Operation principle of the present utility model is: conventional fire extinguisher is provided with a lock, before opening fire extinguisher, need to extract lock to remove the locking of opening device, but, there is dangerous situation in emergency circumstances, particularly in the dark, among people's confusion, be difficult to find lock and extract lock, people in the moment of desperation are often because of life instinct, use and go to make to spray fire extinguisher compared with great strength, and this fire extinguisher is for these actual conditions, be provided with holddown spring one and holddown spring two, in the time slightly pressing down valve rod, can not open the opening of holding vessel, but need to be compared with great strength, press down valve rod and make valve rod push plunger open, just can open fire extinguisher, can either guarantee that fire extinguisher can not opened by people's maloperation, and guarantee that people can open fast fire extinguisher among the moment of desperation, do not delay fire extinguishing opportunity, better embody the effect of fire extinguisher.
In above-mentioned a kind of fire extinguisher, the upper end of described fire extinguisher body is hinged with a pressing plate, and the upper end of described pressing plate and described valve rod leans.Press down pressing plate, pressing plate extruding valve rod is moved down, thereby open fire extinguisher.
In above-mentioned a kind of fire extinguisher, in described tank body, be provided with a baffle plate, described baffle plate is provided with through hole, and described holddown spring two is arranged between plunger and baffle plate.Baffle plate is for support compression spring two, and through hole on baffle plate can guarantee that the firing-fighting medium in holding vessel can enter into outside holding vessel smoothly.
In above-mentioned a kind of fire extinguisher, between described holding vessel and described fire extinguisher body, there is a separate cavities.In the holding vessel of fire extinguisher, be generally the medium after compression, for holding vessel protection being arranged to this separate cavities.
In above-mentioned a kind of fire extinguisher, between described valve rod and fire extinguisher body, seal by sealing ring.
Compared with prior art, the utlity model has following advantage:
1, in the time slightly pressing down valve rod, can not open the opening of holding vessel, but need to be compared with great strength, press down valve rod and make valve rod push plunger open, just can open fire extinguisher, can guarantee that fire extinguisher can not opened by people's maloperation.
2, this fire extinguisher has guaranteed that people can open fast fire extinguisher among the moment of desperation, does not delay fire extinguishing opportunity, better embodies the effect of fire extinguisher.
