Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a refrigeration equipment structure which can be automatically closed by the weight of a door body. Background Art

[0002] Existing refrigeration equipment, such as refrigerators, freezers, wine cabinets, display cabinets, etc., can be used to take out items stored in the storage chamber of the refrigeration equipment by rotating and opening the door body. The door opening angle of the above refrigeration equipment is usually between 10 and 115 degrees.

[0003] The existing refrigeration equipment door body is a conventional hinged door body structure, which has no rebound effect. After the user opens the door body to take out the items, the user needs to manually operate the door body to close the door body, which has a poor user experience;

[0004] With continuous development, in order to enhance the sealing effect of the door or enhance the convenience of closing the door, some refrigeration equipment adopts a suction-assistant structure. This structure needs to be closed to a very small angle when closing the door, generally less than 5° to automatically close. The usage mode is single and cannot meet the user's needs for taking items at different opening angles, resulting in poor user experience.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0083] The utility model provides an embodiment of a refrigeration device, comprising:

[0084] The box body 100 has a refrigerator compartment 110 and a freezer compartment arranged vertically therein;

[0085] The box body 100 includes a box shell and an inner container component arranged inside the box shell.

[0086] In some embodiments of the present application, the liner component includes a blister liner for the refrigerating chamber 110 and a blister liner for the freezing chamber.

[0087] A refrigerating chamber 110 is defined in the blister liner of the refrigerating chamber 110 , and the refrigerating chamber 110 is arranged above the freezing chamber to realize refrigeration and preservation of food;

[0088] A shelf component is provided in the refrigerating chamber 110 for carrying and supporting food, and storage compartments are correspondingly provided on the inner lining component of the door body 200 .

[0089] A freezing chamber is defined in the freezing chamber blister liner and is arranged below the refrigerating chamber 110 to freeze the food stored therein.

[0090] The middle beam member 120 is disposed between the refrigerating chamber 110 and the freezing chamber and connects the refrigerating chamber 110 and the freezing chamber.

[0091] In a specific arrangement, the middle beam component 120 is arranged between the refrigerating chamber 110 and the freezing chamber, and is extended along the width direction of the refrigeration device.

[0092] The middle beam component 120 is connected to the blister liner of the refrigerating chamber 110 and the blister liner of the freezing chamber to achieve the connection between the refrigerating chamber 110 and the freezing chamber.

[0093] The door body 200 is rotatably connected to the box body 100 to open or close the refrigerating chamber 110 .

[0094] The door body 200 is connected to the box body 100 at the exit of the refrigerating chamber 110 to realize opening or closing of the refrigerating chamber 110. The opening and closing of the door body 200 can facilitate the user to take things inside and outside the refrigerating chamber 110.

[0095] In some embodiments of the present application, a freezer door is further included, which is rotatably connected to the housing 100 and arranged at a position corresponding to the position of the freezer compartment to open or close the freezer compartment.

[0096] The door body 200 located at the refrigerating chamber 110 and the freezing door of the freezing chamber are arranged on the box body 100 one above the other.

[0097] In some embodiments of the present application, the door body 200 includes a door body 200 surface component, which is arranged outside the box body 100 and constitutes the outer surface of the door body 200;

[0098] The door body 200 lining component is arranged at the inner side of the box body 100 and constitutes the inner surface of the door body 200;

[0099] An upper end cover connected to the top position of the surface component of the door body 200 and the lining component of the door body 200;

[0100] The lower end cover 210 is connected to the bottom position of the surface component of the door body 200 and the inner part of the door body 200.

[0101] In some embodiments of the present application, in order to realize the rotational opening and closing of the door body 200 relative to the box body 100 , a hinge component 300 is provided at the position of the lower end cover 210 of the door body 200 .

[0102] Specifically, the hinge component 300 is assembled and fixed on the middle beam component 120 to connect the lower end cover 210 of the door body 200 and the middle beam component 120 .

[0103] The lifting component 400 is assembled on the hinge component 300 and includes: a spiral lifting part, and the spiral lifting part correspondingly includes:

[0104] A first spiral lifting part 410;

[0105] In some embodiments of the present application, the first spiral lifting portion 410 is a first spiral lifting section, which is arranged in a spiral shape and is located on one side of the lifting component 400 .

[0106] The second spiral lifting part 420 is arranged on both sides of the lifting component 400 opposite to the first spiral lifting part 410 and is connected to the first spiral lifting part 410 .

