Description

Technical Field

[0001] The utility model relates to the technical field of door and window profiles, and particularly relates to a splicing plug-in structure for the connection of combined doors and windows and doors and windows thereof. Background Art

[0002] With the continuous improvement of people's requirements for the comfort of the living environment, large-grid window types or French windows are becoming more and more popular. The reasons for using combined doors and windows for large-grid window types or French windows usually include: (1) the window is too large and exceeds the length of the profile; (2) strength requirements; (3) the window type design is relatively complex.

[0003] In the existing door and window technology field, a splicing frame (splicing strip or splicing pipe) is often used to connect between two or more doors, or between windows, or between a door and a window, as Figure 1 shown, to form a combined door and window. Connecting the splicing frame with screws in a single direction can enhance the strength, and applying sealant can ensure the watertight performance at the splicing part. However, the visible surface of the profile at the splicing part is very wide, which reduces the transparency effect of large-grid window types or French windows, and the splicing seam is visible and not beautiful.

[0004] Another less common connection method is to directly splice two windows, as Figure 2 shown. Connecting with screws in a single direction can improve the strength, but the improvement effect is slightly worse than that of using a splicing frame. The visible surface of the profile is still very wide but slightly smaller than that of using a splicing frame. The splicing seam is visible and not beautiful. Most importantly, direct splicing cannot ensure the watertight performance at the splicing part. Content of the Utility Model

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components. For those of ordinary skill in the art, the specific meaning of the terms in the present utility model can be understood according to specific circumstances.

[0036] The present utility model discloses a door and window, which includes at least two window frames 2, and a splicing insertion structure for combining the joints of the door and window is provided between the two window frames 2. It can realize the combination of large-grid window types or French windows, and while improving the strength, the sealing performance is also guaranteed.

[0037] See Figures 1-4 , the splicing insertion structure for combining the joints of the door and window in this solution includes a first splicing frame assembly 10 and a second splicing frame assembly 20. The first splicing frame assembly 10 serves as one side of a window frame in the combined door and window; the second splicing frame assembly 20 serves as the other side of a window frame in the combined door and window. The first splicing frame assembly 10 and the second splicing frame assembly 20 are inserted into each other to realize the splicing of two adjacent window frames 2; after the first splicing frame assembly 10 and the second splicing frame assembly 20 are inserted into each other, they are fixedly connected by a connecting piece to form a splicing insertion structure, and there are no splicing seams on the outer front surface 101 and the inner front surface 102 of the splicing insertion structure.

[0038] Compared with the prior art, the splicing insertion structure in this solution is arranged at the joint between the window frames 2 of the combined door and window. The first splicing frame assembly 10 and the second splicing frame assembly 20 are connected by inserting into each other, and while maintaining sufficient strength, the width of the visible surface is reduced as much as possible. At the same time, there are no splicing seams on the outer front surface 101 and the inner front surface 102 of the visible splicing insertion structure. The visual surface effect of this splicing insertion structure is similar to that of the mullion. Compared with the existing splicing structures, its appearance is more concise and beautiful, convenient for installation, and has better strength.

[0039] In this embodiment, the first mullion frame assembly 10 includes a first inner splicing member 11 and a first outer splicing member 12, and the second mullion frame assembly 20 includes a second inner splicing member 21 and a second outer splicing member 22. The first inner splicing member 11 is inserted into the second inner splicing member 21 so that the inner end surface 111 of the first inner splicing member or the inner end surface 211 of the second inner splicing member forms the inner front surface 102 of the mullion splicing structure; the first outer splicing member 12 is inserted into the second outer splicing member 22 so that the outer end surface 121 of the first outer splicing member or the outer end surface 221 of the second outer splicing member forms the outer front surface 101 of the mullion splicing structure. Wherein, heat insulation connecting rubber strips 40 are provided between the first inner splicing member 11 and the first outer splicing member 12 and between the second inner splicing member 21 and the second outer splicing member 22. The first inner splicing member 11 and the first outer splicing member 12 are respectively connected to the window frame profile 201 and the window frame glass 202 of a window frame 2 to fix the window frame glass 202. The second inner splicing member 21 and the second outer splicing member 22 are respectively connected to the window frame profile 201 and the window frame glass 202 of another window frame 2 to fix the window frame glass 202.

[0040] In this embodiment, an inner hidden plate 1111 is provided on the inner end surface 111 of the first inner splicing member, and the inner hidden plate 1111 extends to the inner end surface 211 of the second inner splicing member, so that the inner end surface 211 of the second inner splicing member abuts against the inner hidden plate 1111, and only the inner hidden plate 1111 is shown on the inner front surface 102 of the mullion splicing structure.

[0041] In this embodiment, the connecting member includes a first connecting member 31 and a second connecting member 32. The first connecting member 31 is inserted through the inner hidden plate 1111 of the first inner splicing member 11 and the inner end surface 211 of the second inner splicing member along the first direction, and the second connecting member 32 is inserted through the inner side surface 112 of the first inner splicing member and the inner side surface 212 of the second inner splicing member along the second direction. It should be noted that the first direction is the same as the width direction of the window frame 2, and the second direction is perpendicular to the first direction and is the insertion direction of the first inner splicing member 11 and the second inner splicing member 21. By respectively arranging the first connecting member 31 and the second connecting member 32 in two directions for connecting between the first mullion frame assembly 10 and the second mullion frame assembly 20, the connection strength can be greatly improved.

