[0010] Preferably, the cabinet and the rotating structure are connected to form a rotating structure through a base and the docking rod, and the diagonal length of the cabinet is the same as the diameter of the rotating structure.

[0011] Preferably, the rotating structure also includes a blocking bracket, a docking bracket, a transmission gear, a rotating gear, an output gear, a reducer and a driving motor, and a docking bracket is arranged at the center of the blocking bracket and the outer shell, and a transmission gear is arranged below the blocking bracket, and a rotating gear is arranged on the side of the transmission gear, and an output gear is arranged above the rotating gear, and a reducer is arranged at the center of the transmission gear and the output gear, and a driving motor is arranged on the side of the reducer away from the transmission gear, and the transmission gear, rotating gear, output gear and reducer are meshed with each other.

[0013] Preferably, the outward extension protection assembly also includes a rotating bracket, a first gear, a mounting bracket, a second gear, a toothed plate and an adjusting gear, and the first gear is arranged above the rotating bracket, and the mounting bracket is arranged on the side of the first gear away from the rotating bracket, and the second gear is arranged at the center of the two groups of the first gears, and the toothed plate is arranged at the center of the two groups of the second gears, and an adjusting gear is arranged above the second gear, a fixing structure is formed between the blocking block and the rotating bracket by bolts, and a rotating structure is formed between the rotating bracket and the mounting bracket by the first gear, and a meshing structure is formed between the first gear, the second gear, the toothed plate and the adjusting gear.

[0014] Preferably, the outward extension protection assembly also includes a locking bracket, a limit bracket, a limit head, a vibration sensor probe, a push rod and a limit block, and a limit bracket is arranged on the side of the locking bracket, and a limit head is arranged on the side of the limit bracket away from the locking bracket, and a vibration sensor probe is arranged below the locking bracket, and a push rod is arranged below the limit bracket, and a limit block is arranged at the center of the two groups of limit blocks.

[0015] Preferably, a method for using a variable frequency compression temperature control high-sealing refrigerator comprises the following steps:

[0016] Step 1: First, the compressor in the cabinet runs, and the compressor sucks the low-temperature and low-pressure refrigerant gas in the evaporation bracket, compresses it into high-temperature and high-pressure gas, and then transports it to the first condensation bracket and the second condensation bracket. In the first condensation bracket and the second condensation bracket, it then evaporates again and is sucked into the compressor again, forming a closed circulation system;

[0017] Step 2: When the cabinet is in use, items are placed in the refrigerator and freezer, and the first door and the second door are closed. When the first door or the second door is opened, the items are taken out, and the first door and the second door are closed, the vibration sensor probe detects the vibration generated by the cabinet, and after confirming that the vibration threshold does not exceed the specified range, the cabinet is operating normally;

[0018] Step 3: When the cabinet is subjected to a severe impact during use, the vibration sensor probe detects the vibration of the cabinet. When the vibration exceeds the specified threshold, the rotating structure operates, and the driving motor in the rotating structure drives the reducer to operate, and the reducer drives the transmission gear, and the transmission gear drives the rotating gear. In the sequential transmission process, the rotating gear drives the output gear to rotate, so that the docking rod connected to the output gear drives the connected connecting base to rotate, and the cabinet on the connecting base rotates counterclockwise;

[0019] Step 4: At this time, when the cabinet body rotates counterclockwise, due to the connection method adopted by the first door and the second door bracket, when the cabinet body rotates counterclockwise, the first door and the second door that are still in the open and closed state can be retracted during the rotation of the cabinet body, so that the rotation of the cabinet body is not affected by the door, and then the cabinet body is rotated 180 degrees, and the extension protection component is moved to the outermost side;

[0020] Step 5: After the cabinet moves to the end, the outward extension protection assembly makes the push rod move simultaneously in the shell of the rotating structure. Due to the inclined groove provided on the outer surface of the shell, when the cabinet moves 180°, the push rod enters the shell. Then, the restriction of the limit bracket by the push rod disappears, so that the safety plate slides along the protection bracket, and the safety plate slides downward, so that the safety plate slides into the placement groove. After the safety plate slides down, the safety plate contacts the damping bracket in the placement bracket, so that the safety plate completely covers the placement groove, so that the combination of the protection bracket and the safety plate forms a whole.

