Description

Technical Field

[0001] This utility model relates to the field of door and window sealing components, specifically a PVC door and window sealing component with sound insulation strips. Background Technology

[0002] PVC windows and doors are made primarily from polyvinyl chloride resin, which is extruded into profiles and then cut, welded, or screwed together to form window and door frames. The sealing strips of PVC windows and doors are usually made of traditional PVC material, which is prone to aging, deformation, and breakage. In addition, traditional PVC windows and doors use single-cavity PVC profiles, which have low material density and a sound transmission loss value (STC) that is difficult to exceed 30dB. This makes it difficult to effectively block mid-to-high frequency traffic noise, further reducing the sound insulation performance. Therefore, there is an urgent need to develop a sealing component for PVC windows and doors with sound-insulating strips.

[0003] Chinese patent CN202222513190.X discloses a soundproof and fire-resistant PVC-U door and window, relating to the field of PVC-U doors and windows. This soundproof and fire-resistant PVC-U door and window includes a PVC-U door and window frame and multiple panes of glass. A mounting base is slidably connected to the outer surface of the PVC-U door and window frame, and the mounting base is connected to the PVC-U door and window frame by bolts. The multiple panes of glass are disposed inside the PVC-U door and window frame. Under the action of the sealing components, the multiple panes of glass are not compressed and fixed, allowing the glass to be separated from the PVC-U door and window frame. New glass is then inserted into the PVC-U door and window frame, and the mounting base is used for initial fixing. This reverse movement causes the two fixing frames to press against the sealing block, thereby fixing the glass and effectively achieving a sealing effect.

[0004] While existing PVC windows and doors can solve the problems of silicone sealant deformation at high temperatures, adhesion between the sealant and the window / door frame, and the difficulty in removing the sealant, making disassembly and reinstallation of the glass difficult, traffic noise, industrial noise, and residential noise in urban environments can still interfere with residents' lives and work. Consumers have increasingly higher requirements for the sound insulation performance of their living environments. Improving sound insulation performance can meet market demands and enhance the market competitiveness of products.

[0005] Therefore, a sealing component for PVC doors and windows with sound-insulating strips is proposed to address the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a plastic steel door and window sealing component with sound insulation strips to solve the problem mentioned in the background art that traffic noise, industrial noise and domestic noise in urban environments can interfere with residents' lives and work.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a plastic steel door and window sealing component with sound insulation strip, including a sealing component body, and a fixing component is integrally provided on both the upper and lower sides of the sealing component body, and a sound insulation component is movably connected to the inner side of the fixing component.

[0008] The fixing component includes an outer plate, a positioning sleeve, and a positioning screw. The positioning sleeve is connected through the interior of the outer plate, and the positioning screw is threadedly connected to the interior of the positioning sleeve.

[0009] Preferably, the fixing component further includes an anti-slip sleeve, and the outer wall of the positioning screw is glued with the anti-slip sleeve.

[0010] Preferably, the fixing component further includes an upper baffle, which is welded to the upper part of the outer wall of the outer plate.

[0011] Preferably, the fixing component further includes a lower baffle and a positioning groove. The lower baffle is welded to the lower part of the outer wall of the outer plate, and positioning grooves are reserved on both the upper and lower sides of the outer plate.

[0012] Preferably, the sound insulation component includes a positioning plate and positioning blocks, and positioning blocks are integrally provided on both the upper and lower sides of the positioning plate.

[0013] Preferably, the sound insulation component further includes a sealing gasket and a sound insulation strip. The inner wall of the positioning plate is fitted with a sealing gasket, and the side of the sealing gasket away from the positioning plate is fitted with a sound insulation strip. The top of the sealing gasket and the sound insulation strip are also fitted with positioning blocks by adhesive.

[0014] Preferably, the sealing assembly body includes a side plate and a welding plate, and the outer wall of the side plate is integrally provided with the welding plate.

[0015] The advantages of this utility model are:

[0016] 1. This utility model adopts the cooperation of the sealing component body, the fixing component and the sound insulation component. The sealing component body and the fixing component are combined with the sound insulation component. The improved plastic steel door and window sealing component can effectively improve the sound insulation performance and meet the environmental needs of increasingly serious urban noise pollution. The upper baffle and the lower baffle can prevent rainwater from splashing directly into the interior of the sealing component body, which plays a waterproof role. The bottom inner wall of the outer plate is inclined at 30 degrees. A water channel is reserved at the lowest point of the 30-degree angle, which can drain the incoming rainwater.

[0017] 2. This utility model employs the coordinated action of a positioning plate, positioning block, sealing gasket, and sound insulation strip. When the positioning screw rotates inward, it pushes the positioning plate. As the positioning plate slides inward, it squeezes and pushes the sealing gasket and sound insulation strip until they are completely fitted to the window seam. The improved sealing gasket reduces the frequency of maintenance and replacement, lowering long-term operating costs. The sound insulation strip uses high-quality sound insulation materials, such as EPDM composite strips, which improves the durability of the sealing components and reduces the decline in sound insulation performance caused by material aging.

[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.

