Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain that this is practical
It is novel, it is not used to limit the utility model.
It in order to further illustrate the specific features of the utility model, is described in detail below with reference to relevant drawings, specifically
Referring to Figure 1 to Fig. 5.
A kind of electrokinetic cell system cabinet inner support beam component, the inner support beam component 1 include load bearing beam 1-1, mould group
