Embodiment
In order to make technical problem solved by the invention, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
A kind of automatic closing circuit breaker as Figure 1-Figure 11 comprises motor 1, first gear 2, conducting wheel 3, spring 4, second gear 5, handle 6 and axle 7; Motor 1 obtains enabling signal, electric machine rotation, motor 1 rotates drive first gear 2 and rotates, first gear 2 is engaged with conducting wheel 3 by the gear boss 21 of the first gear centre, conducting wheel 3 is driven to rotate, the conducting wheel gear teeth 31 coordinate with the projection 8 of shell side, conducting wheel 3 moves axially away from shell by axle 7, conducting wheel 3 moves axially, make the stressed generation deformation of spring 4, spring produces deformation power, and deformation power is less than the frictional force of the first gear 2 and the conducting wheel gear teeth 31 in motion, and conducting wheel can not set back because of the deformation force of spring.Conducting wheel 3 is moved axially by axle 7, make the second gear recesses 51 engage with the conducting wheel gear teeth 31 of conducting wheel simultaneously, the second gear 5 is driven to rotate, second gear 5 rotates, handle 6 by with the engaging of the second gear 5, the second gear 5 is with fixed handle 6 to move, and makes handle 6 reach closed position, switch close and, make it circuit breaker and realize closing function.
Motor 1 obtains stop signal, motor 1 stops operating, first gear 2 stops operating, conducting wheel 3 second gear 5 all stops operating, and the first gear 2 reduces with the frictional force of conducting wheel 3, and in motion, spring 4 distortion can be restored, promote conducting wheel 3 to be moved axially to the direction near shell by axle 7 simultaneously, conducting wheel 3 resets, and the conducting wheel gear teeth 31 separate with the second gear 5 simultaneously, and handle 6 reaches and can cut off position.
The motor shaft portion of motor 1 is connected with motor gear, realize being meshed with the first gear 2, when motor 1 receives the signal of telecommunication, rotate drive first gear 2 to rotate, there is arc boss at first gear 2 center, as gear boss, axle 7 there is the conducting wheel 3 be meshed with gear boss, so the first gear 2 drives conducting wheel 3 to rotate, the end face of the conducting wheel gear teeth 31 is a polyhedron, and conducting wheel 3 can move axially, the end face of the conducting wheel gear teeth 31, at the boss that casing has the end face of the conducting wheel gear teeth 31 corresponding, as casing boss, when conducting wheel 3 rotates, because the Polyhedral design of conducting wheel 3 end face matches with casing boss, conducting wheel 3 is moved to the direction away from casing, namely conducting wheel 3 moves to the second gear 5 direction, and engage with the second gear 5, conducting wheel 3 has been provided with conducting wheel boss towards the face of the second gear 5, second gear 5 core has the groove corresponding with conducting wheel boss, second gear 5 to move axially, so conducting wheel 3 drives the second gear 5 to rotate, second gear 5 drives switch knob 6 to move, play closed object.Spring 4 is had between conducting wheel 3 and the second gear 5, when motor 1 rotates, the first gear 2 is driven to rotate, first gear 2 drives conducting wheel 3 to rotate, conducting wheel 3 coordinates with the bossing of casing makes conducting wheel 3 move axially to the direction away from casing, and now spring 4 is out of shape stressed, but because motor 1 rotates, the frictional force between conducting wheel 3 and the first gear 2 is increased, make frictional force be greater than the deformation force of spring 4, conducting wheel 3 can not reset.When motor 1 stops, frictional force reduces, and the deformation force due to spring 4 makes conducting wheel 3 reset.
The end of motor 1 axle is equipped with gear and is engaged with the first gear 2.The central part of the first gear 2 is provided with gear boss and coordinates with conducting wheel 3, realizes the first gear 2 and drives conducting wheel 3 to rotate.The central part of the first gear 2 is provided with gear boss, and the polygon projection of raised brim and casing is independent of each other when the first gear 2 rotates.Casing boss is polygon boss, and casing boss is less than in the first gear 2 central interior size, and plane and first gear 2 side at casing boss place are parallel to each other.Axle 7 end near the first gear 2 has a block plate, and block plate diameter is less than conducting wheel 3 diameter, and the plane gapless at the block plate end face of close axle 7 end and the protruding place of the polygon of casing, axle 7 end is fixed on casing.In the axle 7 being fixed on casing projection 8 near axle 7 end of the second gear 5 overlaps, axle 7 overlaps the end face gapless of end face and the second gear 5.The conducting wheel gear teeth 31, are greater than gap between the first gear 2 and the second gear 5 near the spring 4 side conducting wheel gear teeth 31 length.Conducting wheel 3 and casing projection 8 cooperatively interact, and when rotating, the distance of axial displacement of conducting wheel 3 is greater than the gap between the first gear 2 and the second gear 5.The conducting wheel gear teeth 31 of conducting wheel 3, near casing end face can with the polygon male cooperation of casing, can make when motor 1 rotates conducting wheel 3 produce move axially.The conducting wheel gear teeth 31 of conducting wheel 3 can coordinate with the second gear 5 away from the head face hump of casing, drive the second gear 5 to rotate.Conducting wheel 3 on axle 7, can move vertically.Casing protruding 8 designs for Polyhedral, coordinates with the conducting wheel gear teeth 31 of conducting wheel 3.The central part of the second gear 5 is provided with the groove coordinated with the conducting wheel gear teeth 31, groove rectangularity.Spring 4 is had between second gear 5 and conducting wheel 3, when motor 1 rotates, the first gear 2 is driven to rotate, first gear 2 drives conducting wheel 3 to rotate, the conducting wheel gear teeth 31 of conducting wheel 3 match with the boss on casing, and conducting wheel 3 is moved axially to spring 4 direction, and deformation occurs spring 4, now conducting wheel 3 engages with the second gear 5, drives the second gear 5 to rotate.When motor 1 stops operating, the deformation force due to spring 4 makes conducting wheel 3 separate with the second gear 5.Spring 4 external diameter is less than conducting wheel 3 diameter.Have a through hole in the middle of switch knob 6, be fixed on casing by switch handle shaft, one end is being portion of the handle, and for manual activity, one end becomes fan-shaped design, has gear teeth above, and gear teeth engages with the second gear 5.Axle 7 two ends are fixed on casing, and conducting wheel 3 can move axially.
Motor 1 obtains enabling signal, motor 1 rotates, the first gear 2 is driven to rotate, first gear 2 drives conducting wheel 3 to rotate, and conducting wheel 3 coordinates with casing boss, moves axially to the direction away from casing, conducting wheel 3 is coordinated with the second gear 5 (spring 4 simultaneously between the second gear 5 and conducting wheel 3 is out of shape stressed), drive the second gear 5 to rotate, the second gear 5 drives switch knob 6, thus reaches closed object.Motor 1 obtains stop signal, and motor 1 stops operating, and the frictional force between conducting wheel 3 and the first gear 2 reduces, and the elastic force due to spring 4 makes conducting wheel 3 separate with the second gear 5.The present invention solves by mechanical structure the problem that miniature circuit breaker cannot realize automatic closing, and range of application is comparatively extensive; The present invention achieves the function of open circuit automatic closing by mechanical structure, and structure of the present invention is simple, easy to operate, coefficient of safety is high, do not need manual switchover, automatically adapt to the requirement of closing by hand and automatic closing, substantially increase security performance in use.
The present invention is described in detail in preferred embodiment above by concrete; but those skilled in the art should be understood that; the present invention is not limited to the above embodiment; within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement etc., all should be included within protection scope of the present invention.
