Problems solved by technology

[0003] The prior art table lamp projection structure is simple in structure, it is inconvenient to observe and display from multiple angles when displaying and reflecting the model, and it is inconvenient to clamp and fix different models and different positions of the model, thereby making the display form of the model relatively Poor, so that students have relatively poor perception of the shadow structure reflected in different perspectives

Embodiment 1

[0030] see figure 1 , a table lamp projection structure for painting design teaching of the present invention, comprising a base 1, a pad 2, a rod seat 3, a chute 4, a clamping mechanism 5, a rotating head 6, a protective shell 7, a lamp tube 8, a control The switch 9, the power cord 10, the four ends of the bottom of the bottom platform 1 are bonded and fixed with the spacer 2, the inner rear and middle side of the bottom platform 1 is rotated and connected with the rod seat 3, the front middle side of the rod seat 3 is provided with a chute 4, and the rod seat 3 The top on the right side is connected to the rotating head 6 in rotation, the front end of the rotating head 6 is connected with a protective shell 7, the inner bottom of the protective shell 7 is embedded with a lamp tube 8, and the right rear side of the top of the base 1 is provided with a control switch 9 and a power cord 10 It is arranged on the right side of the rear part of the base 1 , and the clamping mecha...

Embodiment 2

[0036] In a table lamp projection structure for painting design teaching of the present invention, the support block 5166 is arc-shaped, and the front end surface of the support block 5166 slides up and down with the inner wall of the housing 511 to facilitate the support of the rotating rod 5165, the driving bevel gear 5163 and the driven The bevel gears 5164 have the same structure and size, and the angle formed between the driving bevel gear 5163 and the driven bevel gear 5164 is 90 degrees, which is conducive to steering transmission. The front side of the hollow tube 54 is embedded with a bearing sleeve and is hollow. The inner side of the pipe 54 is provided with a groove, and the cross bar 5529 runs through the inner side of the groove of the bearing sleeve inside the hollow pipe 54, and the outer surface of the cross bar 5529 is connected to the groove in rotation, and the rear end surface of the cross bar 5529 is connected with the rotating rod 5165 at the same time. I...

Abstract

The invention discloses a table lamp projection structure for painting design teaching, which comprises a bottom table, a cushion block, a rod seat, a sliding groove, a clamping mechanism, a rotatinghead, a protective shell, a lamp tube, a control switch and a power line. According to the invention, the clamping mechanism is optimally arranged, and the driving motor is used as a power source, through cooperation of a threaded rod and an internal thread supporting sleeve, a steering assembly drives the height position of a containing assembly to be adjusted, then a rack frame is made to transversely move under the action of a servo motor, and therefore under the action of a first gear and a second gear, a front clamping block and a rear clamping block are driven to get close to each otherand get away from each other; and therefore, different parts of different models can be clamped and fixed, an operator can conveniently display the models in various forms, and the perceptibility of students to shadow structures embodied from different visual angles is improved.

Description

technical field [0001] The invention relates to the related field of painting design, in particular to a desk lamp projection structure for painting design teaching. Background technique [0002] Painting is the most important art form in plastic arts. It refers to the use of artistic languages ​​such as lines, colors and shapes to create static visual images in two-dimensional space (that is, plane) through artistic means such as shape, color and composition. The image is an art form that expresses the author's aesthetic feelings; currently, in the process of art teaching, students need to use the table lamp projection structure to display the model and display the shadows reflected by different perspectives of the model. [0003] The prior art table lamp projection structure is simple in structure, it is inconvenient to observe and display from multiple angles when displaying and reflecting the model, and it is inconvenient to clamp and fix different models and different p...
