Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a paper packaging box with a reinforced frame. Background Technology

[0002] Paper packaging boxes are a type of packaging material widely used in logistics, warehousing, and commodity transportation. They have advantages such as low cost, light weight, and ease of processing and printing.

[0003] To increase the structural strength of existing paper packaging boxes and thus protect the contents inside, some paper packaging boxes have reinforced frames added to their interior or exterior. These reinforced frames are generally made of metal or non-metal materials, such as plastic, wood or composite materials, and are assembled by means of tenon, nailing or plugging. Such paper packaging boxes with additional reinforced frames can be called paper packaging boxes with reinforced frames.

[0004] However, existing reinforced frame paper boxes are generally square. When transporting large quantities of these reinforced frame paper boxes by truck, they may not completely fill the truck's interior space, resulting in gaps between the reinforced frame paper boxes and the truck bed. Subsequently, during vehicle travel, these reinforced frame paper boxes may shake or shift, causing collisions between themselves and the truck bed, potentially damaging the goods inside. Therefore, they do not meet the current requirements. To address this, we propose a paper box with a reinforced frame. Utility Model Content

[0005] The purpose of this invention is to provide a paper packaging box with a reinforced frame to solve the problems mentioned in the background art. Existing paper packaging boxes with reinforced frames are generally square. When transporting large quantities of these boxes by truck, they may not completely fill the truck's interior space, resulting in gaps between the boxes and the truck bed. Subsequently, during vehicle travel, the boxes may shake or shift, causing impacts and potentially damaging the goods inside.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a paper packaging box with a reinforced frame, comprising a paper packaging box, wherein a reusable reinforced frame is provided on the outer side of the paper packaging box, and a gap filling plate is provided on the front and rear end faces of the reusable reinforced frame, wherein a plug rod is fixed at each of the four end corners of the rear end face of the gap filling plate and is movably inserted into the outer shell of the paper packaging box, wherein a rubber strip is fixed on one side of the outer surface of the plug rod located inside the paper packaging box, and a manual rotating shaft is provided on one side of the two opposite rubber strips, wherein a threaded rod is connected to the face of the manual rotating shaft facing the paper packaging box, and a connecting plate is installed on one side of the outer surface of the threaded rod through a threaded structure, and a metal rod is provided on both sides of the threaded rod that movably penetrates the connecting plate;

[0015] 1. This utility model features a gap-filling plate on the outer surface of both the front and rear ends of a paper packaging box, with a movable insert rod inside a reusable reinforcing frame fixed to its outer surface. When the reusable reinforcing frame containing the paper packaging box is placed inside a truck, and there is a gap between the reusable reinforcing frame and the inner wall of the truck bed, the gap-filling plate corresponding to the gap is pulled outward until it is in contact with the inner wall of the truck bed. Once in contact, the reusable reinforcing frame is supported, thus preventing it from shaking or colliding with the inner wall of the truck bed due to external forces generated during truck travel. This technical solution improves the overall environmental adaptability of the equipment and prevents collisions between the equipment and the truck bed.

[0016] 2. This utility model allows for the fixation of the insert rod that is fixed to the gap filling plate by manually rotating the manual shaft after the gap filling plate is pulled outward to fit against the inner wall of the truck bed. Once the insert rod is fixed, the gap filling plate directly fixed to it will also be fixed. By fixing the gap filling plate, it is possible to prevent the gap filling plate from being pushed by the impact force generated during vehicle movement, thereby preventing the gap between the equipment and the truck bed from being created again. The above technical solution improves the overall stability of the equipment. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] The paper packaging box 1 (model BC), toothed bar 9 (model 4M), and threaded rod 12 (model M10) mentioned in this utility model can be obtained from the market or through private customization.

[0025] Please see Figures 1 to 5 An embodiment of this utility model is provided: a paper packaging box with a reinforced frame, including a paper packaging box 1, a reusable reinforced frame 2 on the outside of the paper packaging box 1, a gap filling plate 3 on the front and rear ends of the reusable reinforced frame 2, a plug rod 4 that can be inserted into the outer shell of the paper packaging box 1 is fixed at the four corners of the rear end of the gap filling plate 3, a rubber strip 5 is fixed on one side of the outer surface of the plug rod 4 located inside the paper packaging box 1, a manual rotating shaft 13 is provided on one side of the two opposite rubber strips 5, a threaded rod 12 is connected to the face of the manual rotating shaft 13 facing the paper packaging box 1, a connecting plate 11 is installed on one side of the outer surface of the threaded rod 12 through a threaded structure, and a metal rod 16 that can be inserted through the connecting plate 11 is provided on both sides of the threaded rod 12.

