As shown in fig. 1 to 9, the present embodiment provides a vertical beam assembly 10 for a door body 20 of a refrigerator 1, the vertical beam assembly 10 including a vertical beam main body 100, a telescopic structure 200, a rotation shaft 300, and a coupling assembly 400. The vertical beam body 100 has a hollow portion 110 formed at an end in a longitudinal direction thereof. The telescopic structure 200 moves in the length direction of the vertical beam body 100 to extend from the hollow portion 110 or retract into the hollow portion 110.

The rotation shaft 300 is rotatably provided in the vertical beam body 100, and the rotation shaft 300 is configured to rotatably provide the vertical beam body 100 to the door body 20 of the refrigerator 1, and an outer circumferential wall of the rotation shaft 300 has at least one stopper pin 330.

The linkage assembly 400 is disposed in the vertical beam body 100, and the linkage assembly 400 is configured to be movable along a length direction of the vertical beam body 100 so as to extend or retract the telescopic structure 200 from the hollow portion 110. The linkage assembly 400 has a bearing portion 414. The bearing portion 414 is arc-shaped, 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 configured to have at least one stopper pin 330 disposed therein in a one-to-one correspondence, and is configured to move the interlock assembly 400 along the longitudinal direction of the vertical beam body 100 when the rotation shaft 300 rotates.

In the present embodiment, the number of the door bodies 20 of the refrigerator 1 is not limited, and may be selected as needed. As a specific example, as shown in fig. 1 and 2, the refrigerator 1 is a three-door refrigerator 1.

In the present embodiment, the door body 20 of the refrigerator 1 rotatably coupled to the vertical beam assembly 10 is not limited and may be selected as desired. As a specific example, as shown in fig. 2 and 3, the vertical beam body 100 is connected to the left door body 20 of the refrigerator 1. It will be apparent that this is by way of example only and not by way of example only. In fig. 2, in order to fully illustrate the connection between the left door 20 and the vertical beam body 100 of the refrigerator 1, the right door 20 of the refrigerator 1 is not shown in fig. 2.

During the opening of the left door 20, the vertical beam body 100 is rotated out of the refrigerator 1 following the left door 20. During the closing of the left door 20, the vertical beam body 100 is screwed into the refrigerator 1 following the left door 20. In the case where the door body 20 of the refrigerator 1 is closed, as shown in fig. 1 and 2, the vertical beam body 100 is located between the left and right door bodies 20 and 20 to prevent cool air from leaking out from between the left and right door bodies 20 and 20.

In this embodiment, the end of the vertical beam body 100 in the length direction thereof may be an upper end of the vertical beam body 100 and/or a lower end of the vertical beam body 100. As a specific example, as shown in fig. 3 to 6, the end of the girder body 100 in the length direction thereof refers to the lower end of the girder body 100, and it is apparent that this is only exemplary and not exclusive.

In the present embodiment, the outer shape of the hollow portion 110 and the inner shape of the hollow portion 110 are not limited, and may be selected as needed. As a specific example, as shown in fig. 13, the outer shape of the hollow portion 110 and the inner shape of the hollow portion 110 are both arc-shaped, which facilitates screwing the vertical beam body 100 into the refrigerator 1 or unscrewing from the refrigerator 1. It will be apparent that this is by way of example only and not by way of example only.

In the present embodiment, the specific shape of the telescopic structure 200 is not limited, and may be selected as needed. As shown in fig. 10, as a specific embodiment, the specific shape of the telescopic structure 200 is an arc shape, and the outer peripheral wall of the telescopic structure 200 is fitted 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 in fig. 6, the telescopic structure 200 moves up and down along the inner wall of the hollow 110. The telescopic structure 200 with the shape has better choke effect.

In the present embodiment, the rotation shaft 300 is rotatably provided in the vertical beam body 100. During the opening of the door 20 of the refrigerator 1, the vertical beam body 100 is rotated about the rotation shaft 300 to be unscrewed from the refrigerator 1. During the closing of the door 20 of the refrigerator 1, the vertical beam body 100 is rotated about the rotation shaft 300 to be screwed into the refrigerator 1. In the present embodiment, the angle through which the vertical beam body 100 is rotated during the opening or closing of the door body 20 of the refrigerator 1 is not limited, and may be selected as desired.

