Abstract

The invention relates to a threshold-adjustable universal inertial switch and a closing method thereof, which belong to the technical field of inertial switches and solve the problem that the prior art cannot simultaneously realize the adjustment of the switch threshold and the induction of inertial signals in multiple directions. Including universal transmission structure, guide head, positioner, switch trigger and threshold adjustment mechanism; one end of the guide head is connected to the universal transmission structure, and the other end is buckled with the positioner; the positioner is fixedly connected to the switch trigger and acts synchronously; The locator provides the pressing force to buckle with the guide head through the threshold adjustment mechanism; when the impact force received by the inertial switch is greater than the pressing force provided by the threshold adjustment mechanism, the positioner and the guide head are released, and the pressing force provided by the threshold adjustment mechanism Enables the switch trigger to trigger the inertial switch to close.

Description

technical field [0001] The invention relates to the technical field of inertial switches, in particular to a universal inertial switch with adjustable threshold and a closing method thereof. Background technique [0002] Inertial switch is a device sensitive to inertial signals. When the inertial signal exceeds its threshold, it can realize the switching function from opening to closing. It is also called threshold switch, acceleration switch or g-value switch. It is the current industrial field. An important device for sensing inertial signals in the medium. The existing inertial switch mainly adopts the structure of spring and mass block. When the inertial switch receives the inertial signal, the mass block overcomes the elastic force of the spring and moves. Switching of the conduction state. An ideal inertial switch should have the ability to sense inertial signals in any direction, adjustable threshold, self-locking function, high reliability and stability. [0003] ...
