Description

Multipurpose blackboard scriber

Technical field

The utility model relates to the school supply and stationery technical field, especially a kind of teaching blackboard and servicing unit thereof.

Background technology

The blackboard of the usefulness of imparting knowledge to students in the past, when the teacher strikes flat line or vertical straight line thereon, often need can finish the line operation by means of ruler or bigger wooden set square, do the trouble completely that seems like this, sometimes also can straight line be drawn partially because putting not positive ruler, particularly when drawing form, influence bigger.There is the people to make various improvement at the above-mentioned shortcoming that traditional blackboard exists for this reason, as State Intellectual Property Office's bulletin on November 14th, 2007, the patent No. is 200620154227.2, the utility model patent that is called " a kind of blackboard " by the name of Yang Yingjuan design is exactly innovation and creation preferably, it mainly is respectively to be provided with a guider at four lateral location places of blackboard main body, be provided with a horizon bar line between two guiders of vertical direction, the horizon bar line can stop at an arbitrary position, be provided with a vertical bar line between two guiders of horizontal direction, vertical bar line can stop at an arbitrary position.Four sides of blackboard main body are provided with housing, guider is installed on the housing, four sides of blackboard main body are provided with housing, guider is installed on the housing, be provided with a horizon bar line between two guiders of vertical direction, the horizon bar line can stop at an arbitrary position, is provided with a vertical bar line between two guiders of horizontal direction, vertical bar line can stop at an arbitrary position, can draw form by mobile and horizontal bar line and vertical bar line like this; Its shortcoming is once to draw a line, and is still very inconvenient for the music teacher draws staff.And in order on blackboard, to draw staff, someone has designed quick scriber, as State Intellectual Property Office on February 20th, 2002 bulletin, the patent No. is 01202869.X, the utility model patent that is called " scriber fast " by the name of longevity tinkle design is exactly innovation and creation preferably, it mainly by the pedestal of band ambulatory splint, place length adjustment device in the pedestal etc. to constitute, length adjustment device front end in the pedestal is provided with ledge for chalk on blackboard, and ledge for chalk on blackboard can be set to a plurality of; During use, chalk is placed in the ledge for chalk on blackboard in the pedestal, in the afterbody embedded length adjusting device of chalk, portable plate closes, grasp pedestal and can on blackboard, mark the required staff of teaching, four line lattice etc. easily and quickly, spacing between line and the line can be consistent, and its shortcoming is that five lines of staff guarantee with respect to the depth of parallelism of the frame of blackboard is still very difficult, can only lean on teacher's setting-out skill to decide.

Summary of the invention

The purpose of this utility model is to provide a kind of easy to use, staff five lines that can draw fast, can also doublely makees the multipurpose blackboard scriber of other teaching drawing tools on blackboard.

The technical scheme that the utility model is adopted for achieving the above object is:

A kind of multipurpose blackboard scriber, comprise the blackboard main body that has frame, its special character is to be provided with guide rail between the upper side frame, lower frame of described blackboard main body, and being connected with on the guide rail can be along the setting-out module of its slip, the setting-out module is provided with the shaft of a writing brush, and a tool inserts wherein; Guide rail is provided with guide-track groove, and the described shaft of a writing brush can pass in this guide-track groove; Guide rail can slide along upper side frame, the lower frame of blackboard main body.

Regulate for convenience, described shaft of a writing brush upper end is provided with gland, is provided with spring in the gland, is threaded between gland and the shaft of a writing brush; After using the certain phase chalk to be worn, can rotate gland and make chalk produce suitable pressure the space of a whole page of blackboard main body, make setting-out convenient, clear.

Light in order to use, laborsaving, described guide rail top and bottom are respectively equipped with roller, and roller can roll along upper side frame, the lower frame of blackboard main body.

Regulate for convenience, described setting-out module is provided with dog screw.

Select for the convenience of the users, the described shaft of a writing brush is 5, can use 5 shafts of a writing brush simultaneously when music teacher draws staff; Then can only use 4 shafts of a writing brush wherein when the English teacher draws four line lattice, math teacher then may only use 1 shaft of a writing brush wherein.

Multipurpose blackboard scriber of the present utility model in use, earlier chalk is inserted in a plurality of shafts of a writing brush that are provided with on the setting-out module, again with on the gland connection and the shaft of a writing brush, hand-held setting-out module drives the guide rail side-to-side movement, the parallel straight line that can on blackboard, draw, have be easy to regulate, the convenient advantage of using.
