Description

Technical Field

[0001] This application relates to the technical field of hinges, and particularly to a hinge and a tea table. Background Art

[0002] A hinge, also known as a hinge joint, is often two-folded. It is a component that connects two parts of an object and enables them to move. It is a mechanical device that is often used to connect two solids and allow relative rotation between them.

[0003] Existing tea tables are usually designed with a storage space for storing items and are equipped with a cover for closing the storage space. By connecting the hinge to the inner wall of the tea table and the cover, the cover can be switched between the closed and open states. When the cover is in the open state, people can put items into or take out the stored items from the storage space. When the cover is in the closed state, furniture such as teacups and dinner plates can be placed on the cover.

[0004] However, for the cover supporting the existing tea table, when manually closing the cover, if it is closed too quickly, it may cause the hand to not be withdrawn in time, resulting in being pinched by the cover. At the same time, closing the cover too quickly will also generate a large amount of noise. Finally, when the cover closes, it will contact the tea table, and closing too quickly will cause the cover and the tea table to collide violently, resulting in damage to the cover and the tea table and affecting the service life of the tea table.

The rotating shaft 6 is arranged at the rear end of the rotating member 2, and the rotating member 2 is rotatably connected to the rotating shaft 6 and can rotate around the rotating shaft 6. A limiting shaft 13 is also provided on the fixing member 1. The limiting shaft 13 is located in front of the rotating shaft 6 and is used for limiting when the rotating member 2 is opened relative to the fixing member 1, so as to prevent the rotating member 2 from colliding with the fixing member 1 during rotation, resulting in damage to the hinge.

[0049] A first shaft hole 1121 and a second shaft hole 1122 are provided on the side portion 112.

The avoidance opening 10 includes a first opening 110 provided on the main mounting bracket 11 and a second opening 120 provided on the secondary mounting bracket 12.

[0053] Please refer Figure 1 and Figure 5 、 Figure 8 and Figure 9 As shown, the width of the rotating member 2 is close to that of the fixing member 1. The rotating member 2 includes a first connecting frame 21 and a second connecting frame 22, and the second connecting frame 22 is arranged above the first connecting frame 21.

The sliding shaft 5 is located at the rear end of the rotating member 2, and both ends of the sliding shaft 5 pass through the fifth shaft hole 211 to connect the first connecting frame 21 and the sliding shaft 5. The rotating shaft 6 and the limiting shaft 13 are both located above the sliding shaft 5.

[0055] One end of the second connecting frame 22 is fixed to the rotating shaft 6 and can rotate around the rotating shaft 6 to drive the first connecting frame 21 to rotate. The rotating shaft 6 includes a shaft body 61 and a connecting body 62. The connecting body 62 is sleeved outside the shaft body 61 and can rotate around the shaft body 61. One end of the second connecting frame 22 is connected to the connecting body 62, so that the second connecting frame 22 can rotate around the shaft body 61. The second connecting frame 22 is connected to the shaft body 61 through the connecting body 62. By adjusting the thickness of the connecting body 62, the height between the second connecting frame 22 and the fixing member 1 can be adjusted, so that the second connecting frame 22 can be adapted to the damping members 4 and the control pull rods 3 with different lengths and heights.

[0056] In the embodiment of the present application, the connecting body 62 is a hexahedron, and one surface of the connecting body 62 is connected to the second connecting frame 22 by welding. In other embodiments, the second connecting frame 22 can also be connected to the connecting body 62 by bonding or other means. At the same time, the connecting body 62 can also be in the shape of a tetrahedron, an octahedron, etc., and the present application does not limit this.

[0057] The second connecting bracket 22 is provided with a fifth through hole 226 that cooperates with the fourth through hole 212. A bolt passes through the fourth through hole 212 and the fifth through hole 225 to connect and fix the first connecting bracket 21 and the second connecting bracket 22.

When the rotating member 2 is closed relative to the fixed member 1, the upper plate 224 is parallel to the top surface of the fixed member 1 and is located above the fixed member 1. When the rotating member 2 is opened relative to the fixed member 1, the upper plate 224 flips to the rear of the front side edge of the fixed member 1. The upper plate 224 is provided with a mounting hole 225 for connecting and fixing the upper plate 224 to the furniture component to be rotated.

