[0024] Embodiment 1

[0025] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown in the figure, the present utility model provides a technical solution: a direct-through indoor fire hydrant for fire fighting, which includes a valve body 1, a fixed chuck 9, and a water outlet pipe 12. A fixed ring 11 is fixedly connected to the right end of the outer surface of the water outlet pipe 12. A positioning claw 7 is hinged to the outer surface of the fixed ring 11. One end of the positioning claw 7 is fixedly connected to a pull block 10. An inner groove 18 is formed on the inner surface of the right end of the positioning claw 7. One side of the inner cavity of the inner groove 18 is fixedly connected to a second spring 19. The other end of the second spring 19 is fixedly connected to a positioning block 20. A water hose connection sleeve 8 is arranged on the outside of the fixed chuck 9. A positioning groove 17 is formed on the right side of the water hose connection sleeve 8;

[0026] Among them, a water outlet pipe 12 is arranged on the right side of the valve body 1. A fixed chuck 9 is arranged at the right end of the water outlet pipe 12. A sealing gasket 13 is arranged on the right side of the fixed chuck 9;

[0027] Among them, the number of the positioning claws 7 is four, and the included angle between two adjacent positioning claws 7 is ninety degrees;

[0028] Among them, the left end of the positioning block 20 is a hemisphere, and the positioning block 20 is adapted to the positioning groove 17.

[0029] Through the setting of the sealing gasket 13 in this technical solution, the sealing performance when the fixed chuck 9 and the water hose connection sleeve 8 are connected is ensured, avoiding the situation that fire fighting water easily overflows from their connection part, causing waste of water resources and insufficient pressure in the fire hose. Then, the pull block 10 drives the positioning claw 7 to flip, so that one end of it is clamped outside the water hose connection sleeve 8. At the same time, with the assistance of the second spring 19, the positioning block 20 will retract into the inner groove 18. After the position of the positioning claw 7 is determined, the second spring 19 will drive the positioning block 20 to reset, and the hemispherical end of the positioning block 20 will be stuck into the positioning groove 17, so as to be able to limit the position and prevent the water hose connection sleeve 8 from falling off.

[0030] Embodiment Two

[0031] On the basis of Embodiment One, as shown in the present utility model Figure 1 、 Figure 3 and Figure 4 a positioning seat 2 is fixedly connected to the left end of the top of the valve body 1. A first spring 16 is fixedly connected to the bottom of the inner cavity of the positioning seat 2. The top of the first spring 16 is fixedly connected to a movable block 14. A positioning pin rod 15 is fixedly connected to the top of the movable block 14. A push block 3 is fixedly connected to the lower end of the left side of the movable block 14. A valve rod 6 is arranged inside the valve body 1. A runner 4 is fixedly connected to the upper end of the outer surface of the valve rod 6. A positioning hole 5 is formed on the inner surface of the runner 4;

[0032] Among them, the positioning hole 5 is adapted to the positioning pin rod 15, and the positioning pin rod 15 slides inside the positioning hole 5.

[0033] Through the setting of the rotating wheel 4, the opening and closing of this fire hydrant are facilitated. When this fire hydrant is closed, the push block 3 drives the movable block 14 to retract into the positioning seat 2 and can compress the first spring 16. After the rotating wheel 4 drives the valve rod 6 to rotate to the closed position, the push block 3 is released. At this time, the first spring 16 will drive the movable block 14 to reset upward in the positioning seat 2, and the movable block 14 will drive the positioning pin rod 15 to insert into the positioning hole 5, so as to limit the position of the valve rod 6 through the rotating wheel 4, and can avoid the situation that the valve rod 6 becomes loose or children accidentally open the valve body 1.

[0034] Working principle: Through the setting of the rotating wheel 4, the opening and closing of this fire hydrant are facilitated. When this fire hydrant is closed, the push block 3 drives the movable block 14 to retract into the positioning seat 2 and can compress the first spring 16. After the rotating wheel 4 drives the valve rod 6 to rotate to the closed position, the push block 3 is released. At this time, the first spring 16 will drive the movable block 14 to reset upward in the positioning seat 2, and the movable block 14 will drive the positioning pin rod 15 to insert into the positioning hole 5, so as to limit the position of the valve rod 6 through the rotating wheel 4. Through the setting of the sealing gasket 13, the sealing performance when the fixed chuck 9 and the water hose connection sleeve 8 are connected is guaranteed. Then, the positioning claw 7 is driven by the pull block 10 to turn over so that one end of it is stuck on the outside of the water hose connection sleeve 8. At the same time, with the assistance of the second spring 19, the positioning block 20 will retract into the inner groove 18. After the position of the positioning claw 7 is determined, the second spring 19 will drive the positioning block 20 to reset, and the hemispherical end of the positioning block 20 will be stuck into the positioning groove 17.
