Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of the utility model protection.
As shown in Figure 1, a kind of Machine Design drawing table according to the utility model embodiment, comprise base 1, described base 1 is provided with swivel plate 2, swivel plate 2 is rotationally connected with on base 1 by central rotating shaft 3, described swivel plate 2 is fixed with two hydraulic stems 4, top between two hydraulic stems 4 is connected with arc-shaped seat 5, described arc-shaped seat 5 is connected with arcuate member 6 by slide, arcuate member 6 is provided with desktop 7, described desktop 7 is provided with groove, wherein, one end inwall of described groove is arc, the inwall of this arc is connected with hang plate 8 by axis of rotation, the medial surface of hang plate 8 is provided with LED lamp bead.
Described base 1 is provided with some pulleys 9, and described pulley 9 is provided with fixing button 10.
Described base 1 is provided with circular groove, and described swivel plate 2 bottom is provided with some back-up blocks 11 coordinated with circular groove.
Described hydraulic stem 4 is provided with and starts button 12.
Fixed block 13 is provided with between described arc-shaped seat 5 and arcuate member 6.
Described arcuate member 6 is fixedly connected with by some support bars 14 with between desktop 7.
The outside of described hang plate 8 is frosting.
Conveniently understand technique scheme of the present utility model, below by way of in concrete occupation mode, technique scheme of the present utility model is described in detail.
When specifically using, according to Machine Design drawing table described in the utility model:
Can the direction of horizontal adjustment desktop 7 by swivel plate 2, be connected with arcuate member 6 according on arc-shaped seat 5 by slide simultaneously, the angle of desktop 7 can be adjusted, desktop 7 is provided with hang plate 8, and hang plate 8 inner face is LED lamp bead, illuminates inner side when can be used for student to operate in groove, if when student operates outside hang plate 8 simultaneously, its face is frosting, can increasing friction force, prevents the articles for use landing be placed on it;
This drawing table can also be moved by pulley 9, after moving to correct position, just can be locked by fixing button 10, drawing table is fixed.
In sum, by means of technique scheme of the present utility model, the utility model can the adjustment angle of three dimensions, be applicable to user to use under various posture or situation, simple and practical, easy to operate understandable, and the mode variation used, has good development prospect.
