Abstract
The utility model discloses a fire extinguisher. The fire extinguisher comprises a valve body, a barrel body, a sealing ring and a pressing screw cap, wherein a positioning shaft and an annular step are arranged at the bottom of the valve body; the sealing ring and the pressing screw cap sleeve the positioning shaft and the step, respectively; the top surface of the barrel body comprises a positioning hole; the positioning shaft is inserted in the positioning hole in a matched manner; the pressing screw cap is in threaded connection with the barrel body, and the upper end and the lower end of the sealing ring are in contact with the bottom surface of the valve body and the top surface of the barrel body, respectively. The fire extinguisher disclosed by the utility model avoids deflection of the spray angle of a valve body spray hole due to rotating and twisting of the valve body, is comfortable to use; moreover, the fire extinguisher is labor-saving in tightening.
Description
Technical field
The utility model belongs to a kind of fire-fighting equipment field, is specifically related to a kind of fire extinguisher.
Background technology
Traditional fire extinguisher includes valve body and cylindrical shell, and the bottom of described valve body is provided with external screw thread, and the top of described cylindrical shell is provided with internal thread, and both are tightened and be tightly connected by instrument.But when valve body is in the time tightening, valve body is very long, easily twisted partially, thereby the spray angle of valve body jet also easily falls partially, it is not comfortable especially using, and valve body is very heavy, so extremely require great effort in the time tightening.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is will solve valve body to be connected effort with cylindrical shell, and valve body is easily twisted inclined to one side problem.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of fire extinguisher, comprises valve body, cylindrical shell, sealing ring and clamping nut; The bottom of described valve body is provided with a locating shaft and annular step, described sealing ring and clamping nut are socketed in respectively on locating shaft and step, the end face of described cylindrical shell includes a locating hole, described locating shaft cooperation is plugged in locating hole, and described clamping nut is connected with cylinder screw and makes the two ends up and down of sealing ring contact respectively the bottom surface of valve body and the end face of cylindrical shell.
The material of described valve body is copper, and is provided with nickel coating.
The outer surface that described valve body includes a clamping nut be provided with at least one taking clamping nut as axle center the uniform convex tendon of annular.
The top of described valve body is provided with rotary sleeve and handle, and described rotary sleeve is connected with valve body, and described rotary sleeve and handle are hinged and handle is rotated up and down.
Described convex tendon has 8.
(3) beneficial effect
Fire extinguisher of the present utility model, the bottom of valve body is arranged to a step and locating hole, compress valve body and make valve body and cylindrical shell is tightly connected by clamp nut, comparing comparatively speaking traditional this this valve body of connected mode makes it to rotate without helicitic texture, when connection, rotate as long as control nut, therefore avoided partially falling because of the spray angle that the stubborn local derviation of valve body rotation causes valve body jet, thereby use more comfortable, and clamp nut is lightweight, volume is little, and it is more laborsaving, convenient to connect by spanner control clamp nut.
Brief description of the drawings
Fig. 1 is the structural representation of fire extinguisher of the present utility model; ;
Fig. 2 is the cutaway view of A-A in Fig. 1;
Fig. 3 is the enlarged drawing of B in Fig. 2;
In figure, 1 is that valve body, 2 is that cylindrical shell, 3 is that sealing ring, 4 is that nut, 5 is that locating shaft, 6 is that step, 7 is that locating hole, 8 is that convex tendon, 9 is that rotary sleeve, 10 is handle.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
A kind of fire extinguisher as shown in Figure 1-Figure 3, comprises valve body 1, cylindrical shell 2, sealing ring 3 and clamping nut 4, the bottom of described valve body 1 is provided with a locating shaft 5 and annular step 6, described sealing ring 3 and clamping nut 4 are socketed in respectively on locating shaft 5 and step 6, the end face of described cylindrical shell 2 includes a locating hole 7, described locating shaft 5 cooperations are plugged in locating hole 7, described clamping nut 4 is threaded with cylindrical shell 2 and makes the two ends up and down of sealing ring 3 contact respectively the bottom surface of valve body 1 and the end face of cylindrical shell 2, position that can fixed valve body 1 by this structure, as long as link by clamping nut 4 and cylindrical shell 2, make sealing ring 3 sealing rings contact to realize sealing with valve body 1 with cylindrical shell 2 respectively.Comparing comparatively speaking traditional this this valve body of connected mode makes it to rotate without helicitic texture, when connection, rotate as long as control nut 4, therefore avoided partially falling because of the spray angle that the stubborn local derviation of valve body rotation causes valve body jet, thereby use more comfortable, and clamp nut is lightweight, volume is little, and it is more laborsaving, convenient to connect by spanner control clamp nut 4.
The material of described valve body 1 is copper, and is provided with nickel coating, and this structure can make valve body 1 structure more firm.
The outer surface that described valve body includes a clamping nut 4 be provided with 8 taking clamping nut 4 as axle center the uniform convex tendon 8 of annular, can be blocked by spanner by this structure, thereby clamping nut 4 is realized and unscrewed and tighten.
The top of described valve body 1 is provided with rotary sleeve 9 and handle 10, described rotary sleeve 9 is connected with valve body 1, described rotary sleeve 9 is hinged and handle 10 is rotated up and down with handle 10, when handle 10 rotates when downward, the entirety that reduces fire extinguisher takes up room, conveniently deposit and transport, when handle 10 rotates upwards certainly, fire extinguisher can normally use.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
