The shelf plates are adjusted and locked by bolts passing through locking holes in the shelf plates and threadedly connected to the threaded holes on the same horizontal plane. This type of antioxidant freezer has some problems. For example, the adjustment process is relatively slow because the bolts are connected to the corresponding threaded holes. The bolts need to be turned back and forth multiple times to adjust and lock the shelf plates. This makes it inconvenient for personnel to quickly and stably adjust the shelf plates and increases the workload of personnel. Utility Model Content

Sliding grooves are provided at the ends of the two front guide posts furthest from the center of the freezer compartment. Locking blocks are fixedly connected to the upper ends of the inner walls of the rotating cylinders, and the locking blocks are slidably connected to the annular grooves located on the same horizontal plane. This mechanism enables quick and stable height adjustment of the shelf panels, effectively meeting the storage needs of frozen dumplings and frozen rice balls of different capacities. It also makes shelf panel position adjustment more convenient and reduces the workload of personnel.
[0007] Furthermore, the adjustment mechanism also includes brackets and torsion springs. The brackets are fixedly connected to the four corners of the upper surface of the shelf, and the upper ends of the brackets are slidably connected to the outer surfaces of the adjacent guide columns. Torsion springs are fixedly connected between the upper end of the rotating cylinder and the top wall of the vertically adjacent brackets. The torsion springs are movably sleeved on the outer surfaces of the adjacent guide columns to ensure the stability of the shelf's position locking.
[0008] Furthermore, a PLC controller is installed at the front end of the left side surface of the freezer. The input terminal of the PLC controller is electrically connected to an external power supply to control various electrical appliances.

[0010] Furthermore, temperature sensors are evenly distributed on the inner walls of both sides of the freezer compartment. These temperature sensors are bidirectionally electrically connected to the PLC controller to monitor the temperature inside the freezer compartment.
[0011] Furthermore, a fan trough is provided at the rear end of the freezer, which is connected to the electrical compartment. A fan is installed inside the fan trough, and the input end of the fan is electrically connected to the output end of the PLC controller to realize heat dissipation of the refrigeration equipment.
[0012] Furthermore, the front end of the freezer compartment is hinged with symmetrically distributed cabinet doors, and the rear end of the electrical compartment is bolted with a cover, which facilitates equipment maintenance and the storage and retrieval of frozen dumplings and rice balls.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This antioxidant freezer has the following advantages:

Detailed Implementation
[0022] 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.
[0023] Please see Figure 1-6 This embodiment provides a technical solution: an antioxidant freezer, including a freezer cabinet 1, a freezer compartment 2 at the front end of the freezer cabinet 1, an electrical compartment 3 at the rear end of the freezer cabinet 1, a PLC controller 13 at the front end of the left side surface of the freezer cabinet 1, the input terminal of the PLC controller 13 being electrically connected to an external power supply, and also including an adjustment mechanism 4;
[0024] Adjustment mechanism 4 includes guide posts 41, fixed cylinders 42, rotating cylinders 43, annular grooves 44, sliding grooves 45, and locking blocks 46. The guide posts 41 are fixedly connected to the four corners inside the freezer compartment 2. Evenly distributed shelf plates 5 (each shelf plate 5 has evenly distributed through holes) are slidably connected inside the freezer compartment 2. Each shelf plate 5 has a sliding opening at one of its four corners, and the interior of each sliding opening is slidably connected to the outer surface of the adjacent guide post 41. The upper ends of the two sliding openings on the front side of the shelf plate 5 are fixedly connected to fixed cylinders 42, and the outer surfaces of the fixed cylinders 42 are slidably connected to the inner walls of the vertically adjacent rotating cylinders 43. The lower end is rotatably connected. The two guide pillars 41 on the front side each have evenly distributed annular grooves 44 in their middle sections. The ends of the two guide pillars 41 on the front side away from the center of the freezer compartment 2 each have sliding grooves 45. A locking block 46 is fixedly connected to the upper end of the inner wall of the rotating cylinder 43. The locking blocks 46 are slidably connected to the annular grooves 44 located on the same horizontal plane. The adjustment mechanism 4 also includes a bracket 47 and a torsion spring 48. The brackets 47 are fixedly connected to the four corners of the upper surface of the shelf 5. The