Abstract
A joint angle measuring ruler comprises an angle measuring arm and a length measuring arm, wherein the angle measuring arm adopts a rectangular plate body structure with a semicircle arranged at one end, the center part of the semicircular end of the angle measuring arm is hinged together with the length measuring arm through a rotating shaft; a length datum line and an angle datum line are respectively arranged in the center parts of both the angle measuring arm and the length measuring arm in the length direction; length scales are formed on the lower edge of the length measuring arm, and a 360-DEG angle scales are formed on the ruler surface of the semicircular end of the angle measuring arm along the circumference thereof. The joint angle measuring ruler provided by the utility model has the benefits as follows: the device is convenient to use, has a simple structure and is convenient to manufacture; since the two measuring arms of the measuring scale are coaxially connected, the rotating is convenient, and measuring accuracy can be ensured to the utmost extent; and the joint angle measuring ruler is convenient to be used in community rehabilitation, hospital rehabilitation and school rehabilitation teaching.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of joint angles dip stick that is applicable to clinical rehabilitation evaluation and rehabilitation teaching.
Background technology
At present, in clinical rehabilitation and rehabilitation teaching process, for the variation of measuring joint angles all is to use the joint angles protractor, but existing joint angles protractor all comprises fixed arm and transfer arm, when measuring joint angles, generally is after fixed arm is fixed, realize the measurement of angle by promoting transfer arm, and this measurement all is to rely on vision to do reference, and precision is low, occurs measurement error easily.
The utility model content
This utility model is at the low defective of existing joint angles protractor certainty of measurement, provides a kind of and can improve joint angles accuracy of measurement, joint angles dip stick easy to use.
Realize the foregoing invention purpose by the following technical solutions: a kind of joint angles dip stick, comprise angular surveying arm and linear measure longimetry arm, described angular surveying arm is that an end is the rectangular slab body structure of semi arch, and the position, the center of circle of the semicircle end of this angular surveying arm is hinged with rotating shaft and linear measure longimetry arm; Central part on described angular surveying arm and the linear measure longimetry arm, be respectively arranged with length standard line and angle reference line along its length direction; The bottom of linear measure longimetry arm is provided with the length scale, and its circumference of chi face upper edge of the semicircle end of angular surveying arm is provided with the angle index of 360 degree.
Adopt technique scheme, compare with present standing crop hornwork, the beneficial effects of the utility model are: this device is easy to use, and is simple in structure, is convenient to make; Because two coaxial connections of gage beam of dip stick, the convenient rotation can guarantee the accuracy of measuring to greatest extent; Convenient use in community-based rehabilitation, hospital rehabilitation, school's rehabilitation teaching.
As preferred version: rotating shaft is arranged on the middle position at 1/3rd places of linear measure longimetry arm.The angle index that the angle reference line is aimed at is 0 degree.
As preferred version: linear measure longimetry arm and angular surveying arm are transparent material and are made.Scale on linear measure longimetry arm and the angular surveying arm all is arranged on the chi face of the same side.
As preferred version: linear measure longimetry arm and angular surveying arm are metal plate.Be provided with length scale and length standard line on the chi face of linear measure longimetry arm both sides; Be provided with angle index and angle reference line on the chi face of angular surveying arm both sides.
As preferred version: angular surveying arm and linear measure longimetry arm are respectively the plate body structure of length 20cm, width 4.5cm, thickness 1mm.
Description of drawings
Fig. 1 is this utility model overall structure sketch map.
Fig. 2 is plan structure sketch map of the present utility model.
Among the figure: linear measure longimetry arm 1, length standard line 2, length scale 3, rotating shaft 4, angle index 5, angular surveying arm 6, angle reference line 7.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is described further.
Referring to accompanying drawing 1-2, this novel disclosed this joint angles dip stick comprises angular surveying arm 6 and linear measure longimetry arm 1.Angular surveying arm 6 is that an end is the rectangular slab body structure of semi arch, and the position, the center of circle of its semicircle end is hinged with rotating shaft 4 and linear measure longimetry arm 1, can realize between the two freely rotating.Rotating shaft 4 is arranged on the middle position at 1/3rd places of linear measure longimetry arm 1.Central part on angular surveying arm 6 and the linear measure longimetry arm 1, be respectively arranged with length standard line 2 and angle reference line 7 along its length direction, wherein the angle reference line 7 on the angular surveying arm 6 runs through the length direction of whole angular surveying arm.The bottom of linear measure longimetry arm 1 is provided with length scale 3, and its circumference of chi face upper edge of the semicircle end of angular surveying arm 6 is provided with the angle index 6 of 360 degree.For being convenient for measuring, the angle index that the angle reference line is aimed at is 0 degree, is benchmark is done the 0-180 degree of two symmetries along clockwise direction with counter clockwise direction angle mark distribution with this graticule then.
Scheme 1: linear measure longimetry arm 1 and angular surveying arm 6 are transparent material and are made.Scale on linear measure longimetry arm and the angular surveying arm all is arranged on the chi face of the same side.Because it is transparent that gage beam is, any one side of this joint angles dip stick can be measured.
Scheme 2: linear measure longimetry arm and angular surveying arm are metal plate.So, be provided with length scale 3 and length standard line 2 on the chi face of linear measure longimetry arm 1 both sides; Be provided with angle index 5 and angle reference line 7 on the chi face of angular surveying arm 6 both sides, like this, also can realize any planar survey of this joint angles dip stick.
As preferred version: angular surveying arm and linear measure longimetry arm are respectively the plate body structure of length 20cm, width 4.5cm, thickness 1mm.
When reality was used, length standard line and angle reference line by the rotational angle gage beam, made the edge of angular surveying arm to the locating tab assembly thing as line of reference, and the angle index that the length standard line on the linear measure longimetry arm is aimed at is joint angles.
