Description

Technical Field

[0001] This utility model belongs to the technical field of sliding door body equipment, specifically relating to a cold storage insulated sliding door. Background Technology

[0002] Cold storage doors are doors installed in cold storage equipment, frozen warehouses, and other refrigerated environments for insulation and airtight sealing. Cold storage doors use high-strength aluminum alloy profiles for the door frame, ensuring high strength, no deformation, a beautiful appearance, and durability. The door leaf is seamlessly welded with 2mm stainless steel edging, making it sturdy, durable, and structurally sound. The door leaf is typically molded using a polyurethane pressure injection molding machine in a single injection molding process. The polyurethane structure is dense and evenly fills the entire interior, eliminating shrinkage bubbles, resulting in a smooth and aesthetically pleasing door surface with reliable insulation performance. The door rails are made of high-strength, hard, rust-resistant aluminum alloy, featuring a floating and sinking opening system. When the door is opened, the sealing strip on the aluminum alloy door frame reduces friction; when closed, the door's own weight presses against the aluminum alloy door frame to achieve a seal. All hardware and accessories are precision-cast stainless steel, ensuring high precision, a beautiful and durable appearance, and easy, flexible, safe, and labor-saving opening and installation. TPE environmentally friendly sealing strips give cold storage doors better sealing performance and usability.

[0003] Because the sliding door body of a cold storage room is quite thick and heavy for insulation purposes, it often hits the end of the slide rail during opening. Over time, this can easily damage the slide rail, causing the sliding door body to derail and affecting its normal use. Utility Model Content
