[0026] The following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] In the present invention, unless otherwise stated, the orientation terms such as "up, down, left, right, inside, outside" included in the terms only represent the orientation of the terms in the normal use state, or the common names understood by those skilled in the art, and should not be regarded as a limitation to the terms.

[0028] See Figures 1 to 3 , the present invention provides a fire hose nozzle base, which includes a support assembly located at the bottom and a four - axis rotating body 2 provided on the support assembly and capable of rotating up, down, left, and right. One or more female connectors 1 for connecting the hose nozzle and one or more male connectors 4 for connecting the water supply hose are provided on the four - axis rotating body 2; wherein,

[0029] The support assembly includes multiple support feet 11 and a chassis 7. One end of each of the multiple support feet 11 is rotatably and foldably connected to the chassis 7, and the other ends extend outward in a divergent shape and are evenly distributed in the circumferential direction. The four - axis rotating body 2 is detachably installed on the chassis 7.

[0030] Through the above - mentioned technical solution, the four - axis rotating body 2 adopts an integrated body with adjustable angles up and down, left and right, and is hollow inside to allow water flow. Different models of hose nozzles (with the same interface) can be directly connected to the female connector 1, and the water hose is connected to the male connector 4. The installation and disassembly are fast, stable, and reliable. According to different terrains, the multiple support feet 11 are adjusted, and their independent support structures and angles are utilized to be suitable for fire rescue guarantees in all terrains. At the same time, the support feet 11 can be folded, so that the fire hose nozzle base can be integrally stored, which is convenient to use and move. After fixing the position, by rotating the four - axis rotating body 2, the up, down, left, and right water outlet angles of the hose nozzle can be adjusted, without the need for fire rescue personnel to hold it by hand, reducing the physical consumption of fire rescue personnel, and even being able to extinguish fires independently, releasing more rescue forces.

[0031] In this embodiment, preferably, a hand - tightened bolt 6 is provided at the connection between the four - axis rotating body 2 and the chassis 7, and the hand - tightened bolt 6 is set to be able to lock or loosen the rotation angle of the four - axis rotating body 2 by rotation.

[0032] In this embodiment, preferably, the support feet 11 are rotatably and foldably connected to the chassis 7 through a rotating shaft 9. A catch bolt 10 is further provided on the chassis 7, and a positioning hole is provided at a position on the support feet 11 close to the rotating shaft 9. The positioning hole is configured to be able to cooperate with the catch bolt 10 and penetrate through.

[0033] In this embodiment, preferably, the support assembly further includes a spring washer 8. The spring washer 8 passes through the rotating shaft 9 and connects the support feet 11 to the chassis 7.

[0034] In this embodiment, preferably, the fixed area formed after multiple support feet 11 are unfolded is spherical.

[0035] In this embodiment, preferably, a ground claw 12 is provided at the end of each support foot 11. A bolt hole is provided on the ground claw 12, and it is detachably connected to the support foot 11 through a bolt.

[0036] In this embodiment, preferably, the area of the ground claw 12 in contact with the support foot 11 is spherical, and the diameter of the bolt hole is larger than the diameter of the bolt.

[0037] In this embodiment, preferably, a plurality of second handles 5 are provided on the chassis 7.

[0038] In this embodiment, preferably, the plurality of second handles 5 are evenly arranged on the chassis 7 in the circumferential direction.

[0039] In this embodiment, preferably, a first handle 3 is provided on the four-axis rotating fuselage 2. One end of the first handle 3 is fixedly connected to the four-axis rotating fuselage 2, and the other end extends towards the fire fighting operation area.

[0040] During assembly, the ground claw 12 is fixed to the support leg 11 by bolts, and the ground claw 12 can be rotated by a certain angle according to requirements. Among them, since the fixing area of the support leg 11 is spherical, the contact area between the ground claw 12 and the support leg 11 is also spherical. Moreover, the hole in the ground claw 12 (bolt through-hole) is much larger than the bolt diameter, so the ground claw 12 can freely rotate along the center of the spherical surface to adapt to different angles. The support leg 11 is installed on the chassis 7 through a rotating shaft 9, and a spring washer 8 is installed on the rotating shaft 9 to increase the frictional force of rotation between the support leg 11 and the chassis 7, playing a damping role. The detent bolt 10 is installed on the chassis 7 for limiting the support leg 11. Specifically, a positioning hole is provided at a position on the support leg 11 close to the rotating shaft 9. When the support leg 11 rotates to an appropriate position, it penetrates through the detent bolt 10 installed on the chassis 7 to complete the fixation. The second handle 5 is installed on the chassis 7 and is used for holding when moving the device; the four-axis rotating body 2 is installed on the chassis 7 and is locked by a hand-tightening bolt 6; the male connector 4 is installed on the four-axis rotating body 2 and is used for connecting the water supply hose; the female connector 1 is installed on the four-axis rotating body 2 and is used for connecting the water gun; the first handle 3 is installed on the four-axis rotating body 2 and is used for adjusting the angles of the four-axis rotating body 2 in the up, down, left, and right directions, thereby changing the spraying angle of the water gun.

[0041] During the specific use process, the rescue personnel can rotate the support leg 11 upward until it contacts and is fixed to the chassis 7, then place it on a flat surface, and then assemble the four-axis rotating body 2 to the chassis 7, adjust the angle, tighten the hand-tightening bolt 6, and fix the angle of the four-axis rotating body 2. Then, connect the water hose to the male connector 4 and connect the water gun to the female connector 1. At this time, the overall assembly is completed. According to the actual combat requirements, different types of water guns can be replaced at any time, such as a straight-stream water gun, a spray water gun, or a multi-purpose water gun. After use, disconnect the water hose from the male connector 4, disconnect the water gun from the female connector 1, unscrew the hand-tightening bolt 6, remove the four-axis rotating body 2 and drain the accumulated water inside the four-axis rotating body 2. Finally, rotate the support leg 11 downward to the vertical position and make the detent of the detent bolt 10 completely coincide with the positioning hole of the support leg 11 to complete the storage.

[0042] It can be seen that the fire hose base can free the hands of firefighters. The fire hose can be safely and stably placed at any designated position without the need for a very flat ground. The up, down, left, and right water outlet angles of the water gun can be adjusted by holding the first handle 3. At the same time, the fire hose base can be integrally stored, is convenient to use, and is easy to move. Structurally, the support feet 11 of the fire hose base are designed with an extended length. In cooperation with the ground claws 12 in contact with the ground, the angle can be adjusted, and the overall stability is reliable. The material of the ground claws 12 can be selected as highly wear-resistant metal to reduce surface wear and extend its service life. Each ground claw 12 has an independent support structure, and the angle of contact with the ground can be adjusted according to different terrains to increase the friction with the ground, which is completely suitable for fire rescue support in all terrains. After using the fire hose base, there is no need for firefighters to hold the water gun during the entire fire extinguishing process. Just directly install the water gun on the fire hose base and adjust the water gun spraying angle to work normally, which greatly reduces the physical consumption of firefighters. In addition, the fire hose base can cooperate with different types of water guns. Specifically, according to actual combat needs, multiple points can be arranged simultaneously for water spraying to extinguish fires and reduce the temperature. As long as the interfaces of different models of water guns are the same, they can be directly connected to the female connector 1 for use. With a universal quick-release interface, the disassembly and assembly are convenient, stable, and reliable.
