[0033] like Figures 1 to 6As shown, an embodiment of the utility model provides a building insulation wall panel, including a metal outer panel 1, a decorative inner panel 2, and a side sealing frame 3 arranged between the metal outer panel 1 and the decorative inner panel 2, the side sealing frame 3 is fixedly connected to the metal outer panel 1, a ventilation grid 5 is arranged inside the side sealing frame 3, and the gap between the ventilation grid 5 and the gap between the metal outer panel 1 and the decorative inner panel 2 is filled with a heat insulation core 4, the ventilation grid 5 includes a plurality of groups of connecting tubes 9 and connecting pipes 10, and the plurality of groups of connecting tubes 9 and connecting pipes 10 are mesh-connected and internally connected, wherein at least A closed structure 7 is provided in the two groups of connecting tubes 9. The closed structure 7 can close the port of the connecting tube 9. The port on one side of the connecting tube 9 close to the decorative inner panel 2 is in a closed state to prevent the insulation core from clogging the connecting tube. By setting up a ventilation grid 5, the metal outer panel 1 and the inside of the decorative inner panel 2 can exchange gas with the outside world. The air flow inside the ventilation grid 5 can take away the heat in the wall, thereby improving the heat dissipation effect of the wall, so that the indoor temperature will not be too high, reducing the temperature difference between indoor and outdoor, reducing the energy consumption of air conditioning in summer, and achieving energy-saving and environmental protection effects.

[0034] like Figure 2 and Figure 3 As shown, the side sealing baffle frame 3 is a square frame, the ventilation grid 5 is embedded in the side sealing baffle frame 3 and fixedly connected thereto, the heat insulation core 4 is filled in the gap of the ventilation grid 5 to wrap and fix the connecting tube 10, and the heat insulation core 4 is preferably foamed rubber. By setting the heat insulation core 4, when in use, the fluid foamed rubber is poured on the metal outer plate 1 and the decorative inner plate 2, waiting for it to foam and expand to fill the gap between the metal outer plate 1 and the decorative inner plate 2, wherein the expanded foamed rubber is filled in the gap of the ventilation grid 5 to wrap the outer wall of the connecting tube 10, and after the foamed rubber is formed into the heat insulation core 4, the heat insulation core 4 plays a certain fixing role on the ventilation grid 5, and the fixedly formed heat insulation core 4 has many small hole structures, and the air stored in these small holes can slow down the temperature transfer, thereby making The thermal insulation core 4 has a good thermal insulation effect. When the ventilation grid 5 is not ventilated, the thermal insulation core 4 can slow down the heat conduction between indoor and outdoor, and then slow down the influence of external high temperature on indoor temperature, thereby improving the indoor thermal insulation effect. When the ventilation grid 5 is ventilated, the gas flowing in the ventilation grid 5 can make the outside air and the air inside the ventilation grid 5 and the heat thereon quickly transfer. At the same time, the heat on the thermal insulation core 4 wrapped on the outside of the connecting pipe 10 can be directly transferred to the ventilation grid 5. The rapid thermal conductivity effect of the ventilation grid 5 can also help the thermal insulation core 4 to conduct heat quickly, thereby accelerating the heat transfer inside the wall. When the outside air temperature is low, the rapid thermal conductivity effect of the ventilation grid 5 and the thermal insulation core 4 can quickly dissipate heat to the wall, thereby achieving an accelerated indoor cooling effect.

[0035] The metal outer plate 1 is a U-shaped structure. The metal outer plate 1 and the decorative inner plate 2 are fixedly connected by welding and are in a square frame structure with openings at both ends. The side wall of the metal outer plate 1 is provided with ventilation holes 8. There are preferably two groups of ventilation holes 8, which are respectively opened at the two ends of the diagonal of the metal outer plate 1. The ventilation holes 8 are aligned with and connected to the corresponding connecting tubes 9. A closed structure 7 is installed in the connecting tubes 9 aligned with the ventilation holes 8. The two diagonally distributed groups of ventilation holes 8 serve as air inlets and exhaust ports, respectively. When the closed structure 7 is opened, the external airflow enters the connecting tube 9 through the air inlet through one group of the closed structures 7, and is spread to other connecting tubes 9 through the connecting pipe 10, and is finally discharged from another group of connecting tubes 9 installed with the closed structure 7. The exhausted airflow takes away the moisture in the wall, so that the wall remains dry.

