[0037] Reference Figure 1 , an embodiment of the utility model provides a sliding connection device 100, referring to Figure 5 In one embodiment of the utility model, a household appliance device 1000 is provided. The household appliance device 1000 includes a built-in household appliance 200, such as a refrigerator, and a cabinet 300 for accommodating the built-in household appliance 200. The household appliance 200 includes a first door body 210 and a box body, and the first door body 210 is used to open or close the box body.

[0038] The cabinet 300 includes a second door body 310, which covers the first door body 210. The sliding connection device 100 is used to slidingly connect the first door body 210 to the second door body 310. When the second door body 310 is opened, the first door body 210 can be driven to open, thereby opening the box of the household appliance 200.

[0039] In one embodiment, combining Figure 2-4As shown, the sliding connection device 100 includes a base 20 for cooperating with the first door body 210 and a sliding member 10 for cooperating with the second door body 310, and the base 20 is slidably connected with the sliding member 10. The sliding member 10 and the base 20 are arranged between the first door body 210 and the second door body 310 to drive the first door body 210 and the second door body 310 to be slidably connected.

[0040] In one embodiment, 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. In this way, 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 and the base 20 slide relative to each other, thereby driving the first door body 210 and the second door body 310 to slide relative to each other.

[0041] In a specific embodiment, the first fastener 40 and the second fastener 50 are both screws, and the first fastener 40 and the second fastener 50 both include a nut and a screw. In a specific embodiment, the size and detailed structure of the first fastener 40 and the second fastener 50 may be different, as long as the function of fixed connection can be achieved by the screw.

[0042] In one embodiment, the sliding member 10 includes a positioning portion 13 for positioning with the second door body 210 and a mounting portion 11 for assembling and fixing with the second door body 210. In this way, the sliding member 10 itself can be positioned and fixedly assembled with the second door body 210, which simplifies positioning, has a simple structure, and is easy to operate.

[0043] In one embodiment, the sliding member 10 includes a connecting structure 16 connecting the positioning portion 13 and the mounting portion 11 . The thickness of the connecting structure 16 is thinner than that of the positioning portion 13 and the mounting portion 11 . The connecting structure 16 is configured to be elastically rotatable.

[0044] The sliding member 10 is a sheet-shaped body, the mounting portion 11, the connecting structure 16 and the positioning portion 13 are arranged in sequence, and the connecting structure is configured to be rotatable, so that the positioning portion 13 can rotate relative to the mounting portion 11 after completing the positioning function to cover part of the mounting portion 11 and act as a cover. Here, after the elastic rotation, the mounting portion 11 is still in a connected state with the positioning portion 13.

[0045] In other embodiments, the connection structure 16 is configured to be breakable, and can be broken after elastic rotation, so that the positioning portion 13 and the mounting portion 11 are in a separated state. The positioning portion 13 and the mounting portion 11 are separable through the connection structure 16. When the sliding member 10 is assembled, the connection structure 16 is operated, the positioning portion 13 is separated from the mounting portion 11, and then the positioning portion 13 covers a part of the surface of the mounting portion 11.

[0046] The mounting portion 11 is used to be installed and fixed on the second door body 310, so the mounting portion 11 is provided with a first mounting hole 111 that cooperates with the first fastener 40. After installation, in order to have a better appearance, the positioning portion 13 is used to cover the first fastener 40 and the first mounting hole 111.

[0047] The two long sides of the mounting portion 11 are formed as sliding portions 12 for sliding in the sliding groove 220 of the base 20. The positioning portion 13 is connected to one short side of the mounting portion 11. A recessed groove 110 for accommodating the positioning portion 13 is provided on the surface of the mounting portion 11.

[0048] The size of the recessed groove 110 is adapted to the positioning portion 13 , and the positioning portion 13 is used to cover the recessed groove 110 and act as a cover. It can be understood that the recessed groove 110 does not penetrate the sliding member 10 .

[0049] The first mounting hole 111 is further arranged in the recessed groove 110. It can be understood that the first mounting hole 111 is arranged to penetrate the sliding member 10 so that the first fastener 40 can pass through for installation, and after the positioning portion 13 cooperates with the recessed groove 110, it just covers the first mounting hole 111 and the first fastener 40 therein.

[0050] In a preferred embodiment, the sliding member 10 further includes a positioning structure 112 disposed in the first mounting hole 111, and the positioning structure 112 is used to pre-position the first fastener 40 in the first mounting hole 111. In this way, the first fastener 40 can be pre-installed on the sliding member 10, and there is no need to wait until the sliding member 10 and the second door body 310 are assembled before installing the first fastener 40. In addition, the first fastener 40 is pre-positioned on the sliding member 10, so it is not easy to be lost, and it will not be confused with other fasteners of similar size and similar structure.