As a specific example, the rotation shaft 300 is rotatably provided at one side of the girder body 100. As shown in fig. 2 to 3, the left side of the vertical beam body 100 is rotatably provided on the left door body 20 of the refrigerator 1, and a rotation shaft 300 is rotatably provided in the left side of the vertical beam body 100. It will be apparent that this is by way of example only and not by way of example only.

As a specific example, as shown in fig. 9, the outer circumferential wall of the rotation shaft 300 has at least one stopper pin 330, and the outer circumferential wall of the rotation shaft 300 has two stopper pins 330. It should be apparent that this is by way of example only and not by way of limitation, and that the number of stop pins 330 may be one, three, four or more. In this embodiment, the limiting pin 330 and the rotation shaft 300 may be integrally formed or be a split structure. The shape of the stopper pin 330 is not particularly limited and may be selected as needed.

The interlock assembly 400 is disposed in the vertical beam body 100, and the interlock assembly 400 is configured to be movable only in the longitudinal direction of the vertical beam body 100. That is, the interlock assembly 400 can move only in the longitudinal direction of the vertical beam body 100, i.e., the interlock assembly 400 can move only up and down.

In this embodiment, the specific components included in the linking component 400 are not limited, and may be selected according to requirements. As a specific embodiment, as shown in fig. 7, the linkage assembly 400 includes a linkage shaft 410 and a linkage structure 430. In the present embodiment, the specific manner of the linkage assembly 400 for extending or retracting the telescopic structure 200 from or into the hollow portion 110 is not limited. For example, the linkage assembly 400 may directly drive the telescopic structure 200 to move up and down, or the linkage assembly 400 indirectly drives the telescopic structure 200 to move up and down.

In this embodiment, the linkage assembly 400 has a bearing portion 414, and the bearing portion 414 is arc-shaped. In the present embodiment, the specific shape of the bearing portion 414 is not limited, and for example, the bearing portion 414 may include a circular arc, may include a semi-cylinder shape, or include a cylinder. As a specific example, as shown in fig. 7 and 8, the carrier 414 comprises a cylinder, it being apparent that this is by way of example only and not by way of limitation.

In the present embodiment, the interval between the inner peripheral wall of the bearing portion 414 and the outer peripheral wall of the rotation shaft 300 is not limited, and may be selected as needed. As shown in fig. 6, the interval between the inner peripheral wall of the bearing portion 414 and the outer peripheral wall of the rotation shaft 300 is small and negligible.

In the present embodiment, the specific number of the guide portions 415 is not limited, and may be selected as needed. As a specific example, as shown in fig. 6 to 8, the number of the guide portions 415 is two. It will be apparent that this is by way of example only and not by way of limitation, and that the number of guides 415 may be one, three, four or more, for example.

In this embodiment, the guide portion 415 and the carrying portion 414 may be integrally formed or be a split structure. For example, the guide portion 415 may be a blind groove or a through groove formed on the carrying portion 414.

In the present embodiment, the specific shape of the guide portion 415 is not limited, and as shown in fig. 7 to 8, the guide portion 415 may extend along the circumferential direction and the axial direction of the bearing portion 414. As shown in fig. 8, each guide portion 415 includes a first segment 4151, a middle segment 4152 and a second segment 4153 connected in sequence along the extending direction thereof, the first segment 4151 and the second segment 4153 are horizontal segments, and the middle segment 4152 is disposed obliquely, wherein the first segment 4151 is close to the telescopic structure 200. It will be apparent that this is by way of example only and not by way of example only.

During the rotation of the rotation shaft 300, since the interlocking assembly 400 cannot rotate, the interlocking assembly 400 moves in the longitudinal direction of the vertical beam body 100 with the cooperation of the stopper pin 330 and the guide portion 415.

Specifically, the stopper pin 330 moves from the first section 4151 to the second section 4153 during the closing of the door 20 of the refrigerator 1. The linkage assembly 400 moves toward the telescopic structure 200, i.e., downward. The telescopic structure 200 moves downward to protrude from the inside of the hollow portion 110 to achieve a choke effect.

