Description

Technical Field

[0001] This utility model relates to the field of automotive parts packaging technology, specifically a cardboard box with a lining of pearl cotton. Background Technology

[0002] In automotive parts packaging, the combination of pearl cotton and cardboard boxes provides efficient and reliable protection for the components. During vehicle operation and transportation, parts are subjected to various vibrations and impacts. Pearl cotton has excellent cushioning properties, effectively absorbing and dispersing this energy, protecting the parts from damage. For example, wrapping critical components such as engine blocks and transmissions with pearl cotton during transportation can significantly reduce the risk of internal structural damage caused by bumps and jolting.

[0003] In existing technologies, such as the novel thermal insulation corrugated cardboard disclosed in Publication No. CN222771222U, a paper core, aluminum foil, pearl cotton, and an outer cardboard are included. The inner side of the paper core is aluminum foil, and the corrugated cardboard has two layers of paper core and two layers of aluminum foil. The outer side of the paper core is the outer cardboard, and pearl cotton is placed between the aluminum foil and the outer cardboard. The paper core is corrugated, and the pearl cotton and aluminum foil are bonded together. The paper core and aluminum foil, as well as the paper core and outer cardboard, are bonded with adhesive. The outer cardboard is made of hard cardboard. By placing pearl cotton and aluminum foil in the middle of the paper core, it improves the thermal insulation performance of the corrugated cardboard box, providing excellent insulation for packaged and transported goods. The double-layered paper core and outer hard cardboard effectively ensure the stability and strength of the corrugated cardboard box, making it suitable for packaging and transporting items requiring insulation.

[0004] Existing cardboard boxes improve their insulation performance by placing pearl cotton and aluminum foil in the middle of the paper core, which can play a good role in keeping packaged and transported goods warm. However, their cushioning performance is insufficient, and the corner windows are easily scratched or broken due to vibration during transportation. When stacked, they lack positioning structures and are prone to sliding and displacement, causing collisions. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technologies have insufficient cushioning performance, the corner windows are easily scratched or broken due to vibration during transportation, and there is a lack of positioning structure when stacking, which makes them prone to sliding and displacement, causing collisions.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A cardboard box with a liner of pearl cotton includes a first protective cardboard, a protective component for protecting the workpiece is arranged horizontally on the side wall of the first protective cardboard, and an auxiliary component for further protecting the workpiece is provided on one side of the first protective cardboard.

[0009] The protective component includes two sets of horizontal pearl cotton, both sets of which are horizontally placed on the side wall of the first protective cardboard. Two sets of vertical pearl cotton are installed vertically on the right side of the first protective cardboard, and each set of vertical pearl cotton has two fixing holes inside.

[0010] As a further improvement of this utility model: two limiting grooves are opened inside the two sets of transverse pearl cotton, and automotive glass is inserted into the two fixing holes. The automotive glass is connected to the limiting grooves by insertion.

[0011] As a further improvement of this utility model: the auxiliary component includes a second protective cardboard, which is connected to one side of the first protective cardboard.

[0012] As a further improvement of this utility model, two positioning holes are symmetrically opened on the outer walls of both the second protective cardboard and the first protective cardboard.

[0013] As a further improvement of this utility model: a limiting rod is fixed to the side wall of the second protective cardboard, and a rubber ring is fixed to the end of the limiting rod.

[0014] As a further improvement of this utility model, one side of the limiting rod is inserted into a connecting hole opened on the first protective cardboard.

[0015] As a further improvement of this utility model, the interior of the connecting hole is provided with a positioning groove that is interference-fitted with the rubber ring.

[0016] As a further improvement of this utility model: the sidewalls of both the horizontal and vertical pearl cotton are coated with an adhesive layer, and a release paper is movably connected to one side of the adhesive layer.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses fixing holes opened on the vertical pearl cotton to play a positioning role, thereby effectively reducing the displacement of the car glass. The upper and lower ends of the car glass are connected to the horizontal pearl cotton. Through the limiting groove opened in the horizontal pearl cotton, the upper and lower ends of the car glass can be inserted into the horizontal pearl cotton, thereby limiting the position of the car glass.

[0019] 2. This utility model adheres the adhesive layer to the inner wall of the first protective cardboard, thereby fixing the two sets of horizontal and vertical pearl cotton. In this way, the car glass can be limited, effectively reducing the possibility of collision caused by sliding and displacement, and can stably secure the car glass. The horizontal and vertical pearl cotton themselves have a certain cushioning effect, thus achieving protection for the car glass.

[0020] 3. This utility model uses the connecting hole on the inner wall of the first protective cardboard to align and insert the limiting rod on the second protective cardboard into the connecting hole, so that the rubber ring on the limiting rod and the positioning groove achieve an interference fit, thereby assembling the second protective cardboard onto the first protective cardboard, which can effectively prevent the surface of the car glass from being scratched.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0030] Example 1

[0031] Please see Figures 1-5 This is the first embodiment of the present invention.

[0032] This embodiment provides a cardboard box with a liner made of pearl cotton, including a first protective cardboard 1. A protective component for protecting the workpiece is arranged horizontally on the side wall of the first protective cardboard 1, and an auxiliary component for further protecting the workpiece is provided on one side of the first protective cardboard 1.

