[0003] Multi-locking point sealing can greatly enhance the sealing of the window. After the sealing is enhanced, its thermal insulation and sound insulation will also be improved. The upper pulley assembly is responsible for the connection and sliding of the upper part of the window frame in the window control system.

DETAILED DESCRIPTION

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] As described in the background technology, the device is likely to cause the window to loosen and not be tight during use, and the sealing performance is insufficient. For this reason, the present embodiment provides a fine-tunable anti-sway upper pulley assembly, which can greatly improve the sealing and sound insulation of doors and windows when closed, and can also prevent the doors and windows from loosening and shaking, thereby greatly improving the practicality of the overall device.

[0024] See also Figure 1 - Figure 4The present embodiment proposes a fine-tunable anti-sway upper pulley assembly, including an inner shell 1, a fine-tuning mechanism 2 is provided on the upper surface of the inner shell 1, the fine-tuning mechanism 2 includes a clamping plate 201 fixedly connected to the upper surface of the inner shell 1, an adjusting screw 202 is clamped on a reserved hole on the outer surface of the clamping plate 201, a pull plate 203 is placed on the upper surface of the inner shell 1, and a nut at the output end of the adjusting screw 202 is fixedly connected to the reserved hole on the outer surface of the pull plate 203.

[0025] refer to Figure 4 The setting of the adjusting screw 202 can drive the pull plate 203 to move horizontally more stably by rotating the adjusting screw 202, and the adjusting screw 202 is limited by the clamping plate 201, and then the pull plate 203 will synchronously pull the deflection plate 206 to move during the movement, and fine-tuning can be performed through the mutual cooperation of subsequent components. The setting of the first limiting groove 204 can limit the installation of subsequent components, so that the deflection plate 206 can move smoothly on the pull plate 203.

[0026] The two groups of reserved holes on the outer surface of the inner shell 1 are hinged with a second connecting rod 3, and the outer surface of the second connecting rod 3 is installed and connected with the outer shell 4. An integrated transmission rod 5 is provided inside the outer shell 4, and the integrated transmission rod 5 is located between the side surfaces of the inner shell 1 and the outer shell 4 that are close to each other. By providing the outer shell 4 and the integrated transmission rod 5, the overall device can be better installed at the window sash, thereby facilitating the adjustment and use of the window sash and the window frame, and also facilitating the installation and disassembly of the overall device.

[0027] Two mounting protrusions 6 are provided on the bottom surface of the shell 4, and the mounting protrusions 6 are designed with inclined chamfers and holes are provided on the upper surface of the mounting protrusions 6. By providing the mounting protrusions 6, it can be better installed on the door frame by bolts or screws, thereby facilitating the disassembly and installation of the entire device.

[0028] The upper surfaces of the convex plates at the left and right ends of the integrated transmission rod 5 are provided with mounting holes 7. By setting the mounting holes 7, the window sashes can be fixed and movably inserted into the outer shell 4, thereby further improving the stability of the device after installation and avoiding the situation where a single connecting component is damaged and the device cannot be used.

[0029] A first limiting groove 204 and two double sliding grooves 205 are provided on the upper surface of the pull plate 203, a deflection plate 206 is provided on the upper surface of the pull plate 203, and a guide rod 207 is fixedly connected to the bottom surface of the deflection plate 206, and the guide rod 207 is slidably connected to the first limiting groove 204, a first connecting hole 208 is provided on the upper surface of the inner shell 1, and a first connecting rod 209 is installed on the reserved hole on the upper surface of the deflection plate 206, and the first connecting rod 209 slides through the first limiting groove 204 and is rotatably connected to the first connecting hole 208.

[0030] refer to Figure 4 The setting of the first connecting rod 209 can limit the rotation of the deflection plate 206, so that when the pull plate 203 drives the deflection plate 206 to move, the deflection plate 206 is limited by the first limiting groove 204, the double sliding groove 205 and the first connecting rod 209 to be tilted and twisted, so that the deflection wheel 2010 can fit tightly with the track in the window frame, greatly improving the sealing between the window sash and the window frame when closing.

[0031] The upper surface of the deflection plate 206 is rotatably connected to two deflection wheels 2010, and both deflection wheels 2010 are made of flexible material. By setting the deflection wheels 2010 and the flexible material used by the deflection wheels 2010, the sealing of doors and windows can be further improved, making the window body tighter, and greatly improving the sealing and stability between the window sash and the window frame.

[0032] Two curved guide grooves 8 are provided on the upper surface of the integrated transmission rod 5, and two second limit grooves 9 are provided on the bottom surface of the outer shell 4, and the second limit grooves 9 are located at the lower part of the curved guide grooves 8. By setting the curved guide grooves 8 and the second limit grooves 9, the entire device can be connected by installing bolts or screws of your choice, and fine-tuning operations can be performed through the second limit grooves 9, so that the inner shell 1 can be slightly moved in the outer shell 4.

[0033] Two second connection holes 10 are provided on the upper surface of the inner shell 1, and the second connection holes 10 are located above the curved guide groove 8 and the second limit groove 9. By providing the second connection holes 10, multiple components can be connected to avoid displacement and falling off during use, thereby greatly improving the safety of the overall device.

[0034] Working principle: The whole device is installed on the window sash and window frame by installing the convex plate 6 and the mounting hole 7. When fine-tuning is required, the pull plate 203 is forced to move horizontally by screwing the adjusting screw 202. Since the pull plate 203 and the deflection plate 206 are rotatably fixed on the pull plate 203 by the first connecting rod 209, the deflection wheel 2010 on the deflection plate 206 will also be forced to move horizontally, and the deflection wheel 2010 is tightly attached to the window frame track. The reaction force of the window frame track will be transmitted to the deflection plate 206, and the deflection plate 206 will rotate on the double slide groove 205 of the pull plate 203 with the first connecting rod 209 as the center point, and the maximum rotation range must be within the distance range of X, so that the fine-tuning component obtains more lateral pressure. Therefore, by screwing the adjusting screw 202, the upper pulley assembly can obtain a tighter pressure, so that the window body can be installed more tightly and the sealing performance is better.