During the opening of the door 20 of the refrigerator 1, the stopper 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 upward, and the telescopic structure 200 is retracted into the hollow portion 110. This can reduce the friction of the telescopic structure 200 so that the vertical beam body 100 is unscrewed from the refrigerator 1.

The vertical beam assembly 10 provided in this embodiment is closed along with the door body 20 of the refrigerator 1, and the telescopic structure 200 therein naturally extends to achieve the wind assembly effect. The vertical beam assembly 10 is naturally retracted with the opening of the door 20 of the refrigerator 1, and the telescopic structure 200 therein is opened to facilitate the opening of the door 20.

In this embodiment, the angle through which the vertical beam main body 100 rotates in the process of opening the door body 20 of the refrigerator 1 to closing or in the process of closing the door body 20 of the refrigerator 1 to opening is not limited, and may be selected according to requirements. As a specific example, as shown in fig. 7 and 8, the vertical beam body 100 is rotated 90 ° counterclockwise during the closing to opening of the door body 20 of the refrigerator 1. The vertical beam body 100 is rotated by 90 ° clockwise during the process of opening to closing the door body 20 of the refrigerator 1.

In the vertical beam assembly 10 provided in this embodiment, the rotation shaft 300 is matched with the pin slot of the linkage assembly 400, and in the process of closing the door body 20, the rotation of the rotation shaft 300 can trigger the linkage assembly 400 to move along the length direction of the vertical beam main body 100, and the linkage assembly 400 enables the telescopic structure 200 to extend from the hollow portion 110 or retract into the hollow portion 110. This allows the vertical beam assembly 10 to naturally extend out of the telescopic structure 200 as the door 20 of the refrigerator 1 is closed to achieve a wind-up effect. The vertical beam assembly 10 is naturally retracted with the opening of the door 20 of the refrigerator 1, and the telescopic structure 200 therein is opened to facilitate the opening of the door 20.

In other embodiments, each guide 415 is a groove formed in the peripheral wall of the carrier 414. This allows for a simple construction of the mullion assembly 10.

In other embodiments, the central angle corresponding to each guide 415 ranges from 80 ° to 100 °. That is, the vertical beam body 100 is rotated through an angle ranging from 80 ° to 110 ° in the process of completing the opening or closing of the door body 20 of the refrigerator 1. That is, during the opening and closing of the door body 20 of the refrigerator 1, the vertical beam body 100 rotates 80 ° to 110 ° with the door body 20 to be rotated out of the refrigerator 1 or screwed into the refrigerator 1. That is, the stopper pin 330 is moved from the second section 4153 to the first section 4151 or from the first section 4151 to the second section 4153, and the vertical beam body 100 is rotated through an angle ranging from 80 ° to 110 °, during which the door body 20 of the refrigerator 1 is completely switched to be opened and closed.

As shown in fig. 1 and 2, if the rotation angle of the vertical beam body 100 is too small, the vertical beam body 100 is 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 needs to be opened after the right door body 20 is opened. If the rotation angle of the vertical beam body 100 is too large, the vertical beam body 100 is not easily introduced into the refrigerator 1 when the door body 20 of the refrigerator 1 is changed from the opened state to the closed state. As a specific example, as shown in fig. 14 to 16, the refrigerator 1 door 20 is rotated by 90 ° during opening and closing of the vertical beam body 100.

In other embodiments, each guide 415 includes a first segment 4151, a middle segment 4152, and a second segment 4153 that are sequentially connected along the extending direction thereof, the first segment 4151 is adjacent to the telescopic structure 200, the first segment 4151 is a horizontal segment, and the middle segment 4152 is disposed obliquely.

During the closing of the door 20 of the refrigerator 1, the stopper pin 330 moves from the first section 4151 to the second section 4153. The first section 4151 is a horizontal section, that is, the position of the linkage assembly 400 and the telescopic structure 200 is not changed during the movement of the first section 4151 by the limiting pin 330. That is, the interlock assembly 400 does not move along the length direction of the girder body 100 during this process. That is, the telescopic structure 200 does not protrude from the hollow portion 110 during the previous rotation of the vertical beam body 100 during the closing of the door body 20 of the refrigerator 1. This reduces friction between the telescopic structure 200 and the refrigerator 1, facilitating the rotation of the vertical beam body 100 into the refrigerator 1.

