Now skid.
Further improve, first leading screw, the second leading screw are respectively arranged with proximity switch, connect on one end of bearing
Nearly switch is electrically connected between control device.By being positioned proximate to switch, in door opening process, the first Xie Men mechanisms, second are taken
Door mechanism contacts to two ends proximity switch, then driving means quit work, prevent the first Xie Men mechanisms, the second Xie Men mechanisms from touching
Support is hit, causes whole device unstability, damaged.
Further improve, also including supporting slider mechanism, the supporting slider mechanism includes support bar and two sliding sleeves,
Strut two ends are fixed on support, and support bar be arranged in parallel with the first leading screw, the second leading screw, the equal slidingtype of described two sliding sleeves
It is set on support bar, and two sliding sleeves are connected respectively with the first Xie Men mechanisms, the second Xie Men mechanisms.
Further improve, the motor is bolted on support, is easy to remove and repair and changes.
Compared with prior art, the beneficial effects of the utility model are：
1st, by being positioned proximate to switch, in door opening process, the first Xie Men mechanisms, second take a mechanism contacts and arrive two ends
Proximity switch, then driving means quit work, prevent the first Xie Men mechanisms, the second Xie Men mechanisms collision support, cause whole dress
Unstability is put, is damaged.
2nd, by arranging supporting slider mechanism, support bar plays a part of to make to Xie Men mechanisms, load-bearing, prevents first
Thick stick, the second leading screw deform because of excessive load-bearing.
3rd, by arranging servo electricity, control accuracy is high, and high speed performance is good, and strong adaptability can bear and be three times in nominal torque
Load, low cruise is steady, and the dynamic corresponding time of motor acceleration and deceleration is short, and heating and noise are substantially reduced.
4th, connected by synchronous cog belt between transmission mechanism and motor, control accuracy is high, be not in skid.
5th, motor is bolted on support, is easy to remove and repair and is changed.