[0033] The protective component includes two sets of horizontal pearl cotton 2. Both sets of horizontal pearl cotton 2 are horizontally placed on the side wall of the first protective cardboard 1. Two sets of vertical pearl cotton 21 are installed vertically on the right side of the first protective cardboard 1. Each set of vertical pearl cotton 21 has two fixing holes 22 inside.

[0034] Specifically, each of the two sets of transverse pearl cotton 2 has two limiting grooves 23 inside, and each of the two fixing holes 22 has a car glass 24 inserted into it, and the car glass 24 is connected to the limiting groove 23.

[0035] Furthermore, the limiting groove 23 opened in the transverse pearl cotton 2 allows the upper and lower ends of the car glass 24 to be inserted into the transverse pearl cotton 2, thereby limiting the car glass 24.

[0036] Specifically, the sidewalls of both the horizontal pearl cotton 2 and the vertical pearl cotton 21 are coated with an adhesive layer 5, and a release paper 6 is movably connected to one side of the adhesive layer 5.

[0037] Furthermore, the adhesive layer 5 is aligned with the inner wall of the first protective cardboard 1 and adhered thereto, thereby fixing the two sets of horizontal pearl cotton 2 and vertical pearl cotton 21, effectively reducing the possibility of collision caused by sliding displacement.

[0038] In use, place the first protective cardboard 1 in a suitable position, and connect the left and right sides of the car glass 24 to be transported to the vertical pearl cotton 21 respectively. The fixing holes 22 on the vertical pearl cotton 21 can play a positioning role, thereby effectively reducing the displacement of the car glass 24. Then, connect the upper and lower ends of the car glass 24 to the horizontal pearl cotton 2. The limiting grooves 23 in the horizontal pearl cotton 2 allow the upper and lower ends of the car glass 24 to be inserted into the horizontal pearl cotton 2, thereby securing the car glass 24. The limiting mechanism involves peeling off the release paper 6 from the adhesive layer 5 coated on the horizontal pearl cotton 2 and the vertical pearl cotton 21, and then adhering the adhesive layer 5 to the inner wall of the first protective cardboard 1. This fixes the two sets of horizontal pearl cotton 2 and vertical pearl cotton 21, thereby limiting the movement of the car glass 24, effectively reducing the possibility of collisions caused by sliding and displacement, and stably securing the car glass 24. The horizontal pearl cotton 2 and vertical pearl cotton 21 themselves have a certain cushioning effect, thus protecting the car glass 24.

[0039] In summary, when using the cardboard box with the EPE foam lining, the adhesive layer 5 is aligned with the inner wall of the first protective cardboard 1 and adhered, thereby fixing the two sets of horizontal EPE foam 2 and vertical EPE foam 21. This effectively reduces the possibility of collisions caused by sliding and displacement, and can stably secure the car glass 24. The horizontal EPE foam 2 and vertical EPE foam 21 themselves have a certain cushioning effect, thus protecting the car glass 24.

[0040] Example 2

[0041] Please see Figures 1-5 This is the second embodiment of the present utility model.

[0042] Specifically, the auxiliary component includes a second protective cardboard 4, which is connected to one side of the first protective cardboard 1. Both the second protective cardboard 4 and the first protective cardboard 1 have two symmetrical positioning holes 3 on their outer walls.

[0043] Furthermore, the positioning hole 3 facilitates the subsequent stacking and positioning of the carton, making it easy to use.

[0044] Specifically, a limiting rod 41 is fixed to the side wall of the second protective cardboard 4, a rubber ring 42 is fixed to the end of the limiting rod 41, and a connecting hole 43 opened on the first protective cardboard 1 is inserted into one side of the limiting rod 41.

[0045] Furthermore, the limiting rod 41 on the second protective cardboard 4 is aligned with the connecting hole 43 on the inner wall of the first protective cardboard 1 and inserted.

[0046] Specifically, the interior of the connecting hole 43 is provided with a positioning groove 44 that is interference-fitted with the rubber ring 42.

[0047] Furthermore, the rubber ring 42 on the limiting rod 41 and the positioning groove 44 are interference-fitted, thereby assembling the second protective cardboard 4 onto the first protective cardboard 1, which can effectively prevent the surface of the car glass 24 from being scratched.

[0048] In use, the limiting rod 41 on the second protective cardboard 4 is aligned with the connecting hole 43 on the inner wall of the first protective cardboard 1 and inserted, so that the rubber ring 42 on the limiting rod 41 and the positioning groove 44 achieve an interference fit, thereby assembling the second protective cardboard 4 onto the first protective cardboard 1. This can effectively prevent the surface of the car glass 24 from being scratched, and the positioning hole 3 facilitates the subsequent stacking and positioning of the carton, making it easy to use.

[0049] In summary, when using the cardboard box with the EPE foam lining, the adhesive layer 5 is aligned with the inner wall of the first protective cardboard 1 and adhered, thereby fixing the two sets of horizontal EPE foam 2 and vertical EPE foam 21. This effectively reduces the possibility of collisions caused by sliding and displacement, and can stably secure the car glass 24. The horizontal EPE foam 2 and vertical EPE foam 21 themselves have a certain cushioning effect, achieving protection for the car glass 24. Furthermore, by assembling the second protective cardboard 4 onto the first protective cardboard 1, scratches on the surface of the car glass 24 can be effectively prevented.
