Description

Technical Field

[0001] This application relates to the field of refrigerator technology, and in particular to a spacing adjustment device, a cabinet, and a refrigerator. Background Technology

[0002] Refrigerators are common household appliances. Large-capacity refrigerators are usually designed with side-by-side doors to facilitate the storage and retrieval of items and reduce the space occupied during the opening and closing process.

[0003] The refrigerator door is connected to the refrigerator body via a hinge structure. Due to factors such as processing errors of parts, installation process errors, deformation during foaming, twisting and deformation during transportation, and deformation during use, the distance between the door and the refrigerator body is inconsistent when the side-by-side door is closed. That is, the two doors cannot be aligned on the front side, resulting in product defects and affecting the user experience. Utility Model Content

[0004] This application provides a spacing adjustment device, a cabinet, and a refrigerator, aiming to provide a device that facilitates adjusting the spacing between the door and the cabinet when the door is closed.

[0005] In a first aspect, some embodiments of this application provide a spacing adjustment device, including a housing, a support assembly, and an adjustment assembly. The housing has an adjustment cavity, and a first insertion hole and a second insertion hole communicating with the adjustment cavity. A portion of the support assembly is located within the adjustment cavity, and another portion of the support assembly extends out of the adjustment cavity via the first insertion hole. A portion of the adjustment assembly is inserted into the second insertion hole, and a portion of the adjustment assembly is located within the adjustment cavity. The adjustment assembly is configured to have a switchable first state and a second state.

[0006] When the adjustment component is in the first state, the part of the adjustment component located in the adjustment cavity is connected to the support component in a transmission manner, so as to drive the support component to adjust the insertion depth in the first insertion hole.

[0007] When the adjustment component is in the second state, it prevents the adjustment component from driving the support component to adjust the insertion depth within the first insertion hole.

[0008] Optionally, the adjusting assembly includes a first transmission member and an adjusting rod. The first transmission member is located within the adjusting cavity and is used for driving the connection to the support assembly. One end of the adjusting rod is inserted into a second insertion hole, and the other end of the adjusting rod is located within the adjusting cavity.

[0009] When the adjusting assembly is in the first state, the adjusting rod moves to the first position along the axial direction of the second insertion hole. The adjusting rod is connected to the first transmission component to drive the first transmission component to rotate, thereby adjusting the insertion depth of the support assembly in the first insertion hole.

[0010] When the adjusting component is in the first state, the adjusting rod moves to the second position along the axial direction of the second insertion hole, the adjusting rod disengages from the first transmission component, and / or the adjusting rod is restricted from rotation.

[0011] Optionally, the spacing adjustment device further includes a first meshing tooth and a second meshing tooth. The first meshing tooth is provided on the inner side of the housing, and the adjusting rod is provided with the second meshing tooth. When the adjusting rod is in the second position, the second meshing tooth engages with the first meshing tooth to prevent the adjusting rod from rotating. When the adjusting rod is in the first position, the second meshing tooth disengages from the first meshing tooth.

[0012] Optionally, the adjusting cavity includes a first chamber and a second chamber, which are sequentially connected along the axial direction of the second insertion hole. At least a portion of the first transmission member is located within the second chamber, and the adjusting rod is inserted into the second insertion hole, the first chamber, and the second chamber at a first position. A second limiting portion is provided on the portion of the adjusting rod located in the first chamber along the axial direction of the second insertion hole to prevent the adjusting rod from disengaging from the second insertion hole in a direction away from the second chamber. The adjusting assembly includes a second elastic member, which is disposed between the side wall of the first chamber near the second chamber and the second limiting portion along the axial direction of the second insertion hole, and the second elastic member is in a compressed state to place the adjusting rod in the initial state of the second position.

[0013] Optionally, along the axial direction of the second insertion hole, the housing is provided with a first meshing tooth on the inner wall of the first chamber away from the second chamber, and the second limiting part is provided with a second meshing tooth on the side facing the second insertion hole.

[0014] Optionally, along the axial direction of the second insertion hole, a third limiting part is provided at one end of the adjusting rod located in the adjusting cavity, and a fourth limiting part is provided in the first transmission member. At least when the adjusting rod is in the first position, the third limiting part and the fourth limiting part are inserted and adapted to each other, so that the adjusting rod drives the first transmission member to rotate.

[0015] Optionally, the cross-sectional shape of the third limiting part of the adjusting rod in the section perpendicular to the axial direction is rectangular.

[0016] Optionally, the fourth limiting part is a rectangular hole adapted to the third limiting part.

[0017] Optionally, when the adjusting rod is in the second position, the third limiting part and the fourth limiting part are disengaged from the plugging and fitting state.

[0018] Optionally, the adjustment assembly further includes a second transmission component and a rotating component. The second transmission component is located within the adjustment cavity and has a threaded hole. The first transmission component has an external thread structure and is adapted to be inserted into the threaded hole. The first transmission component is used to drive the second transmission component to slide axially along the second insertion hole. Rotatably mounted within the adjustment cavity, the second transmission component is used to drively connect with the support assembly through the rotating component to adjust the insertion depth of the support assembly in the first insertion hole.

[0019] Optionally, the adjusting assembly includes a first positioning shaft, which is fixedly connected to a second transmission component. The rotating component is provided with a first positioning groove, and the first positioning shaft is inserted into and adapted to the first positioning groove to drive the rotating component to rotate.

[0020] Optionally, the support assembly includes a support body and a second positioning shaft. A portion of the support body is inserted into a first insertion hole, and a portion of the support body is located in an adjustment cavity and fixedly connected to the second positioning shaft. The rotating member is provided with a second positioning groove, and the second positioning shaft is inserted into and adapted to the second positioning groove so that the rotating member is used to adjust the insertion depth of the support body in the first insertion hole.

[0021] Optionally, the rotating component includes a rotating shaft, a first rotating plate, and a second rotating plate. The first rotating plate has a first positioning groove and a second positioning groove at both ends. The second rotating plate also has a first positioning groove and a second positioning groove at both ends. The first and second rotating plates are spaced apart along the axial direction of the rotating shaft and connected to it, forming a clearance groove between the first and second rotating plates.

[0022] Optionally, the support assembly includes a support body, a first limiting portion, and a first elastic member. A portion of the support body is inserted into the first insertion hole, while a portion of the support body and the first limiting portion are located within an adjustment cavity. The first limiting portion is connected to the support body to prevent the support body from disengaging from the adjustment cavity via the first insertion hole. The first elastic member is located within the adjustment cavity, on the side of the support body away from the first insertion hole, and is compressed between the support body and the housing. The support body located within the adjustment cavity serves to drive the adjustment assembly, allowing the adjustment assembly to adjust the insertion depth of the support body within the first insertion hole in a first state.

[0023] Optionally, the support assembly also includes a support member, the support body having a third insertion hole corresponding to the first insertion hole, one end of the support member being inserted into the third insertion hole, and the other end of the support member being located on the outside of the housing.

[0024] Optionally, one end of the support body is located outside the housing via the first insertion hole, and the adjustment component is used to adjust the extension length of the support body through the first insertion hole.

[0025] Optionally, the support body is provided with a fifth limiting part for inserting and adapting to the first elastic element.

[0026] Optionally, the housing has a sixth limiting part in the adjustment cavity, which is used to insert and adapt the first elastic member.

[0027] Optionally, the first and second insertion holes are located on the same side of the housing.

[0028] Secondly, some embodiments of this application provide a refrigerator, including a frame body, a door, and the spacing adjustment device mentioned above. The frame body has a storage compartment inside, and the door is hinged to the frame body for opening or closing the storage compartment. The spacing adjustment device is installed on the side of the door away from the hinge. When the door closes the storage compartment, a support assembly is positioned outside the housing and supported by the frame body, used to adjust the spacing between the door and the frame body.

[0029] Thirdly, some embodiments of this application provide a refrigerator, including the cabinet described in the second aspect.

[0030] The technical solutions provided in this application have the following advantages compared with the prior art:

[0031] In the adjustment cavity of the spacing adjustment device, since the adjustment component is connected to the support component by transmission, and the adjustment component is also inserted into the second insertion hole, by rotating or pressing the adjustment component in the first state at the second insertion hole, the support component is moved accordingly through the transmission connection structure, thereby adjusting the insertion depth of the support component in the first insertion hole, so as to adjust the length of the protruding end of the support component outside the adjustment cavity.

[0032] When the spacing adjustment device is installed between the door and the main frame, it is located on the side of the door away from the hinge. With the door in the closed storage compartment, the exposed portion of the support assembly at the first insertion hole (i.e., the end of the support assembly located outside the cavity) is supported by the main frame. Thus, when the insertion depth of the support assembly in the first insertion hole is adjusted by the adjustment device, the length of the end of the support assembly located outside the housing changes accordingly, thereby adjusting the spacing between the door and the main frame, i.e., adjusting the flatness of the door when closed.

[0033] Taking a refrigerator with a side-by-side door structure as an example, the spacing adjustment device is installed on the two relatively close sides of the two opposite doors. The flatness of the closed storage compartment (i.e., in the closed state) can be flexibly adjusted through the two adjustment components so that the outer sides of the two doors away from the main body of the refrigerator frame are aligned when closed, which has better flatness and aesthetics, so as to give users a better user experience.

[0034] Compared to related technical solutions that use bolts to adjust the closing distance between the door and the frame, the distance adjustment device provided in this application allows for adjustment of the support distance of the support component by rotating or moving the adjustment assembly. This method is simpler than the previous approach of first rotating the bolts and then tightening them with nuts.

[0035] Furthermore, since the spacing adjustment device is an independent unit, it can be directly connected to the door body using bolts or rivets, making installation simple. Alternatively, the spacing adjustment device can be fixedly installed inside the door body before foaming, and the spacing adjustment device inside the door body can be reinforced by secondary extrusion through the foaming process. In this case, only the adjustment end of the adjustment component and the support component of the support component protrude from the door body, resulting in high connection strength and good aesthetics.

[0036] Based on this, since the adjustment component has a switchable first state and a second state, in the first state, the adjustment component can flexibly adjust the insertion depth of the support component in the first insertion hole, that is, flexibly adjust the extension length of the support component outside the adjustment cavity, correspondingly adjusting the flatness of the door in the closed state. In the second state, it can prevent the adjustment component from driving the support component to adjust the insertion depth in the first insertion hole. This avoids accidental activation of the adjustment component in the second state, which would affect the flatness of the door, allowing the door to maintain a good flatness state for a long time.

[0037] The spacing adjustment device provided in this application embodiment can be applied to refrigerators to facilitate adjustment of the door gap between side-by-side or single-door refrigerators, while also improving aesthetics. Furthermore, this spacing adjustment device can also be applied to any structure or device with a door to adjust the door gap spacing when closed; there are no limitations on its application.

[0063] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0064] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0065] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0067] Please see Figures 1 to 14 This application provides a spacing adjustment device, a cabinet, and a refrigerator, aiming to provide a device that facilitates adjusting the spacing between the door and the cabinet when the door is closed.

[0068] like Figure 1 and Figure 2 As shown, the refrigerator includes a cabinet, which comprises a frame body 100 and a door 200. The frame body 100 has a storage compartment 110 inside, which can be at least one of a refrigerator compartment, a freezer compartment, a variable temperature compartment, and a soft-freeze compartment, used to extend the shelf life of pre-set items within the storage compartment 110. The door 200 is hinged to the frame body 100 and used to open or close the storage compartment 110.

[0069] The cabinet, including the frame body 100, door 200, and spacing adjustment device 300, can be a regular wardrobe or bookcase with hinged or double doors. Alternatively, the cabinet can be a refrigerator or a high-temperature storage device, which allows items in the storage compartment 110 to be preserved under preset temperature and humidity conditions; there are no limitations on this.

[0070] Large-capacity refrigerators are usually set up as follows Figure 1 The double-door structure shown facilitates the storage and retrieval of items in the storage room 110 and reduces the space occupied during the opening process.

[0071] However, during the production, transportation, and use of refrigerators, due to factors such as processing errors of parts, installation process errors, deformation of foaming process, twisting and deformation during transportation, and deformation during use, the distance between the door 200 and the frame body 100 of the double-door refrigerator is inconsistent when the door is closed. That is, the two door 200 cannot be aligned on the front side, which leads to product defects and affects the user experience.

