Description
Technical field
The utility model relates to a kind of music education appurtenance, specifically, relates to a kind of staff chalk and wipes.
Background technology
Chalkboard eraser general is in the market made up of wide strip shell and the hairbrush be fixed in shell, and fix hairbrush by shell, person easy to use clears up blackboard, and does not have other function.In music education, often need to draw staff on blackboard, staff is made up of five parallel lines, expresses concrete music score chapters and sections according to the note be plotted on staff.The drafting of existing staff is all draw one by one on blackboard with long ruler, because lines are longer, to draw skill require higher, slightly crooked namely may cause the mutual spacing of further part five lines change huge, therefore draw staff be the thing that part is wasted time and energy.
Utility model content
The purpose of this utility model is to provide a kind of staff chalk and wipes, and improves, make it have the function of convenient and swift drafting staff concurrently simultaneously to existing chalkboard eraser.
The purpose of this utility model is achieved in that
A kind of staff chalk is wiped, comprise ledge for chalk on blackboard and the hairbrush being fixed on outside, ledge for chalk on blackboard bottom surface, the bottom of described ledge for chalk on blackboard is provided with a up-down adjustment draw runner, described up-down adjustment draw runner is equidistantly provided with five spring card slots, the end face of described ledge for chalk on blackboard is equidistantly provided with five holes, described five holes and described five spring card slot one_to_one corresponding, chalk is vertically fixed in described spring card slot.
Wherein, the described spring card slot side corresponding with described hole is a little more than opposite side, a spring is provided with in lower side, a slide block is provided with between described spring and higher side, a described slide block part extends the below of described hole, and the top that described slide block extends the part below described hole is inclined-plane.
Wherein, described up-down adjustment draw runner comprises the draw runner card that a horizontally disposed fixed mount and can move forward and backward, described draw runner card is provided with latch, moving forward and backward by described draw runner card, described fixed mount can switch between locking state and adjustment state, and described five spring card slots are located on described fixed mount.
Further, described staff chalk is wiped and is also provided with an enclosing cover, and the outer of described ledge for chalk on blackboard end face is arranged with a catching groove agreed with described enclosing cover edge, when using as blackboard eraser, described enclosing cover is covered the end face of ledge for chalk on blackboard by described catching groove, can prevent chalk to make dirty the hand of user.
Further, the outer of the ledge for chalk on blackboard bottom surface that described staff chalk is wiped is arranged with a catching groove agreed with described enclosing cover edge, and when drawing staff, described enclosing cover can be covered hairbrush by described catching groove, person easy to use is hand-held.
The utility model is owing to have employed technique scheme, compared with prior art there is following beneficial effect: the utility model staff chalk is wiped by carrying out structure improvement to existing blackboard eraser, increase with chalkrail structure, the spring card slot of five fixing chalks is set in ledge for chalk on blackboard, and realize carrying out up-down adjustment to the chalk be fixed in spring card slot by up-down adjustment draw runner, both can facilitate and directly draw staff, also can carry out length adjustment according to the service condition of chalk and demand.

Detailed description of the invention
Staff chalk is as shown in Figure 1 wiped, and comprise ledge for chalk on blackboard 1 and the hairbrush 2 being fixed on outside, ledge for chalk on blackboard 1 bottom surface, the bottom of ledge for chalk on blackboard 1 is provided with a up-down adjustment draw runner 3.Up-down adjustment draw runner 3 comprises horizontally disposed fixed mount 31 and the draw runner card 32 that can move forward and backward, draw runner card 32 is provided with latch 321 (shown in Fig. 3), moving forward and backward by draw runner card 32, fixed mount 31 can switch between locking state and adjustment state, and five spring card slots 4 are equidistantly located at (shown in Fig. 2) on fixed mount 31.Accordingly, the end face of ledge for chalk on blackboard 1 is equidistantly provided with five holes, 5, five holes 5 and five spring card slot 4 one_to_one corresponding, and chalk 6 is vertically fixed in spring card slot 4.
Wherein, spring card slot 4 side 41 corresponding with hole 5, a little more than opposite side 42, is provided with a spring 7, is provided with a slide block 8 between spring 7 and higher side 41 in lower side 42, slide block 8 part extends the below of hole 5, and the top that slide block 8 extends the part below hole 8 is inclined-plane 81.Composition graphs 4 and Fig. 5, chalk 6 inserts spring card slot 4 from hole 5, and the inclined-plane 81 of bottom to slide block 8 of chalk 6 acts on, slide block 8 slides to the right, chalk 6 is inserted to the bottom of spring card slot 4, and slide block 8 gives chalk 6 one reaction forces under the effect of spring 7, thus fixes chalk 6.
Latch 321 on draw runner card 32 fixes fixed mount 31, when needing the length regulating chalk 6, pull draw runner card 32, latch 321 is made to leave fixed mount 31, move up and down fixed mount 31 to the height needed, again draw runner card 32 is pushed back to original position, latch 321 retightens fixed mount 31, completes the adjustment of chalk length.
Staff chalk is as shown in Figures 6 and 7 wiped, and its structure is substantially identical with a upper embodiment.As the further improvement of a upper embodiment, the difference of the present embodiment is: in the present embodiment, staff chalk is wiped and is also provided with an enclosing cover 9, the outer of ledge for chalk on blackboard 1 end face is arranged with the catching groove agreed with enclosing cover 9 edge, and the periphery of ledge for chalk on blackboard 1 bottom surface is also provided with the catching groove agreed with enclosing cover 9 edge simultaneously.When using as blackboard eraser, described enclosing cover 9 is covered the end face of ledge for chalk on blackboard 1 by catching groove, can prevent chalk 6 to make dirty the hand (Fig. 7) of user; When drawing staff, described enclosing cover can be covered hairbrush by described catching groove, person easy to use hand-held (Fig. 6).
Certainly, singly only have the catching groove being arranged with outside the bottom surface of ledge for chalk on blackboard 1 or end face and agreeing with enclosing cover 9 edge, also do not affect enforcement of the present utility model, and belong to the utility model scope required for protection.
