[0025] This embodiment describes a three-axis adjustment bracket, which is a simple, stable and reliable universal bracket that can adjust six degrees of freedom.

[0026] As Figures 1 to 3As shown in the figure, the adjusting bracket includes a base 1, a lower bracket 2, a first shaft 3, a second shaft 4, a connecting frame 5, a third shaft 6, and an upper bracket 7. The lower bracket 2 is mounted on the base 1 through the first shaft 3. The upper and lower ends of the connecting frame 5 are connected to the upper bracket 7 and the lower bracket 2 through the third shaft 6 and the second shaft 4 respectively. The first shaft 3, the second shaft 4, and the third shaft 6 are perpendicular to each other, and all can adopt rotatable shaft structures such as rotating shafts or locking bolts. In this embodiment, the locking bolt is taken as an example for illustration.

[0027] Fixing holes 1.1 are respectively provided at the four corners of the base 1. The fixing holes 1.1 are through holes that penetrate up and down, and are used to fix the base 1. A first shaft lower connection hole 1.2 is provided in the middle of the base 1 along the Z-axis direction. In this embodiment, the first shaft lower connection hole 1.2 is a threaded hole, and the internal thread of the threaded hole matches the external thread of the first shaft 3.

[0028] The lower bracket 2 is composed of a base 2.1 and a first support frame 2.3.

[0029] On the base 2.1, there is a first shaft upper connection hole 2.2 that corresponds coaxially to the first shaft connection hole 1.2. Fine tooth rings 8 that are coaxial with the first shaft lower connection hole 1.2 and the first shaft upper connection hole 2.2 are respectively installed on the bottom surface of the base 2.1 and the upper surface of the base 1. In this embodiment, the first shaft upper connection hole 2.2 is a through hole. The first shaft 3 passes through the first shaft upper connection hole 2.2 and screws into the first shaft lower connection hole 1.2 to lock the lower bracket 2 to the base 1. At the same time, the upper and lower fine tooth rings 8 are engaged and connected, which can prevent the locking force from decreasing and ensure that the lower bracket 2 does not displace relative to the base 1 during use. When the first shaft 3 is loosened from the lock, the lower bracket 2 rotates relative to the base 1 around the Z-axis, and then the lower bracket 2 and the components installed thereon rotate a predetermined angle relative to the base 1.

[0030] The first support frame 2.3 is fixed above one side of the base 2.1, and its center is located on the central axis of the base 2.1. A second shaft connection hole 2.4 is provided at the upper end of the first support frame 2.3 along the Y-axis direction. The second shaft 4 passes through the second shaft connection hole 2.4 and is connected to the connecting frame 5. Fine tooth rings 8 that are coaxial with the second shaft connection hole 2.4 are installed on the mating surface between the first support frame 2.3 and the connecting frame 5 for engaging and connecting with the fine tooth rings 8 on the connecting frame 5. The first support frame 2.3 is also connected to the base 2.1 through strengthening blocks 2.5 on each side to enhance the stability of the first support frame 2.3.

[0031] Upper shaft holes 5.1 and lower shaft holes 5.2 are respectively provided at the upper and lower ends of the connecting frame 5, and the axial directions of the upper shaft holes 5.1 and the lower shaft holes 5.2 are perpendicular to each other and are both through holes. In this embodiment, the lower shaft hole 5.2 is arranged along the Y-axis direction, the upper shaft hole 5.1 is arranged along the X-axis direction, and fine tooth rings 8 that are coaxial with the upper shaft hole 5.1 and the lower shaft hole 5.2 are respectively installed on the mounting surfaces at the upper and lower ends of the connecting frame 5.

[0032] The lower shaft hole 5.2 corresponds coaxially to the second shaft connection hole 2.4. The second shaft 4 passes through the second shaft connection hole 2.4 and the lower shaft hole 5.2 and locks the first support frame 2.3 and the connection frame 5 with a nut. The opposing fine-tooth rings 8 engage with each other. When the lock of the second shaft 4 is released, the opposing fine-tooth rings 8 disengage, and the connection frame 5 can rotate relative to the first support frame 2.3 about the Y-axis.

[0033] The upper support frame 7 includes a mounting plate 7.1, mounting holes 7.2, a second support frame 7.3, and a third shaft connection hole 7.4. A plurality of mounting holes 7.2 are provided on the mounting plate 7.1 for mounting the equipment to be supported by the adjustable support. The mounting holes 7.2 are long slot holes and can adjust the mounting position of the equipment within a certain range. The second support frame 7.3 is mounted in the middle of the bottom surface of the mounting plate 7.1. The third shaft connection hole 7.4 is provided on the second support frame 7.3 along the X-axis direction. The third shaft connection hole 7.4 is coaxially opposite to the upper shaft hole 5.1, and a fine-tooth ring 8 coaxial with the third shaft connection hole 7.4 is mounted on the mating surface of the second support frame 7.3 with the connection frame 5. The third shaft 6 passes through the third shaft connection hole 7.4 and the upper shaft hole 5.1 and locks the upper support frame 7 and the connection frame 5 with a nut. The opposing fine-tooth rings 8 engage with each other. When the lock of the third shaft 6 is released, the engagement of the opposing fine-tooth rings 8 is disengaged, and the upper support frame 7 can rotate relative to the connection frame 5 about the X-axis.

[0034] The fine-tooth ring 8 of this embodiment can be integrally cast with the base 1, the lower support frame 2, the connection frame 5, the upper support frame 7, etc. respectively to reduce the production cost.

[0035] When this adjustable support is in use, first fix it at a predetermined position by bolts through the fixing holes 1.1, and then fix the equipment to be supported on the upper support frame 7 with bolts. When the equipment needs to be adjusted by a corresponding angle, loosen the lock of the corresponding first shaft 3, second shaft 4 or third shaft 6, rotate by a corresponding angle around the Z-axis, Y-axis or X-axis, and then lock the shaft after the adjustment is completed, so as to complete the adjustment of the degrees of freedom of the equipment. When the first shaft 3, second shaft 4 and third shaft 6 are locked, the mutual engagement of the fine-tooth rings 8 is utilized to ensure that there will be no displacement in any direction during the use process, which is stable and reliable. In addition, according to the width of the fine teeth on the fine-tooth ring 8, the rotation angle of rotating by the width of one fine tooth can be determined, and thus the rotation angle can be quickly determined according to the number of rotated fine teeth.

[0036] Although the principle of the present invention has been described in detail above in conjunction with the preferred embodiments of the present invention, those skilled in the art should understand that the above embodiments are only explanations of the illustrative implementation modes of the present invention and do not limit the scope of the present invention. The details in the embodiments do not constitute a limitation on the scope of the present invention.
