[0009] In one embodiment, the plastic turnover box further includes a one-way valve located within the inflation air passage, the one-way valve being used to restrict the flow of gas from the first air hole to the second air hole.

[0010] In one embodiment, a bearing groove is recessed on the upper end face of the bearing plate, and the bearing groove forms the bearing position.

[0023] Turnover boxes are made of plastic and are mainly used for product turnover and product packaging. They are lightweight and stackable.

[0024] However, existing general-purpose turnover boxes are prone to causing products to move around inside the box during transportation, resulting in collisions with the box and damage to the products. While specialized turnover boxes can reduce the risk of products colliding with the box, they can only be used for transporting a single type of product, thus having a narrow scope of application.

[0025] This utility model proposes a plastic turnover box, which aims to improve the problem that existing turnover boxes cannot simultaneously ensure the safety and applicability of product transportation.

[0026] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the plastic turnover box 100 includes a box body 1 and a plurality of support plates 2. The box body 1 has a receiving cavity and the upper end is open to expose the receiving cavity. The plurality of support plates 2 are spaced apart in the receiving cavity in the vertical direction. Each support plate 2 is detachably connected to the inner sidewall of the box body 1. The lower end of the support plate 2 is provided with a first air bladder 21, which is elastically arranged. The upper end of the first air bladder 21 has at least one support position for supporting products.

[0027] In the technical solution of this utility model, when the plastic turnover box 100 is needed to transport products, firstly, one of the bearing plates 2 is installed into the accommodating cavity of the box body 1. Then, the product is placed on the bearing position on the bearing plate 2. At this time, another bearing plate 2 is installed into the accommodating cavity, and the bearing plate 2 is positioned above the bearing plate 2 carrying the product. At this time, the first airbag 21 provided below the bearing plate 2 can abut against the product and deform under the pressure of the product, so that the shape of the first airbag 21 can fit the shape of the product. At this time, the first airbag 21 can... The elastic design of the first airbag 21 not only effectively buffers the vibration and impact on the product during transportation, but also adapts to the shape of the product to provide a more fitting and comprehensive protection. Thus, the first airbag 21 can clamp the product together with the support plate 2 that carries the product. During transportation, the elastic deformation of the first airbag 21 effectively buffers the vibration and impact on the product, preventing the product from being damaged by collision, improving the transportation safety of the plastic turnover box 100, and making the plastic turnover box 100 suitable for products of various shapes and sizes, greatly improving its versatility and practicality.

[0028] It is understood that since each of the bearing plates 2 is detachably connected to the inner wall of the box 1, this utility model does not limit the specific number of the bearing plates 2 or the distance between two adjacent bearing plates 2. In actual installation, the number and spacing of the bearing plates 2 can be flexibly adjusted according to the actual size and quantity of the product to meet the transportation needs in different scenarios.

[0029] Similarly, this utility model does not limit the specific number of bearing positions formed on each of the bearing plates 2. In actual installation, the specific number and layout position of the bearings formed on the bearing plates 2 can be set according to the specific shape and size of the product to ensure that the product can be placed stably and safely on the bearing plates 2.

[0030] It should be noted that during the use of the plastic turnover box 100, in order to avoid the first airbag 21 exerting excessive pressure on the product, which would cause the first airbag 21 to not only fail to provide sufficient cushioning for the product, but also easily damage the product due to excessive pressure, in one embodiment of the present invention, the first airbag 21 includes a plurality of deformable parts 211 arranged at intervals in the horizontal and / or vertical directions, and the plurality of deformable parts 211 are at least partially offset from the bearing position in the vertical direction.

[0031] With this configuration, when the product is placed on the support position, the multiple deformation portions 211 can disperse the pressure exerted by the product on the first airbag 21, preventing excessive local pressure that could damage the product. Simultaneously, because the multiple deformation portions 211 are at least partially offset from the support position vertically, when the first airbag 21 deforms under product pressure, it can more evenly conform to the product surface, further improving the cushioning and protection effect.

[0032] It is understood that the present invention does not limit the specific formation of the plurality of deformable parts 211. In one embodiment of the present invention, the first airbag 21 may be composed of a plurality of airbags, which are spaced apart in the horizontal and vertical directions. Thus, four airbags arranged adjacent to each other in the horizontal and vertical directions can jointly correspond to one of the bearing positions to jointly compress and fit the product placed on the bearing position, thereby neutralizing the pressure on the product while ensuring the cushioning and protection effect of the product.

