hinge device

Abstract

The invention belongs to the technical field of connecting pieces and particularly relates to a hinge device which comprises a first hinge bracket and a second hinge bracket, wherein a steering shaft and a support shaft are arranged in parallel at an interval on the upper side and the lower side of the second hinge bracket; U-shaped hinge arms are arranged on two sides of one end of the first hinge bracket; the heads of the hinge arms are hinged to the steering shaft; a sliding limiting plate is hinged to the support shaft; an L-shaped sliding hole is formed in the sliding limiting plate; a rolling shaft penetrating through the sliding hole is arranged between the tail parts of the two hinge arms. The hinge device has the following advantages: when the hinge device is used, the first hinge bracket rotates, the rolling shaft slides along the sliding hole in the sliding limiting plate, when the rolling shaft slides to the top of the sliding hole, the rolling shaft prevents the first hinge bracket from rotating, and when a hinge is required to be occluded, the first hinge bracket can automatically rotate for restoration through lightly poking the sliding limiting plate upwards, so that the problem that the traditional hinge cannot position after rotation during the using process is solved, and the product accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of connectors, in particular to a hinge device. Background technique [0002] A hinge is a mechanical device used to connect two solids and allow relative rotation between the two. It is generally installed on doors, windows, cabinets, and box covers. The structure adopted by the hinges in the existing market is that the hinge bracket rotates and opens during use. Afterwards, it cannot be automatically limited, and it cannot be limited according to the needs of users. The work efficiency of the hinge is low. Due to the structural defects of the traditional hinge itself, it is necessary to use a third-party structure to limit the hinge bracket during use. The structure of the hinge is more complicated. Contents of the invention [0003] The object of the present invention is to provide a hinge device that can automatically limit the position according to the user's needs and greatly improve the work effici...
