Detailed Description

The utility model will be further described with reference to the following description and embodiments in conjunction with the accompanying drawings:

as shown in fig. 1 to 4, an eccentric head-swinging lamp structure includes: the lower side of the mounting seat 1 is inwards provided with an arc-shaped concave cavity 2; the eccentric swinging head comprises a connecting shaft 4 which is arranged in the arc-shaped concave cavity 2 and is eccentrically arranged relative to the center of the arc-shaped concave cavity 2, and an arc top lamp shell 5 which is movably sleeved on the connecting shaft 4 and is provided with a lower opening, wherein the arc surface of the upper end of the arc top lamp shell 5 is concentric with the arc surface of the arc-shaped concave cavity 2. Specifically, the lamp body can be turned to directions other than downward irradiation along with the central shaft by adjusting the turning position to the side surface eccentric position, so that the irradiation angle can be enlarged.

The outer side wall surface of the connecting shaft 4 is provided with screw threads along the circumference, a through hole 6 penetrates through the arc-shaped cavity 2 eccentrically relative to the center position of the arc-shaped cavity, the connecting shaft 4 penetrates through the through hole 6, the upper end of the connecting shaft 4 is located on the outer side of the arc-shaped cavity 2 and is in threaded fit with a first limiting part 7, and the lower end of the connecting shaft 4 is located on the inner side of the arc-top lamp shell 5 and is in threaded fit with a second limiting part 8. Specifically, wear to locate in the perforation through the connecting axle to it is spacing with two locating parts through locating part one, so that when the arc lamp body keeps the laminating state with arc cavity inner wall, the arc lamp body is in can be around the rotatory state of connecting axle activity, and the user can adjust the angle of shining of the relative arc cavity of arc lamp body according to the demand, and realizes the fastening through locating part one and locating part two.

The connecting shaft 4 is hollow and tubular in shape. Specifically, the hollow tube is arranged so that a line for connecting the lamp body can penetrate through the cavity of the connecting shaft to the outside for connection.
