Problems solved by technology
The false start of production and processing equipment is mostly caused by the accidental touch of its power on and off switch.
That is, when the production and processing equipment should be in the state of power failure and outage (at this time, workers usually overhaul and maintain the production and processing equipment), its power on and off switch is accidentally touched by other workers or objects, which makes the power on and off. The power-off switch is pressed and the operation is suddenly started, which in turn injures the workers who are performing inspection and maintenance for production and processing
[0003] Moreover, if the production and processing equipment is in operation, it is accidentally touched and the power is cut off. On the one hand, it is easy to produce defective products; etc., seriously affecting production efficiency
In addition, the sudden power failure of production and processing equipment may also cause safety problems and lead to accidents

Embodiment Construction
[0040] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0041] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

The present invention relates to a safety switch that realizes power-on or power-off through two intermittent rotations, comprising: a fixed base, an electric control base, a transmission mechanism, a switch action mechanism and a withdrawal mechanism, and the fixed base is set on the On the electric control base; the transmission mechanism is connected with the switch action mechanism, and the switch action mechanism is connected with the withdrawal mechanism. The transmission mechanism includes: an active connecting rod, a passive sleeve rod, a transmission torsion spring and a transmission turntable. The switch action mechanism includes: a transmission drum, a connecting roller, a rod contact and a first return spring. The safety switch disclosed by the present invention realizes power-on or power-off through two intermittent rotations, which can effectively avoid wrong power-on or power-off caused by mistaken touch; provide effective personal safety protection for production workers and prevent safety accidents ; At the same time, improve the production efficiency of the enterprise and the yield rate of the product.
Description
technical field [0001] The invention relates to the technical field of a safety switch, in particular to a safety switch which realizes power-on or power-off through two intermittent rotations. Background technique [0002] In the field of industrial production technology, it often happens that production and processing equipment accidentally injures workers. However, the accidental injury of workers by production and processing equipment is mainly caused by two aspects. On the one hand, it is caused by improper operation of workers, and on the other hand, it is caused by false start of production and processing equipment. The false start of the processing equipment is mostly caused by the accidental touch of its power on and off switch. That is, when the production and processing equipment should be in the state of power failure and outage (at this time, workers usually overhaul and maintain the production and processing equipment), its power on and off switch is accidenta...
