Referring to fig. 1 and 2, an embodiment of the present application provides a hinge assembly 100 for connecting a door window and a door sash to open and close the door window. Wherein, the door leaf is an inward opening downward hanging door or an inward opening downward hanging window. In particular, the hinge assembly 100 may be used to connect a door leaf with a door frame, and may also be used to connect a window sash with a window frame. Referring to fig. 4, in the embodiment of the present invention, a hinge assembly 100 is illustrated as an example for connecting a window sash 10 with a window frame (not shown).

Referring to fig. 1 and 2 and 6, the hinge assembly 100 includes a frame mounting base 110, a driving lever 120, a stay assembly 130, a pull rod 140, and an anti-sloshing adjusting assembly 150.

Specifically, the frame mount 110 is for mounting on a window frame. Referring to fig. 4, the driving lever 120 is for mounting on the window sash 10. The supporting piece assembly 130 includes a first supporting piece 131, a second supporting piece 132 and a third supporting piece 133. The leg assembly 130 is connected to the frame mount 110 and the pull rod 140, respectively. When the hinge assembly 100 is connected to the window sash 10 and the window frame, respectively, and the window sash 10 is in a side-hung state, the extending direction of the pull rod 140 is substantially identical to the extending direction of the transmission rod 120, and the pull rod 140 and the transmission rod 120 are stacked. The tie rod 140 is positioned above the drive rod 120. When the window sash 10 is in the side-hung state, the pull rod 140 moves relative to the frame installation base 110 through the stay assembly 130. The specific structure and operation principle of the frame mounting seat 110, the driving rod 120, the support member assembly 130 and the pull rod 140 are prior art and will not be described herein.

Referring to fig. 5, a sliding groove 11a is formed on the profile 11 of the window sash 10. When the window sash 10 is in the horizontally-opened state, the pull rod 140 is stacked above the transmission rod 120, and a gap s exists between an end surface of the pull rod 140 in the width direction and a side wall of the sliding groove 11 a. Therefore, when the window sash 10 is in the side-hung state, the existence of the gap s allows a space for relative movement between the profile 11 of the window sash 10 and the pull rod 140, which may cause a problem that the window sash 10 shakes when the window sash 10 is in the side-hung state. The embodiment of the present application improves the shaking of the window sash 10 by providing the anti-shaking adjustment assembly 150 on the pull rod 140.

Referring to fig. 7 and 8, the anti-sloshing adjusting assembly 150 includes: a fixing portion 151, an adjusting portion 152, and a screw connector 153.

The fixing portion 151 is fixedly connected to the pull rod 140. Specifically, the fixing portion 151 may be a fixing block or a fixing piece. The fixing portion 151 may be attached to the upper surface of the tie bar 140, and the fixing portion 151 and the tie bar 140 may be fixedly connected by a connector such as a bolt. The fixing portion 151 may be fixedly connected to the pull rod 140 by welding, bonding, or the like. The adjustment portion 152 may be an adjustment block or an adjustment tab.

As shown in fig. 8, in the present embodiment, the regulating portion 152 is provided with the mounting groove 104. The mounting groove 104 has openings (not numbered) at both ends thereof, and the openings are oriented in the same direction as the width direction of the pull rod 140. The fixing portion 151 may be inserted into the mounting groove 104 along the width direction of the drawbar 140. The fixing portion 151 is fitted to the mounting groove 104, thereby facilitating the assembly of the adjusting portion 152 and the fixing portion 151.

The fixing portion 151 is provided with a first connection hole 101. The adjusting portion 152 is provided with a second connecting hole 102. In the present embodiment, the first connection hole 101 is a threaded hole. The second connection holes 102 are bar-shaped holes (commonly called kidney-shaped holes). As shown in fig. 8, the length direction of the strip-shaped hole is along the width direction of the tie bar 140. The threaded connection member 153 is sequentially inserted into the bar-shaped hole and the threaded hole from the top down, and the threaded connection member 153 is screwed with the threaded hole, so that the fixing portion 151 and the adjusting portion 152 can be fastened and connected by the threaded connection member 153.

