Embodiment
As shown in Figure 2, this casing angle locater that is used for installation LED arc screen comprises the first rocking arm 1 and the second rocking arm 2, positioning end 3 at the first rocking arm 1 and the second rocking arm 2 is respectively arranged with the first locating surface 5 and the second locating surface 6, the first rocking arm 1 be connected rocking arm 2 and be connected with axis hole by the rotating shaft that is arranged on the joint face 4, and centered by rotating shaft, relatively rotate.Also be respectively arranged with index plate 7 and pointer 8 on link 4, when the first locating surface 5 and the second locating surface 6 were in the same plane, pointer 8 just pointed to the null position on the index plate 7, showed that the angle between the first locating surface 5 and the second locating surface 6 is 0 degree.
Extremely shown in Figure 4 such as Fig. 2, during use, respectively the first locating surface 5 and the second locating surface 6 are adjacent to the bottom surface of adjacent two casings 14, numerical value from index plate 7 reading pointers 8 indications, this numerical value is the angle between the first locating surface 5 and the second locating surface 6, the angle between the bottom surface of two casings 14 namely, because casing 14 is the rectangular parallelepiped of rule, and be to be fixedly connected with quarter bend 13 by the bottom surface, so the angle numerical value that reads from index plate 7 is the angle between the stationary plane of casing 14, also is the numerical value of the angle R between the LED display 15.The numerical value of contrast angle R and the angle value of designing requirement, whether the setting angle that can judge casing 14 is correct, if setting angle has deviation, change the setting angle of casing 14 by adjusting modes such as space between casing 14 and the quarter bend 13, until angle R is consistent with design angle.Rear being fixed by web joint 16 of adjusting to the right place gets final product.
As shown in Figures 2 and 3, in order to prevent when the install and adjust casing 14, the variation that meets accident of the angle between the first rocking arm 1 and the second rocking arm 2, cause error in reading, cause erroneous judgement, in rotating shaft locking device 9 is set, locking device 9 cooperates with rotating shaft by screw thread.Locking device 9 can be the modes such as nut, screw, after the first locating surface 5 and the second locating surface 6 are adjacent to respectively the bottom surface of casing 14 of both sides, by locking device 9 relative position between the first rocking arm 1 and the second rocking arm 2 is fixed, reading pointer 8 indicated numerical value on index plate 7 again, operating personnel do not discover with regard to having avoided unexpected variation of angle between two rocking arms like this, have finally guaranteed the accuracy of the angle R between the LED display 15.And when casing 14 is adjusted, can be first according to designing requirement, by the angle between pointer 8 and index plate 7 adjustment and definite the first rocking arm 1 and the second rocking arm 2, namely determine the position of the first locating surface 5 and the second locating surface 6, adjust again two side box bodies 14, the bottom surface of casing 14 is overlapped with locating surface, and the setting angle of casing 14 namely reaches designing requirement.
Another better mode is, such as Fig. 2 and shown in Figure 4, at the first rocking arm 1 or the second rocking arm 2 through hole 12 is set, use screw 17 that one of them rocking arm is fixed on the corresponding casing 14, this angle locater has just obtained support like this, no matter be when taking measurement of an angle, or when after determining angle, adjusting casing 14, can be more convenient, rotate more quietly the another one rocking arm, and then measure more accurately and adjust, alleviate operating personnel's burden, avoided the bottom surface of locating surface and casing 14 because the tight and angle R that causes of reclining inaccurate.
As shown in Figure 2, in order to make the first rocking arm 1 and the second rocking arm 2 more steady when doing relative motion, increase the service life simultaneously, positioning end 3 at the first rocking arm 1 is provided with trip bolt 10, be provided with the pilot hole 11 corresponding with trip bolt 10 at the positioning end 3 of the second rocking arm 2, pilot hole 11 is arc.When the angle between adjustment the first rocking arm 1 and the second rocking arm 2, trip bolt 10 is in pilot hole 11 interior slips, spacing effect has been played in pilot hole 11 and trip bolt 10 cooperations, avoids rocking arm crooked in the situation of excessive and improper use of exerting oneself, and affects the accuracy of angle orientation.After adjusting to assigned address, use simultaneously locking device 9 and trip bolt 10 lockings, guarantee that jointly the relative position between the first rocking arm 1 and the second rocking arm 2 can not change, further guaranteed the accuracy of measurement and orientation angle.Situation when trip bolt 10 and pilot hole 11 can use according to reality is set to one group or many groups.
