Detailed Description

Example (b): a dental chair fixing mechanism with a shoulder body head-imitating model comprises a dental chair 1 and a head model, wherein a head model 2 of the head model is positioned on a headrest of the dental chair 1, a shoulder body 3 of the head model is of an internal hollow structure, the bottom of the shoulder body 3 is open, and a semicircular bottom plate 11 can be used for sealing. The semicircular bottom plate 11 is fixed with the bottom of the shoulder body 3 through screws. The semicircular bottom plate 11 is fixed with a vertical column 10. The upright 10 and the semicircular bottom plate 11 have been previously connected as one assembly. A head type connecting shaft 19 capable of connecting the head type 2 is fixed on the upright post 10. Fixing holes are machined in the upright post 10. A back plate 9 capable of fixing three self-locking crimpers is designed, and can be fixed on the back plate 9 through a hole on a self-locking crimper box body 4 by screws, and meanwhile, the back plate 9 can be fixed on a stand column 10 in the shoulder body 3 from the back. Mounting positions of 3 self-locking crimpers on the back plate 9: in the present embodiment, two of the positions are provided on the left and right of the upper edge of the back plate 9, and the other is provided on one side of the back plate 9. The other side of the back plate 9 is designed with an open slot structure 13 for fixing 1 female buckle binding band 12, one end of the open slot structure 13 is open, and the open end can be closed by using a long screw as a sealing baffle plate 14. Both ends of the female buckle binding band 12 are pre-sewed to form closed loop, the binding band loop far away from the female buckle 5 can be inserted into the cantilever structure of the open groove on the side surface of the back plate 9, and then a long screw is used as a sealing blocking piece 14 to close the notch, so that one end of the female buckle binding band 12 is fixed on the back plate 9. With this design, the female buckle strap 12 is also easily replaced if worn over long periods of use. Two groups of hollow structures 15 which can pass through the female buckle binding band 12 are processed on the bottom plate 11 of the shoulder body 3; the binding belt lantern ring penetrating through the hollow structure 15 is fixed by penetrating through a bolt 18, and two ends of the bolt 18 are fixed on a left stop block 16 and a right stop block 17; holes are formed in two ends of the hollow structure 15 of the bottom plate 11, and screws are used for fixing the left stop block 16 and the right stop block 17 on the bottom plate 11 through the holes. According to the pre-designed installation position of the self-locking crimper on the back plate 9 and the fixing position of the female buckle 5, 4 bandage channels are correspondingly opened on the plastic human body part, so that the inserting piece bandage 6 of the self-locking crimper and the bandage of the female buckle 5 can pass through. The whole fixing mechanism is installed on the head die shoulder body 3 in the following sequence:

a) the back plate 9 is screwed to the post 10.

b) The three self-locking crimper boxes 4 are fixed to the back plate 9 by screws.

c) The upright post 10 and the bottom plate 11 are fixed into a component, and free end binding lantern rings of two sets of female buttons 5 penetrate through the hollow structure 15 of the bottom plate 11 and are fixed on the bottom plate 11.

d) Most of the combination bodies are moved into the cavity of the shoulder body 3 of the head die, and the inserting pieces 7 on the three self-locking crimpers respectively penetrate out from the inside to the outside through the first bandage channels of the plastic shoulder body 3.

e) The strap of the third female buckle 5 is threaded through the remaining second strap passage of the head die shoulder body 3 and secured to the back plate 9.

f) The whole assembly is pushed in completely, and the base plate 11 is fixed to the head die shoulder body 3 by screws.

g) The head form 2 of the head die is fixed to the shoulder body 3 by the head form connecting shaft 19, so that the entire interior installation is completed.

The following is the step of fixing the head model to the dental chair 1:

the method comprises the following steps: the clinical dental chair 1 is operated to ensure that the backrest of the dental chair 1 forms an included angle of about 30 degrees with the ground, and the upper head model shoulder body 3 is placed at the included angle so as not to slide downwards;

step two: putting the head model on the backrest of the dental chair 1, properly adjusting the headrest, adjusting the head model 2 and moving the whole head model position to ensure that the back brain of the head model 2 is just completely attached to the center of the headrest;

step three: the bandage with the inserting sheet 7 is pulled out from any side of the shoulder body 3 to the back of the backrest of the dental chair 1, the bandage is pulled to the position of the female buckle 5 on the lower opposite side of the shoulder body 3 according to the direction of the lower side route, and the inserting sheet 7 is inserted into the female buckle 5.

Step four: the strap with insert 6 on the other side of the shoulder body 3 operates the same. Thus, the straps are seen to overlap in an X-shape across the back of the back cushion of the dental chair 1.

Step five: the binding belt with the inserting sheet 7 is pulled out from one side of the arm of the shoulder body 3 of the head model to the back of the dental chair 1 and wound to the position of the female buckle 5 at the arm part of the other side of the shoulder body 3 of the head model, and the inserting sheet 7 is inserted into the female buckle 5. Thus, the binding bands are crossed and overlapped in a shape like a Chinese character 'mi' from the back of the back cushion of the dental chair 1.

Step six: the position of the dummy head model on the backrest of the dental chair 1 is properly moved, so that the clinical practice operator is most comfortable.

Step seven: the positions of the straps at six points, which are contacted with the edge of the backrest of the dental chair 1, of the straps are properly adjusted, so that the dummy head model is more balanced and stable on the backrest of the dental chair 1.

In the binding process, the middle of the binding band is not stopped when the binding band is pulled out, the binding band can not be pulled out when the binding band is pulled out for a certain length (about >40cm) and stopped in the middle according to the self-locking principle of the crimper, and the binding band can be pulled out again only when the binding band retracts to the bottom (about <40 cm).

After all bandage inserted sheets 7 are inserted into the respective female buttons 5, if the bandage is found to be not tightly bound, the bandage with the inserted sheets 7 is connected to one end of the pinched part near the notch of the shoulder body 3, and the bandage is pushed in the direction of the notch forcibly, so that the tightening degree of the bandage is increased.

So like this, the process that dental chair 1 was installed to imitative head mould finishes, when dismantling the head mould, only needs to press elastic switch 8 on the box, just can make box and inserted sheet dropout, and inserted sheet bandage 6 is in the human part of automatic retraction head mould under the torsional spring elastic action in box 4, and only inserted sheet 7 exposes in the outside, and the head mould can be relaxed, take off from the dental chair fast.
