[0026] The utility model embodiment provides a self-cooling conversion interface, such as Figure 1-5As shown, it includes a conversion interface pipe 1, one end of the conversion interface pipe 1 is integrally formed with a reverse water spray ring 2, an inner concave cavity is opened on the inner side wall of the reverse water spray ring 2, and a self-cooling water spray hole 3 is opened on the outer wall of one side of the reverse water spray ring 2 at a position close to the conversion interface pipe 1, the self-cooling water spray hole 3 and the inner concave cavity are connected, a first flange 4 is welded on the end of the reverse water spray ring 2 away from the conversion interface pipe 1, and a second flange 5 is welded on the other end of the conversion interface pipe 1. A fire hose nozzle (not shown in the figure) is fixed to the first flange 4 by bolts, and a fire hose (not shown in the figure) is fixed to the second flange 5 by bolts. A conversion adjustment sleeve 6 is sleeved on the outer side of the conversion interface pipe 1, and a sealing groove 7 is opened on the outer side wall of the conversion interface pipe 1. The inner wall of the conversion adjustment sleeve 6 is close to the sealing groove 7. A sealing ring 8 is integrally formed at the inner position, and a connecting column 9 is welded at a side position of the inner wall of one side of the conversion adjustment sleeve 6 near the sealing ring 8, a guide platform 10 is welded at one end of the connecting column 9 away from the conversion adjustment sleeve 6, a valve plate 11 is integrally formed on one side outer wall of the guide platform 10, a valve groove 12 is opened at an outer position of the inner wall of the conversion interface pipe 1 near the valve plate 11, a sealing ring 13 is integrally formed at one end of the conversion adjustment sleeve 6 near the reverse water spray ring 2, the outer radius and inner radius of the reverse water spray ring 2 and the sealing ring 13 are the same, a through groove 19 is opened on the outer wall of one side of the conversion interface pipe 1 near the outer position of the connecting column 9, and there are four through grooves 19 in total, and the four through grooves 19 are symmetrically opened on the outer wall of the conversion interface pipe 1, and the connecting column 9 passes through the through groove 19.
[0027] It should be noted that, since most of the existing fire hoses use switch valves to cut off the water flow and adjust the water pressure, the switch valve has a single function and can only control the water flow in one direction. When firefighters are extinguishing fires, the ambient temperature of the firefighters is high and the body temperature of the firefighters themselves will rise rapidly. Firefighters need to cool down, which increases the firefighting time and worsens the firefighting effect. This embodiment can replace the traditional switch valve through the self-cooling conversion interface, and use a push-pull structure to achieve on-off control of the water flow and control of the water flow pressure. The control is also simpler and more convenient, and only needs to be pushed or pulled. By controlling the blocking state of the self-cooling water spray hole 3, a reverse water flow can be provided to the firefighters when they are extinguishing the fire, and part of the water can be used to spray the firefighters, which is beneficial to cooling the firefighters' body temperature, increasing the firefighting time and improving the firefighting effect.
[0028] Specifically, in the present embodiment, the scheme mainly includes a conversion interface pipe 1 and a conversion adjustment sleeve 6. When it is necessary to control the internal passage of the conversion interface pipe 1, the conversion adjustment sleeve 6 is pulled away from the reverse water spray ring 2, and the conversion adjustment sleeve 6 is pulled outside the conversion interface pipe 1. The sealing ring 8 and the connecting column 9 on the conversion adjustment sleeve 6 move synchronously, and the sealing ring 8 moves in the sealing groove 7. The matching fit between the sealing ring 8 and the sealing groove 7 can ensure the sealing between the conversion interface pipe 1 and the conversion adjustment sleeve 6 to avoid water leakage. The guide platform 10 at one end of the connecting column 9 moves synchronously, and the valve plate 11 on the guide platform 10 moves away from the inner side wall of the valve slot 12. The gap between the valve slot 12 and the valve plate 11 increases, and the water on one side of the guide platform 10 flows through the gap. The water flows through the valve plate 1 1, realize the opening of the internal passage of the conversion interface pipe 1, and a part of the water flow enters the reverse water spray ring 2. Due to the movement of the conversion adjustment sleeve 6, the sealing ring 13 on the conversion adjustment sleeve 6 is separated from the reverse water spray ring 2, and the water flow is ejected through the self-cooling water spray hole 3. The self-cooling water spray hole 3 inclined at 45 degrees can make the water flow fully hit the firefighter, which is beneficial to cool the body temperature of the firefighter, increase the fire fighting time, and improve the fire fighting effect. When it is necessary to close the internal passage of the conversion interface pipe 1, it is only necessary to push the conversion adjustment sleeve 6 in the reverse direction. The sealing ring 13 on the conversion adjustment sleeve 6 is squeezed on the outer side of the reverse water spray ring 2 to achieve the sealing of the self-cooling water spray hole 3. The valve plate 11 is squeezed on the inner wall of the valve slot 12, and the gap value between the valve plate 11 and the valve slot 12 is 0, so that the internal passage of the conversion interface pipe 1 is closed.
[0029] The utility model embodiment provides a self-cooling conversion interface, such as Figure 1-4 and Figure 6-7 As shown, it includes a conversion interface tube 1 and a conversion adjustment sleeve 6, a handle 14 is screwed on one side outer wall of the conversion adjustment sleeve 6 through a threaded connection, two handles 14 are provided, and the two handles 14 are symmetrically arranged on the outer side wall of the conversion adjustment sleeve 6, a spring 15 is provided at the inner central position of the handle 14, a pin 16 is provided at one end of the spring 15, a recessed hole for accommodating the spring 15 and the pin 16 is provided inside the handle 14, a pull ring 17 is integrally formed on one side outer wall of the pin 16, a movable groove is provided on one side outer wall of the handle 14 near the outer side of the pull ring 17, a pin hole 18 is provided on one side outer wall of the conversion interface tube 1 near the pin 16, and one end of the pin 16 can be embedded in the pin hole 18.
[0030] Specifically, in the present embodiment, the scheme mainly includes a handle 14. When the conversion adjustment sleeve 6 is pushed and pulled, the handle 14 is held and the thumb is inserted into the pull ring 17. When it is necessary to push and pull the conversion adjustment sleeve 6, the pull ring 17 is first pulled with the thumb, and the pin 16 on the pull ring 17 moves synchronously. The spring 15 is compressed, and the pin 16 is pulled out of one of the pin holes 18. Then the conversion adjustment sleeve 6 is pushed and pulled again. When the conversion adjustment sleeve 6 moves to the desired position, the pull ring 17 is released, and the pin 16 is inserted into another pin hole 18 under the action of the rebound force of the spring 15, so as to realize the fixing of the position of the conversion adjustment sleeve 6 on the outer wall of the conversion interface tube 1, thereby ensuring the stability of the opening of the internal channel of the conversion interface tube 1.
