Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
As shown in Figure 1-2, the lower section limit on the right-right-hand limit position of left synchronous belt 13 will be installed on the right side of left curtain, right curtain
Left side is installed to the lower section limit on the left position of right synchronous belt 23, and at this moment curtain is in full closeding state；As left direct current generator M1
Energization turns clockwise, right direct current generator M2 energization rotate counterclockwises when, the left belt pulley 12 of synchronous belt 13 and second also up time
Pin rotates, and pulls and is moved to the left on the right side of left curtain, now the right belt pulley 22 of synchronous belt 23 and the 4th also rotate counterclockwise, draws
Move and moved right on the left of right curtain, pull open curtain；When left direct current generator M1 energizations rotate counterclockwise, right direct current generator M2 lead to
When electricity turns clockwise, the direction of motion of synchronous belt and belt pulley also with the above-mentioned direction of motion on the contrary, pull two acts of left and right to
Opposite direction moves, and closes up curtain.
As shown in figure 3, positive switch K1 and reverser K2 switchs for DPDT formula, and under conventional sense, left forward direction
Movable contact K10 and the second from left forward direction stationary contact K12 closures, right positive movable contact K10 ' and two positive stationary contact K12 ' of the right side are closed, are left
Reverse movable contact K20 stationary contact K22s reverse with the second from left is closed, right reversely movable contact K20 ' and two reverse stationary contact K22 ' of the right side are closed
Close；When pressing positive switch K1 or reverser K2, left positive movable contact K10 and the first from left forward direction stationary contact K11 closures, the right side are just
Closed to movable contact K10 ' stationary contact K11 ' closures positive with the right side one or the left reversely movable contact K20 and reverse stationary contact K21 of the first from left
Close, right reversely movable contact K20 ' and one reverse stationary contact K21 ' of the right side is closed.
When stage has performance, needs draw curtain to move, voltage-stabilized power supply plug can be intervened 220V AC powers, voltage-stabilized power supply
220V alternating currents are converted into 12V DC electricity output, master switch S, relay J magnet coils form closed-loop path, have electric current to lead to
Cross, produce electromagnetic force, close relay J normally opened contacts.
If now pressing positive switch K1, forward direction switch K1 left positive movable contact K10 and the first from left forward direction stationary contact K11
Closure, right positive movable contact K10 ' and one positive stationary contact K11 ' of the right side are closed, and left direct current generator M1 and right direct current generator M2 is powered
Rotation；
Left direct current generator M1 and right direct current generator M2 power-on circuit is：Power supply 12V → fuse FU → relay J contacts
→ controlling switch K → forward direction switch K1 the first from left forward direction stationary contact K11 switchs K1's with left positive movable contact K10 closures, forward direction
Right positive movable contact K10 ' stationary contact K11 ' closures positive with the right side one → left direct current generator M1, right direct current generator M2 → reverser
The K2 reverse movable contact K20 in left side stationary contact K22 closures reverse with the second from left, reverser K2 right reversely movable contact K20 ' and the right side two
Reverse stationary contact K22 ' closures → bonding E, forms loop, and it is counterclockwise that now direct current generator M1 energizations turn clockwise, M2 is powered
Rotation, the left belt pulley 12 of synchronous belt 13 and second also turn clockwise, pull and be moved to the left on the right side of left curtain, now right same
The belt pulley 22 of belt 23 and the 4th also rotate counterclockwise is walked, pulls and is moved right on the left of right curtain, pull open curtain.
If unclamping positive switch K1 at an arbitrary position, contact sets back, and left positive movable contact K10 and the second from left forward direction are quiet
Contact K12 closures, right positive movable contact K10 ' and two positive stationary contact K12 ' of the right side are closed, now left direct current generator M1, right direct current
The equal bonding in motor M2 both ends, due to the braking action of armature-reaction, left direct current generator M1 and right direct current generator M2 stop rapidly.
If now pressing reverser K2, the reverser K2 reverse movable contact K20 and reverse stationary contact K21 of the first from left in a left side
Closure, right reverse movable contact K20 ' and one reverse stationary contact K21 ' of the right side are closed, and left direct current generator M1, right direct current generator M2, which are powered, to be revolved
Turn；
Left direct current generator M1, right direct current generator M2 power-on circuit are：Power supply 12V → fuse FU → relay J contacts
→ controlling switch K → reverser K2 reverse movable contact the K20 in left side stationary contact K21 closures reverse with the first from left, right reverse movable contact
K20 ' stationary contact K21 ' closures reverse with the right side one → left direct current generator M1, right direct current generator M2 → forward direction switch K1's is left positive dynamic
Contact K10 and the second from left forward direction stationary contact K12 closures, right positive movable contact K10 ' and right two positive stationary contact K12 ' closures → bonding
E, loop is formed, now left direct current generator M1 energizations rotate counterclockwise, right direct current generator M2 are powered and turned clockwise, left synchronous skin
The belt pulley 12 of band 13 and second also rotate counterclockwise, pulls and is moved right on the right side of left curtain, now right synchronous belt 23 and
Four belt pulleys 22 also turn clockwise, and pull and are moved to the left on the left of right curtain, close up curtain.
If unclamping reverser K2 at an arbitrary position, contact sets back, and left reversely movable contact K20 and the second from left are reversely quiet
Contact K22 closures, right reversely movable contact K20 ' and two reverse stationary contact K22 ' of the right side are closed, now left direct current generator M1, right direct current
The equal bonding in motor M2 both ends, due to the braking action of armature-reaction, left direct current generator M1 and right direct current generator M2 stop rapidly.
Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real
The content being not limited to new technical scope on specification, it is necessary to which its technology is determined according to right
