Wherein the fixed sleeve is welded with the box body. The part outside the box body is a switch spanner 1, and the part in the box body is a switch base 4.
At present, two fixing modes of a switch base in an explosion-proof box exist, and the first mode is to directly connect the switch base with a fixing sleeve 2 through a bolt 3, as shown in fig. 1.
This fixing method makes it difficult to have enough space to install and detach the switch base using a screw driver for the switch position to be close to the inside of the case or when the case is already filled with components, which brings great inconvenience to installation and maintenance.
The second is to fix the switch base 4 using an L-shaped bracket 5, as shown in fig. 2. Outside the box body, the switch base 4 and the L-shaped bracket 5 are fixed through the bolts 3, then the box body is placed in the box body, two fixing holes at the bottom of the bracket 5 are aligned with threaded holes of the flitch 6 welded with the box body, and the two are fastened and connected through the bolts.
Compared with the first mode of directly fixing by bolts, the fixing mode has the advantage that only 2 bolts are required to be screwed down, and therefore, the operation is less troublesome. But it also creates another problem. The L-shaped bracket and the L-shaped flitch 6 are formed by bending, so that the vertical precision of the L-shaped bracket and the L-shaped flitch is difficult to ensure, and in the continuous use process of the switch, the L-shaped bracket 5 is stressed unevenly and can generate certain deformation, so that the concentricity of the switch spanner and the switch base is changed, and the switch can be hard to be turned on again.
