[0030] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] To achieve the objectives of this application, secondary sliders and secondary connecting rods are added to the base plates on both sides. This makes the hinge more stable overall, reduces hinge deformation and swaying after opening, and enhances its safety and reliability. The main and secondary sliders feature a plastic-coated design, meaning the sliders are made of stainless steel wrapped with a layer of high-performance plastic. This plastic-coating design improves the product's lifespan and safety. Even if the plastic fails due to factors such as fire, the internal stainless steel material will prevent the sliders from detaching, avoiding window sash detachment and other risks. These two design features significantly increase the safety and reliability of this push-out sliding hinge.

[0032] This application provides an embodiment of a multi-link push-out sliding hinge, see [link to previous document]. Figure 1-3 It includes a first base plate 1 and a second base plate 8 that are parallel to each other, and a scissor lift is provided between the first base plate 1 and the second base plate 8.

[0033] The scissor lift is rotatably connected to the first base plate 1 at the first connecting part of the first base plate 1 and slidably connected to the second connecting part of the first base plate 1 via the main slider 14 of the first base plate. The scissor lift is rotatably connected to the main slider 14 of the first base plate. The scissor lift is rotatably connected to the second base plate 8 at the first connecting part of the second base plate 8 and slidably connected to the second connecting part of the second base plate 8 via the main slider 84 of the second base plate. The scissor lift is rotatably connected to the main slider 84 of the second base plate.

[0034] The scissor lift is rotatably connected to the first base plate sub-slider 12 via the first auxiliary connecting arm 2. The first base plate sub-slider 12 is slidably connected to the first base plate 1, or / and the scissor lift is connected to the second base plate sub-slider 82 via the second auxiliary connecting arm 7. The second base plate sub-slider 82 is slidably connected to the second base plate 8.

[0035] This utility model's push-out sliding hinge enables parallel opening and closing of the hinge, thus adapting to the parallel opening and closing actions when installed on a sliding window profile. During opening, the connecting arms gradually open from a parallel state, causing the two base plates to gradually move away. The sliders in the base plates gradually approach the hinge's limiting sliders until the hinge is opened to its maximum travel position. At this point, the main sliders of both base plates contact their respective limiting sliders, preventing them from sliding further forward and thus limiting the hinge's maximum opening travel.

[0036] In one embodiment of this application, the scissor lift includes a first connecting arm 3, a second connecting arm 4, a third connecting arm 5, and a fourth connecting arm 6. The first connecting arm 3 and the second connecting arm 4 are rotatably connected at the middle to form an X-shaped assembly, and the third connecting arm 5 and the fourth connecting arm 6 are rotatably connected at the middle to form an X-shaped assembly.

[0037] Understandably, the scissor lift and main and auxiliary sliders are used as components to realize the opening and closing function. Each component is connected by rivets, and its slider is located in the corresponding base plate groove. The first connecting arm 3, the first auxiliary connecting arm 2 and the second connecting arm 4 form a fork shape, and the third connecting arm 5, the second auxiliary connecting arm 7 and the fourth connecting arm 6 form a fork shape. The two ends of the connecting arms of the two fork shapes are respectively connected to the first base plate 1 or the second base plate 8, and the auxiliary connecting arms are respectively connected to the corresponding auxiliary sliders to realize the parallel opening and closing of the hinge.

[0038] In one embodiment of this application, the first end of the first connecting arm 3 is rotatably connected to the first connecting portion of the first base plate 1, and the second end is rotatably connected to the first end of the fourth connecting arm 6. The second end of the fourth connecting arm 6 is rotatably connected to the first connecting portion of the second base plate 8. The first end of the second connecting arm 4 is rotatably connected to the main slider 14 of the first base plate, and the second end is rotatably connected to the first end of the third connecting arm 5. The second end of the third connecting arm 5 is rotatably connected to the main slider 84 of the second base plate. The two ends of the first auxiliary connecting arm 2 are rotatably connected to the auxiliary slider 12 of the first base plate and the second connecting arm 4, respectively. The two ends of the second auxiliary connecting arm 7 are rotatably connected to the second base plate 8 and the third connecting arm 5, respectively.

[0039] In one embodiment of this application, the hinge further includes a first base plate pad 11 and a second base plate pad 81 respectively fixed on the first base plate 1 and the second base plate 8. The first end of the first connecting arm 3 and the first base plate pad 11 are rotatably connected to the first connecting part of the first base plate 1, and the second end of the fourth connecting arm 6 is rotatably connected to the second base plate pad 81 at the first connecting part of the second base plate 8.

