[specific embodiment]
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.
Embodiment 1: described street lamp angle demodulator, comprise lamp stand anchor tip 1, lamp holder fixed muffle 2, angle demodulator 3, it is characterized in that, described angle demodulator 3 comprises an outside support 4 that is connected with the lamp stand anchor tip, an adjusting connector 5 that is connected with the lamp holder fixed muffle, described adjusting connector 5 rear ends extend into the intermediate space part of outside support 4, described outside support 4 and adjusting connector 5 are run through by the couple axle 6 that two ends stretch out in outside the outside support, combine, end at couple axle 6 reaches a fixed internal gear sheet 7 outside the outside support 4, tapping thread on the axle body of the other end of couple axle 6, support 4 outer surfaces externally, the position that corresponding internal gear is 7 is fixed with a circle external tooth wheel rim 8, there is a locking nut 9 at 6 tapping thread places at couple axle, when described locking nut 9 was in locked extreme position, described internal gear sheet 7 was interlocked with external tooth wheel rim 8.
Socket between described couple axle 6 one section of centre and the adjusting connector 5, socket part is the multiaspect axon, does not promptly have the rotation surplus between the two.Hole on described couple axle 6 two and the outside support 4 is an interference fit, can freely rotate between the two.
The mode that described external tooth wheel rim 8 can weld or screw is fixing is fixed in outside support 4 surfaces, and the hole maintenance on the outside support 4 that external tooth wheel rim and couple axle pass is coaxial.
Described internal gear sheet 7 is fixed in couple axle 6 ends, can adopt to be welded on the couple axle 6, or adopt the interference fits cover to receive on the couple axle 6 or the polyhedron socket.There is not the activity surplus between internal gear sheet 7 and the couple axle 6, cannot freely rotates.
On lamp stand anchor tip 1 and lamp holder fixed muffle 2, fixed screw 12 is arranged all, be used for angle adjuster is connected and fixed with lamp stand and lamp holder.
Concrete operations work engineering is as follows: it is good that the lamp stand anchor tip is fixedlyed connected with lamp stand, cap part is installed on the lamp holder fixed muffle again, so angle demodulator is installed on the street lamp, connect and played lamp stand and cap part, when needing adjusting angle, earlier locking nut is unscrewed, twitch couple axle, internal gear sheet and external tooth wheel rim break away from interlock, so can freely rotate couple axle, drive is cemented in the adjusting connector on the couple axle interlude, is installed on the angle of regulating the lamp holder on the connector like this and just realizes having adjusted.The gear sheet that has rotated certain angle is pushed the position of getting back to external tooth wheel rim originally again along axis direction after having rotated, gear interlock, chucking.So the angle of having rotated has been fixed, at last as long as just finished whole angular adjustment process with the locked couple axle of locking nut.
