Description

Technical Field

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

[0002] A packaging box is a container used to package products, preventing damage during transportation and storage. Packaging boxes often have a certain degree of rigidity or semi-rigidity to protect the products during transport. The shape and size of the packaging box can be customized according to the characteristics and needs of the product. Common geometric shapes include cuboids, cubes, and cylinders. The materials of packaging boxes usually include cardboard, metal, plastic, wood, etc., and different materials have different properties and uses.

[0003] Traditional packaging boxes have a fixed structure, which often requires custom-made boxes of different sizes for items of different dimensions, resulting in relatively low flexibility in use.

[0004] Therefore, a packaging box with variable height is provided to address the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a packaging box with variable height to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a variable height packaging box, comprising a packaging box body, wherein symmetrically arranged limiting grooves are provided inside the packaging box body, and two sets of receiving grooves are provided on both sides of the packaging box body. A lifting box is installed inside the packaging box body, and limiting blocks are fixedly installed on both sides of the lifting box. The two sets of limiting blocks are slidably connected to the two sets of limiting grooves respectively. Two sets of first female buckles are installed on both sides of the lifting box, two sets of limiting mechanisms are installed on both sides of the packaging box body, and two sets of second female buckles are installed on both sides of the lifting box.

[0008] Furthermore, a top cover is installed on the upper surface of the lifting box.

[0009] Furthermore, the limiting mechanism includes a fixing block, which is installed on the outer surface of the packaging box body.

[0010] Furthermore, the limiting mechanism also includes an extension bag, which is installed on one side of the fixing block.

[0011] Furthermore, the limiting mechanism also includes a support frame, and one end of the extended bag is fixedly mounted with the support frame.

[0012] Furthermore, the limiting mechanism also includes a male buckle, and a male buckle is fixedly installed at one end of the support frame.

[0013] This utility model has the following beneficial effects:

[0014] (1) This utility model achieves the purpose of changing the height of the usable space inside the packaging box by pushing the lifting box up or down along the limiting slide groove. After the lifting box is moved to the appropriate position, the first female buckle on both sides and the limiting mechanism on both sides of the main body of the packaging box can cooperate with each other to fix the position of the lifting box. By picking up the support frame and then fastening the male buckle on the first female buckle, when the male buckle is fastened on the first female buckle, the position of the support frame is against the corner of the main body of the packaging box. The support frame achieves the effect of further supporting the lifting box. The four limiting mechanisms are fastened on the four sets of first female buckles respectively, thus completing the position fixation of the lifting box, thereby achieving the effect of adjusting the height of the packaging box and adjusting the accommodating space of the packaging box, thereby improving the flexibility of use.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 4 As shown, this utility model is a variable height packaging box, including a packaging box body 1. The packaging box body 1 has symmetrically opened limiting grooves 2 inside. The packaging box body 1 has two sets of receiving grooves 3 on both sides inside. The packaging box body 1 has a lifting box 4 installed inside. The lifting box 4 has limiting blocks 5 fixedly installed on both sides. The two sets of limiting blocks 5 are slidably connected to the two sets of limiting grooves 2 respectively. The lifting box 4 has two sets of first female buckles 6 installed on both sides. The packaging box body 1 has two sets of limiting mechanisms 8 installed on both sides. The lifting box 4 has two sets of second female buckles 9 installed on both sides.

[0025] A top cover 7 is installed on the upper surface of the lifting box 4;

[0026] The limiting mechanism 8 includes a fixing block 801, which is installed on the outer surface of the packaging box body 1;

[0027] The limiting mechanism 8 also includes an extension bag 802, which is installed on one side of the fixing block 801;

[0028] The limiting mechanism 8 also includes a support frame 803, and the support frame 803 is fixedly installed at one end of the extended cloth bag 802;

[0029] The limiting mechanism 8 also includes a male buckle 804, and the male buckle 804 is fixedly installed at one end of the support frame 803;

[0030] When the height of the packaging box needs to be adjusted, the limiting blocks 5 on both sides of the lifting box 4 are slidably connected to the limiting grooves 2 inside the main body 1 of the packaging box. This provides guidance for the vertical movement of the lifting box 4. The operator can push the lifting box 4 up or down along the limiting grooves 2 to change the height of the usable space inside the packaging box. After the lifting box 4 is moved to the appropriate position, the first female buckles 6 on both sides and the limiting mechanisms 8 on both sides of the main body 1 of the packaging box can cooperate to fix the position of the lifting box 4. By lifting the support frame 803 and then fastening the male buckle 804 on the first female buckle 6, the support frame 803 is positioned against the corner of the main body 1 of the packaging box. The support frame 803 further supports the lifting box 4. By fastening the four limiting mechanisms 8 on the four sets of first female buckles 6 respectively, the position of the lifting box 4 is fixed, thereby achieving the effect of adjusting the height of the packaging box and adjusting the accommodating space of the packaging box, thus improving the flexibility of use.

[0031] When in use, when it is necessary to adjust the height of the packaging box, the limiting blocks 5 on both sides of the lifting box 4 are slidably connected to the limiting groove 2 inside the main body 1 of the packaging box. This provides a guide for the up and down movement of the lifting box 4. The operator can push the lifting box 4 up or down along the limiting groove 2 to change the height of the available space inside the packaging box. After the lifting box 4 is moved to the appropriate position, the first female buckles 6 on both sides and the limiting mechanisms 8 on both sides of the main body 1 of the packaging box can cooperate to fix the position of the lifting box 4. By picking up the support frame 803 and then fastening the male buckle 804 on the first female buckle 6, when the male buckle 804 is fastened on the first female buckle 6, the position of the support frame 803 is against the corner of the main body 1 of the packaging box. The support frame 803 achieves the effect of further supporting the lifting box 4. The four limiting mechanisms 8 are fastened on the four sets of first female buckles 6 respectively, thus completing the position fixation of the lifting box 4, thereby achieving the effect of adjusting the height of the packaging box and adjusting the accommodating space of the packaging box, thereby improving the flexibility of use.

[0032] By disassembling the male buckle 804 on the four sets of limiting mechanisms 8, pushing the lifting box 4 downward to reset, and then repeating the operation of the four limiting mechanisms 8 as described above, inserting them into the interior of the four sets of second female buckles 9, the packaging box can be restored.

[0033] The four sets of receiving slots 3 provide storage space for the four sets of first female buckles 6.
