Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a quick-release blister packaging box. Background Technology

[0002] Blister packaging boxes are a general term for plastic products that are packaged using appropriate equipment. Essentially, they are formed by heating and softening plastic sheets through a blister forming process, followed by vacuum suction and cooling to create a plastic box shape for packaging, securing, and protecting products.

[0003] The existing literature on blister packaging boxes (CN212829794U) can be referenced. The reference has a partition structure on the surface of the side panel. When multiple blister packaging boxes are stacked together, the partition structure can abut against the side panel of the adjacent blister packaging box, thereby reducing the depth of the previous blister packaging box inserted into the next blister packaging box, that is, reducing the overlap between two adjacent blister packaging boxes.

[0004] In traditional blister packaging boxes, the internal space is usually fixed at the factory, so the internal capacity is also fixed and it is difficult to adjust according to the actual size of the product. Therefore, a quick-release blister packaging box with adjustable box body and lid is designed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-assembly blister packaging box. This invention adjusts the position of the extension box within the base box by sliding the extension box, thereby adjusting the lateral space inside the box. Then, a positioning component fixes the position of the extension box. Simultaneously, the second lid slides inside the first lid as the extension box moves, synchronously adjusting the closure range.

[0027] Reference Figure 1-5 A quick-release blister packaging box includes: a base box 1, an extension box 2, a first lid 3 and a second lid 4. The extension box 2 is slidably installed inside the base box 1. The first lid 3 and the second lid 4 are respectively connected above the base box 1 and the extension box 2. Meanwhile, the second lid 4 is slidably installed inside the first lid 3.

[0028] Specifically, such as Figure 2 As shown, the base box 1 has an opening on the right side for inserting the extension box 2 inside. The side wall and bottom of the extension box 2 abut against the inside of the base box 1. When the extension box 2 slides inside the base box 1, the horizontal space inside the box is adjusted accordingly.

[0029] Specifically, such as Figure 3-4 As shown, an outer rail 10 is connected to the bottom of the base box 1, and an inner rail 15 is connected to the bottom of the extension box 2 via a connecting block 14. The outer rail 10 has an opening on the right side and a movable groove 11 at the bottom. The inner rail 15 fits into the movable groove 11 from the opening on the right side of the outer rail 10.

[0030] Further details can be found by referring to... Figure 5 As shown, a positioning assembly is provided in the inner rail 15. The first screw 17 and the second screw 18 in the positioning assembly are rotatably connected in the inner rail 15. A knob 16 is fixed between the first screw 17 and the second screw 18. A sliding plate 19 is threadedly connected to the outside of the first screw 17 and the second screw 18.

[0031] Furthermore, the threads of screw 17 and screw 2 18 have opposite directions, and both slide plates 19 are slidably installed in the inner rail 15.

[0032] Meanwhile, positioning blocks 20 are fixed to the surfaces of both slide plates 19, and the positioning blocks 20 fit into the side wall of the inner rail 15.

[0033] Specifically, such as Figure 3 As shown, multiple square positioning holes 12 are provided on the side wall of the outer rail 10.

[0034] In this embodiment, rotating the knob 16 drives the screw 17 and screw 18 to rotate. Since the threads are opposite, the two sliding plates 19 outside the screw 17 and screw 18 move in opposite directions during synchronous rotation. When the two sliding plates 19 move away from each other, the two positioning blocks 20 will be inserted into the corresponding two positioning holes 12, thereby fixing the position of the inner rail 15 and correspondingly fixing the position of the extension box 2.

[0035] Furthermore, a pull block 13 is provided at the front end of the extension box 2 to facilitate moving the position of the extension box 2.

[0036] Meanwhile, two foot posts 9 are connected to the bottom left side of the base box 1 and the bottom right side of the extension box 2 respectively, so that the base box 1 and the extension box 2 can be placed stably after adjustment.

[0037] Specifically, such as Figure 2 As shown, the right side of the lid 3 has an opening and the bottom has a movable groove 5. The lid 4 fits into the movable groove 5 through the right side opening of the lid 3.

[0038] Furthermore, mating plates 6 are connected to the surfaces of both the first box cover 3 and the second box cover 4. The two mating plates 6 abut against the side walls of the base box 1 and the extension box 2, respectively. Threaded holes 8 are provided on the side walls of both the base box 1 and the extension box 2. By connecting bolts 7 to the holes on the surface of the mating plates 6 into the threaded holes 8, the first box cover 3 is fixed above the base box 1 and the second box cover 4 is fixed above the extension box 2.

[0039] In this embodiment, when the extension box 2 is adjusted in position, the second box cover 4 slides synchronously inside the first box cover 3, and the upper closed range is adjusted accordingly, so that the internal space of the box can be quickly adjusted and installed.

[0040] Working principle: When using this utility model, the extension box 2 is slidably installed inside the base box 1, and the base box 1 and the extension box 2 are respectively connected to the bottom of the outer rail 10 and the inner rail 15. The inner rail 15 is slidably installed in the outer rail 10. When the extension box 2 slides inside the base box 1, the horizontal space inside the box is adjusted accordingly, and the position of the inner rail 15 is adjusted synchronously. The inner rail 15 is provided with a positioning component. When it moves to the appropriate position, the two positioning blocks 20 in the positioning component are inserted into the positioning holes 12 on the side wall of the outer rail 10 to complete the position fixation. The box cover 3 and the box cover 4 are connected to the top of the base box 1 and the extension box 2 by bolts 7. When the position of the extension box 2 is adjusted, the box cover 4 slides synchronously in the box cover 3, thereby adjusting the sealing range of the box cover, so as to quickly complete the adjustment of the internal space of the packaging box.
