Preferred embodiments of the present utility model will now be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 8, the present utility model provides a preferred embodiment of a hinge device.

The hinge device includes a base 100, a first lever 210, a second lever 220, a third lever 230, and a fourth lever 240, and further includes a first slider 410 and a second slider 420 slidably disposed on the base 100; wherein the first rod 210 is rotatably disposed on the first slider 410, the third rod 230 is rotatably disposed on the second slider 420, the second rod 220 is rotatably disposed on the base 100, the first rod 210 is rotatably connected with the second rod 220 and the fourth rod 240, respectively, and the fourth rod 240 is rotatably connected with the third rod 230; the second rod 220 is rotatably connected with the base 100 through the eccentric rotating shaft 300, and the second rod 220 is rotatably connected with the base 100 through the eccentric rotating shaft 300, so as to adjust the limit position of the first slider 410 and the second slider 420 which slide in opposite directions.

The hinge device is a door and window hinge structure, is applied to doors and windows, allows the doors or windows to perform rotary motion when being opened and closed, and can enable the doors or windows to be rotatably opened and simultaneously provide support and stability. Preferably, the fourth lever 240 is provided with a window body, and further provided with two chain devices at upper and lower ends of the window body, respectively, to enable the closing and opening of the window body.

The node positions are defined, the connection positions of the first rod 210, the second rod 220 and the third rod 230 and the base 100 are respectively the point a, the point B and the point C, the connection positions of the first rod 210, the second rod 220 and the fourth rod 240 are respectively the point D and the point E, and the connection positions of the third rod 230 and the fourth rod 240 are respectively the point F. And, the limit position is the most limit position reached in the process of sliding the first slider 410 and the second slider 420 in opposite directions, and the first slider 410 and the second slider 420 are adjusted by adjusting the limit position.

In the hinge device closed state, the first, second, third and fourth bars 210, 220, 230 and 240 are all folded into the base 100, i.e., folding and closing of the door and window is achieved. The first slider 410 and the second slider 420 are disposed away from each other, preferably at a far-away limit position, i.e., point a and point C are disposed away from point B, and point D is disposed between point a and point B, and point E is disposed between point B and point F, as to the positional relationship of point C and point F mainly to see the lengths of the third lever 230 and the fourth lever 240. In the opened state of the hinge device, referring to fig. 2, the first, second, third and fourth bars 210, 220, 230 and 240 are disposed at an angle to the length direction of the base 100, and the points D, E and F are gradually distant from the base 100. The first slider 410 and the second slider 420 are slidably disposed adjacent to each other, respectively.

And, the eccentric rotation shaft 300 must be disposed on the second rod 220 to adjust the B point position of the second rod 220, so as to achieve fine adjustment of the rotation track of the fourth rod 240, if disposed at other rotation positions, such as the a point and the C point, not only the rotation track of the fourth rod 240 cannot be fine adjusted, but also the maximum stroke or the minimum stroke position of the a point or the C point is disturbed, which results in that the hinge device cannot be completely combined to be closed or completely opened.

In this embodiment, a fixed block 500 is fixedly disposed on the base 100, the fixed block 500 is disposed between the first slider 410 and the second slider 420, and the second lever 220 is rotatably coupled to the fixed block 500 through the eccentric rotation shaft 300. The second lever 220 is directly disposed on the base 100 through the eccentric rotation shaft 300, or indirectly disposed on the base 100 through the eccentric rotation shaft 300 disposed on the fixed block 500.

Wherein, the fixing block 500 is provided with a hole site 520, and is matched with an external fixing structure to fix the value of the base 100.

The provision of the fixing block 500 brings the following advantages: first, the installation is facilitated, and the installation and adjustment are more convenient, i.e., the second lever 220 is installed to the fixing block 500, and the fixing block 500 is installed to the base 100 again; second, the rotation bearing force is transferred, and the fixing block 500 can transfer the rotation bearing force of the second lever 220 to the fixing block 500, thereby better protecting the base 100 and reducing the abrasion to the base 100; third, the fixing block 500 can bear the abrasion caused by the second rod 220, and the service life of the hinge device is prolonged; fourth, by selecting the fixing blocks 500 of the corresponding thickness, the relative height of the second lever 220 can be appropriately adjusted, thereby enabling the hinge device to have higher flexibility to match the assembly requirements of other levers, such as the first lever 210, the third lever 230, and the fourth lever 240.

