[0050] In this embodiment, there are two roller units 221, which are respectively arranged at both ends of the anti-slip connecting frame 21; the anti-slip connecting frame 21 is provided with an installation groove 211 for installing the movable pulley 23; the connection point between the rocker arm 12 and the anti-slip connecting frame 21 is the first hinge point, and there are two movable pulleys 23, which are respectively arranged on both sides of the first hinge point.

[0051] As another embodiment of the present invention, the structure of the European standard C-groove drift and drift inward-tilting door and window hardware anti-falling safety system is basically the same as the structure in the above-mentioned embodiment, the difference being that the anti-sinking component 3 includes a first anti-sinking mechanism 31 and a second anti-sinking mechanism 32, wherein the first anti-sinking mechanism 31 is connected to the window frame 4 and abuts against the window sash 5, and the first anti-sinking mechanism 31 is arranged at one end of the window sash 5 for supporting and limiting the window sash 5; the second anti-sinking mechanism 32 is connected to the window frame 4 and abuts against the window sash 5, and the second anti-sinking mechanism 32 is arranged at the other end of the window sash 5 for supporting the window sash 5.

[0052] In this embodiment, the first anti-sinking mechanism 31 includes a first connecting bracket 311 and an anti-sinking roller 312, wherein the first connecting bracket 311 is fixedly connected to the window frame 4 and is arranged on one side of the support seat 11, and a reinforcement for increasing stability is provided between the first connecting bracket 311 and the window frame 4; the anti-sinking roller 312 is rotatably connected to the first connecting bracket 311 and abuts against the top of the window sash 5, thereby realizing the anti-torsion effect of the window sash 5 to a certain extent.

[0053] In this embodiment, the second anti-sinking mechanism 32 includes a second connecting bracket 321, a first support wheel 322, and a second support wheel 323, wherein the second connecting bracket 321 is fixedly connected to the window frame 4 and is arranged on one side of the support seat 11, and the second connecting bracket 321 is an L-shaped structure; the first support wheel 322 is rotatably connected to the second connecting bracket 321 and abuts against the bottom of the window sash 5; the second support wheel 323 is rotatably connected to the second connecting bracket 321 and abuts against the bottom of the window sash 5, and the connecting line between the second support wheel 323 and the first support wheel 322 is a first reference line, and the first reference line is parallel to the slide rail 6.

[0054] As another embodiment of the present invention, the structure of the European standard C-groove drift and drift inward-tilting door and window hardware anti-falling safety system is basically the same as the structure in the above-mentioned embodiment, the difference being that the device also includes a handle 7, a locking assembly 8, and a transmission assembly, wherein the handle 7 is connected to the window sash 5; the locking assembly 8 is simultaneously connected to the window sash 5 and the window frame 4, and is used to control the locking between the window sash 5 and the window frame 4; the transmission assembly 9 is simultaneously connected to the handle 7, the window sash 5 and the locking assembly 8, and is used to control the working state of the locking assembly 8.

[0055] This device can realize a transmission function: the user rotates the handle 7 to drive the movement of the transmission rod and transmission rope in the transmission assembly, thereby realizing the opening and locking functions of the locking point in the locking assembly 8. The transmission is achieved using a European standard transmission rope, and the entire transmission process is carried out within the European standard groove. Defined as the window locked in the initial state, turning the handle 7 upward by 90 degrees, the locking point is unlocked, and the window sash 5 can now drift open like a high-speed rail door. Turning it upward by 180 degrees, the inward locking point is activated, and the window sash 5 can now open only the upper part to the room, i.e., the inward tilt function.

[0056] This device can realize the locking and drifting functions of the window sash 5: locking points are installed on the handle side and back side of the window sash 5, in the European standard grooves where the frame and sash match, respectively, to realize the drifting, inward tilting and locking functions of the window. When the window is opened, the connecting rocker arm 12 rotates 90 degrees, and the window sash 5 drifts out from the window frame 4. Slide rails 6 are laid above and below the window sash 5 and in the corresponding European standard grooves of the window frame 4, so that the hardware installed on the window sash 5 can slide freely along the slide rails 6. When the window sash 5 is pushed and pulled, the window sash 5 slides in the slide rails 6 by moving the pulley 23. The handle 7, locking assembly 8, and transmission assembly are all existing technologies and will not be described in detail here. As long as the relevant performance functions of the above-mentioned handle 7, locking assembly 8, and transmission assembly can be achieved, they are within the scope of protection of this application document.

[0057] In this embodiment, the anti-slip connection frame 21 connected to the window sash 5 is further provided with a boss 24 adapted to fit the window sash 5. Two bosses 24 are provided, one on each side of the anti-slip connection frame 21, for engaging with and supporting the window sash 5. The anti-slip connection frame 21 is provided with a mounting recess 212 for mounting a roller unit 221. The roller unit 221 is disposed between the plane of the boss 24 and the mounting recess 212.

[0058] When the window sash 5 is opened, the lower surface of the window sash 5 automatically overlaps the support wheel assembly of the second anti-sinking mechanism 32 below the window sash 5, and the upper surface of the window sash 5 overlaps the support wheel assembly of the first anti-sinking mechanism 31 above the window sash 5. The window sash 5 can slide out smoothly without the handle end of the window sash 5 sinking. When the movable pulley 23 in the slide rail 6 slides, the anti-slip wheel assembly 22 ensures that the drift anti-slip assembly 2 does not derail, preventing the window sash 5 from derailing and providing safety protection.

[0059] The present invention directly realizes the drift and inward tilting functions on the basis of the original European standard C-notch casement window profile for doors and windows. It has the high air tightness and water tightness of inward-opening windows, the thermal performance characteristics, and the advantage of sliding windows that do not occupy indoor space, and also realizes the inward tilting micro-ventilation function. It reduces the types of profiles on the market, reduces the overall cost of social door and window manufacturing, improves efficiency, and reduces carbon emissions. While realizing the drifting function and inward tilting function of the opening fan, it prevents the handle end of the opening fan from falling and derailing, and provides safety measures and protection.