[0021] Step 6: When the safety plate falls into the placement groove, the blocking block is free from the restriction of the safety plate, so that the blocking block moves along the docking groove, so that the blocking block is merged into the interior of the connecting groove, so that when the safety plate is reset upward, the path for the safety plate to move upward is restricted by the blocking block, so as to prevent the safety plate from moving upward;

[0022] Step seven: Then when the cabinet is safe, two people work together, one touches the switch to reset the blocking block to the inside of the docking groove, and the other pushes the safety plate upwards so that the safety plate slides back through the connecting groove. Then when the safety plate is reset, the restricted switch is cancelled, and the safety plate is restricted by the limit block. After the limit block completes the blocking of the safety plate, the cabinet is reset by rotating the structure, so that the push rod continuously contracts along the groove of the outer shell, so that the push rod pushes the limit bracket, so that the limit head in the limit bracket is reinserted into the interior of the safety plate to complete the fixation of the safety plate. At this time, the limit head completes the fixation of the safety plate, and the restriction of the safety plate on the blocking block disappears.

[0023] Technical effects and advantages of this application:

[0024] 1. Compared with the prior art, this variable frequency compression temperature control high-sealing refrigerator and its use method, when the variable frequency compression temperature control module is in operation, its evaporation bracket is fitted with the heat dissipation partition plate, and the low-temperature and low-pressure refrigerant gas in the evaporation bracket is continuously cooled down by the evaporation bracket during the transportation process, so that the temperature transferred from the control room to the heat dissipation partition plate will be continuously stripped off, so that when the variable frequency compression temperature control module is in continuous operation, its electronic equipment will not be affected by high temperature.

[0025] 2. Compared with the prior art, this variable frequency compression temperature controlled high-sealing refrigerator and its use method use a rotating structure, wherein when the refrigerator is placed, the back of the refrigerator is often brought close to the wall. Therefore, when the cabinet is placed again, the cabinet on the rotating structure of the movable bracket is moved, so that when the rotating structure confirms the space where it is located, the space where it is located can facilitate the rotation of the cabinet, thereby completing the placement of the cabinet. When the cabinet is damaged, the vibration sensor probe detects the vibration of the cabinet. When the threshold is exceeded, the rotating structure drives the cabinet to rotate, so that the exit positions of the refrigerator and freezer of the cabinet are close to the wall, thereby directly limiting the external space of the refrigerator and freezer to reduce the space for taking items, and directly retaining the extended protection component in the external environment.

[0026] 3. Compared with the prior art, the variable frequency compression temperature-controlled high-sealing refrigerator and its use method, the push rod in the outward extension protection component is restricted by the outer shell in the rotating structure, so that the limit bracket in the engaging bracket is restricted, and the limit head in the limit bracket is continuously contracted into the limit bracket, so that the restriction of the safety plate disappears, so that the safety plate slides along the connecting groove into the interior of the placement groove, and the restriction of the blocking block disappears, so that the blocking block is re-integrated into the interior of the connecting groove, so that the safety plate cannot be reset, so that the outward extension protection component protects the interior of the cabinet, thereby reducing the damage to the cabinet.

[0027] 4. Compared with the prior art, this variable frequency compression temperature control high-sealing refrigerator and its use method, when the variable frequency compression temperature control module is in operation, its evaporation bracket is fitted with the heat dissipation partition plate, and the low-temperature and low-pressure refrigerant gas in the evaporation bracket is continuously cooled down by the evaporation bracket during the transportation process, so that the temperature transferred from the control room to the heat dissipation partition plate will be continuously stripped off, so that when the variable frequency compression temperature control module is in continuous operation, its electronic equipment will not be affected by high temperature.

