[0047] Embodiment 1

[0048] Refer to Figures 1 - 11 , this embodiment discloses an inward-opening hinge with adjustable sealing, which includes a horizontal frame mounting plate 2, a vertical frame mounting plate 1, a connecting rod assembly 3, a long rocker arm 4, a transmission assembly 6, a window sash connecting piece 7, and a latch assembly 5. The connecting rod assembly 3, the long rocker arm 4, the transmission assembly 6, and the window sash connecting piece 7 in this embodiment can all refer to the prior art.

[0049] Refer to Figures 2 - 4 , the latch assembly 5 includes a latch seat 501 and a latch member 502; the latch seat 501 is horizontally movably arranged on the vertical frame mounting plate 1, and a latch hole 5014 is provided on the latch seat 501; the latch member 502 is arranged at the end of the transmission assembly 6 close to the vertical frame mounting plate 1; an adjusting structure for changing the horizontal position of the latch seat 501 is provided between the vertical frame mounting plate 1 and the latch seat 501. In addition, the vertical frame mounting plate 1 in this embodiment mainly forms a matching relationship with the latch seat 501, so the vertical frame mounting plate 1 and the latch seat 501 can form a latch seat 501 module.

[0050] The adjusting structure of this embodiment includes an adjusting member 10; an adjusting hole 103 extending horizontally is provided on the vertical frame mounting plate 1; the adjusting member 10 is in threaded cooperation with the adjusting hole 103; the latch seat 501 can move horizontally along with the adjusting member 10. As Figure 3 , Figure 4 and Figure 7 shown, the control part of this embodiment is specifically a non-circular tool hole 1001, which is preferably a countersunk hexagon socket head, and a conventional hexagon wrench can be used to control the rotation of the adjusting member 10 to achieve threaded cooperation with the adjusting hole 103; in addition, the control part can also adopt other forms, such as a cross slot, so that the adjusting member 10 can be rotated by a conventional screwdriver.

[0051] In addition, control parts are provided at both ends of the adjusting member 10 in this embodiment, that is, the ends of the adjusting member 10 facing the indoor side and the outdoor side can be rotated and controlled by tools. On the one hand, the adjusting member 10 can be controlled on the indoor side or the outdoor side, which is convenient for adjustment operations; on the other hand, it can be applicable to the assembly methods of left-opening windows and right-opening windows without disassembling parts, which is beneficial to improving the assembly efficiency and adaptability of the hinge.

[0052] Refer to Figures 3 - 5, Further, a first splicing opening is provided on the side of the adjustment hole 103 facing the latch seat 501, and the first splicing opening extends horizontally. A receiving cavity 5013 is provided on the latch seat 501, and a second splicing opening is provided on the side of the receiving cavity 5013 facing the vertical frame mounting plate 1, and the second splicing opening extends horizontally. By providing the first splicing opening on the adjustment hole 103 and the second splicing opening in the receiving cavity 5013, the receiving cavity 5013 and the adjustment hole 103 can be spliced correspondingly, so that the adjusting member 10 can cooperate with the adjustment hole 103 and the receiving cavity 5013 at the same time. And a part of the adjusting member 10 is in threaded cooperation with the adjustment hole 103, and another part of the adjusting member 10 is located in the receiving cavity 5013.

[0053] Further, both ends of the adjusting member 10 are in contact with the end faces of both ends of the receiving cavity 5013. The adjusting member 10 in this embodiment can be a screw, and both ends of the adjusting member 10 are in contact with the end faces of both ends of the receiving cavity 5013, which is beneficial to avoid the situation that the latch seat 501 moves horizontally relative to the adjusting member 10. And the adjustment hole 103 on the vertical frame mounting plate 1 in this embodiment is a threaded semi-hole, as Figures 2 - 4 shown. With such a structure, on the one hand, the threaded cooperation between the adjusting member 10 and the adjustment hole 103 enables the adjusting member 10 to move horizontally, and at the same time, the cooperation between the adjusting member 10 and the receiving cavity 5013 drives the latch seat 501 to move horizontally. The design is ingenious, the number of parts used is small, and the structure is simple and reliable.

[0054] In addition, convex portions 104 are provided on both the upper and lower sides of the adjustment hole 103, and the convex portions 104 and the main body of the vertical frame mounting plate 1 form a guide groove 105. A guide convex block 5012 matching the guide groove 105 is provided on the latch seat 501, and the guide convex block 5012 is located in the guide groove 105 to realize the horizontal movement guiding of the latch seat 501. At the same time, an auxiliary groove 106 is further provided on the vertical frame mounting plate 1 in this embodiment, and the auxiliary groove 106 is located above the adjustment hole 103; an auxiliary convex block 5015 is provided on the latch seat 501, and the auxiliary convex block 5015 is embedded in the auxiliary groove 106, and the auxiliary convex block 5015 is inclinedly matched with the surface of the auxiliary groove 106 far from the main body of the vertical frame mounting plate 1.

