Description

Sliding connection device, door assembly and household appliance device

[0001] This application is based on and claims priority to Chinese Patent Application No. 202410698030.8, filed on May 31, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of household appliances, and more particularly to a sliding connection device, a door assembly, and a household appliance device. Background Technology

[0003] The door of a built-in refrigerator can be connected to the cabinet body using either a folding hinge or a pivot hinge. When the door is equipped with a pivot hinge, the refrigerator door and the cabinet door need to be set to a sliding connection. In this way, when the refrigerator is installed in the cabinet, the refrigerator door and the cabinet door can rotate relative to each other to open or close the cabinet body.

[0004] A sliding connection component and a positioning fixture are generally installed between the refrigerator door and the cabinet door. The positioning fixture needs to ensure that the sliding connection component is accurately installed in the designated position on the refrigerator door and the cabinet door.

[0005] In related technologies, the sliding parts, base, and positioning fixtures are usually molded separately. The base is then assembled to the refrigerator door, and the sliding parts are positioned and assembled to the cabinet door panel using the positioning fixture. After assembly, the positioning fixture is removed. It can be seen that manual assembly involves many steps, resulting in relatively large assembly errors.

[0006] The inclusion of any related technologies in this specification does not imply confirmation or recommendation that such related technologies constitute part of the general knowledge of any jurisdiction, or that it is reasonably expected that such related technologies will be understood, regarded as related and / or combined with other related technologies by a person skilled in the art. Summary of the Invention

[0007] One of the objectives of this application is to provide a sliding connection device to solve the technical problem of large errors in manual assembly in related technologies.

[0008] To achieve one of the above objectives, one embodiment of this application provides a sliding connection device for slidingly connecting a first door body to a second door body, including a sliding member for cooperating with the second door body and a positioning device for cooperating with the sliding member; the positioning device includes a base for slidingly cooperating with the sliding member, a positioning workpiece for positioning the sliding member on the second door body, and a separable portion connecting the base and the positioning workpiece; the base is used to cooperate with the first door body; the base, the separable portion, and the positioning workpiece are formed as one piece, and the positioning workpiece can be separated from the base through the separable portion.

[0009] Compared with related technologies, the advantages of this application are: the base and the positioning workpiece are integrally formed, and the positioning workpiece is further removed after positioning is completed, which reduces the error caused by manual assembly positioning.

[0010] As used herein, the term "comprise" and its variations, such as "comprises," "comprised," "comprising," "including," and "containing," do not exclude other features, components, elements, or steps unless the context explicitly requires otherwise. Attached Figure Description

[0026] The present application will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present application, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of this application.

[0027] The terms used herein, such as “above,” “over,” “below,” and “under,” indicating spatial relative position, are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms for spatial relative position may be intended to include different orientations of the device in use or operation other than those shown in the figures. For example, if the device in the figures is flipped, a unit described as being “below” or “under” other units or features would be located “above” other units or features. Therefore, the exemplary term “below” can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or otherwise), and the spatially related descriptive terms used herein will be interpreted accordingly.

[0028] Please refer to Figure 1. One embodiment of this application provides a sliding connection device 100. Referring to Figure 5, one embodiment of this application provides a household appliance device 1000. The household appliance device 1000 includes a built-in household appliance 200, such as a refrigerator, and a cabinet 300 for housing the built-in household appliance 200. The household appliance 200 includes a first door 210 and a cabinet body, wherein the first door 210 is used to open or close the cabinet body.

[0029] The cabinet 300 includes a second door 310 that covers the first door 210. The sliding connection device 100 is used to slide the first door 210 to the second door 310. When the second door 310 is opened, the first door 210 can be opened, thereby opening the cabinet of the household appliance 200.

[0030] As shown in Figures 2-4, the sliding connection device 100 includes a sliding member 10 for cooperating with the second door 310 and a positioning device 60 for cooperating with the sliding member 10; the positioning device 60 is used to assist the sliding member 10 in positioning itself on the second door 310.

