Abstract
Description
Technical Field
[0001] This utility model belongs to the field of door and window technology, and relates to a quick-installation structure for door or window frames. Background Technology
[0002] Doors and windows are essential components of modern architecture. Currently, most door and window frames are welded or assembled from metal materials such as aluminum alloy. For example, a flush-mount door frame disclosed in Chinese patent application (application number: 202420718923.X) includes two longitudinal MDF boards, two transverse MDF boards, a door panel, and four connectors. All MDF boards are isosceles trapezoidal in shape, and the sloping top of the longitudinal MDF boards is connected to the sloping sides of the bottom transverse MDF boards via connectors. Although this flush-mount door frame has a simple structure and is not complicated to assemble, its installation requires aligning the sloping sides of the MDF boards to be connected before inserting the connectors from the side. During installation, the installer needs to exert force to maintain alignment between the two MDF boards, making the operation difficult and the installation efficiency low. Furthermore, the MDF boards are only fixed together by connectors made of wooden dowels, resulting in low connection strength and poor stability, which can easily lead to loosening and disintegration over time. Summary of the Invention
[0003] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a quick-installation structure for door or window frames. The technical problem this utility model aims to solve is: how to make the installation of door or window frames simpler and faster.
[0004] The purpose of this utility model can be achieved through the following technical solution: a quick-installation structure for a door frame or window frame, the door frame or window frame including a plurality of elongated frame strips; characterized in that the quick-installation structure includes a connecting end one located at one end of the frame strip and a connecting end two located at one end of another frame strip, the connecting end one having a first insertion part and a second insertion part arranged along the length direction of the connecting end one, the connecting end two having a first insertion groove and a second insertion groove for the first insertion part to be inserted into along the width direction of the connecting end two, the second insertion part being able to bend and deform under external force after being inserted into and extending out of the second insertion groove.
[0005] During installation, the first and second insertion parts of the first connecting end are inserted into the first and second insertion slots of the second connecting end. Then, the second insertion part is folded and deformed. Through the cooperation of the first insertion part and the second insertion slot, the first connecting end is limited in the length direction of the second connecting end. At the same time, through the cooperation of the second insertion part and the second insertion slot, the first connecting end is limited in the width direction of the second connecting end, thereby forming a fixed connection between the first connecting end and the second connecting end.
[0006] In the aforementioned quick-installation structure for door or window frames, both connecting end one and connecting end two include a frame body arranged along the length of the frame strip and a folded portion one located on one side of the frame body and folded relative to the frame body. The folded portion one of connecting end one has a clearance groove one, forming the aforementioned insertion portion one and insertion portion two on the folded portion one. This reduces the weight of connecting end one and connecting end two while improving their structural strength.
[0007] In the aforementioned quick-installation structure for door or window frames, the second insertion part has an installation hole. The installation hole facilitates the insertion of long tools such as pry bars during installation, allowing the first and second connection ends to fit more tightly through leverage. It also allows the second insertion part to be bent and deformed by hooking the installation hole with a hook.
[0008] In the quick-installation structure of the door or window frame described above, the frame body of the first connecting end and the second connecting end also has a second folding part that folds over relative to the frame body. The second folding part is located on the side of the frame body opposite to the first folding part and has the same folding direction as the first folding part.
[0009] In the aforementioned quick-installation structure for door or window frames, the width of the frame body is greater than the distance from the first insertion slot to the end face of the second connection end. Thus, after the first and second connection ends are assembled, the folded portion of the first connection end can cover the outer end of the second connection end.
[0010] In the aforementioned quick-installation structure for door or window frames, the folded portions of connecting end one and connecting end two have inwardly folded flanges on the side opposite to the frame body. An installation groove is formed between the flange of connecting end one and the frame body, and a clearance groove is formed on the flange of connecting end two. When connecting end one and connecting end two are assembled, the flange of connecting end one is embedded in the clearance groove, and the folded portion of connecting end two is embedded in the installation groove. After assembly, connecting end one and connecting end two further improve their fit, making the connection more compact and stable. Furthermore, connecting end one and connecting end two form a mutually enveloping effect, resulting in a more aesthetically pleasing appearance.
[0011] Compared with the prior art, the present invention has the following advantages:
[0012] 1. This utility model has a simple structure and ingenious design. Through the cooperation of the first plug-in part and the second plug-in slot, the first connecting end is limited in the length direction of the second connecting end. At the same time, through the cooperation of the second plug-in part and the second plug-in slot, the first connecting end is limited in the width direction of the second connecting end. This makes the first connecting end and the second connecting end fixedly connected. The installation operation is simple and quick, the installation efficiency is higher, and the connection stability is high.
