[0051] As shown in Figures 1 to 9 , the present embodiment provides a vertical beam assembly 10 for a refrigerator 1 door body 20, the vertical beam assembly 10 including a vertical beam body 100, an extension structure 200, a rotation shaft 300, and a linkage assembly 400. The vertical beam body 100 has a hollow portion 110 formed at an end thereof in a length direction thereof. The extension structure 200 moves in the length direction of the vertical beam body 100 to extend out of the hollow portion 110 or to retract into the hollow portion 110.

[0052] The rotation shaft 300 is rotatably provided in the vertical beam body 100, the rotation shaft 300 being configured to rotatably provide the vertical beam body 100 on the refrigerator 1 door body 20, the rotation shaft 300 having at least one limit pin 330 on an outer circumferential wall thereof.

[0053] The linkage assembly 400 is arranged in the vertical beam body 100, and the linkage assembly 400 is configured to be movable along the length direction of the vertical beam body 100, so as to make the telescopic structure 200 extend out of the hollow portion 110 or retract into the hollow portion 110. The linkage assembly 400 has a bearing portion 414. The bearing portion 414 is in a circular arc shape, the bearing portion 414 is sleeved outside the outer peripheral wall of the rotating shaft 300, and the bearing portion 414 has at least one guide portion 415 extending along the circumferential direction and the axial direction of the bearing portion 414. The at least one guide portion 415 is used for one-to-one corresponding arrangement of the at least one limit pin 330, and is configured to make the linkage assembly 400 move along the length direction of the vertical beam body 100 in the case that the rotating shaft 300 rotates.

[0054] In the embodiment, the number of the door bodies 20 of the refrigerator 1 is not limited, and can be selected as required. As a specific embodiment, as shown in Figure 1 and Figure 2 , the refrigerator 1 is a three-door refrigerator 1.

[0055] In the embodiment, the door body 20 of the refrigerator 1 rotatably connected with the vertical beam assembly 10 is not limited, and can be selected as required. As a specific embodiment, as shown in Figure 2 and Figure 3 , the vertical beam body 100 is connected with the left door body 20 of the refrigerator 1. Obviously, this is only exemplary and not the only one. Among them, Figure 2 in order to fully show the connection between the left door body 20 of the refrigerator 1 and the vertical beam body 100, the right door body 20 of the refrigerator 1 is not shown in Figure 2 .

[0056] In the process of opening the left door body 20, the vertical beam body 100 rotates out of the refrigerator 1 along with the left door body 20. In the process of closing the left door body 20, the vertical beam body 100 rotates into the refrigerator 1 along with the left door body 20. In the case that the door body 20 of the refrigerator 1 is closed, as shown in Figure 1 and Figure 2 , the vertical beam body 100 is located between the left door body 20 and the right door body 20 to prevent cold air from leaking out between the left door body 20 and the right door body 20.

[0057] In the embodiment, the end of the vertical beam body 100 along the length direction of the vertical beam body 100 can be the upper end of the vertical beam body 100 and / or the lower end of the vertical beam body 100. As a specific embodiment, as shown in Figures 3 to 6 , the end of the vertical beam body 100 along the length direction of the vertical beam body 100 refers to the lower end of the vertical beam body 100. Obviously, this is only exemplary and not the only one.

[0058] In the embodiment, the external shape of the hollow portion 110 and the internal shape of the hollow portion 110 are not limited, and can be selected as required. As a specific embodiment, as shown in Figure 13As shown, the outer shape of the hollow portion 110 and the inner shape of the hollow portion 110 are both arc-shaped, which facilitates the rotation of the vertical beam body 100 into or out of the refrigerator 1. It is obvious that this is only exemplary and not the only one.

