Medical refrigerators are an important piece of equipment in the medical field. In the current medical needs, medical refrigerators are mainly used for the refrigeration, preservation and transportation of medicines, biological agents, vaccines, blood and so on. Due to different functions, there are many types of refrigerators.

[0003] Existing refrigerated boxes are equipped with doors, but most of these doors are not locked. This makes it easy for the doors to open during transportation or movement, hindering the operation of the refrigerated box and causing items inside to fall out and result in losses. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a medical refrigerator with categorizable temperature control and the advantage of a locking door. This solves the problem that existing refrigerators typically lack a locking mechanism on their external doors, making it easy for the door to open during transportation or movement, which is inconvenient for operators and causes items inside the refrigerator to fall out.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a medical refrigerator with categorizable temperature control, comprising a main body component, wherein the main body component includes:

[0008] The box body has a fixed frame fixedly connected to its front side;

[0009] The upper door is symmetrically hinged to the front side wall of the box body;

[0010] The lower door is symmetrically hinged to the front side wall of the box body;

[0011] A refrigeration mechanism is symmetrically arranged on the inner side wall of the box. A temperature regulator is arranged on the front side wall of the upper box door. The temperature regulator is electrically connected to the refrigeration mechanism. Fixing components are arranged on the fixing frame, the upper box door, and the lower box door. The fixing components include:

[0012] The cavities are symmetrically formed on the fixed frame;

[0013] A spring, one end of which is fixedly connected to the inner wall of the cavity;

[0014] A limiting block is fixedly connected to the other end of the spring, and the limiting block is slidably connected within the cavity;

[0015] A pull rod is fixedly connected to the side of the limiting block away from the box body, and a through groove is provided on the fixing frame for the pull rod to move.

[0016] Grooves are symmetrically formed on the upper and lower boxes, and the grooves correspond to the limiting blocks.

[0017] Preferably, the limiting block has an inclined surface on the side away from the box body.

[0018] Preferably, the upper compartment door and the lower compartment door are provided with a linkage mechanism, the linkage mechanism including:

[0019] A pivot is symmetrically and fixedly connected to the front side wall of the lower compartment door;

[0020] The connecting rod is rotatably connected to the rotating shaft;

[0021] A retaining ring is fixedly connected to the top of the connecting rod;

[0022] The rod is fixedly connected to the front side wall of the upper box door;

[0023] A limiting ring is fixedly connected to the front side wall of the rod.

[0024] Preferably, the inner diameter of the fixing ring is equal to the diameter of the rod, and the thickness of the fixing ring is equal to the thickness of the rod.

[0031] (III) Beneficial Effects

[0032] Compared with the prior art, this utility model provides a medical refrigerator with classifiable temperature control, which has the following beneficial effects:

[0033] This refrigerator features a locking mechanism for the doors. When securing the upper and lower doors, taking the right-side upper door as an example, the operator first pulls the lever towards the spring. The lever causes the limiting block to retract into the cavity, compressing the spring and closing the right-side upper door. Then, releasing the lever causes the spring's deformation to push the limiting block into the groove, thus restricting the upper door's movement. Similarly, the operator can operate the levers at the corresponding positions of the upper and lower doors to secure each door individually, preventing them from opening during transport. This solves the problem that existing refrigerator doors typically lack locking mechanisms, leading to easy opening during transport or movement, inconvenience for operators, and the risk of items falling out.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Example 1

[0045] See Figure 1-5 A medical refrigerator with categorizable temperature control includes a main component 1, which comprises: a box body 11 with a fixed frame 12 fixedly connected to its front side; an upper door 13 symmetrically hinged to the front side wall of the box body 11; and a lower door 14 symmetrically hinged to the front side wall of the box body 11. A refrigeration mechanism 15 is symmetrically arranged on the inner side wall of the box body 11, and a temperature regulator 151 is arranged on the front side wall of the upper door 13, the temperature regulator 151 being electrically connected to the refrigeration mechanism 15. Fixing components are provided on the fixed frame 12, the upper door 13, and the lower door 14. 2. The fixing component 2 includes: a cavity 21 symmetrically formed on the fixing frame 12; a spring 22, one end of which is fixedly connected to the inner wall of the cavity 21; a limiting block 23 fixedly connected to the other end of the spring 22, and the limiting block 23 slidably connected within the cavity 21; a pull rod 24 fixedly connected to the side of the limiting block 23 away from the box body 11, and the fixing frame 12 has a through groove for the pull rod 24 to move; and grooves 25 symmetrically formed on the upper box door 13 and the lower box door 14, the grooves 25 corresponding to the limiting block 23. The side of the limiting block 23 away from the box body 11 has an inclined surface. The upper door 13 and the lower door 14 are provided with a linkage mechanism 26. The linkage mechanism 26 includes: a rotating shaft 261, which is symmetrically and fixedly connected to the front side wall of the lower door 14; a connecting rod 262, which is rotatably connected to the rotating shaft 261; a fixing ring 263, which is fixedly connected to the top of the connecting rod 262; a rod body 264, which is fixedly connected to the front side wall of the upper door 13; and a limiting ring 265, which is fixedly connected to the front side wall of the rod body 264.

