Description

A kind of hinge

Technical field

The utility model relates to a kind of hardware article field, refers to a kind of hinge that is used on the door and window especially.

Background technology

The hinge that uses on the existing door and window all adopts the two-fold formula hinge structure of symmetry, and the hinge of this kind structure has following drawback in long-term use:

When 1, installing, the workman need excavate slot respectively on door leaf and doorframe, so just has the paint that coats on damage doorframe and the door.

2, Kai Wa slot not necessarily meets standard, shallow also needs to add deep trouth again, the dark cushion material that also needs, and hinge also will fill the paint of damage after installing, and so both time-consuming taking a lot of work increased cost again.

The utility model content

The purpose of this utility model is to provide a kind of hinge, and it is simple in structure and easy for installation.

To achieve these goals, technical solution of the present utility model is: a kind of hinge, it is formed by the mandrel hinge joint by main hing straps and secondary leaf of hinge.

The middle part of main leaf of hinge has one can be placed in wherein groove for secondary leaf of hinge, and this flute profile is identical with secondary leaf of hinge shape.

Offer one group of circular hole that supplies screw to place on the major and minor hing straps respectively.

Offer 4 circular holes that supply screw to place on the main hing straps.

Offer 4 circular holes that supply screw to place on the secondary hing straps.

Main hing straps are identical with secondary hing straps thickness.

Mandrel is provided with two pads.

After adopting such scheme, the utility model when mounted can be according to size, the weight of the door that will fix, optionally use screw quantity, hing straps are installed on door and the doorframe, the workman need not excavate slot when mounted again on door leaf and doorframe, must not damage simultaneously finished product paint, install the time and labour saving, attractive in appearance simple and direct.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is the utility model three-dimensional exploded view;

Fig. 2 is the utility model three-dimensional combination figure;

Fig. 3 is the utility model turn-off position stereogram.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model hinge is formed by mandrel 3 hinge joints by main hing straps 1 and secondary leaf of hinge 2.

Main leaf of hinge 1 middle part has one can be placed in wherein groove 11 for secondary leaf of hinge 2, and this groove 11 is identical with secondary leaf of hinge 2 shapes.

Offer 4 circular holes 12 that supply screw to place on the main hing straps 1.

Offer 4 circular holes 21 that supply screw to place on the secondary hing straps 2.

Main hing straps 1 are identical with the thickness of secondary hing straps 2.

Mandrel 3 is provided with two pads 4.

When installing, with main leaf of hinge 1 card in the doorframe place, after passing circular hole 12 on the main hinge blade 1 by screw, main hinge blade 1 is positioned doorframe, in addition with secondary hing straps 2 cards on door, after also passing circular hole 21 on the secondary leaf of hinge 2, secondary hing straps 2 are positioned so just to have installed on the door with screw.

As shown in Figure 3, because main leaf of hinge 1, secondary leaf of hinge 2 all are serve as that axle rotates with mandrel 3, so it can rotate 360 degree, mutually noninterfere, thereby can freely rotate.

The utility model when mounted can be according to size, the weight of the door that will fix, optionally use screw quantity, hing straps are installed on door and the doorframe, the workman need not excavate slot when mounted again on door leaf and doorframe, must not damage simultaneously finished product paint, installing the time and labour saving, attractive in appearance simple and direct.
