DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 , 2 3. The utility model provides a technical solution: a projection painting toy, comprising a lower shell 1 and an upper shell 2, the lower shell 1 and the upper shell 2 are rotatably connected via a suspended shaft 3, the suspended shaft 3 enables the upper shell 2 to stay at a fixed opening and closing angle when opened, a drawing paper slot 11 is provided inside the lower shell 1, when drawing, paper is placed inside the drawing paper slot 11, the upper shell 2 is rotatably connected to a loading platform 21 (the inner side of the upper shell 2 is symmetrically connected to a hinge seat 22, the loading platform 21 is rotatably connected to the hinge seat 22 The inner side of the upper shell 2 is also integrally connected with a plurality of supporting protrusions 23, and when the stage 21 is rotated to a horizontal position, it is supported by the supporting protrusions 23). A reference object 4 is placed on the stage 21. After the reference object 4 is placed on the stage 21, the opening and closing angle of the upper shell 2 can be adjusted according to the projection effect and position. The internal rotation of the suspension shaft 3 is connected with an axle seat 5, and a projection board 6 of a black and transparent material is inserted and fixed inside the axle seat 5. The reflection of the reference object 4 can be reflected on the projection board 6 through light reflection.

[0021] See also Figure 4 The suspension shaft 3 includes a sleeve 31 fixedly connected to the lower shell 1 and a shaft core 32 fixedly connected to the upper shell 2. The shaft core 32 rotates inside the sleeve 31. The inner wall of the sleeve 31 is integrally connected with a plurality of positioning protrusions 33. The surface of the shaft core 32 is provided with a plurality of slots 34. The engaging surfaces of the positioning protrusions 33 and the slots 34 are hemispherical surfaces. The surface of the sleeve 31 is symmetrically provided with limiting slots 35. The shaft seat 5 is rotatably connected to the inside of the limiting slot 35. The relative rotation angle between the shaft seat 5 and the limiting slot 35 is 0-45°.

[0022] See also Figure 5 , 6 The surface of the shaft seat 5 is integrally connected with an outer protrusion 51, a slot 52 is provided inside the outer protrusion 51, and a second card slot 53 connected to the slot 52 is symmetrically provided at the top of the outer protrusion 51. The bottom end of the projection board 6 is integrally connected with an inserting plate 61, and the front and rear surfaces of the inserting plate 61 are integrally connected with a second card protrusion 62. When the projection board 6 needs to be assembled, the inserting plate 61 is inserted into the slot 52, and the card protrusion 62 and the second card slot 53 are engaged with each other.

[0023] When in use, the upper shell 2 is rotated to open. During the opening process, the shaft sleeve 31 and the shaft core 32 rotate relative to each other. During the relative rotation of the two, the locking protrusion 33 and the locking groove 34 also rotate relative to each other synchronously. When the opening angle of the upper shell 2 meets the use requirements, the locking protrusion 33 will engage with the corresponding locking groove 34. In this way, even if an obtuse angle is formed between the upper shell 2 and the lower shell 1, the angle will not continue to increase due to the self-weight of the upper shell 2, so that the purpose of making the upper shell 2 hover is achieved;

[0024] After the upper shell 2 is opened, the stage 21 is turned down, and the stage 21 rotates around the hinge seat 22. When the stage 21 rotates from vertical to horizontal, the support protrusion 23 supports the stage 21. At this time, the reference object 4 is placed on the stage 21, and the shaft seat 5 is moved to rotate inside the limit groove 35. After rotating to the right end, the projection board 6 is inserted on the shaft seat 5, and then the paper is placed in the drawing paper slot 11;

[0025] Under the action of light, the outline reflection of the reference object 4 is projected on the projection board 6. At this time, the corresponding outline reflection can be drawn on the paper according to the outline reflection, thereby realizing the function of projection painting.
