Description

Three-wing vertical hinged door hinge

Technical Field

The utility model is suitable for the technical field of assistance for a vertical hinged door, and particularly relates to a three-wing vertical hinged door hinge.

Background

At present, the vertical hinged door hinge is mainly used for connecting a door frame part and a door leaf part of a vertical hinged door, and is particularly used for a multi-seal frame-packaged leaf type outward vertical hinged door with a wide application range.

According to a patent (publication number "CN 109972952B"), a hinge limit structure includes: the hinge comprises a hinge seat, a hinge shaft connected with the hinge seat and a positioning piece connected with the hinge seat. The hinge seat is provided with a shaft hole. The hinge seat is also provided with a plug hole communicated with the shaft hole. The hinge shaft passes through the shaft hole. The positioning piece comprises: a main body and a holding column connected with the main body; the main body is arranged in a plastic material structure and connected to the hinge seat; the abutting column is positioned on one side of the main body facing the hinge shaft; the abutting column extends into the shaft hole from the inserting hole and abuts against the hinge shaft; the abutting column is used for feeding back abutting force between the abutting column and the hinge shaft to drive the main body to deform, and the main body deforms to generate pressing force reacting on the hinge shaft. Above-mentioned hinge limit structure, when hinge axle and hinge seat equipment, along with the in-process in the shaft hole that the hinge axle inserted the hinge seat, the main part of ordering about the setting element is out of shape and is produced the reaction force in order to compress tightly the hinge axle, under the prerequisite of the assembly stability problem between solution hinge axle and the hinge seat, improves the packaging efficiency.

However, there are still some disadvantages in the above patents: when the rotatability of the hinge is limited, the positioning piece is deformed to generate corresponding reaction force, so that the positioning piece is pressed to position the hinge shaft, and the positioning piece is easily broken and damaged due to repeated deformation for a plurality of times in the long-time repeated use process, so that subsequent use is influenced, and when the hinge is used, the limitation on the hinge and the rotatability cannot be quickly carried out. Therefore, we propose a three-wing vertical hinged door hinge.
