Description

Technical Field

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

[0002] Gifts are an indispensable part of people's lives throughout history and across the world. Gift boxes are practical gift packaging designed to express affection between relatives and friends, reflecting consumers' spiritual needs. Gift packaging boxes are also a concrete manifestation of gift culture. Cylindrical protective packaging boxes are often used to store and package rolled-up books, paintings, and other items to protect them from external damage as much as possible.

[0003] Referring to existing patent publication number CN220483962U, a cylindrical packaging box includes a box body with an open upper end. The box body has a storage cavity with a square cross-section inside. Multiple elastic walls are fixed to each side wall of the storage cavity, and these elastic walls are located at the vertical centerline of the inner side wall of the storage cavity. Each elastic wall includes a fixing part and an elastic part. One side of the fixing part is fixed to the side wall of the storage cavity. The cylindrical packaging box provided in this application can position the scroll within the storage cavity, preventing the scroll from shaking or impacting the inner wall of the storage cavity, thus protecting the scroll during transportation and movement.

[0004] However, in actual use, existing packaging boxes often have limitations. The connection between the lid and the box is loose, often using a snap-fit ​​method, which results in poor stability. Some boxes are secured with ropes or tape, making the process cumbersome and the sealing effect inadequate. Furthermore, smaller items are prone to shifting inside the box, causing them to bump against it and further compromising the protective effect. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a cylindrical packaging box. This invention allows for the placement of items inside the box, with a pressing component activating the locking mechanism. When the lid is connected to the box body, the pressing component returns to its initial position, enabling the locking mechanism to engage with the box body and secure the lid and body. This facilitates sealing the packaging box, is convenient to operate, and is relatively stable.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cylindrical packaging box, comprising:

[0008] The box is cylindrical in shape and has an opening at one end;

[0009] A lid, which is fitted onto the open end of the box body to close the box body;

[0010] A connecting rod is horizontally connected inside the box cover, and a locking part is sleeved on the surface of the connecting rod. The locking part is configured to rotate about the axis of the connecting rod, and the locking parts are arranged in a cross pattern.

[0011] The surface of the lid is equipped with a pressing component, and the internal structure of the box body has a protective component.

[0012] The present invention is further configured such that the pressing assembly includes: a mounting part, a pressing part, a second elastic element, and a pressure plate;

[0013] The mounting part is fixedly mounted on the surface of the box cover, the second elastic element is mounted on the inner side of the mounting part, the pressure plate is mounted on one movable end of the second elastic element, and the pressing part is mounted on the end of the pressure plate that contacts the mounting part.

[0014] The present invention is further configured such that the pressing part is located inside the second elastic member, and the pressing part extends through to the outside of the mounting part.

[0015] The present invention is further configured such that the pressure plate is located directly above the locking part vertically, and the pressure plate is in contact with the locking part.

[0016] The present invention further provides that the protective component includes: a first elastic element, a movable element, a connecting element, a protective pad, and a guide portion;

[0017] The first elastic element is vertically installed inside the lower part of the box body, the movable element is installed at the end of the first elastic element away from the box body, the protective pad is installed on the inner side of the box body through the guide part, and the connecting parts are all connected between the protective pad and the movable element.

[0018] The present invention is further configured such that one end of the connector is inclined downward along the direction of the movable part.

[0019] The present invention is further configured such that the protective pad is arc-shaped, and the protective pad is configured to move closer to each other in the horizontal direction when the movable part is subjected to vertical downward pressure.

[0020] The present invention is further configured such that the locking part is elastic, and the end of the locking part away from the connecting rod can be connected to the box body.

[0021] The beneficial effects of this utility model are as follows: After the item is placed inside the packaging box, the pressing component can drive the locking part to move. Then, when the box lid is connected to the box body, the pressing component returns to the initial position, so that the locking part can hook with the box body to limit the distance between the box lid and the box body, making it easy to close the packaging box. It is convenient to operate and relatively stable.

[0022] 1. This cylindrical packaging box, with its locking part and pressing component working together, allows personnel to press the pressing part when packaging and protecting items. This pushes the pressure plate downward and stretches the second elastic element, causing the pressure plate to retract. After the lid and body are closed, releasing the pressing part allows the second elastic element to pull the pressure plate back to its original position. The locking part then opens to hook onto the body, thus securing the lid and body and facilitating the sealing of the packaging box. The operation is convenient and relatively stable.

[0023] 2. This cylindrical packaging box, by being equipped with protective components, allows the pressure generated by the weight of the item itself to move the movable part downwards and compress the first elastic element when the item is placed inside the box. During this vertical downward movement, the movable part can pull the protective pad horizontally through the connecting part. Then, the two protective pads will come closer together to clamp and limit the item, thereby reducing the space for the item to move and preventing the item from being shaken and bumped when it is inside the packaging box, thus improving the protective effect.

