Description

Non-contact instruction button for coal mine Technical Field The utility model particularly relates to the technical field of buttons, in particular to a non-contact instruction button for a coal mine. Background At present, the electric operation is popular in underground coal mines, but because the electric contacts are easy to generate sparks and extremely easy to cause deflagration accidents in the environment filled with gas, underground electric equipment can go into the well only by coal safety certification, and an electric command switch is a button operated by a person, the button is pressed by hands, and a manual command is transmitted to a control system through the contacts of the button, so that the action of manual control equipment is completed. Disclosure of utility model The utility model aims to provide a non-contact instruction button for a coal mine, which is characterized in that in the using process, no contact is arranged in the non-contact instruction button, only one small permanent magnet moves up and down along with the pressing of a key, when the key is pressed down, a push rod moves down along with the key, a permanent magnet positioned at the bottom of the push rod moves to the lowest end, the metal reed inside a magnetic induction switch is magnetized by the enhancement of a magnetic field, the reed is magnetized and closed by opposite attraction, a circuit is conducted, the opening process is completed, and similarly, when the key is released, the permanent magnet is far away, the magnetic field is weakened, the reed is demagnetized and is reset by the elasticity of a spring, and the circuit is disconnected, so that the technical problems in the background technology are solved. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a non-contact instruction button that colliery was used in pit, includes the installation panel, the bottom is installed on the top of installation panel, and the top fixed mounting of bottom has the casing, the inside center department movable mounting of casing has the push rod, and the top fixedly connected with button of push rod, the bottom central point of push rod puts and has the permanent magnet through glue connection. As a further technical scheme of the utility model, a lower seal is arranged between the bottom cover and the shell, and an upper seal is arranged between the opening at the top end of the shell and the push rod. As a further technical scheme of the utility model, the bottom of the installation panel is provided with the magnetic induction switch, and the magnetic induction switch is positioned right below the permanent magnet. As a further technical scheme of the utility model, the magnetic induction switch is of a reed pipe structure, is of a closed structure with two magnetizable metal reeds inside, and is internally packaged with inert gas. As a further technical scheme of the utility model, the bottom of the push rod is of a circular ring structure, the inner wall of the bottom of the push rod is fixedly connected with the permanent magnet, the push rod is of a cross-shaped structure, and limiting blocks are integrally formed on two sides of the push rod. As a further technical scheme of the utility model, a spring is arranged between the key and the shell, and the spring is sleeved on the outer side of the push rod. As a further technical scheme of the utility model, a spring is arranged between the inner wall of the shell and the limiting block. Compared with the prior art, the utility model has the beneficial effects that: In the using process, the utility model has no contact inside, only one small permanent magnet moves up and down along with the pressing of the key, when the key is pressed, the push rod moves downwards along with the key, the permanent magnet positioned at the bottom of the push rod moves to the lowest end, the enhancement of the magnetic field magnetizes the metal reed inside the magnetic induction switch, the reed is magnetized to be closed due to opposite attraction, the circuit is conducted, the opening process is completed, and similarly, when the key is released, the permanent magnet is far away, the magnetic field weakens, the reed demagnetizes, and the circuit is disconnected by virtue of elastic reset of the spring.
