Description
Technical Field
[0001] The utility model belongs to the technical field of containers, in particular to a rolling door of a cargo container. Background Art
[0002] The rolling door of a cargo container refers to a door installed at one end or side of the container and opened or closed by rolling up. This type of door is usually composed of multiple horizontal metal or synthetic material slats, which are connected by hinges and can be rolled up or unfolded on a fixed axis. The design of the rolling door makes the door take up very little space when open, because it is only rolled up and stored above the box body, unlike traditional swing doors that open outwards and require more space. The application of rolling doors in cargo containers is mainly to provide a space-saving, convenient and fast solution for loading and unloading goods.
[0003] The rolling shutter door of the cargo container in the prior art will have a large amount of dust attached to its surface after long-term use, which will cause the dust to be easily blown up when the rolling shutter door is opened, causing dust to enter the container, affecting the cleanliness of the container and the quality of the cargo. At the same time, when the rolling shutter door fails, the motor will self-lock, but during self-locking, the weight of the rolling shutter door itself will cause a certain degree of load on the motor, affecting the life and performance stability of the motor.
[0004] To this end, we provide a rolling door for a cargo container to solve the above-mentioned problems. Utility Model Content
