Specific embodiment:

Embodiment is shown in as shown in Figure 1 to Figure 3, a kind of spray gun of putting out a fire that glows of pressure adjustable, including spray head in a circular table shape 1, the inside of the spray head 1 forms the water storage cavity 101 of lower opening, and the upper side wall of spray head 1 forms the platform with water storage cavity 101 Rank through-hole 102 forms the small conical bore 103 of multiple outer imperial palaces, the inner end of conical bore 103 on the downside inner wall of water storage cavity 101 Pilot hole 104 is formed, the inside of the spray head 1 forms the intake chamber 105 of connection water storage cavity 101 and conical bore 103；

The upper end of the spray head 1 is equipped with nose cone 2, forms cylindrical projection 21, cylindrical projection on the bottom surface of nose cone 2 21 pass through bearing hinge connection in the upper end hole of step through-hole 102, and the lower stretching that cylindrical projection 21 passes through step through-hole 102 forms Screw rod 22 is bolted with lifting seat 3 on screw rod 22, multiple first hinged seats 31, the first hinged seat is formed on the outer wall of lifting seat 3 31 is hinged with the upper end of linking arm 4；A circular cone plug 5 is socketed in each conical bore 103, each circular cone plug 5 Inner end is fixed with a spring 6, and the inner end of every spring 6 is fixed with a guide post 7, and every 7 sleeve of guide post is corresponding In one pilot hole 104, the interior extension end that guide post 4 passes through pilot hole 104 forms the second hinged seat 71, and described second is hinged Seat 71 is hinged on the lower end of linking arm 4；

Connecting tube 8 is fixed on the bottom surface of the spray head 1, the lower end of connecting tube 8 is fixed on T-shape handle 9, described The water inlet duct 901 that connecting tube 8 communicates is formed on T-shape handle 9.

Further, the bottom surface 201 of the upper bottom surface 106 of the spray head 1 and nose cone 2 is rubbing surface, spray head 1 Upper bottom surface 106 is pressed against on the bottom surface 201 of nose cone 2.

Further, the upper side wall of the water storage cavity 101 forms heavy with the concentric setting of step through-hole 102 Hole is fixed with axle envelope 10 in counterbore, and the inner wall of axle envelope 10 is pressed against on the outer wall of cylindrical projection 21.

Further, the upper end of the connecting tube 8 forms terminal pad 81, and terminal pad 81 passes through bolt and spray head 1 Bottom surface be fixedly connected, annular groove is formed on the upper bottom surface of the terminal pad 81, O-ring 82 is socketed in annular groove, it is O-shaped The upper side wall of circle 82 is pressed against on the bottom surface of spray head 1.

Further, an Anti-slip cover 91 is respectively socketed on the both ends outer wall of the cross bar of the T-shape handle 9.

Working principle: first, the water inlet duct 901 of T-shape handle 9 is connect with extraneous water pipe, and extraneous water is through intaking Duct 901, connecting tube 8 enter in water storage cavity 101, and the water in water storage cavity 101 enters in conical bore 103 through intake chamber 105, Due to hydraulic pressure effect and overcome the pressure of spring 6, water ejects circular cone plug 5 outward, outer wall and circle of the water from circular cone plug 5 The internal spray of taper hole 103 and go out；Second, when needing to adjust the injection pressure of water outlet, pass through rotational circle conehead 2, nose cone 2 Screw rod 22 is driven to rotate by cylindrical projection 21, screw rod 22 drives lifting seat 3 to move up or move down, and lifting seat 3 moves up, and passes through connection Arm 4 pulls out guide post 7, and spring 6 increases the pulling force of circular cone plug, need bigger hydraulic pressure could to circular cone plug to Outer top, thus increase the injection pressure of water outlet, on the contrary lifting seat 3 moves down, and the injection pressure increase of water outlet is reduced；Third, it is real Spray head 1 and nose cone 2 need to be only inserted into combustible substance inside, can conveniently be inserted into combustible using nose cone by the used time Inside matter.

Finally, embodiment of above is merely to illustrate the utility model, and it is not limitation of the utility model, related skill The those of ordinary skill in art field can also make various changes in the case where not departing from the spirit and scope of the utility model Change and modification, therefore all equivalent technical solutions also belong to the scope of the utility model, the patent protection model of the utility model Enclosing should be defined by the claims.
