Description

Technical Field

[0001] The utility model relates to the field of flat door structures, and specifically to an airtight flat door structure. Background Art

[0002] The airtight flat door structure is a door type specially designed for environments such as clean operating rooms and clean workshops that require stable pressure. Its core lies in providing excellent airtight performance to reduce air leakage and ensure precise control of indoor pressure. This door uses an airbag-type sealing strip to closely fit around the door leaf and the door frame, automatically adapting to minor deformations to prevent air from escaping at the joints. At the same time, a liftable silicone sealing strip installed under the door leaf automatically descends to closely fit the ground when the door is closed and rises automatically when the door is opened to reduce wear, ensuring that the sealing effect and the movement of the door leaf do not interfere with each other. These innovative settings not only improve the aesthetics but also significantly extend the service life of the sealing strip, effectively solving the problems of easy wear of traditional fixed sealing strips and sealing failure when the internal and external pressure differences are large, thus comprehensively improving the sealing performance and reliability of the airtight flat door structure.

[0003] However, there are still some problems with the existing airtight flat door structures. For example, if there are sundries on the ground that are not cleaned in time, when the sealing strip descends to fit the ground, these sundries may cause the sealing strip to deform, resulting in poor sealing, which in turn affects the indoor pressure stability and cleanliness. In addition, over time, the material of the sealing strip will gradually age, and its elasticity and sealing performance will also decline. This process may be gradual and not easily noticed immediately, but it will gradually accumulate during long-term use and eventually lead to sealing failure. This not only affects the airtightness of the door but may also have an adverse impact on the indoor environment. Optimize this sentence by reducing the use of modifiers.
