are further, and the below of cam described in the utility model is provided with limit base, and said limit base is provided with limited post, and said cam is provided with the circular arc spacing hole that cooperates with limited post.
are further; Bar of actuating described in the utility model and driver blade nationality are by driver blade rotating shaft cross-under; Actuating bar and driver blade fix through rivet simultaneously, and are arranged with the support sleeve between actuating bar and driver blade in the said driver blade rotating shaft.After the triggering male member on the said cam acted on the recess on the driver blade, said actuating bar just rotated around the driver blade rotating shaft.
further, transmission mechanism described in the utility model also comprises the transmission mechanism bracing frame, said driver blade rotating shaft bottom through Bearing Installation on the transmission mechanism bracing frame.
are further, are fixed with on the cam described in the utility model to be used for the continuous cam shaft of motor shaft.Specifically be to have axis hole on the said cam, said cam shaft passes axis hole, and simultaneously cam shaft bottom one is connected with pallet, and said pallet nationality is fixed by screw or rivet and cam; Use hex hole and have the location of all mating on the said cam shaft with motor shaft and inner hexagon spanner shape.When cam shaft with after motor shaft links to each other, cam is just rotated by motor-driven.
Trigger male member described in
the utility model and be preferably bearing, said bearing fixing is used to drive the driver blade activity on cam.
In
present embodiment, said two transmission mechanisms are connected with the circuit breaker of power supply commonly used with stand-by power supply one side respectively.During practical implementation, the actuating bar in the said transmission mechanism is connected with the interior slide plate of breaker operation mechanism, and when the actuating bar rotated, it was movable to drive slide plate, thereby realized the break-make of circuit breaker.
The concrete operation principle of
the utility model is following: suppose one of right side in two transmission mechanisms with duplicate supply in power circuit breaker commonly used link to each other, and of left side links to each other with auxiliaries-supply circuit-breaker.After the starter motor, when the motor-driven cam turns clockwise, the triggering male member that then is positioned at the right side on the cam at first drives the transmission mechanism action on right side.Specifically be when this triggering male member moves to the vertex position of driver blade inner recess, the actuating bar is around driver blade rotating shaft rotation and drive the breaker operation mechanism action, just can realize the combined floodgate fully of power supply commonly used in the duplicate supply.In like manner, when driving cam rotates counterclockwise, and when making the triggering male member in left side move to the driver blade recess vertex position in left side, just arrive power supply separating brake commonly used and the stand-by power supply closing position.
The mating reaction of the circular arc spacing hole in
the utility model on limited post and the cam can limit the transition rotation of cam; Thereby guarantee that the fault of this mechanism controls can not appear breaking away from power supply commonly used or stand-by power supply in combined floodgate or separating brake process, guarantee the reliability of duplicate supply work with this.
The utility model has the advantages that:
are this double power supply automatic transfer switch operating mechanism that provides of the utility model 1., and overall structure is simple, and parts are few, and are easy to process, low cost of manufacture.
are this double power supply automatic transfer switch operating mechanism that provides of the utility model 1., and its cam, driver blade are rotational structure, and rotates flexibly, and are easy to operate so the entire mechanism conversion speed is fast, functional reliability height, long service life.

Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the structural representation of the utility model.
wherein: 1, cam; 2, trigger male member; 3, driver blade; 4, actuating bar; 5, recess; 6, limited post; 7, circular arc spacing hole; 8, driver blade rotating shaft; 9, support sleeve; 10, bearing; 11, cam shaft; 12, pallet; 13, hex hole.
Embodiment
embodiment: combine shown in Figure 1, this double power supply automatic transfer switch operating mechanism that present embodiment provides, it is by the rotation trigger equipment and be divided into rotation trigger equipment both sides and be used to connect the transmission mechanism of controlling circuit breaker and constitute jointly; Wherein said rotation trigger equipment is made up of cam 1, limit base, triggering male member 2 and cam shaft 11; Corresponding each transmission mechanism all fixing one triggers male member 2 on the said cam 1; Said cam 1 below is provided with limit base (not drawing among the figure); Said limit base is provided with limited post 6, and said cam 1 is provided with the circular arc spacing hole 7 that cooperates with limited post 6.
Be fixed with on
said cam 1 and be used for the continuous cam shaft 11 of motor shaft.Specifically be to have axis hole on the cam 1, said cam shaft 11 passes axis hole, and simultaneously cam shaft 11 bottom one are connected with pallet 12, and said pallet 12 nationalitys are fixed with cam 1 by screw or rivet; And have the location of all mating on the said cam shaft 11 with hex hole 13 with motor shaft and inner hexagon spanner shape.
Two transmission mechanism structures are identical described in
present embodiment, and are symmetrically distributed in cam 1 both sides.Each transmission mechanism is formed by driver blade 3, actuating bar 4, driver blade rotating shaft 8, support sleeve 9, bearing 10 and transmission mechanism bracing frame (not drawing among the figure) are common.Said driver blade 3 is provided with and triggers the recess 5 that male member 2 matches; Said actuating bar 4 and driver blade 3 nationalitys are by driver blade rotating shaft 8 cross-under; Simultaneously actuating bar 4 and driver blade 3 fix through rivet, and are arranged with the support sleeve 9 between actuating bar 4 and driver blade 3 in the said driver blade rotating shaft 8.Said driver blade rotating shaft 8 bottoms are installed on the transmission mechanism bracing frame through bearing 10.
Triggering male member 2 described in
present embodiment is bearing, and said bearing fixing is used to drive driver blade 3 activities on cam 1.After the triggering male member 2 on the said cam 1 acted on the recess 5 on the driver blade 3, said driver blade 3 just together got up around driver blade rotating shaft 8 rotations with actuating bar 4.
In
present embodiment, as shown in Figure 1, in two transmission mechanisms one of the right side with duplicate supply in power circuit breaker commonly used link to each other, and of left side links to each other with auxiliaries-supply circuit-breaker.During practical implementation, the actuating bar 4 in the said transmission mechanism is connected with the interior slide plate of breaker operation mechanism, and when 4 rotations of actuating bar, it is movable to drive slide plate, thereby realizes the break-make of circuit breaker.
The concrete operation principle of
