Description

A type of PVC window with dustproof function Technical Field

[0001] This utility model relates to the field of PVC window technology, specifically a PVC window with dustproof function. Background Technology

[0002] PVC windows and doors are made primarily of polyvinyl chloride resin, with added stabilizers, colorants, fillers, UV absorbers, etc. The resin is extruded into profiles, which are then cut, welded, or screwed together to form window and door frames. Sealing strips, weatherstripping, and hardware are then added. To enhance the rigidity of the profiles, steel reinforcement is added to the cavities of profiles exceeding a certain length. Windows and doors made in this way are called PVC windows and doors.

[0003] The existing technical solution has at least the following drawbacks: During prolonged sliding, the rubber seals between the PVC window and the frame wear down, creating gaps that allow dust to enter the room. Therefore, we propose a PVC window with dustproof functionality. Summary of the Invention

[0004] The purpose of this utility model is to provide a PVC window with dustproof function, which solves the problem mentioned in the background art that the rubber seal between the PVC window and the window frame will wear out during long-term sliding of the existing PVC window. After the rubber seal wears out, a gap will be created between the PVC window and the window frame, which will lead to the entry of external dust into the room.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PVC window with dustproof function, comprising a window frame body, a support rod integrally formed in the middle of the window frame body, PVC window bodies on both sides of the window frame body, a fixing strip on the side of the PVC window body near the support rod, an arc-shaped rubber plate on the outer side of the fixing strip, a slot in the middle of the fixing strip, a retaining strip fixedly installed on the side of the arc-shaped rubber plate near the slot, hinge seats fixedly installed at both ends of the fixing strip, and a limit rod rotatably installed on one side of the hinge seat.

[0006] By adopting the above technical solution, the return spring can keep the arc-shaped rubber plate in constant contact with the surface of the window frame, thus ensuring a dustproof effect when the PVC window is closed. Furthermore, because the arc-shaped rubber plate remains in contact with the window frame, it maintains a tight seal even after wear during prolonged sliding, effectively preventing external dust from entering the room. When the arc-shaped rubber plate becomes excessively worn, the limiting rod can be flipped to separate it from the plate, and the locking strip on the plate can be pulled to separate it from the groove, facilitating easy removal and replacement of the arc-shaped rubber plate, further improving the dustproof effect of the PVC window.

[0007] Optionally, a return spring is fixedly installed at the upper end of the hinge seat, and the other end of the return spring is fixedly connected to the limiting rod.

[0008] By adopting the above technical solution and setting the reset spring, the limit rod can be driven to abut against the bottom of the arc-shaped rubber plate.

[0009] Optionally, the size of the card strip is adapted to the size of the card slot, and the card strip and the card slot are movably connected.

[0010] By adopting the above technical solution, the arc-shaped rubber sheet can be installed or removed through the cooperation of the clip and the slot.

[0011] Optionally, the limiting rod is located below the arc-shaped rubber plate, and the limiting rods are arranged symmetrically.

[0012] By adopting the above technical solution and setting the limiting rod, the arc-shaped rubber plate can be supported and limited.

[0013] Optionally, the fixing strip is fixedly connected to the PVC window body, and the length of the fixing strip is the same as the length of the PVC window body.

[0014] By adopting the above technical solution and setting the fixing strip, the arc-shaped rubber sheet can be installed and supported.

[0015] Optionally, the support rod is located in the middle of the window frame body, and the arc-shaped rubber plate is attached to the outer side of the support rod.

[0016] By adopting the above technical solution and setting the support rod, the arc-shaped rubber plate can be made to fit and seal with the support rod, thereby reducing the entry of external dust.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] This technical solution, through the design of a window frame body, a PVC window body, an arc-shaped rubber plate, a hinge seat, a limiting rod, and a return spring, ensures that the return spring keeps the arc-shaped rubber plate in constant contact with the surface of the window frame body. This guarantees a dustproof effect when the PVC window body is closed. Furthermore, because the arc-shaped rubber plate remains in contact with the window frame body, it maintains a tight seal even after wear during prolonged sliding, effectively preventing external dust from entering the room. When the arc-shaped rubber plate becomes excessively worn, the limiting rod can be flipped to separate it from the arc-shaped rubber plate, and the locking strip on the arc-shaped rubber plate can be pulled to separate it from the slot, facilitating the removal and replacement of the arc-shaped rubber plate, further improving the dustproof effect of the PVC window body.

[0025] Please refer to Figures 1-4. This utility model provides a technical solution: a PVC window with dustproof function, including a window frame body 1. A support rod 11 is integrally formed in the middle of the window frame body 1. PVC window bodies 12 are provided on both sides of the window frame body 1. A fixing strip 21 is provided on the side of the PVC window body 12 near the support rod 11. An arc-shaped rubber plate 2 is provided on the outer side of the fixing strip 21. A slot 22 is opened in the middle of the fixing strip 21. A retaining strip 23 is fixedly installed on the side of the arc-shaped rubber plate 2 near the slot 22. Hinges 3 are fixedly installed at both ends of the fixing strip 21. A limit rod 4 is rotatably installed on one side of the hinge 3 to limit movement. Rod 4 is positioned below the curved rubber plate 2, and the limiting rods 4 are symmetrically arranged. The limiting rods 4 can support and limit the curved rubber plate 2. The fixing strip 21 is fixedly connected to the PVC window body 12, and the length of the fixing strip 21 is the same as the length of the PVC window body 12. The fixing strip 21 can be used to install and support the curved rubber plate 2. The support rod 11 is located in the middle of the window frame body 1, and the curved rubber plate 2 is in contact with the outer side of the support rod 11. The support rod 11 can make the curved rubber plate 2 and the support rod 11 come into contact and seal, thereby reducing the entry of external dust.

[0026] A return spring 5 is fixedly installed on the upper end of the hinge seat 3. The other end of the return spring 5 is fixedly connected to the limit rod 4. By setting the return spring 5, the limit rod 4 can be driven to abut against the lower part of the arc-shaped rubber plate 2.

[0027] The size of the clip 23 is adapted to the size of the slot 22, and the clip 23 and the slot 22 are movably connected. By cooperating with the slot 22, the arc-shaped rubber plate 2 can be installed or removed.

[0028] During sealing, the position of the arc-shaped rubber plate 2 is limited by the limiting rod 4 on the hinge seat 3. At the same time, thanks to the spring's elasticity, the return spring 5 keeps the arc-shaped rubber plate 2 in contact with the surface of the window frame body 1, thus ensuring that the PVC window body 12 can prevent dust when closed. Moreover, since the arc-shaped rubber plate 2 is always in contact with the window frame body 1, it ensures that even if the arc-shaped rubber plate 2 wears down during long-term pushing and pulling, it can still maintain a tight seal, effectively preventing external dust from entering the room. When the arc-shaped rubber plate 2 is worn excessively, the limiting rod 4 can be flipped to separate the limiting rod 4 from the arc-shaped rubber plate 2, and then the retaining strip 23 on the arc-shaped rubber plate 2 can be pulled to separate it from the retaining groove 22, making it easy to remove and replace the arc-shaped rubber plate 2, further improving the dustproof effect of the PVC window body 12.
