Abstract
The utility model discloses a wind tunnel for wind fire-extinguishers, which comprises at least two wind tunnel units and a connection unit arranged therebetween. The connection unit may be a connecting sleeve with mutually-engaged threads or a stretchable conical surface. With the arrangement, the size of wind tunnel is reduced greatly and correspondingly the size of packaging box is also reduced, facilitating the package and transportation and facilitating the carrying by firemen on the fire scene when the wind fire-extinguisher is not in use.
Description
Technical field
The utility model relates to a kind of wind fire-extinguisher, more particularly, relates to a kind of air duct of wind fire-extinguisher.
Background technology
Wind fire-extinguisher air duct of the prior art constitutes by an air duct.This kind structure since volume big, can't change, when packing, require the volume of packing case also bigger thereupon, bring very big inconvenience to transportation; Simultaneously, when fire-extinguishing location was stopped machine, the team member of also being inconvenient to put out a fire carried.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of wind fire-extinguisher air duct that carry packed and transported and working site of being convenient to is provided.
In order to solve the problem of above-mentioned existence, the utility model adopts following technical proposals: a kind of wind fire-extinguisher air duct, comprise air duct, and described air duct is made up of at least two air ducts, is provided with jockey between air duct and the air duct.
This jockey can be big adapter sleeve and the little adapter sleeve that is provided with the screw thread that cooperatively interacts, and described big adapter sleeve is separately fixed on two air ducts that need to be connected with little adapter sleeve.
For fixed, this kind is fixing can to adopt riveted way.
This jockey can also be provided in a side of the taper seat on interconnective two air ducts.
Owing to adopt technique scheme, the wind fire-extinguisher air duct that the utility model provides has such beneficial effect: be easy to carry and transport, because air duct can be dismantled or flexible, volume can dwindle, the volume of corresponding packing case also reduces, and is simple in structure, easy to operate.
Description of drawings
Fig. 1 is the assembling schematic diagram of first kind of embodiment of the utility model;
Fig. 2 is the cutaway view of first kind of embodiment;
Fig. 3 is the assembling schematic diagram of second kind of embodiment of the utility model;
Fig. 4 is the cutaway view of second kind of embodiment.
Among the figure: 1. Fan casing, 2. big air duct, 3. little air duct, 4. big adapter sleeve, 5. little adapter sleeve, 6. rivet, 7. rivet, 8. internal thread, 9. external screw thread, 10. big taper seat, the 11. roundlet conical surfaces.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing and specific embodiment:
Among Fig. 1, big air duct 2 is connected with Fan casing 1 usefulness bolting, and little air duct 3 is fixedlyed connected with big air duct 2.
In Fig. 2, big three rivets 6 of adapter sleeve 4 usefulness are riveted on an end of big air duct 2, are provided with internal thread 8 on big adapter sleeve 4; Simultaneously, three rivets 7 of little adapter sleeve 5 usefulness are riveted on little air duct 3 and the end that big air duct 2 is connected, and are provided with the external screw thread 9 that matches with internal thread 8 on little adapter sleeve 5.Cooperation by internal and external screw thread couples together air duct.During spray work, little air duct 3 by being threaded on the big air duct 2, when stopping machine, can be unloaded down little air duct 3.
Fig. 3 is the assembling schematic diagram of second kind of air duct, and big air duct 2 is bolted to connection with Fan casing 1, and little air duct 3 is connected with big air duct 2 by the conical surface.
In Fig. 4, an end of big air duct 2 is provided with big taper seat 10, and an end that is connected with big air duct 2 at little air duct 3 is provided with the roundlet conical surface 11 that matches with big taper seat 10.By the cooperation between taper seat, form telescopic air duct.During spray work, little air duct 3 is extracted out from big air duct 2,, made little air duct 3 can not get back in the big air duct 2 by the high wind that engine blows out.When stopping machine, littler air duct 3 is pushed in the big air duct 2, the team member of being convenient to put out a fire carries at fire-extinguishing location.
Air duct connection of the present utility model is not limited only to above-mentioned situation, and in first kind of embodiment, big adapter sleeve 4, little adapter sleeve 5 also can be fixedly connected on big air duct 2 and the little air duct 3 by alternate manners such as bolt or welding.