[0072] Based on this, such as Figure 2 and Figure 3 As shown, the refrigerator also includes a spacing adjustment device 300, which is installed on the side of the door 200 away from the hinge.

[0073] Reference Figure 4 and Figure 5The spacing adjustment device 300 includes a housing 310, a support assembly 320, and an adjustment assembly 330. The housing 310 has an adjustment cavity 311, and a first insertion hole 312 and a second insertion hole 313 communicating with the adjustment cavity 311. A portion of the support assembly 320 is located within the adjustment cavity 311, and another portion of the support assembly 320 extends out of the adjustment cavity 311 via the first insertion hole 312. A portion of the adjustment assembly 330 is inserted into the second insertion hole 313, and a portion of the adjustment assembly 330 is located within the adjustment cavity 311. The adjustment assembly 330 is configured to have a switchable first state and a second state.

[0074] For example, the support assembly 320 may include a support body 321 and a first limiting portion 3211. A portion of the support body 321 is inserted into a first insertion hole 312, and a portion of the support body 321 and the first limiting portion 3211 are located within an adjustment cavity 311. The first limiting portion 3211 is connected to the support body 321 to prevent the support body 321 from disengaging from the adjustment cavity 311 through the first insertion hole 312. The support body 321 located within the adjustment cavity 311 is used for transmission connection to the adjustment assembly 330, so that the adjustment assembly 330 adjusts the support body 321 in a first state.

[0075] The support body 321 and the first limiting part 3211 can be integrally formed, that is, the support body 321 is provided with a limiting protrusion (i.e., the first limiting part 3211). In the adjustment cavity 311, the support body 321 with the limiting protrusion has a larger outline size so as to limit and cooperate with the inner edge of the first insertion hole 312, thereby preventing the part of the support body 321 inserted in the first insertion hole 312 from continuing to move outward, and preventing the support body 321 from leaving the adjustment cavity 311 from the first insertion hole 312.

[0076] Alternatively, the support body 321 and the first limiting part 3211 can also be a detachable, separate structure. That is, within the adjustment cavity 311, by installing the first limiting part 3211 at a corresponding position on the support body 321, the first limiting part 3211 can engage with the inner edge of the first insertion hole 312, thereby preventing the portion of the support body 321 inserted into the first insertion hole 312 from moving outwards, thus preventing the support body 321 from detaching from the adjustment cavity 311. When connecting the support body 321 and the first limiting part 3211, the first limiting part 3211 can be installed by snap-fit ​​or screw connection; there is no limitation on this method.

[0077] For example, the first limiting part 3211 is a flange ring or flange frame structure. The first limiting part 3211 can be set to have a large thickness in the axial direction of the first insertion hole 312 so as to form an integral structure with the support body 321.

[0078] It should be noted that the support body 321 can be located entirely within the first insertion hole 312 without being exposed. In this case, other exposed support structures can be connected to the end of the support body 321 located in the first insertion hole 312 to support it between the door body 200 and the box frame body 100. Thus, the distance between the door body 200 and the box frame body 100 can be adjusted by adjusting the depth of the support body 321 within the first insertion hole 312.

[0079] Alternatively, one end of the support body 321 can be exposed outside the housing 310 through the first insertion hole 312 to provide support between the door body 200 and the box frame body 100. In this case, the extension length of the exposed support body 321 can be adjusted by the insertion depth of the support body 321 in the first insertion hole 312, thereby adjusting the distance between the door body 200 and the box frame body 100.

[0080] The adjustment component 330 is configured to have a switchable first state and a second state.

[0081] When the adjustment component 330 is in the first state, the part of the adjustment component 330 located in the adjustment cavity 311 is connected to the support component 320 (or support body 321) in a transmission connection, so as to drive the support component 320 to adjust the insertion depth in the first insertion hole 312.

[0082] When the adjusting component 330 is in the second state, it prevents the adjusting component 330 from driving the support component 320 to adjust the insertion depth within the first insertion hole 312. The method of preventing this in the second state could be to prevent the adjusting component 330 from rotating or moving. Alternatively, it could prevent the adjusting component 330 from driving the support component 320 to adjust its position by disengaging the transmission between the adjusting component 330 and the support component 320.

[0083] Based on this, within the adjustment cavity 311, since the adjustment component 330 is connected to the support body 321 via a transmission connection, and the adjustment component 330 is also inserted into the second insertion hole 313, by rotating or pressing the adjustment component 330 in its first state at the second insertion hole 313, the support body 321 is moved accordingly via the transmission connection structure, thereby adjusting the insertion depth of the support body 321 within the first insertion hole 312. This adjusts the length of the protruding end of the support component 320 outside the adjustment cavity 311.

[0084] When the spacing adjustment device 300 is installed between the door body 200 and the box frame body 100, the spacing adjustment device 300 is located on the side of the door body away from the hinge. When the door body 200 is in the closed storage compartment 110, the exposed portion of the support assembly 320 at the first insertion hole 312 (i.e., the end of the support assembly 320 located outside the adjustment cavity 311) is supported by the box frame body 100. Thus, when the insertion depth of the support body 321 in the first insertion hole 312 is adjusted by the adjustment assembly 330, the length of the end of the support assembly 320 located outside the housing 310 will change accordingly, thereby adjusting the spacing between the door body 200 and the box frame body 100, that is, adjusting the flatness of the door body when closed.

[0085] Taking a refrigerator with a side-by-side door structure as an example, the spacing adjustment device 300 is installed on the two relatively close sides of the two oppositely arranged doors 200. The flatness of the doors 200 when the storage compartment 110 is closed (i.e., in the closed state) can be flexibly adjusted by the two adjustment components 330, so that the outer sides of the two doors 200 away from the main body of the cabinet frame 100 are aligned when closed, which has better flatness and aesthetics, so as to give users a better user experience.

[0086] Compared to related technical solutions that use bolts to adjust the closing distance between the door body 200 and the frame body 100, the distance adjustment device 300 provided in this application embodiment can adjust the support distance of the exposed part of the support component 320 by rotating or moving the adjustment component 330. Compared to the technical solution of first rotating the bolt and then tightening the bolt with a nut, the adjustment method is simpler.

