Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a packaging box that can be easily folded and stored. Background Technology

[0002] Foldable storage boxes are packaging containers that can be folded and spliced ​​to change their shape. When not in use, they can be folded into a flat state to save storage space. When in use, they are unfolded and fixed according to the preset structure to form a box with a certain capacity for storing and protecting various items. After use, they can be folded back for storage. The operation is convenient. The packaging box is mainly composed of a frame, a support base, folding side panels, limiting side panels, and a top cover. When in use, the folding side panels are unfolded, and the limiting side panels are engaged between the two folding side panels. When storing, first rotate the limiting side panels upward, then fold the folding side panels. After folding, the frame is attached to the top of the support base for storage.

[0003] When the packaging box is in use, it is only fixed between the two folding side panels by a limiting side plate. When the outer side of the limiting side plate is impacted, the limiting side plate is prone to rotate between the two folding side panels, which leads to a decrease in the support stability of the two folding side panels. Therefore, this application provides a packaging box that can be easily folded and stored to meet the needs. Utility Model Content

[0004] This utility model provides a packaging box that can be easily folded and stored to solve the problem that when the outer side of the limiting side plate is impacted, the limiting side plate is prone to rotating between the two folding side plates, which leads to a decrease in the support stability of the two folding side plates.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A conveniently foldable and storable packaging box includes a frame and a support base. Folding side panels are rotatably connected to the bottom of each of the two long sides of the frame, and limiting side panels are rotatably connected to the bottom of each of the two short sides of the frame. The folding side panels are rotatably connected to the top of the inner wall of the support base, and the limiting side panels abut against the top of the inner wall of the support base. The box also includes:

[0007] The fixing mechanism includes two L-shaped fixing members rotatably connected to the outside of the short side of the frame. The two L-shaped fixing members are symmetrically arranged about the middle of the frame. The top of the horizontal part of the L-shaped fixing member is integrally formed with a snap-fit ​​part. A fixing hole is opened on the surface of the limiting side plate.

[0008] In use, the horizontal part of the L-shaped fastener passes through the fixing hole and is locked onto the inside of the limiting side plate.

[0009] Preferably, a mounting base is fixed to the outer side of the short side of the frame, a round rod is fixed to the inner wall of the mounting base, an L-shaped fastener is movably sleeved on the surface of the round rod, and two limiting rings are fixedly sleeved on the surface of the round rod, with the two limiting rings fitting against both sides of the L-shaped fastener.

[0010] Preferably, the bottom of the L-shaped fastener is fixed with an inclined plate, and the bottom of the inclined plate is inclined outward.

[0011] Preferably, the bottom of the inclined plate has an integrally formed protrusion on the side near the limiting side plate, and the protrusion is arc-shaped.

[0012] Preferably, the surface of the vertical part of the L-shaped fastener is provided with a curved groove.

[0013] Preferably, the inner wall of the curved groove has arc-shaped surfaces at the top and bottom.

[0014] Preferably, a second fixing hole is provided on the outer side of the short side of the support base. After the folding side plate is folded, the locking part of the horizontal part of the L-shaped fixing member passes through the second fixing hole and is locked onto the inner side of the support base.

[0015] Preferably, the vertical portion of the L-shaped fastener is integrally formed with anti-slip stripes.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above solution, by setting an L-shaped fastener, a snap-fit ​​part, and a fixing hole, when in use, the snap-fit ​​part of the horizontal part of the L-shaped fastener passes through the fixing hole and snaps onto the inside of the limiting side plate. The snap-fit ​​part limits the limiting side plate from rotating when it is impacted, thereby ensuring the stable limiting of the folding side plate by the limiting side plate.

[0018] By setting up a mounting base, the mounting base provides a mounting foundation for the round rod. Secondly, when handling the packaging box, the mounting base can act as a handle, making it convenient for personnel to move the packaging box.

[0019] By setting the second fixing hole, after the folding side plate is folded, the locking part of the horizontal part of the L-shaped fastener passes through the second fixing hole and locks into the inside of the support base. This can prevent the frame from separating from the support base when the whole is folded, thus improving the stability during transportation.

[0020] By incorporating a ramp and a protrusion, when it is necessary to remove the locking part from either the first or second fixing hole, the finger is locked onto the ramp, the thumb rests on the vertical part of the L-shaped fastener, and the ramp is pulled outward. The ramp will cause the horizontal end of the L-shaped fastener to move downward, thereby disengaging the locking part of the L-shaped fastener from the contact position. Then, the horizontal part of the L-shaped fastener can be rotated out of either the first or second fixing hole. The ramp provides operating space for the fingers, making operation more effortless and convenient. The protrusion on the ramp increases the contact area between the finger and the ramp, preventing the finger from disengaging from the ramp and improving operational stability.

