DETAILED DESCRIPTION

[0024] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0025] like Figure 1 As shown, the utility model provides a rotatable fire hydrant, comprising a support seat 1, a fire hydrant body 2 rotatably mounted on the upper end of the support seat 1, and a water inlet pipe 6 arranged in the support seat 1. The side surface of the fire hydrant body 2 is provided with a plurality of water outlet joints 4 for conveying fire water, each of which is sleeved with an end cover 5. The water inlet pipe 6 is movably connected with a sleeve 7 in the fire hydrant body 2, and the sleeve 7 is connected with the water outlet joint 4, and the fire water is input into the water outlet joint 4 through the sleeve 7;

[0026] In this embodiment, a sealing ring 3 is sleeved on the water pipe 6, and the sealing ring 3 fits with the inner ring of the sleeve 7;

[0027] In this embodiment, the water inlet pipe 6 and the sleeve 7 are both made of stainless steel, so that the water inlet pipe 6 and the sleeve 7 have good wear resistance.

[0028] like Figures 1 to 4 As shown, in this embodiment, the outer top of the support seat 1 and the outer bottom of the fire hydrant body 2 are respectively and horizontally fixedly mounted with a first convex ring 10 and a second convex ring 11;

[0029] A plurality of fixed blocks 17 connected to the fire hydrant body 2 are arranged in an annular shape at equal intervals above the second convex ring 11, and a plurality of grooves 12 are vertically opened in an annular shape at equal intervals on the second convex ring 11, and two sliding rings 13 distributed up and down are slidably installed in each groove 12, and the two sliding rings 13 can slide vertically up and down along the inner wall of the groove 12, and the upper and lower opposite surfaces of the two sliding rings 13 are connected by a spring 14, wherein a clamping rod 15 is fixedly installed in the sliding ring 13 at the lower end, and an adjusting bolt 18 is horizontally rotatably installed on the sliding ring 13 at the upper end;

[0030] The clamping rod 15 movably penetrates the inner bottom of the groove 12, and the clamping rod 15 movably extends into the clamping groove 16 opened on the top surface of the first convex ring 10, and the position of the second convex ring 11 can be fixed by the clamping rod 15 and the clamping groove 16, so as to reduce the fire hydrant body 2 from rotating at will;

[0031] The adjusting bolt 18 cooperates with the inner thread of the screw hole 19 provided on the fixing block 17, so that the position of the upper end sliding ring 13 can be adjusted by adjusting the adjusting bolt 18 and the screw hole.

[0032] In this embodiment, a convex tube 8 is provided on the top of the support seat 1, and the convex tube 8 is movably extended into the fire hydrant body 2, and the convex tube 8 provides auxiliary positioning for the fire hydrant body 2, thereby improving the stability of the fire hydrant body 2 when rotating horizontally;

[0033] In this embodiment, a plurality of balls 9 are movably embedded in the side surface of the convex tube 8, and the balls 9 are rollingly connected with the inner ring of the fire hydrant body 2, so as to reduce the friction between the convex tube 8 and the inner wall of the fire hydrant body 2, which is conducive to faster rotation of the fire hydrant body 2;

[0034] The outer bottom of the clamping rod 15 is a hemispherical structure, and the inside of the clamping slot 16 is a corresponding arc shape, so that the clamping slot 16 can squeeze and push the clamping rod 15 to move upward;

[0035] The top surface of the first convex ring 10 is provided with more than two clamping grooves 16, and the clamping grooves 16 on the first convex ring 10 are distributed in an annular shape with equal spacing, so that the clamping rod 15 can cooperate with different clamping grooves 16 to fix the second convex ring 11 at different positions;

[0036] The side surfaces of the first convex ring 10 and the second convex ring 11 are flush, which improves the overall aesthetics of the fire hydrant;

[0037] The spring 14 is parallel to the inner side of the groove 12, and the outer diameter of the spring 14 is smaller than the inner diameter of the groove 12, so that the spring 14 can be elastically deformed in the groove 12 and the collision between the spring 14 and the inner wall of the groove 12 can be reduced when the spring 14 is deformed by pressure.

[0038] Specifically, when in use, the support base 1 drives the fire hydrant body 2 to be installed at an appropriate position, and the external water pipe is connected to the water inlet pipe 6;

[0039] Then the angle of the water outlet joint 4 can be adjusted. The water outlet joint 4 can be driven to rotate by rotating the fire hydrant body 2, so as to adjust the angle of the water outlet joint 4. When the fire hydrant body 2 rotates, the sleeve 7 is driven to rotate horizontally. At the same time, the fire hydrant body 2 drives the second convex ring 11, each spring 14 and the clamping rod 15 to rotate horizontally. When the clamping rod 15 rotates, it overcomes the elastic force of the spring and drives the sliding ring 13 at the bottom to move upward. When the fire hydrant body 2 and the water outlet joint 4 rotate to the specified position, the clamping rod 15 is subjected to the elastic force of the spring 14 to enter the corresponding clamping groove 16. If the clamping rod 15 is not facing the clamping groove 16 at this time, the fire hydrant body 2 can be fine-tuned so that the clamping rod 15 enters the nearest clamping groove 16. The second convex ring 11 is fixed in position by the locking rod 15 in cooperation with the locking groove 16, so that the second convex ring 11 drives the fire hydrant body 2 to be fixed in position, thereby reducing the situation where the fire hydrant rotates at will, and the initial compression state of the spring 14 can be adjusted as needed, and the upper sliding ring 13 can be driven to move vertically in the groove 8 by rotating the adjusting bolt 18, so that the pressure applied by the upper sliding ring 13 to the spring 14 changes, and the initial compression state of the spring 14 changes, so that the elastic force of the spring 14 that needs to be overcome when the fire hydrant body 2 rotates occurs easily, so as to make the position of the fire hydrant body 2 more stable or make the fire hydrant body 2 more convenient to rotate according to actual needs, thereby improving the flexibility of the fire hydrant;

[0040] After the water outlet joint 4 is adjusted, the end cover 5 is removed, and the fire hose is connected to the water outlet joint 4 to input fire water through the water inlet pipe 6 of the external water pipe box, and the valve on the fire hydrant body 2 is opened. The fire water is sprayed out through the casing 7, the water outlet joint 4 and the fire hose to extinguish the fire.
