Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 2 schematically shows a kind of adjustable type dental impression tray of embodiment according to the present utility model.Such as
Shown in figure, which includes double of pallet 1, handle 2 and fixing component.
In this application, on the basis of location fix when being used by pallet, outside is to be directed toward extrabuccal direction, and inside is
It is directed toward intraoral direction.
There are two double of pallets 1, is arranged symmetrically to form the shape that can cover dental arch, each double of pallet 1 is solid
Surely there is a corresponding handle 2.Each double of pallet 1 is substantially fan-shaped (can also be on fan shaped foundation plus fillet or other tune
It is whole), central angle α, 90 ° of α≤180 ° <, to better cover dental arch.But the shape of double of pallet 1 it is non-limiting in this,
In other embodiments, it is also possible to truncation annular as shown in Figure 8 (annular interception a portion is formed by shape), only
It wants that dental arch can be covered and for stamp use.
Each double of pallet 1 includes bottom plate 11 and the arcuate blocking piece 12 for being trapped among the outside of bottom plate 11, for clear signal,
The thickness of arcuate blocking piece 12 in attached drawing has done exaggeration processing.Two double of pallets 1 overlap, with the center of the overlapping
Position is that hinge joint 13 is hinged, and can mutually be rotated.Due to the part overlapped in two double of pallets 1,
In double of pallet can be stacked on another double of pallet, the arcuate blocking piece on double of pallet being located above can cover entirely
The outside of bottom plate, and the arcuate blocking piece on underlying double of pallet accordingly shortens, double of pallet for being only capable of covering top does not have
Have a part of overlapping, those skilled in the art can the setting positions and dimensions as the case may be to the arcuate blocking piece 12 be adjusted,
As long as can be for stamp use.
When two double of pallets 1 are rotated with hinge joint 13 for fulcrum, the width W and depth D of pallet can be changed.Such as figure
Shown in 3 and 4, effect picture that respectively double of pallet 1 is rotated towards both direction.It is rotated accordingly, due to two double of pallets 1
When, lap will increase or reduce, in the case where increase (as shown in Figure 3), in required rotation angle range, and position
Double of pallet in lower section needs reserved certain space, prevents double of pallet being located above from being kept off by the arch of double of lower section pallet
Plate blocks and can not achieve rotation.In some embodiments, to prevent from occurring between arcuate blocking piece wide arc gap to cause to print
Mold materials leaks, and can reduce the gap between arcuate blocking piece, the direction for only allowing double of pallet mutually narrowed shown in Fig. 4
Upper rotation, without allow its shown in fig. 5 the direction mutually expanded on rotate.
Preferably, which further includes the first groove 121, the first Extendible flake 122 and the first screw 123.This
One groove 121 is formed in the top of arcuate blocking piece 12, which is arranged in the first groove 121, can stretch out
To outside the first groove 121, to increase the height H of arcuate blocking piece 12, as shown in Figure 5.First screw 123 is outside arcuate blocking piece 12
Side is inserted into first groove 121, and the first Extendible flake 122 is withstood the inner wall of the first groove 121 and fixes it.Further
Ground, first groove 121 have multiple, are sequentially distributed along the arcuate blocking piece 12 of two double of pallets 1, in other embodiments
In, multiple first Extendible flakes can also be arranged in first groove with only one the first coherent groove in each double of pallet.?
In the present embodiment, there are five first grooves 121, respectively corresponds five different zones on arcuate blocking piece 12, the region (or
One groove 121) between respectively using the position of bilateral canine tooth, the second premolar teeth and third molar as separation (each of Fig. 5
The position of one groove is only substantially illustrated, not accurate dimension), in order to accordingly adjust arcuate blocking piece according to different tooth body structures
The height H of five different zones on 12.
Preferably, the bottom plate 11 of each double of pallet 1 further includes the second groove 111, the second Extendible flake 112 and the second screw
113.Second groove 111 is formed in the inside of bottom plate 11, which is arranged in the second groove 111, can
It extend out to outside the second groove 111, to increase the depth D of bottom plate 11, as shown in Figures 6 and 7.Second screw 113 is from bottom plate 11
Bottom is inserted into second groove 111, and the second Extendible flake 112 is withstood the inner wall of the second groove 111 and fixes it.
The fixing component is used to two handles 2 be fixed to each other in a selected angle.Specifically, which includes
Fixinig plate 31, fixing screws 32 and fixture nut (fixture nut is not drawn into figure).The fixinig plate 31 is strip, fixinig plate
The movable span 311 there are two bar shaped, the corresponding handle 2 of each movable span 311 are set on 31.Each fixing screws 32 pass through one
Fixinig plate 31 is mounted on two handles 2 by movable span 311 and corresponding handle 2.Move two handles 2 make two to day care
When disk 1 mutually rotates, which can slide in movable span 311, after required rotation angle is arrived in adjusting, will consolidate
Determine nut to be tightened on screw from 2 back side of handle, fixinig plate 31 can be pressed abd fixed on handle 2, so that two handles 2 are logical
It crosses fixinig plate 31 to be fixed to each other, achievees the purpose that fix two double of pallets 1.In other embodiments, it can also be used
His mode fixes two handles, to achieve the purpose that fix two double of pallets, such as a column fixation hole is arranged on handle, adjusts
After whole good handle position, fixinig plate is placed at corresponding fixation hole, screws fixing screws and fixture nut then will consolidate
Stator is fixed with handle.
The dental impression tray of the utility model can adjust its width, depth and height on three-dimensional, applicable
In a variety of dental arch situations of different patients, medical efficiency is improved.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, or to above-mentioned technical proposal
It is freely combined, these are all within the protection scope of the present invention.
