Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a packaging box that is easy to open. Background Technology

[0002] Packaging boxes are boxes used to package products. Common types of packaging boxes include hinged box boxes, drawer boxes, and corrugated boxes. Among hinged box types, especially those where the top lid can completely detach from the bottom, the top lid usually slides upwards to separate from the bottom. The disadvantage of this structure is:

[0003] 1. The top cover needs to be held with both hands from the side wall to separate it from the bottom box, which reduces the flexibility and convenience of opening.

[0004] 2. The free sliding connection between the top cover and the bottom box means that the packaging box can only be carried with the top cover facing upwards, requiring the user to hold it with both hands or clamp it between one arm and body, making it inconvenient to move and carry.

[0005] To address the above issues, a packaging box that is easy to open is proposed. Utility Model Content

[0006] The main purpose of this utility model is to provide a packaging box that is easy to open, thus solving the problems mentioned in the background art.

[0007] The objective of this utility model can be achieved by adopting the following technical solution:

[0008] An easy-to-open packaging box includes an upper lid and an inner box. The upper lid has an opening mechanism in its inner wall, and the inner box has non-through latching holes on its four corner walls.

[0009] The opening mechanism includes a rotating shaft rotatably connected to the top of the upper cover. A rotating handle is fitted on one end of the rotating shaft. A reel is fixed on the outer wall of the middle section of the rotating shaft. A spring box is fitted on the bottom of the rotating shaft. A winding thread is fixed on the outer wall of the reel. A guide tube is fitted on the outer wall of the winding thread. A locking mechanism is fixed at one end of the bottom of the guide tube.

[0010] Furthermore, a first handle is detachably provided on the outer side wall of the upper box cover, and a second handle is hinged to the top of the upper box cover. A magnetic snap embedded in the upper box cover is magnetically connected directly below the second handle.

[0011] Furthermore, the locking mechanism includes a fixing rod fixed to the bottom of the inner cavity of the upper cover, and a telescopic sleeve is fixedly connected to the top of the fixing rod, with the conduit communicating with the inside of the telescopic sleeve.

[0012] Furthermore, a return spring is clamped at one end of the telescopic sleeve, and a retaining protrusion is connected to the outside end of the return spring and slidably connected to the inside of the telescopic spring. The inner side wall of the retaining protrusion is fixedly connected to the winding wire. Through guide holes are provided on the four internal corner walls of the upper cover, and the retaining protrusion is slidably connected to the guide holes.

[0013] Furthermore, one outer end of the locking protrusion is a hemispherical structure, the locking hole is a spherical hole, and the locking protrusion is adapted to engage with the locking hole.

[0014] Furthermore, the bottom of the spring box is fixed to the bottom of the inner cavity of the upper cover, a spiral spring is embedded in the spring box, the bottom of the rotating shaft extends into the spring box and is fixedly connected to the core of the spiral spring, and the rotating shaft is also rotatably connected to the spring box.

[0029] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0030] like Figures 1-8 As shown, this embodiment provides an easy-to-open packaging box, including an upper cover 1 and an inner box 4. An opening mechanism 3 is provided in the inner wall of the upper cover 1, and non-through-hole clips 401 are provided on the four external corner walls of the inner box 4. The opening mechanism 3 includes a rotating shaft 301a that is rotatably connected to the top of the upper cover 1. A rotating handle 301 is sleeved on one end of the rotating shaft 301a. A reel 302 is fixed on the outer wall of the middle section of the rotating shaft 301a. A spring box 306 is installed at the bottom of the rotating shaft 301a. A winding thread 303 is fixed on the outer wall of the reel 302. A guide tube 304 is sleeved on the outer wall of the winding thread 303. A locking mechanism 305 is fixed at one bottom end of the guide tube 304.

[0031] In the above structure, the upper cover 1 and the inner box 4 are both made of cardboard. The upper cover 1 is 3cm thick and the inner box 4 is 1.5cm thick. The rotating handle 301, the rotating shaft 301a, and the reel 302 are all made of plastic. When the reel 302 drives the line 303 to rotate, the winding length is 0.5-1cm. The line 303 slides along the guide tube 304 and is made of transparent fishing line material.

[0032] A first handle 101 is detachably provided on the outer side wall of the upper box cover 1. A second handle 102 is hinged to the top of the upper box cover 1. A magnetic snap 103 embedded in the upper box cover 1 is magnetically connected directly below the second handle 102. When the first handle 101 is not in use, it can be stored by magnetically attaching to the magnetic snap 103. Both handles can be operated with one hand, which solves the drawback of traditional top and bottom box packaging boxes that require two hands to carry.

