The mechanical tripping mechanism comprises a support, a tripping cam, a tripping plate, a rotating wheel and a wiring rocker. The tripping cam is rotatably arranged at the top of the support. The tripping cam is connected with a rotary knob. The tripping plate is arranged at one side of the tripping cam and swings left and right, and the tripping plate resets through a first torsional spring. The swing end of the tripping plate is abutted against the cam surface of the tripping cam under torsional force of the first torsional spring. The rotating wheel is rotatably arranged in the support and resets through a second torsional spring. The rotating wheel is equipped with a locking protruding edge.

Technical field

The utility model relates to a kind of earth leakage protective socket, particularly a kind of mechanical trip mechanism for earth leakage protective socket.

Background technology

The defencive function of automatic shutdown circuit when earth leakage protective socket has situations such as occurring electric leakage overload in circuit, and this function is to drive realization by the magnetictrip in earth leakage protective socket.The situation that cannot cut off circuit in order to prevent in the time that magnetictrip lost efficacy occurs, and is also provided with special manual mechanical tripping mechanism on earth leakage protective socket now, and this manual mechanical tripping mechanism can remove to cut off by force circuit with hand.At present, manual mechanical tripping mechanism adopts the structure of push button, in the time that pressing, circuit is connected by button, in the time that button is upspring by circuitry cuts, but the mechanical trip mechanism of this button type structure is easily because button is very easily touched and produced misoperation by foreign object, and button in use exists larger wearing and tearing, cause useful life not high.

Summary of the invention

For the deficiencies in the prior art, problem to be solved in the utility model is to provide a kind of action accurately and reliably, be difficult for producing misoperation, and useful life the higher mechanical trip mechanism for earth leakage protective socket.

For this reason, the utility model is realized in the following way:

A kind of mechanical trip mechanism for earth leakage protective socket, it is characterized in that: comprise support, deflecting cam, dropout plate, moving runner and wiring seesaw, described deflecting cam is arranged on a top of the trellis rotationally, deflecting cam is connected with knob, described dropout plate swings and arranges and reset by the first torsion spring in a side of deflecting cam, under the twisting force of the first torsion spring, the swinging end of dropout plate is against the cam surface of living deflecting cam, described moving runner is arranged on rotationally internal stent and resets by the second torsion spring, moving runner is provided with locking convex edge, dropout plate is provided with locking fenestra, when mechanical trip mechanism is in the front state of threading off, locking convex edge fastener is lived locking fenestra, described wiring seesaw swings up and down setting below moving runner, wiring seesaw is connected by connecting rod with moving runner, described moving runner is provided with driving lever and reaches deflecting cam lower end, deflecting cam lower end is provided with the shifting block corresponding with driving lever.

In the utility model; by the rotation action of initial knob; then finally change the wobbling action of wiring seesaw into through the action of deflecting cam, dropout plate and moving runner; realize the contact of wiring seesaw and electrical contact in earth leakage protective socket or separate, thereby realizing switching on or off of circuit.This mechanical trip mechanism that realizes hand tripping and hand-reset action by knob, has the following advantages: 1. reliable in action is accurate, can malfunction; 2. mechanism wear is little, long service life; 3. thread off in time, be swift in motion; 4. mechanical structure, Non-energy-consumption.

The utlity model has automatic tripping function, the technical scheme of employing is: on described dropout plate, be fixedly connected with dropout iron core, the activity of described dropout iron core is located in the magnetictrip in earth leakage protective socket.Automatically the implementation procedure of tripping function is, in the time that reaching certain condition, sends electric wiring signal, allow dropout iron core produce rectilinear motion, pull dropout plate to swing, in the time that dropout plate is rocked to it and is not enough to hook moving runner, moving runner rotates under the effect of the second torsion spring, drives wiring seesaw upwards to swing by the effect of connecting rod simultaneously, completes the action of threading off.
