[0021] like Figures 1 to 4 As shown, the present invention relates to a rotary pressure-stabilizing indoor fire hydrant, which includes a fire hydrant body 1 and a connecting mechanism 2. In this embodiment, the fire hydrant body 1 is an existing rotary pressure-stabilizing indoor fire hydrant on the market.

[0022] like Figure 1 As shown, the connecting mechanism 2 is located at the water outlet end of the fire hydrant body 1.

[0023] Specifically, such as Figures 1 to 3 As shown, the connecting mechanism 2 includes a mounting plate 201 fixedly sleeved on the surface of the water outlet end of the fire hydrant body 1. A support pipe 202 is fixedly connected to the mounting plate 201 on the opposite side of the water outlet end of the fire hydrant body 1. A connecting pipe 203 is sleeved on the surface of the support pipe 202 opposite to the mounting plate 201. One end of the connecting pipe 203 is fixedly connected to the mounting plate 201. A pressure block 204 is movably connected to the other end of the mounting plate 201. A tightening ring 205 is spirally sleeved on the outer wall of the connecting pipe 203. Several pressure blocks 204 have threads 2041 on their outer walls that are adapted to the tightening ring 205. A clamping cavity is formed at the opposite end of the support pipe 202. Several actuating rods 206 are fixedly connected at equal intervals on the outer wall of the tightening ring 205. When connecting the water pipe to the outlet end of the fire hydrant body 1, one end of the water pipe is sleeved on the surface of the support pipe 202, so that one end of the water pipe is in the clamping cavity formed by several pressure blocks 204 and the opposite end of the support pipe 202. Hold the actuating rods 206 and rotate the tightening ring 205 to make the tightening ring 205 spirally move from the connecting pipe 203 to the thread 2041 on the surface of the pressure block 204, so that one end of the pressure block 204 flips towards the surface of the support pipe 202, and cooperates with the support pipe 202 to clamp and fix the water end.

[0024] Furthermore, such as Figure 2 As shown, the pressure block 204 is arc-shaped, and the center of several pressure blocks 204 is on the same axis as the center of the connecting pipe 203, so that the tightening ring 205 can move spirally to the surface of the pressure block 204.

[0025] Furthermore, such as Figure 2 , Figure 4As shown, the support pipe 202 is provided with a plurality of compression rings 2021 at equal intervals on the surface of the opposite end of the compression block 204, and the compression block 204 is provided with a compression strip 2042 at a position opposite to the compression ring 2021. The compression ring 2031 is in the shape of a right-angled triangle in cross section, and the compression strip 2042 is in the shape of an inverted right-angled triangle in cross section. The inclined surface of the compression ring 2031 is opposite to the inclined surface of the compression strip 2042. When the fire hydrant body 1 is first opened, the water pressure inside is large, and it is difficult to ensure that the water pipe is in a flat state at the fire scene. Therefore, the water pipe is easily detached from the connecting mechanism 2 due to the large water pressure. By arranging the compression ring 2031 in the shape of a right-angled triangle in cross section and the compression strip 2042 in the shape of an inverted right-angled triangle in cross section, and by arranging the inclined surface of the compression ring 2031 opposite to the inclined surface of the compression strip 2042, the inner wall and the outer wall of the water pipe end can form a compression groove in the shape of a right-angled triangle in cross section and a compression groove in the shape of an inverted right-angled triangle in cross section during the tightening process of the tightening ring 205. Thus, the water pipe is firmly fixed in the clamping cavity formed by the plurality of compression blocks 204 and the opposite end of the support pipe 202.

[0026] Further, as shown in the drawings, Figure 2 The compression block 204 is fixedly connected with a connecting block 2043 at the opposite end of the connecting pipe 203. The connecting pipe 203 is provided with a connecting cavity 2031 for connecting the outside and the inside of the connecting pipe 203 at a position opposite to the connecting block 2043. One end of the connecting block 2043 extends into the connecting cavity 2031 and is rotatably connected with the inner walls of the connecting cavity 2031 on both sides. The tightening ring 205 is spirally moved from the connecting pipe 203 to the thread 2041 on the surface of the compression block 204, thereby driving the connecting block 2043 at one end of the compression block 204 to flip inside the connecting cavity 2031 towards the surface of the support pipe 202.

[0027] Working principle: the embodiment provides a rotating type stable pressure indoor fire hydrant. When in use, one end of the water pipe is sleeved on the surface of the support pipe 202, and the water pipe end is in the clamping cavity formed by the plurality of compression blocks 204 and the opposite end of the support pipe 202. The tightening ring 205 is rotated by holding the rotating rod 206, so that the tightening ring 205 is spirally moved from the connecting pipe 203 to the thread 2041 on the surface of the compression block 204, thereby driving the connecting block 2043 at one end of the compression block 204 to flip inside the connecting cavity 2031 towards the surface of the support pipe 202. The one end of the compression block 204 is flipped towards the surface of the support pipe 202, thereby driving the compression ring 2031 and the compression strip 2042 to form a compression groove in the shape of a right-angled triangle in cross section and a compression groove in the shape of an inverted right-angled triangle in cross section on the inner wall and the outer wall of the water pipe end, respectively. Thus, the water pipe is firmly fixed in the clamping cavity formed by the plurality of compression blocks 204 and the opposite end of the support pipe 202.
