Description
Technical field
It the utility model is related to scriber technical field, more particularly to a kind of marker used for English teaching.
Background technology
In English teaching, to make letter writing standardization, it is often necessary to the lattice of four line three are drawn on blackboard, teacher is painted with ruler
System, not only bad grasp distance reaches expected and draws effect, and repeats to rule, very cumbersome, wastes time and energy, meanwhile, when needing
When writing again, it is also necessary to wipe the content write before with blackboard eraser, virtually improve faculty load.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and a kind of English teaching proposed is used
Scriber.
To achieve these goals, the utility model employs following technical scheme：
A kind of marker used for English teaching, including sliding block, sliding block are provided with sliding mouth, it is sliding it is intraoral be provided with the second straight-bar, second
The side of straight-bar is arranged with sucker, and the both sides of the sliding block are rotatably connected to two symmetrically arranged first straight-bars, two institutes
The side for stating the first straight-bar is rotatably connected to the second belt wheel, and the inwall of the sliding mouth is respectively equipped with the first mounting groove and the second peace
Tankage, the inwall of first mounting groove are rotatably connected to rotating shaft, fixedly sleeved respectively in the rotating shaft to have gear and first band
Wheel, the first pulley and two the second belt wheels are provided with what is be meshed with gear by cleaning band connection, second straight-bar
Rack, the inwall of second mounting groove are rotatably connected to roller, two placements are respectively provided with two first straight-bars
Groove.
Preferably, the inner bottom part of the standing groove is connected with mounting box by spring, and the inwall of the mounting box is provided with admittedly
Determine block.
Preferably, the number of the fixed block is at least three, and multiple fixed block equidistantly distributeds.
Preferably, the fixed block is in a rectangular trapezoid.
Preferably, second straight-bar is provided with level meter close to the side of roller.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, during line, by powder
Penholder enters in mounting box, and the second straight-bar is fixed on blackboard by sucker, and then sliding slider, starts to rule, due to sliding
Sliding block can complete the drafting of four lines, avoid repeating to rule, improve efficiency of teaching, when sliding block moves, gear passes through
Engaged with rack and drive first pulley to rotate, first pulley drives cleaning band to rotate, by the writing in front of sliding block motion track
Appearance is wiped, it is not necessary to is wiped in addition using blackboard eraser, is improved line efficiency.
Brief description of the drawings
Fig. 1 be the utility model proposes structural representation；
Fig. 2 is standing groove part-structure schematic diagram；
Fig. 3 is the top view of mounting box.
In figure：1 first straight-bar, 2 gears, 3 rollers, 4 standing grooves, 5 cleaning bands, 6 first pulleys, 7 sliding blocks, 8 second belt wheels,
9 racks, 10 second straight-bars, 11 suckers, 12 springs, 13 mounting boxs, 14 fixed blocks, 15 level meters.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.
Reference picture 1-3, a kind of marker used for English teaching, including sliding block 7, sliding block 7 are provided with sliding mouth, sliding intraoral to be provided with the
Two straight-bars 10, the side of the second straight-bar 10 are arranged with sucker 11, and the both sides of sliding block 7 are rotatably connected to two symmetrically arranged
One straight-bar 1, the side of two the first straight-bars 1 are rotatably connected to the second belt wheel 8, and the inwall of sliding mouth is respectively equipped with the first mounting groove
With the second mounting groove, the inwall of the first mounting groove is rotatably connected to rotating shaft, fixedly sleeved respectively in rotating shaft to have gear 2 and first band
Wheel 6, first pulley 6 and two the second belt wheels 8 are connected by cleaning band 5, and the second straight-bar 10 is provided with the tooth being meshed with gear 2
Bar 9.
The inwall of second mounting groove is rotatably connected to roller 3, and two standing grooves 4 are respectively provided with two the first straight-bars 1,
The inner bottom part of standing groove 4 is connected with mounting box 13 by spring 12, and the inwall of mounting box 13 is provided with fixed block 14, fixed block 14
Number is at least three, and the equidistantly distributed of multiple fixed blocks 14, and fixed block 14 is in a rectangular trapezoid, and the second straight-bar 10 is close to roller
3 side is provided with level meter 15, is easy to observe whether the second straight-bar 10 is horizontal.
Operation principle：During line, chalk is inserted in mounting box 13, the second straight-bar is fixed on blackboard by sucker,
Now, can be by observing level meter 15, whether the second straight-bar 10 of judgement is horizontally situated, and then sliding slider, starts to rule,
Even if occurs the situation of chalk abrasion in the process, because spring 12 acts on mounting box 13, it is ensured that chalk and blackboard
Contact dynamics, make the vestige of line obvious, because the drafting of four lines can be completed by sliding a sliding block 7, can avoid repeating to rule,
