[0002]With the increasing application of lighting fixtures, the lamps used in many occasions are often subject to continuous and strong three-way vibration, but the existing lamps have not yet matched Most of the lamps are rigidly connected and fixed without vibration damping function. Once the lamp is subjected to a large impact or three-way vibration of various irregular frequencies for a long time during the work process, it is easy to cause the bulb, electronic ballast Parts with poor vibration resistance, such as the device, will fall off, break, etc., which will affect the normal use and life of the lamp, and will also cause problems with the electrical connection of the lamp, causing safety hazards

Embodiment Construction
[0023] During production, the housing 11, the elastic member 12 and the connecting member 14 are molded and vulcanized into one body, and the molding manufacturing process is adopted, which not only improves the production efficiency, but also improves the sealing between the outer housing 11, the elastic member 12 and the connecting member 14 property, so that the compressed air filled in the cavity 123 of the elastic member 12 will not leak out through the upper end 111 of the shell 11 .
[0024] Further, as Figure 1 ~ Figure 3 As shown, the lower end 112 of the housing 11 is in sealing connection with a pressure plate 15 , specifically, the lower end 112 of the housing 11 and the pressure plate 15 are fixedly connected by several screws 16 . In order to ensure the sealing performance between the pressure plate 15 and the casing 11, an annular sealing groove 113 is provided at the lower end 112 of the casing 11, and a sealing ring 17 is arranged in the sealing groove 113, a...

The invention is applicable to the antivibration device field and provides a multidirection antivibration vibration absorber. The vibration absorber comprises a shell, wherein the upper end of the shell is open, the lower end is sealed, the inside of the shell is provided with an elastic part with an inner cavity, the outer wall of the elastic part closely sticks to the inner wall of the shell, the upper end of the elastic part is sealed, the lower end is open, the upper end of the elastic part is higher than that of the shell, the upper end of the elastic part is connected with an antivibration product, and an air valve which can be communicated with the cavity of the elastic part is fixedly arranged on the shell. The invention also provides a lamp. The lamp comprises a lamp body, a support arranged on the lamp body and the vibration absorber. When the system which is composed of the vibration absorber and lamp provided by the invention is excited by multidirectional antivibration, the elastic part deforms to compress the air in the cavity so that the air in the cavity of the elastic part is heated, the vibrational energy of the vibration source generates damp heat through the deformation of the elastic part and the heat generated by the air compression of the cavity of the elastic part is gradually lost, thus achieving the aim of reducing the vibration.
Description
technical field [0001] The invention belongs to the field of damping devices, in particular to a multi-directional 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 subject to continuous and strong three-way vibration, but the existing lamps do not have matching shock absorbers, and most of the lamps are rigidly connected and fixed. Vibration reduction function, once the lamp is subjected to large impacts or three-way vibrations of various irregular frequencies for a long time during the working process, it is easy to cause the components with poor vibration resistance such as bulbs and electronic ballasts to fall off, break and other damage. Thereby affecting the normal use and lifespan of the light fixture, also can make the electrical connection of the light fixture go wrong and cause potential safety hazard.
