Vibration absorber with unidirectional vibration prevention and lamp using same

Abstract

The invention is suitable for the field of vibration dampers and provides a vibration absorber with unidirectional vibration prevention, which comprises an outer casing. The upper end of the outer casing is fixedly connected with an end cover, and the lower end is fixedly connected with a vibration-prevention product. Liquid is loaded in the outer casing. A piston is immersed into the liquid, and is provided with a plurality of flow guiding holes. The piston is fixedly connected with the piston rod. The piston rod glidingly penetrates through the end cover. At least one elastic element is arranged between the piston and the end cover. The invention also provides a lamp comprising the vibration absorber. The lamp is hung under the vibration absorber. When the vibration absorber is subject to the unidirectional vibration along the axial direction, the lamp and the vibration absorber move along the piston rod up and down, the liquid in the outer casing flows in the flow guiding holes of the piston and the inner edges of the outer casing, and then the vibration energy is converted into the mechanical energy and heat energy of the liquid flowing backwards and forwards to be gradually consumed, thus the invention achieves the purpose of unidirectional vibration reduction, ensures the normal use of the lamp, and prolongs the service life of the lamp.

Description

technical field [0001] The invention belongs to the field of damping devices, in particular to a one-way anti-vibration damper and a lamp using the damper. Background technique [0002] With the increasingly wide application of lighting fixtures, the lamps used in many occasions are often subjected to continuous and strong vibrations, but the existing lamps lack effective anti-vibration measures. Most of the lamps are rigidly connected and fixed without vibration reduction. function, once the lamp is subjected to large impacts or vibrations of various irregular frequencies for a long time during the working process, it is easy to cause the bulbs, electronic ballasts and other parts with poor vibration resistance to fall off, break and other damages, thus affecting the performance of the lamp. Normal use and lifespan will also cause problems with the electrical connection of the lamps and cause potential safety hazards. Contents of the invention [0003] The purpose of the...
