Industrial display type pressure transmitter with anti-loosening mechanism

The utility model discloses an industrial display type pressure transmitter with an anti-loosening mechanism, which comprises a body and a base, and further comprises a first fixed bulge, a second fixed bulge, a third fixed bulge and a fourth fixed bulge, a threaded rod; the second fixing protrusion is located on the upper end face of the base. The threaded hole is located in the upper end face of the second fixing protrusion. And the anti-loosening mechanism is located between the first fixing protrusion and the second fixing protrusion, and the anti-loosening mechanism is used for preventing the threaded rod from loosening due to vibration deflection. According to the utility model, after the threaded hole and the threaded rod are screwed tightly, the limiting bulge is positioned in the limiting hole by pressing the transmission rod, at the moment, under the action of the limiting spring, the limiting bulge and the limiting hole are mutually clamped, and the limiting bulge cannot fall off from the limiting
