Description

Anti-bias skewing scheme plate and T-square tackling

Technical field

The utility model relates to a kind of drafting instrument, specifically a kind of anti-bias skewing scheme plate and T-square tackling.

Background technology

When the drawing course study of colleges and universities, chart board and T-square are indispensable drafting instruments, the chart board using mostly now is ganoid hollow plank, not yielding, comparatively light, T-square is comprised of chi plate and sliding plate, chi plate and sliding plate are two parts, sliding plate is adhesively fixed on chi plate one end, in the time of in use, there is bonding phenomenon not firm and that come off to occur, sliding plate is parallel bonding with chi plate, the large surface of sliding plate does not contact with chart board, just side contacts with chart board and slippage, so T-square area occupied outside chart board is larger while using, to use, make troubles, in addition, in drawing study course, the drawing that T-square has relatively been fixed on chart board is easily offset left, our mapping benchmark is offset, institute's size of painting and switch generation error or mistake, original T-square should horizontal placing flat, sometimes in drawing course, also T-square deflection can occur, and T-square is not horizontal flat, will affect being parallel to each other or the relation of vertical or angle of painted view lines.

Summary of the invention

The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, provide a kind of and can prevent that T-square from anti-bias skewing scheme plate and T-square tackling inclined to one side or oblique, simple in structure occurring.

The technical scheme that the utility model adopts is: anti-bias skewing scheme plate and T-square tackling, it comprises chart board and T-square, chi plate and the sliding plate of T-square are connected as a single entity, chi plate surface arranges size indication, sliding plate, perpendicular to the surface at size indication place, is characterized in that: two adjacent side of described chart board are the baffle plate of fixed L shape respectively.

The baffle plate end face of described baffle plate is lower than chart board working face.

The width of described baffle plate and chart board groove that side forms equals the thickness of sliding plate.

The length of described baffle plate is less than or equal to the length of corresponding chart board side.

The beneficial effects of the utility model are: 1, the baffle plate of two of chart board adjacent side difference fixed L shapes, in drawing course, prevent that the drawing that T-square has relatively been fixed on chart board is offset left, prevent that T-square generation deflection, the not horizontal flat phenomenon of T-square from occurring.2, the baffle plate end face of baffle plate is lower than picture plate working face, make sliding plate above one section can expose, facilitate illustrator to operate sliding plate and carry out slippage, mapping.

Fig. 2 is T-square schematic perspective view of the present utility model.

Fig. 3 is the schematic perspective view of chart board of the present utility model and baffle plate.

The specific embodiment

As shown in Figure 1 to Figure 3, it comprises chart board (1) and T-square (2) the present embodiment, and the chi plate (3) of T-square (2) is connected as a single entity with sliding plate (4), makes the manufacture of T-square 2 more easy, save cost, also improved the bonding strength of 4 of chi plate 3 and sliding plates; Chi plate (3) surface arranges size indication (5), sliding plate (4) is perpendicular to the surface at size indication (5) place, when using the present embodiment, make the left surface of the large surface laminating chart board 1 of sliding plate 4 carry out slippage, reduced the overall dimensions of T-square 2, make the overall dimensions of chart board 1 and T-square 2 less, carry and deposit more convenient; Two adjacent side of described chart board (1) are the baffle plate (6) of fixed L shape respectively, baffle plate (6) equals the thickness of sliding plate (4) with chart board (1) width of groove that side forms, in drawing course, the sliding plate 4 of T-square (2) snaps in baffle plate (6) and forms in groove with chart board (1) side, prevent that the relative drawing that has been fixed on chart board 1 of T-square 2 is offset left, prevent that T-square 2 from deflections occurring, the not horizontal flat phenomenon of T-square 2 occurs; The baffle plate end face (7) of baffle plate (6) is lower than chart board working face (8), make sliding plate (4) above one section can expose, facilitate illustrator to operate sliding plate (4) and carry out slippage, mapping; The length of baffle plate (6) is less than or equal to the length of corresponding chart board (1) side, and when using T-square (2) to draw the top or bottom lines, sliding plate (4) can some stretch out chart board, is unlikely to be stopped by another baffle plate (6).

If while drawing the horizontal view of placing of drawing, the sliding plate (4) of T-square (2) snaps in baffle plate (6) and forms in groove with limit, chart board (1) left side, and operation sliding plate (4) carries out slippage, can map; If while drawing the longitudinal view of placing of drawing, chart board (1) rotates counterclockwise 90 degree, the sliding plate (4) of T-square (2) snaps in baffle plate (6) and forms in groove with limit, chart board (1) left side, and operation sliding plate (4) carries out slippage, can map.

The utility model is suitable for colleges and universities' drawing classroom uses, and the drawing classroom that is suitable for middle school is used, and is also suitable for enterprises and institutions' drawing and uses.
