[0034] The utility model provides an airtight component for the corner of a door or window. Compared with the prior art, the inner covering part 120 of the corner component 100 and the frame surface joint part 110 are perpendicular to each other, and the wall surface joint part 210 and the outer covering part 220 of the patch component 200 are also perpendicular to each other. When using the corner component 100 and the patch component 200, firstly, the frame surface joint part 110 of the corner component 100 is bonded to the two outer side surfaces of the window corner of the inner frame 400, and at this time, the inner covering part 120 is attached to the inner side of the end surface at the window corner joint and bonded and fixed. Then, the wall surface joint part 210 of the patch component 200 is bonded to the two inner side surfaces of the wall corner 600, and at this time, the outer covering part 220 is attached to the outer side of the end surface at the window corner joint and bonded and fixed.

[0035] See also Figure 2 The frame surface combination part 110 includes a first frame surface combination body 111 and a second frame surface combination body 112. The first frame surface combination body 111 and the second frame surface combination body 112 are vertically arranged. The frame surface combination part 110 is an L-shaped airtight film as a whole. The inner side surface of the first frame surface combination body 111 and the inner side surface of the second frame surface combination body 112 are respectively bonded to two adjacent outer side surfaces of the window corners of the inner frame body 400.

[0036] Specifically, the length of the first frame surface combination 111 is the same as the length of the second frame surface combination 112, and the width of the first frame surface combination 111 is the same as the width of the second frame surface combination 112, thereby maintaining consistent bonding strength between the two inner sides of the corner component 100 and the window corner inner frame 400, thereby avoiding sealing failure due to insufficient bonding strength on either side.

[0037] See also Figure 2 The inner covering part 120 includes a first inner covering body 121 and a second inner covering body 122. The first inner covering body 121 and the second inner covering body 122 are located in the same plane. The inner covering part 120 is an airtight film of an L-shaped structure as a whole, and is made integrally with the frame surface joint part 110. When the inner side surface of the first frame surface joint body 111 and the inner side surface of the second frame surface joint body 112 are respectively bonded to the two adjacent outer side surfaces of the inner frame body 400 at the window corner, the inner covering part 120 extends horizontally toward the outer side of the window corner. At this time, the corner of the inner frame body 400 bonded with the corner-pulling component 100 is aligned with the corner of the window corner joint and installed. The first inner covering body 121 and the second inner covering body 122 are attached to the inner side of the end surface at the window corner joint and bonded.

[0038] Specifically, the length of the first inner cover 121 is the same as the length of the second inner cover 122, and the width of the first inner cover 121 is the same as the width of the second inner cover 122, so as to maintain the inner side of the end surface of the corner joint between the corner member 100 and the window, and avoid the sealing failure caused by insufficient bonding strength on either side. In addition, the width of the first inner cover 121 and the width of the second inner cover 122 are not less than 1 / 2 of the width of the end surface at the corner joint, ensuring the effective area of ​​the inner side of the end surface at the corner joint covered by the corner member 100.

[0039] See also Figure 3 The wall joint part 210 includes a first wall joint body 211 and a second wall joint body 212. The first wall joint body 211 and the second wall joint body 212 are vertically arranged. The wall joint part 210 as a whole is an L-shaped airtight membrane. The outer side surface of the first wall joint body 211 and the outer side surface of the second wall joint body 212 are respectively bonded to two adjacent inner side surfaces of the wall corner 600.

[0040] Specifically, the length of the first wall combination 211 is the same as the length of the second wall combination 212, and the width of the first wall combination 211 is the same as the width of the second wall combination 212, thereby maintaining the bonding strength between the adjacent inner side surfaces of the patch component 200 and the wall corner 600 consistent, avoiding the occurrence of sealing failure due to insufficient bonding strength on either side.

[0041] See also Figure 3 The outer covering part 220 includes a first outer covering body 221 and a second outer covering body 222. The first outer covering body 221 and the second outer covering body 222 are located in the same plane. The outer covering part 220 is an L-shaped airtight film as a whole, and is made integrally with the wall joint part 210. When the inner side surface of the first wall joint body 211 and the inner side surface of the second wall joint body 212 are respectively bonded to the two adjacent inner side surfaces of the wall corner 600, the outer covering part 220 extends horizontally toward the inner side of the window corner. At this time, the first outer covering body 221 and the second outer covering body 222 are attached to the outer side of the end surface at the window corner joint and bonded;

[0042] At the same time, the inner side of the first outer cover 221 and the inner side of the second outer cover 222 are respectively overlapped with the outer side of the inner first inner cover 121 and the outer side of the second inner cover 122 to form an overlapped sealing area 300. The inner side of the first outer cover 221 is bonded to the outer side of the inner first inner cover 121, and the inner side of the second outer cover 222 is bonded to the outer side of the inner second inner cover 122. While ensuring that the outer cover 220 and the inner cover 120 overlap each other, the overlapped sealing area 300 is also bonded to improve the sealing strength of the joint area between the two.

[0043] Specifically, the length of the first outer cover 221 is the same as the length of the second outer cover 222, and the width of the first outer cover 221 is the same as the width of the second outer cover 222, so as to maintain the same bonding strength between the patch component 200 and the outer side of the end surface at the window corner joint, and avoid the sealing failure caused by insufficient bonding strength on either side. The width of the first outer cover 221 and the width of the second outer cover 222 are both greater than 1 / 2 of the width of the end surface at the window corner joint, while ensuring the effective bonding width of the first outer cover 221 and the first inner cover 121, and ensuring that the first outer cover 221 and the first inner cover 121 can form the above-mentioned overlapping sealing area 300 on the end surface at the window corner joint.

[0044] See also Figure 5 The corner-pulling component 100 and the patch component 200 both include a release paper layer 1, a bonding adhesive layer 2 and a base fabric layer 3 which are sequentially arranged. The release paper layer 1 can be peeled off from the bonding adhesive layer 2 to form a corresponding bonding surface. The corner-pulling component 100 and the patch component 200 are both composed of the above structure. The corner-pulling component 100 and the patch component 200 can use the above bonding surfaces to achieve corresponding bonding cooperation. The release paper layer 1 can be torn off and the direct pasting operation is convenient.

[0045] In addition, the corner-pulling component 100 and the patch component 200 can also be composed of a single base fabric layer 3. When the corner-pulling component 100 and the patch component 200 need to be bonded to the inner frame 400 and the wall corner 600, the pasting operation can be performed by applying glue to ensure an effective bonding area. Compared with the structure with a release paper layer 1 and a bonding adhesive layer 2, although there is an additional step of applying glue, it can avoid the situation where the bonding surface area is insufficient or the bonding area is too large due to improper tearing of the release paper layer 1.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
