Description

Technical Field

[0001] This utility model belongs to the field of painting device technology, and in particular relates to an interactive mechanical painting device. Background Technology

[0002] Most children's drawing devices on the market today are hand-cranked, resulting in fixed and monotonous drawing patterns that lack interactivity and creativity, causing children to easily lose interest. Furthermore, existing devices typically only generate a limited number of line patterns, failing to meet children's needs for diverse drawing experiences.

[0003] Therefore, there is an urgent need for a mechanical painting device that is easy to operate and offers diverse painting effects to enhance children's creativity and hands-on skills. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide an interactive mechanical painting device, which aims to solve the problems mentioned in the background art.

[0005] This utility model embodiment is implemented as follows: an interactive mechanical painting device includes an outer frame, on which a motorized painting turntable for holding drawing paper is disposed, and further includes:

[0006] The painting module includes a left electric turntable, a right electric turntable, and a painting arm. The painting arm includes two long connecting rods and two short connecting rods. The middle parts of the two long connecting rods are hinged to each other to form an X-shaped structure. One end of the two short connecting rods is hinged to each other to form a V-shaped structure. The free ends of the two short connecting rods are respectively connected to one end of the two long connecting rods. The hinged ends of the two short connecting rods are also provided with a placeholder for placing paintbrushes. The ends of the two long connecting rods away from the short connecting rods are respectively mounted on the left and right electric turntables.

[0007] In a further technical solution, the outer frame is also provided with a second speed control knob for adjusting the rotation speed of the left electric turntable, and a third speed control knob for adjusting the rotation speed of the right electric turntable.

[0008] In a further technical solution, the electric painting turntable is rotatably mounted on an external frame, and the external frame is also equipped with a first motor for driving the electric painting turntable to rotate, and the external frame is also provided with a first speed control knob for controlling the speed of the first motor.

[0009] In a further technical solution, a start / stop switch is also provided on the external frame, which is used to control the start and stop of the second motor, the third motor and the first motor.

[0010] This utility model provides an interactive mechanical painting device. In use, a paintbrush is mounted on a base, and then the left and right electric turntables are adjusted. Since the painting arm is eccentrically mounted on the left and right electric turntables, adjusting these turntables causes the painting arm to swing, thus moving the paintbrush and drawing lines on the turntables. The device controls the rotation speed of the corresponding turntables by adjusting three speed control knobs. The different rotation speeds alter the movement trajectory of the painting arm, resulting in the creation of different line patterns and effectively enhancing the interactivity of the painting device.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0016] like Figure 1 and Figure 2 As shown, an interactive mechanical painting device according to an embodiment of the present invention includes an outer frame 1, on which a motorized painting turntable 5 for holding drawing paper is provided, and further includes:

[0017] The painting module includes a left electric turntable 2, a right electric turntable 3, and a painting arm 4. The painting arm 4 includes two long connecting rods and two short connecting rods. The middle parts of the two long connecting rods are hinged to each other to form an X-shaped structure. One end of the two short connecting rods is hinged to each other to form a V-shaped structure. The free ends of the two short connecting rods are respectively connected to one end of the two long connecting rods. The hinged ends of the two short connecting rods are also provided with a place to hold a paintbrush. The ends of the two long connecting rods away from the short connecting rods are respectively mounted on the left electric turntable 2 and the right electric turntable 3.

[0018] In this embodiment of the utility model, when in use, the paintbrush is installed on the base, and then the left electric turntable 2 and the right electric turntable 3 are adjusted. Since the painting arm 4 is eccentrically installed on the left electric turntable 2 and the right electric turntable 3, the painting arm 4 can be driven to swing by adjusting the left electric turntable 2 and the right electric turntable 3. Thus, the painting arm 4 drives the paintbrush to swing, and lines can be drawn on the painting electric turntable 5.

[0019] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, the outer frame 1 is further provided with a second speed control knob 6 for adjusting the rotational speed of the left electric turntable 2, and a third speed control knob 7 for adjusting the rotational speed of the right electric turntable 3.