[0031] The positioning device 60 includes a base 20 that slides with the slider 10, a positioning workpiece 30 for positioning the slider 10 on the second door 310, and a separable part 61 connecting the base 20 and the positioning workpiece 30; the base 20 is used to cooperate with the first door 210, so that the slider 10 slides with the base 20, causing the first door 210 to slide with the second door 310.

[0032] The sliding connection device 100 further includes a first fastener 40 for fixing the sliding member 10 to the second door body 310, and a second fastener 50 for fixing the base 20 to the first door body 210. Thus, the sliding member 10 is relatively fixed to the second door body 310, the base 20 is relatively fixed to the first door body 210, and the sliding member 10 slides relative to the base 20, thereby causing the first door body 210 and the second door body 310 to slide relative to each other.

[0033] Specifically, both the first fastener 40 and the second fastener 50 are screws, and both include a nut and a threaded rod. In specific embodiments, the size and detailed structure of the first fastener 40 and the second fastener 50 may differ, as long as the function of fixing and connecting them can be achieved through the threaded rod.

[0034] The base 20, the separable part 61, and the positioning workpiece 30 are integrally formed; in other words, the positioning device 60 is integrally formed. In the prior art, the base 20, the sliding member 10, and the positioning workpiece 30 are all individually formed, resulting in more assembly steps and larger errors. However, in practical applications, the positioning of the base 20 relative to the first door 210, the positioning of the base 20 relative to the sliding member 10, and the positioning of the sliding member 10 relative to the second door 310 all require accurate positioning to ensure smooth cooperation between the base 20 and the sliding member 10, thereby improving the user experience of the household appliance device 1000 during the opening and closing process.

[0035] The positioning workpiece 30 can be separated from the base 20 via the separable part 61. The base 20 and the positioning workpiece 30 are integrally formed, eliminating assembly errors. Furthermore, the positioning workpiece 30 can be separated from the base 20 via the separable part 61 and then removed after positioning is completed, without affecting the sliding connection between the base 20 and the sliding member 10.

[0036] The base 20 includes a vertical fixed plate 21 and a sliding plate 22. The fixed plate 21 is used to fix the first door body 210. The sliding plate 22 has a sliding groove 220 for the sliding member 10 to slide along a first direction. The separable part 61 is located on the fixed plate 21 near the sliding groove 220. The positioning workpiece 30 is disposed away from the sliding plate 22 from the separable part 61.

[0037] The first direction is the arrangement direction of the base 10, the separable part 61 and the positioning workpiece 30, and the first direction is also the length direction of the sliding member 10.

[0038] The base 20 and the positioning workpiece 30 are located on opposite sides of the separable part 61. After operating the separable part 61, the separation of the positioning workpiece 30 will not affect the structure of the base 10.

[0039] The fixing plate 21 includes a second mounting hole 211 for installing the second fastener 50 and a limiting structure that cooperates with the second fastener 50 to prevent the second fastener 50 from moving or falling off. As shown in Figures 5-6, the second fastener 50 is usually pre-installed on the first door body 210, and the base 20 is installed on the first door body 210 by cooperating with the second fastener 50 through the second mounting hole 211.

[0040] The limiting structure includes a locking hole 212 that connects to the second mounting hole 211. The inner diameter of the second mounting hole 211 is larger than the nut of the second fastener 50, and the inner diameter of the locking hole 212 is adapted to the outer diameter of the screw of the second fastener 50.

[0041] When fixed, the base 20 first engages with the nut of the second fastener 50 through the second mounting hole 211 with a clearance fit, so that the base 20 can be inserted between the second fastener 50 and the first door body 210. Then the base 20 is moved so that the screw of the second fastener 50 engages with the locking hole 212. The inner diameter of the locking hole 212 can be less than or equal to the outer diameter of the screw of the second fastener 50, forming an interference fit.

