Brief description of the drawings
Fig. 1 is front view of the present utility model；
Fig. 2 is top view of the present utility model.
Embodiment
Technical solutions of the utility model are described in detail below, but protection domain of the present utility model is not limited to
The embodiment.
As depicted in figs. 1 and 2, a kind of buffering air lock device of the present utility model, including housing 1, turnover panel 2, rotating plate shaft 3, axle
Bearing 4 and weight 5, the upper opening inwall of housing 1 are fixed with bearing block 4, and housing 1 is Stainless Steel Shell, and thickness is 1.5~2mm,
Turnover panel 2 is two and is arranged on by what rotating plate shaft 3 rotated on bearing block 4, weight is also associated with rotating plate shaft 3, turnover panel 2 is in weight
Rotated in the presence of hammer and be abutted together the closing upper opening of housing 1, when two free ends of turnover panel 2 are abutted together, weight
Rotating plate shaft 3 is fixed on plane-parallel, weight includes support bar 7 and some variable weights 8, variable weights 8 are enclosed on support bar 7
On, horizontally disposed weight causes variable weights 8 to be difficult to come off from support bar 7, and particularly, the weight passes through with rotating plate shaft 3
Unilateral bearing connect, weight rotated centered on rotating plate shaft 3 it is to horizontal level unilateral bearing that its position is locked, when need change
During the variable weights 8 of weight, opposite direction rotate weight to upright position, be conveniently replaceable, and now the free end of turnover panel 2 but not by
Power, is conducive to improving the service life of turnover panel 2, and the upper opening of housing 1 is also associated with flange 5, the inclining with respect to the horizontal plane of housing 1
Rake angle is 80 °~90 °, while facilitating the material to fall, and is reduced between impact of the vertical drop to housing 1, two turnover panels 2
Angle is 110 °~130 °, and such angle design so that in the case that variable weights 8 are less, the turnover panel 2 being combined reaches most
Good sealing effectiveness, the upper surface of turnover panel 2 is provided with wear-resistant ceramic 6, and the thickness of wear-resistant ceramic 6 is 3~5mm, particularly, wear-resistant ceramic
