Description

Technical Field

[0001] The utility model relates to the technical field of rolling shutter doors, in particular to a rolling shutter door with an anti-theft alarm and obstruction function. Background Art

[0002] Rolling shutters are made of multi-jointed door panels connected in series. In a fixed slide, the doors rotate up and down with the roller above the door as the center. Rolling shutters are usually widely used in shops. At present, during the closing process of rolling shutters, if there are obstacles blocking the closing of the rolling shutters, the rolling shutters will continue to move downward and close, causing damage to the rolling shutters, especially when people or cars pass by when the rolling shutters are closed, which may lead to safety accidents.

[0003] Chinese patent document CN209908372U discloses an intelligent rolling shutter door with a function of stopping when encountering obstacles, including a rolling shutter door and a guide rail, the side of the rolling shutter door is installed in the guide rail, the top of the rolling shutter door is provided with an installation box, the installation box is provided with a reel, the rolling shutter door is wound on the reel, the reel is connected to a motor, a bottom beam is provided at the bottom of the rolling shutter door, a pressure sensor is provided on the bottom beam, the pressure sensor is connected to a controller arranged in the installation box, the controller is connected to the motor, the line inlet of the motor is connected to a power supply line, a pressure relay is connected to the power supply line, and the pressure relay is connected to the pressure sensor. The above-mentioned smart rolling shutter door with the function of stopping when encountering an obstruction has shortcomings. Although the device can stop the rolling shutter door when encountering an obstruction, it has limitations. It uses an obstruction trigger line to control the lifting and lowering of the rolling shutter door. After the rolling shutter door has been used for a period of time, deformation will occur between the door panels, and the deformation directly affects the tightness of the obstruction trigger line, which in turn directly causes the rolling shutter door to be unable to descend.

[0022] Reference Figure 1-4 The utility model provides an embodiment: a rolling shutter door with an anti-theft alarm and an obstruction function, comprising a base 1, a servo motor 11 is fixedly connected to the inner bottom wall of the base 1, a connecting column 12 is fixedly connected to the output end of the servo motor 11, an end of the connecting column 12 away from the servo motor 11 is rotatably connected to the inner side wall of the base 1, a reel 13 is fixedly connected to the side wall of the connecting column 12, a guide rail 14 is fixedly connected to the lower end of the base 1, a controller 15 is arranged on the inner side wall of the base 1 away from the servo motor 11, an alarm 16 is arranged on the inner side wall of the base 1, and the alarm 16 and the controller 15 are located on the same inner side wall of the base 1, a rolling shutter door body 2 is arranged on the outer side wall of the reel 13, and one end of the rolling shutter door body 2 is fixedly connected to the side wall of the reel 13 The other end of the rolling door body 2 is fixedly connected to the mounting plate 21, and the rolling door body 2 is installed in the guide rail 14. The lower end of the mounting plate 21 is fixedly connected with a mounting seat 22. The end of the mounting seat 22 away from the mounting plate 21 is provided with a mounting groove 221. A push plate 223 is arranged inside the mounting seat 22. The push plate 223 is located in the mounting groove 221, and the push plate 223 is slidably connected to the mounting groove 221. A pressure sensor 224 is arranged on the upper end of the push plate 223. A push block 225 is fixedly connected to the end of the push plate 223 away from the pressure sensor 224. The pressure sensor 224 is electrically connected to the servo motor 11 through the controller 15, and the pressure sensor 224 is electrically connected to the alarm 16 through the controller 15.

[0023] In this arrangement, when the rolling door body 2 encounters resistance during descent, the push block 225 pushes the push plate 223 to slide vertically in the installation groove 221, so that the push plate 223 pushes the pressure sensor 224 to squeeze the top wall inside the installation groove 221, and then the pressure sensor 224 transmits the detected pressure to the controller 15, and then the controller 15 outputs an electrical signal to control the servo motor 11 to stop rotating, and then controls the rolling door body 2 to stop moving downward, and then the controller 15 outputs an electrical signal to control the alarm 16, so that the alarm 16 is activated and an alarm sound is sounded, so as to raise attention and remove obstacles in time to avoid damage to the rolling door body 2, and at the same time avoid personal injury or property loss.
