Description

A kind of antifriction hinge

Technical field

The utility model is related to hinge technical field, more particularly, to a kind of antifriction hinge.

Background technology

People have been difficult to see wooden " door axis " in modern architecture, and the door and window of modern architecture is used mostly metallic door Axle hinge, the door-hinge hinge of modern production instead of ancient " door axis ", and the utility model in " door axis " this ancient times still retains On some old-fashioned door and windows of some 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 part.

Hinge is a kind of device for connecting or rotating, make door, lid or other tilting members can so as to rotate, generally by A pair of metal blades composition of pin connection.

Ready-made hinge is used for cupboard door, window, door etc., and material has irony, copper and stainless steel.The shortcoming of ready-made hinge is Function without spring hinge, various collision beads must be loaded on after installing hinge, and otherwise wind can blow door-plate.

Tobacco pipe hinge, is also spring hinge.It is mainly used in the connection of furniture door plate, it typically requires that plate thickness is 16~20 Millimeter, material has 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 having respective hinge to match, various cabinet doors are made to have corresponding range of extension.

Gate hinge, point plain edition and bearing type said before plain edition, and bearing type can divide copper, no from material Rust steel.From the point of view of current consumption, from the more of copper bearing hinge, because its is attractive in fashion, beautiful, price is fitted In, and it is equipped with screw.

Wherein, ready-made hinge is typically all inserted in shaft hole shaft core during use, makes the rotatable company of hinge Connect, be then pressed into tack at the two ends of hinge, but, due to being form that face contacts between the shaft core and the shaft hole, So when hinge rotates, very big frictional force can be produced, it is permanent in this way, very big shadow can be produced to the life-span of hinge Ring, also, during door carries out folding, can also produce the friction sound, influence is used.

At present, in order to eliminate the influence that this frictional force is produced, the service life of hinge is improved, is typically all commonly being closed Resistance oil is added in the shaft core of page, then in shaft hole is inserted, frictional force is eliminated by the lubricity of resistance oil, but, Addition resistance oil even lubricating oil is lubricated by way of auxiliary, eliminates the frictional force produced when hinge rotates, And hinge is in itself that, without the characteristic of frictional force is alleviated, once forgetting addition resistance oil or addition not in time, hinge revolves Turn by frictional force hinge still can be caused to produce abrasion, and then reduce the service life of hinge.

Utility model content
