The utility model content
The purpose of the utility model is to provide a kind of air circuit operating mechanism, and simple in structure, volume is little, and cost is low, and reliability is higher.
The described air circuit operating mechanism of the utility model; Be provided with the shifting block that is connected with circuit breaker handle; One side of shifting block is provided with the curve orientation groove of S shape, and the finger that is connected on the crank places the curve orientation groove, and the ratio wheel on the crank axle is associated with the active drive wheel.
Simple in structure, volume is little, and cost is low; The active drive wheel drives crank axle initiatively through ratio wheel, and the crank of rotation drives finger, and finger is stirred shifting block in the curve orientation groove; Shifting block drives circuit breaker handle and moves, and accomplishes the combined floodgate or the disjunction of circuit breaker, and reliability is higher.
Crank can be replaced by associated components such as disk, eccentric discs; Finger can reduce friction for the bearing pin that rotates; When driving mechanism is arranged at a slow speed, the deceleration transmission part can be saved, corresponding adjustment can be done according to demand.
In the utility model:
Ratio wheel is designed to reduction gearing, and the active drive wheel is for connecting the driving gear of motor, and reduction gearing and driving gear are meshed, and structure is simpler, motor-driven, and transmission is more reliable, can realize automatic control.Used motor can be alternating current machine, also can be direct current machine.During motor band reduction box, can omit the deceleration transmission part.
Reduction gearing can be installed on the crank axle through unilateral bearing, at the other end of crank axle passive bevel gear is installed, and passive bevel gear is meshed with driving bevel gear, and the gear shaft of driving bevel gear is provided with the spanner junction, thereby can realize manual control.The setting of unilateral bearing can make manually and can independently carry out respectively automatically, does not disturb mutually.
It is perpendicular that crank axle and gear shaft are provided with, and the spanner junction is arranged on the top of gear shaft, for the many ribs notch that adapts with many ribs spanner, simple in structure, easy to operate.
The state indicating dial is established at corresponding teeth wheel shaft top, and the state indicating dial is provided with and closes, divides mark, and convenient combined floodgate or the disjunction state of observing air circuit comes into plain view.
The beneficial effect of the utility model is:
Simple in structure, volume is little, and cost is low, and reliability is high, can also realize two kinds of automatic, manual modes of operation, and is easy to operate.
Not only be used on the air circuit also suitable being used on other switch of similar action.
Description of drawings
Fig. 1, the utility model one embodiment are combined in the structural representation under the application state.
The vertical view of Fig. 2, Fig. 1.
Fig. 3, block-dialing structure enlarged diagram.
Among the figure: 1, shifting block 2, finger 3, eccentric disc 4, bearing pedestal 5, reduction gearing 6, crank axle 7, many ribs notch 8, state indicating dial 9, driving bevel gear 10, passive bevel gear 11, unilateral bearing 12, connection base 13, circuit breaker 14, curve orientation groove.
Embodiment
Below in conjunction with embodiment the utility model is described further.
As shown in the figure; The described air circuit operating mechanism of the utility model is provided with the shifting block 1 that is connected with circuit breaker handle, and a side of shifting block 1 is provided with the curve orientation groove 14 of S shape; The finger 2 that is connected on the eccentric disc 3 places curve orientation groove 14; Ratio wheel on the crank axle 6 is a reduction gearing 5, and the active drive wheel is for connecting the driving gear of motor, and reduction gearing 5 is meshed with driving gear.Reduction gearing 5 is installed on the crank axle 6 through unilateral bearing 11; The other end of crank axle 6 is equipped with passive bevel gear 10; Passive bevel gear 10 is meshed with driving bevel gear 9, and crank axle 6 is perpendicular with gear shaft, and the gear shaft top is provided with the many ribs notch 7 that adapts with many ribs spanner.Corresponding teeth wheel shaft top is provided with state indicating dial 8, and state indicating dial 8 is provided with and closes, divides mark.
The utility model is fixed on the circuit breaker 13 through connecting base 12.
Course of action:
(1) electric operating process
Motor-driven driving gear 5 drives crank axle 6 through unilateral bearing 11 and rotates, and crank axle 6 drives eccentric disc 3 and rotates; Eccentric disc 3 drives finger 2 actions; Finger 2 moving in curve orientation groove 14 promotes shifting block 1 drive circuit breaker handle and moves, and accomplishes the combined floodgate or the disjunction of circuit breaker.Simultaneously, the passive bevel gear 10 on the crank axle 6 drives driving bevel gear 9, and gear shaft rotates, thereby disjunction direction board 8 rotates the combined floodgate of instant playback air circuit or disjunction state.
(2) manual operation process
With many ribs spanner, through many ribs notch 7 gear shaft, driving bevel gear 9 rotates; Drive passive bevel gear 10 and rotate, passive bevel gear 10 drives crank axle 6 and rotates, under the effect of unilateral bearing 11; Crank axle 6 can only rotate to a direction, and crank axle 6 drives eccentric disc 3 and rotates, and eccentric disc 3 drives finger 2 actions; Finger 2 moving in curve orientation groove 14 promotes shifting block 1 drive circuit breaker handle and moves, and accomplishes the combined floodgate or the disjunction of circuit breaker.
Because the setting of unilateral bearing 11, realize that electronic automatic operation and manual operation do not disturb mutually.
