Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a sunshade, heat insulation and energy-saving door and window. Background Technology

[0002] As the global construction industry transforms towards green and energy-saving practices, and people's demands for indoor living comfort continue to increase, doors and windows, as important building envelopes that connect buildings to the outside world, have become key indicators of building quality in terms of their energy-saving performance, shading effect, and ease of use. In the high temperatures of summer, direct sunlight entering the room through doors and windows can cause the indoor temperature to rise rapidly, increasing the operating load of the air conditioning system. In winter, if the insulation performance of doors and windows is insufficient, it will cause a large amount of heat loss from the room, increasing heating energy consumption.

[0003] Currently, there are various door and window products on the market with sunshade or heat insulation functions. Among them, some sunshade doors and windows adopt a manual sunshade curtain structure, which requires users to manually pull the sunshade curtain to open or close. The operation process is relatively cumbersome. Especially for high-rise residential buildings or large doors and windows, the convenience and safety of manual operation are poor. Moreover, manual adjustment makes it difficult to ensure the flatness and full coverage of the sunshade curtain after it is opened, which can easily lead to local light leakage and poor sunshade effect. In order to address this technical problem, this application proposes a sunshade, heat insulation and energy-saving door and window. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a sunshade, heat insulation and energy-saving door and window. Through the motor-driven screw transmission structure, combined with the guiding and limiting function of the guide rod and the sliding sleeve, the sunshade curtain can be opened and closed smoothly and automatically. It is easy to operate and can ensure that the sunshade curtain fully covers the glass body, effectively blocking direct sunlight. At the same time, the door and window adopts a double-layer low-emissivity glass design.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A sunshade, heat insulation, and energy-saving door and window includes a fixed frame, a door and window frame rotatably connected to the inner wall of the fixed frame, two glass bodies fixedly connected to the inner wall of the door and window frame, a support frame fixedly connected to the top rear end of the fixed frame, a fixed sleeve and a movable sleeve connected to the inner wall of the support frame via a driving assembly, the fixed sleeve being fixedly connected to the inner wall of the support frame, the movable sleeve being slidably connected to the inner wall of the support frame, a guide rod being fixedly connected to the inner wall of the support frame, and multiple sliding sleeves being slidably connected to the outer wall of the guide rod, with a sunshade curtain connected to the bottom end of each of the multiple sliding sleeves via a snap-fit ​​assembly.

[0006] Furthermore, the drive assembly includes a motor mounted on the inner wall of the support frame via a fixed frame. The drive end of the motor is fixedly connected to a lead screw, which is rotatably connected to the inner wall of the support frame. The left side of the outer wall of the lead screw is rotatably connected to the inner wall of the fixed sleeve, and the right side of the outer wall of the lead screw is threadedly connected to the inner wall of the movable sleeve.

[0007] Furthermore, the locking assembly includes a limiting frame located at the bottom of multiple sliding sleeves. The limiting frame is disposed on the inner wall of the sunshade. A locking rod is rotatably connected to the rear end of the limiting frame. A tenon is fixedly connected to the inner circumference of the locking rod. The tenon is disposed in a slot opened on the outer wall of the limiting frame.

[0008] Furthermore, the top end of the leftmost sliding sleeve is fixedly connected to the bottom end of the movable sleeve, and the top end of the rightmost sliding sleeve is fixedly connected to the bottom end of the fixed sleeve.

[0009] Furthermore, the left sides of both the front and rear ends of the door and window frame are connected to the fixed frame via handles.

[0010] Furthermore, an adhesive strip is fixedly connected to the inner circumference of the fixed frame, and the adhesive strip is located at the rear end of the door and window frame.

[0011] Furthermore, both glass bodies are low-emissivity glass.

[0012] Furthermore, the cavity formed between the two glass bodies is filled with argon gas.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the screw transmission structure driven by the motor, combined with the guiding and limiting function of the guide rod and the sliding sleeve, enables the smooth and automatic opening and closing of the sunshade curtain. It is easy to operate and ensures that the sunshade curtain fully covers the glass body, effectively blocking direct sunlight. At the same time, the door and window adopt a double-layer low-emissivity glass design, and the cavity formed by the two layers of glass is filled with argon gas. The low-emissivity glass can reflect outdoor infrared rays, and the low thermal conductivity of argon gas further reduces the heat conduction between the glass layers. The two work together to greatly improve the heat insulation and energy-saving performance of the door and window, reduce the heat exchange between indoor and outdoor environments, reduce the energy consumption of building air conditioning or heating, and improve the comfort of indoor living.

