It is one of the indispensable pipeline accessories to ensure normal production and product quality.

[0003] At present, when the water flow indicator of the fire-fighting equipment is installed, the water flow indicator is fixed by a U-shaped pipe clamp. However, the U-shaped pipe clamp is used to fix the water flow indicator by rotating both sides by nuts. When the nuts on both sides are rotated, the nuts on both sides cannot be rotated at the same time, which causes the other side to easily warp up when the nuts are removed for rotation and fixing, and the removal of the warped part is prone to poor sealing.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water flow indicator for fire-fighting equipment, comprising a water flow indicator, a pipe and a circular plate, wherein a pipe is arranged at the bottom end of the water flow indicator, a circular plate is arranged at the inner center of the pipe, and the top of the circular plate is connected to the water flow indicator, and the water flow indicator for fire-fighting equipment also includes: a clamping mechanism, which is arranged at the bottom end of the pipe; and a fixing mechanism, which is arranged at the center of the clamping mechanism.

[0006] The screw is fitted on the bottom end of the slot block, and then the user rotates the screw, which is inserted into the slot block when the screw rotates, and then drives the frame to move upward. When the frame moves upward, it drives the rotating rod and the baffle to pass through the bottom end of the through slot of the water flow indicator.

[0007] Preferably, through grooves are provided inside both sides of the water flow indicator.

[0008] Preferably, a thread groove is provided inside the groove block.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model is arranged such that when the water flow indicator of the fire-fighting equipment is put into use, the water flow indicator is clamped by using the clamping mechanism, and the clamping mechanism is pulled down tighter by using the fixing mechanism. Through the coordinated use of the above components, the problem that the nuts on both sides of the current water flow indicator cannot be rotated and fixed at the same time when being fixed by a U-shaped pipe clamp is solved, and the problem that the other side of the removed nut is easily lifted up when being rotated and fixed, resulting in poor sealing, is solved.

[0017] Specifically, the clamping mechanism 4 includes: a frame 401, a rotating rod 402, a baffle 403 and a protrusion 404;

[0018] The frame 401 is arranged at the bottom end of the pipe 2, and the frame 401 is used to support the rotating rod 402. The rotating rod 402 is rotatably arranged at the top ends of both sides of the frame 401, and the rotating rod 402 can drive 403 to rotate. The baffle 403 is fixedly arranged at the top end of the rotating rod 402. After the baffle 403 is rotated, it can be clamped on both sides of the water flow indicator 1 through the protrusion 404, and the protrusion 404 is fixedly arranged on both sides of the bottom end of the baffle 403. When the rotating rod 402 rotates, the angle of the baffle 403 can be adjusted, and then the baffle 403 can be adjusted to the angle corresponding to the through grooves on both sides of the water flow indicator 1, and then it can pass through its bottom end.

[0019] More specifically, the fixing mechanism 5 includes: a screw 501, a top plate 502, a slot block 503 and a connecting block 504;

[0020] The screw 501 is inserted and set inside the center of the frame 401. When the screw 501 rotates, it can drive the top plate 502 to push the frame 401 downward. The top plate 502 is rotatably set on the outer wall of the screw 501, and the top plate 502 is set at the top of the frame 401. The groove block 503 is threadedly set on the top outer wall of the screw 501. The connecting block 504 is fixedly set at the bottom end of the groove block 503, and the top end of the connecting block 504 is fixedly connected to the bottom end of the pipe 2.
