Description

Technical Field

[0001] The utility model relates to the technical field of finger-pinch-proof steel door equipment, in particular to a finger-pinch-proof steel door. Background Art

[0002] In order to ensure the sturdiness of the door, it is often necessary to install steel doors in important passages for fire prevention, theft prevention and other work. The utility model patent with patent application number CN202223448436.6 discloses an anti-pinch steel door. Two air bags and two pressure plates are arranged on the support component. There is gas in the two air bags before the steel door panel is closed. If the steel door panel is closed too quickly, the rapid squeezing contact of the two pressure plates on the two air bags cannot quickly discharge the gas in the two air bags, and the two air bags will form a short-term support for the two pressure plates, thereby The steel door panel is supported, and the steel door panel cannot be closed at this time, so the person closing the door can pull his hand out in time to prevent the steel door panel and the supporting door frame from closing too quickly and causing pinching injuries to the person closing the door, thereby improving safety. According to the technical scheme disclosed by the invention, when the existing steel door with anti-pinch finger is in use, on the one hand, when the door needs to be closed quickly, it is easy to be unable to be closed smoothly due to the obstruction of the airbag, thereby avoiding the safety of personnel and property. On the other hand, when the door panel is opened, it is easy to cause the door panel to hit the wall on one side due to excessive opening force, which is not conducive to ensuring the safety of the door panel and the wall.

When the personnel needs to quickly close the door panel 2, the handle 4 is turned, and the pull wire 18 is pulled after the handle 4 is turned. The pull wire 18 pulls the bayonet 15, and the bayonet 15 compresses the spring 16 and moves from the inner side of the air hole 13 to the inner side of the inner groove 14. The two sides of the rotating plate 9 are connected to each other through the air hole 13, so that the rotating plate 9 will not be damped by the air, which is convenient for personnel to quickly close the door panel 2 in an emergency, thereby effectively protecting the safety of people and property in the room.

[0025] In this embodiment, the door panel 2 is clamped on the inner side of the door frame 1, the bearing 6 is installed at the bottom of the door frame 1, the rotating shaft 5 is welded to the bottom of the door panel 2, and the bottom of the rotating shaft 5 is installed on the inner side of the bearing 6. The slot 8 is opened on the inner side of the top of the door frame 1, and a rotating rod 7 is welded on the top of the door panel 2. The top of the rotating rod 7 extends to the inner side of the slot 8, one side of the rotating plate 9 is welded to the outer side of the rotating rod 7, and the other side of the rotating plate 9 is clamped on the inner wall of the slot 8. The ball slot 10 is opened on the inner side of the rotating plate 9, and the clamping ball 11 is clamped on the inner side of the ball slot 10. One end of the spring 12 is respectively welded on both sides of the clamping ball 11, and the other end of the spring 12 passes through the ball slot 10 and extends to the outer side of the rotating plate 9. The door lock 3 is installed on the inner side of the door panel 2 by bolts. The handle 4 is installed on the door lock 3. When opening and closing the door, the bottom of the door panel 2 rotates at the bottom of 1 through the rotating shaft 5 and the bearing 6, and the top of the door panel 2 drives the rotating plate 9 to rotate through the rotating rod 7. The air in the slot 8 circulates through the rotating plate 9 through the ball slot 10, which is convenient for the smooth opening and closing of the door panel 2. When the door panel 2 is about to be fully closed or fully opened, the spring 12 on the card ball 11 rotates to the inner wall of the card slot 8, and the spring 12 pushes the card ball 11 to one side of the ball slot 10, and then the card ball 11 is used to seal the ball slot 10, so that the air cannot circulate, and the rotating plate 9 is blocked, thereby damping the door panel 2, effectively avoiding the door panel 2 from closing or opening quickly, and effectively preventing the door panel 2 from pinching the hand or hitting the wall, thereby ensuring the safety of personnel, door panel 2 and wall.

[0026] When the anti-pinch steel door is opened and closed, the bottom of the door panel 2 rotates at the bottom of 1 through the rotating shaft 5 and the bearing 6, and the top of the door panel 2 drives the rotating plate 9 to rotate through the rotating rod 7. The air in the slot 8 flows through the rotating plate 9 through the ball slot 10, which is convenient for the smooth opening and closing of the door panel 2. When the door panel 2 is about to be completely closed or fully opened, the spring 12 on the card ball 11 rotates to the inner wall of the card slot 8, and the spring 12 pushes the card ball 11 to one side of the ball slot 10, and then the card ball 11 is used to seal the ball slot 10, so that the air cannot circulate, the rotating plate 9 is blocked, and the door panel 2 is damped. It effectively prevents the door panel 2 from closing or opening quickly, and thus effectively prevents the door panel 2 from pinching hands or hitting walls, thereby ensuring the safety of personnel, door panel 2 and walls. When personnel need to quickly close the door panel 2, they turn the handle 4, and after the handle 4 is turned, they pull the pull wire 18, and the pull wire 18 pulls the latch 15. The latch 15 compresses the spring 2 16 and moves from the inside of the air hole 13 to the inside of the inner groove 14. The two sides of the rotating plate 9 are connected to each other through the air hole 13, so that the rotating plate 9 will not be damped by the air, which is convenient for personnel to quickly close the door panel 2 in an emergency, thereby effectively ensuring the safety of personnel and property in the room.

[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