[0026] Example 1

[0027] Please see Figures 1 to 5 As shown, a sealing component for PVC windows and doors with sound-insulating strips includes a sealing component body 1. Fixing components 2 are integrally installed on both the upper and lower sides of the sealing component body 1, and a sound-insulating component 3 is movably connected to the inner side of the fixing components 2. The fixing component 2 includes an outer plate 21, a positioning sleeve 22, and a positioning screw 23. The positioning sleeve 22 is internally connected to the outer plate 21, and the positioning screw 23 is threadedly connected to the inner side of the positioning sleeve 22. The sealing component body 1, fixing component 2, and sound-insulating component 3, combined with the improved PVC window and door sealing component, can effectively improve sound insulation performance and meet the increasingly serious environmental needs of urban noise pollution. The fixing component 2 also includes an anti-slip sleeve 24, which is glued to the outer wall of the positioning screw 23. The end of 23 is glued with an anti-slip sleeve 24. When the positioning screw 23 is rotated, the positioning plate 31 can be pushed inward. The fixing component 2 also includes an upper baffle 25. The upper baffle 25 is welded to the upper part of the outer wall of the outer plate 21. With this setting, the upper baffle 25 at the top of the outer plate 21 and the lower baffle 26 at the bottom of the outer plate 21 can prevent rainwater from splashing directly into the interior of the sealing component body 1, thus playing a waterproof role. The fixing component 2 also includes a lower baffle 26 and a positioning groove 27. The lower baffle 26 is welded to the lower part of the outer wall of the outer plate 21, and positioning grooves 27 are reserved on both the upper and lower sides of the outer plate 21. The bottom inner wall of the outer plate 21 is inclined at 30 degrees. A water channel is reserved at the lowest point of the 30-degree angle. The water channel can drain the incoming rainwater.

[0028] Example 2

[0029] like Figures 1 to 5As shown, based on Embodiment 1, this utility model provides a technical solution: the sound insulation component 3 includes a positioning plate 31 and a positioning block 32. Positioning blocks 32 are integrally provided on both the upper and lower sides of the positioning plate 31. When the positioning screw 23 rotates inward, it pushes the positioning plate 31. During the inward sliding process, the positioning plate 31 maintains a stable state through the sliding action of the positioning blocks 32 within the positioning groove 27, and maintains a straight line to push the sealing gasket 33 and the sound insulation strip 34. The sound insulation component 3 also includes a sealing gasket 33 and a sound insulation strip 34. The sealing gasket 33 is fitted to the inner wall of the positioning plate 31, and the sealing gasket 33 is far from the positioning screw 23. A sound-insulating strip 34 is attached to one side of the mounting plate 31. A positioning block 32 is also attached to the top of the sealing gasket 33 and the sound-insulating strip 34 with adhesive. The sealing gasket 33 and the sound-insulating strip 34 are completely attached to the window seam of the door and window. The improved sealing gasket 33 can reduce the frequency of maintenance and replacement and reduce long-term use costs. The sound-insulating strip 34 uses high-quality sound-insulating material. The main body 1 of the sealing component includes a side plate 11 and a welding plate 12. The outer wall of the side plate 11 is integrally provided with the welding plate 12. With this setting, the welding plate 12 on the outer wall of the side plate 11 can help to weld and fix the main body 1 of the sealing component to the outside of the door and window.

[0030] Working principle: First, the sealing component body 1 and the fixing component 2 are combined with the sound insulation component 3. The improved plastic steel door and window sealing component can effectively improve the sound insulation performance and meet the environmental needs of increasingly serious urban noise pollution. When fixing the sound insulation component 3, first rotate the positioning screw 23 inside the positioning sleeve 22 inward. The end of the positioning screw 23 is glued with an anti-slip sleeve 24. When rotating the positioning screw 23, the positioning plate 31 can be pushed inward. The upper baffle 25 on the top of the outer plate 21 and the lower baffle 26 at the bottom of the outer plate 21 can prevent rainwater from splashing directly into the interior of the sealing component body 1, which plays a waterproof role. The bottom inner wall of the outer plate 21 is inclined at 30 degrees. A water channel is reserved at the lowest point of the 30-degree angle. The water channel can drain the incoming rainwater.

[0031] Secondly, when the positioning screw 23 rotates inward, it pushes the positioning plate 31. During the inward sliding process, the positioning plate 31 remains stable due to the sliding action of the positioning block 32 inside the positioning groove 27, and pushes the sealing gasket 33 and the sound insulation strip 34 in a straight line. The sealing gasket 33 and the sound insulation strip 34 also remain in a straight line due to the sliding action of the positioning block 32 in the positioning groove 27 until the sound insulation strip 34 is completely attached to the window seam of the door and window. The improved sealing gasket 33 can reduce the frequency of maintenance and replacement, and reduce the long-term use cost. The sound insulation strip 34 uses high-quality sound insulation materials, such as EPDM composite strips, which can improve the durability of the sealing components and reduce the decline in sound insulation performance caused by material aging. The welding plate 12 on the outer wall of the side plate 11 can help to weld and fix the main body 1 of the sealing components to the outside of the door and window.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