[0107] The second spiral lifting portion 420 is a second spiral lifting section formed on the lifting component 400 , which is arranged in a spiral shape, has a rotation direction opposite to that of the first spiral lifting portion 410 , and is arranged at the other side of the lifting component 400 .

[0108] The first spiral lifting section and the second spiral lifting section are both arranged spirally, and the two intersect each other at the end positions.

[0109] In some embodiments of the present application, the first spiral lifting segment and the second spiral lifting segment are respectively connected at the top position and the bottom position of the two spiral segments.

[0110] The first spiral lifting section and the second spiral lifting section are smoothly transitionally connected at the top position of the intersection;

[0111] The first spiral lifting section and the second spiral lifting section are butted against each other at the bottom of the intersection to form a bayonet.

[0112] The lifting and lowering fitting part 220 is formed on the lower end cover 210, is rotatably connected to the lifting component 400, and has a spiral fitting part that cooperates with the spiral lifting part;

[0113] During installation, the lower end cover 210 is assembled on the lifting component 400 through the lifting fitting portion 220 to achieve the rotation of the lower end cover 210 relative to the lifting component 400 .

[0114] Since the lifting component 400 is assembled and fixed on the hinge component 300 , and the hinge component 300 is fixed on the middle beam component 120 , the door body 200 driving the lower end cover 210 can be rotated relative to the box body 100 to open or close.

[0115] When the lifting and lowering fitting portion 220 is assembled on the lifting component 400 , the spiral fitting portion on the upper side thereof is correspondingly matched with the spiral lifting and lowering portion on the lifting component 400 .

[0116] In some embodiments of the present application, the shape of the spiral fitting portion is configured to match the shapes of the first spiral lifting portion 410 and the second spiral lifting portion 420 .

[0117] When the door body 200 is closed, the spiral fitting portion can be completely engaged in the first spiral lifting portion 410 and the second spiral lifting portion 420 .

[0118] When the door body 200 is opened, the spiral matching portion can perform spiral lifting and sliding along the spiral lifting portion as the door body 200 and the lower end cover 210 rotate, so as to ensure that the door body 200 can be opened normally and smoothly.

[0119] A limiting structure, formed on the lower end cover 210 and the hinge component, for limiting the door body 200;

[0120] By setting the limiting structure, the opening angle of the door body 200 can be limited to prevent the door body 200 from colliding with the box body 100 structure due to excessive opening angle.

[0121] Wherein, when the door opening angle of the door body 200 is less than or equal to the first door opening angle, the spiral fitting part slides upward along the first spiral lifting part 410 during the opening process of the door body 200, and when the door is closed, the spiral fitting part slides in the opposite direction along the spiral fitting part under the dead weight of the door body 200 to close;

[0122] When the opening angle of the door body 200 is greater than the first opening angle and less than or equal to the second opening angle, the lifting and lowering matching part 220 slides up along the first spiral lifting part 410 to the second spiral lifting part 420 and slides down along the second spiral lifting part 420 while being limited and maintained at the second opening angle by the limiting structure during the door opening process.

[0123] When the door opening angle of the door body 200 is within the first angle range, that is, when the door opening angle of the door body 200 is smaller than the first door opening angle, during the door opening process, the lifting and lowering matching part 220 only needs to slide along the first spiral lifting part 410 .

[0124] In some embodiments of the present application, the first door opening angle is 110 degrees, and the first angle range is 0-110 degrees.

[0125] That is, when the door opening angle is within the range of 0-110 degrees, the door body 200 rotates to drive the lower end cover 210 and the lifting and lowering matching part 220 formed on the lower end cover 210 to slide along the first spiral lifting part 410 to achieve the door opening.

[0126] When the door body 200 is opened to 110 degrees, the corresponding lifting matching portion 220 slides to the top position of the first spiral lifting portion 410 .

[0127] When opening the door, the lifting and lowering cooperation part 220 slides up along the first spiral lifting part 410 to open the door, and the first spiral lifting part 410 is a spiral lifting structure. In this way, after the external force acting on the door body 200 disappears, that is, when the user releases the door body 200 after taking out the food stored in the refrigerator chamber 110, the lifting and lowering cooperation part 220 formed on the lower end cover 210 will be driven by the gravity of both the door body 200 and the lower end cover 210 to automatically slide down along the first spiral lifting part 410, thereby realizing the automatic closing of the door body 200 and the automatic door closing function.

