Description

Technical Field

[0001] This utility model relates to the field of protective box technology, specifically a three-dimensional packaging box. Background Technology

[0002] A security case is a container specifically designed to protect its contents from damage. It is typically used for storing and transporting valuables, important documents, electronic equipment, chemicals, or other items requiring special protection.

[0003] For example, CN208549104U discloses a protective box, which includes a box body, a box cover, and a top plate. The top plate has heat dissipation holes and heat exchange holes. The box body also has a heat dissipation assembly, which includes a heat exchange fan group and a power supply unit. The heat exchange fan group and the power supply unit are electrically connected. The heat exchange holes include a first heat exchange hole and a second heat exchange hole. The heat exchange fan group includes an exhaust fan and a ventilation fan, which are fixed at the first heat exchange hole and the second heat exchange hole, respectively. The box body has a first baffle and a second baffle, which are horizontally slidable on the inner wall of the box body. This provides a protective box with good protection performance and high portability, which not only helps to extend the service life of the instrument but also greatly improves the working efficiency of the instrument.

[0004] For example, Chinese patent CN220181380U is the first-generation protective box applied for by our company. Although the protective box has certain advantages in protection, it still has certain drawbacks: when using the protective box, when multiple protective boxes are stacked together for transportation, they are prone to shifting due to bumps during transportation, which can easily cause them to fall off. Especially during field transportation, stacked protective boxes are very likely to fall off during bumps, which can easily cause damage. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a three-dimensional packaging box.

[0006] The purpose of this utility model is achieved through the following technical solution: a three-dimensional packaging box, including a box body, a box lid, an extraction device, and a locking block. The box lid is located at the top of the box body, and the locking block is fixed to the top of the box lid. The extraction device is provided in two sets, which are respectively located at the left and right ends of the box body. The extraction device includes a support block, a fixing rod, a handle, and a fixing mechanism. The support block is provided in two sets, both of which are fixed to the right end of the box body. The fixing rod is fixed between the two sets of support blocks. The handle is located on the outside of the fixing rod and is rotatably connected to the fixing rod. The fixing mechanism is provided in two sets, both of which are located at the bottom right end of the box body.

[0007] Preferably, the fixing mechanism includes a fixing block, a limiting block, a round rod, a spring, an adjusting block, and an adjusting groove. The fixing block is fixed to the right end of the main body of the packaging box. The limiting block, the round rod, the spring, the adjusting block, and the adjusting groove form a set of limiting components, and there are two sets of limiting components. They are symmetrically arranged inside the fixing block with the fixing block as the center. The limiting block is located inside the fixing block and extends rearward to the inner side of the fixing block. The round rod passes through the left end of the limiting block and is located inside the fixing block. The spring is located on the outer side of the round rod, and the front end of the spring is fixed to the inner front end of the fixing block. The adjusting block is fixed to the right end of the limiting block and extends to the right through the adjusting groove located at the right end of the fixing block. The adjusting groove is opened at the right end of the inner wall of the fixing block.

[0008] Preferably, the bottom of the main body of the packaging box is provided with a groove, and the position of the groove corresponds to the position of the locking block. This setting improves the stability of the main body of the packaging box when stacked.

[0009] Preferably, the bottom of the handle is provided with a non-slip rubber sleeve, which makes it more stable to hold the handle.

[0010] Preferably, the handle is U-shaped, which facilitates gripping.

[0011] Preferably, the right end face of the limiting block is inclined, and it is inclined from front to right to left. This setting allows the limiting block to move towards the fixed block by squeezing the inclined surface of the limiting block when the handle moves.

[0012] Preferably, the outer side of the round rod is smoothly arranged and is slidably connected to the limiting block, which makes the movement of the limiting block smoother.

[0013] Preferably, the outer side of the adjustment block is provided with anti-slip texture, which makes the movement of the adjustment block more stable.

[0014] This utility model has the following advantages: The three-dimensional packaging box of this utility model is equipped with an extraction device. Through the cooperation of support blocks, fixing rods and handles, it is easy to move the main body of the packaging box. When transporting multiple packaging boxes stacked together, the handle is turned upwards. When the handle moves, it squeezes the limiting block, causing the handle to enter the fixing block. Through the cooperation of the fixing block, handle and limiting block, the packaging boxes can play a supporting and restricting role when stacked. This setting improves the stability of the packaging boxes during transportation and stacking. When encountering bumpy roads, adjacent packaging boxes are pulled by the fixing mechanism, so that the stacked protective boxes become a whole, making it less likely to fall off during bumps, thereby improving transportation reliability and enhancing the stability of the stacked protective boxes. Moreover, the packaging boxes can be used individually, stacked into a wall, or stacked into a square structure. Therefore, during transportation, the transportation method can be selected from these three methods according to actual needs. Attached Figure Description

