[0045] Embodiment:

[0046] As Figures 1-7 shown, in this embodiment, an upper hinge mechanism for an externally - suspended and externally - horizontal opening window is provided, including an upper frame mounting plate 1, an upper sash fixing plate 2, a first support arm 3 and a second support arm 4;

[0047] One ends of the first support arm 3 and the second support arm 4 are respectively slidably hinged and in clearance fit with the upper sash fixing plate 2;

[0048] The other end of the first support arm 3 is axially rotatably hinged and mated with the upper frame mounting plate 1, and the other end of the second support arm 3 is axially rotatably hinged and in clearance fit with the other end of the upper sash fixing plate;

[0049] A first eccentric member 5 is provided on the second support arm 4, and the eccentric end of the first eccentric member 5 is pivotally connected to the first support arm 3.

[0050] The upper frame mounting plate 1 of this embodiment is installed at the window frame profile, and the upper sash fixing plate 2 is fixed to the window sash. Through the hinged connection structure of the first support arm 3 and the second support arm 4, the state adjustment of the upper sash fixing plate 2 relative to the upper frame mounting plate 1 for externally - suspended opening, externally - horizontal opening and locking can be realized;

[0051] And because the upper fan fixing plate 2 is hinged and has a clearance fit with the first support arm 3 and the second support arm 4, the clearance structure at the above-mentioned connection can enable the upper fan fixing plate 2 to adjust the axis flipping angle relative to the length direction of the upper frame mounting plate 1;

[0052] At the same time, because the second support arm 4 and the first support arm 3 are eccentrically pivoted, specifically, the first eccentric member is provided at the middle hinge of the first support arm and the second support arm, and the eccentric end of the first eccentric member is pivotally connected to the first support arm. See Figure 6 and Figure 7 , the adjustment of the front and rear displacement of the upper fan fixing plate 2 relative to the upper frame mounting plate 1 can be realized by adjusting the first eccentric member 5, so that the rubber strip at the window sash fixed to the upper fan fixing plate 2 fits more tightly against the window frame profile, and the sealing effect can be adjusted.

[0053] In this embodiment, see Figures 3 to 5 , the specific connection structure of the upper fan fixing plate 2 with the first support arm 3 and the second support arm 4 is as follows:

[0054] The upper fan fixing plate 2 is provided with a first rectangular hole 201. A first connecting member 6 is arranged in the first rectangular hole 201. A first gasket 7 that is slidably matched with the upper fan fixing plate 2 is arranged on the first connecting member 6. One end of the first connecting member 6 has a clearance fit with the first support arm 3. One end of the first support arm is slidably hinged and has a clearance fit with the first rectangular hole of the upper fan fixing plate through the first connecting member.

[0055] Specifically, the width dimension of the first rectangular hole 201 is greater than the diameter dimension of the first connecting member 6.

[0056] Specifically, the upper fan fixing plate 2 is provided with a second connecting member 8. One end of the second connecting member 8 has a clearance fit with the second support arm 4. One end of the second support arm is axially rotatably hinged and has a clearance fit with the other end of the upper fan fixing plate through the second connecting member.

[0057] Through the structure of the smaller clearance formed by the clearance fit of the above-mentioned connecting members at the hinge, when the hinge is cantilevered, that is, when the first support arm 3 and the second support arm 4 are in an open state relative to the upper frame mounting plate 1 and the window sash is in an open state, the fan support arm can tilt slightly forward and backward relative to the first support arm 3, the second support arm 4 and the upper frame mounting plate 1. And the structural design that the width dimension of the first rectangular hole 201 is greater than the diameter dimension of the first connecting member 6 further facilitates the small-angle forward and backward tilting of the fan support arm.

[0058] On the upper frame mounting plate 1 of this embodiment, a second eccentric member 9 is provided. The eccentric end of the second eccentric member 9 is pivotally connected to an adjusting plate 10. On the upper frame mounting plate 1, a fourth rectangular hole 102 is provided. At the other end of the adjusting plate 10, a fourth connecting member 15 is provided. The other end of the adjusting plate passes through the fourth rectangular hole of the upper frame mounting plate through the fourth connecting member and is hinged to the first support arm.

[0059] For the above structure, specifically, on the upper frame mounting plate 1, a second rectangular hole 101 is provided. On the adjusting plate 10, a third rectangular hole 1001 is provided. At the other end of the second support arm 4, a third connecting member 11 that cooperates with the second rectangular hole 101 and the third rectangular hole 1001 is provided. On the third connecting member 11, a second gasket 12 is provided. The second gasket 12 is in sliding fit with the adjusting plate 10.

[0060] Specifically, at the third connecting member 11, an upper hinge slider 13 is provided. The upper hinge slider 13 is in sliding fit with the second rectangular hole 101 and the third rectangular hole 1001.

[0061] By adjusting the second eccentric member 9, the adjustment of the front-back displacement of the adjusting plate 10 relative to the upper frame mounting plate 1 is realized, and the front-back displacement adjustment of the first support arm 3 is driven, so as to realize the fine adjustment of the overall structure.

[0062] Both the above first eccentric member 5 and second eccentric member 9 are provided on the upper hinge mechanism of the outward-suspended and outward-hinged window. The operator can complete the adjustment without putting his head out of the window indoors, and the operation is safer.

[0063] The specific structure of the upper frame mounting plate 1 of this embodiment is as follows:

[0064] The upper frame mounting plate 1 is of an L-shaped structure, including a transverse upper frame mounting plate body 1 and a longitudinal upper frame mounting plate body 1. The adjusting plate 10 is arranged at the transverse upper frame mounting plate body 1.

[0065] Specifically, clamping pieces 14 are riveted at the transverse upper frame mounting plate body 1, the longitudinal upper frame mounting plate body 1 and the adjusting plate 10.

[0066] The above structure can make the hanging fan installation more convenient: when the upper hinge mechanism of the outward-suspended and outward-hinged window is assembled with the window sash, when the window sash and the window frame profile are assembled, the assembly can be completed only by locking the clamping piece and the window frame profile.

[0067] At the same time, a positioning convex portion 202 can also be provided at one end of the upper sash fixing plate 2, which is used for quick positioning when the window sash is installed on the upper sash fixing plate 2, facilitating the installation.

[0068] To sum up, the advantages of this application are as follows:

[0069] 1. It can realize the functional requirements of the above three states: outward suspension opening, outward hinge opening, and locking;

[0070] 2. The structural design of the eccentric part realizes the function of left - right adjustment at the upper hinge mechanism, avoiding setting it at the fan support arm. This allows a person standing indoors to complete the adjustment without putting their head out of the window, which is safer.

[0071] 3. The structural design of the eccentric part realizes the adjustment of the front - rear displacement of the upper fan fixing plate 2 relative to the upper frame mounting plate 1, making the rubber strip at the window sash fixed to the upper fan fixing plate fit more tightly against the window frame profile, and enabling adjustment of the sealing effect.

[0072] 4. The overall installation is more convenient: When the upper hinge mechanism of the outward - opening and outward - horizontal window is assembled with the window sash, during the assembly of the window sash and the window frame profile, the assembly can be completed simply by locking the clamping piece with the window frame profile.

[0073] 5. When in the outward - opening window state, the upper fan fixing plate has a clearance fit with the first connecting piece and the second connecting piece, and enables the upper fan fixing plate to have an axis - flipping angle change in the length direction relative to the upper frame mounting plate, so as to adjust the small - angle front - rear tilt angle of the upper fan fixing plate 2 relative to the upper frame mounting plate 1 to adapt to different usage scenarios.

[0074] The above - mentioned 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 - mentioned 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.
