Description

Technical Field

[0001] This utility model relates to the field of doors and windows, and more specifically, to a sliding window structure. Background Technology

[0002] Sliding windows, as a common window structure, are characterized by their ability to open and close via horizontal sliding. Traditional sliding windows' vertical profile system mainly consists of edge sealing material, smooth sash material, and hook sash material forming a closed frame. However, the way the window sash (a combination of smooth sash material and hook sash material) is fitted with the edge sealing material in existing technologies has significant flaws.

[0003] Specifically, when the window is closed, its sealing performance relies solely on the weatherstripping on both sides of the window sash for single-point sealing. Some products even omit the weatherstripping installation during the manufacturing process, resulting in a significant reduction in overall sealing efficiency.

[0004] The limitations of the current technical solution are mainly reflected in the following aspects: First, the design flaws in the combination structure of the edge seal and the weatherstripping allow moisture to penetrate and air to circulate directly in windy and rainy weather. Even with weatherstripping, it is difficult to effectively prevent wind and rain from entering the room, easily leading to problems such as water leakage and wind whistling. Second, the weatherstripping is exposed for a long time without the protective structure of the edge seal, causing the window frame to bear excessive wind pressure loads in extreme weather such as typhoons and rainstorms, seriously affecting the structural stability and service life of the profile. In addition, the inherent defects of weatherstripping sealing—such as rapid elastic decay and insufficient clamping force—prevent it from forming a continuous airtight surface, resulting in the risk of leakage at multiple points and making it difficult to meet the high standards of airtightness and watertightness required by modern buildings. Utility Model Content

[0005] Therefore, in order to solve the problem of the relatively poor airtightness of traditional sliding windows, this utility model provides a sliding window structure, the specific technical solution of which is as follows:

[0006] A sliding window structure, including

[0007] A window sash assembly, wherein a first abutting block is provided on one side of the window sash assembly, the first abutting block includes a first insertion part and a first abutting part with an arc-shaped outer contour, the first abutting part is connected to the first insertion part, and the first insertion part is inserted into the window sash assembly;

[0008] A window frame assembly is provided with a first groove, and a second abutting block that matches the first abutting part is provided in the first groove. The second abutting block is connected to the window frame assembly. When the window sash assembly is closed, the second abutting block seals against the first abutting part.

[0009] The push-pull window structure forms a surface contact pressure distribution when the sash is closed by the precise matching of the circular arc profile of the first abutting part and the second abutting block, replacing the linear contact sealing of the traditional wool strip. By combining the blockage theory (direct channel for medium penetration) and the interference theory (elastic deformation compensation gap), a continuous and uninterrupted sealing interface is constructed to avoid local leakage points caused by uneven compression of the wool strip. The circular arc abutting part guides the wind pressure load to the window frame body through geometric curvature, reducing local stress concentration of the sash and avoiding plastic deformation of the profile caused by repeated wind vibration. The interference fit of the double abutting blocks forms a labyrinth type waterproof path, which can effectively block capillary water seepage. The push-pull window structure solves the problem of general air tightness of traditional push-pull windows.

[0010] Further, the second abutting block comprises a second abutting part and a second inserting part, the second inserting part is inserted on the window frame assembly, one end surface of the second inserting part is connected with the second abutting part, and the other end surface of the second abutting part is sealed and abutted with the first abutting part when the sash assembly is closed.

[0011] Further, the window frame assembly comprises a first connecting part, a second connecting part and a third connecting part connected in sequence, and the first connecting part, the second connecting part and the third connecting part form the first slot.

[0012] Further, the first connecting part is provided with a first C-shaped groove, the third connecting part is provided with a second C-shaped groove, a first sealing rubber strip is inserted in the first C-shaped groove, and a second sealing rubber strip is inserted in the second C-shaped groove; the first sealing rubber strip and the second sealing rubber strip are respectively sealed and abutted with the sash assembly when the sash assembly is closed.

[0013] Further, a first cavity is formed between the first inserting part and the first abutting part.

[0014] Further, a second cavity is formed between the second abutting part and the second inserting part.

[0015] Further, the first sealing rubber strip is provided with a first inclined surface inclined outward.

[0016] Further, the second sealing rubber strip is provided with a second inclined surface inclined outward. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the utility model is further described in detail below in combination with its embodiments.

