[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5 The utility model provides a technical solution for energy-saving cold storage sliding doors. A column cavity 1.1 is provided at the axis center of the crossbeam 1, an open groove 1.2 is provided at the center of the bottom surface of the crossbeam 1 along its axial direction, a strip groove 1.3 is provided in the middle of the top surface of the inner cavity of the column cavity 1.1 along its axial direction, and a plurality of through holes 1.4 are evenly arranged on the top surface of the crossbeam 1 corresponding to the middle of the strip groove 1.3.

[0026] The door frame 2 includes a channel member 2.1 and a U-shaped member 2.2 whose bottom ends are fixed to both ends of the channel member 2.1. The top end of the U-shaped member 2.2 is fixed to both sides of the middle part of the bottom surface of the beam 1, and the front and rear sides of the top end of the U-shaped member 2.2 are respectively fixed to the front and rear sides of the opening slot 1.2.

[0027] The door panel 3 has a hollow cavity 3.2, which is open at the top and inside. Pairs of support plates 3.3 are fixed to the front and rear sides of the top of the door panel 3. The top ends of the support plates 3.3 pass through the open slots 1.2 and slide and engage with the front and rear sides of the column cavity 1.1, respectively. The front wall of the support plate 3.3 on the front of the door panel 3 is rotatably mounted with a support wheel 3.4, whose bottom end is supported on the bottom surface of the front side of the column cavity 1.1. The rear wall of the support plate 3.3 on the rear of the door panel 3 is rotatably mounted with a support wheel 3.4, whose bottom end is supported on the bottom surface of the rear side of the column cavity 1.1. To facilitate opening and closing the door panel 3 horizontally, door handles 3.1 are mounted on the front wall of the door panel 3, near the inside.

[0028] Multiple flexible baffles 4 are closely arranged horizontally. A clamping block 4.1 is fixed to the top of each flexible baffle 4 and securely engages within the strip-shaped retaining slot 1.3. A threaded hole 4.2 is located in the center of the top surface of the clamping block 4.1. The flexible baffle 4 is a flexible PVC strip. Multiple magnets 4.3 are evenly fixed vertically along the edges of the front and rear walls of the flexible baffle 4. The magnets 4.3 can also be embedded in the edges of the front and rear walls of the flexible baffle 4.

[0029] Each through hole 1.4 is fitted with a connecting bolt 5, the bottom end of which is threadedly sleeved into the corresponding threaded hole 4.2. The connecting bolt 5 is a hexagon socket bolt, and the top surface of the crossbeam 1 is provided with a circular groove 1.5 at the top of the through hole 1.4 to accommodate the end of the connecting bolt 5.

[0030] In summary, the cold storage sliding door is installed at the door opening of the cold storage, and when the door panel 3 is closed, the flexible baffle 4 is contained in the hollow cavity 3.2 of the door panel 3. When the door is opened, the door panel 3 is opened to both sides by the door handle 3.1, and the support beam 3.4 slides horizontally along the front and rear sides of the bottom of the inner cavity of the column cavity 1.1, and the bottom end of the door panel 3 slides along the groove cavity of the groove part 2.1, and the door panel 3 passes through the inner cavity of the U-shaped part 2.2. After the door panel 3 is slowly opened, the flexible baffle 4 acts as a soft door curtain structure, and the sealing state of the cold storage door opening is still maintained. After people enter and exit the door opening, the flexible baffle 4 can be quickly reset under the adsorption action of the magnet block 4.3, which greatly reduces the connection time between the inside and outside of the door opening, thereby greatly reducing the overflow of cold air, reducing energy loss, and achieving energy-saving effects.
