Abstract
The utility model relates to a waterproof foot switch device which is characterized in that the waterproof foot switch device is provided with a casing body made of nonmagnetic material. The casing body is composed of a base seat and an upper cover, wherein the base seat is articulated with the upper cover, a switch main body adopting a reed switch is fixed on the base seat, the reed switch is electrically connected with a power control line, a compressed spring is arranged at the middle part of the base seat and the upper cover, and a magnet box filled with magnetic material is arranged on the upper cover and at the position corresponding to the switch main body. Any mechanical connection is not required to be adopted between the foot-controlled transmission of the utility model and an electrical contact, and the waterproof foot switch device has the advantages that the structure is reliable, the sealing property is excellent, and the waterproof performance is greatly improved.
Description
Technical field
The utility model relates to a kind of switch, especially relates to a kind of water proof type control switch of controlling realized by the magnetic force induction tongue tube.
Background technology
At present, be used for places such as Medical Devices, mechanical industry, textile mills and underwater work, be used to control electric waterproof Foot-controlled switch device, mostly adopt pedal driven, the conversion that makes electric contact in its switch case carry out through and off by the drive link that is connected with pedal realizes the break-make of electric signal.The waterproof Foot-controlled switch device of this structure owing to be in transmission connection between drive link and the switch case, certainly exists the gap therebetween, and it is not fine that this gap often makes the performance of its waterproof, thereby reduces the performance of its explosion-proof dustproof and waterproof.Long-term work in addition, the sealing surface abrasion, rubber takes place aging: as can not running check, will have an accident.Bring serious loss for country and personnel.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, thereby develops a kind of waterproof Foot-controlled switch device that adopts the magnetic force induction dry-reed.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of waterproof Foot-controlled switch device, it is characterized in that: have a housing that adopts non-magnet material to make, described housing is made up of base and loam cake, described base adopts hinge to be connected with an end of loam cake, and the simplest method of attachment is to adopt pin to connect; On described base, be fixed with the switch main body that adopts tongue tube, tongue tube can be one or many, described tongue tube is electrically connected with power control line, middle part at described base and loam cake is equipped with stage clip, on described, cover, with the corresponding position of switch main body the magnet case that magnetic material is housed is set, the quantity of magnetic can be corresponding with the tongue tube number.Described non-magnet material can be plastics, aluminium, copper material etc.
The utility model since the magnet in the loam cake near or away from tongue tube, so the variation of through and off also takes place tongue tube, for the open type tongue tube, if initial loam cake is in nature when unclamping, tongue tube is in against magnetic state, then tongue tube is in off-state; When loam cake was operated, because tongue tube is in paramagnetic state, then tongue tube was in conducting state.Normally closed dry reed pipe is then just opposite therewith, thereby realizes the break-make control to electric signal.
Owing to adopt such scheme, need not any mechanical connection between foot control transmission and the electric contact, its reliable in structure, because no any joint gap, thereby sealing property is fabulous, and the performance of its waterproof is improved greatly.
Description of drawings
Accompanying drawing 1 is an exploded view of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Tongue tube is fixed in the switch main body 2 of seal box with the epoxy resin pouring, and will be reserved with the pin two ends of the wire bonds of certain-length at tongue tube, and the lead of switch main body 2 passes the line outlet of base 1, and switch main body 2 is fixed on the base 1.Magnet 6 is fixed to the corresponding site of loam cake 7 inside and switch main body, and spring 3 is placed on the base 1, the loam cake 7 that closes then, and fill in latch 4.
During use, when riding loam cake 7, the magnet in the loam cake 7 inner magnet boxes 6 is near switch main body 2, the reed switch contact adhesive in the switch main body 2; When pin unclamped, the magnet in the magnet case 6 in the loam cake 7 was away from the tongue tube in the switch main body 2, and reed switch contact discharges, thereby reached the purpose of control electric signal break-make.Since there be not mechanical the connection between the magnet in the loam cake 7 and the switch main body 2, can make switch main body that good sealing is arranged, thus make Foot-controlled switch reach extraordinary sealing property.
