Detailed implementation manners

[0067] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0068] An exemplary embodiment of the present disclosure provides an adjustment device 41. Refer to Figures 1 - 16 , the adjustment device 41 includes a base 411, a first adjustment member 412, an elastic member 413, and a second adjustment member 414.

[0069] Refer to Figures 8 - 11 , the base 411 has a receiving space 4111 and an opening 4112 communicating with the receiving space 4111. Exemplarily, the base 411 can be set as a housing structure formed by enclosing, the receiving space 4111 can be arranged inside the base 411, and the receiving space 4111 communicates with the outside of the base 411 through the opening 4112.

[0070] Exemplarily, the base 411 can also be set as an open housing structure, the receiving space 4111 is formed in the base 411, and the receiving space 4111 communicates with the outside of the base 411 through the opening 4112.

[0071] The first adjustment member 412 is arranged in the receiving space 4111 and connected to the base 411. The base 411 plays a role in fixing the first adjustment member 412. The connection between the first adjustment member 412 and the base 411 can fix the first adjustment member 412 in the receiving space 4111 and prevent the first adjustment member 412 from moving around in the receiving space 4111.

[0072] At least a part of the second adjustment member 414 is arranged in the receiving space 4111. The second adjustment member 414 can extend out of the base 411 through the opening 4112, and the second adjustment member 414 is connected to the elastic member 413.

[0073] At least the second adjustment member 414 is configured to separate from the first adjustment member 412 by overcoming the elastic force of the elastic member 413 when subjected to an external force. In the separated state, the second adjustment member 414 can change its relative position with respect to the first adjustment member 412 under the action of the external force. When the external force disappears, under the elastic force of the elastic member 413, the second adjustment member 414 abuts against the first adjustment member 412, and the second adjustment member 414 can abut against the first adjustment member 412 at different relative positions to change the length of the second adjustment member 414 extending out of the base 411.

[0074] The adjusting device 41 of this embodiment can be disposed, for example, on the door body of the refrigerator. The refrigerator is provided with at least two door bodies. After the two door bodies are closed, there will be a problem that the closing degrees of the two door bodies are different, which will further result in a height difference between the two door bodies and affect the user experience. The relative height of the two door bodies can be adjusted by the adjusting device 41, effectively solving the height difference problem caused by the different closing degrees of the two door bodies. When it is found that there is a height difference between the door bodies, the user can apply an external force to the second adjusting member 414 to overcome the elastic force of the elastic member 413 and separate from the first adjusting member 412. At this time, the relative position between the second adjusting member 414 and the first adjusting member 412 can be flexibly changed under the action of the external force. After adjusting to the appropriate position, the external force is removed. Under the elastic force of the elastic member 413, the second adjusting member 414 is in close contact with the first adjusting member 412, so as to be fixed at a new relative position, realizing the change of the length of the second adjusting member 414 extending out of the base 411. In this way, the height of the door body can be finely adjusted by adjusting the extending length of the second adjusting member 414, so that the two door bodies are at the same horizontal height after being closed, greatly improving the overall aesthetics of the refrigerator appearance and enhancing the user experience.

[0075] See Figures 8 - 11 , in some embodiments, a first mating structure 4123 is provided on the first adjusting member 412, and a second mating structure 4141 is provided on the second adjusting member 414. The second mating structure 4141 can move relative to the first mating structure 4123 when subjected to an external force. When the second adjusting member 414 abuts against the first adjusting member 412 at different relative positions, the first mating structure 4123 and the second mating structure 4141 have different mating states. When the second adjusting member 414 changes its relative position with respect to the first adjusting member 412 under the action of an external force, the mating states between the first mating structure 4123 and the second mating structure 4141 are different at different positions. Through the mating states between the first mating structure 4123 and the second mating structure 4141 at different positions, the two refrigerator door bodies with uneven closing degrees and obvious height differences can achieve height adjustment, be conveniently adjusted to the same height, solve the problem of the height difference between the two door bodies, and are easy to operate. The user can adjust them by himself.