During the opening of the door 20 of the refrigerator 1, the stopper pin 330 moves from the second section 4153 to the first section 4151. In the case where the door body 20 of the refrigerator 1 is opened, the vertical beam body 100 loses restriction, that is, the vertical beam body 100 may be rotated by a false 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 vertical beam main body 100 from being rotated randomly, so as to ensure smooth closing of the door body 20 of the refrigerator 1.

In other embodiments, the first segment 4151 is proximate the telescoping structure 200, and the first segment 4151 corresponds to a central angle in the range of 10 ° to 20 °. The limiting pin 330 is always positioned at the first section 4151 during the process of closing the door body 20 of the refrigerator 1 and the process of rotating the rotating shaft 300 by 10 ° to 20 °. That is, the interlock assembly 400 does not move along the length direction of the girder body 100 during this process. That is, during the closing of the door body 20 of the refrigerator 1, the telescopic structure 200 does not protrude from the inside of the hollow portion 110 for the first 10 ° to 20 ° of the rotation of the vertical beam body 100. This reduces friction between the telescopic structure 200 and the refrigerator 1, facilitating the rotation of the vertical beam body 100 into the refrigerator 1.

In other embodiments, as shown in fig. 6 to 7, the bearing portion 414 is cylindrical and is sleeved on the rotating shaft 300. The at least one guide portion 415 includes a first guide portion 415 and a second guide portion 415 disposed opposite to each other. The at least one stopper pin 330 includes a first stopper pin 330 and a second stopper pin 330 disposed along a radial direction of the rotation shaft 300, the first stopper pin 330 and the second stopper pin 330 being disposed in the first guide portion 415 and the second guide portion 415, respectively. This allows the force applied by the linkage assembly 400 and the telescoping structure 200 to be relatively balanced.

In other embodiments, the linkage assembly 400 further includes a linkage shaft 410 and a first spring 420. The coupling shaft 410 is disposed in the vertical beam body 100, has a bearing portion 414, and extends from the rotation shaft 300 through an end portion of the vertical beam body 100 into the hollow portion 110. The first spring 420 is sleeved on the coupling shaft 410, and two ends of the first spring are respectively connected with the end portion of the vertical beam main body 100 and the bearing portion 414, and configured to be compressed when the telescopic structure 200 extends out from the hollow portion 110.

In this embodiment, the linkage assembly 400 includes a linkage shaft 410, and the linkage shaft 410 is used to sleeve the first spring 420 thereon. The linkage shaft 410 is used for avoiding the problems of uneven stress or inclination of the first spring 420. In the present embodiment, the type of the coupling shaft 410 is not limited, and for example, the coupling shaft 410 may be a circular shaft or a non-circular shaft.

The first spring 420 is configured to be compressed when the telescopic structure 200 is extended from the hollow 110, that is, the first spring 420 is compressed to start the power storage when the coupling shaft 410 moves downward. When the telescopic structure 200 is retracted into the hollow portion 110, that is, when the coupling shaft 410 moves upward, the coupling shaft 410 moves toward the rotation shaft 300, the compressed first spring 420 provides upward power to the coupling shaft 410 to move the coupling shaft 410 upward.

In other embodiments, the mullion 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 disposed in the telescopic structure 200 for connecting the end of the vertical beam body 100 and the telescopic structure 200, and configured to be compressed when the telescopic structure 200 is retracted into the hollow 110.

The plurality of second springs 500 are configured to be compressed when the telescopic structure 200 is retracted into the hollow 110. When the telescopic structure 200 is extended out of the hollow 110, the compressed plurality of second springs 500 provide power to the telescopic structure 200 to extend the telescopic structure 200 out of the hollow 110. The plurality of second springs 500 are uniformly arranged so that the telescopic structure 200 is uniformly stressed, so that the telescopic structure 200 can be smoothly extended or retracted into the hollow portion 110 a plurality of times.

