Technical Field

[0001] This utility model belongs to the field of cardboard box technology, specifically relating to a green cardboard box made of recycled materials. Background Technology

[0002] Recycled green cardboard boxes are environmentally friendly cardboard boxes made from recycled paper or waste paper. They not only help reduce deforestation and resource consumption, but also effectively reduce waste emissions, supporting sustainable development and the circular economy.

[0003] Problems with existing technology:

[0004] The bottom sealing of existing cardboard boxes typically uses adhesive tape to connect the two cardboard panels. While convenient, this method suffers from drawbacks, including the adhesive melting in summer, reduced adhesion, and easy breakage, preventing repeated use. Therefore, finding a way to connect the cardboard panels through their own structure is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide a green cardboard box made of recycled materials. The design of the handle and lifting pin allows the bottom of the cardboard box to be sealed without the use of tape. It also has a stronger load-bearing capacity and is more environmentally friendly. At the same time, the design of the trapezoidal rotation limit block and wedge hole not only makes the connection between the bottom plate and the handle more stable, but also has the function of preventing accidental operation.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A green cardboard box made of recycled material includes: a side panel of the cardboard box, with handles provided inside on both sides of the side panel, and a bottom plate rotatably connected to both ends of the bottom of the side panel;

[0008] Both ends of the two base plates that are close to each other are rotatably connected to extension connecting plates, and the two extension connecting plates are attached to the side panels of the carton.

[0009] A rigid connecting rod is fixedly connected to the bottom of the handle. A lifting pin is fixedly connected to the rigid connecting rod at the position corresponding to the position of the extension connecting plate. The end of the lifting pin extends to the outside of the carton side panel and is rotatably connected to a trapezoidal rotation limit block. A wedge-shaped hole is opened at the position corresponding to the position of the trapezoidal rotation limit block on the extension connecting plate.

[0010] The wedge-shaped hole is wedge-shaped and sleeved on the outside of the lifting pin, the trapezoidal rotation limiting block is trapezoidal, and the bottom shape of the wedge-shaped hole is similar to that of the trapezoidal rotation limiting block.

[0011] The side panel of the carton has a vertical groove corresponding to the handle position, and the handle is slidably disposed in the groove. The side panel of the carton has a reserved groove corresponding to the rigid connecting rod position, and the rigid connecting rod is slidably disposed in the reserved groove.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This invention, through the design of handles and lifting pins, allows the bottom of the carton to be sealed without the use of tape, and also has a stronger load-bearing capacity and is more environmentally friendly.

[0014] This utility model, through the design of trapezoidal rotation limit block and wedge hole, not only makes the connection between the base plate and the handle more stable, but also has an emergency function for accidental operation. Attached Figure Description

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figure 1 As shown, a green cardboard box made of recycled material includes: a cardboard box side panel 1, with handles 3 provided inside both sides of the cardboard box side panel 1, and a bottom plate 2 rotatably connected to both ends of the bottom of the cardboard box side panel 1.

[0023] When in use, the handle 3 is lifted by hand. The design of the handle 3 can limit the end of the bottom plate 2, so that the two bottom plates 2 can seal the bottom of the carton side plate 1.

[0024] See attached document Figure 2 The wedge-shaped hole 203 is wedge-shaped and sleeved on the outside of the lifting pin 204. The trapezoidal rotation limit block 202 is trapezoidal. The bottom shape of the wedge-shaped hole 203 is similar to that of the trapezoidal rotation limit block 202. Both sides of the two bottom plates 2 that are close to each other are rotatably connected to the extension connecting plate 201. The two extension connecting plates 201 are attached to the carton side plate 1.

