Description

A kind of Portable English teaching device

Technical field

The utility model relates to teaching aid technical field, specially a kind of Portable English teaching device.

Background technique

Listening, speaking, reading and writing is four aspects of English study, and " writing " is usually the order of strokes observed in calligraphy and letter according to letter in English study The position that should be accounted in four lines, three lattice is write, and therefore, teacher needs first to draw out four to be parallel to each other when carrying out classroom instruction Horizontal line, then carry out writing demonstration, with the good writing style of training student, and teacher when drawing four lines usually by ruler Secondary scribe, but ruler or volume are larger, Portable belt or limited length, cannot not complete drawing for longer lines once System, and segmentation drafting both unsightly and had been difficult to ensure that four lines were parallel to each other, can also upset teaching rhythm, influence teaching efficiency.

Utility model content

It is inconvenient to carry using ruler secondary scribe for teachers ' teaching, cannot disposably draw long line, scribing line unsightly with And the shortcomings that influencing teaching efficiency, the utility model provides a kind of Portable English teaching device, and it is small in size, conveniently take Band can disposably complete the drafting of longer lines, effectively improve teaching efficiency, can also draw short-term, applied widely.

The utility model adopts the following technical solution: it includes pedestal, it is characterised in that: is provided at the top of the pedestal recessed Slot, the groove are provided with liner agency, and the liner agency includes sliding block, and chalk clamp, which is shelved, is rotationally connected with institute by shaft Sliding block is stated, the sliding block is flush-mounted in the groove, and the chalk clamp, which is shelved, clamps hole equipped with chalk.

It is further characterized by:

The chalk, which clamps, is equipped with flat spring in hole；

The chalk clamp hole at least there are four and spaced set；

In the top of the shaft and the sliding block junction, arc limit slot, the arc are provided on the sliding block The groove face of limiting slot is the flank of tooth, and the chalk clamp, which is shelved, is fitted with support shaft on the end face of that side of sliding block combination, The support shaft rolling is installed in the arc limit slot；

The two sides of the sliding block are equipped with boss, and the sliding block is flush-mounted in the groove by the boss；

The pedestal is cuboid pedestal, is bonded with felt cloth, edge along the side of the cuboid pedestal length direction The side of width direction, internal hollow out, the hollow out position are provided with articles ride room, the clamping of articles ride ceiling portion Door, bottom have family equipped with magnet.

After adopting the above structure, chalk by chalk clamps hole and is fixed on chalk clamp to be shelved the utility model, rotates powder Pen clip is shelved to certain position, and mobile sliding block, which can draw short-term or mobile foundation, can disposably complete longer lines, is fitted It is wide with range, and teaching efficiency can be effectively improved, when not in use, chalk clamp can be shelved rotation and collapsed in groove, it is small in size, It is easy to carry.

Specific embodiment

The utility model will be further described below with reference to the accompanying drawings:

As shown in Fig. 1 ~ 4, the utility model provides a kind of Portable English teaching device comprising pedestal 1, pedestal 1 Top is provided with groove 5, and groove 5 is provided with liner agency, and liner agency includes sliding block 2, and chalk clamp is shelved 3 and rotated by shaft 10 It is connected to sliding block 2, sliding block 2 is flush-mounted in groove 5, and chalk clamp shelves 3 and clamps hole 4 equipped with chalk, and chalk clamps hole by chalk It is fixed on chalk clamp to shelve, rotation chalk clamp is shelved to certain position, and mobile sliding block can draw short-term or mobile foundation Longer lines can be disposably completed, it is applied widely, and teaching efficiency can be effectively improved, when not in use, chalk can be clamped Frame rotation collapses in groove, small in size, easy to carry.

As shown in figure 3, chalk, which clamps, is equipped with flat spring 12 in hole 4, chalk can be both fastened, it can also be when force draws four lines Chalk is prevented to be broken；As shown in Figure 1, chalk clamp hole at least there are four and spaced set, can disposably complete four lines, three lattice Drafting, facilitate the drafting of line lattice, further increase teaching efficiency.

As illustrated in fig. 1 and 2, arc limit slot 8, arc are provided on the top of 2 junction of shaft 10 and sliding block, sliding block 2 The groove face of shape limiting slot 8 be the flank of tooth, chalk clamp shelve 3 and sliding block 2 combine that side end face on be fitted with support shaft 7, prop up The support rolling of axis 7 is installed in arc limit slot, and arc limit slot can make that chalk clamp is shelved and pedestal forms one within the scope of 0 ° to 90 ° Determine angle, so as to adjust the spacing of four lines, three lattice, makes that line lattice are more attractive, are more convenient for writing, further increase teaching efficiency.

As shown in Fig. 2, the two sides of sliding block 2 are equipped with boss 11, sliding block 2 is flush-mounted in groove 5 by boss 11, makes sliding block can be Sliding in groove, to facilitate drafting short-term；As shown in figs. 1 and 4, pedestal 1 is cuboid pedestal, rectangular along cuboid pedestal item To side on be bonded with felt cloth 6, side in the width direction, internal hollow out, hollow out position is provided with articles ride room 13, room door 9, bottom are connected at the top of articles ride room 13 equipped with magnet 14, felt cloth can be used as blackboard eraser use, articles ride room The small-sized scattered teaching aid such as chalk, clip, binder clip can be placed, is convenient for carrying, smallclothes teaching aid loss is also prevented from；Drafting finish into When the writing on the blackboard that row demonstration is write, the present apparatus can be adsorbed on to writing on the blackboard blackboard side, facilitate used as needed, prevent from upsetting teaching section It plays, further increases teaching efficiency.

Particularly, if pedestal is cuboid pedestal, along the side and in the width direction of cuboid pedestal length direction Side respectively there are two, then settable felt cloth, articles ride room on opposite sides, to efficiently use space, into One step facilitates writing on the blackboard, carries a variety of small-sized teaching aids.
