of the limiting groove 111 matches the displacement value of the locking tongue 322 required during the unlocking and locking process. It should be noted that the displacement value of the locking tongue 322 required during the unlocking and locking process should be less than or equal to the maximum displacement value that the connecting section 32 can achieve in the horizontal direction. This can constrain the deformation amplitude of the locking lever 3, prevent excessive pressing from causing mechanical jamming or structural deformation, and improve the reliability and durability of the locking action.
[0065] Furthermore, the base 2 is equipped with an IoT chip slot 23, supporting rapid installation and maintenance of RFID / NFC chips. The opening of the IoT chip slot 23 is detachably covered by a top cover 24, which has a claw 242 and a first connection hole 241. The IoT chip slot 23 is correspondingly equipped with a slot 232 and a second connection hole 231. The top cover 24 and the IoT chip slot 23 are doubly fixed by a combination of snap-fit and screws.
[0066] Furthermore, the bottom surface of the base 2 is provided with anti-slip grooves 25, which increase the stacking friction coefficient through multi-directional grooves to prevent the box from sliding during transportation.
[0067] Furthermore, the outer surface of the side panel 1 is equipped with a detachable handle 4, which adopts a plug-in design to balance the convenience of handling and the flatness after folding.
[0068] By adopting the above technical solution, the folding box provided by this utility model has the following advantages compared with the prior art:
[0069] (1) The present invention provides a folding box that integrates an operating section, an elastic element, and an unlocking button through a locking rod that runs horizontally through the side panel, enabling simultaneous unlocking of adjacent side panels with a single hand press. When the unlocking button is pressed, the overall deformation of the locking rod causes the locking tongues on both sides to retract synchronously, releasing the mechanical constraint on the adjacent side panels; after releasing the pressure, the rebound force of the first elastic element drives the locking rod to automatically reset, ensuring that the box is automatically locked after folding. This design integrates the traditional step-by-step independent locks into a linkage structure, significantly simplifying the operation process and avoiding the risk of missing locks, and is especially suitable for the rapid folding requirements in automated logistics scenarios.
[0070] (2) The folding box provided by this utility model adopts a symmetrical arc-shaped elastic arm as the first elastic element. The symmetrical deformation of the double arc-shaped arm disperses stress concentration and improves the fatigue resistance of the elastic element. A wear-resistant protrusion is added to the front end of the elastic arm, which forms rolling friction with the inner wall of the mounting groove to replace the traditional sliding friction, reducing wear during long-term use and extending the service life of the locking mechanism. This structure ensures elasticity while avoiding the defects of traditional springs or sheet springs that are prone to deformation and breakage.
[0071] (3) The folding box provided by this utility model uses a ramp slide and a second elastic element to connect the locking rod. By connecting the ramp and the ramp slope, the locking tongue extension and retraction trajectory is accurately controllable. The fitting design of the limit slider and the side plate limit groove restricts the deformation of the locking rod, prevents excessive pressing from causing mechanical jamming or structural deformation, and improves the reliability and durability of the locking action.
[0072] (4) The present invention provides a folding box with an IoT chip slot in the base, which supports the rapid installation and maintenance of RFID / NFC chips and meets the needs of cargo tracking.