[0036] like Figures 4 to 6 As shown, the closed structure 7 includes an outer sleeve 11 which is clamped with the inside of the connecting tube 9, an inner sleeve 12 is movably sleeved inside the outer sleeve 11, a filter cartridge 13 is installed inside the inner sleeve 12, and the outer diameter of the filter cartridge 13 is the same as the inner diameter of the inner sleeve 12. By setting the closed structure 7, when in use, the outer sleeve 11 is installed inside the connecting tube 9 to cover the port of the connecting tube 9, and the inner sleeve 12 is installed inside the outer sleeve 11 and can be switched between open and closed states by rotating relative to the outer sleeve 11. The filter cartridge 13 is installed inside the inner sleeve 12 to filter the airflow passing through the inner sleeve 12, and filter and remove dust particles and water vapor in the airflow, thereby ensuring that the airflow flowing through the ventilation grid 5 is dry and clean air, thereby avoiding dust and water accumulation inside the ventilation grid 5.

[0037] The outer diameter of the outer sleeve 11 is the same as the inner diameter of the connecting tube 9. Two groups of movable grooves 18 are symmetrically provided on the side wall of the outer sleeve 11. A positioning block 19 is fixedly connected to the side wall of the outer sleeve 11. The outer sleeve 11 is clamped with the connecting tube 9 through the positioning block 19. By setting the positioning block 19, the outer sleeve 11 can be installed in the connecting tube 9 and cannot rotate relative to the connecting tube 9, which facilitates the inner sleeve 12 to rotate relative to the outer sleeve 11. A top plate 14 is fixedly connected to the top of one end of the outer sleeve 11. The outer diameter of the top plate 14 is larger than the inner diameter of the connecting tube 9. A through hole 16 is provided at the center of the top of the top plate 14. A plurality of first vents 15 are evenly arranged outside the through hole 16. The first vents 15 are fan-shaped. Two groups of positioning grooves 17 are provided on the top of the top plate 14. The angle between the two groups of positioning grooves 17 is the same as the angle between two adjacent groups of first vents 15.

[0038] The outer diameter of the inner sleeve 12 is the same as the inner diameter of the outer sleeve 11. The inner sleeve 12 is a cylindrical structure with one end closed. A rotating handle 21 is fixedly connected to the center of the closed end face of the inner sleeve 12. A positioning pile 22 is fixedly connected to the inner side wall of the end of the rotating handle 21. By setting the rotating handle 21, it is convenient to drive the inner sleeve 12 to rotate. By setting the positioning pile 22, the positioning pile 22 is adapted to the positioning groove 17. By embedding the positioning pile 22 into the corresponding positioning groove 17, it is convenient to position and fix the inner sleeve 12, so that the inner sleeve 12 can be rotated and locked relative to the outer sleeve 11. A plurality of groups of second vents 20 are evenly arranged on the outer side of the rotating handle 21. The second vents 20 and the first vents 15 are structurally connected. And the number is the same. When the inner sleeve 12 is connected to the outer sleeve 11, the position of the second vent 20 is staggered with the position of the first vent 15, so that the top plate 14 and the top of the inner sleeve 12 are closed to each other, and the outer wall of the inner sleeve 12 is symmetrically provided with two groups of corrugated spring sheets 23, one end of the corrugated spring sheet 23 is fixedly connected to the inner sleeve 12, and the other end of the corrugated spring sheet 23 is a free end. The two groups of corrugated spring sheets 23 are symmetrically distributed with the central axis of the inner sleeve 12 as the center. When the inner sleeve 12 rotates, the two groups of corrugated spring sheets 23 will be squeezed at the same time to cause elastic deformation. When the external force of rotating the inner sleeve 12 disappears, the elastic force of the corrugated spring sheet 23 drives the inner sleeve 12 to return to its original position.

