[0002] In the building door and window industry, sliding stays are a crucial hardware accessory, widely used to open and close various doors and windows. Traditional sliding stay designs typically employ a relatively simple structure, consisting of basic components such as a base rail, a slider, a load-bearing arm, and a supporting arm. The sliding of the slider allows the door and window to open and close.

[0003] In existing sliding supports, a bottom rail is mounted horizontally on the door and window frames. One end of a load-bearing arm is hinged to the bottom rail, and the other end of the load-bearing arm is hinged to a support arm. The doors and windows are mounted on the support arm to achieve opening and closing of the doors and windows. However, when the doors and windows are opened, the load-bearing arm is subjected to a large pulling force. This can lead to uneven force on the load-bearing arm, causing the load-bearing arm to tilt, resulting in unstable opening and closing of the doors and windows, and may even cause noise and increased wear, shortening the service life of the doors and windows and the sliding supports.

[0004] The above defects need to be solved urgently. Utility Model Content

DETAILED DESCRIPTION

[0033] 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 with reference to 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 intended to limit the present invention.

[0034] like Figure 1 、 Figure 2 As shown, the utility model provides a sliding support for improving force uniformity, comprising a bottom rail 1, a force-bearing arm 2, a supporting arm 3, and a guide arm 4. The bottom rail 1 is used to connect with the door and window frames to ensure the stability and reliability of the sliding support. The bottom rail 1 is hinged to one end of the force-bearing arm 2, and the other end of the force-bearing arm 2 is hinged to the supporting arm 3, and the doors and windows are installed on the supporting arm 3. A slide groove 11 is provided on the bottom rail 1, and a third connecting hole 41 is provided at one end of the guide arm 4. The connecting member 7 passes through the third connecting hole 41 and cooperates with the slide groove 11. The other end of the guide arm 4 is hinged to the supporting arm 3, so that the guide arm 4 can slide in the slide groove 11, and the length direction of the slide groove 11 is parallel to the length direction of the bottom rail 1, so as to facilitate the opening or closing of doors and windows.

[0035] like Figures 2 to 6 As shown, in this embodiment, two clamping assemblies 5 are provided at the bottom of the bottom rail 1. The two clamping assemblies 5 are symmetrically arranged on both sides of the hinge point between the load-bearing arm 2 and the bottom rail 1. That is, a clamping block 51 is provided on both sides of the load-bearing point of the load-bearing arm 2, which can prevent the load-bearing point from being pulled outward, ensure that the load-bearing arm 2 is evenly supported, and improve the uniformity of the force applied to the sliding support. In addition, when the clamping assembly 5 is rotated clockwise to a predetermined angle, the clamping assembly 5 contacts the inner wall of the door and window frame 8 of the building to achieve clamping of the clamping assembly 5, ensuring that the clamping assembly 5 can always be closely attached to the inner wall of the door and window frame during the opening or closing process of the door and window, effectively preventing the load-bearing arm 2 from tilting or shaking due to uneven force. That is, during the opening or closing process of the door and window, due to the presence of the clamping assembly 5, it can be closely attached to the inner wall of the door and window frame 8 of the building, thereby preventing the load-bearing arm 2 from tilting due to uneven force, improving the stability of the sliding support, and ensuring the smooth opening and closing of the door and window. When the clamping assembly 5 rotates counterclockwise to a predetermined angle, the clamping assembly 5 is no longer in contact with the inner wall of the door and window frame 8 of the building, so that the clamping assembly 5 can be loosened, which facilitates the disassembly and maintenance of the bottom rail 1.

[0036] like Figures 4 to 11As shown, in this embodiment, the clamping assembly 5 includes a clamping block 51 and a rivet 52. The clamping block 51 is arranged at the bottom of the bottom rail 1. One end of the rivet 52 passes through the bottom rail 1 and cooperates with the clamping block 51, thereby connecting the clamping block 51 and the rivet 52 together, so that the rivet 52 can drive the clamping block 51 to move, thereby achieving contact between the clamping block 51 and the inner wall of the building door and window frame 8. Specifically, the clamping block 51 includes two oppositely arranged first side surfaces 511 and two oppositely arranged second side surfaces 512. An abutting surface 513 is provided between the first side surfaces 511 and the corresponding second side surfaces 512. The building door and window frame 8 is provided with a mounting groove, and the abutting surface 513 is used to contact the side wall of the mounting groove. When the rivet 52 is rotated clockwise, the rivet 52 drives the clamping block 51 to rotate, so that the abutting surface 513 contacts the installation groove of the building door and window frame 8, thereby achieving the clamping of the clamping assembly 5; when the rivet 52 is rotated counterclockwise, the rivet 52 drives the clamping block 51 to rotate, so that the first side surface 511 is parallel to the length direction of the installation groove of the building door and window frame 8, and the installation groove of the building door and window frame 8 does not contact, thereby achieving the loosening of the clamping assembly 5, so that the clamping assembly 5 can be easily separated from the building door and window frame 8, which provides great convenience for subsequent disassembly or reinstallation.

[0037] like Figure 4 、 Figure 5 As shown, in this embodiment, the distance between the two first side surfaces 511 of the clamping block 51 is smaller than the distance between the two second side surfaces 512 of the clamping block 51. This facilitates the clamping block 51 to be clamped or loosened with the mounting groove of the building door and window frame 8 when the rivet 52 drives the clamping block 51 to rotate. In addition, a clearance notch 514 is provided on the clamping block 51, and the clearance notch 514 is arranged on the side of the second side surface 512 away from the abutment surface 513, so as to avoid other components in the mounting groove of the building door and window frame 8. In addition, both sides of the clamping block 51 near the two first side surfaces 511 are bent downward, providing space for the clamping block 51 to deform, thereby facilitating the clamping block 51 to be clamped in the building door and window frame 8.

[0038] Figures 3 to 5As shown, in this embodiment, a first connection hole 12 is provided on the bottom rail 1, and a second connection hole 515 is provided on the clamping block 51. One end of the rivet 52 passes through the first connection hole 12 and matches with the second connection hole 515. Specifically, the rivet 52 includes a base 521, a connecting portion 522 provided at the bottom of the base 521, and an adjusting portion 523 provided at the bottom of the connecting portion 522. The base 521 and the connecting portion 522 are both provided in the first connection hole 12, and the adjusting portion 523 is provided in the second connection hole 515, which not only ensures the strength of the connection but also provides a stable fulcrum for subsequent operations. By rotating the base 521, the adjusting portion 523 is driven to rotate through the connecting portion 522, and the adjusting portion 523 then drives the clamping block 51 to rotate, thereby achieving the clamping or loosening of the clamping block 51 and the mounting groove of the building door and window frame 8. In addition, the second connecting hole 515 and the adjusting portion 523 are both square, which can more effectively prevent slippage during relative rotation and ensure that the adjusting portion 523 can accurately drive the clamping block 51 to rotate synchronously.

[0039] Figures 1 to 4 As shown, in this embodiment, a gasket 6 is provided between the load-bearing arm 2 and the bottom rail 1 to prevent direct contact between the load-bearing arm 2 and the bottom rail 1, thereby reducing wear between the load-bearing arm 2 and the bottom rail 1 and extending the service life of the sliding support. In addition, a notch is provided in the gasket 6, which corresponds to the rivet 52. The notch can avoid the rivet 52, facilitating the rivet 52 to drive the clamping block 51 to rotate.