[0033] The locking mechanism 305 includes a fixing rod 305c fixed to the bottom of the inner cavity of the upper cover 1. A telescopic sleeve 305a is fixedly connected to the top of the fixing rod 305c. The conduit 304 communicates with the inside of the telescopic sleeve 305a. The fixing rod 305c supports and fixes the telescopic sleeve 305a.

[0034] A return spring 305d is clamped inside one end of the telescopic sleeve 305a. The outer end of the return spring 305d is connected to a locking protrusion 305b that is slidably connected to the inside of the telescopic spring. The inner side wall of the locking protrusion 305b is fixedly connected to the winding cable 303. The four internal corner walls of the upper cover 1 are provided with through guide holes 104. The locking protrusion 305b is slidably connected to the guide holes 104. In the initial state, the return spring 305d pushes the locking protrusion 305b out of the telescopic sleeve 305a. When the winding cable 303 pulls, it retracts back. When the box is closed normally, the locking protrusion 305b can also retract back to the telescopic sleeve 305a by squeezing.

[0035] One end of the snap-fit ​​protrusion 305b is a hemispherical structure, and the snap-fit ​​hole 401 is a spherical hole. The snap-fit ​​protrusion 305b and the snap-fit ​​hole 401 are fitted and snapped together. The spherical structure can improve the smoothness of the snap-fit ​​protrusion 305b and the snap-fit ​​hole 401.

[0036] The bottom of the spring box 306 is fixed to the bottom of the inner cavity of the upper cover 1. The spring box 306 contains a spiral spring 306a. The bottom of the rotating shaft 301a extends into the spring box 306 and is fixedly connected to the core of the spiral spring 306a. The rotating shaft 301a is also rotatably connected to the spring box 306. When the spiral spring 306a is reset, it releases the reel 302 and the winding 303. The winding 303 is then pushed back by the compressed reset spring 305d to achieve tension.

[0037] The bottom of the inner box 4 is glued with a box bottom plate 2 that is aligned with the outer periphery of the upper box cover 1.

[0038] The working principle of this device is as follows:

[0039] When the upper lid 1 and the inner box 4 are fastened together, the upper lid 1 slides down directly aligned with the outer wall of the inner box 4. The locking protrusion 305b slides against the outer wall of the inner box 4 and is squeezed into the telescopic sleeve 305a, which in turn squeezes the return spring 305d. When the upper lid 1 contacts the bottom plate 2, the locking protrusion 305b aligns with the locking hole 401 and pops out into the locking hole 401, thus locking the four corners of the upper lid 1 with the inner box 4 and maintaining the overall stability of the packaging box. At this time, the packaging box can be carried vertically by the second handle 102 or horizontally by the first handle 101, thereby improving the carrying flexibility of the top and bottom lid packaging box.

[0040] When opening the upper box cover 1 and the inner box 4, the box bottom plate 2 is placed on a flat surface. Rotating the rotating handle 301 causes the rotating handle 301 to drive the reel 302 to wind up the winding cable 303 via the rotating shaft 301a, and compress the spiral spring 306a in the spring box 306. The winding cable 303 pulls the locking protrusion 305b in the telescopic sleeve 305a along the guide tube 304 and enters the telescopic sleeve 305a, disengaging from the locking hole 401, so that the upper box cover 1 and the inner box 4 are separated, and the upper box cover 1 can be slid upward to quickly open the packaging box.

[0041] With the above structure, rotating the handle 301 drives the reel 302 to wind up the cable 303. The cable 303 pulls the locking protrusion 305b out of the locking hole 401, thus separating the upper cover 1 from the inner box 4. The upper cover 1 can be lifted with one hand by rotating the handle 301, realizing quick opening of the packaging box and improving the operational flexibility of the packaging box. By setting the locking mechanism 305, when the upper cover 1 and the inner box 4 are fastened, the locking protrusion 305b enters the telescopic sleeve 305a by the compression of the outer wall of the inner box 4. When it moves to the locking hole 401, the locking protrusion 305b enters the locking hole 401, realizing the locking of the upper cover 1 and the inner box 4. The packaging box can be carried and moved horizontally and vertically with one hand by the first handle 101 and the second handle 102, which is conducive to the movement and carrying of the packaging box.
