Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy plate technology, specifically to a heat-insulating aluminum alloy plate. Background Technology

[0002] Aluminum alloy sheet is a metal sheet made of aluminum as the base material, with a certain proportion of alloying elements added, and then processed through rolling, extrusion and other processes. It has the characteristics of low density, high strength, strong corrosion resistance and excellent processing performance. It is widely used in construction, aerospace, automobile manufacturing, electronics and electrical appliances and packaging. Aluminum alloy sheet is not only beautiful in appearance, but also has good electrical and thermal conductivity. At the same time, its weather resistance and decorative properties can be further enhanced through surface treatment. It is a high-quality material that combines performance and economy.

[0003] Vacuum aluminum alloy profiles, as a new type of building material, have been initially adopted in some specific building projects and industrial applications due to their unique structural design and efficient heat insulation performance. This material significantly reduces heat transfer by forming a vacuum cavity inside the aluminum alloy profile, thus performing excellently in heat insulation. Although its application scope is relatively small at present, with the continuous maturation of technology and the reduction of costs, its application prospects in the field of building energy conservation are very broad in the future.

[0004] Under current technological conditions, vacuuming the interior of aluminum alloy panels often requires the assistance of external vacuum pumping equipment. If an aluminum alloy panel is damaged during use and needs to be replaced, the new panel must be vacuumed again. This undoubtedly requires maintenance personnel to carry and use vacuum pumping equipment. Carrying and using this equipment not only increases the complexity of maintenance work but also significantly increases the labor intensity of maintenance personnel. Especially in construction sites or environments with limited space, the difficulty of moving and operating the equipment will be further increased, causing many inconveniences to maintenance work. Therefore, to address the above problems, a thermal insulation aluminum alloy panel is proposed. Utility Model Content

[0030] Please see Figure 1-8 This utility model provides a technical solution:

[0031] A heat-insulating aluminum alloy plate includes an outer frame assembly 1, a first aluminum alloy plate 2, and a second aluminum alloy plate 3. An air storage assembly 4 is fixedly connected to the inner side of the outer frame assembly 1, and an exhaust assembly 5 is installed inside the air storage assembly 4. The air storage assembly 4 includes a cylindrical shell 41, with a connecting port 42 and an air storage groove 44 on the inner side of the cylindrical shell 41. A first silicone duckbill valve 43 is fixedly connected to the inner side of the connecting port 42. A horizontal plate 45 is fixedly connected to the inner side of the air storage groove 44, and a screw 46 is fixedly connected to the front end of the horizontal plate 45. The exhaust assembly 5 includes a movable cylinder 51, with an anti-detachment block 52 fixedly connected to the rear end of the movable cylinder 51. A rubber sealing ring 53 is fixedly connected to the outer side of the anti-detachment block 52. A through channel 54 is opened inside the movable cylinder 51, and a second silicone duckbill valve 55 and a circular block 57 are fixedly connected inside the through channel 54. A screw hole 58 and a flow port 59 are opened inside the circular block 57, and the inner side of the screw hole 58 is spirally connected to the outer side of the screw 46.

[0032] As a further implementation of this solution, the outer frame assembly 1 includes an outer frame body 11. The inner side of the outer frame body 11 is provided with a fixing groove 12, a vacuum groove 13 and an air passage groove 14. The vacuum groove 13 is connected to the air passage groove 14. Through the above settings, an internal channel is provided for the vacuuming operation, ensuring that air can flow smoothly and be extracted, thereby achieving a highly efficient vacuuming effect.

[0033] As a further implementation of this solution, the air passage 14 penetrates the front end of the outer frame body 11, the inner side of the front end of the air passage 14 is in contact with the outer side of the rubber sealing plug 15, and the rear end of the rubber sealing plug 15 is in contact with the front end of the movable cylinder 51. Through the above settings, the design of the air passage 14 facilitates the entry of gas inside the vacuum tank 13 into the air passage 14, and the design of the rubber sealing plug 15 serves to seal the air passage 14 and improve the aesthetics.

