[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] See also Figure 1-Figure 8 , respectively, are schematic diagrams of the structure of the sealing adjustable hinge of the utility model and the structure of its components.

[0025] As shown in the figure, an embodiment of the utility model provides a sealing adjustable hinge, whose overall structure includes a frame mounting seat 1, a first connecting rod 2, a second connecting rod 3, a third connecting rod 4, a sash mounting rod 5 and a sealing adjustment mechanism 6, one end of the first connecting rod 2 is hinged to one end of the frame mounting seat 1, the other end of the first connecting rod 1 is hinged to one end of the third connecting rod 4, the middle part of the first connecting rod 1 is hinged to the middle part of the second connecting rod 3, one end of the second connecting rod 3 is hinged to the other end of the frame mounting seat 1, the other end of the second connecting rod 3 is hinged to one end of the sash mounting rod 5, and the other end of the third connecting rod 4 is hinged to the middle part of the sash mounting rod 5, one end of the frame mounting seat 1 is extended upward to provide a vertical plate 11, the sealing adjustment mechanism 6 is arranged on the inner side of the vertical plate 11, and the sealing of the doors and windows can be adjusted by the sealing adjustment mechanism 6.

[0026] Among them, in a possible implementation, the sealing adjustment mechanism 6 includes an adjusting slider 61 and an adjusting screw 62. The adjusting slider 61 is fixed with the limiting groove 111 on the vertical plate 11. By turning the adjusting screw 62, the adjusting slider 61 is driven to move horizontally along the limiting groove 111 to achieve sealing adjustment.

[0027] In a possible implementation, a boss 611 is provided on the back of the adjusting slider 61 , and the boss 611 is fixed to the limiting groove 111 by being clamped.

[0028] In a possible implementation, a bevel 612 is provided on the front of the adjusting slider 61 , and a latching position 51 adapted to the bevel 612 is provided at one end of the fan mounting rod 5 .

[0029] In a possible implementation, a slide groove 613 is provided on the adjusting slider 61 , and the adjusting slider 61 is fixed on the vertical plate 11 by means of rivets 9 cooperating with the screw holes 112 and the slide groove 613 on the vertical plate 11 .

[0030] The adjusting slider is riveted through the slide groove on the adjusting slider by rivets. There is a limit groove on the frame mounting seat. There is a boss on the adjusting slider. The boss is installed in the limit groove and cooperates with the above-mentioned slide groove so that the adjusting slider can translate on the frame mounting seat. There is an oblique screw hole on the adjusting slider. The adjusting screw is installed and turned. The adjusting screw pushes the slider out, and the translation displacement of the above adjusting slider can be adjusted.

[0031] Among them, in a possible implementation, the other end of the sash mounting rod 5 has an adjusting piece 7, and the adjusting piece 7 is fixed to the sash mounting rod 5 by a screw 10 and an eccentric rivet 8. Through the design of the adjusting piece, the eccentric rivet can be adjusted to drive the adjusting piece to move, thereby adjusting the lateral distance between the window sash and the hinge during the installation process.

[0032] Among them, the utility model of the sealing adjustable hinge is also provided with a gasket 12 between each hinge point. Through the setting of the gasket, the hinge can be prevented from being damaged by excessive friction during use, and the service life of the entire hinge can be extended.

[0033] See also Figure 1 As shown, there is an adjustment plate on the sash mounting rod, which is connected and fixed to the sash mounting rod by screws and eccentric nails. There is a sealing adjustment mechanism on the frame mounting seat. The sealing adjustment mechanism includes an adjusting slider and an adjusting screw. The adjusting slider is riveted to the vertical plate of the frame mounting seat, and there is an adjusting screw on the adjusting slider.

[0034] Among them, the working principle of the sealing adjustment mechanism is: there is a sliding groove on the adjusting slider, which is riveted to the screw hole on the vertical plate on the frame mounting seat, and there is a boss on the adjusting slider, which cooperates with the limit groove on the vertical plate of the frame mounting seat. By turning the adjusting screw on the adjusting slider, the adjusting slider can be displaced horizontally along the limit groove. There is an inclined surface on the adjusting slider, which cooperates with the card position of the sash mounting rod. When the adjusting slider is displaced toward the frame, it drives the sash mounting rod to press the sash edge against the frame, thereby improving the sealing of the door frame.

[0035] Moreover, based on the design of the sealing adjustment mechanism in the utility model, the adjustment range depends on the width of the fan edge fixing seat slot, the adjustment range is large, and the practicality is strong. Moreover, the contact position of the sealing adjustment mechanism is surface contact, wear-resistant, and effectively improves the service life.

[0036] In addition, it is easy to adjust through the screws installed on the frame mounting base. The installer does not need to squat or lean out of the window during adjustment, and the adjustment is safe and convenient.

[0037] In addition, when the hinge is in the closed state, the locking slope on the sash mounting rod is tightly aligned with the slope on the adjusting slider. By adjusting the translational displacement of the slider, the sash mounting rod drives the sash edge to be pressed toward the frame, thereby adjusting the sealing of doors and windows.

[0038] In combination with the drawings in the specification, the sealing adjustable hinge of the utility model includes a frame mounting seat, a first connecting rod, a second connecting rod, a third connecting rod, a sash mounting rod and a sealing adjustment mechanism, one end of the first connecting rod is hinged to one end of the frame mounting seat, the other end of the first connecting rod is hinged to one end of the third connecting rod, the middle of the first connecting rod is hinged to the middle of the second connecting rod, one end of the second connecting rod is hinged to the other end of the frame mounting seat, the other end of the second connecting rod is hinged to one end of the shaft sash mounting rod, the other end of the third connecting rod is hinged to the middle of the sash mounting rod, one end of the frame mounting seat is extended upwardly with a vertical plate, the sealing adjustment mechanism is arranged on the inner side of the vertical plate, and the sealing of the door and window can be adjusted by the sealing adjustment mechanism. Through such a structural design, the sealing of the hinge can be adjusted by the relative displacement of the sealing adjustment mechanism with respect to the vertical plate of the frame mounting seat to meet customer needs.

[0039] Moreover, the adjustable range of the seal depends on the width of the slide groove of the fan edge fixing seat. The adjustment range is large and the practicability is strong. The contact position of the adjustment mechanism is surface contact, wear-resistant, and can effectively increase the service life of the hinge.

[0040] The seal adjustment mechanism is designed on the frame mounting seat, which makes the adjustment more convenient, safe and convenient.

[0041] The sealing adjustable hinge of the utility model has a relatively simple adjustment mechanism, occupies a small space, is applicable to most existing door and window profiles, has no special requirements on the manufacturing process of the hinge bottom rod and the fixing rod, and can be manufactured using various common materials.

[0042] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
