Description

Technical Field

[0001] This utility model relates to the field of foam box technology, and in particular to an adjustable-size foam box. Background Technology

[0002] Foamed plastic is a polymer material composed of numerous tiny gas pores uniformly dispersed within a solid plastic matrix. This material is lightweight, has good thermal insulation properties, effectively absorbs sound and dampens vibrations, and its dielectric properties are even superior to those of its base resin material, making it widely applicable. Given its excellent properties, the market demand for foamed plastic is considerable, and it is frequently processed into boxes for storing various items.

[0003] For example, an adjustable-size foam box with publication (announcement) number CN221189587U includes: a box body, a horizontal adjustment baffle and a height-increasing frame. The box body has a receiving cavity, and a first adjustment groove and a second adjustment groove are respectively provided on the two side walls of the receiving cavity. The first adjustment groove and the second adjustment groove are arranged opposite to each other. The two ends of the horizontal adjustment baffle are respectively movably disposed on the first adjustment groove and the second adjustment groove, and the first adjustment groove and the second adjustment groove are used to limit and fix the horizontal adjustment baffle.

[0004] In summary, the existing technology has the following technical problems: Although the existing technology can adjust the distance between the two horizontal adjustment baffles during use, the distance adjustment is limited by the distance between the two adjustment slots, so the adjustment range is limited and it is not conducive to adapting to more sizes of touch glass products. Therefore, we propose an adjustable size foam box. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Example

[0020] Reference Figure 1-4An adjustable-size foam box includes a foam box body 1 and a lid 2 mounted on the top of the foam box body 1. Two support plates 3 are mounted inside the foam box body 1, and a size adjustment mechanism is installed between the two support plates 3. The size adjustment mechanism is used to adjust the distance between the two support plates 3. The size adjustment mechanism includes a support groove 4, a first toothed protrusion 5, and a second toothed protrusion 6. The top and bottom ends of both ends of the support plates 3 are integrally provided with the first toothed protrusion 5. Two rows of second toothed protrusions 6 are fixed on both sides inside the foam box body 1. The first toothed protrusions 5 and the second toothed protrusions 6 are engaged and connected. During use, both ends of the touch-sensing glass are inserted into the support groove 4 and supported by the support plates 3. After the touch-sensing glass is fully placed, the two support plates 3 are placed inside the foam box body 1. It is understood that the distance between two adjacent second toothed protrusions 6 is fixed, and can be designed according to the progressive size specifications of the touch-sensing glass in actual production.

[0021] A size limiting mechanism is installed between the foam box 1 and the support plate 3. The size limiting mechanism includes a storage groove 7, a limiting strip 8, and an arc block 10. The foam box 1 has storage grooves 7 at both ends on its inner side. The bottom of the inner side of the storage groove 7 is rotatably connected to the limiting strip 8. The limiting strip 8 is fitted with the inner side of the storage groove 7. Multiple arc blocks 10 are evenly distributed and fixed on the side of the two support plates 3 that are far apart from each other. The arc blocks 10 are all connected to one end of the limiting strip 8. In actual use, the two ends of the touch sensor glass are inserted into the support groove 4. Through the setting of the limiting strip 8, the support plate 3 can be supported and limited, and a part of the force can be borne.

[0022] The top of the limiting strip 8 is integrally fixed with a connecting cylinder 9, and the inner side of the arc block 10 is provided with a mating interface 11. The mating interface 11 is fitted with the connecting cylinder 9. During the connection process, when the bearing plate 3 is inserted into the foam box 1, the limiting strip 8 can be rotated so that the connecting cylinder 9 can be well connected with the mating interface 11 in the corresponding arc block 10.

[0023] Multiple slots 12 corresponding to the positions of the arc-shaped blocks 10 are evenly distributed on one side of the limiting strip 8. The slots 12 are all slidably connected to the arc-shaped blocks 10. When the arc-shaped blocks 10 on the support plate 3 are inserted into the corresponding slots 12, the distance between the two support plates 3 is at its maximum. Example

[0024] Further optimizations to Example 1, specifically, such as... Figure 1-2As shown, a rectangular strip 13 is fixed to the top of the foam box 1, and a rectangular frame groove 17 corresponding to the position of the rectangular strip 13 is opened on the inner side of the box cover 2. The rectangular frame groove 17 is slidably connected to the rectangular strip 13. The top of the rectangular strip 13 is equipped with a height adjustment mechanism, which includes a height-adjusting strip 14, a post 15, and a socket 16. The height-adjusting strip 14 is fitted to the top of the rectangular strip 13 and is in close contact with the rectangular strip 13. The height-adjusting strip 14 is slidably connected to the rectangular frame groove 17. The four corners at the bottom of the height-adjusting strip 14 are all fixed with posts 15. The four corners at the top of the rectangular strip 13 and the height-adjusting strip 14 are all provided with sockets 16. The sockets 16 and posts 15 are fitted together. When it is necessary to raise the height of the box cover 2, the distance between the foam box 1 and the box cover 2 is adjusted, and the posts 15 on the height-adjusting strip 14 are inserted into the sockets 16 on the rectangular strip 13 to complete the raising process. Multiple height-adjusting strips 14 can be used to raise the height of the box cover 2.

[0025] In summary: This utility model addresses the technical problem that, while existing technologies can adjust the distance between two lateral adjustment baffles during use, this adjustment is limited by the distance between the two adjustment slots, thus restricting the adjustment range and making it unsuitable for adapting to a wider range of tactile glass products. The present invention employs the technical solutions described in the above embodiments. Furthermore, the implementation process of the above technical solutions is as follows: When it is necessary to adjust the distance between the two support plates 3, lift the support plate 3 upwards so that the first tooth protrusion 5 on the support plate 3 separates from the second tooth protrusion 6 inside the foam box 1. Then insert the support plate 3 into the corresponding position so that the first tooth protrusion 5 and the second tooth protrusion 6 re-engage and connect. During this process, rotate the limiting strip 8 so that the limiting strip 8 drives the connecting cylinder 9. Then, place the connecting cylinder 9 against the corresponding arc block 10 and connect it with the interface 11. Since the foam material has a certain deformation capability, this process can be easily achieved, and the size adjustment process can be completed.

[0026] With the above-mentioned settings, this application will certainly solve the above-mentioned technical problems, and at the same time achieve the following technical effects: 1. Through the structural design of the size adjustment mechanism and the size limiting mechanism, this utility model makes it easy to adjust the distance between the two bearing plates 3 in multiple stages. It can also provide auxiliary support and limit the bearing plates 3 through the limiting strip 8 and the connecting cylinder 9, thereby realizing flexible size adjustment and improving the flexibility of this device.

[0027] 2. Through the structural design of the height adjustment mechanism, this utility model allows the device to adjust the distance between the box cover 2 and the foam box 1, which facilitates the filling of cushioning material between the product and the box cover 2, thereby improving the safety of freight transportation.