In 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 mullion body 100 to prevent the bearing portion 414 from rotating.

In the present embodiment, the shape of the limiting portion 412 is not limited, and the limiting portion 412 can prevent the abutting portion from rotating, and the limiting portion 412 can move along the length direction of the vertical beam main body 100. As a specific example, as shown in fig. 8, the shape of the limiting portion 412 is an elongated shape, and it is obvious that this is only exemplary and not exclusive.

In the present embodiment, the number of the limiting portions 412 is not limited, and may be selected as needed. As a specific example, as shown in fig. 8, the number of the limiting portions 412 is 4, and is uniformly distributed along the outer peripheral wall of the interference portion.

In other embodiments, the linkage assembly 400 extends from the rotational shaft 300 to the middle of the telescopic structure 200 to extend or retract the telescopic structure 200 from or into the hollow 110. In the present embodiment, the specific manner of extending the linkage assembly 400 to the middle of the telescopic structure 200 is not limited, and may be selected according to the need. The linkage assembly 400 extends to the middle of the telescopic structure 200, so that the telescopic structure 200 is uniformly stressed.

In other embodiments, the linkage assembly 400 includes a linkage structure 430, and the linkage structure 430 follows the movement of the linkage assembly 400 along the length direction of the vertical beam body 100. The linkage structure 430 is disposed in the hollow portion 110, and has a force application section 431. The telescopic structure 200 has a receiving portion 210 protruding toward an end of the girder body 100, and a force applying section 431 is received in the receiving portion 210 to extend or retract the telescopic structure 200 from the hollow portion 110.

In the present embodiment, the specific shapes of the linkage structure 430 and the force application section 431 are not limited, and may be selected according to requirements. As shown in fig. 7, the linking structure 430 is L-shaped and the force applying section 431 is elongated. It will be apparent that this is by way of example only and not by way of example only.

As shown in fig. 10, the telescopic structure 200 has a receiving portion 210 protruding toward the end of the vertical beam body 100, that is, the telescopic structure 200 has an upwardly protruding receiving portion 210. The force applying section 431 is disposed in the accommodating portion 210 to extend or retract the telescopic structure 200 from the hollow portion 110, and the connection is simple and easy to detach and replace.

In other embodiments, the shape of the accommodating portion 210 and the force application section 431 is elongated, and the accommodating portion 210 and the force application section 431 are disposed along the transverse direction of the vertical beam main body 100. That is, the receiving portion 210 and the force application section 431 extend from one side of the vertical beam body 100 to the other side of the vertical beam body 100. That is, the receiving portion 210 and the urging section 431 extend from the left side of the vertical beam body 100 to the right side of the vertical beam body 100. This makes the telescopic structure 200 uniformly stressed.

In other embodiments, the force applying section 431 is configured to abut against the accommodating portion 210 to move the telescopic structure 200 when the telescopic structure 200 is retracted into the hollow portion 110. That is, as shown in fig. 7, the force applying section 431 abuts against the upper side of the accommodating portion 210 and drives the telescopic structure 200 to move upwards. That is, the force applying section 431 is the motive force for the upward movement of the telescopic structure 200.

In other embodiments, the force applying section 431 is configured to disengage the interference receiving portion 210 when the telescoping structure 200 extends from within the hollow portion 110. The urging section 431 moves downward to disengage from the upper side of the interference receiving portion 210, and the telescopic structure 200 moves downward to protrude from the hollow portion 110 under the urging force of the second spring 500. That is, as shown in fig. 10, the distance between the upper side of the accommodating part 210 to the lower side of the accommodating part 210 defines the range in which the linkage assembly 400 and the telescopic structure 200 move up and down. The manner in which the linkage assembly 400 controls the movement of the telescopic structure 200 makes the telescopic structure 200 uniformly stressed.

In other embodiments, the linkage structure 430 further has a conductive section 432, and two ends of the conductive section 432 are connected to the force applying section 431 and the linkage shaft 410, respectively. In the present embodiment, the shape of the conductive segment 432 is not limited, and may be selected as needed. As a specific example, as shown in fig. 7, the conductive segments 432 are plate-shaped, and it is apparent that this is by way of example only and not by way of limitation.

