Abstract
The utility model relates to a portable drawing board, which comprises a board frame of which the periphery is provided with a groove, a panel attached to the board frame and a parallel rule arranged on the board frame, wherein, one end of the parallel rule is provided with a guide claw which is clamped in the groove of the board frame; an eccentric wheel and a knob which can make the parallel rule positioned are arranged on the parallel rule; the peripheral part of the board frame is also provided with an elastic paper clamping mechanism; consequently, the utility model has convenient use and carrying and precise positioning.
Description
The utility model belongs to the drawing board technical field.
Existing portable drawing board, chart board separates with T-square, and drawing will be fixed with adhesive tape or drawing pin, and using to carry all has inconvenience, and the not protection of working face that contact with chart board of T-square, and damage is out of shape easily, influences the drawing accuracy.
The purpose of this utility model be design a kind ofly carry, easy to use, the drawing board that the drawing accuracy is high.
For achieving the above object, the utility model is fitted with panel at the middle part of the upper surface of grillage, parallel rule is housed on grillage, the periphery of grillage has recessed groove, be fixed with below one end of parallel rule and be installed in this groove slidably guide grab, thereby the edge also is housed below this end parallel rule can holds out against the eccentric wheel that on guide grab, makes the parallel rule location, the knob of the driven eccentric wheel rotation of fixing by screw and eccentric wheel is arranged above the parallel rule.
The utility model has several grooves in the edge of grillage, has elasticity holding paper mechanism in the groove, Yi Bian the supporting plate that this holding paper mechanism is extended by grillage, to be installed in the spring below the supporting plate and to be pressed on cross sectional shape on the supporting plate under spring action be that the pressing plate of shape constitutes.
The utility model parallel rule and chart board are installed together, and portably use conveniently, and the location accurately, and is not fragile, and has holding paper mechanism, during use chart board and drawing all do not caused damage.
Below in conjunction with accompanying drawing structure of the present utility model is described further.
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is the B-B cutaway view among Fig. 1;
Fig. 3 is the A-A cutaway view among Fig. 1.
Grillage of the present utility model (1) is a rib structure, by the plastics single injection-molded.The middle part of grillage (1) upper surface is fitted with the panel (5) of calcic-plastic composite material.Periphery bit strip at grillage (1) has recessed groove (2), has the guide grab (9) that can slide along groove that is clamped in the grillage groove (2) below the end of parallel rule.Below this end parallel rule (6), an eccentric wheel (10) is arranged, it is fixed together by the top knob (7) of screw (11) and parallel rule (6), during turning knob (7), the edge of eccentric wheel (10) can hold out against on guide grab (9), thereby make parallel rule (6) fixing, realize the location.Also have three grooves in the edge of grillage (1), flexible holding paper mechanism in the groove, this mechanism is by the extended supporting plate of grillage (1) (12), be installed in the following spring (13) of supporting plate (12), and the cross sectional shape that is pressed on one side under spring (13) effect on the supporting plate (12) is pressing plate (3) formation of shape, the outside of pressing plate (3), its inner edge just can rise by wing, after the drawing edge put into its relieving, under the effect of spring (13), drawing can be compressed, on two adjacent limits of grillage (1), can have scribe mark (4), on parallel rule, also can have engineer's scale and protractor scale (8), thereby use more convenient.Bottom margin at grillage (1) can be equipped with a plurality of rubber foots (14).
