Folding doors are widely used due to their aesthetic appeal and wide field of vision. Related technologies for folding doors include door panels and sealing strips between adjacent door panels to ensure the door's airtightness when closed. As the height of the door panels increases, a central hinge is added between the two panels to prevent misalignment or deformation. However, this central hinge can cause the sealing strip to break, leading to a decrease in the folding door's airtightness and insulation. Utility Model Content

[0003] The purpose of this utility model is to provide a windproof buckle and door and window structure to prevent problems such as misalignment or even deformation in the middle of the door leaf, and to ensure the sealing and heat insulation of the door and window structure.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A windproof buckle is provided between the frames of two door leaves of a door and window structure, or between the frame of the door leaf and the frame of the door frame used to install the door leaf. A sealing strip extends along the length of the frame. When the door leaf is closed, the two frames are sealed together by the sealing strip. A connecting part is provided on the frame, and the connecting part and the sealing strip are arranged along the thickness of the frame.

[0006] The windproof buckle includes a first base and a second base, which are respectively disposed at the connecting parts of the two side frames. The first base is provided with a buckle, and the second base is provided with a lock groove. When the door is closed, the buckle is engaged with the lock groove.

[0008] In some possible implementations, both the first base and the second base have one or more mounting holes, and both the first base and the second base are connected to the connecting portion through the mounting holes. The one or more mounting holes are symmetrical about the first symmetrical surface.

[0009] In some possible implementations, the first base on the side opposite to the latch and the second base on the side opposite to the lock groove are both provided with mounting structures that connect to the connecting part; when the latch is embedded in the lock groove, the first base and the second base are symmetrical about the plane between them, and the mounting structures on the first base and the mounting structures on the second base are symmetrical about the second symmetrical plane.

[0010] In some possible implementations, the mounting structure includes a hook and a boss arranged along a second direction, the groove of the hook facing the boss, the second direction being parallel to the thickness direction of the frame; the connecting portion is provided with a latching protrusion and a groove, the hook hooking the latching protrusion; the boss is disposed in the groove.

[0011] In some possible implementations, the latch and the first base are integrally formed.

[0012] In some possible implementations, the latch includes a roller and a mounting shaft, the first base includes a support portion, the roller is sleeved on and rotatably connected to the mounting shaft, and the mounting shaft is disposed on the support portion.

[0013] In some possible implementations, the inner wall of the lock groove is provided with an inclined guide surface, so that the width of the lock groove opening is greater than the width of the groove bottom.

[0014] In some possible implementations, the frame includes two mounting profiles disposed along the thickness direction of the frame and a heat insulation strip disposed between the two mounting profiles, wherein the joint between the heat insulation strip and the mounting profiles forms the connection portion.

[0015] A door and window structure includes two frame frames and at least one windproof buckle as described in any of the preceding claims, wherein the windproof buckle is disposed between the frame frames of the two door leaves of the door and window structure or between the frame frames of the door leaves and the frame frame of the door frame for mounting the door leaves.

[0016] The first base and the second base of the windproof buckle are respectively provided at the connection part of the two frames. When the door is closed, the buckle on the first base is engaged with the lock groove on the second base.

[0017] In some possible implementations, the door and window structure further includes two hinges, with the two hinges provided between the two side frames along the length of the side frames, and at least one windproof buckle provided between the two hinges.

[0018] The beneficial effects of this utility model are:

[0019] This utility model provides a windproof latch and door / window structure. Firstly, by installing a windproof latch between two door panels or between a door panel and the door frame, the latch engages with the lock groove when the door is closed. The windproof latch connects the two door panels or the door panel and the door frame, replacing the intermediate hinge and effectively resisting wind pressure, preventing potential misalignment or deformation of the door panels. Secondly, because the connecting part and sealing strip are arranged along the thickness direction of the frame, after the windproof latch and connecting part are connected, the windproof latch and sealing strip are arranged along the thickness direction of the frame, allowing for installation without disconnecting the sealing strip. This ensures the sealing and insulation properties of the door / window structure. Furthermore, compared to installing an intermediate hinge on the door panel, the windproof latch is located in the middle of the two frame sides along the thickness direction, avoiding exposure to the outside of the door / window structure, resulting in a cleaner and more aesthetically pleasing appearance.

[0036] like Figures 1-4 As shown, this embodiment provides a door and window structure and a windproof latch 3. Exemplarily, the door and window structure can be a folding door or a swing door, etc., and is not limited thereto.

