Abstract

The invention discloses a fixing frame capable of facilitating maintenance of a circuit board. The fixing frame comprises a rectangular base, wherein a first portal bracket and a second portal bracketare arranged at two sides of the upper surface of the rectangular base separately; fixed bearings are arranged on the upper surfaces of the first portal bracket and the second portal bracket; a horizontal rotating shaft is arranged in each fixed bearing; a rectangular fixing frame fixedly connected with the horizontal rotating shafts is arranged between the first portal bracket and the second portal bracket; a threaded through hole is processed in the upper surface of the rectangular fixing frame; a threaded rod is embedded into the threaded through hole; and a rotating bearing sleeves one end, at the inner side of the rectangular fixing frame, of the threaded rod. The fixing frame has the beneficial effects that the circuit board is fixed by adopting a method of extruding and fixing theside of the circuit board, so that the damage of a fixing clamp to the surface of the circuit board is avoided; and the fixing angle of the circuit board can be adjusted and the circuit board can be turned over at any time, so that maintenance of the circuit board is facilitated.

Description

technical field

[0001] The invention relates to the field of circuit board fixing, in particular to a fixing frame for convenient circuit board maintenance. Background technique

[0002] The names of the circuit boards are: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin Thin circuit boards, printed (copper etching technology) circuit boards, etc. The circuit board makes the circuit miniaturized and intuitive, and plays an important role in mass production of fixed circuits and optimizing the layout of electrical appliances. During the use of the circuit board, various failures may occur, which need to be repaired in time. In order to facilitate the maintenance of the circuit board, it is necessary to reasonably fix the circuit board, so a bracket or a platform for fixing the circuit...
