Description
Technical Field
[0001] The utility model relates to a sliding gate for a parking lot, belonging to the technical field of rolling shutter doors. Background Art
[0002] At present, the general lifting type rolling shutter device is composed of a rolling shutter door formed by connecting a plurality of slats to each other so as to be freely rotatable, a winding shaft and a guide rail. The winding shaft is installed in a rolling shutter door box arranged at the upper end of an opening such as a window or an entrance of a building, and is used to roll up the rolling shutter door. The guide rail is placed on the left and right sides of the opening of the building, and is used to guide the lifting and lowering of the rolling shutter door. In this type of lifting roller shutter door device, the roller shutter door is usually rolled up on a winding shaft in a drum shape. For example, the Chinese utility model patent with authorization announcement number CN205259908U discloses an automatic fireproof roller shutter door, and specifically discloses an end plate, a limiting roller, a roller shutter assembled from composite curtain pieces, and a driving device. The driving device is transmission-connected to the limiting roller, and guide rails are symmetrically arranged on both sides of the roller shutter to provide up and down running tracks for the roller shutter. A guide shaft is arranged obliquely below the limiting roller, and both ends of the guide shaft are respectively fixed to the end plate. The roller shutter is fixed to the limiting roller through the outer surface of the guide shaft. A thermal starter is also arranged on the limiting roller. A fireproof bag for storing a fire extinguishing agent is arranged in the outer shell of the composite curtain piece, and a plurality of nozzles connected to the fireproof bag are arranged on the outer surface of the outer shell. However, when the roller shutter of this scheme is raised or lowered, the two sides of the roller shutter slide in the guide rails, and the smoothness and synchronization are poor. In addition, after the roller shutter rises, it is wound on the limiting roller. On the one hand, the collision of the roller shutter itself is likely to produce a lot of noise when it is raised or lowered. On the other hand, the rolled-up roller shutter makes the volume of the end plate larger, which affects the height of the entrance. Utility Model Content
