Description

Technical Field

[0001] This utility model relates to a refrigeration device, specifically a medical refrigerator. Background Technology

[0002] Medical cold storage boxes are devices specifically designed for storing and transporting biological products, blood samples, vaccines, and other medical supplies. These boxes are typically able to maintain the required conditions at low temperatures to ensure the safety and stability of the products.

[0003] Existing medical refrigerators, such as the portable medical refrigerator with Chinese patent publication number CN222432889U, generally include a box shell, a top cover, and a handle. The connection between the box shell, the top cover, and the handle often uses a structure that is either non-removable or has a complex disassembly process. The rotating connection between the top cover and the box shell, as well as the rotating connection between the handle and the box shell, suffers severe wear and tear due to long-term rotation and is prone to damage. When replacement is needed, it is quite inconvenient. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem of providing a medical refrigerator with a more convenient top cover and handle removal.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model for a medical refrigerator is as follows:

[0006] The device includes a box shell and a top cover rotatably connected to the box shell. A handle is rotatably connected to the top cover. It also includes a mounting component detachably connected to the rear side of the box shell. A mounting base is connected to the middle of the mounting component. A rotating shaft for inserting the top cover is inserted into the mounting base. The top cover rotates around the rotating shaft. First limiting blocks are connected to both sides of the mounting base on the rear side of the box shell. The rotating shaft is limited between the two first limiting blocks. Longitudinal insertion rods are connected to both ends of the mounting component. The two longitudinal insertion rods are respectively inserted into both sides of the box shell, and each longitudinal insertion rod has a transverse through hole in its middle. A mounting shaft is inserted into each transverse through hole. The outer end of each mounting shaft passes through the transverse through hole and is inserted into the handle. The handle is rotatably connected to the two mounting shafts.

[0007] Each longitudinal insertion rod has an insertion block connected to its front end; the box shell has insertion holes corresponding to the insertion blocks; the insertion blocks are inserted into the insertion holes corresponding to themselves, and a limiting device for limiting the insertion blocks is connected to the outside of the box shell.

[0008] The limiting device includes an outer protective sleeve, a spring, and a limiting rod; the plug-in block has a transverse insertion hole corresponding to the limiting rod; the outer protective sleeve is connected to the box shell by bolts; one end of the limiting rod passes through the plug-in hole and is inserted into the transverse insertion hole, and the other end passes through the outer protective sleeve and is exposed on the outside of the outer protective sleeve; a limiting plate is connected to the middle of the limiting rod; the spring is sleeved on the limiting rod and is limited between the limiting plate and the outer protective sleeve; the limiting rod slides laterally within the outer protective sleeve.

[0009] Each mounting shaft has a second limiting block connected to its inner end to prevent loosening.

[0010] Both ends of the mounting component have inlet and outlet holes for easy insertion of the rotating shaft.

[0011] The technical effects achieved by this utility model are as follows: When the top cover and handle of the medical refrigerator need to be removed, the mounting component can be simply pulled out of the box shell. At this time, the rotating shaft, handle, top cover, and mounting shaft can all be directly removed from the mounting component, making disassembly very convenient and replacement relatively easy. To ensure that the mounting component is fixed and stable, this utility model is also equipped with a limiting device. The mounting component is limited by the limiting device. When disassembling the mounting component, simply pull the limiting rod of the limiting device outward to disengage the limiting rod from the horizontal insertion hole on the plug block. At this time, the mounting component can be directly pulled out of the box shell. This utility model can achieve disassembly without the need for screwdrivers or other disassembly tools, making disassembly very convenient. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] See Figures 1 to 11 .

[0026] A medical refrigerator includes a box shell 1 and a top cover 2 rotatably connected to the box shell 1. A handle 3 is rotatably connected to the top cover 2. The refrigerator also includes a mounting component 10 detachably connected to the rear side of the box shell 1. A mounting base 4 is connected to the middle of the mounting component 10. A rotating shaft 5 for inserting the top cover 2 is inserted into the mounting base 4. The top cover 2 rotates around the rotating shaft 5. First limiting blocks 6 are connected to the left and right sides of the mounting base 4 on the rear side of the box shell 1. The rotating shaft 5 is limited between the two first limiting blocks 6. Specifically, both ends of the mounting component 10 are provided with inlet and outlet holes 42 for easy insertion of the rotating shaft 5.

[0027] Both ends of the mounting component 10 are connected to longitudinal insertion rods 7. The two longitudinal insertion rods 7 are respectively inserted into the two sides of the box shell 1. The middle of each longitudinal insertion rod 7 is provided with a transverse through hole 8. A mounting shaft 9 is inserted into each transverse through hole 8. The outer end of each mounting shaft 9 passes through the transverse through hole 8 and is inserted into the handle 3. The handle 3 is rotatably connected to the two mounting shafts 9. Specifically, the inner end of each mounting shaft 9 is connected to a second limiting block 41 to prevent loosening. The front end of each longitudinal insertion rod 7 is connected to an insertion block 11. The box shell 1 is provided with an insertion hole 12 corresponding to the insertion block 11. The insertion block 11 is inserted into the insertion hole 12 corresponding to itself. The outer side of the box shell 1 is connected to a limiting device for limiting the insertion block 11.

[0028] Specifically, the limiting device includes an outer protective sleeve 21, a spring 22, and a limiting rod 23. The plug-in block 11 has a transverse insertion hole 24 corresponding to the limiting rod 23. The outer protective sleeve 21 is connected to the box shell 1 by bolts. One end of the limiting rod 23 passes through the plug-in hole 12 and is inserted into the transverse insertion hole 24, while the other end passes through the outer protective sleeve 21 and is exposed on the outside of the outer protective sleeve 21. A limiting plate 25 is connected to the middle of the limiting rod 23. The spring 22 is sleeved on the limiting rod 23 and is limited between the limiting plate 25 and the outer protective sleeve 21. The limiting rod 23 slides laterally within the outer protective sleeve 21.

[0029] In this invention, the disassembly of the handle 3 and the top cover 2 is simple: first, pull the limiting rod 23 outward to disengage it from the transverse insertion hole 24 of the insertion block 11. Then, pull the mounting piece 10 backward to remove it directly from the housing 1. At this point, the rotating shaft 5, the top cover 2, the mounting shaft 9, and the handle 3 can be easily removed from the mounting piece 10. This is very convenient, and the entire process does not require disassembly tools such as screwdrivers, making it highly efficient. Installation is the reverse: first, place the top cover 2 on the mounting base 4, then insert the rotating shaft 5 into the inlet / outlet hole 42 until the rotating shaft 5 penetrates the mounting base 4 and the top cover 2 (see reference). Figure 6 , 7 Next, place the handle 3 outside the two longitudinal insertion rods 7, and insert the mounting shaft 9 into the transverse through hole 8 so that the mounting shaft 9 passes through the transverse through hole 8 and engages with the handle 3 (see reference). Figure 3 , 4 Finally, the mounting part 10 is inserted into the box shell 1 and limited by the limiting device, which makes the installation relatively convenient.
