Explosive-proof magnetic-induction operator and magnetic operating pen

Abstract

This is an explosion-proof magnetic induction device and magnetic operation pen. The device includes an explosion partition box installed with electric apparatus treatment facility which includes a magnetic induction keyboard. The keyboard is installed in the partition box with a mark on corresponding position on the outside of the box. The pen is of a magnetic element on it.

Description

Explosion-proof magnetic induction operating device and magnetic operating pen 1. Technical field The invention relates to the technical field of explosion-proof operating devices in explosive environments, and relates to an explosion-proof magnetic induction operating device and a magnetic operating pen. 2. Background technology At present, most explosion-proof smart instruments use buttons and switches with mechanical movement structures. The operation buttons and handles of buttons and switches of this type must be placed outside the explosion-proof box to operate the buttons and handles. At the same time, for explosion-proof The smart instrument system requires more buttons and switches to form a matrix or a coded keyboard. It is necessary to open holes in the flameproof instrument box and install the buttons and switches. Such buttons and switches are often large in size. With such a structure, Whether it is the airtight treatment of the explosion-proof box or the ins...

Problems solved by technology

At present, most explosion-proof smart instruments use buttons and switches with mechanical movement structures. The operation buttons and handles of buttons and switches of this type must be placed outside the explosion-proof box to operate the buttons and handles. At the same time, for explosion-proof The smart instrument system requires more buttons and switches to form a matrix or a coded keyboard. It is necessary to open holes in the flameproof instrument box and install the buttons and switches. Such buttons and switches are often large in size. With such a structure, Whether it is the airtight treatment of the explosion-proof box or the installation in a limited-volume explosion-proof instrument, there are great difficulties. The most important thing is that this structure may affect the explosion-proof performance of the equipment, and reduce the Explosion-proof performance index of explosion-proof equipment

Due to the limitation of the use environment, the material of the explosion-proof box is mostly cast aluminum or stainless steel, and the thickness of the box material is 15mm to 30mm, and the explosion-proof equipment does not allow holes to be installed on the box to install buttons and switches
