141 tops are communicated with sliding slot 311, and sliding slot 311 is communicated with ventilation opening 13, and the first fixture block 151 is slidably connected in sliding slot 311,
First fixture block, 151 top cross-section is in sharp triangular shape.31 bottom of support frame offers card slot 312, and 312 section of card slot is in triangle
Shape, when 2 enclosed ventilation mouth 13 of hanging deck door, the first fixture block 151 is clamped with card slot 312.
Locking bar 15 is installed in cavity 141, locking bar 15 is elongated, and one end and 141 end of cavity are rotatablely connected, and first
Fixture block 151 is fixed on 15 top of locking bar.Torsional spring 153 is installed at locking bar 15 and 141 rotation of cavity, 153 two-arm of torsional spring is supported respectively
On 141 inner wall of locking bar 15 and cavity, the other end of locking bar 15 extends cavity 141 and is open outside, when filtration members 3 need to dismantle for touching
When, one end that locking bar 15 extends to outside cavity 141 need to only be pressed, the first fixture block 151 is with the rotation of locking bar 15 and and card slot at this time
312 separation, so that filtration members 3 are detached from.
Dashpot 16 is offered on door leaf 1, dashpot 16 is located at 13 lower section of ventilation opening, and slidably connects in dashpot 16
Buffer substrate tablet 162 is equipped with buffer spring 161 between buffer substrate tablet 162 and dashpot 16.161 one end of buffer spring and dashpot 16
Inner wall is fixed, and the other end and buffer substrate tablet 162 are fixed.It pushes buffer substrate tablet 162 to slide into dashpot 16 when hanging deck door 2 is closed, delays
It rushes spring 161 and buffer function is played to the rotation of hanging deck door 2, and after shock wave terminates, buffer substrate tablet 162 is assisted
Hanging deck door 2 is detached from ventilation opening 13, prevents hanging deck door 2 from influencing performance of ventilating because can not normally be detached from ventilation opening 13.
As shown in Fig. 2, being also equipped with limit assembly 4 below ventilation opening 13, limit assembly 4 includes position limit arm 41 and limit plate
42.41 one end of position limit arm and door leaf 1 are fixed, and limit plate 42 is tiltedly mounted on 41 other end of position limit arm so as to hanging deck door 2
Rotational angle is limited.
When the present embodiment is in use, when door leaf 1 is impacted, hanging deck door 2 turns to logical under the action of runner assembly
Until ventilation opening 13 is closed at air port 13, in 2 rotation process of hanging deck door, the sliding block 314 for being mounted on 31 bottom of support frame is being torn open
It is moved up under the conflict of 14 upper surface of piecemeal and the second fixture block 22 is pushed to be detached from card hole 313；When the completely enclosed ventilation of hanging deck door 2
When mouth 13, the second fixture block 22 is completely disengaged with card hole 313, at this time effect of the hanging deck door 2 in self gravity and buffer spring 161
Lower reset, flexible lock pin 21 can smoothly slide out lockhole 310；Meanwhile it is sliding on the card slot 312 of 31 bottom of support frame and fractionation block 14
The fixture block clamping for moving connection, realizes the fixation between filtration members 3 and ventilation opening 13, so that filtration members 3 and hanging deck door 2 are divided
From to realize the filtering function of filtration members 3, the dust for avoiding explosion from generating later pollutes air by ventilation opening 13.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
