Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a two-way push-pull packaging box. Background Technology

[0002] With the development of society and industry, the requirements and craftsmanship of packaging design are becoming increasingly higher. Compared with traditional packaging boxes, premium boxes have a more advantageous appearance and better display function. The combination of various high-quality materials can better highlight the product's quality, taste and grade, while also providing better protection for the product. They are the best choice for valuable goods or gifts.

[0003] A search revealed that Chinese utility model patent application CN202121331193.0 discloses a packaging box, including a box body, a lid, a first sliding storage box, and a second sliding storage box. One side of the lid is rotatably connected to one side of the box body. The first and second sliding storage boxes are slidably connected to the box body in opposite directions. The second sliding storage box is located on the side of the first sliding storage box closest to the lid. This packaging box allows for the display of the stored items.

[0004] For example, Chinese utility model patent application CN202122906948.1 discloses a push-pull packaging box, including a box body and a movable cover. The push-pull packaging box also includes: a locking structure, partly disposed on the movable cover and partly disposed on the box body, which can slide relative to the box body to lock the movable cover and the box body or release the lock between the movable cover and the box body. The movable cover is provided with a first sliding groove and a sliding hole communicating with the first sliding groove. The locking structure includes: a locking block slidably assembled in the first sliding groove; a connector fixedly connected to the locking block at one end; a protruding limiting part disposed on the top of one side of the box body, the protruding limiting part being provided with an insertion hole for the locking block to pass through; and a pushing member disposed on the outside of the movable cover and on the connector away from the locking block. Using the above technical solution, the movable cover is placed on the box body, and the locking structure stabilizes the movable cover on the box body, preventing the movable cover from being pulled out of the box body.

[0005] While the existing packaging boxes can meet basic usage needs, they require opening each box separately when multiple items need to be retrieved, and cannot achieve bidirectional pull-out, which is time-consuming, labor-intensive, inefficient, inconvenient to use, and has a relatively complex structure and high production cost. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a two-way push-pull packaging box in view of the above-mentioned defects of the prior art. By passing several mechanism layer connecting films through the gray plate of the mechanism layer, and the mechanism layer connecting films are respectively connected to the left side of the upper inner box and the right side of the lower inner box, the lower inner box can be moved in the opposite direction when the upper inner box is pulled out, so as to realize two-way pull-out, which saves time and effort, has high efficiency, is more convenient to use, and has a simpler structure and lower manufacturing cost.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0008] A two-way push-pull packaging box includes an outer box, an upper inner box, a lower inner box, and a mechanism layer gray board. The upper inner box and the lower inner box are slidably disposed inside the outer box from top to bottom. The mechanism layer gray board is located between the upper inner box and the lower inner box. A plurality of mechanism layer connecting films are inserted through the mechanism layer gray board. The mechanism layer connecting films are respectively connected to the left side of the upper inner box and the right side of the lower inner box. An upper inner support plate and a lower inner support plate are detachably installed on the upper inner box and the lower inner box, respectively.

[0009] Preferably, the gray plate of the mechanism layer has a first connecting membrane through hole and a second connecting membrane through hole for the mechanism layer connecting membrane to pass through.

[0010] Preferably, the upper left end of the outer box has an upper through hole for the upper inner box to pass through, and the lower right end of the outer box has a lower through hole for the lower inner box to pass through.

[0011] Preferably, the mechanism layer connecting film includes a first mechanism layer connecting film and a second mechanism layer connecting film. The first mechanism layer connecting film passes through the through hole of the first connecting film and is connected to the upper inner box and the lower inner box respectively. The second mechanism layer connecting film passes through the through hole of the second connecting film and is connected to the upper inner box and the lower inner box respectively.

[0012] Preferably, the upper inner support plate has an upper placement groove, and the lower inner support plate has a lower placement groove.

[0013] Preferably, a pull-out strap is provided on the right side of the upper inner box and the left side of the lower inner box.

[0014] The present invention provides a bidirectional push-pull packaging box with the following advantages: The upper and lower inner boxes of the bidirectional push-pull packaging box are slidably arranged inside the outer box from top to bottom. A mechanism layer gray plate is located between the upper and lower inner boxes. Several mechanism layer connecting films are threaded through the mechanism layer gray plate, connecting to the left side of the upper inner box and the right side of the lower inner box respectively. An upper inner support plate and a lower inner support plate are detachably installed on the upper and lower inner boxes respectively. By setting the mechanism layer connecting films to connect the left side of the upper inner box and the lower inner box respectively, the lower inner box moves in the opposite direction when the upper inner box is pulled out, and the lower inner box is pushed out from the other side when the upper inner box is pulled out. Conversely, when the upper inner box is pushed in, the lower inner box retracts, achieving bidirectional pull-out. This saves time and effort, is highly efficient, more convenient to use, and has a simpler structure and lower manufacturing cost. Attached Figure Description

[0022] like Figure 1-3 As shown, the two-way push-pull packaging box includes an outer box 1, an upper inner box 2, a lower inner box 3, and a mechanism layer gray board 4. The upper inner box 2 and the lower inner box 3 are slidably disposed within the outer box 1 from top to bottom. The mechanism layer gray board 4 is located between the upper inner box 2 and the lower inner box 3. Several mechanism layer connecting films are threaded through the mechanism layer gray board 4, and these connecting films are respectively connected to the left side of the upper inner box 2 and the right side of the lower inner box 3. An upper inner support plate 5 and a lower inner support plate 6 are detachably installed on the upper inner box 2 and the lower inner box 3, respectively. It is understood that the outer box 1, the upper inner box 2, the lower inner box 3, and the mechanism layer gray board 4 are all made of paper material, while the mechanism layer connecting films are made of plastic.

[0023] Specifically, the gray plate 4 of the mechanism layer has a first connecting membrane through hole 7 and a second connecting membrane through hole 8 for the mechanism layer connecting membrane to pass through; the upper left end of the outer box 1 has an upper through hole 9 for the upper inner box 2 to pass through, and the lower right end of the outer box 1 has a lower through hole 10 for the lower inner box 3 to pass through; the mechanism layer connecting membrane includes a first mechanism layer connecting membrane 11 and a second mechanism layer connecting membrane 12, the first mechanism layer connecting membrane 11 passes through the first connecting membrane through hole 7 and connects to the upper inner box 2 and the lower inner box 3 respectively, and the second mechanism layer connecting membrane 12 passes through the second connecting membrane through hole 8 and connects to the upper inner box 2 and the lower inner box 3 respectively; the upper inner support plate 5 has an upper placement groove 13, and the lower inner support plate 6 has a lower placement groove 14; the right side of the upper inner box 2 and the left side of the lower inner box 3 are both provided with pull straps 15.

[0024] Understandably, this utility model has a reasonable design and unique structure. By setting a connecting membrane in the mechanism layer to connect the left side of the upper inner box 2 and the lower inner box 3 respectively, the lower inner box 3 can be moved in the opposite direction when the upper inner box 2 is pulled out. When the upper inner box 2 is pulled out, the lower inner box 3 is pushed out from the other side. When the upper inner box 2 is pushed in, the lower inner box 3 is also retracted. This achieves bidirectional pulling, which saves time and effort, is highly efficient, more convenient to use, and has a relatively simple structure and low manufacturing cost.
