DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] Example 1: Please refer to Figure 1 - Figure 7 This utility model provides the following technical solution: A machine vision illuminator adjustable at multiple angles, comprising a rotating rod 1 and a base 2, wherein the rotating rod 1 is rotatably connected to the interior of the base 2, and a mounting sleeve 3 is fixedly connected to the top of the rotating rod 1. A universal joint structure is provided in the middle of the rotating rod 1, and the universal joint structure includes an upper mounting seat 21 and a lower mounting seat 22 mounted at both ends inside the rotating rod 1. A cross shaft 23 is rotatably connected between the upper mounting seat 21 and the lower mounting seat 22, and the upper mounting seat 21, the lower mounting seat 22, and the cross shaft 23 form a universal joint. A positioning sleeve 24 is slidably connected to the outside of the lower mounting seat 22, and a positioning threaded sleeve 25 is slidably connected to the outside of the upper mounting seat 21, and the positioning threaded sleeve 25 is rotatably connected to the outside of the positioning sleeve 24. A telescopic structure is provided inside the mounting sleeve 3, and a lateral adjustment structure is installed on the top of the mounting sleeve 3. A groove 4 is provided on one side of the telescopic structure mounting sleeve 3, and a telescopic rod 5 is slidably connected inside the mounting sleeve 3. The lower end of the telescopic rod 5 is threaded with a first self-tightening screw 6, and the end of the first self-tightening screw 6 away from the telescopic rod 5 extends to the outside of the mounting sleeve 3 through the sliding groove 4; the top of the mounting sleeve 3 is mounted with a mounting rod 7 through a universal joint structure, and the mounting rod 7 is rotatably connected with a mounting shaft 8. The mounting rod 7 is threaded with a second self-tightening screw 9 on one side, and the end of the second self-tightening screw 9 inside the mounting rod 7 is in contact with the mounting shaft 8; the top of the mounting shaft 8 is fixedly connected with an arc-shaped mounting bracket 10, and the mounting bracket 10 is rotatably connected with a mounting ring 11. The two ends of the mounting ring 11 are connected to the inside of the mounting bracket 10 through shafts, and a washer 12 is fixedly connected to the outside of one of the shafts; the mounting bracket 10 has a threaded hole 13 inside one end, and the washer 12 is located inside the threaded hole 13. The threaded hole 13 is threaded with a self-tightening sleeve 14, and the end of the self-tightening sleeve 14 inside the threaded hole 13 is in contact with the washer 12.

[0028] During the use of the device, the base 2, mounting sleeve 3, telescopic rod 5, mounting rod 7, and support rod 15 form a bracket. By rotating the first self-tightening screw 6, it is separated from the slide groove 4. At this time, the first self-tightening screw 6 will lose its restraining effect on the telescopic rod 5, thereby adjusting the position of the telescopic rod 5 inside the mounting sleeve 3. When the telescopic rod 5 is adjusted to a suitable height, the first self-tightening screw 6 is rotated to make it fit against the slide groove 4, thereby adjusting the position of the telescopic rod 5 inside the mounting sleeve 3, and thus adjusting the overall height of the bracket.

[0029] When the second self-tapping screw 9 is rotated to separate the end thereof from the mounting shaft 8, the mounting shaft 8 can be rotated inside the mounting rod 7, thereby adjusting the angle of the support rod 15 in the horizontal direction. When the angle of the support rod 15 in the horizontal direction is adjusted, the second self-tapping screw 9 is rotated to attach the end thereof to the mounting shaft 8, thereby fixing the angle of the support rod 15 in the horizontal direction.

[0030] When the self-tapping screw 14 is rotated inside the threaded hole 13 until the self-tapping screw 14 and the washer 12 are separated from each other, the shafts at both ends of the mounting ring 11 can be rotated at both ends of the mounting frame 10, thereby adjusting the rotation angle of the support rod 15 in the vertical direction inside the mounting ring 11. When the angle of the support rod 15 is adjusted, the self-tapping screw 14 is rotated to clamp the washer 12 on both sides inside the threaded hole 13 by the self-tapping screw 14, thereby fixing the washer 12 inside the threaded hole 13, fixing the position of the mounting ring 11 inside the mounting frame 10, and fixing the rotation angle of the support rod 15 in the vertical direction.

[0031] The middle of the rotating rod 1 and the connection between the mounting sleeve 3 and the mounting rod 7 are provided with a universal joint structure. When the positioning sleeve 24 and the positioning threaded sleeve 25 are connected to each other, the positioning threaded sleeve 25 and the positioning sleeve 24 form an integral whole, wrapping the upper mounting seat 21, the lower mounting seat 22, and the cross shaft 23 constituting the universal joint, thereby preventing the upper mounting seat 21, the lower mounting seat 22, and the cross shaft 23 from moving. At this time, the rotating rod 1 and the connection between the mounting sleeve 3 and the mounting rod 7 are perpendicular. When the positioning threaded sleeve 25 and the positioning sleeve 24 are separated from each other, the universal joint formed by the upper mounting seat 21, the lower mounting seat 22, and the cross shaft 23 will play its role, allowing the middle of the rotating rod 1 and the connection between the mounting sleeve 3 and the mounting rod 7 to rotate in any direction.

[0032] When the support rod 15 and the movable shooting device are connected to each other, the first self-tapping screw 6 and the sliding groove 4 can be separated, the telescopic rod 5 can move inside the mounting sleeve 3, thereby allowing the support to move vertically along the movable shooting device. At the same time, the third self-tapping screw 16 and the support rod 15 are separated from each other, allowing the support to move horizontally along the mechanical energy of the shooting device. When the universal joint structure is in the open state as shown in the figure, the rotating rod 1 and the connection between the mounting sleeve 3 and the mounting rod 7 can rotate in any direction, thereby allowing the support to move irregularly with the shooting device.

[0034] The third self-tapping screw 16 and the slot at the top of the supporting rod 15 are separated from each other by rotating, so that the supporting rod 15 can slide in the inside of the mounting ring 11, when the supporting rod 15 is slid to a suitable position, the third self-tapping screw 16 and the slot at the top of the supporting rod 15 are connected to each other, so as to fix the position of the supporting rod 15 in the inside of the mounting ring 11.

[0035] The illuminating lamp 20 is arranged in the inside of the ball seat 17 through the ball core 19, when the fixed threaded sleeve 18 and the ball seat 17 are separated from each other, the ball core 19 can rotate at any angle in the inside of the illuminating lamp 20, so as to adjust the irradiation angle of the illuminating lamp 20, and the ball core 19 can be taken out from the inside of the ball seat 17, so as to conveniently replace the illuminating lamp 20 of different specifications, when the ball core 19 is arranged in the inside of the ball seat 17 and the fixed threaded sleeve 18 is arranged at the outside of the ball seat 17, the position of the ball core 19 in the inside of the ball seat 17 is fixed by the fixed threaded sleeve 18, so as to fix the angle of the illuminating lamp 20.
