Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a polyurethane door and window profile. Background Technology

[0002] Doors and windows are classified as enclosure components or partition components depending on their location, and have different design requirements, including functions such as heat insulation, sound insulation, waterproofing, and fireproofing. New requirements emphasize energy conservation; in cold regions, heat loss through gaps in doors and windows accounts for approximately 25% of total heating consumption. Therefore, the airtightness of doors and windows is a crucial aspect of energy-efficient design.

[0003] Window and door profiles play a crucial role in windows and doors. They are the basic elements that make up the window and door frames, supporting and fixing various parts of the windows and doors, and have important functions such as structural support, sealing and sound insulation, and aesthetics. However, existing windows and doors are equipped with drainage channels to prevent rainwater from seeping into the profiles during rain. But in windy weather, rainwater may affect the drainage effect under the action of the wind, making the water flow out slowly, or even backflow from the drainage channel into the profile, which has certain shortcomings. In view of this, we propose a polyurethane window and door profile. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a polyurethane door and window profile that can solve the problem that drainage channels are easily affected in windy weather.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polyurethane door and window profile, including a frame, the frame having three holes inside, the inner wall of the frame being an inclined surface, a drainage cavity inside the frame, an inclined plate fixedly connected to the inner wall of the drainage cavity, an installation groove inside the inner wall of the frame, the bottom wall of the lower installation groove being trapezoidal, a drainage hole inside the bottom wall of the lower installation groove, the lower side of the drainage hole extending into the interior of the drainage cavity, an inclined groove inside the inner wall of the drainage cavity, the rear surface of the inclined groove extending out of the rear surface of the frame, an L-shaped windbreak plate fixedly connected to the rear surface of the frame, the upper surface of the L-shaped windbreak plate being inclined.

[0006] Preferably, the inner wall of the hole is bonded with an adhesive layer, and the inner wall of the adhesive layer is bonded with sound insulation cotton.

[0007] Preferably, the sound insulation cotton has honeycomb-shaped holes.

[0008] Preferably, the inner wall of the frame is fixedly connected to two mounting plates, and mounting shafts are fixedly connected to the adjacent surfaces of the two mounting plates respectively.

[0009] Preferably, the outer surfaces of the two mounting shafts are respectively fitted with connecting sleeves, and the front surfaces of the two connecting sleeves are fixedly connected to doors and windows, with a second mounting groove provided on the front surface of the doors and windows.

[0010] Preferably, a control knob is rotatably connected to the inner wall of the second mounting groove, a threaded rod is fixedly connected to the rear surface of the control knob, and an anti-slip protrusion is fixedly connected to the outer surface of the lower mounting shaft.

[0011] Preferably, the rear end of the threaded rod rotates through the interior of the door or window, and a displacement cylinder is threaded onto the outer surface of the threaded rod.

[0012] Preferably, the rear end of the displacement cylinder slides through the rear surface of the door / window, and an arc-shaped plate is fixedly connected to the rear surface of the displacement cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) When rainwater seeps through the sealing strip and enters the installation groove during rainy weather, the trapezoidal bottom wall and drainage holes guide the rainwater into the drainage chamber. Then, the inclined plate guides the rainwater through the inclined groove to discharge. At the same time, during strong winds, the L-shaped wind deflector prevents the wind from blowing directly to the outlet of the inclined groove, reducing the wind speed at the inclined groove and thus reducing the impact of strong winds on drainage. In addition, the inclined upper surface of the L-shaped wind deflector can prevent rainwater from staying on the L-shaped wind deflector for a long time, thus avoiding problems such as rainwater corrosion and reduced service life. Through the above structure, the wind speed at the outlet of the inclined groove can be reduced during strong winds, thus avoiding the possibility of strong winds affecting drainage efficiency or even backflow, effectively improving the stability and reliability of drainage.

