Abstract
The utility model discloses a heavy duty hinge, which comprises a hinge support, a pin shaft, a frame-shaped hinge body fitted over the pin shaft, a fan-shaped hinge body connected to the frame-shaped hinge, and a bearing between the shaft sleeve of the frame-shaped hinge body and the pin shaft.. In the technical scheme, with the bearing arranged between the shaft sleeve and the pin shaft, the dry friction between the shaft sleeve and the pin shaft is replaced with rolling friction; therefore, smoothness of door leaf rotation can be improved, noise and abrasion can be reduced, and the service life of the burglary-resisting door can be increased..
Description
Technical field
The utility model belongs to the hinges of door and window field, particularly relates to a kind of heavy hinge that is used for security door.
Background technology
In the prior art, after security door door leaf and doorframe combination were closed, the door leaf hinge did not expose, and this hinge load-bearing is big, so be heavy hinge.Existing heavy hinge, comprise rocker bar bearing, bearing pin, frame face hinge bodies, covering of the fan hinge bodies, frame face hinge bodies is provided with axle sleeve, and axle sleeve is set on the bearing pin, be provided with plane bearing between axle sleeve bottom and rocker bar bearing, frame face hinge bodies is connected by screw with the covering of the fan hinge bodies.Opening at closing time, frame face hinge bodies and covering of the fan hinge bodies are rotated around bearing pin, axle sleeve and bearing pin dry friction, and because the security door door leaf is heavier easily sagging, so at rotation process, the easy unbalance stress of axle sleeve and bearing pin, easily rotate dumb, abnormal sound and wearing and tearing are arranged, even cause that door leaf is sagging can't normally be opened.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model provides a kind of heavy hinge, is intended to improve the degree of flexibility that door leaf rotates, and reduces abnormal sound and wearing and tearing, thereby prolongs the application life of security door.
To achieve the above object, the utility model has adopted following technical scheme:
A kind of heavy hinge comprises rocker bar bearing, bearing pin, is set with frame face hinge bodies on the bearing pin, and frame face hinge bodies connects the covering of the fan hinge bodies, is provided with bearing between the axle sleeve of described frame face hinge bodies and the bearing pin.
As preferably, in the above-mentioned axle sleeve up and down two ends respectively be provided with a bearing, described bearing is a needle bearing.Between axle sleeve and bearing pin, set up needle bearing, make axle sleeve and pin bearing recuperation, rotate more flexibly, reduced abnormal sound and wearing and tearing to disperse distribution.
As preferably, above-mentioned frame face hinge bodies with the superimposed face of covering of the fan hinge bodies on be provided with rectangular channel, a square neck screw passes frame face hinge bodies successively and is connected with nut thread with the covering of the fan hinge bodies, the square neck position of described square neck screw and rectangular channel fasten.Square neck screw and rectangular channel correspondingly are set can not rotated when mounted, can conveniently locate assembling.
As preferably, above-mentioned frame face hinge bodies is connected with four screw by the square neck screw with the covering of the fan hinge bodies.Staggered fixing more solid and reliable with respect to existing three screws.
Above-mentioned bearing pin lower end is arranged with plane bearing, the axle sleeve lower end that offsets above the plane bearing, and rocker bar bearing offsets below the plane bearing.
The utility model is owing to adopted above technical scheme, by between axle sleeve and bearing pin, setting up bearing, replaced original dry friction between the two by rolling friction, improved the degree of flexibility that door leaf rotates, reduce abnormal sound and wearing and tearing, thereby prolonged the application life of security door.