[0051] In a preferred embodiment, the positioning structure 112 includes a positioning rib 113 that is positioned and matched 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. The positioning rib 113 is connected to the inner edge of the mounting hole 112. In this way, the positioning rib 113 can clamp 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 form a circle, so that the inner edge of the positioning rib 113 completely matches the outer periphery of the screw, thereby enhancing the friction force and increasing the strength of the combination of the two.

[0052] In a preferred embodiment, an escape space is formed between the positioning rib 113 and the inner edge of the mounting hole 112 to provide space for elastic deformation of the positioning rib 113 to facilitate the installation of the first fastener 40. The positioning structure 112 includes a connecting rib 114 connecting the positioning rib 113 and the inner edge of the mounting hole.

[0053] The positioning rib 113 is used to pre-position the first fastener 40. When the first fastener 40 begins to be tightened and performs a spiral motion, if the positioning rib 113 is too hard, it will be difficult for the operator to operate it, and the positioning rib 113 is easy to break. After the avoidance space is set, the positioning rib 113 and the first fastener 40 are relatively easy to cooperate with, which is convenient for the operator to install, and the positioning rib 113 is not easy to break, thereby improving the service life of the sliding part 10.

[0054] In one embodiment, the positioning portion 13 includes an alignment mark for aligning with a set position of the second door body 310 , and the sliding member 10 and the second door body 310 are positioned by aligning the alignment mark with the second door body 310 .

[0055] Specifically, the positioning portion 13 includes a bottom wall 131 and side walls 132 located on both sides of the bottom wall 131 along the width direction thereof, and the bottom wall 131 is perpendicular to the side walls 132. The bottom wall 131 is a main body wall, which is mainly used to cover the mounting portion 11. During positioning and assembly, the bottom wall 131 is in a vertical state, thereby being parallel to the inner surface of the second door body 310, and the side walls 132 are in a horizontal state, thereby being perpendicular to the inner surface of the second door body 310.

[0056] The alignment mark includes grooves 133 disposed on both sides of the positioning portion 13 along the width direction thereof, and the grooves 133 are used to align with the side edges of the second door body 310 .

[0057] Each of the side walls 132 forms the groove 133, and the groove 133 includes a first inclined surface, a second inclined surface extending in the opposite direction from the first inclined surface, and an alignment line 134 located between the first inclined surface and the second inclined surface. The first inclined surface and the second inclined surface are planes, and the groove 133 is V-shaped. The first inclined surface and the second inclined surface can also be arc-shaped surfaces, as long as there is an alignment line 134 at the connection transition.

[0058] Combination Figure 8 As shown, the alignment lines 134 are vertical straight lines. When the two alignment lines 134 are aligned with the side edges of the second door body 310, it indicates that the positioning portion 13 is in the best position.

[0059] The alignment mark includes a straight portion 135 disposed on the bottom wall 131, the straight portion 135 is located between the two grooves 133, and the straight portion 135 is located on the same straight line as the alignment line 134. If only the alignment line 134 is provided, the alignment mark is not obvious enough, and there may be errors in human eye observation. Adding the straight portion 135 makes the alignment mark clearer and more obvious, thereby increasing the accuracy of alignment.

[0060] The straight portion 135 may be formed as a protrusion, a groove, or other distinctive marks.

[0061] The positioning portion 13 further includes a barb 136 disposed on the side wall 132, and the barb 136 is used to cooperate with the buckle hole 15 of the sliding member 10. When the positioning portion 13 rotates to act as a cover, the barb 136 is snapped into the buckle hole 15 for buckling and fixing, thereby preventing the positioning portion 13 from falling off.

[0062] In other words, when the sliding member 10 is assembled with the positioning workpiece 30, the snap hole 15 is used to snap-fit ​​with the elastic snap 35 of the positioning workpiece; when the first fastener 40 is tightened and the sliding member 10 is fixed to the second door body 310, the elastic snap 35 must be disengaged from the snap hole 15 so that the positioning workpiece 30 can be removed, so that the snap hole 15 is empty, and when the positioning portion 13 is rotated into the recessed groove 110, the hook portion 136 is snapped into the snap hole 15.

[0063] In one embodiment, the base 20 includes a vertical third mounting plate 21 and a fourth mounting plate 22, the third mounting plate 21 is used to cooperate with the positioning workpiece 30 described below, the fourth mounting plate 22 is parallel to the sliding member 10, and the fourth mounting plate 22 is provided with a sliding groove 220 for the sliding member 10 to slide.