[0087] Furthermore, since the spacing adjustment device 300 is an independent unit, it can be directly connected to the door body 200 via bolts or rivets, making installation simple. Alternatively, the spacing adjustment device 300 can be fixedly installed inside the door body 200 before foaming, and the spacing adjustment device 300 inside the door body 200 can be reinforced by secondary extrusion through the foaming process. In this case, only the adjusting end of the adjusting component 330 and the supporting component 320 protrude from the door body 200, resulting in high connection strength and good aesthetics.

[0088] Based on this, since the adjusting component 330 has a switchable first state and a second state, in the first state, the adjusting component 330 can flexibly adjust the insertion depth of the support component 320 in the first insertion hole 312, that is, flexibly adjust the extension length of the support component 320 outside the adjusting cavity 311, correspondingly adjusting the flatness of the door 200 in the closed state. In the second state, it can prevent the adjusting component 330 from driving the support component 320 to adjust the insertion depth in the first insertion hole 312. This avoids accidentally touching the adjusting component 330 in the second state and affecting the flatness of the door 200, so that the door 200 can maintain a good flatness state for a long time.

[0089] It should be noted that the spacing adjustment device 300 provided in this application embodiment can be applied to refrigerators to facilitate the adjustment of door gaps in both side-by-side and single-door refrigerators, while also improving aesthetics. Furthermore, the spacing adjustment device 300 can also be applied to any structure or device with a door 200 to adjust the door gap spacing when the door 200 is closed; there are no limitations on its application.

[0090] Between the door body 200 and the box frame body 100, such as Figure 3 and 4 As shown, the support assembly 320 also includes a support member 323. The support body 321 has a third insertion hole 3212 corresponding to the first insertion hole 312. One end of the support member 323 is inserted into the third insertion hole 3212, and the other end of the support member 323 is located outside the housing 310. This allows the support member 323 to be positioned between the frame body 100 and the support body 321 when the door 200 is in the closed state.

[0091] Thus, during the process of adjusting the insertion depth of the support body 321 in the first insertion hole 312, the extension length of the support member 323 inserted in the third insertion hole 3212 can be adjusted, thereby adjusting the gap between the door body 200 and the box frame body 100 in the closed state.

[0092] For example, the support member 323 can be interference-fitted with the third insertion hole 3212 to provide good connection strength between the support member 323 inserted into the third insertion hole 3212 and the support body 321. Alternatively, by providing external threads on the outside of the support member 323 and setting the third insertion hole 3212 as a threaded hole, good connection strength between the support member 323 and the support body 321 can also be achieved.

[0093] By configuring the split support component 323 and the support body 321, and assembling the support component 323 and the support body through detachable or fixed connection, the exposed area of ​​the support body 321 is reduced, while the setting of the support component 323 makes it easy to flexibly adjust the length range of the exposed size of the support component 320. This is beneficial to improving the adaptation and adjustment range of different door gaps 200, and has a high application range and adaptability.

[0094] Alternatively, the support member 323 and the support body 321 can be fixed together by adhesive or heat fusion. Both methods prevent the support member 323 from detaching, resulting in a simple structure that is easy to manufacture and process, and providing high connection strength. No limitation is imposed on this method.

[0095] like Figure 3 As shown, the support assembly 320 also includes a buffer part 324, which is located at the end of the support member 323 away from the support body 321. The buffer part 324 can be a buffer medium such as a rubber pad or a silicone pad, used to reduce the impact intensity when the support member 323 contacts the side wall of the box frame body 100.

[0096] In some other embodiments, the support member may not be necessary. In this case, one end of the support body 321 is located outside the housing 310 via the first insertion hole 312, and the adjustment component 330 is used to adjust the extension length of the support body 321 through the first insertion hole 312. This helps to reduce the number of parts in the support component 320, thereby reducing the overall structure.

[0097] In some embodiments, such as Figure 4 and Figure 5 As shown, the adjustment assembly 330 includes a first transmission member 331 and an adjustment rod 332. The first transmission member 331 is located within the adjustment cavity 311 and is used for transmission connection to the support body 321. The adjustment rod 332 is partially inserted into the second insertion hole 313, and the adjustment rod 332 is partially located within the adjustment cavity 311.

[0098] When the adjusting component 330 is in the first state, the adjusting rod 332 moves to the first position along the axial direction of the second insertion hole 313. The adjusting rod 332 is connected to the first transmission component 331 to drive the first transmission component 331 to rotate, thereby adjusting the insertion depth of the support body 321 in the first insertion hole 312.

[0099] Thus, by setting the adjusting rod 332 to have two position states, a first position and a second position, and enabling the adjusting rod 332 to drive the first transmission member 331 to rotate in the first position, the first transmission member 331 drives the support body 321 to move within the first insertion hole 312, thereby adjusting the insertion depth of the support body 321 within the first insertion hole 312, and thus adjusting the gap size between the door body 200 and the box frame body 100.

[0100] When the adjusting component 330 is in the second state, the adjusting rod 332 moves to the second position along the axial direction of the second insertion hole 313, which can disengage the adjusting rod 332 from the first transmission member 331. At this time, even if the adjusting rod 332 is accidentally touched, it will not drive the first transmission member 331 to rotate, thereby affecting the positional accuracy of the support body 321.

[0101] Alternatively, when the adjusting rod 332 is in the second position, the rotation of the adjusting rod 332 can be prevented by the limiting structure, thereby limiting the rotation of the adjusting rod 332 when it is accidentally touched, so as to affect the positional accuracy of the support body 321.

[0102] The two aforementioned configurations of the adjusting rod 332 at the second position can be configured simultaneously. Alternatively, only one of the aforementioned configurations of the adjusting rod 332 at the second position can be configured; there is no limitation on this.

[0103] It should be noted that on the side of the second insertion hole 313 away from the adjustment cavity 311, the adjustment rod 332 can be set to an extended state so that the user can contact the adjustment rod 332 and adjust the gap size between the door body 200 and the box frame body 100.

[0104] Alternatively, the adjusting rod 332 may be located within the second insertion hole 313 and not protruding. In this case, the user needs to use a tool (such as a screwdriver or Allen wrench) to access the adjusting rod 332 within the second insertion hole 313. By turning the adjusting rod 332 at the first position, the user can drive the first transmission component 331 to adjust the insertion depth of the support body 321 within the first insertion hole 312, thereby adjusting the gap size between the door body 200 and the frame body 100.

