Detailed Description
The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 1 and 2, the utility model discloses preferred embodiment's circuit board special fixture for reinforcing display, including box casing 1, 1 one side opening of casing, four apron mounting holes 11 that are used for installing apron 2 on the 1 opening face of casing, two liang of settings of apron mounting hole 11 are on 1 width direction's of casing both sides. Four clamp mounting holes 12 are arranged on the outer side of the opening surface of the shell 1, and the clamp mounting holes 12 are arranged on two opposite sides of the shell 1 in pairs. The housing 1 is mounted at a desired position through the jig mounting hole 12.
As shown in fig. 2 and 3, a cover plate 2 for closing the housing 1 is provided on the opening of the housing 1, and a mounting block 21 engaged with the cover plate mounting hole 11 is provided on a surface of the cover plate 2 facing the inside of the housing 1. The cover plate 2 can be firmly mounted on the housing 1 to form a closed box body by screwing the mounting block 21 through the bolt assembly and the cover plate mounting hole 11.
As shown in fig. 2 and fig. 3, four circuit board mounting holes 4 are arranged on one surface of the housing 1 away from the opening, the four circuit board mounting holes 4 are distributed at four corners of one surface of the housing 1, mounting posts 41 extend from the circuit board mounting holes 4 to the inner side of the housing 1, and the circuit board 3 is mounted on the mounting posts 41 through bolt assemblies. The circuit board mounting holes 4 distributed at four corners of the shell 1 can better support the circuit board 3, and a gap can be left between the circuit board 3 and the inner side surface of the shell 1 through the mounting columns 41, so that the shell 1 is prevented from extruding the circuit board 3.
