Further, cellular casing is divided into multiple grid by diaphragm plate and midfeather, and each grid is built with viscous Stagnant liquid.
Further, cellular welding box body is on connection end plate.
Further, multiple damper bars are respectively welded on the cover board, are wherein welded with ribbed stiffener between each two damper bar.
Further, the quantity of damper bar with equipped with viscous liquid grid quantity it is identical, the position of damper bar be equipped with The position of the grid of viscous liquid is corresponding.
Compared with prior art, the application can be obtained including following technique effect:
The damping force adjustable type viscous damping case that the utility model is provided, using damper bar generation resistance is moved in viscous liquid Buddhist nun's power, viscous liquid product, the height of damper bar and section form, the grid number of cellular casing etc. can affect damping force Size, therefore, the size of damping force can be just adjusted by above-mentioned parameter, the damping force adjustable function of viscous damping case is capable of achieving, More accurately damping power consumption is provided for structure.Meanwhile, damper bar can produce damping force in any direction motion in viscous liquid, Realize being acted in multi-direction viscous power consumption.The design of damping force adjustable type viscous damping case is convenient, easy to install and replacing, in the structure Can flexible arrangement, with good economy and practicality, application prospect is extensive.
Certainly, implementing arbitrary product of the application must be not necessarily required to while reaching all the above technique effect.
