When the two movable rings are merged, the connecting rod on one of the movable rings drives the arc-shaped clamping block to move horizontally, so that the arc-shaped clamping block squeezes the baffle rod on the other movable ring and is stuck on the baffle rod, thereby limiting the merged movable ring, thereby maintaining the stability of the upper and lower guard frames. Then, through the setting of the limit piece, the elastic rod is abutted against the surface of the lower guard frame, thereby further limiting the two movable rings.

[0014] (2) The display part of the flow meter is further protected by two arc-shaped shielding plates. The two movable rings are limited by limit blocks and sliding grooves to improve the stability of the movable rings during movement. After the two movable rings are combined, the first plug rod is inserted into the first circular groove to limit the two movable rings.

[0022] It is worth noting that a gap is left between the upper protective frame 7 and the lower protective frame 9 and the flow detector 2 after they are combined. In winter, materials such as thermal insulation cotton can be stuffed into the gap to improve the cold resistance of the flow detector 2.

[0023] Further as Figure 2 and Figure 3 As shown, it is worth explaining in detail that the limit member includes an elastic rod 13 rotatably connected to the top surface of one of the connecting rods 10, wherein an L-shaped fixing block 14 is fixed to the top surface of the other connecting rod 10, and the end of the elastic rod 13 is clamped with the L-shaped fixing block 14, and the surface of the elastic rod 13 is in contact with the surface of one of the lower guard frames 9.

[0024] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth explaining in detail that two symmetrically distributed limit blocks 3 are fixed on the surface of the tube body 1, and the inner walls of the two movable rings 4 are provided with sliding grooves 16 corresponding to the limit blocks 3. The limit blocks 3 are slidably connected to the inner walls of the sliding grooves 16, and the two movable rings 4 are limited by the limit blocks 3 and the sliding grooves 16 to improve the stability of the movable rings 4 during the movement; one side of the two upper guard frames 7 is fixed with an arc-shaped shield plate 8, and the two arc-shaped shield plates 8 are combined into a semicircle, and the two arc-shaped shield plates 8 further protect the display part of the flow detector 2; the surfaces of the two movable rings 4 are fixed with two symmetrically distributed pull rings 5, and the pull rings 5 ​​facilitate the movement of the movable rings 4.

[0027] This solution has the following working process: electromagnetic flowmeter is usually used to detect the water flow of the pipeline, but the electromagnetic flowmeter is often exposed to the outside world after being connected to the water pipe, and has poor protection. The electromagnetic flowmeter located at the construction site is easily bumped, which reduces the service life of the equipment and increases the expenditure. After the flow detector 2 is connected to the water pipe, the two movable rings 4 are pulled to make the two movable rings 4 move closer to each other, so that the two lower guard frames 9 and the two upper guard frames 7 are combined, and then the upper guard frame 7 and the lower guard frame 9 protect the flow detector 2. To protect and reduce external collisions, when the two movable rings 4 are merged, the connecting rod 10 on one of the movable rings 4 drives the arc-shaped clamping block 11 to move horizontally, so that the arc-shaped clamping block 11 squeezes the baffle rod 12 on the other movable ring 4 and is stuck on the baffle rod 12, thereby limiting the merged movable ring 4, and then maintaining the stability of the merging of the upper guard frame 7 and the lower guard frame 9, and then the staff clamps the end of the elastic rod 13 in the L-shaped fixing block 14, and the elastic rod 13 abuts against the surface of the lower guard frame 9, thereby further limiting the two movable rings 4.

[0028] According to the above working process, it can be known that: by merging the two lower guard frames 9 and the two upper guard frames 7, the upper guard frame 7 and the lower guard frame 9 protect the flow detector 2 to reduce external collisions. When the two movable rings 4 are merged, the connecting rod 10 on one of the movable rings 4 drives the arc-shaped clamping block 11 to move horizontally, so that the arc-shaped clamping block 11 squeezes the baffle rod 12 on the other movable ring 4 and is stuck on the baffle rod 12, thereby limiting the merged movable ring 4, thereby maintaining the stability of the merging of the upper guard frame 7 and the lower guard frame 9, and then through the setting of the limiting piece, the elastic rod 13 is abutted against the surface of the lower guard frame 9, thereby further limiting the two movable rings 4.
