Detailed Embodiments

[0027] In order to better understand the technical content of the present utility model, specific embodiments are hereby given and described in conjunction with the accompanying drawings as follows.

[0028] Combined with Figures 1-4 as shown, the present utility model provides a roller shutter window based on a winding system, including a winding box 1 and a guide rail 2. A winding shaft and a driving component are provided inside the winding box 1. A winding roller shutter 11 is provided on the winding shaft, and the driving component drives the winding shaft to rotate, thereby winding / unwinding the winding roller shutter 11. Two guide rails 2 are symmetrically arranged below both ends of the winding box 1. Both sides in the width direction of the winding roller shutter 11 extend into the guide rails 2, and the guide rails 2 limit the winding roller shutter 11, so that the winding roller shutter has the function of rigid protection.

[0029] In the event of an emergency such as a fire or an earthquake that causes the electric roller shutter window to fail, since a locking clutch is provided inside the electric roller shutter window, it is difficult to quickly open the winding roller shutter, which blocks the escape route, and the relatively good rigid protection performance of the winding roller shutter will increase the difficulty for rescue personnel to break it from the outside, hindering the rescue.

[0030] Combined with Figure 2 and Figure 3As shown, the guide rail 2 includes a fixed side strip 21 and a detachable side strip 22 which are interlocked, and the cross-section of the guide rail 2 forms a U-shaped structure which can limit the rolling curtain 11, thereby maintaining the rigidity of the rolling curtain 11, and the fixed side strip 21 and the detachable side strip 22 are separately arranged and can be disassembled from each other. Since the rolling curtain 11 is composed of multiple blades twisted together, after disassembly, the guide rail 2 can no longer limit the rolling curtain 11, and the rolling curtain 11 can be swung open.

[0031] Furthermore, the guide rail 2 is provided with a plurality of electromagnetic connection modules 3 along the length direction to connect the fixed side strips 21 and the detachable side strips 22 to each other. The electromagnetic connection modules 3 are configured to generate magnetism when power is on and eliminate magnetism when power is off.

[0032] In this way, when the rolling shutter is operating normally and powered on, under the action of the electromagnetic connection module 3, the fixed side strip 21 and the detachable side strip 22 are magnetically connected to each other, thereby limiting the rolling curtain 11 and maintaining the rigidity of the rolling curtain 11. When the rolling shutter is powered off due to an abnormal situation, the electromagnetic connection module 3 fails. At this time, the detachable side strip 22 can quickly detach from the fixed side strip 21, releasing the limit on the rolling curtain 11, allowing the rolling curtain 11 to swing open, and people can quickly pass through the rolling shutter.

[0033] In a specific embodiment, the electromagnetic connection module 3 includes an electromagnet 31 and a corresponding magnetic plate 32. The electromagnet 31 is connected to the fixed side strip 21, and the magnetic plate 32 is connected to the removable side strip 22. When the electromagnet 31 is energized, it is magnetically connected to the magnetic plate 32, so that the fixed side strip 21 and the removable side strip 22 are connected to each other. When the power is off, the electromagnet 31 fails, and the removable side strip 22 can be separated from the fixed side strip 21.

[0034] In an optional embodiment, the area of ​​magnetic attraction between the electromagnet 31 and the magnetic plate 32 is greater than 10 square centimeters, so that the magnetic attraction force between the electromagnet 31 and the magnetic plate 32 is sufficient to meet the requirement of limiting the rolling curtain 11.

[0035] Furthermore, since the electromagnet 31 needs to be wired and powered, the fixed side strip 21 on which the electromagnet 31 is installed is fixed to the wall, and the detachable side strip 22 is connected to the fixed side strip 21 through magnetic force.

[0036] In a preferred embodiment, a baffle 23 is provided on the removable side strip 22. When the fixed side strip 21 and the removable side strip 22 are in contact with each other, the fixed side strip 21, the removable side strip 22 and the baffle 23 form a closed cavity for enclosing the electromagnetic connection module 3, thereby protecting the electromagnetic connection module 3 and preventing malicious damage to the electromagnetic connection module 3 from the gap in the guide rail 2.

[0037] Combination Figure 2 , Figure 3 and Figure 4As shown in the figure, the guide rail 2 is provided with a plurality of connecting ribs 4 along the length direction for connecting the fixed side strip 21 and the detachable side strip 22. During installation or accidental power failure, the connecting ribs 4 can play a connecting role to prevent the detachable side strip 22 from accidentally falling off.

[0038] Furthermore, a V-shaped groove for guiding the self-breaking under force is formed on the connecting rib 4. Under the action of an external force, the detachable side strip 22 can easily fall off. In case of an emergency power failure, the retractable curtain 11 can be directly pushed outwards. At this time, the connecting rib 4 is subjected to a tensile force and breaks along the V-shaped groove, so that the detachable side strip 22 falls off, without affecting the quick opening of the retractable curtain 11.

[0039] Combined with Figure 2 and Figure 3 As shown in the figure, connection caps 41 are provided at both ends of the connecting rib 4. A first connecting member corresponding to the connection cap 41 is provided on the fixed side strip 21, and a second connecting member corresponding to the connection cap 41 is formed on the detachable side strip 22. One end connection cap 41 is detachably connected to the fixed side strip 21 through the first connecting member, and the other end connection cap 41 is detachably connected to the detachable side strip 22 through the second connecting member, so that the connecting rib 4 can be disassembled and replaced. After the connecting rib 4 is broken due to emergency use, the guide rail 2 can be reset by replacing a new connecting rib 4.

[0040] In a specific embodiment, the first connecting member includes a screw 24, and the connection cap 41 is threadedly connected to the screw 24. The second connecting member includes a bolt 25 and a mounting hole 201 formed in the detachable side strip 22. The bolt 25 passes through the mounting hole 201 and is threadedly connected to the connection cap 41.

[0041] In an alternative embodiment, the bolt 25 is a cross-shaped flat head bolt.

[0042] In a preferred embodiment, the connecting rib 4 is made of aluminum, which has good anti-rust performance and will not rust and break during long-term use in outdoor environments, and has a high service life.

[0043] Combined with the above embodiments, by setting the guide rail 2 into a split structure composed of a fixed side strip 21 and a detachable side strip 22, and magnetically connecting the fixed side strip 21 and the detachable side strip 22 through an electromagnet 31. When the rolling shutter window operates normally and is powered on, under the action of the electromagnet 31, the fixed side strip 21 and the detachable side strip 22 are magnetically connected to each other to realize the limitation of the retractable curtain 11 and maintain the rigidity of the retractable curtain 11. When the rolling shutter window is powered off due to an abnormal situation, the electromagnetic connection module 3 fails. At this time, the detachable side strip 22 can quickly disengage from the fixed side strip 21, release the limitation on the retractable curtain 11, and enable the retractable curtain 11 to swing open, so that people can quickly pass through the rolling shutter window.

[0044] Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Those of ordinary skill in the technical field to which the present utility model pertains may make various modifications and refinements without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to that defined by the claims.
