Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
Referring to fig. 1 to 3, a surface profile measuring tool 100 according to an embodiment of the present invention is illustrated.
The surface measuring tool 100 includes a first scale 10 and a second scale 20.
The first scale 10 includes a first disk 11 and a first link 12 connected to each other, the first disk 11 is provided with angle measuring graduation lines 111, the first link 12 is provided with a first center line L1 for aiming at a face target point, and an extension line of the first center line L1 passes through a first center O1 of the first disk 11.
Here, the "first link 12 is provided with a first central line L1 for aiming at the face target point" means that the first central line L1 is used for the positioning of the face target point so as to achieve the auxiliary measurement, and the first central line L1 is a straight line.
In addition, the "angle scale 111" is a structure similar to a protractor, and the angle scale 111 has a plurality of scales for representing a plurality of different angles.
The second scale 20 includes a second disc 21 and a second link 22 connected to each other, the second disc 21 has a reading line N passing through a second center O2 of the second disc 21 and cooperating with the protracting scale 111, the second link 22 has a second center line L2 for aligning with a facial target point, and an extension line of the second center line L2 passes through the second center O2.
Here, the "second link 22 is provided with a second central line L2 for aiming at the face target point" means that the second central line L2 is used for positioning of the face target point for auxiliary measurement, and the second central line L2 is a straight line.
The first center O1 and the second center O2 cooperate with each other to rotatably connect the first disk 11 and the second disk 21.
It should be noted that the "facial target point" refers to some reference points located on the face, and a facial form measurement result can be obtained by measuring a relative positional relationship between a plurality of reference points, and the facial form measurement may be an angle measurement, or a measurement of whether a certain facial target point is located at an ideal position, so that the medical staff can give a subsequent plastic suggestion according to the facial form measurement result of the patient, and of course, the facial form measurement may also be in other measurement forms.
In the present embodiment, when the surface shape is measured by an angle, the angle scale 111 is located on the first disc 11 such that the angle scale 111 and the first center line L1 have a fixed relative positional relationship, and the reading line N is located on the second disc 21 such that the reading line N and the second center line L2 have a fixed relative positional relationship, when the second scale 20 rotates relative to the first scale 10 to achieve the surface shape measurement (i.e. the first center line L1 and the second center line L2 both correspond to the face target points), the current angle between the first center line L1 and the second center line L2 can be intuitively obtained through the current scale of the angle scale 111 indicated by the reading line N, and the measurement result of the surface shape can be obtained.
When the measurement of the face shape is a measurement of whether a certain face target point is located at an ideal position, a plurality of face target points can be located in advance by using the first central line L1 or the second central line L2, and then whether the face target point is located at the ideal position is measured according to the relative position relationship between other face target points and the first central line L1 or the second central line L2.
It can be seen that the surface shape measuring tool 100 of the present embodiment has a simple structure and is convenient to operate, the surface shape measuring operation can be simplified, and the accuracy and intuitiveness of the measurement result can be improved.
In practice, other areas of the surface type measuring tool 100 may be utilized to align the target point, and the accuracy and reliability of the measurement may be improved by multi-point positioning, for example, but not limited to, the first circle center O1 or the intersection point of the first circular disc 11 and the first center line L1 is used to align the target point.
In the present embodiment, the outer contour of the first disk 11 and the outer contour of the second disk 21 always overlap each other.
Here, the outer contour of the first disc 11 and the outer contour of the second disc 21 are both circular, the size of the first disc 11 is the same as the size of the second disc 21, and the first circle center O1 and the second circle center O2 are overlapped to form a rotation center, so that when the second disc 21 rotates to an arbitrary position relative to the first disc 11, the outer contour of the first disc 11 and the outer contour of the second disc 21 are overlapped with each other in the overlapping direction of the first scale 10 and the second scale 20.
It can be understood that when the second scale 20 rotates relative to the first scale 10, the first link 12 and the second link 22 are mutually staggered or overlapped, and at this time, the outer contour of the first disk 11 in the "outer contour of the first disk 11 and the outer contour of the second disk 21 always overlap" refers to the outer contour of the other region of the first disk 11 except for the region connected with the first link 12, and similarly, the outer contour of the second disk 21 refers to the outer contour of the other region of the second disk 21 except for the region connected with the second link 22.
