[0025] Reference Figure 1-5The utility model provides an adjustable thermal insulation door, including: a door body 1, a door frame 2, a door handle 3, a locking assembly, and a driving assembly. A pin shaft 4 is fixedly installed in the middle of the door frame 2, the door frame 2 is rotatably installed on the surface of the pin shaft 4, and the door handle 3 is rotatably installed on the surface of the door body 1. The locking assembly includes a door lock and a limiting assembly. The door lock is used to achieve a tight closure of the door body 1 and the door frame 2, and the limiting assembly is used to achieve the limiting of the door frame 2 and the door body 1 after opening and closing. The driving assembly is installed in the door body 1, and the door handle 3 drives the locking assembly to operate through the driving assembly, thereby achieving the limited opening and closing of the door body 1. In this way, there is no need to use external objects to limit the door body 1. In comparison, it is more convenient to use.

[0026] The door lock includes a first protective frame 5 and a lock tongue 6. The first protective frame 5 is fixedly installed inside the door body 1, and the lock tongue 6 is slidably installed in the first protective frame 5. A through groove is opened on the side of the first protective frame 5, and the through groove penetrates into the door frame 2. At the same time, the lock tongue 6 is slidably installed in the through groove. In this way, after closing the door body 1, the lock tongue 6 will be inserted into the through groove of the door frame 2, so that the insulation door can be closed.

[0027] The limiting assembly includes a second protective frame 7 and a locking socket 8. The second protective frame 7 is fixedly installed in the door body 1, and the locking socket 8 is slidably installed in the second protective frame 7. The pin shaft 4 passes through the second protective frame 7, and the pin shaft 4 has a slot 9 on a partial surface of the second protective frame 7. The locking socket 8 can be inserted into the surface of the slot 9, and after the locking socket 8 is plugged into the slot 9, the pin shaft 4 remains fixed, thereby achieving the fixation of the door body 1.

[0028] The cross-sectional shapes of the opening portion of the locking socket 8 and the portion of the pin shaft 4 where the slot 9 is formed are both regular hexagons and have the same size, so that the locking socket 8 and the slot 9 can be easily plugged in.

[0029] The driving assembly includes a first reel 10, a first pull rope 11 and a first guide plate 12. The first reel 10 is installed in the door body 1, and the first reel 10 is fixedly installed on the rotating shaft of the door handle 3. The first pull rope 11 is wound on the surface of the first reel 10. The first guide plate 12 is slidably installed in the first protective frame 5, and the first guide plate 12 is fixed to the end of the lock tongue 6. At the same time, the end of the first pull rope 11 away from the first reel 10 penetrates into the first protective frame 5 and is fixedly connected to the first guide plate 12. In this way, rotating the door handle 3 will drive the first reel 10 to rotate, and the first reel 10 will reel in the first pull rope 11, thereby pulling the lock tongue 6 to rotate, so that the lock tongue 6 can be retracted into the door body 1. At this time, the door can be opened.

[0030] A first compression spring 13 is connected between the first guide plate 12 and the first protection frame 5, and the first compression spring 13 contacts a side of the first guide plate 12 away from the lock tongue 6. Thus, when the door handle 3 is released, the lock tongue 6 will be reset under the action of the first compression spring 13, making it convenient to close the door next time.

[0031] The driving assembly also includes a second reel 14, a second pull rope 15 and a second guide plate 16. The second reel 14 is rotatably installed in the door body 1, and the second pull rope 15 is wound on the second reel 14. The second guide plate 16 is slidably installed in the second protective frame 7, and the end of the locking socket 8 away from the pin shaft 4 is fixedly connected to the second guide plate 16. At the same time, the end of the second pull rope 15 away from the second reel 14 is fixedly connected to the second guide plate 16. A transmission assembly is connected between the first reel 10 and the second reel 14. In this way, the rotation of the door handle 3 will also drive the second reel 14 to rotate through the transmission assembly. The second reel 14 will reel up the second pull rope 15, thereby pulling the locking socket 8 to move and separate it from the slot 9, thereby releasing the limit on the door body 1. At this time, the door can be opened at will.

[0032] A second compression spring 19 is installed inside the second protective frame 7. The second compression spring 19 is installed between the second guide plate 16 and the second protective frame 7, and the second compression spring 19 contacts the side of the second guide plate 16 away from the pin shaft 4. In this way, when the door handle 3 is released, under the action of the second compression spring 19, the locking socket 8 will also be reset, thereby connecting with the slot 9, thereby completing automatic limiting.

[0033] The transmission assembly includes a first gear 17 and a second gear 18. The first gear 17 is fixedly mounted on the rotating shaft of the first reel 10, and the second gear 18 is fixedly mounted on the rotating shaft of the second reel 14. The first gear 17 is meshed with the second gear 18. At the same time, the diameter of the first gear 17 is greater than the diameter of the second gear 18. In this way, the rotation of the first reel 10 can drive the second reel 14 to rotate through the first gear 17 and the second gear 18.

[0034] Therefore, the complete usage process is that, first, turning the door handle 3 will drive the first reel 10 to rotate, and the first reel 10 will reel up the first pull rope 11, thereby pulling the lock tongue 6 to rotate, so that the lock tongue 6 is retracted into the door body 1. At the same time, the rotation of the first reel 10 will also drive the second reel 14 to rotate through the first gear 17 and the second gear 18, and the second reel 14 will reel up the second pull rope 15, thereby pulling the locking socket 8 to move and separate it from the slot 9, thereby releasing the limit on the door body 1. In this way, the door body 1 can be rotated to open it. Afterwards, when the door body 1 is opened to a suitable angle, just release the door handle 3. Under the action of the first compression spring 13, the lock tongue 6 will be reset. At the same time, under the action of the second compression spring 19, the locking socket 8 will also be reset, thereby plugging with the slot 9. At this time, the door body 1 will be limited and cannot be rotated, thereby completing the automatic limit.

[0035] In summary, during the entire use process, the door handle 3 can drive the locking assembly to operate through the driving assembly to achieve the limited opening and closing of the door body 1. During this process, you only need to release the door handle 3 at any angle of the door body 1 to automatically limit the door body 1. In this way, there is no need to use external objects to limit the door body 1. In comparison, it is more convenient to use.

[0036] At the same time, during use, after the door handle 3 is released, the door body 1 will automatically limit its position, which can prevent the user from accidentally releasing the door and being locked in the cold storage when entering a cold storage or other space that requires insulation. Relatively speaking, it is also safer to use.
