Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a packaging structure with good fire resistance. Background Technology

[0002] Packaging boxes are very common in daily life, including tea packaging boxes. Some tea packaging boxes use cylindrical lifting boxes, making the tea appear more unique and upscale.

[0003] A search revealed a lifting tea packaging box with application number 202420451400.3. This device uses a support cylinder with a dehumidification hole at the bottom of the inner box. This not only dehumidifies the inner box, but also allows air to enter the support cylinder through the dehumidification hole and pass through the hole to the bottom of the support cylinder, preventing negative pressure between the bottom plate and the outer box. This allows consumers to easily pull out the inner box from the outer box. However, each time the inner box is used, all inner boxes must be pulled out together, exposing the tea leaves inside the other inner boxes to the air, which can easily cause moisture damage and affect the quality. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a packaging structure with good fire resistance to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a packaging structure with good fire resistance, including an outer packaging box, a rotating cylinder connected to the lower part of the outer packaging box, a first spring and a rotating shaft connected inside the rotating cylinder, a support plate connected to the outer surface of the rotating shaft through a connecting block, an inner packaging box placed on top of the support plate, a notch opened at the top of the outer packaging box, a movable cover connected to one side of the top of the outer packaging box through a hinge, and the position of the movable cover corresponding to the notch, a lever movably connected to the top of the outer packaging box, a pin connected to the bottom of the lever, and a second spring connected to one side of the pin.

[0006] Furthermore, there are four inner packaging boxes in total, and the four inner packaging boxes are distributed in a circular array.

[0007] By adopting the above technical solution, when using the product, the tea leaves are placed in four inner packaging boxes. When you want to taste the tea leaves in a certain inner packaging box, you rotate the packaging box to the opening, open the movable cover, and under the action of the first spring, the support plate moves the inner packaging box upward a certain distance, pushing the inner packaging box out of the opening, thus making it easy to take out.

[0008] Furthermore, the upper part of the inside of the outer packaging box and the bottom of the movable lid are coated with Teflon.

When the packaging box is burned by a fire source, the Teflon coating can also hinder the conduction of heat to the inner packaging box, thereby avoiding loss.

[0010] Further, the rotating shaft is internally provided with four guide grooves, and the support plate is slidably connected with the guide grooves through the connecting blocks.

[0011] By adopting the above technical scheme, when it is needed to take tea in a certain inner packaging box, the rotating drum is rotated to rotate the inner packaging box to the position corresponding to the gap, the movable cover is opened, the connecting blocks and the guide grooves are matched to limit and guide the support plate, and under the action of the first spring elastic force, the support plate drives the inner packaging box to move upward to a certain distance from the gap, thereby facilitating personnel to take.

[0012] Further, the rotating drum is externally connected with a label plate, and the label plate corresponds to the positions of the inner packaging boxes.

[0013] By adopting the above technical scheme, the tea in the inner packaging box is marked on the label plate and pasted on the label plate. When it is needed to take tea in a certain inner packaging box, the corresponding label plate is rotated to the position corresponding to the gap by observing the information on the label plate, so that it is not necessary to open and observe the inner packaging boxes one by one, thereby facilitating personnel to selectively take.

[0014] Further, the latch is in the shape of "L", and one side of the latch is arc-shaped.

[0015] By adopting the above technical scheme, the movable cover is internally provided with a limiting hole corresponding to the latch. When the movable cover is closed, the bottom of the movable cover extrudes the latch to move and compress the second spring. When the latch corresponds to the limiting hole, the latch enters the limiting hole under the action of the second spring elastic force, thereby locking the movable cover to seal and protect the inner packaging box. When taking, the user drives the latch to move by the tab to extrude the second spring and release the restriction on the movable cover, thereby opening the movable cover.

[0016] Further, the rotating drum is rotatably connected with the outer packaging box.

[0017] By adopting the above technical scheme, the rotating drum and the outer packaging box are integrally formed. The user rotates the rotating drum to drive the rotating shaft to rotate, and the connecting blocks and the guide grooves are matched to drive the support plate to rotate, thereby driving the inner packaging box to rotate, thereby facilitating the user to selectively take and use.

[0018] Further, the outer packaging box is made of ceramic, and the inner wall of the outer packaging box is double-layered.

[0019] By adopting the above technical scheme, when the outer packaging box is burned by a fire source, since the ceramic material has good thermal stability, and the inner wall is double-layered and the inner wall interlayer is vacuum-treated, the temperature when heat extends to the inside of the outer packaging box can be reduced, thereby improving the fire resistance of the device.

[0020] Further, the rotating drum and the outer surface of the outer packaging box are both provided with raised lines.

[0021] By adopting the above technical scheme, the sizes of adjacent two raised lines are different, the rotating drum is convenient for a user to observe the rotating angle by the raised lines, so as to judge whether the inner packaging box to be taken out is rotated to the notch position, and the raised lines increase the friction resistance between the rotating drum and the outer packaging box, so that the user is more labor-saving when rotating the rotating drum.

[0022] Further, the rotating drum is connected with a soft pad made of rubber.

[0023] By adopting the above technical scheme, when the outer packaging box is placed on a desktop, the soft pad enhances the friction between the bottom of the rotating drum and the desktop, so as to avoid that the outer packaging box is not placed stably and falls over.

[0024] In summary, the utility model mainly has the following beneficial effects:
