Description

A kind of English study shorthand device

Technical field

The present invention relates to a kind of English study shorthand devices.

Background technology

It is well known that the study of English has been rooted in the hearts of the people, in English study, completing to remember on the basis of understanding is The most important thing.How quickly to realize that memory is also the part of numerous students most headache in learning English.It is how firm Master English word, teachers thought many methods, but most methods effect is all undesirable.On the other hand, English study Memory Process is uninteresting in most of Eyes of Students, and attention is difficult high concentration, how to improve student's following period of time collection Middle attention and teachers need the problem of thinking.

Invention content

The object of the present invention is to provide a kind of English study shorthand devices, and student is helped to improve attention, realize the short time Rapid memory.

To achieve the goals above, the present invention adopts the following technical scheme that：

A kind of English study shorthand device, upper annulus open circles circumference are downwardly protrude to form cylinder, lower annulus open circles Cylinder under circumference formation protruding upward, roller are connect by bearing with the upper cylinder and the lower cylinder, and center pillar passes through described Roller, and both ends are separately fixed at by fixed link on the side wall of the upper cylinder and the lower cylinder, and the cylinder wall is set Longitudinal oblong openings to be set, clockwork spring is set in the roller, the center-side of the clockwork spring is fixed on the center pillar, Outer end connection connection sheet one end of the clockwork spring, the connection sheet other end pass through the opening to connect clip, memory stick One end is clamped by the clip, and the other end is connected on handle, is arranged timer in the upper cylinder, the upper annulus and described Connecting rod is arranged in lower annular edge, link is arranged among the connecting rod, the upper annulus and the lower annular edge are also set up Notch, the notch is interior to be arranged timer switch.

It is preferred that：The space for being formed to the roller sunken inside and accommodating the clip that is open.

It is preferred that：The upper annulus is identical with the lower annulus size.

It is preferred that：The connection sheet can be bent, and length be more than the upper annulus great circle and open circles radius it Difference.

It is preferred that：The width of the clockwork spring is less than the width of the connection sheet, and the width of the connection sheet is less than described The width of memory stick.

It is preferred that：The notch is arranged in the connecting rod offside.

It is preferred that：The timer switch is arranged in the notch of the upper annulus.

Beneficial effects of the present invention：

1. annulus open circles circumference is downwardly protrude to form cylinder on, justifies under the formation protruding upward of lower annulus open circles circumference Cylinder, roller are connect by bearing with upper cylinder and lower cylinder, and roller is allow to rotate, and roller rotation makes memory stick be rolled onto roller On, handle, which pulls outward, makes memory stick from roller under.The connection type of bearing makes roller be supported, while roller being made to be easy Rotation.

2. center pillar passes through roller, and both ends are separately fixed at by fixed link on the side wall of upper cylinder and lower cylinder, thus Center pillar is fixed with cylinder.The setting of upper cylinder and lower cylinder provides the installation space of fixed link, and device is made more to step up on the whole It gathers, saves space, optimization component layout.

3. cylinder wall setting opening, is open as longitudinal rectangle, opening is recessed the space for accommodating clip, makes clip It is stuck in opening, clip, which is stuck in opening, to be entered in roller, and is unlikely to that clip is made to form protrusion on roller, influence Silver lap is remembered on roller.

4. clockwork spring is arranged in roller, the center-side of clockwork spring is fixed on center pillar, the outer end connection of clockwork spring Connection sheet one end, the connection sheet other end pass through opening connection clip, memory stick one end to be clamped by clip, and the other end is connected to handle On.Deformation restoring force is provided after clockwork spring deformation, deformation restoring force makes first in connection sheet income to roller, and clip snaps into out At mouthful, deformation restoring force does not discharge complete at this time, however clockwork spring center-side is fixed on center pillar, and deformation restoring force can only By connecting one end release of clip, clip has snapped into opening and interior cannot receive at this time, is rolled under the action of deformation restoring force Cylinder rotation makes memory stick be rolled onto on roller.

5. there is connection sheet between clockwork spring and memory stick, connection sheet can pass in and out roller, and clockwork spring will not be drawn out roller, Memory stick will not be pulled into roller.The setting of connection sheet makes whole device organically combine, the transmission of strength and roller It rolls happier.

6. the width of clockwork spring, connection sheet and memory stick can be different, it is clockwork spring successively that width is ascending, is connected Contact pin, memory stick.Material can be effectively saved, matching performance is more reasonable between making component.The width of memory stick is slightly less than Roller height enables the volume that memory stick is unfolded on roller.

7. annulus is identical with lower annulus size on, and connection sheet is easily bent, and length is more than the great circle and sky of upper annulus The difference of the radius of heart circle, such clip can be moved to outside annulus and lower annulus, keep the replacement of memory stick more convenient.

8. handle is designed for facilitating pull-out memory stick.The length of handle be more than between upper annulus and lower annulus away from From clockwork spring deformation restoring force is unlikely to handle to pull between upper annulus and lower annulus, causes to be not easy to pull out.

9. memory stick can be replaced, the content with the memory of the needs such as English word, english article in memory stick, memory stick After pull-out, clockwork spring deformation restoring force makes attention of student concentrate, and contributes to student's rapid memory, in addition, the present apparatus may be used also To increase the interest of English study, the interest that student challenges English memory is improved.

10. timer is set in cylinder, timing is used for.Timing after pull-out memory stick, is remembered, after withdrawing memory stick Stopping in time, the time of inspection and memory effect give student memory pressure, attention of student are enable to reach high concentration, Contribute to student's rapid memory, the interest of English study can also be increased, improves the interest that student challenges English memory.

Annulus and lower annular edge are arranged connecting rod on 11., connecting rod perpendicular to upper annulus and lower annulus, to upper annulus and Lower annulus plays additional fixed function.Link is set among connecting rod, device can be hung up, realizes one-handed performance, is used It is more convenient.

Notch is arranged in annulus and lower annular edge on 12., and gap position is opposite with connecting rod, and notch provides handle and places sky Between, so that device is designed on the whole more rationally.

13. timer switch is arranged in notch, handle closes timer switch when sticking into notch, handle is opened when taking out notch Timer switch is opened, the timing of the corresponding timer of open and close of timer switch starts and stops.Clockwork spring deformation is extensive Multiple power makes handle tightly be stuck in notch, and handle presses timer switch at this time.

14. helping the electronic equipment of English memory very much, also there are many softwares to contribute to English memory, but these Instrumental function is excessive, is easy that attention of student is made to disperse.The present apparatus carries the English information for needing to remember by memory stick, uses Simply, function has specific aim.