In the present embodiment, referring to fig. 3 to 5, the eccentric rotation shaft 300 includes a first rotation shaft 310 provided on the second lever 220 and a second rotation shaft 320 provided on the fixed block 500, the first rotation shaft 310 and the second rotation shaft 320 being eccentrically disposed. Specifically, the eccentric rotation shaft 300 is rotatable relative to the fixed block 500 through the second rotation shaft 320, so as to rotate the second rotation shaft 320 around the first rotation shaft 310, thereby adjusting the rotation center position of the second rod 220, i.e., adjusting the relative position of the point B on the base 100. By rotating the eccentric rotation shaft 300, the rotation center position of the second lever 220 can be changed to perform a fine adjustment movement on the base 100 up and down left and right, and the fine adjustment movement can fine adjust the final opened or closed position of the door and window so as to be better adapted to the door and window frame.

Wherein the second lever 220 is provided with a through hole 221 fitted in match with the first rotation shaft 310, and the fixing block 500 is provided with a through hole 510 fitted with the second rotation shaft 320, although the second rotation shaft 320 is provided in a corresponding through hole of the base 100 if the fixing block 500 is not provided.

The eccentric rotary shaft 300 further includes a first limiting member 311 and a second limiting member 321 disposed on the first rotary shaft 310 and the second rotary shaft 320, respectively. The end surfaces of the second rod 220 and the fixed block 500 that are abutted against each other are inner side surfaces, and the end surfaces that are opposite to each other are outer side surfaces, so as to provide a preferable scheme of the first limiting member 311 and the second limiting member 321: the first limiting member 311 is disposed on an end surface of the first shaft 310 and on an outer side surface of the second rod 220, and the second limiting member 321 is disposed on an end surface of the second shaft 320 and on an outer side surface of the fixed block 500.

Wherein the first stopper 311 contacts with the outer side surface of the second rod 220 to restrict the movement of the second rod 220 in the longitudinal direction, preventing it from being separated from the fixed block 500, and at the same time, the contact does not affect the rotation of the second rod 220 on the fixed block 500, maintaining the normal movement of the hinge device. By improving the degree of close fitting of the first and second stoppers 311 and 321 with the second lever 220 and the fixing block 500, stability of the second lever 220 during rotation can be ensured. The longitudinal deflection of the second rod 220 is reduced, and at the same time, a certain sliding friction is limited, and when a larger force is applied, the second rod 220 can still be smoothly rotated, but under a slight force, the second rod 220 cannot accidentally move, so that the door and window can be effectively prevented from shaking due to wind force and the like. Of course, the first rod 210 and the third rod 230 can also provide corresponding friction forces on the first slider 410 and the second slider 420, thereby cooperatively improving overall stability.

Further, referring to fig. 5, another preferred embodiment of the first stopper 311 is provided. The outer side surface of the second rod 220 is provided with a limiting groove 222, and the first limiting piece 311 is clamped in the limiting groove 222. The purpose is to hide the first limiting piece 311 into the limiting groove 222, and in the process of accommodating the first rod 210 and the second rod 220, since the first rod 210 is above the second rod 220, the first limiting piece 311 of the second rod 220 is prevented from colliding with the first rod 210, and smooth movement of the door and window in the accommodating process is ensured.

In one embodiment, referring to fig. 5, an adjusting structure 330 is disposed on the end surface of the eccentric rotary shaft 300 near the second rod 220, for adjusting the relative rotation position of the eccentric rotary shaft 300 and the fixed block 500, that is, adjusting the rotation position of the eccentric rotary shaft 300 relative to the fixed block 500; the eccentric rotary shaft 300 further includes a marking structure disposed adjacent to the adjustment structure 330. Preferably, the adjusting structure 330 is an adjusting groove disposed on the end surface of the eccentric rotating shaft 300, and may be a protruding structure.

Wherein, the end surface of the eccentric rotary shaft 300 near the second rod 220 is further provided with a marking structure 340 to identify the rotation direction of the eccentric rotary shaft 300 or indicate the direction of the point B.

Specifically, the tool is inserted into the adjusting groove, such as a cross groove, a straight groove, a polygonal groove, etc., and the tool is also inserted into the protrusion structure, such as the protrusion structure having a non-circular cross-sectional shape, to rotate the eccentric rotary shaft 300, thereby adjusting the position of the center of rotation of the second lever 220.

In the present embodiment, referring to fig. 6 to 9, the second lever 220 is rotated with respect to the base 100 by the eccentric rotation shaft 300, and the position of the rotation center of the second lever 220 is adjusted by adjusting the rotation direction of the eccentric rotation shaft 300 with respect to the base 100, i.e., adjusting the relative position of the point B on the base 100. Wherein the rotation of the eccentric rotation shaft 300 is provided on the base 100, and the eccentric shaft is rotatably provided on the second lever 220, the eccentric rotation shaft 300 can be rotated with respect to the base 100, thereby adjusting the relative position of the B point on the base 100.
