For solving the problems of the technologies described above, this electric system comprises the main cylinder and secondary cylinder that are locked together by locking member with loop on off test device, coaxially rotating shaft is fixed with in main cylinder, rotating shaft is set with rotating disk, main cylinder is provided with axially extended chute, rotating disk avris is installed with the directed slide block extending chute, rotating shaft outer end is hinged with some connecting rods successively by the hinge be arranged in parallel, the rotating shaft of hinge side or connecting rod being installed with when the rotating shaft of hinge both sides becomes coaxial with shaft swing or when rotating shaft becomes coaxial with connecting rod swing can by the flexure strip of the connecting rod of hinge opposite side or rotating shaft elastic clamping, rotating shaft between rotating disk and connecting rod is wound with wire, wire one end is electrically connected with rotating shaft, secondary cylinder one end is installed with nut, probe is fitted with in nut, the inner periphery of probe is provided with the thread segment with nut screw connection, in secondary cylinder, the battery and alarm that are connected in series with probe and wire are installed.
This electric system is that realized by tandem binary deformable contraction structure can test loop break-make with loop on off test device, and simple to operate, a people just can operate, and volume is little, lightweight, easy to carry, processing safety is high.
Tandem binary deformable contraction structure mainly refers to and includes serially connected couple structure and deformable contraction structure in this electric system with in the on off test device of loop.Wherein tandem couple structure mainly comprises main cylinder and secondary cylinder, and is arranged on the associated components in main cylinder and secondary cylinder.Binary just refers to main cylinder and secondary cylinder, and series connection not only refers to that main cylinder and secondary cylinder are linked together by wire, more refers to that the circuit in main cylinder and the circuit in secondary cylinder form series relationship.Specifically, be provided with rotating shaft in main cylinder, rotating shaft and main cylinder are coaxially arranged, and rotating shaft and wire one end link together.In secondary cylinder, probe is installed, battery and battery-powered alarm are also installed.In secondary cylinder, battery, alarm, probe and wire termination are serially connected.Again because in main cylinder, wire termination and rotating shaft are also serially connected.Therefore, through the connection of wire, the battery of the rotating shaft in main cylinder and secondary cylinder, alarm, probe constitute series relationship.When probe is contacted with rotating shaft outer end, whole tandem link just constitutes a power circuit, and now under the supply of battery, alarm will send alerting signal and point out, and also just proves to constitute a power circuit.Same, when when probe and rotating shaft outer termination are contacted connection circuit two ends, still can form a power circuit, alarm still can send alerting signal and point out.And when probe and rotating shaft outer termination are contacted dead circuit two ends, power circuit just cannot be formed, alarm also just cannot be reported to the police.Therefore, by the signal prompt of alarm, the on off operating mode of quick decision circuitry can be carried out.
Deformable contraction structure comprises two parts, and a part is the deformable contraction structure of main cylinder side, and another part is the deformable contraction structure of secondary cylinder side.Specifically, the deformable contraction structure of main cylinder side mainly comprises the rotating disk be sleeved in rotating shaft, and rotating disk not only can axis of rotation relatively, and can slide axially along rotating shaft.Main cylinder sidewall is provided with chute, and chute is axially arranged along main cylinder.Rotating disk edge is installed with directed slide block, and directed slide block coordinates with slide.When rotating disk slides axially along rotating shaft, directed slide block also slides in the same way along chute.Therefore, the effect of directed slide block and chute, is exactly directed to the diametrically opposed main cylinder of rotating disk, namely makes rotating disk slide axially relative to main cylinder and can not rotate.
