DETAILED DESCRIPTION

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] like Figures 1 to 3As shown, the utility model provides a sliding support for building doors and windows with improved safety, including a mounting arm 1, a force-bearing arm 2, a supporting arm 3, a guide arm 4 and an auxiliary arm 5. The mounting arm 1 is mounted on the wall to ensure the stability and reliability of the sliding support. One side of the mounting arm 1 is bent upward to form a slide groove 11, at least a portion of the force-bearing arm 2 is located in the slide groove 11, the force-bearing arm 2 is slidably connected to the slide groove 11, and one end of the force-bearing arm 2 away from the slide groove 11 is hinged to one end of the supporting arm 3. The doors and windows are mounted on the supporting arm 3, so that the supporting arm 3 can perform corresponding actions with the rotation of the force-bearing arm 2, thereby achieving the supporting effect on the doors and windows. The other end of the supporting arm 3 is hinged to one end of the guide arm 4, and the other end of the guide arm 4 is hinged to the mounting arm 1. A slider 6 is arranged between the force-bearing arm 2 and the guide arm 4, and at least a part of the slider 6 is located in the slide groove 11. The slider 6 is slidably connected to the slide groove 11, and one end of the auxiliary arm 5 is hinged to the slider 6, and the other end of the auxiliary arm 5 is hinged to the guide arm 4. The design of the auxiliary arm 5 further enhances the stability and load-bearing capacity of the sliding support, so that the sliding support can be more stable and reliable when bearing the weight of the door and window. That is, at least a part of the force-bearing arm 2 and the slider 6 is located in the slide groove 11, and the slider 6 is arranged between the force-bearing arm 2 and the guide arm 4, ensuring that the force-bearing arm 2 and the slider 6 can maintain stable sliding in the slide groove 11 when subjected to external force, and will not easily fall out, which can enhance the connection strength between the slider 6 and the slide groove 11, improve the load-bearing capacity of the sliding support, reduce the risk of the slider 6 falling out due to wear or external force, and thus improve the safety of the sliding support. In addition, the hinge can be connected by rivets to facilitate the rotation of the force arm 2, the supporting arm 3, the guide arm 4 and the auxiliary arm 5, so as to realize the opening and closing of the door and window. Of course, in actual design, the hinged structure can be designed according to actual needs.

[0038] like Figure 3 , Figure 4 As shown, in this embodiment, the height of the auxiliary arm 5 relative to the mounting arm 1 is equal to the height of the force-bearing arm 2 relative to the mounting arm 1, so that the force on the sliding support structure is more uniform, which not only improves the load-bearing capacity of the sliding support, but also reduces the risk of structural deformation or damage caused by uneven force.

[0039] like Figures 5 to 8 As shown, in this embodiment, the slider 6 includes a slider body 61 and a slider bottom shell 62 arranged in an upper and lower manner, and the slider body 61 is embedded in the slider bottom shell 62 to ensure the stability and accuracy of the structure of the slider 6. In addition, the slider body 61 is provided with a plurality of first positioning holes, and the slider bottom shell 62 is correspondingly provided with a plurality of first positioning columns, and the first positioning columns are plugged into the first positioning holes, thereby ensuring that the relative position between the slider body 61 and the slider bottom shell 62 is fixed, which facilitates the slider 6 to slide in the slide groove 11 and improves the stability of the assembly.

[0040] like Figures 5 to 8As shown, in this embodiment, a stressed arm bottom shell 21 is provided at the bottom of the stressed arm 2, and at least a portion of the stressed arm 2 is embedded in the stressed arm bottom shell 21, which not only enhances the overall structural strength of the stressed arm 2, but also provides additional protection for it. By embedding at least a portion of the stressed arm 2 in the stressed arm bottom shell 21, a close connection between the two can be ensured, and looseness or deformation caused by external factors can be reduced. In addition, a second positioning column is provided on the stressed arm bottom shell 21, and a plurality of second positioning holes are correspondingly provided on the stressed arm 2. The second positioning column is plugged into the second positioning hole, so as to achieve precise alignment and fixation between the stressed arm 2 and the stressed arm bottom shell 21, and ensure a stable and reliable connection between the two, and avoid displacement or shaking that may occur during use.

[0041] like Figures 5 to 8 As shown, in this embodiment, a connecting plate 7 is also provided in the slide groove 11, one end of the connecting plate 7 is connected to the slider 6, and the other end of the connecting plate 7 is connected to the force arm 2, so that the slider 6 and the force arm 2 slide synchronously in the slide groove 11, thereby realizing the smooth opening and closing of the door and window. A limiting portion 12 is provided on the mounting arm 1 to limit the position of the connecting plate 7, further enhancing the safety and stability of the sliding support. The main function of the limiting portion 12 is to limit the position of the connecting plate 7 in the slide groove 11, prevent it from excessive movement or derailment, ensure the stability of the sliding support during the opening or closing process of the door and window, and avoid the potential safety hazards caused by the displacement of the connecting plate 7.

