Detailed description of the invention
In order to further illustrate principle of the present invention and structure, below in conjunction with accompanying drawing, to a preferred embodiment of the present invention will be described in detail.
Accompanying drawings 1 to Fig. 5, light fixture of the present invention roughly comprises: upper casing 1, lower casing 2, inflating rubber ring 3, spring 4, coupling assembling 5, mounting bracket 6 and a lamp holder 7.This light fixture can be attached in an installment surface 8.Wherein, this upper casing 1, lower casing 2, inflating rubber ring 3, spring 4, coupling assembling 5 and mounting bracket 6 match and form light fixture shock-damping structure of the present invention.
Accompanying drawings 5, the sidewall 12 that this upper casing 1 has a roof 11 and stretched out downwards by described roof 11 periphery.The central authorities of described roof 11 are provided with one second through hole 111.Wherein, this roof 11 is rounded, and sidewall 12 cylindrically.
Accompanying drawings 3, accompanying drawing 4 and accompanying drawing 5, the sidewall 22 that this lower casing 2 has a diapire 21 and upwards stretched out by described diapire 21 periphery.The central authorities of described diapire 21 are provided with one first through hole 211.Wherein the diapire 21 of this lower casing 2 is rounded, and sidewall 22 is cylindrical.In the present embodiment, the diameter of the roof 11 of described upper casing 1 is less than the diameter of the diapire 21 of described lower casing 2, thus the socket of the sidewall 12 of described upper casing 1 is installed on sidewall 22 inside of described lower casing 2.The diapire 21 of wherein said lower casing 2 extends multiple supporting leg 23 downwards.In the present embodiment, described supporting leg 23 is provided with two, the diapire 21 being located at described lower casing 2 of its symmetry.The end of described supporting leg 23 is provided with a land portion 231, described light fixture shock-damping structure can be fixed on the fixed position place of applied environment by this land portion 231, and described land portion 231 extends outward sidewall 22, so, the stability of whole light fixture shock-damping structure can be increased.Wherein, the center of the diapire 21 of described lower casing 2 is provided with one first through hole 211, and after together with described upper casing 1 is assembled with lower casing 2, the axial line of the first described through hole 211 overlaps with the axial line of the second described through hole 111.
Accompanying drawings 4 and accompanying drawing 5, the material that this inflating rubber ring 3 adopts elasticity larger is made, and inside can be filled with appropriate gas, and the amount of insufflation gas is determined according to the needs of the environment of light fixture work.Wherein, the height of the sidewall 12 of upper casing 1 described in the vertical aspect ratio of described inflating rubber ring 3 under not subjected to pressure state wants large.That is, when described upper casing 1 and lower casing 2 under the effect in external force, first by this inflating rubber ring 3 pressurized damping, described inflating rubber ring 3, as first order damping portion, can not allow upper casing 1 directly firmly contact with lower casing 2.
Accompanying drawings 4 and accompanying drawing 5, this spring 4 is installed in the inner ring of this inflating rubber ring 3.Further, the natural extended length of described spring 4 is less than the height of described inflating rubber ring 3 under not subjected to pressure state; And described spring 4 is larger than the described height of inflating rubber ring 3 under maximum pressured state in the length of maximum pressured state.Namely, when light fixture is subject to extraneous impact time, described inflating rubber ring 3 is first as first order damping portion, and described spring 4 is as second level damping portion, under limiting condition, inflating rubber ring 3 compressive deformation, now described spring 4 plays a role as second level damping portion, described inflating rubber ring 3 excessive deformation can be avoided even to be damaged, thus the anti-seismic performance of described light fixture shock-damping structure can be strengthened.
Accompanying drawings 3, accompanying drawing 4 and accompanying drawing 5, this coupling assembling 5 comprises: a stud 51 and one and the matched nut 52 of described stud 51.Described stud 51 is from the bottom up through the first through hole 211 on described lower casing 2 and the second through hole 111 on described upper casing 1, and the nut 52 described in upper end screws in carries out connection locking.Wherein, described spring 4 is set on stud 51, and inflating rubber ring 3 is set on spring 4 further.
Accompanying drawings 5, the supporting leg 62 that this mounting bracket 6 comprises a gripper shoe 61 and extended downwards by described gripper shoe 61 two ends.Two described supporting legs 62 are fixed on the roof 11 of described upper casing 1.Described gripper shoe 61 is evenly provided with three installing holes 611.Wherein, be positioned at a middle installing hole 611 to be just in time positioned at above the axis of described first through hole 211 and the second through hole 111.
Accompanying drawings 1, this lamp holder 7 is installed on the installing hole 611 on the mounting bracket 6 of this upper casing 1.When lamp holder 7 is fixed in an antidetonation environment, this light fixture shock-damping structure just can play certain protective effect to lamp holder 7.
Shock-damping structure of the present invention has the shock-damping structure that inflating rubber ring adds spring composition, can adapt to the vibration environment of Various Complex by available protecting light fixture.Adopt this shock-damping structure, light fixture can be made at the environment of judder, as bank bridge, straddle truck, when large automobile uses, the light source of light fixture is not shattered.Well add product reliability.This kind of invention, can be generalized to automotive field, undercarriage etc., can use for large-scale shock-absorption device, range of application is wider.
It is important to note that the upper casing 1 cooperatively interacted described in the present embodiment and lower casing 2 adopt is all that tubular structure matches, in other embodiments, described upper casing 1 and lower casing 2 corresponding thereto also can be other shapes such as cube.
These are only better possible embodiments of the present invention, not limit the scope of the invention, all utilizations description of the present invention and the change of the equivalent structure done by accompanying drawing content, be all included in protection scope of the present invention.
