[0002] In the building door and window industry, sliding stays are an important hardware accessory and are widely used in the opening and closing operations of various doors and windows. Traditional sliding stay designs usually adopt a relatively simple structure, mainly including basic components such as bottom rails, sliders and force arms, and the doors and windows are opened and closed by sliding the sliders.

[0003] In the prior art, the straight line connecting the two rivets of the force-bearing arm is parallel to the horizontal line. However, with this design, the corners of the sliding support are prone to not closing properly. In order to solve this problem, it is often necessary to increase the wrap angle at the corners of the sliding support in traditional designs to limit the closing of the sliding support. However, the long-term friction between the supporting arm of the sliding support and the wrap angle may not only produce abnormal noises, but also cause the supporting arm to deform, and the deformed supporting arm will further aggravate the problem of the corners of the sliding support not closing properly. In addition, the sliding support fastens the supporting arm to the door and window with screws. However, since the gravity of the doors and windows is mainly concentrated in the center of the doors and windows, this connection method is difficult to completely offset the gravity of the doors and windows. After long-term use, the doors and windows are prone to falling, which not only affects the use effect, but also may pose a threat to the safety of the residents.

DETAILED DESCRIPTION

[0030] 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.

[0031] like Figure 1 , Figure 2 As shown, the utility model provides a sliding support for building doors and windows, including a mounting arm 1, a load-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. A slider 6 is slidably arranged on the mounting arm 1, so that the load-bearing arm 2 can slide flexibly according to the opening and closing requirements of the doors and windows. The slider 6 is hinged to one end of the load-bearing arm 2, and the other end of the load-bearing arm 2 is hinged to one end of the supporting arm 3, so that the supporting arm 3 can perform corresponding actions with the rotation of the load-bearing arm 2, thereby realizing the supporting effect on the doors and windows. The doors and windows are mounted on the supporting arm 3, 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. The slider 6 is also connected to one end of the auxiliary arm 5, 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 doors and windows. 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.

[0032] 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 evenly distributed, 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.

[0033] like Figure 2 , Figure 4 , Figure 5As shown, in this embodiment, a slide groove 11 is provided on the mounting arm 1, and the slider 6 is slidably connected to the slide groove 11, and the slide groove 11 is provided along the length direction of the mounting arm 1, ensuring that the slider 6 can slide steadily and smoothly 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. The slider 6 includes a main body 61 and an extension portion 62 connected to the main body 61, at least a part of the extension portion 62 extends into the slide groove 11, and the extension portion 62 is slidably connected to the slide groove 11, so that the slider 6 can fit tightly in the slide groove 11, ensuring the accuracy and stability of sliding. At the same time, the sliding connection between the extension portion 62 and the slide groove 11 enables the slider 6 to move flexibly in the slide groove 11 to meet the different needs of opening and closing doors and windows. At least a portion of the outer wall of the extension portion 62 is recessed inward to form a slot, and the mounting arm 1 is correspondingly provided with a latching protrusion 12, at least a portion of the latching protrusion 12 is located in the slot, further enhancing the connection stability between the slider 6 and the mounting arm 1, and can effectively prevent the slider 6 from falling off or shaking during the sliding process, thereby improving the stability and safety of the entire sliding support structure.

[0034] like Figure 4 , Figure 5 As shown, in the present embodiment, the card slot includes a first card slot and a second card slot, and the first card slot and the second card slot are distributed on both sides of the extension portion 62, and in the height direction of the extension portion 62, there is a height difference H between the first card slot and the second card slot, thereby enhancing the connection stability between the slider 6 and the mounting arm 1. By setting the height difference in the height direction of the extension portion 62, the first card slot and the second card slot form different engaging positions, thereby improving the reliability of the connection.

[0035] like Figure 4 , Figure 5 As shown, in this embodiment, a connecting plate 7 is provided on the slider 6, and the force-bearing arm 2 and the auxiliary arm 5 are connected to the slider 6 through the connecting plate 7. The existence of the connecting plate 7 significantly enhances the connection stability between the force-bearing arm 2, the auxiliary arm 5 and the slider 6, so that the entire sliding support is more stable and reliable when bearing the weight of the door and window and performing the opening and closing operation. In addition, the connecting plate 7 includes a base 71 and a limiting portion 72 arranged at both ends of the base 71. The two limiting portions 72 are arranged at 90° with the base 71 to enclose and form an accommodating space for placing the slider 6. At least a part of the slider 6 is placed in the accommodating space, and the two limiting portions 72 limit the position of the slider 6. During the opening and closing process of the door and window, the slider 6 needs to slide in the slide groove 11. The limiting portion 72 on the connecting plate 7 can ensure that the slider 6 always remains in the correct position, and can effectively prevent it from falling off or shaking even when subjected to external force.

[0036] like Figures 2 to 5As shown, in the present embodiment, the hinged position of the force arm 2 and the slider 6 is the fixed point A, and the hinged position of the force arm 2 and the supporting arm 3 is the force point B. When the sliding support for the building doors and windows is fully closed, the angle between the line connecting the fixed point and the force point and the horizontal line is an acute angle, that is, the straight line connecting the two rivets of the force arm 2 has an angle a with the horizontal line, 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.

[0037] like Figures 2 to 5 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 between the fulcrum and the fixed point is greater than the distance 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.

[0038] like Figures 1 to 3 As shown, in this embodiment, a clamping block 8 connected to one side of the door and window is provided at the force point, and a supporting protrusion 81 is provided at the bottom of the clamping block 8 close to the door and window. The supporting protrusion 81 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.

[0039] like Figures 1 to 3 As shown, in this embodiment, a force-bearing arm protrusion 21 is provided on the force-bearing arm 2, and the force-bearing point is provided on the force-bearing arm protrusion 21, so that the position of the force-bearing point can be controlled more accurately, and it is also convenient to dock and install with doors and windows or other connecting parts, making the installation process simpler and faster, and improving the accuracy and stability of the installation. In addition, a side of the force-bearing arm 2 away from the clamping block 8 is provided with an avoidance notch 22, so that the force-bearing arm 2 can more flexibly adapt to the movement trajectory of the doors and windows when bearing the weight of the doors and windows, avoiding interference and collision between the force-bearing arm 2 and other components, reducing friction and resistance, and making the operation of the sliding support more stable and efficient.

[0040] like Figures 1 to 3As shown, in this embodiment, the side of the clamping block 8 is provided with a plurality of first threaded holes, and the side top screw fixes the clamping block 8 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 8 is provided with a second threaded hole, and the top top screw is threadedly connected to the clamping block 8 through the second threaded hole. An adjustment rod is provided on the supporting arm 3, and the clamping block 8 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 8 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 8 will be subjected to an upward thrust, and the clamping block 8 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.

[0041] 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.

[0042] 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.