[0034] As a further implementation of this solution, the inner side of the front fixing groove 12 is fixed to the inner side of the first aluminum alloy plate 2, and the inner side of the rear fixing groove 12 is fixedly connected to the outer side of the second aluminum alloy plate 3. The air passage groove 14 is set between the first aluminum alloy plate 2 and the second aluminum alloy plate 3. The outer sides of the first aluminum alloy plate 2 and the second aluminum alloy plate 3 are both sealed to the inner side of the outer frame body 11 with sealant. Through the above settings, the sealing of the aluminum alloy plate is ensured, preventing air from seeping in from the outside during the vacuuming process and improving the stability of the vacuuming effect.

[0035] As a further implementation of this solution, the outer side of the shell 41 is fixedly connected to the inner side of the air passage 14, and a gap is provided between the rear end of the shell 41 and the rear end of the vacuum groove 13. The connecting port 42 is connected to the gas storage groove 44, the gas storage groove 44 penetrates the front end of the shell 41, and the connecting port 42 penetrates the rear end of the shell 41. The center of the screw 46 and the center of the connecting port 42 are on the same horizontal line. Through the above settings, a clear path is provided for the flow of air during the vacuuming process, ensuring that air can smoothly enter the gas storage groove 44 from the vacuum groove 13, thereby improving the vacuuming efficiency.

[0036] As a further implementation of this solution, the through channel 54 penetrates the inner side of the moving cylinder 51, and the flow port 59 penetrates the inner side of the annular block 57. The flow port 59 is connected to the through channel 54. An operating handle 56 is fixedly connected to the front end of the moving cylinder 51. Through the above-mentioned design, the connection between the through channel 54 and the flow port 59 allows air to enter the through channel 54 through the flow port 59 and be discharged during the vacuuming process, thus achieving effective discharge of internal gas. At the same time, the setting of the operating handle 56 provides convenience for manual operation.

[0037] As a further implementation of this solution, the movable cylinder 51 is embedded in the inner side of the gas storage groove 44, the outer side of the rubber sealing ring 53 is in contact with the inner side of the gas storage groove 44, and the structure of the second silicone duckbill valve 55 is the same as that of the first silicone duckbill valve 43. Through the above settings, the device can maintain good sealing performance at different stages, which improves the reliability and efficiency of vacuuming operation.

[0038] Workflow: When evacuating the vacuum tank 13, the operating handle 56 is rotated via the front end of the air passage 14, causing the moving cylinder 51 and the annular block 57 to rotate. As the annular block 57 rotates, the screw hole 58 is spirally connected to the outer side of the screw 46, causing the annular block 57 to move the rubber sealing ring 53 and the moving cylinder 51 forward. Because the rubber sealing ring 53 seals between the anti-detachment block 52 and the cylinder shell 41, the second silicone duckbill valve 55 is tightly closed as the rubber sealing ring 53 and the moving cylinder 51 move forward. This creates a negative pressure inside the air storage groove 44. Under this negative pressure, the air between the first aluminum alloy plate 2 and the second aluminum alloy plate 3 enters the air passage 14 through the vacuum tank 13, then enters the first silicone duckbill valve 43 through the air passage 14, and finally enters the air storage through the first silicone duckbill valve 43 and the connecting port 42. Inside the groove 44, after the gas storage groove 44 is filled with gas, the operating handle 56 is turned in the opposite direction. At this time, the exhaust assembly 5 moves backward as a whole. Through the exhaust assembly 5, the gas inside the gas storage groove 44 is squeezed. At this time, the gas inside the gas storage groove 44 will enter the through channel 54 through the flow port 59 and then be discharged through the second silicone duckbill valve 55. At this time, the opening of the first silicone duckbill valve 43 is in a closed state. This cycle is repeated to achieve the effect of vacuuming the vacuum groove 13 inside the first aluminum alloy plate 2 and the second aluminum alloy plate 3. Then, the rubber sealing plug 15 is used to seal the front end of the air passage groove 14 to improve the aesthetics. This vacuuming method does not require the use of vacuum pumping equipment, which is particularly suitable for later maintenance operations. It significantly reduces the labor intensity of maintenance personnel and reduces the difficulty of operation in a confined environment.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