[0040] The push-out sliding hinge of this utility model has a stainless steel base plate fixed in the base plate groove. The first connecting arm 3 and the fourth connecting arm 6 are connected by rivets. The base plate can improve the strength of the base plate and enhance the safety and reliability of the product.

[0041] In one embodiment of this application, the first end of the first connecting arm 3 and the first base plate pad 11 are riveted together at the first connecting part of the first base plate 1 by a first eccentric rivet 31, and the second end of the fourth connecting arm 6 and the second base plate pad 81 are riveted together at the first connecting part of the second base plate 8 by a second eccentric rivet 62.

[0042] The closing distance between the two base plates of the hinge can be controlled by adjusting the first eccentric rivet 31 and the second eccentric rivet 62, thus satisfying the sealing adjustment of the sliding window in actual use. Of course, the eccentric rivet structure is not essential. Even without this structure, ordinary rivets can be used to install and use the product, but the eccentric adjustment function will no longer be available.

[0043] In one embodiment of this application, the first auxiliary connecting arm 2 and the first base plate auxiliary slider 12 are riveted together by the first auxiliary slider rivet 21, the first end of the second connecting arm 4 and the first base plate main slider 14 are riveted together by the first main slider rivet 41, the first auxiliary connecting arm 2 and the second connecting arm 4 are riveted together by the first rivet 42, the second connecting arm 4 and the third connecting arm 5 are riveted together by the second rivet 51, the second auxiliary connecting arm 7 and the third connecting arm 5 are riveted together by the third rivet 53, the third connecting arm 5 and the second base plate main slider 84 are riveted together by the second main slider rivet 54, the first connecting arm 3 and the fourth connecting arm 6 are riveted together by the fourth rivet 61, and the second auxiliary connecting arm 7 and the second base plate auxiliary slider 82 are riveted together by the second auxiliary slider rivet 71.

[0044] In one embodiment of this application, the first connecting arm 3 and the second connecting arm 4 are rotatably connected at the middle by a first central rivet 32 ​​to form an X-shaped assembly, and the third connecting arm 5 and the fourth connecting arm 6 are rotatably connected at the middle by a second central rivet 52 to form an X-shaped assembly.

[0045] In one embodiment of this application, the first base plate 1 and the second base plate 8 are U-shaped grooves. The side enclosures of the opening of the first base plate 1 are used to clamp the first base plate main slider 14 and the first base plate secondary slider 12 to slide along its U-shaped slide. The side enclosures of the opening of the second base plate 8 are used to clamp the second base plate main slider 84 and the second base plate secondary slider 82 to slide along its U-shaped slide.

[0046] In one embodiment of this application, a first base plate limiting slider 13 for limiting is fixed between the first base plate main slider 14 and the first base plate secondary slider 12 and located on the first base plate 1; a second base plate limiting slider 83 for limiting is fixed between the second base plate main slider 84 and the second base plate secondary slider 82 and located on the second base plate 8.

[0047] The first base plate limiting slider 13 is located in the first base plate groove. The second base plate limiting slider 83 works similarly to the first base plate limiting slider. By fixing the base plate limiting slider to the base plate and the window sash profile with screws, it limits the maximum opening stroke of the hinge. The base plate limiting slider has holes that can be matched with the pre-drilled holes in the base plate to fix it to the window sash profile, thus achieving free control of the maximum opening stroke.

[0048] In one embodiment of this application, the first base plate 1 and the second base plate 8 are respectively fixed to the window sash and the window frame.

[0049] The technical solution of this utility model will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0050] See Figures 1 to 3 As shown, in this embodiment, the first base plate 1 and the second base plate 8 are respectively installed and fixed on the window sash and the window frame.

