[0059] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0060] like Figure 1 As shown, this embodiment of the present invention provides a hinge adjustment mechanism for doors and windows, including a frame assembly 100 mounted on a frame profile and a sash assembly 200 mounted on a sash profile. The frame assembly 100 has a rotatable bottom cover 4 to reduce and cover the opening in the profile; furthermore, the frame assembly 100 and the sash assembly 200 can move up and down within a certain range, thereby making the hinge installation position adjustable, improving installation convenience, and reducing installation accuracy.

[0061] The specific structures of the frame component 100 and the sector component 200 are described below:

[0062] (I) Box Components

[0063] In this embodiment, the frame assembly 100 is mounted on the frame profile. For example... Figure 2 As shown, the frame assembly 100 includes a fan rotator 1, a rotator shaft 2, a frame connector 3, a base cover 4, and a bushing 5.

[0064] Specifically, one end of the rotating fan 1 (i.e. Figure 2 The right end of the shaft 2 has a rotating shaft hole 11, and the other end has a connecting hole 12 (three in this embodiment, but not limited to the number of connecting holes 12). The rotating shaft hole 11 is used to cooperate with the rotating shaft 2 and the bushing 5, and the connecting hole 12 is used to cooperate with the fan assembly 200 (described in detail below).

[0065] The rotating shaft 2 passes through the bushing 5, and the bushing 5 passes through the rotating shaft hole 11, with both ends of the rotating shaft 2 protruding out of the rotating shaft hole 11. Preferably, a key 51 is formed on the outer wall of the bushing 5, and a keyway 111 is formed on the inner wall of the rotating shaft hole 11. The key 51 and the keyway 111 engage to limit the relative position of the bushing 5 and the fan rotating component 1.

[0066] There are two frame connectors 3, each connected to one end of the rotating shaft 2 for connection with the frame profile. In this embodiment, the two frame connectors 3 serve two functions: one is to connect with the frame profile as a connector, and the other is to serve as the mounting base for the bottom cover 4. Specifically, as... Figure 2 and Figure 3 As shown, the frame connector 3 is connected and fixed to the frame profile via a threaded plate 301, and the frame connector 3 has a connecting part 31 with a connecting shaft hole 311. One end of the rotating shaft 2 passes through the connecting shaft hole 311, thereby connecting the two frame connectors 3 to the two ends of the rotating shaft 2 respectively.

[0067] Furthermore, the connecting part 31 extends towards the fan rotating component to form a connecting boss 312, and the bottom cover 4 is provided with a rotating latch 41, which is rotatably engaged with the outer wall of the connecting boss 312 around the central axis of the rotating shaft 2, thereby allowing the bottom cover 4 and the fan rotating component 1 to rotate relative to each other (e.g., Figure 4 and Figure 5 (As shown).

[0068] like Figure 3 As shown, in the above embodiment, preferably, a limiting screw hole 32 is provided on the frame connector 3. The central axis of the limiting screw hole 32 is perpendicular to the central axis of the connecting shaft hole 311, and the limiting screw hole 32 is connected to the connecting shaft hole 311. Correspondingly, a limiting groove 21 is provided on the outer wall of one end of the rotating shaft 2 in the circumferential direction. Thus, by threading a limiting bolt 33 into the limiting screw hole 32, as the limiting bolt 33 sinks continuously in the limiting screw hole 32, the bottom of the limiting bolt 33 is eventually locked in the limiting groove 21, thereby limiting the relative position of the frame connector 3 and the rotating shaft 2. It is understood that this structural form is only one preferred embodiment. In other embodiments, other structural forms can also be used to achieve the limiting function, which will not be specifically described here.

[0069] In addition, such as Figure 2 As shown, more preferably, copper sheets 22 and gaskets 23 are provided at both ends of the connecting shaft 2 to improve the connection effect between the connecting shaft 2 and the frame connector 3.

[0070] In addition, such as Figure 2 As shown, a limiting protrusion 42 is formed on the outer wall of the base cover 4. When the base cover 4 rotates to a certain angle, the limiting protrusion 42 will abut against the outer wall of the frame connector 3, thereby limiting the maximum rotation angle of the base cover 4.

[0071] (II) Fan Assembly

[0072] In this embodiment, the fan assembly 200 is mounted on the fan profile. For example... Figure 6 and Figure 7 As shown, the fan assembly 200 includes a clamping bar 6, a locking member 7, a back plate 8, a connector 9, a fan fixing member, and a fan adjusting member.