In other embodiments, the connecting shaft 410 extends out of two symmetrical clamping portions 413, and the conductive segment 432 is clamped between the two clamping portions 413. In the present embodiment, the specific shape of the engaging portion 413 is not limited, and may be selected as needed. As shown in fig. 8, the clamping portion 413 is a claw extending from the connecting shaft 410, and the conductive segment 432 is clamped between the two claws. And the middle portion of the conductive segment 432 is fixed to the coupling shaft 410 by a screw, which further prevents the coupling shaft 410 from rotating.

In other embodiments, the ends of the vertical beam body 100 along its length form an arcuate connecting structure 120. The vertical beam assembly 10 further includes a first fixing base 600, and the first fixing base 600 is disposed at the opening 30 of the refrigerator. The first fixing base 600 has a first guide groove 610 having an arc shape and opening forward. The first fixing base 600 is used for guiding the connection structure 120 into the first guide groove 610 along the inner sidewall of the first guide groove 610 or separating from the first guide groove 610 during the opening and closing of the door 20 of the refrigerator 1.

In the present embodiment, the opposite ends of the vertical beam body 100 and the hollow portion 110 form an arc-shaped connection structure 120, that is, the two ends of the vertical beam body 100 along the length direction thereof form the connection structure 120 and the hollow portion 110, respectively. As a specific example, as shown in fig. 3, the hollow portion 110 is located at the bottom end of the girder body 100, and the connection structure 120 is located at the top end of the girder body 100.

In the present embodiment, the range of the central angle corresponding to the circular arc-shaped connection structure 120 is not limited, and may be selected according to the need. As a specific example, as shown in fig. 14, 15 and 16, the circular arc-shaped connection structure 120 corresponds to a central angle of 90 °.

The first fixing base 600 is used to fix the vertical beam body 100, and the first fixing base 600 is used to prevent cool air from leaking out of the refrigerator 1. Since both the first guide groove 610 and the connection structure 120 are arc-shaped, as shown in fig. 14, 15 and 16, a gap between the first guide groove 610 and the connection structure 120 is small and relatively uniform, which further prevents the cool air from leaking out of the refrigerator 1.

In other embodiments, the inner sidewall of the first guide groove 610 includes a lead-in section 611 and a tangential section 612, and the lead-in section 611 and the tangential section 612 are sequentially connected along the lead-in direction of the connection structure 120 into the first guide groove 610. That is, as shown in fig. 11, 14, 15 and 16, the lead-in section 611 and the tangential section 612 are connected in order. The curvature of the lead-in section 611 is smaller than the curvature of the tangential section 612, i.e., the tangential section 612 is curved to a greater extent than the lead-in section 611, as shown in fig. 11, 14, 15 and 16. This facilitates the introduction of the connection structure 120 into the first fixing base 600, and also further reduces the gap between the first guide groove 610 and the connection structure 120, preventing the cool air from leaking out of the refrigerator 1.

In other embodiments, the lead-in segment 611 corresponds to a central angle in the range of 10 ° to 20 °. As a specific example, as shown in fig. 14, 15 and 16, the angle of the central angle corresponding to the lead-in section 611 is 15 °. The central angle corresponding to the concave position of the abutting part is 15 degrees more than the central angle corresponding to the connecting part. The two angles are the same, which makes it easier to introduce the connecting structure 120 into the first fixing base 600 at the initial stage. That is, the telescopic structure 200 is also located in the hollow 110 at this stage, and the curvature of the introduction section 611 is smaller than that of the tangential section 612, so that the connection structure 120 is easily introduced into the first fixing base 600.

In other embodiments, the first fixing base 600 further includes a guide block 620, and the guide block 620 is disposed in the first guide groove 610. An end of the connecting structure 120 is provided with a strip-shaped guide groove 121; the guide groove 121 has an opening facing away from the rotation shaft 300 so that the guide block 620 is introduced into the guide groove 121 or is separated from the guide groove 121 during the opening and closing of the door 20 of the refrigerator 1.

