Description
Technical field
The present invention relates to hinge technical field, more particularly, to a kind of bearing type oil-free hinge.
Background technology
People have been difficult to see wooden " door axis " in modern architecture, and the door and window of modern architecture uses metallic door mostly
Axis hinge, for the door-hinge hinge of modern production instead of ancient " door axis ", the invention in " door axis " this ancient times remains in one
On some old-fashioned door and windows of a little ancient buildings and Guanzhong area civil construction.
Hinge also known as hinge, formal name are hinge, and two foldings of normal composition are two parts of attached article and can be allowed to living
Dynamic component.
Hinge is a kind of device for connecting or rotating, make door, lid or other tilting members can so as to rotate, usually by
A pair of of metal blade composition of pin connection.
For ready-made hinge for cupboard door, window, door etc., material has irony, copper and stainless steel.The shortcomings that ready-made hinge is
Function without spring hinge must be loaded on various collision beads after installing hinge, and otherwise wind can blow door-plate.
Tobacco pipe hinge, is also spring hinge.It is mainly used for the connection of furniture door plate, it is 16~20 that it, which generally requires plate thickness,
Millimeter, material have galvanized iron, a kirsite, and spring hinge has adjusting screw, can up and down, the height of left and right adjusting plate, thickness；
Its feature is can to coordinate cabinet door opening angle, in addition to general an angle of 90 degrees, 127 degree, 144 degree, 165 degree according to space
Deng there is respective hinge matching, various cabinet doors is made to have corresponding range of extension.
Gate hinge divides plain edition and bearing type, had been said before plain edition, and bearing type can divide copper, no from material
Become rusty steel.From the point of view of current consumption, the more of copper bearing hinge is selected, because its is attractive in fashion, beautiful, price is fitted
In, and it is equipped with screw.
Wherein, steel core is typically inserted into shaft hole during use, makes the rotatable company of hinge by ready-made hinge
It connects, still, due to being form that face contacts between the steel core and the shaft hole, simultaneously because hinge also needs to bear a weight
The axial force of generation so when hinge rotates, can generate very big frictional force, for a long time in this way, can be to the service life of hinge
It has a huge impact, also, during door carries out folding, can also generate the friction sound, influence to use.
At present, in order to eliminate the influence that this frictional force generates, the service life of hinge is improved, is typically commonly being closed
Resistance oil is added in the steel core of page, then in shaft hole is inserted into, frictional force is eliminated by the lubricity of resistance oil, still,
Addition resistance oil even lubricating oil is lubricated by way of auxiliary, eliminates the frictional force generated during hinge rotation,
And hinge is not have the characteristic for alleviating frictional force in itself, once forget to add resistance oil or addition not in time, hinge rotation
Turn to be subject to frictional force that hinge still can be caused to generate abrasion, thereby reduce the service life of hinge.
The content of the invention
It is an object of the invention to provide a kind of bearing type oil-free hinges, are revolved with solving hinge in the prior art
The technical issues of transferring from a team to another and generate frictional force, reducing the service life of hinge.
