Description

Technical Field

[0001] This utility model relates to the field of insulation board technology, and in particular to an insulation board structure of a vacuum insulation board composite aluminum honeycomb board. Background Technology

[0002] Insulation panels in cold storage primarily serve to provide insulation, heat insulation, moisture protection, corrosion prevention, and flame retardancy. They effectively reduce heat transfer between the inside and outside of the cold storage, lower energy consumption, and maintain a constant internal temperature, ensuring the quality and safety of stored goods.

[0003] Traditional composite insulation panels are assembled by simply using adhesive to connect vacuum insulation panels and aluminum honeycomb panels. Over time, these adhesive-bonded composite panels experience a decrease in strength due to various external forces. Therefore, there is an urgent need for a composite insulation panel structure with high splicing strength. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a thermal insulation board structure for a vacuum insulation board composite aluminum honeycomb panel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A thermal insulation board structure for a vacuum insulation board composite aluminum honeycomb panel includes an upper aluminum honeycomb panel, a vacuum insulation panel, and a lower aluminum honeycomb panel. The upper aluminum honeycomb panel, the vacuum insulation panel, and the lower aluminum honeycomb panel are sequentially glued and stacked together, and a polyurethane filling block is provided on the outer side of the vacuum insulation panel. Multiple cavities are opened through the upper aluminum honeycomb panel, and each cavity has a downwardly fixed mounting post. Multiple limiting posts are movably arranged on each mounting post. The lower aluminum honeycomb panel and the polyurethane filling block are adapted to have mounting cavities corresponding to the mounting posts, and the corresponding limiting posts in the mounting cavities are adapted to have limiting cavities.

[0007] In addition, a preferred structure is that polyurethane filling blocks are glued and installed on all four sides of the vacuum insulation panel, and multiple eccentric hook components are provided in each polyurethane filling block.

[0008] In addition, a preferred structure is that each of the mounting columns has an internal movable cavity and a knob groove on its top.

[0009] In addition, in a preferred configuration, each of the knob slots is vertically inserted with a screw that rotates downwards, and the other end of each screw extends into the movable cavity and is fixedly connected to the pressure column.

[0010] In addition, a preferred structure is that multiple side cavities are provided outward on the side walls of the active cavity, and a fixing column is vertically fixed in each side cavity.

[0011] In addition, in a preferred structure, all the limiting posts are located within the side cavity and are movable. Each limiting post is adapted to have a vertical fixing post cavity corresponding to the fixing post, and the end of the limiting post facing the pressing post is provided with an inclined surface.

[0012] The beneficial effects of this utility model are as follows: the upper aluminum honeycomb panel, the vacuum insulation panel, the lower aluminum honeycomb panel, and the polyurethane filling block are glued and spliced ​​together. By inserting the mounting post into the mounting cavity and cooperating with the mutual locking between the limiting post and the limiting cavity, the lower aluminum honeycomb panel and the polyurethane filling block can be fixed on the upper aluminum honeycomb panel, thereby further enhancing the composite splicing strength between the upper aluminum honeycomb panel, the vacuum insulation panel, the lower aluminum honeycomb panel, and the polyurethane filling block.

Detailed Implementation

[0021] 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.

[0022] Reference Figure 1-7 A thermal insulation board structure for a vacuum insulation composite aluminum honeycomb panel includes an upper aluminum honeycomb panel 1, a vacuum insulation panel 2, and a lower aluminum honeycomb panel 3. The upper aluminum honeycomb panel 1, the vacuum insulation panel 2, and the lower aluminum honeycomb panel 3 are sequentially glued and stacked together, and a polyurethane filling block 4 is provided on the outer side of the vacuum insulation panel 2. Multiple cavities are formed through the upper aluminum honeycomb panel 1, and each cavity has a downwardly fixed mounting post 5. Multiple limiting posts 55 are movably provided on each mounting post 5. The lower aluminum honeycomb panel 3 and the polyurethane filling block 4 are each adapted to have mounting cavities 6 corresponding to the mounting posts 5, and each mounting cavity 6 is adapted to have a limiting cavity 61 corresponding to the limiting posts 55.

