Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and should not be understood as to the utility model
Limitation.
Below with reference to the accompanying drawings the guiding for oral cavity CBCT device according to the utility model first aspect embodiment is described
Structure 10.
As shown in Fig. 1-Figure 12, according to the guide frame 10 for oral cavity CBCT device of the utility model embodiment, packet
It includes: guide holder 100 and at least one rolling assembly 200.
Specifically, guide holder 100 vertically extends, guide holder 100 has connected mounting portion 110 and guide part
120.The column of oral cavity CBCT device is placed along the vertical direction, and guide holder 100 is installed on oral cavity CBCT device by mounting portion 110
Column on.Rolling assembly 200 is installed on guide part 120, and rolling assembly 200 has rolling surface 201, and rolling surface 201 is equipped with can
The rolling element 202 of rolling, rolling assembly 200 are configured to roll by the height adjustment column of rolling element 202 and oral cavity CBCT device
It moves to be connected and be moved up and down with steering level adjustable column.
In this way, height adjustment column is in rolling contact with rolling assembly 200, so as to limit to height adjustment column
While (for example, in left and right directions with front-rear direction upper limit), installation accuracy is reduced, improves flexibility, also, due to height
It is rolling friction between adjustable column and rolling assembly 200, coefficient of friction is small, and the service life is long.
In short, not only having and leading according to the guide frame 10 for oral cavity CBCT device of the utility model embodiment
To function, and assembly precision requirement is low, error permission is big, rolling resistance is small, at low cost, the service life is long.
Some embodiments according to the present utility model, as shown in figs. 1,2 and 6, rolling surface 201 are equipped with holding tank 203,
Rolling element 202 is rollably located in holding tank 203, and a part of rolling element 202 protrudes from rolling surface 201 to adjust with height
Segmented column is in contact.In this way, height adjustment column is steady, smooth compared with the rolling between rolling assembly 200, and rolling element 202
It is more firm to assemble.
Further, as shown in Fig. 1-Fig. 3, Fig. 6, Fig. 8 and Figure 10, rolling element 202 and holding tank 203 are respectively multiple,
Multiple rolling elements 202 cooperate correspondingly with multiple holding tanks 203, that is, are equipped with a rolling element in each holding tank 203
202, in this way, guiding is more steady, it is conducive to improve error permission, reduces rolling resistance.
It is appreciated that multiple holding tanks 203 can be arranged at (i.e. the moving direction of height adjustment column) interval along the vertical direction,
It is longer to be oriented to stroke.Certainly, multiple holding tanks 203 may be arranged in multiple rows of, and the utility model does not make special limit to this
It is fixed.
In some embodiments of the utility model, rolling surface 201 be it is parallel to each other and/or vertically disposed multiple, often
A rolling surface 201 is equipped with holding tank 203, and rolling element 202 is multiple, multiple rolling elements 202 and multiple 203 1 a pair of holding tanks
It answers.Here, " rolling surface 201 be parallel to each other and/or vertically disposed multiple " it is to be understood that multiple rolling surfaces 201 that
This is arranged in parallel, alternatively, multiple rolling surfaces 201 are arranged substantially perpendicular to each other, or, multiple rolling surfaces 201 include parallel to each other
Rolling surface 201 and rolling surface 201 perpendicular to one another.
For example, multiple rolling surfaces 201 are each perpendicular to left and right directions or multiple rollings after guide frame 10 is installed on column
Face 201 is each perpendicular to front-rear direction；For another example, after guide frame 10 is installed on column, a part in multiple rolling surfaces 201 is hung down
Directly in left and right directions and another part is each perpendicular to front-rear direction.
As a result, when rolling surface 201 is perpendicular to left and right directions, height adjustment column can be limited in the lateral direction
Position；When rolling surface 201 is perpendicular to front-rear direction, height adjustment column can be limited in the longitudinal direction；It hangs down when existing
Directly when the rolling surface of left and right directions 201 has perpendicular to rolling surface 201 in the front-back direction again, it can distinguish in left and right directions with before
Height adjustment column is limited in rear direction.
Optionally, shown in as shown in Figure 1, Figure 2, Fig. 4, Fig. 6, Fig. 7, Fig. 9 and Figure 11, rolling surface 201 includes vertical and connected
First rolling surface 204 and the second rolling surface 205, wherein the first rolling surface 204 hangs down perpendicular to front-rear direction, the second rolling surface 205
Directly in left and right directions.First rolling surface 204 is equipped with the first adaptation groove 206 and the second rolling surface 205 is equipped with the second adaptation groove 207,
Holding tank 203 is limited jointly by the first adaptation groove 206 and the second adaptation groove 207, that is, the first adaptation groove 206 and the second adaptation
Slot 207 is penetrated through so that holding tank 203 is collectively formed.
For example, height adjustment column is respectively arranged on the left side and the right side a guide frame 10, guiding knot positioned at left side
There are two rolling surfaces 201 for the tool of rolling assembly 200 of structure 10, and the first rolling surface 204 of described two rolling surfaces 201 is in front-rear direction
On be disposed opposite to each other, the second rolling surface 205 of described two rolling surfaces 201 towards right side be arranged；Guide frame positioned at right side
There are two rolling surfaces 201 for 10 tool of rolling assembly 200, and the first rolling surface 204 of described two rolling surfaces 201 is in the longitudinal direction
It is disposed opposite to each other, the second rolling surface 205 of described two rolling surfaces 201 is arranged towards left side.
In this way, two guide frames 10 in left and right directions limit height adjustment column on front-rear direction, automatic school
Straight height adjustment column, balances lean forward torque and moment resulting from sidesway, so that height adjustment column can only be moved smoothly along the vertical direction
It is dynamic.
It should be noted that particular number and position of the utility model for the rolling assembly 200 of each guide frame 10
It sets and is not particularly limited, the rolling assembly 200 of each guide frame 10 can be for one or multiple.
Advantageously, as shown in Fig. 1-Fig. 4 and Fig. 6-Figure 11, rolling element 202 is sphere, and the first adaptation groove 206 and second is suitable
One cross sectional shape in slot allocation 207 is major arc, it will be understood that the central angle of " major arc " is greater than 180 degree, can so guarantee
Rolling element 202 is protruded from holding tank 203 without departing from holding tank 203.For example, the cross sectional shape of the first adaptation groove 206 is
Rectangle, the cross sectional shape of the second adaptation groove 207 are major arc, that is, holding tank 203 is made of a part of round hole, and is accommodated
The depth of slot 203 is less than the diameter of round hole.
