Hinge device

Abstract

The invention discloses a hinge device, which comprises a hinge mount, a first mandrel, a second mandrel, a permanent seat and a limiting seat symmetrically arranged at two sides of a stander, whereinthe upper end of the hinge mount is sleeved on the first mandrel and is movably connected with the upper end of the first mandrel through a fastening piece, and the lower end of the first mandrel isfixed on a movable component through the fastening piece; the upper end of the second mandrel is supported in the limiting seat, the middle part of the second mandrel supported in the permanent seat,a plurality of fastening pieces pass through the permanent seat and the second mandrel and are fixedly connected with a fixed component respectively; the lower end of the hinge mount is sleeved on thesecond mandrel and is movably connected with the second mandrel; and axial lines of the first mandrel and the second mandrel are vertical to each other. The hinge device solves the rotation without arotating shaft in a hinge rotating center, and simultaneously controls the inclined angle of a second rotating shaft to control the displacement of the rotating center of the hinge mount, changes thestress direction of a hinge, and improves the working strength of the hinge.

Description

technical field [0001] The invention relates to a movable connection device between two components, in particular to a connection device capable of opening and closing in space between two components, and belongs to the technical field of mechanical connection devices. Background technique [0002] Hinges are often used to connect movable and fixed components, such as doors and door frames, box covers and boxes. There are usually two types of conventional hinges. One is a hinge with only one revolving pair. The hinge is formed by the revolving pair of the mandrel and the sleeve. The center of rotation is determined, and the center of rotation is the center of the mandrel. Because there is a central mandrel in this hinge, the central mandrel occupies the spatial position at the corner of the movable member and the fixed member, so that this hinge cannot meet the opening and closing rotation of some special requirements, thus limiting its scope of use. . Another type of hing...

Problems solved by technology

Because there is a central mandrel in this hinge, the central mandrel occupies the spatial position at the corner of the movable member and the fixed member, so that this hinge cannot meet the opening and closing rotation of some special requirements, thus limiting its scope of use

Another type of hinge is a planar four-bar linkage hinge without a central mandrel. Through the movement of the four-bar linkage, the flip of the movable member can be realized. Although this kind of hinge can realize the rotation of the center of rotation without the central shaft, the displacement of the center of rotation It is too large to be used in components that require a relatively fixed center of rotation
