It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] This utility model provides the following: Figure 1-3 The internal pulley lifting anti-detachment device shown includes a lock seat body 1 and an anti-detachment component 2, which are integrally formed. The lock seat body 1 and the anti-detachment component 2 are perpendicular to each other and L-shaped. The anti-detachment component 2 is provided with a pulley groove 3 and a circular rod 4 is installed in the pulley groove 3. A pulley top cover 5 is snapped onto the top of the pulley groove 3 on the anti-detachment component 2, and the upper surface of the pulley top cover 5 is flush with the top of the anti-detachment component 2. A roller 6 is sleeved on the circular rod 4 and rotatably connected to it. The roller 6 passes through the pulley top cover 5 and extends above the pulley top cover 5.

[0020] like Figure 1-3 As shown, in this utility model, the locking body 1 is integrally connected to the anti-disengagement component 2 with a positioning abutment 7. The positioning abutment 7 can form a precise abutment with the door and window frame or corresponding component during device installation, effectively limiting the lateral displacement of the locking body 1, further improving the overall installation stability and positional accuracy, and avoiding device displacement due to vibration or external force during long-term use.

[0021] like Figure 1-3 As shown, in this utility model, the lock base body 1 on the side away from the anti-detachment component 2 and the anti-detachment component 2 on the side away from the lock base body 1 are both integrally connected to the mounting base 8. Multiple mounting blocks 9 are integrally connected to one side of the mounting base 8. The mounting blocks 9 increase the contact area between the device and the mounting surface. By using the mounting holes preset on the mounting blocks 9 and fasteners, the device can be firmly fixed to the designated position of the door or window sash or frame, ensuring the structural strength after installation.

[0022] like Figure 1-3 As shown, in this utility model, the lock seat body 1 has a lock seat threaded hole 10 in the middle and the lock seat threaded hole 10 passes through the lock seat body 1. The lock seat body 1 is provided with a lock seat fixing bolt 11 at the lock seat threaded hole 10. After the device is initially positioned, the lock seat fixing bolt 11 is screwed into the lock seat threaded hole 10 and tightened, which can reinforce the lock seat body 1 a second time, so that it is tightly connected with the transmission mechanism or locking system of the door and window, ensuring smooth transmission and reliable locking.

[0023] like Figure 1-3 As shown, the anti-detachment component 2 of this utility model has an anti-detachment threaded hole 12 in the middle and the anti-detachment threaded hole 12 passes through the anti-detachment component 2. An anti-detachment fixing bolt 13 is provided on the anti-detachment component 2 at the anti-detachment threaded hole 12. The anti-detachment fixing bolt 13 cooperates with the anti-detachment threaded hole 12 and is mainly used to strengthen the installation firmness of the anti-detachment component 2 itself and prevent it from loosening or separating from the installation base when subjected to the weight of the window sash or external impact.

[0024] like Figure 1-3 As shown, the anti-detachment component 2 of this utility model has a hollow mounting groove 14 on one side of the pulley groove 3, and the hollow mounting groove 14 passes through the anti-detachment component 2. The hollow mounting groove 14 can be used to install other functional rods or connecting wire harnesses in the door and window system, avoiding additional drilling on the surface of the anti-detachment component 2. This not only ensures the structural integrity of the anti-detachment component 2, but also provides a convenient channel for the arrangement of related components, making the overall structural layout more compact and reasonable.

[0025] When actually assembling the roller 6, first, the roller 6 is placed on the circular rod 4. Then, the two ends of the circular rod 4 are inserted into the pre-set grooves on the inner wall of the pulley groove 3 to ensure that the circular rod 4 is installed in place and can stably support the roller 6, allowing it to rotate flexibly around the circular rod 4. Finally, the pulley top cover 5 is aligned with the slot at the top of the pulley groove 3 and pressed down until the upper surface of the pulley top cover 5 is flush with the top of the anti-detachment component 2, thus completing the encapsulation of the roller 6. This snap-fit ​​design makes the installation and subsequent maintenance and replacement of the roller 6 extremely convenient, without the need for complicated tools.

[0026] Working Principle: In practical implementation, the device is fixed to the designated position of the door / window sash via the mounting base 8 and mounting block 9. During installation, the alignment protrusion 7 abuts against the door / window frame for precise positioning. When the window sash is in the tilt-in / tilt-out state, the roller 6 contacts the guide rail on the window frame and rolls along the guide rail. Through the rotational cooperation of the circular rod 4 and the roller 6, the window sash slides smoothly. Simultaneously, the design of the roller 6 extending above the pulley top cover 5 ensures effective contact with the guide rail at all times, preventing slippage. The lock seat body 1 is connected to the door / window locking system via lock seat fixing bolts 11. During the closing or tilt-in / tilt-out process, the lock seat body 1 cooperates with the corresponding locking point to achieve the locking function. The anti-detachment component 2 is further reinforced by the anti-detachment fixing bolts 13. Combined with the limiting effect of the pulley groove 3 on the roller 6, they together form an anti-detachment protection mechanism to prevent the window sash from falling off due to unexpected circumstances during opening or closing. The hollow mounting slot 14 allows for the installation of transmission rods as needed, ensuring smooth operation of all components in the door and window system. The integrated design of the overall structure effectively enhances the load-bearing capacity and deformation resistance of the device, ensuring stability and safety during long-term use.
