[0058] As Figures 1 to 8As shown, the present embodiment provides a vertical beam assembly 10 for a refrigerator 1 door body 20, which comprises a vertical beam body 100, a telescopic structure 200, a rotating shaft 300 and a linkage assembly 400. The vertical beam body 100 is formed with a hollow portion 110 at an end thereof along a length direction of the vertical beam body 100. The telescopic structure 200 is movable along 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.

[0059] The rotating shaft 300 is rotatably arranged in the vertical beam body 100, and the rotating shaft 300 is configured to rotatably arrange the vertical beam body 100 on the refrigerator 1 door body 20, and has at least one protrusion at an end thereof close to the telescopic structure 200.

[0060] The linkage assembly 400 is arranged in the vertical beam body 100, and is configured to, in the case that the rotating shaft 300 rotates, abut different positions of the end of the rotating shaft 300 to move 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.

[0061] In the present embodiment, the number of the refrigerator 1 door bodies 20 is not limited, and can be selected as needed. As a specific embodiment, as shown in Figure 1 and Figure 2 , the refrigerator 1 is a three-door refrigerator 1.

[0062] In the present embodiment, the refrigerator 1 door body 20 rotatably connected with the vertical beam assembly 10 is not limited, and can be selected as needed. As a specific embodiment, as shown in Figure 2 and Figure 3 , the vertical beam body 100 is connected with a 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 .

[0063] 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 refrigerator 1 door body 20 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.

[0064] In the present embodiment, the end of the vertical beam body 100 along the length direction thereof can be an upper end of the vertical beam body 100 and / or a lower end of the vertical beam body 100. As a specific embodiment, as shown in Figure 3 ,Figure 5 and Figure 6 As shown in FIG. 1, the end of the vertical beam body 100 along the length direction thereof refers to the lower end of the vertical beam body 100, which is merely exemplary and not the only one.

[0065] 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 can be selected as needed. As a specific embodiment, as shown in FIG. 2, 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 merely exemplary and not the only one. Figures 5 to 8

[0066] In the present embodiment, the specific shape of the telescopic structure 200 is not limited and can be selected as needed. As a specific embodiment, as shown in FIG. 3, the specific shape of the telescopic structure 200 is arc-shaped, and the outer peripheral wall of the telescopic structure 200 is attached to the inner wall of the hollow portion 110 and moves up and down along the inner wall of the hollow portion 110. The telescopic structure 200 with such a shape has a better wind-blocking effect. Figures 5 to 8

[0067] In the present embodiment, the rotation shaft 300 is rotatably arranged in the vertical beam body 100. In the process of opening the door body 20 of the refrigerator 1, the vertical beam body 100 rotates around the rotation shaft 300 to rotate out of the refrigerator 1. In the process of closing the door body 20 of the refrigerator 1, the vertical beam body 100 rotates around the rotation shaft 300 to rotate into the refrigerator 1. In the present embodiment, the angle through which the vertical beam body 100 rotates in the process of opening or closing the door body 20 of the refrigerator 1 is not limited and can be selected as needed.

[0068] As a specific embodiment, the rotation shaft 300 is rotatably arranged at one side of the vertical beam body 100. As shown in FIG. 4, the left side of the vertical beam body 100 is rotatably arranged on the left door body 20 of the refrigerator 1, and the rotation shaft 300 is rotatably arranged in the left side of the vertical beam body 100. It is obvious that this is merely exemplary and not the only one. Figures 2 to 3 The end of the rotation shaft 300 close to the telescopic structure 200 has at least one protrusion. That is, as a specific embodiment, as shown in FIG. 5, the bottom end of the rotation shaft 300 has at least one protrusion. In the present embodiment, the shape, size, and number of the protrusion are not limited and can be selected as needed.

[0069] Figures 5 to 8

[0070] ​​​​The linkage assembly 400 is arranged in the vertical beam body 100, and is configured to be able to move only along the length direction of the vertical beam body 100. That is, the linkage assembly 400 can only move along the longitudinal direction of the vertical beam body 100, that is, the linkage assembly 400 can only move up and down.

