The spring constant of the second spring 32 is much smaller than that of the third spring 33 in the present invention; when the second stopper 31 is retracted inward along the inner wall of the telescopic jacket 30, the second stopper 31 compresses the second spring 32, and the compressed second spring 32 does not compress the third spring 33 through the telescopic jacket 30 to cause the telescopic jacket 30 to move.
According to the invention, the elasticity generated by the volute spiral spring 19 is smaller than the elasticity generated by the third spring 33, so that when two swing arms 24 which are not fixed are adjusted, the situation that the volute spiral spring 19 deforms to cause movement of the telescopic outer sleeve 30 due to the fact that the telescopic outer sleeve 30 pulls the corresponding winding wheel 16 to rotate through the thin steel wire rope 34 when the swing arms 24 swing towards the direction of winding the thin steel wire rope 34 does not occur.
The slack created by the slick line 34 in the present invention does not cause it to fall off the respective winding wheel 16.
The working process of the invention is as follows: in the initial state, the three swing arm mechanisms 22 are distributed at 120 degrees, the third spring 33 is in a pre-compressed state, the spiral spring 19 is in a compressed energy storage state under the action of the steel wire rope, and at the moment, the first fixture block 15 and the corresponding second fixture block 18 form an angle of 180 degrees. The third spring 33 is in a pre-compressed state, and the two first limit blocks 13 arranged on the unlocking shaft 12 are respectively positioned in the two limit grooves 11 on the inner wall of the limit sleeve 8; the second stopper 31 is located outside the guide rail 27, the second spring 32 is in a natural state, and the thin steel wire rope 34 is in a natural straightening state.
When three fixed orificess that the required mounted position of LED ceiling lamp was beaten at indoor roof is not circumference evenly distributed, earlier with a bolt and one of them fixed orifices cooperation and be fixed in the roof to a swing arm 24 in the LED ceiling lamp, make the center of bearing plectane 4 and the required mounted position's of LED ceiling lamp center department coincide, then in proper order around 12 central axes swings remaining two not fixed swing arms 24 of unblock axle, make locating hole 26 on remaining two swing arms 24 respectively with remaining two fixed orificess on the roof relative, reuse bolt is fixed remaining two swing arms 24 respectively, lighting fixture mechanism 1 installation is ended.
In the process of carrying out adaptive swing operation on two swing arms 24 which are not fixed and fixing the swing arms, as the two first limit blocks 13 arranged on the unlocking shaft 12 are respectively positioned in the two limit grooves 11 on the inner wall of the limit sleeve 8, the unlocking shaft 12 does not rotate; since the winding wheel 16 engaged with the fixed swing arm 24 is stationary relative to the unlocking shaft 12, the winding wheel 16 engaged with the fixed swing arm 24 does not rotate relative to the unlocking shaft 12, and therefore, when the swing arm 24 of any one of the remaining swing arm mechanisms 22 is swung, the thin wire rope 34 connected to the corresponding winding wheel 16 of the remaining two swing arm mechanisms 22 is tightened or loosened regardless of the swing in that direction; if the thin steel wire rope 34 connected with the corresponding winding wheel 16 in the swing arm mechanism 22 is tightened, the third spring 33 is pre-compressed because the elasticity generated by the spiral spring 19 is smaller than the elasticity generated by the third spring 33, so that the third spring 33 does not deform, the non-deformed third spring 33 still pulls the thin steel wire rope 34 through the telescopic outer sleeve 30 under the condition of no deformation, the thin steel wire rope 34 enables the winding wheel 16 corresponding to the thin steel wire rope to drive the spiral spring 19 in the thin steel wire rope to deform and store energy, and the included angle between the first fixture block 15 and the second fixture block 18 is reduced; when the swing arm mechanism 22 swings to the target fixing hole, the third spring 33 still does not deform, and the second limiting block 31 is still at the initial position outside the guide rail 27 because the telescopic outer sleeve 30 in the swing arm mechanism 22 does not move along the sliding groove 28 in the guide rail 27 at this time; if the thin steel wire rope 34 connected with the corresponding winding wheel 16 in the swing arm mechanism 22 is loosened, the original stored energy can rotate the corresponding winding wheel 16 to the direction of recovering the volute spiral spring 19 to tighten the loosened steel wire rope, and meanwhile, the included angle between the first clamping block and the second clamping block 18 is reduced, so that the loosened steel wire rope is prevented from jumping out of the winding groove of the corresponding winding wheel 16, the third spring 33 cannot deform in the process, and the swing arm mechanism 22 can swing to a target fixing hole without hindrance in the swinging direction; because the third spring 33 is still not deformed, the telescopic outer sleeve 30 in the swing arm mechanism 22 does not move along the sliding groove 28 in the guide rail 27 at this time, and the second limit block 31 is still positioned outside the guide rail 27; the swing arm 24 and the ladder sleeve 6 in the fixed swing arm mechanism 22 do not rotate relatively, so the corresponding thin steel wire rope 34 is not tightened or loosened, the third spring 33 and the corresponding spiral spring 19 in the winding wheel 16 are not deformed, the corresponding telescopic outer sleeve 30 does not move along the sliding groove 28 in the guide rail 27, and the second limit block 31 is still at the initial position outside the guide rail 27; after the two remaining swing arm mechanisms 22 which are swung to the proper positions are fixed by bolts, the whole lamp holder mechanism 1 is fixed at the position where the dome lamp needs to be installed, at the moment, the second limiting blocks 31 in the three swing arm mechanisms 22 are still positioned at the outer sides of the corresponding guide rails 27, and then the lamp body 35 is nested towards the outer sides of the guide rails 27 in the three swing arm mechanisms 22; the upper edge of the inner circular surface of the upper end part of the lamp body 35 acts on the inclined surface of the exposed end of the second limiting block 31 in the three swing arm mechanisms 22, meanwhile, the three second limiting blocks 31 are made to shrink and slide along the inner wall of the corresponding telescopic outer sleeve 30, and the limitation of the upward movement of the lamp body 35 along the arc-shaped end surface of the outer side of the guide rail 27 is gradually removed by the three second limiting blocks 31; since the second spring 32 has a much smaller spring constant than the third spring 33, the second spring 32 located in the telescopic sheath 30 is compressed; when the lamp body 35 goes up over the second stoppers 31 in the three swing arm mechanisms 22, the lower end of the unlocking shaft 12 passes through the yielding hole 36 at the center of the lamp body 35; under the action of the second spring 32, the second stoppers 31 in the three swing arm mechanisms 22 respectively slide outwards along the inner walls of the corresponding telescopic jackets 30 and limit the lamp body 35, and under the limitation of the three second stoppers 31, the lamp body 35 cannot slide along the outer end faces of the three guide rails 27, and the process of completely installing the lamp body mechanism 2 on the lamp holder mechanism 1 is finished.
Then, the four shifting strips 38 positioned at the outer side of the lamp body 35 are shifted by hands, so that the four shifting strips 38 respectively drive the limiting strips 40 to swing into the outer edge of the lamp body 35 around the central axis of the connecting rod 39 through the corresponding connecting rods 39 without hindering the nesting of the lampshade 3 to the lower end of the lamp body 35; then the hand-held lampshade 3 is sleeved on the outer edge of the lower end of the lamp body 35, and the four shifting strips 38 are respectively shifted in sequence by one hand, so that the shifting strips 38 drive the limiting strips 40 to swing towards the lampshade 3 positioned on the outer side through the connecting rod 39, the lampshade 3 is limited, and the lampshade 3 is installed.