[0076] See Figures 10 - 16, in some embodiments, one of the first mating structure 4123 and the second mating structure 4141 includes at least one adjustment tooth 414111, and the other of the first mating structure 4123 and the second mating structure 4141 includes at least one adjustment slot 412311. Exemplarily, when the first mating structure 4123 includes at least one adjustment tooth 414111, the second mating structure 4141 includes at least one adjustment slot 412311. When the first mating structure 4123 includes at least one adjustment slot 412311, the second mating structure 4141 includes at least one adjustment tooth 414111. The adjustment tooth 414111 can be inserted into an adjustment slot 412311, and the insertion direction of the adjustment tooth 414111 is consistent with the telescopic direction of the second adjusting member 414. After the adjustment tooth 414111 is inserted into the adjustment slot 412311, the relative rotation between the first adjusting member 412 and the second adjusting member 414 can be restricted. At the same time, when the external force disappears, under the elastic force of the elastic member 413, the first mating structure 4123 abuts against the second mating structure 4141, and the movement of the second adjusting member 414 in its telescopic direction is restricted, so that the first adjusting member 412 and the second adjusting member 414 can maintain abutment, avoiding the adjustment tooth 414111 from disengaging from the adjustment slot 412311, and ensuring the stability of the second adjusting member 414 abutting against the first adjusting member 412 at different relative positions.

[0077] In some embodiments, the first mating structure 4123 includes at least one first adjustment tooth and at least one first adjustment slot, the second mating structure 4141 includes at least one second adjustment tooth and at least one second adjustment slot, a second adjustment tooth can be inserted into a first adjustment slot in a matching manner, and a first adjustment tooth can be inserted into a second adjustment slot in a matching manner, so as to facilitate the abutment of the first adjusting member 412 and the second adjusting member 414 at different positions, and further facilitate adjusting the length of the second adjusting member 414 extending out of the base 411.

[0078] In some embodiments, a plurality of adjusting teeth 414111 are provided, and at least two of the adjusting teeth 414111 have different lengths. An adjusting groove 412311 can cooperate with the adjusting teeth 414111 having different lengths to change the length of the second adjusting member 414 extending out of the base 411. Exemplarily, when the door body device is provided on the door body of a refrigerator and it is necessary to adjust the length of the second adjusting member 414 extending out of the base 411, the adjusting groove 412311 can be engaged with the longer adjusting teeth 414111. Under the action of the elastic force of the elastic member 413, the second adjusting member 414 is in close contact with the first adjusting member 412. At this time, the cooperation between the longer adjusting teeth 414111 and the adjusting groove 412311 makes the length of the second adjusting member 414 extending out of the base 411 relatively long. When the door body is closed, the second adjusting member 414 abuts against the box body 1 of the refrigerator, so as to adjust the door body to be farther away from the box body 1 of the refrigerator, thereby realizing the adjustment of the height of the door body after closing.

[0079] In some embodiments, a plurality of adjusting grooves 412311 are provided, and at least two of the adjusting grooves 412311 have different depths. An adjusting tooth 414111 can cooperate with the adjusting grooves 412311 having different depths to change the length of the second adjusting member 414 extending out of the base 411. Exemplarily, when the door body device is provided on the door body of a refrigerator and it is necessary to adjust the length of the second adjusting member 414 extending out of the base 411, the adjusting tooth 414111 can be engaged with the shorter adjusting groove 412311. Under the action of the elastic force of the elastic member 413, the second adjusting member 414 is in close contact with the first adjusting member 412. At this time, the cooperation between the shorter adjusting groove 412311 and the adjusting tooth 414111 makes the length of the second adjusting member 414 extending out of the base 411 relatively long. When the door body is closed, the second adjusting member 414 abuts against the box body 1 of the refrigerator, so as to adjust the door body to be farther away from the box body 1 of the refrigerator, thereby realizing the adjustment of the height of the door body after closing.

[0080] In some embodiments, the adjusting teeth 414111 can be set as one or a combination of at least two of rectangular teeth, arc teeth, and tapered teeth to improve the applicability of the adjusting device 41.

