Description

Technical Field

[0001] This utility model belongs to the field of energy-saving doors and windows technology, specifically relating to a sunshade, heat insulation and energy-saving door and window. Background Technology

[0002] Energy-saving windows and doors differ from our common understanding of saving electricity. They refer to windows and doors designed to increase natural light and ventilation or to showcase the characteristics of modern architecture. They possess the following features: First, energy-saving windows and doors improve the optical, thermal, and sealing properties of materials to enhance their construction. This includes measures such as double-glazed or multi-layered glass, internal and external shading systems, controlling the window-to-wall ratio in different orientations, and adding insulated curtains to achieve the desired effect. Second, energy-saving windows and doors are made from various materials, including high-tech energy-saving products such as aluminum alloy thermally broken profiles, aluminum-wood composite profiles, steel-plastic integrated extruded profiles, and UPVC plastic profiles.

[0003] Existing doors and windows generally have poor overall sunshade and heat insulation performance, especially when faced with intense heat during hot weather, their ability to regulate indoor temperature is quite limited. These doors and windows often fail to effectively block the intrusion of external heat, resulting in persistently high indoor temperatures and causing discomfort to residents. Therefore, a sunshade, heat insulation, and energy-saving door or window is needed to help solve this problem. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sunshade, heat insulation and energy-saving door and window. When the outside heat is high, the sunshade, heat insulation and energy-saving door and window can effectively improve the overall sunshade and heat insulation effect of the door and window by providing auxiliary sunshade to the door and window body. At the same time, the connecting plate drives the sunshade pad to be pulled as a whole, which can prevent the sunshade pad from being blown up excessively when encountering airflow.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a sunshade, heat insulation and energy-saving door and window, which includes a window frame, an installation cavity on the window frame, a blocking strip vertically fixed in the installation cavity, a door and window body installed in the installation cavity by hinges, a sunshade component installed at the front end of the window frame, and a U-shaped fixing frame fixed on the window frame corresponding to the sunshade component.

[0008] The sunshade assembly includes a fixing box fixed to the window frame, an internal cavity for receiving, a rotatable winding rod inside the cavity, a sunshade pad wound on the winding rod, a conveying cavity on the inner side of the fixing frame, a rotatable lead screw inside the conveying cavity, a connecting plate sleeved on the lead screw, one end of the sunshade pad fixed to the top of the connecting plate, and a transmission assembly for driving the lead screw to rotate at the bottom of the fixing frame.

[0009] Furthermore, a rotating disc is fixedly fitted at both ends of the sunshade pad, and a reset cavity is opened at both ends of the fixing box, with a torsion spring for assisting the rotation of the winding rod installed in the reset cavity.

[0010] Furthermore, the transmission assembly includes a transmission wheel sleeved and fixed at the bottom of the lead screw, a transmission belt connecting the two transmission wheels, and a transmission motor that drives the transmission wheels to rotate fixed at the bottom of the fixed frame.

[0011] Furthermore, the surface of the sunshade pad is coated with a water-based sunshade paint.

[0012] Furthermore, positioning holes are provided on both sides of the blocking strip, and a fixing component is installed in the middle section of the side of the door and window body away from the door and window body, and the positioning holes and the fixing component are fixed together.

[0013] Furthermore, the fixing component includes a hinge seat fixed to the door / window body by fixing bolts, a handle is hingedly installed on the hinge seat, a positioning cavity is opened inside the door / window body, a pin is slidably disposed in the positioning cavity, a top pressure spring for assisting the pin to push is installed in the positioning cavity, and the pin and the handle are connected and fixed by a connecting strap.

[0014] Furthermore, a grooved wheel is rotatably provided inside the door / window body, and the connecting belt is wrapped around and installed on the outer edge of the grooved wheel.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes the cooperation between a sunshade component and a fixed frame located on the outer side of the window frame. Activating the drive motor causes the drive wheel to rotate, which in turn rotates the drive belt and both drive wheels, causing the lead screw to rotate. The threaded connection between the connecting plate and the lead screw lowers the connecting plate, pulling the sunshade pad and causing the winding rod to rotate and the torsion spring to coil. The lowering of the sunshade pad provides auxiliary sunshade and heat insulation for the window / door body. When the connecting plate rises, the compressed torsion spring rotates the winding rod, retracting the sunshade pad. This design effectively improves the overall sunshade and heat insulation of the window / door when there is high external heat by providing auxiliary sunshade. Furthermore, the pulling motion of the sunshade pad by the connecting plate prevents it from being excessively blown up by airflow.

[0018] This utility model utilizes the cooperation between the positioning holes and fixing components on the blocking strip. Pulling the handle moves the connecting belt, which in turn pulls and retracts the latch, compressing the top pressure spring and closing the door / window body. After the door / window body is closed, releasing the handle causes the compressed top pressure spring to move the latch and insert it into the positioning hole, thus completing the overall positioning and fastening of the door / window body. This ensures that the door / window body can be stably and securely fixed in the corresponding position during operation. Attached Figure Description

[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 protection scope of the present utility model.

