Hidden bracket

Abstract

The invention discloses a hidden bracket, which comprises an underframe, wherein the underframe is assembled with guide rails fixedly arranged on a cabinet body in a sliding way to realize the extension and hiding of the bracket; a support is hinged to the underframe, is retracted when the bracket is hidden, is expanded when the bracket extends, and comprises support rods extending along straight lines. The hidden bracket is characterized in that the support also comprises underframe connecting rods, wherein one end of each underframe connecting rod is integrated or fixedly connected with the corresponding support rod, and the other end of each underframe connecting rod is correspondingly hinged to the underframe; hinging central axes on hinged parts, correspondingly hinged to the underframe, on the support rods and the underframe connecting rods are eccentric; the underframe, the underframe connecting rods and the support rods form a connecting rod mechanism capable of retracting the support rods to positions at which the extension directions of the support rods are parallel to the sliding direction of the underframe when the support is retracted. According to the bracket, the support rods can be retracted to the positions at which the extension directions of the support rods are parallel to the sliding direction of the underframe, so that the space occupied by the support is maximally reduced, and the requirement of the bracket on the space of the cabinet body is lowered.

Description

technical field [0001] The invention relates to a hidden bracket. Background technique [0002] At present, when installing a heavy switch mechanism on the switch cabinet or performing on-site maintenance, it is often necessary to use a transfer vehicle, which provides a transfer platform for easy access to the switch mechanism. However, the transfer vehicle occupies a large area and has high requirements for the site area. In places with limited area, the number of transfer vehicles is limited, which will affect the efficiency of maintenance of the switch mechanism. [0003] In the Chinese utility model patent specification whose authorized announcement number is CN2290935Y, a draw-out folding bracket that can be applied to the switch cabinet body is disclosed. The folding bracket includes a guide rail for sliding assembly with the cabinet body to realize The bottom frame with the bracket protruding and hidden, the bottom frame is hinged with a bracket for retracting the ...

Problems solved by technology

[0005] The purpose of the present invention is to provide a hidden bracket to solve the problem that the support rods extending in a straight line on the support in the prior art are directly hinged to the bottom frame, so that the support rods cannot be recovered to a position parallel to the sliding direction of the bottom frame. technical problem