[0059] In the present embodiment, the specific shape of the telescopic structure 200 is not limited and can be selected as needed. For example, Figure 10 As shown, as a specific embodiment, the specific shape of the telescopic structure 200 is arc-shaped, and the outer peripheral wall of the telescopic structure 200 is adapted to the inner wall of the hollow portion 110, that is, the outer peripheral wall of the telescopic structure 200 is attached to the inner peripheral wall of the hollow portion 110. As shown, Figure 6 As shown, the telescopic structure 200 moves up and down along the inner wall of the hollow portion 110. The telescopic structure 200 of this shape has a good wind-blocking effect.

[0060] In the present embodiment, the rotating shaft 300 is rotatably arranged in the vertical beam body 100. During the opening of the door body 20 of the refrigerator 1, the vertical beam body 100 rotates around the rotating shaft 300 to rotate out of the refrigerator 1. During the closing of the door body 20 of the refrigerator 1, the vertical beam body 100 rotates around the rotating shaft 300 to rotate into the refrigerator 1. In the present embodiment, the angle of rotation of the vertical beam body 100 during the opening or closing of the door body 20 of the refrigerator 1 is not limited and can be selected as needed.

[0061] As a specific embodiment, the rotating shaft 300 is rotatably arranged on one side of the vertical beam body 100. As shown, Figures 2 to 3 As shown, the left side of the vertical beam body 100 is rotatably arranged on the left door body 20 of the refrigerator 1, and the rotating shaft 300 is rotatably arranged in the left side of the vertical beam body 100. It is obvious that this is only exemplary and not the only one.

[0062] The outer peripheral wall of the rotating shaft 300 has at least one limit pin 330, as a specific embodiment, as shown, Figure 9 As shown, the outer peripheral wall of the rotating shaft 300 has two limit pins 330. It is obvious that this is only exemplary and not the only one, for example, the number of limit pins 330 can be one, three, four or more. In the present embodiment, the limit pin 330 and the rotating shaft 300 can be integrally formed or in a separate structure. The shape of the limit pin 330 is not limited and can be selected as needed.

[0063] The linkage assembly 400 is arranged in the vertical beam body 100, and the linkage assembly 400 is configured to be movable only in the length direction of the vertical beam body 100. That is, the linkage assembly 400 can only move in the longitudinal direction of the vertical beam body 100, that is, the linkage assembly 400 can only move up and down.

[0064] In the embodiment, the specific components included in the linkage assembly 400 are not limited, and can be selected as required. As a specific embodiment, as shown in Figure 7 The linkage assembly 400 includes a linkage shaft 410 and a linkage structure 430. In the embodiment, the specific manner in which the linkage assembly 400 extends or retracts the telescopic structure 200 from or into the hollow portion 110 is not limited. For example, the linkage assembly 400 can directly drive the telescopic structure 200 to move up and down, or the linkage assembly 400 can indirectly drive the telescopic structure 200 to move up and down.

[0065] In the embodiment, the linkage assembly 400 has a bearing portion 414, which is in the shape of a circular arc. In the embodiment, the specific shape of the bearing portion 414 is not limited, for example, the bearing portion 414 can include a circular arc, can include a semicircular cylinder, or can include a cylinder. As a specific embodiment, as shown in Figure 7 and Figure 8 The bearing portion 414 includes a cylinder, which is obviously only exemplary and not the only one.

[0066] In the embodiment, the spacing between the inner circumferential wall of the bearing portion 414 and the outer circumferential wall of the rotating shaft 300 is not limited, and can be selected as required. As shown in Figure 6 The spacing between the inner circumferential wall of the bearing portion 414 and the outer circumferential wall of the rotating shaft 300 is small and can be ignored.

[0067] In the embodiment, the specific number of the guide portions 415 is not limited, and can be selected as required. As a specific embodiment, as shown in Figures 6 to 8 The number of the guide portions 415 is two. Obviously, this is only exemplary and not the only one, for example, the number of the guide portions 415 can be one, three, four, or more.

[0068] In the embodiment, the guide portions 415 and the bearing portion 414 can be integrally formed or in a split structure. For example, the guide portions 415 can be blind grooves or through grooves formed on the bearing portion 414.