[0042] The positioning workpiece 30 includes a positioning plate 31 connected to the separable part 61. The positioning plate 31 is arranged along a first direction, and the positioning plate 31 is positioned and engaged with the sliding member 10 along a second direction. The first direction is perpendicular to the second direction. The thickness of the separable part 61 is thinner than that of the positioning plate 31, so the separable part 61 is easy to break.

[0043] The second direction is the thickness direction of the positioning workpiece 30 and the sliding member 10, and it is also the positioning direction of the positioning workpiece 30 and the sliding member 10.

[0044] The positioning workpiece 30 includes a first positioning structure 34 disposed on the mounting plate 31, the first positioning structure 34 being disposed toward the sliding member 10, and the sliding member 10 including a second positioning structure 14 cooperating with the first positioning structure 34.

[0045] Specifically, the first positioning structure 34 includes a positioning post 341 facing the sliding member 10, and the second positioning structure 14 includes a positioning hole 141; or the first positioning structure 34 includes a positioning hole, and the second positioning structure 14 includes a positioning post facing the positioning workpiece. The first and second positioning structures include mutually cooperating positioning posts 341 and positioning holes 141, which simplifies alignment and facilitates installation, and also makes it convenient for the positioning workpiece 30 to be pulled out of the sliding member 10 during subsequent disassembly.

[0046] After the positioning workpiece 30 and the sliding part 10 are positioned and assembled through the positioning pin and positioning hole, the fixed connection between the two can be strengthened by the snap-fit ​​structure.

[0047] The first positioning structure 34 includes a buckle 342, and the second positioning structure 14 includes a slot 142 that cooperates with the buckle 342; or, the first positioning structure 34 includes a slot, and the second positioning structure 14 includes a buckle that cooperates with the slot.

[0048] Specifically, the positioning workpiece 30 is provided with an elastic buckle 342 near the positioning post 341, and the sliding member 10 is provided with a groove 142 that cooperates with the elastic buckle 342. The elastic buckle 342 and the groove 142 are combined to enhance the stability of the connection between the two.

[0049] The positioning workpiece 30 includes a limiting post 33 disposed on the positioning plate 31 and opposite to the mounting hole 111. The limiting post 33 includes a receiving groove 331 for receiving a first fastener 40. The first fastener 40 is limited in the receiving groove 331 and cooperates with the mounting hole 111. When the positioning workpiece 30 and the sliding member 10 are pre-positioned and assembled through the first and second positioning structures, the first fastener 40 should be received into the receiving groove 331.

[0050] It should be noted that after the first fastener 40 is pre-installed in the mounting hole 111, the sliding member 10 then cooperates with the positioning workpiece 30, and the limiting post 33 of the positioning workpiece 30 needs to be sleeved on the first fastener 40 so that the receiving groove 331 can limit the nut of the first fastener 40.

[0051] The limiting post 33 includes a stepped portion 332 disposed at one end of the receiving groove 331 opposite to the mounting hole 111. The stepped portion 332 protrudes inward relative to the inner wall of the receiving groove 331. The stepped portion 332 has a stepped surface 333 facing the mounting hole. The distance between the stepped surface 333 and the mounting hole 111 is not greater than the length of the first fastener 40. The first fastener 40 has a pre-installed state. In the pre-installed state, the nut of the first fastener 40 is limited along its axial direction to the stepped surface 333, and the end of the screw is limited to the positioning rib 113.

[0052] Continuing with Figure 11, when the positioning workpiece 30 and the sliding member 10 are assembled, the first fastener 40 is pre-installed in the receiving groove 331 and the mounting hole 111. When the positioning workpiece 30 and the sliding member 10 are further assembled with the second door body 310, some wobbling may occur. To prevent the first fastener 40 from being affected and shifting, a stepped surface 333 is provided along the axial direction of the first fastener 40. Thus, the nut of the first fastener 40 is constrained axially by the stepped surface 333, and the end of the screw of the first fastener 40 is also constrained axially by the positioning rib 113. Therefore, the first fastener 40 as a whole cannot shift axially. It should be noted that the axial direction of the first fastener 40 is also the common axial direction of its nut and screw.