[0105] In some embodiments, such as Figure 6 and Figure 7 As shown, the spacing adjustment device also includes a first meshing tooth 314 and a second meshing tooth 3321. The first meshing tooth 314 is provided on the inner side of the housing 310, and the second meshing tooth 332 is provided on the adjusting rod 332.

[0106] When the adjusting rod 332 is in the second position, the second meshing tooth 3321 engages with the first meshing tooth 314 to prevent the adjusting rod 332 from rotating. When the adjusting rod 332 is in the first position, the second meshing tooth 3321 disengages from the first meshing tooth 314.

[0107] Since the first meshing tooth 314 is located at the housing 310, the adjusting rod 332 in the second position causes the second meshing tooth 3321 to mesh with the first meshing tooth 314, thereby preventing the adjusting rod 332 from driving the first transmission member 331 to rotate, thus avoiding the rotation of the adjusting rod 332 when it is accidentally touched in the second position from affecting the adjustment accuracy of the support body 321.

[0108] Correspondingly, when the adjusting rod 332 moves from the second position to the first position, the adjusting rod 332 drives the second meshing tooth 3321 away from the first meshing tooth 314 until the second meshing tooth 3321 disengages from the first meshing tooth 314. At this time, the adjusting rod 332 can be smoothly rotated to drive the first transmission member 331 to rotate, thereby adjusting the insertion depth of the support body 321 in the first insertion hole 312.

[0109] For example, the adjusting lever 332 is configured to reciprocate along its axial direction to switch between a first position and a second position.

[0110] like Figure 4 and Figure 6 As shown, the adjusting cavity 311 includes a first chamber 3111 and a second chamber 3112. Along the axial direction of the second insertion hole 313, the second insertion hole 313, the first chamber 3111, and the second chamber 3112 are sequentially connected. The first transmission member 331 is at least partially located within the second chamber 3112. The adjusting rod 332 is inserted into the second insertion hole 313, the first chamber 3111, and the second chamber 3112 at a first position, so that the adjusting rod 332 is connected to the first transmission member 331 in a transmission connection. Referring to the axial direction of the second insertion hole 313... Figure 4 and Figure 7 The portion of the adjusting rod 332 located in the first chamber 3111 is provided with a second limiting part 3322 to prevent the adjusting rod 332 from disengaging from the second insertion hole 313 in a direction away from the second chamber 3112.

[0111] Based on this, such as Figure 4 and Figure 5 As shown, the adjustment assembly 330 includes a second elastic member 334. Along the axial direction of the second insertion hole 313, the second elastic member 334 is disposed between the side wall of the first chamber 3111 near the second chamber 3112 and the second limiting part 3322, and the second elastic member 334 is in a compressed state so that the adjustment rod 332 is in the second position.

[0112] Thus, the arrangement of the first chamber 3111 and the second chamber 3112 allows the adjusting rod 332 to move and switch between the first chamber 3111 and the second chamber 3112 along the axial direction of the second insertion hole 313. For example, when the adjusting rod 332 moves toward the second chamber 3112 to the first position, the adjusting rod 332 located in the second chamber 3112 is connected to the first transmission member 331, so that the adjusting rod 332 can drive the first transmission member 331 to rotate.

[0113] When the adjusting rod 332 moves to the second position away from the second chamber 3112, the adjusting rod 332 can be partially located within the second chamber 3112. That is, at this time, the adjusting rod 332 can be either connected to or disconnected from the first transmission member 331. Alternatively, the adjusting rod 332 can also be disconnected from the second chamber 3112 at the second position. That is, at this time, the adjusting rod 332 can be spaced apart from or disconnected from the first transmission member 331.

[0114] Based on this, by providing a second limiting part 3322 at the portion of the adjusting rod 332 located in the first chamber 3111, and making the second limiting part 3322 a protruding structure or a flange ring structure, the radial dimension of the second limiting part 3322 is made larger than the inner diameter of the second insertion hole 313, thereby preventing the adjusting rod 332 from disengaging from the second insertion hole 313 in a direction away from the second chamber 3112. Thus, along the axial direction of the second insertion hole 313, a second elastic member 334 in a compressed state can be provided between the side wall of the first chamber 3111 near the second chamber 3112 and the second limiting part 3322, so that a force is applied to the second limiting part 3322 of the adjusting rod 332 in a direction away from the second chamber 3112 through the second elastic member 334, and the adjusting rod 332 is in the initial state of the second position.

[0115] Taking the second insertion hole 313, the first chamber 3111 and the second chamber 3112 as being distributed from back to front as an example, the adjusting rod 332 returns to the second position under the action of the second elastic member 334, so that the first meshing tooth 314 and the second meshing tooth 3321 mesh and match, thereby preventing the adjusting rod 332 from driving the first transmission member 331 to rotate.

[0116] It should be noted that, along the axial direction of the second insertion hole 313, the second meshing tooth 3321 can be disposed on the side of the second limiting part 3322 away from the second chamber 3112, and the first meshing tooth 314 is disposed on the edge of the second insertion hole 313 near the second chamber 3112. The first meshing tooth 314 and the second meshing tooth 3321 can be engaged or disengaged along the axial direction.

[0117] Alternatively, along the radial direction of the second insertion hole 313, the second meshing tooth 3321 can be disposed radially outside the second limiting part 3322 or the adjusting rod 332. On the side of the second insertion hole 313 axially close to the second chamber 3112, a first meshing tooth 314 is provided radially inside the second insertion hole 313, so that the second meshing tooth 3321 and the first meshing tooth 314 can mesh and fit together radially, and switch the position of the adjusting rod 332 axially between the second position and the first position, so that the second meshing tooth 3321 and the first meshing tooth 314 can switch between the meshing state and the non-meshing state, which is not limited.

[0118] For example, such as Figure 6 and Figure 8 As shown, along the axial direction of the second insertion hole 313, the housing 310 has a first meshing tooth 314 on the inner wall of the first chamber 3111 on the side away from the second chamber 3112. (Refer to...) Figure 7 and Figure 9 The second limiting part 3322 is provided with a second meshing tooth 3321 on the side facing the second insertion hole 313. That is, the first meshing tooth 314 and the second meshing tooth 3321 are set by the original structure of the housing 310 and the adjusting rod 332 to limit the adjusting rod 332 in the second position, which is simple in structure.

