Description

Technical Field

[0001] This utility model relates to the field of medical refrigerator technology, and more specifically to a medical refrigerator that reduces cold air leakage. Background Technology

[0002] Medical refrigerators are indispensable key equipment in the fields of medical care and scientific research, mainly used to store blood products, pharmaceuticals, vaccines, biological samples, and other items sensitive to environmental temperature. Their core function is to provide a stable and precise low-temperature preservation environment, ensuring that precious and sensitive materials maintain their original activity, efficacy, and integrity.

[0003] Application number CN202323174845.6 discloses a medical refrigerator, including a body, multiple doors, and multiple locking elements. The body includes multiple refrigeration cavities, each covered by a door. At least two doors are movably connected to locking elements. These locking elements move relative to the doors, causing adjacent locking elements to move sequentially, thus locking all doors. This application locks the doors by moving the locking elements, simultaneously moving adjacent locking elements to lock all doors together, achieving overall locking and preventing the doors from opening when the medical refrigerator is moved. It also prevents the doors from being easily opened arbitrarily, reducing accidental opening.

[0004] However, existing medical refrigerators still have a problem: when the door is opened to take out or put in items, a large amount of cold air will leak out of the refrigerator. This dynamic loss of cold air will directly affect other unused items in the refrigerator, thereby interfering with the stable low-temperature environment of these items and damaging their preservation status and internal quality. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a medical refrigerator that effectively reduces cold air leakage when the cabinet is opened, thereby ensuring the stable preservation of unused items.

[0006] This utility model adopts the following technical solution: a medical refrigerator that reduces cold air leakage, comprising: a box body and a hinged door; several partitions for dividing the box body into multiple refrigeration zones; a refrigerator box disposed in each of the refrigeration zones, with through grooves on both side walls; a linkage mechanism that extends and retracts along the depth direction within the box body through the opening and closing action of the door; and a cold-blocking mechanism disposed in the refrigeration zone and connected to the linkage mechanism; wherein, the extension and retraction movement of the linkage mechanism causes the cold-blocking mechanism to move closer to or further away from the refrigerator box, so as to clamp and close the through grooves on both sides of the refrigerator box when the door is opened, or to release the closure of the through grooves to restore the cold air passage when the door is closed.

[0007] As a preferred technical solution of this utility model, the linkage mechanism includes: a sliding plate, which is slidably disposed in the interlayer of the bottom plate of the box, with its front end exposed and magnetically connected to the box door; and a mounting bracket, which penetrates the limiting groove of the bottom plate of the box to be fixed to the sliding plate, and extends vertically upward to sequentially fix several of the partitions.

[0008] As a preferred technical solution of this utility model, the cold-blocking mechanism includes: wedges, which are respectively provided on the inner walls of both sides of the box corresponding to the two sides of the refrigerator box; a movable block, which is slidably disposed on the partition and has a wedge surface adapted to the wedges; and a clamping member, which is fixed to the inner side of the movable block and whose clamping surface completely covers the through groove on the corresponding side wall of the refrigerator box.

[0009] As a preferred technical solution of this utility model, the cooling blocking mechanism is further provided with a reset mechanism, which includes: a fixing plate, which is fixedly disposed on both sides of the end face of the partition plate, and its inner side is elastically connected to the outer side of the clamping member by a reset spring.

[0010] As a preferred technical solution of this utility model, a sliding groove is provided on the partition plate corresponding to the lower part of the moving block, and the bottom of the moving block is slidably disposed in the sliding groove by means of a pulley.

[0011] As a preferred technical solution of this utility model, a magnetic strip is provided on the lower part of the inner side of the box door, corresponding to the front end of the sliding plate.

[0012] As a preferred technical solution of this utility model, the sliding plate is provided with telescopic spring blocks on both sides near the front end. The telescopic spring blocks are used to limit and stop the sliding plate when it extends out of the interlayer to the working position.

[0013] As a preferred technical solution of this utility model, the refrigerator box is provided with a storage unit inside, and a handle is provided on the front side of the refrigerator box. The storage unit inside the refrigerator box is pulled out by the handle. The upper part of the box body is provided with a temperature control screen, and the lower part is provided with a refrigeration device.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This application incorporates a linkage mechanism and a cold-blocking mechanism. When the cabinet door is opened for item loading or unloading, the linkage mechanism drives the cold-blocking mechanism, causing the wedge surface of its moving block to interact with the wedge block on the inner wall of the cabinet. This pushes the clamping component towards the center of both sides of the refrigerator and clamps it inward, thus tightly clamping and sealing the through-slots on both sides of the refrigerator. This linkage action effectively blocks the path of cold air leakage through the through-slots, greatly reducing the loss of cold air inside the cabinet. At the same time, the telescopic spring block at the front end of the sliding plate is limited and stopped when it reaches the working position, ensuring that the cold-blocking mechanism continuously seals the through-slots. This solves the problem of a large amount of cold air leakage when the cabinet door is opened, affecting the stable low-temperature environment of other unused items. When the operation is completed and the user closes the cabinet door, the moving block of the cold-blocking mechanism automatically resets under the elastic action of the reset mechanism, releasing the clamping and sealing of the through-slots, restoring the cold air passage, and ensuring cold air circulation and temperature uniformity.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] This utility model relates to a medical refrigerator that reduces cold air leakage. Please refer to [link / reference]. Figures 1 to 4 As shown, this application aims to solve the problem of excessive cold air leakage when the door of a traditional refrigerator is opened, thereby effectively maintaining a stable low-temperature environment for the items inside the refrigerator. It includes a refrigerator body 1 and a door 2 located at the front and hinged to the body 1. The interior of the body 1 is provided with multiple layers of partitions 3, which divide the interior of the body 1 into multiple independent refrigeration zones. Each refrigeration zone contains a refrigerator box 4, and the two side walls of the refrigerator box 4 are provided with channels 5 for air circulation with the cold air inside the body 1.

