[0037] Reference Figure 1-9 A high sealing door for cold storage is used for sealing cold storage to improve the sealing performance of the cold storage door and prevent the cold air in the cold storage from leaking out.
[0038] The high sealing door for cold storage comprises a door frame 1, two sliding plates 3, a door plate 4 and a plurality of fixing rods 11;
[0039] The door frame 1 is in a square shape, and the inner side of the door frame 1 is stepped, with stepped steps. The inner walls of the four sides of the door frame 1 are provided with fixing holes 2. The upper inner wall and the lower inner wall of the door frame 1 are provided with openings. A bearing plate 6 is provided at the opening. A second slide groove 601 is provided on the bearing plate 6. Each sliding plate 3 is slidably connected to a second slide groove 601. A sliding hole 602 is provided at the bottom of the second slide groove 601. A second sliding rod 302 is fixedly connected to the sliding plate 3. A limiting plate 303 is provided at one end of the second sliding rod 302. The second sliding rod 302 and the limiting plate 303 are combined into a step shape. The second sliding rod 302 passes through the sliding hole 602 and can move in the sliding hole 602, so as to facilitate the sliding plate 3 to slide into the interior of the door frame 1. The limiting plate 302 can prevent the second limiting rod 302 from falling off from the sliding hole 602 during the sliding process of the second limiting rod 302.
[0040] The door panel 4 is square in shape and is adapted to the door frame 1. The two sliding plates 3 are fixedly connected with a first sliding rod 301. The top and bottom of the door panel 4 are provided with a first sliding groove 401. The two first sliding rods 301 are respectively located in the two first sliding grooves 401, so that each first sliding rod 301 can rotate and move in the first sliding groove 401. It is rotatably connected with the two sliding plates 3, and the door panel 4 can rotate on the sliding plate 3, thereby facilitating the opening and closing of the door panel 4. When the door panel 4 is closed, the door panel 4 can be rotated first to make it parallel to the door frame 1, and then the door panel 4 can be pushed toward the inside of the door frame 1. At this time, the door panel 4 will move on the sliding plate 3, and the sliding plate 3 moves on the door frame 1, so that the two sliding plates 3 slide into the door frame 1, and the door panel 4 slides into the door frame 1. Since the door panel 4 is adapted to the door frame 1, it can be just embedded in the door frame 1. At this time, the inner side of the door panel 4 is against the stepped step of the door frame 1.
[0041] A first sealing ring 101 is provided on the stepped step of the door frame 1, a rubber strip 402 is provided on the inner side of the door panel 4, and second sealing rings 403 are provided on four sides of the door panel 4. The outer wall of the second sealing ring 403 is inclined. When the door panel 4 slides into the door frame 1, the rubber strip 402 will press against the first sealing ring 101, and at the same time, one side of the second sealing ring 403 will enter between the door frame 1 and the door panel 4. The rubber strip 402 presses against the first sealing ring 101 to perform a layer of sealing between the door frame 1 and the door panel 4, and one side of the second sealing ring 403 with an inclined outer wall will be inserted into the gap between the door frame 1 and the door panel 4 to fill the gap, so a second layer of sealing will be performed, thereby improving the sealing effect between the door frame 1 and the door panel 4.
[0042] A fixing box 7 is fixedly connected inside the door panel 4, and each side wall of the fixing box 7 is rotatably connected with a threaded cylinder 9. A threaded column 10 is threadedly connected inside each threaded cylinder 9. One end of the threaded column 10 is fixedly connected to a fixing rod 11. A driving mechanism is provided at one end of the threaded cylinder 9. The driving mechanism includes a rotating column 5 and a plurality of bevel gears 8. The rotating column 5 is rotatably connected to the fixing box 7. Each bevel gear 8 is provided at one end of the rotating column 5 and one end of a threaded cylinder 9. The bevel gear 8 located at one end of the rotating column 5 is meshed with the bevel gear 8 located at one end of the threaded cylinder 9. The other end of the rotating column 5 passes through the door panel 4 and is fixedly connected with a rotating disk 501. Four fixing sleeves 12 are fixedly connected inside the door panel 4. Four fixing rods 11 are provided, and each fixing rod 11 is slidably connected In a fixing sleeve 12, one ends of four fixing rods 11 face four side surfaces of the door panel 4 respectively, and through holes 401 are opened on the four side surfaces of the door panel 4. The rotating plate 501 can drive the rotating column 5 to rotate, thereby driving the threaded tubes 9 to rotate synchronously through the bevel gear 8. The rotation of the threaded tube 9 enables the threaded column 10 to drive the fixing rods 11 to move inside the fixing sleeve 12, so that one end of each fixing rod 11 can pass through a through hole 401 and be inserted into a fixing hole 2. Since one end of the fixing rod 11 is an inclined surface, after the inclined surface is inserted into the fixing hole 2, its inclined surface abuts against the side wall of the fixing hole 2, so that the door panel 4 is forced toward the inner side of the door frame 1, so that the door panel 4 is tightly attached to the stepped step of the door frame 1, thereby improving the sealing effect between the door frame 1 and the door panel 4.
[0043] The working principle of the high sealing door for cold storage:
[0044] When the high-sealing door needs to be closed, the door panel 4 is rotated first, and the door panel 4 is rotated on the sliding plate 3 through the first sliding rod 301, so that the door panel 4 is rotated to be parallel to the door frame 1. At this time, the door panel 4 is in a semi-closed state, and then the door panel 4 is pushed and pushed into the door frame 1. At this time, the first sliding rod 301 will slide inside the first sliding groove 401 of the door panel 4, so that the door panel 4 moves toward the inside of the door frame 1 on the sliding plate 3, and the second sliding rod 302 moves in the sliding hole 602, so that the sliding plate 3 slides on the bearing plate 6 and enters the inside of the door frame 1, so that the door panel 4 enters the inside of the door frame 1 as a whole. At this time, the rubber strip 402 on the inner side of the door panel 4 will press against the first sealing ring 101 on the stepped step of the door frame 1, so that a layer of sealing is performed between the door frame 1 and the door panel 4, and one side of the second sealing ring 403 with an inclined outer wall The second side will be inserted between the door frame 1 and the door panel 4 to fill the gap therebetween, and the second sealing ring 403 will perform a second layer of sealing. The two layers of sealing can improve the sealing effect between the door frame 1 and the door panel 4. Then, by rotating the rotating disk 501, the rotating column 5 is driven to rotate, thereby driving the threaded cylinders 9 to rotate synchronously through the bevel gear 8, so that the threaded column 10 drives the fixing rod 11 to move inside the fixing sleeve 12, so that one end of each fixing rod 11 passes through a through hole 401 and is inserted into a fixing hole 2 on the inner wall of the door frame 1. Since one end of the fixing rod 11 is an inclined surface, after the inclined surface is inserted into the fixing hole 2, its inclined surface abuts against the side wall of the fixing hole 2, so that the door panel 4 is forced toward the inner side of the door frame 1, so that the door panel 4 is tightly attached to the stepped step of the door frame 1, thereby further improving the sealing effect between the door frame 1 and the door panel 4.
[0045] When the high-sealing door needs to be opened, the rotating disk 501 is rotated in the opposite direction to move the fixed rod 11 and retract it into the door panel 4. At this time, the door panel 4 can be pulled out from the door frame 1 by pulling it outward. At this time, the first sliding rod 301 will slide inside the first sliding groove 401 of the door panel 4, and the second sliding rod 302 will move in the sliding hole 602, so that the door panel 4 is completely separated from the door frame 1. Then the door panel 4 can be rotated to be fully opened.
[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
