Abstract

The invention relates to an adjustable hinge applied to a door and window. The adjustable hinge comprises a movable mounting body and a fixed mounting body, the fixed mounting body comprises a fixed base, a movable sliding block and a locking limiting block, a trapezoid transverse groove is formed in the fixed base, the movable sliding block is a trapezoid sliding block part, the movable sliding block is sleeved with the trapezoid transverse groove, a vertical groove transversely penetrating the trapezoid transverse groove is formed in the fixed base, a clamping groove is formed in the movable sliding block, one end of the locking limiting block is hinged into one end of the vertical groove, the middle of the locking limiting block is clamped in the clamping groove of the movable sliding block, a locking screw is arranged at the other end of the locking limiting block, a screw hole is formed in the bottom of the other end of the vertical groove, and the locking screw is locked into the screw hole. According to the hinge, the opening angle can be adjusted, after adjustment, 180-degree opening of a door and window sash can be achieved, actual use needs of people can be effectively met, and the hinge is simple in structure, easy to obtain, convenient to adjust, simple and easy to use.

Description

technical field [0001] The invention relates to the field of door and window accessories, in particular to a hinge. Background technique [0002] Most of the existing hinges are composed of a rotating shaft and two connecting plates. When the hinge is applied to the door and window leaves and door and window frames of doors and windows, the opening angle of the door and window leaves is fixed, and basically it can only be opened to an angle of 90-110 degrees. The door and window sash cannot be opened to a larger angle, and the opening angle cannot be adjusted according to actual needs. In practice, when people carry large items home, because the opening arc of the door leaf is too small, it will greatly affect the handling of the items, and it is easy to cause the door leaf and the door frame to be bumped, damaged or damaged. In addition, after the existing hinge is installed on the door leaf and the door frame, there is a hinge joint protruding or protruding between the do...

Problems solved by technology

[0002] Most of the existing hinges are composed of a rotating shaft and two connecting plates. When the hinge is applied to the door and window leaves and door and window frames of doors and windows, the opening angle of the door and window leaves is fixed. Basically, it can only be opened to an angle of 90-110 degrees. The doors and windows cannot be opened to a larger angle, nor can the opening angle be adjusted according to actual needs

In practice, when people carry large items home, because the opening arc of the door leaf is too small, it will greatly affect the handling of the items, and it is easy to cause the door leaf and the door frame to be damaged, damaged or damaged.

In addition, after the existing hinge is installed on the door leaf and the door frame, there is a hinge joint protruding or protruding between the door leaf and the door frame. This raised hinge joint will greatly affect the surface of the whole set of door products. Flatness, which in turn affects the harmonious appearance and grade of the whole set of door products

[0003] In addition, the existing hinge products, in order to increase their bearing capacity to the weight of the door leaf, are all solved by increasing their vertical dimension, which makes the hinge with stronger bearing capacity have a larger length, which in turn brings The most important thing is the raised hinge joint between the door leaf and the door frame, the longer and larger it is, the greater the impact on the surface smoothness of the whole set of door products
