Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is further elaborated technical scheme.
Shown in Figure 1, a kind of inner cylinder of fire extinguisher, the inner cylinder includes the upper cylinder 1 set along the vertical direction and lower cylinder 2,
Upper cylinder 1 is slideably set on the cylinder lateral wall of lower cylinder 2.Wherein, upper cylinder 1 is included arranged on upper 1 top of cylinder with spout 111
Nozzle cap 11, the cooling agent piece 14 in upper 1 inner cavity of cylinder, the upper net plate 13 on 14 upper surface of cooling agent piece and support
Elastic supporting member for supporting optical member 12 between upper 1 top of cylinder and upper net plate 13, lower cylinder 2 include be arranged on lower 2 inner cavity of cylinder in extinguishing medium column 21,
The venting of dust explosion mouth 22 being opened on a side wall, being additionally provided on the cylinder side wall of upper cylinder 1 can block on the venting of dust explosion mouth 22 or be let out away from this
The occlusion part of seam broken 22 is further opened with the vertically extending sliding slot 23 for the sliding of upper cylinder 1 on the cylinder side wall of lower cylinder 2, should
Inner cylinder further includes that one end is fixedly connected with upper 1 phase of cylinder, the other end is slideably opened in sliding part 3 in sliding slot 23, the cooling
Agent piece 14 is between upper net plate 13 and sliding part 3.By setting upper net plate 13, sliding part 3 and elastic supporting member for supporting optical member 12 so that this goes out
No matter in transportational process or during use, cooling agent piece 14 will not shake firearm, at the same by extinguishing medium with
Cooling agent is isolated so that will not react during the extinguishing medium that ignites, between extinguishing medium and cooling agent and
Influence the burning of extinguishing medium.
By opening up venting of dust explosion mouth 22 on the cylinder side wall of lower cylinder 2, it may be such that in fire extinguishing procedure cooling agent blocking such as occur
Spout 111, when causing inner cylinder hypertonia, upper cylinder 1 slides upwards along the length direction of lower cylinder 2, and occlusion part departs from venting of dust explosion mouth 22,
The venting of dust explosion from venting of dust explosion mouth 22 of the portion gas in inner cylinder is made to go out, so as to reduce the air pressure in inner cylinder, is effectively prevented interior
The explosion deflagration phenomenon that cylinder occurs due to hypertonia.Herein, which can have multiple, and all venting of dust explosion mouths 22 are along same
One circumferencial direction is equably opened on the cylinder side wall of lower cylinder 2.The set-up mode, has also effectively prevented during venting of dust explosion,
The cooling agent possibility that venting of dust explosion is gone out from venting of dust explosion mouth 22 in upper cylinder 1.
In order to further prevent cooling agent piece 14 because portion cooling agent is caused to drop from cooling agent piece 14 during collision, at this
In, cylinder 1 further includes lower net plate arranged on 14 lower end of cooling agent piece, being supported on 3 upper surface of sliding part on this（Do not show in figure
Go out）.
In the present embodiment, shown in Figure 1, which is stud 3, is further opened on the cylinder side wall of upper cylinder 1 with being somebody's turn to do
The matched mounting hole of screw thread of stud 3, corresponding, stud 3 that opens up position for opening up position and sliding slot 23 of the mounting hole
One end be mutually screwed with mounting hole be connected, the other end is slidably fastened in sliding slot 23.Herein, which has more
A, all sliding slots 23 are evenly spaced apart to be opened on the cylinder side wall of lower cylinder 2 along same circumferencial direction.
In the present embodiment, which is spring 12, shown in Figure 1, for the ease of the elastic supporting member for supporting optical member
12 installation, herein, the cylinder side wall top edge of upper cylinder 1 is inwardly curved to convex into the mounting portion installed for the elastic supporting member for supporting optical member 12
15, the one side edge of the mounting portion 15 is downwardly extending the feather edge of the nozzle cap 11.Elastic supporting member for supporting optical member 12 when mounted, only
It need to be fastened in mounting portion 15.Simultaneously because 111 bore of spout is smaller, in order to ensure cooling agent will not block up in ejection process
Spout 111 is filled in, herein, which is arranged in horn-like on the top of cylinder 1.
In the present embodiment, shown in Figure 1, cylinder 1 has stationary state and venting of dust explosion state on this, when upper cylinder 1 is in quiet
Only during state, cylinder 1 is still set on the cylinder lateral wall of lower cylinder 2 on this, and occlusion part is blocked on venting of dust explosion mouth 22；When upper cylinder 1
During positioned at venting of dust explosion state, upper cylinder 1 slides upwards along the length direction of lower cylinder 2, and the occlusion part on upper cylinder 1 is interior away from venting of dust explosion mouth 22
Partial gas pressure in cylinder is overflowed from venting of dust explosion mouth 22.The venting of dust explosion mouth 22 can be multiple, equably be opened up along same circumferencial direction
On the cylinder side wall of lower cylinder 2.
In the present embodiment, the inner cylinder further include it is between upper cylinder 1 and lower cylinder 2, for switching upper 1 working condition of cylinder
Control mechanism.The control mechanism includes the thin copper bolt of insurance being mounted between upper cylinder 1 and lower cylinder 2, the both ends of the thin copper bolt of the insurance
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 it is upper
Cylinder 1, lower cylinder 2 are separated.
At least one, the thin copper bolt of the insurance, for the ease of insuring the installation of thin copper bolt, in the present embodiment, in lower cylinder 2
A pair of first mounting hole 24 is offered in the opposing sidewalls of cylinder side wall, is offered and the first mounting hole 24 on the cylinder side wall of upper cylinder 1
Corresponding second mounting hole in position, the both ends for insuring thin copper bolt are worn successively respectively through the installation of the first mounting hole 24, second
It is fixed on behind hole on the cylinder lateral wall of cylinder 1.When the pressure in inner cylinder is not up to setting value, insures thin copper bolt and be regularly arranged on
Between upper cylinder 1 and lower cylinder 2, upper cylinder 1 remains static；When the pressure in inner cylinder is more than setting value, thin copper bolt fracture is insured, with
Upper cylinder 1, lower cylinder 2 are separated, and upper cylinder 1 is in venting of dust explosion state, and portion gas is overflowed from venting of dust explosion mouth 22, effectively prevent when cold
But the phenomenon that agent blocking spout, explosion detonation occurs due to cylinder pressure is excessively high for inner cylinder.
During the length direction of upper cylinder 1 along lower cylinder 2 slides in order to prevent, between cooling agent is between upper cylinder 1 and lower cylinder 2
It is overflowed at gap, in the present embodiment, sealing element 4 is additionally provided between upper cylinder 1 and lower cylinder 2, it is shown in Figure 1, herein, the sealing
Part 4 is the sealing ring 4 being set on the outside of lower 2 barrel of cylinder in circumference, and the inner ring of sealing ring 4 and the cylinder lateral wall of lower cylinder 2 mutually seal
It sets, outer ring and the medial wall of the tube phase sealed set of upper cylinder 11.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and implement according to this, and it is not intended to limit the scope of the present invention.It is all according to the present invention
The equivalent change or modification that Spirit Essence is made, should be covered by the protection scope of the present invention.
