Abstract
The utility model relates to a cervical vertebra measuring device, mainly used to measure the lateral bending distance of the cervical vertebra of the human body. The utility model comprises a vertical location ruler and a lateral level measuring ruler. A bit shift inducer is connected with the location ruler; a cross measuring ruler jack is arranged on the bit shift inducer; the measuring ruler penetrates through the measuring ruler jack to moveably connect with the bit shift inducer; a sensing element for inducting the bit shift of the measuring ruler is arranged on the bit shift inducer; a digital displayer for displaying the length of the bit shift of the measuring ruler is arranged on the bit shift inducer. The users put the front end of the lower part of the location ruler to the seventh cervical vertebra position of the measured one, and move the measuring ruler from the dead-center position to forward and put the top of the front end on the top part of the cervical vertebra, and then the length displayed on the digital displayer is the distance of lateral bending distance of the cervical vertebra. The measuring device can exactly measure the lateral bending degree of the cervical vertebra and it also has the advantages of convenient operation and clear data display.
Description
Technical field
This utility model relates to a kind of gauge, is a kind of gauge of measuring cervical vertebra horizontal curvature distance that is mainly used in specifically.
Background technology
Cervical vertebra horizontal curvature degree can with its top to the bottom horizontal range of (or on the vertebra other suitable position) weigh, there is not to measure specially the gauge of this horizontal range under the prior art, use universal measurement instrument (for example ruler), (be used as the cervical vertebra bottom of measuring basic point or other positions of vertebra with respect to the level at cervical vertebra top to the position) can't accurately be determined because the horizontal survey starting point, it is bigger not only to measure difficulty, and measurement error is also very big, therefore need a kind of gauge of special use, accurately and easily measure so that carry out.
The utility model content
For overcoming the above-mentioned defective of prior art, this utility model provides a kind of cervical vertebra measuring instrument, uses this measuring instrument can accurately measure cervical vertebra horizontal curvature degree easily.
This utility model realizes that the technical scheme of above-mentioned purpose is: a kind of cervical vertebra measuring instrument, comprise perpendicular positioning chi and transverse horizontal dip stick, be connected with a displacement sensor on the described positioning rule, described displacement sensor is provided with cross measure chi jack, described dip stick passes described dip stick jack, move connection with described displacement sensor, described displacement sensor is provided with the sensing element of the described dip stick displacement of induction, and is provided with the character display that shows the dip stick shift length.
Operation principle of the present utility model is: the front end of positioning rule lower end is placed on the position, place that is used as the 7th joint vertebra of measuring basic point or other suitable location of vertebra, make positioning rule keep vertical, dip stick is placed on dead-center position, and (its front end is positioned at the identical horizontal level of the front end of positioning rule lower end, perhaps be positioned at other as the horizontal displacement position at zero point) on, character display is returned zero, promote dip stick forward, make its front end withstand on the position, place at cervical vertebra top just, at this moment the character display data presented is exactly the shift length of dip stick from dead-center position, and just the cervical vertebra top is with respect to the horizontal curvature distance of cervical vertebra bottom (or other basic point positions).
The beneficial effects of the utility model are: can accurately measure the horizontal curvature degree of cervical vertebra, and easy to operate, data show is clear.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, the cervical vertebra measuring instrument that this utility model provides comprises perpendicular positioning chi 1 and transverse horizontal dip stick 3, be connected with a displacement sensor 2 on the described positioning rule, described displacement sensor is provided with cross measure chi jack, described dip stick passes described dip stick jack, move connection with described displacement sensor, described displacement sensor is provided with the sensing element of the described dip stick displacement of induction, and is provided with the character display 7 that shows the dip stick shift length.
The two ends up and down of described positioning rule 1 all can be provided with the horizontal segment 12 that extends forward, the front end of described horizontal segment is provided with longitudinal register wheel 11, the axle 10 of described locating wheel is fixedly mounted on the front portion of positioning rule horizontal segment, described locating wheel is enclosed within on the corresponding axle, with described axle matched in clearance, two ends foremost about the forward edge of described locating wheel laid respectively at described positioning rule, locating wheel with the positioning rule lower end during measurement is attached on the human body specific part that is used as basic point, realizes the location to measuring instrument.Because locating wheel can adopt plastics or other macromolecular materials to make, its edge is slick and sly, and can rotate by the relative localization chi, adopts this locating wheel to contact with human body, can avoid bringing sense of discomfort and damage to the gauger.
The front end of described dip stick 3 can be provided with contact block 8, described contact block can adopt plastics or other macromolecular materials to make, and be fixed on the front end of the dip stick main body that is made of metal by modes such as bolt or screws, the front end of contact block can be curved, adopt this contact to contact with human body, can avoid bringing sense of discomfort and damage to the measured, described dip stick rear end also can be provided with identical contact block 4, so that manually spur dip stick, identical contact block structure also helps the minimizing mould, convenient production.
Described displacement sensor 2 can be fixedly connected with positioning rule 1, and be positioned at the position that mid point is departed from the positioning rule middle part, make to be positioned at and move the induction apparatus positioning rule length difference of both sides up and down, because positioning rule all can be used for locating on human body in two ends up and down, on a measuring instrument, just can provide two kinds of differing heights from the anchor point to the measurement point like this, to adapt to different measured person's different cervical vertebra length.
Described displacement sensor 2 can move connection with positioning rule 1, specific implementation can be that perpendicular positioning chi jack is set on the displacement sensor, by this positioning rule jack sleeve on positioning rule, can be provided with set bolt on the positioning rule jack sidewall, the screw of described set bolt penetrates described positioning rule jack sidewall, during use according to the concrete length of the measured cervical vertebra, regulate the position of displacement sensor on positioning rule, when the positioning rule lower end is contacted with basic point, dip stick is positioned at same level height with the cervical vertebra top just, bolt is tightened, the afterbody of set bolt withstands on the positioning rule, displacement sensor and positioning rule are fixed together, and displacement sensor moves when avoiding operating.
Described displacement sensor 2 can be provided with back zero key 5, long measure shift key 9 and on ﹠ off switch 6, uses with convenient.
