Two ends of the supporting bar 2 are respectively connected with two opposite side walls of the pressure relief hole B. The side of the support bar 2 facing the air intake end is formed with an installation groove. The mounting grooves of the supporting bars 2 of the rear row far away from the air inlet end in the multiple rows of supporting bars 2 are aligned in a one-to-one correspondence with the side far away from the air inlet end of the flow guiding gap 20 between the supporting bars 2 of the front row near the air inlet end in the multiple rows of supporting bars 2. The width of the mounting groove of the support bar 2 at the rear row is larger than the width of the guide gap 20.
In the present embodiment, the front and rear rows of support bars are spatially offset. The position of the supporting bars in the rear row corresponds to the flow guiding gap between the supporting bars in the front row.
A plurality of lead bars 3 are respectively installed in the installation grooves of the plurality of rows of supporting bars 2. And a lead bar is arranged in the mounting groove of each supporting bar.
According to the pressure relief hole dislocation protection device, the front row of supporting strips and the rear row of supporting strips are arranged in a dislocation mode, radiation can be effectively blocked, the protection efficiency is over 95%, the double effects of pressure relief and protection are achieved, the lead strips are arranged in the protection barrel through the supporting strips, the impression quality of the protection device is greatly improved, and the protection device is not prone to deformation caused by collision.