[0055] Further, a mating block 5011 protruding towards the vertical frame mounting plate 1 is provided on the latch socket 501. The latch hole 5014 is provided on the mating block 5011, and the auxiliary bump 5015 and the guiding bump 5012 are respectively arranged on the upper and lower sides of the mating block 5011. An avoidance hole 101 is provided on the vertical frame mounting plate 1, which corresponds to the latch hole 5014, and the avoidance hole 101 is located between the auxiliary groove 106 and the adjustment hole 103. The cooperation between the guiding groove 105 and the protruding portion 104 can, on the one hand, prevent the latch socket 501 from coming off, realizing the assembly of the latch socket 501 and the vertical frame mounting plate 1, and on the other hand, guide the movement of the latch socket 501. In addition, the cooperation between the auxiliary groove 106 and the auxiliary bump 5015, especially using the inclined plane structure, is conducive to the assembly and cooperation of the latch socket 501 and the vertical frame mounting plate 1, and of course also has a guiding effect. Further, in this embodiment, the guiding groove 105 and the auxiliary groove 106 are respectively arranged at both ends in the up and down direction of the latch hole 5014, making the force on the latch socket 501 more balanced, and effectively avoiding the situation of the latch socket 501 tilting or swinging after being stressed.

[0056] See Figures 5 - 7 , at this time, the latch member 502 is located at the middle position. See Figures 8 - 9 , rotate the adjusting member 10 to drive the latch socket 501 to move towards the outdoor side. The hinge in this embodiment is an inward-opening and inward-inverting hinge. Therefore, when the latch socket 501 moves towards the outdoor side, the latch member 502 also moves towards the outdoor side, making the seal tighter when the window is closed. Similarly, see Figures 10 - 11 , when the latch socket 501 moves towards the indoor side, the latch member 502 also moves towards the indoor side, making the seal looser when the window is closed.

[0057] Figures 8 - 11 The position of the latch member 502 in [[ ]] does not change. The purpose is to show the direction of the change in the position of the latch socket 501. In the actual locked state, after the latch socket 501 moves towards the outdoor side or the indoor side, the latch member 502 will abut against the inner side wall of the latch hole 5014, and cause a slight movement of the latch member 502 and the transmission assembly 6, thereby realizing the change in the sealing tightness of the window.

[0058] In this embodiment, the adjusting member 10 with a screw structure, the adjusting hole 103 with a half-threaded hole, and the half accommodating cavity 5013 form a clever matching structure that can not only adjust the lateral movement but also drive the latch socket 501 to move. The structure is simple and compact, with fewer components and convenient operation.

[0059] Of course, to realize the lateral movement adjustment of the latch socket 501 on the vertical frame mounting plate 1, in addition to the structure of this embodiment, other methods can also be used. For example, an eccentric pin can be used to drive the latch socket 501 to move, and the lateral adjustment of the latch socket 501 can also be realized to achieve the sealing adjustment of the window.

[0060] The upper end of the vertical frame mounting plate 1 of this embodiment is provided with an upwardly protruding insertion portion 102; at the end of the horizontal frame mounting plate 2 close to the vertical frame mounting plate 1, there are a slot portion 202 and a hook portion 201, and the slot portion 202 is located on the outdoor side of the hook portion 201; in the assembled state, the insertion portion 102 extends into the slot of the horizontal window frame and is inserted into the slot portion 202. As Figure 1 and Figure 4 shown, when installing the hinge, the vertical frame mounting plate 1 can be pushed upward so that the insertion portion 102 is located in the slot of the horizontal window frame and inserted into the slot portion 202, thereby being able to prevent the horizontal frame mounting from disengaging from the notch of the horizontal window frame. At the same time, the limitation between the insertion portion 102 and the hook portion 201 can further improve the reliability of the horizontal frame mounting plate 2.

[0061] Referring to Figures 1 - 4 , a rotatable clamping piece 8 is provided on the vertical frame mounting plate 1, and the clamping piece 8 is located on the side of the vertical frame mounting plate 1 away from the vertical window frame. Specifically, in this embodiment, the clamping piece 8 is riveted to the vertical frame mounting plate 1, and by rotating the clamping piece 8, clamping or loosening with the vertical window frame can be achieved, facilitating the disassembly and assembly of the vertical frame mounting plate 1 and the vertical window frame.

[0062] To further improve the stability of the vertical frame mounting plate 1, it can also be locked by a fixing screw 9. The fixing screw 9 can pass through the clamping piece 8 and then be locked with the window frame profile.

[0063] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Therefore, any modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