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0033] Reference Figure 1-4 A cylindrical packaging box includes: a box body 1, which is cylindrical and has an opening at one end; a lid 2, which is fitted onto the opening end of the box body 1 to close the box body 1; a connecting rod 11, which is horizontally connected to the inside of the lid 2, and a locking part 12 is fitted onto the surface of the connecting rod 11. The locking part 12 is configured to rotate around the axis of the connecting rod 11, and the locking parts 12 are arranged in a cross pattern; a pressing component is installed on the surface of the lid 2, which can drive the locking part 12 to move, so that the locking part 12 can lock the connection between the lid 2 and the box body 1 after it moves, thereby improving the stability and connection strength of the packaging box and making it easy to operate. The box body 1 has a protective component inside, which can protect the items placed in the packaging box to a certain extent and reduce the movement space of the packaged items.

[0034] Specifically, refer to Figure 1-4The pressing assembly includes: a mounting part 3, a pressing part 4, a second elastic member 13, and a pressure plate 6. The mounting part 3 is fixedly mounted on the surface of the lid 2. The second elastic member 13 is mounted inside the mounting part 3. The pressure plate 6 is mounted on one movable end of the second elastic member 13. The pressing part 4 is mounted on the end of the pressure plate 6 that contacts the mounting part 3. In this embodiment, by pressing the pressing part 4, the pressing part 4 can push the pressure plate 6 downward and stretch the second elastic member 13. At this time, the pressure plate 6 can drive the locking part 12 to close. Furthermore, the locking part 12 is elastic, and the end of the locking part 12 away from the connecting rod 11 can be connected to the box body 1. So that after the lid 2 and the box body 1 are closed, the pressing part 4 is released, and the second elastic member 13 can pull the pressure plate 6 to reset. At this time, the locking part 12 can open to hook with the box body 1, thereby limiting the distance between the lid 2 and the box body 1.

[0035] Furthermore, the pressing part 4 is located inside the second elastic member 13, and part of the pressing part 4 extends through the mounting part 3. This design allows the movement of the pressure plate 6 to be more stable. The pressing part 4 guides and limits the second elastic member 13, preventing the pressure plate 6 from wobbling under the action of the second elastic member 13. At the same time, the pressing part 4 is located outside the mounting part 3, making it convenient for personnel to operate the pressing assembly through the pressing part 4.

[0036] Furthermore, the pressure plate 6 is located directly above the locking part 12, and the pressure plate 6 is in contact with the locking part 12. This design allows the pressure plate 6 to move the locking part 12 more smoothly when it moves vertically, and the contact between the pressure plate 6 and the locking part 12 can press the locking part 12 well, so that the locking part 12 closes under its own elasticity.

[0037] Specifically, refer to Figure 2-3 The protective components include: a first elastic element 10, a movable element 9, a connecting element 8, a protective pad 7, and a guide part 5. The first elastic element 10 is vertically installed inside the lower part of the box body 1. The movable element 9 is installed at the end of the first elastic element 10 away from the box body 1. The protective pad 7 is installed on the inner side of the box body 1 through the guide part 5. The connecting element 8 is connected between the protective pad 7 and the movable element 9. In this embodiment, when the item is placed in the packaging box, the pressure generated by the weight of the item itself can drive the movable element 9 to move downward and compress the first elastic element 10. At this time, during the vertical downward movement, the movable element 9 can pull the protective pad 7 to move horizontally through the connecting element 8. Then, the two protective pads 7 will move closer to each other to clamp and limit the item, thereby reducing the activity space of the item and preventing the item from being shaken and bumped when it is in the packaging box, thus improving the protective effect.

[0038] Furthermore, one end of the connector 8 is inclined downward along the direction of the movable part 9. This design allows the movable part 9 to move horizontally under the guidance of the connector 8 during its vertical downward movement, thus enabling the connector 8 to better transmit the force and improve stability.

[0039] Furthermore, the protective pad 7 is arc-shaped and is configured to move closer to each other in the horizontal direction when the movable part 9 is subjected to vertical downward pressure. This design allows the protective pad 7 to fit well against the cylindrical item, thereby clamping and protecting the item under the action of the protective pad 7 and reducing the impact of shaking on the item.

[0040] Working principle: When using this utility model, first place the item inside the packaging box. Then, when closing the box lid 2 onto the box body 1, press the pressing part 4 so that it pushes the pressure plate 6 downward and stretches the second elastic member 13. At this time, the pressure plate 6 can drive the locking part 12 to close. After the box lid 2 and box body 1 are closed, release the pressing part 4. The second elastic member 13 can pull the pressure plate 6 back to its original position. At this time, the locking part 12 can open to hook onto the box body 1, thereby limiting the distance between the box lid 2 and the box body 1. It is convenient and stable to seal the packaging box. When the item is placed inside the packaging box, the pressure generated by the weight of the item itself can drive the movable part 9 to move downward and compress the first elastic part 10. At this time, the movable part 9 can pull the protective pad 7 to move horizontally through the connecting part 8 during the vertical downward movement. Then the two protective pads 7 will come closer to each other to clamp and limit the item, thereby reducing the space for the item to move and preventing the item from being shaken and bumped when it is inside the packaging box, thus improving the protective effect.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