[0081] Exemplarily, when the first matching structure 4123 contacts different positions of the second matching structure 4141, the adjustable range of the length of the second adjusting member 414 extending out of the base body is 0 mm - 3 mm.

[0082] See Figures 10 - 16, in some embodiments, one of the first mating structure 4123 and the second mating structure 4141 includes at least one adjustment tooth group 41411, that is, the number of the adjustment tooth groups 41411 can be set to one, two or more. One adjustment tooth group 41411 includes a plurality of adjustment teeth 414111 arranged at intervals in the circumferential direction. In one adjustment tooth group 41411, the lengths of the plurality of adjustment teeth 414111 in the circumferential direction gradually decrease. The other of the first mating structure 4123 and the second mating structure 4141 includes at least one adjustment tooth groove group 41231, that is, the number of the adjustment tooth groove groups 41231 can be set to one, two or more. One adjustment tooth groove group 41231 includes a plurality of adjustment grooves 412311 arranged at intervals in the circumferential direction. In one adjustment tooth groove group 41231, the depths of the plurality of adjustment grooves 412311 in the circumferential direction gradually decrease. With such a setting form, the lengths of the plurality of adjustment teeth 414111 in the adjustment tooth group 41411 are consistent with the decreasing direction of the depths of the plurality of adjustment grooves 412311 in the adjustment tooth groove group 41231 in the circumferential direction. During the adjustment process, when the second adjusting member 414 separates from the first adjusting member 412 under the action of an external force against the elastic force of the elastic member 413 and rotates circumferentially to change the relative position, due to the gradual change characteristics of the adjustment teeth 414111 and the adjustment grooves 412311 in the circumferential direction, the length of the second adjusting member 414 extending out of the base 411 can gradually increase or gradually decrease, realizing regular step-by-step adjustment, so as to facilitate the user to adjust the closing degree of the door body to a suitable position. Exemplarily, when the first mating structure 4123 includes two adjustment tooth groups 41411, the second mating structure 4141 includes two adjustment tooth groove groups 41231, so that when the second adjusting member 414 abuts against the first adjusting member 412, at least two adjustment teeth 414111 are in contact with at least two adjustment grooves 412311 at the same time, thereby improving the stability when the second adjusting member 414 abuts against the first adjusting member 412 at different positions.

[0083] In some embodiments, the first mating structure 4123 includes a first helical surface, and the second mating structure 4141 includes a second helical surface. When the second mating structure 4141 abuts against the first mating structure 4123 at different relative positions, different positions of the second helical surface abut against different positions of the first helical surface. The positioning after the second mating structure 4141 abuts against the first mating structure 4123 is realized through the frictional force after the first helical surface contacts the second helical surface, avoiding relative sliding after the first helical surface abuts against the first helical surface. With such a setting, it is beneficial to the fine adjustment of the length of the second adjusting member 414 extending out of the base 411, and the adjustment accuracy can be improved. Exemplarily, when different positions of the first helical surface contact the second helical surface, the adjustable range of the length of the second adjusting member 414 extending out of the base body is 0 mm - 3 mm.

[0084] In some embodiments, a first damping structure is provided on the first helical surface. Exemplarily, the first damping structure can be set as minute protrusions or grooves distributed on the first helical surface. These protrusions or grooves extend along the helical trajectory. The protrusions can be in shapes such as hemispherical, conical, etc., and the grooves can be in shapes such as square, trapezoidal, etc. With such a design, the damping function can be effectively achieved without affecting the normal cooperation between the first helical surface and the second helical surface.

[0085] The first damping structure can be set as rubber. Rubber has good flexibility, so that when it is squeezed and rubbed by the second helical surface, it can undergo a certain degree of deformation, thereby generating a damping force, and at the same time, it will not cause damage to the second helical surface. When the user rotates the second adjusting member 414, the first damping structure interacts with the second helical surface, and the generated damping force enables the user to feel the resistance feedback. The user can precisely control the speed and strength of the adjustment. Exemplarily, when the user needs to finely adjust the height of the refrigerator door body, the second adjusting member 414 can be slowly rotated to achieve precise adjustment and avoid over-adjustment caused by too fast adjustment.

