[0040] Unless otherwise specified, the functional components or structures in the following embodiments or examples are conventional components or structures used in the art to achieve the corresponding functions.

[0041] Example 1

[0042] A special refrigeration machine for medical waste, such as Figure 1-3 As shown, its specific structure is as follows:

[0043] This medical waste refrigeration unit mainly consists of a base 1 and a refrigerator 2 mounted on the base 1. The refrigerator 2 is further divided into a cabinet body 21 and a door 22. Inside the cabinet body 21, there are multiple folding storage support units for storing medical waste. Each folding storage support unit mainly consists of a support rod 3 and two support units 4 respectively located at both ends of the support rod 3, and these two support units 4 are arranged in parallel.

[0044] Each support unit 4 includes a mounting base 41, a mounting block 42, a sliding sleeve 43, and a sliding column 44. The mounting block 42 is mounted on the mounting base 41, and the sliding sleeve 43 is rotatably connected to the mounting block 42. The sliding column 44 is configured to slide along the axial direction of the sliding sleeve 43. Both ends of the support rod 3 are connected to the sliding columns 44 in the two support units 4 respectively, thus forming the main structure of the entire folding storage support unit to achieve effective support and storage of medical waste.

[0045] Example 2

[0046] A special refrigeration machine for medical waste, based on Example 1:

[0047] A mounting slot 23 is provided on the inner wall of the cabinet 21, and a fixing bolt slot 24 is provided on the mounting slot 23. A fixing bolt 25 is provided on the mounting base 41, and the fixing bolt slot 24 and the fixing bolt 25 are positioned correspondingly. The mounting base 41 is fixed in the mounting slot 23 by the cooperation of the fixing bolt slot 24 and the fixing bolt 25.

[0048] like Figure 4As shown, the mounting block 42 has a groove, and openings 421 are provided on both sides of the groove. The sliding sleeve 43 has a rotating shaft pin 431 at one end near the mounting block 42. The rotating shaft pin 431 is arranged in the radial direction of the sliding sleeve 43 and passes through the opening 421, so that the sliding sleeve 43 is rotatably connected to the mounting block 42.

[0049] The inner bottom wall of the sliding sleeve 43 is provided with sliding grooves 432 on both sides, and the sliding grooves 432 are arranged along the axial direction of the sliding sleeve 43. The bottom sides of the sliding column 44 are provided with sliders, which slide in engagement with the sliding grooves 432. The end of the sliding groove 432 away from the mounting block 42 is provided with a limiting step to prevent the sliding column 44 from slipping off.

[0050] The top of the sliding column sleeve 43 is provided with multiple limiting block grooves 433, and the sliding column 44 is provided with a guide groove along its vertical direction. The limiting block grooves 433 and the guide grooves are positioned correspondingly. A limiting block 441 is slidably arranged in the guide groove. A return spring 442 is connected to the bottom of the limiting block 441. The other end of the return spring 442 is connected to the bottom of the guide groove. The shape of the limiting block 441 and the limiting block groove 433 are adapted to lock the sliding column 44 and the sliding column sleeve 43.

[0051] The two sliding sleeves 43 have support rod clearance grooves 434 on their opposite side walls. The width of the support rod clearance grooves 434 is greater than the width of the support rod 3, which is used to accommodate the support rod 3 and ensure the stability and flexibility of the folding storage bracket unit.

[0052] In this embodiment, three folding storage support units are provided, and each folding storage support unit has three support rods to form a placement surface. The three folding storage support units are arranged in parallel and spaced apart from each other, which can better meet the storage needs of medical waste of different sizes, while optimizing the space utilization efficiency inside the refrigerator.

[0053] In actual use, this embodiment is started by connecting an external power source, and then includes the following steps:

[0054] (1) Flipping the support rod: By turning the support rod 3, the sliding sleeve 43 is flipped around the rotating shaft pin 431 until the right-angled surface of the sliding sleeve 43 is tightly fitted with the right-angled surface of the groove of the mounting block 42, so that the sliding sleeve 43 forms a 90° angle with the inner wall of the refrigerator 2. At this time, the sliding sleeve 43 is fully extended and perpendicular to the inner wall of the refrigerator, providing a stable foundation for the next sliding operation.

[0055] (2) Adjusting the position of the sliding column: Based on the specific volume of the medical waste, press the limiting block 441 to move it downwards and compress the return spring 442, causing the limiting block 441 to be pushed into the guide groove inside the sliding column 44. Then, pull the support rod 3 outwards, thereby causing the sliding column 44 to slide out from the inside of the sliding column sleeve 43 to a suitable length. During the adjustment process, multiple attempts can be made to ensure that the length of the sliding column 44 that slides out meets the storage requirements of the medical waste.

[0056] (3) Locking the position of the sliding column: When the sliding column 44 slides out to the appropriate length, under the action of the reset spring 442, the limit block 441 automatically resets and accurately locks into the corresponding limit block groove 433 at the top of the sliding column sleeve 43, thereby completing the limit operation of the sliding column 44, ensuring that the sliding column 44 will not slide accidentally during use, and providing a safety guarantee for the stable storage of medical waste.

[0057] (4) Placement of medical waste: Place the medical waste on the placement surface composed of three support rods 3 to complete the storage operation of medical waste.

[0058] In this invention, since the length and position of the support rod 9 can be flexibly adjusted according to the size of the medical waste, it can meet the storage needs of medical waste of different specifications, while also avoiding the waste of internal space of the refrigerator and significantly improving the space utilization efficiency of the refrigerator.