[0014] 2. In this utility model, the locking assembly of the tenon block and the locking rod can complete the connection and fixation of the sunshade and the sliding sleeve without the need for additional fasteners. The sunshade can be quickly disassembled for cleaning and maintenance simply by bending the locking rod to disengage the tenon block from the limiting bracket slot. The operation is simple and maintenance is convenient. In addition, the rubber strip fixed on the inner circumference of the fixed frame can effectively fill the gap between the door and window frame and the fixed frame, reduce indoor and outdoor air convection, not only help to improve the heat insulation effect, but also reduce the degree of outdoor noise entering the room. At the same time, it buffers the impact force when the door and window frame is closed, reduces component wear, and extends the overall service life of the door and window.

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.

[0018] Reference Figures 1-3 An embodiment of this utility model provides a sunshade, heat insulation, and energy-saving door and window, including a fixed frame 1, a door and window frame 2 rotatably connected to the inner wall of the fixed frame 1, two glass bodies 4 fixedly connected to the inner wall of the door and window frame 2, a support frame 6 fixedly connected to the top side of the rear end of the fixed frame 1, a fixed sleeve 9 and a movable sleeve 10 connected to the inner wall of the support frame 6 through a motor 8 and a lead screw 7, the fixed sleeve 9 fixedly connected to the inner wall of the support frame 6, the movable sleeve 10 slidably connected to the inner wall of the support frame 6, a guide rod 15 fixedly connected to the inner wall of the support frame 6, a plurality of sliding sleeves 11 slidably connected to the outer wall of the guide rod 15, and a sunshade curtain 16 connected to the bottom end of each of the plurality of sliding sleeves 11 through a limiting frame 12, a locking rod 13 and a tenon block 14; Specifically, the fixed frame 1 serves as the basic load-bearing structure of the entire door and window, providing a stable installation benchmark for components such as the door and window frame 2 and the support frame 6 to ensure overall stability. The door and window frame 2 achieves opening and closing of the door and window through a rotating connection with the fixed frame 1. The two glass bodies 4 fixed on its inner wall are the core of light transmission and heat insulation. The support frame 6 is fixed to the top rear end of the fixed frame 1, serving as the installation carrier for the sunshade mechanism. It provides support space for components such as the motor 8, lead screw 7, and guide rod 15 without occupying effective indoor or outdoor space. In the drive assembly, the motor 8, as the power source, is installed on the inner wall of the support frame 6 through the fixed frame to ensure stable operation. The lead screw 7, as a transmission component, is rotatably connected to the fixed sleeve 9 on the left and the screw on the right. The sliding sleeve 11 is connected to the movable sleeve 10, and the guide rod 15 is fixed to the inner wall of the support frame 6. It guides the movement of the sliding sleeve 11 and prevents the sliding sleeve 11 from shifting or jamming when it drives the sunshade 16. The leftmost sliding sleeve 11 is connected to the movable sleeve 10, and the rightmost sliding sleeve 11 is connected to the fixed sleeve 9. The sliding sleeve 11 can be moved synchronously by the sliding sleeve 10, thereby realizing the opening and closing of the sunshade 16. In the locking assembly, the limiting frame 12 is fitted on the inner wall of the sunshade 16 to connect and fix the sunshade 16 and the sliding sleeve 11. The locking rod 13 cooperates with the tenon 14. The limiting frame 12 is closed and opened by the tenon 14 being inserted into the slot of the limiting frame 12, thereby fixing or removing the sunshade 16.