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example 1

[0038] As attached Figures 1 to 8A variable frequency compression temperature control high sealing refrigeration cabinet shown in the figure comprises a cabinet body 1, a rotating structure 3 and an outward extension protection component 5, the outward extension protection component 5 is arranged on the side of the cabinet body 1, and a connecting base 2 is installed below the cabinet body 1 by bolts, and a rotating structure 3 is arranged on a layer of the connecting base 2 away from the cabinet body 1, and a movable bracket 4 is arranged on a side of the rotating structure 3 away from the connecting base 2, and a connecting bracket 6 is arranged below the outward extension protection component 5, and the rotating structure 3 includes an outer shell 17, a connecting plate 18, a sealing collar 19 and a docking rod 20, and the outer shell 17 Connecting plates 18 are connected on both sides of the inner wall, and a sealing ring 19 is arranged above the connecting plate 18, and a docking rod 20 is arranged on the side of the sealing ring 19 away from the connecting plate 18, and the outward extension protection component 5 includes a protection bracket 27, a safety plate 28, a placement groove 29, a connecting groove 31 and a switch 32, and a safety plate 28 is arranged on both sides of the inner wall of the protection bracket 27, and a placement groove 29 is arranged below the safety plate 28, and a connecting groove 31 is arranged at the center of the protection bracket 27 and the safety plate 28, and a switch 32 is arranged at the center of the two groups of connecting grooves 31.

[0039] Among them: when the refrigerator is placed in a dangerous environment, such as an earthquake and cargo collision, the refrigerator is often placed against the wall due to its structure. Therefore, when a problem occurs, the cabinet body 1 is rotated by the rotating structure 3 under the refrigerator, so that the cabinet body 1 rotates counterclockwise. Therefore, when the refrigerator rotates counterclockwise, even if the refrigerator door is opened, the rotation of the cabinet body 1 will not be restricted by the door. Then, when the cabinet body 1 rotates, the push rod 46 slides along the groove of the rotating structure 3, so that the push rod 46 moves downward, so that the restriction of the push rod 46 on the engaging bracket 42 is cancelled, and the limit block 47 connected to the push rod 46 is simultaneously retracted into the interior of the protective bracket 27, so that the protective bracket 27 restricts the safety plate 28. The control is cancelled, so that the safety plate 28 moves upward, so that the safety plate 28 covers the inside of the placement slot 29, thereby completing the safety protection of the inside of the cabinet 1, and then after the danger disappears, two people operate at the same time, so that one person controls the switch 32 to reset the blocking block 34, and the other person pushes the safety plate 28 to reset, so that the safety plate 28 and the limiting bracket 43 are engaged, thereby completing the support of the safety plate 28, and then when the cabinet 1 is reset, the pushing rod 46 is reset along the outer shell 17 at this time, so that the limiting block 47 is retracted into the inside of the protective bracket 27, and when the limiting bracket 43 in the engaging bracket 42 is restricted by the pushing rod 46, the limiting head 44 in the limiting bracket 43 is reinserted into the inside of the safety plate 28, thereby completing the restriction of the safety plate 28. Example 2

[0040] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working method. Figures 1 to 8 As shown, see the following description for details:

[0041] As a preferred embodiment, the cabinet 1 includes a first door 101, a second door 102, an outer box board 103, a freezer compartment 14, a refrigerator compartment 15 and a placement bracket 16, and the second door 102 is arranged below the first door 101, and the outer box board 103 is arranged on both sides of the first door 101, and the freezer compartment 14 is arranged at the center of the cabinet 1 and the first door 101, and the refrigerator compartment 15 is arranged at the center of the cabinet 1 and the second door 102, and the placement bracket 16 is installed on both sides of the inner wall of the refrigerator compartment 15, and then the first door 101 is arranged. When the cabinet body 1 is in use, due to the limitation of the hinge of the cabinet body 1, even if the first door 101 or the second door 102 is opened, the opening space of the first door 101 and the second door 102 will not be greater than 180°, thereby preventing the first door 101 and the second door 102 from affecting the rotation of the cabinet body 1. At the same time, the outer box plate 103 is thickened on both sides of the cabinet body 1, so that when the two sides of the cabinet body 1 are hit, the outer box plate 103 can still protect the first condensation bracket 8 and the second condensation bracket 9 inside the cabinet body 1.

