Abstract
Description
Technical Field
[0001] This utility model relates to the field of foam box technology, and in particular to a foam box that is easy to stack. Background Technology
[0002] In the fields of logistics transportation and warehousing, foam boxes are widely used for packaging goods such as fresh food and electronic products due to their lightweight, heat insulation and good cushioning performance. Foam boxes are usually made of lightweight foam materials with good heat insulation and cushioning performance, such as expanded polystyrene (EPS) and polyurethane (PU).
[0003] However, traditional foam boxes have a relatively smooth surface, which makes them prone to sliding and misalignment when stacked. Especially during transportation, when vehicles are bumpy and vibrating, the stability of the stacking cannot be guaranteed, which may lead to the movement and damage of goods. Secondly, when foam boxes are stacked at a high height, they are prone to collapse due to the loose overall structure. Therefore, the above-mentioned technical problems need to be solved. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a foam box that is easy to stack.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a foam box that is easy to stack, comprising a box body, wherein a butt plate is fixedly connected to the front end face and one side of the box body, and a butt groove is provided on the rear end face and the other side of the box body to interlock with the butt plate. The butt groove and the butt plate can be spliced perpendicularly to each other. The top of the box body is recessed downward to form a storage groove, and a cover plate is installed on the upper end of the box body. A snap-fit mechanism is provided between the cover plate and the box body.
[0006] Preferably, the snap-fit mechanism includes a snap-fit groove formed between the buffer plate and the housing, and a snap-fit plate is fixedly connected to the corresponding position of the lower end of the cover plate installed at the upper end of the snap-fit groove, and the snap-fit plate can be accurately snapped into the snap-fit groove.
[0007] Preferably, the buffer plate can be inserted into the storage slots in the box and the cover plate, respectively.
[0008] Preferably, both the housing and the cover plate have staggered and equally spaced barrier grooves inside, and barrier plates can be inserted into the barrier grooves.
[0009] Preferably, an arc-shaped groove is provided on the bottom plate of the box, and an arc-shaped block is fixedly connected to the upper surface of the cover plate at a corresponding position, the arc-shaped block being able to closely abut against the inner wall of the arc-shaped groove.
[0010] Preferably, the bottom of the box is provided with positioning grooves at equal intervals around its perimeter, and positioning blocks are fixedly connected to the corresponding positions on the upper surface of the cover plate, so that the positioning blocks can be accurately inserted into the positioning grooves.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the docking plate and docking groove cooperate with each other to facilitate the fixation of foam boxes when stacking, which improves the stability of foam boxes during transportation and realizes the function of preventing goods from moving or being damaged. Furthermore, the arc-shaped block and positioning block cooperate with each other to ensure the accurate position of foam boxes when stacking, which improves the accuracy of foam box stacking and realizes the function of foam boxes being in the same vertical position when stacked at a height. Finally, it solves the problems of easy sliding, misalignment and easy collapse when stacking. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Example: See Figure 1-4This utility model discloses a foam box for easy stacking, comprising a box body 1. A mating plate 2 is fixedly connected to the front end and one side of the box body 1, and a mating groove 5 is provided on the rear end and another side of the box body 1 to interlock with the mating plate 2. The mating groove 5 and the mating plate 2 can be perpendicularly joined together. The top of the box body 1 is recessed downwards to form a storage groove, and a cover plate 7 is installed on the upper end of the box body 1. A snap-fit mechanism is provided between the cover plate 7 and the box body 1, ensuring a tight connection between the foam box and the cover plate 7. The snap-fit mechanism includes a snap-fit groove 3 formed between the buffer plate 4 and the box body 1. A snap-fit plate 12 is fixedly connected to the corresponding position of the cover plate 7 installed at the upper end of the snap-fit groove 3. The snap-fit plate 12 can be accurately snapped into the snap-fit groove 3. Through the snap-fit plate 12 and the snap-fit groove 3, the foam box can achieve a quick and firm connection between the cover plate 7 and the box body 1. The buffer plate 4 can be inserted into the storage slots in the box body 1 and the cover plate 7 respectively. The buffer plate 4 can play a role in buffering and sealing, thereby enhancing the performance of the foam box.
[0020] In this invention, both the box body 1 and the cover plate 7 have staggered and equally spaced barrier grooves 6 inside. Barrier plates can be inserted into the barrier grooves 6 to separate the storage space and improve the flexibility of the foam box. An arc-shaped groove 10 is provided on the bottom plate of the box body 1, and an arc-shaped block 9 is fixedly connected to the corresponding position on the upper surface of the cover plate 7. The arc-shaped block 9 can closely abut against the inner wall of the arc-shaped groove 10. Through the arc-shaped block 9 and the arc-shaped groove 10, the stacking pressure can be effectively distributed, and the stacking stability can be improved. Positioning grooves 11 are provided at equal intervals around the bottom of the box body 1, and positioning blocks 8 are fixedly connected to the corresponding positions around the upper surface of the cover plate 7. The positioning blocks 8 can be accurately inserted into the positioning grooves 11. Through the positioning blocks 8 and the positioning grooves 11, the accuracy and stability of the foam box stacking can be further enhanced, and misalignment and sliding can be prevented.
[0021] Working principle: When using this utility model, foam boxes are first stacked. The docking plate 2 at one corner of box 1 can be vertically inserted into the docking groove 5 of another box 1 to achieve a stable splicing between foam boxes. Then, the cover plate 7 and the snap-fit plate 12 are used to make it easy for the snap-fit plate 12 to be accurately snapped into the snap-fit groove 3, effectively preventing the cover plate 7 from falling off. Then, the buffer plate 4 is inserted into the storage groove to reduce the impact of external forces on the internal items. Then, the barrier groove 6 in the box 1 and the cover plate 7 makes it easy to insert the barrier plate to separate the space and facilitate the classification of items. Then, when the foam boxes are stacked upwards, the arc-shaped block 9 and the positioning block 8 on the cover plate 7 abut against the arc-shaped groove 10 and the positioning groove 11 on the bottom plate of the box 1, respectively, to achieve double positioning to ensure that the stacking is neat and stable, avoid displacement or tilting, and improve stacking efficiency and safety.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