[0059] Example 3

[0060] A special refrigeration machine for medical waste, based on Example 2, further describes the structure of each component:

[0061] Cabinet door 22: Cabinet door 22 is an important component of the refrigeration unit, used to seal the internal space of the refrigeration unit and maintain a low temperature environment. It is connected to the refrigeration unit cabinet 21 through connecting components such as hinges, which can realize the opening and closing action. This connection method makes it convenient for operators to open and close the refrigeration unit and facilitates the storage and retrieval of medical waste.

[0062] Refrigerator 2: Refrigerator 2 is the main body of the entire device. It forms a low-temperature storage space inside for storing medical waste. Its cabinet 21 is made of heat-insulating material to reduce heat transfer and maintain a low-temperature environment. As a basic structure, the folding storage support unit is installed inside the refrigerator 2 to ensure that all components work together to complete the task of refrigerating and storing medical waste.

[0063] Support rod 3: Support rod 3 is a key support component of the folding storage rack unit. By flipping it, its position can be adjusted according to the volume of medical waste to form a placement surface of different heights and areas. The connection with the sliding column 44 allows the support rod 3 to move synchronously when adjusting the extension length of the sliding column 44, ensuring the stability of the placement surface. Its flip-up design greatly enhances the flexibility of the storage rack and can adapt to the storage needs of medical waste of different sizes.

[0064] Sliding column sleeve 43: The sliding column sleeve 43 is fitted outside the sliding column 44, serving as a guide and support. It is installed on the mounting block 13 through a specific structure and can be rotated around the rotating shaft pin 431, allowing the sliding column sleeve 43 to rotate flexibly. This, in turn, drives the connected support rod 3 and the sliding column 44 to change their angles to adapt to the storage needs of different medical wastes. When the sliding column sleeve 43 is rotated, its right-angled surface matches the inner right-angled surface of the groove opened in the mounting block 42. At this time, the sliding column sleeve 43 forms a 90° angle with the inner wall of the refrigerator 2, providing a stable foundation for the subsequent extension and retraction of the sliding column 44 and ensuring the stability of the folding storage bracket unit.

[0065] Sliding column 44: The sliding column 8 can slide inside the sliding column sleeve 43. By adjusting its extension length, it can form placement surfaces of different lengths in conjunction with the support rod 3 to adapt to the storage needs of medical waste of different volumes. The sliding connection with the sliding column sleeve 43 allows the length of the sliding column 44 to be flexibly adjusted. In actual use, the operator can easily adjust the length of the sliding column 44 sliding out from inside the sliding column sleeve 43 according to the volume of medical waste, providing suitable storage space for medical waste and improving space utilization.

[0066] Return spring 442: The top end of the return spring 442 is a rotatable spherical structure. One end of the return spring 442 is connected to the limiting block 441, and the other end is fixed at a specific position on the sliding column 43. When the limiting block 441 moves, it generates elastic deformation to provide a restoring force. The connection with the limiting block 441 and the sliding column 442 allows the return spring 442 to store elastic potential energy after the limiting block 441 is pressed. When the sliding column 44 slides out to a suitable length, the limiting block 441 is reset under the force of the return spring 442, realizing automatic locking and limiting of the position of the sliding column 44. This connection method simplifies the operation process and improves the convenience and efficiency of storage rack adjustment.

[0067] Example 4

[0068] This embodiment provides a medical waste-specific refrigerator. Several folding storage support units are installed inside the refrigerator cabinet. In use, the folding storage support units rotate around a pivot pin 431. By turning the support rod 3, the sliding sleeve 43 can be rotated. The right-angled surface of the sliding sleeve 43 can tightly fit with the right-angled surface in the groove of the mounting block 42, thus making the sliding sleeve 43 form a precise 90-degree angle with the inner wall of the refrigerator. When adjusting the folding storage support units to accommodate different sizes of medical waste, first press the limiting block 441, causing it to move downwards along the guide groove inside the sliding column 44. Simultaneously, the return spring 442 retracts, and the limiting block 441... 41 then enters the interior of the sliding column 44. At this time, the support rod 3 is pulled outward, thereby causing the sliding column 44 to slide out from the interior of the sliding column sleeve 43 to a suitable length. After the sliding column 44 slides out to the suitable length, under the action of the return spring 442, the limiting block 441 automatically resets and accurately engages in the corresponding limiting block groove 433, thereby completing the limiting operation of the sliding column 44 and ensuring that the sliding column 44 will not slide accidentally during use. This utility model not only enables the storage rack to flexibly adapt to the storage needs of various medical wastes and effectively avoids the waste of internal space of the refrigerator, but also significantly improves the overall space utilization efficiency of the refrigerator.

[0069] This utility model provides a dedicated refrigeration unit for medical waste, aiming to effectively solve the numerous problems caused by the fixed spatial layout of existing refrigeration unit storage racks after installation. In actual medical scenarios, medical waste generated by medical institutions exhibits significant diversity and fluctuation in volume, shape, and quantity. Different types of medical waste containers vary greatly in size, and traditional fixed storage racks are difficult to adapt to these containers of different specifications. When dealing with small containers, fixed storage racks result in a significant waste of space; while when storing large containers, there is often insufficient storage space. This series of problems not only reduces the utilization efficiency of the internal space of the refrigeration unit but also greatly diminishes its practicality. This utility model addresses this situation by proposing a dedicated refrigeration unit for medical waste that optimizes spatial layout and improves adaptability and practicality.

[0070] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