[0020] To reduce cold air leakage, the refrigerator is equipped with a linkage mechanism and a cold-blocking mechanism. The linkage mechanism extends and retracts along the depth of the refrigerator body 1 when the door 2 is opened and closed. The cold-blocking mechanism is located in each refrigerator compartment and is connected to the linkage mechanism. When the linkage mechanism extends and retracts, it causes the cold-blocking mechanism to move closer to or further away from the refrigerator compartment 4: when the door 2 is open, the cold-blocking mechanism clamps and seals the through slots 5 on both sides of the refrigerator compartment 4; when the door 2 is closed, it releases the seal on the through slots 5 and restores the cold air passage.

[0021] Specifically, the linkage mechanism consists of a sliding plate 6 and a mounting bracket 8. The sliding plate 6 is slidably disposed within the interlayer inside the bottom plate 7 of the housing 1, with its front end exposed. It is connected to the door 2 via a magnetic connection. To enhance the magnetic attraction, a magnetic strip 16 is provided on the lower inner side of the door 2, corresponding to the front end of the sliding plate 6. The lower part of the mounting bracket 8 passes through the limiting groove of the bottom plate 7 of the housing 1 and is fixed to the sliding plate 6. It extends vertically upward and is sequentially fixed to several partitions 3. When the door 2 is opened, the sliding plate 6 is driven forward by the magnetic attraction, i.e., sliding outward. When the door 2 is closed, the sliding plate 6 returns to its original position with the door 2. To ensure that the sliding plate 6 can remain in the working position after being extended, telescopic spring blocks 17 are provided on both sides of the sliding plate 6 near the front end. These telescopic spring blocks 17 are used to limit and stop the sliding plate 6 when it extends out of the interlayer and reaches the working position, preventing it from automatically retracting.

[0022] The cold-blocking mechanism includes a wedge 10, a movable block 11, and a clamping member 12. Specifically, wedges 10 are respectively provided on both sides of the inner walls of the box 1, corresponding to both sides of each refrigerator box 4. A movable block 11 is slidably provided on the partition 3 of each refrigerator compartment. The movable block 11 has a wedge surface adapted to the wedge 10. A clamping member 12 is fixedly connected to the inner side of the movable block 11. The clamping surface of the clamping member 12 can completely cover the through groove 5 on the corresponding side of the refrigerator box 4. To ensure the smooth sliding and positioning of the movable block 11... On the partition 3, a groove 15 is provided below the moving block 11. The bottom of the moving block 11 is slidably disposed in the groove 15 by a pulley. At the same time, the cooling mechanism is also provided with a reset mechanism, which includes a fixed plate 13 and a reset spring 14. The fixed plate 13 is fixed to both sides of the end face of the partition 3, and its inner side is elastically connected to the outer side of the clamping member 12 by the reset spring 14, so that the clamping member 12 can be automatically pushed to reset after the linkage mechanism is released.

[0023] At the user operation level, the refrigerator box 4 has a storage unit inside, and a handle 18 is provided on the front side of the refrigerator box 4. Users can easily pull out the storage unit inside the refrigerator box 4 through the handle 18 to store and retrieve items. In addition, in order to facilitate the daily management and operation of the refrigerator box, a temperature control screen 19 is provided on the upper part of the box body 1 for displaying and adjusting the temperature, and a refrigeration device 20 is provided on the lower part to provide a cold source.

[0024] The working principle of this application is as follows: When the user needs to take items out of the refrigerator and open the door 2, the door 2 drives the sliding plate 6 of the linkage mechanism to slide forward through the magnetic attraction of the magnetic strip 16 on its inner side. The sliding of the sliding plate 6, through the mounting bracket 8 fixed to it, drives all the partitions 3 and the cold blocking mechanism on them to move forward together. During the movement of the cold blocking mechanism, the wedge surface of the moving block 11 interacts with the wedge block 10 on the inner wall of the box 1, pushing the moving block 11 towards the center of both sides of the refrigerator box 4. The clamping member 12 fixed to the moving block 11 then clamps inward, thereby tightly adhering to and clamping the through grooves 5 on both sides of the refrigerator box 4. At the same time, the telescopic spring block 17 at the front end of the sliding plate 6 is limited and stopped when it reaches the working position, ensuring that the cold blocking mechanism continues to close the through grooves 5, thereby maintaining a stable low temperature environment for items in other refrigerator areas except for the refrigerator area to be taken out.

[0025] When the operation is completed and the user closes the door 2, the door 2 will drive the sliding plate 6 to retract backward under the magnetic attraction, that is, inward. As the sliding plate 6 and the mounting bracket 8 retract, the moving block 11 of the cold blocking mechanism will automatically reset to the inside of the refrigerator box 4 under the elastic action of the reset mechanism, thereby releasing the clamping and sealing of the through slots 5 on both sides of the refrigerator box 4, restoring the cold air passage, so as to ensure cold air circulation and temperature uniformity.
