[0037] In this embodiment, as Figure 1 and Figure 2As shown in the figure, a sash window frame for plastic-steel windows includes a plastic-steel window body 1, on which a sash window frame assembly 2 is installed. The sash window frame assembly 2 adopts a splicing design to reduce the gap between it and the building installation groove during installation. The sash window frame assembly 2 includes a first frame 21, a compensation plate 22, a first bolt 23, a second frame 24, and a second bolt 25. The first frame 21 is installed on the plastic-steel window body 1. The compensation plate 22 is inserted into the limit groove of the first frame 21. The compensation plate 22 is connected to the first frame 21 through the first bolt 23. The second frame 24 is inserted into the limit groove of the compensation plate 22. The second frame 24 is connected to the compensation plate 22 through the second bolt 25. By connecting the compensation plate 22 between the first frame 21 and the second frame 24, the usage range of the first frame 21 and the second frame 24 is expanded, thereby shortening the distance between the sash window frame assembly 2 and the building.

[0038] Therefore, when connecting the sash window frame assembly 2 and the building installation groove, if the gap between the sash window frame assembly 2 and the building installation groove is large, the compensation plate 22 is installed between the first frame 21 and the second frame 24. One end of the compensation plate 22 is connected to the first frame 21 through the first bolt 23, and the second frame 24 is connected to the compensation plate 22 through the second bolt 25. Thus, the usage range of the first frame 21 and the second frame 24 becomes larger, shortening the gap between the sash window frame assembly 2 and the installation groove in the building.

[0039] Furthermore, the first frame 21 is processed into a U shape, and through holes for fixing the usage position are opened in the first frame 21. The compensation plate 22 is selectively used according to the usage requirements, and the usage length of the compensation plate 22 can be processed according to the compensation amount between the first frame 21 and the second frame 24. The compensation plate 22 can be connected end to end. Threads are processed on both the first bolt 23 and the second bolt 25.

[0040] In some embodiments, as Figure 1 and Figure 3 shown, a sliding assembly 3 is installed on the plastic-steel window body 1.

By sliding the roller 32 in the slide rail 31, the plastic-steel window body 1 is driven to move in the first frame 21.

[0041] Furthermore, two slide rails 31 are symmetrically distributed on the upper and lower sides of the first frame 21. The roller 32 moves in the chute of the slide rail 31. The connecting piece 33 is used to fix the roller 32 and the plastic-steel window body 1. The design of the roller 32 and the slide rail 31 makes the opening and closing of the plastic-steel window body 1 smoother.

[0042] In some embodiments, such as Figure 1 , Figure 5 and Figure 6 shown, a locking assembly 4 is installed in the plastic-steel window body 1. The locking assembly 4 is used to limit the position of the plastic-steel window body 1 in the first frame 21. The locking assembly 4 includes a cylinder 41, a pull rod 42 and a reset member 43. The cylinder 41 is fixedly connected to the plastic-steel window body 1. The pull rod 42 is sleeved in the cylinder 41. The reset member 43 drives the pull rod 42 to pass through the cylinder 41 and insert into the card slot of the first frame 21, thereby fixing the position of the plastic-steel window body 1 in the first frame 21.

[0043] Furthermore, two cylinders 41 are symmetrically arranged on the plastic-steel window body 1. A cavity is provided in the cylinder 41. The pull rod 42 moves in the vertical direction in the cylinder 41. The arrangement of the reset member 43 facilitates driving the pull rod 42 to automatically reset.

[0044] In some embodiments, such as Figure 6 shown, the reset member 43 includes a retaining ring 431 and an elastic member 432. The retaining ring 431 is fixedly connected to the pull rod 42. The retaining ring 431 is slidably connected in the cavity of the cylinder 41. The elastic member 432 is sleeved on the pull rod 42. The elastic member 432 is located between the retaining ring 431 and the cylinder 41.

[0045] Furthermore, the retaining ring 431 is used to drive the pull rod 42 to move, and the elastic member 432 pushes the retaining ring 431 to drive the pull rod 42 to reset.