[0071] In the process of rotating the rotating shaft 300, the linkage assembly 400 abuts against different positions of the end of the rotating shaft 300 to move along the length direction of the vertical beam body 100. That is, when the linkage assembly 400 abuts against the protrusion, the protrusion extrudes the linkage assembly 400 to make the linkage assembly 400 move downward along the length direction of the vertical beam body 100. Otherwise, the linkage assembly 400 moves upward along the length direction of the vertical beam body 100.

[0072] In the present embodiment, the specific structure of the linkage assembly 400 abutting against the end of the rotating shaft 300 is not limited, and can be selected as needed. For example, the linkage assembly 400 has an abutting portion 411 adapted to the end of the rotating shaft 300. As shown in Figures 5 to 7 When the door body 20 of the refrigerator 1 is in the closed state, at least one protrusion abuts against the convex portion 4111 of the abutting portion 411, at which time the linkage assembly 400 and the telescopic structure 200 move downward to extend out of the hollow portion 110 to achieve the wind blocking effect.

[0073] As shown in Figure 8 When the door body 20 of the refrigerator 1 is in the open state, at least one protrusion abuts against the concave portion 4112 of the abutting portion 411 to make the linkage assembly 400 and the telescopic structure 200 move upward, and the telescopic structure 200 retracts into the hollow portion 110. This can reduce the friction of the telescopic structure 200, so that the vertical beam body 100 is rotated out of the refrigerator 1.

[0074] As shown in Figures 2 to 7 When the door body 20 of the refrigerator 1 is in the closed state, the protrusion abuts against the convex portion 4111 of the abutting portion 411, at which time the linkage assembly 400 moves downward, and the telescopic structure 200 also moves downward to achieve the wind blocking effect. As shown in Figure 8 When the door body 20 of the refrigerator 1 is in the open state, the protrusion abuts against the concave portion 4112 of the abutting portion 411, at which time the linkage assembly 400 moves upward, and the telescopic structure 200 also moves upward, and the telescopic structure 200 retracts into the hollow portion 110 to facilitate the vertical beam body 100 to be rotated out of the refrigerator 1 along with the door body 20 of the refrigerator 1. The vertical beam assembly 10 provided in the present embodiment is closed along with the door body 20 of the refrigerator 1, and the telescopic structure 200 therein naturally extends out to achieve the wind blocking effect. The vertical beam assembly 10 is opened along with the door body 20 of the refrigerator 1, and the telescopic structure 200 therein naturally retracts to facilitate the opening of the door body 20.

[0075] In the present embodiment, the angle of rotation of the vertical beam body 100 during the process of opening the door body 20 of the refrigerator 1 to the closed state or during the process of closing the door body 20 of the refrigerator 1 to the open state is not limited and can be selected as desired. As a specific example, as shown in FIG. 2, the vertical beam body 100 is rotated counterclockwise by 90° during the process of closing the door body 20 of the refrigerator 1 to the open state. The vertical beam body 100 is rotated clockwise by 90° during the process of opening the door body 20 of the refrigerator 1 to the closed state. Figure 7 and Figure 8 As shown in FIG. 2, the vertical beam body 100 is rotated counterclockwise by 90° during the process of closing the door body 20 of the refrigerator 1 to the open state. The vertical beam body 100 is rotated clockwise by 90° during the process of opening the door body 20 of the refrigerator 1 to the closed state.

[0076] In the present embodiment, the specific components included in the linkage assembly 400 are not limited and can be selected as desired. As a specific example, as shown in FIG. 3, the linkage assembly 400 includes a linkage shaft 410 and a linkage structure 430. In the present embodiment, the specific manner in which the linkage assembly 400 causes the telescopic structure 200 to extend out of the hollow portion 110 or to retract into the hollow portion 110 is not limited. For example, the linkage assembly 400 can directly move the telescopic structure 200 up and down, or the linkage assembly 400 can indirectly move the telescopic structure 200 up and down. Figure 9 As shown in FIG. 3, the linkage assembly 400 includes a linkage shaft 410 and a linkage structure 430. In the present embodiment, the specific manner in which the linkage assembly 400 causes the telescopic structure 200 to extend out of the hollow portion 110 or to retract into the hollow portion 110 is not limited. For example, the linkage assembly 400 can directly move the telescopic structure 200 up and down, or the linkage assembly 400 can indirectly move the telescopic structure 200 up and down.

