Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration equipment, and particularly relates to a cold storage door insulation device. Background Art

[0002] A cold storage facility, also a type of refrigeration equipment, uses artificial means to create an environment with a temperature or humidity that differs from the outside. This allows for the constant storage of food, liquids, chemicals, pharmaceuticals, vaccines, scientific experiments, and other items at a constant temperature and humidity. Cold storage facilities are typically located near shipping ports or places of origin. While they share the same refrigeration principles as refrigerators, they cover a larger area. A cold storage door is a door installed in a cold storage facility to insulate and seal the contents, significantly, and even decisively, impacting its storage performance.

[0003] The cold storage sealing plate is an important component when entering and exiting the cold storage. The existing cold storage sealing plate is a foam sandwich panel. This cold storage sealing plate cannot be disassembled or replaced, and has poor applicability. When the temperature in the cold storage needs to be changed, it may lead to insufficient insulation effect of the cold storage and cannot effectively isolate the external heat, thereby affecting the refrigeration effect of the cold storage. Utility Model Content

[0006] A cavity is provided in the insulation board, and two racks are movably connected in the cavity of the insulation board. A guide plate is fixed to an outer wall of one side of the rack, and two positioning columns are fixed to an outer wall of a side of the guide plate away from the rack.

[0007] In a further embodiment, a rotating column extending to the outside of the insulation board is rotatably connected in the cavity of the insulation board, and a gear meshing with the rack is fixed to the outer wall of the rotating column.

[0008] In a further embodiment, a turntable is fixed to the end surface of the rotating column located outside the insulation board, a threaded hole is opened on the turntable, and a fixing bolt is threadedly connected in the threaded hole of the turntable.

[0009] In a further embodiment, an electric plug is installed on the inner wall of the cold storage door panel, and a socket matching the electric plug is opened on one side of the outer wall of the heating sleeve.

[0010] In a further embodiment, rotation grooves are provided on both side outer walls of the guide plate, and limiting balls are rotatably connected in the rotation grooves of the guide plate.

[0011] In a further embodiment, the upper and lower inner walls of the cold storage door panel are provided with positioning holes matching the positioning columns, and the inner walls on both sides of the insulation board are provided with two limiting sliding grooves for the limiting balls to slide.

[0012] The technical effects and advantages of this utility model are:

[0013] The cold storage door insulation device uses a detachable insulation board. When the refrigeration temperature in the cold storage changes, the insulation board can be quickly removed from the cold storage door panel and the insulation board in the heating sleeve can be replaced, thereby meeting different refrigeration needs. It is flexible to use and ensures the refrigeration effect of the cold storage.

[0014] By setting the electric heating tube in the heating sleeve, when the cold storage door panel is closed for a long time and the connection between the cold storage door panel and the cold storage is frozen, the cold storage door panel can be heated to quickly thaw the frozen position, thereby avoiding the situation where the connection between the cold storage door panel and the cold storage cannot be opened due to freezing;

[0015] The gear is driven to rotate by the rotating column, thereby driving the rack and the guide plate to move, so that the positioning column is inserted into the positioning hole of the cold storage door panel, which can ensure the stability of the connection between the cold storage door panel and the insulation panel. The cold storage door insulation device is convenient for replacing the insulation panel according to the refrigeration needs of the cold storage, and can avoid freezing at the connection between the cold storage door panel and the cold storage.

[0030] Working principle:

[0031] When the cold storage door insulation device is used, the cold storage door panel 1 is installed on the cold storage. When the cold storage door panel 1 is closed for a long time and the connection between the cold storage door panel 1 and the cold storage is frozen, the electric heating tube 5 is started to heat the cold storage door panel 1, so that the frozen position is quickly thawed, thereby opening the cold storage door panel 1;

[0032] When the temperature in the cold storage needs to be adjusted and the insulation board 6 needs to be replaced, loosen the fixing bolt 10, drive the rotating column 7 and the gear 8 to rotate through the turntable 9, and the gear 8 drives the two racks 11 to move toward each other, thereby driving the two guide plates 12 to move toward each other, so that the positioning column 13 retracts into the insulation board 3, removes the insulation board 3 from the cold storage door panel 1, and then removes the insulation board 6 from the heating sleeve 4, replaces the appropriate insulation board 6, and after the insulation board 6 is replaced, put the insulation board 3 back into the cold storage door panel 1, rotate the turntable 9 in the opposite direction, drive the two guide plates 12 to move in opposite directions, so that the positioning column 13 is inserted into the positioning hole of the cold storage door panel 1, ensure the stability of the connection between the cold storage door panel 1 and the insulation board 3, and then tighten the fixing bolt 10 to make it close to the outer wall of the insulation board 3, thereby fixing the position of the turntable 9 to prevent the turntable 9 from rotating accidentally.
