[0038] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] See also Figures 1 to 13As shown, the present invention provides an angle adjustment device 100, which includes: a fixed component 10, including a fixed seat 11; a rotating component 20, including a rotating connection part 21 and a rotating structure 22 installed on the rotating connection part 21, the rotating connection part 21 is constructed to be connected to the structure to be rotated, and the rotating connection part 21 is rotatably connected to the fixed seat 11; and an adjustment component 30, including a first eccentric structure 31, the first eccentric structure 31 is rotatably connected to the fixed seat 11, and the first eccentric structure 31 is constructed to be able to cooperate with the rotating structure 22 to enable the rotating connection part 21 to rotate relative to the fixed seat 11.

[0040] In this embodiment, the fixed seat 11 is fixedly mounted on the structure to be installed (such as a table leg 81), and the rotating connection part 21 is used to connect with the structure to be rotated (such as a table top 80). When the angle of the structure to be rotated needs to be adjusted, the first eccentric structure 31 is rotated relative to the fixed seat 11. The first eccentric structure 31 cooperates with the rotating structure 22 to drive the rotating connection part 21 relative to the fixed seat 11. Since the rotating connection part 21 is connected to the structure to be rotated, it can drive the structure to be rotated to rotate and achieve angle adjustment. Compared with the traditional device that uses a fixed gear or a gear-type mechanical structure to adjust the angle of the desktop, the present application allows the structure to be rotated (such as a table top 80) to be continuously and steplessly adjusted within a certain range through the cooperation of the first eccentric structure 31 and the rotating structure 22. The continuous rotation of the first eccentric structure 31 ensures that the table top 80 can be adjusted to any angle, rather than just a few preset fixed positions, thereby enhancing the applicability of the device.

[0041] It should be noted that the angle adjustment device 100 of the present application is easy to adjust, and even the weight of the table top load can be adjusted. At the same time, it has the advantages of small shaking gap, easy installation, low process requirements, and low price.

[0042] See also Figures 1 to 13 As shown, in one embodiment of the present invention, the fixing assembly 10 further includes a fixing member 32, which is mounted on the fixing seat 11. The fixing member 32 is arranged corresponding to the rotating structure 22. The inner circumference of the fixing member 32 is provided with a first ring gear structure 321, and the outer circumference of the rotating structure 22 is provided with a second ring gear structure 221. Part of the second ring gear structure 221 is engaged with the first ring gear structure 321, and the first eccentric structure 31 can drive the rotating structure 22 to perform eccentric movement.

[0043] In this embodiment, the first gear ring structure 321 includes a plurality of first teeth arranged circumferentially along the inner circumference of the fixed member 32, and the second gear ring structure 221 includes a plurality of second teeth arranged circumferentially along the outer circumference of the rotating member. The rotating structure 22 is fixedly mounted on the rotating connection portion 21. When the first eccentric structure 31 rotates, it drives the rotating structure 22 to perform eccentric motion, causing a portion of the second gear ring structure 221 disposed on the outer circumference of the rotating structure 22 to engage with the first gear ring structure 321, that is, a portion of the first teeth and a portion of the second teeth engage, allowing the second gear ring structure 221 to move along the edge of the first gear ring structure 321. Compared to traditional gear adjustment or continuous sliding adjustment, the present application achieves angular adjustment in smaller steps through the coordination of the plurality of first teeth and the plurality of second teeth. The plurality of first teeth forming the first gear ring structure 321 and the plurality of second teeth forming the second gear ring structure 221 are both arranged continuously, allowing the rotating structure 22 to be adjusted in smaller angular increments, thereby achieving stepless adjustment.

