[0026] The auxiliary unlocking device according to the exemplary embodiments of the present application comprises a rod body 1, a magnetic attraction member 2 and a flexible connecting member 3.

[0027] Specifically, the rod body 1 has an extension part 11 and a hand-held part 12 connected to the extension part 11, and the extension part 11 and the hand-held part 12 have a turning angle therebetween; the magnetic attraction member 2 is slidably connected to the extension part 11 so as to enable the magnetic attraction member 2 to slide along the length direction of the extension part 11; and the flexible connecting member 3 is connected to the magnetic attraction member 2 so as to drive the magnetic attraction member 2 to slide along the length direction of the extension part 11.

[0028] That is, the operator forms a gap on the door leaf around the lock head of the roller shutter door by cutting, and disconnects the lock head from the telescopic rod. The operator inserts the extension part 11 into the gap by holding the hand-held part 12, and turns the extension part 11 through the turning angle, so that the magnetic attraction member 2 on the extension part 11 approaches and is attracted to the telescopic rod. Then, the operator pulls the flexible connecting member 3 to make the magnetic attraction member 2 slide along the length direction of the extension part 11, so as to pull the telescopic rod out of the locking hole of the door frame or wall, and the roller shutter door is in an unlocked state that can be opened. The flexible connecting member 3 can be a rope or a flexible metal strip made of various materials.

[0029] Therefore, the magnetic attraction member 2 is slidably arranged on the rod body 1, and the rod body 1 is provided with a bending angle, so that the operator can insert the rod body 1 into a narrow gap and turn it, so that the magnetic attraction member 2 approaches and is attracted to the telescopic rod. Then, the operator pulls the flexible connecting member 3 to make the magnetic attraction member 2 drive the telescopic rod to move, so as to make the roller shutter door in an unlocked state. The auxiliary unlocking device has a simple structure and is easy to operate. The telescopic rod of the roller shutter door can be quickly pulled to make the roller shutter door in an unlocked state.

[0030] ​For the sliding connection of the magnetic member 2 and the extension 11, the extension 11 defines a sliding groove 111 along the length direction thereof, and the magnetic member 2 is connected to the sliding groove 111 to enable the magnetic member 2 to slide along the extension 11. It can be understood that, by connecting the magnetic member 2 to the sliding groove 111 of the extension 11, the magnetic member 2 is enabled to slide along the length direction of the extension 11, facilitating the movement of the telescopic rod when the magnetic member 2 slides. The extension 11 can be a straight segment, facilitating the matching of the installation state of the telescopic rod to pull the telescopic rod.

[0031] For the extension of the flexible connecting member 3, the handheld portion 12 is provided with a channel 121 along the length direction thereof, which is in communication with the sliding groove 111, and the flexible connecting member 3 passes through the channel 121 and the sliding groove 111 to connect the magnetic member 2. It can be understood that, by passing through the channel 121 and the sliding groove 111 and then connecting the magnetic member 2, the operator can pull the flexible connecting member 3 from the handheld portion 12 to slide the magnetic member 2, which is more convenient for operation, and at the same time, the flexible connecting member 3 can be protected to avoid being scratched by the edge of the gap of the roller shutter door, thereby preventing the flexible connecting member 3 from being worn or damaged. The extension 11 and the handheld portion 12 can be integrally formed metal pipes, or can be separately designed and then connected by welding or an adapter, and the sliding groove 111 can be formed by cutting the extension 11 to expose the hollow portion, and the channel 121 can be formed by the hollow portion of the handheld portion 12.

[0032] For the magnetic member 2, the magnetic member 2 has a mounting portion 21 and a magnetic portion 22 arranged on the mounting portion 21, the mounting portion 21 is slidably connected to the sliding groove 111, and the flexible connecting member 3 is connected to the mounting portion 21. It can be understood that, by arranging the mounting portion 21, the magnetic portion 22 can be slidably connected to the extension 11, thereby facilitating the sliding of the magnetic member 2. The mounting portion 21 can be provided with a groove, which can be matched with the convex edge of the sliding groove 111 to limit the mounting portion 21 to slide in the sliding groove 111, thereby preventing the mounting portion 21 from falling off during sliding; or the diameter of the part of the mounting portion 21 in the hollow portion can be greater than the width of the sliding groove 111, so as to limit the mounting portion 21 in the sliding groove 111; the magnetic portion 22 can be a cylindrical magnet, and the mounting portion 21 can be provided with a mounting hole, and the magnet is arranged in the mounting hole.

[0033] For the magnetic portion 22, the direction of attraction of the magnetic portion 22 is arranged on the same side as the free end of the handheld portion 12. It can be understood that, by arranging the direction of attraction of the magnetic portion 22 on the same side as the free end of the handheld portion 12, the operator can use the handheld portion 12 as a reference to attract the magnetic portion 22 to the telescopic rod when the telescopic rod cannot be clearly seen, and it is also helpful for the operator to exert force. The direction of attraction of the magnetic portion 22 can be perpendicular to the sliding direction thereof.

[0034] For the connection of the extension part 11 and the handheld part 12, the adapter 4 is connected between the extension part 11 and the handheld part 12, so that the extension part 11 and the handheld part 12 have a turning angle. Understandably, through the adapter 4, the connection between the extension part 11 and the handheld part 12 can be formed, and at the same time, the turning angle between the two can be formed. The extension part 11, the handheld part 12 and the adapter 4 can be sleeved or connected by threads. When not in use, the handheld part 12 and the extension part 11 can be disassembled for storage. The one end of the sliding groove 111 near the handheld part 12 can be an open end, and the other end can be a closed end. In this way, the installation part 21 can be prevented from sliding out of the sliding groove 111, and at the same time, the installation part 21 can be easily installed into the sliding groove 111 from the open end, improving the installation efficiency. After the installation part 21 is installed into the sliding groove 111, the adapter 4 and the extension part 11 are assembled and connected. In this way, the open end can be changed into a closed end, and the installation part 21 can be completely limited to slide in the sliding groove 111.

[0035] For the turning angle, the turning angle is 90°-150°. Understandably, through the setting of the turning angle of 90°-150°, the extension part 11 can be turned into the gap while facilitating the pulling of the flexible connecting piece 3, avoiding that the flexible connecting piece 3 forms a large resistance at the turning angle, and facilitating the pulling and pushing of the flexible connecting piece 3. The turning angle can be 120°.

[0036] For the flexible connecting piece 3, the flexible connecting piece 3 is a steel wire rope. The steel wire rope is a standard part, has strong tensile strength and wear resistance, and has low cost. Therefore, the overall device can be more durable and have lower manufacturing cost. A handle can be connected to the pulling end of the steel wire rope, facilitating the pulling of the operator.