[0027] like Figures 1 to 4As shown, a three-part packaging box is provided by this utility model: the three-part packaging box includes a main body 1, a lid 2, an extraction device 3, and a locking block 4. The lid 2 is located at the top of the main body 1, and the locking block 4 is fixed to the top of the lid 2. The extraction device 3 has two sets, which are respectively located at the left and right ends of the main body 1. The extraction device 3 includes a support block 31, a fixing rod 32, a handle 33, and a fixing mechanism 34. The support block 31 has two sets, both of which are fixed to the right end of the main body 1, and the fixing rod 32 is fixed to the left and right ends of the main body 1. Between the support blocks 31, the handle 33 is located on the outside of the fixing rod 32 and is rotatably connected to the fixing rod 32. There are two sets of fixing mechanisms 34, both located at the bottom right end of the packaging box body 1. The bottom end of the packaging box body 1 is provided with a groove, and the position of the groove corresponds to the position of the locking block 4. This setting improves the stability of the packaging box body when stacked. The bottom end of the handle 33 is provided with an anti-slip rubber sleeve, which makes it more stable to hold the handle 33. The handle 33 is U-shaped, which makes it easy to grip the handle 33.

[0028] Please see Figure 5 This utility model provides a three-dimensional packaging box technical solution: the three-dimensional packaging box has a fixing mechanism 34 including a fixing block 341, a limiting block 342, a round rod 343, a spring 344, an adjusting block 345, and an adjusting groove 346. The fixing block 341 has a U-shaped cavity 347 inside, and the spring 344 is located inside the U-shaped cavity. The fixing block 341 is fixed to the right end of the main body 1 of the packaging box. The limiting block 342, the round rod 343, the spring 344, the adjusting block 345, and the adjusting groove 346 form a set of limiting components, and there are two sets of limiting components. They are symmetrically arranged inside the fixing block 341 with the fixing block 341 as the center. The limiting block 342 is located inside the fixing block 341 and extends backward to the inner side of the fixing block 341. The round rod 343 passes through the left end of the limiting block 342 and is located inside the fixing block 341. The spring 344 is located on the outside of the round rod 343, and the front end of the spring 344 is fixed to the front end of the fixed block 341. The adjusting block 345 is fixed to the right end of the limiting block 342, and the adjusting groove 346 is located on the right end of the fixed block 341. The adjusting groove 346 is opened on the right end of the inner wall of the fixed block 341. The right end face of the limiting block 342 is inclined and tilted from front to right to left. This setting allows the limiting block 342 to move towards the fixed block 341 by squeezing the inclined surface of the limiting block 342 when the handle 33 moves. The outside of the round rod 343 is smooth and slidably connected to the limiting block 342. This setting makes the movement of the limiting block 342 smoother. The outside of the adjusting block 345 is provided with anti-slip texture. This setting makes the movement of the adjusting block 345 more stable.

[0029] The working principle is as follows:

[0030] First, when using the packaging box body 1, if it is necessary to move the packaging box body 1, hold the handles 33 on both the left and right ends of the packaging box body 1, rotate the handles 33 along the fixed rod 32, and pull the handles 33 upward to lift the packaging box body 1.

[0031] Second, when multiple packaging box bodies 1 are stacked, after two sets of adjacent packaging box bodies 1 are stacked, turn the handle 33 upward so that the handle 33 rotates around the fixed rod 32. When the handle 33 moves to the right end face of the limiting block 342, it presses the inclined surface of the limiting block 342, causing the limiting block 342 to move into the fixed block 341. When the limiting block 342 moves, it presses the spring 344.

[0032] Third, when the handle 33 moves to the inside of the fixed block 341, the spring 344 loses its force and releases elastic potential energy to push the limiting block 342 to move, so that the limiting block 342 extends into the fixed block 341, thereby fixing the handle 33. The cooperation between the fixed block 341 and the handle 33 makes the handle have a blocking effect on the packaging box body 1, making the connection between the two adjacent packaging box bodies 1 more stable and improving the stability during transportation.

[0033] Fourth, when it is necessary to remove the two sets of adjacent stacked packaging box bodies 1, move the adjusting block 345 so that the adjusting block 345 drives the limiting block 342 to move along the round rod 343. When the limiting block 342 moves, it cancels the fixation of the handle 33, so that the handle 33 can be removed from the fixing block 341. By holding the handle 33, the packaging box body 1 can be removed.

[0034] During transportation, the packaging box can be placed individually, stacked to form a wall, or multiple stacked boxes can be placed side by side to form a square block, which facilitates transportation and takes up little space during transportation.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
