Abstract
The utility model discloses a kind of fire extinguisher pressure limit instruction device, including inflator, the indicating bar being mounted in inflator is mounted in inflator and with the piston of cylinder inner wall cooperation, the cover being connect with inflator, and the resetting apparatus for making indicating bar reset；Inflator one end is threadedly coupled integrally formed with circular ring cover, the other end with cover；Cylinder inner wall is fixedly connected with the erecting bed of annular close to a side of circular ring cover；Indicating bar one end can be in annulus cap bore inner shaft to movement, and the other end is fixedly connected with the piston；Indicating bar is yellow portion, green portion and red portion outward from inner end.Air pressure in fire extinguisher and spring（Or pressure membrane）Under the action of, indicating bar is released inflator, pressure is bigger, the distance that indicating bar stretching is gone is also bigger, and indicating bar is outward yellow portion, green portion and red portion from inner end, thus plays the role of indicating fire extinguisher pressure condition, it is simpler than traditional pressure gauge for fire extinguisher structure, and it is more intuitive, it can be with multiple directions, far from away from observation.
Description
Technical field
The utility model belongs to pressure gauge for fire extinguisher field, and in particular to a kind of fire extinguisher pressure limit instruction device.
Background technology
Since present fire extinguisher air gauge surface is at vertical plane, so that be put on the ground and chest in go out
Firearm inspection is got up to bother very much, will squat down, or even also fire extinguisher is taken out in chest, rotate, ability
See barometric instruction situation.It is very laborious in this way to take.
Invention content
Technical problem to be solved in the utility model is：In view of the deficienciess of the prior art, the utility model designs
A kind of instruction device for conveniently knowing fire extinguisher pressure limit.
To realize the purpose of the utility model, it is achieved using following technical scheme：
A kind of fire extinguisher pressure limit instruction device, includes inflator, and the indicating bar being mounted in inflator is mounted on inflator
Piston that is interior and coordinating with cylinder inner wall, the cover being connect with inflator, and make the resetting apparatus of indicating bar reset；The inflator
One end is threadedly coupled integrally formed with circular ring cover, the other end with cover；The cylinder inner wall is fixed close to a side of circular ring cover to be connected
It is connected to the erecting bed of annular；Described indicating bar one end can be in annulus cap bore inner shaft to movement, and the other end is fixedly connected with the piston；
The indicating bar is yellow portion, green portion and red portion outward from inner end；The resetting apparatus is connect with erecting bed.
Indicating bar yellow portion, green portion and red portion are painting layer, and indicating bar outer end face is coated with red paint painting
Layer.
The resetting apparatus is pressure membrane, and pressure membrane is fixedly connected with erecting bed.
The resetting apparatus may be spring, and the spring one end is fixedly connected with erecting bed, and the other end is solid with piston
Fixed connection.
Compared with prior art, the utility model has the beneficial effects that：Air pressure in fire extinguisher and spring（Or pressure
Film）Under the action of, indicating bar is released inflator, pressure is bigger, and it is also bigger that indicating bar stretches out the distance gone, indicating bar from inner end to
It is outside yellow portion, green portion and red portion, thus plays the role of indicating fire extinguisher pressure condition, than traditional fire extinguisher
Pressure meter structure is simpler, and more intuitive, can be with multiple directions, far from away from observation.

With red portion 23；The resetting apparatus is connect with erecting bed.The cover forms connecting tube 31, for being connect with fire extinguisher.
Indicating bar yellow portion, green portion and red portion are painting layer, and indicating bar outer end face is coated with red paint painting
Layer.
The resetting apparatus is pressure membrane 5, and pressure membrane 5 is fixedly connected with erecting bed.
Embodiment 2
A kind of fire extinguisher pressure limit instruction device, includes inflator, and the indicating bar being mounted in inflator is mounted on inflator
Piston that is interior and coordinating with cylinder inner wall, the cover being connect with inflator, and make the resetting apparatus of indicating bar reset；The inflator
One end is threadedly coupled integrally formed with circular ring cover, the other end with cover；The cylinder inner wall is fixed close to a side of circular ring cover to be connected
It is connected to the erecting bed of annular；Described indicating bar one end can be in annulus cap bore inner shaft to movement, and the other end is fixedly connected with the piston；
The indicating bar is yellow portion, green portion and red portion outward from inner end；The resetting apparatus is connect with erecting bed.The cover
Connecting tube is formed, for being connect with fire extinguisher.
Indicating bar yellow portion, green portion and red portion are painting layer, and indicating bar outer end face is coated with red paint painting
Layer.
The resetting apparatus may be spring, and the spring one end is fixedly connected with erecting bed, and the other end is solid with piston