[0069] In the embodiment, the specific shape of the guide portions 415 is not limited, as shown in Figures 7 to 8 The guide portions 415 can extend along the circumferential direction and the axial direction of the bearing portion 414. As shown in Figure 8 Each guide portion 415 includes a first segment 4151, an intermediate segment 4152, and a second segment 4153 connected in sequence along the extension direction thereof, the first segment 4151 and the second segment 4153 are horizontal segments, and the intermediate segment 4152 is inclined, wherein the first segment 4151 is close to the telescopic structure 200. Obviously, this is only exemplary and not the only one.

[0070] In the process of rotating the rotating shaft 300, the linkage assembly 400 cannot rotate, so the linkage assembly 400 moves along the length direction of the vertical beam body 100 under the cooperation of the limiting pin 330 and the guide part 415.

[0071] Specifically, in the process of closing the door body 20 of the refrigerator 1, the limiting pin 330 moves from the first section 4151 to the second section 4153. The linkage assembly 400 moves towards the telescopic structure 200, i.e. moves downwards. The telescopic structure 200 moves downwards to extend from the hollow part 110 to achieve the air blocking effect.

[0072] In the process of opening the door body 20 of the refrigerator 1, the limiting pin 330 moves from the second section 4153 to the first section 4151. The linkage assembly 400 moves away from the telescopic structure 200, i.e. moves upwards, and the telescopic structure 200 retracts into the hollow part 110. This can reduce the friction of the telescopic structure 200 so that the vertical beam body 100 rotates out of the refrigerator 1.

[0073] The vertical beam assembly 10 provided in the embodiment can naturally extend the telescopic structure 200 to achieve the air blocking effect when the door body 20 of the refrigerator 1 is closed. The vertical beam assembly 10 can naturally retract the telescopic structure 200 when the door body 20 of the refrigerator 1 is opened.

[0074] In the embodiment, the angle through which the vertical beam body 100 rotates is not limited in the process of closing the door body 20 of the refrigerator 1 or in the process of opening the door body 20 of the refrigerator 1, and can be selected as required. As a specific embodiment, as shown in Figs. 1 and 2, the vertical beam body 100 rotates 90° counterclockwise in the process of closing the door body 20 of the refrigerator 1. The vertical beam body 100 rotates 90° clockwise in the process of opening the door body 20 of the refrigerator 1. Figure 7 and Figure 8 The vertical beam assembly 10 provided in the embodiment can naturally extend the telescopic structure 200 to achieve the air blocking effect when the door body 20 of the refrigerator 1 is closed. The vertical beam assembly 10 can naturally retract the telescopic structure 200 when the door body 20 of the refrigerator 1 is opened.

[0075] The vertical beam assembly 10 provided in the embodiment can naturally extend the telescopic structure 200 to achieve the air blocking effect when the door body 20 of the refrigerator 1 is closed. The vertical beam assembly 10 can naturally retract the telescopic structure 200 when the door body 20 of the refrigerator 1 is opened.

[0076] In other embodiments, each guide part 415 is a groove formed in the peripheral wall of the bearing part 414. This makes the vertical beam assembly 10 simple in structure.

[0077] In some other embodiments, each guide portion 415 corresponds to a central angle ranging from 80° to 100°. That is, the vertical beam body 100 rotates through an angle ranging from 80° to 110° during the process of opening or closing the door body 20 of the refrigerator 1. That is, during the process of opening and closing the door body 20 of the refrigerator 1, the vertical beam body 100 rotates through an angle ranging from 80° to 110° to rotate out of or into the refrigerator 1 from within the refrigerator 1. That is, the limiting pin 330 moves from the second segment 4153 to the first segment 4151 or from the first segment 4151 to the second segment 4153, and the vertical beam body 100 rotates through an angle ranging from 80° to 110° during which the door body 20 of the refrigerator 1 completes the opening and closing conversion.

