Detailed ways

In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

A rebound safety device in case of resistance as shown in FIGS. 1 and 2 includes a rebound controller 10 and a push rod 20 . The ejector 20 is located directly above the rebound controller 10 , more specifically, the ejector body 21 of the ejector 20 is located directly above the elastic button 15 of the rebound controller 10 .

As shown in FIG. 3 , the push rod body 21 of the push rod 20 is fixed on the door panel 30 of the rolling door through a fixing seat 22 , and the fixing seat 22 is fixedly installed on the first door panel 31 or the second door panel above the bottom beam 40 32 , the door panels 30 of the rolling door according to the present invention have elastic gaps 60 between adjacent door panels, and there are also elastic gaps 60 between the first door panel 31 and the bottom beam 40 . The main body of the rebound controller 10 is fixed on the bottom beam 40, and the magnet assembly 16 of the rebound controller 10 is fixed at the bottom position of the door post 50 close to the ground.

The bounce controller shown in FIG. 4 includes a magnetic switch connected to the rolling door control unit and a micro switch 14 connected to the rolling door control unit.

The magnetic switch shown in FIG. 4 is mainly composed of a magnet group 16 and a reed switch (not shown in the figure). The magnet assembly 16 is fixed on the bottom of the door post 50 of the rolling door, the reed switch is connected to the rolling door control unit and integrated on a circuit board 13, and the circuit board 13 is fixed in a housing 11, and the housing 11 is provided with a waterproof The sealing ring 17, the housing 11 is fixed on the bottom beam 40 of the rolling door. When the reed switch senses the magnet assembly 16, it sends a closing signal of the rolling door through the rolling door control unit. The optimum installation distance between the housing 11 and the magnet assembly 16 is within 2 centimeters. The magnet assembly 16 is installed in the position where the bottom beam 40 has not fully bottomed out, that is, the magnetism of the magnet assembly 16 should be felt earlier when the bottom beam 40 is almost at the bottom, so that the push rod 20 touches the rebound function of the micro switch 14 after invalidation. ground, when the bottom beam 40 touches the ground, there will be no rebound. When the rolling shutter door is restarted again, the rebound function can be used again when encountering resistance.

The micro switch 14 shown in FIG. 4 is connected to the rolling door control unit and integrated on the circuit board 13 .

The rebound safety device of the present invention also includes an elastic button 15 . The elastic button 15 shown in Figure 4 is a silicone button, and the silicone button corresponds to the push rod body 21 and the micro switch 14 and is arranged between the two, so that the push rod 20 touches the micro switch 14 through the silicone button, so as to Send the rising signal of the rolling door through the rolling door control unit to play the function of rebounding when encountering resistance. Specifically, when there is a foreign object blocking the bottom beam 40 to lift up, and the push rod 20 presses and touches the micro switch 14, the rolling door control unit will immediately give the rolling door control box a signal that the rolling door is going up, and the rolling door will rise immediately. , the process time is short, and it will ensure the safety of objects and personals. When being pressed, there is no need to be under too much pressure from the rolling door, and the rolling door will receive a signal to rise, so as to ensure the safety of people and property, and greatly improve the safety of the electric rolling door. . The distance between the silicone button and the push rod body 21 and the micro switch 14 is adjusted within the flexible trigger working range of the push rod 20 and the micro switch 14. The specific adjustment method may be that the door panel 30 presses the elastic gap 60 upward first. Finally, subtract 2.5-3.5mm from the position where the push rod body 21 touches the silicone button. Since the door panel 30 may not be installed in parallel, you can adjust the parallelism between the bottom surface of the push rod body 21 and the end surface of the silicone button to facilitate the push rod to touch Silicone keys. After installation, open and close the door and adjust it up and down. Whether the push rod 20 exerts too much pressure on the silicone button, or the pressure is too small and does not touch the micro switch 14, the height of the push rod body 21 can be adjusted to ensure that the present invention encounters resistance. Normal operation of the rebound safety device.

As shown in FIG. 5 , the ejector rods 20 of the present invention are arranged in two groups, and the two groups of ejector rods of the left ejector rod 20A and the right ejector rod 20B are respectively fixed on the left and right sides of the door panel 30 of the rolling door. The main part of the rebound controller 10 composed of the reed switch integrated on the circuit board 13 and the micro switch 14 is set as two groups connected, and the two groups of push rods corresponding to the left and right push rods 20A and 20B are respectively fixed on the rolling shutter door. The left and right sides of the bottom beam 40. Correspondingly, the elastic buttons 15 are correspondingly arranged in two groups, and the left elastic button 15A and the right elastic button 15B are respectively arranged corresponding to the left and right push rods 20A, 20B and the left and right micro switches.

In the working process of the resistance rebound safety device of the present invention, when the rolling shutter door encounters objects or people during its descent, the bottom beam 40 drives the rebound controller 10 composed of a reed switch integrated on the circuit board 13 and a micro switch 14 The main part of the main body and the elastic button 15 move upwards, so that the push rod 20 touches the silicone button to send a signal for the upward movement of the rolling door.
