[0050] First aspect

[0051] like Figure 1-Figure 9As shown, a connecting device 100 provided in an embodiment of the present invention includes a connecting member 1, a connecting seat 2 and a rotating shaft 3.

[0052] The connecting member 1 is used to connect to the top or bottom of the cabinet door 300, and the connecting seat 2 is used to connect to the top or bottom of the cabinet body 200. One end of the connecting member 1 is connected to one end of the connecting seat 2 through a rotating shaft 3 so that the connecting member 1 can rotate horizontally around the rotating shaft 3.

[0053] Specifically, the connecting member 1 includes a connecting plate 11, which is provided with a first mounting hole 112 that penetrates along the vertical direction Z and is used to connect to the top or bottom of the cabinet door 300, and the connecting plate 11 is provided with a first connecting hole 111 that penetrates along the vertical direction and is located on one side of the first mounting hole 112; the connecting seat 2 is provided with a second mounting hole 211 that penetrates along the vertical direction and is used to connect to the top or bottom of the cabinet body 200, and the connecting seat 2 is provided with a second connecting hole 231 that penetrates along the vertical direction, and the second connecting hole 231 is located between the first mounting hole 112 and the second mounting hole 211; the rotating shaft 3 is penetrated through the first connecting hole 111 and the second connecting hole 231 in the vertical direction, the connecting seat 2 is connected to the rotating shaft 3, and the connecting member 1 is connected to the rotating shaft 3 and can rotate around the central axis of the rotating shaft 3.

[0054] Based on this technical solution, by setting the first mounting hole 112, the first connecting hole 111, the second mounting hole 211 and the second connecting hole 231 penetrating along the vertical direction Z, and passing the rotating shaft 3 through the first connecting hole 111 and the second connecting hole 231, the central axis of the first mounting hole 112, the central axis of the second mounting hole 211 and the central axis of the rotating shaft 3 can be made parallel, so that after the connecting member 1 is installed on the top or bottom of the cabinet door 300 through the first mounting hole 112, and the connecting seat 2 is installed on the top or bottom of the cabinet body 200 through the second mounting hole 211, the connecting member 1 can drive the cabinet door 300 by horizontal rotation around the rotating shaft 3. Horizontal movement is performed around the rotating shaft 3 to realize the opening or closing of the cabinet door 300 relative to the cabinet body 200; that is, the connecting device 100 provided by the present invention can be installed on the top and / or bottom of the cabinet to realize the hinge between the cabinet door 300 and the cabinet body 200, which will not increase the thickness of the cabinet door 300 and the cabinet body 200 and occupy less space; at the same time, by installing the connecting device 100 on the top and / or bottom of the cabinet door 300, it is also possible to avoid the connecting device 100 interfering with the rotation of the cabinet door 300 on the inner or outer side of the cabinet door 300, thereby helping the cabinet door 300 to obtain a larger opening angle, improving the convenience of using the cabinet door 300, and having a simple structure.

[0055] In this embodiment, the number of the first mounting holes 112 is two.

[0056] In some other embodiments, the number of the first mounting holes 112 may also be one, three, four, or any other number, which is not limited here.

[0057] In this embodiment, the number of the second mounting holes 211 is two.

[0058] In some other embodiments, the number of the second mounting holes 211 may be one, three, four, or any other number, which is not limited here.

[0059] See also Figure 1-Figure 5 The connecting member 1 also includes a limit plate 13, which is connected to one side of the connecting plate 11 and is located at the connecting position between the connecting member 1 and the connecting seat 2. The limit plate 13 is used to limit the horizontal rotation angle of the connecting member 1 around the rotating shaft 3 to limit the opening angle of the cabinet door 300.

[0060] The connector 1 also includes an arc-shaped transition piece 12, and the limiting piece 13 is connected to the connecting piece 11 through the arc-shaped transition piece 12. The arc-shaped transition piece 12 can realize the natural transition between the limiting piece 13 and the connecting piece 11 at the connection position, reduce the stress concentration at the connection position of the limiting piece 13 and the connecting piece 11, and help to improve the service life of the connecting device 100. Moreover, this design of connecting the connecting piece 11 and the limiting piece 13 respectively through the arc-shaped transition piece 12 can bend the limiting piece 13 to the connecting piece 11 through a bending process, which is easy to process, has a variety of colors to choose from, is easy to install the cabinet 200, has low requirements on product processing technology, and greatly reduces product costs.