[0062] Please refer Figure 4 、 Figure 5 and Figure 10 As shown, the middle part of the control pull rod 3 is rotatably connected to the fixed member 1. One end of the control pull rod 3 is rotatably connected to the damper 4. The other end of the control pull rod 3 is provided with a limit groove 30, and the sliding shaft 5 can move in the limit groove 30.

[0063] In the illustrated embodiment, the control pull rod 3 includes a pair of identical pull rod pieces. In other embodiments, the control pull rod 3 can also be an integral structure, and the present application does not limit this.

[0064] A plurality of first bushings 33 are sleeved on the sliding shaft 5. The plurality of first bushings 33 are arranged at intervals to limit the relative position between the sliding shaft 5 and the control pull rod 3, thereby preventing the sliding shaft 5 from jamming when moving in the limit groove 30.

[0065] In an embodiment of the present application, there are three first bushings 33 sleeved on the part of the sliding shaft 5 outside the limiting groove 30. The diameter of the first bushing 33 is greater than the width of the limiting groove 30, and the control pull rod 3 is clamped between the spaced-apart first bushings 33.

[0066] A pull rod shaft 7 is provided between the middle of the control pull rod 3 and the fixing member 1, and the control pull rod 3 can rotate around the pull rod shaft 7. A linkage shaft 8 is provided between the first end of the control pull rod 3 and the damping member 4. The linkage shaft 8 can move as the control pull rod 3 rotates, thereby driving the damping member 4. A plurality of second bushings 36 are sleeved at both ends of the linkage shaft 8 to protect the linkage shaft 8. In an embodiment of the present application, one second bushing 36 is sleeved at each end of the linkage shaft 8.

[0067] Both the first bushing 33 and the second bushing 36 are plastic bushings made of POM (polyoxymethylene). In other embodiments, the first bushing 33 and the second bushing 36 can also be bushings made of other materials such as metals and alloys. The present application does not limit this.

[0068] A sixth shaft hole 34 and a seventh shaft hole 35 are provided on the control pull rod 3. Both ends of the pull rod shaft 7 pass through the sixth shaft hole 34 and the third shaft hole 121, thereby installing the control pull rod 3 on the sub-mounting frame 12. Both ends of the linkage shaft 8 pass through the seventh shaft hole 35, thereby installing the linkage shaft 8 on the control pull rod 3.

[0069] The control pull rod 3 includes a first rod portion 31 and a second rod portion 32 connected to each other. The first rod portion 31 and the second rod portion 32 form an obtuse angle. The second rod portion 32 is located above the first rod portion 31. The limiting groove 30 is provided on the first rod portion 31. The second rod portion 32 is rotatably connected to the damping member 4. The pull rod shaft 7 is provided at the connection between the first rod portion 31 and the second rod portion 32. The first rod portion 31 and the second rod portion 32 can rotate around the pull rod shaft 7. The linkage shaft 8 is provided between the second rod portion 32 and the damping member 4, and the linkage shaft 8 can move as the second rod portion 32 rotates.

[0070] Please refer Figure 2 and Figure 3 As shown, the process of the rotating member 2 opening and closing relative to the fixing member is that the sliding shaft 5 moves from one end of the limiting groove 30 to the other end. The setting of the limiting groove 30 enables the rotating angle of the rotating member 2 to be greater than the rotating angle of the control pull rod 3, thereby reducing the rotating angles of the control link 3 and the damping member 4 and reducing the stroke of the damping member 4.

[0071] The rotating member 2, the control pull rod 3, and the damping member 4 are arranged on the fixing member 1 from front to back. One end of the damping member 4 is rotatably connected to the fixing member 1, and the other end of the damping member 4 is rotatably connected to the linkage shaft 8, thereby rotatably connecting the damping member 4 and the control pull rod 3.

[0072] Please refer Figure 4 andFigure 5 As shown, the damping member 4 is a hydraulic cylinder. The hydraulic cylinder includes a cylinder block 41 and a telescopic arm 42. One end of the cylinder block 41 is rotatably connected to the fixing member 1. The telescopic arm 42 is disposed within the cylinder block 41 and one end thereof is connected to the control pull rod 3 through a linkage shaft 8.