[0033] In another embodiment of this utility model, the first airbag 21 is provided with at least one connecting portion 4122. The connecting portion 4122 is arranged vertically and upwards corresponding to the bearing position, and is used to connect the two ends of the first airbag 21 vertically and upwards. The connecting portion 4122 defines a deformable portion 211 on at least two side walls adjacent to the housing 1 in the horizontal and vertical directions. With this arrangement, since the connecting portion 4122 is arranged corresponding to the bearing position, when the product is placed on the bearing position, the connecting portion 4122 can support, distribute pressure, and to a certain extent limit the deformation of the first airbag 21 above the bearing position. This allows the first airbag 21 to deform more stably when squeezed by the product, and the deformable portion 211 can more accurately conform to the product surface, thereby ensuring sufficient cushioning protection for the product while avoiding damage to the product due to excessive local pressure. Furthermore, this arrangement also enhances the overall structural strength of the first airbag 21, improving its service life and reliability.

[0034] Furthermore, in practical applications, the connection part 4122 can also limit and guide the deformation of the first airbag 21, so that the first airbag 21 can deform in the expected way when squeezed by the product, thereby better protecting the product.

[0035] Of course, this utility model does not limit the specific connection form of the connecting part 4122. In one embodiment of this utility model, the connecting part 4122 can be configured as a connecting post, which extends vertically. In another embodiment of this utility model, the connecting part 4122 can also be configured as an adhesive, so that the adhesive can be respectively bonded to the first airbag 21 at its vertically upward ends. In other embodiments of this utility model, the connecting part 4122 can also be configured in other forms, and can be selected according to the requirements in actual settings.

[0036] It is understood that when there are multiple bearing positions, there are also multiple connecting parts 4122, and each connecting part 4122 corresponds to one bearing position in the vertical direction. Thus, the multiple connecting parts 4122 can be divided into three parts. In the first part, the connecting parts 4122 define a deformation part 211 with the two side walls of the box 1 in the horizontal and vertical directions. In the second part, two adjacent connecting parts 4122 in the horizontal direction can define a deformation part 211 with one side wall of the box 1 in the vertical direction, and define a deformation part 211 with the two side walls of the box 1 in the horizontal and vertical directions in the vertical direction. In the third part, four adjacent connecting parts 4122 in the vertical and horizontal directions can define a deformation part 211.

[0037] Furthermore, to facilitate the inflation and deflation of the first airbag 21 and adjust its elasticity, in one embodiment of this invention, each of the supporting plates 2 is provided with a first air hole 23 extending vertically, the first air hole 23 being connected to the first airbag 21. The housing 1 is provided with a second air hole 11 extending horizontally or vertically to one end, connecting to the accommodating cavity. The second air hole 11 is connected to the first air hole 23 via a connecting pipe 3, so that the first air hole 23, the connecting pipe 3, and the second air hole 11 together form an inflation airway. In this embodiment, through the design of the inflation airway, when it is necessary to inflate the first airbag 21, simply connect the inflation device to the second air hole 11 on the side of the housing 1, and gas can be injected into the first airbag 21 through the connecting pipe 3 and the first air hole 23, adjusting its elasticity to better adapt to the cushioning and protection needs of different products. Similarly, when deflation is required, the gas inside the first airbag 21 can be discharged sequentially through the inflation channel via the first air hole 23, the connecting pipe 3, and the second air hole 11, which is convenient and quick. This design not only improves the flexibility of the plastic turnover box 100 but also further enhances its protective effect on the product.

[0038] Furthermore, to prevent backflow of gas during inflation or deflation, which would affect the inflation effect, and to prevent gas leakage from the first air bladder 21 during use, in one embodiment of this invention, the plastic turnover box 100 further includes a one-way valve located within the inflation air passage. The one-way valve restricts the flow of gas from the first air hole 23 to the second air hole 11. This configuration ensures that gas can only flow in one direction, from the second air hole 11 to the first air hole 23, thereby guaranteeing smooth inflation and limiting the gas flow within the first air bladder 21. This ensures that the first air bladder 21 can always maintain its ability to limit and cushion the product.

[0039] Of course, it is understandable that when it is necessary to deflate, an external force can be applied to the one-way valve to drive the valve port to open, so that the gas in the first airbag 21 is discharged from the first airbag 21 through the first air hole 23, the connecting pipe 3 and the second air hole 11 in sequence under the pressure of the first airbag 21, so as to realize the deflation of the first airbag 21.

[0040] It should be noted that this utility model does not limit the specific location of the one-way valve. In one embodiment of this utility model, the one-way valve can be located at the first air hole 23; in the second embodiment of this utility model, the one-way valve can be located at the connecting pipe 3; and in the third embodiment of this utility model, the one-way valve can be located at the second air hole 11.

[0041] Specifically, in this embodiment, the one-way valve is located at the second air port 11 for ease of operation.

[0042] Furthermore, the design of the bearing position should be tailored to the characteristics of the product to ensure the stability of the product when placed on the bearing plate 2. For example, in one embodiment of this utility model, when the product is arranged in a ring shape, the upper surface of the bearing plate 2 is provided with a positioning post, which forms the bearing position.

[0043] In another embodiment of this utility model, a bearing groove 24 is recessed on the upper end surface of the bearing plate 2, and the bearing groove 24 forms the bearing position. With this configuration, the bearing groove 24 can be applied to various products and provides a certain degree of restraint for the products, preventing them from sliding or shifting during transport.

