In addition, the plurality of blades 300 are in a fully closed state when positioned horizontally, and are fully open when the blades are rotated by 90 degrees in a vertical state, and the plurality of blades 300 are simultaneously rotated. Operated, but the blades 300 abutting each other are rotated in the opposite direction, if the odd numbered blade is rotated to the right, the even numbered blade is rotated to the left,

The odd-numbered shafts 200 are coupled to and rotated by one link on the outer side of the housing, and the even-numbered shafts are coupled to the other link on the other side of the housing. And rotated.

In addition, the configuration of the blade 300 is odd, even in two cases, the left blade 310 is composed of the left blade upper surface 311 and the left blade lower surface 312, the left blade upper surface ( The end of 311 is bent upward to form the upper left bent portion 313 of the left blade, and the right blade 320 is made up of the upper right blade 321 and the lower right blade 322 of the blade corresponding thereto. An end of the right blade lower surface portion 322 is bent downward to form a bent portion 323 when the right blade is lower.

The present invention is described in detail by the accompanying drawings as follows. 1 is a front view when two shafts and two blades are installed in the blade damper of the present invention, FIG. 2 is a front view when two shafts and two blades are installed in the blade damper of the present invention, FIG. Front view when two blades are installed, Figure 4 is a detailed view of the blade damper of the present invention.

Blade damper of the present invention is installed in a frame, a parallel state spaced apart from each other in the interior of the frame, a plurality of shafts for opening and closing the inner space of the frame, and a blade coupled to penetrate the shaft.

In addition, the frame is formed in a rectangular frame shape penetrating the upper, lower, a plurality of shafts are arranged in a line inside the frame of the frame, the blade is coupled to the shaft having a rectangular cross-section horizontal, the shaft When rotated, the blades rotate together to open and close the inner space of the frame.

As shown in detail in FIG. 4, the plurality of blades are in a fully closed state when positioned horizontally, and are fully opened when the blades are rotated 90 degrees in a vertical position. When positioned horizontally, the open side of the frame is completely closed.

In addition, the plurality of blades are rotated at the same time, but the blades in contact with each other is rotated in the opposite direction, if the odd numbered blades are rotated to the right, the even numbered blades are rotated to the left.

Therefore, the odd numbered shafts are coupled to one main link at the outer side of the housing and rotated, and the even numbered shafts are coupled to the other main link at the other outer side of the housing. Is rotated.

One end of the shaft is coupled to the auxiliary link, respectively, the end of the auxiliary link is coupled to the main link, the shaft is rotated as the main link is linear reciprocating motion by the hydraulic cylinder.

That is, one main link is installed on the opposite side of the frame, and the plurality of blades are rotated at once by the reciprocating motion of the pair of main links.

And the configuration of the blade is odd, even in two cases, the left blade is composed of the left blade upper surface and the left blade lower surface portion, the end of the left blade upper surface is bent upward to form a left blade upper surface bent portion. Correspondingly, the right blade is composed of an upper right blade and a lower blade of the right blade, and an end of the lower blade of the right blade is bent downward to form a bent portion of the lower blade.

On the other hand, in the present invention, when the product thickness is 2mm, the distance 'A' from the left shaft to the bending point of the upper surface of the left blade is 0.3mm from the right shaft to the distance (B) from the right side of the upper blade to the end of the right blade. The distance (C) from the shaft to the tip of the left blade top surface is the distance (B) from the right shaft to the tip of the top blade of the right blade. It is fixed at 60 degrees.

The angle E formed by the upper left blade upper bent portion and the upper right blade upper blade portion is 70 degrees or more to prevent interference during rotation.

The length of the left blade lower bend portion G is set to 15% of the length of the left blade lower blade portion D, and the length of the right blade lower blade is also set to 15% of the length of the lower blade lower blade.
