Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Example 1:

the carbon brush box described in this embodiment, as shown in fig. 1 to 3, includes a box body 1, the box body 1 includes a top plate 2 and a first cavity wall 3 and a second cavity wall 4 symmetrically disposed on the top plate 2, a spring hook 5 for fixing a torsion spring is disposed on the top plate 2, symmetrical notches 7 are disposed on the first cavity wall 3 and the second cavity wall 4, a first bottom plate 31 is further disposed on the first cavity wall 3, a second bottom plate 41 is further disposed on the second cavity wall 4, the first bottom plate 31 and the second bottom plate 41 are spliced with each other, a first fixing hole 32 and a first clamping device 30 for fixing the second cavity wall 4 are disposed on the first bottom plate 31, and a second fixing hole 42 and a second clamping device 40 for fixing the first cavity wall 3 are disposed on the second bottom plate 41.

In this embodiment, the first clamping device 30 on the first bottom plate 31 will clamp the second cavity wall 4, the second clamping device 40 on the second bottom plate 41 will clamp the first cavity wall 3, and the first bottom plate 31 and the second bottom plate 41 are engaged with each other in a snap-fit manner. The first chamber wall 3, the second chamber wall 4, the first bottom plate 31, the second bottom plate 41 and the top plate 2 can form a space which is stable, reliable and convenient for carbon brush movement.
