Abstract
The utility model discloses an English four-line grid scriber which comprises an outer frame, an adjusting knob, a threaded column, pressure springs, main connecting rods, hinge shafts, auxiliary connecting rods, large gaskets, connecting seats, chalk sleeves, chalks, rubber sleeves, crossbeams, nuts, screws and a connecting plate. A rectangular opening is formed in the middle of the lower frame of the outer frame. Slide grooves are formed in the inner middles on two sides of the outer frame. Two ends of the connecting plate extends into the slide grooves and can slide up and down. The threaded column is fixedly connected to the middle of the connecting plate. The upper end of the threaded column penetrates the outer frame. The adjusting knob is screwed into the threaded column. The two pressure springs are symmetrically disposed between the connecting plate and outer frame and on two sides of the threaded column. The two crossbeams are disposed between the connecting plate and the lower frame of the outer frame. The connecting seats are disposed on the chalk sleeves and hinged with the auxiliary connecting rods. Every two adjacent auxiliary connecting rods are hinged to be hinged with one main connecting rod. The English four-line grid scriber has the advantages that linkage of the four chalk sleeves can be achieved by manually rotating the adjusting knob, and the intervals of the four chalks can be changed.
Description
Technical field
The utility model relates to a kind of English stave scriber, belongs to English teaching aid technical field.
Background technology
At present, in English teaching, often on blackboard, draw four line lattice, on blackboard, draw four line lattice and normally use ruler and chalk, sometimes also will make of set square auxiliary, think being neatly carefully and neatly not easy very much of picture, lose time again, impact teaching, although worked out many scribers now, mostly all belong to the scriber of constant spacing, practical function is not desirable especially.
Summary of the invention
In order to address the above problem, the utility model provides a kind of English stave scriber, and this scriber can regulate the spacing of four line lattice, convenient, fast, the parallel neat appearance of four line lattice drawing.
The utility model solves the technical scheme that its technical problem adopts: a kind of English stave scriber is comprised of outside framework, circle cover, adjusting knob, threaded column, compression spring, master link, hinge, secondary connecting rod, large washer, Connection Block, bush of chalk, chalk, rubber sleeve, disk, horizontal Beam, nut, screw rod and connecting plate.Outside framework is a cuboid, the elongated oblong openings that is provided with in the middle of the lower frame of its cuboid, and center, outside framework top is provided with circular hole, on circular hole, be fixed with circle cover, outside framework both sides bosom is provided with chute, and connecting plate is an elongated plates, and connecting plate is parallel with upper and lower side frame, two ends are stretched in chute, can slide up and down, the centre of connecting plate is fixedly connected with threaded column, and threaded column upper end is set to outside framework outside through circle, adjusting knob is positioned at circle and puts, and screws in threaded column; In threaded column both sides, between connecting plate and outside framework, be arranged with two compression springs.On the same plane between connecting plate and the lower frame of outer rim, be provided with two crossbeams, the width of the oblong openings in the middle of the spacing between two crossbeams, the diameter of bush of chalk and lower frame is identical.Bush of chalk is provided with Connection Block, Connection Block and secondary connecting rod are hinged, two hinged hinged master links of adjacent secondary connecting rod, master link has three, the other end of master link is fixed on connecting plate, the center that is located at connecting plate, one of centre of master link, other two symmetrical can horizontally slipping on connecting plate.The upper end of bush of chalk is fixedly connected with screw rod, with nut, bush of chalk is fixed on to the top of two horizontal Beam by large washer.The disk of the protrusion on bush of chalk is stuck under oblong openings, and bush of chalk can horizontally slip.
The beneficial effects of the utility model are: this scriber is reasonable in design, simple in structure, easy to operate, be convenient for carrying, by hand rotation adjusting knob, can make four bush of chalks link, and then change the spacing of four chalks, by reality, use, effect is very good, is the line-drawing device for English teaching that a kind of serviceability is good.