[0046] During use, the operator places medical supplies inside the cavity of the housing 11. The refrigeration mechanism 15 is used to lower the temperature inside the cavity. The temperature regulator 151 can individually adjust the temperature of the refrigeration mechanism 15 inside each cavity, facilitating the storage of medical supplies with different requirements in different cavities. When it is necessary to transport or move the housing 11, the operator uses the fixing component 2 to fix the upper door 13 and the lower door 14. Taking the upper door 13 on the right as an example, the operator first pulls the lever 24 towards the spring 22. 4. The limiting block 23 retracts into the cavity 21, compressing the spring 22. At this time, the upper box door 13 on the right side closes, and then the pull rod 24 is released. The elastic force generated by the deformation of the spring 22 pushes the limiting block 23 into the groove 25, thus restricting the upper box door 13. Similarly, the operator can operate the pull rods 24 at the corresponding positions of the upper box door 13 and the lower box door 14 to fix each upper box door 13 and lower box door 14 respectively, preventing the upper box door 13 and lower box door 14 from opening during the transportation of the box 11 and affecting the process. When it is necessary to open the upper box door 13 and lower box door 14, the corresponding pull rod 24 is pulled towards the spring 22, and the limiting block 23 disengages from the groove 25. At this time, the upper box door 13 and lower box door 14 are opened, making it easier to retrieve the items inside the box 11. The inclined surface on the limiting block 23 allows the operator to fix the upper box door 13 and the lower box door 14 without pulling the lever 24 in advance: the operator directly closes the upper box door 13 or the lower box door 14. After the upper box door 13 or the lower box door 14 contacts the inclined surface on the limiting block 23, the limiting block 23 is pushed into the cavity 21. The spring 22 is compressed, preventing the limiting block 23 from affecting the closing of the upper box door 13 or the lower box door 14. When the upper box door 13 and the lower box door 14 are completely attached to the front side of the box body 11, the limiting block 23 and the groove 25 are at the horizontal line. The spring 22 pushes the limiting block 23 into the groove 25, automatically completing the fixing of the upper box door 13 or the lower box door 14, increasing the convenience for the operator to close the upper box door 13 and the lower box door 14. When operators need to move a large number of items inside the box 11, they can use the linkage mechanism 26 to fix the upper box door 13 and the lower box door 14 on the same side into a single structure. This prevents the simultaneous opening of the four upper box doors 13 and the lower box door 14 from affecting the operator's ability to move items inside the box 11. When it is necessary to connect the upper box door 13 and the lower box door 14 on the same side, the operator can rotate the connecting rod 262 counterclockwise. The connecting rod 262 drives the fixing ring 263 to rotate until the fixing ring 263 rotates and is fitted onto the outside of the rod body 264. At this time, the connection between the upper box door 13 and the lower box door 14 on the same side is achieved, which facilitates the operator to move a large number of items.

[0047] The refrigeration principle of the aforementioned refrigeration mechanism 15 is achieved using a compressor, refrigerant, and heat transfer principles. Specifically, the compressor compresses the refrigerant into a high-pressure gas, which is then cooled into a high-pressure liquid by the condenser. Next, the high-pressure liquid is depressurized through an expansion valve, becoming a low-pressure liquid, and enters the evaporator, where it absorbs heat from the surrounding environment, causing the temperature to drop and creating a low-temperature environment. The temperature regulator 151 is specifically an electronic refrigeration mechanism 15, and the temperature of the refrigeration mechanism 15 is adjusted via a digital display and buttons. The specific connection structure between the refrigeration mechanism 15 and the temperature regulator 151 will not be described in detail here.

[0048] Example 2

[0049] An auxiliary function has been added based on Embodiment 1.

[0050] See Figure 1-5 The inner diameter of the fixing ring 263 is equal to the diameter of the rod 264, and the thickness of the fixing ring 263 is equal to the thickness of the rod 264. The limiting block 23 is provided with sliders 231 at both the top and bottom, and the cavity 21 is provided with grooves 232 at both the top and bottom, with the sliders 231 slidably connected within the grooves 232. The fixing frame 12 is provided with a limiting component 3, which includes: a plate 31 symmetrically arranged on the front sidewall of the fixing frame 12; a lead screw 32 passing through and threadedly connected to the plate 31; a limiting plate 33 rotatably connected to one end of the lead screw 32 near the pull rod 24; and a handwheel 34 fixedly connected to the other end of the lead screw 32.

[0051] The dimensions of the fixing ring 263 and the rod 264 are such that when the fixing ring 263 is fitted onto the outside of the rod 264, it cannot wobble on the rod 264, thus avoiding affecting the stability of the connection between the upper and lower doors 13 and 14 on the same side. When the limiting block 23 moves, the sliders 231 on both sides slide within the grooves 232. The sliders 231 and the grooves 232 guide the movement of the limiting block 23, increasing the stability of the limiting block 23 during movement, while preventing the limiting block 23 from dislodging from the cavity 21, facilitating timely removal or insertion into the groove 25. When the operator does not need to constantly fix the upper door 13 and the lower door 14, the operator uses the limiting component 3 to limit the pull rod 24 to prevent the limiting block 23 from protruding and causing accidental injury to the operator. When it is not necessary to fix the upper door 13 and the lower door 14, taking the upper door 13 on the right as an example, the operator pulls the pull rod 24 to the leftmost position, the limiting block 23 retracts into the cavity 21, and then rotates the handwheel 34 at the bottom, which drives the lead screw 3. 2. When the screw 32 rotates, it drives the limiting plate 33 to approach the pull rod 24 until the limiting plate 33 moves to the right side of the pull rod 24. At this time, the pull rod 24 is released, and the limiting plate 33 limits the pull rod 24 to prevent the limiting block 23 from extending out of the cavity 21. When it is necessary to fix the upper box door 13, the operator only needs to reverse the handwheel 34, the limiting plate 33 moves downward, and the spring 22 drives the pull rod 24 to automatically return to its original position, without affecting the limiting block 23's re-fixation of the upper box door 13.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
