Abstract
The utility model relates to a universal-purpose angle ruler, which is mainly composed of a main scale, a pressing scale, a scale, a backing board, pressing scale bolts, a central shaft and clamping nuts. The main scale, the pressing scale and the backing pad are connected as a whole by the central shaft and the clamping nuts, and the scale is fixed between the pressing scale and the main scale by the pressing scale bolts which are spirally arranged on the pressing scale to make the aim of drawing any angle realized. The utility model has the advantages of simple structure, convenient operation and reliable performance, and can be suitable for drawing any angle and measuring depth and the center of a circumference, having an application to engineers and mapping staff and machinists to use.
Description
The utility model relates to a kind of measurer, and refering in particular to is a kind of omnipotent protractor.
Present commercially available various bevel protractors, Arbitray angle divider, because of its complex structure, annex is many, cost is high, usable range is little, brings inconvenience for manufacturing and use.
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple in structure, reasonable in design, omnipotent protractor easy to use.
The utility model is to adopt following proposal to realize: on a set square, be provided with one 360 ° of five equilibrium gardens, center in the garden, by screw one pressing plate which is provided with scale is installed, on pressing plate, be provided with two nose bar screws, between set square and nose bar, be installed with a rule, and by nose bar screw location.
Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is the utility model front view.
Accompanying drawing 2 is the utility model A-A cut-open view.
Referring to accompanying drawing 1,2, the utility model is made up of central shaft (1), main scale (2), backing plate (3), clamp nut (4), nose bar (5), nose bar screw (6), rule (10).Described main scale (2) is a triangular plate, which is provided with the garden week (7) of one or 360 ° five equilibrium, central shaft (1) is installed in the garden week center pit, backing plate (3) is bonded as one with nose bar (5), be installed on the central shaft (1) by clamp nut (4), nose bar (5) is provided with scale (8), and nose bar screw (6) spinning is on nose bar (5), and rule (10) is installed between nose bar (5) and the main scale (2) by nose bar screw (6).
When using the utility model, only need a limit with main scale (2) as the one side that will draw angle, then, nose bar (5) and rule (10) are rotated around central shaft (1), make the scale (8) on the nose bar (5) aim at the pairing scale of the number of degrees that 360 ° of five equilibrium garden Zhou Shangxu draw the angle, a line draws along the limit of rule (10).
The utlity model has the advantages such as simple in structure, easy to operate, dependable performance, it is arbitrarily angled not only to be suitable for picture, and can be used for fathoming, and measures the central point in garden week. Being suitable for engineers and technicians and mapping worker and mechanic uses.