In the present embodiment, the threaded connector 153 is a bolt. The bolt head of the bolt is positioned above the adjusting part 152 and abuts against the adjusting part 152, so that the adjusting part 152 can be partially sandwiched between the bolt head and the fixing part 151, and the adjusting part 152 can be prevented from moving relative to the fixing part 151 in the thickness direction, so that the position of the adjusting part 152 can be reliably stabilized.

As shown in fig. 7, the adjustment portion 152 protrudes beyond an end surface of one end of the tie bar 140 in the width direction of the tie bar 140. Specifically, as shown in fig. 8, one end of the fixing portion 151 is fixedly connected to the pull rod 140, and the other end thereof exceeds one end of the pull rod 140 in the width direction of the pull rod 140. The adjusting portion 152 is sleeved on the other end of the fixing portion 151 through the mounting groove 104. Therefore, the adjustment portion 152 exceeds one end of the tie bar 140 in the width direction of the tie bar 140. Since the adjustment portion 152 exceeds one end of the tie bar 140 in the width direction of the tie bar 140, the adjustment portion 152 is located at least partially on one side in the width direction of the tie bar 140. It is understood that the adjusting portion 152 may be partially located on one side in the width direction of the pull rod 140, or may be entirely located on one side in the width direction of the pull rod 140.

Referring to fig. 5, since the adjusting portion 152 is at least partially located at one side of the pull rod 140 in the width direction, the adjusting portion 152 is at least partially located between the side wall of the sliding slot 11a and the end surface of the pull rod 140 in the width direction, i.e., located in the gap s. It can be seen that the adjusting portion 152 can at least partially occupy the gap s, that is, the adjusting portion 152 can occupy the space where the pull rod 140 and the profile 11 of the window sash 10 move relatively, so that the relative movement between the profile 11 of the window sash 10 and the pull rod 140 can be reduced or avoided, and the shaking of the window sash 10 in the flat-open state can be reduced or avoided.

The adjusting portion 152 is adjustable in position relative to the fixing portion 151 in a first direction, which is a width direction of the draw bar 140.

Specifically, the position of the adjustment portion 152 may be moved in the width direction of the draw bar 140 by loosening the threaded connection 153. Since the second connection hole 102 of the adjustment portion 152 is a strip-shaped hole, and the length direction of the strip-shaped hole is along the width direction of the pull rod 140, even if the position of the adjustment portion 152 is moved along the width direction of the pull rod 140, the second connection hole 102 and the first connection hole 101 can still correspond to each other, so that the adjustment portion 152 and the fixing portion 151 can still be fixedly connected through the threaded connection 153.

By moving the position of the adjusting portion 152 in the width direction of the pull rod 140, the distance between the adjusting portion 152 and the side wall of the sliding groove 11a can be adjusted, so that the degree of the gap s occupied by the adjusting portion 152 can be adjusted, that is, the relative moving range of the pull rod 140 and the profile 11 of the window sash 10 is adjusted, and the shaking problem of the window sash 10 in the flat-open state can be better improved.

It can be understood that when the adjusting portion 152 is tightly attached to the side wall of the sliding slot 11a, there is no gap between the adjusting portion 152 and the sliding slot 11a, and the window sash 10 can be completely prevented from shaking in the flat-open state theoretically.