[0061] Along the vertical direction, the thickness of the connecting piece 11 is a.

[0062] The thickness direction of the limiting piece 13 intersects with the thickness direction of the connecting piece 11 .

[0063] In this embodiment, the thickness direction of the limiting piece 13 is perpendicular to the thickness direction of the connecting piece 11 .

[0064] In this embodiment, the first mounting hole 112 is a circular mounting hole.

[0065] See also Figure 2 When the connecting device 100 is in the first state, the cabinet is in the open state; Figure 3 When the connecting device 100 is in the second state, the cabinet is in a closed state.

[0066] See also Figure 1-Figure 3 ,and Figure 6-Figure 8The connecting seat 2 includes a mounting plate 21, a first tilting portion 22 and a connecting plate 23. The second mounting hole 211 is provided on the mounting plate 21. One end of the first tilting portion 22 is connected to the mounting plate 21. The connecting plate 23 is connected to one end of the first tilting portion 22 away from the mounting plate 21 and is located on one side of the connecting piece 11 in the vertical direction. The second connecting hole 231 is provided on the connecting plate 23. An assembly groove 221 is formed between the first tilting portion 22 and the connecting plate 23. In this way, the mounting plate 21 can be connected to the top of the cabinet 200 through the second mounting hole 211 to realize the connection between the connecting seat 2 and the cabinet 200, and the connecting plate 23 can be connected to the rotating shaft 3 through the second connecting hole 231 to realize the rotation connection between the connecting seat 2 and the connecting member 1. The assembly groove 221 can play a guiding and positioning role in the assembly process of the connecting member 1, the rotating shaft 3 and the connecting seat 2, so as to facilitate the quick and convenient assembly between the three.

[0067] The groove depth of the assembly groove 221 is b, which satisfies: a<b. By limiting the relationship between the thickness a of the connecting piece 11 and the groove depth b of the assembly groove 221 to be a<b, an adjustable distance can be provided for the cabinet door 300 in the process of hingedly connecting the cabinet door 300 to the cabinet body 200 through the connecting device 100, which helps to improve the installation flatness between the cabinet door 300 and the cabinet body 200.

[0068] In this embodiment, the second mounting hole 211 is a waist-shaped mounting hole. When the connecting base 2 is fixed to the top or bottom of the cabinet 200 by screws, the gap between the cabinet door 300 and the cabinet 200 can be adjusted by adjusting the front and rear position of the second adjusting connecting device 100.

[0069] The connecting seat 2 also includes a second tilting portion 24 and a cover plate 25. The second tilting portion 24 is connected to one end of the mounting plate 21 away from the first tilting portion 22. The cover plate 25 is connected to one end of the second tilting portion 24 away from the mounting plate 21. An avoidance groove 241 is formed between the second tilting portion 24 and the cover plate 25. The avoidance groove 241 is used to avoid the wall of the cabinet 200. In the process of installing the connecting device 100 on the cabinet, it is necessary to adjust the position of the connecting device 100 on the cabinet to adjust the gap between the cabinet door 300 and the cabinet body 200; in the process of adjusting the position of the connecting device 100 on the cabinet, the mounting plate 21 may scratch the cabinet body 200 and cause scratches on the cabinet body 200; by adopting the second tilting portion 24 and the cover plate 25, a gap can be provided between the cover plate 25 and the cabinet body 200 to avoid the cover plate 25 directly contacting the cabinet body 200, and at the same time, the scratches on the cabinet body 200 that may be caused by the scratches of the mounting plate 21 can be hidden by the cover plate 25, thereby maintaining the beauty of the cabinet body 200.

[0070] Preferably, 0.8 mm ≤ a ≤ 2 mm, and 1.8 mm ≤ b ≤ 2.2 mm. By adopting 1.8 mm ≤ b ≤ 2.2 mm, the groove depth of the assembly groove 221 can meet the vertical adjustable distance of the standard cabinet door 300 .

