Description

Rocking arm hinge

Technical Field

The utility model relates to a 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 adopts a common rotating shaft direction hinge as an installation and fixing mode, and a door leaf installation seat and a rotating arm are fixedly installed and connected by a plurality of screws and are not easy to disassemble and assemble. In addition, in recent years, the market demands high-grade security doors, and the adoption of concealed hinges is increasing. The concealed hinge is generally a rotating arm hinge with a rotating shaft on a door frame, and is generally called as a rotating arm hinge, and a rotating arm box and the door frame are connected 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. Therefore, the hidden hinge for the rotating arm is more and more important for developing and designing the hidden hinge for the heavy door leaf, which is convenient to assemble, debug and install, is opened more flexibly and can bear the heavy door leaf.

SUMMERY OF THE UTILITY MODEL

Based on the above product defects and requirements, the to-be-solved technical problem of the utility model is to provide a rocking arm blind hinge structure.

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

a rotating arm hinge is composed of a rotating arm assembly, a door frame hinge plate, a rotating shaft and a gasket. The outer extension portion of the rotating arm assembly is provided with a group of opening insertion grooves and at least one closed long connecting hole, the rotating shaft penetrates through shaft holes of the door frame hinge plate and the rotating arm assembly and is riveted or welded on the outer end faces of the shaft holes at the upper end and the lower end of the door frame hinge plate, and the gaskets are arranged on the inner end faces of the shaft holes at the upper end and the lower end of the door frame hinge plate.

Further: the rotating arm assembly consists of a rotating arm and a shaft hole sleeve, and the shaft hole sleeve is tightly installed at two ends of a rotating arm shaft hole in a matching mode.

Further: the outer extension part connected with the door leaf and the outward extension surface of the circle rolling hole part of the rotating arm are at least provided with a section of arc surface concentric with the rotating shaft to form an arc groove.

Further: the door frame hinge plate is provided with a yielding notch of the arc-shaped surface of the rotating arm, and a group of mounting holes for connecting the door frame hinge plate and the door frame are arranged on two sides of the yielding notch.

In summary, the rotating arm of the rotating arm hinge is provided with a group of opening insertion grooves and at least one closed long connecting hole, so that the door leaf hinge 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 when being loaded, plays a role of a plane bearing and improves the bearing capacity of the rotating arm hinge. In addition, two ends of the rotating shaft of the rotating arm hinge are riveted or welded with the end face shaft holes of the doorframe hinge plate to be fixed into a whole, so that the bearing capacity of the rotating arm hinge is increased, the force sagging of the rotating arm hinge is prevented, and the service life of the hinge is prolonged.
