Detailed Implementation

[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 computer keyboard casing spraying fixture includes a base 1, a protective shell 2 mounted on the base 1, a movable seat 3 rotatably mounted on the protective shell 2, a servo motor 4 mounted on the bottom wall of the movable seat 3, the output shaft of the servo motor 4 passing through the movable seat 3 and connected to a rotating ring 5, the rotating ring 5 having several arc-shaped grooves 6, each of the arc-shaped grooves 6 being slidably fitted with a connecting shaft 7, the bottom end of each of the connecting shafts 7 being connected to a moving rod 8, the moving rod 8 being slidably connected to the movable seat 3, and the top of each of the moving rod 8 being fitted with a clamping rod 11, a connecting plate 9 being installed inside the protective shell 2, a drive motor 10 being mounted on the bottom wall of the connecting plate 9, and the drive motor 10 passing through the connecting plate 9 and connected to the movable seat 3.

[0022] When the keyboard shell needs to be painted, the keyboard shell is first placed on the fixture with several clamping rods 11 inside the keyboard shell. Then, the servo motor 4 is started, and the servo motor 4 drives the rotating ring 5 to rotate synchronously. This causes several connecting shafts 7, which are slidably connected to the rotating ring 5 through the arc groove 6, to move. This causes several moving rods 8 and the clamping rods 11 mounted on the moving rods 8 to move outwards from the fixture until the clamping rods 11 are in close contact with the inner wall of the keyboard shell, thereby achieving the purpose of restricting the keyboard shell and thus meeting the requirements of the paint color. When different positions of the keyboard shell need to be painted, the user turns on the drive motor 10, which drives the moving seat 3 to rotate, thereby causing the keyboard shell on the fixture to rotate synchronously, thus achieving the purpose of painting different positions of the keyboard shell.

[0023] Specifically, in this embodiment, the movable base 3 is provided with a plurality of movable slots 12, and a plurality of movable rods 8 are slidably adapted in the corresponding movable slots 12, so that the plurality of movable rods 8 can be slidably connected to the movable base 3 through the corresponding movable slots 12. Thus, when the rotating ring 5 drives the connecting shaft 7 to move, the plurality of movable rods 8 are restricted by the movable slots 12, so that the movable rods 8 can only move along the direction of their corresponding movable slots 12, thereby allowing the plurality of movable rods 8 to move closer to or further away from each other, thereby completing the clamping work of the keyboard shell.

[0024] Specifically, in this embodiment, a U-shaped mounting plate 13 is installed on the bottom wall of the movable base 3, the servo motor 4 is located inside the U-shaped mounting plate 13, and the output shaft of the drive motor 10 is connected to the U-shaped mounting plate 13, so that the output end of the drive motor 10 can be connected to the movable base 3 through the U-shaped mounting plate 13, thereby enabling the drive motor 10 to drive the movable base 3 to rotate synchronously when it rotates, thereby achieving the purpose of adjusting the position of the keyboard shell.

[0025] Specifically, in this embodiment, a limiting ring 14 is installed on the bottom wall of the movable seat 3, and a limiting groove 15 is installed on the protective shell 2. The limiting ring 14 is slidably adapted to the limiting groove 15, so that the movable seat 3 can be slidably connected to the protective shell 2 through the adaptation of the limiting ring 14 and the limiting groove 15, thereby ensuring the rotation state of the movable seat 3.

[0026] Specifically, in this embodiment, a support shell 16 is installed on the top of the movable base 3, the rotating ring 5 is located inside the support shell 16, and the support shell 16 is provided with a plurality of connecting grooves 17. The clamping rods 11 are adapted to the connecting grooves 17. The support shell 16 provides protection for the rotating ring 5, preventing damage caused by external objects when the rotating ring 5 is in operation, thereby improving the service life of the device. The plurality of connecting grooves 17 allow the clamping rods 11 to pass through the support shell 16 through the corresponding connecting grooves 17, making it convenient for the clamping rods 11 to clamp the keyboard shell.

[0027] Specifically, in this embodiment, a support plate 18 is installed on each of the clamping rods 11. The support plate 18 is located above the support shell 16, so that when the clamping rods 11 clamp the keyboard shell, a part of the keyboard shell will contact the support plate 18, thereby providing partial support for the keyboard shell. At the same time, the support plate 18 can cover the connecting groove 17, thereby preventing pigment from entering the fixture through the connecting groove 17 during spraying, which would contaminate the internal parts and affect the service life of the fixture.

[0028] Specifically, in this embodiment, a rubber pad 19 is movably sleeved on each of the clamping rods 11, so that when the keyboard shell comes into contact with the clamping rods 11, the rubber pad 19 sleeved on the clamping rods 11 will first come into contact with the wall surface of the keyboard shell, thereby providing protection for the keyboard shell through the rubber pad 19 and preventing damage to the keyboard shell.

[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.