[0078] As shown in Figure 1 and Figure 2 , if the vertical beam body 100 rotates through a too small angle, the vertical beam body 100 will be interfered by the structure of the right door body 20. That is, the left door body 20 cannot be opened alone, and the left door body 20 can be opened only after the right door body 20 is opened. If the vertical beam body 100 rotates through a too large angle, the vertical beam body 100 is not easily guided into the refrigerator 1 when the door body 20 of the refrigerator 1 is converted from the open state to the closed state. As a specific embodiment, as shown in Figures 14 to 16 , the vertical beam body 100 rotates through an angle of 90° during the process of opening and closing the door body 20 of the refrigerator 1.

[0079] In some other embodiments, each guide portion 415 includes a first segment 4151, an intermediate segment 4152 and a second segment 4153 connected in sequence along the extension direction thereof, the first segment 4151 is close to the telescopic structure 200, the first segment 4151 is a horizontal segment, and the intermediate segment 4152 is arranged obliquely.

[0080] During the process of closing the door body 20 of the refrigerator 1, the limiting pin 330 moves from the first segment 4151 to the second segment 4153. The first segment 4151 is a horizontal segment, that is, the position of the linkage assembly 400 and the telescopic structure 200 does not change during the movement of the limiting pin 330 in the first segment 4151. That is, during this process, the linkage assembly 400 does not move along the length direction of the vertical beam body 100. That is, during the process of closing the door body 20 of the refrigerator 1, the telescopic structure 200 does not extend out of the hollow portion 110 during the early stage of the rotation of the vertical beam body 100. This reduces the friction between the telescopic structure 200 and the refrigerator 1, facilitating the rotation of the vertical beam body 100 into the refrigerator 1.

[0081] During the opening process of the door body 20 of the refrigerator 1, the limit pin 330 moves from the second section 4153 to the first section 4151. When the door body 20 of the refrigerator 1 is open, the vertical beam main body 100 loses its restraint. That is, the vertical beam main body 100 may rotate due to accidental touch, which makes it difficult to close the door body 20. The first section 4151 is located at the lower end, and the first section 4151 is a horizontal section, and the middle section 4152 is an inclined section, which can prevent the random rotation of the vertical beam main body 100 to ensure the smooth closing of the door body 20 of the refrigerator 1.

[0082] In some other embodiments, the first section 4151 is close to the telescopic structure 200, and the range of the central angle corresponding to the first section 4151 is 10° to 20°. During the closing process of the door body 20 of the refrigerator 1, during the first 10° to 20° of rotation of the rotating shaft 300, the limit pin 330 is always located in the first section 4151. That is, during this process, the linkage assembly 400 does not move along the length direction of the vertical beam main body 100. That is, during the closing process of the door body 20 of the refrigerator 1, during the first 10° to 20° of rotation of the vertical beam main body 100, the telescopic structure 200 does not extend out of the hollow part 110. This reduces the friction between the telescopic structure 200 and the refrigerator 1 and facilitates the rotation of the vertical beam main body 100 into the refrigerator 1.

[0083] In some other embodiments, as Figures 6 to 7 shown, the shape of the bearing part 414 is cylindrical and is sleeved on the rotating shaft 300. At least one guiding part 415 includes a first guiding part 415 and a second guiding part 415 which are oppositely arranged. At least one limit pin 330 includes a first limit pin 330 and a second limit pin 330 arranged along the radial direction of the rotating shaft 300. The first limit pin 330 and the second limit pin 330 are respectively arranged in the first guiding part 415 and the second guiding part 415. This makes the force on the linkage assembly 400 and the telescopic structure 200 more balanced.

[0084] In some other embodiments, the linkage assembly 400 further includes a linkage shaft 410 and a first spring 420. The linkage shaft 410 is arranged in the vertical beam main body 100, has a bearing part 414, and extends into the hollow part 110 from the end of the vertical beam main body 100 through the rotating shaft 300. The first spring 420 is sleeved on the linkage shaft 410, and its two ends are respectively used to connect the end of the vertical beam main body 100 and the bearing part 414, and is configured to be compressed when the telescopic structure 200 extends out of the hollow part 110.