[0077] The present embodiment provides that the end of the rotating shaft 300 in the vertical beam assembly 10 has at least one protrusion, and the rotating shaft 300 can touch the linkage assembly 400 to move along the length direction of the vertical beam body 100 during rotation, and the linkage assembly 400 causes the telescopic structure 200 to extend out of the hollow portion 110 or to retract into the hollow portion 110. This causes the vertical beam assembly 10 to naturally extend the telescopic structure 200 out to achieve the group air effect as the door body 20 of the refrigerator 1 is closed. The vertical beam assembly 10 naturally retracts the telescopic structure 200 as the door body 20 of the refrigerator 1 is opened, so as to open the door body 20.

[0078] As shown in FIG. 3, the linkage assembly 400 includes a linkage shaft 410 and a linkage structure 430. In the present embodiment, the specific manner in which the linkage assembly 400 causes the telescopic structure 200 to extend out of the hollow portion 110 or to retract into the hollow portion 110 is not limited. For example, the linkage assembly 400 can directly move the telescopic structure 200 up and down, or the linkage assembly 400 can indirectly move the telescopic structure 200 up and down.

[0079] Figures 2 to 7 As shown in FIG. 3, the linkage assembly 400 includes a linkage shaft 410 and a linkage structure 430. In the present embodiment, the specific manner in which the linkage assembly 400 causes the telescopic structure 200 to extend out of the hollow portion 110 or to retract into the hollow portion 110 is not limited. For example, the linkage assembly 400 can directly move the telescopic structure 200 up and down, or the linkage assembly 400 can indirectly move the telescopic structure 200 up and down.

[0080] As shown in FIG. 3, the linkage assembly 400 includes a linkage shaft 410 and a linkage structure 430. In the present embodiment, the specific manner in which the linkage assembly 400 causes the telescopic structure 200 to extend out of the hollow portion 110 or to retract into the hollow portion 110 is not limited. For example, the linkage assembly 400 can directly move the telescopic structure 200 up and down, or the linkage assembly 400 can indirectly move the telescopic structure 200 up and down. Figure 8 ​As shown, when the door 20 of the refrigerator 1 is in the open state, the protrusion is in contact with the recess 4112 of the contact portion 411, at this time, the linkage assembly 400 moves upward, the telescopic structure 200 also moves upward, the telescopic structure 200 retracts into the hollow portion 110, so as to facilitate the vertical beam body 100 to rotate out of the refrigerator 1 along with the door 20 of the refrigerator 1. The vertical beam assembly 10 provided in the embodiment naturally extends the telescopic structure 200 to achieve the group wind effect when the door 20 of the refrigerator 1 is closed. The vertical beam assembly 10 naturally retracts the telescopic structure 200 when the door 20 of the refrigerator 1 is opened, so as to facilitate the opening of the door 20.

[0081] Meanwhile, the contact portion 411 can prevent the random rotation of the rotating shaft 300, that is, the contact portion 411 limits the rotation of the rotating shaft 300. When the door 20 of the refrigerator 1 is opened, the vertical beam body 100 loses the limitation, that is, the vertical beam body 100 will rotate due to accidental touch, which causes the difficulty in closing the door 20. The contact portion 411 can prevent the random rotation of the vertical beam body 100, so as to ensure the smooth closing of the door 20 of the refrigerator 1.

[0082] In other embodiments, the at least one protrusion includes a first protrusion 310 and a second protrusion 320. The first protrusion 310 is arranged on the end face of the rotating shaft 300. The second protrusion 320 is arranged on the end face of the rotating shaft 300 and is equidistantly arranged along the circumference of the rotating shaft 300 with the first protrusion 310. Since the contact portion 411 is matched with the end of the rotating shaft 300, the contact portion 411 has two protrusions 4111 equidistantly arranged along the circumference thereof. As shown in Figure 5 As shown, the first protrusion 310 and the second protrusion 320 are in contact with the two protrusions 4111 of the contact portion 411 respectively, which makes the force borne by the linkage assembly 400 and the telescopic structure 200 more balanced.

