Description

Technical Field

[0001] The invention relates to the technical field of painting devices, and in particular to a lifting type painting device for indoor painting teaching. Background Art

[0002] A specially designed device or tool that aims to improve the effectiveness and efficiency of painting teaching, provide support to learners, and promote their development of painting skills and creative expression. These devices usually integrate multiple functions to meet different teaching needs and painting styles. Its main purpose is to help students better understand and master painting skills by optimizing the learning environment, providing necessary tools and materials, and enhancing teaching interaction. The purpose is to promote the technical improvement and creative development of painting learners by providing an optimized learning environment and support system. The lifting function provides students with greater flexibility and can be adjusted according to the painting content and personal preferences, thereby optimizing the creative experience. The lifting function provides more flexibility and convenience for indoor painting teaching, which helps to improve students' learning experience and painting results.

[0003] For example, the public document with announcement number CN108041823A, publication date May 18, 2018, and patent name "A Multifunctional Art Painting Display Table" discloses a multifunctional art painting display table, which realizes the lifting function of the table body by means of a first electric telescopic rod, and then realizes the adjustment of the specific height of the table body according to the painting or display needs of the painter, realizes the painting function of the painter by means of a drawing board, realizes the color mixing effect of the painting pigment by means of a color mixing grid, heats the inside of the color mixing tank by means of a heating plate, avoids affecting the solid-liquid state of the pigment and thus affecting the painting effect when the temperature is too low, realizes the support function of the mobile phone or tablet computer by means of a bracket plate, and realizes the height adjustment of the first movable plate by adjusting the position of the electric slider on the electric slide rail according to the height of the mobile phone or tablet computer by means of an intelligent controller, and realizes the light supplement function in the drawing state by means of a desk lamp, thereby avoiding the influence of low light on the drawing effect.

Fine-adjustment of the correct angle ensures that the correct sitting posture is corrected to achieve the angle and position suitable for oneself, and then through The casters 13 installed on the table legs 12 can move the painting device indoors. At the same time, the fixed blocks 14 installed on the front side of the table legs 12 are stabilized, and the foot pads 34 at the bottom of the fixed blocks 14 can prevent the painting device from sliding as a whole when in use. The electronic products and related electronic devices on the table top 1 and the table top 2 can be charged through the socket 28, and then the multifunctional drawer 25 at the bottom of the table top 1 is on the inner slide rail 23, so that the inner slide rail 23 moves on the inner wall of the outer slide rail 24, so that the pulling distance can ensure that the drawer is within the working range. The drawer can also manage its own items in different areas, and the limit block 30 is driven by pulling the pull rod 29. The light module 21 is moved so that the spring 31 is compressed, thereby driving the positioning rod 32 to rotate in a directional manner on the inner wall of the slider 20, and then the two sides of the positioning rod 32 are extended and retracted, thereby pulling the fixing rod 33 to the inner wall of the slider 20, and then placing the light module 21 in the groove of the slider 20. Conversely, the pull rod 29 is released, and the fixing rod 33 is inserted into the groove of the light module 21 under the action of the elastic force of the spring 31, so as to facilitate the installation and subsequent replacement of the light module 21, and then the light module 21 can be moved in the directional groove of the table top 1 to meet the needs of night learning and painting at different positions on the table top 1.
