The disclosed name by longevity Ding Dong design of State Intellectual Property Office is called that " quick line drawing device " is good innovation and creation; it is primarily of the formation such as pedestal, the length adjustment device be placed in pedestal of band ambulatory splint; length adjustment device front end in pedestal is provided with ledge for chalk on blackboard, and ledge for chalk on blackboard can be set to multiple; During use, chalk is placed in the ledge for chalk on blackboard in pedestal, in the afterbody embedded length adjusting device of chalk, close portable plate, grasp pedestal on blackboard, staff, four line lattice etc. needed for teaching can be marked easily and quickly, spacing between the lines can be consistent, and its shortcoming is that five lines of staff are still difficult to ensure relative to the depth of parallelism of the frame of blackboard, and the setting-out skill of teacher can only be leaned on to have decided.
But above-mentioned line tool and traditional line tool all just possess single setting-out function.
Summary of the invention
Technical purpose of the present utility model is for problems of the prior art, provide a kind of can as the instrument wiping chalk dust of blackboard brush, simultaneously again can the instrument of setting-out.
The technical solution of the utility model is:
A kind of new type blackboard, left side and the right side of described blackboard have chute, described blackboard is provided with setting-out panel, described setting-out panel has slide fastener, described slide fastener matches with described chute, described setting-out panel can slide on described blackboard, and the upper and lower two ends of described blackboard have stopping means; Described setting-out panel comprises outside plate and dust exhaust apparatus, scale is provided with on the upside of described outside plate, lower scale is provided with on the downside of described outside plate, described setting-out panel also has hinge means and adjusting rod, described hinge means is installed between outside plate and dust exhaust apparatus, described adjusting rod connecting hinge chain apparatus, regulates the distance of dust exhaust apparatus and blackboard writing panel by adjusting rod.
Described dust exhaust apparatus is removably installed on setting-out panel, and described dust exhaust apparatus is rectangular cavernous body, and the length of described blackboard is 3m-4m, and the width of described blackboard is 1m-2m, and described blackboard lower end has powder groove, and described powder groove is circular arc.Described blackboard upper end is also provided with projection screen.Described blackboard also has arrangement for adjusting height, and when writing, the height of adjustable blackboard is so that write, and described arrangement for adjusting height is slip railroad.
Accompanying drawing explanation
Fig. 1 is for being structural representation of the present utility model.
Fig. 2 is transverse sectional view of the present utility model.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is further illustrated.Wherein, accompanying drawing only for exemplary illustration, expression be only schematic diagram, but not pictorial diagram, can not be interpreted as the restriction to this patent; In order to better embodiments of the invention are described, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; For a person skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.
The corresponding same or analogous parts of same or analogous label in the accompanying drawing of the embodiment of the present invention, in describing the invention, it will be appreciated that, if have term " on ", D score, " left side ", orientation or the position relationship of the instruction such as " right side " are based on orientation shown in the drawings or position relationship, only the present invention for convenience of description and simplified characterization, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore the term of position relationship is described only for exemplary illustration in accompanying drawing, the restriction to this patent can not be interpreted as, for the ordinary skill in the art, the concrete meaning of above-mentioned term can be understood as the case may be.
As Fig. 1 to 2 is depicted as the embodiment of a kind of new type blackboard of the utility model, the left side of blackboard and right side have chute 12, blackboard is provided with setting-out panel 2, setting-out panel 2 has slide fastener 22, slide fastener 22 matches with chute 12, setting-out panel 2 can slide on blackboard, and the upper and lower two ends of blackboard have stopping means 15; Setting-out panel 2 comprises outside plate 21 and dust exhaust apparatus 5, scale 26 is provided with on the upside of outside plate 21, lower scale 23 is provided with on the downside of outside plate 21, setting-out panel 2 also has hinge means 3 and adjusting rod 4, hinge means is installed between outside plate 21 and dust exhaust apparatus 5, adjusting rod 4 connecting hinge chain apparatus 3, regulates the distance of dust exhaust apparatus 5 and blackboard writing panel by adjusting rod 4.
Dust exhaust apparatus 5 is removably installed on setting-out panel 2, and dust exhaust apparatus 5 is rectangular cavernous body, and the length of blackboard is 3m-4m, and the width of blackboard is 1m-2m, and blackboard lower end has powder groove, and powder groove is circular arc.Blackboard upper end is also provided with projection screen 8.Blackboard also has arrangement for adjusting height, and when writing, the height of adjustable blackboard is so that write, and arrangement for adjusting height is slip railroad.
When setting-out panel needs to be in striping jobs state, handle adjusting rod rotational hinge means and dust exhaust apparatus is separated with blackboard panel, then make the letter written with chalk can not wiped on blackboard panel due to dust exhaust apparatus and the noncontact of blackboard panel during setting-out.When needs blackboard wiping, only need handle adjusting rod and dust exhaust apparatus and blackboard panel are close to, then wipe the chalk trace on blackboard panel.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