[0071] In this embodiment, a=1.5 mm, b=2 mm.

[0072] The connecting plate 23 has a first side wall 232, an arcuate transition side wall 233, a second side wall 234, an arcuate side wall 235, a limiting side wall 236, a guide side wall 237 and a third side wall 238 which are connected in sequence. One end of the first side wall 232 away from the arcuate transition wall is connected to the first tilting portion 22, and one end of the third side wall 238 away from the guide side wall 237 is connected to the first tilting portion 22. The arcuate transition side wall 233 can realize a natural transition between the first side wall 232 and the second side wall 234 at the connection position, thereby reducing stress concentration between the first side wall 232 and the second side wall 234 at the connection position.

[0073] The limiting side wall 236 is attached to the limiting piece 13 and can limit the connection member 1 from rotating around the central axis of the rotation shaft 3 in the first direction S. The limiting piece 13 and the limiting side wall 236 can limit the angle of horizontal rotation of the connection member 1 around the rotation shaft 3, thereby limiting the rotation angle of the cabinet door 300, achieving accurate control of the maximum opening angle of the cabinet door 300, avoiding collision between the cabinet door 300 and the wall or other cabinets 200, and meeting customer needs.

[0074] In this embodiment, the first direction S is a clockwise direction.

[0075] In some other implementations, the first direction S may also be counterclockwise.

[0076] The guide side wall 237 is connected to one end of the limiting side wall 236 near the first tilting portion 22, and a limiting groove 2361 is formed between the guide side wall 237 and the limiting side wall 236. The guide side wall 237 is used to form the limiting groove 2361 with the limiting side wall 236. When the connecting member 1 rotates along the central axis of the rotating shaft 3 in the first direction S to gradually bring the limiting piece 13 close to the limiting side wall 236, the guide side wall 237 guides the limiting piece 13 to ensure that the limiting piece 13 can fit with the limiting side wall 236 at a preset position, thereby ensuring that the limiting side wall 236 can limit the connecting member 1 to continue to rotate along the central axis of the rotating shaft 3 in the first direction S. Rotation, so that the limiting side wall 236 can better limit the relative rotation between the connecting piece 1 and the connecting seat 2, and limit the rotation angle of the cabinet door 300; by setting the limiting groove 2361, the gap distance between the cabinet door 300 and the cabinet body 200 can be better adjusted, so that the gap distance between the cabinet door 300 and the cabinet body 200 is within a suitable range, thereby avoiding interference between the cabinet door 300 and the cabinet body 200 during the rotation process and taking into account the tightness between the cabinet door 300 and the cabinet body 200 when closed.

[0077] In this embodiment, the plane where the guide side wall 237 is located is perpendicular to the plane where the limiting side wall 236 is located.

[0078] In the description of the present invention, it needs to be understood that the plane where a certain component is located refers to the plane formed by the intersection of the length direction and the width direction of the component. For example, the plane where the guide side wall 237 is located refers to the plane formed by the intersection of the length direction of the guide side wall 237 and the width direction of the guide side wall 237, and the plane where the limiting side wall 236 is located refers to the plane formed by the intersection of the length direction of the limiting side wall 236 and the width direction of the limiting side wall 236.

[0079] In this embodiment, the limiting side wall 236 is a planar structure, and the guiding side wall 237 is a planar structure. The connection position of the limiting side wall 236 and the guiding side wall 237 is a rounded corner setting. The use of the rounded corner setting can achieve a natural transition between the limiting side wall 236 and the guiding side wall 237 at the connection position, reduce the stress concentration at the connection position of the limiting side wall 236 and the guiding side wall 237, and help to improve the service life of the connecting device 100.