[0021] By setting curved grooves and arc-shaped surfaces, the vertical part of the L-shaped fastener bends during the process of removing the snap-fit ​​part from the fixing hole one or fixing hole two. The curved grooves make bending easier, and the arc-shaped surfaces prevent stress concentration at the top and bottom of the inner wall of the curved grooves, thereby reducing the possibility of breakage of the vertical part of the L-shaped fastener.

Detailed Implementation

[0029] The following is a detailed description of a conveniently foldable and storable packaging box provided by this utility model, in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0030] like Figures 1-5 As shown, this embodiment of the present invention provides a conveniently foldable and storable packaging box, including a frame 1 and a support base 2. Folding side plates 3 are rotatably connected to the bottom of the two long sides of the frame 1. The folding side plates 3 are rotatably connected to the frame 1 via a pivot, and to the support base 2 via a pivot. Limiting side plates 4 are rotatably connected to the bottom of the two short sides of the frame 1. The limiting side plates 4 are rotatably connected to the frame 1 via a pivot, and to the top of the inner wall of the support base 2. The limiting side plates 4 abut against the top of the inner wall of the support base 2. A top cover (not shown) is placed on top of the frame 1 for assembly into a packaging box. In use, the folding side plates 3 are unfolded, and the two limiting side plates 4 are rotated downwards between the two folding side plates 3 to form a limit, preventing the two folding side plates 3 from bending inwards. For storage, the limiting side plates 4 are rotated upwards, and then the folding side plates 3 are folded inwards. The frame 1 is moved downwards to fit against the surface of the support base 2, and the limiting side plates 4 are fitted against the top of the folding side plates 3. The packaging box also includes:

[0031] The fixing mechanism 5 includes two L-shaped fixing parts 8 rotatably connected to the outside of the short side of the frame 1. The two L-shaped fixing parts 8 are symmetrically arranged about the middle of the frame 1. The top of the horizontal part of the L-shaped fixing part 8 is integrally formed with a snap-fit ​​part 9. The surface of the limiting side plate 4 is provided with a fixing hole 15. The L-shaped fixing part 8 is made of thermoplastic elastomer material.

[0032] In use, the horizontal snap-fit ​​part 9 of the L-shaped fastener 8 passes through the fixing hole 15 and snaps onto the inner side of the limiting side plate 4. The frame 1 forms the top frame of the packaging box, and the support base 2 provides bottom support. After the folding side plate 3 and the limiting side plate 4 are unfolded, they form the side wall of the packaging box, enabling the storage of items. The L-shaped fastener 8 is rotatably connected to the outside of the short side of the frame 1. The symmetrical arrangement ensures balanced force. In use, the snap-fit ​​part 9 passes through the fixing hole 15 and snaps onto the inner side of the limiting side plate 4, forming a mechanical limit, restricting the rotation of the limiting side plate 4, and preventing the limiting side plate 4 from shifting when impacted. This ensures the supporting and limiting effect of the limiting side plate 4 on the folding side plate 3, ensuring the structural stability of the packaging box after unfolding, and allowing for normal storage of items.

[0033] like Figure 3As shown in this embodiment, a mounting base 6 is fixed to the outer side of the short side of the frame 1, and a round rod 7 is fixed to the inner wall of the mounting base 6. An L-shaped fastener 8 is movably sleeved on the surface of the round rod 7. Two limiting rings are fixedly sleeved on the surface of the round rod 7, and the two limiting rings are attached to both sides of the L-shaped fastener 8. The mounting base 6 is fixed to the outer side of the short side of the frame 1 to provide a mounting carrier for the round rod 7 and ensure the stability of the position of the round rod 7. The L-shaped fastener 8 is movably sleeved on the surface of the round rod 7, and the round rod 7 provides a rotation fulcrum for the L-shaped fastener 8, so that the L-shaped fastener 8 can rotate flexibly around the round rod 7, which facilitates the engagement of the snap-fit ​​part 9 with the fixing hole 15 and the fixing hole 20. The two limiting rings are attached to both sides of the L-shaped fastener 8 to restrict the L-shaped fastener 8 from moving axially along the round rod 7, so as to prevent the L-shaped fastener 8 from shifting and causing the snap-fit ​​part 9 to fail to align with the fixing hole, thus ensuring the normal use of the L-shaped fastener 8. At the same time, the mounting base 6 can also be used as a handling handle to facilitate personnel to hold and carry the packaging box.

