Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus protection domain of the present utility model is made apparent clearly
Define.
Referring to Fig. 1 and Fig. 2, this utility model embodiment includes:
A kind of automatic open close pressure release safety anti-explosive door, including: upper flange 2 and lower flange 1, described upper flange 2 and lower flange 1
Two ends be provided with magnet part for by upper lower flange adhesive, being provided with a center-pole 5 at the axle center of described upper flange 2,
Being connected by fixing nut 52 is fixing between described center-pole 5 and upper flange 2, the top of described center-pole 5 is provided with a disk
The top board 3 of shape, described center-pole 5 is flexibly connected between top board 3, is evenly arranged with three guiding in the outer end of described top board 3
Fix between post 4, and one end of three leads 4 with top board 3 and be connected, under the other end of lead 4 is fixed on through upper flange 2
At flange 1, being provided with guide holder 6 between described lead 4 and upper flange 2, the inner side of described guide holder 6 connects with lead 4
Contact portion is provided with ball 61, is additionally provided with spring 7 between the outside of described center-pole 5, top board 3 and upper flange 2.
Further, in order to improve the sealing between upper lower flange, also set between described upper flange 2 and lower flange 1
Being equipped with sealing, described sealing includes: sealing ring 8 and sealing gasket 9, and described sealing ring 8 is fixed on leading of upper flange 2 lower surface
Outside post, described sealing gasket 9 is arranged in the groove of lower flange 1 upper surface.Described sealing ring 8 is shaped to taper.
The upper surface of described sealing gasket 9 offers a cone tank 91, the shape of described cone tank 91 and the mating shapes of sealing ring 8.