[0128] By arranging the first spiral lifting part 410 on the lifting component 400 to match the lifting matching part 220 matched therewith, by the lifting matching part 220 sliding along the first spiral lifting part 410 and by the length structure setting of the spiral lifting section of the first spiral lifting part 410, the door body 200 can be opened at a larger angle within the first door opening angle range, i.e., within the range of 0-110 degrees, and after opening within this angle range, the door body 200 can be automatically closed after the door body 200 is released. Compared with the method in the prior art that adopts a suction aid structure and can only be automatically closed after being opened about 5 degrees, the door opening angle is increased, which is convenient for users to take food;

[0129] When the door body 200 is opened to any angle between 0 and 110 degrees, it will automatically rebound and close the door body 200 automatically. When the user takes out the things, there is no need to close the refrigerator door, which improves the user experience.

[0130] When the opening angle of the door body 200 is greater than the first door opening angle and less than the second door opening angle, during the door opening process, the door body 200 drives the lower end cover 210 and the lifting and lowering matching part 220 to first slide along the first spiral lifting part 410, and then slide from the first spiral lifting part 410 to the second spiral lifting part 420 connected thereto, so as to achieve a large-angle door opening effect.

[0131] In some embodiments of the present application, the second door opening angle is 115 degrees, that is, when the door opening angle is between 110-115 degrees, the lifting and fitting part 220 will slide up from the first spiral lifting part 410 and then reach the top position of the first spiral lifting part 410, and continue to slide into the second spiral lifting part 420. Under the action of gravity of the door body 200, the lifting and fitting part 220 will continue to slide down along the second spiral lifting part 420, driving the door body 200 to continue to rotate and unfold relative to the box body 100.

[0132] In order to prevent the lifting matching part 220 from sliding too far along the second spiral lifting part 420, resulting in too large an opening angle of the door and interference with the box body 100, mutually cooperating limiting structures are provided at the hinge part 300 and the lower end cover 210 to limit the door body 200.

[0133] When the opening angle of the door body 200 exceeds the first opening angle, the lifting and matching part 220 will naturally slide down along the second spiral lifting part 420 under the action of the gravity of the door body 200, and the limiting structure can limit it so that the door body 200 remains at the second opening angle position and will not continue to open.

[0134] That is, when the opening angle of the door body 200 is within the range of 110-115 degrees, the door body 200 can eventually be maintained at the maximum door opening angle, that is, the second door opening angle position, through the limiting structure.

[0135] When the door body 200 is opened to any angle between 110 and 115 degrees, the door body 200 can be opened to the second door opening angle by its own weight. Through the limiting structure between the lower end cover 210 and the hinge part 300, the door body 200 can stay in the original position, which can meet the user's needs of opening the door body 200 to store items for a long time, thereby improving the user experience.

[0136] When the door body 200 is opened to any angle between 110 and 115 degrees, the door body 200 will stay at the second door opening angle. At this time, an initial force needs to be provided to the door body 200 to close the door, so that the door body 200 can be closed.

[0137] When the door body 200 is opened at an angle of 110-115 and needs to be closed, the initial force provided to the door body 200 only needs to enable the lifting and lowering matching part 220 to slide from the second spiral lifting part 420 to the top position of the first spiral lifting part 410. After the lifting and lowering matching part 220 slides to the first spiral lifting part 410, it can be automatically closed by the door body 200's own gravity. Therefore, when closing the door, only a smaller closing force needs to be provided to close the door body 200, and the door closing operation is labor-saving and convenient.

[0138] In this embodiment, the refrigeration device is provided with a first spiral lifting part 410 and a second spiral lifting part 420 with two spiral arrangements on the lifting component 400, and a corresponding lifting matching part 220 is provided, so that the door body 200 can have different opening modes when it is opened.

[0139] When the door opening angle is less than the first door opening angle, it can realize automatic rebound closing, and the user does not need to close the door body 200 after taking something;

[0140] When the door opening angle is greater than the first door opening angle and smaller than the second door opening angle, the door body 200 is kept open at the second door opening angle through the limiting structure, which can facilitate the user to open the door for a long time to store items, meet the different usage needs of users, and improve the user's usage experience in multiple scenarios.

[0141] In some embodiments of the present application, the spiral fitting portion includes:

[0142] The first spiral portion 221 is adapted to cooperate with the first spiral lifting portion 410;

[0143] The second spiral portion 222 is used to match with the second spiral lifting portion 420 and smoothly connect with the first spiral portion 221 .

