Description

Technical Field

[0001] The invention relates to the technical field of building supplies, in particular to an outward opening angle regulating device for an outward opening window with built-in hardware. Background Art

[0002] An outward-opening window is a casement window that partially or completely protrudes outside the room after the window sash is opened, that is, a window with window sashes that opens outwards. When the window sash is opened, it protrudes beyond the outer wall. The window sash of an outward-opening window is located outdoors and does not occupy indoor space, nor does it affect the use of indoor curtains or furniture such as lifting hangers. For small apartments or rooms with limited space, outward-opening windows can maximize the use of indoor space. At the same time, the window sashes can be fully opened to allow for smoother indoor and outdoor air circulation, which helps to achieve a greater degree of natural ventilation.

[0003] At present, when the built-in outward-opening windows on the market are in use, the window sashes lack the restriction of positioning components when they are opened, which makes the window sashes rotate when exposed to strong winds. At the same time, the gap between the window sash and the window frame cannot be completely closed, so that foreign matter and dirt will penetrate through the gap between the window sash and the window frame, making it impossible for the existing built-in outward-opening windows to position the window sashes and strengthen the sealing of the window sashes and window frames when in use. Therefore, a device is needed to improve the above-mentioned problems. Summary of the invention

An extension bracket is symmetrically fixedly installed on the right side of the window frame 19, and the second gear 25 and the third gear 28 are respectively mounted on the extension bracket. The end of the extension plate 18 away from the positioning cavity 14 is arranged in an arc state.

[0026] The working principle of embodiment 1 is as follows: when in use, the window frame 19 is first installed in the hole reserved on the wall. Then, when the window 4 needs to be opened outward, the electric push rod 29 can be opened, and the connection in the electric push rod 29 is connected to the synchronization rod 26, so that when the electric push rod 29 is started, the synchronization rod 26 can be driven to move to the rear end, so that the second rack 27 can be disengaged from the first gear 5. At this time, the first gear 5 can be unlocked, and the user can rotate the window 4 outward, so that the window 4 can be separated from the window frame 19, and the action of opening the window 4 is completed. At the same time, when the window 4 is opened outward, the first gear 5 and the second gear 25 can be driven to rotate, and when the second gear 25 rotates, the third gear 28 and the support 21 can be driven to rotate outward at the same time, so that the window 4 is opened. At the same time as the window 4 is opened, the pillar 21 can rotate toward the end away from the window frame 19, so that the pillar 21 can avoid interfering with the window 4. Subsequently, when the window 4 is rotated to a specified angle, the electric push rod 29 can be opened again, so that the synchronization rod 26 can move toward the front end, so that the second rack 27 can mesh with the first gear 5, thereby preventing the window 4 from rotating again. Subsequently, when the window 4 needs to be closed, the above steps can be repeated, so that the second rack 27 can be disengaged from the first gear 5, thereby unlocking the first gear 5, and then the window 4 is rotated toward the inside of the window frame 19. When the window 4 is rotated to contact with the contact strip 9, the contact strip 9 can be squeezed into the inside of the storage cavity 10. At the same time, when the contact strip 9 moves toward the inside of the storage cavity 10, it can drive the extension side rod 12 The first rack 13 moves to the rear end, and the side rod 12 is extended to slide inside the first movable groove 32, so that the first rack 13 can be supported to move in a straight line, and when the first rack 13 moves to the rear end, the fourth gear 36 can be driven to rotate. When the fourth gear 36 rotates, the winding wheel 34 can be driven to wind up the connecting rope 31, so that the connecting rope 31 can pull the displacement support plate 16 to move toward the end away from the positioning cavity 14, so that the first covering plate 17 is displaced toward the end close to the window 4. At the same time, when the first covering plate 17 is displaced, the extension plate 18 can be driven to move to contact with the second covering plate 24, so that the second covering plate 24 can be squeezed to move toward the inner center of the window frame 19, and the second covering plate 24 is connected to the spring inside the connecting cavity 23, so that the first covering plate 17 can be displaced to the inner center of the window frame 19. When the second cover plate 24 is not subjected to pressure, the spring can drive the second cover plate 24 to enter the interior of the connecting cavity 23, so as to avoid interference between the window 4 and the second cover plate 24 when the window 4 rotates. Subsequently, when the window 4 squeezes the contact strip 9 and completely enters the interior of the storage cavity 10, the first cover plate 17 and the second cover plate 24 can be driven to move to the limit position, so that the first cover plate 17 and the second cover plate 24 can respectively cover the front end gaps on the upper and lower sides and the left side of the window 4 and the window frame 19, thereby improving the sealing performance of the window 4 and the window frame 19. Subsequently, when the window 4 is opened, the window 4 can be driven away from the contact strip 9, and the elasticity of the first spring 11 can drive the contact strip 9 to reset to the front end. Moreover, when the window 4 has not yet rotated out of the interior of the window frame 19, the contact strip 9 can return to its original position.When the contact strip 9 is reset, the extension side bar 12 can be reset at the same time, and when the extension side bar 12 is reset, the first rack 13 can be driven to move in the opposite direction at the side end of the fourth gear 36, so that the connecting rope 31 can be released. At this time, the elasticity of the second spring 15 can drive the first cover plate 17 to reset, and when the first cover plate 17 is reset to the inside of the positioning cavity 14, the extension plate 18 can be disengaged from the second cover plate 24, so that the second cover plate 24 can lose the extrusion force, and the spring inside the connecting cavity 23 can drive the second cover plate 24 to reset to the inside of the connecting cavity 23. When the second cover plate 24 and the first cover plate 17 are reset, the end of the second cover plate 24 away from the connecting cavity 23 can be flush with the top and bottom ends of the window frame 19, and the side end of the first cover plate 17 close to the extension plate 18 can be flush with the left side of the window frame 19, so that the window 4 can be smoothly rotated outward to complete the work. Example 2

[0027] On the basis of Example 1, Fig.10 As shown, the positioning cavity 14 further includes a limiting frame 37 and a rain sensor 38 . The limiting frame 37 is fixedly mounted on the front top of the positioning cavity 14 , and the rain sensor 38 is slidably mounted inside the right side of the limiting frame 37 .

[0028] When implementing this embodiment, there is a wireless signal connection between the rain sensor 38 and the mobile phone. When the rain sensor 38 senses rain, it can send a signal to the mobile phone, thereby reminding the user that it is raining. At the same time, when the rain sensor 38 needs to be replaced or repaired, a magnetic sheet is fixedly installed on the side end of the rain sensor 38 close to the limiting frame 37, and an iron plate is installed inside the limiting frame 37. The rain sensor 38 can be directly pulled out from the inside of the limiting frame 37 to complete the disassembly of the rain sensor 38. Subsequently, when the rain sensor 38 needs to be installed, the rain sensor 38 can be inserted into the inside of the limiting frame 37 until the magnetic sheet on the rain sensor 38 is adsorbed and fits with the iron plate inside the limiting frame 37, so that the rain sensor 38 can be supported to be installed inside the limiting frame 37 to complete the work.