[0086] The first damping structure enhances the stability after adjustment. After being adjusted to a suitable position, due to the presence of the damping structure, the relative sliding resistance between the second helical surface and the first helical surface increases. This makes the second adjusting member 414 less likely to be displaced under the influence of factors such as vibrations generated by the frequent opening and closing of the refrigerator door body and external force collisions. Even during long-term use, the adjusted position can be maintained stable, ensuring that the refrigerator door body is always in the adjusted closed state.

[0087] In some embodiments, a second damping structure is provided on the second helical surface.

[0088] Exemplarily, the second damping structure can be set as minute protrusions or grooves distributed on the second helical surface. These protrusions or grooves extend along the helical trajectory. The protrusions can be in shapes such as hemispherical, conical, etc., and the grooves can be in shapes such as square, trapezoidal, etc. With such a design, the damping function can be effectively achieved without affecting the normal cooperation between the second helical surface and the first helical surface.

[0089] The second damping structure can be set as rubber. Rubber has good flexibility, so that when it is squeezed and rubbed by the first helical surface, it can deform to a certain extent, thereby generating a damping force, and at the same time, it will not cause damage to the first helical surface. When the user rotates the second adjusting member 414, the second damping structure interacts with the first helical surface, and the generated damping force enables the user to feel the resistance feedback. The user can accurately control the speed and strength of the adjustment. Exemplarily, when the user needs to finely adjust the height of the refrigerator door body, the second adjusting member 414 can be slowly rotated to achieve precise adjustment and avoid over-adjustment caused by too fast adjustment.

[0090] The second damping structure enhances the stability after adjustment. After the second adjusting member 414 is adjusted to the appropriate position, due to the existence of the damping structure, the relative sliding resistance between the second helical surface and the first helical surface increases. This makes the second adjusting member 414 less likely to displace when affected by factors such as vibrations and external collisions caused by the frequent opening and closing of the refrigerator door body. Even during long-term use, the adjusted position can be maintained stable, ensuring that the refrigerator door body is always in the adjusted closed state.

[0091] In some embodiments, a first damping structure is provided on the first helical surface, and a second damping structure is provided on the second helical surface. The first damping structure can be set as a protrusion or a groove, and the second damping structure can be set as a protrusion or a groove to increase the sliding resistance between the second helical surface and the first helical surface and prevent the second adjusting member 414 from displacing relative to the first adjusting member 412 after adjustment.

[0092] See Figures 10 - 16 , in some embodiments, the second adjusting device 41 includes an adjusting portion 4142 and an extending portion 4143. At least part of the adjusting portion 4142 is disposed in the accommodating space 4111 and the adjusting portion 4142 can extend out of the base 411 through the opening 4112. Exemplarily, the adjusting device 41 is disposed on the door body of the refrigerator. When the door body is closed, the adjusting portion 4142 abuts against the box body 1 of the refrigerator, and the closing degree of the door body is controlled by adjusting the length of the adjusting portion 4142 extending out of the base 411. The first end of the extending portion 4143 is connected to the adjusting portion 4142, and the extending portion 4143 can be integrally formed with the adjusting portion 4142. The extending portion 4143 passes through the first adjusting member 412, and the second end of the extending portion 4143 is connected to the elastic member 413. The second elastic member 413 overcomes the elastic force of the elastic member 413 under the action of an external force, so that the second elastic member 413 is separated from the first elastic member 413. At this time, the elastic member 413 undergoes elastic deformation. When the external force disappears, under the action of the elastic force of the elastic member 413, the second adjusting member 414 abuts against the first adjusting member 412 at different relative positions to change the length of the adjusting portion 4142 extending out of the base 411, thereby facilitating the user to adjust the closing degree of the door body to an appropriate position.

