Description

Tooth-locking type level switch with adjustable rotation direction Technical Field The utility model relates to the technical field of level switches, in particular to a tooth-locking type level switch with an adjustable rotation direction. Background The tooth-locking type material level switch (also called a rotation-resisting type material level switch or a rotating blade type material level switch) is a mechanical contact type material level detection device and is mainly used for monitoring the material level of solid materials (such as powder, particles and block materials). The core principle is that whether the material reaches the set position is judged through the resistance change of the rotating blades. The miniature motor of the rotation-resisting switch is generally unidirectional rotation (such as clockwise), the blade is blocked by materials, the trigger signal is fixed in direction, but under the condition of facing multi-pipeline feeding, the rotation direction of the blade needs to be adjusted to adapt to the installation position (such as left side feeding or right side feeding), and if the miniature motor capable of bidirectionally rotating is installed, the production cost can be increased, and the market competition is not facilitated. Therefore, it is necessary to provide a rotary direction adjustable lock type level switch to solve the above problems. Disclosure of utility model The utility model aims to provide a rotary direction adjustable tooth-locking type level switch, which solves the problem that in the prior art, under the condition of multi-pipeline feeding, the rotation direction of a blade needs to be adjusted to adapt to the installation position by matching a shell and a bidirectional rotation mechanism.
