In the figure: 1-a lamp holder; 2-a lamp barrel; 3-rotating the sleeve; 4-a collar; 5-a sleeve; 6-ring plate; 7-a compression bar; 8-a guide rod; 9-bending part.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
Examples
As shown in fig. 1-2, a down lamp comprises a lamp holder 1 and a lamp barrel 2, a rotary sleeve 3 is rotatably sleeved at the joint of the lamp holder 1 and the lamp barrel 2 in a fixed-axis manner, a sleeve ring 4 is fixed at the upper port of the rotary sleeve 3, a sleeve 5 with external threads is coaxially fixed on the sleeve ring 4 near the edge of an inner ring, the sleeve 5 is coaxially sleeved in a ring groove formed on the side wall of the lamp barrel 2, the sleeve 5 slides relative to the lamp barrel 2, a ring plate 6 is in threaded connection with the sleeve 5, a plurality of pressure levers 7 are hinged at the edge of an outer ring of the ring plate 6 through a pin shaft and a coil spring, the plurality of pressure levers 7 are uniformly distributed on the ring plate 6 along the outer ring direction of the ring plate 6, the pressure levers 7 keep a vertically downward state under the action of the coil spring, a guide lever 8 corresponding to the pressure lever 7 is fixed on the upper surface of the ring groove of the lamp barrel 2, the length of the pressure lever 7 is not greater than that of the guide lever 8, the guide lever 8 slides through the ring plate 6, and a bending part 9 is fixed at the lower end of the guide lever 8, the bend 9 is arc-shaped and the lowest end of the bend runs from the lower end of the guide rod 8 towards the outer side of the swivel housing 3.
In this embodiment, the external diameter of the rotary sleeve 3 is greater than the internal diameter of the hole formed in the ceiling, and the diameters of the lantern ring 4, the annular plate 6 and the lamp tube 2 are all less than the internal diameter of the hole formed in the ceiling, so that the down lamp is pressed tightly on the ceiling by the pressing rod 7, and the installation stability is maintained.
