Abstract
The utility model discloses an elevator flat layer monostable magnetic switch, including PCB board, glass pipe, inert gas, dry reed and wire, the glass pipe is installed to PCB board top, and the dry reed is all inserted and installed at the glass pipe both ends, and two the end initial state that dry reed stretches into the glass pipe inner chamber is not contacted, the glass pipe inner chamber is filled with inert gas, and the wire is drawn forth to PCB board one side, the wire branches into two and corresponds a dry reed of connection respectively; the utility model discloses, switch stability is good, and overall structure is favorable to accomplishing shockproof, dustproof and waterproof.
Description
Technical Field
The utility model relates to a magnetic switch technical field specifically is an elevator flat bed monostable magnetic switch.
Background
The magnetic switch is divided into a single-pole single-throw (SPST) and a single-pole double-throw (SPDT) according to the output type, and is divided into a high alarm (anti-overflow) and a low alarm (anti-idle running) according to the purpose, but the existing magnetic switch has poor stability, and the whole structure is not beneficial to shock resistance, dust prevention and water prevention; in view of these drawbacks, it is necessary to design a monostable magnetic switch for elevator leveling.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an elevator flat bed monostable magnetic switch, the switch stability is good, and overall structure is favorable to accomplishing shockproof, dustproof and waterproof.
The purpose of the utility model can be realized by the following technical scheme:
the utility model provides an elevator flat bed monostable magnetic switch, includes PCB board, glass pipe, inert gas, dry reed and wire, the glass pipe is installed to PCB board top, just the dry reed is all inserted at the glass pipe both ends and is installed, two the end initial condition that the dry reed stretches into the glass pipe inner chamber does not contact down, the glass pipe inner chamber is filled with inert gas, just the wire is drawn forth to PCB board one side, the wire branch becomes two and corresponds a dry reed of connection respectively.
The utility model has the advantages that: put magnet at glass pipe one end, when magnet from the top down moves, two dry reed contacts in the glass pipe are closed, and the glass pipe switches on, and the glass pipe of this moment is equal to a lead-through wire, and this structure is put into putting into the copper pipe wholly, and the inside watering epoxy prevents to damage monostable magnetic switch because of vibrating, then seals the copper pipe, is favorable to taking precautions against earthquakes, dustproof and waterproof, and this structure switch stability is good simultaneously, and overall structure is favorable to accomplishing to take precautions against earthquakes, dustproof and waterproof.
Drawings
In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.
FIG. 1 is a general plan view of the present invention;
in the figure: 1. a PCB board; 2. a glass tube; 3. an inert gas; 4. dry reed pieces; 5. and (4) conducting wires.
Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in figure 1, an elevator flat layer monostable magnetic switch, including PCB board 1, glass pipe 2, inert gas 3, dry reed 4 and wire 5, glass pipe 2 is installed at PCB board 1 top, and glass pipe 2 both ends are all inserted and are installed dry reed 4, two dry reed 4 stretch into and do not contact under the end initial condition of 2 inner chambers of glass pipe, 2 inner chambers of glass pipe are filled with inert gas 3, and PCB board 1 one side is drawn forth wire 5, wire 5 branches become two and correspond respectively and connect a dry reed 4.
The utility model discloses a theory of operation: put magnet at 2 one ends of glass pipe, when magnet from the top down moves, two dry reed 4 contacts closures in the glass pipe 2, glass pipe 2 switches on, glass pipe 2 this moment is equal to a lead-through wire, this structure, put into the copper pipe wholly, the inside watering epoxy prevents to damage monostable magnetic switch because of vibrating, then it is sealed with the copper pipe, be favorable to taking precautions against earthquakes, dustproof and waterproof, this structure switch stability is good simultaneously, overall structure is favorable to accomplishing to take precautions against earthquakes, dustproof and waterproof.
The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention. The preferred embodiments are not intended to be exhaustive or to limit the invention to the precise embodiments disclosed. Obviously, many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications, to thereby enable others skilled in the art to best understand the invention for and utilize the invention. The present invention is limited only by the claims and their full scope and equivalents.
