Description

Technical Field

[0001] The utility model relates to the technical field of plastic-steel windows, in particular to a protective device used on plastic-steel windows. Background Art

[0002] In daily life, plastic-steel windows are widely used in various building structures due to their good thermal insulation, sound insulation and waterproof properties. However, there are often certain gaps between plastic-steel windows and window frames. These gaps can easily become channels for external impurities, dirt or living things (such as insects, dust, etc.) to enter the room during long-term use. This not only affects the cleanliness of the room and the living environment, but may also cause certain interference or damage to the normal use of the plastic-steel windows.

[0003] Traditional solutions usually involve filling gaps with sealant or installing sealing strips. However, these methods often have some problems in practical applications. For example, sealants may age and crack after long-term use, resulting in a decrease in sealing performance. While sealing strips can block external impurities to a certain extent, their installation and replacement are relatively cumbersome and can easily leave new gaps due to size mismatch or improper installation.

[0004] Therefore, in order to more effectively solve the problem caused by the gap between the plastic-steel window and the window frame, a new type of protective device is needed, which can effectively prevent external impurities, dirt or living things from entering the room, and ensure the convenience of installation and durability of the protective device. Utility Model Content

[0005] The technical problem to be solved by the utility model is to address the deficiencies of the existing technology and provide a protective device for plastic-steel windows that can block the gap between the bottom wall of the plastic-steel window and the window frame to prevent external impurities, dirt or living things from entering the room.

[0006] The technical problem to be solved by the utility model is achieved through the following technical solutions: a protective device for a plastic-steel window, which is installed between the plastic-steel window and the window frame, and the protective device includes:

[0007] A protective vertical plate is placed between the bottom outer wall of the plastic-steel window and the window frame, one side of the protective vertical plate is set as a protective vertical plate fixing surface, and the other side is set as a protective vertical plate protective surface. A colloid is fixedly provided on the protective vertical plate fixing surface, and the protective vertical plate is fixedly bonded to the bottom outer wall of the plastic-steel window by the colloid. The area of ​​the protective vertical plate protective surface located above the window frame forms an upper protective surface, and the area of ​​the protective vertical plate protective surface located below the window frame forms a lower protective surface. A horizontal brush is fixedly provided on the lower protective surface of the protective vertical plate protective surface so as to be in continuous contact with the window frame facade when the plastic-steel window is pushed or pulled;

[0008] It also includes a protective horizontal plate, which is vertically fixed to the upper protective surface of the protective vertical plate, with the top surface of the protective horizontal plate facing the glass of the plastic-steel window and the bottom surface facing the window frame. A vertical brush is fixed on the bottom surface of the protective horizontal plate so as to be in continuous contact with the horizontal surface of the window frame when the plastic-steel window is pushed or pulled;

[0009] The gap between the plastic-steel window and the window frame is closed by the horizontal and vertical brushes, thereby forming a brush-blocking barrier.

[0010] The technical problem to be solved by the present invention can also be achieved through the following technical solutions. In the above-mentioned protective device for plastic-steel windows, the colloid is fixed to the upper area of ​​the fixing surface of the protective vertical plate, thereby forming a gap between the lower area of ​​the fixing surface of the protective vertical plate and the bottom wall of the window frame for the lower part of the protective vertical plate to undergo slight deformation.

[0011] The technical problem to be solved by the present invention can also be achieved through the following technical solutions: the above-mentioned protective device for plastic-steel windows, the outer facade of the protective horizontal plate is flush with the outer facade of the window frame.

