[0029] Reference Figure 1-Figure 4 A sealing assembly for a cold storage sliding door comprises a cold storage 1, a positioning mechanism, a sealing mechanism and a locking mechanism. A connecting frame 3 is slidably provided on one side of the cold storage 1, a sliding door 4 is slidably provided on one side of the connecting frame 3, and a step groove corresponding to the door is provided on the side of the sliding door 4 close to the cold storage 1 for sealing the door;

[0030] A positioning mechanism is provided on one side of the cold storage 1 and is used to position the connecting frame 3 so that the sliding door 4 can correspond to the door after the connecting frame 3 moves;

[0031] The locking mechanism is arranged on the connecting frame 3 and is used to drive the sliding door 4 to move closer to the cold storage 1;

[0032] The sealing mechanism is arranged on the sliding door 4 and used in conjunction with the locking mechanism to further seal the sliding door 4 and the cold storage 1. By sliding the connecting frame 3 on one side of the cold storage 1 and sliding the sliding door 4 inside the connecting frame 3, a gap can be left between the sliding door 4 and the cold storage 1, which can effectively prevent the sliding door 4 from contacting the cold storage 1 during movement. In the process of movement, the connecting frame 3 can be positioned by the positioning mechanism, so that the sliding door 4 can correspond to the door, and the locking mechanism can be used to drive the sliding door 4 to approach the cold storage 1. During the approach, the sealing mechanism can be used to seal the sliding door 4 and the cold storage 1, making it easy to use.

[0033] In the utility model, the positioning mechanism includes two guide rails 2 fixedly arranged on one side of the cold storage 1, a sliding bar 17 is slidably provided in the guide rails 2, a connecting frame 3 is fixedly arranged between the two sliding bars 17 for guiding the connecting frame 3, and two limit bars 5 located on both sides of the connecting frame 3 are fixedly arranged between the two guide rails 2. Through the coordinated use of the sliding bar 17 and the guide rails 2, the connecting frame 3 can be guided during the movement of the connecting frame 3, so that its movement is more stable, and the connecting frame 3 can be limited by the two limit bars 5 to prevent the sliding bar 17 from being separated from the guide rail 2 during the movement of the connecting frame 3.

[0034] In the utility model, a limit block 8 is fixedly provided on one side of the limit strip 5 close to the door, and an insertion rod 10 is fixedly provided on one side of the limit block 8.

The fixing block 9 and one side of the connecting frame 3 are slidably penetrated with the same pin 13. A positioning hole for use with the pin 13 is opened on the outer wall of the insertion rod 10. During the movement of the connecting frame 3, the fixing block 9 can be driven to be inserted into the insertion rod 10 until the positioning hole on the insertion rod 10 corresponds to the pin 13, and the pin 13 is inserted. At this time, the insertion rod 10 can be positioned by the pin 13, so that the connecting frame 3 can be fixed.

[0035] In the utility model, the locking mechanism includes a screw rod 20 with a thread passing through it and arranged on one side of the connecting frame 3, the other end of the screw rod 20 is connected to the sliding door 4, and the first guide rod 6 is fixedly provided at the four corners of the outer side of the sliding door 4, the first guide rod 6 is slidably connected with the connecting frame 3, and the outer wall of the first guide rod 6 is sleeved with a first spring 7, and the two ends of the first spring 7 are respectively fixedly connected to the connecting frame 3 and the side of the sliding door 4 that is close to each other, and the screw rod 20 can be moved on the connecting frame 3 by rotating the screw rod 20, and the sliding door 4 can be driven to approach the cold storage 1 during the movement until one side of the sliding door 4 is completely in contact with the cold storage 1, at which time the sliding door 4 can be fixed in the door.

