In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a door and window hinge of adjustable elasticity, includes fixing base, first cantilever, second cantilever, third cantilever and trailing arm, the both ends of first cantilever and second cantilever are articulated with fixing base and trailing arm respectively, the sliding tray has been seted up along length direction on the second cantilever, the activity is provided with the tight regulation subassembly in the sliding tray, the one end and the tight regulation subassembly of third cantilever are articulated, and the other end is articulated with the fixing base, the tight regulation subassembly includes first slider, second slider and fixed screw, first slider and second slider set up the upper and lower place at the sliding tray respectively, the fixed screw is through passing first slider fixed connection second slider.

Furthermore, one end of the first sliding sheet and one end of the second sliding sheet are provided with hinge holes, rivets are arranged in the hinge holes, and the rivets penetrate through the first sliding sheet and the second sliding sheet to hinge the third cantilever.

Further, the width of the first sliding sheet and the width of the second sliding sheet are both larger than the width of the sliding groove.

Further, the bottom of fixing base is provided with the fixture block, the fixture block passes through adjusting screw and connects the fixing base.

Compared with the prior art, the beneficial effects of the utility model are that: through having seted up the sliding tray along length direction on the second cantilever, and through by first slide, the tightness adjusting part is constituteed to second slide and fixed screw, when wrench movement fixed screw made first slide and second slide correspond the second cantilever and press from both sides tightly, make articulated tightness adjusting part's third cantilever unable the removal, when wrench movement fixed screw made first slide and second slide correspond the second cantilever and loosen, the third cantilever is portable smooth and easy, thereby realize the elasticity when control door and window hinge opened and shut.
