The guide rail passes through the sliding slot being fixedly connected on air door pressure relief window two sides.Guide pipe or cunning are provided on the inside of pressure relief window
Slot slides the arc iron plate (item) for connecting reverse side knob in guide pipe or sliding slot.
The guide rail is arcuate structure, the rotation center of guide rail and hinge center overlapping of axles, fixed between the end of guide rail
It is connected with knob two.Wind deflector front and back sides, which need to be provided with, facilitates staff that (pushing away) is drawn to play wind deflector knob, to guarantee to keep out the wind
Plate is in the position that is relatively fixed of pressure relief window.
Thickness >=3mm of the wind deflector, material are steel plate.
It is described to be fixedly connected as welding connection structure.
The beneficial effects of the utility model are: compared with prior art, using the technical solution of the utility model, this release
Relief damper solves that mine is mainly big into, air return system connection roadway both ends pressure difference, and staff is haled and (pushed away) during air door
Safety problem.By air door release, a people can easily open wind by connection roadway, so as to avoid several personal resultant forces or make
With crowbar using the security risk during lever principle drawing (pushing away) air door, the safety coefficient during switch air door is increased,
It also avoids and damages air door during drawing (pushing away) air door using crowbar, substantially increase the safety operation system of pressure relief safety air door
Number, extends the service life of pressure relief safety air door, substantially reduces the time that worker opens air door, has ensured the peace of worker
Entirely, good using effect is achieved.