[0051] The hinge mainly includes a first base plate 1, a first base plate main slider 14, a first base plate secondary slider 12, a first secondary connecting arm 2, a first connecting arm 3, a second connecting arm 4, a third connecting arm 5, a fourth connecting arm 6, a second base plate 8, a second base plate main slider 84, a second base plate secondary slider 82, and a second secondary connecting arm 7. A first base plate pad 11 is fixed to the front end of the base plate in a sliding groove in the first base plate 1. The first base plate main slider 14, the first base plate secondary slider 12, and the first base plate limiting slider 13 are also provided for sliding within the groove. The second base plate 8 slides in the groove, and a second base plate pad 81 is fixed to the front end of the base plate in the groove. It also has a second base plate main slider 84, a second base plate auxiliary slider 82, and a second base plate limiting slider 83 that can slide in the groove. Its first auxiliary connecting arm 2 is riveted to the first base plate auxiliary slider 12 by a first auxiliary slider rivet 21, its first connecting arm 3 is riveted to the first base plate pad 11 by a first eccentric rivet 31, and its second connecting arm 4 is riveted to the first base plate main slider 14 by a first main slider rivet 41. The second connecting arm 4 and the first auxiliary connecting arm 2 are riveted together by the first rivet 42. The second connecting arm 4 and the first connecting arm 3 are riveted together by the first center rivet 32. The second connecting arm 4 and the third connecting arm 5 are riveted together by the second rivet 31. The fourth connecting arm 6 and the first connecting arm 3 are riveted together by the fourth rivet 61. The fourth connecting arm 6 and the third connecting arm 5 are riveted together by the second center rivet 52. The second auxiliary connecting arm 7 is riveted together by the second auxiliary slider rivet 71 and the second base plate auxiliary slider 82. The fourth connecting arm 6 is riveted together by the second eccentric rivet 62 and the second base plate pad 81. The third connecting arm 5 is riveted together by the second main slider rivet 54 and the second base plate main slider 84. The third connecting arm 5 and the second auxiliary connecting arm 7 are riveted together by the third rivet 53. The above components are riveted together to form an assembly for opening and closing, so as to realize the parallel opening and closing of the hinge. In this embodiment, after being installed on the curtain wall profile, the parallel opening and closing of the window sash can be realized, as well as the maximum opening stroke of the window sash can be realized and limited.

[0052] Each main and auxiliary slider is respectively located in the groove of the first base plate 1 and the second base plate 8. The base plate slider is plastic-coated, that is, the slider is made of stainless steel wrapped with a layer of high-performance plastic. The plastic-coating design can improve the service life and safety of the product. Even if the plastic fails due to factors such as fire, the internal stainless steel material can prevent the slider from falling off, avoiding the window sash from falling off and other risks. It can realize the smooth parallel opening and closing of the sliding window profile.

[0053] The first base plate limiting slider 13 is used to limit the sliding stroke of the first base plate main slider 14. Similarly, the second base plate limiting slider 83 is used to limit the sliding stroke of the second base plate main slider 84. The base plate limiting slider can be fixed during installation by pre-drilling reserved holes in the sliding grooves of the first base plate 1 and the second base plate 8, so as to realize and limit the maximum opening stroke of the window sash after installation.

[0054] The adjustment components are respectively located at the ends of the first base plate 1 and the second base plate 8. The first eccentric rivet 31 rivets the first base plate pad 11 and the first connecting arm 3 together, and the first base plate pad 11 is fixed to the end of the first base plate 1. The second eccentric rivet 62 rivets the second base plate 8 and the fourth connecting arm 6 together. By rotating the corresponding eccentric rivet, the closing distance of the two base plates can be adjusted to meet the adjustment requirements of the sliding window, i.e., the sealing adjustment. This structure is not necessary. Even if this structure is not present, it can be replaced with ordinary rivets to meet the product installation and use, but it will not have the eccentric adjustment function.

[0055] In this embodiment, the installation process of the push-out sliding hinge is as follows:

[0056] Place the first base plate 1 in the reserved position of the window sash. First, screw in the fastening screw at the elongated hole at the front end of the first base plate 1. Then, after confirming that the hinge installation position is centered by measuring tools such as calipers, screw in the fastening screws in the mounting holes of the first base plate 1 in sequence to fix it. After determining the maximum opening stroke to be achieved, the first base plate limiting slider 13 is fixed in the relative position by screwing in the fastening screw.

[0057] Place the second base plate 8 in the reserved position on the window frame. First, screw in the fastening screw at the elongated hole at the front end of the second base plate 8. Then, after confirming that the hinge installation position is centered by measuring tools such as calipers, screw in the fastening screws at the mounting holes of the second base plate 8 in sequence to fix it. After determining the maximum opening stroke to be achieved, fix the second base plate limit slider 62 in the relative position by screwing in the fastening screw. Then close the window sash and observe whether the window sash is in the middle of the window frame. If it is in the middle position, the installation is complete.

[0058] For example, push-out sliding hinges can be installed on the top, bottom, left, and right sides of the curtain wall profile window sash, with the top and bottom being the guide sides and the left and right sides being the load-bearing sides.

[0059] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
