Abstract
An electron outer diameter measurer is provided, wherein a movable sensing contactor (2) is arranged in a movable sensing contactor guiding hole (1-1) of the body (1), two ends of which extends out of the hole. A restoring spring (3) is hitched on the movable sensing contactor (2), a limiting cover (6) is mounted on the export of the movable sensing contactor guiding hole (1-1) of the body (1), a locating rod (4) and a right locating rod (5) are separately mounted on the body (1), an inductor (7) is mounted on the body (1), and a digital processing displayer (8) is electric connected with the inductor (7). The utility model has the advantages that, the circle diameters with different sizes can be measured without changing the measuring tool's size, the measurement accuracy is high, and the measuring effect to the arc which loses the circle centre after damaged is better. In addition, the utility model is cabinet and portable and is convenient to carry.
Description
Technical field
The utility model relates to the surveying instrument field.Relate in particular to the outside diameter measuring instrument of circle.
Background technology
At present, the outside diameter measuring of circle is also continued to use ancient traditional approach and method, and diameter is big more, and required survey instrument is big more, needs to measure really, and survey instrument uses very inconvenient, and it is time-consuming to require great effort, and measuring accuracy can not get guaranteeing.
The utility model content
The purpose of utility model is exactly to provide a kind of electronics outside diameter measuring device at the above-mentioned deficiency of outside diameter measuring instrument of existing circle, it is made up of body 1, activity sensor contact 2, back-moving spring 3, left backstay 4, right backstay 5, limited cover 6, inductor 7, digital processing display 8, the intracardiac activity sensor contact pilot hole 1-1 that is provided with in body 1, activity sensor contact 2 is placed in the activity sensor contact pilot hole 1-1 of body 1, and stretch out outside the hole at its two ends; Back-moving spring 3 is enclosed within on the activity sensor contact 2, limited cover 6 is installed in the activity sensor contact pilot hole 1-1 exit of body 1, backstay 4 and right backstay 5 are installed in respectively on the body 1, and be symmetrically located at the and arranged on left and right sides of activity sensor contact 2, inductor 7 is installed on body 1, and be positioned at the below of activity sensor contact 2, digital processing display 8 is electrically connected with inductor 7.
The utility model has the advantages that: change the outside diameter measuring mode and the method for traditional circle, do not changed the survey instrument size, just can measure the circular diameter of different sizes, the measuring accuracy height, better for the arc measurement effect that loses the center of circle after the breakage.And small volume and less weight, easy to carry.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Embodiment
The intracardiac activity sensor contact pilot hole of opening in body, the activity sensor contact is placed in the activity sensor contact pilot hole of body, and stretch out outside the hole at its two ends.The activity sensor contact is cross, and back-moving spring is enclosed within on the activity sensor contact, and its upper end withstands on the cross cross bar of activity sensor contact, and the lower end is against on the body.Spacing cover screw is installed in the activity sensor contact pilot hole exit of body, be pressed on the cross cross bar of activity sensor contact, left side backstay is identical with right backstay planform, is installed on the body respectively, and is symmetrically located at the and arranged on left and right sides of activity sensor contact.Inductor is installed on body, is positioned at the below of activity sensor contact, and the digital processing display is electrically connected with inductor.
Principle of work: during measurement, tested circle is placed on the top of left backstay, right backstay and activity sensor contact, the sensor contact pressurized moves down, and limits sensor contact and no longer moves down until left backstay, right backstay, forms at any 3 and determines a circle.Circular arc with measured circle varies in size, the distance that the activity sensor contact moves down is just different, the activity sensor contact is also just different with the spacing of inductor, then the strong and weak degree of the signal sensed of inductor is just different, inductor is transferred to the digital processing display with the signal of induction thereupon, directly demonstrates the diameter data of measured circle after digital processing display treatment conversion.Its circuit working principle is similar to the principle of work of electronic platform balance.