[0042] As a preferred embodiment, the cabinet 1 also includes a motor room 7, a first condensing bracket 8, a second condensing bracket 9, a variable frequency compression temperature control module 10, a compressor 11, a second partition plate 12 and an evaporation bracket 13, and the compressor 11 is placed above the inner wall of the motor room 7, and the second partition plate 12 is arranged on the side of the compressor 11, and the evaporation bracket 13 is arranged on the side of the second partition plate 12 away from the compressor 11, and the variable frequency compression temperature control module 10 is arranged above the motor room 7, and the cabinet 1 and the outer box plate 103 are arranged at the center. There is a first condensing bracket 8, and a second condensing bracket 9 is arranged below the first condensing bracket 8. The core of the cabinet 1 includes a compressor 11, a first condensing bracket 8 and an evaporating bracket 13, etc. The variable frequency compression temperature control module 10 includes a control chamber 48, a convection duct 49 and a heat dissipation partition plate 50, and the side of the control chamber 48 is provided with a convection duct 49, and the control chamber 48 and the convection duct 49 are provided below the heat dissipation partition plate 50, wherein the electronic component structure of the variable frequency compression temperature control module 10 and the corresponding The system pipelines are separated by setting the pipelines at a position closer to the compressor 11, so that the connection positions of the pipelines are concentrated in one place, and the variable frequency compression temperature control module 10 separates the convection pipeline 49 and the control chamber 48 through the heat dissipation partition plate 50, so as to reduce the influence of the heat transferred to the outside by the compressor 11 during the operation of the compressor 11. At this time, when the variable frequency compression temperature control module 10 is in operation, its evaporation bracket 13 is fitted with the heat dissipation partition plate 50, and the low-temperature and low-pressure refrigerant gas in the evaporation bracket 13 is continuously cooled by the heat dissipation partition plate 50 during the transportation process, so that during the operation of the refrigerator, the heat generated by the operation of the control chamber 48 in the variable frequency compression temperature control module 10 will be continuously stripped off, so that when the variable frequency compression temperature control module 10 is in continuous operation, its electronic equipment will not be affected by high temperature, and when the detected temperature changes, the control chamber 48 dynamically adjusts the operating frequency of the compressor 11 according to the feedback of the temperature sensor. When the refrigerator needs more cooling or heating, the control room 48 will increase the operating frequency of the compressor 11; conversely, when the system temperature is close to the set point, the control room 48 will reduce the operating frequency of the compressor 11 to maintain a stable temperature and save energy. When the compressor 11 is running, the compressor 11 sucks the low-temperature and low-pressure refrigerant gas in the evaporation bracket 13, compresses it into a high-temperature and high-pressure gas, and then transports it to the first condensation bracket 8. In the first condensation bracket 8, the high-temperature and high-pressure refrigerant gas releases heat and condenses into a liquid state, and then enters the evaporation bracket 13 through an expansion valve or a capillary tube to reduce pressure. In the evaporation bracket 13, the refrigerant absorbs the heat inside the cabinet 1, evaporates into a low-temperature and low-pressure gas, and is sucked in by the compressor 11 again, forming a closed circulation system.

[0043] As a preferred embodiment, the cabinet 1 and the rotating structure 3 are connected by the base 2 and the docking rod 20 to form a rotating structure 3, and the diagonal length of the cabinet 1 is the same as the diameter of the rotating structure 3. When the cabinet 1 is rotating, the diagonal length of the cabinet 1 is the same as the length of the rotating structure 3. Therefore, when the cabinet 1 is placed, the cabinet 1 checks whether the space can accommodate the cabinet 1 through the rotating structure 3, thereby facilitating the placement of the cabinet 1.