When the hinge assembly 100 is used to connect the window sash 10 and the window sash 10 is in a horizontally opened state, the adjusting portion 152 is at least partially located on one side of the pull rod 140 in the width direction, and therefore, the adjusting portion 152 is at least partially located between the side wall of the sliding groove 11a and the end surface of the pull rod 140 in the width direction. Therefore, the adjusting portion 152 can occupy the gap s between the side wall of the sliding groove 11a and the end surface of the pull rod 140 in the width direction, that is, the adjusting portion 152 occupies the space where the pull rod 140 and the profile 11 of the window sash 10 move relatively, so that the relative movement between the profile 11 of the window sash 10 and the pull rod 140 can be reduced or avoided, and further the shaking of the window sash 10 in the flat-open state can be reduced or avoided. By moving the position of the adjusting portion 152 in the width direction of the pull rod 140, the distance between the adjusting portion 152 and the side wall of the sliding groove 11a can be adjusted, so that the degree of the gap s occupied by the adjusting portion 152 can be adjusted, and the shaking problem of the window sash 10 in the side-hung state can be improved.

It is understood that in other embodiments, the second connection holes 102 may be threaded holes, and the first connection holes 101 may be strip-shaped holes, so that when the position of the adjustment portion 152 is moved along the width direction of the pull rod 140, the second connection holes 102 and the first connection holes 101 can correspond to each other, so that the adjustment portion 152 and the fixing portion 151 can still be fixedly connected through the threaded connection members 153.

In an embodiment, the engagement of the fixing portion 151 and the mounting groove 104 can define a relative position of the adjusting portion 152 and the fixing portion 151 along a second direction and a relative position along a third direction, wherein the second direction is a length direction of the pull rod 140, and the third direction is a thickness direction of the pull rod 140.

Specifically, as shown in fig. 8, the mounting groove 104 has a first sidewall 1042 and a second sidewall (not numbered). The first side wall 1042 and the second side wall are disposed at an interval along the length direction of the pull rod 140 and are disposed opposite to each other. The side surfaces of the fixing portion 151 are respectively attached to the first side wall 1042 and the second side wall, so that the relative positions of the adjusting portion 152 and the fixing portion 151 along the length direction of the pull rod 140 can be defined.

As shown in fig. 8, the mounting slot 104 has a third side wall 1041 and a fourth side wall (not numbered). The third side wall 1041 and the fourth side wall are disposed at an interval along the thickness direction of the tie bar 140 and are disposed opposite to each other. The upper and lower surfaces of the fixing portion 151 are respectively attached to the third and

fourth sidewalls

1041 and 151, so that the relative positions of the adjusting portion 152 and the fixing portion 151 in the thickness direction of the draw bar 140 can be defined.

Because the fixing portion 151 is fixedly connected with the pull rod 140, the relative position between the adjusting portion 152 and the fixing portion 151 along the second direction and the relative position along the third direction are limited, so that the relative position between the adjusting portion 152 and the pull rod 140 is stable, the position of the adjusting portion 152 along the width direction of the pull rod 140 is stable and reliable, and the shaking problem of the window sash 10 in the flat-open state can be effectively improved.

Referring to fig. 8, in an embodiment, the fixing portion 151 is provided with a plurality of positioning slots 105, and the positioning slots 105 are sequentially arranged at intervals along the width direction of the pull rod 140. The adjustment portion 152 is provided with a stopper portion (not shown) that can be selectively engaged with any one of the positioning grooves 105.

Specifically, as shown in fig. 8, in the present embodiment, the number of the positioning grooves 105 is 10, and the positioning grooves are arranged in two rows along the length direction of the pull rod 140. The number of positioning grooves 105 in each row is five. The five positioning grooves 105 in each row are sequentially arranged at intervals in the width direction of the pull rod 140.

The limiting part can be a limiting sheet, a limiting rib plate, a limiting rib and the like. The limiting part is positioned on the inner wall of the mounting groove 104. In this embodiment, the number of the position limiting portions may be two, and each position limiting portion corresponds to one row of the positioning grooves 105. Each stop portion may cooperate with one of the detents 105 in the corresponding column.