[0119] In this configuration, multiple first meshing teeth 314 are circumferentially spaced along the edge of the second insertion hole 313. Correspondingly, multiple second meshing teeth 3321 are circumferentially spaced along the second limiting portion 3322. This arrangement allows the multiple first meshing teeth 314 to mesh and engage with the multiple second meshing teeth 3321, thereby increasing the limiting resistance on the adjusting rod 332. For example, the tooth shape of the first meshing teeth 314 and the second meshing teeth 3321 can be triangular, rectangular, hemispherical, or semi-circular, etc., and there is no limitation thereto.

[0120] Because the adjusting rod 332 continuously adjusts the gap between the door body 200 and the box frame body 100 during rotation, the arrangement of multiple first meshing teeth 314 and multiple second meshing teeth 3321 allows the adjusting rod 332 to achieve meshing and engagement of the first meshing teeth 314 and the second meshing teeth 3321 at multiple positions around the circumference, which helps to improve the adjustment accuracy of the adjusting rod 332 in multiple locked states (i.e., the second position).

[0121] The number of the first meshing teeth 314 and the second meshing teeth 3321 can be flexibly adjusted according to actual needs. That is, the more first meshing teeth 314 and the more second meshing teeth 3321 there are, the higher the adjustment accuracy of the adjusting rod 332 in the locked state. The fewer the first meshing teeth 314 and the more second meshing teeth 3321 there are, the simpler the component structure becomes. This also helps to increase the resistance of the adjusting rod 332 in the locked state by increasing the meshing contact area and meshing depth between the individual first meshing teeth 314 and the second meshing teeth 3321, thus ensuring that a good gap size is maintained between the door body 200 and the box frame body 100.

[0122] When the transmission connection adjustment rod 332 and the first transmission component 331 are connected, such as Figure 7 and Figure 9 As shown, along the second insertion hole 313 (as Figure 4 As shown in the diagram, the adjusting rod 332 has a third limiting part 3323 at one end of the adjusting cavity 311. (Refer to...) Figure 4 and Figure 10 The first transmission member 331 is provided with a fourth limiting part 3311. At least when the adjusting rod 332 is in the first position, that is, when the first meshing tooth 314 and the second meshing tooth 3321 are in a non-meshing state, the third limiting part 3323 and the fourth limiting part 3311 are inserted and adapted to each other so that the adjusting rod 332 can drive the first transmission member 331 to rotate.

[0123] For example, the third limiting part 3323 is the insertion end of the adjusting rod 332 in the length direction, and correspondingly, the fourth limiting part 3311 is the insertion hole of the first transmission member 331 facing the second insertion hole 313. The insertion end and the insertion hole are fitted together, and the insertion end of the adjusting rod 332 is inserted into the insertion hole of the first transmission member 331. The insertion end is not a cylindrical structure; for example, it is a polyprism structure such as a triangular prism, quadrangular prism, or pentagonal prism, and the insertion hole has a corresponding triangular hole, rectangular hole, or pentagonal hole in its cross-section, i.e., the insertion hole is not a circular hole structure. This ensures that the fitted third limiting part 3323 and the fourth limiting part 3311 do not slip, thereby allowing the adjusting rod 332 to drive the first transmission member 331 to rotate.

[0124] Alternatively, the third limiting part 3323 can be set as a plug-in hole, and the fourth limiting part 3311 can be set as a plug-in end. As long as slippage between the adjusting rod 332 and the first transmission member 331 can be avoided so that transmission can be carried out between the two components, it is acceptable. For example, the third limiting part 3323 and the fourth limiting part 3311 can be a spline shaft adapter structure.

[0125] For example, in a cross-section perpendicular to the axial direction, the cross-sectional shape of the third limiting part 3323 of the adjusting rod 332 is rectangular. Correspondingly, the fourth limiting part 3311 is a rectangular hole or a positive-direction hole that fits into the third limiting part 3323. This allows the third limiting part 3323 to be inserted into the fourth limiting part 3311 and prevents relative rotation between the adjusting rod 332 and the first transmission member 331. That is, when the adjusting rod 332 rotates, it can synchronously drive the first transmission member 331 to rotate.

[0126] When the adjusting rod 332 is in the initial state of the second position, the third limiting part 3323 and the fourth limiting part 3311 can disengage from the plug-in adaptation state. In this way, even if the adjusting rod 332 rotates under the action of external force, the adjusting rod 332 and the first transmission member 331 are not in a transmission connection state at this time, that is, the first transmission member 331 will not rotate synchronously to affect the position of the support body 321.

[0127] In other words, along the axial direction of the second insertion hole 313, the insertion fit dimension between the third limiting part 3323 and the fourth limiting part 3311 is defined as the first depth dimension, and the movement distance of the adjusting rod 332 between the first position and the second position is defined as the second depth dimension, and the second depth dimension is greater than the first depth dimension. This ensures that when the adjusting rod 332 is in the first position, the third limiting part 3323 and the fourth limiting part 3311 are in an insertion fit state, and when the adjusting rod 332 moves to the second position, the third limiting part 3323 and the fourth limiting part 3311 are in a non-insertion fit state, such as when the third limiting part 3323 is not inserted into the fourth limiting part 3311.

[0128] That is, through the above-mentioned redundant configuration, the adverse effects of external force acting on the adjustment rod 332 on the gap size between the door body 200 and the box frame body 100 are further avoided.

[0129] It should be noted that the torque between the adjusting component 330 and the supporting component 320 can be adjusted by changing the transmission ratio between them. Setting the transmission ratio between the adjusting component 330 and the supporting component 320 to be greater than 2 improves the adjustment accuracy in the direction from the adjusting component 330 to the supporting component 320. Furthermore, when an external force acts on the adjusting component 330 from the supporting component 320 side, a larger force is required to cause rotation or displacement at the adjusting component 330. Thus, even if the adjusting component 330 does not have an internal transmission limiter, the rotation or displacement caused by the reverse force from the supporting component 320 side on the adjusting component 330 can be reduced.

