[0039] The two connecting blocks 2 are respectively fixed at the two ends of the top side of the outer shell of the flow meter body 1; the lateral ends of the two L-shaped plates 3 are respectively inserted into the slots 201 opened on the outside of the two connecting blocks 2; the two half clamping rings 4 are respectively fixed at the longitudinal ends of the two L-shaped plates 3, and the half clamping rings 4 are clamped on the externally connected pipes.

[0040] The utility model provides a connecting block 2, a slot 201, an L-shaped plate 3 and a half clamping ring 4. When the flow meter body 1 is installed, the L-shaped plate 3 is docked with the connecting block 2, and the two half clamping rings 4 are respectively clamped on the pipes on both sides to support the flow meter body 1. When connecting the flange, the staff only needs to hold the flange still to keep it stable for installation, which solves the problem of needing one staff to hold the shell of the electromagnetic flow meter while another staff connects the flange, thereby wasting labor.

[0041] Specifically, the inner side of the slot 201 is closed, and the insertion of the lateral end of the L-shaped plate 3 into the slot 201 is limited, so the lateral end of the L-shaped plate 3 is accurately inserted.

[0042] Furthermore, a limiting structure 5 is arranged on the top of the connecting block 2;

[0043] The limiting structure 5 includes an insert rod 501, a movable plate 502 and a spring 503;

[0044] The bottoms of the two insertion rods 501 are respectively inserted into two through holes A202 symmetrically opened on the top side of the connecting block 2; wherein the through hole A202 is connected to the slot 201; wherein the bottoms of the two insertion rods 501 are respectively inserted into two through holes B301 symmetrically opened at the lateral ends of the L-shaped plate 3, and the bottom ends of the insertion rods 501 abut against the inner bottom wall of the slot 201; the movable plate 502 is fixed to the top ends of the two insertion rods 501; the two springs 503 are respectively sleeved on the two insertion rods 501 between the bottom side of the movable plate 502 and the top side of the connecting block 2, and the two ends of the spring 503 are respectively fixedly connected to the bottom side of the movable plate 502 and the top side of the connecting block 2, and the elastic coefficient of the spring 503 is selected and used by the technicians in this profession according to actual conditions.

[0045] The utility model has the advantages of quickly positioning the lateral end of the L-shaped plate 3 inserted into the slot 201 and keeping the lateral end of the L-shaped plate 3 stably connected to the connecting block 2 by arranging the insertion rod 501, the movable plate 502, the spring 503, the through hole A202 and the through hole B301.

[0046] Furthermore, the limiting structure 5 further includes a vertical plate 504, a sliding groove 5041 and a sliding block 5021;

[0048] The utility model has the advantage of limiting the upward movement position of the movable plate 502 by setting the vertical plate 504, the sliding groove 5041 and the sliding block 5021, so that the bottom end of the insertion rod 501 does not separate from the through hole A202.

[0049] Working principle: When the device of the utility model is used, when the flow meter body 1 is installed between two pipes, the movable plate 502 is pulled upward, the rod 501 moves upward accordingly, the spring 503 is further stretched, and the slider 5021 moves up to the top along the slide groove 5041, and the bottom end of the rod 501 is located in the perforation A202; the lateral end of the L-shaped plate 3 is inserted into the slot 201 and inserted to the bottom, and the movable plate 502 is released. Under the action of the spring 503, the movable plate 502 drives the rod 501 to move downward, and the slider 5021 moves downward along the slide groove 5041, and the bottom of the rod 501 passes through the perforation A202 and the perforation B301 in sequence until the bottom end of the rod 501 contacts the bottom wall of the slot 201. The two half clamp rings 4 are clamped on the pipes on both sides respectively, and the flow meter body 1 is supported between the two pipes. The connecting flanges at both ends of the shell of the flow meter body 1 are connected with the flanges on the pipes. When connecting the flanges, the staff only needs to hold the flanges to keep the flow meter body 1 stable for installation. After the installation is completed, the movable plate 502 can be pulled up, and the lateral end of the L-shaped plate 3 can be pulled out and removed.