In addition, the first link 12 has the same size as the second link 22, and the first central line L1 coincides with the second central line L2 when the first link 12 and the second link 22 completely overlap.
That is, the outer contour of the first scale 10 is the same as the outer contour of the second scale 20, when the surface type measuring tool 100 is in the folded state, the first scale 10 is overlapped with the second scale 20, the outer contour of the first disk 11 is completely overlapped with the outer contour of the second disk 21, and the outer contour of the first link 12 is completely overlapped with the outer contour of the second link 22, so that the surface type measuring tool 100 can be conveniently stored and used.
In the present embodiment, the first scale 10 and the second scale 20 are transparent scales, so that the current scale of the reading line N can be easily obtained, and the first center line L1 and the second center line L2 can be easily aligned with the target point of the face.
In this embodiment, the first disk 11 of the first scale 10 and the first link 12 are integrally formed, and the first disk 11 and the first link 12 are in a rounded transition, so as to prevent the first scale 10 from scratching the face of the patient during use.
The diameter of the first disc 11 is larger than the first width of the first link 12 in the first direction perpendicular to the extending direction of the first center line L1, that is, the first scale 10 is substantially racket-shaped, so as to facilitate the holding operation of the first scale 10.
The outer contour of the first link 12 is of a half-track type.
Here, the "half track type" means that the first width of the first link 12 is first maintained in a direction from the first disc 11 to the first disc 11, and then, when reaching the end of the first link 12 away from the first disc 11, the first width is gradually decreased, and the end is semicircular.
In addition, in the stacking direction of the first scale 10 and the second scale 20, the first scale 10 has a first surface and a second surface which are oppositely arranged, the first surface and the second surface are continuous planes, that is, the thickness of each region of the first scale 10 is equal, and no step portion exists on the upper surface and the lower surface of the first scale 10, so that the relative rotation between the first scale 10 and the second scale 20 is smoother.
Similarly, in the present embodiment, the second disk 21 and the second link 22 are integrally formed, and the second disk 21 and the second link 22 are in round transition.
The diameter of the second disc 21 is larger than a second width of the second link 22 in a second direction perpendicular to the extending direction of the second central line L2.
The outer profile of the second link 22 is of a half-track type.
The second scale 20 has a third surface and a fourth surface that are disposed opposite to each other, and both the third surface and the fourth surface are continuous planes.
In the present embodiment, the first through hole 13 is disposed at the first center O1 of the first disk 11, the second through hole 23 is disposed at the second center O2 of the second disk 21, and the first through hole 13 and the second through hole 23 are connected by the rivet 30, on one hand, the rivet 30 can prevent the first disk 11 and the second disk 21 from separating from each other, on the other hand, the rivet 30 can realize the rotational connection between the first disk 11 and the second disk 21, and the rivet 30 can be, for example, a metal member, but not limited thereto.
The center of the rivet 30 is a through hole 31, which facilitates the alignment or observation of the target point on the face through the through hole 31.
The working principle of the surface type measuring tool 100 will be described in detail below.
In the present embodiment, taking the measurement of the surface type as an example of the measurement of the angle, the reading line N and the angle scale line 111 are configured as follows: when the first circle center O1 is aligned with the first face target point, the first center line L1 is aligned with the second face target point, and the second center line L2 is aligned with the third face target point (i.e., the face type measuring tool 100 is in the open state), the current scale of the reading line N at the angulation scale line 111 is read to represent the current angle between the first center line L1 and the second center line L2.
That is to say, first, the positioning portions (including the first center O1, the first center line L1, and the second center line L2) of the surface type measuring tool 100 are aligned to the target points of the plurality of faces to be measured, at this time, the second scale 20 rotates at a certain angle relative to the first scale 10, the rotation process of the second scale 20 drives the reading line N to move at the angle measurement scale line 111, and the current scale indicated by the reading line N is the current included angle between the first center line L1 and the second center line L2.
Specifically, the coverage area of the angle measuring graduation line 111 is a semicircular area connected with the first link 12, that is, the angle measuring graduation line 111 only covers a half area of the first disk 11.