[0044] In addition, when the structure to be rotated (such as the table top 80) is adjusted to the desired angle, the first eccentric structure 31 stops rotating. At this time, the second ring gear structure 221 on the rotating structure 22 engages with the first ring gear structure 321 on the fixing member 32 to lock the table top 80 in the current position. This locking mechanism utilizes the self-locking characteristics of the tooth structure, that is, when the first eccentric structure 31 does not continue to rotate, the second ring gear structure 221 is still engaged with the first ring gear structure 321 to prevent the rotating structure 22 from rotating in the opposite direction, thereby ensuring that the table top 80 will not accidentally change its angle due to external force during use, thereby improving the stability and reliability of the adjustment component 30.

[0045] In one embodiment, the fixing member 32 is a circular ring structure, the first gear ring structure 321 is provided on the inner circumference of the fixing member 32 , and the rotating structure 22 is a disc structure, the second gear ring structure 221 is provided on the outer circumference thereof.

[0046] See also Figures 1 to 13 As shown, in one embodiment of the present invention, the angle adjustment device 100 also includes a rotating handle 40, the first eccentric structure 31 includes a first connecting structure 313 and a first eccentric cone 312, the first connecting structure 313 is connected to the first eccentric cone 312, the first connecting structure 313 is constructed to be connected to the rotating handle 40, the central axis of the first connecting structure 313 is collinear with the central axis of the rotating handle 40, the central axis of the first eccentric cone 312 is not collinear with the central axis of the first connecting structure 313, and a first through hole 222 is further provided on the rotating structure 22, the first eccentric cone 312 is penetrated into the first through hole 222 and adapted to the first through hole 222.

[0047] In this embodiment, the first connecting structure 313 is connected to the rotating handle 40, and the user can rotate the first eccentric structure 31 by rotating the rotating handle 40. The central axis of the first connecting structure 313 is collinear with the central axis of the rotating handle 40, so that when the user rotates the rotating handle 40, the first connecting structure 313 can rotate synchronously with the rotating handle 40.

[0048] When the angle of the rotating structure (such as the table top 80) needs to be adjusted, the user starts to rotate the rotating handle 40. Since the central axis of the first connecting structure 313 is collinear with the central axis of the rotating handle 40, the rotation of the rotating handle 40 will be directly transmitted to the first connecting structure 313, so that the first connecting structure 313 also rotates synchronously with the rotating handle 40. Since the first eccentric cone 312 is offset relative to the geometric center of the first connecting structure 313, when the first connecting structure 313 rotates, the first eccentric cone 312 will perform eccentric motion in the first through hole 222 and push the second ring gear structure 221 on the rotating structure 22 to move along the edge of the first ring gear structure 321 of the fixed part 32. This is continuous and not restricted by any fixed gear position. That is, as the first eccentric cone 312 rotates, the position of the second ring gear structure 221 on the first ring gear structure 321 will also change continuously, thereby driving the continuous change of the angle of the structure to be rotated (such as the table top 80), thereby realizing stepless adjustment of the angle of the structure to be rotated (such as the table top 80).

[0049] In addition, when the structure to be rotated (such as the table top 80) is adjusted to the desired angle, the user stops rotating the rotating handle 40. At this time, the first eccentric cone 312 stops the eccentric movement, and the position of the second ring gear structure 221 on the first ring gear structure 321 is fixed. Due to the self-locking characteristics of the tooth structure, the second ring gear structure 221 always remains engaged with the first ring gear structure 321, which can prevent the structure to be rotated (such as the table top 80) from moving in the opposite direction or shaking, and ensure that the angle adjustment of the structure to be rotated (such as the table top 80) under load will not cause shaking or instability.

[0050] See also Figures 1 to 13 As shown, in one embodiment of the present invention, the first eccentric structure 31 also includes a first auxiliary connection structure 311, which is arranged on the first eccentric cone 312, and the central axis of the first connection structure 313 is collinear with the central axis of the first auxiliary connection structure 311, and the first connection structure 313 and the first auxiliary connection structure 311 are located on opposite sides of the first eccentric cone 312, the first auxiliary connection structure 311 is rotatably connected to the fixed seat 11, and a second through hole 111 is provided on the fixed seat 11, and the first auxiliary connection structure 311 is passed through the second through hole 111 and adapted to the second through hole 111.