[0093] In some embodiments, the second mating structure 4141 is disposed on the adjusting portion 4142. One end of the elastic member 413 abuts against the second end of the extending portion 4143, and the other end of the elastic member 413 abuts against the first adjusting member 412. The elastic member 413 is disposed between the first adjusting member 412 and the second end of the extending portion 4143. Exemplarily, the elastic member 413 can be configured as a spring or an elastic rubber member. The second adjusting member 414 is configured such that when it is stretched by an external force, the length of the second adjusting member 414 extending out of the base 411 becomes longer. At this time, the second end of the extending portion 4143 compresses the elastic member 413, and the elastic member 413 undergoes elastic deformation under the compressive force. When the external force disappears, under the elastic force of the elastic member 413, the second adjusting member 414 moves inwardly into the base 411 to abut against the first adjusting member 412, so that the first mating structure 4123 and the second mating structure 4141 are engaged. By engaging the first mating structure 4123 and the second mating structure 4141 at different positions, the length of the second adjusting member 414 extending out of the base 411 is different. Furthermore, when the adjusting device 41 is disposed on the door body, different closing degrees of the door body can be achieved by engaging the first mating structure 4123 and the second mating structure 4141 at different positions.

[0094] In some embodiments, the first adjusting member 412 includes a first sleeve 4121 and an end plate 4211. The end plate 4211 is disposed at one end of the first sleeve 4121 away from the opening 4112. The elastic member 413 abuts against the end plate 4211, so that when the second adjusting member 414 is stretched under the action of an external force, both ends of the elastic member 413 respectively abut against the end plate 4211 and the second end of the extending portion 4143 to apply an elastic force to the second adjusting member 414. The adjusting portion 4142 includes an adjusting head 41421 and a second sleeve 41422. The adjusting head 41421 extends out of the base 411, and the second sleeve 41422 is disposed at one end of the adjusting head 41421 facing the first adjusting member 412. When the adjusting device 41 is disposed on the door body of the refrigerator, in the closed state of the door body, the adjusting head 41421 abuts against the box body 1 of the refrigerator.

[0095] In some embodiments, since the end face areas of the first sleeve 4121 and the second sleeve 41422 are relatively large, the first mating structure 4123 is disposed on the end face of the first sleeve 4121, and the second mating structure 4141 is disposed on the end face of the second sleeve 41422, so that the structural dimensions of the first mating structure 4123 and the second mating structure 4141 can be set larger, which is beneficial to ensuring the structural strength of the first mating structure 4123 and the second mating structure 4141, and enabling the closing degree of the door body to be maintained stable under frequent opening and closing of the door body.

[0096] In some embodiments, the first sleeve 4121 and the second sleeve 41422 are sleeved with each other. The first engaging structure 4123 is disposed on the side surface of the first sleeve 4121 facing the second sleeve 41422. The interior of the first sleeve 4121 is hollow. The first engaging structure 4123 is disposed on the inner surface of the first sleeve 4121. The second engaging structure 4141 is disposed on the side surface of the second sleeve 41422 facing the first sleeve 4121. The second sleeve 41422 passes through the interior of the first sleeve 4121. The second engaging structure 4141 is disposed on the outer surface of the second sleeve 41422. The hollow design of the first sleeve 4121 reduces the overall weight of the adjusting device 41 and provides a stable track for the movement of the second sleeve 41422, which can reduce the shaking of the second adjusting member 414 during the adjustment process, enabling better cooperation between the first engaging structure 4123 and the second engaging structure 4141 and facilitating the adjustment of the length of the second adjusting member 414 extending from the base 411.

[0097] In some embodiments, a fixing seat 415 is provided at the second end of the extension portion 4143. The fixing seat 415 is connected to the extension portion 4143. The fixing seat 415 is provided with a connection hole, and the connection hole is provided as an internal threaded hole. The second end of the extension portion 4143 is provided with an external thread that mates with the connection hole. The second end of the extension portion 4143 is rotatably inserted into the connection hole to be connected to the fixing seat 415.