[0080] The center of the first mounting hole 112 coincides with the center of the arc side wall 235. The arc side wall 235 concentric with the first mounting hole 112 can realize the natural transition between the second side wall 234 and the limiting side wall 236 at the connection position, reduce the stress concentration of the second side wall 234 and the limiting side wall 236 at the connection position, and can also guide or avoid the rotation of the connecting member 1 through the arc side wall 235 to avoid interference with the parts of the connecting member 1 other than the limiting side wall 236 during the rotation process, thereby ensuring that during the opening process of the cabinet door 300, the connecting plate 23 can only limit the relative rotation between the connecting member 1 and the connecting seat 2 through the limiting side wall 236, limit the rotation angle of the cabinet door 300, and then the maximum opening angle of the cabinet door 300 can be more accurately limited through the connecting device 100.

[0081] By limiting 20°≤j≤50°, the force distribution of the connecting device 100 during use can be improved, the stress of the connecting device 100 during use can be reduced, and the service life of the connecting device 100 can be extended; the material consumption of the connecting plate 23 can be reduced, the production cost of the connecting seat 2 can be reduced, and energy conservation and environmental protection can be achieved.

[0082] In this embodiment, j=45°.

[0083] In some of the embodiments, the arc side wall 235 may contact the limiting plate 13 when the connecting plate 11 rotates around the central axis of the rotating shaft 3 , so that the arc side wall 235 can guide the rotation of the connecting member 1 .

[0084] In some other embodiments, the arc side wall 235 always maintains a gap with the limiting plate 13 when the connecting plate 11 rotates around the central axis of the rotating shaft 3, so that the arc side wall 235 can avoid the rotation of the connecting member 1.

[0085] In this embodiment, the first side wall 232 is a planar structure, the second side wall 234 is a planar structure, and the third side wall 238 is a planar structure; the connection position of the third side wall 238 and the guide side wall 237 is a rounded corner setting. The use of the rounded corner setting can achieve a natural transition between the third side wall 238 and the guide side wall 237 at the connection position, reduce the stress concentration at the connection position of the third side wall 238 and the guide side wall 237, and help to increase the service life of the connection device 100.

[0086] The connection base 2 is provided with a first wire hole 212 penetrating in the vertical direction, and the rotating shaft 3 is provided with a second wire hole 311 penetrating in the vertical direction. When the cabinet door has a power cord, the power cord can be passed through the connection device 100 through the first wire hole 212 and the second wire hole 311, which is convenient for the wiring arrangement of the power cord.

[0087] In this embodiment, specifically, the first wire passing hole 212 is opened on the mounting plate 21 .

[0088] The connection device 100 further comprises a decorative cover 4, which covers the connection base 2. The decorative cover 4 can cover the power line on the connection base 100, thereby preventing leakage caused by the power line being exposed.

[0089] See also Fig. 9 The rotating shaft 3 includes a shaft body 31 and a stop ring 32. The stop ring 32 is sleeved and fixed on the outer wall of the shaft body 31. At least part of the stop ring 32 is located in the first connecting hole 111. The hole wall of the second connecting hole 231 is rotatably connected to the shaft body 31 and is located on one side of the stop ring 32. The stop ring 32 is arranged on the shaft body 31. The stop ring 32 can play a supporting and positioning role in the process of assembling the connecting seat 2 to the rotating shaft 3 of the connecting member 1, so as to facilitate the quick and convenient assembly of the connecting seat 2 and the connecting member 1.

[0090] By setting a limiting ring 32 on the outer wall of the shaft body 31 and limiting a<b, the connecting seat 2 can better cooperate with the connecting member 1 and the rotating shaft 3 to work, reducing the friction between the bottom of the connecting plate 23 and the limiting ring 32 of the rotating shaft 3 (or the top of the connecting plate 11), and when the cabinet door 300 is opened for operation, the rotation of the cabinet door 300 can be smoother.

[0091] By arranging at least part of the limiting ring 32 in the first connecting hole 111, the limiting ring 32 can be used to create a gap between the bottom of the connecting plate 23 and the top of the connecting piece 11 to reduce or even avoid direct contact between the connecting plate 23 and the connecting piece 11, thereby reducing or even eliminating the friction between the connecting plate 23 and the connecting piece 11 during the relative movement between the connecting member 1 and the connecting seat 2, and reducing the size of the connecting device 100 in the vertical direction, making the structure of the connecting device 100 more compact, and providing adjustment space for the assembly of the connecting seat 2, the rotating shaft 3 and the connecting member 1.
