The parallel line drawer is characterized in that a slide board is connected to the bottom of the base board, a slide way is arranged on the surface of the slide board connected with the base board, a slider is correspondingly fixed onto the bottom face of the base board and can slide in the slide way, the slide board consists of small slide boards connected through hinges, partition boards are disposed inside rubber pencil sleeves, springs are connected between the bottoms of the partition boards and the rubber pencil sleeves, the springs are compressed, and the distance between the partition boards and rubber pencil sleeve openings is at least half of the length of the rubber sleeves. The parallel line drawer is simple in structure and convenient in use, can complete drawing of parallel lines through simple operation, can draw out parallel lines with fine parallelism and uniform thickness, facilitates development of English teaching work, saves time and labor, and increases teaching efficiency.
Description
Technical field
The utility model relates to a kind of teaching aid, a kind of specifically English teaching parallel lines scriber.
Background technology
In English teaching, carrying out for the ease of teaching, the teacher need draw many parallel lines usually on blackboard, the method for drawing parallel lines at present generally is that the teacher utilizes ruler four lines that draw successively on blackboard, utilizes the personal experience to guarantee to be parallel to each other between each bar line.Inhomogeneous by the parallel lines thickness that said method draws, the depth of parallelism is poor, is difficult to reach code requirement; In addition, use said method setting-out speed slow and the time effort, reduced efficiency of teaching.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, be easy to carry, utilize this scriber many parallel lines that can draw simply, and the parallel lines depth of parallelism of drawing be good, the carrying out that the teaching of utilizing is arranged, the English teaching parallel lines scriber of raising efficiency of teaching.
In order to reach above purpose, the technical scheme that the utility model adopted is: a kind of English teaching parallel lines scriber, comprise substrate, be fixed with handle on the lateral surface of described substrate, its short transverse fixed interval of medial surface upper edge of corresponding substrate is provided with the rubber pen cap, in the rubber pen cap chalk is housed, wherein, the bottom of substrate is connected with slide plate, the surface that slide plate is connected with substrate is provided with slideway, corresponding substrate bottom surface is fixed with slide block, slide block can slide in slideway, in the rubber pen cap dividing plate is set, and is connected with spring between the bottom of the dividing plate and the rubber pen cap, spring is in confined state, and the distance between dividing plate and the rubber pen cap opening is at least 1/2 of rubber sleeve length.
The utility model is also implemented by following measure: the shape of cross section of described slide plate sliding way is inverse-T-shaped, and the shape of cross section of corresponding base plate bottom slide block is inverse-T-shaped.
The shape of cross section of described slide plate sliding way is a swallow-tail form, and the shape of cross section of corresponding base plate bottom projection is a swallow-tail form.
Described slide plate is formed by connecting by hinge, and is collapsible.
Described handle and substrate are integral structure.
Described slide block and substrate are integral structure.
The beneficial effects of the utility model are: this parallel lines scriber is simple in structure, easy to use, can finish the drafting of parallel lines by shirtsleeve operation, and the parallel lines depth of parallelism of drawing out is good, and even thickness is convenient to carrying out in English teaching work, time saving and energy saving, improved efficiency of teaching.
Description of drawings
Fig. 1 is a structural front view of the present utility model;
Fig. 2 is that the utility model is along the A-A cross-sectional schematic among Fig. 1.
The specific embodiment
Make the utility model with reference to accompanying drawing 1,2.This English teaching parallel lines scriber, comprise slide plate 1 and substrate 2, slide plate 1 is formed by connecting by hinge 4 by three sections small slide plates, between each section small slide plate for being rotatably connected, therefore slide plate 1 is a folding, during use each section small slide plate is launched, when not using that each section small slide plate is folding, be convenient to take in and carry; Slide plate 1 is arranged on the bottom of substrate 2, slide plate 1 is provided with slideway with the surface that substrate 2 is connected, the bottom surface of counterpart substrate 2 is fixed with slide block 7, described inverse-T-shaped slide block 7 is integral structure with substrate 2, the shape of cross section of slideway is for falling " T " OK, and the interface shape of corresponding slide block 7 also is inverse-T-shaped; Inverse-T-shaped slide block 7 can slide in inverse-T-shaped slideway, slides along slide plate 1 thereby drive substrate 2; The lateral surface of substrate 2 is fixed with handle 3, and for the ease of holding, handle 3 is cylindrical, and handle 3 is integral structure with substrate 2; Its short transverse of medial surface upper edge of corresponding substrate 2 is provided with four rubber pens cap 5 successively at interval, the rubber pen cap 5 is fixed on the substrate 2, dividing plate 9 is set in the rubber pen cap 5, be connected with spring 6 between the bottom of the dividing plate 9 and the rubber pen cap 5, spring 6 is in confined state all the time, and spring 6 can drive the inwall slip of dividing plate 9 along the rubber pen cap 5; For chalk 8 can be placed in the rubber pen cap 5, the distance when being in duty not between dividing plate 9 and the rubber sleeve opening is at least 1/2 of rubber sleeve length.
When the utility model uses, slide plate 1 is launched, substrate 2 is adjusted to an end of slide plate 1, chalk 8 is packed in the rubber pen cap 5 by hinge 4.The length difference of chalk owing to pack into, hold handle 3 during setting-out, and substrate 2 applied a pressure, promptly this pressure is parallel to the axis direction of handle 3, the chalk top contacts with blackboard simultaneously, chalk 8 between blackboard and the substrate 2 is squeezed, the spring 6 of the rubber of the afterbody of chalk extruding at this moment pen cap inside, and spring 6 compressions make the head of chalk 8 concordant.Moving handle 3 makes substrate 2 slide into the other end of slide plate 1 along slideway then, and by contacting of chalk 8 and blackboard, four parallel lines equably draw on blackboard.After using end chalk 8 is taken out in the rubber pen cap 5, make slide plate 1 folding, be easy to carry along hinge 4.
In the utility model, the length of slide plate 1 is set according to actual operating position, and its segmentation also is not limited to three sections in the present embodiment, also can be divided into two sections or multistage more; The shape of slide plate 1 sliding way also is not limited to inverse-T-shaped in the present embodiment, also can be swallow-tail form or wedge shape, as long as can serve the same role; In addition, the rubber pen cap of other quantity can be set also on the substrate 2, be not limited to four rubber sleeves in the present embodiment; Described hinge also can be replaced by the rotary connector that hinge etc. plays same function.
This English teaching parallel lines scriber, simple in structure, easy to use, the parallel lines that draw are even and the depth of parallelism good, are easy to carry, and are highly suitable for English teaching.
