Description

Technical Field

[0001] This utility model relates to the field of medical refrigerator frost-proof devices, specifically a medical refrigerator frost-proof device. Background Technology

[0002] Medical ultra-low temperature freezers are specialized refrigeration devices used in the medical field, primarily for storing biological samples, pharmaceuticals, vaccines, and other items with extremely strict temperature requirements. During use, frost will build up, and if not cleaned regularly, frost will accumulate on the inside of the outer door and in the gaps between shelves. This not only affects the freezer's cooling capacity but also makes it difficult to open or close. Currently, ultra-low temperature freezers are cleaned and maintained through periodic manual defrosting. However, manual defrosting with electrical current is time-consuming, and the rapid temperature rise may affect the quality of samples placed on the outer edges. Therefore, a frost-separating device for medical freezers is needed.

[0003] Existing medical refrigerator frost separators are inconvenient to install inside the refrigerator during use, causing the temperature of the outer sample to rise during defrosting, which affects the quality of sample storage. Therefore, there is an urgent need for a medical refrigerator frost separator. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a medical refrigerator frost barrier device to solve the problem that existing medical refrigerator frost barrier devices are inconvenient to install the frost barrier film inside the refrigerator.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a medical refrigerator frost-proof device, comprising a support column, a movable rod movably connected inside the support column, a slider fixedly connected to the outer wall of the movable rod, an anti-slip top plate fixedly connected to one end of the movable rod, and a hook fixedly connected to the outer wall of the support column.

[0006] A frost-proof membrane is fixedly connected to the outer wall of the support column. A polyurethane foam insulation layer is installed inside the frost-proof membrane, and a waterproof coating is fixedly connected to the outer wall of the frost-proof membrane.

[0007] Preferably, the support column has a slotted design, and the support column and the movable rod form a sliding structure.

[0008] Preferably, the support column and the slider form a sliding structure, and the slider is symmetrically arranged about the central axis of the movable rod.

[0009] Preferably, the other end of the movable rod is fixedly connected to a spring, and the hook is L-shaped.

[0010] Preferably, the frost-proof film is tightly bonded to the polyurethane foam insulation layer, and the frost-proof film is tightly bonded to the waterproof coating.

[0011] Preferably, the waterproof coating is arranged symmetrically with respect to the central axis of the frost barrier film, and the waterproof coating is arranged parallel to the polyurethane foam insulation layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of support columns, movable rods, anti-slip top plates and frost-proof film, allows the movable rod to slide along the support column and compress the spring by pressing the anti-slip top plates on both sides, placing the frost-proof film on the outer wall of the refrigerator door. Releasing the anti-slip top plates allows the movable rod to slide back along the support column under the action of the spring, so that the anti-slip top plates on both sides compress the inner wall of the refrigerator, which facilitates the installation and use of the frost-proof film and can remove frost covering the door to a large extent. While achieving the purpose of defrosting, it also greatly reduces the time the refrigerator door is opened, thus better ensuring the quality of samples.

[0014] 2. This utility model, through the setting of a frost-proof membrane, a polyurethane foam insulation layer and a waterproof coating, uses a polyurethane foam insulation layer fixedly connected inside the frost-proof membrane to block external heat during defrosting operations, and a waterproof coating fixedly connected to the outer wall of the frost-proof membrane to improve the waterproof performance of the frost-proof membrane.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] Please see Figure 1-4 A medical refrigerator frost-proof device includes a support column 1, a movable rod 2 movably connected inside the support column 1, a slider 3 fixedly connected to the outer wall of the movable rod 2, an anti-slip top plate 4 fixedly connected to one end of the movable rod 2, and a hook 5 fixedly connected to the outer wall of the support column 1. The support column 1 has a slotted design, and the support column 1 and the movable rod 2 form a sliding structure. The support column 1 and the slider 3 also form a sliding structure, and the slider 3 is symmetrically arranged about the central axis of the movable rod 2. A spring is fixedly connected to the other end of the movable rod 2, and the hook 5 is L-shaped, which facilitates the installation of the frost-proof film 6 on the outside of the refrigerator's inner shelf door and on the refrigerator door.

[0023] Please see Figure 1-4 A frost-proof device for a medical refrigerator includes a frost-proof membrane 6 fixedly connected to the outer wall of a support column 1, a polyurethane foam insulation layer 7 installed inside the frost-proof membrane 6, and a waterproof coating 8 fixedly connected to the outer wall of the frost-proof membrane 6. The frost-proof membrane 6 and the polyurethane foam insulation layer 7 are tightly bonded together, and the frost-proof membrane 6 and the waterproof coating 8 are also tightly bonded together. The waterproof coating 8 is symmetrically arranged about the central axis of the frost-proof membrane 6 and is arranged parallel to the polyurethane foam insulation layer 7, which can improve the heat insulation performance of the frost-proof membrane 6.

[0024] Working principle: In use, by pressing the anti-slip top plates 4 on both sides, under the guidance of the slider 3, the movable rod 2 slides along the support column 1 and squeezes the spring, placing the frost-proof film 6 on the outer wall of the refrigerator door. Releasing the anti-slip top plates 4, under the action of the spring, the movable rod 2 can slide back along the support column 1, causing the anti-slip top plates 4 on both sides to squeeze the inner wall of the refrigerator. At this time, the frost-proof film 6 blocks the sample inside the refrigerator door. When it is necessary to install the frost-proof film 6 on the refrigerator door, simply hang the hook 5 on the top of the refrigerator door. The frost-proof film 6 is fixedly connected to the inside of the polyurethane foam insulation layer 7, which can block the external heat during the defrosting operation. The frost-proof film 6 is fixedly connected to the outer wall of the frost-proof film 6, which can improve the waterproof performance of the frost-proof film 6. This completes the use of the device.