[0064] The base 20 includes a second mounting hole 211 for mounting the second fastener 50 and a limiting structure cooperating with the second fastener 50 to prevent the second fastener 50 from moving and falling off. The second mounting hole 211 and the limiting structure are arranged on the third mounting plate 21. The second fastener 50 is usually pre-installed on the first door body 210, and the base 20 cooperates with the second fastener 50 through the second mounting hole 211, so as to be installed on the first door body 210.

[0065] The limiting structure includes a locking hole 212 connected 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 . The inner diameter of the locking hole 212 is adapted to the outer diameter of the screw of the second fastener 50 .

[0066] When fixing, the base 20 first cooperates with the nut clearance of the second fastener 50 through the second mounting hole 211, so that the base 20 can be inserted between the second fastener 50 and the first door body 210, and then the base 20 is moved so that the screw of the second fastener 50 cooperates 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 to limit the movement of the second fastener 50.

[0067] The sliding connection device 100 includes a positioning workpiece 30, and the sliding member 10, the base 20 and the positioning workpiece 30 are formed separately. In the prior art, the positioning workpiece 30 is usually mainly used to assist the relative position between the sliding member 10 and the second door body 310 to position the sliding member 10 so that the sliding member 10 is fixed at the best position of the second door body 210. In this case, the sliding member 10 can achieve positioning by itself, and the positioning workpiece 30 is only used to cooperate with the sliding member 10 to pre-position the first fastener 40. It can be understood that after the assembly is completed, the positioning workpiece 30 still needs to be further disassembled.

[0068] In one embodiment, a pre-positioning structure is provided between the positioning workpiece 30 and the sliding member 10, and the positioning workpiece 30 is still assembled and matched with the sliding member 10 first to pre-position the position of the first fastener 40, so as to facilitate subsequent fixation. After the positioning workpiece 30 is pre-positioned and assembled with the sliding member 10, the positioning part 13 of the sliding member 10 and the second door body 310 are aligned, and the positioning is accurate, the structure is simple, and the operation is convenient. More preferably, after the positioning workpiece 30 is pre-positioned and assembled with the sliding member 10, they are assembled together with the base 20.

[0069] The positioning workpiece 30 includes a first mounting plate 31 that cooperates with the base 20 and a second mounting plate 32 that cooperates with the sliding member 10. The first mounting plate 31 and the second mounting plate 32 are perpendicular to each other, the first mounting plate 31 cooperates with the third mounting plate 21, and the second mounting plate 32 cooperates with the mounting portion 13.

[0070] In one embodiment, the pre-positioning structure includes a first pre-positioning portion 34 disposed on the second mounting plate 32 and a second pre-positioning portion 14 disposed on the sliding member 10. The first pre-positioning portion 34 is disposed toward the sliding member 10, and the second pre-positioning portion 14 is positioned and matched with the first pre-positioning portion 34. When the positioning workpiece 30 and the sliding member 10 are pre-positioned and assembled, the first fastener 40 should be received in the receiving groove 331.

[0071] In a specific embodiment, the first pre-positioning portion 34 is a positioning column arranged toward the sliding member 10, and the second pre-positioning portion 14 is a positioning hole; or the first pre-positioning portion 34 is a positioning hole, and the second pre-positioning portion 14 is a positioning column arranged toward the positioning workpiece. The pre-positioning structure is provided as a positioning column and a positioning hole that cooperate with each other, which is simple to align and easy to install, and also convenient to pull out the positioning workpiece 30 from the sliding member 10 during subsequent disassembly.

[0072] Specifically, after the positioning workpiece 30 and the sliding member 10 are pre-positioned and assembled, the fixed connection between the two can be strengthened by a snap-on structure. The positioning workpiece 30 is provided with an elastic snap 35 near the first pre-positioning portion 34, and the sliding member 10 is provided with a snap hole 15 that cooperates with the elastic snap 35. The elastic snap 35 is combined with the snap hole 15 to strengthen the stability of the connection between the two.

[0073] The positioning workpiece 30 includes a limiting column 33 disposed on the second mounting plate 32 and opposite to the first mounting hole 111 . The limiting column 33 includes a receiving groove 331 for receiving the first fastener 40 . The first fastener 40 is limited in the receiving groove 331 and cooperates with the first mounting hole 111 .

