[0002] Packaging boxes are a convenient, space-saving, and environmentally friendly means of transportation. To facilitate carrying and transport, pull rods are usually installed on packaging boxes. The design of the pull rod should take into account the size and weight of the box, as well as the load-bearing capacity and user experience of the pull rod. Common pull rod configurations include: 1. Fixed pull rod: The pull rod is fixed to the box, allowing the box to be moved directly by hand; 2. Telescopic pull rod: The length of the pull rod can be adjusted according to actual needs, making handling easier.

[0003] Telescopic pull rods are currently the most commonly used pull rod structure for packaging boxes. While they offer the advantage of flexible length adjustment, they also have some drawbacks during operation: Firstly, because the pull rod is a pull-out type, the extension and retraction part is usually quite fragile. Excessive impact, collision, or other improper use can damage the pull rod, affecting its normal use. Secondly, sometimes after prolonged pulling, the internal spring may break and fall out, or the internal parts may become misaligned after the pull rod is extended, preventing it from being pushed back in. These situations can cause the pull rod to be unable to extend or retract properly, inconveniencing the user. Utility Model Content

[0061] To facilitate transportation, rollers 3 are installed on the bottom surface of the box 1, and the box 1 is moved by a pull rod 2. The rollers 3 are located on the rear side of the box 1, and a boss 4 is provided on the bottom surface of the box 1 near the front side. Figure 3 When the box 1 is storing items, the protrusion 4 serves as a bottom support, which facilitates the long-term storage of the box 1 and prevents the roller 3 from being damaged by the single-sided support. On the other hand, it balances the box 1 and facilitates the operation of putting in and taking out items.

[0062] The foldable pull rod 2 is installed with the housing 1 as follows: the pull rod 2 includes an L-shaped fixed rod 21, a first folding rod 22, and a second folding rod 23. The L-shaped fixed rod 21 is divided into a first L-shaped member 211 and a second L-shaped member 212. The first folding rod 22 is divided into a first member 221 and a second member 222. The second folding rod 23 is divided into a third member 231, a fourth member 232, and a crossbar 233. The second folding rod 23 is formed into a U-shaped rod by the third member 231, the fourth member 232, and the crossbar 233. When the pull rod 2 is unfolded, the crossbar 233 serves as a grip.

[0063] The L-shaped fixing rod 21 is connected to the first folding rod 22 and the second folding rod 23 respectively through connectors. The connectors include a first connector and a second connector. The first folding rod 22 is connected to the L-shaped fixing rod 21 through the first connector, and the second folding rod 23 is connected to the first folding rod 22 through the second connector. The first connector is used to restrict the folding of the first folding rod 22 and the second folding rod 23 or to release the folding restriction on the first folding rod 22 and the second folding rod 23. The second connector is used to restrict the folding of the first folding rod 22 and the L-shaped fixing rod 21 or to release the folding restriction on the first folding rod 22 and the L-shaped fixing rod 21.

[0064] The first connecting member includes a first folding joint 24 and a first U-shaped tube 26. The second connecting member includes a second folding joint 25 and a second U-shaped tube 27. The folding structure of the pull rod 2 is as follows: the ends of the first L-shaped rod 211 and the second L-shaped rod 212 of the L-shaped fixing rod 21 are connected to the bottom ends of the first rod 221 and the second rod 222 of the first folding rod 22 respectively through two first folding joints 24. The first folding rod 22 can be folded relative to the L-shaped fixing rod 21 through the first folding joints 24. The top ends of the first rod 221 and the second rod 222 of the first folding rod 22 are connected to the ends of the third rod 231 and the fourth rod 232 of the second folding rod 23 respectively through two second folding joints 25. The second folding rod 23 can be folded relative to the first folding rod 22 through the second folding joints 25.

[0065] In this embodiment, the first folding joint 24 and the second folding joint 25 have the same structure and purpose. The folding joint is a joint that can be folded and connect two rods. It can change the connection angle and allow the two rods to be folded relative to each other. The folding joint can be a U-shaped joint with a built-in folding spring pin. The folding function is achieved by rotating the two U-shaped joints together.

[0066] To increase the stability of the lever 2, a first U-shaped tube 26 and a second U-shaped tube 27 are provided on the first folding rod 22 corresponding to the first folding joint 24 and the second folding joint 25. The first U-shaped tube 26 and the second U-shaped tube 27 have the same structure and purpose. Taking the first U-shaped tube 26 as an example, the first U-shaped tube 26 includes two sleeves 261 and a connecting tube 262 connecting the two sleeves 261. The two sleeves 261 are slidably fitted on the first rod 221 and the second rod 222 respectively. The connecting tube 262 is used for hand grip operation, which facilitates the sliding of the two sleeves 261 on the first rod 221 and the second rod 222.

