Referring to fig. 1-2, a fire monitor for fire-fighting and rescue and convenient for replacing a nozzle comprises a monitor base, a monitor body 3 and a nozzle 4, wherein the monitor base comprises a base 1 and a rotating frame 2, a water inlet end is connected to the base 1, the rotating frame 2 is arranged in a U-shaped structure, a connecting seat is installed at the top of the base 1 through a bolt, the rotating frame 2 is rotatably arranged on the connecting seat, and a water pipe (not shown in the figure) is connected between the monitor body 3 and the water inlet end;

the gun body 3 is rotatably arranged in the rotating frame 2 through a shaft connection, a mounting base 5 is screwed on one end of the gun body 3 through threads, a rocking handle is arranged on the other end of the gun body 3, a first fixing platform 51, a fixing shaft 52 and a second fixing platform 53 which are sequentially welded and fixed are arranged on one side of the mounting base 5, a movable platform 6 is arranged on the outer wall of the fixing shaft 52 in a sliding manner, the movable platform 6 is arranged to match with a bayonet 41 to carry out operations such as installation and replacement on the spray head 4, and a convex stud 54 is further arranged on the second fixing platform 53;

wherein, the first fixed platform 51, the fixed shaft 52 and the second fixed platform 53 are internally communicated and communicated with the gun body 3, so that the water flow is smooth;

the shower nozzle 4 is the setting of "T" type structure, and its inside has been offered and is a plurality of movable grooves of circumference distribution, and the activity inslot elasticity is provided with piston rod 42, and piston rod 42's setting has the drive guide effect to bayonet lock 41, and the one end of piston rod 42 exposes, and bonds on its other end and have bayonet lock 41, and the setting of bayonet lock 41 is for the installation change of convenient shower nozzle 4, and still offers the screw with double-screw bolt 54 adaptation in the shower nozzle 4.

In this embodiment, in order to limit the movement of the piston rod 42 and the detent 41, a limiting piece is bonded to the exposed end of the piston rod 42, a spring is sleeved outside the piston rod 42, one end of the spring is welded to the inner wall of the movable groove, and the other end of the spring is in contact with the detent 41.

Besides, it should be noted that the top and the bottom of the latch 41 are respectively provided with a first inclined plane and a second inclined plane, the first inclined plane is parallel to the lower surface of the movable table 6, and the second inclined plane is parallel to the upper surface of the movable table 6.

The working principle is as follows:

the firemen hold the rocking handle to rock back and forth, so that the gun body 3 can adjust the spraying angle and direction, and the fire can be extinguished in time;

when the nozzle 4 is replaced, the original nozzle 4 is rotated to one side of the second fixed table 53, the nozzle 4 is detached from the second fixed table 53 and then replaced with a new nozzle 4, the new nozzle 4 is rotated to one side of the first fixed table 51, and the operation is stopped until the bayonet lock 41 is clamped between the second fixed table 53 and the movable table 6, and the movable table 6 is also contacted with the first fixed table 51.

The specific process of replacing the spray head 4 is as follows:

referring to fig. 3, when the spray head 4 is installed, the spray head 4 is rotated downward in fig. 3, when the start is made, the bayonet 41 rotates downward against the surface of the second fixed table 53 and is gradually pushed into the movable groove by the surface of the second fixed table 53, when the bayonet 41 slides to the lower surface of the second fixed table 53, the bayonet 41 pops out along with the piston rod 42 under the action of the spring, after popping out, the limiting piece contacts with the outer surface of the spray head 4, the bayonet 41 is located between the second fixed table 53 and the movable table 6, the second inclined surface of the bayonet 41 contacts with the upper surface of the movable table 6, the plane on one side of the first inclined surface contacts with the lower surface of the second fixed table 53, and the lower surface of the movable table 6 at this time also contacts with the first fixed table 51, the upper end part of the stud 54 is screwed into the screw hole, and water flows into the front end of the spray head 4 from the screw hole after flowing out through the inside of the stud 54 and is sprayed out, and the spray head 4 does not contact with the installation seat 5 at this time;

referring to fig. 4, when the spray head 4 is removed, the spray head 4 is continuously rotated downward in fig. 3, so that the bayonet 41 slides against the upper surface of the movable table 6 (in the process, the bayonet 41 is pushed into the movable groove), and then continuously slides along the lower surface of the movable table 6 (in the process, the bayonet 41 is gradually popped out of the movable groove), when the spray head 4 contacts with the mounting seat 5, at this time, the stud 54 is completely matched with the screw hole, and the first inclined surface of the bayonet 41 contacts with the lower surface of the movable table 6, and then, the spray head 4 is rotated upward in fig. 4, so that when the spray head 4 is just rotated, the bayonet 41 synchronously drives the movable table 6 to move upward and to drive the movable table into the groove of the second fixed table 53, at this time, the spray head 4 is continuously rotated upward, the bayonet 41 starts to be pushed into the movable groove again, and after being separated from the lower surface of the movable table 6, the bayonet is popped out and moves along the upper surface of the second fixed table 53, and finally, the stud 54 is separated from the second fixed table 53, and the spray head 4 is in a natural state (when the movable table 6 is in a vertical state or a gun body 51);

in this process, it should be noted that a groove adapted to the movable table 6 is formed inside the bottom end of the second fixed table 53 (as shown in fig. 4).

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
