DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, a shielding door elastic anti-pinch device includes two curtain walls 1, a shielding door 1 2 and a shielding door 2 4. The shielding door 1 2 and the shielding door 2 4 are installed on the inner side of the curtain wall 1 on the side away from each other. An alarm mechanism 7 is installed on the upper part of one of the curtain walls 1, and an anti-pinch mechanism 5 is provided on the side of the shielding door 2 4 close to the shielding door 1 2.

[0022] In this embodiment, the anti-pinch mechanism 5 includes an anti-pinch block 501, a slide groove 502 and multiple springs 503. The anti-pinch block 501 is slidably connected to the inside of the slide groove 502 on the side away from the shielding door 2. The slide groove 502 is opened on the side of the shielding door 24 close to the shielding door 2. One end of multiple springs 503 is fixedly connected to the side of the anti-pinch block 501 away from the shielding door 2. The other end of multiple springs 503 is fixedly connected to the inner wall of the slide groove 502 away from the shielding door 2. A hidden cavity 3 is provided on the side of the shielding door 2 close to the shielding door 24. The cross-sectional size of the hidden cavity 3 is larger than the cross-sectional size of the anti-pinch mechanism 5. An anti-pinch airbag 6 is provided on the periphery of the side close to the shielding door 2 and the shielding door 24. Multiple limit rods 504 are fixedly connected to the inside of the slide groove 502 away from the shielding door 2. The outer periphery of the limit rod 504 is slidably connected to the inside of the limit groove 505. The limit groove 505 is opened in the middle of the anti-pinch block 501, and the outer periphery of the limit rod 504 is arranged inside the spring 503.

[0023] Specifically, when the shielding door 1 2 and the shielding door 2 4 are closed, the anti-pinch block 501 will first touch the obstacle. Under the continuous movement of the shielding door 2 4, the anti-pinch block 501 will retract into the inside of the slide slot 502 and compress the spring 1 503 at the same time, giving people time to react and remove the obstacle. If the obstacle is not removed, the shielding door 2 4 will continue to move, so that the power connection sheet 1 701 is in contact with the power connection sheet 2 702, thereby energizing the controller 708, causing the buzzer 707 to emit a buzzing sound and the three-color light 709 to emit a flashing light, thereby reminding people, and the controller 708 will send an electrical signal to the external terminal, so that the shielding door 1 2 and the shielding door 2 4 will suspend closing. When the obstacle is removed, under the action of the spring 1 503, the anti-pinch block 501 will reset, so that the power connection sheet 1 701 and the power connection sheet 2 702 are separated, so that the shielding door 1 2 and the shielding door 2 4 continue to close, which can effectively prevent pinching.

[0024] In this embodiment, the alarm mechanism 7 includes a power connection piece 1 701, a power connection piece 2 702, a top block 703, a cavity 704, a spring 2 705 and an alarm component. The alarm component is electrically connected to the power connection piece 1 701 and an external terminal, the power connection piece 2 702 is electrically connected to an external power supply, one side of the power connection piece 1 701 is fixedly connected to the side of the anti-pinch block 501 away from the shielding door 1 2, the cavity 704 is opened in the middle of the anti-pinch block 501, and the outer periphery of the top block 703 is slidably connected to the inside of the cavity 704. Spring 2 705 is arranged inside the top block 703, and one side of the power strip 2 702 is fixedly connected to the outside of the top block 703. The alarm component includes a protection box 706, a buzzer 707, a controller 708 and a three-color light 709. The buzzer 707, the controller 708 and the three-color light 709 are installed inside the protection box 706, and the protection box 706 is installed on the upper part of the curtain wall 1. The controller 708 is electrically connected to the power strip 1 701, the external terminal, the buzzer 707 and the three-color light 709.

[0025] Working principle:

[0026] When the shielding door 1 2 and the shielding door 2 4 are closed, the anti-pinch block 501 will first touch the obstacle. Under the continuous movement of the shielding door 2 4, the anti-pinch block 501 will retract into the inside of the slide slot 502, and at the same time compress the spring 1 503, giving people time to react and remove the obstacle. If the obstacle is not removed, the shielding door 2 4 will continue to move, so that the power connection sheet 1 701 and the power connection sheet 2 702 will contact each other, thereby energizing the controller 708, causing the buzzer 707 to emit a buzzing sound and the three-color light 709 to emit a flashing light, thereby reminding people, and the controller 708 will send an electrical signal to the external terminal, so that the shielding door 1 2 and the shielding door 2 4 will suspend closing. When the obstacle is removed, under the action of the spring 1 503, the anti-pinch block 501 will reset, so that the power connection sheet 1 701 and the power connection sheet 2 702 will separate, so that the shielding door 1 2 and the shielding door 2 4 will continue to close, which can effectively prevent pinching.