[0130] In some other embodiments, regardless of whether the adjusting rod 332 is in the first or second position, the third limiting part 3323 and the fourth limiting part 3311 can be in a plug-in adaptation state. That is, there is no need to deliberately adjust the plug-in adaptation depth between the third limiting part 3323 and the fourth limiting part 3311, which facilitates the production, processing and assembly of the parts. In some embodiments, meshing tooth structures can be provided at the first transmission member 331 and the support body 321 respectively, so that the first transmission member 331 and the support body 321 can contact and mesh. For example, the included angle between the rotation axis of the first transmission member 331 and the moving direction of the support body 321 can be 0°, acute angle, right angle, obtuse angle or 180°, which is not limited.

[0131] Or, such as Figure 4 and Figure 5 As shown, the adjustment assembly 330 also includes a second transmission member 335 and a rotating member 336. The second transmission member 335 is located within the adjustment cavity 311, as shown in the figure. Figure 11 The second transmission component 335 is provided with a threaded hole 3351. Correspondingly, as... Figure 4 and Figure 11 As shown, the first transmission member 331 has an external thread structure and is adapted to be inserted into the threaded hole 3351. The first transmission member 331 is used to drive the second transmission member 335 to slide axially along the second insertion hole 313.

[0132] The adjusting rod 332, in its first position, rotates to drive the first transmission member 331 to rotate synchronously. Within the threaded hole 3351, the rotating first transmission member 331 causes the second transmission member 335 to slide axially along the second insertion hole 313. If the adjusting rod 332 is rotated clockwise, the second transmission member 335 moves closer to the second insertion hole 313. If the adjusting rod 332 is rotated counterclockwise, the second transmission member 335 moves away from the second insertion hole 313.

[0133] At this time, the mating structure between the first transmission component 331 and the second transmission component 335 through internal and external threads can also be regarded as a special meshing transmission structure.

[0134] The first transmission member 331 has a flange ring at at least one end along the axial direction. The outer diameter of the flange ring is larger than the inner diameter of the threaded hole 3351, so as to prevent the second transmission member 335 from disengaging from the first transmission member 331 along the axial direction.

[0135] For example, such as Figure 4 and Figure 6 As shown, the adjustment chamber 311 also includes a third chamber 3113 and a fourth chamber 3114. The fourth chamber 3114 is used to install the support assembly 320.

[0136] Reference Figure 4 and Figure 5The rotating component 336 is rotatably mounted in the adjusting cavity 311 (such as the third chamber 3113). The second transmission component 335 is connected to the support body 321 via the rotating component 336 and is used to adjust the insertion depth of the support body 321 in the first insertion hole 312.

[0137] Since the second transmission member 335 is configured to reciprocate axially along the second insertion hole in the second chamber 3112, the support body 321 can also be configured to reciprocate axially within the fourth chamber 3114 and the first insertion hole 312. In this case, the position where the second transmission member 335 and the support body 321 contact the rotating member 336 can be set as a linear rack and pinion structure, and the rotating member 336 can be a gear structure meshing with both, so that the second transmission member 335 can drive the support body 321 to reciprocate via the rotating member 336.

[0138] When the second transmission component moves away from the second insertion hole 313 along the axial direction of the second insertion hole 313, it drives the support body 321 to insert deeper into the first insertion hole 312, or drives the support body 321 to extend a longer distance from the first insertion hole 312 out of the housing 310, so as to adjust and increase the gap distance between the door body 200 and the box frame body 100.

[0139] When the second transmission component moves axially toward the second insertion hole 313, it drives the support body 321 to move from the first insertion hole 312 toward the fourth chamber 3114. During this process, the support body 321 is inserted into the first insertion hole 312 more shallowly, or the support body 321 extends out of the housing 310 from the first insertion hole 312 by a shorter dimension, so as to adjust and reduce the gap distance between the door body 200 and the box frame body 100.

[0140] Or, such as Figure 11 As shown, the adjustment assembly 330 includes a first positioning shaft 3352, which is fixedly connected to a second transmission component 335. The two can be an integrally formed structure or connected by screws, rivets, or heat fusion. Figure 5 and Figure 12 As shown, the rotating component 336 is provided with a first positioning groove 3361, and the first positioning shaft 3352 is inserted and adapted to the first positioning groove 3361 to drive the rotating component 336 to rotate.

[0141] Correspondingly, such as Figure 13 As shown, the support assembly 320 includes a second positioning shaft 3213, which is fixedly connected to the support body 321. (Combined with...) Figure 5 and Figure 12The rotating component 336 is provided with a second positioning groove 3362, and the second positioning shaft 3213 is inserted into and adapted to the second positioning groove 3362 so that the rotating component 336 can be used to adjust the insertion depth of the support body 321 in the first insertion hole 312.

[0142] For example, the first positioning groove 3361 and the second positioning groove 3362 can be a waist-shaped hole structure or a strip-shaped hole structure with an opening on one side along the length direction.

[0143] As the second transmission member 335 and the support body 321 move in a straight line, they are engaged by the insertion of a shaft and a groove. Between the rotating member 336 and the second transmission member 335, a sliding displacement occurs between the first positioning shaft 3352 and the inner wall of the first positioning groove 3361, allowing the linearly moving first positioning shaft 3352 and the second transmission member 335 to drive the rotating member 336 to rotate through the inner wall of the first positioning groove 3361.

[0144] Correspondingly, between the rotating component 336 and the supporting body 321, the second positioning shaft 3213 slides against the inner wall of the second positioning groove 3362, allowing the rotating component 336 to drive the second positioning shaft 3213 and the supporting body 321 to extend and retract along the first insertion hole 312 via the inner wall of the second positioning groove 3362, thereby adjusting the gap size between the door body 200 and the box frame body 100. Thus, through the arrangement of the first positioning shaft 3352, the first positioning groove 3361, the second positioning shaft 3213, and the second positioning groove 3362, while satisfying the meshing transmission between the second transmission component 335, the rotating component 336, and the supporting body 321, multiple toothed structures are unnecessary, resulting in a simple structure that is easy to manufacture.

[0145] In some embodiments, such as Figure 12 As shown, the rotating component 336 includes a rotating shaft 3363, a first rotating plate 3364, and a second rotating plate 3365.

