Embodiment
Below in conjunction with the accompanying drawings and specific embodiment is further elaborated to technical scheme.
Shown in Figure 1, a kind of inner cylinder of hand-held fire extinguisher, what the inner cylinder included setting along the vertical direction is stored with cold
But the upper cylinder 1 of agent 11, be stored with the lower cylinder 2 of Loading Materials for Initiating Explosive Devices 21, cylinder 1 is slideably set on the cylinder lateral wall of lower cylinder 2 on this,
Venting of dust explosion mouth 22 is offered in the cylinder side wall of the lower cylinder 2, being additionally provided with this on cylinder 1 can block on venting of dust explosion mouth 22 or away from the venting of dust explosion
The occlusion part of mouth 22.Inner cylinder also includes being set in guarantor on the lower end cylinder lateral wall of cylinder 1, can sliding with the slip of upper cylinder 1
Sheath 3, when occlusion part is away from venting of dust explosion mouth 22, the protective case 3 slides upwards with length direction of the upper cylinder 1 along lower cylinder 2, and the guarantor
The lower surface of sheath 3 is higher than the upper surface of venting of dust explosion mouth 22.
By opening up venting of dust explosion mouth 22 on lower cylinder 2 so that when the pressure in fire extinguisher inner cylinder exceedes setting value, occlusion part
Away from venting of dust explosion mouth 22 so that the partial gas pressure in inner cylinder is gone out from venting of dust explosion at venting of dust explosion mouth 22, is caused to prevent inner cylinder hypertonia quick-fried
Fried, detonation situation occurs, while venting of dust explosion mouth 22 is arranged on lower cylinder 2 so that in venting of dust explosion, the cooling agent 11 in upper cylinder 1
It will not be gone out from the venting of dust explosion of venting of dust explosion mouth 22；Simultaneously by setting protective case 3 in the cylinder side wall of upper cylinder 1 so that used in fire extinguisher
During, it can effectively prevent the situation that operating personnel burn when touching the cylinder side wall of inner cylinder accidentally from occurring.Herein, should
Protective case 3 is to be set in made of high-temperature-resnylont nylont material, and by the fixation of resistant to elevated temperatures glue in the cylinder side wall of upper cylinder 1.
In the present embodiment, cylinder 1 has inactive state and venting of dust explosion state on this.When upper cylinder 1 remains static, on this
Cylinder 1 is still set on the cylinder lateral wall of lower cylinder 2, and occlusion part is blocked on venting of dust explosion mouth 22；When upper cylinder 1 is in venting of dust explosion state
When, length direction upward sliding of the upper cylinder 1 along lower cylinder 2, away from venting of dust explosion mouth 22, the inner cylinder also includes being used to switch upper cylinder occlusion part
The controlling organization of 1 working condition.
In the present embodiment, the controlling organization includes being arranged on thin copper bolt between upper cylinder 1 and lower cylinder 2, and the two of the thin copper bolt
End can wear successively respectively by be fixed on after the cylinder side wall of lower cylinder 2, the cylinder side wall of upper cylinder 1 on the cylinder lateral wall of upper cylinder 1 or with
Upper cylinder 1, lower cylinder 2 are separated.At least one, thin copper bolt, for the ease of the installation of thin copper bolt, in the present embodiment, in lower cylinder
A pair of first mounting holes 24 are offered in the opposing sidewalls of 2 cylinder side wall, are offered and the first mounting hole in the cylinder side wall of upper cylinder 1
The second corresponding mounting hole of 24 positions, the both ends of thin copper bolt are worn by the first mounting hole 24, the second mounting hole successively respectively
It is fixed on afterwards on the cylinder lateral wall of cylinder 1.
When the pressure in inner cylinder is not up to setting value, thin copper bolt is fixed between cylinder 1 and lower cylinder 2, and upper cylinder 1 is in quiet
Only state, upper cylinder 1 are still set on lower cylinder 2；When the pressure in inner cylinder exceedes setting value, thin copper bolt bears incessantly inner cylinder
In air pressure and be broken, now, upper cylinder 1 is in venting of dust explosion state, and length direction of the upper cylinder 1 along lower cylinder 2 slides upwards, on upper cylinder 1
Occlusion part away from venting of dust explosion mouth 22 so that the partial gas pressure in inner cylinder overflows from venting of dust explosion mouth 22, subtract the pressure in inner cylinder
It is small, it effectively prevent the situation that blast detonation occurs because of hypertonia for inner cylinder.
In the present embodiment, the guide groove 23 for the sliding of upper cylinder 1 is further opened with the cylinder side wall of the lower cylinder 2.Referring to Fig. 1 institutes
Showing, the inner cylinder also includes that one end is fixedly connected with the upper phase of cylinder 1, the other end is slidably fastened on sliding part 4 in guide groove 23, this
Upper cylinder 1 is slidably set in by bearing of trend of the sliding part 4 along guide groove 23 on the cylinder lateral wall of lower cylinder 2.Herein, the cunning
Moving part 4 is stud 4, and the fixing hole being engaged with the screw thread of the stud 4 is further opened with the cylinder side wall of upper cylinder 1, the fixing hole
Open up position and the guide groove 23 in the cylinder side wall of lower cylinder 2 to open up position corresponding.Herein, the guide groove 23 has multiple,
All guide grooves 23 are evenly distributed in along same circumferencial direction in the cylinder side wall of lower cylinder 2.
In order to prevent fire extinguisher, in fire extinguishing, gas lets out between the gap of upper cylinder 1 and lower cylinder 2, and herein, this is interior
Cylinder is also included located at the seal 5 for being used for both sealings between upper cylinder 1 and lower cylinder 2.Shown in Figure 1, the seal 5 is to be arranged
Sealing ring 5 in lower 2 sidewall periphery portions of cylinder, the cylinder lateral wall phase sealed set of the madial wall of the sealing ring 5 and lower cylinder 2,
The medial wall of the tube phase sealed set of the lateral wall of the sealing ring 5 and upper cylinder 1.
