Description
Technical field
The utility model relates to a kind of English-teaching aid, especially a kind of blackboard line apparatus of English teaching.
Background technology
As everyone knows, the standard format write of English writes in four line lattice.Serve as a teacher and stand in when dais teaches English; in order to better show writing of English; often can use four line lattice writing class hour; it is all adopt ruler to draw four lines respectively that present teachers draws four line lattice, and do not have special tool scribe line, the line so not only drawn is irregular; efficiency is not high; waste valuable instructional blocks of time, the notice of student is also easily disperseed, unfavorable to teaching.
Summary of the invention
The blackboard line apparatus of the English teaching of a kind of adjustable four line compartment distances that the purpose of this utility model is deficiency in order to solve above-mentioned technology and designs.
The blackboard line apparatus of a kind of English teaching designed by the utility model, comprise a cabinet shape frame, the horizontal stripe of cabinet shape frame upper end is provided with hand operated portion, the horizontal stripe of described cabinet shape frame lower end is provided with four chalk fixer, described chalk fixer is made up of body, lid, spring leaf, augering screw and stator, described lid is screwed onto body top, and described spring leaf is located at the mouth of pipe place of body and is multiple; Described augering screw, through lid, is provided with the chalk holddown groove for slotting chalk bottom augering screw; Described stator is connected to body side, and described stator longitudinal section is U-shaped, and the horizontal stripe of described cabinet shape frame lower end is stuck in described stator, described stator is also provided with hand and twists lock-screw; The horizontal stripe of described cabinet shape frame lower end is provided with scale.
As preferably: described spring leaf is two, left and right, or described spring leaf is in 90 degree four spaced apart.
The blackboard line apparatus of the English teaching designed by the utility model, chalk is contained in the chalk fixer of this device, and teacher can utilize this device on blackboard, mark four impartial line lattice of distance easily.In the middle of the process that reality uses, can regulate the spacing of four line lattice as required, convenient and swift, effectively can improve efficiency of teaching, be particularly suitable for traditional black board teaching.
Accompanying drawing explanation
Fig. 1 is the structural representation of the blackboard line apparatus of embodiment 1 English teaching.
Fig. 2 is the side view of the blackboard line apparatus of embodiment 1 English teaching;
Fig. 3 is the enlarged drawing at A place in Fig. 1.
In figure: cabinet shape frame 1, hand operated portion 2, horizontal stripe 3, chalk fixer 4, body 5, lid 6, spring leaf 7, augering screw 8, stator 9, hand twist lock-screw 10, scale 11, chalk holddown groove 12, chalk 13.
Detailed description of the invention
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1:
As shown in Figure 1, 2, 3, the blackboard line apparatus of the English teaching described by the present embodiment, comprise a cabinet shape frame 1, the horizontal stripe of cabinet shape frame 1 upper end is provided with hand operated portion 2, the horizontal stripe 3 of described cabinet shape frame 1 lower end is provided with four chalk fixer 4, described chalk fixer 4 is made up of body 5, lid 6, spring leaf 7, augering screw 8 and stator 9, and described lid 6 is screwed onto body 5 top, and described spring leaf 7 is located at the mouth of pipe place of body 5; Described spring leaf 7 is two, left and right, and described augering screw 8, through lid 6, is provided with the chalk holddown groove 12 for slotting chalk 13 bottom augering screw 8; Described stator 9 is connected to body 5 side, and described stator 9 longitudinal section is U-shaped, and the horizontal stripe 3 of described cabinet shape frame 1 lower end is stuck in described stator 9, described stator 9 is also provided with hand and twists lock-screw 10; The horizontal stripe 3 of described cabinet shape frame 1 lower end is provided with scale 11.
The blackboard line apparatus of this English teaching, chalk 13 is contained in the body 5 of chalk fixer 4, and chalk 13 top is fixed in chalk holddown groove 12, chalk holddown groove 12 top is firmly withstood by screw rod 8, like this in scratching process, chalk 13 would not bounce back, and can rule normally; After chalk 13 uses a period of time to have consumption, according to service condition, augering screw 8 can be turned downwards, chalk holddown groove 12 can be ejected downwards, thus the relative position adjusted between different chalk end, guarantee that the chalk head of its four chalks is on same level line; Two, the left and right spring leaf 7 of body 5 oral area effectively can eliminate the gap between chalk 13 and body 5 oral area, and slowly walks downward along with chalk 13, and spring leaf can swell along with the increase of chalk 13 bore, guarantees that chalk 13 can normally be stretched.Horizontal stripe 3 is stuck in described stator 9, and chalk fixer 4 is connected with horizontal stripe 3 by stator 9, and hand is twisted lock-screw 10 and is pressed on horizontal stripe 3 by stator 9.The horizontal stripe 3 of cabinet shape frame 1 lower end is provided with scale 11, can find out the distance between chalk fixer 4 intuitively; When need regulate the distance of four line lattice according to the size of blackboard, hand can be loosened and twist lock-screw 10 with mobile chalk fixer 4, and according to the scale 11 on horizontal stripe 3, determine that its spacing is to adjust, convenient directly perceived and the spacing of four line lattice can accurately be ensured.
This blackboard line apparatus, chalk is contained in the chalk fixer of this device, and teacher can utilize this device on blackboard, mark four impartial line lattice of distance easily.In the middle of the process that reality uses, can regulate the spacing of four line lattice as required, convenient and swift, effectively can improve efficiency of teaching, be particularly suitable for traditional black board teaching.
Embodiment 2
The blackboard line apparatus of the English teaching described by the present embodiment; as different from Example 1: described spring leaf is in 90 degree four spaced apart; four spring leafs can better be fixed chalk from multiple angle and protect chalk not easy fracture, more handy when this device of use.
In fact, spring leaf described in above-mentioned two embodiments can be the uniform existing way of more even numbers, can play the effect of fixing chalk and protection chalk not easy fracture.
Specific embodiment described herein is only to design of the present utility model explanation for example.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
