Description

Technical Field

[0001] The utility model relates to the technical field of packaging cartons, in particular to a heat-insulating packaging carton. Background Art

[0002] With the rapid development of the modern logistics industry, packaging cartons, as an important tool for the transportation and storage of goods, have increasingly diversified functional requirements. Insulated packaging cartons use advanced insulation materials and unique design structures to ensure that the temperature inside the box remains stable for a certain period of time. This type of carton is usually made of multi-layer composite materials. The inner layer is an insulation material, such as aluminum foil, foam plastic or aerogel, and the outer layer is waterproof and wear-resistant paper or plastic material. Through reasonable material selection and structural design, the thermal insulation packaging carton can effectively isolate the influence of the external temperature and provide a relatively stable temperature environment for the items in the box. However, the traditional thermal insulation packaging carton is inconvenient to install and disassemble the internal packaging box, which makes it difficult to disassemble and clean the internal packaging box after contamination, and replacement will cause waste of resources, so there are certain disadvantages.

[0027] An L-shaped slide groove 401 is provided at the top of the fixed block 4, a cavity 402 is provided inside the fixed block 4, a movable plate 8 is installed at one end inside the cavity 402, a movable rod 9 is installed on the outer surface of the movable plate 8, a return spring 10 is installed on the outer ring surface of the movable rod 9, a slide groove 801 is provided at the top of the movable plate 8, a slide rod 11 is installed between the inner side walls of the slide groove 801, a slider 12 is installed on the outer ring surface of the slider 11, and a push block 13 is installed on the top of the slider 12.

[0028] Specifically, refer to Figure 2 and Figure 3 The inner wall size of the heat preservation box 1 matches the outer size of the heat preservation box 7, and the heat preservation box 7 is taken out or put into the heat preservation box 1 through the hidden handles 701 on both sides of the interior, so that the heat preservation box 7 is conveniently taken out from the interior of the heat preservation box 1 for cleaning.

[0029] Furthermore, the outer side surface of the movable plate 8 is slidably connected to the inner wall of the cavity 402, and the end of the movable rod 9 away from the movable plate 8 passes through the inner wall of the return spring 10 and then passes through the fixed block 4 to extend to the interior of the insulation box 1, thereby ensuring that by pushing the movable plate 8 to move, one end of the movable rod 9 can be synchronously driven to enter the interior of the insulation box 1 and compress the return spring 10.

[0030] Furthermore, the size of the outer ring surface of the movable rod 9 matches the size of the inner wall of the limiting hole 702, and the outer ring surface of the movable rod 9 is slidingly connected to the inner wall of the limiting hole 702, thereby ensuring that when one end of the movable rod 9 enters the interior of the insulation box 1, it is simultaneously connected to the interior of the limiting hole 702, thereby fixing the insulation box 7 inside the insulation box 1.

[0031] Furthermore, the outer side surface of the slider 12 is slidably connected to the inner wall of the L-shaped slide groove 401, and the slider 12 slides to the top along the L-shaped slide groove 401 and then slides to the right to limit the movable rod 9 connected to the inside of the limiting hole 702, thereby ensuring that the movable rod 9 is limited and the insulation box 7 is fixed.

[0032] For details, please refer to Figure 4 and Figure 5 The interior of the slider 12 is slidably connected to the outer ring surface of the slide rod 11, and when the slider 12 is located on the left side of the slide rod 11, the movable rod 9 can be pushed to move, and when the slider 12 is located on the right side of the slide rod 11, the movable rod 9 can be limited, thereby ensuring that the slider 12 slides on the outer ring surface of the slide rod 11, making it easy to slide the slider 12 along the L-shaped slide groove 401 to the top and then slide right to limit the movable rod 9, which is convenient to operate.

[0033] The working process of the utility model: using an insulated packaging carton designed by the present invention, during the use of the insulated packaging carton, the two rotating handles 3 on the outside of the insulated box 1 are used to facilitate the movement of the insulated box 1, and the four sets of anti-collision guard strips 2 are provided to effectively avoid bumps during transportation, and a sealing pad 6 is provided on the outer edge of the insulated box 1 to increase the sealing between the box cover 5, and the insulated box 7 is taken out or put into the insulated box 1 through the hidden handles 701 on both sides of the inside, so that the insulated box 7 is taken out from the inside of the insulated box 1 for cleaning, and the slider 12 can be pushed by the push block 13 to slide inside the L-shaped slide groove 401, and the slider 12 slides along the L-shaped When the slide groove 401 slides to the top, it simultaneously drives the movable plate 8 to move. The movement of the movable plate 8 simultaneously drives one end of the movable rod 9 to enter the interior of the insulation box 1 and compress the reset spring 10. When one end of the movable rod 9 enters the interior of the insulation box 1, it is simultaneously connected to the interior of the limiting hole 702, thereby fixing the insulation box 7 inside the insulation box 1. After the slider 12 slides to the top along the L-shaped slide groove 401 and then slides to the right, it can limit the movable rod 9 connected to the interior of the limiting hole 702, so that the insulation box 7 will not move inside the insulation box 1.