[0053] The inner diameter of the receiving groove 331 gradually increases along the direction close to the mounting hole 111. The first fastener 40 has a pre-installed state. In the pre-installed state, the nut of the first fastener 40 is radially limited to the inner wall surface of the receiving groove 331 near the step surface 333.

[0054] Specifically, the stepped portion 332 protrudes inward relative to the inner wall of the receiving groove 331, and the nut of the first fastener 40 is axially confined to the stepped surface 333 and located below the stepped surface 333. If the inner diameter of the inner wall of the receiving groove 331 below the stepped surface 333 is too large, the nut of the first fastener 40 may tilt radially under shaking or vibration. Therefore, setting the inner diameter of the receiving groove 331 near the stepped surface 333 to be less than or equal to the outer diameter of the nut of the first fastener 40 can hold the first fastener 40 in place. Alternatively, the inner diameter of the receiving groove 331 near the stepped surface 333 can be slightly larger than the outer diameter of the nut of the first fastener 40 by up to 3mm. Within this deviation range, the radial offset of the first fastener 40 will not affect the normal installation of the first fastener 40.

[0055] The limiting post 33 includes an outer peripheral wall 334 that surrounds the receiving groove 331 and a through groove 335 disposed on the outer peripheral wall 334. The through groove 335 penetrates the inner and outer surfaces of the outer peripheral wall 334 radially along the limiting post 33, so that the outer peripheral wall 334 includes a number of arc-shaped walls arranged at intervals along the circumferential direction. The outer peripheral wall 334 has a certain elastic deformation space, which facilitates the installation of the first fastener 40.

[0056] The sliding member 10 is sheet-shaped and includes a sliding part 12 and a mounting part 11. The sliding part 12 is slidably engaged with the sliding groove 220, and the mounting part 11 is positioned engaged with the positioning plate 31. The mounting part 11 is provided with the second positioning structure 14 for engaging with the first positioning structure 34 in the second direction.

[0057] The sliding member 10 also includes a cover portion 13 that connects to the mounting portion 11. The mounting portion 11 is provided with a mounting hole 111 that mates with the first fastener 40. After installation, in order to achieve a better aesthetic appearance, the cover portion 13 is used to cover the first fastener 40 and the mounting hole 111.

[0058] Specifically, the cover portion 13 and the mounting portion 11 have a connecting structure. The connecting mechanism is configured such that the cover portion 13 can rotate around the connecting structure to cover part of the surface of the mounting portion 11, and the connecting structure will not be broken. In other words, the thickness of the connecting structure gives it a certain connection rigidity, but it can also elastically deform to allow the cover portion 13 to cover the mounting portion 11.

[0059] In other embodiments, the cover portion 13 and the mounting portion 11 can be connected by a pivot, so that the cover portion 13 can rotate to the surface of the mounting portion 11; or, the cover portion 13 and the mounting portion 11 can be connected by a separable structure. After the sliding member 10 is assembled, the separable structure is operated to separate the cover portion 13 from the mounting portion 11, and then the cover portion 13 covers part of the surface of the mounting portion 11. Specifically, the separable structure can be a thin, easily broken structure, or a detachable snap-fit ​​structure.

[0060] The two long sides of the mounting portion 11 are formed as sliding portions 12 for sliding within the sliding groove 220 of the base 20. The cover portion 13 is connected to one short side of the mounting portion 11. The surface of the mounting portion 11 is provided with a recessed groove 110 for receiving the cover portion 13. It is understood that the recessed groove 110 does not penetrate the sliding member 10.

[0061] The mounting hole 111 is further provided in the recessed groove 110. It can be understood that the mounting hole 111 is provided to pass through the sliding member 10 so that the first fastener 40 can pass through for installation. After the cover part 13 is engaged with the recessed groove 110, it can cover the mounting hole 111 and the first fastener 40.