[0044] As a preferred embodiment, the rotating structure 3 also includes a blocking bracket 21, a docking bracket 2101, a transmission gear 22, a rotating gear 23, an output gear 24, a reducer 25 and a driving motor 26, and a docking bracket 2101 is arranged at the center of the blocking bracket 21 and the outer shell 17, and a transmission gear 22 is arranged below the blocking bracket 21, and a rotating gear 23 is arranged on the side of the transmission gear 22, and an output gear 24 is arranged above the rotating gear 23, and a reducer 25 is arranged at the center of the transmission gear 22 and the output gear 24, and a driving motor 26 is arranged on the side of the reducer 25 away from the transmission gear 22, and the transmission gear 22, the rotating gear 23, the output gear 24 and the reducer 25 are meshed with each other. When the rotating structure 3 is in use, the reducer 25 and the drive motor 26 are placed in the internal gap between the transmission gear 22 and the output gear 24, and the reducer 25 and the drive motor 26 are simultaneously in the shell 17 with the rotating gear 23, so as to maintain the structure of the rotating structure 3 as a cylindrical structure, so that the rotating structure 3 can be more convenient to assemble the cabinet 1 and the movable bracket 4, and a larger torque is applied to the output gear 24 through the transmission gear 22 and the rotating gear 23, so that the rotating structure 3 can rotate the cabinet 1 structure with a small output force, and then the blocking bracket 21 in the rotating structure 3 cooperates with the docking bracket 2101 to connect to the shell 17, so that the blocking bracket 21 restricts the shell 17 while also restricting the rotating gear 23 to prevent the rotating gear 23 from disengaging.

[0045] As a preferred embodiment, the outward extension protection component 5 also includes a heat dissipation groove 30, a docking groove 33, a blocking block 34 and a damping bracket 35, and a docking groove 33 is arranged above the heat dissipation groove 30, and a blocking block 34 is arranged above the inner wall of the docking groove 33, and a damping bracket 35 is installed above the inner wall of the connecting bracket 6, and then the heat dissipation groove 30 is arranged in the outward extension protection component 5, which is used for dissipating the heat of the cabinet 1 through the heat dissipation groove 30 during operation when the outward extension protection component 5 is not in use.

[0046] As a preferred embodiment, the outward extension protection component 5 also includes a rotating bracket 36, a first gear 37, a mounting bracket 38, a second gear 39, a toothed plate 40 and an adjusting gear 41, and the first gear 37 is arranged above the rotating bracket 36, and the mounting bracket 38 is arranged on the side of the first gear 37 away from the rotating bracket 36, and the second gear 39 is arranged at the center of the two groups of first gears 37, and the toothed plate 40 is arranged at the center of the two groups of second gears 39, and the adjusting gear 41 is arranged above the second gear 39, a fixing structure is formed between the blocking block 34 and the rotating bracket 36 by bolts, and a rotating structure 3 is formed between the rotating bracket 36 and the mounting bracket 38 by the first gear 37, and a meshing structure is formed between the first gear 37, the second gear 39, the toothed plate 40 and the adjusting gear 41, and then when the safety plate 28 needs to be used, the safety plate 28 is installed at this time. When the whole plate 28 slides along the connecting groove 31, the safety plate 28 falls into the placement groove 29 again, so that the restriction of the blocking block 34 in the docking groove 33 disappears, and the blocking block 34 is merged into the docking groove 33, so that even when the safety plate 28 is pushed to reset, the safety plate 28 is restricted by the blocking block 34 to prevent the safety plate 28 from resetting, thereby protecting the motor room 7 structure in the cabinet 1, and when the blocking block 34 needs to be reset, the switch 32 is turned on at this time, so that the adjusting gear 41 in the switch 32 drives the tooth plate 40 to move, so that the second gear 39 carried by the tooth plate 40 rotates, and the first gear 37 carried by the second gear 39 rotates, so that the blocking block 34 connected to the rotating bracket 36 is driven by the first gear 37 to reset to the inside of the docking groove 33, thereby eliminating the restriction on the reset of the safety plate 28.

