Description

Drawing board high-angle support frame

The new type relates to a high-angle support frame for drawing boards for classroom desks.

The existing support frame mainly includes a flat support frame and a portable handle (referred to as a lifting frame). It is installed on the top of the drawing board. When in use, the support frame is bent about 90° and topped to the top of the drawing board to form a small-angle inclined plane with the placed desktop.

Take the standard of drawing drawings as an example. The German industrial standard A2 is used internationally, and the size is 420x594mm.

Normal school classroom desks, the desktop size is 400x600mm.

Therefore, the general lifting rack can only provide a small angle (about 10° or less) inclined surface.

At present, the mainstream of cartography education in the world is to use German Industrial Standard A2 drawings for drawing. However, the current drawing board has A2 (450x600mm) to correspond to it, which is cramped in size, and it is sufficient in size. If you change to a larger drawing board, such as the German Industrial Standard A2, you will face the situation that the desk top is too small to be placed. Therefore, the existing support frame needs to be improved.

In order to solve the problem of placing an ideal size on the desks of the existing classrooms, the enlarged drawing board that can draw German industrial standard A2 drawings, the main purpose of this new model is to provide a high-angle support frame for the drawing board that can solve the current technical problems, which includes: ：One support frame group; one fixed group, which is a male and female two-clamp fixed block group, with screw holes and fixed clamp holes of the size of the support rod; a non-slip cushion group; a drawing board; a classroom desk; Further, the high-angle support frame for the drawing board as described above, wherein the support frame group is formed by a round iron 3D bending, and one of the support frames is formed by a horizontally abutting long rod to form an abutting surface with the back of the drawing board; there are two The horizontal fixed short rod provides the fixed block of the fixed group as a limit function; there are two supporting long legs as angle support.

Furthermore, the high-angle support frame for the drawing board as described above, wherein the anti-slip pad set has at least two anti-slip pads fixed on the left and right sides of the bottom edge of the drawing board for the purpose of being stuck on the table edge for stability, which is the same as the aforementioned The support frame group forms an appropriate angle.

Furthermore, the high-angle support frame of the drawing board as described above, wherein the fixing block of the fixing group fixes the aforementioned support frame group on the back of the drawing board, at a position of a quarter of the board width from the top edge, And it forms an appropriate angle with the aforementioned anti-slip pad group, which can be called an ideal and stable combination.

Preferably, in the high-angle support frame of the drawing board as described above, the two long supporting legs are covered with supporting foot pads to increase the anti-slip force.

The new model further provides general classroom desks that can be placed A2 enlarged drawing board, parallel ruler, parallel instrument and mechanical drawing machine with drawing function, and the function of teaching and teaching practice. Sweep learning drawing must have a special drawing machine for professional drawing classroom, etc. The concept of expensive equipment.

In order to understand the technical features and practical effects of the present invention in detail, and to implement it in accordance with the content of the specification, the preferred embodiment shown in the figure is further described in detail as follows:

The high-angle support frame for the drawing board provided by the present invention is shown in Figure 3. The iron rod is clamped up and down by the fixing block and fixed on the back of the drawing board with screws about a quarter of the position, and it is against the iron rod and the top edge of the drawing board. The horizontal shape ensures that the two long supporting legs can be pressed against the desktop at the same time to form a stable state.

As shown in Figures 1, 3, 4 and 5, the anti-slip pads are respectively fixed on the lower edge of the drawing board, at the left and right side positions, using multiple concave pads to lean against the edge of the table, the angle of the bevel of the drawing board can be fine-tuned, and the drawing board can be stabilized.

Through the above technical means, the effects obtained by the present invention are increased as follows:

1. As long as the supporting long legs (114) are extended, it is possible to set the drawing board (40) larger than the desk surface (51) on the desk (50), and the drawings of German Industrial Standard A2 can be used , And cover the drawing range of the entire drawing.

2. When storing, as long as the supporting long leg (114) is retracted, it is placed on the back of the drawing board (40) and placed in the same direction as the drawing board (40), which does not take up space and is placed in the storage cabinet.

3. The long rod (111) can also be used as a handle holder for holding the drawing board.

4. The multi-segment concave pad (31) is stuck on the desk edge (52) of the desktop, which fully exerts the function of stabilizing the drawing board (40) and micro-modulating the slope angle of the drawing board (40).