[0073] A connecting shaft 40 is provided between the cylinder block 41 and the fixing member 1. Both ends of the connecting shaft 40 pass through the fourth shaft hole 122 to fix the connecting shaft 40 to the sub-mounting bracket 12. The cylinder block 41 is rotatably connected to the connecting shaft 40 and can rotate around the connecting shaft 40.

[0074] Please refer Figure 2 、 Figure 3 、 Figure 4 As shown, when the rotating member 2 is closed relative to the fixing member 1, the rotating member 2 drives the control pull rod 3 to rotate. The telescopic arm 42 moves together with the linkage shaft 8 and extends relative to the cylinder block 41. The cylinder block 41 rotates around the connecting shaft 40. At this time, the telescopic arm 42 releases resistance during the extension process, so that the rotating member 2 can be slowly closed relative to the fixing member 1, thereby preventing pinching.

[0075] Please refer Figure 12 As shown, the damping member can also be a spring 4'. One end of the spring 4' is sleeved on the connecting shaft 40, and the other end of the spring 4' is sleeved on the linkage shaft 8, so as to be connected to the fixing member 1 and the control pull rod 3. The spring 4' can also be connected to the fixing member 1 and the control pull rod 3 in other ways. For example, if it is not sleeved on the shaft, both ends can be directly fixed to the fixing member 1 and the control pull rod 3. This application does not limit this.

[0076] When the damping member is the spring 4', the principle is the same as that of the hydraulic cylinder. When the rotating member 2 is closed relative to the fixing member 1, the spring 4' is stretched, thereby applying resistance to the rotating member 2.

[0077] For the hinge provided in this application, when the rotating member 2 is closed relative to the fixing member 1, the damping member 4 applies resistance to the rotating member 2 through the control pull rod 3, so that the rotating member 2 can be slowly closed to prevent pinching the human body.

[0078] Please refer Figure 11 As shown, this application also provides a tea table, including: a box body 91, a cover plate 92 and the above hinge. The box body 91 encloses an accommodation cavity, and an opening 911 communicating with the accommodation cavity is provided on the box body 91. The fixing member 1 is fixed to the inner side wall of the box body 91, and the rotating member 2 is fixed to the cover plate 92. When the rotating member 2 rotates, it drives the cover plate 92 to switch between a closed state and an open state. In the closed state, the cover plate 92 covers the opening 911; in the open state, the cover plate 92 is located outside the opening 911.

[0079] The fixing member 1 is arranged at the middle of one edge of the opening 911, and the rotating member 2 is arranged at the middle of the corresponding edge of the cover plate 92. The bolt passes through the first through hole 1111 to fix the main mounting frame 11 to the box body 91, and the main mounting frame 11 is located at the middle of one edge of the opening 911. The bolt also passes through the fifth through hole 225 to fix the upper plate 224 to the cover plate 92, and the upper plate 224 is located at the middle of the cover plate 92.

[0080] The main mounting frame 11 does not block the opening 911. When the rotating member 2 is relative to the fixing member 1 in the open state, the cover plate 92, the upper plate 224 and the connecting plate 223 are all located outside the opening 911, so as to reduce the shielding of the opening 911 by the cover plate 92 and the hinge, thereby allowing objects with a larger area to pass through the opening. The upper plate 224 is located at the middle of the cover plate 92, and the main mounting frame 11 is located at the middle of one edge of the opening 911. Therefore, only one hinge needs to be installed on the cover plate 92 provided in this application to realize the opening and closing of the cover plate 92, thus saving costs. Moreover, the bolts for installing the hinge are all located outside the opening 911, and the bolts are hidden when the cover plate 92 is opened, making the overall tea table more beautiful. The cover plate 92 can be slowly closed when it is closed, so as to prevent pinching, reduce the noise during closing, and avoid violent collision between the cover plate 92 and the box body 91 when closing. The whole is safe and reliable, providing a better user experience.

[0081] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent replacements, improvements, etc. made within the spirit and principle of this application shall be included within the scope of protection of this application.
