Description

Technical Field

[0001] This utility model relates to the field of cold storage door technology, and in particular to a fireproof and heat-insulating sliding door for cold storage. Background Technology

[0002] Fireproof cold storage insulated sliding doors are specially designed for cold storage facilities. They integrate multiple functions such as fire resistance, insulation, and sliding operation, and are widely used in food processing, warehousing, pharmaceutical storage, chemical storage, and other places requiring low-temperature environments. These doors effectively isolate the external environment from temperature changes inside the cold storage, ensuring that the internal temperature is not disturbed by external factors, while also providing fire protection in the event of a fire.

[0003] Most existing fireproof cold storage insulated sliding doors only have one opening and closing method. If the opening and closing method malfunctions, it is not easy to open the door, which is inconvenient for users. Therefore, fireproof cold storage insulated sliding doors have been proposed.

[0004] A modular door assembly disclosed in announcement number CN221169229U, belonging to the field of cold storage door technology, includes a door frame. The door frame is internally connected to a door body via pins. The door body has a T-shaped movable groove and a positioning groove inside. Two sliding rods are fixedly connected to the top of the T-shaped movable groove, and a limit plate is fixedly connected to the bottom of each sliding rod. A sliding cylinder and a first spring are slidably connected to the surface of each sliding rod, with the bottom of the first spring fixedly connected to the top of the sliding cylinder. Its advantages include: by setting a rotating handle, people can twist the handle, which moves the connecting plate via a connecting rod, allowing the sound-absorbing cotton to contact the ground, reducing noise entering the door body and improving the sound insulation effect. It is easy to operate, improving the user experience. Simultaneously, the position of the cam can be limited and fixed by the spring, locking holes, and locking grooves, making it more convenient to use.

[0005] While the aforementioned patent achieves its goal of improving sound insulation by using a rotating handle that moves the connecting plate via a connecting rod, allowing the sound-absorbing cotton to contact the ground and reducing noise entering the door, thus enhancing the user experience, and providing convenient operation, it also makes it difficult to maintain the temperature inside the door or isolate mosquitoes and dust from the outside when the door is open.

[0006] Therefore, it is necessary to invent fireproof and heat-insulated sliding doors for cold storage to solve the above problems. Utility Model Content

[0040] The third step: During installation, a connecting box 1001 is threaded onto the upper surface of the back of the door frame 1. The four powerful fans 1002 inside the connecting box 1001 are activated. The high-speed rotation of the powerful fans 1002 generates an invisible air barrier, isolating the air inside and outside the storage room.