[0051] In the embodiment, since the central axis of the first connecting structure 313 is collinear with the central axis of the first auxiliary connecting structure 311, the user can rotate the rotary handle 40 more smoothly, and the rotation connection between the first auxiliary connecting structure 311 and the fixed seat 11 makes the entire first eccentric structure 31 (including the first eccentric circular table 312, the first connecting structure 313 and the first auxiliary connecting structure 311) more stable during use, avoiding shaking during operation and improving the comfort and efficiency of operation.

[0052] With reference to Figures 1 to 13 In an embodiment of the present application, the rotary connecting part 21 includes the second connecting structure 211 and the first rotary part 212 connected with the second connecting structure 211, the second connecting structure 211 is configured to be connected with the structure to be rotated, the fixed seat 11 includes the first fixed part 112, the first rotary part 212 is arranged corresponding to the first fixed part 112, the rotary structure 22 is installed on the first rotary part 212, the fixing part 32 is installed on the first fixed part 112, and the rotary structure 22 and the fixing part 32 are located between the first rotary part 212 and the first fixed part 112.

[0053] In the embodiment, the first rotary part 212 provides installation space for the installation of the rotary structure 22, and the first fixed part 112 provides installation space for the installation of the fixing part 32. Through the above arrangement, the installation of the first rotary part 212 and the first fixed part 112 can be realized, and the overall structure can be more compact, and the space utilization can be improved.

[0054] With reference to Figures 1 to 13 In an embodiment of the present application, the first rotary part 212 is provided with a third through hole 2121, the second through hole 111 is arranged on the first fixed part 112, the third through hole 2121 is arranged corresponding to the first through hole 222, and the center of the first through hole 222 is not collinear with the center of the second through hole 111, and the first eccentric circular table 312 is sequentially arranged through the third through hole 2121 and the first through hole 222.

[0055] In the embodiment, when the first eccentric circular table 312 is rotated under the driving of the rotary handle 40, the offset of the first eccentric circular table 312 relative to the central axes of the third through hole 2121 and the first through hole 222 can make the second gear ring structure 221 on the rotary structure 22 move along the edge of the first gear ring structure 321 of the fixing part 32, realizing stepless adjustment of the angle. The center of the first through hole 222 is not collinear with the center of the second through hole 111, so as to ensure that the first auxiliary connecting structure 311 can be arranged through the second through hole 111.

[0057] In the present embodiment, the first rotating part 212 is rotatably connected with the first fixed part 112 through the first eccentric structure 31, the second rotating part 213 is rotatably connected with the second fixed part 113 through the second eccentric structure 50, and the two fixed parts are arranged along the first direction in a spaced manner, which can jointly form a more stable support structure. The double eccentric connection design can disperse the force received by the to-be-rotated structure at different angles and reduce the load borne by a single eccentric structure, thereby enhancing the structural stability and durability of the entire angle adjusting device 100.

[0059] Through the above arrangement, the synchronous rotation of the first rotating part 212 and the second rotating part 213 can be realized, and the structural stability of the angle adjusting device 100 is improved.

[0084] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: a fixed component, a rotating component and an adjusting component are provided, and when the angle of the structure to be rotated needs to be adjusted, the first eccentric structure is rotated relative to the fixed seat, and the first eccentric structure cooperates with the rotating structure to drive the rotating connection part relative to the fixed seat. Since the rotating connection part is connected to the structure to be rotated, it can drive the structure to be rotated to rotate and achieve angle adjustment. Compared with the traditional device that uses a fixed gear or a gear-type mechanical structure to adjust the angle of the desktop, the present application allows the structure to be rotated (such as a table top) to be continuously and steplessly adjusted within a certain range through the cooperation of the first eccentric structure and the rotating structure. The continuous rotation of the first eccentric structure ensures that the structure to be rotated (such as a table top) can be adjusted to any angle, rather than just a few preset fixed positions, thereby enhancing the applicability of the device.
