Detailed Implementation

[0028] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below. The following embodiments are only used to more clearly illustrate the technical solution of this application, and should not be used to limit the protection scope of the present invention.

[0029] In the description of this application, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] This application discloses an adjustable door and window limiting device. (Refer to...) Figures 1-4 The system includes a mounting base 1, a mounting rod 2, a connecting rod 3, a slider 5 located on the mounting base 1, a control component 6, a limiting block 8, and an adjusting component 9. In this embodiment, the mounting base 1 is mounted on the window frame. One end of the mounting rod 2 is equipped with a pivot shaft 1, which connects to the bottom of the window during implementation. The mounting rod 2 is hinged to the mounting base 1 via the pivot shaft 1. A second pivot shaft 2 is mounted at the end of the connecting rod 3, located at the end of the mounting base 1 furthest from the pivot shaft 1. The connecting rod 3 is rotatably connected to the mounting base 1 via the pivot shaft 2. A third pivot shaft 3 is mounted at the other end of the connecting rod 3, rotatably connecting the connecting rod 3 to the mounting rod 2. The third pivot shaft 3 is located at the end of the mounting rod 2 furthest from the pivot shaft 1. When the window is opened, the mounting rod 2 drives the connecting rod 3 to rotate with the opening angle of the window. To facilitate window positioning, the mounting base 1 has a slide rail 4 along its length. The slider 5 is located on the slide rail 4. The control component 6 connects the slider 5 to the mounting rod 2 and the connecting rod 3, allowing the slider 5 to move along the slide rail 4 with the opening angle of the window.

[0031] Reference Figure 1 and Figure 3 The control component 6 includes a control lever 61 and a control lever 62. The end of the control lever 61 is located on the slider 5 near the connecting rod 3, and the other end of the control lever 61 is located on the connecting rod 3. One end of the control lever 62 is located on the slider 5 near the mounting rod 2, and the other end of the control lever 62 is located on the mounting rod 2. Both ends of the control lever 61 and the control lever 62 are equipped with a rotating shaft. The control lever 61 is rotatably connected to the connecting rod 3 and the slider 5 through the rotating shaft. The control lever 62 is rotatably connected to the mounting rod 2 and the slider 5 through rotation. This allows the control levers 61 and 62 to rotate at an angle as the window moves, while simultaneously driving the slider 5 to slide along the length of the slide rail 4.

[0032] Reference Figure 3 and Figure 4 The mounting base 1 has several adjustment holes 7 along its length. The limiting block 8 is located in the adjustment hole 7. The adjustment component 9 is used to drive the limiting block 8 to move up and down. When the limiting block 8 moves up, the protrusion of the limiting block 8 blocks and positions the slider 5. Since the control component 6 connects the slider 5 with the connecting rod 3 and the mounting rod 2, the slider 5 is blocked at this time, and the mounting rod 2 and the connecting rod 3 cannot rotate at an angle, thus positioning the window. When the limiting block 8 moves down, the slider 5 can move on the slide rail 4 without obstruction, and the window can be adjusted to open at an angle.

[0033] Reference Figure 3 and Figure 4 The adjusting component 9 is used to control the up-and-down movement of the limiting block 8 and improve the stability of the limiting block 8 when it moves to the highest or lowest position. The adjusting component 9 includes an adjusting block 91, an adjusting rod 92, and an elastic element 93 disposed at the bottom of the adjusting block 91, which are installed sequentially from top to bottom in the mounting base 1. In this embodiment, the elastic element 93 is a spring. A cavity 10 for loading the adjusting component 9 is provided in the mounting base 1 along the height direction. The adjusting hole 7 communicates with the cavity 10 to facilitate the fixing of the end of the limiting block 8 to the adjusting block 91 and improve the stability of the movement of the limiting block 8. A sliding groove 12 communicating with the cavity 10 is provided in the mounting base 1 along the length direction. In this embodiment, the sliding groove 12 is opened at both ends of the adjusting block 91 to improve the stability of the movement of the adjusting block 91. The upper end of the adjusting rod 92 is provided with a rotating shaft one, and the lower end of the adjusting rod 92 is provided with a rotating shaft two. The adjusting rod 92 is rotatably connected to the mounting base 1 through the rotating shaft two. The side wall of the adjusting block 91 is provided with an adjusting groove 11, and the end of the rotating shaft two away from the adjusting rod 92 is inserted into the adjusting groove 11. When the limiting block 8 is pressed, the spring is compressed, and the adjusting rod 92 rotates at an angle as the limiting block 8 moves down. The upper end of the adjusting rod 92 rotates at an angle as guided by the adjusting groove 11.

[0034] Reference Figure 3 and Figure 4The adjusting groove 11 includes a guide section 111, a sliding section 113, a sliding part 114, a sliding part 115, a sliding part 116, a transition section 117, and a guide section 112 connected in sequence. The end of the guide section 112 away from the transition section 117 is connected to the guide section 111. The guide section 112 and the guide section 111 have opposite inclination directions and their bottom ends intersect, facilitating the positioning of the end of the adjusting rod 92. Both the sliding part 113 and the sliding part 116 are inclined downwards. In this embodiment, the sliding part 114 and the sliding part 115 are arranged in a V-shape, with their lowest point forming the positioning point one for positioning the end of the adjusting rod 92. In this embodiment, the sliding portions 113 and 116 are arranged in a V-shape to facilitate the adjustment rod 92 sliding down to its lowest position. The guide portions 111 and 112 are inclined in a V-shape and also have a second positioning point. The transition portion 117 guides the adjustment rod 92 to move to the sliding portion 116. When the limiting block 8 needs to limit the slider 5, the adjustment block 91 moves upward, causing the upper end of the positioning rod to be positioned at one of the positioning points. When the limiting block 8 retracts to facilitate the sliding of the slider 5, the adjustment block 91 moves downward, causing the upper end of the positioning rod to move to the second positioning point for limiting, thus improving the stability of the limiting block 8 during positioning or retraction. In this embodiment, two sets of elastic elements 93 are provided, located at both ends of the adjustment block 91, improving the stability of the adjustment block 91's movement and facilitating its reset.

[0035] The implementation principle of the adjustable door and window limiting device according to this application embodiment is as follows: This application has several adjustment holes 7, and limiting blocks 8 are installed corresponding to the adjustment holes 7 to facilitate the expansion of the window limiting angle and to position the angle as needed. Pressing the limiting block 8 causes the limiting block 8 to protrude or retract. When the limiting block 8 protrudes, it locks the window; when the limiting block 8 is pressed and retracted, it avoids the slider 5. The limiting device of this application is simple and convenient to operate, and the protrusion of the limiting block 8 positions the slider 5, improving the positioning and locking effect after the window is opened.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