[0026] Both ends of the connecting plate 11 are fixedly connected to a toothed row 9, and the toothed end face of the toothed row 9 faces the rubber strip 5.

[0027] The upper end of the reusable reinforcing frame 2 is covered with a sealing cover. The four corners of the upper end of the reusable reinforcing frame 2 are fixed to the sealing cover by snaps. Both the reusable reinforcing frame 2 and the sealing cover are made of aluminum alloy in one piece. When the equipment needs to be used, the paper packaging box 1 is placed inside the reusable reinforcing frame 2, and then the sealing cover is fixed to the upper end of the reusable reinforcing frame 2 by snaps.

[0028] The manual rotating shaft 13 has a circular groove 15 on the outer surface of the reusable reinforcing frame 2. The circular groove 15 has a rotating head 14 fixed to the outer surface of the manual rotating shaft 13. When the reusable reinforcing frame 2 containing the paper packaging box 1 is placed inside the truck, and there is a gap between the reusable reinforcing frame 2 and the inner wall of the truck body, the gap filling plate 3 corresponding to the gap is pulled outward until the gap filling plate 3 is in contact with the inner wall of the truck body. When the two are in contact, the reusable reinforcing frame 2 can be supported, thereby preventing the reusable reinforcing frame 2 from shaking or even colliding with the inner wall of the truck body due to the external force generated during the truck's operation. Through the above technical solution, the overall environmental adaptability of the equipment is improved, thereby preventing the equipment from colliding with the truck body.

[0029] When the gap filling plate 3 is pulled outward to fit against the inner wall of the truck bed, the manual rotating shaft 13 is manually rotated via the rotating head 14. During the rotation of the manual rotating shaft 13, the threaded rod 12 fixed to it will rotate along with it. When the threaded rod 12 rotates, the connecting plate 11, which is threaded to it but cannot rotate on its own due to being pierced by two metal rods 16, will move inward or outward under the drive of the threaded structure. At this time, when the connecting plate 11 moves inward, the toothed rack 9 fixed to it will also move inward along with it. As the toothed rack 9 moves, the teeth fixed on the toothed rack 9 will bite into the interior of the rubber strip 5 fixed on the outer surface of the insert rod 4, thereby fixing the rubber strip 5 and the insert rod 4. After the insert rod 4 is fixed, the gap filling plate 3 directly fixed to it will also be fixed together. By fixing the gap filling plate 3, it is possible to prevent the gap filling plate 3 from being pushed by the impact force generated during vehicle travel, thereby preventing the gap between the equipment and the truck body from being created again. The above technical solution improves the overall stability of the equipment.

[0030] During the fixed operation, it is only necessary to fix the point that is most convenient to operate at;

[0031] After the internal reusable reinforcing frame 2 containing the paper packaging box 1 is moved to the designated location, the paper packaging box 1 is removed, and then the reusable reinforcing frame 2 is reused.

[0032] The top end of the toothed head on the toothed row 9 is arc-shaped, and the toothed row 9 is slidably connected to the paper packaging box 1; the arc-shaped toothed head can prevent the toothed head that bites into the rubber strip 5 from causing great damage to the rubber strip 5.

[0033] A strip groove 6 is provided on one side of the insertion rod 4 inside the outer shell of the paper packaging box 1. A metal rod 7 is fixed inside the strip groove 6. An anti-detachment sleeve 8 is movably sleeved on one side of the outer surface of the metal rod 7, and the anti-detachment sleeve 8 is fixed to the insertion rod 4 with the side facing the insertion rod 4. The anti-detachment sleeve 8, which is fixed to the insertion rod 4 and movably sleeved on the outer surface of the metal rod 7, can prevent the insertion rod 4 and the gap filling plate 3 fixed to the insertion rod 4 from falling off.

[0034] The front end face of the first gap filling plate 3 and the rear end face of the second gap filling plate 3 from left to right are both provided with rubber reinforcing plates, and the outer surface of the rubber reinforcing plates is provided with multiple anti-slip stripes; the rubber reinforcing plates fixed to the outer surface of the gap filling plate 3 can alleviate the impact force applied to the equipment by the vehicle during driving, thereby protecting the overall equipment.

[0035] The outer side of the rubber strip 5 is provided with a strip-shaped mounting groove on the outer surface of the insert rod 4, and the rubber strip 5 is fixed inside the strip-shaped mounting groove by screws. When the rubber strip 5 has been used for too long and its whole body becomes more brittle and cracks have appeared due to repeated engagement of the toothed row 9, the screws fixing the rubber strip 5 can be removed to replace it.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
