Description

Technical Field

[0001] This utility model relates to a continuously sealed transition rubber corner, belonging to the technical field of building doors and windows. Background Technology

[0002] Aluminum profile doors and windows are widely used in the building door and window industry due to their excellent sealing and heat insulation properties. Sealing strips play a crucial role in the sealing of aluminum profile doors and windows, leading to the development of increasingly sophisticated sealing strip structures. These structures not only improve sealing performance but also extend the lifespan of the sealing strips. However, for doors and windows, sealing strips are typically inserted horizontally and vertically into positioning grooves, requiring disconnection at corners. This creates blind spots in the sealing, reducing the sealing performance of the doors and windows. If the sealing strip is continuous at corners, its unevenness makes it prone to fatigue damage during repeated door and window operations, significantly reducing its lifespan. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a continuously sealing transition rubber corner, which is set at the corner of the door frame or mullion. It not only has a firm positioning, but also ensures that the horizontal sealing strip and the vertical sealing strip are effectively connected, thereby improving the overall sealing performance of the door and window.

[0004] To solve the above problems, the specific technical solution of this utility model is as follows: a continuously sealed transition rubber corner, the transition rubber corner is located at the right-angle inner cavity where the horizontal profile and the vertical profile meet; the main body of the transition rubber corner is approximately cuboid; a snap-fit ​​boss is provided at its bottom, the snap-fit ​​boss snaps into the positioning groove of the sealing strip of the horizontal profile; positioning protrusions are provided on the side end face and the top end face of the main body respectively, the positioning protrusions are inserted into the sealing strips at the corresponding positions; the sealing strips in the horizontal profile, the sealing strips in the vertical profile and the transition rubber corner form a continuous seal, and are pressed tightly and sealed with the movable profile frame.

[0005] The main body has several cavities, and a support arm is formed between each pair of adjacent cavities.

[0006] The upper surface of the main body is provided with at least one vertical baffle, which is located outside the vertical sealing strip.

[0007] The positioning protrusion on the upper surface of the main body is inserted into the sealing strip on the vertical profile, and the sealing end of the sealing strip on the vertical profile corresponds to the end face of the baffle on the same side.

[0008] The upper surface of the main body is provided with a movable tongue, which overlaps with the sealing end of the sealing strip connected in the same direction.

[0009] The bottom side edge of the main body is provided with a slot, which engages with a protrusion on the horizontal profile.

[0010] The adapter corner is made of EPDM rubber and molded in one piece.

[0011] The thermal insulation structure between the cover and the profile in this application adopts the above-described structure, which has the following advantages:

[0012] 1. The side and top surfaces of the transition rubber corner are respectively provided with positioning protrusions to realize the connection of the sealing strips located in the horizontal and vertical profiles, so that the rubber strips form a continuity;

[0013] 2. The main body is equipped with cavities and support arms, which gives the overall structure the ability to easily deform and recover from deformation, effectively ensuring the sealing effect;

[0014] 3. The baffle plate on the top surface not only serves to position the installation, but also further enhances the sealing effect at the joint;

[0015] 4. The addition of a movable tongue ensures a continuous seal between the surface of the hinged or side-pull profile and the sealing strip and movable tongue, thereby improving the overall sealing performance. Attached Figure Description

[0021] like Figures 1 to 5 As shown, a continuously sealed transition corner is located at the right-angled inner cavity where the horizontal profile 10 and the vertical profile 11 intersect. It is integrally molded from EPDM rubber, giving the transition corner good elastic recovery, weather resistance, and aging resistance. The main body 1 of the transition corner is approximately cuboid; its bottom has a snap-fit ​​boss 2, which snaps into the positioning groove of the sealing strip of the horizontal profile 10. To ensure sealing performance, the surface of the snap-fit ​​boss 2 is typically sealed with waterproof sealant to the positioning groove of the sealing strip of the horizontal profile 10. Positioning protrusions 3 are respectively provided on the side and top surfaces of the main body 1. The positioning protrusions 3 insert into the corresponding sealing strips 13. To ensure sealing performance at the insertion point, waterproof sealant is applied at the contact point between the positioning protrusions 3 and the sealing strips 13.

[0022] To improve the flexibility of the main body 1 and give it a certain degree of elasticity, several cavities 4 are provided on the main body 1, and a support arm 5 is formed between each two adjacent cavities 4, thereby ensuring the sealing performance of the transition rubber corner.

[0023] The upper surface of the main body 1 is provided with at least one vertical baffle 6, which is located outside the vertical sealing strip 13. The baffle 6 has the function of installation and positioning, and can be inserted into the limiting edge of the vertical profile 11. It also has the function of blocking the wind at the joint, thus improving the sealing performance.

[0024] The positioning protrusion 3 on the upper surface of the main body 1 is inserted into the sealing strip 13 on the vertical profile 11, and the sealing end of the sealing strip 13 on the vertical profile 11 corresponds to the same side end face of the baffle 6. A movable tongue 7 is provided along the outer edge of the upper surface of the main body 1, and the movable tongue 7 overlaps in shape with the sealing end of the sealing strip 13 connected in the same direction. The positions of the positioning protrusions 3 at the upper and side ends position the connected sealing strip 13; therefore, the positions of the sealing strip 13 and the movable tongue must simultaneously conform to the surface of the movable profile to ensure continuous sealing.

[0025] The bottom side edge of the main body 1 is provided with a slot 8, which engages with a protrusion on the horizontal profile 10. The slot 8 improves the positioning stability between the main body 1 and the horizontal profile 10.