[0042] In this embodiment, the inner hidden plate 1111 of the first inner splicing member 11 extends towards the inner front surface 102 of the window frame 2 and is provided with a connector installation groove 1112. The first connector 31 penetrates into the inner hidden plate 1111 of the first inner splicing member 11 and the inner end surface 211 of the second inner splicing member in the first direction through the connector installation groove 1112. The notch of the connector installation groove 1112 is covered with a cover plate 50, and the outer surface 51 of the cover plate 50 forms the inner front surface 102 of the mullion splicing structure. The setting of the connector installation groove 1112 is for facilitating the installation of the first connector 31. The cover plate 50 covering the outside of the connector installation groove 1112 not only ensures that there is no splicing seam on the inner front surface 102, but also avoids the exposure of the first connector 31, improving the aesthetic appearance.

[0043] In this embodiment, the outer end surface 121 of the first outer splicing member is provided with an outer hidden portion 1211. The outer hidden portion 1211 extends to the outer end surface 221 of the second outer splicing member. The outer end surface 221 of the second outer splicing member abuts against the outer hidden portion 1211, so that the splicing seam between the first outer splicing member 12 and the second outer splicing member 22 is formed on the outer side surface 103 of the mullion splicing structure, and only the outer hidden portion 1211 is shown on the outer front surface 101 of the mullion splicing structure.

[0044] In this embodiment, the connector further includes a third connector 33. The third connector 33 penetrates between the inner side surface 122 of the first outer splicing member and the inner side surface 222 of the second outer splicing member in the second direction. The third connector 33 is installed in the same direction as the second connector 32, which can further strengthen the connection between the first mullion frame assembly 10 and the second mullion frame assembly 20.

[0045] It can be understood that the first inner splicing member 11 and the second inner splicing member 21 are respectively provided with cavities for avoiding the second connector 32 to facilitate the installation of the second connector 32; the first outer splicing member 12 and the second outer splicing member 22 are respectively provided with cavities for avoiding the third connector 33 to facilitate the installation of the third connector 33.

[0046] In this embodiment, the first inner splicing member 11 is provided with a first insertion portion 113 and a second insertion portion 114, and the second inner splicing member 21 is provided with a third insertion portion 213 and a fourth insertion portion 214. The first insertion portion 113 is inserted and fixed with the third insertion portion 213, and the second insertion portion 114 is inserted and fixed with the fourth insertion portion 214. Among them, both the first insertion portion 113 and the fourth insertion portion 214 are convex insertion portions, and both the second insertion portion 114 and the third insertion portion 213 are concave insertion portions. It should be noted that both the first insertion portion 113 and the fourth insertion portion 214 are convex members, and both the second insertion portion 114 and the third insertion portion 213 are concave grooves. The insertion directions of the first insertion portion 113 and the third insertion portion 213 in this solution are opposite to the insertion directions of the second insertion portion 114 and the fourth insertion portion 214, forming a complementarity, which improves the connection strength and stability of the insertion structure. It can be understood that caulking treatment is performed at one of the insertion joints between the first insertion portion 113 and the third insertion portion 213 and the insertion joint between the second insertion portion 114 and the fourth insertion portion 214, or caulking treatment is performed on both, so as to enhance the airtightness and watertightness of the door and window joints.

[0047] It should be noted that the following specific implementation manners also exist for the first insertion portion, the second insertion portion, the third insertion portion, and the fourth insertion portion of this solution:

[0048] 1) The first insertion portion and the fourth insertion portion are set as concave insertion portions, and the second insertion portion and the third insertion portion are set as convex insertion portions;

[0049] 2) The first insertion portion and the second insertion portion are set as convex insertion portions, and the third insertion portion and the fourth insertion portion are set as concave insertion portions;

[0050] 3) The first insertion portion and the second insertion portion are set as concave insertion portions, and the third insertion portion and the fourth insertion portion are set as convex insertion portions.

[0051] It can be understood that in order to increase the sealing performance, the number of the first insertion portion, the second insertion portion, the third insertion portion, and the fourth insertion portion can be increased according to requirements. A third rubber strip 63 can be arranged between the first inner splicing member 11 and the second inner splicing member 21, as Figure 5 shown.

[0052] In this embodiment, a first sealing rubber strip 61 is provided between the outer end surface 121 of the first outer splicing member and the outer end surface 221 of the second outer splicing member, and a second sealing rubber strip 62 is provided between the inner side surface 122 of the first outer splicing member and the inner side surface 222 of the second outer splicing member. The first sealing rubber strip 61 and the second sealing rubber strip 62 further improve the airtightness and watertightness of the door and window. It can be understood that on the premise of meeting the sealing requirements, the first sealing rubber strip 61 or the second sealing rubber strip 62 can also be reduced, as Figure 6As shown in the figure. When it is necessary to enhance the sealing effect, caulking treatment can also be carried out at the contact position between the inner side surface 122 of the first outer splicing part and the inner side surface 222 of the second outer splicing part.

[0053] In this solution, by inserting and connecting the first mullion frame assembly 10 and the second mullion frame assembly 20, the visible surface width can be effectively reduced. At the same time, there are no splicing seams on both the inner front surface 102 and the outer front surface 101, which is similar to the effect of the middle mullion, improving the stability of the window and door connection.

[0054] By fixing simultaneously in two directions through the first connecting piece 31, the second connecting piece 32 and the third connecting piece 33, the connection strength of the window and door connection can be improved.

[0055] Through caulking treatment at the insertion joints of the first insertion part 113 and the third insertion part 213 and the insertion joints of the second insertion part 114 and the fourth insertion part 214, and the setting of the first sealing strip 61 and the second sealing strip 62, a four - layer sealing design is formed, improving the airtightness and watertightness of the window and door connection.

[0056] The above embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
