AI Technical Summary
Existing aluminum alloy doors and windows suffer from unstable sealing performance, high installation complexity, and poor aesthetics at the joints. They are particularly prone to air and water leakage when subjected to thermal expansion and contraction and structural deformation, which affects overall performance and service life.
The design employs a concealed splicing structure, connecting the splicing strips to the window frame with fixing screws. Combined with the design of sealant, snap-fit strips, limit snap-fit strips, and embedded blocks, the sealing performance is enhanced, and waterproofing is applied to the splicing frame.
It improves the sealing and waterproofing capabilities of doors and windows, enhances their appearance, simplifies the installation process, and extends their service life.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of hidden splicing structure technology, specifically a hidden splicing structure. Background Technology
[0002] With the development of building energy conservation, green environmental protection and modern architectural aesthetics, aluminum alloy doors and windows, as an indispensable part of the building envelope, have been widely used in various construction projects such as residential, office buildings and commercial buildings due to their advantages such as light weight, high strength, corrosion resistance, beautiful appearance, easy processing and recycling. Compared with traditional wooden and steel doors and windows, aluminum alloy doors and windows have superior comprehensive performance, especially in terms of wind pressure resistance, water tightness, air tightness, sound insulation and thermal insulation.
[0003] In recent years, with the continuous improvement of energy-saving building standards, higher requirements have been placed on the thermal insulation performance of doors and windows. Traditional ordinary aluminum alloy doors and windows, due to their high thermal conductivity, are prone to heat conduction and cannot meet the standards for high-performance energy-saving doors and windows. Therefore, thermally broken aluminum alloy door and window technology has emerged, significantly improving the thermal performance of doors and windows.
[0004] However, aluminum alloy doors and windows on the market still have problems such as unsightly joints, unstable sealing performance, and high installation complexity. In particular, the joints are prone to air and water leakage due to thermal expansion and contraction and structural deformation, which affects the overall performance and service life of the doors and windows. Utility Model Content
[0005] This invention provides a hidden splicing structure, which can effectively solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a hidden strip structure, including a first window frame and a second window frame, wherein the first window frame is connected to the second window frame by two strips;
[0007] The first and second window frames have sealant embedded on their sides.
[0008] According to the above technical solution, the splice strip and the second window frame are connected by fixing screws.
[0009] According to the above technical solution, a snap-fit strip is provided at one end of the outer side of the splice strip, and a limit snap-fit strip is provided at the other end of the outer side of the splice strip. An embedded block is provided at the inner end of both the first window frame and the second window frame.
[0010] The locking strip and the limiting locking strip contact the two embedded blocks.
[0011] According to the above technical solution, limit grooves are provided on both sides of the inner side of the first window frame and the second window frame.
[0012] According to the above technical solution, sealing strips are embedded between the first window frame, the splice strip, and the second window frame.
[0013] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, it is safe and convenient to use, the appearance is neater, and the indoor and outdoor open frame partitions are waterproofed, making it more suitable for wider promotion and use.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0021] Example: Figure 1-2 As shown, this utility model provides a technical solution: a hidden splicing strip structure, including a first window frame 1 and a second window frame 2. The first window frame 1 is connected to the second window frame 2 by two splicing strips 3. The splicing strips 3 and the second window frame 2 are embedded and connected by fixing screws 8, which facilitates better fixation. Limiting grooves 9 are provided on both sides of the inner side of the first window frame 1 and the second window frame 2, which can facilitate the installation of heat insulation strips or sealing strips.
[0022] Sealant 7 is embedded on the sides of the first window frame 1 and the second window frame 2.
[0023] A snap-fit strip 4 is provided at one end of the outer side of the splice strip 3, and a limit snap-fit strip 5 is provided at the other end of the outer side of the splice strip 3. An embedded block 6 is provided at the inner end of both the first window frame 1 and the second window frame 2.
