[0065] In some embodiments of the present application, a refrigeration device is proposed. The refrigeration device may be a horizontal freezer or a vertical freezer or a refrigerator, etc., which are devices that can be used for refrigeration.

[0066] The refrigeration equipment structure includes:

[0067] The box body 100 has a storage chamber formed therein;

[0068] The storage chamber is a refrigerator or a freezer, and the storage chamber can be used to store food.

[0069] The door body 200 is connected to the box body 100 and is used to open and close the storage chamber.

[0070] In some embodiments, the door body 200 is rotatably connected to the box body 100 via a hinge to achieve the opening or closing function of the box body 100 .

[0071] A handle piece 300 is installed on the door body 200 , and the door body 200 can be opened and closed conveniently by assembling the handle piece 300 on the door body 200 .

[0072] The door lock assembly is connected to the box body 100 and the door body 200 and is used to lock or unlock the box body 100 and the door body 200.

[0073] The door body 200 and the cabinet 100 can be locked and fixed together by a door lock assembly connected to the cabinet 100 and the door body 200 to ensure the storage safety of the entire refrigeration equipment.

[0074] If the refrigeration equipment stores some medical vaccines or biological drugs, the door lock assembly can be used to ensure that the door body 200 is in a locked state, and there will be no accidental operation or mistaking by outsiders.

[0075] In some embodiments of the present application, the door lock assembly includes:

[0076] The lock hook component 400 is movably arranged in the handle component 300. The lock hook component 400 is configured to be movable relative to the handle component 300. Its position can be changed by moving relative to the handle component 300 so that it can adapt to the locking or unlocking action accordingly.

[0077] In some embodiments, the lock hook component 400 has a lock hook portion 410 , and the lock hook portion 410 is an insertion lock hole formed at one end of the lock hook component 400 .

[0078] In some embodiments of the present application, in order to achieve cooperation with the lock hook component 400, the refrigeration device is also correspondingly configured with a self-locking component, and the self-locking component is used to cooperate with the lock hook component 400 to achieve a locking effect.

[0079] The self-locking components include:

[0080] A self-locking base 510, mounted on the box 100;

[0081] In some embodiments of the present application, the self-locking base 510 includes a base body portion 511, and a connecting portion 512 that cooperates with the box 100 is formed on the base body portion 511;

[0082] The base body portion 511 is a base body plate, which is disposed in close contact with the box body 100 , and the connecting portion 512 is a locking hole formed on the base body portion 511 .

[0083] During setting, locking holes are provided at the upper and lower ends of the base body 511. During fixing, the base body 511 is fixed in the box body 100 by passing locking screws through the locking holes to achieve the connection and fixation between the self-locking base body 510 and the box body 100.

[0084] By setting locking holes at the upper and lower positions, when connected, the upper and lower ends are locked and fixed by locking screws, ensuring the firmness of the self-locking base 510 assembled on the box body 100 and preventing it from falling off.

[0085] The gravity self-locking member 520 is rotatably connected to the self-locking base 510 .

[0086] In some embodiments of the present application, the self-locking base 510 includes: a support portion 513 formed on the base body portion 511 , wherein the support portion 513 is disposed perpendicular to the base body portion 511 , and the support portion 513 is a support plate disposed perpendicular to the base body portion 511 .

[0087] There are two support parts 513 , which are arranged opposite to each other, and an installation space 514 is formed between the two support parts 513 . The gravity self-locking member 520 is arranged in the installation space 514 and is rotatably connected to the two support parts 513 on both sides.

[0088] The gravity self-locking member 520 is arranged in the installation space 514, and can be limited by the support parts 513 located on both sides thereof, so that when it rotates, it can be rotated in contact with the two support parts 513 without rotation deviation.

[0089] In some embodiments, the gravity self-locking member 520 has a locking position and an unlocking position;

[0090] When the gravity self-locking member 520 is in the locking position, it can be locked and fixed with the locking hook member 400;

[0091] When the gravity self-locking member 520 is in the unlocking position, it is separated from the locking hook member 400 and is in the unlocking state.

[0092] Among them, when in the unlocked position, the gravity self-locking component 520 can rotate from the unlocked position to the locked position under its own gravity, that is, the gravity self-locking component 520 can change its position by rotating relative to the self-locking base 510 through its own gravity, so that it automatically falls to the locked position.

