DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The embodiment of the present application discloses a rotary adjustment device.

[0023] Reference Figure 1 and Figure 2 The rotary adjustment device includes a mounting frame 1, to which a rotary rod 2 is rotatably connected, and a rotary sleeve 3 is provided on the outer edge of the rotary rod 2. The mechanical component to be adjusted is arranged at the end of the rotary rod 2 away from the rotary sleeve 3, and the mounting frame 1 is provided with a locking structure for locking and fixing the adjusted rotary sleeve 3. Therefore, when the operator rotates the rotary sleeve 3, the rotation of the rotary sleeve 3 drives the rotary rod 2 and the mechanical component to be adjusted to rotate synchronously, thereby adjusting the angle of the mechanical component. After the mechanical component is rotated to the required angle, the position of the rotary sleeve 3 is directly and quickly locked and fixed by the locking mechanism on the mounting frame 1, which greatly reduces the workload of the personnel when debugging the limit of the mechanical component. Its quick locking and adjustment state switching operation is simple and easy, greatly simplifies the operating steps of the operator, and improves the efficiency of adjusting the mechanical component.

[0024] Reference Figure 1 and Figure 2 A pressure block 17 is provided at one end of the rotary rod 2, and the rotary sleeve 3 is tightly pressed between the pressure block 17 and the mounting frame 1. A mounting bolt is passed through the pressure block 17, and a threaded hole 18 matching the size of the mounting bolt is provided on the surface of the rotary rod 2 facing the pressure block 17. The mounting bolt is threaded into the threaded hole 18. Therefore, the operator can remove the pressure block 17 from the rotary rod 2 by removing the bolts, thereby achieving a detachable connection between the pressure block 17 and the rotary rod 2. The pressure block 17 limits the position of the rotary sleeve 3, and the rotary sleeve 3 is tightly pressed between the pressure block 17 and the mounting frame 1, reducing the possibility of the rotary sleeve 3 shifting during the operator's adjustment process and improving the stability of the position of the rotary sleeve 3.

[0025] Reference Figure 1 and Figure 2The outer edge of the rotating rod 2 is provided with a connecting key, and the inner edge of the rotating sleeve 3 is provided with a keyway 16 of a size matching the connecting key. The connecting key is inserted into the keyway 16. The tight fit between the connecting key and the keyway 16 achieves effective torque transmission and effectively prevents the rotating sleeve 3 from rotating relative to the rotating rod 2. The outer edge of the rotating rod 2 is fixedly connected to the stabilizing ring 14. The outer edge of the rotating rod 2 is covered with a gasket 15. The gasket 15 is tightly pressed between the stabilizing ring 14 and the mounting frame 1. The gasket 15 can effectively increase the contact area between the stabilizing ring 14 and the mounting frame 1, eliminating the gap between the stabilizing ring 14 and the mounting frame 1.

[0026] Reference Figure 1 and Figure 2 The locking structure includes two connecting columns 4 arranged on the end face of the mounting frame 1 facing the rotating sleeve 3, and the outer edges of the two connecting columns 4 are respectively rotatably connected to the friction plates 5. The two friction plates 5 are arranged opposite to each other, and the outer edges of the two connecting columns 4 are respectively sleeved with a first shaft sleeve 12 and a second shaft sleeve 13. The friction plate 5 is located between the first shaft sleeve 12 and the second shaft sleeve 13. In the embodiment of the present application, the first shaft sleeve 12 and the second shaft sleeve 13 can be made of rubber material. The first shaft sleeve 12 and the second shaft sleeve 13 limit the position of the friction plate 5, reduce the possibility of axial movement of the friction plate 5, and improve the stability of the position of the friction plate 5.

[0027] Reference Figure 2 、 Figure 3 and Figure 4 The mounting frame 1 is provided with a pushing unit for controlling the contact between the two friction plates 5 and the inner edge of the rotating sleeve 3. The pushing unit comprises a stop block 6 slidably connected to the mounting frame 1. The stop block 6 defines a waist-shaped hole 9. A sliding post 10, sized to match the waist-shaped hole 9, is provided on the end surface of the mounting frame 1 facing the rotating sleeve 3. The sliding post 10 slidably engages within the waist-shaped hole 9. Mounting posts 7 are mounted on each of the friction plates 5. A spring 8 is mounted between the two mounting posts 7. In this embodiment, the spring 8 is a hook spring 8 with compression elasticity, facilitating the return of the two friction plates 5. The stop block 6 has an anti-slip bevel 11 on the surface facing the friction plates 5. The end of the friction plate 5 facing the stop block 6 is curved. When the stop block 6 abuts the two friction plates 5, the curved end of the friction plate 5 abuts against the anti-slip bevel 11. The anti-slip bottom 11 forms a small boss that acts as a stop, reducing the possibility of the friction plates 5 shifting.

[0028] When the cam 10 is in the closed position, the two friction plates 5 are in contact with each other, and the two friction plates 5 are in the closed position.

[0029] When the cam 10 is in the locked position, the two friction plates 5 are in contact with each other, and the two friction plates 5 are in the locked position.

[0030] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
