[0021] The utility model will be explained further in detail now in combination with the drawings. The drawings are simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so it only shows the structure related to the utility model.

[0022] Please refer to Figures 1-6 A base surface spraying area fixed template, including template assembly 1, the template assembly 1 includes upper frame body 2 and lower frame body 3, the upper frame body 2 and lower frame body 3 are fixedly connected through the L-shaped support plate 4 at four corners, the periphery of the template assembly 1 is equipped with the flexible protective curtain 5 that can be lifted and lowered, the top of the upper frame body 2 is equipped with the detachable protective cover 10, the bottom surface of the lower frame body 3 is equipped with a plurality of suction cups 31, and a plurality of the suction cups are arranged along the bottom periphery of the lower frame body.

[0023] In the embodiment, the protective cover 10 is of transparent material, and the material is preferably organic glass (acrylic) or transparent plastic plate. The protective cover 10 is hollow and has a through hole at the top for the spray head to extend into. During use, the spray head extends into the protective cover to spray into the template assembly 1. After use, the protective cover 10 can be opened or detached for cleaning. The flexible protective curtain 5 is a tarpaulin curtain, which is made of the same material as a raincoat or an umbrella and can block water and prevent paint splashing.

[0024] During use, the template assembly 1 is placed on the base surface to be repaired and is adsorbed to the base surface by the suction cups around the bottom of the lower frame body, thereby ensuring the stability of the whole. Then, the flexible protective curtain 5 is lifted to a predetermined height to ensure that it can block the paint splashing. Then, the spray head is extended into the template assembly 1 from the protective cover 10 to start the spraying work.

[0025] Specifically, the L-shaped drive plates 7 are arranged opposite each other between the upper frame body 2 and the lower frame body 3. The top of the flexible protective curtain 5 is fixed to the bottom surface of the L-shaped drive plate 7, and the bottom of the flexible protective curtain 5 falls downward by its own gravity. The flexible protective curtain 5 below the two L-shaped drive plates 7 blocks the periphery of the template assembly 1. At this time, the paint splashing inside is blocked by the flexible protective curtain 5, thereby avoiding the scattering of the paint. At the same time, the whole can directly spray and repair the defect part, thereby improving the repair accuracy.

[0026] In the embodiment, two synchronous servo motors 8 are arranged on the surface of the upper frame body 2 at opposite angles, the output shafts of the servo motors 8 are in transmission connection with the top end of a lead screw 9 penetrating through the upper frame body 2, the bottom end of the lead screw 9 extends downward through the corner of the L-shaped driving plate 7, the extension end of the bottom of the lead screw 9 is in rotation connection with the lower frame body 3, and the L-shaped driving plate 7 is lifted and lowered by the operation of the servo motor 8, so that the flexible protective curtain 5 is also lifted and lowered.

[0027] The end of the L-shaped driving plate 7 is further provided with a sliding block 71, and the inner wall of the L-shaped support plate 4 is provided with a sliding groove matched with the sliding block 71, wherein the sliding block 71 is always arranged in the sliding groove, and the sliding block 71 vertically slides along the sliding groove when the L-shaped driving plate 7 is lifted and lowered.

[0028] That is, the lead screw 9 and the L-shaped driving plate 7 are connected through thread cooperation, and when the servo motor 8 operates, the lead screw 9 starts to rotate, and since the lead screw 9 and the L-shaped driving plate 7 are connected through thread cooperation, the L-shaped driving plate 7 is lifted and lowered, so that the flexible protective curtain 5 is lifted or pulled down, the lifting and lowering of the flexible protective curtain 5 is realized, the height protection of different spraying positions is met, and the practicability is high.

[0029] In use, in order to avoid that the flexible protective curtain 5 accumulates into the template assembly, a plurality of limiting rods 6 are further arranged between the upper frame body 2 and the lower frame body 3 around, and the limiting rods 6 are arranged on the inner side of the flexible protective curtain 5; at this time, since the limiting rods 6 block the flexible protective curtain 5 inside, no matter how the flexible protective curtain 5 is lifted and lowered, the flexible protective curtain 5 is always outside the limiting rods 6, so that the flexible protective curtain 5 is prevented from accumulating into the template assembly and affecting the spraying repair.

[0030] Obviously, the above embodiment is only an example for clearly illustrating, and does not limit the implementation. For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the implementation is not required and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
