11 scale area; 21 needle section;
22 Aculeatas; 23 balance weight body;
3 rotating shafts; 111 normal regions;
112 caution zones; 4 fabricated sections.
Embodiment
Be elaborated below in conjunction with the embodiment of accompanying drawing to the utility model.Should be understood that embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
In the utility model, not do under the situation of opposite explanation, the noun of locality of use typically refers to the orientation of angle display under the normal mounting state, the for example orientation under state as shown in Figure 1 like " upper and lower ".
As shown in Figure 1; A kind of embodiment according to the utility model provides a kind of angle display; This angle display comprises dial plate 1 and pointer 2, has scale area 11 on the said dial plate 1, and said pointer 2 comprises the needle section 21 of pointing to said scale area 11 and the Aculeata 22 that is arranged on the said dial plate 1 free to rotately; Wherein, said Aculeata 22 is provided with balance weight body 23.
Pass through technique scheme; Because the Aculeata 22 of pointer 2 is provided with balance weight body 23, therefore under the effect of balance weight body 23, the needle section 21 of pointer 2 is come the scale in the indicating graduation district 11 towards the top all the time; The visual custom that meets the staff; Therefore have and show differentiability preferably, the staff can discern rotational angle fast, is not prone to misread phenomenon.
Said pointer 2 can adopt various suitable modes to be arranged on the dial plate 1 free to rotately; As a kind of concrete embodiment; Said angle display also comprises the rotating shaft 3 that is fixed on the said dial plate 1, and said Aculeata 22 is arranged in the said rotating shaft 3 free to rotately.Preferably, be provided with axle sleeve between said Aculeata 22 and the said rotating shaft 3, thereby said pointer 2 can rotate freelyr with respect to dial plate 1.Said axle sleeve also can be by replacements such as bearings.
The scope that is provided with of the scale area 11 on the said dial plate 1 is confirmed according to the applied field of angle display is incompatible.For example, when angle display was installed on the lifting beam of crane, because the luffing angle of lifting beam is usually at 0 °-80 °, so the meter full scale of scale area 11 also correspondingly was 0 °-80 °.Scale area 11 can confirm then that in the position on the dial plate 1 for example as shown in Figure 1, under original state, this scale area 11 is positioned at the position of the upper left corner (i.e. second quadrant) according to the concrete installation site of angle display on lever arm (for example lifting beam).