[0024] It should be noted that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. Where an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements can also be present. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0026] The "first", "second" in the utility model does not represent the specific quantity and order, only for the name of the distinction.

[0027] As Figure 1The utility model discloses a kind of push-pull window structures as shown in Fig. 3, one embodiment of the utility model, including sash assembly 1 and window frame assembly 2, first abutment block 3 is equipped on the side surface of sash assembly 1, first abutment block 3 includes first inserting part 31 and the first abutment part 32 of outer contour is round, the first abutment part 32 is connected with the first inserting part 31, and the first inserting part 31 is inserted on sash assembly 1;First slot 4 is equipped on window frame assembly 2, second abutment block 5 is equipped in first slot 4, and the second abutment block 5 is matched with the first abutment part 32, the second abutment block 5 is connected with window frame assembly 2, when sash assembly 1 is closed, the second abutment fast and the first abutment part 32 sealing abut.

[0028] The push-pull window structure described above, through the round arc profile of first abutment part 32 and the accurate matching of second abutment block 5, forms face contact pressure distribution when sash is closed, replaces the line contact sealing of traditional wool. By the combination of blocking theory (direct channel of blocking medium penetration) and interference theory (elastic deformation compensation gap), a continuous and uninterrupted sealing interface is constructed, and local leakage points generated by uneven compression of wool are avoided. The arc-shaped abutment part guides the wind pressure load to the window frame body through geometric curvature, reduces the local stress concentration of sash, and avoids the plastic deformation of profile caused by repeated wind vibration. The interference fit of double abutment blocks forms a labyrinth type waterproof path, which can effectively block capillary water seepage. The push-pull window structure solves the problem of general air tightness of traditional push-pull window.

[0029] As Figure 1 2 shows, in one of the embodiments, the second abutment block 5 includes second abutment part 51 and second inserting part 52, the second inserting part 52 is inserted on the window frame assembly 2, and the second inserting part 52 is connected with one end surface of the second abutment part 51, when the sash assembly 1 is closed, the other end surface of the second abutment part 51 and the first abutment part 32 sealing abut. In this way, by being provided with second inserting part 52, it is convenient to replace second abutment block 5.

[0030] As Figure 1As shown in Figure 2, in one embodiment, the window frame assembly 2 includes a first connecting portion 21, a second connecting portion 22, and a third connecting portion 23 connected in sequence, forming the first groove 4. The first connecting portion 21 has a first C-shaped groove, and the third connecting portion 23 has a second C-shaped groove. A first sealing strip 6 is inserted into the first C-shaped groove, and a second sealing strip 7 is inserted into the second C-shaped groove. When the window sash assembly 1 is closed, the first sealing strip 6 and the second sealing strip 7 respectively seal against the window sash assembly 1. Thus, by embedding the first sealing strip 6 and the second sealing strip 7 into both sides of the window frame through the C-shaped grooves, a double-sided line seal is formed with the window sash assembly 1. Combined with the surface seal formed by the double abutment blocks, a "line-surface-line" quadruple sealing barrier is constructed, improving the airtightness of the sliding window structure.

[0031] like Figure 1 As shown in Figure 2, in one embodiment, a first cavity 8 is formed between the first insertion portion 31 and the first abutting portion 32; a second cavity 9 is formed between the second abutting portion 51 and the second insertion portion 52. Thus, the first cavity 8 and the second cavity 9 serve as built-in buffer layers, guiding stress to be evenly distributed along the profile axis through optimized cavity cross-sectional geometry. Under instantaneous impact loads (such as window sash collisions), the cavities absorb impact energy through material compression deformation, and the remaining energy is guided through the cavity walls to the window frame body, reducing the impact on the window frame body.

[0032] like Figure 1 As shown in Figure 2, in one embodiment, the first sealing strip 6 has a first inclined surface 10 facing outwards; the second sealing strip 7 has a second inclined surface 11 facing outwards. Thus, by providing the first inclined surface 10 and the second inclined surface 11, it is convenient for the window sash assembly 1 to enter the first groove 4.

[0033] In one embodiment, both the first sealing strip 6 and the second sealing strip 7 are automotive-grade EDPM strips.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
