[0028] The bottom of the anti-corrosion cover 1 is provided with a clearance groove 5 for the pipe of the electromagnetic water meter body to make way, and a baffle 3 for covering the pipe of the electromagnetic water meter body is fixedly installed on the outer wall of the anti-corrosion cover 1.

[0029] An installation opening is provided at the bottom of the anti-corrosion cover 1, and an anti-corrosion plate 4 is installed at the installation opening. The anti-corrosion plate 4 is fixed to the electromagnetic water meter body.

[0030] Multiple slots 14 are formed on the inner wall of the anti-corrosion cover 1 at the mounting port, and the anti-corrosion plate 4 is located between the multiple slots 14. In this embodiment, there are four slots 14, which are arranged in a cross shape.

[0031] Multiple second sliding grooves 10 are opened in the anti-corrosion plate 4. The multiple second sliding grooves 10 correspond one-to-one with multiple slots 14. Each second sliding groove 10 is equipped with a locking block 13 that engages with the corresponding slot 14.

[0032] Multiple mounting blocks 6 are fixedly installed on the bottom of the anti-corrosion plate 4. In this embodiment, there are four mounting blocks 6. Each mounting block 6 has a first groove 7 on its bottom, and the four first grooves 7 are arranged in a cross shape.

[0033] Each first slide groove 7 is provided with a telescopic support rod 9. Each first slide groove 7 is provided with a horizontally placed pivot 11, each pivot 11 is rotatably connected to the mounting block 6 and passes through the mounting block 6. Each telescopic support rod 9 is arranged radially along the pivot 11 in the first slide groove 7 and its non-telescopic end is fixedly connected to the pivot 11 in the first slide groove 7.

[0034] Each telescopic support rod 9 has a rotational damping between its non-telescopic end and the mounting block 6. The bottom of the mounting block 6 has a clearance hole 8 for engaging the telescopic support rod 9.

[0035] Each of the four telescopic support rods 9 corresponds one-to-one with a corresponding locking block 13. A transmission assembly is provided between each telescopic support rod 9 and its corresponding locking block 13 to drive the locking block 13 into the corresponding locking slot 14.

[0036] Specifically, the transmission assembly includes a cam 12 and a pusher block 15. A guide groove is provided at the bottom of the anti-corrosion plate 4. One end of the guide groove is connected to the end of the second slide groove 10 away from the slot 14, and the other end of the guide groove is connected to the outside. The pusher block 15 is slidably installed in the guide groove for limiting.

[0037] The end of the locking block 13 away from the locking slot 14 has a transmission ramp, and the push block 15 abuts against the transmission ramp for transmission. The cam 12 is coaxially and fixedly connected to the rotating shaft 11, and the cam 12 abuts against the push block 15 for transmission.

[0038] Multiple third slide grooves 17 are formed inside the corrosion-resistant plate 4. In this embodiment, there are four third slide grooves 17. The four third slide grooves 17 correspond one-to-one with the four second slide grooves 10. Each third slide groove 17 is connected to the corresponding second slide groove 10, and a reset component is installed in each third slide groove 17 to disengage the corresponding locking block 13 in the corresponding second slide groove 10 from the corresponding locking slot 14 and slide back.

[0039] Specifically, the reset assembly includes a reset spring 18. A slider 16 is slidably mounted within the third slide groove 17, and the slider 16 is fixedly connected to the locking block 13.

One end of the reset spring 18 is fixedly connected to the slider 16, and the other end is fixedly connected to the anti-corrosion plate 4.

[0040] Working principle: When installing this corrosion-resistant electromagnetic water meter, first place the corrosion-resistant cover 1 over the electromagnetic water meter body. Then, rotate the four telescopic support rods 9 out of the first sliding groove 7 and rotate them to be perpendicular to the corrosion-resistant plate 4.

[0041] After all the telescopic support rods 9 have rotated out of the first slide groove 7 and are perpendicular to the anti-corrosion plate 4, connect the anti-corrosion electromagnetic water meter to the pipeline. After the connection is completed, pull the telescopic end of the telescopic support rod 9 to make it abut against the installation location, thereby completing the support of the anti-corrosion electromagnetic water meter.

[0042] When the telescopic support rod 9 rotates out of the first slide groove 7, the rotating shaft 11 drives the cam 12 to rotate. The protrusion of the cam 12 pushes the push block 15 into the guide groove, and the push block 15 pushes the locking block 13 into the locking groove 14 through the transmission inclined surface, thus completing the locking. During this process, the locking block 13 drives the slider 16 to compress the return spring 18.

[0043] When it is necessary to remove the anti-corrosion cover 1, simply push back the telescopic end of the telescopic support rod 9 and rotate the telescopic support rod 9 back to its original position in the first slide groove 7. During this process, the protrusion of each cam 12 gradually disengages from the corresponding push block 15. At the same time, under the elastic force of the return spring 18, all sliders 16 drive the corresponding locking blocks 13 to disengage from the corresponding locking grooves 14 and slide back to the anti-corrosion plate 4. Finally, the anti-corrosion cover 1 can be removed.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