[0073] Specifically, the clamping strip 6 is connected to the fan profile via a fan fixing component and a fan adjusting component (described in detail below). The fan rotating component 1 and the back plate 8 are respectively installed on both sides of the clamping strip 6 to enable relative movement between the fan rotating component 1 and the clamping strip 6. Specifically, in this embodiment, the surface of the back plate 8 is provided with a strip-shaped hole 81 and a threaded hole 82, and the clamping strip 6 is provided with a strip-shaped groove 61 (three in this embodiment) and a through hole 62. Among them, the strip-shaped hole 81 is aligned with the through hole 62, and the threaded hole 82 is aligned with the strip-shaped groove 61.

[0074] During installation, the locking element 7 passes through the connecting hole 12 and the slot 61 in sequence and connects to the threaded hole 82; meanwhile, the connecting element 9 is movably inserted into the slot 81 and connects to the through hole 62. Thus, when the locking element 7 is tightened, the rotating element 1 and the clamping bar 6 are relatively fixed; when the locking element 7 is loosened, the back plate 8 and the fan rotating element 1 are relatively fixed, and the back plate 8 and the clamping bar 6 are relatively movable, thereby allowing the relative position of the fan rotating element 1 and the clamping bar 6 to be freely adjusted within a certain range (i.e., the range of movement of the slot 61 or the slot 81), thereby achieving adjustment of the overall installation position of the hinge.

[0075] In the above embodiment, preferably, a hanging shaft 63 is formed on the surface of the clamping bar 6, and correspondingly, a groove 13 is formed on the fan rotating component 1 at a position corresponding to the hanging shaft 63. The groove 13 slides with the hanging shaft 63, thereby guiding the movement of the clamping bar 6 and the fan rotating component 1 and ensuring the stability of the movement.

[0076] like Figure 7 As shown, the fan mounting component includes a fan mounting plate 101 and a fan fixing plate 102. The fan mounting plate 101 is mounted on the fan profile by bolts or other connecting components, and the fan fixing plate 102 is mounted on both ends of the clamping strip 6 and connected and fixed to the fan mounting plate 101, thereby mounting the fan assembly 200 as a whole onto the fan profile.

[0077] like Figure 7 As shown, the fan adjustment component includes a fan adjustment base plate 201, an adjustment guide shaft 202, and an adjustment bolt 203. The fan adjustment base plate 201 is located at both ends of the clamping bar 6. The adjustment guide shaft 202 connects the fan adjustment base plate 201, the clamping bar 6, and the fan fixing plate 102. The adjustment bolt 203 is threadedly connected to the clamping bar 6, and its two ends abut against the fan adjustment base plate 201 and the fan fixing plate 102, respectively. Therefore, by rotating the adjustment bolt 203, the distance between the fan profile and the frame profile can be adjusted, thereby achieving adaptive adjustment of the installation position of the fan assembly 200.

[0078] The installation process of the hinge adjustment mechanism according to this utility model embodiment is described in detail below:

[0079] (1) Installation of the frame component

[0080] ① First, fix the threaded plate 301 to the pre-drilled frame profile using Phillips countersunk screws;

[0081] ② Rotate the bottom cover 4 in the direction of door and window opening. After rotation, screw the entire frame assembly into the opening of the frame profile.

[0082] ③ After tightening the fixing bolts, rotate the bottom cover 4 in the opposite direction until it reaches the surface of the frame profile.

[0083] (2) Installation of fan assembly

[0084] ① First, fix the fan mounting plate 101 to the fan profile with pre-drilled holes using Phillips head countersunk screws;

[0085] ②Then, place the entire fan assembly 200 into the opening and tighten the fixing screws.

[0086] (3) Final assembly

[0087] ① First, move the back panel 8 to the top position;

[0088] ② Hook the hanging shaft 63 of the clamping bar 6 in the fan assembly into the groove 13 of the fan rotating part 1. At this time, the connecting hole 12 of the fan rotating part 1, the strip groove 61 of the clamping bar 6 and the threaded hole 82 of the back plate 8 are on the same axis. Finally, tighten the locking part 7.

[0089] In addition, if the installation position needs to be adjusted during the installation process, the locking screws can be loosened first, and the door can be raised with the help of tools; when the desired position is reached, the locking screws can be tightened.

[0090] Based on the above embodiments, this utility model also provides a door and window, which includes the above-mentioned hinge adjustment mechanism.
