However, in actual application, the phenomenon of accidental touch is very likely to occur, which affects the use effect of the water gun and may also increase the difficulty and risk of fire fighting operations to a certain extent.

[0004] In view of the above problems, the utility model proposes a flow rate adjusting structure for a fire fighting direct current spray water gun. Content of the Utility Model

[0005] The purpose of the utility model is to provide a flow rate adjusting structure for a fire fighting direct current spray water gun, thereby solving the problems in the background technique.

An adjusting component is arranged on the outer wall of the control handle. The adjusting component includes a mounting block fixedly connected in the cavity of the water gun main body. A pressure adjusting pipe is rotatably connected to the inner wall of the mounting block. A control rod is slidably connected to the inner wall of the pressure adjusting pipe. One end of the control rod far from the pressure adjusting pipe is fixedly connected with a control button;

[0007] A fixing block is arranged on the outer wall of the control rod, and a fixing groove is arranged on the inner wall of the pressure adjusting pipe.

[0008] Preferably, a return spring is sleeved on the outer wall of the control rod. One end of the return spring is fixedly connected with the control button, and the other end thereof is fixedly connected with the outer wall of the control handle.

[0009] Preferably, the pressure adjusting pipe penetrates through the control handle, and the diameter of the return spring is larger than the diameter of the through opening of the control handle.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] A flow rate adjustment structure for a fire fighting direct current spray water gun proposed by the present utility model. Press the control button, and the control button drives the control rod to move on the inner wall of the pressure adjustment pipe, driving the fixed block to gradually approach the fixed slot.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0022] Please refer to Figures 1 - 4 , in order to solve the problem that in actual applications, the phenomenon of accidental touch is very likely to occur, which affects the use effect of the water gun and may also increase the difficulty and risk of fire extinguishing operations to a certain extent, the following preferred technical solutions are provided:

[0023] A flow rate adjustment structure for a fire fighting direct current spray water gun includes a water gun main body 1 and a control handle 2 provided at one end of the water gun main body 1. An adjustment assembly 3 is provided on the outer wall of the control handle 2. The adjustment assembly 3 includes a mounting block 31 fixedly connected to the cavity of the water gun main body 1. A pressure adjustment pipe 32 is rotatably connected to the inner wall of the mounting block 31. A control rod 33 is slidably connected to the inner wall of the pressure adjustment pipe 32. A control button 34 is fixedly connected to the end of the control rod 33 away from the pressure adjustment pipe 32. A fixing block 36 is provided on the outer wall of the control rod 33, and a fixing groove 37 is provided on the inner wall of the pressure adjustment pipe 32.

[0024] A return spring 35 is sleeved on the outer wall of the control rod 33. One end of the return spring 35 is fixedly connected to the control button 34, and the other end is fixedly connected to the outer wall of the control handle 2. The pressure adjustment pipe 32 penetrates through the control handle 2, and the diameter of the return spring 35 is greater than the diameter of the through opening of the control handle 2. The sizes of the fixing block 36 and the fixing groove 37 match each other, and the fixing block 36 is a component made of rubber material.

[0025] A middle partition block 39 is fixedly connected to the inner wall of the control rod 33. Inner rods 310 are fixedly connected to both sides of the middle partition block 39. A elastic element 311 is sleeved on the outer wall of the inner rod 310. An outer support block 312 is fixedly connected to the end of the elastic element 311 away from the middle partition block 39. The outer support block 312 is fixedly connected to the fixing block 36. A movable channel 313 is provided at the end of the outer support block 312 close to the elastic element 311, and the inner wall of the movable channel 313 is slidably connected to the inner rod 310.

[0026] Specifically, by squeezing the control handle 2, the water gun body 1 can be driven to spray. When it is necessary to adjust the flow rate, the control button 34 needs to be pressed. The control button 34 drives the control rod 33 to move on the inner wall of the pressure regulating pipe 32, driving the fixed block 36 to gradually approach the fixed groove 37. When the fixed block 36 moves to the same horizontal line as the fixed groove 37, the fixed block 36 will elastically snap into the fixed groove 37 by itself. At this time, the pressure regulating pipe 32 can be driven to rotate by rotating the control button 34, thereby adjusting the flow area in the cavity, changing the pressure, and achieving the purpose of adjusting the flow rate. After the adjustment is completed, the control button 34 is released, and the control button 34 will be driven to return to its original position by the acting force of the return spring 35, so that the fixed block 36 is disengaged from the fixed groove 37. At this time, rotating the control button 34 cannot drive the pressure regulating pipe 32 to rotate, which can avoid the phenomenon of accidental touch. The effect is remarkable, solving the problem that in actual application, the phenomenon of accidental touch is very likely to occur, affecting the use effect of the water gun, and may also increase the difficulty and risk of fire extinguishing operations to a certain extent.

[0027] When the control rod 33 moves on the inner wall of the pressure regulating pipe 32, the fixed block 36 will be pressed to drive the movable channel 313 of the outer support block 312 to retract the inner rod 310, thereby compressing the elastic element 311. Therefore, when the fixed block 36 moves to the same horizontal line as the fixed groove 37, due to the reaction force of the elastic element 311, the fixed block 36 will be further tightly clamped in the fixed groove 37 through the outer support block 312, improving the fixing effect and ensuring the stability of the operation.

[0028] To sum up: When it is necessary to adjust the flow rate, the control button 34 needs to be pressed. The control button 34 drives the control rod 33 to move on the inner wall of the pressure regulating pipe 32, driving the fixed block 36 to gradually approach the fixed groove 37. When the fixed block 36 moves to the same horizontal line as the fixed groove 37, the fixed block 36 will elastically snap into the fixed groove 37 by itself. At this time, the pressure regulating pipe 32 can be driven to rotate by rotating the control button 34, thereby adjusting the flow area in the cavity, changing the pressure, and achieving the purpose of adjusting the flow rate. After the adjustment is completed, the control button 34 is released, and the control button 34 will be driven to return to its original position by the acting force of the return spring 35, so that the fixed block 36 is disengaged from the fixed groove 37. At this time, rotating the control button 34 cannot drive the pressure regulating pipe 32 to rotate, which can avoid the phenomenon of accidental touch. When the control rod 33 moves on the inner wall of the pressure regulating pipe 32, the fixed block 36 will be pressed to drive the movable channel 313 of the outer support block 312 to retract the inner rod 310, thereby compressing the elastic element 311. Therefore, when the fixed block 36 moves to the same horizontal line as the fixed groove 37, due to the reaction force of the elastic element 311, the fixed block 36 will be further tightly clamped in the fixed groove 37 through the outer support block 312.
