In figure：Graphite felt 1 is (wherein：Erecting bed 1.1), liquid flow frame 2 (wherein：Installing port 2.1).
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
A kind of mounting structure for being easy to assemble graphite felt in all-vanadium flow battery as shown in Figure 1, including graphite felt 1 and liquid
Flow frame 2, it is characterised in that：The graphite felt 1 is provided with the erecting bed 1.1 being easily installed, and the vertical section of the erecting bed 1.1 is
Square, trapezoidal or arc.The erecting bed 1.1 has two, and described two erecting beds 1.1 are symmetricly set in graphite felt 1.It is described
Liquid flow frame 2 is provided with the installing port 2.1 used cooperatively with erecting bed 1.1.The installing port 2.1 also has two, described two peaces
Dress mouth 2.1 is symmetricly set on inner side frame of the liquid flow frame 2 without flow passage side.The height of the erecting bed 1.1 and installing port 2.1
Depth is identical.
In the present embodiment：The height of the erecting bed 1.1 and the ratio of the thickness of graphite felt 1 are 0.6, the installing port 2.1
The ratio of depth and the thickness of liquid flow frame 2 is 0.8.
When the utility model is specifically used：
Embodiment 1：
