Description

Technical Field

[0001] The utility model belongs to the technical direction of telescopic doors, and specifically relates to an anti-dumping column of an electric telescopic door. Background Art

[0002] At present, the wind-proof technology for electric telescopic doors is mainly based on laying I-beam tracks and using clips to clamp the door body. The laying of I-beam tracks consumes a lot of funds, and general companies are unwilling to spend too much money. In addition, the debris in the track must be cleaned frequently, otherwise the door will get stuck and damage the door. In addition, many doors now travel without tracks and have no resistance to strong winds. Therefore, an anti-tilt column for electric telescopic doors is proposed. When the strong wind blows the door body to tilt, one or more support points are opened for the door. By increasing the number of anti-tilt columns, multi-point support can be achieved, thereby preventing damage to the door caused by strong winds. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4The utility model provides a technical solution: an anti-dumping column of an electric telescopic door, comprising a frame 11 and a bracket 6, a tilt sensor 1 is fixed inside the frame 11, a switch power supply 2 is arranged inside the frame 11, and the tilt sensor 1 is electrically connected to the switch power supply 2;

[0021] An electromagnetic lock 3 is fixed inside the frame 11, bearings 7 are fixed on both sides of the frame 11, a connecting shaft 20 is connected to the bearing 7, a connecting rod 5 is fixed on the side of the connecting shaft 20, an upper handgrip hook 21 is fixed at the tail of the connecting rod 5, a tension spring 4 is fixed below the connecting shaft 20, and a pull-down limit screw 8 is fixed on both sides of the frame 11, and the pull-down limit screw 8 is located below the bearing 7;

[0022] The outer side of the frame 11 is threadedly connected with a nut 13, the nut 13 is threadedly connected with a bracket screw 12, the bracket 6 is located in the middle of the bracket screw 12, a fixing seat 18 is fixed inside the bracket 6, a through hole is opened on the fixing seat 18, and the connecting rod 5 is fixed at the other end to the fixing seat 18 by a bolt 19;

[0023] A fixing cylinder 14 is fixed inside the bracket 6, and the fixing cylinder 14 is located below the fixing seat 18. A round rod 10 is arranged inside the fixing cylinder 14, and a lower handshake hook 22 is fixed on the upper end of the round rod 10. The connecting rod 5 and the round rod 10 are connected by the upper handshake hook 21 and the lower handshake hook 22, and a spring 9 is sleeved on the lower end of the round rod 10;

[0025] Working principle: a certain alarm angle is set by installing the inclination sensor 1 in the frame 11. When the frame 11 of the electric telescopic door is tilted to the alarm angle of the inclination sensor 1 due to strong wind, the inclination sensor 1 will send a signal to the switch power supply 2. The switch power supply 2 will cut off the power supply of the electromagnetic lock 3 upon receiving the signal, thereby loosening the bracket 6. The connecting rod 5 will be opened under the action of the tension spring 4. When the connecting rod 5 opens to a certain angle, it will be stuck by the pull-down limit screw 8 to form a supporting angle. At the same time, the upper gripping hook 21 of the connecting rod 5 will loosen the lower gripping hook 22 of the bracket 6. At this time, the bracket 6 will bounce downward under the action of the spring 9 to support the ground. The bracket 6 will be blocked by the cylindrical pin 15 on the top to transmit the supporting force to the frame 11. The above arrangement can prevent the electric telescopic door from tipping over.