Through the cooperation of the limiting part and the positioning groove 105, the relative positions of the fixing part 151 and the adjusting part 152 in the width direction of the pull rod 140 can be further limited, so that the adjusting part 152 can more reliably occupy the gap s, the distance between the adjusting part 152 and the side wall of the sliding groove 11a can be more reliably limited, and the shaking problem of the window sash 10 in the flat-open state can be effectively solved.

Through adjusting the position of the limiting part, the limiting part is matched with different positioning grooves 105 in the width direction of the pull rod 140, the position of the adjusting part 152 in the width direction of the pull rod 140 can be adjusted, the distance between the adjusting part 152 and the side wall of the sliding groove 11a can be adjusted, the degree of the gap s occupied by the adjusting part 152 can be adjusted, and the shaking problem of the window sash 10 in the flat-open state can be better solved.

It is understood that in other embodiments, the positioning slots 105 may be arranged in only one row. The number of detents 105 may also be other numbers.

In another embodiment, the number of the limiting parts can be more. For example, two or more stopper portions are sequentially arranged at intervals in the width direction of the pull rod 140. In this embodiment, the number of the limiting portions may be four, and the limiting portions are arranged in two rows, and two limiting portions are arranged at intervals in each row along the width direction of the pull rod 140. Each of which cooperates with a positioning slot 105. Through the cooperation of more limiting parts and the positioning grooves 105, the relative positions of the fixing part 151 and the adjusting part 152 in the width direction of the pull rod 140 can be more reliably limited, so that the adjusting part 152 can more reliably occupy the gap s, the distance between the adjusting part 152 and the side wall of the sliding groove 11a can be more reliably limited, and the shaking problem of the window sash 10 in the flat-open state can be effectively solved.

It is understood that in other embodiments, the positioning groove 105 may be disposed on the adjusting portion 152. The stopper may be disposed on the fixing portion 151. The position of the regulating portion 152 in the width direction of the pull rod 140 can also be adjusted by engaging the stopper portion with different positioning grooves 105 in the width direction of the pull rod 140.

Referring to fig. 2 and 3, in one embodiment, the hinge assembly 100 further includes a locking block 160 and an eccentric rivet 170. The lock block 160 is disposed on the drive link 120. The lock block 160 is provided with a limit groove 106. The eccentric rivet 170 is fixedly connected to the pull rod 140. The eccentric rivet 170 is used to mate with the retaining groove 106.

Specifically, as shown in fig. 3, when the window sash 10 is in the flat-open state, the eccentric rivet 170 is located in the limiting groove 106. Because the eccentric rivet 170 is fixedly connected with the pull rod 140, and the locking block 160 is disposed on the transmission rod 120, the pull rod 140 and the transmission rod 120 can be relatively positioned by the cooperation of the eccentric rivet 170 and the limiting groove 106, so that the pull rod 140 and the transmission rod 120 can be stacked and the extending directions of the two are substantially the same when the window sash 10 is in a flat-open state. The specific structure, the matching process and the principle of the locking block 160 and the eccentric rivet 170 are prior art and will not be described herein.

In this embodiment, the eccentric rivet 170 may also be rotated, so that the eccentric rivet 170 may drive the locking block 160 to slightly rotate, the locking block 160 drives the transmission rod 120, and the transmission rod 120 drives the profile 11 of the window sash 10 to slightly rotate, thereby achieving fine adjustment of a gap s between a side wall of the profile 11 of the window sash 10 and an end surface of the pull rod 140 in the width direction, so as to improve the wobbling problem of the window sash 10 when being opened or closed in a flat-open state. The way of adjusting the gap s between the side wall of the profile 11 of the window sash 10 and the end surface of the pull rod 140 in the width direction by the eccentric rivet 170 is the prior art, and the detailed process and principle thereof are not described herein again.

Another embodiment of the present application also provides a door and window assembly (not shown). The window and door assembly includes a window and door sash, a window and door frame, and a hinge assembly 100 as in any one of the above. The frame mount 110 is for mounting on a window and door frame, and the driving lever 120 is for mounting on a window and door sash.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