[0085] In this embodiment, the linkage assembly 400 includes a linkage shaft 410, and the linkage shaft 410 is used for the first spring 420 to be sleeved thereon. The linkage shaft 410 is used to prevent problems such as uneven force or inclination of the first spring 420. In this embodiment, the type of the linkage shaft 410 is not limited. For example, the linkage shaft 410 can be a circular shaft or a special-shaped shaft.

[0086] The first spring 420 is configured to be compressed when the telescopic structure 200 extends out of the hollow portion 110. That is, when the linkage shaft 410 moves downward, the first spring 420 is compressed to start storing energy. When the telescopic structure 200 retracts into the hollow portion 110, that is, when the linkage shaft 410 moves upward and the linkage shaft 410 moves toward the rotating shaft 300, the compressed first spring 420 provides an upward force to the linkage shaft 410 to enable the linkage shaft 410 to move upward.

[0087] In some other embodiments, the vertical beam assembly 10 for the door body 20 of the refrigerator 1 further includes a plurality of second springs 500. The plurality of second springs 500 are uniformly arranged within the telescopic structure 200 and are used to connect the end of the vertical beam main body 100 and the telescopic structure 200, and are configured to be compressed when the telescopic structure 200 retracts into the hollow portion 110.

[0088] The plurality of second springs 500 are configured to be compressed when the telescopic structure 200 retracts into the hollow portion 110. When the telescopic structure 200 extends out of the hollow portion 110, the compressed plurality of second springs 500 provide a force to the telescopic structure 200 to enable the telescopic structure 200 to extend out of the hollow portion 110. The plurality of second springs 500 are uniformly arranged so that the telescopic structure 200 is uniformly stressed, enabling the telescopic structure 200 to extend or retract smoothly into the hollow portion 110 multiple times.

[0089] In some other embodiments, the outer peripheral wall of the bearing portion 414 has at least one limiting portion 412, and the at least one limiting portion 412 cooperates with the vertical beam main body 100 to prevent the bearing portion 414 from rotating.

[0090] In this embodiment, the shape of the limiting portion 412 is not limited. The limiting portion 412 can prevent the abutting portion from rotating and enable the limiting portion 412 to move along the length direction of the vertical beam main body 100. As a specific embodiment, as Figure 8 shown, the shape of the limiting portion 412 is strip-shaped. Obviously, this is only exemplary and not the only one.

[0091] In this embodiment, the number of the limiting portions 412 is not limited and can be selected according to needs. As a specific embodiment, as Figure 8 shown, the number of the limiting portions 412 is 4, and they are uniformly distributed along the outer peripheral wall of the abutting portion.

[0092] In some other embodiments, the linkage component 400 extends from the rotating shaft 300 to the middle part of the telescopic structure 200 so that the telescopic structure 200 can extend out of the hollow part 110 or retract into the hollow part 110. In this embodiment, the specific manner in which the linkage component 400 extends to the middle part of the telescopic structure 200 is not limited and can be selected as needed. The linkage component 400 extending to the middle part of the telescopic structure 200 makes the telescopic structure 200受力均匀.

[0093] In some other embodiments, the linkage component 400 includes a linkage structure 430. The linkage structure 430 moves along the length direction of the vertical beam main body 100 following the linkage component 400. The linkage structure 430 is disposed within the hollow part 110 and has a force - applying section 431. The telescopic structure 200 has a receiving portion 210 that protrudes towards the end of the vertical beam main body 100. The force - applying section 431 is received within the receiving portion 210 to enable the telescopic structure 200 to extend out of or retract into the hollow part 110.

