Wherein, the plug-in slot 61 should be understood in a broad sense, no matter whether its slot profile is C-shaped, T-shaped or other shapes, as long as the plug-in block 62 can be plug-in fit with it along the plug-in direction and the separation of the two in the vertical direction is limited.

[0022] During the production of doors and windows, the installation arm 3 can be fixed with the side of the window sash in advance, and the sliding rail 1 can be fixed with the inner side of the window frame. During installation, the installer only needs to install and fit the installation arm 3 with the sliding block 2 through the plug-in buckle structure 6, and install and fit the sliding rail 1 or the installation arm 3 with the connecting rod 4 through the detachable connection structure 5, so as to complete the installation and fixation of the window sash, reduce the installation difficulty and risk, and improve the installation efficiency. The plug-in buckle structure 6 is fitted with the plug-in block 62 and the plug-in slot 61, and is limited vertically through the limiting edges 64 and limited in the plug-in direction through the limiting assembly 63, so that the combination area between the plug-in buckle and the sliding block 2 is large and the combination strength is high; the plug-in block 62 and the plug-in slot 61 are arranged along the length direction of the sliding block 2, so that the plug-in block 62 and the sliding block 2 have sufficient contact area along the length direction to resist the weight of the window sash, and the bearing capacity is strong; during installation, only plug-in is needed, and the alignment and assembly operation is simple.

[0023] In a preferred embodiment, the limiting assembly 63 comprises a front stop 631 protruding from the front end of the slot 61 to limit the forward movement of the plug 62, an elastic piece 632 mounted on the sliding block 2 and extending rearward of the slot 61, and a rear stop 633 protruding from the elastic piece 632. When the plug 62 is inserted into the slot 61 and the front end abuts against the front stop 631, the elastic piece 632 is reset so that the rear stop 633 abuts against the rear end of the plug 62. After the plug 62 is inserted into the slot 61 and abuts against the front stop 631, the rear stop 633 is automatically lifted by the elastic piece 632 to limit the rear end, thus further simplifying the assembly operation. In other embodiments, the limiting assembly 63 can not comprise the front stop 631 and the rear stop 633, but a protruding column of elastic structure, and a matching recess hole on the plug 62. The plug 62 is locked in the slot 61 by inserting the protruding column into the recess hole.

Alternatively, the limiting assembly 63 can be of non-elastic structure, such as comprising a pressing plate arranged between the two sides of the slot 61, one end of the pressing plate is hinged to one side of the slot 61 and the other end is buckled and fixed to the other side of the slot 61, and the protruding column is fixed to the bottom surface of the pressing plate to be vertically inserted into the recess hole of the plug 62 to form a manual locking structure. These structures can all lock the plug 62 in the slot 61 and prevent the plug 62 from being pulled out along the plug-in direction.

[0024] In a preferred embodiment, the front end of the elastic piece 632 is provided with an integral fixing piece 634 fixed to the bottom surface of the slot 61 along the length direction, and the front stop 631 is protrudingly formed on the fixing piece 634. The fixing piece 634 not only strengthens the mounting of the elastic piece 632, but also enables the front stop 631 and the rear stop 633 to be integrally formed, thus improving the forward and rearward limiting strength of the plug 62.

[0025] In a preferred embodiment, the rear end of the elastic piece 632 is integrally formed with a locking piece 635 bent downward to approach or abut against the surface of the sliding rail 1. When the locking piece 635 abuts against the surface of the sliding rail 1, the plug 62 cannot be pulled out of the rear stop 633, and the sliding rail 1 is provided with an unlocking hole 65 corresponding to the sliding track of the locking piece 635 for the locking piece 635 to be pressed downward. When the plug 62 is inserted into or pulled out of the slot 61, the sliding block 2 can only be slid to the position where the locking piece 635 is aligned with the unlocking hole 65, otherwise the elastic piece 632 cannot be deformed enough, thus avoiding accidental unlocking and improving the safety.

[0026] In a preferred embodiment, the slide rail 1 has a recessed groove 11 arranged along its length and adapted to the window frame groove. The slider 2 has a protruding ridge 21 adapted to the recessed groove 11. The locking piece 635 corresponds to the position of the recessed groove 11 and extends downward into the recessed groove 11, while the unlocking hole 65 is located on the bottom surface of the recessed groove 11. The recessed groove 11 not only strengthens the connection between the slide rail 1 and the window frame but also provides sufficient deformation space for the elastic piece 632.

[0027] In a preferred embodiment, one end of the slider 2 is further fixed with a plastic adjusting block 22 that is slidably adapted to the slide rail 1. The adjusting block 22 has an adjusting hole 221 along the sliding direction, and an adjusting screw 222 is fitted inside the adjusting hole 221 to force the adjusting block 22 to expand to both sides to adjust the sliding friction between it and the slide rail 1. By simply rotating the adjusting screw 222, the sliding friction between the slider 2 and the slide rail 1 can be indirectly adjusted.

[0028] In a preferred embodiment, a positioning screw 23 is vertically fitted on the limiting edge 64 of the slot 61, and the side of the insert 62 has a notch 231 adapted to the positioning screw 23. The positioning screw 23 can further improve the fit between the insert 62 and the slot 61, while avoiding mis-locking.

[0029] In a preferred embodiment, the detachable connection structure 5 includes a cylindrical insertion post 51 vertically fixed to the connecting rod 4, and the insertion post 51 has a circumferential limiting groove 511. A U-shaped retaining spring 52 is embedded inside the mounting arm 3, and a locking hole 53 penetrating the middle of the U-shaped retaining spring 52 is provided. The insertion post 51 can be adapted to pass into the locking hole 53, so that both sides of the U-shaped retaining spring 52 are clamped within the limiting groove 511. This not only prevents the insertion post 51 from coming out, but also allows the connecting rod 4 and the mounting arm 3 to rotate relative to each other. In other embodiments, other methods can be used to achieve the post-installation connection between the connecting rod 4 and the mounting arm 3. For example, a vertical threaded hole can be provided at the top of the insertion post 51, and after the insertion post 51 passes through the hole in the mounting arm 3, a T-head screw can be locked into the threaded hole; or a structure similar to the snap-fit ​​structure 6 can be used.
