Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment, belongs to the scope of protection of the invention.
- 3 are please referred to Fig.1, the present invention provides a kind of technical solution：Piece device, including handle 1, folder are held in dental piece photography
First 7 and housing 5, the side of the handle 1 is fixedly connected with fixed plate 3, in the fixed plate 3 fixation be plugged with light source-guide circle
4, one end of the handle 1, which is fixed, is plugged with connecting rod 9, and the inside of the housing 5 is provided with first gear 8, second gear 10
With the 3rd gear 11, and 8 and the 3rd gear 11 of first gear engages 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, which is fixed, to be connected
One end of central shaft 12 on the 3rd gear 11 is connected to, it is 2 times of 8 diameter of a diameter of first gear of the 3rd gear 11, described
Light source-guide circle 4 is perpendicular to handle 1, and 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 guiding circle 4, offers (the bar hole 2 of bar hole 2 in the handle 1, fixed plate 3 and connecting rod 9 respectively
Effect be to mitigate weight).
Operation principle：When application angular bisector is thrown and shines into the shooting of row tooth piece, often increase when tooth piece and by the angle of bat tooth
When adding 1 degree, the direction of X-ray just only need to rotate 0.5 degree along the rotating direction of tooth piece, 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 handle 1 of source parallel is also automatically rotated to relevant position, and when clapping tooth piece, X source is shot along the direction of handle, and light source is agreed
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, adjusted using the diameter of handle 1 the 3rd gear 11 connected and the first gear 8 for fixing tooth piece
Connecting handle 1 (be the X source along handle 1) and tooth piece angle are saved, makes X source all the time perpendicular to by bat tooth and dental film holder
The perpendicular bisector at angle, in this way, be exactly standard angular bisector throw shine method, when tooth piece is parallel with by bat tooth, X source just with
Tooth piece and tooth are parallel, so also just shoot tooth piece for parallel projection method, can similarly take the tooth piece of high quality.
Work as X source degree of rotation due to being aware of, when tooth piece must rotate twice in the same direction, can be only achieved X source
Perpendicular to tooth piece and the perpendicular bisector by bat tooth angle, here, we make the diameter of the 3rd gear 11 of connection handle 1 be
Twice of 8 diameter of first gear of the fixed tooth piece of connection, (diameter of middle second gear 10 does not require, because 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 big rotating angle of the rotating gear diameter in direction is small, and the small rotation angle of diameter is big, is direct proportionality；Wherein the 3rd
When the diameter of gear 11 is twice of 8 diameter of first gear, 11 rotating angle of the 3rd gear is exactly 8 rotation angle of first gear
Half.Herein, X source is parallel with handle 1, so just making X source perpendicular to tooth piece with being put down by the angle of bat tooth
Separated time.
When clapping dental piece, it is desirable to 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
Device is shone in throwing, throws angular bisector and combines 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 bat tooth piece more easy to learn, film making people need not estimation tooth piece and tooth angle the problems such as, during film making also without
Palpus patient fixes tooth piece with hand, and when patient bites housing, tooth piece can be adjusted to the position of patient comfort by rotation handle 1,
X source is loaded can on light source-guide circle.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
