Below, investigate the effect that produces with process and structure of wearing of air respiratorresuscitator of the present utility model with said structure.
Confirm at first whether positive voltage regulator 9 usefulness open and close valves 15 and bypass valve 14 close, under the state of bearing the shoulder back 3 that air vessel 1 is installed, connect face shield coupling 6 then, finish being connected of face shield 10 and air vessel 10.
Then, the atmosphere breathing equipment 16 that is installed on face shield 10 is set in " atmosphere breathing " state, put on face shield 10 in face, worn after the face shield 10, the container value 4 that is arranged on air vessel 1 inlet is all opened, and confirm to be positioned at the user right side pressure gauge 20 pointer whether 290 to 300kgf/cm
2(28.4 to 29.4Mpa) scope.
Then open and be used to open and close positive voltage regulator 9 open and close valves 15 that are installed on face shield 10, simultaneously atmosphere breathing equipment 16 is set in " positive pressure respiration " state, then the pressure-air of sending from air vessel 1 carries out the 1st decompression by high pressure regulator 5, becomes about 8kgf/cm
2After, carry out the 2nd decompression by positive voltage regulator 9, become the normal pressure that is suitable for operator's breathing, be sent to face shield 10 at last.
When carrying out above-mentioned action, by the air of supply certain pressure in being arranged at the switch portion 22 that connects on the flexible pipe 7, above-mentioned switch 22 is opened, and the opening operation by above-mentioned switch, apply signal, thereby be arranged on flicker portion 23 operation of glimmering automatically of shoulder 3 left and right sides, back.
Devote on-the-spot operator with above-mentioned state, operate to the position at other clear and definite its places of operator,, take some countermeasures rapidly so can find seeking help person's request of seeking help and wearer's security incident as early as possible by the flicker of flicker portion 23.
Below, investigation relates to the cargo handling process of the positive voltage regulator 9 of Fig. 3 of the present utility model and Fig. 4.
The connecting portion 9a that inserts positive voltage regulator 9 in the joint portion 10a of face shield 10 front portions that the user wore carries out combination, therefore, at first at connecting portion 9a branch paired thread connection tool 17a, 17b is set and forms complete cylindric.
At this moment, forming right thread connection tool 17a, 17b is respectively equipped with support slot 18a and supports teat 18b on the corresponding position that is in contact with one another, make them be positioned at mutual tram so carry out contraposition, and, can keep bonding state by at through hole 19 binder bolt 19a and nut 19b.
Under above-mentioned state, if the threaded portion (not shown) that will be in the 10a of the joint portion of face shield 10 all sides form is meshing to the threaded portion that forms at thread connection tool 17a, 17b outer peripheral face, then shown in the sectional view of Fig. 4, joint portion 10a becomes the shape that supports thread connection tool 17a, 17b, simultaneously by meshing thread connection tool 17a, 17b being fixed in the fixedly raised line 9b that is arranged on connecting portion 9a front end, prevent its disengaging, thereby can make positive voltage regulator 9 become bonding state with face shield 10.
On the other hand, when wanting from face shield 10 separation malleation adjusters 9, if to direction rotation thread connection tool 17a, 17b in contrast to above-mentioned action, the screw thread binding site between the joint portion 10 of then positive voltage regulator 9 and face shield 10 is separated.
Thus, above-mentioned combined structure of the present utility model is, than in the past structure decrease the number of spare parts that is used to link, become easy and simple so shirk operation, thereby have advantage favourable aspect action effect.
Below, investigation relates to the action effect of the airtight band of Fig. 5 to Fig. 7 of the present utility model.
At first, be provided with and airtightly be with 30 carrying out position that crimping links, the operator temporarily is linked to stator 31 Fig. 7 a position of fixing hole 37 with hand then.At this moment, by the ends 35 of leading along guide part 34 guiding, the both side ends of airtight band becomes unanimity, can become stable binding.
Under temporary transient connecting state loosely, use the sharp keen instrument of front end, in the 2nd handle hole 36 that exposes by slotted hole 32 and the 1st handle hole 33, insert instrument respectively, push airtight band then, direction to fastening belt applies pulling force simultaneously, slough the stator 31 that temporarily is linked to fixing hole 37 positions, then it is linked on the b position, and be with 30 to add certain tension force airtight.
By said method,, finish airtight combination by the 10b of face being close to the 10c of respirator portion.
By the of the present utility model airtight band of aforesaid operations process combination, because have one-piece type binding structure,, improved productivity ratio, and combined closely, thereby had the advantage that improves operability by simple and easy operation so reduce the part number.
In addition, because not to the outstanding part in outside, so attractive in appearance and prevent the danger of injured skin.
On the other hand, illustrate that according to Fig. 8 and Fig. 9 the atmosphere of positive voltage regulator 9 breathes or be used for selecting the piston 44 and the associated methods between the guide rod 48 of compositing factor of atmosphere breathing equipment 16 of positive pressure respiration as follows.The 3rd section 48c of portion with guide rod 48, insert the internal diameter that leads to the 44c of section portion in the cylindrical portion 44a that is arranged at piston 44, the end face central part of the 3rd of mark guide rod 48 the section 48c of portion then, involutory instrument pressurization labeling section, then the diameter of the 3rd section 48c of portion becomes big, its result, guide rod can be the center rotation and not come off that work is combined into one with the piston section 44c of portion.During above-mentioned pressurized operation, can use suitable grip device, operate with similar approach.
Cover serum cap 42 in the conical surface of above-mentioned piston 44 and the convex-concave portion with diameter more many greatly than the external diameter of piston 44, the certain diameter recess that is arranged on serum cap 42 central parts is fitted at the outstanding cylindrical portion 44a that becomes convex of the central part of piston 44, and chimeric serum cap 42 is when being close to steam vent in the above-mentioned valve body 40 by the elastic force of spring 45, be fitted to the convex-concave portion of above-mentioned serum cap 44 and flexibly crooked by serum cap 42 parts that contact with steam vent one end of valve body, increase sealing area, simultaneously by the airtight function of 2 heavy airtight raisings.
As mentioned above, air respiratorresuscitator of the present utility model is, the compressed air in the air vessel stably can be supplied in face shield, and because can improve the productivity ratio of manufacture course of products and the security in the salvage work, so, can give the consumer high reliability.
In addition, by internal structure is oversimplified more, can obtain easier product mix and decomposition.
