As shown in fig. 4, in a preferred embodiment, a groove 037 is formed on the position limiting member 035 along the length direction thereof, an opening 038 is formed at one end or both ends of the groove 037, the opening 038 is connected to the groove 037, and the width of the opening 038 gradually increases towards a position away from the groove 037, that is, the opening 038 is trumpet-shaped; further, when the locking mechanism 004 performs a locking action, the limiting column 036 enters the groove 037 through the opening 038, and at this time, the trumpet-shaped opening 038 can guide the movement of the limiting column 036, so that the limiting column 036 can more easily move into the groove 037 on the limiting member 035; that is, the flared opening 038 can make the relative movement between the position-limiting member 035 and the position-limiting post 036 less precise, i.e., easier to achieve the locking action of the locking mechanism 004.

In a preferred embodiment, when the first connecting seat 001 and the second connecting seat 002 are folded, the third hinge position 026, the fourth hinge position 027 and the fifth hinge position 028 form an obtuse triangle; further, two corner points of the obtuse triangle are both located on the first connecting seat 001, and when the triangle needs to be changed (at this time, the window sash 048 and the window frame 047 are in a closed state), only the third hinge position 026 (the fifth through hole 014 and the eighth through hole 017 on the second connecting rod 006 and the third connecting rod 007 are respectively connected, or the third hinge position 026 is a corner point of the triangle) can be moved, or the third connecting rod 007 is rotated to change the corner point. Furthermore, an obtuse triangle is enclosed by the second hinge position 025, the first hinge position 024 and the sixth hinge position 029; when the triangle needs to be changed, only the first hinge position 024 (corner point) can be moved, that is, only the first connecting rod 005 can be rotated, and when the position of the first hinge position 024 (corner point) changes, the third connecting rod 007 is synchronously driven to move through the fourth connecting rod 008, so that the position of the third hinge position 026 (corner point) is changed. That is, when the upper hinge 050 is in a folded state, the two triangles on the upper hinge 050 are interlocked, so that the stability of the folded structure of the upper hinge 050 is ensured, and further, the window sash 048 in the closed state can bear positive wind pressure or negative wind pressure from the outside, namely, the relative tightness of the window sash 048 with respect to the window frame 047 is maintained.

As shown in fig. 3, in a preferred embodiment, the second link 006 and the fourth link 008 are both clamped between the first link 005 and the third link 007, the second link 006 and the fourth link 008 are located on the same plane, a recess 039 is further disposed on one side of the second link 006 in the width direction, and when the first connecting seat 001 and the second connecting seat 002 are in the folded state, the fourth link 008 is placed in the recess 039. Further, the fourth hinge location 027 connecting the second link 006 and the second connecting seat 002 is constrained by the thirteenth through hole 022, and the depression 039 (toward the indoor side) on the second link 006 accommodates the fourth link 008 at this time, so as to constrain and block the sixth hinge location 029 formed by hinging the ninth through hole 018 and the eleventh through hole 020 through the pin shaft, and cannot move to the outdoor direction, thereby further improving the stability of the folded structure of the upper hinge 050; secondly, the second link 006 and the fourth link 008 are both clamped between the first link 005 and the third link 007, and the second link 006 and the fourth link 008 are on the same plane, so that the structure of the upper hinge 050 after being stored is relatively more compact.

