Fig. 1 and 2 respectively show a structural schematic view and an explosion schematic view of the lamp of the present embodiment, and as shown in fig. 1 and 2, the lamp includes a lamp housing main body 1, a telescopic device 2, a rotating device 3 and a swinging device 4 are installed in the lamp housing main body 1, wherein the swinging device 4 is further directly connected with a lamp head 6. The telescopic device 2 is connected to the rotating device 3 and the swinging device 4, and drives the rotating device 3, the swinging device 4 and the lamp head 6 connected with the swinging device 4 to move in the vertical direction.

Specifically, in the present embodiment, the lamp housing body 1 is cylindrical as a whole, the telescopic device 2 in the lamp housing body 1 includes a first motor 21, a first transmission mechanism 22 and a sliding mechanism 23, and both the first motor 21 and the first transmission mechanism 22 are mounted on the sliding mechanism 23. Wherein, the sliding mechanism 23 includes a first lead screw 231 and a second lead screw 232, and the first motor 21 is mounted on the first lead screw 231. The first transmission mechanism 22 is located below the first motor 21, and includes a first belt pulley 221 disposed on the first lead screw 231 and the second lead screw 232, and a first belt 222 is sleeved outside the first belt pulley 221, so as to realize connection between the first belt pulleys 221.

When the first motor 21 starts to operate, the first belt pulley 221 located at the first lead screw 231 starts to rotate, and the first belt 222 is tightened along with the rotation of the first belt pulley 221 located at the first lead screw 231, and generates a friction force, so that the first belt pulley 221 mounted on the second lead screw 232 also rotates, and drives the second lead screw 232 to rotate. In this embodiment, the rotating device 3 is installed below the first transmission mechanism 22 and movably connected to the first lead screw 231 and the second lead screw 232. At the same time, the rotating device 3 is also connected with a swinging device 4 connected with a lamp cap 6. Therefore, when the first motor 21 drives the first lead screw 231 and the second lead screw 232 of the sliding mechanism 23 to rotate through the first transmission mechanism 22, the rotating device 3 and the swinging device 4 connected with the lamp head 6 move in the vertical direction along the first lead screw 231 and the second lead screw 232. Fig. 3 shows a schematic view of a state that the lamp cap 6 of the lamp in this embodiment is extended and retracted in the lamp housing body 1, and referring to fig. 3, under the driving of the extension and retraction device 2, the rotation device 3 and the swing device 4 move along the sliding mechanism 4, so that the lamp cap 6 can be retracted into the lamp housing body 1, and also can be extended out from the inside of the lamp housing body 1, thereby achieving the adjustment of the lamp cap 6 in the vertical direction.

Fig. 4 shows an assembly schematic diagram of the rotating device in the present embodiment, and in conjunction with fig. 1 to 4, the rotating device 3 includes a base plate 31 movably connected to a first lead screw 231 and a second lead screw 232, and a second motor 32 and a second transmission mechanism 33 are mounted on the base plate 31.

Specifically, the second transmission mechanism 33 includes a second pulley 331 and a third pulley 332. Wherein the second pulley 331 is installed at the installation hole 311 provided in the middle of the base plate 31, and the second pulley 331 protrudes toward the direction in which the swing device 4 is located. The third pulley 332 is connected to a lower end of the second motor 32, and is protruded in the same direction as the second pulley 331. The second belt 333 is sleeved outside the second belt pulley 331 and the third belt pulley 332 for connecting the second belt pulley 331 and the third belt pulley 332. In the present embodiment, the mounting hole 311 is located at the center of the substrate 31, and the center axis of the mounting hole 31 is the same as the center axis of the lamp body 1.

In addition, the second pulley 331 is further provided with a fixing portion 334 at an end close to the swing device 4, and accordingly, the swing device 4 includes a fixing plate 411, the fixing plate 411 is provided with a fixing groove 413 corresponding to the fixing portion 334, the fixing groove 413 is recessed in a direction away from the fixing portion 411, and the fixing portion 334 is installed in the fixing groove 413.

When the second motor 32 of the rotating unit 3 operates, similar to the telescopic unit 2, the third pulley 332 connected to the lower end of the second motor 32 starts to rotate, the second belt 333 presses against the second pulley 331 and the third pulley 332, and generates friction, and the second belt 333 drives the second pulley 331 to rotate around the central axis of the lamp housing body 1 in the circumferential direction under the action of the friction. At this time, since the fixing plate 411 of the swinging unit 4 is connected to the fixing portion 334 of the second pulley 331, when the second pulley 331 is driven by the second motor 32 to rotate, the swinging unit 4 rotates along with it, and drives the lamp head 6 connected to the swinging unit 4 to horizontally rotate with the central axis of the lamp housing body 1 as a fixing axis. In this embodiment, the oscillating device 4 and the lamp body 6 can rotate around the central axis of the lamp housing body 1 in a circumferential direction of 0 to 360 degrees.
