Above-mentioned technical proposal of the present utility model is understood for convenience, below by way of new to this practicality in specifically used mode
The above-mentioned technical proposal of type is described in detail.
Control block and lower control block are threaded with control shaft, it can in axial direction be moved when control shaft rotates
Dynamic, after rolling screen door is moved into place, the control block in control shaft touches limit switch.
When specifically used, when rolling screen door needs up, motor 11 is rotated forward, and linkage is driving spline slide hypotenuse gear 6 just
Turn, now the tooth angle (teeth groove 8) on spline slide hypotenuse gear 6 coincide with the tooth angle (teeth groove 8) on hypotenuse chain pitch wheel 9, leads to
The frictional force for crossing tooth angle slip drives hypotenuse chain pitch wheel 9 to rotate forward, and is driving rolling screen door roller gear 13 just by driving chain
Turn so that rolling screen door is up, when rolling screen door it is up in place after upper control block touch up limit switch K2, up limit switch K2
Disconnect, motor 11 stops operating.
When rolling screen door needs normal descending, motor 11 is inverted, and linkage drives spline slide hypotenuse gear 6 to invert, now,
Acted on by return spring 4, tooth angle and the tooth angle on hypotenuse chain pitch wheel 9 of spline slide hypotenuse gear 6 coincide, and utilize roller shutter
The frictional force that the gravity and tooth angle of door itself are slided provides power, and rolling screen door is normally descending, when rolling screen door it is descending in place after lower control
Clamp dog touches descending limit switch K1 and bounce-back alarm limit switch K3, and descending limit switch K1 disconnections, motor 11 stops operating,
Rebound the alarm limit switch K3 bounce-back terminals power-off that is hampered simultaneously, and electricity on alarm terminal, warning function starts, when having
When people forces open the door, rolling screen door, which rises, drives rolling screen door roller gear 13 and hypotenuse chain pitch wheel 9 to rotate, the tooth of hypotenuse chain pitch wheel 9
Angle rotates forward and rubbed with the tooth angle on static spline slide hypotenuse gear 6, the compression return bullet of spline slide hypotenuse gear 6
Spring 4 is moved to the direction of reductor 12, during exercise the card of the disk 7 extruding double loop limit switch of spline slide hypotenuse gear 6
14, normally closed loop is powered off, electricity in normal open circuit, and power firestreak, audible-visual annunciator and zero-power line constitute closed-loop path, acousto-optic report
Alert device sends alarm.
When rolling screen door is descending to be hampered, the rolling screen door roller gear 13 and hypotenuse chain pitch wheel 9 of linkage will be static, due to this
When motor 11 will normally invert, the reversion of the tooth angle of spline slide hypotenuse gear 6 and the tooth angle on static hypotenuse chain pitch wheel 9
Rub, the compression retracteding position spring 4 of spline slide hypotenuse gear 6 is moved to the direction of reductor 12, and spline slide is oblique during exercise
The card of the disk 7 extruding double loop limit switch 14 of side gear 6 so that electricity in normally closed loop power-off, normal open circuit, it is now electric
The former power firestreak power-off of machine 11, new power firestreak commutation access motor 11, motor 11 is rotated forward, subsequent spline slide hypotenuse tooth
Wheel 6 returns to original position, the time-delay reset of double loop limit switch 14 in the presence of return spring 4, and motor 11, which continues to rotate forward, drives volume
Curtain door is up in place.
During actual installation, it is divided into left and right motor, two motors are respectively arranged with above-mentioned dynamical system and control system, work
Make principle ibid.
In summary, by above-mentioned technical proposal of the present utility model, overcoming existing rolling screen door can not be hampered automatic liter
The defect risen, it is to avoid door piece is damaged, with rational in infrastructure, the characteristics of fault rate is low, service life is long；With anti-theft feature,
It is safe.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw under enlightenment of the present utility model
Other various forms of products, however, make any change in its shape or structure, it is every that there is same as the present application or phase
Approximate technical scheme, all falls within protection domain of the present utility model.
