Description

Double-shaft rotating arm hinge

Technical Field

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

Background

The rocker arm hinge is an important component of door products. The existing common rotating arm hinge for the anti-theft door has a rotating shaft which is arranged in an inner cavity of a door frame in a concealed installation and fixing mode. The door leaf mounting seat and the rotating arm are fixedly mounted and connected by a plurality of screws and are not easy to detach and mount. In addition, the market demands for high-grade security doors in recent years, more and more applications for concealed hinges are being increasingly applied. The concealed swivel arm hinge is a swivel arm hinge with a single-shaft structure and a rotating shaft in an inner cavity of a door frame, and is generally called a swivel arm hinge. The rotating arm box and the door frame are connected in a welding mode and can not be disassembled and assembled. The structure is unreasonable, the installation and debugging of the door leaf are troublesome, the rigidity of the rotating arm is poor, the door leaf is easy to droop, and the opening angle of the door leaf can only reach about 120 degrees at most. Therefore, the rotary arm hinge which is convenient to assemble, debug and install and flexible to open and can enable the opening angle of the door leaf to reach 180 degrees is more and more important to develop and design.

And further: the door leaf hinge connecting plate component consists of a door leaf hinge plate, a set screw, a rotating shaft B and a plane gasket B. The door leaf hinge connecting plate component is connected with the end D of the shaft hole in the rotating arm hinge component through the fixed rotating shaft B, the ends B of the upper shaft hole and the lower shaft hole of the door leaf hinge plate are provided with mounting screw holes for mounting set screws, the rotating shaft B penetrates through the shaft hole B of the door leaf hinge plate and the shaft hole C of the rotating arm, and the rotating shaft B is fixedly fixed at the two ends of the shaft hole B of the door leaf hinge plate through the set screws or riveting or welding, so that the bearing capacity of the door leaf hinge plate can be improved, and the rotating shaft B and the door leaf hinge plate can be prevented from rotating relatively. The plane gasket B is arranged on the inner sides of the upper shaft hole B and the lower shaft hole B and is fixedly installed with the rotating shaft B.

Further: the rotating arm assembly consists of a rotating arm, a shaft sleeve A, a shaft sleeve B and a positioning steel ball assembly. The shaft sleeves A are tightly matched and installed at two ends of a shaft hole C of the rotating arm, the middle part of the excircle of the shaft hole C of the rotating arm is at least provided with an outward boss A, and a screw hole A is formed in the outward boss A and is provided with a positioning steel ball assembly to enable the rotating arm to rotate in place for positioning; the shaft sleeves B are tightly installed at two ends of a shaft hole D of the rotating arm in a matching mode, the middle portion of the excircle of the shaft hole D of the rotating arm is at least provided with two outer bosses B which are back to the bosses A, and the outer bosses B are provided with screw holes B which are provided with positioning steel ball assemblies to enable the rotating arm to rotate in place for positioning.

Further: the door leaf hinge plate is characterized in that a set of long mounting holes and two screw holes C are at least formed in the mounting plate of the door leaf hinge plate, T-shaped threaded support legs are mounted on the two screw holes C, and the door leaf hinge plate can be adjusted in two directions, namely, up and down or left and right in the front and back direction when being mounted with a door leaf.

Further: the rotating shaft A and the rotating shaft B correspond to the positions of the positioning steel ball assemblies, and steel ball positioning holes are formed in the outer circle of the shaft to limit the angular positions of the positioning door leaf hinge plate and the rotating arm, the rotating shaft A and the rotating shaft B.

Compared with the combination of the plane gasket A and the plane gasket B with the end face of the T-shaped shaft sleeve, the bearing capacity and the service life of the steel ball plane bearing are stronger and longer.

In sum, the double-shaft rotating arm hinge has the advantage that the door leaf is convenient to mount and dismount. The combination of the gasket and the shaft hole sleeve enables the rotating arm hinge to rotate easily and flexibly during loading, plays a role of a plane bearing, and has stronger bearing capacity and longer service life compared with a steel ball plane bearing. In addition, the two ends of the rotating shaft of the rotating arm assembly are fixedly connected with the end face shaft holes of the door frame mounting seat or the door frame hinge plate into a whole by riveting or welding, so that the bearing capacity of the door frame mounting seat or the door frame hinge plate is enhanced, and the rotating arm hinge is prevented from sagging under stress. Due to the double-shaft structure, the opening angle of the door leaf can be 180 degrees, and the opening angle of the first shaft (rotating shaft A) of the door frame is not enough to compensate the opening angle through the second shaft (rotating shaft B) of the door leaf edge.