In this embodiment, the specific shape of the guide block 620 may be selected according to need, and as a specific embodiment, as shown in fig. 14, 15 and 16, the guide block 620 has a circular arc shape, which facilitates the guide block 620 to be guided into the guide groove 121.

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 at both sides of the girder body 100, respectively. As shown in fig. 3, the rotation shaft 300 is located at the left side of the vertical beam body 100, and the opening 1211 of the guide groove is located at the right side of the vertical beam body 100. As shown in fig. 14, 15 and 16, the rotation shaft 300 is located at the right side of the vertical beam body 100, and the opening of the guide groove is located at the left side of the vertical beam body 100. Fig. 14, 15 and 16 illustrate a process in which the connection structure 120 is introduced into the first guide groove 610 along the inner sidewall of the first guide groove 610 or is separated from the first guide groove 610, and also illustrate a process in which the guide block 620 is introduced into the guide groove 121 or is separated from the guide groove 121. As shown in fig. 14, 15 and 16, the guide block 620 makes it easier to guide the connection structure 120 into the first fixing base 600, so as to avoid the connection structure 120 from deviating from the track.

In other embodiments, as shown in fig. 14, 15 and 16, the guide block 620 is located at the end of the lead-in section 611 in the lead-in 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 smooth introduction of the connection structure 120 into the first fixing base 600.

In other embodiments, the guide block 620 and the guide groove 121 are each arc-shaped, and the guide block 620 is attached to at least one inner sidewall of the guide groove 121 during the sliding of the guide block 620 along the guide groove 121. This can define the rotation locus of the connection structure 120 to accurately guide the vertical beam body 100 into the inside of the refrigerator 1.

In other embodiments, the vertical beam assembly 10 further includes a second fixing base 700, where the second fixing base 700 is disposed at the opening 30 of the refrigerator, and the second fixing base 700 has a second guide groove 710 with a circular arc shape and opening forward. The second guide groove 710 is used to guide the hollow portion 110 into the second guide groove 710 along the second guide groove 710 or to separate from the second guide groove 710 during the opening and closing of the door 20 of the refrigerator 1. The hollow portion 110 has an arc shape.

In this embodiment, the radian corresponding to the second guide groove 710 is not limited, and may be selected according to needs. As a specific example, as shown in fig. 12, the second guide groove 710 has an arc of 90 °, which allows the hollow portion 110 to be completely accommodated in the second guide groove 710.

In other embodiments, the telescoping structure 200 is configured to extend when the connecting structure 120 is rotated to the end of the lead-in section 611, which avoids the extending structure increasing the friction of the lead-in of the mullion body 100, thereby allowing the connecting structure 120 to be smoothly led into the second fixing base 700,

in other embodiments, the central angles of the connection structure 120, the first guide groove 610, the second guide groove 710, and the hollow portion 110 may range from 80 ° to 110 °. This allows the vertical beam body 100 to rotate along the first guide groove 610 in the range of 80 to 110, and allows the connection structure 120 to be completely accommodated in the first guide groove 610. Again, this allows the hollow portion 110 to rotate along the second guide groove 710 and allows the hollow portion 110 to be completely accommodated in the second guide groove 710. This can further reduce the cold leakage of the refrigerator 1.

In other embodiments, the telescopic structure 200 is arc-shaped, the inner side wall of the first guiding groove 610 is adapted to the outer side wall of the connecting structure 120, and the inner side wall of the second guiding groove 710 is adapted to the outer side wall of the telescopic structure 200.

The inner sidewall of the first guide groove 610 is matched with the outer sidewall of the connection structure 120, that is, the inner sidewall of the first guide groove 610 is uniformly spaced from the outer sidewall of the connection structure 120, and the gap between the inner sidewall of the first guide groove 610 and the outer sidewall of the connection structure 120 is smaller.

The inner side wall of the second guide groove 710 is matched with the outer side wall of the telescopic structure 200, that is, the inner side wall of the second guide groove 710 and the outer side wall of the hollow portion 110 are uniformly spaced, and the gap between the inner side wall of the second guide groove 710 and the outer side wall of the hollow portion 110 is smaller. This can avoid the refrigerator 1 from leaking cold, so that the choke effect of the refrigerator 1 is good.
