Description

Technical Field

[0001] The present application belongs to the field of lighting technology, and more specifically, relates to a mobile structure and a lamp using the mobile structure. Background Art

[0002] At present, floor lamps usually place the bottom plate of the lamp directly on the ground. When the floor lamp needs to be moved, it needs to be manually carried to the target location, which makes the movement of the floor lamp cumbersome. In order to improve the mobility of the floor lamp, the existing floor lamps usually install universal wheels on the bottom plate of the lamp, so that the floor lamp can be moved in all directions.

[0003] However, when a universal wheel is installed on the bottom plate of the floor lamp, the universal wheel will adjust its position and drive the floor lamp to move in the direction of the external force when the floor lamp is subjected to external force. Since the universal wheel is highly sensitive to external force, a slight external force can push the floor lamp to move, and the stability of the floor lamp cannot be guaranteed. Utility Model Content

[0006] In a first aspect, a mobile structure is provided, comprising:

[0007] Light fixture base plate;

[0008] A roller, rotatably mounted on the bottom plate of the lamp;

[0009] Among them, one end of the lamp base plate is in contact with the supporting surface, and the roller is arranged at the other end of the lamp base plate, and the roller is in contact with the supporting surface.

[0010] In one embodiment, a first receiving groove for receiving the roller is provided on the bottom plate of the lamp, a first rotating shaft is installed in the first receiving groove, two ends of the first rotating shaft are rotatably installed on two opposite inner walls of the first receiving groove respectively; the roller is installed on the first rotating shaft.

[0016] In one embodiment, there are multiple rollers, and the multiple rollers are distributed on the bottom plate of the lamp in a circular array.

[0017] In a third aspect, a mobile structure is provided, comprising:

[0018] Light fixture base plate;

[0019] A roller, rotatably mounted on the bottom plate of the lamp;

[0020] Among them, the lamp base plate is arranged parallel to the supporting surface and spaced apart, and a plurality of the rollers are installed in a circular array on the lamp base plate, and each of the rollers is in contact with the supporting surface; the rolling directions of the plurality of rollers intersect at an intersection point on the lamp base plate.

[0021] In one embodiment, a second accommodating groove for accommodating the roller is provided on the bottom plate of the lamp, a third rotating shaft is installed in the second accommodating groove, two ends of the third rotating shaft are respectively rotatably installed on two opposite inner walls of the second accommodating groove, and the roller is installed on the third rotating shaft; the central axes of multiple third rotating shafts intersect at the intersection point.

[0022] In one embodiment, the cross section of the roller is elliptical, and an annular plane is provided in the middle of the outer peripheral surface of the roller along the circumferential direction.

[0023] In a fourth aspect, a lamp is provided, comprising a lamp body and a movable structure provided by any one of the above embodiments, wherein the lamp body is mounted on the lamp base plate.

[0025] The mobile structure and the lamp provided by the embodiments of the present application have at least the following beneficial effects:

[0026] 1. The present application makes one end of the lamp base plate contact with the support surface, and a roller is rotatably installed at the other end of the lamp base plate, and the roller contacts the support surface. When the lamp base plate is subjected to an external force along the rotation direction of the roller, the friction resistance between the lamp base plate and the support surface can offset the smaller external force, thereby overcoming the defect that the lamp is easy to slide under the action of a smaller external force.

[0027] 2. In this application, the bottom plate of the lamp is placed on the support surface, and the roller on the bottom plate of the lamp does not contact the support surface.

In this structure, the roller 3 can be accommodated through the second accommodating groove 27 to reduce the occupied space of the lamp base plate 2. By fixing the roller 3 on the third rotating shaft 28, the third rotating shaft 28 can be driven to rotate on the lamp base plate 2 when the roller 3 rotates.
