[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] See also Figure 1-Figure 4 The utility model provides a technical solution: an anti-pinch electric telescopic door, comprising: a hidden wall 1, a driver 3 and a door body 4, a door body 4 is provided on one side of the driver 3, and there are multiple door bodies 4, and a hinge rod 5 is provided between the multiple door bodies 4, and the upper and lower halves of both sides of the door body 4 are provided with fixing rings 7, and a steel wire rope 8 is provided inside the fixing ring 7, and an 8-shaped ring 9 is provided outside the steel wire rope 8 and in the area between the fixing rings 7, and a protective cloth 6 is provided between the 8-shaped rings 9 on the upper and lower sides, a main shaft 10 is provided between the hidden walls 1, and a retracting and unreeling motor 2 is provided on the outer wall of the hidden wall 1 at one end of the main shaft 10, and one end of the steel wire rope 8 is fixed to the outer wall of the main shaft 10. When the electric door is opened, the door body 4 moves toward the side close to the hidden wall 1. At this time, the reeling and winding motor 2 drives the main shaft 10 to rotate, and reels the wire rope 8. The spacing between the door bodies 4 gradually decreases, so that the distance between the fixing rings 7 on adjacent door bodies 4 is also reduced. Since the 8-shaped ring 9 close to the side of the fixing ring 7 is fixedly connected to the fixing ring 7, the protective cloth 6 between the fixing rings 7 will fold close, and will also block and protect the gap between the door bodies 4 to prevent children and the like from entering the gap between the door bodies 4, thereby achieving anti-pinch protection and improving the safety of the electric telescopic door.
[0021] Side baffles 11 are provided at both ends of the main shaft 10, an intermediate baffle 12 is provided in the middle of the main shaft 10, and one end of the wire rope 8 is located between the intermediate baffle 12 and the side baffle 11. It is convenient to separate the wire ropes 8 on both sides of the door body 4 to prevent the wire ropes 8 from being entangled with each other.
[0022] One end of the wire rope 8 away from the main shaft 10 is fixedly connected to the outer wall of the driver 3, so that when the electric door is opened or closed, one end of the wire rope 8 can move with the driver 3 to ensure that the wire rope 8 can be retracted and unreeled smoothly.
[0023] There are multiple 8-shaped rings 9, and the 8-shaped rings 9 on the side close to the fixed ring 7 are fixedly connected to the fixed ring 7, so that when the distance between adjacent fixed rings 7 changes, the protective cloth 6 between the fixed rings 7 can follow the change, while preventing the two ends of the protective cloth 6 from moving and causing the gap between the door bodies 4 to leak out, thereby ensuring the protective covering effect of the protective cloth 6.
[0024] A metal ring is provided inside the protective cloth 6 at the position where the 8-shaped ring 9 passes through, so as to improve the strength between the protective cloth 6 and the 8-shaped ring 9, increase the service life of the protective cloth 6, and prevent the protective cloth 6 from being damaged by long-term friction.
[0025] The four corners of the bottom of the driver 3 are provided with driving wheels, and the bottom two sides of the door body 4 are provided with guide wheels. The door body 4 is driven to move by the driving wheels on the driver 3, and the extension and retraction are realized by the hinge rod 5 between the door bodies 4.
[0026] When the anti-pinch electric telescopic door is in use, the door body 4 is driven to move by the driving wheel on the driver 3, and the extension and retraction are realized by the hinge rod 5 between the door bodies 4. When the telescopic door is closed, the door body 4 moves to the side away from the hidden wall 1. At this time, the wire rope 8 is unwound under tension, and the spacing between the door bodies 4 gradually increases, so that the distance between the fixing rings 7 on the adjacent door bodies 4 also increases. Since the 8-shaped ring 9 close to the fixing ring 7 is fixedly connected to the fixing ring 7, the protective cloth 6 between the fixing rings 7 is forced to open. Similarly, when the electric door is opened, The door body 4 moves toward the side close to the hidden wall 1. At this time, the reeling and winding motor 2 drives the main shaft 10 to rotate, and reels the wire rope 8. The spacing between the door bodies 4 gradually decreases, so that the distance between the fixing rings 7 on adjacent door bodies 4 is also reduced. Since the 8-shaped ring 9 close to the side of the fixing ring 7 is fixedly connected to the fixing ring 7, the protective cloth 6 between the fixing rings 7 will be folded close, and the gap between the door bodies 4 will be shielded and protected to prevent children and the like from entering the gap between the door bodies 4, thereby achieving anti-pinch protection and improving the safety of the electric telescopic door.
[0027] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
