Technical Field

[0001] This utility model relates to the field of door and window accessories technology, specifically, a quick-release and assembly structure for door and window hinges. Background Technology

[0002] Door and window hinges are accessories used to connect window frames and window sashes. Traditionally, door and window connections typically use multiple screws to fasten the hinges to the window frame or sash. When it's necessary to remove the screen for cleaning or replacement, the screws must be removed, a cumbersome and time-consuming process. Repeated disassembly and reassembly can easily lead to stripped screws or frame damage, affecting structural stability and lifespan. Furthermore, in the past, casement screens were directly installed using hinges. During installation, the operator needed one hand to hold the window sash and the other to position it. Disassembly required removing the screen sash and hinges from the window frame as a whole, and then removing the hinges from the screen sash, all with the aid of tools, making both disassembly and reassembly inconvenient.

Detailed Implementation

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] It should be understood that the door leaf includes an upper profile, a lower profile, and side profiles for connecting to the window frame. All three profiles have profile grooves, which are T-shaped. These are all existing structural elements and are not shown in the attached diagram. Please refer to existing casement window structures for details.

[0018] like Figures 1 to 6The diagram shows a quick-release hinge structure for doors and windows, including a base assembly 1 and a plug-in assembly 2. The base assembly 1 is provided with a first hook 3 that protrudes upwards. The plug-in assembly 2 is provided with a snap-fit ​​piece 4. The lower end of the snap-fit ​​piece 4 is provided with a second hook 5 that hooks with the first hook 3. One side of the upper end of the snap-fit ​​piece 4 extends out of the plug-in assembly 2, and the other side of the snap-fit ​​piece 4 abuts against a spring 6. A post 7 passes through the snap-fit ​​piece 4, and the snap-fit ​​piece 4 can rotate around the post 7. The plug-in assembly 2 is directly inserted into the profile groove on one side of the window sash, and the base assembly 1 is inserted into the profile grooves at the upper and lower ends of the window sash. The bottom surface of the base assembly 1 is connected to a hinge, and the other end of the hinge is connected to the window frame. During installation, place the first hook 3 on the base assembly 1 facing upwards, and position the second hook 5 on the plug-in assembly 2 towards the first hook 3. Simultaneously press the latching piece 4 extending from one side of the plug-in assembly 2. The latching piece 4 rotates around the column 7 until the second hook 5 at the lower end of the latching piece 4 is horizontally aligned with the first hook 3. Then, release the latching piece 4. The other side of the upper end of the latching piece 4 returns to its original position under the action of a spring, and the second hook 5 and the first hook 3 are hooked together. By hooking the second hook 5 in the plug-in assembly 2 with the first hook 3 on the base assembly 1, the window sash is connected to the hinge, thereby achieving the installation connection between the window sash and the window frame. No screws or bolts need to be installed on the window sash. Simply press the latching piece 4 on one side of the plug-in assembly 2 for quick assembly and disassembly, simplifying the operation steps and avoiding problems such as stripped screws and frame wear caused by repeated assembly and disassembly. At the same time, it reduces the number of parts, lowers processing and maintenance costs, and extends the overall service life. The built-in hook structure makes the quick assembly and disassembly structure appear as a single unit, simple and less prone to accidental activation.

[0019] Specifically, in this embodiment, the plug-in component 2 has a first groove 8 on one side, and one side of the upper end of the snap-fit ​​piece 4 extends out of the first groove 8. The plug-in component 2 has a second groove 9 on the other side opposite to the first groove 8. The first groove 8 is used to accommodate the snap-fit ​​piece 4, facilitating finger insertion and pressing. The second groove 9 is located on the other side of the plug-in component 2 opposite to the first groove 8. Since the plug-in component 2 itself is a small part, two fingers can be placed opposite each other to press firmly, which is more ergonomic. The width of the second groove 9 can be the same as or greater than the width of the first groove 8. When the width of the second groove 9 is greater than the width of the first groove 8, the snap-fit ​​piece 4 is less likely to come out through the second groove 9, and the plug-in component 2 is seamlessly integrated on one side of the second groove 9, resulting in better integrity.