[0026] This specific embodiment is a sunshade, heat insulation, and energy-saving door and window, such as Figure 1 , Figure 2 and Figure 3 As shown, the sunshade, heat insulation, and energy-saving door and window includes a window frame 1. An installation cavity is provided on the window frame 1, and a blocking strip 4 is vertically fixed inside the installation cavity. The door and window body 2 is hinged inside the installation cavity via a hinge 3. A sunshade component 13 is installed at the front end of the window frame 1. A U-shaped fixing frame 14 is fixed to the window frame 1 corresponding to the sunshade component 13. The sunshade component 13 includes a fixing box 131 fixed to the window frame 1. An accommodating cavity is provided inside the fixing box 131, and a winding rod 15 is rotatably mounted inside the accommodating cavity. Rotating discs 151 are fixed to both ends of the sunshade pad 16. Reset cavities are provided at both ends of the fixing box 131, and torsion blocks for assisting the rotation of the winding rod 15 are installed in the reset cavities. A sunshade pad 16 is wound and installed on a spring 152 and a winding rod 15. The surface of the sunshade pad 16 is sprayed with water-based sunshade paint. A conveying cavity is opened on the inner side of the fixing frame 14. A lead screw 18 is rotatably installed in the conveying cavity. A connecting plate 17 is sleeved on the lead screw 18. One end of the sunshade pad 16 is fixed to the top of the connecting plate 17. A transmission assembly 19 that drives the lead screw 18 to rotate is installed at the bottom of the fixing frame 14. The transmission assembly 19 includes a transmission wheel 22 that is sleeved and fixed at the bottom of the lead screw 18. A transmission belt 21 is provided between the two transmission wheels 22. A transmission motor 20 that drives the transmission wheel 22 to rotate is fixed at the bottom of the fixing frame 14.

[0027] Through the cooperation between the sunshade assembly 13 and the fixed frame 14 on the outer side of the window frame 1, the drive motor 20 is started. The drive motor 20 drives the drive wheel 22 to rotate as a whole. When the drive wheel 22 rotates, it drives the drive belt 21 to rotate as a whole and makes the two drive wheels 22 rotate as a whole, thereby causing the lead screw 18 to rotate as a whole. The connecting plate 17 is threadedly engaged with the lead screw 18, thereby causing the connecting plate 17 to descend as a whole. When the connecting plate 17 descends, it pulls the sunshade pad 16, thereby causing the winding rod 15 to rotate as a whole and the torsion spring 152 to be wound and contracted. By lowering the sunshade pad 16 as a whole, the door and window body 2 is provided with auxiliary sunshade and heat insulation treatment. When the connecting plate 17 rises, the compressed torsion spring 152 drives the winding rod 15 to rotate as a whole, thereby realizing the overall winding treatment of the sunshade pad 16. When the external heat is high, the door and window body 2 can be assisted in sunshade, thereby effectively improving the overall sunshade and heat insulation effect of the door and window. At the same time, the connecting plate 17 pulls the sunshade pad 16 as a whole, which can prevent the sunshade pad 16 from being blown up excessively when encountering airflow.

[0028] Search Figure 1 and Figure 4 As shown, positioning holes are provided on both sides of the blocking strip 4. A fixing component 5 is installed in the middle section of the side of the door and window body 2 away from the door and window body 2. The positioning holes and the fixing component 5 are fixed together. The fixing component 5 includes a hinge seat 6 fixed to the door and window body 2 by fixing bolts 7. A handle 8 is hingedly installed on the hinge seat 6. A positioning cavity is provided inside the door and window body 2. A pin 10 is slidably arranged in the positioning cavity. A top pressure spring 11 is installed in the positioning cavity to assist the pin 10 in pushing. The pin 10 and the handle 8 are connected and fixed by a connecting strap 9. A grooved wheel 12 is rotatably arranged inside the door and window body 2. The connecting strap 9 is wrapped around the outer edge of the grooved wheel 12.

[0029] By cooperating with the positioning holes on the blocking strip 4 and the fixing components 5, the handle 8 is pulled, and the handle 8 drives the connecting belt 9 to move as a whole. When the connecting belt 9 moves, the pin 10 is pulled and retracted, thereby compressing the top pressure spring 11 and closing the door and window body 2 as a whole. After the door and window body 2 is closed, the handle 8 is released, and the compressed top pressure spring 11 drives the pin 10 to move as a whole and insert into the positioning hole, thereby completing the overall positioning and fastening of the door and window body 2. This ensures that the door and window body 2 can be stably pulled and fixed in the corresponding position during operation.

[0030] Working principle:

[0031] During operation, before closing the door / window body 2, pull the handle 8. The handle 8 moves the connecting belt 9 as a whole. As the connecting belt 9 moves, the latch 10 is pulled and retracted, thereby compressing the top pressure spring 11 and closing the door / window body 2 as a whole. After the door / window body 2 is closed, release the handle 8. The compressed top pressure spring 11 moves the latch 10 as a whole and inserts it into the positioning hole, thus completing the overall positioning and fastening of the door / window body 2.

[0032] The drive motor 20 is started, which drives the drive wheel 22 to rotate as a whole. When the drive wheel 22 rotates, it drives the drive belt 21 to rotate as a whole and makes both drive wheels 22 rotate as a whole, thereby causing the lead screw 18 to rotate as a whole. The connecting plate 17 is threadedly engaged with the lead screw 18, thereby causing the connecting plate 17 to descend as a whole. When the connecting plate 17 descends, it pulls the sunshade pad 16, thereby causing the winding rod 15 to rotate as a whole and the torsion spring 152 to be wound and contracted. As the sunshade pad 16 descends as a whole, it provides auxiliary shading and heat insulation treatment for the door and window body 2. When the connecting plate 17 rises, the compressed torsion spring 152 drives the winding rod 15 to rotate as a whole, thereby realizing the overall winding treatment of the sunshade pad 16.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