[0047] As a preferred embodiment, the outward extension protection component 5 also includes a snap-fit ​​bracket 42, a limit bracket 43, a limit head 44, a vibration sensor probe 45, a push rod 46 and a limit block 47, and the side of the snap-fit ​​bracket 42 is provided with a limit bracket 43, and the side of the limit bracket 43 away from the snap-fit ​​bracket 42 is provided with a limit head 44, and the bottom of the snap-fit ​​bracket 42 is provided with a vibration sensor probe 45, and the bottom of the limit bracket 43 is provided with a push rod 46, and the center of the two groups of limit blocks 47 is provided with a limit block 47, and then the protection bracket 27 is connected to the push rod 46 through a spring, so that when there is space at the bottom of the push rod 46, the push rod 46 is still restricted. The limit of the spring causes the push rod 46 to continue to move downward. Then, when the outward extension protection component 5 is used, the limit of the push rod 46 can be released by the rotating structure 3, so that the push rod 46 continues to move downward, so that the limit of the push rod 46 on the engaging bracket 42 is cancelled, and the limit head 44 in the limit bracket 43 is contracted, so that the limit of the engaging bracket 42 on the safety plate 28 disappears, so that the safety plate 28 moves downward, and the limit block 47 moves simultaneously with the movement of the push rod 46. Because the limit block 47 is provided with a spring inside, when the limit block 47 moves, the limit block 47 is limited by the push rod 46. Therefore, when the cabinet 1 rotates, the limit block 47 is exposed, but the limit block 47 prevents the safety plate 28 from being exposed. Then, when the safety plate 28 moves downward, the limit block 47 is exposed. Then, when the safety plate 28 is reset, the safety plate 28 moves upward. Since the bottom of the limit block 47 is an inclined surface and a spring is arranged inside, when the safety plate 28 is reset, the safety plate 28 is supported by the limit block 47. Then, when the cabinet 1 is reset, the push rod 46 drives the locking bracket 42 to lock the safety plate 28, and the limit block 47 brought by the push rod 46 is retracted into the inside of the protective bracket 27 to stop the limit block 47 from restricting the safety plate 28.

[0048] As a preferred embodiment, a method for using a variable frequency compression temperature control high-sealing refrigerator comprises the following steps:

[0049] Step 1: First, the compressor 11 in the cabinet 1 is running, and the compressor 11 sucks the low-temperature and low-pressure refrigerant gas in the evaporation bracket 13, compresses it into high-temperature and high-pressure gas, and then transports it to the first condensation bracket 8 and the second condensation bracket 9. In the first condensation bracket 8 and the second condensation bracket 9, it is then re-evaporated and sucked into the compressor 11 again, forming a closed circulation system;

[0050] Step 2: When the cabinet 1 is used, the items are placed in the refrigerator compartment 15 and the freezer compartment 14, and the first door 101 and the second door 102 are closed. When the first door 101 or the second door 102 is opened, the items are taken out, and the first door 101 and the second door 102 are closed. At this time, the vibration sensor probe 45 detects the vibration generated by the cabinet 1. When it is confirmed that the vibration threshold does not exceed the specified range, the cabinet 1 is operating normally.

[0051] Step 3: When the cabinet 1 is subjected to a severe impact during use, the vibration sensor probe 45 detects the vibration of the cabinet 1. When the vibration exceeds the specified threshold, the rotating structure 3 operates, and the driving motor 26 in the rotating structure 3 drives the reducer 25 to operate, and the reducer 25 drives the transmission gear 22, and the transmission gear 22 drives the rotating gear 23. In the sequential transmission process, the rotating gear 23 drives the output gear 24 to rotate, so that the docking rod 20 connected to the output gear 24 drives the connected connecting base 2 to rotate, and the cabinet 1 on the connecting base 2 rotates counterclockwise;

[0052] Step 4: At this time, when the cabinet 1 rotates counterclockwise, due to the connection method adopted by the brackets of the first door 101 and the second door 102, when the cabinet 1 rotates counterclockwise, the first door 101 and the second door 102, which are still in the open and closed state, can be retracted during the rotation of the cabinet 1, so that the rotation of the cabinet 1 is not affected by the door, and then the cabinet 1 is rotated 180°, and the extension protection component 5 is moved to the outermost side;