[0094] In this embodiment, the specific shapes of the linkage structure 430 and the force - applying section 431 are not limited and can be selected as needed. As Figure 7 shown, the linkage structure 430 is an L - shaped plate, and the force - applying section 431 is a long - strip - shaped plate. Obviously, this is only exemplary and not the only one.

[0095] As Figure 10 shown, the telescopic structure 200 has a receiving portion 210 that protrudes towards the end of the vertical beam main body 100. That is, the telescopic structure 200 has a receiving portion 210 that protrudes upwards. The force - applying section 431 is disposed within the receiving portion 210 to enable the telescopic structure 200 to extend out of or retract into the hollow part 110. This connection method is simple and easy to disassemble and replace.

[0096] In some other embodiments, both the receiving portion 210 and the force - applying section 431 are in a long - strip shape, and the receiving portion 210 and the force - applying section 431 are arranged transversely along the vertical beam main body 100. That is, the receiving portion 210 and the force - applying section 431 extend from one side of the vertical beam main body 100 to the other side of the vertical beam main body 100. That is, the receiving portion 210 and the force - applying section 431 extend from the left side of the vertical beam main body 100 to the right side of the vertical beam main body 100. This makes the telescopic structure 200受力均匀.

[0097] In some other embodiments, the force - applying section 431 is configured to抵触 the receiving portion 210 to drive the telescopic structure 200 to move when the telescopic structure 200 retracts into the hollow part 110. That is, as Figure 7 shown, at this time, the force - applying section 431抵触 the upper side of the receiving portion 210 and drives the telescopic structure 200 to move upwards. That is, the force - applying section 431 is the power for the telescopic structure 200 to move upwards.

[0098] It should be noted that the phrase "受力均匀" in Chinese is not accurately translated in the above content. A more accurate translation could be "receive uniform force". However, according to the requirements, the original text is retained as much as possible.In some other embodiments, the force-applying segment 431 is configured to disengage from the contact receiving portion 210 when the telescopic structure 200 extends from the hollow portion 110. The force-applying segment 431 first moves downward to disengage from the upper side of the contact receiving portion 210, and the telescopic structure 200 moves downward under the force of the second spring 500 to extend from the hollow portion 110. That is, as... Figure 10 As shown, the distance between the upper and lower sides of the receiving portion 210 defines the range of vertical movement of the linkage assembly 400 and the telescopic structure 200. This method of controlling the movement of the telescopic structure 200 by the linkage assembly 400 ensures that the telescopic structure 200 is subjected to uniform force.

[0099] In some other embodiments, the linkage structure 430 further includes a transmission section 432, the two ends of which are connected to the force-applying section 431 and the linkage shaft 410, respectively. In this embodiment, the shape of the transmission section 432 is not limited and can be selected as needed. As a specific embodiment, such as Figure 7 As shown, the shape of the conductive section 432 is plate-shaped. Obviously, this is only an example and not the only one.

[0100] In some other embodiments, the connecting shaft 410 extends two symmetrical locking portions 413, and the transmission section 432 is locked between the two locking portions 413. In this embodiment, the specific shape of the locking portions 413 is not limited and can be selected as needed. Figure 8 As shown, the locking part 413 is a claw extending from the connecting shaft 410, and the transmission section 432 is locked between the two claws. Furthermore, the middle part of the transmission section 432 is fixed to the connecting shaft 410 by a screw, which further prevents the connecting shaft 410 from rotating.

[0101] In some other embodiments, the vertical beam body 100 forms an arc-shaped connecting structure 120 at its length end. The vertical beam assembly 10 also includes a first fixing seat 600, which is disposed at the opening 30 of the refrigerator. The first fixing seat 600 has an arc-shaped, forward-facing first guide groove 610. The first fixing seat 600 is used to guide the connecting structure 120 along the inner sidewall of the first guide groove 610 into or out of the first guide groove 610 during the opening and closing of the refrigerator door 20.

