Description

Technical Field

[0001] This utility model relates to a corner cantilevered three-seal side-pressure sliding door, belonging to the technical field of building doors and windows. Background Technology

[0002] Sliding doors are suitable for use as partitions in compact spaces due to their small footprint and smooth movement. Existing sliding doors typically use weatherstripping for sealing, but weatherstripping has poor sealing performance and is prone to wear, making it unsuitable for use as a partition between indoor and outdoor spaces.

[0003] Existing triple seals are mostly used in hinged structures. However, if a triple seal structure is set in a sliding door, the installation position of the rubber strip often increases the frictional resistance between the door leaf and the door frame. Not only does it require more effort to pull when starting to push or pull, but the greater resistance during the entire sliding process also makes the sliding uneven and difficult to operate, thus affecting the user experience. In addition, the structural design is relatively complex, increasing the manufacturing difficulty and raising the overall product cost. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a corner cantilever type three-seal side-pressure sliding door. This three-seal structure can not only be smoothly applied to the sliding door structure, but is also easy to process and has a good sealing effect.

[0005] To solve the above problems, the specific technical solution of this utility model is as follows: A corner cantilever type three-seal side-pressure sliding door includes a door leaf and a door frame with side-pressure function and thermal break structure. The inner frame of the door leaf is provided with a first rubber strip groove, and an inner rubber strip is provided in the first rubber strip groove. The outer frame of the door leaf is provided with an inward corner cantilever. The inner frame of the door frame is provided with a stop frame, and the inner rubber strip is pressed and sealed with the inner frame of the door frame. A middle rubber strip is connected to the middle of the door frame through a second rubber strip groove, and the middle rubber strip overlaps on the corner cantilever. The outer frame of the door frame is provided with a third rubber strip groove, and an outer rubber strip is provided in the third rubber strip groove. The outer rubber strip is sealed and pressed against the outer frame of the door leaf.

[0006] The inner and outer rubber strips are made of foamed sealing strips.

[0007] The intermediate rubber strip is made of EPDM rubber.

[0008] The angled cantilever and the corresponding position of the door frame form a sealed space through the middle rubber strip and the outer rubber strip.

[0009] The surface of the door frame is provided with a cover profile, and an extension arm is provided on the cover profile. The third rubber strip groove is located at the end of the extension arm.

[0010] The angled cantilevered triple-seal side-pressure sliding door of this application adopts the above structure and has the following advantages:

[0011] 1. It can realize a three-seal structure for side-pressure sliding doors, improving the overall sealing performance;

[0012] 2. The inner and outer rubber strips are made of foamed sealing strips, which can effectively solve the problem of excessive closing pressure and keep the pressure within a comfortable range;

[0013] 3. The middle and outer rubber strips form a sealed space with the outer peripheral structure, further improving the overall airtightness of the door;

[0014] 4. The third rubber strip groove is located on the cover profile, which not only simplifies the door frame structure, but also improves the overall aesthetic performance of the door frame. Attached Figure Description

[0016] Figure 2 for Figure 1 AA sectional view. Detailed Implementation

[0017] like Figure 1 and Figure 2 As shown, a corner cantilever type three-sealed side-pressure sliding door includes a door leaf 1 with side-pressure function and a thermal break structure and a door frame 2. The inner frame of the door leaf 1 is provided with a first rubber strip groove 3, and an inner rubber strip 11 is provided in the first rubber strip groove 3. The outer frame of the door leaf 1 is provided with an inward corner cantilever 4. The inner frame of the door frame 2 is provided with a stop frame 6, and the inner rubber strip 11 is pressed and sealed with the inner frame of the door frame 2. A middle rubber strip 12 is connected to the middle of the door frame 2 through a second rubber strip groove 8, and the middle rubber strip 12 overlaps the corner cantilever 4. The outer frame of the door frame 2 is provided with a third rubber strip groove 7, and an outer rubber strip 13 is provided in the third rubber strip groove 7. The outer rubber strip 13 is sealed and pressed onto the outer frame of the door leaf 1.

[0018] The inner rubber strip 11 and the outer rubber strip 13 are made of foamed sealing strips. The middle rubber strip 12 is made of EPDM rubber.

[0019] The angled cantilever 4 and the door frame 2 are connected by a central rubber strip 12 and an outer rubber strip 13 to form a sealed space 5. This further improves the overall sealing performance of the door and reduces heat conduction. Simultaneously, this structure, when applied to the threshold, can improve the door's watertightness.

[0020] The surface of the door frame 2 is provided with a cover profile 10, and an extension arm is provided on the cover profile 10. The third rubber strip groove 7 is located at the end of the extension arm. The door frame 2 and the cover profile 10 are made into separate structures and processed separately, thereby reducing processing costs.
