Detailed Description

The present invention will be described in detail below with reference to specific embodiments shown in the drawings. However, these embodiments are not intended to limit the present invention, and structural, methodical, or functional changes that may be made by one of ordinary skill in the art based on these embodiments are all included in the scope of the present invention.

Referring to fig. 1 to 5, a track lamp includes a track 1, a lamp holder 2, and a lamp body 3, wherein the track 1 is fixedly installed on a wall, a guide groove 11 having a T-shaped cross section is formed in the track 1, the lamp holder 2 has an i-shaped cross section, and a plurality of rollers 4 are disposed on a bearing surface of the lamp holder 2, which is matched with the guide groove 11.

The lamp holder 2 is mounted on the guide groove 11 of the rail 1, the weight of the lamp holder 2 is supported by the rollers 4 on the lamp holder 2, and the lamp holder 2 is in rolling contact with the guide groove 11, so that the moving resistance of the lamp holder 2 is small.

Still include drive mechanism, drive mechanism includes rack 61, first gear 62, rotation axis 63, hand wheel 64, rack 61 is fixed to be set up track 1 bottom and edge the length direction of guide slot 11 extends, first gear 62 with the meshing of rack 61 insection sets up, rotation axis 63 with the coaxial fixed setting of first gear 62, rotation axis 63 wears to establish on lamp stand 2, the one end of rotation axis 63 extends to the lamp stand 2 outside and coaxial fixed connection hand wheel 64.

When the position of the lamp holder 2 on the track 1 needs to be adjusted, the hand wheel 64 is rotated, the hand wheel 64 drives the first gear 62 to rotate through the rotating shaft 63, and the first gear 62 rolls along the rack 61 in the rotating process, so that the lamp holder 2 is driven to move. Compared with the mode that the lamp holder 2 is directly pushed and pulled by hands to move, the lamp holder 2 is driven by the transmission mechanism to move, so that the stroke of the lamp holder 2 is more conveniently and accurately controlled.
