Abstract
The utility model relates to a multi-purpose ruler, which aims to solve the problems of curve measurement and precision measurement. The multi-purpose ruler is mainly composed of an operating wheel, a long shaft, a small gear, a measurement gear, a short shaft, a big gear, a rack bar ruler, reading numbers and scales. The utility model is characterized in that the lower end of the operating wheel is connected with the center of the upper end of the small gear by the long shaft; the circumference of the small gear is meshed and arranged on the circumference of the big gear; the upper end of the middle of the big gear is arranged on the lower end of the measurement gear; the circumference of the measurement gear is meshed and arranged on teeth of the rack bar ruler. The utility model can be produced in batches for supplying the requirements of educational circles by utilizing equipment of a student appliance factory.
Description
(1) technical field:
The utility model relates to a kind of multipurpose ruler, divides the technical field that belongs to the ruler group by International Patent Classification (IPC) (IPC).
(2) background technology:
At present, the technology about the ruler group existing and that once had was all done very fruitful effort to a kind of needs of multipurpose ruler, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China on the 15th September in 2004 by Feng Shaoming, Granted publication is that CN2640765Y China Patent No. (ZL) is: ZL03206431.4 number utility model patent title is the utility model patent of " novel lattice chi ", the technical scheme that is adopted, technical elements in the ruler group is a routine of great value invention, and it has solved the technical matters that can accurately measure straight line effectively.But still have some deficits, it also is difficult to solve measures curve, accurately the technical matters of measuring.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of multipurpose ruler.Measure curve to solve, accurately the technical matters of measuring.
The new technical scheme that above-mentioned technical matters to be solved in the utility model adopted is: a kind of multipurpose ruler of the present utility model mainly is made of active wheel, major axis, pinion wheel, prototype gear, minor axis, gear wheel, rack ruler, reading, scale.
In shape, structure and combination thereof, the total essential features of a kind of multipurpose ruler of the present utility model and immediate prior art is: the back side of reading paste be installed in rack ruler above, the top stickup of rack ruler is installed in the back side of scale, be combined into the fixed sturcture of tooth bar shape, function has been the effect of measuring.In shape, structure and combination thereof, a kind of multipurpose ruler of the present utility model technical characterictic different with immediate prior art is: the lower end of active wheel is connected the center, upper end of pinion wheel with major axis, the periphery engagement of pinion wheel is installed in the periphery of gear wheel, be combined into the unitized construction of three cylindrical shapes, function has been the effect of measuring curve.Be installed in the lower end of prototype gear in the middle of the gear wheel with minor axis, the periphery engagement of prototype gear is installed on the tooth of rack ruler, is combined into the rotational structure of the cylindrical shape of band projection, and function has been by kinematic train data to be acted on accurately.So just reached the measurement curve of a kind of multipurpose ruler of the present utility model, accurately the purpose of measuring.
The beneficial effect of a kind of multipurpose ruler of utility model is that the utility model is to solve to measure curve, and accurately the technical scheme of measuring that technical matters adopted has been compared two place's advantage and improvement with existing with the technology about the ruler group that once had:
First, because the lower end of having designed active wheel in the technical scheme of a kind of multipurpose ruler of the present utility model is connected the center, upper end of pinion wheel with major axis, the periphery engagement of pinion wheel is installed in the periphery of gear wheel, be combined into the unitized construction of three cylindrical shapes, so the technical matters of curve is measured in easier solution.
Second, because the middle upper end of having designed gear wheel in the technical scheme of a kind of multipurpose ruler of the present utility model is installed in the lower end of prototype gear with minor axis, the periphery engagement of prototype gear is installed on the tooth of rack ruler, be combined into the rotational structure of the cylindrical shape of band projection, thus easier solution by kinematic train with data accurate technique problem.
(4) description of drawings:
Accompanying drawing provides the structural representation of a kind of multipurpose ruler of the present utility model:
Fig. 1: the one-piece construction synoptic diagram that is a kind of multipurpose ruler of the present utility model;
The label declaration at each position in the synoptic diagram:
1 active wheel, 2 major axis, 3 pinion wheels, 4 prototype gears, 5 minor axises
6 gear wheels, 7 rack rulers, 8 readings, 9 scales
(5) embodiment:
Below in conjunction with accompanying drawing, a kind of multipurpose ruler of the present utility model is measured curve for realizing solving, the optimal way of the technical scheme that the accurate technical matters of measuring is taked is described further:
Its static structure: see also accompanying drawing: as shown in the figure, a kind of multipurpose ruler of the present utility model mainly is made of active wheel 1, major axis 2, pinion wheel 3, prototype gear 4, minor axis 5, gear wheel 6, rack ruler 7, reading 8, scale 9.Its critical part major axis 2, pinion wheel 3, minor axis 5, gear wheel 6, reading 8 are selected for use by market.Its active wheel 1 is a cylindrical shape, is material with plastics, through the thermoforming processing and manufacturing.Its prototype gear 4 is gear shapes, is material with plastics, through the thermoforming processing and manufacturing.Its rack ruler 7 is tooth bar shapes, is material with plastics, through the thermoforming processing and manufacturing.
In shape, structure and combination thereof, the total essential features of a kind of multipurpose ruler of the present utility model and immediate prior art is: the back side of reading 8 paste be installed in rack ruler 7 above, the top stickup of rack ruler 7 is installed in the back side of scale 9, be combined into the fixed sturcture of tooth bar shape, function has been the effect of measuring.In shape, structure and combination thereof, a kind of multipurpose ruler of the present utility model technical characterictic different with immediate prior art is: the lower end of active wheel 1 is connected the center, upper end of pinion wheel 3 with major axis 2, the periphery engagement of pinion wheel 3 is installed in the periphery of gear wheel 6, be combined into the unitized construction of three cylindrical shapes, function has been the effect of measuring curve.Be installed in the lower end of prototype gear 4 in the middle of the gear wheel 6 with minor axis 5, the periphery engagement of prototype gear 4 is installed on the tooth of rack ruler 7, is combined into the rotational structure of the cylindrical shape of band projection, and function has been by kinematic train data to be acted on accurately.
Below by using method, further set forth a kind of multipurpose ruler dynamic structure relation of the present utility model: in use, when needs are accurately measured curve, according to mechanical principle, at first the periphery of active wheel 1 is walked along curve, then by length is amplified in gear drive, reading 8 on chi then again, thus finish the task of accurate measurement curve.
In use, in the time of needs common survey straight line,, at first pick up chi, aim at straight line then according to mechanical principle, reading 8 then again, thus finish the task of common survey straight line.So just realized the measurement curve of a kind of multipurpose ruler of the present utility model, accurately the technical scheme of the technical matters of measuring.
Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of student appliance factory, take small lot batch production,, so just can realize the practical value and the economic worth of a kind of multipurpose ruler of the present utility model better with the demand of supply educational circles.
