The utility model, with reasonable structure and safer utilization, is suitable for using in mine or other areas of the similar environment conditions.
Description
Technical field
The utility model relates to a kind of explosion-proof magnetic normal open switch, the explosion-proof magnetic normal open switch of particularly a kind of isolated form.
Background technology
A kind of explosion-proof magnetic normal open switch is arranged in the prior art, be commonly called as tongue tube, structure as shown in Figure 1, moulding shell, two elasticity iron plates and two lead ends by one constitutes, two elasticity iron plates are placed in and are full of moulding in the shell enclosed cavity and the spacing of remaining valid of high pure nitrogen, and are connected and fixed on the lead end of moulding the shell two ends respectively.Moulding shell is the ABS plastic shell, and switch is completely enclosed within the nitrogen atmosphere, can not have the naked light flower to contact with extraneous, uses this type of switch in the colliery, can play the effect of firing and explosion prevention.But, if in the colliery carrying magnetic instrument is arranged, make it produce action near switch as coal shovel, chisel etc., then will cause security incident.
The utility model content
The purpose of this utility model is to provide a kind of isolated form explosion-proof magnetic normal open switch, a moving magnet button that itself carries, and extraneous magnetic thing can not can not caused accident because of misoperation near switch by isolation, so the product use is safer.
For achieving the above object, the utility model adopts following technical proposals:
The explosion-proof magnetic normal open switch of a kind of isolated form, comprise that one is moulded shell, two elasticity iron plates and two lead ends, two elasticity iron plates are placed in and are full of moulding in the shell enclosed cavity and the spacing of remaining valid of high pure nitrogen, and be connected and fixed on the lead end of moulding the shell two ends respectively, it is characterized in that the described shell of moulding is placed in the sealed plastic box with effective physical dimension, two lead ends connect the explosion-proof wiring post at sealed plastic box two ends respectively, two elasticity iron plates of a magnet button perpendicular alignmnet of fixed installation on the sealed plastic box.
The structure of above-mentioned magnet button is: mould lid with the sealed plastic box screw thread spins for one, revolve by screw thread and to join a plastics capsule, the end, settle a copper pressing spring to a magnet elastic bearing in the plastics capsule, magnet is fixedlyed connected with a button and is integral, button stretches out from the centre bore of moulding lid, is moulding lid and sealed plastic outer box wall pressing place and all is being lined with sealing ring with pressing place of plastics capsule openend.
Above-mentioned explosion-proof wiring post by copper sleeve and sealed plastic box two ends fixing seal in succession; Described sealed plastic box connects end cap by box body and constitutes, and there is sealing ring the junction.
Two above-mentioned elasticity iron plates are no remanent magnetism high strength elastic iron plate, are two bending shapes and the knee springing section parallels with the canned paragraph that is connected lead end; Magnet in the described magnet button is strong magnet, constitutes isolated form explosion-proof strong-magnetic normal open switch.
The utility model compared with prior art; have following conspicuous substantive distinguishing features and advantage: the utility model is placed in the explosion-proof magnetic normal open switch in the prior art in the sealed plastic box; and the magnet button of this explosion-proof magnetic normal open switch of starting is installed on sealed plastic box; then split the insulation blocking effect of closing; use safer; often play the moving magnet button, then use more convenient operation.The utility model is rational in infrastructure, and is easily manufactured, and operation easily is suitable for the mining area or promote the use of in the like environment zone.
