Description

Technical Field

[0001] This utility model belongs to the field of door and window technology, specifically relating to an adjustable door and window gap. Background Technology

[0002] Doors and windows are an important part of the building envelope, with functions such as wind and rain protection, heat insulation, sound insulation, and lighting. They must meet the requirements of lighting, ventilation, dust prevention, and theft prevention, and be in harmony with architectural aesthetics and the environment.

[0003] Adjustable door and window gaps are devices that allow for adjustable gap sizes through a specific structure. They are mainly used to improve the shortcomings of traditional doors and windows, which cannot adjust the gap width according to actual needs, thereby enhancing sealing and flexibility of use. These types of doors and windows are suitable for scenarios that require flexible control of ventilation, such as kitchens, bathrooms and other areas with high requirements for sealing, or places that need to take into account the function of preventing mosquitoes and insects.

[0004] Traditional doors and windows typically have a fixed opening angle, usually only able to be fixed to the maximum or minimum angle. The middle position is usually not possible to position, and the gap size cannot be flexibly adjusted according to the needs of ventilation, sun shading, rain protection, etc., resulting in low adjustment accuracy and unreliable fixing. Utility Model Content

[0005] To address the issues raised in the background art, where the opening angle of traditional doors and windows is typically fixed, generally only able to be fixed to either the maximum or minimum angle, and the intermediate position is usually unavailable, this invention provides an adjustable door / window with adjustable gaps. This prevents flexible adjustment of the gap size according to needs such as ventilation, sun shading, and rain protection, resulting in low adjustment precision and unreliable fixing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable door and window gap, comprising a base, a frame, and a window frame, wherein the base and the frame are fixedly connected to form an installation frame, a positioning rod is fixedly connected to the inner side of the frame, and the window frame is rotatably connected to the inner side of the positioning rod via a positioning shaft;

[0007] A guide groove is provided at the connection between the base and the window frame. A linkage block is fixedly connected to one side of the bottom of the window frame. A limit groove is provided at the connection between the linkage block and the base. Several positioning holes are connected below the limit groove. A positioning pin is inserted inside the linkage block.

[0008] As a preferred embodiment of the adjustable door and window gap of this utility model, the window frame is fixedly installed with hollow tempered glass.

[0009] As a preferred embodiment of the adjustable door and window gap of this utility model, the guide groove has a T-shaped cross section, the bottom of the window frame is provided with a matching T-shaped protrusion, and the bottom of the window frame is slidably fitted into the guide groove.

[0010] As a preferred embodiment of the adjustable door and window gap of this utility model, the linkage block is inserted into the limiting groove to form a sliding pair, and a scale line is provided on one side of the limiting groove, and the scale line corresponds one-to-one with the position of the positioning hole.

[0011] As a preferred embodiment of the adjustable door and window gap of this utility model, the positioning pin can be inserted and removed through the linkage block and the positioning hole, and the positioning holes are evenly distributed.

[0012] As a preferred embodiment of the adjustable door and window gap of this utility model, the rear end of the base extends to form a windowsill, a storage groove is opened on the windowsill, and a through-hole filter hole is opened at the bottom of the storage groove.

[0013] As a preferred embodiment of the adjustable door and window gap of this utility model, the water filter holes are inclined and equidistantly distributed.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This application achieves multi-level opening precision by using multi-level positioning holes in conjunction with scale lines to meet the differentiated needs of ventilation / sunshade / rainproof. The guide groove and linkage block form a double-track constraint to eliminate window frame swaying. The positioning pin is locked through the entire base, and the force is borne by the entire base to avoid local deformation. The mechanical pin lock resists wind pressure and has no risk of slippage, preventing the problem that the opening angle of traditional doors and windows is usually fixed and the middle position is usually impossible to position.

[0021] 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. Embodiment 1

[0022] like Figures 1-4 As shown;

[0023] An adjustable door and window gap includes a base 1, a frame 2, and a window frame 5. The base 1 and the frame 2 are fixedly connected to form an installation frame. A positioning rod 3 is fixedly connected to the inner side of the frame 2. The window frame 5 is rotatably connected to the inner side of the positioning rod 3 through a positioning shaft 4. A guide groove 10 is provided at the connection between the base 1 and the window frame 5. A linkage block 6 is fixedly connected to one side of the bottom of the window frame 5. A limit groove 8 is provided at the connection between the linkage block 6 and the base 1. Several positioning holes 9 are connected below the limit groove 8. A positioning pin 7 passes through the linkage block 6.

