Description

Be suitable for four line lattice renderers for English teaching

Technical field

The utility model relates to English-teaching aid technical field, specifically relates to and is suitable for four line lattice renderers for English teaching.

Background technology

In process of English teaching, its writing on the blackboard has special code requirement, and the position that each letter is write on English stave is different, therefore, in process of English teaching, is widely used four line lattice. In process of English teaching, often need on blackboard, draw four line lattice; Traditional way is that teacher utilizes ruler to draw one by one, is unfavorable for like this controlling the distance between horizontal line, and operating efficiency is also very low simultaneously.

Utility model content

Technical problem to be solved in the utility model be to provide a kind of simple in structure, easy to use, draw efficiency high be suitable for four line lattice renderers for English teaching.

For solving the problems of the technologies described above, the utility model provides following technical scheme: be suitable for four line lattice renderers for English teaching, comprise T-shaped chi plate, drawing apparatus, described chi plate connects to form by transverse slat is vertical with riser; Described drawing apparatus comprises pressing plate, the U-shaped sliding sleeve corresponding with riser, be connected in telescopic mast between pressing plate and sliding sleeve, be sheathed on the Compress Spring in telescopic mast outside, described pressing plate bottom surface is laterally evenly fixed with four chalk sleeves, in each chalk sleeve, be fixed with chalk, side, described riser both sides embeds chute, the described sliding sleeve both sides sliding part corresponding with chute that extend internally respectively, described sliding sleeve was realized and being slidably connected on riser by coordinating of sliding part and chute.

Preferential on such scheme basis, described sliding sleeve is placed between middle two chalk sleeves.

Preferential on such scheme basis, the chute of described riser both sides extends to riser two ends.

Preferential on such scheme basis, on described pressing plate, be provided with hand holding handle.

Preferential on such scheme basis, on described transverse slat, be provided with length graduation mark.

Preferential on such scheme basis, on described riser, be provided with length graduation mark.

The beneficial effect that the utility model compared with prior art has is: the renderer that the utility model provides, under its pressing plate, be connected with four chalks arranged side by side, and be convenient to the disposable four line lattice of drawing out, drafting efficiency is high; Pressing plate is slidably connected to by sliding sleeve on the riser of T-shaped chi plate, can utilize chi plate to position, and improves line drawing specification and precision; , between pressing plate and sliding sleeve, be connected by telescopic mast and Compress Spring meanwhile, can impel chalk to move down with blackboard to contact by pressing the mode of pressing plate, improve chalk utilization rate.

Number in the figure is: 1-chi plate, 2-transverse slat, 3-riser, 4-pressing plate, 5-sliding sleeve, 6-telescopic mast, 7-Compress Spring, 8-chalk sleeve, 9-chalk, 10-chute, 11-sliding part, 12-hand holding handle, 13-length graduation mark.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

In description of the present utility model, it will be appreciated that, term " longitudinally ", " laterally ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of instructions such as " outward " are based on orientation shown in the drawings or position relationship, it is only the utility model for convenience of description, instead of device or the element of instruction or hint indication must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted as restriction of the present utility model.

See figures.1.and.2 known, be suitable for four line lattice renderers for English teaching, comprise T-shaped chi plate 1, drawing apparatus, described chi plate 1 connects to form by transverse slat 2 is vertical with riser 3; Described drawing apparatus comprises pressing plate 4, the U-shaped sliding sleeve 5 corresponding with riser 3, be connected in telescopic mast 6 between pressing plate 4 and sliding sleeve 5, be sheathed on the Compress Spring 7 in telescopic mast 6 outsides, described pressing plate 4 bottom surfaces are laterally evenly fixed with four chalk sleeves 8, in each chalk sleeve 8, be fixed with chalk 9, described riser 3 sides, both sides embed chute 10, the described sliding sleeve 5 both sides sliding part corresponding with chute 10 11 that extend internally respectively, described sliding sleeve 5 was realized and being slidably connected on riser 3 by coordinating of sliding part 11 and chute 10.

Wherein, telescopic mast belongs to common structure, for example, can realize by two joint extension sleeves, repeats no more herein.

Wherein, in the middle of being placed in, described sliding sleeve 5 between two chalk sleeves, improves pressing plate 4 balances.

Wherein, on described pressing plate 4, be provided with hand holding handle 12, be convenient to utilize hand holding handle 12 to operate pressing plate 4 slip operations.

The renderer that the utility model provides, its pressing plate is connected with four chalks 9 arranged side by side for 4 times, is convenient to the disposable four line lattice of drawing out, and drafting efficiency is high; Pressing plate 4 is slidably connected on the riser 3 of T-shaped chi plate 1 by sliding sleeve 5, can utilize chi plate 1 to position, and improves line drawing specification and precision; , between pressing plate 4 and sliding sleeve 5, be connected by telescopic mast 6 and Compress Spring 7 meanwhile, can impel chalk to move down with blackboard to contact by pressing the mode of pressing plate 6, improve chalk utilization rate.

Better, the chute 10 of riser 3 both sides extends to riser two ends. So, just the pressing plate 4 in line drawing device can skid off with riser 3 and separate from riser 3, T-shaped chi plate 1 can be used alone as elsewhere, and as for drawing straight line, right angle etc., applicability is strong; In the time that drawing four line lattice, assemble again by needs, and easy to use.

Better, transverse slat 2 is provided with length graduation mark 13, is also provided with length graduation mark 13 on riser 3. Utilize length graduation mark to be convenient to measure movable plate sliding distance, improve and draw length accuracy; Also can, in the time that T-shaped chi plate is used as elsewhere, measure length etc.

These are only preferred embodiment of the present utility model, not in order to limit the utility model, all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
