Further, the gear is equipped with handle.

Further, the gear is equipped with handle, and the gear drive and the handle pass through rotation Axis connection drives the rotation axis to rotate and drives the gear drive by the rotation of the handle.

Further, the gear drive includes the transmission gear coaxial with the rotation axis, and by described The dynamic synchromesh gear of drive gears turn, the synchromesh gear and the tray are coaxial, and the tray is driven to rotate.

Further, the buckle both ends are in claw type, for being fastened on the curtain sheet two sides of rolling screen door.

Further, the stress mandril is to be detachably connected with the drawstring.

Further, the stress mandril is scalable stress mandril.

Further, position-limit mechanism is equipped in the tray, the position-limit mechanism includes coaxial with the tray Helical teeth disk and helical teeth limit card block, to limit the revolution of tray.

Further, the position-limit mechanism is additionally provided with the release switch for releasing limit in the tray back side.

Further, the drawstring is steel cable.

Utility model has the advantages that the utility model structure is simple, and it is easy to use, it can be under emergency rating quickly Rolling screen door is opened on ground, avoids damage rolling screen door.

Specific embodiment

It please refers to shown in Fig. 1 and Fig. 2, a kind of rolling screen door emergency opening device of the utility model, including a wire coiling and releasing Set with stress mandril 3, the take-up and pay-off device includes sequentially connected gear 1, tray 2, the take-up and pay-off device It is fixed in rolling screen door 100 by a buckle 4, the top of the stress mandril 3 is connect with the tray 2 by drawstring 5；Institute It states and is equipped with gear drive 11 in gear 1, drive the tray 2 to rotate by the gear drive 11, The drawstring 5 is set to withdraw the tray 2 under the opposite force effect of the stress mandril 3.

In one embodiment of the utility model by the way of manual actuation, hand is equipped on the gear 1 Handle 12, the gear drive 11 drive institute by the rotation of the handle 12 by rotation axis connection with the handle 12 Rotation axis is stated to rotate and drive the gear drive 11.

As shown in figure 3, in one embodiment of the utility model, the gear drive 11 includes and the rotation The coaxial transmission gear 111 of axis, and the synchromesh gear 112 rotated, the synchromesh gear are driven by the transmission gear 111 112 is coaxial with the tray 2, and the tray 2 is driven to rotate.

In order to keep device easy to carry, handle 13 is equipped on the gear 1.

4 both ends of the buckle are in claw type, for being fastened on the curtain sheet of rolling screen door 100.Make gear 1 and tray 2 are accordingly fixed in rolling screen door 100.

In order to keep device easy to carry, the stress mandril 3 is to be detachably connected with the drawstring 5.

The stress mandril 3 is scalable stress mandril.Be used to support gear 1 and tray 2, effect first is that It is easy to carry, second is that height can be adjusted according to demand.

In order to keep drawstring 5 stronger, limiting the drawstring 5 is steel cable.

It is more laborsaving in order to make to operate, position-limit mechanism 6 is equipped in the tray 2, the position-limit mechanism 6 includes and institute The coaxial helical teeth disk 61 of tray 2 and helical teeth limit card block 62 are stated, the revolution of tray 2 is limited.

The position-limit mechanism 6 is additionally provided with the release switch (not shown) for releasing limit in 2 back side of tray, can High speed payout.As shown in Figure 4.

Application method:

Wirerope 5 is pulled out, 5 one end of wirerope is hung over 3 top of mandril, passes through the shake band nutating gear of handle 12 111, transmission gear 111 drives synchromesh gear 112 (synchromesh gear 112 and tray 2 are coaxial), and wirerope 5 is slowly taken in and is arrived In tray 2, achieve the purpose that rolling screen door 100 is opened.
