[0021] As Figures 1 to 2 shown, a preferred embodiment of the present utility model provides a hovering lamp, which includes a lamp socket 1, a lamp head 2, a guide rail 3, a slider 4, a pulley 5 and a spring 6. The guide rail 3 is fixed on the lamp socket 1 and extends vertically. The slider 4 is slidably connected to the guide rail 3 up and down. A damping block is provided on the slider 4 to generate static friction with the guide rail 3 to increase the moving resistance of the slider 4. The lamp head 2 is fixedly connected to the slider 4. The pulley 5 is provided on the lamp socket 1 and above the guide rail 3. The spring 6 is provided on the lamp socket 1 and below the guide rail 3. A wire rope 7 is connected to the spring 6. One end of the wire rope 7 is fixedly connected to the spring 6, and the other end of the wire rope 7 bypasses the pulley 5 and is fixedly connected to the lamp head 2. The static friction force between the guide rail 3 and the damping block is greater than or equal to the absolute value of the gravity of the lamp head 2 and the pulling force of the spring 6.
[0022] When the user moves the lamp head 2, the damping block can control the falling speed of the lamp head 2, thus preventing the lamp head 2 from falling rapidly or stopping suddenly; when the user moves the lamp head 2 to the desired position and releases it, the damping block can help the lamp head 2 to stop steadily at this position, thus realizing the automatic hovering effect of the lamp head 2; and since the static friction force between the guide rail 3 and the damping block is greater than or equal to the absolute value of the gravity of the lamp head 2 and the pulling force of the spring 6, no matter where the lamp head 2 is located, the static friction force can hinder the movement of the lamp head 2, thus ensuring the hovering of the lamp head 2; thus, through the cooperation between the guide rail 3, the slider 4, the damping block, the pulley 5, the spring 6 and the steel wire rope 7, the lifting and hovering of the lamp head 2 can be realized. At the same time, through the cooperation between the guide rail 3 and the slider 4, the jamming phenomenon during the lifting and lowering adjustment of the lamp head 2 can be avoided, which is convenient for adjustment; by adopting the utility model, the automatic hovering effect of the lamp head 2 can be realized, the adjustment process is stable, the structure is simple, and the operation is convenient.
[0023] Exemplarily, a first connection block 8 for connecting with the lamp head 2 is arranged on the slider 4, a sliding groove 9 matched with the first connection block 8 is arranged on the lamp base 1, and the sliding groove 9 is arranged opposite to the guide rail 3.
[0024] Exemplarily, a second connection block 10 is arranged on the lamp head 2, the second connection block 10 is connected with the first connection block 8 through a connecting rod 11, one end of the connecting rod 11 is rotatably connected with the first connection block 8, the other end of the connecting rod 11 is rotatably connected with the second connection block 10, and the rotation axis between the connecting rod 11 and the first connection block 8 is parallel to the rotation axis between the connecting rod 11 and the second connection block 10; thus, when in use, the angle of the lamp head 2 relative to the lamp base 1 can also be adjusted, so as to better adapt to different use environments, and the practicability is strong.
[0025] Exemplarily, rubber friction rings are arranged between the connecting rod 11 and the first connection block 8 and between the connecting rod 11 and the second connection block 10. Through the arrangement of the rubber friction rings, a large friction force can be generated between the connecting rod 11 and the first connection block 8 or between the connecting rod 11 and the second connection block 10 in the rotating state, so that the connecting rod 11 and the lamp head 2 can only rotate under the action of an external force and will not rotate due to their own weight, so that the lamp head 2 can be in a stable state when rotating to any state, which is convenient for use.
[0026] Exemplarily, the lamp holder 1 includes a vertical rod 12 and a base 13. An accommodation cavity 14 is provided inside the vertical rod 12. The guide rail 3, the slider 4, the pulley 5 and the spring 6 are all arranged inside the accommodation cavity 14, that is, the guide rail 3, the slider 4, the pulley 5 and the spring 6 can be hidden inside the accommodation cavity 14 to avoid the leakage of parts, thus ensuring the neat and generous appearance of the whole lamp and strong aesthetics. The base 13 is fixed at the lower end of the vertical rod 12. The base 13 is arranged in a rectangle, which can ensure the contact area with the desktop, etc., so as to avoid the lamp from tipping over during the process of adjusting the lamp up and down.
[0027] Exemplarily, a rotary switch 15 for controlling the opening and closing of the lamp head 2 and the brightness of the lamp head 2 is provided on the vertical rod 12, which is convenient for adjustment.
