Description

Hinge seat and cabinet door using the hinge seat

technical field

The invention relates to a hinge base and a cabinet door using the hinge base.

Background technique

The existing hinge base is usually made of steel material, and the surface of the hinge base needs to be treated with anti-rust treatment, and the processing procedure is complicated. The hinge seat of the cabinet door is installed on the door frame through bolts. Only the side of the mounting surface of the hinge seat is stressed, and the hinge seat is only subjected to force in the front and rear directions on the side of the installation surface. The hinge seat will rotate around the axial direction of the bolt. The precision is limited, and the installation strength is poor, the installation is not reliable, and it is easy to loose; because the hinge seat is usually installed on the surface of the column, when the cabinet door is closed, the hinge seat usually leaks out.

Contents of the invention

The purpose of the present invention is to provide a hinge seat to solve the problem of poor installation accuracy of the existing hinge seat. The present invention also provides a cabinet door using the above-mentioned hinge seat.

In order to achieve the above object, the cabinet door of the present invention adopts the following technical scheme: the cabinet door includes a column, the column is provided with a hinge seat, the hinge seat has a connection part connected with the column, the connection part is provided with a bolt connection hole, the connection part An anti-swing structure for preventing the hinge base from swinging around the axis of the bolt connection hole is also provided on the upper column, and an anti-swing matching structure corresponding to the anti-swing structure is provided on the column.

The anti-swing structure and the anti-swing matching structure slide and guide along the extension direction of the column.

One of the anti-swing structure and the anti-swing matching structure includes a dovetail groove, and the other includes a dovetail-shaped protrusion that cooperates with the dovetail groove. assembled together.

There is a blocking wall protruding toward the inside of the cabinet door on the peripheral edge of the column, and the hinge seat is covered by the blocking wall.

The hinge base includes a chain lug and a detent key that is engaged with the upright to prevent the hinge base from rotating around the axis of the chain lug.

In order to achieve the above object, the hinge seat of the present invention adopts the following technical scheme: the hinge seat has a connection part for connecting with the column, the connection part is provided with a bolt connection hole, and the connection part is also provided with a bolt connection hole for preventing the hinge seat from wrapping around the bolt. The anti-sway structure of the axis swing.

The anti-swing structure is a convex part and/or a concave part provided on the connecting part of the hinge base.

The anti-swing structure includes the protrusion, and the protrusion forms a slider structure for sliding and guiding cooperation with the corresponding column.

The slider structure is in the shape of a dovetail.

The hinge base includes a chain lug and a detent key that is engaged with the upright to prevent the hinge base from rotating around the axis of the chain lug.

Beneficial effects of the present invention: the connecting part is provided with an anti-sway structure, and the column is provided with an anti-sway matching structure corresponding to the anti-sway structure, and the hinge seat is limited in multiple directions, which can prevent the hinge seat from wrapping around the bolt connection hole The axis of the hinge swings, which improves the installation accuracy of the hinge seat, prevents the hinge seat from loosening, and is securely installed.

Further, since the anti-swing structure and the anti-swing matching structure slide and guide along the extension direction of the column, the installation of the hinge seat can be facilitated.

Further, the upright column and the hinge seat are assembled together through the dovetail groove and the dovetail protrusion to prevent the hinge seat from coming off, and the pre-installation of the hinge seat can be realized.

Further, the retaining wall can cover the hinge seat, preventing the hinge seat from leaking outside when the cabinet door is closed.

Further, the anti-rotation key can prevent the hinge seat from rotating around the axis of the chain ear, and prevent the hinge seat from loosening.
