[0026] The sensing component 6 includes a second fixed block 605 and a connecting block 601. The inner walls of the two symmetrical sides of the connecting frame 3 are respectively provided with mounting grooves 4, in which the sensing component 6 is installed in cooperation. A pressure sensor 607 is fixedly installed on one side of the two mounting grooves 4 away from each other. The second fixed block 605 is respectively fixedly installed in the middle of the inner wall of the two mounting grooves 4. A sliding groove 606 is fixedly installed in the middle of the second fixed block 605. A sleeve 604 is fixedly installed in the middle of the inner wall of the sliding groove 606. The inner wall of the sleeve 604 A connecting rod 603 is slidably installed, a connecting block 601 is fixedly installed on the side of the connecting rod 603 away from the pressure sensor 607, a resistance block 602 is fixedly installed on the side of the connecting block 601 away from the connecting rod 603, a second fixed block 605 extends outward from a side close to the connecting block 601, a spring 608 is sleeved on the outside of the second fixed block 605, the spring 608 is fixedly installed on the second fixed block 605, and the connecting block 601 is fixedly installed on the side of the spring 608 away from the second fixed block 605.

[0027] In this embodiment, refer to Figure 1 and Figure 2 As shown, the connection frame 3 is symmetrically provided with receiving grooves 5 on both sides thereof, and the two receiving grooves 5 are provided with fixing components 7. Figure 1 and Figure 3 As shown, the fixing assembly 7 includes a cylinder 701, and the cylinder 701 is fixedly installed on the inner wall of the two storage grooves 5 on the side away from each other. A clamping block 702 is fixedly installed on the telescopic end of the cylinder 701. When the cylinder 701 is started, the two clamping blocks 702 pressurize and clamp the flexible lifting door body 1 to fix the flexible lifting door body 1 and prevent the flexible lifting door body 1 from continuing to descend.

[0028] In this embodiment, refer to Figure 2 and Figure 3 As shown, the clamping block 702 is in contact with the receiving groove 5 , and an anti-skid pad is provided on the side where the two clamping blocks 702 are close to each other, and the anti-skid pad can increase the friction between the clamping block 702 and the flexible lifting door body 1 .

[0029] In this embodiment, refer to Figure 1 and Figure 2 As shown, a control module 8 is fixedly installed on the top of the connecting frame 3, and a plurality of first fixing blocks 2 are evenly distributed on both sides of the flexible lifting door body 1. The control module 8 is used to transmit and send signals to control the operation of the device.

[0030] In this embodiment, refer to Figure 2 and Figure 3 As shown, a plurality of first fixing blocks 2 are in contact with the resisting block 602 , and the resisting block 602 is designed to be arc-shaped, so that when the first fixing block 2 squeezes the resisting block 602 , the resisting block 602 can slide toward the inside of the installation slot 4 .

[0031] Working principle: When in use, firstly, all electrical equipment in the device is powered on. When the flexible lifting door body 1 is lifted, the first fixed block 2 on the flexible lifting door body 1 will resist the resistance block 602. When the flexible lifting door body 1 is operating normally, the flexible lifting door body 1 will rise and fall at a uniform speed. The first fixed block 2 will slowly compress and push the resistance block 602, thereby driving the connecting block 601 and the connecting rod 603 to slide toward the installation slot 4. Under the action of the spring 608, the connecting block 601 and the resistance block 602 will be reset;

[0032] When an emergency occurs during the operation of the flexible lifting gate body 1, causing the flexible lifting gate body 1 to fall downward, the first fixed block 2 will drop rapidly, quickly give the resistance block 602 a huge force, and rapidly push the resistance block 602, driving the connecting block 601 to be squeezed quickly. At this time, the connecting block 601 will drive the connecting rod 603 to squeeze the pressure sensor 607. When the pressure sensor 607 is squeezed, it will transmit a signal to the control module 8. The control module 8 will control the cylinder 701 to start, so that the two clamping blocks 702 pressurize and clamp the flexible lifting gate body 1, fix the flexible lifting gate body 1, and prevent the flexible lifting gate body 1 from continuing to fall.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