[0083] In other embodiments, the vertical beam body 100 rotates through an angle range of 80° to 110° in the process of completing the opening or closing of the door 20 of the refrigerator 1. That is, in the process of opening and closing the door 20 of the refrigerator 1, the vertical beam body 100 rotates 80° to 110° along with the door 20 to rotate out of the refrigerator 1 or rotate into the refrigerator 1. That is, as shown in Figure 7 、 Figure 8 、 Figure 11 and Figure 12 As shown, in the process of converting the two contact states of the rotating shaft 300 and the linkage assembly 400, the vertical beam body 100 rotates through an angle range of 80° to 110°, and in this process, the door 20 of the refrigerator 1 completes the conversion of opening and closing.

[0084] As shown in Figure 1 and Figure 2As shown, if the vertical beam body 100 rotates at 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 at a too large angle, the vertical beam body 100 is not easy to be introduced into the refrigerator 1 when the door body 20 of the refrigerator 1 is switched from the opened state to the closed state. As a specific example, as shown in FIG. 4, the vertical beam body 100 rotates at an angle of 90° when the door body 20 of the refrigerator 1 is switched from the opened state to the closed state. Figures 1 to 8 As shown, the vertical beam body 100 rotates at an angle of 90° when the door body 20 of the refrigerator 1 is switched from the opened state to the closed state.

[0085] In other embodiments, the linkage assembly 400 includes a linkage shaft 410 and a first spring 420. The linkage shaft 410 has an abutting portion 411 and extends into the hollow portion 110 from the end of the vertical beam body 100 at the rotating shaft 300. The first spring 420 is sleeved on the linkage shaft 410, and the two ends of the first spring 420 are respectively connected to the end of the vertical beam body 100 and the abutting portion 411, and are configured to be compressed when the telescopic structure 200 extends out of the hollow portion 110.

[0086] In the present embodiment, the linkage assembly 400 includes a linkage shaft 410, and the first spring 420 is sleeved on the linkage shaft 410. The linkage shaft 410 is used to avoid uneven force or tilting of the first spring 420. In the present embodiment, the type of the linkage shaft 410 is not limited, for example, the linkage shaft 410 can be a round shaft or a special-shaped shaft.

[0087] As shown in FIG. 5, the first spring 420 is configured to be compressed when the telescopic structure 200 extends out of the hollow portion 110, that is, the first spring 420 is compressed to start storing power when the linkage shaft 410 moves downward. Figure 6 As shown in FIG. 6, when the telescopic structure 200 is retracted into the hollow portion 110, that is, when the linkage shaft 410 moves upward, the compressed first spring 420 provides upward power to the linkage shaft 410 for the upward movement of the linkage shaft 410. Figure 7 Figure 8 As shown in FIG. 6, when the telescopic structure 200 is retracted into the hollow portion 110, that is, when the linkage shaft 410 moves upward, the compressed first spring 420 provides upward power to the linkage shaft 410 for the upward movement of the linkage shaft 410.

[0088] In other embodiments, the vertical beam assembly 10 further includes a plurality of second springs 500. The plurality of second springs 500 are uniformly arranged in the telescopic structure 200, and are configured to be compressed when the telescopic structure 200 is retracted into the hollow portion 110.

[0089] As shown in FIG. 7, the plurality of second springs 500 are configured to be compressed when the telescopic structure 200 is retracted into the hollow portion 110. Figure 8 As shown in FIG. 7, the plurality of second springs 500 are configured to be compressed when the telescopic structure 200 is retracted into the hollow portion 110. Figure 7 ​As shown, when the telescopic structure 200 is extended out of the hollow portion 110, the compressed second springs 500 provide power to the telescopic structure 200 to extend the telescopic structure 200 out of the hollow portion 110. The second springs 500 are evenly arranged so that the telescopic structure 200 is evenly stressed, and the telescopic structure 200 can be smoothly extended or retracted into the hollow portion 110 for multiple times.