[0144] The first spiral portion 221 is a first spiral segment, which is adapted to the spiral angle of the first spiral lifting portion 410 .

[0145] When the opening angle of the door body 200 is less than or equal to the first door opening angle, the first spiral portion 221 can slide in contact with the first spiral lifting portion 410 .

[0146] When closed, it is completely attached to the first spiral lifting part 410 .

[0147] The second spiral portion 222 is a second spiral segment, which is adapted to the second spiral lifting portion 420 .

[0148] When the door opening angle of the door body 200 is greater than the first door opening angle and less than the second door opening angle, the lifting and lowering matching portion 220 slides downward along the second spiral lifting portion 420 through the second spiral portion 222 .

[0149] When the door body 200 is in a closed state, the second spiral portion 222 is arranged in close contact with a position above the second spiral lifting portion 420 .

[0150] In some embodiments of the present application, the lifting component 400 further includes a smooth connection portion 430, one end of the smooth connection portion 430 is smoothly transitionally connected to the first spiral lifting portion 410, and the other end of the smooth connection portion 430 is smoothly transitionally connected to the second spiral lifting portion 420;

[0151] The smooth connection portion 430 can realize a smooth connection between the first spiral lifting portion 410 and the second spiral lifting portion 420 , and the lifting matching portion 220 can smoothly slide from the first spiral lifting portion 410 to the second spiral lifting portion 420 when sliding.

[0152] In some embodiments of the present application, the smooth connection portion 430 is a smooth connection section, which is connected and arranged at the top connection position of the first spiral lifting portion 410 and the second spiral lifting portion 420 .

[0153] The smooth connection section includes a first guide section, a middle section, and a second guide section connected to the middle section, wherein the first guide section is smoothly connected to the end of the first spiral lifting portion 410;

[0154] The end of the second guide section is smoothly connected to the end of the second spiral lifting portion 420 .

[0155] When the door body 200 is opened, it slides along the top position of the upper slide of the first spiral lifting part 410 and then slides into the second spiral lifting part 420. Therefore, the smooth transition part is arranged at the top connecting position of the first spiral lifting part 410 and the second spiral lifting part 420 to play a guiding transition role.

[0156] The first spiral lifting portion 410 gradually increases in height along the direction from away from the smooth connection portion 430 to close to the smooth connection portion 430;

[0157] The height of the second spiral lifting portion 420 gradually decreases along a direction from approaching the smooth connecting portion 430 to moving away from the smooth connecting portion 430 .

[0158] The first spiral lifting part 410 is arranged to have a greater height as it is closer to the smooth connection part 430, so as to ensure that the lifting matching part 220 slides upward along the first spiral lifting part 410 when the door is opened, so as to ensure that the door body 200 can be automatically closed under the action of its own weight;

[0159] The second spiral lifting part 420 is arranged to have a greater height as it is closer to the smooth connection part 430 and a smaller height as it is farther away from the transition connection part 330. This can be used to ensure that when the door body 200 is opened wider, the door body 200 can automatically slide down and open along the second spiral lifting part 420 by its own weight, thereby ensuring smooth door opening.

[0160] In some embodiments of the present application, the first spiral lifting part 410 has a first spiral lifting surface 411, and the second spiral lifting part 420 has a second spiral lifting surface 421, and the height of the highest point of the first spiral lifting surface 411 is higher than the height of the highest point of the second spiral lifting surface 421.

[0161] Setting the highest point of the first spiral lifting surface 411 higher than the highest point of the second spiral lifting surface 421 can ensure that the lifting matching part 220 can slide downward along the second spiral lifting part 420 under the action of gravity of the door body 200 to ensure the opening of the door body 200.

[0162] If the second spiral lifting surface 421 is set to have a highest point higher than the first spiral lifting surface 411, the lifting matching part 220 cannot slide down by its own weight when sliding to the second spiral lifting surface 421, and the door cannot continue to open.

[0163] In some embodiments of the present application, the highest point of the first spiral lifting surface 411 of the first spiral lifting portion 410 may be set to be equal to the highest point of the second spiral lifting surface 421 of the second spiral lifting portion 420 .

[0164] In some embodiments of the present application, an insertion portion 250 is formed on the lifting and lowering fitting portion 220;

[0165] The lifting component 400 includes a rotating portion 440 , and the rotating portion 440 is inserted into the inserting portion 250 to achieve a rotational connection between the lifting component 400 and the lifting matching portion 220 .