[0146] The rotating shaft 3363 can be a recessed structure or a raised cylindrical structure, so that the rotating member 336 can be supported and installed in the third chamber 3113 for meshing transmission between the second transmission member 335 and the support body 321.

[0147] Reference Figure 12 The first rotating plate 3364 has a first positioning groove 3361 and a second positioning groove 3362 at both ends. The second rotating plate 3365 also has a first positioning groove 3361 and a second positioning groove 3362 at both ends. The first rotating plate 3364 and the second rotating plate 3365 are spaced apart along the axial direction of the rotating shaft portion 3363 and connected to the rotating shaft portion 3363, so as to form a clearance groove 3366 between the first rotating plate 3364 and the second rotating plate 3365.

[0148] By connecting a first rotating plate 3364 and a second rotating plate 3365 at intervals at both ends of the axial direction of the rotating shaft 3363, two first positioning grooves 3361 are aligned axially, and two second positioning grooves 3362 are aligned axially, that is, by using double-layer plates, the structural strength of the rotating component 336 at the first positioning groove 3361 and the second positioning groove 3362 is improved.

[0149] Based on this, a clearance groove 3366 is formed between the first rotating plate 3364 and the second rotating plate 3365, which are spaced apart, saving material in the manufacture of the rotating component 336. Near the first positioning groove 3361, the clearance groove 3366 can accommodate the connection structure between the first positioning shaft 3352 and the second transmission component 335. Near the second positioning groove 3362, the clearance groove 3366 can accommodate the connection structure between the second positioning shaft 3213 and the support body 321. This prevents the aforementioned connection structure from contacting the rotating component 336 during rotation, thus hindering power transmission and improving the adjustment range of the support assembly 320 between the minimum and maximum gap sizes.

[0150] For the support assembly 320, due to machining errors in the parts and the existence of assembly gaps, the length of the support body 321 or support member 323 extending out of the first insertion hole 312 has a certain error. Based on this, as Figure 4 and Figure 5 As shown, the support assembly 320 also includes a first elastic element 325, which is located within the adjustment cavity 311 (i.e., the fourth chamber 3114). The first elastic element 325 is located on the side of the support body 321 away from the first insertion hole 312, and is compressed between the support body 321 and the housing 310. This allows the compressed first elastic element 325 to apply a force toward the first insertion hole 312 to the support body 321.

[0151] Thus, even if there is only an assembly gap between the support assembly 320 and the adjustment assembly 330, the first elastic element 325 allows the support body 321 to disregard the assembly gap and maintain its maximum extension capacity in the corresponding state, thereby accurately controlling the gap between the door 200 and the frame body 100. Furthermore, at the instant the door closes, the outer end of the support body 321 or the support element 323 will contact the side wall of the frame body 100 in a short time, allowing the support assembly 320 to withstand a greater impact. Because there is only an assembly or fitting gap between the support bodies 321, the compressed first elastic element 325, combined with the assembly or fitting gap and the cooperation of the first elastic element 325, creates a buffer structure for the support body 321, effectively buffering and absorbing the impact force received by the door 200 at the moment of closing, thereby improving the stability of the device and the entire refrigerator.

[0152] It should be noted that in the embodiments of this application, the first elastic element 325 and the second elastic element 334 can be springs, which have a simple structure.

[0153] The second elastic element 334 is sleeved on the adjusting rod 332. Correspondingly, along the axial direction of the second insertion hole 313, annular gaskets are provided at both ends of the second elastic element 334 to increase the contact area between the second elastic element 334 and the second limiting part 3322 and the inner wall of the housing 310.

[0154] To facilitate the positioning and installation of the first elastic element 325, such as Figure 4 and Figure 14 As shown, the support body 321 is provided with a fifth limiting part 3214, which is used to insert and adapt to the first elastic member 325.

[0155] For example, the fifth limiting part 3214 can be a groove-shaped structure or a blind hole structure. For instance, the supporting body 321 has a fifth limiting part 3214 at one end opposite to the third insertion hole 3212. This fifth limiting part 3214 can be a blind hole structure or a stepped hole structure, so that a portion of the first elastic member 325 can be inserted into the fifth limiting part 3214 to facilitate the positioning and installation of the first elastic member 325.

[0156] Correspondingly, such as Figure 4 and Figure 6 As shown, the housing 310 has a sixth limiting part 315 in the adjustment cavity 311 (i.e., the fourth chamber 3114), which is used to insert and adapt the first elastic member 325. That is, one end of the first elastic member 325 is inserted and adapted to the fifth limiting part 3214, and the other end of the first elastic member 325 is inserted and adapted to the sixth limiting part 315, so that the first elastic member 325 can be stably compressed between the support body 321 and the housing 310.

[0157] If the fifth limiting part 3214 is a slotted structure, then the sixth limiting part 315 is a corresponding plug-in post structure, so that one end of the first elastic member 325 is sleeved on the sixth limiting part 315.

[0158] In some other embodiments, such as Figure 4 As shown, taking the fifth limiting part 3214 as an example of an insertion groove structure, the support body 321 is also provided with a seventh limiting part 3215 within the fifth limiting part 3214. This seventh limiting part 3215 is an insertion post structure. This allows one end of the first elastic member 325 to be sleeved on the seventh limiting part 3215 and inserted into the fifth limiting part 3214. This limits abnormal deformation of the first elastic member 325 during compression, thereby providing a stable supporting elastic force to the support body 321.

[0159] It should be noted that, in this embodiment, the first insertion hole 312 and the second insertion hole 313 are located on the same side of the housing 310. This ensures that when the door 200 is closed, the exposed support assembly 320 and adjustment assembly 330 are both located on the back side of the door 200, resulting in a better aesthetic appearance.

[0160] Alternatively, the first insertion hole 312 and the second insertion hole 313 can be provided on adjacent sides of the housing 310. In this way, even when the door 200 is closed, the gap spacing of the door 200 can be adjusted through the side-exposed adjustment component 330, which is more convenient.

[0161] Among them, such as Figure 5 and Figure 6 As shown, the housing 310 includes two parts with a split structure, so as to have an adjustment chamber that includes a first chamber 3111, a second chamber 3112, a third chamber 3113 and a fourth chamber 3114 inside, so as to facilitate the installation of corresponding components in each chamber inside the housing 310.
