[0054] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0055] like Figures 1-11 As shown:

[0056] Example 1:

[0057] The casement window includes a window frame 2, a hinge block, and a window sash. The window sash is located inside the window frame 2 and is movable. The window frame 2 is connected to the window sash via a hinge block, allowing the window sash to open and close. A limiting plate 20 is provided on one side of the window frame 2, and one side of the limiting plate 20 is horizontal to the back of the window frame 2. The window sash includes a first piece 7 and a second piece 70, with the second piece 70 located on the back of the first piece 7, making the first piece 7 and the second piece 70 an integral structure. The top and bottom surfaces of the first piece 7 are provided with shafts 71, which pass through the guide rail groove 22, thereby reducing the pressure on the hinge block. The window sash is connected to the guide rail groove 22 of the window frame 2 via shafts 71, and the shafts 71 and the guide rail groove 22 form a tenon-and-groove connection, realizing a structure to prevent the window sash from falling.

[0058] Its shaft 71 and positioning hole 72 are both placed on the top and bottom surfaces of the first block 7. However, the shaft 71 and positioning hole 72 form a symmetrical arrangement. The positioning hole 72 is provided with a guide rod 52 provided by the hinge block. However, the window sash and the hinge block form a connected structure.

[0059] The connection between the shaft 71 and the guide rail groove 22 helps the window sash maintain balance.

[0060] The connection between the positioning hole 72 and the guide rod 52 helps the window sash to form a movable structure;

[0061] The first piece 7 has a handle 73 on the front and a latch 74 on the side. The handle 73 is connected to the latch 74 by a transmission rod, which helps the latch 74 to form a telescopic structure. However, the latch 74 and the lock seat 23 are connected by a through-hole structure to realize the closed state of the window sash.

[0062] The second piece 70 has a groove 75 on one side, and sealant 750 is provided in the groove 75; the window frame 2 adopts the frame of the limiting block, which helps to form a protruding structure on one side of the window frame 2, and the window sash is attached to the wall of the limiting plate 20 with sealant 750, thereby improving the sealing performance of the window sash when closed.

[0063] The bottom and top surfaces of the window frame 2 are provided with chain groove 21 and guide rail groove 22. The chain groove 21 and guide rail groove 22 are adjacent structures. The chain groove 21 is provided with a hinge block. The hinge block is connected to the window sash by a hinge arm 40, thus realizing the movable structure of the window sash.

[0064] The chain groove 21 has multiple first holes 210 on one side; the hinge block includes a base 4 and a hinge arm 40. The base 4 is located in the chain groove 21 and has multiple second holes 42. The first holes 210 and the second holes 42 are opposite to each other and can be connected by screws to form a disassembly and installation structure, thereby improving the stability of the hinge block located in the chain groove 21.

[0065] The hinge arm 40 is located on the top surface of the base 4. The hinge arm 40 has multiple third holes 400. The third holes 400 and the second holes 42 are opposite to each other, which helps the hinge arm 40 to form a connection structure with the base 4. The connection of the hinge arm 40 with screws and support rods helps the hinge arm 40 to form a movable structure.

[0066] The hinge arm 40 is divided into a first arm 5, a second arm 50 and a third arm 51. A guide rod 52 is inserted into a third hole 400 at one end of the first arm 5 and the second arm 50. The third hole 400 at the other end is opposite to the second hole 42 of the base 4. The combination of the first arm 5 and the second arm 50 can be the existing technology. The second arm 50 is connected to the adjustment seat 41 in the base 4. The adjustment seat 41 is a movable structure, which helps the hinge arm 40 to achieve a movable structure.

[0067] The adjusting seat 41 has a hole on one side, which is connected to the third hole 400 of the second arm 50. The connection is made by a screw and a support rod, which helps the second arm 50 to form a movable structure.

[0068] Its adjustment seat 41 is inserted inside the base 4, and the adjustment seat 41 has a sliding structure, which helps the second arm 50 to form a stretching structure, thus realizing the movable structure of the hinge arm 40.

[0069] The window frame 2 has a horizontal structure on one side and the limiting plate 20 on the other side. However, when the window sash is closed, it improves the aesthetics of the combination of the window frame 2 and the window sash.

[0070] Mortise and tenon joints, an existing technology, are characterized by a precise interlocking of protrusions and recesses, which helps improve the balance of the window sash and thus achieves a structure that prevents the window sash from falling off.

[0071] The structure of the inward-opening casement window in this application is used for inward-opening casement windows in bidirectional casement windows.

[0072] Example 2:

[0073] The first hole 210 is equipped with a Ram screw, and the window frame has a hole with a Ram screw inside, which facilitates the disassembly and installation of the screw.

[0074] Example 3:

[0075] The first arm 5 has a fourth hole 52 on one side. The third hole 400 at one end of the third arm 51 is opposite to the fourth hole 52. The third hole 400 at the other end is opposite to the second hole 42 on the base 4. However, the connection between the first arm 5 and the third arm 51 forms a triangular structure, which helps to improve the angle adjustment of the window sash when it is open, and at the same time improves the stability of the window sash when it is open.

[0076] Example 4:

[0077] The positioning rod 6 passes through the second hole 42 and the third hole 400. It is a structure in which the shaft connects to the hole, which helps the first arm 5, the second arm 50, and the third arm 51 to achieve a movable structure.

[0078] One end of the positioning rod 6 is provided with a fixing rod 60, which passes through the interior of the slider nut 30. The fixing rod 60 and the slider nut 30 are connected by threads, which helps the positioning rod 6 to form a fixed structure.

[0079] Example 5:

[0080] The Ram screw includes a nut body 3 and a slider nut 30. Both the nut body 3 and the slider nut 30 are provided with screw holes. The slider nut 30 passes through the nut body 3. When the nut body 3 is placed inside the first hole 210, the slider nut 30 inside the nut body 3 is twisted, and the slider nut 30 forms a structure that moves upward.

[0081] The slider nut 30 is I-shaped. The upward movement of the slider nut 30 is achieved by the nut body 3 being compressed by the slider nut 30 and the handle. Figure 11 As shown, the deformation of the nut body 3 helps the Ram screw and the first hole 210 to form a snap-fit ​​connection structure, thus providing stability for the Ram screw installation;

[0082] Its handle is a screwdriver handle, which is not shown in the picture.

[0083] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