[0098] The elastic member 413 abuts against the fixing seat 415. A limiting structure 4151 is disposed on the end surface of the fixing seat 415 facing the first adjusting member 412. The elastic member 413 is connected to the limiting structure 4151. The limiting structure 4151 is used to limit the elastic member 413. With this arrangement, when the second adjusting member 414 is pulled by an external force, the fixing seat 415 compresses the elastic member 413, and the limiting structure 4151 can ensure that the elastic member 413 always remains in the correct position, avoiding deviation or inclination during the compression process. When the external force disappears, the elastic member 413 exerts an elastic force on the fixing seat 415. Due to the precise limitation of the position of the elastic member 413 by the limiting structure 4151, the elastic member 413 can stably push the second adjusting member 414 to abut against the first adjusting member 412, facilitating the accurate cooperation between the first engaging structure 4123 and the second engaging structure 4141 after adjustment, so as to facilitate the adjustment to ensure that the refrigerator door body can maintain the same height when closed.

[0099] In some embodiments, the limiting structure 4151 is configured as an annular limiting groove, which is conducive to accurately constraining the position of the elastic member 413, preventing the elastic member 413 from radial displacement during compression and rebound, ensuring that the elastic force always acts stably along the axial direction, and greatly improving the stability and reliability of the adjustment device 41. The setting of the annular limiting groove makes the installation of the elastic member 413 more convenient. The installer only needs to embed the elastic member 413 into the annular limiting groove to quickly complete the positioning, greatly improving the installation efficiency.

[0100] In some embodiments, the first matching structure 4123 is disposed at the end of the first adjusting member 412 away from the opening 4112, the second matching structure 4141 is disposed at the extension 4143 and is located at the side of the first adjusting member 412 away from the opening 4112, one end of the elastic member 413 abuts against the second end of the extension 4143, and the other end of the elastic member 413 abuts against the base 411. The elastic member 413 is disposed between the end of the base 411 away from the opening 4112 and the second end of the extension 4143. The second adjusting member 414 is configured to compress the elastic member 413 through the second end of the extension 4143 when subjected to external force and internal pressure, and at this time, the second matching structure 4141 moves in a direction away from the first adjusting member 412, so that the second matching structure 4141 is separated from the first matching structure 4123. When the external force disappears, the first matching structure 4123 and the second matching structure 4141 are matched under the elastic force of the elastic member 413. By cooperating at different positions of the first cooperating structure 4123 and the second cooperating structure 4141, the second adjusting member 414 can extend out of the base 411 to different lengths. When the adjusting device 41 is set on the door body, different degrees of closing of the door body can be achieved through the cooperation of the first cooperating structure 4123 and the second cooperating structure 4141 at different positions, thereby facilitating the adjustment of the height differences of different door bodies on the refrigerator to be consistent.

[0101] In some embodiments, the base 411 can be configured as a shell structure, the base 411 includes a bottom wall 4113 and a side wall 4114 connected to the edge of the bottom wall 4113, and the bottom wall 4113 and the side wall 4114 enclose a receiving space 4111. An opening 4112 is formed at one end of the side wall 4114 away from the bottom wall 4113, the first adjustment member 412 is connected to the side wall 4114 to ensure that the position of the first adjustment member 412 is fixed, the elastic member 413 is disposed between the first adjustment member 412 and the bottom wall 4113, the second adjustment member 414 is slidably matched with the side wall 4114, and the side wall 4114 plays a sliding guiding role for the second adjustment member 414, thereby avoiding the problem of displacement or shaking of the second adjustment member 414 during the adjustment process.

[0102] In some embodiments, a clamping groove 4115 is provided on the inner surface of the side wall 4114. The first adjusting member 412 includes a clamping portion 4124, and the clamping portion 4124 is clamped with the clamping groove 4115, which can effectively resist the external force acting on the first adjusting member 412, prevent the first adjusting member 412 from displacing or loosening, and the installation method is simple, which is beneficial to improving the installation efficiency.

[0103] In some embodiments, a flange 4116 is provided on the outer surface of the base 411. The flange 4116 protrudes from the outer surface of the base 411, so as to facilitate the installation of the adjusting device 41 on the door body and facilitate the positioning and sealing when the adjusting device 41 penetrates the door body. Exemplarily, the flange 4116 surrounds the outer surface of the base 411 or the flange 4116 is arranged at intervals in the circumferential direction of the outer surface of the base 411.

