Description
Technical field
The utility model relates to fire extinguisher technical field, especially a kind of 360 degree of rotatable spray tools.
Background technique
Connection type used by spray on the market has at present is to be threadedly coupled, and structure is complicated, and dismounting is inconvenient.Sebific duct two
End is designed using split type collet, is designed using endless groove, after such structure is withheld, clamping force is less than normal, and jet pipe is total
It is easy to fly out with sebific duct at collet after pressure-bearing and cause casualties.Jet pipe assembly both ends do not carry out conducting design, can imitate because of electrostatic
It answers and phenomenon of getting an electric shock occurs.Therefore current spray lamps structure has not been suitable for present fire extinguisher spray tool.
Utility model content
A kind of 360 degree of rotatable spray tools are provided purpose of the utility model is to solve the deficiency of above-mentioned technology,
It is limited using circlip, is able to achieve spray canister and carries out 360 degree rotation.
In order to achieve the above object, 360 degree of one kind rotatable spray tools designed by the utility model, including spray canister, nozzle
With jet pipe assembly, the jet pipe assembly includes sebific duct and the collet that sebific duct both ends are arranged in, and the collet is hollow tube-shape knot
Structure, is recessed annular cavity in the axial direction on the annular sidewall of collet one end, and the sebific duct includes outer glue-line and inner glue layer,
Steel wire is set between outer glue-line and inner glue layer, and the steel wire of sebific duct both ends end is exposed to outside, the both ends difference of sebific duct
It is arranged in inside the annular cavity of collet, internal screw thread, institute is provided on the jackets inner wall of the one end for being not provided with annular cavity
Stating nozzle is hollow tubular structure, and the outer wall in nozzle one end is provided with external screw thread, passes through between nozzle and one of collet
It is threadedly coupled, position is provided with annular protrusion among the outer surface of nozzle, and the spray canister includes ontology and is arranged in ontology
The connecting tube of one end forms a step in the junction of ontology and connecting tube, and the diameter at the step is greater than annular on nozzle
The diameter of protrusion, the diameter of connecting tube is less than the diameter of annular protrusion on nozzle, in the ontology of the spray canister close to connecting tube one end
Two sides are provided with two jump-ring slots, are provided with circlip in jump-ring slot, jump-ring slot at step at a distance from be greater than annular on nozzle
The width of protrusion, and the spacing between two jump-ring slots is less than the diameter of annular protrusion on nozzle.
Above-mentioned technical proposal is integrated design using collet, and inside forms gas port, and is arranged on side wall at one end
Sebific duct end steel wire expose portion is arranged inside collet annular groove, and is riveted tightly by withholding, and realizes collet and sebific duct
Connection it is stronger, the safety in use process is higher, while being threadedly coupled between nozzle and collet, connection fastening；And
The annular protrusion on nozzle is limited in by inside by step and circlip between nozzle and spray canister, to realize that spray canister can be 360 degree
It is freely rotated.When dismounting and change jet pipe need to be carried out, it is only necessary to extract circlip, jet pipe can be extracted, and back out nozzle.Separately
Outside, between two collets by steel wire conducting be a conductor, avoid personnel when putting out a fire because CO2 injection caused by electrostatic due to send out
Raw electric shock phenomenon.
As optimization, helicla flute is provided in the internal side wall of the annular cavity of collet.The design of the structure passes through folder
The tightening force of the design of helicla flute on the inner wall of the annular groove of set, sebific duct and collet is bigger.The limit that the present invention passes through circlip
Type of attachment, spray canister can rotate 360 °, to improve the assembly efficiency of spray tool, while jet pipe assembly is repairing more
Dismounting is more convenient when changing.
A kind of obtained 360 degree of rotatable sprays tool of the utility model, by the limit type of attachment of circlip, spray canister can be with
Rotate 360 °, thus improve spray tool assembly efficiency, while jet pipe assembly dismounted when repairing replacement it is more convenient；Separately
The outer exposed steel wire in sebific duct both ends avoids situations such as getting an electric shock so that both ends are connected.
