Therefore, when a person passes under the descending roller shutter door during further use, the descending speed of the roller shutter door and the self-attaching degree are often inaccurate, so that lateral impact is generated to the bottom end of the roller shutter door, namely, the lateral impact is generated to the outer contact beam 53, the outer contact beam 53 swings by taking the rotating shaft at the top end as a fulcrum, the swinging makes the lateral lifting inclined part 53a2 of the guide groove 53a prop up to the driving pin 543 and push the driving pin 543 to move upwards through the inclined plane, the push rod 542 ascends to trigger the contact switch 551, the door closing action of the roller shutter door can be triggered to stop when the outer contact beam 5 is subjected to the lateral impact, the blocking control function of the roller shutter door is enriched, and the blocking control range is enlarged.
Moreover, the side of the guiding shell 541 adjacent to the outer contact beam 53 is provided with an outwards ejected positioning bead 544, a spring is arranged in the guiding shell 541 to eject the positioning bead 544, the positioning bead 544 has a rebound space, two positioning beads 544 are arranged at the bottom part of the side of the guiding shell 541, the side surface of the outer contact beam 53 is provided with positioning grooves 53b matched with the positioning beads 544, and when the outer contact beam 5 is subjected to upward bias, such as when the bottom edge of the outer contact beam 5 is pressed down to the edge of a human body, the contact switch 551 is triggered without rotating the outer contact beam 5, and the contact switch 551 is triggered in a vertically upward posture by the outer contact beam 5, so that a blocking object is handled in an optimal mode.
On this basis, when the back stroke range of the roller shutter door is not preset, if the back stroke range of the roller shutter door is not preset, the person continues to drill out the possible hip part and can clamp again, at this time, if further triggering is not corresponding to the control system, the outer contact beam 53 can be rotated by snapping the outer contact beam 53, when the ejector rod 542 contacts the contact switch 551 upwards, the person continues to snap, as the driven swing arm 555 is made of elastic materials, the deformation range is slightly larger than the length of the contact part of the driven swing arm 555 and the top limit edge 552a, the ejector rod 542 continues to swing upwards, the driven swing arm 555 can deform and avoid upwards, and the driven swing arm 555 and the ejector rod 542 are linked when special conditions are needed, so that the outer contact beam 53 swings in a larger range, the distance between the outer contact beam 53 and the ground is increased, and the person has a space to get rid of the person.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
