Description

Technical Field

[0001] The utility model relates to the technical field of window screens, in particular to a base-free wire-controlled window screen. Background Art

[0002] A window screen is a netting installed on a window, mainly used to prevent small insects such as mosquitoes and flies from entering the room, while maintaining indoor ventilation and lighting. Existing window screens such as the assembled invisible window screen disclosed in the utility model patent with the publication number CN202767852U and the invisible rolling curtain window screen disclosed in the utility model patent with the publication number CN202954727U can all achieve insect prevention, ventilation, and lighting.

[0003] However, it is found during the installation process that when the space at some installation positions is insufficient, there is often no space to install the base frame, resulting in greater installation difficulty. And without the base frame, it is difficult to catch the built-in handle that can be pulled down, resulting in poor practicability. Therefore, there is an urgent need for a base-free wire-controlled window screen to improve the above problems. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a base-free wire-controlled window screen that improves the practicability of the base-free wire-controlled window screen by means of a downward pull shielding mechanism, and at the same time guides the shielding mechanism through a guiding mechanism, so that the shielding mechanism unfolds in the middle of the window frame to shield the middle of the window frame, and then limits the shielding mechanism through a limiting mechanism.

[0005] A base-free wire-controlled window screen of the utility model includes a window frame; it further includes a shielding mechanism, a limiting mechanism, and a guiding mechanism. The shielding mechanism and the limiting mechanism are both installed on the window frame, and the guiding mechanism is installed on the shielding mechanism;

[0006] The window frame fixes the shielding mechanism and the limiting mechanism. The shielding mechanism shields the middle of the window frame, the limiting mechanism limits the shielding mechanism, and the guiding mechanism guides the shielding mechanism;

[0007] By pulling down the shielding mechanism and guiding the shielding mechanism through the guiding mechanism at the same time, the shielding mechanism unfolds in the middle of the window frame to shield the middle of the window frame, and then the shielding mechanism is limited by the limiting mechanism, thereby improving the practicability of the base-free wire-controlled window screen.

[0008] Preferably, the shielding mechanism includes a winding device, a screen mesh, an in-built handle, two sets of sliders and positioning wires. Guide grooves are provided on both the left and right sides of the window frame. The winding device is installed at the top of the window frame. The screen mesh is wound on the winding device. The in-built handle is slidably installed in the guide groove of the window frame, and the top end of the in-built handle is connected to the bottom end of the screen mesh. The two sets of sliders are respectively slidably installed at the left and right ends of the window frame, and limit bolts are provided on both sets of sliders. The end parts of the positioning wires are respectively connected to the outer side walls of the two sets of sliders. The middle part of the positioning wire passes through the interior of the window frame in a surrounding manner, and the positioning wire presses and limits the unfolded screen mesh; by sliding the slider up or down and then tightening the bolt to fix the slider, the length of the positioning wire passing through the interior of the window frame is adjusted to control the pulling-down distance of the in-built handle. Then, by pulling down the in-built handle, the in-built handle slides down along the window frame to unfold the screen mesh, and then the in-built handle is hung on the limiting mechanism. The middle part of the window frame is shielded by the screen mesh, and at the same time, the left and right parts of the screen mesh are pressed by the positioning wire to seal the gap between the screen mesh and the window frame, thereby improving the practicability of the base-free wire-controlled window screen.

[0009] Preferably, the winding device includes a housing, a reel and two sets of disc springs. The housing is installed at the top of the window frame. The reel is rotatably installed in the housing. The two sets of disc springs are both installed on the reel, and the side ends of the two sets of disc springs are fixedly installed on the inner wall of the housing. The screen mesh is wound on the reel; by pulling down the in-built handle, the reel rotates to unfold the screen mesh. When the screen mesh is not in use, the in-built handle is released, and through the resilience of the two sets of disc springs, the reel rotates in the reverse direction to roll up the screen mesh, thereby improving the practicability of the base-free wire-controlled window screen.

[0010] Preferably, the limiting mechanism includes two sets of fixed seats and two sets of limiting shafts. The two sets of fixed seats are respectively installed in the sliding grooves on the left and right parts of the window frame. The two sets of limiting shafts are respectively installed on the two sets of fixed seats; after pulling down the in-built handle to the bottom of the window frame, the bottom of the in-built handle is hung on the two sets of limiting shafts to limit the in-built handle. When the screen mesh is retracted, by pushing the in-built handle backward, the in-built handle is separated from the two sets of limiting shafts, and then the reel rolls up the screen mesh, thereby improving the practicability of the base-free wire-controlled window screen.

[0011] Preferably, the guiding mechanism includes two sets of springs and two sets of rollers. One ends of the two sets of springs are respectively installed on the left and right ends of the in-built handle. The two sets of rollers are respectively rotatably installed on the other ends of the two sets of springs; when the in-built handle slides up and down in the sliding groove of the window frame, due to the elasticity of the two sets of springs, the two sets of rollers roll in the sliding groove of the window frame, thereby improving the smoothness of pulling the in-built handle.

[0012] Preferably, an opening is provided at the bottom of the outer shell, and a cleaning brush is provided on the opening of the outer shell; the screen mesh passes through the opening of the outer shell, and when the built-in handle or the reel is pulled downward to roll up the screen mesh, the surface of the screen mesh is cleaned by the cleaning brush to remove flocs and dust on the screen mesh, thereby improving the practicability of the base-free wire-controlled window screen.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: through the downward pull shielding mechanism, and at the same time, the shielding mechanism is guided by the guiding mechanism, so that the shielding mechanism is unfolded in the middle of the window frame to shield the middle of the window frame, and then the shielding mechanism is limited by the limiting mechanism, thereby improving the practicability of the base-free wire-controlled window screen.
