[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A multi-angle adjustable bracket for a visual inspection instrument includes an inspection platform 1, a support 2 on the inspection platform 1, a height adjustment mechanism 3 on the support 2, a rotary motor 4 on the moving end of the height adjustment mechanism 3, an arc-shaped slide rail 5 connected to the output shaft of the rotary motor 4, the arc-shaped slide rail 5 having a semi-circular structure with several worm gear teeth 6 on its outer curved surface, a movable seat 7 slidably connected to the arc-shaped slide rail 5, a worm 8 inside the movable seat 7 meshing with the worm gear teeth 6, the worm 8 being driven by a first servo motor 9, the bottom end of the movable seat 7 passing through the arc-shaped slide rail 5 and having a connecting seat 10, and a CCD inspection camera 11 detachably mounted on the connecting seat 10.

[0022] In use, the height adjustment mechanism 3 drives the arc-shaped slide rail 5 to move up and down synchronously, thereby adjusting the height of the CCD inspection camera 11. The operation of the rotating motor 4 causes the arc-shaped slide rail 5 to rotate around the motor 4, thus allowing the CCD inspection camera 11 to rotate synchronously. When the position of the CCD inspection camera 11 on the arc-shaped slide rail 5 needs adjustment, the first servo motor 9 is activated, driving the worm gear 8 to rotate. The meshing of the worm gear 8 with the worm wheel teeth 6 causes the moving seat 7 to move along the outer curved surface of the arc-shaped slide rail 5, allowing the CCD inspection camera 11 to move synchronously. This adjusts the position of the CCD inspection camera 11 on the arc-shaped slide rail 5, thereby adjusting the angle of the CCD inspection camera 11 to meet the needs of visual inspection at different angles.

[0023] Specifically, in this embodiment, the arc-shaped slide rail 5 is provided with two moving grooves 12, and the two side plates of the moving seat 7 are slidably connected to the moving grooves 12, so that the moving seat 7 can maintain its connection with the arc-shaped slide rail 5 through the moving grooves 12, and the moving grooves 12 are provided so that it can always be slidably connected to the arc-shaped slide rail 5, thereby providing conditions for the moving seat 7 to move along the outer curved surface of the arc-shaped slide rail 5.

[0024] Specifically, in this embodiment, the height adjustment mechanism 3 includes a second servo motor 31 mounted on the bracket 2. A threaded rod 32 is connected to the output shaft of the second servo motor 31. The threaded rod 32 is rotatably connected to the bracket 2, and a moving rod 33 is threaded onto the threaded rod 32. A rotating motor 4 is mounted on the moving rod 33. When height adjustment is required, the second servo motor 31 drives the threaded rod 32 to rotate, thereby driving the moving rod 33 to move vertically. The moving rod 33 then drives the arc-shaped slide rail 5 to move synchronously, thus achieving the purpose of height adjustment of the CCD inspection camera 11.

[0025] Specifically, in this embodiment, connecting grooves 34 are provided on both sides of the upper part of the bracket 2, and the threaded rod 32 is located in the connecting grooves 34. The connecting grooves 34 enable the threaded rod 32 to be rotatably connected to the bracket 2, and the wall of the bracket 2 provides protection for the threaded rod 32, preventing external impurities from seeping into the threaded rod 32 and affecting its normal operation.

[0026] Specifically, in this embodiment, the end of the movable rod 33 away from the threaded rod 32 is slidably connected to the connecting groove 34 in the vertical direction, so that when the movable rod 33 is driven by the threaded rod 32, the connecting groove 34 restricts the movement direction of the movable rod 33, so that the movable rod 33 can only move in the vertical direction, thereby making the CCD detection camera 11 only move in the vertical direction.

[0027] Specifically, in this embodiment, a bidirectional lead screw 13 is rotatably connected inside the connecting seat 10. A knob 14 is provided at the tail end of the bidirectional lead screw 13. The knob 14 is located outside the connecting seat 10. Two opposing clamping rods 15 are threaded onto the bidirectional lead screw 13, allowing the user to control the rotation of the bidirectional lead screw 13 by rotating the knob 14, thereby driving the two clamping rods 15 to move closer or further apart, so as to realize the installation and disassembly of the CCD inspection camera 11, thereby realizing the quick installation of the CCD inspection camera 11, so as to facilitate the maintenance of the CCD inspection camera 11.

[0028] Specifically, in this embodiment, the clamping ends of both clamping rods 15 are detachably provided with rubber pads 16, so that when the clamping rods 15 move toward the CCD inspection camera 11, the rubber pads 16 can contact the CCD inspection camera 11 before the clamping rods 15, thereby providing protection for the CCD inspection camera 11, avoiding wear during frequent installation, and extending the service life of the CCD inspection camera 11.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
