A new design initiation device is that the connecting powder part of a lead wire is paper twisted; the lead part is made of plastics; the casing tube of the lead wire is divided into a connecting casing and a storage casing; the sealing cap of the new design initiation device adopts a double-layer structure plastics which are transparent and inflammable; the connection of a plug with the connecting casing and the connection of the sealing cap with the storage casing are tightly coupled. The portable initiation device for dried powder extinguisher has the advantages of reliable structure, wetting resistance, good manufacturability, quite initiation speed and low failure fire, and is an ideal initiation device.

Description

Portable initiation device for dried powder extinguisher

The utility model relates to the extinguishing device technical field.

Existing portable dry powder extinguisher initiating device, 87211118 Chinese patent application for example, its initiating device adopts dry clay to tighten sealing between plug and the flexible plastic sleeve; Fuse only adopts the spill fuse; Adopt the adhesive tape sealing at the fuse place of lifting one's head, the sticking again one deck in adhesive tape outside is brushed the cardboard of damp-proof paint outward.This initiating device shortcoming is may be because of stressed and loosening in when carrying, and spill fuse easy fracture so just can't ignite and forms " miso-fire "; The mode that fuse adopts the spill fuse directly to draw, not only moisture-sensitive fracture, and tensile strength is low, does not just fill out slightly and breaks, and giving ignites causes difficulty; The lead-out wire place of lifting one's head adopts adhesive tape to seal that then the poor reliability manufacturability is also poor.

The purpose of this utility model is that initiating device is structurally made improvements, and overcomes above-mentioned shortcoming.

The purpose of this utility model is achieved in that new design initiating device is made up of gas generator body, powder column, fuse, plug, fuse sleeve pipe and seal, and its feature is being: the fuse sleeve pipe is divided into adapter sleeve and stores cover; Lead-out wire is divided into two parts of spill and plastics; Be connected to tight fit between plug and the adapter sleeve; Gas hair generator body and plug are thread connection; Seal is the double walled sealing cap that transparent, inflammable plastics are made.From powder column, lead to bifilar low twist fuse, be split into the long and short two thigh lifting one's head punishment, short one drawn into fast knot and kept here, another thigh then passes plug bottom aperture Φ a, and give the space stayed and the plastics line end of igniting at plug and adapter sleeve, beat binode and advance to draw connection, this plastics fuse other end then passes adapter sleeve aperture Φ a and passes and store cover aperture Φ a, gives staying part to draw into the coil spring shape to exist and store in the cover space.Sealing cap is friction tight hermetically-sealed construction with storing cover.Exist in the storage cover space because the plastics fuse is drawn into the coil spring shape, as long as with the sealing cap breakdown, the plastics fuse just can eject the end of a thread automatically by the elastic force of itself, has won the time for putting out a fire as early as possible.

Be described further below in conjunction with drawings and Examples.

Fig. 1 is the utility model structural representation.

Mark among the figure: 1. sealing cap, 2. the plastics fuse is 3. stored cover, 4. adapter sleeve, 5. plug, 6. spill fuse, 7. powder column, 8. gas generator body.

Fig. 2 is gas generator structure of tube body figure.

Fig. 3 is the plug structural map.

Fig. 4 is the adapter sleeve structural map.

Fig. 5 is for storing the cover structural map.

Fig. 6 is the sealing cap structural map.

The gas generator body is a cylindrical shape as shown in Figure 2, is made of plastics, the external spreading nozzle that contracts in being furnished with on every side, and the upper end has the external screw thread M on internal thread and the plug (5) to spin.Plug (5) is by injection molding as shown in Figure 3, external diameter Φ d has the concentric holes of Φ a, Φ b, three sections different-diameters of Φ c along central axis, following sector hole Φ a is used for wearing spill fuse (6), middle sector hole Φ b is used for the space that spill fuse (6) is connected with plastics fuse (2), and last sector hole Φ c is used to assemble adapter sleeve (4).As shown in Figure 4, adapter sleeve (4) is by plastic injection-moulded material moulding, and external diameter is Φ c, also has the hole of corresponding Φ a, Φ b and Φ c along central axis, Φ b hole promptly is used for the space that spill fuse (6) is connected with plastics fuse (2), and Φ c external diameter is used for assembling and stores cover (3).Store cover (3) as shown in Figure 5, the lower end external diameter is Φ e, and the upper end external diameter is Φ f, and the stage casing external diameter is Φ b; Have the hole that two sections diameters are Φ a, Φ b along central axis.Φ a hole is used to wear plastics fuse (2), and Φ b hole is used to store plastics fuse (2) and fitting tight cap (1).Sealing cap (1) structure is illustrated in figure 6 as double walled, is made by inflammable transparent plastic, and its external diameter is Φ k, and internal diameter is Φ g, constitutes annular groove by diameter of phi i, Φ j; Constitute the taper seat of being convenient to assemble by diameter of phi h and Φ i.Powder column (7), interior dress Sefety powder, the spill fuse is bifilar to be distributed in the middle of the Sefety powder, and the lower end kills, and the spill fuse of certain-length is stretched out so that be connected with the upper plastic fuse in the upper end.Storing cover is made of plastics.

The utility model initiating device gives placing easy breaking out of fire place earlier at dry powder extinguisher, when the condition of a disaster took place, naked light or high temperature made inflammable plastic closure cap fusing, and responsive plastics fuse is lighted and to spill fuse and the detonation of powder column initiation gunpowder.When dry powder extinguisher is planned directly to come into operation, sealing cap to be opened, the plastics fuse just ejects automatically, directly lights with naked light, and velocity of initiation can be rapider.

The utility model compared with the prior art, is made with easy to assembly, and steady quality is reliable, and humidity resistance is good, and tensile strength is big, and velocity of initiation is fast, and the misfire rate is low, is a kind of more satisfactory initiating device.
