Device for controlling lifting of lighting lamp

A device for controlling a lighting lamp to ascend and descend is characterized by comprising a transverse rod (1), a lifting lug (2), a pull rope (3), a pulley (4), a sliding roller (5) and a connecting rod (6). The four connecting rods (6) are welded between the two cross rods (1), and the distance between the connecting rods (6) on the outer side and the connecting rods (6) on the adjacent inner side is 300 mm. And the two lifting lugs (2) are respectively welded at the middle positions of the two inner side connecting rods (6). And the two pulleys (4) are distributed on the two sides of the sliding roller (5). And one ends of the two pull ropes (3) are fixed with the lifting lugs (2), and the other ends penetrate through the pulleys (4) and the sliding rollers (5). The illumination lamp has the advantages of being easy to assemble, convenient to operate, simple and practical, avoiding use of a lamp holder and a crane, saving manpower and material resources, meanwhile being capable of adjusting the height