[0074] The limiting column 33 includes a step portion 332 arranged at one end of the receiving groove 331 away from the first mounting hole 111, and the step portion 332 protrudes inward relative to the inner wall surface of the receiving groove 331. The step portion 332 has a step surface 333 facing the mounting hole, and the distance between the step surface 333 and the first mounting hole 111 is not greater than the length of the first fastener 40; the first fastener 40 has a pre-installed state, in which the nut of the first fastener 40 is limited to the step surface 333 along its axial direction, and the end of the screw is limited to the positioning rib 113.

[0075] Continue to combine Figure 6-8As shown, 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 first mounting hole 111. When the positioning workpiece 30 and the sliding member 10 are further assembled with the second door body 310, shaking may occur. In order to prevent the first fastener 40 from being affected and offset, a step surface 333 is set along the axial direction of the first fastener 40. In this way, the nut of the first fastener 40 is restricted by the step surface 333 along the axial direction, and the end of the screw of the first fastener 40 is also restricted by the positioning rib 113 along the axial direction, and the first fastener 40 as a whole cannot be offset along the axial direction. It should be noted that the axial direction of the first fastener 40 is also the common axial direction of its nut and screw.

[0076] Furthermore, the inner diameter of the receiving groove 331 gradually increases in the direction approaching the first mounting hole 111, and 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 adjacent to the step surface 333.

[0077] Specifically, the step portion 332 protrudes inward relative to the inner wall surface of the receiving groove 331, and the nut of the first fastener 40 is limited to the step surface 333 along the axial direction and is located below the step surface 333. If the inner diameter of the inner wall surface of the receiving groove 331 below the step surface 333 is too large, the nut of the first fastener 40 may be tilted in the radial direction in the case of shaking or vibration. Therefore, the inner diameter of the receiving groove 331 near the step surface 333 is set to be less than or equal to the outer diameter of the nut of the first fastener 40, so that the first fastener 40 can be clamped. Alternatively, the inner diameter of the receiving groove 331 near the step surface 333 is slightly larger than the outer diameter of the nut of the first fastener 40 within 3 mm. Within this deviation range, the radial deviation of the first fastener 40 will not affect the normal installation of the first fastener 40.

[0078] In one embodiment, the limiting column 33 includes an outer peripheral wall 334 that surrounds the receiving groove 331 and a through groove 335 arranged on the outer peripheral wall 334. The through groove 335 penetrates the inner surface and the outer surface of the outer peripheral wall 334 along the radial direction of the limiting column 33, so that the outer peripheral wall 334 includes a plurality of arc walls arranged at intervals along the circumferential direction. The outer peripheral wall 334 has a certain elastic deformation space, which is convenient for the installation of the first fastener 40.

[0079] Combination Figure 6-8 As shown, the present application also provides a method for installing a sliding connection device 100, comprising the following installation steps:

[0080] The base 20 is provided; the base 20 may be fixed to the first door body 210 in advance.

[0081] Specifically, the second fastener 50 is pre-loosened by 5-8 mm. In other embodiments, other values ​​may be used according to different sizes 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 .

[0082] After lifting the second fastener 50 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, and then the base 20 is moved, the locking hole 212 is matched with the second fastener 50, and then the second fastener 50 is tightened to pre-fix the base 20 to the first door body 210.

[0083] The sliding member 10 is provided. The sliding member 10 includes a first mounting hole 111 and a positioning structure 112 disposed in the first mounting hole 111 .

[0084] A first fastener 40 is provided, and the first fastener 40 is pre-positioned at the positioning structure 112 , so that the first fastener 40 is pre-combined with the sliding member 10 .

[0085] A positioning workpiece 30 is provided and assembled with a sliding member 10 pre-installed with a first fastener 40 so that the receiving groove 331 limits the first fastener 40. In this way, the first fastener 40 is limited between the sliding member 10 and the positioning workpiece 30, which is convenient for subsequent fixation.

[0086] It is understandable that the base 20, the sliding member 10, the positioning workpiece 30 and the first fastener 40 are provided in any order. It is understandable that the base 20 is independently fixed to the first door body 210. The base 20 can be fixed to the first door body 210 in advance, and then the sliding member 10 and the positioning workpiece 30 are assembled; or, after the sliding member 10 and the positioning workpiece 30 are assembled, the base 20 is fixed to the first door body 210; in short, the base is fixed to the first door body 210, and is independent of the assembly of the sliding member 10 and the positioning workpiece 30.

[0087] The key point is that the first fastener 40 should be pre-positioned in the positioning structure 112 of the sliding member 10, and then assembled with the positioning workpiece 30. The first pre-positioning portion 34 is positioned and matched with the second pre-positioning portion 14, the elastic buckle 35 is buckled with the buckle hole 15, and the positioning portion 13 passes through the through opening 363; after the positioning workpiece 30 and the sliding member 10 are assembled, 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.

