Description

Technical Field

[0001] The utility model relates to the technical field of antifreeze doors, in particular to an antifreeze door for cold storage. Background Art

[0002] Cold storage is mainly used as a constant temperature storage refrigeration equipment for food, dairy products, meat, aquatic products, etc. Cold storage is actually a low-temperature cold storage (refrigerated storage) and is also a kind of refrigeration equipment. Compared with refrigerators, its refrigeration area is much larger, but they have the same refrigeration principle.

[0003] For example, patent number CN202322201887.8 discloses a cold storage door that improves the heat preservation effect of the cold storage, including a door body that slides to cover the door, a slideway for guiding the door body to slide is provided on one side of the door body, and a windshield component that gradually spreads or gradually converges as the door body moves is provided on the side of the door body. The utility model uses a windshield component that can move and spread with the door body, so that the door body is moved away from the door and then the windshield component is used to block the door, which effectively reduces the situation where the gas in the cold storage is discharged as the cold storage door is opened, and also effectively alleviates the situation in which the windshield in the prior art is inconvenient to operate due to long-term contact with cold air;

[0004] After the cold storage door in the patent is closed, there is inevitably a certain gap between the cold storage door and the cold storage. When the cold storage door is closed for a long time, due to the poor antifreeze effect of the cold storage door, the connection between the cold storage door and the cold storage will freeze. When the user needs to open the cold storage door, it will not be able to open. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an antifreeze door for a cold storage, which solves the problem that after the cold storage door is closed, a certain gap is inevitably left between the cold storage door and the cold storage. When the cold storage door is closed for a long time, the connection between the cold storage door and the cold storage may freeze due to the poor antifreeze effect of the cold storage door. When the user needs to open the cold storage door, the door cannot be opened.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: an antifreeze door for a cold storage, comprising a displacement seat, displacement doors are provided on both sides of the bottom surface of the displacement seat, a scraper is provided at the rear end of the displacement door located below the bottom surface of the displacement seat, a connecting block is provided at the upper end of the displacement door, one side of the connecting block extends to the inner side of the displacement seat, a double-headed threaded screw is provided on one side of the connecting block located on the inner wall of the displacement seat, the double-headed threaded screw penetrates the connecting block and extends to one end of the inner wall of the displacement seat, an observation window and an armrest are respectively provided at the upper and lower ends of the front end surface of the displacement door, and a button is provided at the upper end of the armrest.

[0007] Preferably, the displacement door and the connecting block are an integrated structure, and two displacement doors are provided, wherein one side of one of the displacement doors is located on both sides of the outer surface of the other displacement door, and sealing strips are provided on the inner side of the sealing strips.

[0008] Preferably, one end of the double-threaded screw is located on the inner side of the connecting block and is provided with a threaded hole, the double-threaded screw passes through the threaded hole and extends to the other end of the inner wall of the displacement seat, and the double-threaded screw is meshed with the connecting block.

[0010] Preferably, a control chip is provided on the inner side of the button, and the button is electrically connected to the servo motor at one end of the displacement seat.

[0011] Preferably, the scraper blade is a trapezoidal inclined block, the upper end of the scraper blade is provided with absorbent cotton, and the upper end of the scraper blade is in contact with the bottom surface of the displacement seat.

[0012] Preferably, antifreeze glass is provided on the inner side of the observation window.

[0013] Beneficial Effects

[0014] The utility model provides an antifreeze door. Compared with the prior art, it has the following beneficial effects:

[0015] There are two displacement doors, one side of which is located on both sides of the outer surface of the other displacement door, and sealing strips are provided on both sides. The inner side of the sealing strips is provided with absorbent cotton. When the two displacement doors are closed, the water vapor on the inner sides of the two displacement doors is first absorbed by the absorbent cotton inside the sealing strips to prevent ice from forming inside the two displacement doors, while the sealing strips block external water vapor from entering the inner sides of the two displacement doors. Since the double-headed threaded screw and the connecting block at the upper end of the displacement door are engaged with each other, the two displacement doors perform relative displacement movement on both sides of the double-headed threaded screw during rotation, and the rear end of the displacement door is located below the bottom surface of the displacement seat and a scraper is provided. When the displacement door is displaced, the displacement door scrapes off the thin ice and icicles at the bottom end of the displacement seat from the bottom end of the displacement seat through the scraper to prevent the displacement door from being unable to open due to a thick ice layer at the bottom of the displacement seat.
