Description
Technical field:
The utility model belongs to music teaching apparatus field, and in particular to a kind of apparatus for demonstrating for Chinese zither teaching.
Background technique:
In Chinese zither teaching, the basis that hand-type is fingering teaching is played, and in the classroom Piano Teaching of major arts institutions
In, student can only be centered around piano and look on the teaching demonstration for seeing that teacher play hand-type, due to viewing angle difference and
The demonstration that hand-type can not be seen clearly affects the grasp of student's hand-type correct for Zither playing.Both the teaching of inconvenient teacher was drilled
Show, and affects learning quality.So design it is a kind of for Chinese zither teaching apparatus for demonstrating be very necessary.
Utility model content:
The purpose of the utility model is to provide a kind of apparatus for demonstrating for Chinese zither teaching.By multimedia presentation, teacher is drilled
The hand-type and fingering of Chinese zither are played, student is not required around teacher and learns fingering and playing technique, can clearly see convenient for student
The demonstration of teacher's performance is observed, and the apparatus for demonstrating is not only easy to remove but also firm, improves the quality of instruction of Chinese zither, structure letter
Single, design is rationally, low in cost, economic and practical.
The technical solution adopted in the utility model are as follows: a kind of apparatus for demonstrating for Chinese zither teaching, including camera shooting projector,
Support rod, disc base and four arc turning rolls；The camera shooting projector is located on the bracket of supporting bar top, camera shooting projection
The camera of instrument is installed on the top of coiled pipe, and coiled pipe is fixed on the axle sleeve hinged with support rod, the support of axle sleeve bottom
Bar is equipped with the shaft shoulder；The camera is connect by conducting wire with camera shooting projector；The supporting bar top is installed on disc base
On；The arc turning rolls is welded on detent casing seat, is set on detent casing seat there are two symmetrical detent track, is blocked
Position track includes lower detent slot and upper detent slot, and two position blocking pin axle positions positioned at support rod lower part are in detent track；It is described
Arc turning rolls bottom end is equipped with idler wheel.
It further, further include main frame and display screen, the main frame is located at support rod lower part equipped with machine
On case pallet；The display screen is hung on wall；The display screen is connect by conducting wire with main frame, main frame
It is connect by conducting wire with camera.
Further, the difference in height of the bottom of the upper detent slot and lower detent trench bottom is not less than 3 centimetres.
The utility model has the beneficial effects that structure is simple, design is rationally, easy to operate, low in cost, economic and practical, easily
In popularization on a large scale and use.The hand-type and fingering of Chinese zither are played by multimedia presentation teacher, student is not required around always
Teacher learns fingering and playing technique, the demonstration of teacher's performance can be clearly observed convenient for student, and the apparatus for demonstrating was both
It is easy to remove and firm, the quality of instruction of Chinese zither is improved, classroom discipline is also maintained.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of detent casing seat in the utility model；
Fig. 3 is the expanded schematic diagram of detent track in the utility model；
Fig. 4 is the structural schematic diagram of embodiment two.
Specific embodiment:
Embodiment one
Referring to figs. 1 to Fig. 3, a kind of apparatus for demonstrating for Chinese zither teaching, including camera shooting projector 1, support rod 11, disk
Pedestal 9 and four arc turning rolls 7；The camera shooting projector 1 is located on the bracket 2 on 11 top of support rod, camera shooting projector 1
Camera 3 is installed on the top of coiled pipe 4, and coiled pipe 4 is fixed on the axle sleeve 12 hinged with support rod 11,12 bottom of axle sleeve
Support rod 11 is equipped with the shaft shoulder 5；The camera 3 is connect by conducting wire with camera shooting projector 1；11 top of the support rod installation
In on disc base 9；The arc turning rolls 7 is welded on detent casing seat 6, is set on detent casing seat 6 and is divided there are two symmetrical
The detent track 14 of cloth, detent track 14 include lower detent slot 15 and upper detent slot 13, two cards positioned at 11 lower part of support rod
Position pin shaft 10 is located in detent track 14；7 bottom end of arc turning rolls is equipped with idler wheel 8；The bottom of the upper detent slot 13
It is not less than 3 centimetres with the difference in height of lower 15 bottom of detent slot.
Position and the angle of camera 3 can be arbitrarily adjusted by the axle sleeve 12 and coiled pipe 4 of rotation, so that students' energy
It is enough clearly seen that zither playing hand-type and the fingering projected on curtain or wall by imaging projector 1, improves the quality of teaching.
When carrying out demonstration performance hand-type and fingering, two detent pin shafts 10 are located in the lower detent slot 15 of detent track 14, this
When disc base 9 and ground face contact and be responsible for load-bearing, ensure that the stability of whole device.Mobile dress is needed after demonstration
It when setting, above mentions support rod 11 and detent pin shaft 10 is stuck in detent slot 13, at this time idler wheel 8 and ground face contact, and disk bottom