Further, in a preferred embodiment, a central connection line between the twelfth through hole 021 and the thirteenth through hole 022 is taken as a reference line, when the first connecting seat 001 and the second connecting seat 002 are in the folded state, the third hinge position 026 is located on a first side of the reference line, and when the first connecting seat 001 is unfolded more than 10 degrees to the first side relative to the second connecting seat 002, the third hinge position 026 moves to a second side of the reference line. Specifically, the third hinge point 026, the fourth hinge point 027 and the fifth hinge point 028 enclose a triangle, when the triangle needs to be changed, the fifth hinge point 028 is fixed as an angular point of the triangle, and the fourth hinge point 027 can move relative to the thirteenth through hole 022 (a bar-shaped hole), so that the triangle can be changed by moving the third hinge point 026 (the fourth hinge point 027 moves synchronously with the third hinge point 027 when the triangle needs to be changed). Further, the third hinge position 026 moves to the second side of the reference line when the first connection holder 001 is unfolded more than 10 degrees to the first side with respect to the second connection holder 002, that is, the sixth hinge position 029 is restricted from moving in the indoor direction in the folded state of the upper hinge 050, that is, the second link 006, the third link 007, and the fourth link 008 are engaged with each other and form self-locking. So that the sash 048 in the closed state can withstand either positive or negative wind pressure from the outside, i.e., maintain the relative tightness of the sash 048 with respect to the frame 047.

As shown in fig. 3-5, in the preferred embodiment, the first through-hole 010 is hinged to the fourth through-hole 013 by the second hinge axis 040 and forms a second hinge position 025; further, the second hinge shaft 040 includes a first shaft body 041 and a second shaft body 042, the first shaft body 041 is integrally molded with the second shaft body 042, and the axis of the first shaft body 041 is offset from the axis of the second shaft body 042, and the second hinge shaft 040 is rotatable with respect to the first link 005 and the second link 006. Since the axis of the first shaft 041 is offset from the axis of the second shaft 042, that is, when the hinge shaft 040 is rotationally adjusted, the position of the first shaft 041 relative to the second shaft 042 is changed, so that one end of the first link 005 is changed relative to the second link 006, and the tightness (or the pressing force acting on the sealing strip between the window sash 047 and the window sash 048) is finely adjusted after the window sash 048 and the window sash 047 are closed.

As shown in fig. 4, in a preferred embodiment, the second connection socket 002 includes a first substrate 043 and a second substrate 044, the first substrate 043 and the second substrate 044 are stacked and fixed with respect to a thickness direction of the first substrate 043 or the second substrate 044, and/or the first substrate 043 and the second substrate 044 are integrally formed, the twelfth through hole 021 and the thirteenth through hole 022 both penetrate through the first substrate 043 or the second substrate 044, and a width of the first substrate 043 is smaller than a width of the second substrate 044. Specifically, after the upper hinge 050 is installed on a window, when the width of the first substrate 043 is smaller than that of the second substrate 044, the first substrate 043 may be sunk in the C-shaped groove opening of the window sash 048 profile, and then when the structural strength of the second connection seat 002 is ensured, the occupation of the upper hinge 050 on the installation space between the window sash 048 and the window frame 047 is also reduced.

As shown in fig. 4, in a preferred embodiment, the second connecting socket 002 further includes a first reinforcing plate 045, the first reinforcing plate 045 is overlapped with the first substrate 043 and is fixed to the first substrate 043 and/or the second substrate 044 by riveting, or the first reinforcing plate 045 is integrally formed with the first substrate 043. Further, with respect to the width direction of the first substrate 043, the first reinforcing plate 045 is located at one side of the thirteenth through hole 022, and one side of the first reinforcing plate 045 protrudes out of the first substrate 043. Particularly, when casement 048 is in the state of hanging open, this moment, thirteenth through-hole 022 department on the second connecting seat 002 can receive casement 048's pulling force (like the wind pressure, and the pulling force is mainly located the one side of orientation casement 048 on the second connecting seat), and set up behind first reinforcing plate 045, then can the structural strength of second connecting seat 002, promptly, strengthened the ability of second connecting seat 002 anti-load, and then the stability of hinge 050 in the use improves. Meanwhile, the window is under the state of hanging open, namely, casement 048 is in the tilt state for window frame 047, the pulling force that second connecting seat 002 received at this moment is not the level and is done on window frame 047, namely, this pulling force is for the top of window frame 047, be the biasing pulling force of downward sloping or pull-down, consequently, one side protrusion back outside first base plate 043 of first reinforcing plate 045, can make one side protrusion part card of first reinforcing plate 045 in first base plate 043 hold in the C shape inslot of window frame 047 section bar, and then effectively strengthened second connecting seat 002's anti-load ability, namely, improved the stability of upper hinge 050 in the use.

