Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to an adjustable hinge base. Background Art

[0002] When the hinge is used in conjunction with doors and windows, in order to ensure that the hinge can work normally, it is necessary to use a hinge base to support and fix the hinge on the door and window. The traditional hinge base usually includes a base and an adjustment component arranged in the base. The adjustment component is arranged on the side wall of the base. The adjustment member on the adjustment component extends into the limit groove of the base to adjust the side wall of the base and the connection. However, since the side wall of the base is adjusted by the adjustment member and the contact surface of the door and window connected, a gap is generated between the side wall and the contact surface, which easily causes the hinge base and the door and window to be connected to become loose, thereby reducing the stability of the hinge in conjunction with the door and window.

[0003] Therefore, the utility model provides an adjustable hinge base that cooperates with the door and window adjustment through the built-in bottom plate. Summary of the invention

[0010] Furthermore, the base bottom shell is provided with waist-shaped holes located on both sides of the boss and corresponding to the through holes on the upper end plate. By installing up and down adjustment screws connected to the through holes on the bottom plate in the two waist-shaped holes, the position of the base bottom shell on the door and window can be adjusted up and down.

[0011] Furthermore, the adjustment groove of the base bottom shell for the eccentric nail countersunk hole is waist-shaped. When the eccentric nail rotates, the position of the bottom plate in the base bottom shell is adjusted left and right, thereby achieving the purpose of left and right adjustment of the connection between the doors and windows.

[0012] Furthermore, a guide groove is provided on one side of the base bottom shell corresponding to the adjustment groove, and a guide plate is provided on the lower end plate at the lower right part of the bottom plate to cooperate with the guide groove. The guide plate is located in the guide groove to guide the left and right movement of the bottom plate on the base bottom shell through the rotation of the eccentric nail, thereby maintaining the stability of the bottom plate in the base bottom shell so that it can be adjusted left and right according to usage needs.

[0013] Furthermore, the guide plate is connected to the lower end plate in a U-shape, and the U-shaped guide plate passes through the guide groove and is hooked and limited with the guide groove to maintain the firmness of the connection between the bottom plate and the bottom shell of the base.
