Abstract

The utility model discloses a simplified measurer which comprises a battery box fixing plate, a battery box, a protractor, a pointer, a laser pen, a laser pen fixing frame, a power switch, a circuit board, screws, a gasket, a button battery and a light emitting diode. Four double-color boards are glued together to form the battery box which is glued at the tail end of an organic glass plate; the double-color boards are cut to make the pointer; two holes are respectively perforated at the upper part and the lower part of the middle of the bottom of the protractor which is glued with one side of the organic glass plate; the peeled cartridge part of the laser pen is adhibited with the double-color boards; and the double-color boards are fixed at the round holes of the protractor through the screws. The protractor is based on the characteristic of low energy consumption of the light emitting diode and the rectilinear propagation principle of light, through the rectilinear radiation of the light, an angle ruler can measure the angle or draw the desired angle at a place within the reach of the light, and the measurement process is simple, convenient and quick.

Description

A kind of ordinary surveying device

Technical field:

The utility model relates to the ordinary surveying device of the straightline propagation principle design of the light emitting diode low energy consumption of a kind of measuring appliance, particularly a kind of utilization and light.

Background technology

Common protractor can only be measured the small size object, because measured angle line segment is short, can't measure the angle of large tracts of land or big object.

The utility model is for solving the not problem of the big object of energy measurement or large-area angle of common protractor, thereby provides a kind of ordinary surveying device to make measurement simple and convenient more with exactlying. can also doublely do the horizon rule practicality in addition.

The technical solution of the utility model is: a kind of ordinary surveying device, comprise: battery case fixed head, battery case, protractor, pointer, laser pen, laser pen fixed mount, power switch, wiring board, screw, pad, button battery, light emitting diode, it is characterized in that: adopt four blocks of double-colored plates to be glued together and make battery case, battery case sticks at the poly (methyl methacrylate) plate end; Cut double-colored plate and do pointer; Two holes are made a call at the place respectively up and down in the middle of the angulation bottom, and a side of protractor and poly (methyl methacrylate) plate is glued; The core section and the double-colored plate of laser pen peeling is bonding, with the circular hole place of screw with double-colored plate fixed amount hornwork; The positive pole of battery links to each other by switch and light emitting diode are anodal, and the negative pole of battery links to each other with diode cathode.

The utility model has the advantages that: utilize the straightline propagation principle of light emitting diode low energy consumption and light, made an ordinary surveying device. bevel protractor in the place that light can arrive, just can be measured its angle or the required angle of drawing by the straight line irradiation of light.And measure simple, convenient.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is the schematic diagram of the utility model ordinary surveying device;

Fig. 2 is a side view of the present utility model;

Fig. 3 is a circuit diagram of the present utility model.

Shown in the accompanying drawing: battery case fixed head 1, battery case 2, protractor 3, pointer 4, laser pen 5, laser pen fixed mount 6, power switch 7, wiring board 8, screw 9, pad 10, button battery 11, light emitting diode 12.

The specific embodiment

The making of ordinary surveying device, at first, intercept long 1.7cm, two blocks of double-colored plates of wide 1.3cm, at intercepting 1.6cm, two blocks of double-colored plates of wide 1.4cm, be glued together the formation battery case. intercept long 9cm, the poly (methyl methacrylate) plate of wide 1.8cm sticks at the poly (methyl methacrylate) plate end with battery case, makes a pointer at double-colored plate of intercepting. and two holes are made a call at the place respectively up and down in the middle of the protractor low side, side with protractor and poly (methyl methacrylate) plate is glued earlier, laser pen skinning machine core segment and double-colored plate is bonding, with the circular hole place of screw with double-colored plate fixed amount hornwork. the positive pole of battery links to each other with diode cathode by switch, and the negative pole of battery links to each other with diode cathode, it is luminous to open the switch laser pen, this is just can normal practical measuring appliance, because the straightline propagation characteristic of light, the place that light can shine all is the range ability of this measuring appliance.

In conjunction with the accompanying drawings, measuring appliance is placed on horizontal level, select a datum mark, (protractor 0 is spent to 180 degree line center alignment fiducials points the measuring appliance central point again, open computer switch 7 then, adjust laser pen 5 luminous points, be that illumination is put formation A point at institute's location of survey object, this is to note the position angle X degree of pointer 4 on dial (protractor 3). rotary indicator 4, and luminous point is impinged upon form the B point on another position of the object of surveying, at this moment note the position Y degree of pointer 4 on dial, 2 angles to datum mark of the object of surveying are the angle that pointer 4 rotates on dial, be the X degree to the angle between the Y degree, close switch 7, measure to finish.

Can also make horizon rule in addition uses, such as on the ground of building a house, four mark posts are holded up at four angles respectively on foundations ground, and measuring appliance is placed on any horizontal level in foundations ground, open switch then, adjust the laser nib on the pointer, luminous point being impinged upon respectively form four points on four mark posts and carry out record, is on same level at four points, and promptly the level of premises base has been copied, close switch, measure and finish.

Claims

1. ordinary surveying device, comprise: battery case fixed head, battery case, protractor, pointer, laser pen, laser pen fixed mount, power switch, wiring board, screw, pad, button battery, light emitting diode, it is characterized in that: adopt four blocks of double-colored plates to be glued together and make battery case, battery case sticks at the poly (methyl methacrylate) plate end; Cut double-colored plate and do pointer; Two holes are made a call at the place respectively up and down in the middle of the angulation bottom, and a side of protractor and poly (methyl methacrylate) plate is glued; The core section and the double-colored plate of laser pen peeling is bonding, with the circular hole place of screw with double-colored plate fixed amount hornwork; The positive pole of battery links to each other by switch and light emitting diode are anodal, and the negative pole of battery links to each other with diode cathode.