As shown in fig. 4, in a preferred embodiment, a second reinforcing plate 046 is further included, the second reinforcing plate 046 is overlapped with the first base plate 043 and fixed to the first base plate 043 and/or the second base plate 044 by riveting, or the second reinforcing plate 046 is integrally formed with the first base plate 043. Relative to the width direction of the first substrate 043, the second reinforcing plate 046 is located at one side of the twelfth through hole 021, and one side of the second reinforcing plate 046 protrudes out of the first substrate 043; and/or, the twelfth through holes 021 all penetrate through the first base plate 043, the second base plate 044 and the second reinforcing plate 046. The second reinforcing plate 046 that sets up can strengthen the structural strength of second connecting seat 002, and then improves the second and even seat 002 and link assembly 003 be connected the reliability. Further, one side of the second reinforcing plate 046 protrudes out of the first base plate 043, and the window is in a suspended state, that is, the window sash 048 is in an inclined state relative to the window frame 047, and the second connecting seat 002 is not horizontally acted on the window frame 047 at this time, that is, the pulling force is a downward-inclined biasing force or a downward-pulling biasing force relative to the top of the window frame 047, so that after one side of the second reinforcing plate 046 protrudes out of the first base plate 043, a part of one side of the second reinforcing plate 046 protruding out of the first base plate 043 can be clamped in the C-shaped groove of the profile of the window frame 047, and further, the load resistance of the second connecting seat 002 is effectively enhanced, that is, the stability of the upper hinge 050 during use is improved.

Further, the locking mechanism of the upper hinge 050 is in a locked state, and the outer hinge and the lower hinge 049 together form a longitudinal rotation axis between the sash 048 and the frame 047, so that the sash 048 can rotate relative to the frame 047 to open or close the frame 047. Or, the locking mechanism of the upper hinge 050 is in an unlocked state, and in the height direction relative to the window frame 047, the lower hinge 049 forms a transverse rotating shaft of the window sash 048 and the window frame 047, the first connecting seat 001 of the upper hinge 050 is far away from the second connecting seat 002, and the axes of the first connecting seat 001 and the second connecting seat 002 are relatively parallel, so that the window sash 048 is inclined relative to the window frame 047 by taking the lower hinge 049 as a rotating fulcrum, and the window frame 047 is opened or closed.

As shown in fig. 6-9, in a preferred embodiment, the lower hinge 049 includes a first mount 1, a second mount 2, and an arm assembly movably connected to the first mount 1 and the second mount 2, respectively; wherein the first mounting seat 1 is used for mounting the window sash 048, and the second mounting seat 2 is used for mounting the window frame 047, that is, the window sash 048 and the window frame 047 are movably connected through the lower hinge 049, so as to realize the function of opening or closing the window frame 047 by the window sash 048. Further, the first mounting base 1 can rotate relative to the second mounting base 2 in the horizontal direction relative to the second mounting base 2, and the support arm assembly is used for restraining and enabling the first mounting base 1 to move along a preset track relative to the second mounting base 2; in the use state of the lower hinge 049, the window sash 048 moves in a flat-open manner relative to the window frame 047. Or when the first mounting seat 1 and the second mounting seat 2 are in a folded state and in a longitudinal direction relative to the second mounting seat 2, the first mounting seat 1 and/or the support arm assembly can be inclined relative to the second mounting seat 2, so that a longitudinal axis of the first mounting seat 1 and/or the support arm assembly forms an included angle with a longitudinal axis of the second mounting seat 2; in this situation, the window sash 048 is moved in a suspended manner relative to the window frame 047 in the use position of the lower hinge 049. That is, by making the first mounting seat 1 (for connecting the window sash 048) in the lower hinge 049 horizontally rotatable with respect to the second mounting seat 2 (for connecting the window frame 047), and at the same time making the first mounting seat 1 turnable in the longitudinal direction with respect to the second mounting seat 2, the window sash 048 can be used in a flat-open or hanging-open manner with respect to the window frame 047, so that the window can meet different use requirements; for example, when a better ventilation and light transmission effect is required, the window can be opened in a flat-open mode; and when better security is required, the window can be opened in a suspended manner.