[0037] In one embodiment, the door and window structure is a folding door, comprising two door panels. A windproof buckle 3 is disposed between the frame 1 of the two door panels, and a sealing strip 2 extends along the length of the frame 1. When the door panels are closed, the frame 1 of the two door panels is sealed and connected by the sealing strip 2. A connecting portion 11 is provided on the frame 1, and the connecting portion 11 and the sealing strip 2 are arranged along the thickness direction of the frame 1. The windproof buckle 3 includes a first base 31 and a second base 33, corresponding to the connecting portion 11 of the two frame 1. A latch 32 is provided on the first base 31, and a lock groove 34 is provided on the second base 33. When the door panels are closed, the latch 32 is engaged with the lock groove 34.

[0038] In another embodiment, the door and window structure is a casement door, comprising a door leaf and a door frame for installing the door leaf. The door leaf and door frame are each provided with a frame 1. A windproof buckle 3 is disposed between the frame 1 of the door leaf and the frame 1 of the door frame. A sealing strip 2 extends along the length of the frame 1. When the door leaf is closed, the frame 1s of the two door leaves are sealed together by the sealing strip 2. A connecting portion 11 is provided on the frame 1, and the connecting portion 11 and the sealing strip 2 are arranged along the thickness direction of the frame 1. The windproof buckle 3 includes a first base 31 and a second base 33, corresponding to the connecting portions 11 of the two frame 1s. A latch 32 is provided on the first base 31, and a lock groove 34 is provided on the second base 33. When the door leaf is closed, the latch 32 is engaged with the lock groove 34.

[0039] Optionally, two hinges 4 are provided between the two frame frames 1 along the length of the frame frame 1. The two hinges 4 are respectively located at the top and bottom between the two frame frames 1 to connect the two frame frames 1 and enable the opening and closing of the door. At least one windproof latch 3 is provided between the two hinges 4. The number of windproof latches 3 can be appropriately increased according to the actual needs such as the height of the door to improve the performance of the door.

[0040] The two parts of the windproof buckle 3, namely the first base 31 with a latch 32 and the second base 33 with a locking groove 34, are respectively installed on the frame 1 of the two door leaves. As the door leaves are opened, the latch 32 and the locking groove 34 separate. As the door leaves are closed, i.e., with the force of closing the door leaves, the latch 32 and the locking groove 34 engage with each other. Specifically, the latch 32 and the locking groove 34 can be designed by trajectory simulation through experiments and other means so that the latch 32 and the locking groove 34 can be perfectly engaged when the door leaves are closed.

[0041] On the one hand, by installing a windproof buckle 3 between the two door leaves, when the door leaves are closed, the buckle 32 is engaged with the lock groove 34. The windproof buckle 3 is used to connect the two frame 1, replacing the middle hinge, which can play a role in resisting wind pressure and effectively prevent the door leaves from being misaligned or even deformed.

[0042] On the other hand, since the connecting part 11 and the sealing strip 2 are arranged along the thickness direction of the frame 1, after the windproof buckle 3 and the connecting part 11 are connected, the windproof buckle 3 and the sealing strip 2 are arranged along the thickness direction of the frame 1. Therefore, the installation of the windproof buckle 3 does not require disconnecting the sealing strip 2, thus ensuring the sealing and heat insulation properties of the door and window structure. Furthermore, compared to installing a middle hinge on the door leaf, the windproof buckle 3 is located between the two door leaves, avoiding exposure to the outside of the door and window structure, making the visible surface simpler and more aesthetically pleasing.

[0043] like Figure 1 As shown, in one embodiment, the latch 32 and the first base 31 are integrally formed, which has good structural stability, is easy to manufacture, and can save costs. Exemplarily, the first base 31 includes a base plate 311, and the latch 32 is disposed on one side of the base plate 311.

[0044] The second base 33 includes a base plate 311 and two protrusions 35 on one side of the base plate 311, forming a locking groove 34. Optionally, the base plate 311 and the protrusions 35 are integrally formed. The inner sidewall of the locking groove 34 is provided with an inclined guide surface 351, so that the width of the groove opening of the locking groove 34 is greater than the width of the groove bottom. That is, the two protrusions 35 are provided with an inclined guide surface 351 on the side facing each other, so that the latch 32 can be fitted into the locking groove 34. Exemplarily, the guide surface 351 is a plane.

