Anti-falling structure for magnetic transmission assembly of diaphragm gas meter

Abstract

The utility model relates to the technical field of gas meter equipment, and discloses a film type gas meter magnetic transmission assembly anti-falling structure which comprises a first shell, a damping assembly is arranged on the periphery of the first shell, a telescopic rod is fixedly connected to the interior of the first shell, the telescopic end of the telescopic rod is fixedly connected with a movable plate, and the movable plate is fixedly connected with the damping assembly. And limiting blocks are fixedly connected to the left side and the right side of the movable plate correspondingly, clamping plates are slidably connected to the peripheries of the limiting blocks, magnetic transmission bodies abut against the opposite sides of the two clamping plates, the bottoms of the magnetic transmission bodies abut against the interior of the first shell, and the bottoms of the clamping plates abut against the interior of the first shell. According to the gas meter magnetic transmission assembly, the telescopic rod can drive the clamping plate to move, the clamping plate can fix the magnetic transmission body through movement, so that the magnetic transmission body is prevented from falling off, the accuracy of the gas meter is ensured, the rubber pad is fixed to the periphery of the first shell, the influence of external vibration on the magnetic transmission assembly can be reduced, and the stability of the gas meter magnetic transmission assembly is improved.
