A kind of operating mechanism of the reclosing circuit breaker that leaks electricity
Technical field
The present invention relates to breaker technical field, particularly a kind of operating mechanism of the reclosing circuit breaker that leaks electricity.
Background technology
The operating mechanism of electric leakage reclosing circuit breaker is when motor operation, and the motor rotary shaft radial load is uneven, and when the toggle of motor rotated, the radial load that produces was damaged motor.
Summary of the invention
The objective of the invention is: provide a kind of operating mechanism of the reclosing circuit breaker that leaks electricity, to overcome the existing defective that adopts the spring life low technical.
According to above-mentioned purpose, the technical solution adopted in the present invention is: a kind of operating mechanism of the reclosing circuit breaker that leaks electricity, comprise the handle and the motor that are installed on the body, 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.
Be provided with shell fragment between described connecting rod and the crank.
Described connecting rod is provided with hand push rod.
The rotating shaft of passing through of described motor is connected with ratchet, and described rotating shaft is provided with the oval plane, also is provided with the oval plane of matching with it on the described ratchet.
Be connected by circular hole between described crank and the 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 owing to being equipped with ratchet on the crank connecting link, and when motor operation, many pawl structures can guarantee radially equilibrium of forces of motor rotary shaft, avoids motor because of the radial load that toggle produces when rotating and damages motor;
2, the rotating shaft of the ratchet of structure of the present invention and motor is rotated simultaneously, and the crank of toggle is radially for rotating with the rotating shaft of motor, when not needing motor operation, and when adopting manual operation, ratchet does not rotate, this moment the axle on the rotating crank, ratchet can separate with ratchet, so that toggle can be smoothly towards a unidirectional reliable running.
3, more simple and reliable than existing from part complexity and processing technology.

Embodiment
In conjunction with Fig. 1-Fig. 6, operating mechanism structural representation for a kind of reclosing circuit breaker that leaks electricity, what adopt is the dual principle of ratchet and pawl arrangement and toggle, it comprises handle 2 and the motor 9 that is installed on the body 1, handle 2 is connected with motor 9 by connecting rod 3, it is characterized in that: described motor 9 is provided with ratchet 8, described connecting rod 3 is connected with ratchet 7 by crank 5, described ratchet is provided with 2, described ratchet 8 is meshed with described ratchet 7, be provided with shell fragment 6 between described connecting rod 3 and the crank 5, described connecting rod 3 is provided with hand push rod 4, and the rotating shaft of passing through of described motor 9 is connected with ratchet 8, and described rotating shaft is provided with the oval plane, also be provided with the oval plane of matching with it on the described ratchet 8, be connected by circular hole between described crank 5 and the ratchet 7.
Structure of the present invention is to utilize the rotation of motor 9 to rotate to drive ratchet 8 rotation rotations, then rotated to drive the rotation of ratchet 7 by the rotation of ratchet 8, drive crank 5 by ratchet 7 again and do the rotation round motion, connecting rod 3 is seesawed, operate the handle 2 of electric leakage reclosing circuit breaker, realize the various operation controls such as electric leakage reclosing circuit breaker divides, closes.
