The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0041] Embodiment:

[0042] As Figures 1-5 shown, in this embodiment, a lower hinge mechanism for an externally suspended and externally horizontal window is provided, including a frame mounting plate 1, a first support arm 2, a second support arm 3, an adjustment link 4, a diagonal tension bar 5 and a diagonal tension bar seat 6;

[0043] A first rectangular hole 502 is provided on the diagonal tension bar 5. One end of the first support arm is provided with a first rivet member 201 and is slidably hinged to the first rectangular hole in the diagonal tension bar through the first rivet member;

[0044] The other end of the first support arm is provided with a first connecting member 102 and is rotatably hinged to the frame mounting plate through the first connecting member. One end of the adjustment link 4 is fixedly hinged to the first connecting member 102 at the same time;

[0045] One end of the second support arm is provided with a second rivet member 301 and is rotatably hinged to the other end of the diagonal tension bar through the second rivet member;

[0046] A second rectangular hole 104 is provided on the frame mounting plate. The other end of the second support arm is provided with a second connecting member 103 and is slidably hinged to the second square hole of the frame mounting plate through the second connecting member;

[0047] The first support arm and the second support arm are hinged in the middle;

[0048] A first eccentric member 101 is provided on the frame mounting plate 1. The eccentric end of the first eccentric member 101 is pivotally connected to the other end of the adjustment link 4;

[0049] One end of the diagonal tension bar 5 is hinged to the diagonal tension bar seat 6.

[0050] The frame mounting plate 1 of the present application is installed at the window frame profile 11, and the diagonal tie rod seat 6 is fixed to the window sash profile 12. Through the articulated connection structure of the first support arm 2, the second support arm 3 and the diagonal tie bar 5, the state adjustment of the diagonal tie rod seat 6 relative to the frame mounting plate 1 can be realized for outward suspension opening, outward side-hung opening and locking;

[0051] And because the first eccentric member 101 is provided on the frame mounting plate 1, the position of the adjusting link 4 can be adjusted through the first eccentric member 101, avoiding the problem of inconvenient adjustment when arranged at the position of the window sash profile 12, and the user can complete the adjustment of the position of the window sash profile 12 indoors.

[0052] At the same time, in this embodiment, the sealing degree of the doors and windows can also be adjusted when the doors and windows are closed:

[0053] Specifically, a second eccentric member 501 is provided on the diagonal tie bar 5, a lower articulated transmission link 601 is provided on the diagonal tie rod seat 6, and a lower articulated joint 602 is provided on the lower articulated transmission link 601. As Figure 5 , when the lower articulated transmission link 601 overlaps with the diagonal tie bar 5 in position, the eccentric end of the second eccentric member 501 cooperates with the lower articulated joint 602.

[0054] Specifically, the number of the second eccentric members 501 is two and they are arranged along the length extension direction of the diagonal tie rod seat 6.

[0055] In the above structure, when the lower articulated transmission link 601 overlaps with the diagonal tie bar 5 in position, that is, when the doors and windows are in the closed state, at this time, by rotating the position of the second eccentric member 501, the position of the lower articulated joint 602 can be changed, so that the window sash profile 12 approaches or moves away from the window frame profile 11, playing a role in adjusting the sealing degree of the doors and windows.

[0056] In this embodiment, the specific connection structure of the first support arm 2, the second support arm 3 and the diagonal tie bar 5 is as follows:

[0057] Specifically, a lower articulated slider 401 that cooperates with the second connecting member 103 at the frame mounting plate 1 is provided on the adjusting link 4, and the other end of the second support arm 3 is pivotally connected to the lower articulated slider 401.

[0058] At the same time, this embodiment also has the effect of being able to resist external wind pressure:

[0059] As Figure 4 , at one end of the diagonal tie bar 5, a wind pressure resistance seat 7 that is slidably matched with the diagonal tie rod seat 6 is provided. An anti-wind pressure movable rod 8 is provided on the diagonal tie rod seat 6, and an anti-wind pressure limiting portion that can cooperate with the anti-wind pressure movable rod 8 is provided on the wind pressure resistance seat 7. Specifically, the anti-wind pressure limiting portion includes a fixed sliding groove portion 701 and an unlocking sliding groove portion 702, and a sliding member 801 that cooperates with the fixed sliding groove portion 701 or the unlocking sliding groove portion 702 is provided at one end of the anti-wind pressure movable rod 8.

[0060] Adjust the sliding position of the wind pressure resistance seat 7 on the diagonal tension rod seat 6. When the fixed sliding groove portion 701 of the wind pressure resistance seat 7 cooperates with the sliding member 801 of the wind pressure resistance movable rod 8, it has a limiting effect, thereby restricting the movement of the diagonal tension bar 5 and ensuring the hovering state, so as to resist the external wind pressure. When the position of the sliding member 801 of the wind pressure resistance movable rod 8 is adjusted to cooperate with the unlocking sliding groove portion 702, the effect of restricting the movement of the diagonal tension bar 5 is released to close the doors and windows.

[0061] The frame mounting plate 1 of this embodiment is of an L-shaped structure, including a horizontal frame mounting plate 1 and a vertical frame mounting plate 1. The vertical frame mounting plate 1 is provided with one directional clamping piece 9, and the horizontal frame mounting plate 1 is provided with two directional clamping pieces 9. The fixed connection with the window frame profile 11 can be conveniently realized through the directional clamping pieces 9.

[0062] Specifically, screw members 10 for connecting the window sash profile 12 are provided at the middle and both sides of the diagonal tension rod seat 6, and the fixation with the window sash profile 12 is realized through the three screw members 10, and the fixing structure is reliable.

[0063] In summary, the advantages of this application are as follows:

[0064] 1. It can realize the functional requirements of the above three states: external suspension opening, external side-hung opening, and locking.

[0065] 2. The first eccentric member 101 is arranged on the frame mounting plate 1. Through the first eccentric member 101, the position of the adjusting link 4 can be adjusted, avoiding the problem of inconvenient adjustment when arranged at the position of the window sash profile 12, and the user can complete the adjustment of the position of the window sash profile 12 indoors.

[0066] 3. The second eccentric member 501 is arranged on the diagonal tension bar 5, and the sealing degree of the doors and windows can be adjusted when the doors and windows are closed, avoiding the problem of inconvenient adjustment when arranged at the position of the window sash profile 12, and the user can complete the adjustment of the sealing degree indoors.

[0067] 4. The overall installation is more convenient: only through the directional clamping pieces 9 and the window frame profile 11, the assembly can be completed; the fixing structure is firm, and the three screw members 10 provided realize the fixation with the window sash profile 12, and the fixing structure is reliable.

[0068] 5. The overall structure is reasonably designed, and while ensuring the mentioned thickness, it can have the effects of wind pressure resistance and load-bearing.

[0069] The above is only a preferred embodiment of the present invention, and it does 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.