[0015] (2) After the polyurethane door and window profile is opened, the screw rod can be rotated by the control knob. Since the displacement cylinder slides through the rear surface of the door and window, its movement trajectory is restricted. Therefore, when the screw rod rotates, it will drive the displacement cylinder to move horizontally. Then, the displacement cylinder will drive the arc plate to move. After the arc plate moves, it contacts the installation shaft and uses anti-slip protrusions to increase friction. Through the above structure, not only can the sound insulation performance of the frame be increased, but also the arc plate and the installation shaft can be used to increase the resistance of door and window rotation, thereby avoiding the problem of forgetting to close the door and window in windy weather, causing the door and window to open and close violently and be damaged.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Please see Figure 1-5This utility model provides a technical solution: a polyurethane door and window profile, including a frame 1, with three holes 2 inside the frame 1, the inner wall of the frame 1 being an inclined surface, a drainage cavity 3 inside the frame 1, an inclined plate 4 fixedly connected to the inner wall of the drainage cavity 3, an installation groove 5 inside the inner wall of the frame 1, the bottom wall of the lower installation groove 5 being trapezoidal, a drainage hole 6 inside the bottom wall of the lower installation groove 5, the lower side of the drainage hole 6 extending into the interior of the drainage cavity 3, an inclined groove 7 inside the drainage cavity 3, the rear surface of the inclined groove 7 extending out of the rear surface of the frame 1, an L-shaped windbreak 8 fixedly connected to the rear surface of the frame 1, the upper surface of the L-shaped windbreak 8 being inclined, allowing water to penetrate the sealing strip and enter during rainy weather. When installing the interior of the groove 5, the trapezoidal bottom wall, in conjunction with the drainage hole 6, guides rainwater into the interior of the drainage chamber 3. Then, the inclined plate 4 guides the rainwater out through the inclined groove 7. At the same time, in strong winds, the L-shaped wind deflector 8 prevents the wind from blowing directly towards the outlet of the inclined groove 7, reducing the wind speed at the inclined groove 7 and thus reducing the impact of strong winds on drainage. In addition, the inclined upper surface of the L-shaped wind deflector 8 can prevent rainwater from staying on the L-shaped wind deflector 8 for a long time, thus avoiding problems such as rainwater corrosion and reduced service life. Through the above structure, the wind speed at the outlet of the inclined groove 7 can be reduced in strong winds, thus avoiding the possibility of strong winds affecting drainage efficiency or even backflow, effectively improving the stability and reliability of drainage.

[0025] Furthermore, an adhesive layer 9 is bonded to the inner wall of the hole 2, and sound insulation cotton 10 is bonded to the inner wall of the adhesive layer 9. The sound insulation cotton 10 has honeycomb-shaped holes 11. Two mounting plates 12 are fixedly connected to the inner wall of the frame 1. Mounting shafts 13 are fixedly connected to the adjacent surfaces of the two mounting plates 12. Connecting sleeves 14 are rotatably fitted onto the outer surfaces of the two mounting shafts 13. Doors and windows 15 are fixedly connected to the front surfaces of the two connecting sleeves 14. A second mounting groove 16 is formed on the front surface of the door and window 15. A control knob 17 is rotatably connected to the inner wall of the groove 16. A threaded rod 18 is fixedly connected to the rear surface of the control knob 17. An anti-slip protrusion 19 is fixedly connected to the outer surface of the lower mounting shaft 13. The rear end of the threaded rod 18 rotatably passes through the interior of the door / window 15. A displacement cylinder 20 is threadedly fitted onto the outer surface of the threaded rod 18. The rear end of the displacement cylinder 20 slides through the rear surface of the door / window 15. An arc-shaped plate 21 is fixedly connected to the rear surface of the displacement cylinder 20. The honeycomb-shaped holes 11 increase the surface area of ​​the sound insulation cotton 10. This structure enhances the material's ability to absorb sound waves. These pores allow sound waves to enter and propagate within the sound insulation cotton, increasing the chances of sound waves contacting the material surface, improving sound absorption, and breaking the material's continuity, reducing internal resonance effects and effectively reducing sound propagation. Simultaneously, after opening the door / window 15, the control knob 17 can rotate the threaded rod 18. Since the displacement cylinder 20 slides through the rear surface of the door / window 15, restricting its movement trajectory, the rotation of the threaded rod 18 synchronously drives the displacement cylinder 20 to move horizontally. This, in turn, drives the arc-shaped plate 21 to move. After moving, the arc-shaped plate 21 contacts the mounting shaft 13, and the anti-slip protrusions 19 increase friction. Through this structure, not only is the sound insulation performance of the frame 1 increased, but the arc-shaped plate 21 and mounting shaft 13 also increase the resistance to rotation of the door / window 15, preventing damage caused by forgetting to close the door / window 15 during windy weather.

[0026] Working principle: When rainwater seeps into the sealing strip and enters the installation groove 5, the trapezoidal bottom wall, in conjunction with the drainage hole 6, guides the rainwater into the drainage chamber 3. Then, the inclined plate 4 guides the rainwater through the inclined groove 7 for discharge. At the same time, in strong winds, the L-shaped wind deflector 8 prevents the wind from blowing directly towards the outlet of the inclined groove 7, reducing the wind speed at the inclined groove 7 and thus reducing the impact of strong winds on drainage. In addition, the inclined upper surface of the L-shaped wind deflector 8 can prevent rainwater from staying on the L-shaped wind deflector 8 for a long time, thus avoiding problems such as rainwater corrosion and reduced service life. After opening the door and window 15, the control knob 17 can be used to drive the threaded rod 18 to rotate. Since the displacement cylinder 20 slides through the rear surface of the door and window 15, restricting its movement trajectory, the rotation of the threaded rod 18 will simultaneously drive the displacement cylinder 20 to move horizontally. The displacement cylinder 20 then drives the arc plate 21 to move. After the arc plate 21 moves, it contacts the installation shaft 13, and the anti-slip protrusions 19 increase the friction.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
