Background

Common refrigeration house doors, whether they are folding doors or sliding doors, can be opened and closed only by occupying a folding space or a plurality of parallel tracks, and are unsafe in movable occasions. The common refrigeration house door occupies a large amount of space, and space resources are wasted in small space places such as trains, airplanes, ships and the like; the large swing of opening the refrigeration house door on the carrier running at high speed is easy to hurt people and self-damage.

The Chinese patent with the publication number of CN213116013U discloses an inner cover and outer cover coplanar sliding door device, wherein two ends of a rail are bent backwards in an arc shape, and two forked rails for backward track change are arranged in the middle of the rail; the transverse cantilever, the longitudinal cantilever and the cantilever seat are horizontally and sequentially and vertically connected into a -shaped supporting piece, and are fixed at the upper end and the lower end of one side of the back surface of the door leaf through the cantilever seat. But this patent has the following disadvantages: the distance between the sliding connection position of the -shaped support piece and the track and the cantilever seat is too large, namely the arm of force is too long when the transverse cantilever is used as a sliding support, so that the transverse cantilever is easy to damage; meanwhile, if the door leaf in the patent needs to be opened, the door leaf needs to be pulled outwards, then the door leaf is translated, the door leaf can be opened, and the door leaf is not completely translated, so that the occupied space is relatively large.

The closed type garage door occupies small space when the door is opened and closed, is safe and reliable, and can well solve the problem of space utilization rate in some compact places such as railway industry, aviation industry, ship industry and the like.