[0166] In some embodiments of the present application, the lifting and lowering fitting portion 220 is a lifting and lowering fitting sleeve, and the inserting portion 250 is an inserting cavity formed in the lifting and lowering fitting sleeve.

[0167] The first spiral portion 221 is a first spiral segment formed on one side of the lifting and lowering sleeve, and the second spiral portion 222 is a second spiral segment arranged on the other side of the lifting and lowering sleeve.

[0168] The rotating portion 440 is a rotating shaft body, which is arranged at a middle position of the lifting component 400 , and the first spiral lifting portion 410 and the second spiral lifting portion 420 are spirally arranged along the rotating portion 440 .

[0169] During assembly, the rotating shaft and the insertion cavity of the lifting fitting sleeve are inserted and matched to achieve relative rotation between the lifting fitting portion 220 and the lifting component 400 .

[0170] After being assembled in place, the first spiral portion 221 fits in with the first spiral lifting portion 410 , and the second spiral portion 222 fits in with the second spiral lifting portion 420 .

[0171] In some embodiments of the present application, the first spiral lifting portion 410 is arranged in a circumferential spiral along the rotating portion 440;

[0172] The second spiral lifting part 420 is arranged in a spiral direction along the rotating part 440.

[0173] Along the circumferential direction of the rotating portion 440 , the length of the first spiral lifting portion 410 is greater than the length of the second spiral lifting portion 420 .

[0174] When opening the door within the first door opening angle range, the lifting and lowering matching part 220 slides along the first spiral lifting part 410 to open the door. By reasonably setting the length of the spiral section of the first spiral lifting part 410, it can be ensured that the door body 200 can be opened at a larger angle within a certain angle range.

[0175] In order to enable the door body 200 to automatically close within a larger door opening angle range, the first spiral lifting part 410 can be set to a longer length during setting. Since the door opening angle range corresponding to the second door opening angle is smaller, it only needs to slide a short distance along the second spiral lifting part 420. Therefore, during setting, the length of the first spiral lifting part 410 is set to be longer than the length of the second spiral lifting part 420.

[0176] In some embodiments of the present application, the lower end cover 210 includes:

[0177] The end cover body is provided with a lifting and lowering fitting portion 220 integrally formed therewith;

[0178] In order to simplify the manufacturing process, the end cover body and the lifting and lowering matching part 220 are integrally formed by an injection mold during molding, and the overall structure is simpler.

[0179] By directly molding the lifting and lowering fitting part 220 into the end cover body, the lifting and lowering fitting part 220 can be hidden inside the end cover body, thereby enhancing the overall aesthetics.

[0180] and an insertion channel 230 formed on the end cover body for inserting the lifting component 400, wherein the insertion channel 230 corresponds to the position of the lifting matching portion 220;

[0181] The insertion channel 230 is directly formed on the end cover body, and is used for inserting and assembling the lifting component 400 , so that the lifting component 400 can pass through the insertion channel 230 to be assembled with the internal lifting matching portion 220 .

[0182] Due to the provision of the insertion channel 230, during assembly, the lifting component 400 is inserted into the lifting matching portion 220 arranged in the end cover body after passing through the internal insertion channel 230, and the matching connection structure between the lifting component 400 and the lifting matching portion 220 is completely built into the end cover body, realizing a hidden arrangement. The matching connection structure of the two cannot be seen from the outside, and the overall structure is simpler and more aesthetically pleasing.

[0183] In some embodiments of the present application, the lower end cover 210 includes:

[0184] An end cover body, on which a matching component is assembled, and on which the lifting matching portion 220 is formed;

[0185] The matching component is a matching sleeve, which is formed separately from the end cover body, and a lifting matching portion 220 is formed inside the matching sleeve. The matching sleeve is installed in the end cover body by interference fit to match the lifting component 400.

[0186] And an insertion channel 230 is formed on the end cover body and is used for inserting the lifting component 400 . The insertion channel 230 corresponds to the position of the lifting matching portion 220 .

[0187] During assembly, the lifting component 400 is inserted into the matching component through the insertion channel 230 .

[0188] In some embodiments of the present application, the hinge component 300 includes:

[0189] A hinge body, on which an assembly portion 310 is formed for assembling the lifting component 400;

[0190] The assembly portion 310 is an assembly hole provided through the hinge body. During installation, the lifting component 400 is inserted into the assembly hole with interference fit to achieve a tight connection with the hinge body.