[0090] In some other embodiments, the outer peripheral wall of the abutting portion 411 has at least one limiting portion 412, which cooperates with the vertical beam body 100 to avoid rotation of the abutting portion 411.

[0091] In the present embodiment, the shape of the limiting portion 412 is not limited, and the limiting portion 412 can only prevent the abutting portion 411 from rotating, and the limiting portion 412 can move along the length direction of the vertical beam body 100. As a specific embodiment, as shown in Figure 9 the limiting portion 412 has a strip shape. It is obvious that this is only an example, and is not the only one.

[0092] In the present embodiment, the number of the limiting portion 412 is not limited, and can be selected as needed. As a specific embodiment, as shown in Figure 9 the number of the limiting portion 412 is four, and is evenly distributed along the outer peripheral wall of the abutting portion 411.

[0093] In some other embodiments, each protrusion has a first inclined portion 311, a connecting portion 312 and a second inclined portion 313 along the circumferential direction of the rotating shaft 300. The corresponding central angle of the recess 4112 of the abutting portion 411 is 10° to 20° more than the corresponding central angle of the connecting portion 312. The inclination of the second inclined portion 313 is greater than the inclination of the first inclined portion 311.

[0094] In the present embodiment, the shape of the first inclined portion 311, the connecting portion 312 and the second inclined portion 313 is not limited. As a specific embodiment, as shown in Figure 11 and Figure 12 the first inclined portion 311 and the second inclined portion 313 are inclined surfaces, and the connecting portion 312 is a horizontal surface.

[0095] The corresponding central angle of the recess 4112 of the abutting portion 411 is 10° to 20° more than the corresponding central angle of the connecting portion 312. Therefore, as shown in Figure 8 and Figure 11 when the protrusion is located in the recess 4112 of the abutting portion 411, the first inclined portion 311 and the convex portion 4111 of the abutting portion 411 have a flash gap. That is, the rotating shaft 300 is Figure 11 rotated to Figure 12In the process of rotating the rotating shaft 300 by 10-20 degrees, the protrusion is always located in the recess 4112 of the abutting portion 411. That is, in this process, the linkage assembly 400 does not move along the length direction of the vertical beam body 100. That is, in the process of closing the door body 20 of the refrigerator 1, the vertical beam body 100 rotates by 10-20 degrees, and the telescopic structure 200 does not extend out of the hollow portion 110. Alternatively, the corresponding central angle of the recess 4112 of the abutting portion 411 is 65 degrees, the corresponding central angle of the connecting portion 312 is 50 degrees, and the corresponding central angle of the recess 4112 of the abutting portion 411 is 15 degrees larger than the corresponding central angle of the connecting portion 312. This reduces the friction between the telescopic structure 200 and the refrigerator 1, and facilitates the rotation of the vertical beam body 100 into the refrigerator 1.

[0096] The inclination of the second inclined portion 313 is greater than the inclination of the first inclined portion 311. That is, the corresponding central angle of the second inclined portion 313 is smaller than the corresponding central angle of the first inclined portion 311. As shown in Figure 7 、 Figure 8 、 Figure 11 and Figure 12 indicated, this facilitates the rotation of the rotating shaft 300 along the first inclined portion 311 to switch between the two abutting conditions. The greater inclination of the second inclined portion 313 is used to prevent the rotating shaft 300 from rotating randomly. In the present embodiment, the specific central angles corresponding to the first inclined portion 311 and the second inclined portion 313 are not limited in range and can be selected as needed. As a specific example, as shown in Figure 11 and Figure 12 indicated, the corresponding central angle of the first inclined portion 311 is 20 degrees, and the corresponding central angle of the second inclined portion 313 is 5 degrees.

