Abstract
The utility model relates to an injection type fire extinguisher which is used for firing an injection bomb to generate high pressure gas required by an injection extinguishing agent. The utility model is formed by assembling an extinguishing agent cylinder with an injection device. The injection device is composed of an injection pipe, a sear, a firing pin, a connecting casing, a casing pipe, and a protection cylinder. The injection bomb is filled in the injection pipe. The high pressure gas caused by firing the jetting bomb is ejected from the jet nozzle. Extinguishing agents in the extinguishing agent cylinder can be ejected into fire points to extinguish fire. The injection device after using can be provided with a bomb again. A fire extinguisher is formed by assembling the injection device with a new extinguishing agent cylinder.
Description
The utility model relates to a kind of injecting type fire extinguisher that Jetting type bomb for fire extinguishing produces gases at high pressure of pulling the trigger, and is made up of extinguishing chemical tube and injection apparatus.
Known injecting type fire extinguisher is " a kind of impulse jet fire extinguisher " (application number is 99218257.3) and the disclosed injecting type fire extinguisher of " assembly type ejecting fire extinguisher " (application number is 00222553.0).These two kinds of injecting type fire extinguishers all are to produce the required gases at high pressure of spray fire extinguishing agent with the percussion Jetting type bomb for fire extinguishing.Weak point is that the injection apparatus structure is complicated.
The purpose of this utility model is to provide a kind of structure of injection apparatus simpler, the injecting type fire extinguisher that cost is cheaper.
The purpose of this utility model realizes by following scheme:
Injecting type fire extinguisher of the present utility model is made up of extinguishing chemical tube and injection apparatus.The extinguishing chemical tube is to fill the individual components that is prefabricated into behind the extinguishing chemical in the storage tube.Injection apparatus by playpipe, sear, firing pin, connect cover, sleeve pipe and casing and form.Playpipe is installed in and connects the cover front end, sear is installed in the sear chute that connects cover, and firing pin is installed in the hit pinhole that connects the cover rear end, and the cover that connects that playpipe, sear, firing pin have been installed is fixedly mounted in the sleeve pipe, and casing is by being slidingly installed in the sleeve pipe rear end.The draw-in groove that sear has shape hole, garden and is communicated with shape hole, garden.There is rotatable snap ring the firing pin rear end, and the casing rear end has the annular groove that snap ring can pass through.The Jetting type bomb for fire extinguishing that produces gases at high pressure is seated in the playpipe.
The utility model is compared with known injecting type fire extinguisher, and it is simple in structure to have an injection apparatus, advantage of low manufacturing cost.
In the accompanying drawing: figure one is an internal structure profile of the present utility model, and figure two is sear structural representations, and figure three is snap ring view when being stuck in the casing rear end.Figure one is book extract accompanying drawing as an illustration also.
Below in conjunction with description of drawings embodiment of the present utility model.
Injection apparatus of the present utility model and prefabricated extinguishing chemical tube connect into the injecting type fire extinguisher.The extinguishing chemical tube is to fill extinguishing chemical (2) to make in storage tube (3), and extinguishing chemical tube front end has protecgulum (1).When Jetting type bomb for fire extinguishing (6) was pulled the trigger, gases at high pressure were from the storage tube (3) of jet (4) the spirt extinguishing chemical tube of injection apparatus, and had been with extinguishing chemical (2) to wash protecgulum (1) open to be ejected into ignition point.Injection apparatus by playpipe (5), sear (10), firing pin (11), connect cover (8), sleeve pipe (7) and casing (13) and form.Playpipe (5) connects cover (8) front end with being threaded in, and Jetting type bomb for fire extinguishing (6) is seated in the cartridge chamber of playpipe (5), and the front end of playpipe (5) has jet (4).Firing pin (11) is the garden cylindricality firing pin of many steps, firing pin (11) stage casing external diameter maximum, so that striker spring (12) can be installed in the rear end, front end can stick into the draw-in groove on the sear (10).Sear (10) is processed into " L " shape, has the hole, garden that can pass through in firing pin (11) stage casing and the draw-in groove that can block firing pin (11) front end on the long limit.The long limit of sear (10) is installed in the sear chute that connects cover (8), and the minor face of sear (10) is compressed in sear spring (9) in the sear spring hole that connects on the cover (8).Firing pin (11) is installed in the hit pinhole that connects cover (8) rear end after passing the shape hole, garden that is installed on the long limit of the sear (10) that connects in cover (8) the sear chute.Striker spring (12) is contained in firing pin (11) rear end.The cover (8) that connects that playpipe (5), sear (10), firing pin (11) and striker spring (12) have been installed is fixedly mounted in the sleeve pipe (7) with attachment screw (15), and firing pin (11) rear end passes from the hole of sleeve pipe (7) rear end.Casing (13) is by being slidingly installed at sleeve pipe (7) rear portion.There is rotatable snap ring (14) firing pin (11) rear end, and casing (13) rear end has the annular groove that snap ring (14) can pass through.During snap ring (14) whiz annular groove, snap ring (14) is stuck on the casing (13), and pulling back casing (13) can pull back firing pin (11).When snap ring (14) was aimed at annular groove, firing pin can travel forward.When needing to use, casing (13) is spurred to the injection apparatus rear end, the snap ring (14) that is stuck in casing (13) rear end drives firing pin (11) compression striker spring (12) and moves back to the injection apparatus rear end, after firing pin (11) stage casing enlarged diameter section is deviate from from the hole, garden of sear (10), sear (10) upwards takeoffs under the effect of sear spring (9), the draw-in groove of sear (10) blocks firing pin (11) front end, and is in arm-to-arm.When needing to spray, after rotary clip (14) makes snap ring (14) aim at the annular groove of casing (13) rear end, pressing sear (10) frees firing pin (11) from the draw-in groove of sear (10), firing pin (11) travels forward under the effect of striker spring (12), and firing pin (11) bump Jetting type bomb for fire extinguishing (6) makes Jetting type bomb for fire extinguishing (6) percussion promptly realize spraying.
