Description

Automatically actuated fire extinguisher

Technical field

The present invention relates to a kind of fire-extinguisher equipment as described in the preamble as claimed in claim 1.

Background technology

When breaking out of fire, out of hand for preventing the intensity of a fire, it is important getting started fire extinguishing.All there is fire extinguisher present most of family, workplace and public place.The shortcoming of these fire extinguishers is: their releasing device type difference, and need before discharging extinguishing chemical, read operation instruction, thereby cause the forfeiture of quality time.The strength that releasing device needs the user to have usually is that some people is inaccessiable.

The object of the invention is to avoid above-mentioned shortcoming, prevents that simultaneously fire extinguisher is stolen, and prevents to use back (after starting) to put back to its retainer at fire extinguisher.

The problems referred to above are known for a long time, but do not find the gratifying solution at these problems up to now.U.S. Pat 4482123 has been described a kind of device, is used to prevent that fire extinguisher from being hung back again after use, but does not have to solve the subject matter of existing fire extinguisher.U.S. Pat 5771997 is attempted the fire extinguisher of automatically starting when on fire, promptly starts the spring actuated device that can start extinguishing device by a kind of thermo-fuse and solves the problems referred to above.This device solves the relevant fire extinguisher problem that is difficult to start, but, therefore lost the advantage of extinguishing the fire location intensity of a fire because this device is pilotless, promptly Xian Chang user can not be with the physical location of extinguishing chemical jet aligning burning things which may cause a fire disaster.

Summary of the invention

The present invention addresses the above problem by a kind of equipment with characteristic as claimed in claim 1.The further beneficial characteristics of the present invention as can be seen from remaining appended claims.

In case take off fire extinguisher from the retainer of fire extinguisher, will start its releasing device, this will make that stealing fire extinguisher does not have attraction, because propellant will spray from fire extinguisher in several hrs, therefore do not have knowledge and the instrument that releasing device is not started, fire extinguisher is with useless.

Description of drawings

To and equipment of the present invention be described in further detail with reference to the accompanying drawings by specific embodiment below, wherein:

Fig. 4 b schematically shows the detail drawing of fire extinguisher tip part as shown in Figure 3; And

Fig. 5 represents to be used for the side view of retainer of the fire extinguisher of Fig. 3-4b.

The specific embodiment

Below with reference to Fig. 1,2 and 2a the possible embodiment of a kind of the present invention has been described.

The tip part 1 that is designed to satisfy requirement of the present invention is spun on the common vessel 6 of splendid attire extinguishing chemical.Tip part 1 can the mode identical with the tip part of the fire extinguisher of present commercialization design, it has a pressure gauge 7 that is used for monitoring the gas pressure of container, nozzle exit 8, with handle 4, but additional, in retainer shell 5, the relative both sides of the tip part among the present invention also have the groove 2 that matches with angular deflection device 3 to be used for hanging fire extinguisher or fixed fire extinguishing.Further, this tip part also have a startup piston 17 that matches with stop pin 11 ', this stop pin 11 passes the opening of fire extinguisher tip part 1 and will start piston 17 ' a be fixed on position that does not start.Since start piston 17 ' on loaded a spring 13 ', therefore in case remove stop pin 11, just force to start piston 17 ' downwards and press down shedding motion 30, thus this shedding motion open, make the extinguishing chemical air-flow flow into jet pipe 8 in known manner.Shedding motion presses down the opening/closing that is arranged in the container 6, and this is a standard for fire extinguisher, and can cause extinguishing chemical to flow in the jet pipe 8.

For fear of inferring the problem that how to start fire extinguisher, stop pin 11 is installed in the retainer shell 5, spurs handle 4 to take off fire extinguisher from shell 5 thereby work as the user, and stop pin 11 just remains in the shell 5, and has started fire extinguisher.Start fire extinguisher for fear of contacting with fire extinguisher unintentionally, handle 4 inserted in the groove 10 of bending of shells 5 both sides, thus will be from shell 5 draw-out handle, handle 4 must be changeed downwards.

Stop pin 11 can be known multiple mode be fixed on the shell, but the common ground of these fixed forms is that anyone has a responsibility for fire extinguisher is safeguarded etc. that this can take off fire extinguisher and not start this fire extinguisher with regard to needs from retainer shell 5.Wherein a kind of possible maintenance mode is fixed on stop pin 11 on the shell for using padlock 9, pin has a hole in the end at angle on the pin, the arcuate section of padlock 9 passes from this hole, referring to Fig. 2, deflection parts 12 that have a hole accordingly with described pin are fixed on the shell 5.

Second embodiment of invention is described below with reference to Fig. 3 and accompanying drawing afterwards.

Opposite with previously described embodiment, user oneself must have enough strength to start fire extinguisher, and just, release plunger 17 is non-spring-actuated, but can directly cooperate with handle 4.When pressing down handle 4, the release plunger 17 that the bottom has a bead 23 is pressed in the releasing device in the container 6.Making when spraying fire extinguisher, keep pressing down for fear of handle 4 always, described release plunger 17 has a notch 18, and this notch 18 flushes with passage 22 in the tip part when pressing down.With reference to figure 4b, described passage clamping one by the stop pin 19 of spring 20 bias voltages, one end of spring is near stop pin 19, the other end near by proper implements by the screw 21 of precession passage 22, perhaps this screw 21 is equipped with a locking device (in detail show), and this locking device need use a special key to screw and to unscrew the screw 21 in the tip part.Therefore, when pressing down release plunger 17, will force stop pin 19 to enter in the notch 18, and fire extinguisher is locked in enable position, fire extinguisher also remains on this position when handle 4 is released simultaneously.Can only use special tool(s) or special key by unscrewing screw 21 fire extinguisher not to be started, stop pin 19 is also along with spring 20 is thrown off together simultaneously.Spring 13 guarantees that handle 4 is parked in active position.

The retainer of this embodiment has been taked the form slightly different with previously described retainer, begins to start when retainer takes off with convenient fire extinguisher.Fig. 5 represents the side view by the retainer of being made up of lower member 28 and upper member 25, this lower member 28 and upper member 25 can by around axle 27 by handling so that fire extinguisher be installed on the retainer.Upper member 25 can be rotated down with lower member 28 near, and make it locked against lower member by locking 26.Arc handle 4 with a working face 29 from the side of shell stretch out and a L shaped groove 24 on the shell two sides be directed to, this working face 29 is near the upper end of release plunger 17.At non-actuation position,, make handle be positioned at the top of L shaped groove 24 because spring forces handle upwards.

When taking off fire extinguisher and starting, handle is pressed down, and when release plunger 17 was pressed down and is locked in enable position, fire extinguisher was removed, so the arcuate section of handle is located in the lower part of L shaped groove 24, and no longer is limited in the retainer

Identical in suspension in this embodiment container and the container of in first embodiment, describing.
