Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
See Fig. 1 and Fig. 2, the lighting bracket adjustment structure of the present embodiment comprise be provided with the first through hole 11 support 1, be provided with the second through hole 21 and first damping piece 2 fixing with support 1, be provided with third through-hole 31 the second damping piece 3, be provided with fourth hole 41 and the light fixture end cap 4 fixing with the second damping piece 3, be provided with the first screwed hole 51 connecting plate 5, for successively through the first screw rod 6 that the first through hole 11, second through hole 21, third through-hole 31, fourth hole 41 and the first screwed hole 51 are locked; The second above-mentioned damping piece 3 is closely socketed in the outer wall of the first damping piece 2, and and can relatively rotate between the first damping piece 2.First damping piece 2 and the second damping piece 3 construct damping mechanism, be locked with connecting plate 5 by the first screw rod 6, produce pretightning force, make to produce between the first damping piece 2 and the second damping piece 3 certain frictional force to reach angle and fix, and the first damping piece 2 and support 1 are fixed, second damping piece 3 is fixed with light fixture end cap 4, when certain torsion is applied to light fixture end cap 4, light fixture end cap 4 rotates relative to the first damping piece 2 with the second damping piece 3, and support 1 and the first damping piece 2 motionless, reach and relatively rotate, realize the adjustable of angle.Solve in prior art the inconvenience needing first to unclamp bolt and just can carry out regulating before adjustment.
The first damping piece 2 in the present embodiment and the fixed form between support 1 be in the following way: on the end face of the first damping piece 2, arrange several the first projections 12 extended toward the first damping piece 2 direction at support 1, and the first damping piece 2 is provided with accordingly on the end face near support 1, and several are equal with the quantity of the first projection 12 with the quantity of the first groove 23, the first groove 23 that the first projection 12 mates.Matched with the first groove 23 by the first projection 12, avoid when adjustment angle, the first damping piece 2 produces relative motion with support 1.Equally, second damping piece 3 with the fixed form of light fixture end cap 4 is, light fixture end cap 4 is provided with the second projection 42 that several extend toward the second damping piece 3 direction, second damping piece 3 is provided with several the second grooves 32 mated with the second projection 42 near the end face of light fixture end cap 4, the quantity of the second groove 32 is equal with the second projection 42, second projection 42 and the second groove 32 mate work, mutual clamping, avoid when adjustment angle, relative motion between the second damping piece 3 and light fixture end cap 4, ensures that whole lighting bracket adjustment structure effectively works.
Owing to producing noise when relatively rotating between the first damping piece 2 and the second damping piece 3 during for effectively reducing adjusting angle, the lateral wall that first damping piece 2 contacts with the second damping piece 3 arranges several the 3rd grooves 22,3rd groove 22 is evenly distributed on lateral wall circumferentially, by setting up the 3rd groove 22, make to increase cross-ventilation between the first damping piece 2 and the contact surface of the second damping piece 3, decreasing the continuous print friction between contact surface when rotating, effectively reducing noise.
The lighting bracket adjustment structure of the present embodiment is locked with connecting plate 5 due to the first screw rod 6, and during adjusting angle, the first damping piece 2 rotates relative to the second damping piece 3, the first screw rod 6 and connecting plate 5 motionless.For avoiding because the first screw rod 6 is excessive with connecting plate 5 locking force, when adjusting angle, when rotating light fixture end cap 4, connecting plate 5 also and then relatively rotates, connecting plate 5 arranges the second screwed hole 52 more, and is revolved due to the second screwed hole 52 by the second screw rod 7, and the second screw rod 7 touches light fixture end cap 4, adding the pretightning force between connecting plate 5 and light fixture end cap 4, preventing light fixture end cap 4 and connecting plate 5 when rotating from producing relative rotation.
Overall, the beneficial effects of the utility model are:
1, be locked with connecting plate 5 by the first screw rod 6, produce certain frictional force between first damping piece 2 and the second damping piece 3 to reach angle and fix, because the first damping piece 2 is fixed with support, second damping piece 3 is fixed with light fixture end cap 4, apply certain torsion and rotate light fixture end cap 4, when torsion is greater than the frictional force between the first damping piece 2 and the second damping piece 3, the angle of adjustable luminaire, easy to operate, practical.
2, the 3rd groove 22 is set at the lateral wall of the first damping piece 2, cross-ventilation is increased thus between first damping piece 2 and the contact surface of the second damping piece 3, decrease the friction between contact surface, during rotation, effectively can reduce the noise produced between the first damping piece 2 and the second damping piece 3.
3, increase by the second screw rod 7, second screw rod 7 to contact with light fixture end cap 4, increase connecting plate 5 and the pretightning force of light fixture end cap 4, avoid driving when the first damping piece 2 and the second damping piece 3 produce and rotate connecting plate 5 and light fixture end cap 4 also to produce relative rotation.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