[0023] The vacuum insulation panel 2 has polyurethane filler blocks 4 glued and installed on all four sides, and each polyurethane filler block 4 contains multiple eccentric hook assemblies 41. The polyurethane filler blocks 4 improve the thermal insulation performance of the sides of the vacuum insulation panel 2, and the eccentric hook assemblies 41 allow this composite panel to be spliced ​​with other composite panels. It is worth noting that the specific structure and operation of the eccentric hook assembly 41 are existing technologies and will not be described in detail here.

[0024] Each mounting post 5 has an internal movable cavity 52, and each mounting post 5 has a knob groove 51 on its top. A screw 54 is vertically inserted into each knob groove 51, with the other end of the screw 54 extending into the movable cavity 52 and fixedly connected to the pressure post 541. A knob is fixedly mounted on the top of the screw 54 for the user to rotate.

[0025] The movable cavity 52 has multiple outwardly opening side cavities 53 on its side walls, and each side cavity 53 has a vertically fixed post 531. Limiting posts 55 are all movable within the side cavities 53, and each limiting post 55 has a vertically opening fixed post cavity 551 corresponding to the fixed post 531. The end of the limiting post 55 facing the pressing post 541 has an inclined surface. The fitting arrangement between the fixed post 531 and the fixed post cavity 551 prevents the limiting post 55 from falling out of the side cavity 53.

[0026] In this embodiment, the upper aluminum honeycomb panel 1, the vacuum insulation panel 2, the lower aluminum honeycomb panel 3, and the polyurethane filler block 4 are spliced ​​together by adhesive bonding. The addition of the mounting column 5 in this application can further improve the stability of the upper aluminum honeycomb panel 1, the lower aluminum honeycomb panel 3, and the polyurethane filler block 4 during splicing, and enable the upper aluminum honeycomb panel 1 and the lower aluminum honeycomb panel 3 to stably clamp the vacuum insulation panel 2, thereby improving its splicing strength.

[0027] Furthermore, when the user needs to splice them together, simply apply glue evenly to the joint, then stack them together, ensuring that the mounting posts 5 on the upper aluminum honeycomb panel 1 are properly inserted into the mounting cavities 6 within the lower aluminum honeycomb panel 3 and the polyurethane filler block 4. This allows for positioning during splicing, and at this time, the limiting cavities 61 within the mounting cavities 61 are all aligned and adapted to the side cavities 53 on the mounting posts 5.

[0028] The user then simply rotates the screw 54 using the knob, causing it to rotate downwards and move the pressure column 541 downwards synchronously. Since one end of the limiting column 55 is inclined, all the limiting columns 55 are pushed outwards as the pressure column 541 moves downwards. This pushes the limiting columns 55 from the side cavity 53 into the limiting cavity 61, further securing the vacuum insulation panel 2 and the lower aluminum honeycomb panel 3 through the interlocking action between the limiting columns 55 and the limiting cavity 61, thereby improving the splicing strength between the upper aluminum honeycomb panel 1, the lower aluminum honeycomb panel 3, and the polyurethane filling block 4. Furthermore, the clamping of the vacuum insulation panel 2 by the upper and lower aluminum honeycomb panels 1 and 3 also enhances the splicing strength of the vacuum insulation panel 2.

[0029] Furthermore, when the screw 54 is fully rotated into the movable cavity 52, the knob adapter is located in the knob slot 51.

[0030] Furthermore, the mounting column 5 and mounting cavity 6 in this application can be customized according to the actual size of the plate, as long as they can be adapted for splicing.

[0031] It is worth noting that the specific bonding methods described in this application are all existing technologies, so they will not be elaborated upon further.

[0032] In this embodiment, the upper aluminum honeycomb panel 1, the vacuum insulation panel 2, the lower aluminum honeycomb panel 3, and the polyurethane filling block 4 are glued together. By inserting the mounting post 5 into the mounting cavity 6 and cooperating with the mutual locking between the limiting post 55 and the limiting cavity 61, the lower aluminum honeycomb panel 3 and the polyurethane filling block 4 can be fixed on the upper aluminum honeycomb panel 1, thereby further enhancing the composite splicing strength between the upper aluminum honeycomb panel 1, the vacuum insulation panel 2, the lower aluminum honeycomb panel 3, and the polyurethane filling block 4.

[0033] 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.