[0102] In this embodiment, an arc-shaped connecting structure 120 is formed at the opposite ends of the vertical beam body 100 and the hollow portion 110; that is, the connecting structure 120 and the hollow portion 110 are formed at both ends of the vertical beam body 100 along its length. As a specific embodiment, such as... Figure 3 As shown, the hollow part 110 is located at the bottom end of the vertical beam body 100, and the connecting structure 120 is located at the top end of the vertical beam body 100.

[0103] In this embodiment, the range of the central angle corresponding to the arc-shaped connecting structure 120 is not limited and can be selected as needed. As a specific embodiment, for example... Figure 14 , Figure 15 and Figure 16 As shown, the central angle of the arc-shaped connecting structure 120 is 90°.

[0104] The first fixing seat 600 is used to fix the vertical beam body 100 and to prevent cold air from leaking out of the refrigerator 1. Since both the first guide groove 610 and the connecting structure 120 are arc-shaped, such as... Figure 14 , Figure 15 and Figure 16 As shown, the gap between the first guide groove 610 and the connecting structure 120 is small and relatively uniform, which further prevents cold air from leaking out of the refrigerator 1.

[0105] In some other embodiments, the inner wall of the first guide groove 610 includes an inlet section 611 and a tangential section 612, which are sequentially connected along the inlet direction of the connecting structure 120 into the first guide groove 610. That is, as shown... Figure 11 , Figure 14 , Figure 15 and Figure 16 As shown, the inlet segment 611 and the tangential segment 612 are connected sequentially. The curvature of the inlet segment 611 is less than the curvature of the tangential segment 612, that is, as... Figure 11 , Figure 14 , Figure 15 and Figure 16 As shown, the tangential section 612 is more curved than the inlet section 611. This facilitates the insertion of the connecting structure 120 into the first fixing seat 600 and further reduces the gap between the first guide groove 610 and the connecting structure 120, preventing cold air from leaking out of the refrigerator 1.

[0106] In some other embodiments, the central angle corresponding to the introductory segment 611 ranges from 10° to 20°. As a specific embodiment, such as... Figure 14 , Figure 15 and Figure 16 As shown, the central angle corresponding to the guide segment 611 is 15°. The central angle corresponding to the concave part of the contact portion is 15° larger than the central angle corresponding to the connecting portion. These two angles are the same size, which makes it easier for the connecting structure 120 to be introduced into the first fixing seat 600 in the initial stage. That is, in this stage, the telescopic structure 200 is still located inside the hollow part 110, and the curvature of the guide segment 611 is less than the curvature of the tangential segment 612. Therefore, the connecting structure 120 is easily introduced into the first fixing seat 600.

[0107] In some other embodiments, the first fixing base 600 further includes a guide block 620 disposed within the first guide groove 610. An elongated guide groove 121 is formed at the end of the connecting structure 120; the guide groove 121 has an opening facing away from the rotating shaft 300, so that during the opening and closing of the refrigerator door 20, the guide block 620 is guided into or disengaged from the guide groove 121.

[0108] In this embodiment, the specific shape of the guide block 620 can be selected as needed. As a specific embodiment, for example... Figure 14 , Figure 15 and Figure 16 As shown, the guide block 620 is arc-shaped, which facilitates the guide block 620 being guided into the guide groove 121.

[0109] The guide groove 121 has an opening facing away from the rotation shaft 300; that is, the opening 1211 of the guide groove and the rotation shaft 300 are located on opposite sides of the vertical beam body 100. Figure 3 As shown, the rotating shaft 300 is located on the left side of the vertical beam body 100, and the opening 1211 of the guide groove is located on the right side of the vertical beam body 100. Figure 14 , Figure 15 and Figure 16 As shown, the rotating shaft 300 is located on the right side of the vertical beam body 100, and the opening of the guide groove is located on the left side of the vertical beam body 100. Figure 14 , Figure 15 and Figure 16 The process of the connecting structure 120 being inserted into or detached from the first guide groove 610 along the inner wall of the first guide groove 610 is demonstrated, as is the process of the guide block 620 being inserted into or detached from the guide groove 121 along the guide groove 121. Figure 14 , Figure 15 and Figure 16 As shown, the guide block 620 makes it easier for the connecting structure 120 to be inserted into the first fixing seat 600, and prevents the connecting structure 120 from deviating from the trajectory.