[0044] It should be further explained that the first airbag 21 can only buffer the external force above the product. In order to avoid the product being damaged by the force below, an elastic layer 25 is provided on the bottom and wall of the bearing groove 24. The elastic layer 25 is used to contact the product.

[0045] With this configuration, when the product is placed in the support groove 24, the elastic layer 25 can directly contact the product. When the product is subjected to an external force from below, the elastic layer 25 will undergo elastic deformation, effectively buffering the impact force from below and preventing damage to the product due to the force from below. Furthermore, the elastic layer 25 can also increase the friction between the product and the support groove 24, further preventing the product from sliding or shifting during transportation and improving the stability of the product placement.

[0046] Furthermore, the elastic layer 25 can reduce the wear of the bearing groove 24 on the product surface, thereby protecting the product surface from damage.

[0047] In actual use of the plastic turnover box 100, in order to facilitate the installation and disassembly of the support plate 2 and the box body 1, each support plate 2 is connected to the box body 1 through a connecting structure 4. The connecting structure 4 includes a connecting part 4122 and a mating part 42. One of the connecting part 4122 and the mating part 42 is provided on the support plate 2, and the other is provided on the inner side wall of the box body 1. The connecting part 4122 is movably arranged in the direction of approaching or away from the mating part 42. During the movement of the connecting part 4122, the connecting part 4122 has a connecting position that connects to the mating part 42, and a disassembly position that avoids the mating part 42. With this configuration, when the support plate 2 needs to be installed onto the housing 1, the connecting part 4122 is initially in the disassembly position. When the support plate 2 is placed in the accommodating cavity, the connecting part 4122 can move towards the corresponding mating part 42 to the connection position and engage with the corresponding mating part 42, thereby connecting the support plate 2 and the housing 1 to ensure the connection between them. When the support plate 2 needs to be removed from the housing 1, the connecting part 4122 is initially in the connection position. At this time, the connecting part 4122 needs to be moved away from the corresponding mating part 42 to move from the connection position to the disassembly position, thereby releasing the engagement with the mating part 42, allowing the support plate 2 and the housing 1 to move relative to each other, and then removing the support plate 2 from the housing 1.

[0048] It should be noted that this utility model does not limit the specific structural form of the connecting part 4122 and the mating part 42. In one embodiment of this utility model, the connecting part 4122 is configured as a pin and extends in the horizontal or vertical direction, and the mating part 42 is configured as a mating hole. When the connecting part 4122 is in the connecting position, the pin is inserted and mated with the mating hole. In another embodiment of this utility model, the connecting part 4122 is configured as a first abutting block, and the mating part 42 is configured as a second abutting block. When the connecting part 4122 is in the connecting position, the first abutting block and the second abutting block abut against each other at one end face facing upwards.

[0049] It should also be noted that, in this utility model, since the open end of the box 1 exposes the accommodating cavity, the product placed on the uppermost support plate 2 cannot contact the first airbag 21, thus being subject to the limiting and buffering effects of the first airbag 21. Therefore, to protect the product placed on the uppermost support plate 2, in one embodiment of this utility model, the plastic turnover box 100 further includes a cover 5, which is disposed on the open end of the box 1. The lower end of the cover 5 is provided with a second airbag 51, which is elastically configured. With this configuration, when the cover 5 is closed on the open end of the box 1, the second airbag 51 can contact the product placed on the uppermost support plate 2 and limit and buffer the product through its elastic deformation. Specifically, during the transfer process, if the product is subjected to vibration or impact from above, the second airbag 51 can undergo elastic deformation, effectively absorbing and dispersing external forces, thereby preventing the product from being damaged due to direct collision.

[0050] In addition, in order to enhance the overall strength of the plastic turnover box 100 and enable it to withstand heavier loads, in one embodiment of the present invention, the plastic turnover box 100 further includes a reinforcing structure 6, the reinforcing structure 6 including a plurality of reinforcing ribs, each of the reinforcing ribs extending in the vertical direction and spaced apart on the circumferential side of the box body 1.

[0051] This arrangement effectively strengthens the sidewalls of the box 1, preventing deformation or damage under heavy loads and thus improving the overall structural stability and durability of the plastic turnover box 100. Furthermore, the ribs are spaced apart circumferentially around the box 1, evenly distributing external forces and preventing localized stress concentration, further enhancing the load-bearing capacity of the box 1.

[0052] Meanwhile, the reinforcing ribs can also increase the rigidity of the box 1 to a certain extent, reducing vibration caused by shaking or collision during transportation, and providing a more stable storage environment for the products inside the box. In addition, this reinforcing structure 6 design does not significantly increase the weight of the plastic turnover box 100, maintaining its lightweight and easy-to-handle characteristics while ensuring strength.

[0053] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