upper ends of the brackets 47 are slidably connected to the outer surfaces of adjacent guide pillars 41. The upper end of the rotating cylinder 43 and the top of the vertically adjacent brackets 47 are connected... Torsion springs 48 are fixedly connected between the walls. These torsion springs 48 are movably sleeved on the outer surface of adjacent guide posts 41. Depending on the quantity of dumplings and rice balls to be stored, the rotating cylinder 43 rotates counterclockwise. Each rotating cylinder 43 rotates around the central axis of its corresponding fixed cylinder 42. The rotation of the rotating cylinder 43 drives the adjacent locking blocks 46 to rotate. The locking blocks 46 slide laterally within their corresponding annular grooves 44. When the locking blocks 46 are fully inserted into the sliding groove 45, the torsion springs 48, due to the torsional force of the rotating cylinder 43, restrain the position of the rotating cylinder 43. Then, the storage plate 5 slides vertically, causing the storage plate 5 to... Slide vertically between the four guide posts 41. When the shelf 5 reaches the desired position, the limiting of the rotating cylinder 43 ends. The rotating cylinder 43 rotates clockwise under the elastic force of the vertically adjacent torsion springs 48. The reverse rotation of the rotating cylinder 43 drives the corresponding locking block 46 to rotate in the opposite direction. The locking blocks 46 slide counterclockwise inside the annular groove 44 on the same horizontal plane. The locking blocks 46 leave the slide groove 45. The annular groove 44 locks the position of the locking blocks 46, thereby locking the position of the shelf 5. After the shelf 5 is adjusted, place the dumplings and rice balls to be frozen on the top of the shelf 5.
[0025] The following configuration is provided: a compressor 6 is installed on the bottom wall of the electrical compartment 3; a condenser 7 is installed in the middle of the front inner wall of the electrical compartment 3; an evaporator 8 is installed on the rear inner wall of the freezer compartment 2; the liquid outlet of the evaporator 8 is connected to the liquid inlet of the compressor 6 via an external water pipe; the liquid inlet of the condenser 7 is connected to the liquid outlet of the compressor 6 via an external water pipe; the liquid outlet of the condenser 7 is connected to the liquid inlet of the evaporator 8 via an external water pipe; the input terminal of the compressor 6 is electrically connected to the output terminal of the PLC controller 13; and temperature sensors 9 are evenly distributed on both the left and right inner walls of the freezer compartment 2. The temperature sensors 9 are all connected to... The PLC controller 13 has a bidirectional electrical connection. A fan slot is located at the rear of the freezer 1, connecting to the electrical compartment 3. A fan 10 is installed inside the fan slot, and its input is electrically connected to the output of the PLC controller 13. Symmetrically distributed cabinet doors 12 are hinged to the front of the freezer compartment 2. A compartment cover 11 is bolted to the rear of the electrical compartment 3. The PLC controller 13 controls the operation of the compressor 6. The compressor 6 draws in low-temperature, low-pressure gaseous refrigerant from the evaporator 8 through an external water pipe and compresses it into a high-temperature, high-pressure gas through mechanical work, increasing the refrigerant's energy. Compressor 6 pushes high-temperature, high-pressure gaseous refrigerant into the condenser 7 through external water pipe 2. There, it exchanges heat with a cooling medium (such as air or water), releasing heat and condensing into a high-pressure liquid state, thus liquefying it. The low-temperature, low-pressure liquid and gaseous refrigerant mix enters the evaporator 8, absorbing heat from the dumplings and rice balls and evaporating, lowering their temperature and achieving a cooling effect. The refrigerant is then drawn back into compressor 6, and the cycle repeats, achieving both cooling and anti-oxidation freezing of the dumplings and rice balls. Simultaneously, PLC controller 13 operates fan 10, which facilitates air exchange between the inside and outside of the electrical compartment 3, providing cooling for the condenser. 7 provides fresh cooling medium and heats up the compressor 6. At the same time, the PLC controller 13 enables the operation of the temperature sensor 9. When the internal temperature of the freezer compartment 2 changes, the resistance of the thermistor of the temperature sensor 9 will change accordingly. By measuring the change in the resistance of the thermistor and converting it into an electrical signal (such as a voltage or current signal), the temperature information of a specified area inside the freezer compartment 2 can be obtained. The temperature sensor 9 sends the temperature information to the signal receiving end of the PLC controller 13 in real time. The PLC controller 13 adjusts the operating status of the compressor 6 according to the collected temperature information.
