As shown in fig. 7, the incomplete gear ring 9 is driven by an independent second motor 27, in actual use, the output end of the second motor 27 is fixedly connected with a driving shaft, the second belt 6 is sleeved outside the driving shaft and the incomplete gear ring 9, at this time, the spiral lifting rod 22 and the sleeve 7 can be driven to rotate by the cooperation of the first motor 3 and the second motor 27, and the accuracy of the cooperation between the spiral lifting plate and the baffle 16 can be improved to a certain extent.
Working principle: the rotating shaft 17 is driven by a motor to rotate, so that the spiral lifting rod 22 is driven to rotate, the lamp body 2 can be driven to move upwards in the lamp post 19 through forward rotation of the spiral lifting rod 22, meanwhile, the incomplete gear ring 9 can be driven to rotate through cooperation of the first transmission shaft 4 and the second belt 6, the sleeve 7 can be driven to rotate through cooperation of the transmission teeth on the incomplete gear ring 9 and the gear 8, the sleeve 7 is in threaded connection with the sleeve 12, the limit bar 11 on the outer side of the sleeve 12 slides in the limit post 10, the sleeve 12 can be prevented from rotating through cooperation of the limit post 10 and the limit bar 11, so that the sleeve 12 can be driven to move along the axis direction of the sleeve 7 when the sleeve 7 rotates, the sleeve 12 can be driven to move downwards when the sleeve 7 rotates, and the first hinging seat 13 on the top end of the sleeve 12 is hinged with the second hinging seat 15 on the outer side of the baffle 16 through 14, so that the baffle 16 can be driven to rotate outwards when the sleeve 12 moves downwards; specifically, when the spiral lifting rod 22 drives the topmost lamp body 2 to move upwards and transits from the first chute 24 on the inner side of the lamp post 19 to the second chute 25 on the inner side of the baffle 16, the spiral lifting rod 22 gradually breaks away from contact with the sliding block 23 on the outer side of the lamp body 2, and the transmission teeth on the outer side of the incomplete gear ring 9 are just meshed with the gear 8 on the same side of the baffle 16 at the moment, so as to drive the sleeve 7 on the side to rotate, as described above, the sleeve 7 can be rotated forward to drive the sleeve 12 to move downwards so as to drive the baffle 16 on the side to rotate outwards, and the sliding block 23 on the topmost lamp body 2 is placed in the second chute 25 on the inner side of the baffle 16 at the moment, so that when the baffle 16 rotates outwards, the lamp body 2 can be driven to synchronously outwards turn over, as shown in fig. 8;
When the baffle 16 drives the lamp body 2 to turn over a certain angle to be almost parallel to the ground, the transmission teeth on the incomplete gear ring 9 are disengaged from the gear 8 on the side, and at the same time, the spiral lifting rod 22 rotates forward to drive the second lamp body 2 from top to bottom to move upwards, similar to the movement condition of the topmost lamp body 2, when the second lamp body 2 moves upwards and moves from the first chute 24 to the inside of the second chute 25, the incomplete gear ring 9 is engaged with the gear 8 under the baffle 16 on the same side at the moment, so that the baffle 16 connected with the second lamp body 2 is driven to rotate outwards, the second lamp body 2 can be driven to turn outwards, and the operation is repeated, so that the four lamp bodies 2 in the lamp body 2 can be turned over to the outer sides of the lamp body 2, and illumination operation is performed through the four lamp bodies 2.