[0019] Reference Figures 4-6 The motor 8, mounted on the inner wall of the support frame 6 via a fixed bracket, has a lead screw 7 fixedly connected to its drive end. The lead screw 7 is rotatably connected to the inner wall of the support frame 6, and its outer left side is rotatably connected to the inner wall of the fixed sleeve 9. Its outer right side is threadedly connected to the inner wall of the movable sleeve 10. A limiting frame 12, located at the bottom of multiple sliding sleeves 11, is set on the inner wall of the sunshade curtain 16. A locking rod 13 is rotatably connected to the rear end of the limiting frame 12, and a locking rod 13 is fixedly connected to its inner circumference. Tenon 14 is set in the slot opened on the outer wall of the limiting frame 12. The top of the leftmost sliding sleeve 11 is fixedly connected to the bottom of the moving sleeve 10, and the top of the rightmost sliding sleeve 11 is fixedly connected to the bottom of the fixed sleeve 9. The left sides of both the front and rear ends of the door and window frame 2 are connected to the fixed frame 1 through the handle 3. The inner circumference of the fixed frame 1 is fixedly connected with the adhesive strip 5, which is set at the rear end of the door and window frame 2. Both glass bodies 4 are low-emissivity glass, and the cavity formed between the two glass bodies 4 is filled with argon gas. Specifically, handles 3 are installed on the left side of both the front and rear ends of the door and window frame 2, allowing users to easily open and close the doors and windows from both inside and outside without the need for additional tools, thus improving ease of use. The adhesive strip 5 is fixed to the inner circumference of the fixed frame 1 and located at the rear end of the door and window frame 2. It fills the gap between the door and window frame 2 and the fixed frame 1, reducing indoor and outdoor air convection to enhance heat insulation. It also improves sound insulation and cushions the impact force when the door and window frame 2 is closed, extending the lifespan of the doors and windows. Both glass bodies 4 are low-emissivity glass, which reflects outdoor infrared rays to reduce heat entering the room in summer without affecting visible light transmission, thus balancing heat insulation and lighting. The cavity between them is filled with argon gas. Argon gas has a much lower thermal conductivity than air, which can further reduce the heat conduction efficiency of the glass to enhance the heat insulation and energy-saving effect. The tenon block 14 and the slot of the limiting frame 12 adopt a tenon and mortise type fit. The structure is simple and the connection is firm. No screws or other fasteners are required. When disassembling, only the lever 13 needs to be pried to make the tenon block 14 disengage from the slot, which is convenient for cleaning and replacing the sunshade curtain 16. The rotational connection between the screw rod 7 and the support frame 6, and the sliding connection between the moving sleeve 10 and the support frame 6, all adopt a smooth fit structure to reduce the frictional resistance between the parts and ensure that the sunshade curtain 16 unfolds or closes smoothly when driven by the motor 8, avoiding jamming or abnormal noise.

[0020] Working principle: When sunshade 16 is needed, the motor 8, which is mounted on the inner wall of the support frame 6 via a fixed frame, is activated. The lead screw 7, which is fixedly connected to the drive end of the motor 8, rotates accordingly. Since the left side of the lead screw 7 is rotatably connected to the fixed sleeve 9 fixed to the inner wall of the support frame 6, the lead screw 7 rotates stably without deviating. The movable sleeve 10, which is threaded to its right side, slides along the inner wall of the support frame 6 under the action of the rotation of the lead screw 7. The leftmost sliding sleeve 11, which is fixed at the bottom end of the movable sleeve 10, moves synchronously. All sliding sleeves 11 are slidably connected to the outer wall of the guide rod 15 fixed to the inner wall of the support frame 6. Under the guidance and limitation of the guide rod 15, the sliding sleeves 11 drive the sunshade 16, which is connected at the bottom end via a snap-fit ​​assembly, to unfold smoothly from right to left, finally covering the sunshade 16. The entire glass body 4 is fixed to the inner wall of the door and window frame 2. Conversely, if the sunshade 16 needs to be retracted, the motor 8 is started to make the lead screw 7 rotate in the opposite direction, driving the moving sleeve 10 to slide from left to right, and then driving the sunshade 16 to retract through the sliding sleeve 11. When the sunshade 16 needs to be cleaned after a period of use, the locking rod 13 connected to the rear end of the limiting frame 12 is turned to make the tenon 14 fixed on the inner circumference of the locking rod 13 disengage from the slot opened on the outer wall of the limiting frame 12, and the limiting frame 12 forms a notch, so the sunshade 16 fitted on the inner wall of the limiting frame 12 can be removed for cleaning. After cleaning, the sunshade 16 is put back on the limiting frame 12, and the locking rod 13 is rotated to make the tenon 14 engage in the slot of the limiting frame 12, so that the sunshade 16 can be fixed to prevent it from falling off.

[0021] It is worth noting that the circuits involved in the above embodiments all adopt corresponding existing technologies according to the actual situation, so they will not be described in detail in the embodiments of this application.

[0022] 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.
