Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing embodiment of the present utility model is explained in detail.Yet, persons of ordinary skill in the art may appreciate that in embodiment of the present utility model, in order to make the reader understand the application better many ins and outs have been proposed.But, even without these ins and outs with based on many variations and the modification of following embodiment, also can realize each claim of the application technical scheme required for protection.
A preferred embodiments of the present utility model relates to a kind of protractor of angle adjustable, as shown in Figure 1, comprises housing 3, the spirit-leveling instrument 9 of angle adjustable, horizontal spirit-leveling instrument 6.
Wherein, the spirit-leveling instrument 9 of angle adjustable comprises: vertical level instrument 2, top rotary table 1 and lower rotary table 4; The disk cover of top rotary table 1 is provided with angle index mark 7; Housing 3 is provided with the graduation indication mark.
Specifically, the rotating disk chamber of the rotating disk chamber of top rotary table 1 and lower rotary table 4 is positioned at housing 3; The disk cover of the disk cover of top rotary table 1 and lower rotary table 4 is surperficial concordant with housing 3, as shown in Figures 2 and 3; Top rotary table 1 and lower rotary table 4 are in the same place by fastened by screw; Vertical level instrument 2 is positioned at the rotating disk chamber 12 of top rotary table.Be provided with two symmetrically arranged the first projections 13 in the rotating disk chamber of top rotary table 1, be used for fixed vertical spirit-leveling instrument 2; Vertical level instrument 2 is fixed in the first projection 13 away from a side of disk cover.
Horizontal spirit-leveling instrument 6 is positioned at housing 3, is fixed on the accessory 51, and accessory 51 is fixed on the housing 3, as shown in Figure 3.Housing 3 is provided with opening at upper surface, by the horizontal spirit-leveling instrument 6 of this opening Observable, as shown in Figure 4.
The protractor use-pattern of present embodiment is as follows:
When needs fitting machine motor-car radar meter, such as MPU-R(Micro Pu Radar-Upside is installed) during the motor vehicle radar meter, the at first top rotary table 1 of rotary protractor or lower rotary table 4, the spirit-leveling instrument of angle adjustable is adjusted to the angle of the vertical direction that needs installation, it is the angle of the needs of scale cue mark 8 orientation angle scale marks 7 vertical direction of installing, such as, if needing the angle of the vertical direction of installation is 25 degree, the then top rotary table 1 of rotary protractor or lower rotary table 4 are until 25 degree of graduation indication mark 8 orientation angle scale marks 7; Then protractor is placed the top of radar, then regulate the bolt that is used for installing radar.Owing to by the upper surface open of housing 3, in the middle of whether the bubble in the horizontal spirit-leveling instrument 6 of Observable is positioned at, therefore by the adjusting to bolt, when the bubble in observing horizontal spirit-leveling instrument 6 is positioned at the centre position, illustrate that this radar is horizontal; And owing to pass through top rotary table 1 or the lower rotary table 4 of rotary protractor, the spirit-leveling instrument of angle adjustable has been adjusted to the angle of the vertical direction that needs installation, therefore by the adjusting to bolt, so that the bubble in the vertical level instrument 2 when being positioned at the centre position, illustrate this radar in vertical direction adjusted to required angle.That is to say that by regulating the bolt that is used for installing radar, so that the bubble of the horizontal spirit-leveling instrument of protractor and vertical level instrument all is positioned at the centre position, horizontal direction calibration and the vertical direction of so far namely having finished the radar installation are installed to predetermined angle.
It is worth mentioning that the lower surface of protractor housing need to be arranged to irregular surface according to the measurement datum at radar top, making protractor is not can finish measurement in the situation on plane at measurement datum yet.
Compared with prior art, present embodiment makes protractor realize the calibration of horizontal direction when fitting machine motor-car radar meter by the usage level spirit-leveling instrument; By the spirit-leveling instrument of angle adjustable, make protractor when fitting machine motor-car radar meter, can measure the angle of vertical direction; Further, the lower surface of housing is arranged to irregular surface according to the measurement datum of radar, making protractor is not can finish measurement in the situation on plane at measurement datum yet.In addition, because that the spirit-leveling instrument of angle adjustable can be adjusted to before installing is arbitrarily angled, therefore embodiment of the present utility model can be realized the measurement of angle adjustable, no longer is that fixed angle is measured.
Persons of ordinary skill in the art may appreciate that above-mentioned embodiment is to realize specific embodiment of the utility model, and in actual applications, can do various changes to it in the form and details, and do not depart from spirit and scope of the present utility model.