One end of the second supporting arm 4 is rotatably connected with the second mounting base 2 through a hinge bolt 18, the hinge bolt 18 can slide relative to the second mounting base 2, the other end of the second supporting arm 4 is rotatably connected with the first mounting base 1, and the first supporting arm 3 is rotatably connected with the second supporting arm 4 through a pin shaft.

In a preferred embodiment, as shown in fig. 8, in a state where the projection planes of the first and second mounting

seats

1 and 2 coincide in the longitudinal direction, i.e. the lower hinge 049 is in a folded state, the arm assembly may be tilted with respect to the second mounting seat 2 and the longitudinal axis of the first mounting seat 1 forms an angle with the longitudinal axis of the second mounting seat 2, i.e. both the arm assembly and the first mounting seat 1 may be tilted with respect to the second mounting seat 2. Specifically, the lower hinge 049 in the present embodiment is the lower hinge 049, that is, when the hanging function of the utility window is required, the cooperation of the upper and lower hinges 049 is also required; further, in the suspended state, the axis in the width direction of the window sash 048 is a rotation fulcrum at which the window sash 048 is deflected with respect to the window frame 047.

As shown in fig. 9, in the preferred embodiment, the first support arm 3 is provided with a first hinge hole 6, a second hinge hole 7 and a third hinge hole 8 along the length direction thereof, the second support arm 4 is provided with a fourth hinge hole 9, a fifth hinge hole 10 and a sixth hinge hole 11 along the length direction thereof, the first mounting seat 1 is provided with a seventh hinge hole 12 and an eighth hinge hole 13 along the length direction thereof, and the second mounting seat 2 is provided with a ninth hinge hole 14 and a tenth hinge hole 15 along the length direction thereof.

Further, the first hinge hole 6 and the ninth hinge hole 14 are hinged by a hinge pin 18, the second hinge hole 7 and the fifth hinge hole 10 are hinged, the third hinge hole 8 and one end of the connecting rod 5 are hinged and form an eleventh hinge point, the fourth hinge hole 9 and the seventh hinge hole 12 are hinged, the sixth hinge hole 11 and the tenth hinge hole 15 are hinged by a hinge pin 18, wherein the sixth hinge hole 11 can translate along the length direction of the tenth hinge hole 15, that is, the tenth hinge hole 15 is in a strip shape and the tenth hinge hole 15 extends along the length direction of the second mounting seat 2, that is, the hinge pin 18 can slide along the tenth hinge hole 15 or along the length direction of the second mounting seat 2, and the eighth hinge hole 13 and the other end of the connecting rod 5 are hinged and form a twelfth hinge point.