[0039] The working principle of the technical solution provided by the utility model is as follows: when manufacturing wall panels, firstly, the side sealing frame 3 is laid flat, and then the ventilation grid 5 is placed in the side sealing frame 3 and fixedly connected thereto, and then the side sealing frame 3 with the ventilation grid 5 installed is tightly attached to and fixed to the inner wall of the metal outer panel 1, and it is necessary to align the connecting tube 9 with the closing structure 7 installed with the vent 8 on the metal outer panel 1, and make sure that the closing structure 7 is in a closed state, and then fix the decorative inner panel 2 and the metal outer panel 1 to form a square frame, and finally, inject foam rubber into the square frame and wait for it to expand and take shape, and the formed foam rubber wraps the ventilation grid 5 and is fixed to the metal outer panel 1, the decorative inner panel 2 and the side sealing frame 3, and is called the heat insulation core 4.

[0040] When in use, bolts are used to assemble the wall panels to the color steel frame. Under normal conditions, the closed structure 7 is in a closed state, wherein the outer sleeve 11 is installed in the connecting tube 9, and the positioning block 19 is embedded in a groove in the connecting tube 9 that is adapted thereto, so that the outer sleeve 11 is clamped with the connecting tube 9, and the outer sleeve 11 cannot rotate in the connecting tube 9. When the inner sleeve 12 is installed in the outer sleeve 11, the corrugated spring piece 23 is embedded in the movable groove 18 and abuts against the side wall of the movable groove 18. At this time, the positioning pile 22 is embedded in a group of positioning grooves 17, and the inner sleeve 12 is clamped with the outer sleeve 11. The first vent 15 on the outer sleeve 11 and the second vent 20 on the inner sleeve 12 are staggered, so that the inside of the closed structure 7 cannot exchange gas with the outside world.

[0041] In hot weather, when no one lives indoors during the day, the closed structure 7 can be opened to allow the gas flow in the ventilation grid 5 to quickly exchange heat with the outside world to slow down the increase in indoor temperature. When opening the closed structure 7, just hold the rotating handle 21 and pull it outward to disengage the positioning pile 22 from the positioning groove 17, and at the same time rotate the positioning pile 22 to drive the inner sleeve 12 to overcome the resistance of the corrugated spring sheet 23 and rotate until the positioning pile 22 is aligned with the next set of positioning grooves 17 and embedded therein, and the inner sleeve 12 is locked again. At this time, the first vent 15 on the outer sleeve 11 coincides with the second vent 20 on the inner sleeve 12, and the closed structure is closed. 7 can exchange gas with the outside, so that the gas inside the ventilation grid 5 is in a circulating state, which accelerates the heat conduction of the wall and accelerates the indoor temperature reduction. When the outside air temperature drops at night, the indoor temperature can be quickly reduced. When people live in the room at night, the rotating handle 21 can be pulled to separate the positioning pile 22 from the positioning groove 17. Under the elastic force of the corrugated spring sheet 23, the inner sleeve 12 automatically resets to the state of closing the first vent 15. At this time, the gas inside the wall does not flow, the heat conduction of the wall slows down, which is convenient for indoor heat preservation. After turning on the air conditioner to adjust the indoor temperature, it is convenient to keep the indoor temperature unchanged, save energy consumption, and achieve energy-saving and environmental protection effects.

[0042] When the air circulates inside the ventilation grid 5, the outside air enters the ventilation grid 5 through a group of closed structures 7, and is discharged from another group of closed structures 7 through each connecting tube 9 in the ventilation grid 5. When the outside airflow passes through the closed structure 7, the filter core tube 13 inside the inner sleeve 12 filters out the water vapor and dust particles carried in the airflow, thereby avoiding dust and water accumulation inside the ventilation grid 5.

[0043] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