[0062] The sliding member 10 also includes a positioning structure 112 disposed in the mounting hole 111, the positioning structure 112 being used to pre-position the first fastener 40 in the mounting hole 111. Thus, the first fastener 40 can be pre-installed on the sliding member 10, without having to wait until the sliding member 10 and the second door body 310 are assembled before installing the first fastener 40. Furthermore, the first fastener 40, pre-positioned on the sliding member 10, is less likely to be lost and will not be confused with other fasteners of similar size and structure.

[0063] The positioning structure 112 includes a positioning rib 113 that engages with the screw of the first fastener 40. The minimum inner diameter of the positioning rib 113 is not greater than the outer diameter of the screw of the first fastener 40, and the positioning rib 113 is connected to the inner edge of the mounting hole 112. Thus, the positioning rib 113 can engage the screw of the first fastener 40, thereby achieving pre-positioning. The shape of the positioning rib 113 can be adapted to the screw to be circular, so that the inner edge of the positioning rib 113 completely matches the outer circumference of the screw, enhancing friction and increasing the bonding strength between the two.

[0064] A clearance space is formed between the positioning rib 113 and the inner edge of the mounting hole 112 to provide space for the elastic deformation of the positioning rib 113, which facilitates the installation of the first fastener 40. The positioning structure 112 includes a connecting rib 114 that connects the positioning rib 113 and the inner edge of the mounting hole.

[0065] The positioning rib 113 is used to pre-position the first fastener 40. When the first fastener 40 starts to be tightened and makes a spiral motion, if the positioning rib 113 is too stiff, it will be difficult for the operator to work, and the positioning rib 113 is easy to break. After setting the clearance space, the cooperation between the positioning rib 113 and the first fastener 40 is relatively easy, which is convenient for the operator to install. In addition, the positioning rib 113 is not easy to break, which improves the service life of the sliding part 10.

[0066] Referring to Figures 3 and 9-10, the mounting plate 31 includes a latching part 35 for positioning with the second door body 310. The latching part 35 is L-shaped and engages with the outer surface of the second door body 310 to achieve positioning of the positioning workpiece 30 and the second door body 310. The latching part 35 is used to achieve positioning between the positioning workpiece 30 and the second door body 310, thereby indirectly achieving positioning between the sliding member 10 and the second door body 310.

[0067] In another embodiment, as shown in FIG15, the mounting plate 31 includes an alignment portion 36 for aligning and positioning with a predetermined position of the second door body 310. The alignment portion 36 is used to achieve alignment and positioning between the positioning workpiece 30 and the second door body 310, thereby indirectly achieving alignment and positioning between the sliding member 10 and the second door body 310. The alignment and positioning method has a simple structure and is easy to operate.

[0068] The alignment part 36 has an alignment surface 361 for aligning and positioning with the side surface of the second door body 310. The alignment surface 361 is planar. When the alignment surface 361 is aligned with the side surface of the second door body 310 and is located on the same plane, the alignment can be directly observed, measured by hand, or measured using a ruler or other tools. This proves that the positioning workpiece 30 has been installed in place, and the first fastener 40 can be further operated.

[0069] The alignment portion 36 has an abutting surface 362 for abutting the inner surface of the second door body 310, and the alignment surface 361 is perpendicular to the abutting surface 362. The alignment portion 36 is a square plate, and the alignment surface 361 and the abutting surface 362 are adjacent outer surfaces. In this way, the abutting surface 362 abuts the inner surface of the second door body 310, while the alignment surface 361 is aligned with the side surface of the second door body 310, which is more conducive to the accurate positioning of the workpiece 30 and the second door body 310.

[0070] The positioning workpiece 30 includes two aligning portions 36 spaced apart on the same side of the positioning workpiece 30, with a through opening 363 formed between the two aligning portions 36, through which the sliding member 10 passes. The sliding member 10 includes a cover portion 13 connected to a short side of the mounting portion 11. The sliding member 10 is initially longer, and when it mates with the positioning workpiece 30, the through opening 363 can also avoid the cover portion 13.