[0067] The two sleeves 261 are provided with a certain length, which is sufficient to cover the first folding joint 24 when the two sleeves 261 are slidably fitted into the position of the first folding joint 24. The length of the sleeve 261 restricts the folding of the first folding joint 24. By operating the first U-shaped tube 26 and the second U-shaped tube 27, the folding of the first folding rod 22 and the second folding rod 23 of the pull rod 2 can be locked, so that the first folding rod 22 and the second folding rod 23 are kept in the unfolded state, and the pull rod 2 is locked in the use state for transportation, which can prevent the folding rod from being accidentally folded during use.

[0068] To enhance the locking mechanism of the sleeve 261, the first rod 221 and the second rod 222 are respectively equipped with elastic lock cylinders 223 corresponding to the sleeve 261, and a lock hole 263 is provided on the sleeve 261. When the sleeve 261 is fitted onto the first folding joint 24, the elastic lock cylinder 223 pops out and engages in the lock hole 263 to lock the sliding of the sleeve 261. To unlock, simply press the elastic lock cylinder 223 inward to retract it and disengage it from the lock hole 263, allowing the sleeve 261 to slide.

[0069] The rear side of the box 1 is provided with two clearance grooves 14. The L-shaped fixing rod 21 is fixed to the bottom surface and the rear side of the box 1 respectively through its L-shaped structure. The first L-shaped rod 211 and the second L-shaped rod 212 fixed to the rear side are respectively embedded in the two clearance grooves 14. On the one hand, the L-shaped fixing rod 21 is embedded into the box 1 to achieve a flat and beautiful overall appearance. On the other hand, the cooperation between the clearance groove 14 and the L-shaped fixing rod 21 can increase the strength and durability of the box 1, enhance the load strength of the box 1, and ensure the safety of the goods during transportation.

[0070] like Figure 8 The top surface of the box body 1 (i.e., the upper end surface of the box cover 12) is provided with two first slots 15 and two second slots 16, with the two first slots 15 respectively connecting to the two second slots 16. The two second slots 16 are U-shaped grooves, used to place the first U-shaped tube 26 and the second U-shaped tube 27, respectively. The two first slots 15 are vertical grooves, used to place the first rod 221 and the second rod 222 of the first folding rod 22, respectively. A locking piece 17 is provided on the front side of the box body 1, positioned opposite the clearance groove 14 on both sides of the box body 1. When folded, the first folding rod 22 is inserted into the first slot 15, the U-shaped tube is inserted into the second slot 16, and the horizontal bar 233 of the second folding rod 23 engages with the locking piece 17, thus achieving the folding of the pull rod 2. The first slots 15 and the second slots 16 allow the pull rod 2 to be folded and embedded into the box body 1 when not in use, reducing the space occupied by the folded pull rod 2 and facilitating storage.

[0071] like Figure 4-5 When using the pull rod 2 of the packaging box, hold the crossbar 233 of the second folding rod 23 and fold the second folding rod 23 upwards so that it is flush with the first folding rod 22. Pull the second U-shaped tube 27 to slide until the elastic lock core 223 locks the lock hole 263. At this time, the second U-shaped tube 27 is fitted outside the second folding joint 25, restricting the folding of the second folding joint 25. At this time, the pull rod 2 can also be used to pull the box 1 for transportation.

[0072] With the second folding rod 23 unfolded, unfold the first folding rod 22, grasp the crossbar 233 of the second folding rod 23, and continue to fold the first folding rod 22 upwards until it is vertically aligned with the L-shaped fixing rod 21 fixed to the side of the box body 1. Pull the first U-shaped tube 26 to slide until the elastic lock core 223 locks the lock hole 263. At this time, the first U-shaped tube 26 is fitted outside the first folding joint 24, restricting the folding of the first folding joint 24. At this time, the pull rod 2 can be operated to pull the box body 1 for transportation.

[0073] like Figure 1-2 When the pull rod 2 is not in use, press the elastic lock core 223 to release the sliding lock on the first U-shaped tube 26 and the second U-shaped tube 27 in sequence. Then slide the first U-shaped tube 26 and the second U-shaped tube 27 in sequence to release the folding lock on the first folding joint 24 and the second folding joint 25. The first folding rod 22 folds towards the top surface of the box 1 and is embedded in the first slot 15. The second folding rod 23 folds towards the side of the box 1 and is engaged with the clip 17, thus completing the folding and storage of the pull rod 2.

[0074] First embodiment, such as Figure 9-11 .

[0075] This invention provides a usage scenario for a packaging box, which is a packaging box equipped with a folding handle.

[0076] The packaging box can be used for the storage and transportation of the spring pad 5, which includes a splicable elastic element 51 and a base 52. The splicing means that the elastic element 51 can be spliced ​​with the elastic element 51, the elastic element 51 with the base 52, and the base 52 with the base 52.

[0077] Several bases 52 can be stacked, and several elastic components 51 can be stacked. After the bases 52 and elastic components 51 are stacked, the bases 52 and elastic components 51 are placed in the packaging box in sequence. The elastic component 51 is a conical elastic component 51 with a built-in spring. The bases 52 and elastic components 51 are placed alternately in the packaging box to complete the disassembly and storage of the spring bed.