[0026] The working principle of the antioxidant freezer provided by this utility model is as follows: During operation, the operator first places the freezer 1, freezer compartment 2, and other mechanisms stably in a horizontal working area. Then, based on the required quantity of dumplings and rice balls to be stored, the operator simultaneously rotates the rotating drum 43 counterclockwise. The rotating drum 43 rotates around the central axis of the corresponding fixed drum 42. The rotation of the rotating drum 43 drives the adjacent locking blocks 46 to rotate. The locking blocks 46 slide laterally within their corresponding annular grooves 44. When the locking blocks 46 are fully inserted into the sliding groove 45, the torsion spring 48, due to the torsional force of the rotating drum 43, allows the operator to hold and restrict the position of the rotating drum 43. Then, the operator vertically slides the shelf 5, causing the shelf 5 to... All slide vertically between the four guide posts 41. When the shelf 5 reaches the desired position, the operator releases the limiting force on the rotating drum 43. The rotating drum 43 rotates clockwise under the elastic force of the vertically adjacent torsion springs 48. The reverse rotation of the rotating drum 43 drives the corresponding locking block 46 to rotate in the opposite direction. The locking block 46 slides counterclockwise inside the annular groove 44 on the same horizontal plane. The locking block 46 leaves the slide groove 45, and the annular groove 44 locks the position of the locking block 46, thereby locking the position of the shelf 5. After the shelf 5 is adjusted, the operator places the dumplings and rice balls to be frozen on the top of the shelf 5, then closes the cabinet door 12, and then the PLC controller 13 activates the compressor. 6. During operation, compressor 6 draws in low-temperature, low-pressure gaseous refrigerant from evaporator 8 through external water pipe 1. Through mechanical work, it compresses the refrigerant into a high-temperature, high-pressure gas, increasing its energy. Then, compressor 6 pushes the high-temperature, high-pressure gaseous refrigerant into the condenser 7 through external water pipe 2, where it exchanges heat with the cooling medium (such as air or water), releasing heat and condensing into a high-pressure liquid state, thus liquefying it. The mixture of low-temperature, low-pressure liquid and gaseous refrigerant enters evaporator 8, absorbing heat from the dumplings and rice balls and evaporating, lowering their temperature and achieving a cooling effect. The refrigerant is then drawn back into compressor 6, and the cycle repeats, achieving both cooling and anti-oxidation freezing of the dumplings and rice balls. Simultaneously, PLC controller 1... 3. The fan 10 is activated to exchange air inside and outside the electrical compartment 3, providing fresh cooling medium for the condenser 7 and dissipating heat from the compressor 6. At the same time, the PLC controller 13 activates the temperature sensor 9. When the internal temperature of the freezer compartment 2 changes, the resistance of the thermistor of the temperature sensor 9 will change accordingly. By measuring the change in the resistance of the thermistor and converting it into an electrical signal (such as a voltage or current signal), the temperature information of a specified area inside the freezer compartment 2 can be obtained. The temperature sensor 9 sends the temperature information to the signal receiving terminal of the PLC controller 13 in real time. The PLC controller 13 adjusts the operating status of the compressor 6 based on the collected temperature information.
[0027] It is worth noting that the temperature sensor 9 disclosed in the above embodiments can be a B3950 thermistor sensor, and the PLC controller 13 controls the operation of the compressor 6, the temperature sensor 9 and the fan 10 using methods commonly used in the prior art.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