[0071] One embodiment of this application also provides a door assembly, which includes a first door 210, a second door 310 and the sliding connection device 100, wherein the sliding member 10 and the base 20 are slidably connected to the first door 210 and the second door 310.

[0072] Referring to Figures 7-10 and 12-14, this application also provides a method for installing a door assembly, including the following installation steps:

[0073] Provide the sliding connection device 100 and assemble the sliding member 10 and the positioning device 60.

[0074] The base 20 is fixed to the first door body 210, and the sliding member 10 is fixed to the second door body 310.

[0075] By operating the separable part 61, the positioning workpiece 30 is separated from the base 20, and the positioning workpiece 30 is separated from the sliding member 10.

[0076] Assembling the sliding member 10 and the positioning device 60, in other words, assembling the sliding member 10 and the positioning workpiece 30, specifically includes:

[0077] The first fastener 40 is pre-positioned in the positioning structure 112, thus the first fastener 40 is pre-engaged with the slider 10. Then, the positioning workpiece 30 needs to be assembled with the slider 10 pre-installed with the first fastener 40. At this time, the receiving groove 331 limits the first fastener 40, and the first fastener 40 is simultaneously limited in position between the slider 10 and the positioning workpiece 30, which facilitates subsequent fixing.

[0078] It is understood that the order in which the positioning device 60, the sliding member 10, and the first fastener 40 are provided is not important; the key point is the order in which they are assembled.

[0079] Assembling the slider 10 and the positioning workpiece 30 further includes:

[0080] The positioning workpiece 30 is operated so that it rotates and shifts away from the sliding member 10 around the separable part 61. It is understood that the base 20 needs to slide and engage with the sliding member 12 in the first direction, while the positioning workpiece 30 needs to be positioned and engaged with the mounting part 11 in the second direction. The assembly directions of the two cannot be satisfied at the same time.

[0081] Therefore, it is necessary to first rotate the positioning workpiece 30 away from the sliding member 10 so that the first positioning structure 34 of the positioning workpiece 30 and the second positioning structure 14 of the mounting part 11 are separated and misaligned, so that they cannot interfere with each other, allowing the sliding member 10 to be smoothly assembled into the sliding groove 220 of the base 20 along the first direction.

[0082] The positioning workpiece 30 is operated so that it rotates and moves closer to the slider 10, and then the positioning workpiece 30 is pressed along the second direction so that it is positioned and engaged with the slider 10, wherein the first direction is perpendicular to the second direction.

[0083] Understandably, once the sliding part 12 and the sliding groove 220 are smoothly engaged, the mounting part 11 and the positioning plate 31 can be assembled. If the rotation positioning workpiece 30 is canceled, the positioning workpiece 30 will return to a position close to the sliding part 10, or the positioning workpiece 30 will be rotated in the direction close to the sliding part 10 until the first positioning structure 34 and the second positioning structure 14 are close to each other.

[0084] At this time, the positioning workpiece 30 is pressed along the second direction, and the first positioning structure 34 and the second positioning structure 14 engage. That is, the positioning post 341 engages with the positioning hole 141, and the buckle 342 engages with the slot 142, thereby realizing the engagement of the mounting plate 31 and the mounting part 11, and thus realizing the positioning engagement of the positioning workpiece 30 and the sliding part 10.

[0085] The positioning workpiece 30 and the sliding member 10 are assembled and engaged, that is, the positioning device 60 and the sliding member 10 are assembled and engaged. At this time, the nut of the first fastener 40 is limited to the receiving groove 331, and the end of the screw of the first fastener 40 is limited to the positioning structure 112.

[0086] Fixing the base 20 to the first door body 210 and fixing the sliding member 10 to the second door body 310 specifically includes:

[0087] Open the first door 210 to the first preset angle and open the second door to the second preset angle. When the positioning workpiece 30 adopts the positioning method of the buckle part 35, the first door 210 and the second door 310 need to be kept at different angles before installing the base 20. The first preset angle and the second preset angle are not equal, so as to prevent the buckle part 35 from affecting the installation of the base 20.