[0020] The plug-in assembly 2 of this embodiment includes a housing 10 and a cover plate 11, which are connected by a snap-fit ​​part 12. A reinforcing rib 13 is provided inside the housing 10, and a column 7 protrudes from the reinforcing rib 13. The snap-fit ​​part 12 facilitates the disassembly of the plug-in assembly 2, allowing for easy maintenance or replacement of the spring 6 or the snap-fit ​​piece 4 inside the assembly 2. The reinforcing rib 13 improves the overall structural strength and rigidity of the plug-in assembly 2. The column 7 protrudes from the reinforcing rib 13, causing the snap-fit ​​piece 4 to be located on the upper surface of the reinforcing rib 13. Pressing one side of the snap-fit ​​piece 4 causes it to rotate around the column 7 on the surface of the reinforcing rib 13.

[0021] Specifically, in this embodiment, a snap-fit ​​groove 14 is formed on the side of the housing 10 away from the cover plate 11. The side wall of the snap-fit ​​groove 14 that fits with the window sash is provided with an arc-shaped protrusion 15. The snap-fit ​​groove 14 is inserted into the profile groove of the window sash, so that the back of the insertion component 2 is connected to the window sash. At the same time, the side wall of the snap-fit ​​groove 14 after it fits with the profile groove is provided with an arc-shaped protrusion 15, so that the outer wall of the housing 10 fits more tightly with the inner wall of the profile groove. Multiple arc-shaped protrusions 15 can be symmetrically arranged.

[0022] The base assembly 1 in this embodiment includes a first connecting plate 16 and a second connecting plate 17, which are fixedly connected. The first hook 3 is integrally bent to one end of the first connecting plate 16. The base assembly 1 is designed as a double-layer structure, which has stronger overall load-bearing capacity and higher stability. The first hook 3 and the first connecting plate 16 are an integral structure, which avoids the disadvantages of weak welding points or screw connections in traditional split structures, reduces the risk of breakage, and makes the connection between the plug-in assembly 2 and the base assembly 1 more stable.

[0023] Preferably, in this embodiment, the second connecting plate 17 has an upwardly folding tab 18, and the first connecting plate 16 has an insertion slot 19 corresponding to the tab. The tab 18 passes through the insertion slot 19 and then bends away from the first hook 3. The tab 18 is directly integrally formed from the second connecting plate 17 and folds upward. After passing through the insertion slot 19 on the first connecting plate 16, it wraps around the first connecting plate 16 away from the first hook 3, connecting the first connecting plate 16 and the second connecting plate 17 together. During use, the first connecting plate 16 is not easily detached from the second connecting plate 17.

[0024] It is worth noting that in this embodiment, the first connecting plate 16 and the second connecting plate 17 are fixedly connected at their centers by rivets 20; the rivets 20 make the connection between the first connecting plate 16 and the second connecting plate 17 more stable.

[0025] Preferably, in this embodiment, a plurality of limiting portions 21 are provided between the first connecting plate 16 and the second connecting plate 17, forming a slot structure between the first connecting plate (16) and the second connecting plate (17); the limiting portion 21 forms a slot structure with the first connecting plate 16 and the second connecting plate 17, and this slot structure can limit the profile groove that is inserted into the base assembly 1, preventing the window sash from swaying left and right. The limiting portion 21 can be a downward concave portion formed by directly stamping the first connecting plate 16, or an upward convex portion formed by directly stamping the second connecting plate 17, or a structure that is additionally welded between the first connecting plate 16 and the second connecting plate 17.

[0026] In this embodiment, a flange 22 is formed at one end of the first connecting plate 16 near the first hook 3; when the base assembly 1 is inserted into the profile groove of the window sash, the flange 22 abuts against the profile, further preventing the base assembly 1 from falling out of the profile groove.
