Description

TECHNICAL FIELD

[0001] The utility model relates to broken bridge aluminum alloy door technical field, especially in kind of broken bridge aluminum alloy thermal insulation door. BACKGROUND

[0002] In modern architecture, the door is not only the passageway connecting indoor and outdoor space, but also the key element affecting the overall performance of the building. As a high-quality door product, the broken bridge aluminum alloy thermal insulation door has been widely concerned and applied due to its excellent thermal insulation performance, good air and water tightness, excellent strength and stability, and aesthetic and durable characteristics. The core structure of the broken bridge aluminum alloy thermal insulation door lies in the broken bridge technology. Aluminum alloy has the advantages of light weight, high strength, corrosion resistance, etc. The broken bridge adds a thermal insulation strip in the middle of the aluminum alloy profile, which effectively prevents heat conduction by dividing the aluminum alloy profile into two parts.

[0003] The applicant found that a broken bridge thermal insulation aluminum alloy door was disclosed in Chinese patent with publication (announcement) number CN220081174U. The patent mainly includes a broken bridge outer frame and a door and window glass installed in the middle of the outer frame. The inside of the broken bridge outer frame is installed with a U-shaped filling groove. The utility model sets a sealing strip cover on the top of the broken bridge outer frame. The door and window glass can be taken out by opening the sealing strip cover, and the U-shaped thermal insulation strip inside the broken bridge outer frame can be taken out, which facilitates the replacement of new thermal insulation strips and enables the aluminum alloy door to continue the thermal insulation function. However, in the above-mentioned prior art, the sealing strip is installed by the sealing strip cover, which is relatively cumbersome. Moreover, when the door is closed and opened for a long time, the sealing strip cover is easily squeezed and rubbed, which leads to unstable installation. In addition, the thermal insulation strip is squeezed for a long time, which reduces its elastic recovery ability, and cannot play a good thermal insulation role. Therefore, we propose a broken bridge aluminum alloy thermal insulation door. UTILITY MODEL CONTENTS