[0045] The plane in the middle of the first direction of the windproof buckle 3 is the first symmetry plane A. The first base 31, the buckle 32, the second base 33 and the locking groove 34 are all symmetrical along the first symmetry plane A. The first direction is parallel to the length direction of the frame 1. Therefore, there is no need to distinguish the structure along the first direction during installation. It can be installed arbitrarily, which reduces the difficulty of installation.

[0046] Optionally, both the first base 31 and the second base 33 have one or more mounting holes 313. Both the first base 31 and the second base 33 are connected to the connecting part 11 through the mounting holes 313. The one or more mounting holes 313 are symmetrical along the first plane of symmetry A. Specifically, the connecting part 11 is a threaded hole on the frame 1. Fasteners 5, such as screws, pass through the mounting holes 313 and the threaded holes and are threadedly connected to the threaded holes. For example, four mounting holes 313 are provided. The four mounting holes 313 on the first base 31 are located on both sides of the latch 32 along the first direction. Both the four mounting holes 313 and the latch 32 are symmetrical along the first plane of symmetry A. The four mounting holes 313 on the second base 33 are located on both sides of the lock groove 34 along the first direction. Both the four mounting holes 313 and the lock groove 34 are symmetrical along the first plane of symmetry A.

[0047] like Figure 1 and Figure 2As shown, the first base 31, on the side opposite to the latch 32, and the second base 33, on the side opposite to the lock groove 34, are both provided with mounting structures 312 that connect to the connecting part 11. When the latch 32 is embedded in the lock groove 34, the first base 31 and the second base 33 are aligned along the plane between them, which is the second plane of symmetry B. The mounting structures 312 on the first base 31 and the second base 33 are symmetrical along the second plane of symmetry B. With the first base 31, latch 32, second base 33, and lock groove 34 all symmetrical along the first plane of symmetry A, and the two mounting structures 312 symmetrical along the second plane of symmetry B, the assembly of the first base 31 and the second base 33 does not require differentiation between the two door panels, allowing for arbitrary installation and reducing installation difficulty. Optionally, the base plate 311 is a rectangular plate.

[0048] Exemplarily, the mounting structure 312 includes a hook 3121 and a boss 3122 arranged along a second direction. The groove of the hook 3121 faces the boss 3122, and the second direction is parallel to the thickness direction of the frame 1. The connecting part 11 is provided with a latching protrusion 111 and a groove. The hook 3121 hooks the latching protrusion 111; the boss 3122 is disposed in the groove. When assembling the first base 31, firstly, the hook 3121 hooks the latching protrusion 111, then the first base 31 is rotated so that the boss 3122 is inserted into the groove, and finally, the four fasteners 5 are installed corresponding to the four mounting holes 313. When assembling the second base 33, the assembly method of the first base 31 can be referred to, and will not be described again.

[0049] like Figure 3 and Figure 4 As shown, in one embodiment, the frame 1 includes two mounting profiles 12 arranged along the thickness direction of the frame 1 and a heat insulation strip 13 disposed between the two mounting profiles 12. The mounting profiles 12 are, for example, aluminum alloy, plastic steel, etc., while the heat insulation strip 13 is a material used to block heat conduction and is usually installed between the mounting profiles 12 to form a thermal break structure, thereby improving the heat insulation performance. The joint between the heat insulation strip 13 and the mounting profile 12 forms a connection part 11. The heat insulation strip 13 forms a protrusion 111, the mounting profile 12 forms a protrusion 112, and a sealing strip 2 is installed on the mounting profile 12. A groove is formed between the sealing strip 2 and the protrusion 112, and a boss 3122 is disposed in the groove. Furthermore, the side of the boss 3122 abuts against the sealing strip 2, improving the connection reliability. The mounting profile 12 and the heat insulation strip 13 of one frame 1 are simultaneously connected to the first base 31, that is, the first base 31 serves to connect the mounting profile 12 and the heat insulation strip 13. The mounting profile 12 and the heat insulation strip 13 of the other frame 1 are simultaneously connected to the second base 33, that is, the second base 33 serves to connect the mounting profile 12 and the heat insulation strip 13. Thus, the windproof buckle 3 serves to connect the heat insulation strip 13 and the mounting profile 12, and realizes the arrangement of the sealing strip 2 and the windproof buckle 3 in the thickness direction of the frame 1.

[0050] like Figure 3 and Figure 5 As shown, optionally, heat insulation strips 13 of different thicknesses or related parameters can be selected according to requirements. As long as the structure of the protrusion 111 of the heat insulation strip 13 is the same, the windproof buckle 3 can be installed. Replacing different heat insulation strips 13 will not affect the installation of the windproof buckle 3. Figure 3 The insulation strip 13 in the middle is relatively thick. Figure 5 The insulation strip 13 in the two is thinner, but the truncation 111 structure of the two is the same.