[0093] When in the locking position, it can be inserted into the locking hook portion 410 moved below it to be locked and fixed with the locking hook component 400.

[0094] When the gravity self-locking member 520 rotates and falls to the locking position, it can be inserted and matched with the locking hook portion 410 to achieve locking.

[0095] When locking is required, force can be applied to the gravity self-locking member 520 first, so that the gravity self-locking member 520 rotates relative to the self-locking base 510 to the unlocked position, and then force is applied to the lock hook component 400, so that the lock hook component 400 movably arranged in the handle member 300 moves to the position below the gravity self-locking member 520, and then the gravity self-locking member 520 is released. The gravity self-locking member 520 rotates from the unlocked position to the locked position under the action of its own gravity, and is just stuck in the lock hook part 410 moved below it, so as to realize the locking and fixation between the gravity self-locking member 520 and the lock hook component 400, and also realize the locking and fixation between the door body 200 and the box body 100.

[0096] The refrigeration equipment is provided with a gravity self-locking member 520 and a lock hook member 400 that cooperate with each other. The gravity self-locking member 520 replaces the lock nose. When the door body 200 and the cabinet body 100 need to be locked, it is only necessary to turn the gravity self-locking member 520 to rotate it to the unlocking position, and then apply force to the lock hook member 400 to move it below the gravity self-locking member 520, and then release the gravity self-locking member 520. The locking process of the gravity self-locking member 520 and the lock hook member 400 does not require the use of a key to unlock, and the locking operation method is simple and convenient.

[0097] Furthermore, the door lock assembly structure on the refrigeration equipment can be locked entirely by components assembled on the door body 200 and the box body 100 without the need for keys, which can effectively avoid the problem of being unable to unlock the door body 200 due to key loss or forgetting.

[0098] In some embodiments of the present application, in order to facilitate the rotation of the gravity self-locking component 520, a toggle protrusion or a toggle handle is provided on the gravity self-locking component 520. When in use, the toggle protrusion or the toggle handle can be manually to flip it upward, thereby realizing the separation of the gravity self-locking component 520 and the locking hook component 400.

[0099] Alternatively, the gravity self-locking member 520 may be flipped upward to a certain angle by applying force to the push projection and then released, so that the gravity self-locking member 520 can fall down by gravity.

[0100] In some embodiments, in order to facilitate the user to directly move the gravity self-locking member 520 by hand, a plurality of protruding particles are provided on the side wall of the gravity self-locking member 520 .

[0101] During the setting, the toggling protrusions or protrusion particles can be simultaneously set on one side or both sides of the gravity self-locking member 520 .

[0102] In some embodiments of the present application, the refrigeration device includes:

[0103] The upper limit member 530 is arranged laterally between the two support parts 513 and is used to limit the upper rotation angle of the gravity deadweight member;

[0104] The upper limit component 530 is an upper limit rod laterally connected between the two support parts 513, which is used to limit the upward flipping angle of the gravity self-locking component 520 to prevent the gravity self-locking component 520 from flipping upward at too large an angle and flipping to the other side of the installation space 514.

[0105] The lower limit component 540 is formed on the self-locking base 510 and is used to limit the downward rotation angle of the gravity self-locking component 520 so that it remains in the locking position that cooperates with the locking hook component 400.

[0106] In some embodiments, the lower limiting component 540 is a lower limiting block, which is disposed perpendicular to the base body 511 and is used to limit the downward flipping angle of the gravity self-locking component 520 .

[0107] By cooperating with the upper limit component 530 and the lower limit component 540 , the rotation angle of the gravity self-locking component 520 can be maintained within the range of 0-40 degrees to prevent the gravity self-locking component 520 from turning over at too large an angle and being difficult to operate.

[0108] At the same time, when the gravity self-locking component 520 flips to the position of the lower limit component 540, its end will abut against the lower limit component 540. The limiting of the lower limit component 540 can keep the gravity self-locking component 520 in the locking position and will not continue to flip downward, so that it can just cooperate with the locking hook part 410 to ensure that the two can be accurately matched for locking.

[0109] In some embodiments of the present application, the gravity self-locking member 520 has a rotation hinge point, and the outer diameter of the gravity self-locking member 520 gradually increases from a direction close to the rotation hinge point to a direction away from the rotation hinge point.

