Abstract
Description
Technical Field
[0001] This utility model belongs to the field of freezer door technology, specifically relating to a freezer door with a sealing structure. Background Technology
[0002] Freezers, also called refrigerators, are devices used to preserve food and other items at low temperatures. They come in both household and commercial types, with commercial freezers used in restaurants, bars, food processing plants, and supermarkets. The airtightness of the freezer door is a crucial factor in maintaining refrigeration efficiency. A poor seal can lead to cold air leakage, affecting refrigeration effectiveness and even increasing energy consumption. However, most existing freezers only restrict the external movement of the door, not the internal movement. This makes the freezer door susceptible to movement due to external environmental influences, further contributing to cold air leakage and limiting its effectiveness.
[0003] The existing patent, with publication number CNU, describes a mechanism where, after the cabinet door is closed, a rotating latch passes through a latch groove. Rotating the latch causes its output end to turn horizontally, thus limiting the external movement of the cabinet door. Next, two motors are activated, and their output shafts, via threaded rods, drive the latch rollers to displace, causing them to engage within an L-shaped limiting plate, thereby limiting the internal movement of the cabinet door.
[0004] However, the above solution, after limiting the external position of the cabinet door, still requires a motor drive to achieve the internal position, increasing the number of steps. Furthermore, the internal position can only be limited after the external position, further increasing the time required to seal the cabinet door, thus limiting its practical application. Utility Model Content
[0005] To address the problems existing in the background technology, this utility model provides a freezer door with a sealing structure.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A freezer door with a sealing structure includes a cabinet body. Two sealing doors are hinged to one side of the cabinet body. Each sealing door has a connecting rod at the hinge point with the cabinet body. The connecting rod is both fixedly connected to the sealing door and rotatably connected to the cabinet body. Two baffles are slidably arranged vertically inside the cabinet body. The two baffles are slidably arranged facing each other or away from each other. The baffles are in active contact with the inner side of the sealing door. The baffles are in active cooperation with the connecting rod through a transmission component.
[0008] Furthermore, a retaining plate is rotatably installed on one of the sealed doors, and a clamp is fixedly installed on the other sealed door, with the retaining plate and the clamp engaging in a locking fit.
[0009] Furthermore, the transmission component includes rotating rods, and several rotating rods are rotatably installed through the side wall of the cabinet in the vertical direction. A second gear is coaxially fixed at one end of each rotating rod, and an arc-shaped movable groove is opened on the outer surface of each rotating rod. The movable grooves are arranged in a spiral shape. Both ends of each connecting rod rotatably pass through the sealing door and are fixedly installed with a first gear. The number of first gears and second gears are equal and correspond one-to-one. Each first gear meshes with the corresponding second gear. Both ends of each baffle are fixedly installed with movable rods. The number of movable rods and movable grooves are equal and correspond one-to-one for limiting sliding cooperation.
[0010] Furthermore, each of the baffles is fixedly provided with two guide telescopic rods, the telescopic direction of which is the same as the sliding direction of the baffle, and the fixed end of the guide telescopic rod is embedded in the inner wall of the cabinet.
[0011] This application has the following beneficial effects:
[0012] 1. During the closing of the sealed door, the baffle will move automatically with the cooperation of the transmission components, thereby limiting the interior of the sealed door. This solution can limit the interior of the sealed door while limiting the exterior of the sealed door, thus simplifying the operation steps and reducing the time required for the sealed door to complete the limiting, making it more practical.
[0013] 2. The limit switch inside the sealed door can be activated during the user's closing of the sealed door. The entire process does not require a separate drive source, thereby reducing manufacturing costs and improving the overall transmission effect. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0021] like Figures 1-3 As shown, the technical solution adopted by this utility model is as follows: A freezer door with a sealing structure includes a cabinet body 1, one side of which is open. Two sealing doors 2 are hinged to the open side of the cabinet body 1, and the two sealing doors 2 rotate to block the open side of the cabinet body 1. A retaining plate 3 is rotatably installed on one of the sealing doors 2, and a clamp 4 is fixedly installed on the other sealing door 2. The retaining plate 3 and the clamp 4 are engaged and cooperated.
[0022] Each sealed door 2 is fitted with a connecting rod 5 at the hinge point between itself and the cabinet 1. The connecting rod 5 is both fixedly connected to the sealed door 2 and rotatably connected to the cabinet 1. Two baffles 11 are slidably installed facing each other in the vertical direction inside the cabinet 1. Both baffles 11 are in contact with the side of the sealed door 2 facing the cabinet 1, and the baffles 11 are connected to the connecting rod 5 through a transmission component.
[0023] The transmission components include rotating rods 7. Several rotating rods 7 are rotatably installed through the side wall of the cabinet 1 in the vertical direction. A second gear 8 is coaxially fixed at one end of each rotating rod 7. An arc-shaped movable groove 9 is opened on the outer surface of each rotating rod 7, and the movable grooves 9 are arranged in a spiral shape. Both ends of each connecting rod 5 rotatably pass through the sealing door 2 and are fixedly installed with a first gear 6. The number of first gears 6 and second gears 8 are equal and correspond one-to-one. Each first gear 6 meshes with the corresponding second gear 8.
[0024] Each baffle 11 has a fixed movable rod 10 at both ends. The number of movable rods 10 is equal to the number of movable slots 9 and they correspond one-to-one. The end of each movable rod 10 that is not connected to the baffle 11 is in a limited sliding fit with the corresponding movable slot 9.
[0025] In addition, two guide telescopic rods 12 are fixedly installed on each baffle 11. The telescopic direction of the guide telescopic rods 12 is the same as the sliding direction of the baffle 11, and the fixed end of the guide telescopic rods 12 is embedded in the inner wall of the cabinet 1.
[0026] Working principle: When in use, close the two sealing doors 2, rotate the clamp 3 so that the clamp 3 is locked in the clamp 4, thereby completing the external limiting of the sealing doors 2.
[0027] During the closing process of the sealing door 2, the sealing door 2 will drive the connecting rod 5 connected to it to rotate, thereby driving the rotating rod 7 to rotate through the meshing of the first gear 6 and the second gear 8. The rotation of the rotating rod 7 will cause the top baffle 11 to slide downward and the bottom baffle 11 to slide upward, so that the baffle 11 fits against the inside of the sealing door 2, thereby limiting the inside of the sealing door 2. Meanwhile, the movable rod 10 will slide in the movable groove 9, and the guide telescopic rod 12 will also extend.
[0028] Ultimately, by limiting the movement of the sealing door 2 inside and out, the cold air leakage caused by the sealing door 2 shaking back and forth can be prevented.
[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