[0036] In the utility model, the sealing mechanism includes a first sealing strip 15 fixedly sleeved on the outer side of the sliding door 4, the first sealing strip 15 is in conflict with the inner side of the door, and is used to seal the sliding door 4 and the inside of the door, a second sealing strip 16 is fixedly provided on one side of the sliding door 4, an air bag 21 which is in communication with the second sealing strip 16 is fixedly provided on the outer side of the sliding door 4, a pressure plate 18 is fixedly provided on the outer side of the air bag 21, one end of the screw 20 is rotatably connected with the pressure plate 18, and the screw 20 is rotated to drive the pressure plate 18 to move, and the movement of the pressure plate 18 can drive the sliding door 4 to move through the air bag 21 until the sliding door 4 conflicts with the cold storage 1, and at this time, the screw 20 is continued to be rotated, which can drive the pressure plate 18 to move and compress the air bag 21, and can squeeze the gas in the air bag 21 into the second sealing strip 16, so that the second sealing strip 16 expands, and can seal between the sliding door 4 and the cold storage 1, thereby improving the sealing between the sliding door 4 and the cold storage 1.

[0037] In particular, a first channel 22 is opened in the sliding door 4, and a third channel 24 is opened on one side of the sliding door 4. One end of the third channel 24 is communicated with the airbag 21, and the other end thereof is communicated with the first channel 22. A plurality of second channels 23 are opened on the other side of the sliding door 4 that are communicated with the first channel 22, and the other end thereof is communicated with the second sealing strip 16. By setting the third channel 24, the first channel 22 and the second channel 23, the air inlet and outlet channels between the second sealing strip 16 and the airbag 21 can be increased, thereby facilitating the flow of gas in the airbag 21 and the second sealing strip 16.

[0038] In particular, a second guide rod 19 is fixedly provided on one side of the pressure plate 18, and the second guide rod 19 is slidably provided on one side of the connecting frame 3 for guiding the pressure plate 18. By arranging the second guide rod 19 on one side of the pressure plate 18 for guidance, it is possible to prevent the pressure plate 18 from rotating during the movement of the screw rod 20, and it is possible to effectively prevent the airbag 21 from twisting and being damaged.

[0039] In particular, the outer wall of the insertion rod 10 is sequentially sleeved with a second spring 12 and a limiting ring 11, the two ends of the second spring 12 are respectively fixedly connected to the mutually close side of the limiting block 8 and the limiting ring 11, and the other side of the limiting ring 11 is in conflict with the fixed block 9. The outer wall of the pin 13 is sleeved with a third spring 14, and the two ends of the third spring 14 are respectively fixedly connected to the outer side of the connecting frame 3 and the outer wall of the pin 13. In the process of the connecting frame 3 driving the fixed block 9 to move, the second spring 12 can be compressed through the limiting ring 11 until the second spring 12 is completely compressed. At this time, the positioning hole on the insertion rod 10 corresponds to the pin 13 first, and the pin 13 can be inserted into the positioning hole under the action of the third spring 14.

[0040] Working principle: When the cold storage 1 needs to be sealed, the connecting frame 3 is pushed to move, and the movement of the connecting frame 3 can drive the sliding door 4 to move to the door of the cold storage 1. During the movement, the fixing block 9 will be inserted into the insertion rod 10, and the cold storage 1 will be pushed to compress the second spring 12, and at the same time, the pin 13 will be pulled until the positioning hole on the insertion rod 10. When the pin 13 corresponds, the pin 13 is released. At this time, the pin 13 can be reset and moved under the action of the third spring 14, so that the pin 13 is inserted into the positioning hole on the insertion rod 10 to fix the connecting frame 3;

[0041] Then, the screw 20 is rotated. The rotation of the screw 20 can drive the pressure plate 18 to move. The movement of the pressure plate 18 can drive the sliding door 4 to move through the airbag 21, so that the first sealing strip 15 moves into the door until the second sealing strip 16 conflicts with the outer side of the cold storage 1. At this time, the screw 20 is continued to be rotated to drive the pressure plate 18 to move. The movement of the pressure plate 18 can compress the airbag 21, so that the air in the airbag 21 flows into the second sealing strip 16 through the third channel 24, the first channel 22 and the second channel 23, so that the second sealing strip 16 expands, and the second sealing strip 16 can be more closely in contact with the cold storage 1.

[0042] 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.
