[0049] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0050] This utility model provides a foldable drawing device 100, including a first housing 100A, a second housing 100B, a first tool assembly 1012, and a second tool assembly 1022. The first tool assembly 1012 is inserted into the housing cavity 1011 of the first housing 100A, and the second tool assembly 1022 is inserted into the housing cavity 1021 of the second housing 100B. In one embodiment, the first tool assembly 1012 is connected to the housing cavity 1011 by a pull-out method, and the second tool assembly 1022 is similarly connected.

[0051] like Figure 1 As shown, the first side of the first housing 100A is hinged to the first side of the second housing 100B, and thus the first housing 100A can rotate between a first position and a second position along the first side.

[0052] like Figure 1 As shown, the first box 100A is in the first position. At this time, the surface of the first box 100A away from the second box 100B is opposite to the surface of the second box 100B away from the first box 100A, so that the first box 100A and the second box 100B are in a folded state.

[0053] Please refer to Figure 1Understand that the surface of the first housing 100A that is away from the second housing 100B is the outer surface of the first housing 100A, and the surface of the second housing 100B that is away from the first housing 100A is the outer surface of the second housing 100B. For example... Figure 2 As shown, the first box 100A is in the second position. At this time, the first box 100A and the second box 100B are in the unfolded state. The outer surface of the first box 100A and the outer surface of the second box 100B are on the same plane to form a drawing platform.

[0054] Those skilled in the art will understand that when the first box 100A and the second box 100B move relative to each other, their own structures do not change. It can be understood that, whether in a folded state or an unfolded state, the outer surface of the first box 100A is always the same surface, and so is the second box 100B.

[0055] This invention enables the drawing device to have a foldable function through the relative movement of the first box 100A and the second box 100B. It can not only store tool components, but also utilize part of the surface of the first box 100A and the second box 100B to extend into a drawing platform, improving the drawing environment. Furthermore, the structure is simple, the operation is easy, and the entire device is convenient to carry.

[0056] In one implementation, such as Figure 1 As shown, the edges of the first box 100A and the second box 100B are provided with a carrying rack (or handle) for easy lifting and gripping.

[0057] Furthermore, in one implementation, please refer to Figure 1 The first box body 100A includes a first box plate 103 and a first top plate 101. The side of the first top plate 101 is connected to the edge of the first box plate 103, and the box cavity 1011 of the first box body 100A is located on the first top plate 101.

[0058] When the first box 100A is in the first position, the surface of the first top plate 101 away from the first box plate 103 serves as the outer surface of the first box 100A.

[0059] The second box body 100B includes a second box plate 104 and a second top plate 102. The side of the second top plate 102 is connected to the edge of the second box plate 104, and the box cavity 1021 of the second box body 100B is located in the second top plate 102.

[0060] When the first housing 100A is in the first position, the surface of the second top plate 102 away from the second box plate 104 serves as the outer surface of the second housing 100B. This structure can be understood as follows: in this embodiment, the outer surfaces of the first top plate 101 and the second top plate 102 form a drawing platform in the unfolded state. In one embodiment, the surfaces of the first box plate 103 and the second box plate 104 away from the drawing platform are both provided with anti-slip pads.

[0061] In one implementation, please refer to Figure 3 The first tool assembly 1012 is a lead tool assembly, and the second tool assembly 1022 is a ruler assembly. In a further embodiment, both the first tool assembly 1012 and the second tool assembly 1022 also include a tool pad, on which both the lead tool assembly and the ruler assembly are placed. Furthermore, as... Figure 3 As shown, the tool pad has grooves that match the shape of the corresponding tool, and each tool is inserted into the corresponding groove.

[0062] Furthermore, such as Figure 4 As shown, in one embodiment, a first tilting component and a second tilting component are also included. In one exemplary embodiment, the first tilting component includes a first tilting bracket 113, the top of which is hinged to the surface of the first top plate 101 near the first box plate 103, and the first tilting bracket 113 is movable about its top in a direction toward or away from the first top plate 101. The bottom of the first tilting bracket 113 abuts against the surface of the first box plate 103 near the first top plate 101. The second tilting component includes a second tilting bracket 114, the top of which is hinged to the surface of the second top plate 102 near the second box plate 104, and the second tilting bracket 114 is movable about its top in a direction toward or away from the second top plate 102. The bottom of the second tilting bracket 114 abuts against the surface of the second box plate 104 near the second top plate 102. The first tilting bracket 113 and the second tilting bracket 114 can support the first top plate 101 and the second top plate 102 to tilt at a certain angle, making the drawing platform more adaptable to the drawing user's application scenarios. For example, during an exam, the foldable drawing device 100 of this utility model embodiment can be placed on a table, the tilting bracket can be raised, and the most comfortable drawing angle can be adjusted. For another example, in a tilted construction site, the angle can be adjusted using the tilting bracket.

[0063] For further details, please see Figure 4 and Figure 5The first tilting assembly also includes a first adjusting screw 115 and a first adjusting block 117. The surface of the first box plate 103 near the first top plate 101 is provided with a first groove 1031. The two ends of the first adjusting screw 115 are connected to the side wall of the first groove 1031 and its extension direction is consistent with the movement direction of the first tilting bracket 113. The first adjusting block 117 is engaged with the first adjusting screw 115 so as to slide along the extension direction of the first adjusting screw 115 under the drive of external force. The bottom of the first tilting bracket 113 is connected to the first adjusting block 117. Correspondingly, the second tilting assembly also includes a second adjusting screw 116 and a second adjusting block 118. A second groove 1041 is provided on the surface of the second box plate 104 near the second top plate 102. Both ends of the second adjusting screw 116 are connected to the sidewalls of the second groove 1041, and its extension direction is consistent with the movement direction of the second tilting bracket 114. The second adjusting block 118 engages with the second adjusting screw 116, allowing it to slide along the extension direction of the second adjusting screw 116 under the drive of an external force. The bottom of the second tilting bracket 114 is connected to the second adjusting block 118. Through the above structure, this embodiment of the invention can achieve multi-angle adjustment of the drawing platform to adapt to the needs of different application scenarios, further expanding the application scope of the foldable drawing device of this embodiment of the invention.

[0064] In a further embodiment, a latch is provided on the adjacent surfaces of the first top plate and the second top plate. When the first box and the second box are unfolded to form a drawing platform, the first top plate and the second top plate can be connected together through the latch. The drawer can lift the first top plate and the second top plate simultaneously to adjust the first tilting bracket and the second tilting bracket more quickly, avoiding the situation where the first top plate and the second top plate are misaligned when the tilt angles of the first top plate and the second top plate are adjusted separately.

[0065] For further details, please see Figure 6 and Figure 7 The foldable drawing device 100 also includes a locking assembly, which includes a first locking member 111 and a second locking member 112.