[0104] In some embodiments, the elastic member 413 is arranged as a tension spring. One end of the elastic member 413 is connected to the bottom wall 4113 of the base 411, and the other end of the elastic member 413 is connected to the second adjusting member 414. Under the action of an external force, when the second adjusting member 414 is stretched to extend out of the base 411, the elastic member 413 is stretched. When the external force disappears, under the elastic contraction action of the elastic member 413, the first matching structure 4123 and the second matching structure 4141 are matched. Through the matching of different positions of the first matching structure 4123 and the second matching structure 4141, the length of the second adjusting member 414 extending out of the base 411 is different. Furthermore, when the adjusting device 41 is arranged on the door body 42, different closing degrees of the door body 42 can be realized through the matching of different positions of the first matching structure 4123 and the second matching structure 4141, and then the height differences of different door bodies 42 on the refrigerator can be adjusted to be consistent.

[0105] An embodiment of the present disclosure provides a door body assembly 4. Refer to Figures 1 - 6 , the door body assembly 4 includes a door body 42 and an adjusting device 41. The adjusting device 41 adopts the adjusting device 41 as described above. The door body 42 includes a frame 421. The frame 421 is arranged at the edge of the door body 42. The adjusting device 41 is arranged on the frame 421 of the door body 42 so as to abut against the outer wall of the cavity of the electrical equipment on which the door body assembly 4 is installed. By the second adjusting member 414 of the adjusting device 41 abutting against the outer wall of the cavity of the electrical equipment, the closing degree when the door body 42 is closed is adjusted, and the problem that the heights of the door body 42 are inconsistent after closing is solved. Exemplarily, the electrical equipment on which the door body assembly 4 is installed can be set as a refrigerator or a freezer.

[0106] In some embodiments, refer to Figures 1 - 6, the frame 421 includes a cover plate 4122 which is disposed at the top of the door body 42. The cover plate 4122 includes a bent portion 42111 which is bent downward from the top of the door body 42, and the bent portion 42111 corresponds to the outer wall of the cavity of the electrical device. The adjusting device 41 is disposed on the bent portion 42111 so that when the door body 42 is closed, the second adjusting member 414 abuts against the outer wall of the cavity of the electrical device. By adjusting the length of the second adjusting member 414 extending out of the base 411, that is, adjusting the length of the second adjusting member 414 extending out of the cover plate 4122, the closing degree of the door body 42 when closed is adjusted, and further the adjustment of the height difference after different door bodies on the electrical device are closed is realized.

[0107] In some embodiments, the door body assembly 4 further includes a hinge portion 43, and the door body assembly 4 rotates relative to the hinge portion 43 to open and close the door body. The adjusting device 41 is disposed at one end of the door body assembly 4 away from the hinge portion 43 and on the top of the frame 421, so as to more effectively adjust the closing state of the door body. When the door body assembly 4 rotates around the hinge portion 43, the displacement change of the end away from the hinge portion 43 is the most obvious during the movement. Disposing the adjusting device 41 at one end of the door body assembly 4 away from the hinge portion 43 can accurately control the closing degree of the door body. Disposing the adjusting device 41 on the top of the frame 421 facilitates the second adjusting member 414 to abut against the outer wall of the cavity of the electrical device.

The user can adjust the closing degree when the first door body 2 and / or the second door body 3 are closed by stretching the length of the second adjusting member 414 extending out of the base 411. Exemplarily, when the adjusting device 41 is arranged on the first door body 2 and the height of the first door body 2 after closing is lower than the height of the second door body 3 after closing, at this time, the second adjusting member 414 abuts against the first adjusting member 412 at the initial position. By applying an external force to stretch the second adjusting member 414 to increase the length of the second adjusting member 414 extending out of the base 411, when the external force disappears, under the elastic force of the elastic member 413, the second adjusting member 414 abuts against the first adjusting member 412 at a position different from the initial position, and at this time, the length of the second adjusting member 414 extending out of the base 411 increases, so that the height of the first door body 2 after closing becomes higher and is the same as the height of the second door body 3. The adjusting device 41 can be used to adjust the heights of the first door body 2 and the second door body 3 after closing to be the same without disassembling the first door body 2 and the second door body 3.