[0097] In other embodiments, the corresponding central angle of the convex portion 4111 of the abutting portion 411 is greater than the corresponding central angle of the protrusion. The specific values of the corresponding central angle of the convex portion 4111 of the abutting portion 411 and the corresponding central angle of the protrusion are not limited, and the difference between them is also not specifically limited. As shown in Figure 12 indicated, the corresponding central angle of the convex portion 4111 of the abutting portion 411 is 115 degrees, and the corresponding central angle of the protrusion is 75 degrees. The corresponding central angle of the convex portion 4111 of the abutting portion 411 being greater than the corresponding central angle of the protrusion allows the protrusion to stably abut on the convex portion 4111 of the abutting portion 411.

[0098] In some other embodiments, the linkage assembly 400 extends from the rotating shaft 300 to the middle of the telescopic structure 200 to extend or retract the telescopic structure 200 from or into the hollow portion 110. In the present embodiment, the specific way in which the linkage assembly 400 extends to the middle of the telescopic structure 200 is not limited and can be selected as desired. The linkage assembly 400 extends to the middle of the telescopic structure 200 so that the telescopic structure 200 is uniformly stressed.

[0099] In some other embodiments, the linkage assembly 400 includes a linkage structure 430 that moves along the length of the vertical beam body 100 with the linkage assembly 400. The linkage structure 430 is disposed in the hollow portion 110 and has a force applying segment 431. The telescopic structure 200 has a receiving portion 210 protruding towards the end of the vertical beam body 100, and the force applying segment 431 is accommodated in the receiving portion 210 to extend or retract the telescopic structure 200 from or into the hollow portion 110.

[0100] In the present embodiment, the specific shape of the linkage structure 430 and the force applying segment 431 is not limited and can be selected as desired. As shown in Figures 8 to 9 , the linkage structure 430 is an L-shaped plate, and the force applying segment 431 is a long strip-shaped plate. It is obvious that this is only exemplary and not the only one.

[0101] As shown in Figure 13 , the telescopic structure 200 has a receiving portion 210 protruding towards the end of the vertical beam body 100, that is, the telescopic structure 200 has a receiving portion 210 protruding upwards. The force applying segment 431 is disposed in the receiving portion 210 to extend or retract the telescopic structure 200 from or into the hollow portion 110, and this connection is simple, easy to disassemble and replace.

[0102] In some other embodiments, the receiving portion 210 and the force applying segment 431 are both long strip-shaped, and the receiving portion 210 and the force applying segment 431 are disposed along the transverse direction of the vertical beam body 100. That is, the receiving portion 210 and the force applying segment 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 force applying segment 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.

[0103] In some other embodiments, the force applying segment 431 is configured to abut against the receiving portion 210 to drive the telescopic structure 200 to move when the telescopic structure 200 is retracted into the hollow portion 110. That is, as shown in Figure 7 , the force applying segment 431 abuts against the upper side of the receiving portion 210 at this time and drives the telescopic structure 200 to move upwards. That is, the force applying segment 431 is the power for the telescopic structure 200 to move upwards.

[0104] In some other embodiments, the force applying segment 431 is configured to disengage from the abutting receiving portion 210 when the telescopic structure 200 is extended from the hollow portion 110. As shown in Figure 8 , the force applying segment 431 is first moved downward to disengage from the upper side of the receiving portion 210, and the telescopic structure 200 is moved downward under the action of the second spring 500 to extend from the hollow portion 110. That is, as shown in Figure 7 , Figure 8 and Figure 13 , the distance between the upper side of the receiving portion 210 and the lower side of the receiving portion 210 defines the range of the upward and downward movement of the linkage assembly 400 and the telescopic structure 200. The linkage assembly 400 controls the movement of the telescopic structure 200 in such a way that the telescopic structure 200 is uniformly stressed.

[0105] In some other embodiments, the linkage structure 430 further has a conducting segment 432, the two ends of the conducting segment 432 being connected with the force applying segment 431 and the linkage shaft 410 respectively. In the present embodiment, the shape of the conducting segment 432 is not limited and can be selected as required. As a specific embodiment, as shown in Figure 9 , the conducting segment 432 is in the shape of a plate. It is obvious that this is only exemplary and not the only one.

