Description

Pivoted arm door hinge

(I) technical field

The utility model relates to a rocking arm hinge belongs to five metals class product.

(II) background of the invention

Hinges are an important component of door products. The existing rotating arm hinge for the anti-theft door has the common axial gasket fixing mode and no radial shaft sleeve, so that when the hinge bears load, the rotating arm and the gasket plane and the spindle and the rotating arm shaft hole have severe friction, and the hinge has long time and can make squeak noise. In addition, the market demand for high-grade security doors in recent years is increasing the adoption of concealed hinges. The concealed hinge is generally a rotating arm hinge with a rotating shaft on a door frame, generally, the rotating arm hinge is composed of a plurality of parts, and a rotating arm box is connected with the door frame in a welding mode. The structure is unreasonable, the installation and debugging of the door leaf are troublesome, the rigidity of the rotating arm is poor, and the door leaf is easy to droop. Especially, in the case of an aluminum alloy door frame structure, the rotating arm box cannot be welded with the door frame. Therefore, the rotary arm door hinge which can be used for an aluminum alloy door frame structure, is convenient to assemble, debug and install, is slightly loose and flexible to open, has no noise and can bear a heavy door leaf is increasingly important.

Disclosure of the invention

Based on above-mentioned product defect and requirement, the to-be-solved technical problem of the utility model is that simple to operate, open more pine flexibility, noiselessness, can bear a rocking arm hinge structure of heavy door leaf again.

The following is the technical proposal adopted by the utility model:

a pivoted arm door hinge is composed of pivoted arm module and door leaf pivoted arm fixing seat module. The rotating arm assembly consists of a rotating arm, an upper rotating arm support leg, a lower rotating arm support leg, a rotating shaft, a plane bearing and a door leaf rotating arm fixing seat assembly. The door leaf rotating arm fixing seat assembly is provided with at least two open square inserting holes and a square safety screw hole in a connecting part with the rotating arm, and a fixing screw of the door leaf rotating arm fixing seat assembly is in clearance fit with the open square inserting holes and the square safety screw hole from top to bottom and from left to right. Two directional position adjustments can be adjusted. The rotating arm is connected and fixed on the door leaf rotating arm fixing seat component through a fixing pressure plate, a fixing screw and a flat head set screw. The position adjustment of the rotating arm component in the up-down direction, the left-right direction and the like can be at least realized.

The rotating arm is connected with two shaft holes of the upper rotating arm support leg and the lower rotating arm support leg through rotating shafts with shoulders at two ends and is riveted on the end surfaces of the two shaft holes, and a plane bearing is arranged at the butt surfaces of the two shaft holes of the rotating arm and the upper rotating arm support leg and the lower rotating arm support leg, and is composed of a shaft sleeve and a supporting gasket or adopts a shaft sleeve and ball plane bearing type structure. This patent prefers a bushing and support washer configuration. The shaft sleeve is designed to avoid direct friction between the shaft hole and the shaft, and abnormal sound is easy to occur after a long time. The bearing gasket is used for avoiding the direct friction between the abutting surfaces of the shaft sleeve and the rotating arm box, and the bearing gasket is provided with small oil storage holes for lubricating the abutting surfaces of the rotating arm box. The rotating arm can rotate easily and flexibly when being loaded, the function of a plane bearing is realized, and the bearing capacity of the rotating arm hinge is improved.

In addition, the upper rotating arm support leg and the lower rotating arm support leg are designed into L-shaped support legs which are correspondingly and symmetrically manufactured and installed, and two long-waist-shaped circular installation holes which are perpendicular to the axial lead of the rotating shaft and do not intersect are formed in the L-shaped support leg installation plate. Through the long waist round mounting hole, the position of the rotating arm assembly can be adjusted along the direction of the long waist round mounting hole when the rotating arm assembly is mounted.

The utility model has the advantages that: the door leaf is flexible and easy to open, strong in bearing capacity, attractive in appearance and convenient to assemble and disassemble the rotating arm assembly (door frame) and the door leaf rotating arm fixing seat assembly (door leaf).

(V) specific embodiment

The present invention will be further described with reference to the accompanying drawings 1-3, in conjunction with the embodiments. The pivoted arm door hinge mainly comprises a pivoted arm assembly and a door leaf pivoted arm fixing seat assembly. The rotating arm assembly consists of a rotating arm (1), an upper rotating arm support leg (2), a lower rotating arm support leg (3), a rotating shaft (4), a plane bearing (5) and a door leaf rotating arm fixing seat assembly (6). The connecting part of the door leaf rotating arm fixing seat assembly (6) and the rotating arm (1) is provided with at least two open square inserting holes (1-2) and one square safety screw hole (1-3), and a fixing screw (6-3) of the door leaf rotating arm fixing seat assembly (6), the open square inserting holes (1-2) and the square safety screw holes (1-3) are in clearance fit from top to bottom and from left to right. Two directional position adjustments can be adjusted. The rotating arm (1) is connected and fixed on the door leaf rotating arm fixing seat component (6) through a fixed pressing plate (6-2), a fixed screw (6-3) and a flat head set screw (6-4).
