Description

A kind of turning structure of lamp holder of track lamp
Technical field
The present invention relates to the turning structure of lamp holder of a kind of track lamp, particularly a kind of track lamp.
Background technology
Track lamp is a kind of light that designs for commercial lighting or merchandise display, and its lamp holder adopts adjustable structure, can make things convenient for the adjustment of lighting angle.
In the prior art, the lamp holder adjustment structure of track lamp has following several usually: 1, directly by screw with lamp body and support pretension.When adopting this structure, can generation directly or indirectly rub between lamp body and the support, the lacquer painting that not only can disfeature to a certain extent, and occur easily to become flexible, need again pretension after the adjusting.2, profile of tooth position limiting structure, namely a pair of flank of tooth is by the screw pretension, and flank engagement forms certain moment of torsion and comes positioning lamp cap.This structure is discontinuous adjustment, and the screw pretightning force is crossed conference and caused lamp holder to rotate, and the too little lamp holder that then can cause of pretightning force can't lock, and, it is bad that the lamp body of this structure and support are connected rigidity, and lamp holder rocks easily, also causes easily tooth surface abrasion to lose efficacy in the rotation process.3, directly riveted joint.This is simple in structure, is applicable to have the light fixture in riveting space, but the bad control of driving torque is relatively poor with the moment of torsion uniformity of batch product, and easily weares and teares in the rotation process, causes lamp holder to fix after the wearing and tearing.
Although more than the lamp holder of several track lamps rotate low, the easy assembling of adjustment structure cost, have following shortcoming: 1, in the adjustment process, the pretension screw is easily loosening, needs again pretension in the use procedure, causes and uses inconvenience; 2, in the adjustment process, the rotation of lamp holder is more stiff, has catching phenomenon, easily loses efficacy after repeatedly regulating; 3, contact-making surface is inhomogeneous, and is easy to wear behind the pivoting friction, the destruction that causes the light fixture outward appearance; 4, rotational structure exposes, and not only destroys overall appearance, and the junction rigidity is relatively poor, easily rocks.
Summary of the invention
Technical problem to be solved by this invention is the turning structure of lamp holder that the good track lamp of a kind of easy to operate and continuous rotation is provided for above-mentioned prior art present situation.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of turning structure of lamp holder of track lamp, it is characterized in that, and include:
