Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model, and it is not used in restriction the utility model.
As Fig. 1 and Fig. 2 jointly shown in, a kind of paediatrics examination of mouth is hingedly connected together with support mouth apparatus, including middle part
Upper hinge bar 1 and lower hinge bar 2.
As shown in Figure 1, Figure 2 and Fig. 4 is jointly shown, and one end of upper hinge bar 1 is fixedly connected with upper connecting rod 8, and upper connecting rod 8
In the side of upper hinge bar 1 and perpendicular, upper connecting rod 8 is fixedly connected with upper pallet 3, and the lateral surface of upper pallet 1 is equipped with
With the matched upper alveolus 10 of upper teeth, be fixed with upper shell 11 made of silica gel in upper alveolus 10, upper hinge bar 1 it is another
End is fixed with lower supporting plate 6.
As Fig. 1 and Fig. 2 jointly shown in, one end of lower hinge bar 2 is fixedly connected with lower connecting rod 9, lower connecting rod 9 and upper company
Extension bar 8 is oppositely arranged, and lower connecting rod 9 is located at the side of lower hinge bar 2 and perpendicular, and lower connecting rod 9 is fixedly connected with subiculum
Plate 4, the lateral surface of lower pallet 4 be equipped with the matched lower alveolus of lower teeth, under being fixed with made of silica gel in lower alveolus
The other end of facing, lower hinge bar 2 is fixed with upper backup pad 5.
As Fig. 1 and Fig. 3 jointly shown in, backstop 7, backstop 7 are installed between upper backup pad 5 and lower supporting plate 6
Including sliding sleeve 71, rack gear 72, gear 73, ratchet 74 and pawl 75.The outboard end of sliding sleeve 71 is articulated on upper backup pad 6, rack gear
72 outboard end is articulated on lower supporting plate 5, rack gear 72 sliding be set to sliding sleeve 71 on, be fixed on sliding sleeve 71 support arm 76,
Support arm 77, support arm 76, support arm 77 end between be rotatably equipped with shaft 78,73 He of gear is fixed in shaft 78
Ratchet 74, gear 73 are engaged with rack gear 72, and the side of ratchet 74 is equipped with pawl 75, and pawl 75 is rotatablely installed on sliding sleeve 71.
In use, upper shell 11 is sheathed in upper teeth, lower shell is sheathed in lower teeth, upper shell 11 and lower shell
