Description of drawings
To combine accompanying drawing and embodiment that the present invention is described further below, in the accompanying drawing:
Fig. 1 is the decomposing schematic representation of lamp shock absorber of the present invention;
Fig. 2 is the sketch map after the lamp shock absorber assembling of the present invention;
Fig. 3 is the cutaway view of lamp shock absorber of the present invention.
The specific embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3, in an embodiment of lamp shock absorber of the present invention, connecting rod 10 has baffle plate 11, and baffle plate 11 is divided into first section 12 and second sections 13 with connecting rod 10; First elastic cylinder 20 and second elastic cylinder 21 have the through hole adaptive with connecting rod on the axis of himself; First elastic cylinder 20 is set on first section 12; This first elastic cylinder 20 contacts with baffle plate 11; Second elastic cylinder 21 is set on second section 13, and this second elastic cylinder 21 contacts with baffle plate 11; The connecting rod 10 and first elastic cylinder 20 and second elastic cylinder 21 are positioned at housing 30; Housing 30 has an openend; This openend cover plate 31 that is connected, cover plate 31 is encapsulated in connecting rod 10 and first elastic cylinder 20, second elastic cylinder 21 in the housing 30, and the other end of housing 30 has first through hole 32; Pass by first through hole 32 for first section 12, be connected with external equipment with convenient.In the present embodiment; First elastic cylinder 20 and second elastic cylinder 21 all are the cylinder of rubber material, and it is multidirectional shockproof mainly to rely on its bigger modulus of elasticity in comperssion to realize, when shock absorber receives the vibration of connecting rod 10 axial directions; Rely on baffle plate 11 extruding first elastic cylinders 20 or second elastic cylinder 21 to come buffering vibration; Vibration is produced damping action, and when shock absorber received the vibration of connecting rod 10 radial direction, connecting rod 10 radially pushed first elastic cylinder 20 and second elastic cylinder 21; Thereby the vibration of buffering radial direction is to the vibration generation damping action of this direction.When vibrating, can it be decomposed into the vibration of radial direction and axial direction, and it is produced damping effect from a plurality of direction.
In the present embodiment; First elastic cylinder 20 and second elastic cylinder 21 and housing 30 interference or interference fits; Preferred interference fit; Such first elastic cylinder 20 and second elastic cylinder 21 are pressed into housing 30 backs and are difficult for taking place to become flexible, and also have certain predeformation in addition, can be better shockproof.
In the present embodiment; For the sealing between first section 12 and the housing 30; Simultaneously also be for connecting rod 10 can better be supported when vibration and the deflection that receives radially, between first section 12 and first through hole 32, be provided with rubber seal 40, the periphery of rubber seal 40 has an annular groove 41; The edge card of first through hole 32 is in annular groove 41; Rubber seal 40 and first section 12 interference or interference fits, when shock absorber received radial vibration, rubber seal also can play certain vibration isolating effect for 40 pairs first section 12.
In the present embodiment, being connected of shock absorber and light fixture for ease, first section 12 keyset 50 that is connected of connecting rod 10, this keyset 50 is provided with a plurality of installing holes 51, is used for fixing light fixture.
In the present embodiment, be connected through rivet 312 riveted joints between the housing 30 of shock absorber and the cover plate 31, in practical application, also can adopt other connected mode; For example connect through modes such as screw connections; Shock absorber is fixing for ease, and the openend on its housing 30 extends outward brace 33, and it is provided with installing hole 34; Cover plate 31 correspondence positions also are provided with installing hole 311, can easily shock absorber be fixed on needed position through installing hole 34,311.
Interfere with cover plate 31 for fear of second section; The height of second elastic cylinder 21 is greater than said second section 13 length; Make baffle plate 11 when compression second elastic cylinder 21, second section 13 can not interfere with cover plate 31 yet, can the damping property of shock absorber do not impacted.
Combine accompanying drawing that embodiments of the invention are described above; But the present invention is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, also can make a lot of forms, these all belong within the protection of the present invention.