[0106] In some other embodiments, the linkage shaft 410 extends two symmetrical clamping portions 413, and the conducting segment 432 is clamped between the two clamping portions 413. In the present embodiment, the specific shape of the clamping portion 413 is not limited and can be selected as required. As shown in Figure 9 , the clamping portion 413 is a clamping claw extending from the linkage shaft 410, and the conducting segment 432 is clamped between the two clamping claws. Moreover, the middle part of the conducting segment 432 is fixed to the linkage shaft 410 by a screw, which further prevents the linkage shaft 410 from rotating.

[0107] In some other embodiments, the vertical beam body 100 has a connecting structure 120 in the shape of a circular arc at the end thereof along the length direction. The vertical beam assembly 10 further comprises a first fixing seat 600, which is arranged at the opening 30 of the refrigerator. The first fixing seat 600 has a first guide slot 610 in the shape of a circular arc, the opening of which faces forward. The first fixing seat 600 is used to guide the connecting structure 120 to enter into or disengage from the first guide slot 610 along the inner side wall of the first guide slot 610 during the opening and closing of the door body 20 of the refrigerator 1.

[0108] In the present embodiment, the end of the vertical beam body 100 opposite to the hollow portion 110 has a connecting structure 120 in the shape of a circular arc, that is, the two ends of the vertical beam body 100 along the length direction respectively have the connecting structure 120 and the hollow portion 110. As a specific embodiment, as shown in Figure 16As 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.

[0109] 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 4 , Figure 17 , Figure 18 and Figure 19 As shown, the central angle of the arc-shaped connecting structure 120 is 90°.

[0110] like Figure 6 , Figure 17 , Figure 18 and Figure 19 As shown, the first fixing seat 600 is used to fix the vertical beam body 100, and the first fixing seat 600 is also used to prevent cold air from leaking out of the refrigerator 1. Since the first guide groove 610 and the connecting structure 120 are both arc-shaped, as Figure 6 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.

[0111] 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 14 , Figure 17 , Figure 18 and Figure 19 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 14 , Figure 17 , Figure 18 and Figure 19 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.

[0112] 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 17 , Figure 18 and Figure 19As shown in FIG. 11, the angle of the central angle corresponding to the lead-in section 611 is 15°. The recess 4112 of the interference portion 411 corresponds to a central angle that is 15° larger than the central angle corresponding to the connecting portion 312. The two angles are of the same size, which makes it easier for the connecting structure 120 to be guided into the first fixing seat 600 at the initial stage. That is, at this stage, the telescopic structure 200 is still located in the hollow portion 110, and the curvature of the lead-in section 611 is smaller than the curvature of the tangential section 612, so the connecting structure 120 is easily guided into the first fixing seat 600.

[0113] In some other embodiments, the first fixing seat 600 further comprises a guide block 620 arranged in the first guide groove 610. The end of the connecting structure 120 is provided with a long and strip-shaped guide groove 121, which has an opening facing away from the rotating shaft 300, so that the guide block 620 is guided into or out of the guide groove 121 during the opening and closing of the door body 20 of the refrigerator 1.

[0114] In the present embodiment, the specific shape of the guide block 620 can be selected as needed. As a specific embodiment, as shown in FIGS. 11, 12 and 13, the shape of the guide block 620 is arc-shaped, which facilitates the guide block 620 to be guided into the guide groove 121. Figure 4 、 Figure 17 、 Figure 18 and Figure 19 As shown in FIGS. 11, 12 and 13, the guide block 620 is arc-shaped, which facilitates the guide block 620 to be guided into the guide groove 121.

[0115] The guide groove 121 has an opening facing away from the rotating shaft 300, that is, the opening 1211 of the guide groove and the rotating shaft 300 are located on the two sides of the vertical beam body 100. As shown in FIGS. 11, 12 and 13, Figure 4 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. As shown in FIGS. 11, 12 and 13, Figure 17 、 Figure 18 and Figure 19 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 17 、 Figure 18 and Figure 19 FIGS. 11, 12 and 13 show the process of the connecting structure 120 being guided into or out of the first guide groove 610 along the inner side wall of the first guide groove 610, and also show the process of the guide block 620 being guided into or out of the guide groove 121. As shown in FIGS. 11, 12 and 13, Figure 17 、 Figure 18 and Figure 19 the guide block 620 makes it easier for the connecting structure 120 to be guided into the first fixing seat 600, avoiding the connecting structure 120 from deviating from the track.

