[0021] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Please see Figures 1 to 3 An adjustable flow fire monitor head provided in one embodiment of the present invention includes a monitor head body 11 and a baffle 12 installed in the outlet end of the monitor head body 11. The monitor head body 11 is characterized in that a movable tube 13 is provided on the outer wall of the monitor head body 11, one end of the movable tube 13 is provided with a flow collecting sleeve 14, and the other end is threadedly connected to a rotation adjustment component 15.

[0024] The rotation adjustment component 15 is fixedly installed on the outer wall of the gun head body 11. When the rotation adjustment component 15 rotates, the movable tube 13 moves on the outer wall of the gun head body 11 to adjust the gap between the flow collecting sleeve 14 and the baffle 12.

[0025] It should be noted that, in use, this utility model uses a tool such as a crescent-shaped wrench to drive the rotation adjustment component 15 to rotate, so that the movable tube 13 moves forward or backward on the outer wall of the gun head body 11, and the gap between the flow collecting sleeve 14 and the baffle 12 changes, thereby achieving the purpose of adjusting the flow rate.

[0026] Please see Figures 1 to 3 In a preferred embodiment of this utility model, the movable tube 13 is provided with a strip-shaped sliding hole 131, and a pin 16 is provided on the outer wall of the gun head body 11, with the pin 16 located in the sliding hole 131. The pin 16 limits the movable tube 13, preventing it from rotating or falling off during movement.

[0028] One end of the inner wall of the adjusting ring 153 forms a bearing structure with a plurality of steel balls 152 and the support ring 151, and the other end of the inner wall is threadedly connected to the outer wall of the movable tube 13, so that when the adjusting ring 153 rotates in place, its own rotation can be converted into the movement of the movable tube 13.

[0029] Please see Figures 1 to 3 In a preferred embodiment of the present invention, the outer wall of the adjusting ring 153 is provided with a receiving hole for installing the steel ball, and a plug 154 is provided in the receiving hole to prevent the steel ball 152 from falling off.

[0030] Please see Figures 1 to 3 In a preferred embodiment of this utility model, a scale 155 is provided on the outer wall of the gun head body 11. The scale 155 is fitted with the end of the adjusting ring 153, and the outer wall of the adjusting ring 153 is provided with scale markings. By providing the scale 155 and the scale markings, the flow rate can be easily adjusted for reference.

[0031] Please see Figure 2 and Figure 3In a preferred embodiment of this utility model, a first waterproof ring 17 is provided between the inner wall of the movable tube 153 and the outer wall of the gun head body 11, thereby enhancing the sealing effect.

[0032] Please see Figure 2 and Figure 3 In a preferred embodiment of this utility model, a second waterproof ring 18 is provided between the outer wall of the movable tube 153 and the inner wall of the collecting sleeve 14, thereby enhancing the sealing effect.

[0033] Please see Figures 1 to 3 In a preferred embodiment of the present invention, a support frame 111 is provided on the inner wall of the outlet end of the gun head body 11, and the baffle 12 is installed on the support frame 111 by a double-headed screw 19.
