Problems solved by technology
However, the defect of the rubber vibration damping device is that it has poor vibration reduction performance for low frequency and large amplitude. Under the impact of low frequency and large amplitude, the rigidity of the rubber is weak, and a large vibration displacement will occur, resulting in equipment damage and poor vibration damping effect.

The invention is applicable to the technical field of shock absorption structures, and discloses a shock absorber and a lamp comprising the shock absorber. The shock absorber comprises a base, an installation plate, and a first rubber shock absorption pad, a second rubber shock absorption pad and a plurality of springs; the first rubber shock absorption pad and the second rubber shock absorption pad are overlapped and are sandwiched between the base and the installation seat; the first rubber shock absorption pad is provided with a plurality of convex posts in a convex way; the ends of the first convex posts are pressed against the second rubber shock absorption pad; the springs are sleeved on the first convex posts; one ends of the springs are pressed against the first rubber shock absorption pad; the other ends of the springs are pressed against the second rubber shock absorption pad. The lamp comprises a lamp holder and the shock absorber. The shock absorber provided by the invention and the lamp comprising the shock absorber have good shock absorption effects on low-frequency, medium-frequency and high-frequency shock; the shock absorber can be applicable to the place with wide shock frequency, so as to prevent equipment, instrument and lamps from being damaged due to vibration in various vibration environments.
Description
technical field [0001] The invention belongs to the technical field of vibration-damping structures, and in particular relates to a vibration-damping device and a lamp including the vibration-damping device. Background technique [0002] In the case of strong environmental vibration, a vibration damping device is needed to reduce the impact of external vibration on instruments and equipment. In the prior art, the damping device on the lamp generally simply uses rubber as the damping medium. However, the defect of the rubber damping device is that it has poor vibration reduction performance for low frequency and large amplitude. Under the impact of low frequency and large amplitude, the rubber rigidity is weak, and a large vibration displacement will occur, resulting in equipment damage and poor vibration damping effect. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a vib...
