Description
Technical field
The utility model relates to hinge fields, and in particular to a kind of hinge assembly.
Background technique
Hinge is a kind of articulation piece of door and window common in daily life, is mainly used for the moving process of door and window, common
Hinge is all made of metal material and is made, and hinge is directly rotatablely connected with hinge axis, if hinge is not used for a long time,
Hinge or hinge axis may can get rusty, and lead to occur rust staining between hinge and hinge axis, occur in rotation process abnormal sound or
Person can not normal rotation carry out door and window folding work, if hinge frequency of use is excessively high, it is also possible to will appear hinge and hinge
Cooperation loosen, axis runout causes door and window that can not be normally carried out folding, and hinge will be scrapped, and can not reuse, simultaneously
Hinge mounting hole on door, window and doorframe is because of the reason of dismantling, it is difficult to reuse, so that door, window and doorframe receive
It is difficult to the damage restored, firmness is affected.
Summary of the invention
The technical problems to be solved in the utility model is to overcome present technological deficiency, provides a kind of hinge and hinge
Axis is not in a kind of hinge assembly of abnormal sound, easy to install, quick detachable, easy replacement part of damage during rotation.
The technical solution of the utility model is to provide a kind of hinge assembly, including the first hinge, the second hinge and hinge
Axis, the first hinge include first connecting portion, and the second hinge includes second connecting portion, it is characterised in that: and it further include two axle sleeves, one
A axle sleeve and first connecting portion circumferentially limit grafting, and rotate and be socketed with one end of hinge axis, another described axle sleeve with
Second connecting portion circumferentially limit grafting, and rotate and be socketed with the other end of hinge axis, the axle sleeve is plastic part.
The utility model has the following beneficial effects: axle sleeve is placed on rotation axis and is connected with first using high-intensitive wear-resistant plastic