[0110] The gravity self-locking component 520 is configured to have a smaller outer diameter near the rotating hinge point and a larger outer diameter away from the rotating hinge point, so that the weight of the entire gravity self-locking component 520 is greater as it is closer to the bottom position and the gravity is smaller as it is closer to the upper position. This ensures that when the gravity self-locking component 520 is swung to the upper position, it can automatically rotate to the locking position under the action of its own gravity, so as to always achieve the purpose of self-locking through its own weight.

[0111] In some embodiments of the present application, the refrigeration device includes:

[0112] The rotation shaft 550 is used to connect the self-locking weight member and the support part 513, and the distance from the rotation shaft 550 to the lower limit member 540 is smaller than the distance from the rotation hinge point to the outer edge of the self-locking weight member.

[0113] The rotating shaft 550 is used to realize the rotation of the self-locking weight member relative to the supporting part 513. When set, the rotating shaft 550 is inserted into the two supporting parts 513 and the self-locking weight member to connect the three together.

[0114] In some embodiments of the present application, the refrigeration device includes:

[0115] A lock hook housing 560, wherein the lock hook housing 560 is fixed inside the handle member 300;

[0116] In some embodiments of the present application, a mounting groove is provided in the handle member 300 , and the lock hook housing 560 is inserted into the mounting groove to achieve fixation with the handle member 300 .

[0117] A plurality of limiting protrusions are arranged on the inner wall of the installation groove, and the plurality of limiting protrusions are evenly arranged along the circumference of the inner wall of the installation groove, and insertion spaces are formed between the plurality of limiting protrusions.

[0118] In some embodiments, the locking hook housing 560 is a circular housing, and the mounting groove is also correspondingly circular. During assembly, the circular housing is interference-fitted into the insertion space formed by a plurality of limiting protrusions and is fixed in position.

[0119] The lock hook component 400 includes: a pressing portion 420, arranged at an end of the lock hook component 400 opposite to the lock hook portion 410;

[0120] By applying force to the pressing portion 420 , the entire lock hook component 400 can be driven to move relative to the lock hook housing 560 to change the position of the lock hook portion 410 at the other end.

[0121] A movable guide portion 430, connecting the pressing portion 420 and the locking hook portion 410, wherein the movable guide portion 430 is disposed in the locking hook housing 560;

[0122] The movable guide portion 430 is a movable guide column, one end of which is connected to the pressing portion 420 , and the other end of which is connected to the locking hook portion 410 .

[0123] When the lock hook component 400 moves relative to the lock hook housing 560 , it moves along the lock hook housing 560 via the moving guide portion 430 .

[0124] In some embodiments of the present application, the pressing portion 420 is a pressing sheet, and the vertical moving guide portion 430 thereof is extended downward from the moving guide portion 430 .

[0125] The pressing piece may be in the shape of a sector, a circle, a rectangle, etc., as long as it is convenient for the user to place a finger on it and perform a pressing operation.

[0126] The elastic element 440 is sleeved on the moving guide portion 430 , with one end abutting against the pressing portion 420 and the other end abutting against the lock hook housing 560 , so as to reset the lock hook component 400 .

[0127] When the lock hook component 400 moves, the pressing portion 420 and the moving guide portion 430 both move along the lock hook shell 560. Since one end of the elastic element 440 rests on the pressing portion 420, and the other end rests on the lock hook shell 560, when the pressing portion 420 moves, the elastic element 440 between the pressing portion 420 and the lock hook shell 560 will be compressed, and at the same time, the lock hook portion 410 at the end will extend to the position of the gravity self-locking component 520, and be locked with the gravity self-locking component 520.

[0128] When unlocking is required, the gravity self-locking component 520 can be moved to rotate upward and separate from the lock hook part 410. At this time, the limitation of the gravity self-locking component 520 on the lock hook component 400 is eliminated, and the lock hook component 400 will pop out in the direction away from the gravity self-locking component 520 under the reverse force of the elastic element 440 to separate from the gravity self-locking component 520, and the automatic resetting of the lock hook component 400 is achieved through the elastic element 440.

[0129] In some embodiments, the elastic element 440 is a spring or a spring sheet that is bent and deformed when subjected to force, and recovers when the force is removed.

[0130] In some embodiments of the present application, a receiving portion 561 is formed inside the lock hook housing 560 and passes through the lock hook portion 410. The outer diameter of the lock hook portion 410 is larger than the receiving portion 561.