[0013] 2. The folded part one and folded part two of the connecting end one and the connecting end two, as well as the flange, are tightly fitted together to form a mutual covering, making the connection between the connecting end one and the connecting end more compact, more stable, and more aesthetically pleasing.

Detailed Implementation
[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0023] Example 1
[0024] A quick-installation structure for door or window frames, such as Figure 1 , Figure 2 As shown, the door frame or window frame includes several long frame strips 1. The frame strips 1 are made of metal materials such as aluminum alloy or stainless steel. Both ends of the connected frame strips 1 are provided with connecting end 3 or connecting end 4. The frame strips 1 are assembled and fixed by connecting end 3 and connecting end 4 to form a square frame structure.
[0025] Specifically, such as Figure 2 , Figure 3As shown, the frame strip 1 includes a long, narrow frame body 21 and two folded portions 22 and 23 located on both sides of the frame body 21 and folded towards the same side, respectively. Each folded portion 23 has an inwardly folded flange 24 on the side opposite to the frame body 21. Figure 4 , Figure 5 , Figure 6 As shown, connecting end 3 and connecting end 4 are formed by cutting and processing the two ends of the frame strip 1. Both also include the aforementioned frame body 21, folded part 22, folded part 23, and flange 24. The folded part 22 of connecting end 3 has a recessed groove 44, forming a first insertion part 31 and a second insertion part 32. Both the first insertion part 31 and the second insertion part 32 extend along the length of connecting end 3. One side of the first insertion part 31 connects to the frame body 21 and extends to the end face of connecting end 3. The second insertion part 32 has a certain distance from the first insertion part 31 and its length is less than [a certain value]. The length of the first insertion part 31; the second connection end 4 has an insertion groove 41 and an insertion groove 42 along the width direction. The insertion groove 41 extends from the first folding part 22 through the frame body 21 and extends to the second folding part 23. The insertion groove 42 is located on the second folding part 23 and extends through the first folding part 22. When the first connection end 3 and the second connection end 4 are spliced, the first insertion part 31 is inserted into the first insertion groove 41, and the second insertion part 32 is inserted into the second insertion groove 42. Then, the end of the second insertion part 32 that extends out of the second insertion groove 42 is folded and deformed by external force so that it is folded 90° and fits against the first folding part 22. The engagement of the first insertion part 31 and the second insertion slot 42 limits the length of the first connection end 3 in the second connection end 4. Simultaneously, the engagement of the second insertion part 32 and the second insertion slot 42 limits the width of the second connection end 3 in the second connection end 4, thus creating a fixed connection between the first connection end 3 and the second connection end 4. For ease of installation, in this embodiment, the second insertion part 32 also has a mounting hole 32a. After the second insertion part 32 is inserted into the second insertion slot 42, the mounting hole 32a is located outside the second mounting slot 42, allowing operators to pass tools such as pry bars through the mounting hole 32a. Through leverage, the first connection end 3 and the second connection end 4 are tightly fitted together, and force can be applied to the second insertion part 32 by hooking it into the mounting hole 32a, causing the second insertion part 32 to fold and deform.
[0026] In this embodiment, the width of the frame body 21 is greater than the distance from the insertion slot 41 to the end face of the connecting end 4, so that when the connecting end 3 and the connecting end 4 are spliced, the folded part 23 of the connecting end 3 can cover the end face of the connecting end 4.
[0027] Furthermore, such as Figure 7As shown, a mounting groove 43 is formed between the flange 24 of the connecting end 3 and the frame body 21. A clearance groove 45 is opened on the flange 24 of the connecting end 4. When the connecting end 3 and the connecting end 4 are assembled, the flange 24 of the connecting end 3 is partially embedded in the clearance groove 45, and the folded part 23 of the connecting end 4 is partially embedded in the mounting groove 43, so that the connection between the connecting end 3 and the connecting end 4 is closed in a box shape.
[0028] Example 2
[0029] This embodiment is basically the same as the technical solution of Embodiment 1. The difference is that in this embodiment, the two plug-in parts 32 on the first connection end 3 are arranged at intervals, and the two plug-in slots 42 on the second connection end 4 are also two corresponding ones. When the two plug-in parts 32 are inserted into the two plug-in slots 42 respectively, the two plug-in parts 32 can be folded in opposite directions by external force.
[0030] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0031] Although this document frequently uses terms such as frame strip 1, frame body 21, and flange 24, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
