Description
Technical field
The utility model is related to a kind of switch, the antidetonation heat-resistance type door machine bistable switch that more particularly to a kind of band LED is indicated.
Background technology
In elevator door machine system, elevator cage level position detecting system, bistable switch can be all used.The operating door open limit of elevator door-motor, closes the door spacing, opens the door and slows down, and closes the door and slows down this series of shift position by bistable switch control.
Existing door machine bistable switch, switch Stable structure unstable properties, shock resistance is poor, low temperature environment is high using fault rate, because elevator door-motor bistable switch is in the bad and not easy to install position of line-of-sight circumstances in actual switch use environment, when door machine control system failure, it is impossible to intuitively judge the working condition of bistable switch, need under switch dismounting again with supplementary instrument to be judged, after-sales service so follow-up to elevator is made troubles.
Utility model content
Technical problem to be solved in the utility model is that there is provided the antidetonation heat-resistance type door machine bistable switch that a kind of new band LED is indicated in view of the shortcomings of the prior art.
To achieve these goals, the measure that the utility model is taken：
The antidetonation heat-resistance type door machine bistable switch that a kind of band LED is indicated, including switch housing base, the reed switch of control turning circuit is installed in described switch housing base, realizes that stable state protects the magnetic sheet and against shock rubber blanket of magnetic, switch housing base one end is provided with the copper connecting pole being connected with reed switch, switch housing base top is provided with switch housing cover plate, the PCB for being provided with LED light is surveyed in switch housing cover plate, LED light is reached outside switch housing cover plate；
It is stamped with offering screw thread in wiring hole and wire fixing hole, wire fixing hole on described copper connecting pole；
Described switch housing base side is molded with least two mounting holes, and the section of mounting hole is the rectangle that a two ends are camber line；
Described against shock rubber blanket, at reed switch two ends, plays antihunt action using two flexible rubber cushion covers；
PCB band LED light function in described switch housing cover plate.
LED light is installed in described PCB；
Described core component reed switch and two magnetic sheets composition switch motion mechanism on switch housing base.
The beneficial effects of the utility model：Practicality, can pilot switch at any time working condition, judge whether switch abnormal, and the anti-vibration resistance of switch is strong；The design for being isolated reed switch with housing using flexible rubber pad, the influence by the percussion vibrations thought when reducing general transportability vibrations or switch installation to internal reed switch；Switch temperature tolerance good, using double magnetic sheet structures, active area of the magnetic sheet to reed switch can be increased, under the change of relatively low outdoor environment temperature, switch is normally kept work, good stability.
Brief description of the drawings
Fig. 1, structural representation of the present utility model.
Embodiment
The antidetonation heat-resistance type door machine bistable switch that a kind of band LED is indicated, including switch housing base 1, the reed switch 2 of control turning circuit is installed in described switch housing base 1, realizes that stable state protects the magnetic sheet 3 and against shock rubber blanket 4 of magnetic, the one end of switch housing base 1 is provided with the copper connecting pole 5 being connected with reed switch 2, the top of switch housing base 1 is provided with switch housing cover plate 6, the PCB 7 for being provided with LED light is surveyed in switch housing cover plate 6, LED light is reached outside switch housing cover plate 6.
It is stamped with offering screw thread in wiring hole and wire fixing hole, wire fixing hole on described copper connecting pole 5.
The described side of switch housing base 1 is molded with least two mounting holes, and the section of mounting hole is the rectangle that a two ends are camber line.
Described against shock rubber blanket 4, at the two ends of reed switch 2, plays antihunt action using two flexible rubber cushion covers.
PCB 7 in described switch housing cover plate 6 is with LED light function.
The PCB 7 for being provided with LED light is surveyed in described switch housing cover plate 6, on off state display effect is played.
Described reed switch 2 and two magnetic sheets 3 composition switch motion mechanism on switch housing base 7
Described against shock rubber blanket 4, at the two ends of reed switch 2, plays antihunt action using two flexible rubber cushion covers.
In the Elevator Door Control System of test position is needed, install the utility model, when elevator door movement, elevator drive magnet is to when being moved to above the utility model, the utility model closure conducting, signal is realized to open the door and open the door to the Frequency Converter Control motor work in control system to slow down, now the utility model is closure state, LED light is lighted, and keeps this state, when drive magnet is reverses through the utility model, the utility model will be switched off, now LED light will be extinguished, and the display of two kinds of working conditions is very directly perceived, realizes the purpose of this utility model.
The utility model product is had the special feature that：1. the stable state with very strong shock resistance keeps having two independent flexible rubber pads inside function, the utility model, it easily will be isolated installation with switch housing base 1 by the reed switch 2 of vibration influence, reduce the conduction of external force, reach shock-absorbing function；2. using the structure of two magnetic sheets 3, active area of the magnetic sheet 3 to reed switch 2 can be increased, under the change of relatively low outdoor environment temperature, the utility model is normally kept work, good stability；3. with intuitively working condition detection function, LED light is shown, in addition, LED light is in series with protection circuit.
