Description

Pressure transmitter shell Technical Field The utility model relates to the field of pressure transmitter shells, in particular to a pressure transmitter shell. Background Pressure transmitters are devices for measuring the pressure of a medium such as liquid, gas or steam and converting the pressure into a standard signal for output, are widely used in industrial automation control systems for monitoring and adjusting the pressure in the systems to ensure the safe and stable operation of the devices and processes, and generally adopt pressure sensors, signal processing and output modules for pressure detection and signal transmission, and pressure transmitter shells are used for protecting electronic elements in the pressure transmitters. The back lid of current pressure transmitter casing one side passes through the screw thread and is connected with the casing, needs the user to rotate back lid many times, then tightens with force and just can accomplish the fixed to the back lid, but screw thread connection's back lid is comparatively troublesome when installing and dismantle. Disclosure of utility model Accordingly, it is an object of the present utility model to provide a pressure transmitter housing that solves the above-mentioned problems of the prior art. In order to achieve the purpose, the pressure transmitter shell comprises a shell body, wherein one side of the shell body is provided with a mounting hole, the inner wall of the mounting hole is movably provided with a convex ring, the end part of the convex ring is fixedly provided with a rear cover, the outer wall of the convex ring is provided with an entering groove, the outer wall of the convex ring is provided with a transverse groove, the outer wall of the convex ring is provided with an arc-shaped groove, the entering groove, the transverse groove and the arc-shaped groove are connected, and the inner wall of the mounting hole is fixedly provided with a plurality of groups of limiting blocks.
