[0001] The invention relates to the technical field of mechanical engineering, and in particular to an angle adjustment component for a tablet computer. Background Art

[0002] With the popularity and development of tablet computers and mobile devices, users have higher and higher requirements for user experience. Especially when tablet computers need to be used for a long time for work, study or entertainment, a support device that can adjust the angle is particularly important. There are still many defects in the angle adjustment assembly during actual use. For example, the existing angle adjustment assembly mostly adopts a metal shaft or hinge connection in the rotation adjustment mechanism. These metal parts are prone to metal fatigue due to frequent opening and closing, which leads to a decrease in the support for the tablet computer. The stability and safety of the device will also be reduced. This not only affects the user experience, but may also cause damage to the tablet computer. Therefore, it is necessary to design an angle adjustment assembly for a tablet computer. Summary of the invention

[0005] With the above technical scheme, the rotating rod is driven to rotate by twisting it, and due to the meshing between the driving rack and the force-bearing rack, the two sets of limit rods in the limit seat can be synchronously driven to slide in relative directions in the limit groove, and the limit rod can be limited by the limit bar to ensure that the limit rod does not tilt, thereby ensuring that the second limit plate is moved horizontally. Since the second limit plate is sleeved on the surface of the third bidirectional threaded rod by the second limit hole, the third mounting sleeve is supported by synchronously adjusting the horizontal position of the second limit plate, and the placement frame can be fixed after the user adjusts the angle according to his or her needs, thereby avoiding metal fatigue causing the device to reduce the supporting force of the tablet, thereby achieving the convenience of angle adjustment and the stability after fixation, thereby ensuring that the user can use the tablet computer safely and comfortably.

[0006] As a further improvement of the above solution, a movable seat is fixedly installed inside the clamping seat, a first toothed disc is arranged around the movable seat, the movable seat matches the rotating shaft, and the first toothed disc matches the second toothed disc.

[0007] Through the above technical solution, the first gear disc arranged around the movable seat and the second gear disc at the bottom of the movable seat can provide appropriate resistance when adjusting the horizontal rotating component, effectively preventing the horizontal rotating component from rotating at will, and facilitating the stable adjustment of the tablet computer by the angle adjustment component.

Since the driving rack and the force rack are engaged, the two sets of limit rods in the limit seat can be synchronously driven to slide in relative directions in the limit groove. The limit rod can be limited by the limit bar to ensure that the limit rod will not tilt and the second limit plate can be moved horizontally.

[0015] As a further improvement of the above scheme, a second limiting plate is fixedly installed at the bottom of the limiting rod, and a second limiting hole is opened inside the second limiting plate. The second limiting hole matches the first bidirectional threaded rod, the second bidirectional threaded rod, and the third bidirectional threaded rod.

[0016] Through the above technical solution, since the second limiting plate is sleeved on the surface of the third bidirectional threaded rod using the second limiting hole, the third mounting sleeve can be supported by synchronously adjusting the horizontal position of the second limiting plate to prevent the clamping assembly from shaking again.

[0017] As a further improvement of the above scheme, the number of the limit assemblies is set to five, with limit assemblies set on both sides of the first bidirectional threaded rod, limit assemblies set on both sides of the second bidirectional threaded rod, and limit assemblies set on both sides of the third bidirectional threaded rod.

[0018] Through the above technical solution, the third mounting sleeve is supported by synchronously adjusting the horizontal position of the second limit plate, and at the same time, since the limit components are fixedly installed on both sides of the first bidirectional threaded rod and the second bidirectional threaded rod, the first support frame, the second support frame and the clamping assembly can be fixed by twisting the rotating rod after the user adjusts the angle according to his or her needs, thereby achieving the convenience of angle adjustment and stability after fixation, ensuring that the user can use the tablet computer safely and comfortably, and avoiding the reduction of the device's supporting force on the tablet computer due to metal fatigue.

The convenience of angle adjustment and the stability after fixation are achieved, thereby ensuring that the user can use the tablet computer safely and comfortably.

