Embodiment 1

[0053] At present, it is difficult for most inertia switches to realize the functions of adjustable threshold value, sensing inertial signals in multiple directions, and displaying working status. 2) The function of sensing inertial signals in multiple directions is realized, but the function of adjustable threshold value cannot be realized without replacing structural components; a planar multi-layer inertial switch (CN201810543393.9) realizes different overload threshold conditions However, the function of sensing inertial signals in multiple directions cannot be realized. A universal inertial switch with adjustable threshold and its closing method (CN202110389733.9) realizes the function of adjustable threshold and sensing multiple directions at the same time. The function of the inertial signal, but the working status of the inertial switch cannot be displayed.

[0054] In this embodiment, in view of the above problems, a passive inertial switch with self-displaying workin...

Abstract

The invention discloses a passive inertia switch capable of automatically displaying a working state, and relates to the technical field of inertia switches, the passive inertia switch specifically comprises a main body, a front cover and a rear cover, and the main body is a main functional part of the inertia switch; the front cover is provided with an observation port used for observing the working state of the inertia switch. The rear cover is an external interface of the inertia switch and is used for controlling the on-off of an external circuit; according to the invention, since the inertia switch is triggered by a pure mechanical structure, the inertia switch does not need external power supply; during use, the state of the guide head can be observed through the observation port, so that the working state of the inertia switch is obtained; on the premise that structural parts are not replaced, the trigger threshold value can be adjusted by adjusting the stress state of the spring; meanwhile, the guide head can slide out in any direction in a plane perpendicular to the axis, and inertial signals in any direction in one plane can be sensed.

Description

technical field [0001] The invention relates to the technical field of inertia switches, in particular to an inertia switch with a passive self-displaying working state. Background technique [0002] Inertial switch is a device that is sensitive to inertial signals. When it receives an inertial signal exceeding its threshold, it can realize the switch from opening to closing. It is also called threshold switch, acceleration switch or g-value switch. It is the current industrial field. It is an important device for sensing inertial signals in China; the existing inertia switch mainly adopts the structure of spring and mass block. When the inertia switch receives the inertial signal, the mass block overcomes the elastic force of the spring to move, and when the mass block moves to a certain distance, it contacts the electrode contact , so as to realize the switch from off to on state; the ideal inertia switch should have inertial signals that can sense any direction, adjustabl...
