[0050] First aspect

[0051] like Figures 1-9As shown, an embodiment of the present invention provides a connecting device 100, which 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 passes through in the vertical direction Z and is used to connect to the top or bottom of the cabinet door 300. The connecting plate 11 is provided with a first connecting hole 111 that passes through in 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 passes through in the vertical direction and is used to connect to the top or bottom of the cabinet body 200. The connecting seat 2 is provided with a second connecting hole 231 that passes through in 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 provided in 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 that pass through in 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 connector 1 is installed on the top or bottom of the cabinet door 300 through the first mounting hole 112, and the connecting base 2 is installed on the top or bottom of the cabinet body 200 through the second mounting hole 211, the connector 1 can be rotated horizontally around the rotating shaft 3 to drive the cabinet door 300 to rotate horizontally. The rotating shaft 3 moves horizontally 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 at 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 takes up less space; at the same time, by installing the connecting device 100 at the top and / or bottom of the cabinet door 300, it can also avoid the connecting device 100 from 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 use of the cabinet door 300, and having a simple structure.

[0055] In this embodiment, there are two first mounting holes 112 .

[0056] In some other embodiments, the number of the first mounting holes 112 may 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 Figure 1-Figure 5 The connecting member 1 also includes a limiting plate 13, which is connected to one side of the connecting plate 11 and is located at the connection position between the connecting member 1 and the connecting seat 2. The limiting 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 arcuate transition piece 12, through which the limiting piece 13 is connected to the connecting piece 11. The use of the arcuate transition piece 12 allows for a natural transition between the limiting piece 13 and the connecting piece 11 at the connection position, reduces stress concentration at the connection position between the limiting piece 13 and the connecting piece 11, and helps to increase the service life of the connecting device 100. Moreover, this design of connecting the connecting piece 11 and the limiting piece 13 respectively via the arcuate transition piece 12 allows the limiting piece 13 to be bent and formed onto the connecting piece 11 through a bending process. This design is easy to process, offers a variety of colors to choose from, and facilitates installation of the cabinet 200. It has low requirements for product processing technology and greatly reduces product cost.

[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 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 Figure 1-Figure 3 ,and Figure 6-Figure 8The connecting base 2 includes a mounting plate 21, a first tilting portion 22, and a connecting plate 23. A 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 the 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. A 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 base 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 rotational connection between the connecting base 2 and the connecting member 1. The assembly groove 221 can play a guiding and positioning role during the assembly process of the connecting member 1, the rotating shaft 3, and the connecting base 2, thereby facilitating quick and convenient assembly of the three.

[0067] The depth of the assembly groove 221 is b, satisfying the following relationship: a<b. By limiting the relationship between the thickness a of the connecting piece 11 and the depth b of the assembly groove 221 to a<b, an adjustable vertical distance can be provided for the cabinet door 300 during the process of hingedly connecting the cabinet door 300 to the cabinet body 200 via the connecting device 100, thereby helping 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 the end of the mounting plate 21 away from the first tilting portion 22. The cover plate 25 is connected to the 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 body 200. During 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; during 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 created 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 scratches on 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. Using 1.8 mm ≤ b ≤ 2.2 mm allows the depth of the assembly groove 221 to meet the vertically adjustable distance of the standard cabinet door 300 .

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

[0072] The connecting plate 23 includes 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. The end of the first side wall 232 away from the arcuate transition side wall is connected to the first tilting portion 22, and the 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 achieve a natural transition between the first side wall 232 and the second side wall 234 at the connection point, reducing stress concentration at the connection point between the first side wall 232 and the second side wall 234.

[0073] The limiting sidewall 236 is affixed to the limiting plate 13 and is capable of limiting the connection member 1 from rotating about the central axis of the rotation axis 3 in the first direction S. The limiting plate 13 and the limiting sidewall 236 can limit the horizontal rotation angle of the connection member 1 about the rotation axis 3, thereby limiting the rotation angle of the cabinet door 300, achieving accurate control of the maximum opening angle of the cabinet door 300, preventing the cabinet door 300 from colliding with the wall or other cabinet bodies 200, and meeting customer needs.

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

[0075] In some other embodiments, 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 close to 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 between the guide side wall 237 and 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 closer 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 from continuing 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 also 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 closing.

[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. 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 sidewall 236 is a planar structure, and the guiding sidewall 237 is a planar structure. The connection between the limiting sidewall 236 and the guiding sidewall 237 is rounded. The use of the rounded corners allows for a natural transition between the limiting sidewall 236 and the guiding sidewall 237 at the connection point, reduces stress concentration at the connection point between the limiting sidewall 236 and the guiding sidewall 237, and helps to increase 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, which is concentric with the first mounting hole 112, can achieve a natural transition between the second side wall 234 and the limiting side wall 236 at the connection position, reducing stress concentration at the connection position between the second side wall 234 and the limiting side wall 236. Furthermore, the arc side wall 235 can guide or avoid the rotation of the connector 1, thereby preventing interference from occurring at parts of the connector 1 other than the limiting side wall 236 during rotation. This ensures that during the opening process of the cabinet door 300, the connecting plate 23 can only limit the relative rotation between the connector 1 and the connecting seat 2 through the limiting side wall 236, thereby limiting the rotation angle of the cabinet door 300. Furthermore, the maximum opening angle of the cabinet door 300 can be more accurately defined by the connecting device 100.