[0024] In this implementation plan: multi-level positioning holes 9 are used in conjunction with scale lines to achieve multi-level opening precision, meeting the differentiated needs of ventilation / sunshade / rain protection. The guide groove 10 and the linkage block 6 form a double-track constraint to eliminate the swing of the window frame 5. The positioning pin 7 is locked through the entire structure. The force is borne by the base 1 as a whole to avoid local deformation. The mechanical pin lock is wind pressure resistant and has no risk of slippage.

[0025] In an optional embodiment, a double-glazed tempered glass 11 is fixedly installed inside the window frame 5.

[0026] In this implementation plan, the scale lines and the positioning holes 9 are precisely aligned, allowing the operator to intuitively identify the door and window opening angles, such as 30° and 45°, without the need for repeated trial and error, greatly improving adjustment efficiency. At the same time, it avoids the risk of misalignment of the positioning pins 7 due to visual error, enhancing the reliability of the adjustment process.

[0027] In an optional embodiment, the guide groove 10 has a T-shaped cross section, and the bottom of the window frame 5 is provided with a matching T-shaped protrusion, with the bottom of the window frame 5 being slidably fitted into the guide groove 10.

[0028] In this implementation plan: the T-shaped protrusion and the cross-section of the guide groove 10 are matched to form a three-dimensional constraint, which prevents the window frame 5 from swaying left and right, avoids the window frame 5 from being lifted and detached, and significantly improves the stability of the opening and closing process of the door and window, especially reducing abnormal noise and vibration under strong wind conditions.

[0029] In an optional embodiment, the linkage block 6 is inserted into the limiting groove 8 to form a sliding pair. The limiting groove 8 has a scale line on one side, and the scale line corresponds one-to-one with the position of the positioning hole 9.

[0030] In this implementation scheme: the clearance fit between the linkage block 6 and the limiting groove 8 ensures that the motion trajectory is strictly linear, and the scale line is set on the side wall of the limiting groove 8 so that the observation angle is coaxial with the positioning hole 9, eliminating visual parallax and further improving the accuracy of angle reading.

[0031] In an optional embodiment, the positioning pin 7 is pluggable through the linkage block 6 and the positioning hole 9, which are equidistantly distributed.

[0032] In this implementation plan: the equidistantly distributed positioning holes 9 enable proportional adjustment of the opening angle to meet standardized ventilation requirements, and the through-hole insertion and removal design of the positioning pins 7 provides mechanical hard locking, which improves wind pressure resistance compared to friction limiting methods.

[0033] In an optional embodiment, the rear end of the base 1 extends to form a windowsill 12, and a storage slot 13 is opened on the windowsill 12. A through water filter hole 14 is opened at the bottom of the storage slot 13. The water filter hole 14 is inclined and is evenly distributed between the water filter holes 14.

[0034] In this implementation plan: the integrated design of the platform 12 and the base 1 enhances the overall structural integrity; the storage trough 13 provides a dedicated placement area for plants / items; the water filter holes 14 enable active drainage, preventing rainwater accumulation and corrosion of the windowsill, and extending service life; the inclined structure of the water filter holes 14, together with the inclined bottom surface of the storage trough 13, forms a directional flow channel, accelerating drainage efficiency; the equidistant distribution ensures that there are no dead corners for water accumulation in the trough.

[0035] Working principle: First, fix the base 1 and frame 2 to the reserved position on the wall to complete the installation of the door and window. During the rotation and opening process, the window frame 5 forms a rotating pair with the positioning rod 3 on the base 1 through the positioning shaft 4 at the bottom, so that the door and window can rotate around the axis. The bottom of the window frame 5 is embedded in the guide groove 10 to ensure the movement trajectory. During the rotation and opening process, the linkage block 6 on the side wall of the window frame 5 is inserted into the limiting groove 8 and slides synchronously.

[0036] The limiting groove 8 is provided with equidistantly distributed positioning holes 9, corresponding to different opening angles such as 15°, 30°, and 45°. Lifting the positioning pin 7 upwards pushes the window frame 5 to the target angle, and the linkage block 6 reaches directly below the corresponding positioning hole 9. Then, pressing the positioning pin 7 downwards penetrates the linkage block 6 and the positioning hole 9 to achieve mechanical hard locking. At the same time, the side wall of the limiting groove 8 is marked with scale lines, which are aligned with the position of the positioning hole 9, so that the user can intuitively select the opening size.

[0037] The double-glazed tempered glass 11 ensures heat insulation and sound insulation, while the windowsill 12 integrates a storage groove 13 and a water filter hole 14. The bottom of the groove is inclined and has a water filter hole 14. Rainwater or irrigation water seepage is discharged through the water filter hole 14 to avoid water accumulation in the green plants. It takes into account both the placement of green plants and automatic drainage, thus improving practicality.

[0038] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
