Description

Technical Field

[0001] The utility model relates to the technical field of cold storage doors, in particular to a cold storage sealing component which facilitates the opening and closing of the door. Background Art

[0002] A cold storage facility is a type of refrigeration equipment. It uses artificial means to create an environment with a different temperature or humidity than the outside. It is used to maintain a constant temperature and humidity for food, liquids, chemicals, pharmaceuticals, vaccines, scientific experiments, and other items. Cold storage facilities are typically located near shipping ports or places of origin. Compared to refrigerators, cold storage facilities have a larger cooling area and share the same refrigeration principles.

[0003] A Chinese patent (CN218407121U3) discloses a door mechanism that can enhance the sealing performance of cold storage. The servo motor drives the threaded shaft to rotate, and when the threaded shaft rotates, the movable sleeve arranged on the outside of the shaft moves and drives the door body to move left and right through the connecting vertical plate, thereby opening and closing the door. The connecting vertical plate is limited and stabilized by the reserved groove arranged in the middle position of the bottom end of the shell, thereby achieving the effect of opening or closing the door body efficiently and quickly, solving the problem of not being able to open and close the door efficiently and quickly.

[0004] However, in actual use of the above structure, when the cold storage door is in the process of reciprocating closing and opening, due to the large temperature difference between the inside and outside of the cold storage, it is easy for water droplets to form on the outer wall of the door. If the water droplets are not wiped clean in time, the low temperature of the cold storage will directly cause the water droplets to freeze, and when frozen, it is not conducive to the opening of the door, which increases the load on the motor.

[0030] The servo motor 2 is started to drive the two sets of movable switch doors 6 to open and close quickly, and at the same time, the outer wall of the movable switch door 6 can be broken into ice and wiped of moisture when the switch is closed, so as to avoid the cold storage being opened for too long, resulting in a large temperature difference with the outside, causing water droplets to form and ice on the outer wall of the movable switch door 6, making it difficult for the movable switch door 6 to open and close normally.

[0031] See also Figure 3-Figure 5 As shown, the movable switch door 6 also includes a rack 61, a first gear 62 and a first rotating rod 63; the rack 61 is opened and installed on both sides of the outside of the movable switch door 6, and four groups of racks 61 are regularly arranged; the first gear 62 is rotatably installed in the cavity of the door frame 1, and the first gear 62 and the rack 61 are arranged in the same array direction; the first rotating rod 63 is arranged between the two groups of first gears 62 in the cavity of the door frame 1.

[0032] When the movable switch door 6 moves, the rack 61 is driven to contact the first gear 62, and the first gear 62 is caused to rotate under the connection of the first rotating rod 63 provided at the bottom.

[0033] See also Figure 3-Figure 5 As shown, it includes a mounting sleeve 64 and a sponge cleaning roller 65; the mounting sleeve 64 is arranged on the upper part of the first rotating rod 63, and the mounting sleeve 64 is in the shape of a cylindrical body with an upper opening; the sponge cleaning roller 65 is arranged in the mounting sleeve 64, and its upper part is against the first rotating rod 63.

[0034] When the sponge cleaning roller 65 contacts the movable switch door 6 , it can wipe the water drops formed on the outer wall of the movable switch door 6 , so that the outer wall of the movable switch door 6 remains dry.

[0035] See also Figure 5-Figure 6As shown, it includes a second gear 66, a second transmission rod 67, scraper teeth 68 and a first silicone ring 69; the second gear 66 is rotatably installed in the cavity of the door frame 1, and its movement direction is the same as that of the rack 61; the second transmission rod 67 is installed between the second gears 66; the scraper teeth 68 are fixedly connected between the two groups of second gears 66, and the first silicone ring 69 is arranged on the side of the movable switch door 6.

[0036] The scraper teeth 68 are arranged on the front side of the sponge cleaning roller 65, so that the scraper teeth 68 first contact the movable switch door 6 and scrape off the frozen water droplets formed on the outer wall of the movable switch door 6, avoiding the movable switch door 6 being difficult to use due to the frozen water droplets.

[0037] See also Figure 6-Figure 7 As shown, it includes a mounting block 601, a telescopic spring 602 and a locking ball 603; the mounting block 601 is fixedly mounted on the lower part of the first rotating rod 63, and is colinear with the axis of the mounting sleeve 64; the telescopic spring 602 is mounted in the mounting block 601, and two telescopic springs 602 are provided; the locking ball 603 is fixedly mounted on the outside of the telescopic spring 602, and the locking ball 603 extends out of the mounting block 601.

[0038] First, open the closed door 7, and then press the two sets of locking balls 603 into the mounting block 601, so that the locking balls 603 lose their locking position on the locking slots 604 on the outside of the sponge cleaning roller 65. Then, the sponge cleaning roller 65 can be completely removed from the door frame 1, making it easier to squeeze out the water from the sponge cleaning roller 65 that has absorbed water for reuse.

[0039] See also Figure 6-Figure 7 As shown, it includes a card slot 604, an antifreeze plate 605 and a second silicone ring 606; the card slot 604 is opened on the outside of the sponge cleaning roller 65, and the position of the card slot 604 is clearance-matched with the position of the card ball 603; the antifreeze plate 605 is fixedly installed in the middle of the door frame 1, and is located between the two groups of movable switch doors 6.

[0040] The antifreeze plate 605 can be in contact with the movable switch door 6, which can prevent the contact position from freezing due to the long-term contact between the movable switch door 6 and the antifreeze plate 605. The antifreeze plate 605 can be in contact with the movable switch door 6, which can prevent the contact position from freezing due to the long-term contact between the movable switch door 6 and the antifreeze plate 605.

[0041] See also Figure 1-Figure 7 As shown, it includes a closing door 7; the closing door 7 is rotatably mounted on the outside of the door frame 1, and four groups of closing doors 7 are provided. The closing doors 7 are respectively located outside the four groups of sponge cleaning rollers 65 and scraper teeth 68.

[0042] By opening the closing door 7 , the sponge cleaning roller 65 exposed outside the door frame 1 can be replaced and the ice residue outside the scraper teeth 68 can be cleaned, thereby increasing the service life of the sponge cleaning roller 65 and the scraper teeth 68 .
