Description

Technical Field

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

[0002] Currently, tissue products on the market come in a wide variety of sizes, ranging from small portable tissue packs to large household tissue boxes and extra-large commercial tissue rolls, with significant size differences. However, traditional tissue packaging boxes mostly use a fixed-size structure, which has significant limitations: on the one hand, when users need to package tissues of different sizes, boxes that are too small cannot accommodate large tissues, while tissues that are too small will wobble and shift inside a large box, affecting the convenience of the user in taking out the tissues and potentially causing the tissues to scatter, wrinkle, or even be damaged. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a plastic packaging box.

[0004] The objective of this utility model can be achieved through the following technical solution: A plastic packaging box includes a box body and a box lid that snaps onto the box body. The box lid has a paper outlet. Each side of the bottom of the box body has a first slot extending toward the center. The box body has a side plate. The side plate has a pin that is movably connected to the first slot. The bottom of the side plate has a locking block on the side near the center of the box body. The box body has a positioning groove corresponding to the locking block. A lifting assembly is slidably mounted on the side plate. The lifting assembly has an elastic rope for connecting each side plate.

[0005] Preferably, the lifting assembly includes a lifting plate, the bottom of which is provided with a spring that abuts against the box body, the lifting plate is provided with a relief groove corresponding to the side plate, a bracket is provided in the relief groove, the bracket is provided with second slots on both sides that slide and engage with the groove wall of the relief groove, and a vertical groove is provided on the bracket that slides and connects with the side plate.

[0006] Preferably, the bracket has a limiting groove for accommodating the elastic rope.

[0007] Preferably, the bottom of the lifting plate is provided with a fixing block corresponding to the circumference of the spring, the fixing block is provided with a fixing hole corresponding to the spring wire diameter, and the bottom of the box is provided with a retaining ring corresponding to the outer diameter of the spring.

[0008] Preferably, the upper end of the side plate has receiving grooves on both sides, and the receiving grooves are provided with elastic arms.

[0009] The beneficial effects of this utility model are as follows: the side plate limits the position of the tissue paper, preventing it from shaking or shifting inside the box. The first slot on the box body and the pin of the side plate form a movable connection. Combined with the locking mechanism of the locking block, positioning slot and elastic rope, the position of the side plate can be quickly and accurately adjusted and locked, thus adapting to different sizes of tissue paper. At the same time, the lifting component can automatically push according to the remaining amount of tissue paper, always keeping the top of the tissue paper close to the paper outlet, improving the convenience of taking out the tissue paper.

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] See Figures 1 to 8As shown, the structure of this utility model is as follows: a plastic packaging box includes a box body 1 and a box lid 2 that snaps onto the box body 1. The box lid 2 has a paper outlet 3. Each side of the bottom of the box body 1 has a first slot 4 extending towards the center. The box body 1 has a side plate 5 inside, and the side plate 5 has a pin 6 that is movably connected to the first slot 4. A locking block 7 is located on the bottom of the side plate 5 near the center of the box body 1. The box body 1 has a positioning groove 8 corresponding to the locking block 7. A lifting assembly 9 is slidably mounted on the side plate 5, and the lifting assembly 9 has an elastic rope 10 for connecting each side plate 5. Specifically, the box body 1 and the box lid 2 form a closed receiving space, and the paper outlet 3 on the box lid 2 provides a channel for tissue paper extraction. The first slot 4 at the bottom of the box body 1 and the pin 6 of the side plate 5 form a movable connection, similar to a hinge structure, allowing the side plate 5 to rotate slightly and slide along the direction of the first slot 4 to adjust its position. When adjusting the position of side plate 5, pull side plate 5 outwards towards the box body 1. After overcoming the elastic tension of elastic rope 10, side plate 5 rotates around the first slot 4 via pin 6, causing side plate 5 to tilt at a certain angle. This forces the locking block 7 to lift and disengage from the positioning slot 8. At this time, the position of side plate 5 can be freely adjusted. After adjusting to the appropriate position, return side plate 5 to its original position. The tension of elastic rope 10 will pull side plate 5, making the locking block 7 firmly locked into the positioning slot 8. Elastic rope 10 connects each side plate 5 to form a closed loop. When side plate 5 moves, it is stretched and stores potential energy. When returning to its original position, the restoring force pulls side plate 5, keeping side plate 5 vertical and preventing the locking block 7 from disengaging from the positioning slot 8, ensuring the stability of side plate 5. The lifting component 9 on side plate 5 can automatically push the remaining tissue paper upwards according to the amount of tissue paper after extraction, keeping the top of the tissue paper in a convenient extraction position, improving ease of use.

