Technical Field
[0001] The utility model relates to the technical field of door and window hinges, in particular to a built-in hinge for a window leaf door. Background Art
[0002] A hinge is a mechanical device used to connect two solid parts and allow them to rotate relative to each other. Hinges can be made of movable components or foldable materials and are often used in doors and windows.
[0003] The existing built-in hinges for window leaves and doors are used by installing a guide rail inside a window frame or door frame, and then connecting the window or door body through its own connecting rod. The connecting rod can drive the slider to move in the guide rail during the rotation of the window or door body, so as to realize the opening and closing of the door and window. However, during use, since the guide rail is always exposed, impurities may adhere to the guide rail and affect the movement performance of the slider, which not only affects the use effect of the hinge, but also causes inconvenience to the user. Therefore, there is an urgent need for a built-in hinge for window leaves and doors to solve the above problems. Utility Model Content

[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:
[0006] A built-in hinge for a window leaf door comprises a guide rail, limit grooves are provided on both side walls of the guide rail, a slider is installed in the guide rail, balls are installed on the contact surfaces between the slider and the limit grooves, two groups of telescopic folding covers are symmetrically installed on both sides of the slider, connecting blocks are fixed at both ends of the telescopic folding covers, a rotating shaft is installed on one side of the upper end of the slider, a connecting rod is installed on the rotating shaft, a connecting hole is provided at one end of the connecting rod, a fastening bolt is provided on one side of the rotating shaft, and protrusions are arranged in an array on the inner bottom wall of the guide rail.
[0007] Preferably, the limiting groove is formed on the guide rail, and the sliding block is slidably connected to the limiting groove.
[0008] Preferably, the balls are rotatably connected to the slider, and a plurality of groups of balls are arranged in an array along the length direction of the slider.
[0009] Preferably, one group of the connecting blocks is fixedly connected to the slide rail, the telescopic folding cover is connected to the connecting blocks via screws, and another group of the connecting blocks is fixed to the inner end of the limiting groove.
[0010] Preferably, the rotating shaft is rotatably connected to the slider, the connecting rod is welded to the rotating shaft, and the connecting hole is formed on the connecting rod.
[0011] Preferably, the limiting protrusion is formed in the guide rail, and the fastening bolt is connected to the slider via threads.
[0012] Preferably, two groups of mounting holes are symmetrically provided at both ends of the guide rail.
[0013] Beneficial technical effects of the utility model:
[0014] The utility model designs a sealing and dustproof mechanism consisting of a connecting block, a telescopic folding cover and a ball bearing. During the use of the hinge, the telescopic folding cover is installed between the slider and the guide rail through the connecting block. During the movement of the slider, the telescopic folding cover is compressed or stretched accordingly, thereby always providing dust protection for the guide rail. At the same time, the ball bearing is used to convert the original sliding friction into rolling friction, thereby effectively reducing the friction between the two, effectively ensuring the smoothness of the movement of the slider, and ensuring the use effect of the hinge and user experience.

[0021] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.
[0022] like Figure 1-Figure 4As shown, the present embodiment provides a built-in hinge for a window leaf door, comprising a guide rail 1, with limit grooves 9 provided on both side walls of the guide rail 1, a slider 5 installed in the guide rail 1, a ball bearing 12 installed on the contact surface between the slider 5 and the limit groove 9, two groups of telescopic folding covers 4 symmetrically installed on both sides of the slider 5, connecting blocks 3 fixed at both ends of the telescopic folding covers 4, a rotating shaft 11 installed on one side of the upper end of the slider 5, a connecting rod 6 installed on the rotating shaft 11, a connecting hole 7 provided at one end of the connecting rod 6, a fastening bolt 2 provided on one side of the rotating shaft 11, and protrusions arranged in an array on the inner bottom wall of the guide rail 1.
[0023] The limiting groove 9 is formed on the guide rail 1 , and the slider 5 is slidably connected to the limiting groove 9 , and the limiting groove 9 limits the movement of the slider 5 .
[0024] The balls 12 are rotatably connected to the slider 5 , and a plurality of groups of balls 12 are arranged in an array along the length direction of the slider 5 . The balls 12 convert the original sliding friction into rolling friction, thereby effectively reducing the friction between the two, and can effectively ensure the smooth movement of the slider 5 .
[0025] One group of connecting blocks 3 is fixedly connected to the slide rail, the telescopic folding cover 4 is connected to the connecting blocks 3 by screws, and the other group of connecting blocks 3 is fixed at the inner end of the limiting groove 9. During the use of the hinge, the telescopic folding cover 4 is installed between the slider 5 and the slide rail through the connecting block 3. During the movement of the slider 5, the telescopic folding cover 4 is also compressed or stretched, thereby always providing dust protection for the inside of the guide rail 1.
[0026] The rotating shaft 11 is rotatably connected to the slider 5, the connecting rod 6 is welded to the rotating shaft 11, and a connecting hole 7 is formed on the connecting rod 6. One end of the connecting rod 6 can be connected to the window through the connecting hole 7. When the window is opened, the connecting rod 6 rotates under the action of the rotating shaft 11.
[0027] The limiting protrusion 10 is formed in the guide rail 1, and the fastening bolt 2 is connected to the slider 5 through a thread. The fastening bolt 2 and the limiting protrusion 10 are combined to fix the opening angle of the window.
[0028] Two groups of mounting holes 8 are symmetrically provided at both ends of the guide rail 1 , and the mounting holes 8 facilitate the installation of the guide rail 1 in the window frame.
[0029] Working principle of the device: During the use of the device, the guide rail 1 is fixed inside the window frame through the mounting hole 8, and then one end of the connecting rod 6 is connected to the window through the connecting hole 7, thereby connecting the window to the window frame. During the window opening process, the connecting rod 6 rotates under the action of the rotating shaft 11, and at the same time drives the slider 5 to move in the guide rail 1. During the movement of the slider 5, the telescopic folding cover 4 is also compressed or stretched, thereby always providing dust protection for the inside of the guide rail 1. At the same time, the ball bearing 12 is used to convert the original sliding friction into rolling friction, thereby effectively reducing the friction between the two, and effectively ensuring the smoothness of the movement of the slider 5. After the opening is completed, the opening angle of the window is fixed by combining the fastening bolt 2 with the limiting protrusion 10.
