Technical Field

[0001] This utility model relates to the field of packaging carton technology, specifically to a pressure-resistant packaging carton. Background Technology

[0002] Cardboard boxes are made of paper products and are used to package various items. Cardboard boxes are widely used in goods transportation and material handling due to their advantages such as low cost, ease of sealing, and cleanliness. Packaging cardboard boxes have become an indispensable part of modern logistics, serving the purpose of containing and protecting transported goods. For some large or valuable items, packaging cardboard boxes also need to have sufficient compressive strength.

[0003] Currently, pressure-resistant cardboard boxes mainly consist of a frame made up of multiple support rods inside the box. However, the frame needs to be compatible with the cardboard box, making it inconvenient to store and adjust. It also lacks adaptability to different sizes of cardboard boxes and reusability. There is an urgent need to design a pressure-resistant packaging cardboard box to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a pressure-resistant packaging carton to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown in the figure, this utility model provides a pressure-resistant packaging carton.

[0022] The device includes a box body 1, a box cover 2 on the top of the box body 1, support blocks 3 at the four corners of the bottom of the box body 1, a telescopic rod 4 between each pair of adjacent support blocks 3, an insert rod 5 on the top of each of the four support blocks 3, a support rod 6 inserted into each of the four insert rods 5, a sliding rod 7 slidably and rotatably fitted inside the support rod 6, a fixing component 8 between the support rod 6 and the sliding rod 7, and an adjusting rod 9 between each pair of adjacent support rods 6. The adjusting rod 9 includes a first rod body 10 rotatably fitted on the top of one side of one support rod 6 and a second rod body 11 rotatably fitted on the bottom of one side of the other support rod 6. The second rod body 11 slidably fitted inside the first rod body 10. A positioning pin 24 is provided on the top of the first rod body 10, and multiple positioning holes 25 are provided on the top of the second rod body 11. The positioning pin 24 engages with the multiple positioning holes 25 respectively.

[0023] Reference Figure 3 In this embodiment, both the top of the support rod 6 and the bottom of the slide rod 7 are provided with insertion holes 12, and the insertion rod 5 is inserted into the insertion holes 12. Through the provided insertion holes 12, the insertion rod 5 can be inserted into the insertion holes 12 for connection, and the support block 3 can be assembled at the top of the support rod 6 and at the bottom of the slide rod 7.

[0024] Reference Figure 3In this embodiment, the fixing component 8 includes a fixing rod 13 installed in the support rod 6, a sliding groove 14 formed in the slide rod 7, and multiple fixing slots 15 formed in the slide rod 7. The fixing rod 13 and the sliding groove 14 are slidably engaged, and the sliding groove 14 is connected to the multiple fixing slots 15. When the slide rod 7 is pulled to slide within the support rod 6 using the fixing rod 13, the fixing rod 13 will slide within the sliding groove 14, causing the slide rod 7 to move out of the support rod 6. After adjusting to a suitable length, rotating the slide rod 7 allows the fixing rod 13 to enter the corresponding fixing slot 15, thus fixing the slide rod 7.

[0025] Reference Figure 4 In this embodiment, the support block 3 is L-shaped, and the telescopic rod 4 includes a first cylinder 16 installed at one end of the support block 3, a second cylinder 17 installed at the other end of the support block 3, and a third cylinder 18 slidably fitted around the second cylinder 17. The first cylinder 16 is slidably fitted inside the second cylinder 17, and a limiting rod 19 is installed inside the third cylinder 18. Both the first cylinder 16 and the second cylinder 17 have limiting grooves 20, and the limiting rod 19 is slidably fitted with the two limiting grooves 20. By using the first cylinder 16, the second cylinder 17, and the third cylinder 18, when the four support blocks 3 are pulled, the first cylinder 16 can be moved out of the second cylinder 17. At this time, the limiting groove 20 on the first cylinder 16 will drive the limiting rod 19, causing the limiting rod 19 to drive the third cylinder 18, so that the third cylinder 18 moves along the circumference of the second cylinder 17, allowing the first cylinder 16, the second cylinder 17, and the third cylinder 18 to extend and retract.

[0026] Reference Figure 4 In this embodiment, both ends of the support block 3 are provided with storage grooves 21, and the storage grooves 21 are slidably engaged with the third cylinder 18. Through the storage grooves 21, when the four support blocks 3 are pushed, the first cylinder 16 can move into the second cylinder 17, and the two ends of the third cylinder 18 can enter the two storage grooves 21 respectively, allowing the first cylinder 16, the second cylinder 17 and the third cylinder 18 to retract to the maximum extent.

[0027] Reference Figure 1-2 In this embodiment, handle rings 22 are provided on both opposite outer sides of the lid 2, and grooves 23 are provided on both opposite outer sides of the body 1. The handle rings 22 correspond to the grooves 23. By inserting the handle rings 22, the grooves 23 can be pulled, and the body 1 and lid 2 can be lifted by the handle rings 22.

[0028] Working principle: In use, first, pull the four support blocks 3 according to the size of the box 1, causing the four telescopic rods 4 to extend and retract. After adjusting to the appropriate position, place the box 1. The four support blocks 3 should correspond to the four corners at the bottom of the box 1. Then, pull the four support rods 6, causing the four adjusting rods 9 to extend and retract. The second rod 11 will move out from the first rod 10. After adjusting the four support rods 6 to correspond to the four support blocks 3, use the positioning pins 24 to insert into the corresponding positioning holes 25 to fix the first rod 10 and the second rod 11, so that the adjusting rods 10 and 11 together form an adjustable rod. The section rod 9 is inclined for support, and then the four support rods 6 are respectively inserted into the four insertion rods 5. The support block 3 is assembled with the support rods 6. At this time, the four support rods 6 will support the box body 1. The first rod body 10 and the second rod body 11 fix the support and restrict the telescopic rod 4, so that the telescopic rod 4 cannot extend or retract. The extension slide rod 7 moves out of the support rod 6, which can adjust the support height of the support rod 6 so that the height of the support rod 6 is adapted to the box body 1. Then, the corresponding support block 3 is assembled on the top of the support rod 6, and the box cover 2 is closed. Conversely, the support rod 6 and the support block 3 can be disassembled and taken out for folding or storage.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
