The utility model relates to a spray nozzle of a fire extinguisher. The utility model is provided for providing a fire extinguishing device part which is suitable for different fire extinguishing agent, evenly sprays, prevents turbulent flow and has good fire extinguishing effect. The utility model comprises a fixed seat and a rod body, wherein the front end of the fixed seat is in a hollow horn shape which forms an inner bevel, and internal threads are arranged on the inner edge of the back end of the fixed seat; the rod body is in a hollow shape which forms a channel; a plurality of spray orifices are arranged around the peripheral surface of the front end of the rod body side by side, and a plurality of radial grooves which are respectively corresponding to the spray orifices and communicated with the spray orifices are arranged on the inner edge of the front end; the rod body is orderly provided with first external threads and second external threads from the front end to back; the rod body is fixedly locked on the internal threads on the back end of the fixed seat by the first external threads, and the front end of the rod body is exposed out of an opening at the front of the fixed seat.
Description
Technical field
The utility model belongs to the extinguishing device parts, particularly a kind of fire extinguisher shower nozzle.
Background technology
As shown in Figure 1, the top of existing fire extinguisher 1a is provided with shower nozzle 11a.During use, the pressure handle 13a by squeeze grip 12a top makes the extinguishing chemical of internal memory outwards be sprayed by shower nozzle 11a.The shower nozzle 11a of existing fire extinguisher 1a is hollow form, is provided with so as to being locked on the external screw thread 111a on the fire extinguisher 1a in shower nozzle 11a end.The shower nozzle 11a of this kind structure is applicable to foam, powder extinguishing agent, but can't use for liquid extinguisher, and the shower nozzle 11a of this kind structure easily produces turbulent flow because of only being provided with single squit hole when spraying, and causes fire extinguishing poor effect, undesirable.
Summary of the invention
The purpose of this utility model provides a kind of fire extinguisher shower nozzle that is applicable to various extinguishing chemicals, sprays evenly, prevents turbulent flow, good extinguishing effect.
The utility model comprises the holder and the body of rod; It is horn-like that the holder front end is the hollow that forms interior inclined-plane, and inner edge is provided with internal thread in the holder rear end; The body of rod is the hollow form that forms passage, and the lever front end outer peripheral face is around being provided with several spray orifices side by side, and is provided with several radial grooves corresponding respectively and that be communicated with several spray orifices in the front end inner edge, and the body of rod is provided with first external screw thread and second external screw thread backward in regular turn by front end; The body of rod is locked on the internal thread of holder rear end with first external screw thread, and makes lever front end by holder front openings emergence.
Wherein:
Be provided with the portion of screwing between first and second external screw thread.
Because the utility model comprises the holder and the body of rod; It is horn-like that the holder front end is the hollow that forms interior inclined-plane, and inner edge is provided with internal thread in the holder rear end; The body of rod is the hollow form that forms passage, and the lever front end outer peripheral face is around being provided with several spray orifices side by side, and is provided with several radial grooves corresponding respectively and that be communicated with several spray orifices in the front end inner edge, and the body of rod is provided with first external screw thread and second external screw thread backward in regular turn by front end; The body of rod is locked on the internal thread of holder rear end with first external screw thread, and makes lever front end by holder front openings emergence.During assembling, be locked on the fire extinguisher, during use, outwards spray by several spray orifices of front end again after the extinguishing chemical in the fire extinguisher is entered by the passage rear end of the body of rod with second external screw thread on the body of rod.Because spray orifice is around shape and is arranged side by side, and be provided with groove corresponding with spray orifice and that be communicated with in the front end inner edge, therefore extinguishing chemical is able to outwards be spilt by the interior inclined-plane that groove relends in horizontal direction by the holder front end, and being fan-shaped range sprays, thereby can not form turbulent flow and spray more even, improve the fire extinguishing effect, and by the guide functions of spray orifice 31 and groove 32, so be applicable to foam, dry powder and liquid extinguishing chemical.Be not only applicable to various extinguishing chemicals, and spray evenly, prevent turbulent flow, good extinguishing effect, thereby reach the purpose of this utility model.

The specific embodiment
As Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the utility model fire extinguisher shower nozzle 100 comprises the holder 2 and the body of rod 3.
It is horn-like that holder 2 front ends are the hollow that forms interior inclined-plane, is provided with internal thread 21 in holder 2 rear end inner edges.
The body of rod 3 is the hollow form that forms passage, the body of rod 3 front end outer peripheral faces are around being provided with several spray orifices 31 side by side, and being provided with several radial grooves 32 respectively corresponding and that is communicated with several spray orifices 31 in the front end inner edge, the body of rod 3 is provided with correspondence and first external screw thread 33 that locks with holder 2 rear end internal threads 21 backward in regular turn, screws portion 34 and is arranged at second external screw thread 35 of the portion of screwing 34 rear ends by the front end that is provided with several spray orifices 31.
By above-mentioned member, the body of rod 3 is locked on the holder 2 rear end internal threads 21 with first external screw thread 33, and makes the body of rod 3 front ends by holder 3 front openings emergences.
During assembling, as shown in Figure 6, be locked on the fire extinguisher 1, so that the extinguishing chemical 4 of fire extinguisher 1 inside is able to outwards spray via the body of rod 3, and is even output and can not produce turbulent flow, to improve the fire extinguishing effect with second external screw thread 35 on the body of rod 3.
As shown in Figure 7, during use, after being entered by the passage rear end of the body of rod 3, outwards sprays by several spray orifices 31 of front end again the extinguishing chemical 4 in the fire extinguisher 1.Because spray orifice 31 is around shape and is arranged side by side, and be provided with groove 32 corresponding with spray orifice 31 and that be communicated with in the front end inner edge, therefore extinguishing chemical 4 is able to outwards be spilt by the interior inclined-plane that groove 32 relends in horizontal direction by holder 2 front ends, and being fan-shaped range sprays, thereby can not form turbulent flow and spray more even, improve the fire extinguishing effect, and by the guide functions of spray orifice 31 and groove 32, so be applicable to foam, dry powder and liquid extinguishing chemical.
In sum, the utility model cooperates to be provided with around several spray orifices 31 that are arranged side by side and the body of rod of groove 32 to be the trumpet-shaped holder 2 of hollow, makes fire extinguisher 1 be applicable to different extinguishing chemicals, and be even sprinkling when using, to improve the fire extinguishing effect.
