Abstract

The utility model provides a pedal automatic score turning device which is attached on a music stand and consisting essentially of a pedal, an II-shaped framework, a mini cylinder, an adjusting valve, a gear rack, a gear, a rotating rod and a sorption brush. While a pedal is trampled by one foot, the mini cylinder immediately becomes vacuum and transmits the suction to the sorption brush by a hose, at the same time, the gear rack meshes with the gear and drives the rotating rod to rotate for 120 degrees, whereby finishing the turning of one page of the score by the sorption brush. Compared with the existing score turning machines, the utility model has the advantages of simple structure, easy control, reliable operation and convenient maintenance and can avoid turning of more than two pieces of the score in a single time.

Description

The foot-operated spectral apparatus that turns over automatically

Technical field

The utility model relates to sheet music stand, is specifically related to a kind of foot-operated spectral apparatus that turns over automatically.

Technical background

Philharmonic society commander or instrument playing personnel, when hand-held spillikin was waved or handed musical instrument and plays wind and string instruments, the whole body full god be used to annotate, and both hands are busy not to stop, and music score is in time stirred in inconvenience, if be deadlocked, then has a strong impact on commander's atmosphere and playing effect.Therefore, need a kind of needn't be manual, only need the foot-operated spectral apparatus that turns over, to satisfy the smooth smoothly commander and the need of performance.

Existing various music leaf turner adopts ten or twenties such as stay cord, pull bar, slipping ring, shifting block, plectrum, driving lever, a dial parts to form, and its structure is complicated, and it is reliable that operation is owed, and maintenance is trouble; And often once stir music score more than two pages, be difficult to be promoted the use.

The utility model content

At the prior art above shortcomings, the purpose of this utility model be to provide a kind of simple in structure, be easy to control, operate the foot-operated spectral apparatus that turns over automatically reliable, easy to maintenance.

The purpose of this utility model is achieved in that a kind ofly foot-operated turns over spectral apparatus automatically, and it is characterized in that: II type framework on the music easel column, forms upper lever and following lever with upper and lower two pin cross-under; Following lever front end is connected with pedal, and links to each other with miniature cylinder piston rod, the parallel bending of upper lever front end, and become one with tooth bar, and the tooth bar meshing gear, gear shaft tightens rotating bars, and the rotating bars upper end is connected with the absorption brush.

Described riding turned over spectral apparatus automatically, it is characterized in that: miniature cylinder exit, and an elongated flexible tube is housed links to each other with the absorption brush, a control valve is installed on the flexible pipe.

The utility model remedies the deficiency of existing various music leaf turners on the basis of prior art, innovated and improve.Have simple in structure, be easy to control, the reliable and easy to maintenance advantage of operation.

The specific embodiment

As depicted in figs. 1 and 2, the foot-operated spectral apparatus that turns over automatically of the utility model, be by pedal 1, part parts such as ∏ type framework 3, minitype cylinder 6, flexible pipe 12, control valve 7, tooth bar 8, gear 9, rotating bars 10, absorption brush 11 are formed, two pin cross-under are on the column of music easel about ∏ type framework 3 usefulness, upper lever 4 and following lever 2 that formation can prize synchronously, following lever 2 is affixed with pedal 1, and links to each other with the piston rod 5 of miniature cylinder 6.Miniature cylinder 6 is fixed on the column of music easel; The parallel bending of upper lever 4 front ends, the vertical affixed toothed rack 8 in top, tooth bar 8 and gear 9 engagements, the space that upper lever 4 bent part are vacateed just gear 9 in the face of the centre position of music easel.Gear 9 is fixed on the music easel separately, and tighten a rotating bars 10 at gear shaft, rotating bars 10 upper ends are connected with absorption brush 11 lower ends, absorption brush 11 tilts to be shelved on the music easel left side, and the upper end of absorption brush 11 is communicated with an elongated flexible tube 12, flexible pipe 12 other ends then join with miniature cylinder 6 outlets, and a control valve 7 is housed.

When monopodia steps down on the pedal gently, under external force, the following lever of II type framework, the piston rod that spurs miniature cylinder moves down, and produces instantaneous vacuum, by flexible pipe suction is delivered in absorption and brushes.Meanwhile, the upper lever of ∏ type framework and tooth bar move down with relating to, and tooth bar meshing gear driven rotary bar rotation 120 degree stir one page music score thereby finish the absorption brush.After monopodia left pedal, the absorption brush returned original position.When needing, step down on the pedal with monopodia again, then can stir second page, the 3rd page, by that analogy, go round and begin again.Have light characteristics small and exquisite, easy to use.

Parts of the present utility model can adopt light metal material or engineering plastics processing and fabricating.Flexible pipe is selected flexiplast or rubber for use; Control valve on the flexible pipe as the miniature stopcock of the patient infusion of hospital, can be regulated the vacuum of miniature cylinder according to music score paper thickness and newness degree, and snugly satisfies the page turning demand, and absorption affinity is excessive stirs two pages or multipage music score to avoid.

Claims

1, a kind of riding turned over spectral apparatus automatically, it is characterized in that: ∏ type framework on the music easel column, forms upper lever and following lever with upper and lower two pin cross-under; Following lever front end and pedal join, and link to each other with miniature cylinder piston rod, the parallel bending of upper lever front end, and become one with tooth bar, and the tooth bar meshing gear, gear shaft tightens rotating bars, and the rotating bars upper end is connected with the absorption brush.

2, turn over spectral apparatus automatically according to claims 1 described riding, it is characterized in that: miniature cylinder exit, an elongated flexible tube is housed links to each other with the absorption brush, a control valve is installed on the flexible pipe.
