[0038] Embodiment 2

[0039] The present invention also provides a manual rolling curtain anti-falling device as described in any one of the above items, comprising the following steps:

[0040] 1. Installation phase

[0041] The base 1 is fixed to the wall or structure 10 below the rolling door 11 by a plurality of base bolts 2 to ensure that the base 1 is firmly and stably installed and can withstand various forces acting on the device during operation.

[0042] The fixed shaft 3 is vertically fixedly connected to the base 1 and is located at one side below the rolling door 11 to avoid the rising or falling path of the rolling door 11 to ensure that the normal lifting and lowering of the rolling door 11 is not affected.

[0043] The rotating shaft 7 is installed, and the rotating shaft 7 is sleeved on the outside of the fixed shaft 3 so that it can rotate relative to the fixed shaft 3. Then one end of the stopper 4 (first angle steel) is fixedly connected to the rotating shaft 7.

[0044] Below the fixed shaft 3 and on one side close to the rolling door 11 , a stopper 5 (second angle steel) is vertically fixedly connected to the base 1 , also avoiding the rising or falling path of the rolling door 11 .

[0045] A reinforcing member 8 is fixedly connected below the horizontal plate of the first angle steel, and the reinforcing member 8 is fixedly connected to the base 1. The push rod shaft 9 is rotatably connected to an end of the blocking member 4 away from the fixed shaft 3, and the push rod 6 is fixedly connected to the push rod shaft 9.

[0046] 2. Normal use stage (the rolling door 11 is raised or lowered without any unexpected situation)

[0047] When the rolling door 11 is raised and not in use, the push rod 6 is pushed to drive the blocking member 4 (first angle steel) to rotate around the fixed axis 3, so that the blocking member 4 falls behind the limiting member 5 (second angle steel).

[0048] When the rolling door 11 needs to be completely closed, the push rod 6 is pushed to rotate the stopper 4 to a position where the rolling door 11 is not affected, so that the rolling door 11 can be smoothly closed.

[0049] 3. Accident response stage (rolling door 11 accidentally falls)

[0050] When the rolling door 11 falls unexpectedly, the push rod 6 is quickly pushed to drive the stopper 4 (first angle steel) to rotate around the fixed shaft 3, so that the stopper 4 rotates to the top of the limiter 5 (second angle steel) and contacts it.

[0051] At this time, the limiting member 5 (second angle steel) restricts the blocking member 4 from continuing to rotate, and the blocking member 4 is in a position where it can resist the descending rolling shutter door 11, thereby playing a role of blocking, fixing and protecting.

[0052] At the same time, the reinforcing member 8 and each connecting part work together to withstand pressure and prevent the device from being deformed or damaged.

[0053] In short, the manual rolling shutter anti-falling device can effectively ensure the safety below the rolling shutter door 11 under different circumstances through reasonable design and operation process.

[0054] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