[0116] In some other embodiments, as shown in FIGS. 14 and 15, Figure 14 、 Figure 17、 Figure 18 and Figure 19 As shown in FIG. 6, the guide block 620 is located at the end of the introduction section 611 along the introduction direction. That is, when the vertical beam body 100 is rotated by 10° to 20°, the guide block 620 just contacts the opening 1211 of the guide slot, which facilitates the smooth introduction of the connecting structure 120 into the first fixing seat 600.

[0117] In some other embodiments, the guide block 620 and the guide slot 121 are both arc-shaped, and during the sliding of the guide block 620 along the guide slot 121, the guide block 620 at least contacts one of the inner side walls of the guide slot 121. This can limit the rotation track of the connecting structure 120, so as to accurately introduce the vertical beam body 100 into the refrigerator 1.

[0118] In some other embodiments, the vertical beam assembly 10 further comprises a second fixing seat 700, which is arranged at the opening 30 of the refrigerator. The second fixing seat 700 has a second guide slot 710 with an opening facing forward and in an arc shape. The second guide slot 710 is used to make the hollow part 110 introduced into or separated from the second guide slot 710 along the second guide slot 710 during the opening and closing of the door body 20 of the refrigerator 1. The hollow part 110 is in an arc shape.

[0119] In the present embodiment, the corresponding arc of the second guide slot 710 is not limited, and can be selected as needed. As a specific embodiment, as shown in FIG. 7, the corresponding arc of the second guide slot 710 is 90°, which makes the hollow part 110 completely accommodated in the second guide slot 710. Figure 15

[0120] In some other embodiments, the telescopic structure 200 is configured to be extended when the connecting structure 120 is rotated to the end of the introduction section 611, which avoids the extension structure increasing the friction of the introduction of the vertical beam body 100, so that the connecting structure 120 can be smoothly introduced into the second fixing seat 700,

[0121] In some other embodiments, the corresponding central angle range of the connecting structure 120, the first guide slot 610, the second guide slot 710 and the hollow part 110 is 80° to 110°. This makes the connecting structure 120 be able to rotate along the first guide slot 610 when the vertical beam body 100 is rotated by 80° to 110°, and makes the connecting structure 120 be completely accommodated in the first guide slot 610. Similarly, this makes the hollow part 110 be able to rotate along the second guide slot 710, and makes the hollow part 110 be completely accommodated in the second guide slot 710. This can further reduce the cold leakage of the refrigerator 1.

[0122] ​In some other embodiments, the shape of the telescopic structure 200 is arc-shaped, the inner side wall of the first guide slot 610 is adapted to the outer side wall of the connecting structure 120, and the inner side wall of the second guide slot 710 is adapted to the outer side wall of the telescopic structure 200.

[0123] The inner side wall of the first guide slot 610 is adapted to the outer side wall of the connecting structure 120, that is, as shown in Figure 6 and Figure 19 , the inner side wall of the first guide slot 610 is uniformly spaced from the outer side wall of the connecting structure 120, and the gap between the inner side wall of the first guide slot 610 and the outer side wall of the connecting structure 120 is small.

[0124] The inner side wall of the second guide slot 710 is adapted to the outer side wall of the telescopic structure 200, that is, as shown in Figure 7 , the inner side wall of the second guide slot 710 is uniformly spaced from the outer side wall of the hollow portion 110, and the gap between the inner side wall of the second guide slot 710 and the outer side wall of the hollow portion 110 is small. This can avoid the leakage of the refrigerator 1, so that the air blocking effect of the refrigerator 1 is better.

[0125] According to the second aspect of the present application, the present application also provides a refrigerator 1 comprising the vertical beam assembly 10 for the door body 20 of the refrigerator 1 according to any one of the above. Since the refrigerator 1 comprises the vertical beam assembly 10 according to any one of the above, the refrigerator 1 has the technical effects of the vertical beam assembly 10 according to any one of the above, which will not be repeated here.