Furthermore, one side of the second supporting arm 4 in the width direction is further provided with a first recess 16, and when the first mounting seat 1 and the second mounting seat 2 are in the folded state, or relative to the window, the window sash 048 is closed in the window frame 047, and the connecting rod 5 is placed in the first recess 16. Further, the third hinge hole 8, the eighth hinge hole 13 and the seventh hinge hole 12 form a triangle, or the two hinge holes on the connecting rod 5 and the seventh hinge hole 12 on the first mounting seat 1 enclose a triangle together, or the eleventh hinge point, the twelfth hinge point and the thirteenth hinge point enclose a triangle together; that is, at this time, since one end of the link 5 is rotatably connected to the first mounting seat 1, the other end of the link 5 is rotatably connected to the first support arm 3, thereby forming an obtuse triangle. Both corner points of this triangle are located on the first mounting seat 1, when (in the closed state of the window, i.e. when the sash 048 and the frame 047 are closed) the triangle needs to be changed, only the third corner point on the connecting rod 5 (when the first support arm 3 is rotated) can be changed, or the third corner point moves in the width direction (left and right) relative to the frame 047, or in the thickness direction (front and back or indoor and outdoor, wherein the eleventh hinge point moves towards the outside and is limited by the first recess 16, further, for the inward opening window, the indoor negative wind pressure is applied to the sash 048, the window hardware bears a component (wind pressure), and the other part of the force is transferred to the frame 047 through the overlapping edge of the sash 048 and the frame 047 hinge point and then transferred to the wall, further, the eleventh hinge point moves towards the indoor as long as the sixth hinge hole 11 moves towards one end of the second mounting seat in the tenth hinge hole 15, but the sixth support arm moves towards the tenth hole 048 when the sixth support arm 10 moves towards the tenth hinge hole 048; at this time, since the link 5 is placed in the first recess 16, this third corner point cannot move in the width direction (left and right) with respect to the window frame 047. Further, the sixth hinge hole 11 of the second support arm 4 is constrained by the tenth hinge hole 15 of the second mounting base 2, and the first recess 16 (located at or facing the indoor side) of the second support arm 4 now accommodates the connecting rod 5, so as to limit the hinge point formed by the connecting rod 5 and the third hinge hole 8 from moving to the outdoor direction. Further, the third hinge hole 8, the fifth hinge hole 10 and the first hinge hole 6 form a triangle; when it is necessary to change the triangle, the first hinge hole 6 is fixed as one corner point, and then the obtuse triangle can be changed into the acute triangle only by rotating the second corner point, i.e., the hinge point (which may be regarded as the fourteenth hinge point) of the second hinge hole 7 and the fifth hinge hole 10, and sliding the third corner point, i.e., the hinge point (which may be regarded as the fifteenth hinge point) of the sixth hinge hole 11 and the tenth hinge hole 15. However, the sixth hinge hole 6 of the second support arm 4 needs to be opened to 10 degrees in the window sash 048 before it can move toward the end of the second mounting seat in the tenth hinge hole 15. Thereby limiting the hinge point formed by the connecting rod 5 and the third hinge hole 8 from moving to the indoor direction. That is, when the lower hinge 049 is in the folded state, the first support arm 3, the second support arm 4 and the connecting rod 5 cooperate with each other and form a self-lock, so that the window sash 048 in the closed state can receive positive or negative wind pressure from the outside, i.e., maintain the relative tightness of the window sash 048 with respect to the window frame 047.

As shown in fig. 7 to 9, in a preferred embodiment, a second recessed portion 17 is further disposed on the second support arm 4 on the other side relative to the first recessed portion 16, when the window sash 048 is opened to 180 degrees relative to the window frame 047 in a side-hung manner, a corner of the window sash 048 may press the second support arm 4, and the disposed second recessed portion 17 may form an avoidance to the side-hung state of the window sash 048, that is, the window sash may be opened to 180 degrees, so that the window has a larger opening degree, and the higher use requirement of people is met. Further, the second support arm 4 forms a complete strip when the lower hinge 049 is in the stowed position, i.e. the indentation (e.g. the second recess 17 for avoiding the corner of the window sash 048; the first recess 16 for receiving the connecting rod 5) provided on the second support arm 4 makes the structure of the lower hinge 049 relatively more compact. Or, the second supporting arm 4 is clamped between the first mounting seat 1 and the first supporting arm 3, and the second supporting arm 4 and the connecting rod 5 are located on the same plane, so that the structure of the lower hinge 049 after being stored is relatively more compact.