[0051] like Figure 3 As shown, optionally, both the thermal insulation strip 13 and the mounting profile 12 are equipped with sealing strips 2, which allows for a reasonable layout of the sealing strips 2 and the windproof buckle 3, preventing interference with the installation of the sealing strips 2. Further, different sealing strips 2 are selected based on the different structures of the thermal insulation strip 13 and the mounting profile 12. For example, a second sealing strip 22 is installed on the thermal insulation strip 13, and a first sealing strip 21 is installed on the mounting profile 12. Each of the two door leaf frames 1 has at least two sealing strips 2 along its thickness direction, with a connecting portion 11 located between the two sealing strips 2. By increasing the number of sealing strips 2, the sealing and heat insulation properties are further improved. Furthermore, by reasonably arranging the connection positions for installing the windproof buckle 3, the installation positions of the windproof buckle 3 and the sealing strips 2 are prevented from interfering with each other. In one embodiment, the frame 1 has three spaced-apart sealing strips 2 along its thickness direction, with a connecting portion 11 between two sealing strips 2. Optionally, the windproof buckle 3 is located between two sealing strips 2 near the outside.

[0052] In another embodiment, such as Figure 5 As shown, the mounting profile 12 is equipped with a sealing strip 2, while the heat insulation strip 13 is not equipped with a sealing strip 2, simplifying the structure.

[0053] like Figure 6 As shown, in another embodiment, the latch 32 includes a roller 321 and a mounting shaft 322. The first base 31 includes a support portion 314. The roller 321 is sleeved on and rotatably connected to the mounting shaft 322, which is located on the support portion 314. Optionally, the roller 321 is a brass roller, which serves to eliminate noise and reduce installation accuracy. Further, the base plate 311 of the first base 31 is symmetrically provided with two support portions 314 along a first direction. The mounting shaft 322 is mounted on the two support portions 314, the roller 321 is located between the two support portions 314, and the mounting holes 313 are located on both sides of the two support portions 314. Further, the base plate 311 of the second base 33 is provided with two protrusions 35, and a locking groove 34 is formed between the two protrusions 35. The inclined guide surfaces 351 of the two protrusions 35 facing each other are both arc surfaces. Optionally, the two end faces of the roller 321 are slidably connected to the two support parts 314 respectively, and the two support parts 314 play a limiting role in the roller 321 to prevent the roller 321 from shaking up and down.

[0054] Optionally, taking the first base 31 as an example, the mounting holes 313 are divided into elongated holes 3132 and oblong holes 3131 arranged along the width direction of the base plate 311, and the elongated holes 3132 and oblong holes 3131 are symmetrically arranged along the length direction of the base plate 311. The connecting part 11 is provided with positioning holes and threaded holes. The positioning holes and elongated holes 3132 are correspondingly arranged, and the oblong holes 3131 and threaded holes are correspondingly arranged. Screws pass through the oblong holes 3131 and threaded holes and are threadedly connected to the threaded holes, realizing the connection between the first base 31 and the connecting part 11. The positioning pin passes through the elongated holes 3132 and positioning holes and is inserted into the positioning holes, realizing the positioning of the first base 31 and the connecting part 11. By setting the oblong holes 3131 and elongated holes 3132, the position can be adjusted along the length direction of the frame 1, so as to facilitate the alignment and installation of the first base 31 and the second base 33, thereby reducing the difficulty of on-site installation. Optionally, the first base 31 may also be provided with four identical mounting holes 313, all of which are installed by fasteners 5. For details, please refer to the previous embodiment, and will not be repeated here.

[0055] Optionally, the base plate 311 of the second base 33 is provided with an avoidance groove 331 to avoid interference between the base plate 311 and the latch 32, and to ensure that the latch 32 is stably embedded in the latch groove 34.

[0056] The structures of the first base 31 and the second base 33 can be configured according to requirements and are not limited. The two types of first bases 31 and the two types of latches 32 described above can be combined arbitrarily. The two types of second bases 33 and the two types of locking grooves 34 described above can be combined arbitrarily.

[0057] In another embodiment, the second base 33 may have only one protrusion 35, which cooperates with the latch 32. The side with the protrusion 35 provides wind resistance on one side, but the installation accuracy requirement is lower and it is easier for workers to install.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
