[0027] Please refer to Figure 1-8 , the present invention provides a self-calibrating and anti-wearing 3D rocker structure, including a fixed base 1. In the middle of the top of the fixed base 1, a rocker housing 4 is fixedly installed. On the top of the rocker housing 4, an assembly board 5 is fixedly installed. Inside the rocker housing 4, a rocker assembly 7 is installed. On both sides of the rocker housing 4, suspension assemblies 3 are fixedly installed. Each of the two suspension assemblies 3 includes a suspension frame 31 and two connecting platforms 33. At both ends of one side of the suspension frame 31, first telescopic rods 32 are fixedly installed. The fixed ends of the two first telescopic rods 32 are respectively fixedly connected to one side of the two connecting platforms 33. The rocker assembly 7 includes two length rods 71 and two sliding plates 73. In the middle of the two length rods 71, two displacement blocks 72 are slidably connected. One side of the four displacement blocks 72 is respectively fixedly connected to both sides of the two sliding plates 73. At the top between the two sliding plates 73, a mounting shaft 75 is provided. In the middle of the mounting shaft 75, a direction housing 76 is fixedly installed. On the top of the direction housing 76, a rocker head 78 is provided. Inside the rocker head 78, a displacement sensor 79 is fixedly installed.

[0028] On the surfaces of the two connecting platforms 33, connecting springs 34 are fixedly installed. The ends of the two connecting springs 34 away from the connecting platforms 33 are respectively fixedly connected to the side of the suspension frame 31 facing each other. The sides of the two connecting platforms 33 away from the first telescopic rods 32 are fixedly connected to the rocker housing 4. The user pulls through the suspension frame 31 to complete the handling and transfer of the rocker housing 4.

[0029] Two sliding gears 74 are fixedly installed on the installation shaft 75 on both sides of the direction housing 76. A number of teeth fixedly arranged at the top ends of two sliding plates 73 are respectively meshed and connected with the outer sides of the two sliding gears 74. The displacement block 72 slides along the length rod 71 to adjust the lateral distance of the rocker head 78. While the sliding gear 74 rotates, it contacts the teeth on the sliding plate 73, completing the adjustment of the lateral distance of the rocker head 78. The direction housing 76 rotates to adjust the angle of the rocker head 78, and the displacement sensor 79 accurately detects and senses the position of the rocker head 78.

[0030] Both ends of the two length rods 71 are fixedly connected to one side of the rocker housing 4 facing each other. The rocker assembly 7 is installed on the rocker housing 4 through the length rods 71.

[0031] A height member 77 is fixedly installed at the top end of the direction housing 76. The top end of the height member 77 is connected to the bottom end of the rocker head 78. The height member 77 includes a positioning housing 771 and a driven bevel gear 775. A lifting groove 773 is opened at the top end of the positioning housing 771. A positioning plate 774 is fixedly installed inside the lifting groove 773. A lead screw 772 extending to the outside is threadedly connected inside the positioning plate 774. The bottom end of the positioning plate 774 is rotatably connected to the top end of the driven bevel gear 775. One side of the inner wall of the lifting groove 773 is rotatably connected to a driving bevel gear 776. A handle 777 is fixedly installed in the middle of the driving bevel gear 776. The outer side of the driving bevel gear 776 is meshed and connected with the outer side of the driven bevel gear 775. The bottom end of the positioning housing 771 is fixedly connected to the direction housing 76. The top end of the lead screw 772 is connected to the rocker head 78. When the user rotates the handle 777, the handle 777 drives the driving bevel gear 776 to rotate. The driving bevel gear 776 contacts the driven bevel gear 775. The thread inside the driven bevel gear 775 matches the thread on the surface of the lead screw 772. Therefore, the lead screw 772 rotates and lifts relative to the positioning plate 774 to adjust the use height of the rocker head 78.

[0032] A rubber sleeve 6 is sleeved at the connection between the assembly plate 5 and the rocker assembly 7. The rubber sleeve 6 is made of rubber material, and the rubber sleeve 6 seals the connection between the assembly plate 5 and the rocker assembly 7.

[0033] Threaded holes 2 are opened at the four corners of the top end of the fixed base 1. Screws pass through the threaded holes 2 to complete the fixation of the fixed base 1.

[0034] Two symmetrically arranged anti-slip components 8 are fixedly installed on the surface of the rocker housing 4. Both anti-slip components 8 include a limit plate 81 and two second telescopic rods 82. The two sides of the bottom end of the limit plate 81 are fixedly connected to the fixed ends of the two second telescopic rods 82 respectively. An anti-slip platform 85 is provided at the bottom end of the limit plate 81. A silica gel pad 86 is fixedly installed at the bottom end of the anti-slip platform 85. The movable ends of the two second telescopic rods 82 are fixedly connected to the two sides of the top end of the anti-slip platform 85 respectively. A mounting seat 84 is fixedly installed in the middle of the top end of the anti-slip platform 85. A screw rod 83 that is threadedly connected to the limit plate 81 is rotatably connected to the top end of the mounting seat 84. One side of each of the two limit plates 81 is fixedly connected to the rocker housing 4. When the user rotates the screw rod 83, the thread on the surface of the screw rod 83 matches the thread on the inner wall of the limit plate 81. Therefore, the screw rod 83 rotates and lifts relative to the limit plate 81. The screw rod 83 pushes the mounting seat 84 from the top to adjust the height of the anti-slip platform 85, so that the silica gel pad 86 contacts the installation part of the rocker housing 4. The silica gel pad 86 is made of silica gel material, and the silica gel pad 86 has a large self-friction coefficient, which increases the installation stability of the rocker housing 4.

[0035] When the embodiment of the present application is in use: The user rotates the handle 777, and the handle 777 drives the active umbrella-shaped bevel gear 776 to rotate. The active umbrella-shaped bevel gear 776 contacts the driven umbrella-shaped bevel gear 775. The thread on the inner wall of the driven umbrella-shaped bevel gear 775 matches the thread on the surface of the lead screw 772. Therefore, the lead screw 772 rotates and lifts relative to the positioning plate 774 to adjust the use height of the rocker head 78. The displacement block 72 slides along the length rod 71 to adjust the horizontal distance of the rocker head 78. While the sliding gear 74 rotates, it contacts the teeth on the sliding plate 73, completing the adjustment of the horizontal distance of the rocker head 78. The direction housing 76 rotates to adjust the angle of the rocker head 78. The displacement sensor 79 accurately detects and senses the position of the rocker head 78. When it needs to be carried, the user pulls it through the suspension bracket 31 to complete the handling and transfer of the rocker housing 4. The user rotates the screw rod 83, and the thread on the surface of the screw rod 83 matches the thread on the inner wall of the limit plate 81. Therefore, the screw rod 83 rotates and lifts relative to the limit plate 81. The screw rod 83 pushes the mounting seat 84 from the top to adjust the height of the anti-slip platform 85, so that the silica gel pad 86 contacts the installation part of the rocker housing 4. The silica gel pad 86 is made of silica gel material, and the silica gel pad 86 has a large self-friction coefficient, which increases the installation stability of the rocker housing 4.
