Abstract
A novel pneumatic electric knife switch particularly relates to the technical field of electrical control switches. One side of a knife body (1) is provided with a cylinder mounting box (2), the inside of the cylinder mounting box (2) is equipped with a two-position three-way cylinder controller (8), the middle of the knife body (1) is of a funnel groove structure, the two outer side walls of the funnel groove are respectively provided with a conductive binding post (3), the bottom of the funnel groove is provided with a power supply binding post (4), a knife blade (5) is movably clamped to the power supply binding post (4), the tail of the knife blade (5) is provided with a movable groove (6), and an insulating cylinder telescopic rod (7) is movably clamped into the movable groove (6). Work of a pneumatic rod replaces manual operation, the production cost is reduced, and the problem that electric arc generated by direct operation harms an operator is avoided.
Description
Technical field
The utility model relates to electric controling switch technical field, is specifically related to a kind of novel pneumatic Electric knife switch switch.
Background technology
The disconnecting link one of lighting industrial, used in everyday is being all the compositions such as porcelain seat, blade, tool rest and Bakelite Cover, this traditional Electric knife switch can only be applicable to the break-make control of low-voltage, and in low pressure situation, also easily there is security incident, traditional Electric knife switch is not suitable for the use under high voltage in addition, because under high-voltage state, between plug-in strip blade and binding post, can produce electric arc, electric arc can puncture operator and cause death, danger very.
Summary of the invention
The purpose of this utility model is to provide a kind of novel pneumatic Electric knife switch switch, and it is simple in structure, adopts the work of air-leg to replace manual operation, has reduced cost of manufacture, and avoids the electric arc injury operator's of direct control generation problem.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises disconnecting link body 1, cylinder install bin 2, conductive connector 3, power-line terminal 4, plug-in strip blade 5, loose slot 6, insulation Telescopic-cylinder bar 7, two-position three way cylinder controller 8, one side of described disconnecting link body 1 is provided with cylinder install bin 2, the inside of cylinder install bin 2 is provided with two-position three way cylinder controller 8, the centre of described disconnecting link body 1 is funnel trough structure, two lateral walls of funnel trough are provided with conductive connector 3, the bottom of funnel trough is provided with power-line terminal 4, on power-line terminal 4, active card is connected to plug-in strip blade 5, the afterbody of plug-in strip blade 5 is provided with loose slot 6, the interior activity clamping insulation of loose slot 6 Telescopic-cylinder bar 7.
The utility model operation principle: the change of the inlet end gas circuit by air-operated solenoid valve, realize the telescopic action of insulation Telescopic-cylinder bar, thereby drive plug-in strip blade to carry out break-make control, replace traditional manual operations by the air inlet of conversion air inlet pipe, more safe and reliable.
The utlity model has following beneficial effect: it is simple in structure, adopt the work of air-leg to replace manual operation, reduced cost of manufacture, and avoid the electric arc injury operator's of direct control generation problem.
Accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
Embodiment:
Referring to Fig. 1, this embodiment is by the following technical solutions: it comprises disconnecting link body 1, cylinder install bin 2, conductive connector 3, power-line terminal 4, plug-in strip blade 5, loose slot 6, insulation Telescopic-cylinder bar 7, two-position three way cylinder controller 8, one side of described disconnecting link body 1 is provided with cylinder install bin 2, the inside of cylinder install bin 2 is provided with two-position three way cylinder controller 8, the centre of described disconnecting link body 1 is funnel trough structure, two lateral walls of funnel trough are provided with conductive connector 3, the bottom of funnel trough is provided with power-line terminal 4, on power-line terminal 4, active card is connected to plug-in strip blade 5, the afterbody of plug-in strip blade 5 is provided with loose slot 6, the interior activity clamping insulation of loose slot 6 Telescopic-cylinder bar 7.
This embodiment operation principle: the change of the inlet end gas circuit by air-operated solenoid valve, realize the telescopic action of insulation Telescopic-cylinder bar, thereby drive plug-in strip blade to carry out break-make control, replace traditional manual operations by the air inlet of conversion air inlet pipe, more safe and reliable.
This embodiment has following beneficial effect: it is simple in structure, adopts the work of air-leg to replace manual operation, has reduced cost of manufacture, and avoids the electric arc injury operator's of direct control generation problem.