[0053] Step 5: After the cabinet 1 moves to the end, the outward extension protection component 5 makes the push rod 46 move simultaneously in the shell 17 of the rotating structure 3. Due to the inclined groove provided in the outer surface of the shell 17, when the cabinet 1 moves 180°, the push rod 46 enters the shell 17, and then the restriction of the limit bracket 43 by the push rod 46 disappears, so that the safety plate 28 slides along the protection bracket 27, and the safety plate 28 slides downward, so that the safety plate 28 slides into the inside of the placement groove 29, and then after the safety plate 28 slides down, the safety plate 28 contacts the damping bracket 35 in the placement bracket 16, so that the safety plate 28 completely covers the placement groove 29, so that the combination of the protection bracket 27 and the safety plate 28 forms a whole;

[0054] Step 6: When the safety plate 28 falls into the placement groove 29, the blocking block 34 is free from the restriction of the safety plate 28, so that the blocking block 34 moves along the docking groove 33, so that the blocking block 34 is merged into the interior of the connecting groove 31, so that when the safety plate 28 is reset upward, the path for the safety plate 28 to move upward is restricted by the blocking block 34, so as to prevent the safety plate 28 from moving upward;

[0055] Step seven: Then when the cabinet 1 is safe, two people work together, one touches the switch 32 to reset the blocking block 34 to the inside of the docking groove 33, and the other pushes the safety plate 28 upward so that the safety plate 28 slides and resets through the connecting groove 31. Then, when the safety plate 28 is reset, the restricted switch 32 is cancelled, and the safety plate 28 is restricted by the limit block 47. After the limit block 47 completes the blocking of the safety plate 28, the cabinet 1 is reset by the rotating structure 3, so that the push rod 46 continuously contracts along the groove of the outer shell 17, so that the push rod 46 pushes the limit bracket 43, so that the limit head 44 in the limit bracket 43 is reinserted into the interior of the safety plate 28 to complete the fixation of the safety plate 28. At this time, the limit head 44 completes the fixation of the safety plate 28, and the restriction of the safety plate 28 on the blocking block 34 disappears.

[0056] The working process of the present application is as follows: first, the compressor 11 in the cabinet 1 is operated, and the compressor 11 sucks the low-temperature and low-pressure refrigerant gas in the evaporation bracket 13, compresses it into high-temperature and high-pressure gas, and then transports it to the first condensation bracket 8 and the second condensation bracket 9. In the first condensation bracket 8 and the second condensation bracket 9, it is then re-evaporated and sucked into the compressor 11 again, forming a closed circulation system;

[0057] Then, when the cabinet 1 is used again, when the items are placed in the refrigerator compartment 15 and the freezer compartment 14, the first door 101 and the second door 102 are closed. When the first door 101 or the second door 102 is opened, the items are taken out, and the first door 101 and the second door 102 are closed, the vibration sensor probe 45 detects the vibration generated by the cabinet 1. When it is confirmed that the vibration threshold does not exceed the specified range, the cabinet 1 is operating normally.

[0058] Then, when the cabinet 1 is subjected to a severe impact during use, the vibration sensor probe 45 detects the vibration of the cabinet 1. When the vibration exceeds the specified threshold, the rotating structure 3 operates, and the driving motor 26 in the rotating structure 3 drives the reducer 25 to operate, and the reducer 25 drives the transmission gear 22, and the transmission gear 22 drives the rotating gear 23. In the sequential transmission process, the rotating gear 23 drives the output gear 24 to rotate, so that the docking rod 20 connected to the output gear 24 drives the connected connecting base 2 to rotate, and the cabinet 1 on the connecting base 2 rotates counterclockwise;