[0026] The first gear disc 107 arranged around the movable seat 106 and the second gear disc 204 at the bottom of the movable seat 201 can provide appropriate resistance when adjusting the horizontal rotating component 2, effectively preventing the horizontal rotating component 2 from rotating randomly, and facilitating the stable adjustment of the tablet computer by the angle adjustment component 3.

[0027] The outer surface of the first movable rod 302 is sleeved with a first mounting sleeve 304, and a first support frame 305 is fixedly installed on one end of the first mounting sleeve 304 away from the first movable rod 302. A second mounting sleeve 306 is fixedly installed on one end of the first support frame 305 away from the first mounting sleeve 304. The interior of the second mounting sleeve 306 is sleeved with a second mounting seat 307, and the interior of the second movable rod 308 is fixedly installed on the interior of the second mounting seat 307.

[0028] A second bidirectional threaded rod 309 is fixedly installed inside the second movable rod 308 , a second support frame 310 is fixedly installed on one end of the second mounting seat 307 away from the second mounting sleeve 306 , and a third mounting sleeve 311 is fixedly installed on one end of the second support frame 310 away from the second mounting sleeve 306 .

[0029] By sleeved the first mounting sleeve 304 on the first movable rod 302, the first support frame 305 will be rotated and adjusted with the first mounting seat 301 as the center, the second mounting sleeve 306 is sleeved on the outer surface of the second movable rod 308, the second support frame 310 will be adjusted with the second mounting seat 307 as the center, the third mounting sleeve 311 is sleeved on the surface of the third movable rod 403, and the connecting plate 401 will be adjusted with the third mounting seat 402 as the center, which can facilitate users to adjust the angle of the device according to their needs.

[0030] A third mounting seat 402 is fixedly installed at the rear end of the connecting plate 401, a third movable rod 403 is fixedly installed inside the third mounting seat 402, a third bidirectional threaded rod 404 is fixedly installed inside the third movable rod 403, a third mounting sleeve 311 is sleeved on the surface of the third movable rod 403, and the connecting plate 401 and the placement rack 406 are threadedly connected via a limiting screw 405.

[0031] The placement rack 406 can be installed on the front end of the connecting plate 401 by screwing the limiting screw 405 , and the placement rack 406 can also be disassembled at the same time, so that the user can replace the fixture according to their needs.

[0032] A rotating rod 502 is rotatably installed on the top of the limit seat 501, and a driving rack 503 is arranged at the bottom of the rotating rod 502. A limiting groove 504 is opened inside the limit seat 501, and a limiting rod 505 is slidably installed inside the limiting groove 504. A limiting bar 506 matching the limit seat 501 is arranged on one side of the limit rod 505, and a force-bearing rack 507 meshing with the driving rack 503 is arranged on the other side of the limit rod 505.

[0033] When the clamping is completed, the rotating rod 502 is driven to rotate in the limit assembly 5 by twisting. Since the driving rack 503 is meshed with the force rack 507, the two sets of limit rods 505 in the limit seat 501 can be synchronously driven to slide in relative directions in the limit groove 504. The limit rod 505 can be limited by the limit bar 506 to ensure that the limit rod 505 will not tilt and the second limit plate 508 can be moved horizontally.

[0034] A second limiting plate 508 is fixedly installed at the bottom of the limiting rod 505 . A second limiting hole 509 is opened inside the second limiting plate 508 . The second limiting hole 509 matches the first bidirectional threaded rod 303 , the second bidirectional threaded rod 309 , and the third bidirectional threaded rod 404 .

[0035] Since the second limiting plate 508 is sleeved on the surface of the third bidirectional threaded rod 404 using the second limiting hole 509 , the third mounting sleeve 311 can be supported by synchronously adjusting the horizontal position of the second limiting plate 508 to prevent the clamping assembly 4 from shaking.

