Utility model content
The purpose of this utility model is: provide a kind of structure simple, simple to operate, show in real time can draw radius of a circle by the adjustment of knob, conveniently adjust radius, overcome the inconvenience of too busy to get away ruler, and regulate a kind of dial plate of the tedious steps of radius automatically to measure formula compasses, to overcome the deficiencies in the prior art.
The utility model is achieved in that formula compasses measured automatically by a kind of dial plate; described dial plate is automatically measured formula compasses and is connected to form by the outer active shell of dial plate containment vessel, dial plate front casing, dial plate rear flank shell and dial plate from front to back; in dial plate rear flank, cover top portion is provided with adjusting knob and home button; baffle plate A, baffle plate B and radius gear adjuster is provided with between dial plate rear flank shell and the outer active shell of dial plate; described baffle plate A is connected with supporting leg A, baffle plate B is connected with legs B; supporting leg A is provided with compasses point, legs B is provided with mechanical pencil.
Described dial plate front casing is provided with dial plate, pointer driving shaft, dial plate is provided with scale mark.
Described adjusting knob is connected with radius gear adjuster with home button, and radius gear adjuster is connected with tuning drive gear by pointer driving shaft.
Described baffle plate A and baffle plate B can rotate around axle center at dial plate rear flank shell medial surface.
Described radius gear adjuster inside is gear structure.
Described dial plate side active shell is slided on the shell of dial plate rear flank by the drive of supporting leg A, legs B.
Owing to have employed technique scheme, compared with prior art, the utility model is regulated can be drawn radius of a circle by a radius adjustment, by regulating the adjustment rotated, regulate the size of radius, and utilize the principle of dial plate can draw radius of a circle by advantages such as tuning drive gear come that real-time synchronization is shown.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to restriction of the present utility model.
Embodiment of the present utility model: formula compasses measured automatically by a kind of dial plate, in described index dial structure, by the rotation of adjusting knob, motion transmission is inner to radius gear adjuster, the torque imported into exporting is changed in the inside of radius gear adjuster, and by baffle plate A and baffle plate B, moment of torsion is spread out of, and synchronously shown by gear driven pointer, in addition in index dial structure by the pressing of home button, the motion of radius gear adjuster inside can be driven simultaneously, equally the internal motion of generation is passed to outside by baffle plate A and baffle plate B, synchronously drive pointer to show by the motion of gear simultaneously.
The inside of described radius gear adjuster is that the change of the various gearratio of pinion that each varies in size is to the size of the output torque of the respective needs of the input torque and baffle plate and pointer that change adjusting knob.The inside of described radius gear adjuster drives the motion of the spring of its inside by the effect of home button, realized the playback of pointer and synchronous 0 scale of baffle plate by the pulling force of spring.
Described left and right supporting leg respectively by the restriction of left baffle, fixes the position of supporting leg in the anglec of rotation.
In described index dial structure, spherical groove is provided with in the connection edge of dial plate rear flank shell and dial plate front casing, be that the corresponding section of the spherical groove at the dial plate front casing edge that dial plate rear flank shell edge is corresponding has outstanding spherula simultaneously, realize the connection of dial plate front casing and dial plate posterior edge.Be in like manner principle of uniformity method in the connection of dial plate containment vessel and dial plate front casing.
In described index dial structure, dial plate front casing is transparent material, then with dial plate rear flank shell, and dial plate containment vessel, and dial plate active shell forms an airtight housing.Described dial plate side active shell being connected and fixed on the shell of dial plate rear flank by slip rail groove.
Described supporting leg A, legs B, be connected through the hinge together, is not non-ly in addition fixed on above baffle plate A, baffle plate B, driven the motion of supporting leg A by the motion of baffle plate A, driven the motion of legs B by the motion of baffle plate B.
Mechanical pencil adopts the structure of one in legs B.
During use, turn clockwise adjusting knob, it is inner that motion transmission is entered radius gear adjuster by adjusting knob, the gear of radius gear adjuster inside is by the change of different gearratios, motion is transferred in real time on baffle plate A and baffle plate B, baffle plate A drives the motion of supporting leg A, baffle plate B drives the motion of legs B, the relation proportional according to phase triangle corresponding sides, radius gear is according to the spacing of baffle plate A and baffle plate B and the ratio can drawing radius of a circle, real-time synchronization regulates the moment of torsion of tuning drive gear, and the scale mark above synchronous dial plate is shown.Then with compasses nib for the center of circle, rotating shaft, utilize the nib of mechanical pencil to give picture circle.
After using, pin home button not put, home button touches the spring of radius gear adjuster inside, spring drives the gear of radius gear adjuster inside to do playback gyration, drive tuning drive gear and baffle plate A, baffle plate B to carry out the playback of real-time synchronization simultaneously, baffle plate A drives the playback of supporting leg A simultaneously, and baffle plate B drives the playback of legs B.Decontrol home button, compasses the automatic recovery is complete.
