Background technology

A lot of fire are often all grown up by little flare, if put out in the stage of catching fire at the beginning, just can reduce a lot of losses.Though the fire extinguisher of small sized personal use now is very universal, possibility does not have with practice because of the user or learns, thereby can't in time in the fire initial period it be put out enlargement loss in use.

The fire extinguisher that generally uses now, as shown in Figure 1, fire extinguisher body 10 is provided with carrying handle 20 and spout 30; The valve 50 of mounting strap button 40 in the body 10; One end of pressure handle 60 and carrying handle 20 is articulated, and button 40 is replaced below pressure handle 60 by back-moving spring 70, and pressure handle 60 is respectively equipped with keyhole 80 with carrying handle 20 in the position near pivot end; Safety cock 90 passes keyhole 80 restriction pressure handles 60 and moves down, and guarantees that fire extinguisher is in closed condition at non-working condition lower valve 50.

During use, earlier safety cock 90 is transferred to from keyhole 80, made pressure handle 60 releases, to pushing pressure handle 60, the effect that the button 40 of drive valve 50 overcomes back-moving spring 70 is to descending again, and Open valve 50, extinguish material pass through spout 30 ejections, realize the fire-fighting fire extinguishing function.Stop to push pressure handle 60, the button 40 of valve 50 drives pressure handle 60 and resets thereupon at the effect of back-moving spring 70 horizontal reset that makes progress, and waits for that next fire-fighting fire extinguishing uses.

Anatomize said structure, be not difficult to find that there is following problem in it:

One, safety cock 90 is positioned at the side of pressure handle 60 and carrying handle 20, is not easy the person of being used and notes, if the user is unfamiliar with fire extinguisher; So when breaking out of fire; Might just note can it not being extracted, spray fire extinguisher thereby can't make less than the effect of perhaps unexpected safety cock 90;

Spray fire extinguisher even two users know how to make, but when fire took place, the people's was spiritual in tension following; Muscle is in automatic the tightening, and might cause following situation: the hand-tight pressure handle 60 of pressing, and the another hand removes to pull out safety cock 90; Perhaps because the resistance of 80 pairs of safety cocks 90 of keyhole; Form a radial effect power, and caused safety cock 90 to be difficult to extract, thereby incured loss through delay fire extinguishing opportunity;

Three, safety cock 90 is probably lost after use, makes pressure handle 60 keep releases and fire extinguisher is in stand-by state for a long time, maloperation very easily occurs; Poor stability; And can cause the wasting of resources to a certain extent, influence the recycling of fire extinguisher, even give for change; When reinstalling safety cock 90, also more loaded down with trivial details.

In order to address the above problem, the inventor has developed a kind of novel extinguisher valve pressure handle safety device through concentrating on studies.

As preferably, the operating side of shell fragment also is coated with flexible material.

After adopting such scheme, the present invention is used for fire extinguisher, under the untapped original state; The neck of operating side is arranged in narrower perforation and draw-in groove cooperates with narrower perforation peritreme; This moment pressure handle on locking bit, the valve pressure handle is in the security protection state, fire extinguisher can't use.During use, the operating side that only need touch shell fragment forward, after draw-in groove broke away from narrower perforation, the support that pressure handle loses draw-in groove can be pressed and move downward, and this moment, fire extinguisher can normally use.After finishing using, stir pressure handle, shell fragment blocks pressure handle once more, and the valve pressure handle is in the security protection state, thereby makes fire extinguisher be in stand-by state.

The present invention replaces safety cock because between carrying handle and pressure handle, increased the strip shell fragment, cooperates with notch cuttype perforation on the pressure handle by the draw-in groove of shell fragment neck, and the release of realization pressure handle and locking, so the present invention has following beneficial effect at least:

One, the operating side of shell fragment neck is positioned at the end face of pressure handle, is not used the person easily and notes, when breaking out of fire, can remove to stir shell fragment to subconsciousness, makes to spray fire extinguisher;

Two, stir the shell fragment ratio and take out that to dial the safety cock action simpler, laborsaving; Operation easily is when fire takes place, even the people's is spiritual in tension following; Muscle is in automatic the tightening; Still possibly easily accomplish release action, convenient in fire takes place by the back very first time, making sprays fire extinguisher, and fire extinguishing opportunity avoids delay;

Three, after use, only need stir pressure handle the neck operating side of shell fragment is come back in the narrower perforation, draw-in groove rebounds automatically, and shell fragment blocks pressure handle once more, and the valve pressure handle is in the security protection state, makes things convenient for the recycling of fire extinguisher.
