Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1-3, the present invention provides a kind of technical solution: piece device, including handle 1, folder are held in dental piece photography
First 7 and shell 5, the side of the handle 1 is fixedly connected with fixed plate 3, and fixation is plugged with light source-guide circle in the fixed plate 3
4, one end fixation of the handle 1 is plugged with connecting rod 9, and the inside of the shell 5 is equipped with first gear 8, second gear 10
With third gear 11, and first gear 8 and third gear 11 engage connection with second gear 10 respectively, and described 5 one end of shell is opened
Equipped with opening 6, the collet 7 is through opening 6 and is fixedly connected in first gear 8, and one end of the connecting rod 9 is fixed to be connected
It is connected to one end of central axis 12 on third gear 11, the diameter of the third gear 11 is 2 times of 8 diameter of first gear, described
For light source-guide circle 4 perpendicular to handle 1, the connecting rod 9 is L-shaped, and the fixed plate 3 is structure as a whole with handle 1, the light source
X source is installed on guidance circle 4, offers (the strip-shaped hole 2 of strip-shaped hole 2 in the handle 1, fixed plate 3 and connecting rod 9 respectively
Effect be to mitigate weight).
Working principle: when the shooting of row tooth piece is shone into application angular bisector throwing, when tooth piece and by the every increasing of the angle of bat tooth
When adding 1 degree, the direction of X-ray just only need to rotate 0.5 degree along the direction that tooth piece rotates, in this way, X source is still perpendicular to tooth piece
With by the folder bisector of angle of bat tooth, so, no matter tooth piece is in the oral cavity and by which type of angle of bat dentification and X
The parallel handle 1 of light source is also automatically rotated to corresponding position, and when clapping tooth piece, X source is shot along the direction of handle, and light source is agreed
It surely can be perpendicular to tooth piece in the angular bisector of tooth, in this way, good tooth piece will easily be shot very much.
When in use, it is adjusted using the diameter of the first gear 8 of the third gear 11 of the connection of handle 1 and fixed tooth piece
Connecting handle 1 (be the X source along handle 1) and tooth piece angle are saved, makes X source always perpendicular to by bat tooth and dental film holder
The perpendicular bisector at angle, in this way, be exactly that the angular bisector of standard is thrown according to method, when tooth piece is parallel with by bat tooth, X source just with
Tooth piece and tooth are parallel, also just shoot tooth piece in this way for parallel projection method, can similarly take the tooth piece of high quality.
Due to being aware of when X source degree of rotation can be only achieved X source when tooth piece must rotate two degrees in the same direction
Perpendicular to tooth piece and by the perpendicular bisector of bat tooth angle, here, we make the diameter of third gear 11 for connecting handle 1 be
It is connected and fixed twice of 8 diameter of first gear of tooth piece, (diameter of intermediate second gear 10 does not require, because of linear velocity
First, second, and third gear is the same), the linear velocity of three groups of gears is the same, so when three groups of gears rotate together, together
The angle of the big rotation of the gear diameter that direction rotates is small, and it is direct proportionality that the small rotation angle of diameter is big；Wherein third
When the diameter of gear 11 is twice of 8 diameter of first gear, the angle that third gear 11 rotates is exactly that first gear 8 rotates angle
Half.Herein, X source is parallel with handle 1, so putting down X source with by the angle of bat tooth perpendicular to tooth piece
Separated time.
When clapping dental piece, it is desirable that throw photograph with angular bisector or parallel projection method two ways is made film, present market only has
Parallel projection holding clip, no angular bisector hold piece device, and the blank in the domestic and international field has been filled up in our this invention；This
It throws and shines device, throw angular bisector and combine according to parallel projection, piece device can also be held with this and carries out parallel projection；Parallel projection
Actually operation is difficult, is the substitute products of parallel projection device because it is only suitable for the big people's shooting in oral cavity；Piece is held using this
Device claps tooth piece, makes to clap that tooth piece is more easy to learn, film making people need not estimation tooth piece and tooth angle the problems such as, when film making also without
Palpus patient fixes tooth piece with hand, and when patient bites shell, tooth piece can be adjusted to the position of patient comfort by rotating handle 1,
X source is packed into can on light source-guide circle.