[0191] A reinforcement portion 320, arranged around the assembling portion 310;

[0192] The reinforcement portion 320 is an annular reinforcement rib, which is used to enhance the strength of the assembly portion 310 .

[0193] The connecting portion 330 is formed by bending from the hinge body, and a locking portion 331 for cooperating and connecting with the middle beam component 120 is arranged on the upper side thereof.

[0194] The connecting portion 330 is a connecting arm bent from the hinge body, which is arranged perpendicular to the hinge body. The locking portion 331 is a locking hole opened on the connecting arm. A plurality of locking holes can be provided for locking the hinge body to the middle beam component 120.

[0195] During connection, the locking screw passes through the locking hole and is screwed into the middle beam component 120 to firmly connect the hinge body and the middle beam component 120 .

[0196] In some embodiments of the present application, the limiting structure includes:

[0197] A limiting protrusion 240 is formed on the lower end cover 210;

[0198] And a locking protrusion 340 is formed on the hinge component 300 and is located on the rotation path of the limiting component, and is used to be locked on the limiting protrusion 240 to limit the door body 200 when the door body 200 rotates to the second door opening angle.

[0199] In some embodiments, a limiting element is provided on the lower end cover 210 , and the limiting element is fixed to the bottom surface of the lower end cover 210 by screws or bolts.

[0200] The limiting element is provided with a limiting protrusion 240 extending from the upper side thereof.

[0201] In some embodiments of the present application, the limiting protrusion 240 is formed by extending from the end cover body, and is integrally injection molded with the end cover body.

[0202] In some embodiments of the present application, an arc-shaped guide portion is formed on the outer side of the hinge body where the lifting component 400 is assembled, and the locking protrusion 340 is formed at one side of the arc-shaped guide portion.

[0203] When the door body 200 and the lower end cover 210 rotate, the limiting protrusion 240 on the lower end cover 210 can rotate along the arc direction of the arc-shaped guide portion. When it rotates to a position on one side of the arc-shaped guide portion, it will be blocked and limited by the locking protrusion 340 located on its rotation path. At this time, the door body 200 cannot continue to rotate, thereby realizing the rotation limitation of the door body 200.

[0204] By means of the mutually cooperating limiting structures provided on the lower end cover 210 and the hinge component 300, the rotation angle of the door body 200 is limited, so that the door body 200 remains at the second door opening angle position, ensuring that the door body 200 can remain in this position after opening, which is convenient for users.

[0213] When the opening angle of the door body 200 is less than the first door opening angle, the spiral matching part slides upward along the spiral part when the door is opened, and when the door is closed, the spiral matching part slides in the opposite direction along the spiral part under the dead weight of the door body 200 and closes;

[0214] When the opening angle of the door body 200 is greater than the first door opening angle, the spiral matching portion first slides up and then slides down along the spiral portion, and is limited by the limiting structure.

[0215] In some embodiments of the present application, the spiral portion includes a first spiral lifting portion 410 and a second spiral lifting portion 420. The lifting and lowering matching portion 220 slides up along the first spiral lifting portion 410 to achieve opening within the first door opening angle, and automatically closes by the door body 200's own weight after the force of the door body 200 is removed.

[0218] The first spiral lifting part 410 and the second spiral lifting part 420 are smoothly connected and the top end of the first spiral lifting part 410 and the bottom end of the second spiral lifting part 420 are connected;

[0219] The third spiral lifting part and the fourth spiral lifting part are arranged on the other side of the lifting component 400 and are connected to each other. The top end of the third spiral lifting part is connected to the top end of the second spiral lifting part 420, and the fourth spiral lifting part is connected to the bottom end of the third spiral lifting part.

[0220] The lifting and lowering fitting part 220 may also be configured as a plurality of spiral fitting section structures adapted thereto.

[0221] When opening the door, the lifting and matching part 220 can slide upward along the first spiral lifting part 410 and the second spiral lifting part 420 to achieve the first door opening angle, and the door body 200 can automatically close the door by its own weight;

[0222] The door body 200 is opened to the second door opening angle by sliding the lifting matching part 220 along the third spiral lifting part, and is limited by the limiting structure.

[0223] Alternatively, the lifting matching part 220 slides along partial sections of the third spiral lifting part and the fourth spiral lifting part to open the door body 200 to the second door opening angle.