[0036] There are five limit assemblies 5 . Limit assemblies 5 are set on both sides of the first bidirectional threaded rod 303 , limit assemblies 5 are set on both sides of the second bidirectional threaded rod 309 , and limit assemblies 5 are set on both sides of the third bidirectional threaded rod 404 .

[0037] By synchronously adjusting the horizontal position of the second limit plate 508, the third mounting sleeve 311 is held in place. At the same time, since the limit components 5 are fixedly installed on both sides of the first bidirectional threaded rod 303 and the second bidirectional threaded rod 309, the first support frame 305, the second support frame 310 and the clamping component 4 can be fixed by twisting the rotating rod 502 after the user adjusts the angle according to his or her needs, thereby achieving the convenience of angle adjustment and stability after fixation, ensuring that the user can use the tablet computer safely and comfortably, and avoiding metal fatigue that causes the device to reduce the supporting force of the tablet.

[0038] The implementation principle of an angle adjustment component for a tablet computer in the embodiment of the present application is as follows: by clamping the clamping seat 101 at the desired installation position and twisting the turntable 104, the limiting threaded rod 103 will be lifted and lowered by using the thread on the surface of the first limiting hole 102. When the first limiting plate 105 rises to a suitable position, the installation processing of the installation component 1 can be completed. Since a rotating groove 202 is provided at the bottom of the movable seat 201, the movable seat 201 can be conveniently installed on the top of the movable seat 106, and the rotating shaft 203 can be used to rotate and adjust the horizontal rotation component 2. The first toothed disc 107 arranged around the movable seat 106 and the second toothed disc 204 at the bottom of the movable seat 201 can be used. When adjusting the horizontal rotation component 2, appropriate resistance is provided to effectively prevent the horizontal rotation component 2 from rotating randomly, and the angle adjustment component 3 is convenient for the stable adjustment of the tablet computer. By sleeve-fitting the first mounting sleeve 304 on the first movable rod 302, the first support frame 305 will be rotated and adjusted with the first mounting seat 301 as the center of the circle, the second mounting sleeve 306 is sleeved on the outer surface of the second movable rod 308, the second support frame 310 will be adjusted with the second mounting seat 307 as the center of the circle, the third mounting sleeve 311 is sleeved on the surface of the third movable rod 403, and the connecting plate 401 will be adjusted with the third mounting seat 402 as the center of the circle, which can facilitate users to adjust the angle of the device according to their needs; By pulling the telescopic rod 407, the tablet computer is placed on the surface of the support plate 408, and the placement frame 406 can support the tablet computer. By rotating the flip plate 409 to limit the tablet computer, the tablet computer can be prevented from sliding. By screwing the limit screw 405, the placement frame 406 can be installed on the front end of the connecting plate 401. At the same time, the placement frame 406 can also be disassembled, which is convenient for users to replace the clamp according to their needs. When the clamping is completed, it is driven to rotate in the limit assembly 5 by screwing the rotating rod 502. Due to the meshing between the driving rack 503 and the force-bearing rack 507, the two sets of limit rods 505 in the limit seat 501 can be synchronously driven to slide in relative directions in the limit groove 504. The limit bar 506 can be used to limit the limit rod 505 to ensure that the limit rod 5 05 will not tilt, ensuring that the second limit plate 508 can move horizontally. Since the second limit plate 508 is sleeved on the surface of the third two-way threaded rod 404 using the second limit hole 509, the third mounting sleeve 311 can be supported by synchronously adjusting the horizontal position of the second limit plate 508 to prevent the clamping assembly 4 from shaking. At the same time, since the limit assembly 5 is fixedly installed on both sides of the first two-way threaded rod 303 and the second two-way threaded rod 309, the first support frame 305, the second support frame 310 and the clamping assembly 4 can be fixed by twisting the rotating rod 502 after the user adjusts the angle according to his or her needs, thereby achieving the convenience of angle adjustment and the stability after fixation, ensuring that the user can use the tablet computer safely and comfortably, and avoiding metal fatigue causing the device to reduce the supporting force of the tablet.