[0012] Compared with the prior art, the beneficial technical effects of the present invention are:

[0013] (1) By designing protective vertical plates and protective horizontal plates, and combining horizontal and vertical brushes, the device can fit tightly into the gap between the plastic-steel window and the window frame, forming a solid brush barrier, fundamentally preventing the intrusion of external impurities, dirt, dust, and living things (such as insects), significantly improving the cleanliness of the room and the comfort of the living environment;

[0014] (2) The colloid fixing method on the protective vertical plate and the slight deformation gap reserved at the bottom of the protective vertical plate enable the device to adapt to plastic-steel windows of different sizes and the slight deformation that may occur during long-term use. This design ensures the stability and durability of the device in different environments and reduces the problem of sealing failure caused by size mismatch or improper installation;

[0015] (3) The protective device adopts a simple adhesive fixing method, which does not require complicated installation steps or tools, greatly simplifying the installation process. At the same time, due to the overall simplicity of the structure, low cost and low maintenance cost, it can be replaced by itself after a certain period of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following further describes the specific technical solutions of the present invention with reference to the accompanying drawings, so as to facilitate further understanding of the present invention by those skilled in the art, and does not constitute a limitation to their rights.

[0021] Example 1, reference Figure 1-3 , a protective device for a plastic-steel window, which is installed between the plastic-steel window 1 and the window frame 2, and the protective device includes;

[0022] The protective vertical plate 3 is formed into a roughly square plate-shaped structure, and its outer wall of the plastic-steel window 1 is parallel to the outer wall of the bottom of the plastic-steel window 1 and is placed between the outer wall of the bottom of the plastic-steel window 1 and the window frame 2. One side of the protective vertical plate 3 is set as a fixing surface of the protective vertical plate 3, and the other side is set as a protective surface of the protective vertical plate 3. A colloid 4 is fixedly provided on the fixing surface of the protective vertical plate 3. The protective vertical plate 3 is fixedly bonded to the outer wall of the bottom of the plastic-steel window 1 through the colloid 4. The protective surface of the protective vertical plate 3 is located in an area above the window frame 2 to form an upper protective surface, and the protective surface of the protective vertical plate 3 is located in an area below the window frame 2 to form a lower protective surface. A horizontal brush 5 is fixed on the lower protective surface of the protective surface of the protective vertical plate 3, which can be in continuous contact with the facade of the window frame 2 when pushing and pulling the plastic-steel window 1. The horizontal brush 5 can be made of soft plastic material;

[0023] The colloid 4 is fixed to the upper area of ​​the fixed surface of the protective riser 3, thereby forming a gap 6 between the lower area of ​​the fixed surface of the protective riser 3 and the bottom wall of the window frame 2, which allows the lower part of the protective riser 3 to undergo slight deformation. This gap 6 enables the device to adapt to plastic-steel windows 1 of different sizes and slight deformations that may occur during long-term use, ensuring the stability and durability of the device in different environments and reducing the problem of sealing failure caused by size mismatch or improper installation.

[0024] The protective horizontal plate 7 is formed into a substantially square plate-shaped structure and is vertically fixed to the upper protective surface of the protective vertical plate 3. The top surface of the protective horizontal plate 7 faces the glass of the plastic-steel window 1, and the bottom surface faces the window frame 2. A vertical grinding brush 8 is fixed to the bottom surface of the protective horizontal plate 7 so as to be in continuous contact with the horizontal surface of the window frame 2 when the plastic-steel window 1 is pushed or pulled. The vertical grinding brush 8 faces vertically downward and can be made of soft plastic. The outer surface of the protective horizontal plate 7 is flush with the outer surface of the window frame 2.

[0025] The horizontal brushes 5 and the vertical brushes 8 close the gap between the plastic-steel window 1 and the window frame 2, thereby forming a brush barrier. That is, when the plastic-steel window 1 is pushed or pulled, the vertical brushes 8 are in constant contact with the top surface of the window frame 2, so that no impurities, dirt, or living things outside can enter the room through the gap between the window frame 2 and the plastic-steel window 1, thus forming a first line of protection. The horizontal brushes 5 are in constant contact with the inner wall of the window frame 2, further preventing impurities, dirt, or living things from entering the room, thereby forming a second line of protection.

[0026] When using the protective device, it is only necessary to horizontally bond the colloid 4 of the protective device to the bottom wall of the plastic-steel window 1 before installing the plastic-steel window 1. No complicated installation steps or tools are required, which greatly simplifies the installation process. At the same time, due to the overall simplicity of the structure, low cost and low maintenance cost, it can be replaced by yourself after a certain period of use.
