Description

Technical Field

[0001] This utility model belongs to the field of window sealing technology, and in particular relates to a rubber strip sealing structure for window frames. Background Technology

[0002] Window frame sealing strips are seals applied to window frames, such as those used to connect the window frame and the glass. Common materials include EPDM rubber, silicone, and PVC. They can improve the sealing between the window frame and the glass, preventing external factors such as rain and noise from interfering with the life or work of people inside.

[0003] However, the existing window frame sealing strips have the following problems when used:

[0004] Because the window frames are square in different sizes, if the sealing strip does not provide sufficient support, gaps may form between the sealing strip and the window sash during use, affecting the airtightness of the doors and windows. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art, solve or at least alleviate the problem that gaps easily form between the existing sealing strips and the window sash, and provide a sealing strip structure for window frames.

[0006] This utility model is achieved through the following technical solution:

[0007] A rubber strip sealing structure for a window frame is fixedly installed on the inner periphery of the window frame and abuts against the outer periphery of the window sash. It includes a central rubber strip made of hard rubber, shaped like a "U" and with an L-shaped cross-section. A snap-fit ​​strip is provided along the length of the outer side of the middle of the horizontal section of the central rubber strip, fitting into the middle of the inner periphery of the window frame. The vertical section of the central rubber strip is located on the side closest to the outside, and a sealing section is provided at the upper end of the vertical section, angled inwards and downwards, abutting against the outer side of the window sash.

[0008] To further realize this utility model, the following technical solutions may be preferred:

[0009] Preferably, the central adhesive strip includes corner segments at the four corners and adhesive strip segments at the four sides. The corner segments are L-shaped, and the adhesive strip segments are straight. The two ends of the adhesive strip segments are respectively connected to the ends of the two corner segments.

[0010] The end of the adhesive corner segment is provided with an outwardly protruding positioning boss, and the vertical section of the adhesive strip segment is provided with a positioning groove, and the positioning boss is fitted into the positioning groove.

[0011] Preferably, the end of the adhesive corner segment is further provided with a protruding positioning plate, and when the positioning boss is fitted into the positioning groove, the positioning plate is attached to the side wall of the adhesive strip segment.

[0012] Preferably, it also includes a foam strip, which is made of a soft foam material and is shaped like a square and located on the side of the central strip closest to the interior.

[0013] Preferably, the cross-section of the foam strip is Z-shaped, with the lower horizontal section of the foam strip fitting into the inner periphery of the window frame, and the upper horizontal section of the foam strip adhering to the upper side of the horizontal section of the central strip.

[0014] The beneficial effects of this utility model through the above technical solution are:

[0015] The central rubber strip of this invention has an L-shaped cross-section, which can ensure the supporting effect of the central rubber strip. A sealing section is provided at the upper end of the vertical section, and an angle is formed between the sealing section and the vertical section. The elasticity of the central rubber strip itself can ensure that the sealing section fits tightly to the window sash. Attached Figure Description

[0024] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Example

[0026] like Figures 1-7 As shown, a rubber strip sealing structure for a window frame is fixedly installed on the inner periphery of the window frame 8 and abuts against the outer periphery of the window sash 9. The structure is characterized by including a central rubber strip 1 made of hard rubber, the central rubber strip 1 being U-shaped with an L-shaped cross-section, a snap-fit ​​strip 2 provided along its length on the outer side of the middle of the horizontal section of the central rubber strip 1, the snap-fit ​​strip 2 being fitted into the middle of the inner periphery of the window frame 8, and a sealing section 3 located on the side closest to the outside of the central rubber strip 1, the upper end of the vertical section of the central rubber strip 1 being inclined inwards and downwards, the sealing section 3 abutting against the outer side of the window sash 9.

[0027] In order to reduce the number of specifications and models of the rubber strip and to be suitable for window frames of various sizes, the central rubber strip 1 includes corner rubber sections 101 at the four corners and rubber strip sections 102 at the four sides. The corner rubber sections 101 are L-shaped and the rubber strip sections 102 are straight. The two ends of the rubber strip sections 102 are respectively connected to the ends of the two corner rubber sections 101.

[0028] The end of the adhesive corner segment 101 is provided with an outwardly protruding positioning boss 5, and the vertical segment of the adhesive strip segment 102 is provided with a positioning groove 6, and the positioning boss 5 is fitted into the positioning groove 6.

[0029] In order to improve the sealing between the corner section 101 and the strip section 102, the end of the corner section 101 is also provided with a protruding positioning plate 7. When the positioning boss 5 is fitted into the positioning groove 6, the positioning plate 7 is attached to the side wall of the strip section 102.

[0030] To further improve the sealing performance, a foam strip 4 is also included. The foam strip 4 is made of soft foam material. The foam strip 4 is shaped like a square and is located on the side of the central strip 1 closest to the interior. The foam strip 4 can be directly bent and installed to achieve continuous sealing, making processing more convenient, while improving the heat insulation, sound insulation and sealing performance of the window.

[0031] The cross-section of the foam strip 4 is Z-shaped. The horizontal section of the lower side of the foam strip 4 is fitted into the inner periphery of the window frame 8, and the horizontal section of the upper side of the foam strip 4 is attached to the upper side of the horizontal section of the central strip 1. The central strip 1 and the foam strip 4 can be flexibly matched. When this structure is used on other series of windows, only the foam strip 4 needs to be changed, and the central strip 1 does not need to be adjusted, thus reducing the types and quantities of stock.

[0032] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
