Abstract

The utility model discloses an automatic music stand, which comprises an upper stand for placing music. The upper stand is provided with a pair of mutually parallelled upper reel and lower reel and a driving mechanism for driving the upper reel to rotate. The music is rolled on the lower reel, and the front end of the music is dragged by the upper reel. The utility model has the advantages that the music with a traditional single page or cost is changed into a long reel shape, the automatic and continuous page turning of the music can be conveniently realized through the dragging of the reels, and the driving mechanism and a transmission mechanism have simple structures and reliable movements.

Description

Automatic music stand

Technical field

The utility model relates to a kind of music stand, relates in particular to the music stand of energy automatic repagination.

Background technology

Traditional music stand is made up of support and the shelf that is positioned at the support upper end in structure, and the music score of single page or cost is put on shelf, along with the carrying out of playing, needs use the handspring page or leaf, uses inconvenience.So people have invented the music stand of energy automatic page turning on this basis.This class automatic page turning music stand still uses the music score with single page or cost, by the page turning of mechanical pendulum actuation mechanism, has mechanism's complexity, the defective that reliable in action is not high, and in stirring process, understand the sight line that influence the player.

The utility model content

Technical problem to be solved in the utility model provides a kind of music stand that can skip continuously automatically simple in structure.

The technical scheme that its technical matters that solves the utility model adopts is: automatic music stand of the present utility model, comprise the upper bracket that is used to lay music score, it is characterized in that: a pair of upper winding shaft that is parallel to each other, lower winding shaft are installed on the described upper bracket, and drive the driving mechanism that upper winding shaft rotates; Music score is rolled up on lower winding shaft, and its front end is dragged by upper winding shaft.

The beneficial effects of the utility model are, the music score of traditional single page or cost is changed into the long paper shape, by dragging of spool, can realize skipping continuously automatically of music score easily, and driving and gear train are simple in structure, reliable in action.

Description of drawings

This instructions comprises following two width of cloth accompanying drawings:

Fig. 1 is the structural representation of the automatic music stand of the utility model;

Fig. 2 is the vertical view of upper bracket in the automatic music stand of the utility model.

Parts, position and numbering among the figure: lower carriage 10, upper bracket 11, hinge 12, music score 13, support chip 14, support chip 15, upper winding shaft 20, clip slot 21, driven pulley 22, lower winding shaft 30, clip slot 31, driven pulley 32, driving mechanism 40, installing plate 41, motor 42, speed reduction unit 43, active friction wheel 44.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As shown in Figure 1, automatic music stand of the present utility model comprises the upper bracket 11 that is used to lay music score 13.As shown in Figure 1 and Figure 2, a pair of upper winding shaft that is parallel to each other 20, lower winding shaft 30 are installed on the upper bracket 11, and drive the driving mechanism 40 that upper winding shaft 20 rotates.Music score 13 is rolled up on lower winding shaft 30, and its front end is dragged by upper winding shaft 20.Music score can directly be printed on the ribbon base, also can directly traditional sheet music be sticked on this ribbon base in order.

As shown in Figure 2, driving mechanism 40 comprises motor 42, the speed reduction unit 43 that is fixed on the installing plate 41.Can pass through gear, belt pulley, friction wheel transmission etc. between the axle of speed reduction unit 43 output shafts and upper winding shaft 20, but consider, should adopt the friction wheel transmission from reduce the running noises angle as far as possible.As shown in Figure 2, be set with initiatively friction wheel 44 on speed reduction unit 43 output shafts, this active friction wheel 44 cooperates with driven pulley 22 transmissions that are arranged on upper winding shaft 20 axial ends.In the playing procedure, it is up that upper winding shaft 20 rotations drag music score 13, and its travelling speed can change the rotating speed of motor 42 and realization easily by control circuit.

Drag music score 13 backrush for rotating by lower winding shaft 30, be connected by hinge 12 between installing plate 41 and the upper bracket 11, be respectively arranged with the support chip 14 that is used for support mounting plate 41 in hinge 12 both sides on the

support

11,15, lower winding shaft 30 axial ends are provided with driven pulley 32, when driving mechanism 40 along with installing plate 41 around hinge 12 after upset puts in place downwards, driven pulley 32 cooperates with 44 transmissions of active friction wheel, can control the rotating of motor 42 by control circuit, can drive upper winding shaft 20 respectively by a cover driving mechanism like this, lower winding shaft 30 rotates, and music score 13 is unreeled, rolling.

For easily music score 13 two ends being connected with upper winding shaft 20, lower winding shaft 30, as shown in Figure 2, can on upper winding shaft 20, lower winding shaft 30, offer respectively along its axially extended clip slot 21,31.As shown in Figure 1, upper bracket 11 is fixed on lower carriage 10 upper ends by a rotating axle sleeve, makes the inclination of upper bracket 11 adjustable, and lower carriage 10 has pedestal and adjustable for height vertical rod.

It is to be noted, above the described principles more of the present utility model that just explain through diagrams, because the those of ordinary skill to constructed field is easy to carry out on this basis some modifications and change, therefore this instructions be not be the utility model to be confined to shown in and in the described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