[0088] When the positioning workpiece 30 adopts the positioning method of the alignment part 36, the first door body 210 and the second door body 310 can maintain different angles or the same angle when the base 20 is installed, because the alignment part 36 will not interfere with the second door body 310 and affect the installation of the base 20.

[0089] The assembled sliding component 10 and positioning device 60 are moved to the first door body 210, and the base 20 is fixed to the first door body 210 by the second fastener 50.

[0090] The second fastener 50 is pre-loosened by 5-8mm. In other embodiments, the value can be other depending on the different dimensions of the second fastener 50 or the base 20, as long as the base 20 can be inserted between the second fastener 50 and the first door body 210.

[0091] After the second fastener 50 is lifted a certain distance relative to the first door body 210, the base 20 is inserted between the second fastener 50 and the first door body 210 through the second mounting hole 211. The locking hole 212 of the base 20 is moved to cooperate with the second fastener 50, and the second fastener 50 is tightened to fix the base 20 to the first door body 210.

[0092] When the positioning workpiece 30 is positioned using the snap-fit ​​part 35, the first door body 210 is rotated to the second preset angle, or the second door body 310 is rotated to the first preset angle. In other words, the two doors are kept at the same opening angle and brought closer to each other, so that the snap-fit ​​part 35 is snapped into the side surface of the second door body 310, and the positioning device 60 and the second door body 310 are positioned.

[0093] When the positioning workpiece 30 adopts the positioning method of the alignment part 36, the two doors are rotated to bring the first and second doors closer together for alignment. When the alignment surface 361 is aligned with the side surface of the second door 310 and is located on the same plane, it indicates that the positioning device 60 and the second door 310 have completed positioning.

[0094] Tighten the first fastener 40 with a screwdriver. The first fastener 40 is fixed to the second door body 310 along the axial direction of the receiving groove 331. The mounting rib 113 of the receiving groove 331 can play a limiting role. When the head of the first fastener 40 touches the bottom surface of the recessed groove 110, the first fastener 40 is installed in place. In this way, the sliding member 10 is fixed to the second door body 310 with the help of the positioning workpiece 30.

[0095] Operating the separable part 61 to separate the positioning workpiece 30 from the base 20, and to separate the positioning workpiece 30 from the sliding member 10, specifically includes:

[0096] Finally, the positioning workpiece 30 must be detached from the base 20 and the sliding member 10. The positioning workpiece 30 is rotated continuously with force until the separable part 61 is broken off, thus separating the base 20 from the positioning workpiece 30; the positioning connection between the mounting plate 31 and the sliding member 10 is released, thus separating the sliding member 10 from the positioning workpiece 30, allowing the positioning workpiece 30 to be removed.

[0097] For aesthetic purposes, the cover portion 13 of the sliding member 10 is rotated and covers the recessed groove 110, thereby covering the first fastener 40 and the mounting hole 111 therein; the sliding connection device 100 also includes a base cover 23, which can be integrally formed with the base 20. During assembly, the base cover 23 and the base 20 are further separated to prevent the base cover 23 from being lost. Then, the base cover 23 is assembled to the outer periphery of the base 20 to cover the entire base 20, serving an aesthetic and decorative purpose; the base cover 33 and the base 20 can also be formed independently of each other.

[0098] Both the cover portion 13 and the base cover 23 are provided with notches to facilitate operation by staff, so as to meet the needs of opening the cover portion 13 or the base cover 23 later.

[0099] The beneficial effects of this application are as follows: the base 20 and the positioning workpiece 30 are integrally formed, and after positioning with the second door body 310, the positioning workpiece is further removed. The integral forming design reduces the error caused by manual assembly positioning. The sliding part 10 and the positioning workpiece 30 are pre-assembled and fixed by the first and second positioning structures, which improves the positioning accuracy.
