Abstract
The utility model discloses a point contact hinge which relates to the field of the connecting piece of the door and the door case with preponderant weight. The presently universal hinge is only suitable to the connection between the door and the door case with lighter weight whose strength is not high and the turning adaptability is unsatisfactory. In order to solve the problem, the utility model adopts the structures of the hinge arm and the hinge pin. The hinge pin is provided with an iron shot while a height-resizing set screw is arranged on the hinge arm, the weight of the door is vertically transmitted to the door case via the point-contact between the height-resizing set screw and the iron shot so that the hinge of the point contact hinge has the characteristics of high strength and fine adaptability. The point contact of the utility model is suitable for the connection between the door and the door case with preponderant weight, and with a wear-resistant sleeve and a wear-resistant pad arranged between the tumblers, the wearing-out is reduced and the service life is prolonged.
Description
Technical field
The utility model relates to door and doorframe connector field, especially is applicable to the hinge of heavier door usefulness.
Background technology
Door generally is connected by hinge-type hinge with the flexible connection of doorframe, and this hinge is applicable to the common door that weight is lighter, and supply mainly is this class hinge in the market.Expansion along with mankind's activity, some doors that are not only thick but also weight occur in succession, as bank exchequer door, dangerous cargo warehouse door, security personnel's protective door etc., adopt the steel structure concrete manufacturing mostly, door like this should not be again with common hinge connection, otherwise can cause hinge to rupture or rotate flexibility and reduce greatly because of insufficient strength, satisfy the requirement of this respect so must design novel hinge.
Summary of the invention
The purpose of this utility model provides a kind of point contact type hinge that thick heavy door uses that is suitable for higher-strength and flexibility.
Realize that the above-mentioned purpose technical scheme is as follows: the point contact type hinge, have pivoted arm and hinge pin, pivoted arm is fixed on the door, and hinge pin is fixed on the doorframe and the corresponding position of pivoted arm.In the upper end of hinge pin is cylinder, has the circular cone hole in cylindrical end, circular cone hole axis is consistent with cylinder axis, in the circular cone hole, be placed with steel ball, the part of steel ball is exposed to outside the circular cone hole, at the pivoted arm end downside adjacent with hinge pin, have cylindrical groove with the cylindrical correspondence position of hinge pin, pivoted arm is sleeved on the hinge pin cylinder by cylindrical groove, in pivoted arm cylindrical groove bottom and steel ball contact position, axially have and adjust the height top wire hole, top wire hole penetrates on the upper side of pivoted arm, in adjusting the height top wire hole, be equipped with and adjust the height jackscrew, adjust the height jackscrew and contact with steel ball.
Be with wear-resistant sleeve between hinge pin cylinder and the pivoted arm cylindrical groove, between at the bottom of steel ball and the cylindrical groove, wear-resistant pad be housed.
The top wire hole sidewall has the oil sealing top wire hole adjusting highly, is screwed with the oil sealing jackscrew in the oil sealing top wire hole.
The steel ball that is in use in the hinge pin circular cone hole contacts with adjustment height jackscrew wear-resistant pad point down in being in the pivoted arm cylindrical groove, weight be delivered to doorframe by this contact point, also to put with this at closing time be the axle center rotation opening.Wear-resistant pad between the wear-resisting cushion cover between hinge pin cylinder and the pivoted arm cylindrical groove and steel ball and Height Adjustment jackscrew plays effect anti-wear, that increase the service life.Lubrication oil joins rotary moveable position, lubricate by the oil sealing top wire hole.
The utlity model has the intensity height, flexibility is good and the characteristics of long service life, can adjust the height of door by adjusting the height jackscrew during assembling, easy for installation saving trouble, good manufacturability, the door that is suitable for not only thick but also heavy special purpose uses.