The protracting graduation mark 111 comprises a first radius R1 parallel to the first middle line L1 and two second radii R2 perpendicular to the first middle line L1, the first radius R1 cooperates with the two second radii R2 to form two graduation regions P, and the two graduation regions P are symmetrically arranged relative to the first radius R1.
Here, the first radius R1 is defined as a first scale region P1 in the clockwise direction, the first radius R1 is defined as a second scale region P2 in the counterclockwise direction, a first scale region P1 in the shape of a right-angled fan is formed between the first radius R1 and the clockwise second radius R2, and a second scale region P in the shape of a right-angled fan is formed between the first radius R1 and the counterclockwise second radius R2.
In addition, the phrase "the two scale areas P are symmetrically disposed with respect to the first radius R1" means that the two scale areas P are not only symmetrical in coverage, but also symmetrical in scale, so that the current scale of the corresponding reading line N can be obtained no matter the second scale 20 rotates clockwise or counterclockwise with respect to the first scale 10.
In actual operation, when the second scale 20 is rotated in the third direction (clockwise or counterclockwise) with respect to the first scale 10, the current scale is obtained by the reading line N in the scale region P on the third direction side of the first radius R1.
That is, when the second scale 20 is rotated clockwise with respect to the first scale 10, the current scale of the reading line N in the first scale region P1 is read; when the second scale 20 is rotated counterclockwise relative to the first scale 10, the current scale of the reading line N in the second scale region P2 is read, and thus, the reading of the current scale can be facilitated.
The second disc 21 comprises 0 ° readings N1 and N2 parallel to the second centerline L2 and 90 ° readings N3 and N4 perpendicular to the second centerline L2, i.e. the 0 ° readings N1 and N2 are coincident with the extension of the second centerline L2, and the 0 ° reading N1 is closer to the second centerline L2 than the 180 ° reading N2.
Here, the second disk 21 includes four reading lines, starting from the 0 ° reading line N1, and sequentially including the 0 ° reading line N1, the 90 ° reading line N3, and the 180 ° reading line N2 in a range of 180 ° in the clockwise direction, and similarly, starting from the 0 ° reading line N1, sequentially including the 0 ° reading line N1, the 90 ° reading line N4, and the 180 ° reading line N2 in a range of 180 ° in the counterclockwise direction.
When the 0 ° reading line N1 is located in the scale region P, the current angle is an acute angle, when the 90 ° reading lines N3, N4 are located in the scale region P, the current angle is a right angle or an obtuse angle, and when the 180 ° reading line N2 is located in the scale region P, the current angle is a straight angle.
The scale areas P comprise fan-shaped first circle of scales K1 and second circle of scales K2, in the third direction, the first circle of scales K1 is decreased progressively from 90 degrees to 0 degrees, and the second circle of scales K2 is decreased progressively from 180 degrees to 90 degrees, so that the scales of the two scale areas P are ensured to be symmetrical to each other.
Specifically, taking the first scale region P1 as an example, when the second scale 20 rotates clockwise by 30 ° relative to the first scale 10, the 0 ° reading line N1 is aligned with the scale displayed as "60" on the first circle of scales K1, and the obtained current scale is 30 ° (i.e., difference operation is performed by 90-60 ═ 30); when the second scale 20 is rotated 110 ° clockwise relative to the first scale 10, the 90 ° reading line N4 is aligned with the scale displayed as "160" on the second circle of scales K2, and the current scale is acquired as 110 ° (i.e. the difference and addition operation 180-.
It can be seen that, in the embodiment, by arranging two circles of scales and a plurality of reading lines, the included angle range of 0 to 180 degrees can be displayed in the first scale region P1 in the shape of a right-angle fan, so that the reading regions are more concentrated.
It will be appreciated that the face measurement tool 100 of the present embodiment may of course also exhibit an included angle of more than 180 °, where the current scale is the current scale based on 180 ° plus the reading line N in the second scale region P2.
In this embodiment, the facial target point is a nasion point, a nose tip point, a bead point of the upper lip, a sunken point of the lower lip, a bead point of the lower lip, a point in front of the chin, or a midpoint of a connecting line between two eyes, but not limited thereto.