[0088] Next, the sliding member 10 and the positioning workpiece 30 are matched with the base 20 on the first door body 210. Specifically, the first door body 210 and the second door body 310 should be opened to substantially the same angle. The assembled sliding member 10 and the positioning workpiece 30 are matched with the base 20 along the length direction of the first door body 210, wherein the sliding portion 12 of the sliding member 10 slides into the sliding groove 220 of the base 20. After sliding for a distance, the first mounting plate 31 of the positioning workpiece 30 gradually abuts against the third mounting plate 21 of the base 20. At this time, referring to the alignment mark of the positioning portion 13, when the alignment line 134 and the straight portion 135 are aligned and overlapped with the side edge of the second door body 310, it indicates that the positioning workpiece 30 has been installed in place.

[0089] Furthermore, the first fastener 40 is pre-installed in the positioning workpiece 30 and the sliding member 10. The first fastener 40 is tightened 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 contacts 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.

[0090] Finally, the positioning workpiece 30 is to be disassembled from the base 20 and the sliding member 10. The snap connection between the first mounting plate 31 and the third mounting plate 21 is released, the snap connection between the second mounting plate 32 and the sliding member 10 is released, and the first pre-positioning portion 34 and the second pre-positioning portion 14 are pulled out and separated. In this way, the positioning workpiece 30 can be removed relative to the base 20 and the sliding member 10.

[0091] Taking into account the aesthetic effect, the positioning portion 13 of the sliding member 10 is rotated and covered to the recessed groove 110, thereby covering the first fastener 40 and the first mounting hole 111 therein; the sliding connection device 100 also includes a base cover 23, and the base cover 23 and the base 20 can be formed integrally, and the base cover 23 and the base 20 are further separated during assembly to prevent the base cover 23 from being lost, and then the base cover 23 is assembled to the outer periphery of the base 20 to cover the entire base 20, thereby playing a decorative role; the base cover 33 and the base 20 can also be formed independently of each other.

[0092] The positioning portion 13 and the base cover 23 are both provided with notches for easy operation by staff, so as to meet the need of opening the positioning portion 13 or the base cover 23 later.

[0093] An embodiment of the present application further provides a door assembly, which includes the first door body 210 , the second door body 310 and the sliding connection device 100 , and the sliding member 10 and the base 20 slidingly connect the first door body 210 and the second door body 310 .

[0094] Combination Figure 9-12 As shown, the present application also provides another embodiment of a sliding connection device 100, the structure of the base 20 and the positioning workpiece 30 are exactly the same as those of the first embodiment, and will not be repeated here. Most structures of the sliding member 10, such as the mounting portion 11 and the sliding portion 12, are also consistent, except that the sliding member 10 has a positioning portion 13' with a different structure.

[0095] The positioning portion 13 ′ is still connected to the mounting portion 11 via the connecting structure 16 , and the connecting structure 16 is configured to be breakable so that the positioning portion 13 ′ is separated from the mounting portion 11 .

[0096] The positioning portion includes a bottom wall 131 ′ and a pasting wall 136 located on one side of the bottom wall 131 ′ along its length direction. The pasting wall 136 is perpendicular to the bottom wall 131 ′ and is used to pasting and align with the side surface of the second door body 310 .

[0097] In one embodiment, the alignment line 134 and the straight portion 135 are aligned with the side edge of the second door body 310 in a linear overlap manner. In another embodiment, the covering wall 136 is aligned with the side surface of the second door body 310 in a planar covering manner.

[0098] Since the covering wall 136 and the bottom wall 131' are vertically arranged and the length extending relative to the second door body 310 is longer, after assembly, if the positioning portion 13' is directly rotated to cover the mounting portion 11, the covering wall 136 will protrude in front of the mounting portion 11, affecting the appearance and also affecting the normal opening and closing of the first door body 210.

[0099] Therefore, in one embodiment, the sliding connection device 100 includes a cover 60 for covering the recessed groove 110 of the mounting portion 11. Figure 13-16 As shown, the cover body 60 is formed separately, the sliding member 10 and the base 20 have been fixed to the first door body 210 and the second door body 310 respectively, the positioning workpiece 30 is removed, and then the positioning part 13 ′ is removed through the connecting structure 16 , and finally, the cover body 60 is installed in the recessed groove 110 .

[0100] The cover body 60 includes a hook 61 , which has the same function as the barb 136 . When the positioning portion 13 ′ is removed, the buckle hole 15 is vacant. When the cover body 60 is inserted into the recessed groove 110 , the hook 61 is inserted into the buckle hole 15 .
