Abstract

The utility model relates to an automatic music book turning instrument which comprises a bookshelf panel and a control button which is connected with a lead wire of the bookshelf panel; the bottom side of the bookshelf panel is provide with a page clamping device; and a mechanical arm capable of swinging left and right is arranged in the middle of the bookshelf panel below the book clamping device. The mechanical arm comprises a turning motor, a page turning rod, a clamping motor, an expansion link with the head inclining upwards, an auxiliary contact shaft with the head bending upwards, a reel motor, an auxiliary contact and a page turning reel. A music book is put on the bookshelf panel; when the pages need to be turned, the control button is pedaled by foot or pressed down by hand; and the mechanical arm moves to turn the pages. The automatic music book turning instrument can provide convenience for the player when an instrument is played; and the structure is simple, the pages are turned stably, the turning times is not restricted, so the automatic music book turning instrument is applicable to music books with any size, and has wide practicality.

Description

A kind of spectrometer that turns over automatically

Technical field

The utility model relates to a kind of spectrometer that turns over automatically, is particularly useful for stirring of music player music score, also is applicable to the crowd that some inconveniences are manually browsed books.

Background technology

In musical performance, always there is a problem of turning over spectrum---the player often can't go to turn over spectrum by the both hands of oneself in playing procedure.In various concerts, can only adopt some people to go to turn over the mode of composing another part people performance or adopting happy child to turn over spectrum music is kept perfectly with continuous now; From concert is arranged, people are just studying always and are turning over spectral technology automatically, though multiple design occurred, but all there is limitation, the special music score form of the employing that has, the qualification page turning number of times that has, the qualification music score size that has, page turning instability that has or the like, what also do not occur a kind of maturation on the market turns over spectrometer automatically.

Summary of the invention

The purpose of this utility model is the weak point that overcomes in the prior art, provides a kind of simple in structure, easy to use, the effective spectrometer that turns over automatically.

For achieving the above object, of the present utility modelly turn over spectrometer automatically it comprises the bookshelf panel, with the control button that bookshelf panel lead is connected, the base of bookshelf panel is provided with the page binding clasp, and the below of page binding clasp is positioned at place, bookshelf panel centre position and is provided with a mechanical arm that can swing.

Described page binding clasp is made up of with the page pressing rod that is connected with two page clamping motors respectively two symmetrically arranged left and right sides page clamping motors; Described mechanical arm comprises the upset motor, be connected with the page turning bar on the upset motor, the page turning bar is connected with the acclivitous expansion link of head, the top of expansion link is provided with a reel motor, the reel motor is provided with the page turning reel, be provided with a clamping motor in the expansion link, be connected with the auxiliary contact axle that head is bent upwards on the clamping motor, the auxiliary contact axle is provided with the auxiliary contact that is positioned on the page turning reel; Described page turning bar is provided with and makes the sliding tray that slides before and after the expansion link.

The beneficial effects of the utility model:, also can be some inconveniences and manually browse the crowd of books and provide convenience for the player provides convenience in playing procedure.It is simple in structure, and page turning is stable, and is unqualified to the page turning number of times, and what be applicable to the virtually any size music score turns over spectrometer automatically, has practicality widely.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

Among the figure: left page clamping motor-1, page turning motor-2, page turning bar-3, right page clamping motor-4, control button-5, clamping motor-6, page pressing rod-7, expansion link-8, auxiliary contact axle-9, reel motor-10, auxiliary contact-11, page turning reel-12, music score-13, bookshelf panel-14.

The specific embodiment

The utility model will be further described below in conjunction with the embodiment in the accompanying drawing:

Automatically the spectrometer that turns over of the present utility model, it is mainly by bookshelf panel 14, page binding clasp and the mechanical arm that can swing are formed, bookshelf panel 14 is connected with control button 5 by lead, the page binding clasp is located on the base of bookshelf panel 14, and it is made up of two symmetrically arranged left page clamping motors 1, right page clamping motor 4 and the page pressing rod 7 that is connected with left and right sides page clamping motor 1,4 respectively.The below of page binding clasp is positioned at place, bookshelf panel 14 centre positions and is provided with a mechanical arm that can swing.Mechanical arm is by upset motor 2, page turning bar 3, and clamping motor 6, the acclivitous expansion link 8 of head, the auxiliary contact axle 9 that head is bent upwards, reel motor 10, auxiliary contact 11 and page turning reel 12 constitutes.At the bottom of being fixed on bookshelf panel 14 middle parts, upset motor 2 connects, upset motor 2 connects page turning bar 3, page turning bar 3 connects the acclivitous expansion link 8 of head, the top of expansion link 8 is provided with reel motor 10, page turning reel 12 is located on the reel motor 10, clamping motor 6 is located in the expansion link 8, the auxiliary contact axle 9 that clamping motor 6 upper binding head portions are bent upwards, the auxiliary contact 11 that is positioned on the page turning reel 12 is set on the auxiliary contact axle 9, page turning bar 3 is provided with the chute that is slided in expansion link 8 front and back, expansion link 8 can carry out stretching motion in the chute of page turning bar 3, to adapt to the size of different books.

The course of work: after being placed into music score 13 on the bookshelf panel 14, when needing page turning, foot-operated or press control button 5 with hand, page turning reel 12 just is close to the book angle with certain pressure, reel motor 10 drives page turning reel 12 and turns clockwise, and by frictional force page is rolled up to page turning cylinder 12 tops.That auxiliary contact 11 is rotated to is mutually close with page turning reel 12 in clamping motor 6 rotation then, and both clamp paper with certain pressure.Page turning this moment reel 12 is rotated counterclockwise, and relies on frictional force difference, and unnecessary paper is rolled up to the below of page turning reel 12, guarantees only to leave one page paper between page turning reel 12 and the auxiliary contact 11.When page turning, the left page clamping motor 1 of page binding clasp and 4 actions of right page clamping motor, drive page pressing rod 7 rotations and outwards open an angle, this moment, the page turning motor 2 driving page turning bars 3 of mechanical arm carried out page turning, when page during instead to another side, left and right sides page clamping motor 1,4 drives page pressing rods 7 device returns, clamps page again, auxiliary contact 11 unclamps page, finishes the page turning action.Page turning motor 2 drives page turning bar 3 and resets, and enters next page turning action.
