[0022] The present invention will be further described below with reference to the accompanying drawings:
[0023] Example
[0024] Reference Figure 1-4 A keyboard key printing and fixing fixture includes a base 1 and a keyboard tray 6. A connecting structure is fixedly installed on the base 1 to ensure overall stability. A horizontal indicator structure is fixedly installed on the connecting structure to check whether the keys on the upper surface of the keyboard 16 are at the same height. The keyboard tray 6 is rotatably connected to the connecting structure. The connecting structure ensures the stability between the keyboard tray 6 and the base 1, and allows the keyboard tray 6 to rotate. The rotation of the keyboard tray 6 allows for horizontal adjustment of the keys on the keyboard 16. The horizontal indicator structure is located above the keyboard tray 6, which is above the base 1. A positioning limiter is rotatably installed on the keyboard tray 6 to position the keyboard 16. The limiter makes pressing contact with the keyboard 16 to fix the keyboard 16 and ensure its stability on the keyboard tray 6.
[0025] In this embodiment, the connecting structure includes a U-shaped frame plate 2 and a countersunk shaft hole 3. The U-shaped frame plate 2 is fixedly installed on one side above the base 1. The length of the U-shaped frame plate 2 is the same as the length of the base 1. The opening of the U-shaped frame plate 2 faces the center of the base 1. The U-shaped frame plate 2 can support the keyboard tray 6, so that a certain rotation space is formed between the keyboard tray 6 and the base 1. A countersunk shaft hole 3 is provided through both ends of the opening of the U-shaped frame plate 2. The countersunk shaft hole 3 is provided to ensure the stability and smoothness of the keyboard tray 6 during rotation. The large hole of the countersunk shaft hole 3 faces the center of the opening of the U-shaped frame plate 2. One of the smaller openings of the countersunk shaft hole 3 is provided with an internal thread for connection with the adjusting bolt 9. After the adjusting bolt 9 is separated from the threaded hole 8, it prevents the adjusting bolt 9 from falling off the U-shaped frame plate 2. The keyboard tray 6 is rotatably connected to the corresponding countersunk shaft hole 3.
[0026] In this embodiment, a pivot 7 is fixedly installed at each end of one side of the keyboard tray 6. The pivot 7 is rotatably installed in the large hole of the corresponding countersunk shaft hole 3. The pivot 7 ensures the stability between the keyboard tray 6 and the U-shaped frame plate 2. After the adjusting bolt 9 is separated from the pivot 7, the keyboard tray 6 is prevented from falling off the U-shaped frame plate 2.
[0027] In this embodiment, a threaded hole 8 is coaxially opened at the outer end of one of the rotating shafts 7. An adjusting bolt 9 is threadedly installed between the threaded hole 8 and one of the countersunk shaft holes 3. After adjusting the support angle of the keyboard tray 6 on the keyboard 16, the keyboard tray 6 and the U-shaped frame 2 are fixed to prevent accidental rotation. The adjusting bolt 9 is located on the outside of the U-shaped frame 2. The inner diameter of the threaded hole 8 is the same as the inner diameter of the threaded opening of the countersunk shaft hole 3.
[0028] In this embodiment, the upper surface of the keyboard tray 6 is provided with a U-shaped cavity 10 for placing the keyboard 16. The orientation of the U-shaped cavity 10 is consistent with the orientation of the U-shaped frame 2, so as to position the keyboard 16 when placing it and to facilitate the picking up and putting down of the keyboard 16.
[0029] In this embodiment, the horizontal indicator structure includes a telescopic rod 4 and a horizontal indicator plate 5. The telescopic rod 4 can be an electric telescopic rod or a manual telescopic rod. The telescopic rod 4 is fixedly installed at one corner of the U-shaped frame plate 2. By setting the telescopic rod 4, the distance between the horizontal indicator plate 5 and the keyboard tray 6 can be adjusted to accommodate keyboards 16 of various thicknesses. The output end of the telescopic rod 4 is fixedly connected to one end of the horizontal indicator plate 5 in a vertical manner. The inner side of the horizontal indicator plate 5 is flush with the side of the U-shaped cavity 10 near the horizontal indicator plate 5. The horizontal indicator plate 5 is set parallel to the base 1 and is above the keyboard tray 6. By setting the horizontal indicator plate 5, it is possible to determine whether the keys on the keyboard 16 are parallel to the horizontal indicator plate 5.
[0030] In this embodiment, the limiter includes a second rotating shaft 11, a second threaded hole 12, a bushing 13, a positioning rod 14, and a second adjusting bolt 15. The second rotating shaft 11 is fixedly installed at one apex of the U-shaped cavity 10 on the upper surface of the keyboard tray 6. The second rotating shaft 11 has a second threaded hole 12 coaxially formed on it. The bushing 13 is rotatably sleeved on the second rotating shaft 11. Through the arrangement of the bushing 13 and the second rotating shaft 11, the positioning rod 14 can be rotated to adjust its angle, so that the positioning rod 14 contacts the keyboard 16 in the U-shaped cavity 10, thereby facilitating the adjustment of keyboards 16 of various sizes. The bushing 13 is fixedly connected to one end of the positioning rod 14. The bushing 13 and the threaded hole 12 are fixedly installed with an adjusting bolt 15 by means of threads. By adjusting the angle of the positioning rod 14, the bushing 13 and the rotating shaft 11 can be fixed to prevent them from rotating accidentally. The positioning rod 14 is located in the U-shaped cavity 10 and is set parallel to the keyboard tray 6. The length of the positioning rod 14 is less than the width of the U-shaped cavity 10. The positioning rod 14 is used to press and fix the keyboard 16 in the U-shaped cavity 10.
[0031] In specific use, this utility model is first fixed to the required printing equipment via the base 1;
[0032] When printing the keys on keyboard 16, if keyboard 16 has a certain degree of tilt, such as Figure 1 Place the keyboard 16 in the U-shaped cavity 10, with one of the top corners of the keyboard 16 close to the top corner of the U-shaped cavity 10 near the horizontal indicator plate 5, and with the lowest point of the keyboard 16 facing the opening of the U-shaped cavity 10; then loosen the adjusting bolt 2 15, rotate the positioning rod 14 until it contacts the keyboard 16, and then tighten the adjusting bolt 2 15. This completes the fixing of the keyboard 16.
[0033] Then loosen the adjusting bolt 9, rotate the keyboard tray 6 until all the keys on the keyboard 16 are parallel to the horizontal indicator plate 5, and tighten the adjusting bolt 9 to print the keys on the keyboard 16.
[0034] After printing is complete, keep the overall structure still and simply pull the keyboard 16 towards the opening of the U-shaped cavity 10 to remove it. This avoids the hassle of adjusting the level back and forth when printing keys on the same keyboard 16, and makes it more convenient and faster to fix the keyboard 16 in place later.
[0035] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