[0110] In some other embodiments, such as Figure 14 , Figure 15 and Figure 16 As shown, the guide block 620 is located at the end of the inlet section 611 along the inlet direction. That is, when the vertical beam body 100 rotates 10° to 20°, the guide block 620 just contacts the opening 1211 of the guide groove, which facilitates the smooth introduction of the connecting structure 120 into the first fixed seat 600.

[0111] In some other embodiments, both the guide block 620 and the guide groove 121 are arc-shaped, and as the guide block 620 slides along the guide groove 121, it is in contact with at least one of the inner sidewalls of the guide groove 121. This limits the rotational trajectory of the connecting structure 120 to accurately guide the vertical beam body 100 into the refrigerator 1.

[0112] In some other embodiments, the vertical beam assembly 10 further includes a second fixing seat 700, which is disposed at the opening 30 of the refrigerator. The second fixing seat 700 has a forward-facing, arc-shaped second guide groove 710. The second guide groove 710 is used to guide the hollow portion 110 along the second guide groove 710 into or out of the second guide groove 710 during the opening and closing of the refrigerator door 20. The hollow portion 110 is arc-shaped.

[0113] In this embodiment, the curvature corresponding to the second guide groove 710 is not limited and can be selected as needed. As a specific embodiment, such as... Figure 12 As shown, the arc of the second guide groove 710 is 90°, which allows the hollow part 110 to be completely accommodated within the second guide groove 710.

[0114] In some other embodiments, the telescopic structure 200 is configured to extend when the connecting structure 120 rotates to the end of the guide section 611. This avoids the extended structure increasing the frictional force during the guide of the vertical beam body 100, thereby allowing the connecting structure 120 to smoothly guide into the second fixed seat 700.

[0115] In some other embodiments, the central angles of the connecting structure 120, the first guide groove 610, the second guide groove 710, and the hollow portion 110 range from 80° to 110°. This allows the connecting structure 120 to rotate along the first guide groove 610 within a rotation range of 80° to 110°, and allows the connecting structure 120 to be completely contained within the first guide groove 610. Similarly, this allows the hollow portion 110 to rotate along the second guide groove 710, and allows the hollow portion 110 to be completely contained within the second guide groove 710. This further reduces cold leakage in the refrigerator 1.

[0116] In some other embodiments, the telescopic structure 200 is arc-shaped, the inner wall of the first guide groove 610 is adapted to the outer wall of the connecting structure 120, and the inner wall of the second guide groove 710 is adapted to the outer wall of the telescopic structure 200.

[0117] The inner wall of the first guide groove 610 is adapted to the outer wall of the connecting structure 120. That is, the spacing between the inner wall of the first guide groove 610 and the outer wall of the connecting structure 120 is uniform, and the gap between the inner wall of the first guide groove 610 and the outer wall of the connecting structure 120 is small.

[0118] The inner wall of the second guide groove 710 is adapted to the outer wall of the telescopic structure 200. That is, the distance between the inner wall of the second guide groove 710 and the outer wall of the hollow part 110 is uniform, and the gap between the inner wall of the second guide groove 710 and the outer wall of the hollow part 110 is small. This can prevent the refrigerator 1 from leaking cold, and make the refrigerator 1 have a better air resistance effect.

[0119] According to a second aspect of the present invention, a refrigerator 1 is also provided, the refrigerator 1 including a vertical beam assembly 10 for the refrigerator 1 door 20 as described above. Since the refrigerator 1 includes any of the vertical beam assemblies 10 described above, the refrigerator 1 possesses the technical effects of any of the vertical beam assemblies 10 described above, which will not be described in detail here.