[0024] like Figure 2 , Figure 3 , Figure 5 , Figure 6As shown, the lifting assembly 9 includes a lifting plate 901. A spring 902 abuts against the box body 1 at the bottom of the lifting plate 901. An clearance groove 903 corresponding to the side plate 5 is formed on the lifting plate 901. A bracket 904 is provided inside the clearance groove 903. Second slots 905 on both sides of the bracket 904 are slidably engaged with the groove walls of the clearance groove 903. A vertical sliding groove 906 is formed on the bracket 904, slidably connected to the side plate 5. Specifically, the bottom of the lifting plate 901 abuts against the spring 902. When the tissue is removed, the spring 902 elastically recovers its extension, pushing the lifting plate 901 upwards and pushing the top of the remaining tissue closer to the box body 1. At the paper outlet 3, a certain gap is left between the second slot 905 and the clearance slot 903, allowing the side plate 5 to tilt slightly. The clearance slot 903 on the lifting plate 901 is slidably connected to the bracket 904, and the sliding groove 906 on the bracket 904 is slidably engaged with the side plate 5, forming a double guide structure. During the up-and-down movement of the lifting plate 901 driven by the spring 902, the side plate 5, through its engagement with the sliding groove 906 of the bracket 904, can also provide guide support for the lifting plate 901, ensuring that the lifting plate 901 moves vertically and smoothly, avoiding tilting and jamming, ensuring smooth and unobstructed paper towel extraction, and improving the user experience.

[0025] like Figure 5 As shown, the bracket 904 has a limiting groove 907 for accommodating the elastic rope 10. Specifically, the limiting groove 907 is used to limit the elastic rope 10. During the adjustment of the side plate 5 and the movement of the lifting assembly 9, the elastic rope 10 is in a state of dynamic force and displacement. The limiting groove 907 constrains the radial movement of the elastic rope 10 through the groove wall, preventing it from falling off the bracket 904. Whether the side plate 5 is sliding and adjusted or the lifting plate 901 drives the bracket 904 to move, the elastic rope 10 always slides within the limiting groove 907. The limiting force provided by the groove wall ensures that the elastic rope 10 will not deviate from the predetermined track, thereby maintaining the tension of the elastic rope 10 on each side plate 5, ensuring the stable positioning of the side plate 5 and the reliability of the overall structure, and avoiding structural failure due to the elastic rope 10 falling off.

[0026] like Figure 6 , Figure 8 As shown, the bottom of the lifting plate 901 is provided with a fixing block 11 corresponding to the circumference of the spring 902. The fixing block 11 is provided with a fixing hole 12 corresponding to the wire diameter of the spring 902. The bottom of the box body 1 is provided with a retaining ring 13 corresponding to the outer diameter of the spring 902. Specifically, the coil of one end of the spring 902 is inserted into the fixing hole 12, and the other end is placed in the retaining ring 13 to limit the spring 902. When the spring 902 is compressed, the axial displacement of the spring 902 is limited by the cooperation of the fixing block 11 and the retaining ring 13, ensuring that the elastic force of the spring 902 is stably transmitted to the lifting plate 901 in the vertical direction, thereby improving the reliability and stability of the spring 902 driving the lifting plate 901 to move.

[0027] like Figure 7 As shown, the upper end of the side plate 5 has receiving grooves 14 on both sides, and elastic arms 15 are provided in the receiving grooves 14. Specifically, when the bracket 904 is slidably installed along the side plate 5, it will first contact the fixed end of the elastic arm 15. Due to the elastic deformation capability of the elastic arm 15, under the pressure of the bracket 904, the fixed end drives the elastic arm 15 to retract into the receiving groove 14, forming a clearance space, allowing the bracket 904 to pass smoothly and slide to the predetermined position. After the bracket 904 has completely passed through the elastic arm 15, the elastic arm 15 returns to its original shape by its own elasticity, and its free end protrudes out of the receiving groove 14 again, forming a limiting structure for the bracket 904 and preventing the bracket 904 from falling off the side plate 5.

[0028] In practical use, first adjust the position of the side plate 5 according to the actual size of the tissue paper. Pull the side plate 5 outward from the box body 1. The side plate 5 rotates and tilts in the first slot 4 with the pin 6 as the fulcrum, causing the locking block 7 to disengage from the positioning slot 8. At this time, the side plate 5 can slide freely. After adjusting to the appropriate position, reset the side plate 5. The tension of the elastic rope 10 will pull the side plate 5, so that the locking block 7 is firmly locked into the positioning slot 8, thus completing the fixation of the side plate 5 and adapting to different sizes of tissue paper. After placing the tissue paper and closing the box lid 2, when the user takes out the tissue paper, as the number of tissue paper decreases, the lifting component 9 plays a role and automatically pushes the remaining tissue paper upward, always keeping the top of the tissue paper close to the paper outlet 3 for easy extraction, without the need for manual adjustment.

[0029] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