[0025] According to the above structure, during installation, the base plate 2 is first folded under the side plate 1 of the carton, and the bottom of the side plate 1 of the carton is sealed by the two base plates 2. Since the trapezoidal rotation limit block 202 is similar in shape to the wedge hole 203, the wedge hole 203 is passed through the trapezoidal rotation limit block 202 to make the extension connecting plate 201 fit with the side plate 1 of the carton. Then, the trapezoidal rotation limit block 202 is rotated 180° so that the trapezoidal rotation limit block 202 and the wedge hole 203 can no longer pass through, which can achieve the effect of separating the two by passing through the wedge hole 203 through the trapezoidal rotation limit block 202. The trapezoidal rotation limit block 202, the extension connecting plate 201, and the lifting pin 204 are all made of environmentally friendly materials with high hardness and not easily deformed.

[0026] See attached document Figures 3-4 A rigid connecting rod 301 is fixedly connected to the bottom of the handle 3. A lifting pin 204 is fixedly connected to the rigid connecting rod 301 at the position corresponding to the extension connecting plate 201. The end of the lifting pin 204 extends to the outside of the carton side plate 1 and is rotatably connected to a trapezoidal rotation limit block 202. A wedge-shaped hole 203 is opened at the position corresponding to the trapezoidal rotation limit block 202 on the extension connecting plate 201. A sliding groove is vertically opened at the position corresponding to the handle 3 on the carton side plate 1. The handle 3 is slidably set with the sliding groove. A reserved groove 101 is opened at the position corresponding to the rigid connecting rod 301 on the carton side plate 1. The rigid connecting rod 301 is slidably set with the reserved groove 101.

[0027] According to the above structure, when a large number of items are placed inside the side panel 1 of the carton, the internal weight increases. When the side panel 1 needs to be lifted, first grasp the handle 3 and lift it upwards. Then, the handle 3 slides upwards inside the slide groove, and the top of the handle 3 contacts the side panel 1 of the carton. The upward pushing force of the handle 3 overcomes the weight of the carton and the objects inside it and lifts the carton. If the carton is lifted upwards without grasping the handle 3, the bottom plate 2 will rotate under the action of the weight inside the carton. However, because the wedge hole 203 is fitted outside the lifting pin 204, and the vertical height of the wedge hole 203 is smaller than the horizontal length of the bottom plate 2 (length ratio of 20:1), the wedge hole 203 restricts the lifting pin 204. The bottom plate 2 will only rotate slightly, that is, a small gap appears in the middle of the two bottom plates 2, and the items are not easy to pass through and fall. This design is an emergency design for accidental operation.

[0028] In this system, the weight of the carton is transmitted to the handle 3 through the base plate 2. The connection between the base plate 2 and the side plate 1 of the carton, and the connection between the base plate 2 and the extension connecting plate 201, provides the base plate 2 with the force to support the contents of the carton. When the handle 3 moves upward, it pulls the rigid connecting rod 301 upward. The rigid connecting rod 301 pulls the lifting pin 204 and the lifting pin 204 fixedly connected to it upward, so that the lifting pin 204 engages with the top of the wedge-shaped hole 203 and provides an upward force to overcome the weight of the contents of the carton. In this way, the bottom of the side plate 1 of the carton can be sealed without the need for tape.

[0029] The working principle of this utility model is as follows: During installation, the bottom plate 2 is first folded to the bottom of the carton side plate 1, and the bottom of the carton side plate 1 is sealed by the two bottom plates 2. The trapezoidal rotation limiting block 202 is similar in shape to the wedge hole 203. The wedge hole 203 is passed through the trapezoidal rotation limiting block 202 so that the extension connecting plate 201 is attached to the carton side plate 1. Then the trapezoidal rotation limiting block 202 is rotated 180° so that the trapezoidal rotation limiting block 202 and the wedge hole 203 can no longer pass through, which can achieve the effect of separating the two by passing through the trapezoidal rotation limiting block 202.

[0030] When lifting the side panel 1 of the carton, first grasp the handle 3 and lift it upwards. Then, the handle 3 slides upwards inside the groove. The top of the handle 3 contacts the side panel 1 of the carton. The upward pushing force of the handle 3 overcomes the weight of the carton and its internal objects and lifts the carton.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