[0059] At this time, when the cabinet 1 rotates counterclockwise, due to the connection method adopted by the brackets of the first door 101 and the second door 102, when the cabinet 1 rotates counterclockwise, the first door 101 and the second door 102, which are still in the open and closed state, can be retracted during the rotation of the cabinet 1, so that the rotation of the cabinet 1 is not affected by the door, and then the cabinet 1 is rotated 180°, and the extension protection component 5 is moved to the outermost side;

[0060] Then, after the cabinet 1 moves to the end, the outward extension protection component 5 makes the push rod 46 move simultaneously in the shell 17 of the rotating structure 3. Due to the inclined groove provided in the outer surface of the shell 17, when the cabinet 1 moves 180°, the push rod 46 enters the shell 17. Then, the restriction of the limit bracket 43 by the push rod 46 disappears, so that the safety plate 28 slides along the protection bracket 27, and the safety plate 28 slides downward, so that the safety plate 28 slides into the placement groove 29. Then, after the safety plate 28 slides down, the safety plate 28 contacts the damping bracket 35 in the placement bracket 16, so that the safety plate 28 completely covers the placement groove 29, so that the combination of the protection bracket 27 and the safety plate 28 forms a whole.

[0061] Then, when the safety plate 28 falls into the placement groove 29, the blocking block 34 is free from the restriction of the safety plate 28, so that the blocking block 34 moves along the docking groove 33, so that the blocking block 34 is merged into the interior of the connecting groove 31, so that when the safety plate 28 is reset upward, the path for the safety plate 28 to move upward is restricted by the blocking block 34, so as to prevent the safety plate 28 from moving upward;

[0062] Then when the cabinet 1 is safe, two people work together, one touches the switch 32 to reset the blocking block 34 to the inside of the docking groove 33, and the other pushes the safety plate 28 upward, so that the safety plate 28 slides and resets through the connecting groove 31. Then, when the safety plate 28 is reset, the restricted switch 32 is cancelled, and the safety plate 28 is restricted by the limit block 47. After the limit block 47 completes the blocking of the safety plate 28, the cabinet 1 is reset by the rotating structure 3, so that the push rod 46 continuously contracts along the groove of the shell 17, so that the push rod 46 pushes the limit bracket 43, so that the limit head 44 in the limit bracket 43 is reinserted into the interior of the safety plate 28 to complete the fixation of the safety plate 28. At this time, the limit head 44 completes the fixation of the safety plate 28, and the restriction of the safety plate 28 on the blocking block 34 disappears. The above is the working principle of this variable frequency compression temperature control high sealing cold storage cabinet and its use method.

When the first door (101) or the second door (102) is opened, the items are taken out, and the first door (101) and the second door (102) are closed. At this time, the vibration sensor probe (45) detects the vibration generated by the cabinet (1). When it is confirmed that the vibration threshold does not exceed the specified range, the cabinet (1) is operating normally. Step 3: When the cabinet (1) is subjected to a severe impact during use, the vibration sensor probe (45) detects the vibration of the cabinet (1). When the vibration exceeds a specified threshold, the rotating structure (3) operates, and the driving motor (26) in the rotating structure (3) drives the reducer (25) to operate, and the reducer (25) drives the transmission gear (22), and the transmission gear (22) drives the rotating gear (23). In the sequential transmission process, the rotating gear (23) drives the output gear (24) to rotate, so that the docking rod (20) connected to the output gear (24) drives the connected connecting base (2) to rotate, and the cabinet (1) on the connecting base (2) rotates counterclockwise; Step 4: At this time, when the cabinet (1) rotates counterclockwise, due to the connection method adopted by the brackets of the first door (101) and the second door (102), when the cabinet (1) rotates counterclockwise, the first door (101) and the second door (102) which are still in the open and closed state can be retracted during the rotation of the cabinet (1), so that the rotation of the cabinet (1) is not affected by the doors, and then the cabinet (1) is rotated 180 degrees, and the extension protection component (5) is moved to the outermost side; Step 5: After the cabinet (1) moves to the end, the outward extension protection component (5) causes the push rod (46) to move simultaneously in the housing (17) of the rotating structure (3).