In the preferred embodiment, as shown in fig. 9, the ninth hinge hole 14 and the tenth hinge hole 15 are provided with hinge bolts 18, and the hinge bolts 18 are used for enabling the second mounting seat 2 to be hinged with the first support arm 3 and the second support arm 4 respectively; further, the end of the first end of the hinge pin 18 is provided with a chamfered surface 19, and the chamfered surface 19 allows the axis of the hinge pin 18 to be inclined with respect to the axis of the ninth hinge hole 14 or the tenth hinge hole 15. When the first and second mounting

bases

1 and 2 are in the folded state, the chamfered surface 19 is located on one side of the second mounting base 2 in the width direction, and enables the first mounting base 1 or the window sash 048 to be inclined (suspended) relative to the window frame 047. The hinge pin 18 in this embodiment is cylindrical, and the arc of the end of the first end of the hinge pin 18 is a major arc, so that the hinge pin 18 can be tilted with respect to the hinge hole and cannot fall out of the hinge hole. Further, in the thickness direction of the lower hinge 049, one of the hinge pins 18 is loosely fitted to the second mount 2 and the first support arm 3, and the other hinge pin 18 is loosely fitted to the second mount 2 and the second support arm 4, that is, one of the hinge pins 18 may slide with respect to the second mount 2, or both hinge pins 18 may be inclined at a certain angle with respect to one side of the second mount. Further, when the first installation seat 1 is unfolded relative to the second installation seat 2, the support arm assembly is unfolded accordingly, that is, at this time, the first installation seat 1 is horizontally opened (rotated) inwards relative to the second installation seat 2; further, when the first and second mounting

seats

1 and 2 are in the folded state, the first and

second support arms

3 and 4 may drive the corresponding hinge pins 18 to move in the thickness direction of the lower hinge 049 (i.e., the hinge pins 18 may be inclined with respect to the axis of the chain in the thickness direction), so that the first and

second support arms

3 and 4 may roll inward or outward with respect to the second mounting seat 2, and the window sash 048 may be opened in an inward or outward suspension manner with respect to the window frame 047.

Further, by taking a central connection line of the ninth hinge hole 14 and the tenth hinge hole 15 as a reference line, when the first mounting seat 1 and the second mounting seat 2 are in the folded state, centers of the third hinge hole 8 and the eleventh hinge point are located on a first side of the reference line, and centers of the second hinge hole 7 and the fifth hinge hole 10 are located on a second side of the reference line opposite to the first side; further, when the first mounting seat 1 is unfolded to 3-10 degrees to the first side with respect to the second mounting seat 2, the centers of the second hinge hole 7 and the fifth hinge hole 10 cross the reference line to the first side.

As shown in fig. 9, in a preferred embodiment, a first adjusting mechanism is further disposed on the first mounting base 1, and is used for adjusting the position of the first mounting base 1 relative to the second mounting base 2; that is, the first adjustment mechanism is used to finely adjust the front-rear position of the window sash 048 with respect to the window frame 047 to ensure the safety accuracy of the window. Specifically, the first adjusting mechanism comprises a shaft sleeve 20, a jackscrew 21, a first rotating shaft 22 and a second rotating shaft 23, the shaft sleeve 20 is integrally formed with the first mounting seat 1, the shaft sleeve 20 is perpendicular to the first mounting seat 1, the first rotating shaft 22 is integrally formed with the second rotating shaft 23, the axis of the second rotating shaft 23 is deviated from the axis of the first rotating shaft 22, the first rotating shaft 22 is rotatably connected with the shaft sleeve 20, the first rotating shaft 22 can move along the axial direction of the shaft sleeve 20, the second rotating shaft 23 is hinged with the second supporting arm 4, the jackscrew 21 is movably connected with the shaft sleeve 20, and in the longitudinal direction, the jackscrew 21 is used for locking the first rotating shaft 22 in the shaft sleeve 20. For example, after the window is closed, the frame surface of the window sash 048 and the frame surface of the window frame 047 cannot be aligned, at this time, the first rotating shaft 22 may be rotated to further drive the second rotating shaft 23 to rotate, and the first rotating shaft 22 and the second rotating shaft are eccentrically disposed, so that the fine adjustment of the position of the window sash 048 relative to the window frame 047 may be achieved, and the safety quality of the window may be further achieved.