[0034] like Figures 3-5 As shown in this embodiment, the bottom of the L-shaped fastener 8 is fixed with an inclined plate 11. The bottom of the inclined plate 11 is inclined outward. When it is necessary to remove the snap-fit ​​part 9, the fingers can hold the inclined plate 11 and apply force outward to drive the L-shaped fastener 8 to rotate around the round rod 7, so that the horizontal end of the L-shaped fastener 8 moves downward, thereby allowing the snap-fit ​​part 9 to disengage from the limiting side plate 4 or the inner side of the support seat 2. The setting of the inclined plate 11 increases the distance between the force application point and the rotation fulcrum, reduces the operating force, and makes it easier and more convenient to remove the snap-fit ​​part 9.

[0035] like Figure 3 and Figure 4 As shown in this embodiment, a protrusion 12 is integrally formed on the bottom of the inclined plate 11 near the limiting side plate 4. The protrusion 12 is arc-shaped and integrally formed on the bottom of the inclined plate 11. The arc-shaped structure increases the contact area between the finger and the inclined plate 11, improves the friction between the finger and the inclined plate 11, and prevents the finger from slipping when the inclined plate 11 is pressed. This ensures that the force is stably transmitted to the L-shaped fixing member 8, so that the locking part 9 can smoothly disengage from the limiting position, further improving the stability and convenience of operation.

[0036] like Figure 5 As shown in this embodiment, a curved groove 13 is provided on the surface of the vertical part of the L-shaped fastener 8. The curved groove 13 is provided on the surface of the vertical part of the L-shaped fastener 8, which reduces the local thickness of the vertical part. When the L-shaped fastener 8 is rotated to remove the snap-fit ​​part 9, the vertical part of the L-shaped fastener 8 needs to be slightly bent. The curved groove 13 can reduce the bending resistance of the vertical part, making the bending process easier and avoiding difficulty in rotation due to excessive rigidity of the vertical part, thus ensuring the flexible operation of the L-shaped fastener 8.

[0037] like Figure 5As shown, in this embodiment, the top and bottom of the inner wall of the curved groove 13 are provided with arc-shaped surfaces 14, which eliminates the sharp structure of the corners of the curved groove 13. When the vertical part of the L-shaped fastener 8 is bent, the arc-shaped surfaces 14 can disperse the stress, avoid stress concentration at the corners of the curved groove 13, reduce the probability of the vertical part of the L-shaped fastener 8 breaking due to bending, and extend the service life of the L-shaped fastener 8.

[0038] like Figure 2 As shown in this embodiment, a fixing hole 10 is provided on the outer side of the short side of the support base 2. After the folding side plate 3 is folded, the snap-fit ​​part 9 of the horizontal part of the L-shaped fastener 8 passes through the fixing hole 10 and snaps onto the inner side of the support base 2 to form a fixed structure. This structure restricts the relative movement between the frame 1 and the support base 2, and prevents the frame 1 from separating from the support base 2 during the transportation of the folded packaging box, ensuring the stability of the folded state and facilitating storage and transportation.

[0039] like Figure 5 As shown in this embodiment, the vertical part of the L-shaped fixing member 8 is integrally formed with anti-slip stripes. The anti-slip stripes can increase the friction between the fingers and prevent the fingers from separating from the L-shaped fixing member 8, thereby improving the stability of operation.

[0040] Working principle: When the packaging box is unfolded, the L-shaped fixing part 8 is rotated so that the horizontal part of the locking part 9 passes through the fixing hole 15 on the surface of the limiting side plate 4 and is locked in the inner side of the limiting side plate 4. The position of the limiting side plate 4 is limited by the locking part 9.

[0041] When folding and storing, hold the inclined plate 11 at the bottom of the L-shaped fastener 8 with your fingers, and use the protrusion 12 to increase the friction. Pull outward to make the snap-fit ​​part 9 disengage from the inside of the limiting side plate 4. Turn the L-shaped fastener 8 out of the fixing hole 15. Rotate the folding side plate 3 and the limiting side plate 4 to make the frame 1 fit with the support base 2. Then rotate the L-shaped fastener 8 to let the snap-fit ​​part 9 pass through the fixing hole 10 on the outside of the short side of the support base 2 and snap into the inside of the support base 2 to complete the folding and fixing.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