[0081] By limiting the angle to 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 embodiments, the arc side wall 235 can contact the limiting piece 13 when the connecting piece 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 piece 13 when the connecting piece 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 planar, the second side wall 234 is planar, and the third side wall 238 is planar. The connection between the third side wall 238 and the guide side wall 237 is rounded. The rounded corners create a natural transition between the third side wall 238 and the guide side wall 237 at the connection point, reducing stress concentration at the connection point between the third side wall 238 and the guide side wall 237 and thereby increasing the service life of the connecting device 100.

[0086] The connection base 2 has a first wire hole 212 extending vertically therethrough, and the shaft 3 has a second wire hole 311 extending vertically therethrough. If the cabinet door has a power cord, the power cord can be passed through the connection device 100 through the first and second wire holes 212 and 311, facilitating the routing of the power cord.

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

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

[0089] See Figure 9 The rotating shaft 3 includes a shaft body 31 and a retaining ring 32. The retaining ring 32 is sleeved and fixed to the outer wall of the shaft body 31, with at least a portion of the retaining ring 32 located within the first connecting hole 111. The wall of the second connecting hole 231 is rotatably connected to the shaft body 31 and located on one side of the retaining ring 32. The retaining ring 32 is provided on the shaft body 31 to provide support and positioning during the assembly of the connecting base 2 to the rotating shaft 3 of the connector 1, thereby facilitating quick and convenient assembly of the connecting base 2 and the connector 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 part 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 making the rotation of the cabinet door 300 smoother when the cabinet door 300 is opened for operation.

[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, so as 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 vertical size of the connecting device 100, making the structure of the connecting device 100 more compact, and providing adjustment space for the assembly between the connecting seat 2, the rotating shaft 3 and the connecting member 1.

[0092] Second aspect

[0093] See Figures 10-16 The present invention also provides a cabinet, which includes the connecting device 100 of any one of the above items, and also includes a cabinet door 300 and a cabinet body 200, the connecting piece 11 is connected to the top of the cabinet door 300 and / or the bottom of the cabinet door 300, and the connecting seat 2 is connected to the top of the cabinet body 200 and / or the bottom of the cabinet door 300.

[0094] The cabinet body 200 has a first side 201 and a first front 202, the first side 201 and the first front 202 being connected, and a screw hole 203 for cooperating with the second mounting hole 211 is provided on the top and / or bottom of the cabinet body 200; wherein the thickness of the cabinet door 300 is h, the distance between the connecting base 2 and the first side 201 is d, and the distance between the center of the screw hole 203 and the first front 202 is e, satisfying the following:

[0095] 16mm≤h≤22mm; 3.5mm≤d≤4.5mm, 10mm≤e≤11mm. When the thickness of the cabinet door 300 satisfies 16mm≤h≤22mm, the following restrictions are imposed: 3.5mm≤d≤4.5mm, 10mm≤e≤11mm, to avoid interference and friction between the edge of the cabinet door 300 and the side panel of the cabinet body 200.

[0096] The cabinet door 300 has a second side 301 and a second front 302, which are connected to each other. The distance f between the rotating shaft 3 and the second side 301 is defined as "f," and the distance g between the rotating shaft 3 and the second front 302 is defined as "g," satisfying the following conditions: 5mm≤f≤6mm, 9mm≤g≤10mm. By limiting the distances to 5mm≤f≤6mm and 9mm≤g≤10mm, the opening angle of the cabinet door 300 can be better controlled, preventing the cabinet door 300 from colliding with the cabinet body 200 due to excessive opening angles.

[0097] The installation process of the connecting device 100 provided by the present invention is as follows: fix the connecting piece 11 to the top and / or bottom of the cabinet door 300 by using a first screw, then assemble the connecting seat 2 to the rotating shaft 3 of the limiting piece 13, and pass the second screw through the second mounting hole 211 of the connecting plate 23 and the screw hole 203 of the cabinet body 200. According to the actual thickness of the cabinet door 300, the gap distance between the cabinet door 300 and the cabinet body 200 is adjusted to a suitable range, and the limit angle of the cabinet door 300 is appropriate. Then, tighten the second screw to fix the connecting seat 2 to the cabinet body 200, and then cover the decorative cover 4 on the connecting seat 2.

[0098] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
