Abstract
The utility model discloses a disc-type lamp damper which comprises an upper end cover (1), damping rings (2), a spring (8) and a lower end cover (3), wherein the spring (8) and the damping ring (2) are arranged between the upper end cover (1) and the lower end cover (3); connecting rings (4) are respectively connected and fixed to the upper parts and the lower parts of the damping rings (2), and the connecting rings and the spring are respectively connected with the upper end cover and the lower end cover through bolts; threaded holes (5) for fixing a lamp are formed in the upper end cover (1); fixing holes for fixing the lower end cover (3) with a structural part are formed in the lower end cover (3). When the structure is under the actions of impact and vibration, the spring and the damping rings in the lamp damper can be compressed to deform, fully absorb impact and vibration energy, release the impact and vibration energy protractedly, can effectively reduce the impact response of the system, ensure that the lamp works normally under the excitation of the impact and vibration, and prolongs the service life of the lamp.
Description
Technical field
The utility model relates to engineering damping (shaking) field, relates generally to a kind of anti shock and vibration disc type light fixture damper.
Background technology
Light fixture used in daily life is various in style, and the light fixture of considering damping is few, only special use occasion as: the lighting under some vibration environments such as crane gear, walking arrangement, metallurgical equipment, mining equiment, plant equipment, harbour machinery, boats and ships, industrial premises has been considered damping.Because vibration exists under multiple occasion, except the vibration of equipment self operation, also have the rotation of some device interiors also can cause height, middle frequency vibration, and random load can cause low-frequency band random vibration.For the special lamp being arranged on these equipment, unavoidably to be continued, strong vibrational excitation; In addition, also have some vibrations of the intense impact from structural outer, the impact endurance test shock consumingly producing as earthquake and wartime blast etc.Because vibration causes lighting internal light source, damage, and then cause that inner electrical equipment burns out, safety is brought to very large hidden danger.
For conventional light fixture, also there is no supporting light fixture damper at present, even if considered the impact of vibration, the impact that substantially also all adopts the method for reinforced support rigidity to come slowing down vibration to cause, this will cause light fixture weight significantly to increase; And for the light fixture of Special use occasion, part adopts the method vibration isolation of installing rubber shock absorber additional, but can be aging after the long-term use of rubber, and the rigidity of rubber shock absorber is excessive, and the intrinsic frequency of vibrating isolation system is higher, only radio-frequency component is worked, inoperative to intermediate frequency and low-frequency component, amplified on the contrary excitation, in addition, the axial deflection of rubber shock absorber is little, can not effectively alleviate axial impact; Also have some lamp vibration isolators to adopt curved wire rope breeze way to alleviate vibratory impulse, its cost is high, is difficult to apply in ordinary luminaire.
Utility model content
The purpose of this utility model be to provide a kind of simple in structure, cost is low, the disc type light fixture damper of good damping effect.
The purpose of this utility model can adopt following technical scheme to realize: described disc type light fixture damper includes upper end cover, damping ring, spring, bottom end cover, spring and damping ring are arranged between upper end cover and bottom end cover, spring is arranged in damping ring, in damping ring upper and lower, be fixedly connected with respectively connecting ring, connecting ring is connected with upper end cover, bottom end cover respectively by bolt with spring; On described upper end cover, be provided with for the fixing screwed hole of light fixture, on bottom end cover, be provided with for the fixing fixing hole of structure.
Described both ends of the spring is provided with end cap of the spring, is provided with the screwed hole for being fixedly connected with end cap on end cap of the spring.
On described bottom end cover, being useful on the fixing hole fixing with structure is bar hole.
Disc type light fixture damper described in the utility model is less than the light fixture of 200mm mainly for installation diameter, a light fixture can be isolated with a disc type light fixture damper, is connected, then is connected with light fixture by connecting bolt with structure.The utility model is mainly cut down the acceleration peak value of impact shock by spring, damping ring accelerates the decay of vibration, guarantees the normal operation of lighting under impact shock excitation, prolonging service lives of lamps.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is top view of the present utility model.
Fig. 3 is the structural representation of looking up of the present utility model.
In figure: 1, upper end cover, 2, damping ring, 3, bottom end cover, 4, connecting ring, 5, screwed hole, 6, end cap of the spring, 7, dormant bolt, 8, spring, 9, upper end cover dormant bolt, 10, bottom end cover dormant bolt, 11, bar hole.
The specific embodiment
By reference to the accompanying drawings, the utility model is further described.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, 2, 3: described disc type light fixture damper includes upper end cover 1, connecting ring 4, damping ring 2, spring 8, bottom end cover 3.On bottom end cover 3, be provided with bar hole 11, connecting bolt inserts bar hole 11 structures such as disc type light fixture damper and body of wall is connected.Upper and lower two connecting rings 4 and damping ring 2 are passed through to sulfuration or bonding firm, on upper and lower two connecting rings 4, be provided with screwed hole, on upper end cover 1 and bottom end cover 3, be provided with counter sink, with upper end cover dormant bolt 9, upper end cover 1 is connected with top connecting ring, bottom end cover 3 is connected with bottom connecting ring by bottom end cover dormant bolt 10.Spring 8 is arranged in damping ring 2, and spring 8 two ends are provided with plug 6, on plug 6, are provided with screwed hole, on upper end cover 1 and bottom end cover 3, is provided with counter sink, with dormant bolt 7, upper end cover 1 is connected with spring 8 with bottom end cover 3.The support of light fixture is connected with the screwed hole 5 on upper end cover 1 by bolt.
According to the installation dimension of light fixture, disc type light fixture damper is installed structurally, then light fixture is connected with disc type light fixture damper by bolt.When being subject to impact shock, do the used time, spring 8 and damping ring 2 compressions, effectively cushion extraneous impact shock.
