Abstract
The invention discloses an operating mechanism of an electricity leakage reclosure circuit breaker, relating to the technical field of circuit breakers and overcoming the defects that the radial force of a motor rotating shaft of the existing electricity leakage reclosure circuit breaker is unbalanced to cause the damage of a motor. The operating mechanism comprises a handle and a motor which are arranged on a body, the handle is connected with the motor by a connecting rod, a ratchet wheel is arranged on the motor, the connecting rod is connected with a pawl through a crank, the ratchet wheel and the pawl are meshed, an elastic sheet is arranged between the connecting rod and the crank, and a manual push rod is arranged on the connecting rod; when the motor works, a multi-pawl structure can ensure the balance of radial force of the motor rotating shaft, thus avoiding the damage to the motor due to radial force generated in rotation of a crank connecting rod mechanism; when the motor is not needed to work, the ratchet wheel does not work when manual operation is adopted, the pawls and the ratchet wheel can be separated by rotating a shaft on the crank, so that the crank connecting rod mechanism can successfully run reliably towards one way.
Description
Technical field
The present invention relates to breaker technical field, particularly a kind of operating mechanism of electric leakage reclosure breaker.
Background technology
The operating mechanism of electric leakage reclosure breaker is when motor works, and motor rotary shaft radial load is uneven, and when the toggle of motor rotates, the radial load produced damages motor.
Summary of the invention
The object of the invention is: the operating mechanism that a kind of electric leakage reclosure breaker is provided, to overcome the defect of existing employing spring life low technical.
According to above-mentioned purpose, the technical solution adopted in the present invention is: a kind of operating mechanism of electric leakage reclosure breaker, comprise and be installed on handle on body and motor, handle is connected with motor by connecting rod, it is characterized in that: described motor is provided with ratchet, described connecting rod is connected with ratchet by crank, and described ratchet is meshed with described ratchet.
Shell fragment is provided with between described connecting rod and crank.
Described connecting rod is provided with hand push rod.
Being connected with ratchet by rotating shaft of described motor, described rotating shaft is provided with oval plane, described ratchet is also provided with the oval plane matched with it.
Described crank is connected by circular hole with between ratchet.
Described ratchet is provided with more than 1 or 1.
Compared with prior art, advantage of the present invention and beneficial effect are:
1, the present invention is due to crank connecting link being equipped with ratchet, and when motor works, many pawl structures can ensure the radial equilibrium of forces of motor rotary shaft, avoid motor because of the radial load produced when toggle rotates and damage motor;
2, the ratchet of structure of the present invention and the rotating shaft of motor are rotated simultaneously, and the crank of toggle is radial for rotate with the rotating shaft of motor, when not needing motor to work, and when adopting manual operation, ratchet does not rotate, axle now on rotating crank, ratchet can be separated with ratchet, makes toggle can smoothly towards a unidirectional reliable running.
3, from part complexity and processing technology more simple and reliable than existing.
