Description
Technical field
This utility model relates to a kind of switchgear, particularly relates to the operation module of a kind of small air switch.
Background technology
The driving module (grasping module also known as electricity) of existing small air switch, can realize driving switch separating brake for switch should be driven to close a floodgate again, current existing a kind of scheme is: use the handle of motor-driven miniature circuit breaker to close a floodgate, and then rotates further through motor opposite direction and carries out separating brake.Its motor and gear mechanism running order be: after motor and gear mechanism thereof drive switch in-place closing, and due to ensuing sub-switching operation likely for manual operation, for making drive mechanism be no longer bear against handle, motor needs to rotate backward immediately；Need also exist for again rotating backward when separating brake completes rear motor, make drive mechanism be no longer bear against handle, be beneficial to carry out closing by hand.So causing the frequent forward and reverse rotation of motor, the life-span is low.For overcoming above-mentioned deficiency, utility model patent CN 203377186 U proposes a kind of employing and is similar to the scheme of clutch function to avoid motor frequently to rotate, but its structure is complex, and reliability is low.
A kind of scheme additionally is: drives only with motor and closes a floodgate, needs also exist for motor and rotate backward immediately, make drive mechanism be no longer bear against handle, it is simple to can carry out sub-switching operation after in-place closing；Still further it is provided with an electric magnet for threading off, makes breaker open operation.This structure, owing to having had more electric magnet and releasing structure thereof, occupies more space, and cost is high.
Utility model content
The purpose of this utility model is to provide the operation module of the small air switch of a kind of simple in construction, reliable in action, low cost.
For achieving the above object, technical solution of the present utility model is:
This utility model is the operation module of a kind of small air switch, including circuit breaker handle, dropout part, the first gear, the second gear, the 3rd gear；The first described gear is fan-shaped partial gear, and the angle of its fan-shaped local tooth is 90 degree, and the inner of the first gear and circuit breaker handle is all socketed in the first rotating shaft, for being coaxially disposed；The second described gear is in-line gears, is made up of gear wheel and little gear, and little gear is for fan-shaped partial gear and which is provided with boss, and little gear and the engagement of the first gear, the boss on little gear can lean with the boss on dropout part in rotary course.
The fan-shaped local tooth angle degree of the described little gear in the second gear is 90 degree, and it extends described boss along the axial direction of one tooth of outermost.
One end of described dropout part has axis hole and this dropout part axis hole and chopper tripping concentric, the other end of dropout part have the collar and this dropout part collar with the 3rd gear concentric in train of reduction gears.
After using such scheme, owing to this utility model is mainly made up of dropout part, the first gear, the second gear, by cooperating between dropout part, the first gear, the second gear so that this utility model uses a set of motor+gear driven mechanism, can realize closing a floodgate, separating brake can be realized again；Motor has only to one direction and rotates；Separating brake uses the mode of the dropout driving gear driven switch internal, does not relies on handle, even if user misoperation handle combined floodgate also will not damage chopper after separating brake；Simple and reliable for structure, reliable in action, save space, compact, cost is relatively low.
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.

Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 5, this utility model is the operation module of a kind of small air switch, including circuit breaker handle 1, the 2, first gear the 3, second gear the 4, the 3rd gear the 5, first rotating shaft 6 of dropout part.
The first described gear 3 is fan-shaped partial gear, and the angle [alpha] of its fan-shaped local tooth is 90 degree (angles of i.e. closing a floodgate), and the inner of the first gear 3 and circuit breaker handle 1 is all socketed in the first rotating shaft 6, for being coaxially disposed.
Shown in Fig. 4, one end of described dropout part 2 has axis hole 21, and the other end has the collar 22, and side in the middle extends outward described boss 23.One end of described dropout part 2 has axis hole 21 and this dropout part 2 axis hole 21 and chopper tripping 7 concentric, and the other end of dropout part 2 has the collar 22 and this dropout part 2 collar 22 and the 3rd gear 5 concentric in train of reduction gears.
Shown in Fig. 3, the second described gear 4 is in-line gears, is made up of gear wheel 41 and little gear 42, and little gear 42 is fan-shaped partial gear, the fan-shaped local tooth angle degree of this little gear 42 is 90 degree, and it extends described boss 421 along the axial direction of one tooth of outermost.Described little gear 42 engages with the first gear 3, and the boss 421 on little gear 42 can lean with the boss 23 on dropout part 2 in rotary course.
Operation principle of the present utility model:
As Figure 1-Figure 4, this utility model fully understands the characteristic that angle is 90 ± 20 degree that make use of needed for breaker closing, the gear (the second gear 4) of driving handle rotates the angle 360 degree of a week, can be divided into drive the angle needed for closing a floodgate and the angle needed for idle stroke angle, separating brake and idle stroke angle completely.Drive scheme only with a set of motor+gear, motor is slowed down by gear mechanism and drives when closing a floodgate the circuit breaker handle 1 of miniature circuit breaker to close a floodgate, combined floodgate rear motor is rotated further certain angle, the first gear 3 making driving gear (the second gear 4) be connected with handle disengages, and now can operate with manual brake separating；Use during separating brake and drive gear (the second gear 4) to drive dropout part 2, make switch that separating brake to occur, when driving gear (the second gear 4) to withstand dropout part 2 and not skid off, although now switch handle can close a floodgate, but the contact of switch cannot close a floodgate, this is highly beneficial when closing a floodgate preferential for not allowing to switch；Motor is that one direction rotates, and reduces carbon brush for electric machine abrasion；Drive close a floodgate with separating brake for same set of mechanism, save space, simple and reliable for structure, low cost.
Boss 421 on the medium and small gear of this utility model 42 can drive dropout part 2 in certain angular range, thus drives circuit breaker tripping, when the second gear 4 is in and withstands dropout part and do not deviate from so that chopper cannot close a floodgate.
End the first gear 3 drives circuit breaker handle 1 to rotate by an axle, and the angle of the first gear 3 fan-shaped local tooth is to drive the combined floodgate angle needed for chopper.Second gear 4 can be rotated further by a range of idle stroke angle after driving breaker closing to complete, and makes the first gear 3 disengage mutually with the second gear 4, does not affect manual divide-shut brake.When second gear 4 is further continued for rotating, the boss 421 on the second gear 4, by promotion dropout part 2, makes chopper thread off (not relying on handle) from inside, reaches the purpose of separating brake.
Due to dropout part 2 axis hole 21 and chopper tripping 7 concentric, during dropout, dropout part 2 is minimum with the tripping of switch internal friction so that dropout part 2 does not affect the characteristic of switch itself, and dropout part 2 can reset with switch internal and need not arrange a reduction torsion spring again.Again due to dropout part 2 collar 22 with the 3rd gear 5 concentric in train of reduction gears so that this utility model simple in construction, and space can be saved to greatest extent.
The above, it is only this utility model preferred embodiment, therefore can not limit, with this, the scope that this utility model is implemented, the equivalence change i.e. made according to this utility model claim and description with modify, all should still belong in the range of this utility model patent contains.
