Description

Technical Field

[0001] The utility model relates to the technical field of door leaves, in particular to a combined door leaf with good resetting performance and a double-opening translation cold storage door using the combined door leaf. Background Art

[0002] A cold storage is a warehouse that uses cooling facilities to create suitable humidity and low temperature conditions. It is also called a cold storage. It is a place for processing and storing agricultural and livestock products, and it is also a major link in cold chain logistics. Since most cold storage doors in the prior art are translational door bodies, the upper end of the door body is installed on the upper guide rail assembly above the door frame in an offset suspension manner, and the lower end of the door body rolls with the lower track assembly at the bottom of the door frame through rollers, or the lower end of the door body rolls with the side guide rail assembly located on the left or right side of the lower end of the door frame through the side guide wheel bracket assembly, and the motor and sprocket assembly located on the upper guide rail assembly drives the door body to open or close in a translational manner. The problems with the sliding door body of this structure are: (1) The door leaves that make up the door body are usually made of an integrated hard door panel made of colored steel or stainless steel. Therefore, the overall weight of the door leaves is relatively large. When the door body is opened or closed at a high speed, it is difficult to stop the door leaves in time, which may cause the door leaves to be clamped or hit obstacles when closing the door; (2) Forklifts are usually used to transport items in or out of the cold storage. The ground inside the cold storage is prone to ice. When the forklift passes through the cold storage door position, if the door body is not opened in time, the forklift will slip and hit the door leaves, causing the door leaves to be severely deformed or even torn and scrapped. To this end, the utility model proposes a combined door leaf with good reset performance and a double-opening sliding cold storage door using the same, in order to solve the above technical problems. Summary of the invention

The double-opening and sliding cold storage door of the utility model has good overall rigidity, straightness and flatness of the left door leaf and the right door leaf, and the "7"-shaped hard frame ensures good tightness between the edge of the door leaf and the door frame.