[0046] In some embodiments, such as Figure 4 and Figure 5 shown, a bearing frame 241 is fixedly connected to the second frame 24. A shielding plate 242 is fixedly connected in the bearing frame 241. The shielding plate 242 is made of transparent glass.

[0047] Furthermore, the bearing frame 241 is vertically arranged with respect to the second frame 24. The shielding plate 242 functions to transmit light. The bearing frame 241 is arranged parallel to the plastic-steel window body 1.

[0048] In some embodiments, such as Figure 3 shown, the connecting member 33 includes a support rod 331 and a bolt 332. The support rod 331 is rotatably connected to the roller 32 through a bearing. The support rod 331 is connected to the plastic-steel window body 1 through the bolt 332.

[0049] Furthermore, the roller 32 rotates on the support rod 331 through a bearing. An internal threaded hole is machined in the support rod 331. The support rod 331 is inserted into the card slot of the plastic-steel window body 1 and fixed with the bolt 332.

[0050] In some embodiments, such as Figure 1 shown, a protrusion adapted to the limiting groove of the first frame 21 is machined on the second frame 24.

[0051] Furthermore, the second frame 24 and the first frame 21 can be directly connected through the limiting groove and the protrusion.

[0052] In some embodiments, as Figure 2 shown, a clamping plate is machined on one side of the compensation plate 22, and a limiting groove adapted to the clamping plate is machined on the other side of the compensation plate 22.

[0053] Furthermore, the clamping plate machined on one side of the compensation plate 22 can be inserted into the limiting groove of the first frame 21, and the limiting groove on the other side of the compensation plate 22 is also adapted to the protrusion on the second frame 24.

[0054] In some embodiments, as Figure 6 shown, the elastic member 432 is a compression spring.

[0055] Furthermore, the elastic member 432 is designed as a compression spring, which facilitates the elastic member 432 to drive the pull rod 42 to reset and insert into the groove of the first frame 21 through the retaining ring 431.

[0056] In some embodiments, as Figure 1 shown, a push-pull rod 11 is fixedly connected to the plastic-steel window body 1, and the push-pull rod 11 is machined with abrasive patterns.

[0057] Furthermore, the design of the push-pull rod 11 facilitates driving the plastic-steel window body 1 to move in the first frame 21, and the abrasive patterns are machined on the push-pull rod 11 to increase the friction between the hand and the push-pull rod 11.

[0058] The working principle of the present application will be described below with a preferred embodiment:

[0059] When the gap between the casement frame assembly 2 and the building installation groove is too large during the installation process, the compensation plate 22 is installed between the first frame 21 and the second frame 24. The clamping plate of the compensation plate 22 is inserted into the limiting groove of the first frame 21, and the first bolt 23 is used to connect and reinforce the compensation plate 22 and the first frame 21. The protruding end of the second frame 24 is inserted into the limiting groove of the compensation plate 22, and the second bolt 25 is used to connect the second frame 24 and the compensation plate 22. Subsequently, the first frame 21 and the second frame 24 are reinstalled in the building installation groove, thereby reducing the gap between the casement frame assembly 2 and the building installation groove. When opening and closing the plastic-steel window body 1, the pull rod 42 moves in the cylinder 41 and separates from the first frame 21. Subsequently, the plastic-steel window body 1 is horizontally moved by driving the push-pull rod 11. The support rod 331 on the plastic-steel window body 1 drives the roller 32 to move in the chute of the slide rail 31. The friction force during the movement of the plastic-steel window body 1 is reduced through the design of the roller 32 and the slide rail 31, thereby realizing the opening and closing of the plastic-steel window body 1. When the use position of the plastic-steel window body 1 is adjusted appropriately, the external force on the pull rod 42 is removed. Under the action of the elastic member 432, the retaining ring 431 is pushed to drive the pull rod 42 to move, and the pull rod 42 is reinserted into the corresponding groove in the first frame 21, thereby fixing the position of the plastic-steel window body 1 in the first frame 21.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