[0042] like Figures 5 to 8 As shown, in this embodiment, a damping component 8 is also provided in the slide groove 11, and the damping component 8 is engaged with the slider 6. The main function of the damping component 8 is to provide resistance to adjust the moving speed of the slider 6 in the slide groove 11, so as to achieve smooth and safe sliding. In addition, the engaging connection between the damping component 8 and the slider 6 ensures a close fit and stability between the two, so that the damping component 8 moves with the slider 6, which is not only convenient for installation and disassembly, but also can maintain the effectiveness of the damping component 8 during use, and is not easy to fall off or shift. In addition, a damping installation position is provided on the slider 6, and at least a part of the damping component 8 is arranged on the damping installation position, so as to ensure that the damping component 8 can be firmly installed on the slider 6 and move with the movement of the slider 6.

[0043] like Figures 1 to 3 As shown, in this embodiment, the slide groove 11 is arranged along the length direction of the mounting arm 1, ensuring that the slider 6 can slide smoothly and stably along the length direction of the mounting arm 1. The existence of the slide groove 11 not only provides a clear moving path for the slider 6, but also increases the stability and reliability of sliding.

[0044] like Figure 2 , Figure 3As shown, in the present embodiment, the hinged position of the force arm 2 and the connecting plate 7 is the fixed point A, the hinged position of the force arm 2 and the supporting arm 3 is the force point B, the angle between the line connecting the fixed point and the force point and one side of the force arm 2 close to the slider 6 is an acute angle, that is, the straight line connecting the two rivets of the force arm 2 and one side of the force arm 2 close to the slider 6 have an angle a, and the angle a is an acute angle, the corner of the sliding support is just closed in place, thereby avoiding the problem of increasing the wrap angle to limit the closing of the sliding support in the traditional design, and the elimination of the wrap angle not only simplifies the structure of the sliding support, but also reduces the risk of abnormal noise and deformation caused by long-term friction between the sliding support and the wrap angle.

[0045] like Figures 2 to 3 As shown, in this embodiment, the intersection of the line between the force point and the fixed point and the outer side of the mounting arm 1 is the fulcrum C, and the distance D1 between the fulcrum and the fixed point is greater than the distance D2 between the fulcrum and the force point. When the door and window apply pressure to the force point, due to the shorter distance between the fulcrum and the force point, the force arm 2 can generate a larger torque, thereby more effectively resisting the weight of the door and window. At the same time, due to the longer distance between the fulcrum and the fixed point, the overall structure of the sliding support is more stable and less prone to deformation or damage.

[0046] like Figures 1 to 3 As shown, in this embodiment, a clamping block 9 connected to one side of the door and window is provided at the force point, and a supporting protrusion 91 is provided at the bottom of the clamping block 9 close to the door and window. The supporting protrusion 91 is connected to the bottom of the door and window, so that the center of gravity of the door and window is transferred from the center to the corner, so that the sliding support can better disperse and bear the weight of the door and window, which not only improves the load-bearing capacity of the sliding support, but also effectively reduces the occurrence of falling doors and windows, providing residents with a safer and more reliable use experience.

[0047] like Figures 1 to 3As shown, in this embodiment, the side of the clamping block 9 is provided with a plurality of first threaded holes, and the side top screw fixes the clamping block 9 to the door and window through the first threaded hole, ensuring that the door and window can remain stable when subjected to external force, and is not prone to shaking or displacement. In addition, the clamping block 9 is provided with a second threaded hole, and the top top screw is threadedly connected to the clamping block 9 through the second threaded hole. An adjustment rod is provided on the supporting arm 3, and the clamping block 9 is sleeved on the adjustment rod through the second threaded hole, and the top top screw abuts against the adjustment rod. The adjustment rod is set at the force point, and the clamping block 9 is sleeved on the adjustment rod through the second threaded hole, and the top top screw abuts against the adjustment rod to adjust the gap between the door and window and the sliding support. The top top screw is adjusted downward along the second threaded hole, and the clamping block 9 will be subjected to an upward thrust, and the clamping block 9 moves upward, and the gap between the door and window and the sliding support becomes larger, so that the door and window will not press the force arm 2 of the sliding support, and the sliding support cannot be opened or closed normally. In addition, a plastic ring is provided at the bottom of the top top screw, and the top top screw is in contact with the adjusting rod through the plastic ring, which plays a buffering role for the top top screw and prevents the top top screw adjustment from causing damage to the adjusting rod.

[0048] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0049] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
