[0019] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0020] Please refer to Figures 1 to 4 As shown, an embodiment of this utility model provides a handheld inkjet printer adapted to a curved surface, including a handheld inkjet printer body 1 and an inkjet printer bracket adapted to a curved surface. The handheld inkjet printer body 1 is fixedly installed on the inkjet printer bracket. The inkjet printer bracket includes a connecting plate 2, and adjustable seats 3 are installed on both sides of the connecting plate 2 at adjustable angles. Rollers 4 are rotatably installed on the adjustable seats 3.

[0021] By adopting the above technical solution, the handheld inkjet printer body 1 is adapted to the arc surface through the inkjet bracket, and the connecting plate 2 provides basic support for the overall structure; the adjustment seat 3 can be adjusted to adapt to arc surfaces with different curvatures, ensuring that the roller 4 can fit the arc surface; the roller 4 rotates on the adjustment seat 3, which can reduce the friction between the inkjet printer and the arc surface when it moves, and at the same time ensure the relative position of the handheld inkjet printer body 1 and the arc surface is stable, ensuring that the inkjet printing process is carried out smoothly.

[0022] In this embodiment, the connecting plate 2 has a socket 201, and the printhead of the handheld inkjet printer body 1 is inserted into the socket 201.

[0023] By adopting the above technical solution, the insertion hole 201 on the connecting plate 2 provides initial positioning for the printhead of the handheld inkjet printer body 1. Through the insertion and engagement, the printhead and the connecting plate 2 form a relatively fixed positional relationship, ensuring that the printing direction of the printhead maintains an appropriate angle with the arc surface, thus providing a basic positioning for accurate inkjet printing.

[0024] In this embodiment, the connecting plate 2 is fixedly connected to the connecting ears 202 on both sides of the socket 201, and the printhead of the handheld inkjet printer body 1 is fixedly connected to the connecting ears 202 by the first screw.

[0025] By adopting the above technical solution, the connecting ears 202 on both sides of the socket 201 fasten the printhead of the handheld inkjet printer body 1 to the connecting plate 2 with the first screw, thereby enhancing the connection stability on the basis of the initial insertion and positioning, preventing the printhead from loosening due to vibration or movement during the inkjet printing process, and ensuring the accuracy of the printing position.

[0026] In this embodiment, an adjustment plate 5 is installed on the top of the connecting plate 2. Both ends of the adjustment plate 5 are provided with arc-shaped waist holes 501. An adjustment bolt 303 is inserted into the arc-shaped waist holes 501. A connecting block 301 is fixedly connected to the top of the adjustment seat 3. A threaded hole 302 is provided on the top of the connecting block 301. The lower end of the adjustment bolt 303 is threaded into the threaded hole 302.

[0027] By adopting the above technical solution, the arc-shaped waist hole 501 on the adjusting plate 5 provides a movement trajectory for the adjusting bolt 303. By loosening the adjusting bolt 303, it can slide along the arc-shaped waist hole 501, which can drive the connecting block 301 and the adjusting seat 3 to rotate synchronously, thereby realizing the angle adjustment of the adjusting seat 3. After the adjustment is in place, tighten the adjusting bolt 303 to make it secure with the threaded hole 302 of the connecting block 301, thereby fixing the angle of the adjusting seat 3 to adapt to the arc surface with a specific curvature.

[0028] In this embodiment, the arc of the arc-shaped waist hole 501 is 30°-70°.

[0029] By adopting the above technical solution, the arc range of the arc-shaped waist hole 501 from 30° to 70° limits the moving angle of the adjusting bolt 303, thereby limiting the angle adjustment range of the adjusting seat 3. This range can cover the curvature requirements of most common arc surfaces.

[0030] In this embodiment, both ends of the adjusting plate 5 are provided with through holes, and locking bolts 502 are provided in the through holes. The adjusting plate 5 is fixed to the connecting plate 2 by the locking bolts 502.

[0031] By adopting the above technical solution, the through holes at both ends of the adjusting plate 5 allow the studs 502 of the locking bolts to pass through. The adjusting plate 5 and the connecting plate 2 are fastened together by the locking bolts 502 to prevent the adjusting plate 5 from shifting relative to the connecting plate 2 during the coding process. This ensures that the guiding effect of the arc-shaped waist hole 501 on the adjusting bolt 303 is stable, thereby ensuring the stability of the angle of the adjusting seat 3.

[0032] In this embodiment, the adjusting seat 3 is arranged in the shape of a c, and the second rotating shaft 401 is rotatably installed on the inner side of the adjusting seat 3, and the roller 4 is fixedly sleeved on the second rotating shaft 401.

[0033] By adopting the above technical solution, the C-shaped adjustment seat 3 provides a stable installation space for the second rotating shaft 401, which can rotate inside the adjustment seat 3, thereby driving the roller 4 to rotate synchronously. This structure allows the roller 4 to flexibly adapt to the curvature of the arc surface. When the inkjet printer moves along the arc surface, the roller 4 rolls smoothly, reducing frictional damage to the arc surface, while ensuring the overall movement stability of the inkjet printer.

[0034] In this embodiment, two rollers 4 are sleeved on the same second rotating shaft 401, and the distance between the two rollers 4 is greater than the longitudinal length of the insertion hole 201.

[0035] By adopting the above technical solution, the two rollers 4 on the same second rotating shaft 401 form a two-point support structure, and the distance between them is greater than the longitudinal length of the insertion hole 201, ensuring that the printhead of the handheld inkjet printer body 1 is within the support range of the two rollers 4, so that the rollers 4 will not cause friction on the sprayed area during the inkjet printing process.

[0036] In this embodiment, a locking hole is provided on the sleeve of the roller 4, and a second screw for fixing the sleeve to the second rotating shaft 401 is installed in the locking hole.

[0037] By adopting the above technical solution, the sleeve of the roller 4 is fixed to the second rotating shaft 401 through the locking hole and the second screw, which can prevent the roller 4 from sliding axially relative to the second rotating shaft 401 during rotation, ensuring that the rolling trajectory of the roller 4 is consistent with the rotation trajectory of the second rotating shaft 401, avoiding the offset of the inkjet printer's movement trajectory due to the displacement of the roller 4, and ensuring the accuracy of the inkjet printing position.

[0038] In this embodiment, the first rotating shaft 203 is fixedly connected to both sides of the connecting plate 2, and the adjusting seat 3 is rotatably sleeved on the first rotating shaft 203.

[0039] By adopting the above technical solution, the first rotating shaft 203 on both sides of the connecting plate 2 provides a stable rotation fulcrum for the adjusting seat 3. The adjusting seat 3 can rotate around the first rotating shaft 203. The adjustment structure of the arc-shaped waist hole 501 and the adjusting bolt 303 makes the angle adjustment of the adjusting seat 3 more stable and precise, ensuring that the roller 4 can closely fit the arc surface with different curvatures and improve the inkjet printing adaptability.
