Abstract

The present invention relates to the technical field of water meters, and in particular, to a disassembly-proof water meter with an internal lock. The water meter at least comprises a water meter body, a fixing ring is installed on the outside of the water meter body, water pipes are connected to both sides of the fixing ring, shafts are symmetrically arranged on the surface of the fixing ring, lower connecting arms are installed on the surface of the shafts, a turntable is installed on the surface of the lower connecting arms, a lower cross arm is arranged at the bottom of the lower connecting arms, and a magnifying lens is arranged between the lower cross arms; an upper connecting arm, the upper connecting arm is fixedly connected to the shaft, an upper cross arm is installed on the top of the upper connecting arm, an upper baffle is connected between the upper cross arms, a connecting plate is arranged below the upper baffle, and the upper baffle and the connecting plate are connected by an upper spring. Through the magnifying lens, the reading on the surface of the water meter body is magnified and irradiated at multiple positions, and when not in use, the upper baffle and the connecting plate act, and the connecting plate will seal the display on the surface of the water meter body under the elastic force of the upper spring to achieve sealing and dustproof.
