The specific embodiment

In order to further illustrate principle of the present invention and structure, existing by reference to the accompanying drawings to a preferred embodiment of the present invention will be described in detail.

Consult Fig. 1, a kind of antivibration lamp comprises: lamp outer casing 3, be arranged on bulb 2 in lamp outer casing 3 and in order to the fixing support 1 of bulb 2.

In conjunction with consulting Fig. 1 and Fig. 2, support 1 comprises: a filler ring 11 and one group of shell fragment 12 being arranged on filler ring 11.

Filler ring 11 can be preferably stainless steel, and it comprises: a base 115, the ring body 111 being connected with base 115 and are in order to lock the securing member 114 of ring body 111.Base 115 is formed by ring body 111 one bendings, the bottom of ring body 111 is established opening and is formed two links at opening part, this two link respectively bending downwards extends to form two linking arms 1121, two linking arms 1121 extend and formation two top arms 1131 along contrary direction bending respectively again, two top arms 1131 are distinguished bending downwards again and are extended and formation two side arms 1132, two side arms 1132 lower end doublings formation one end arm 1133 that overlaps.Two top arms 1131, two side arms 1132 and an end arm 1133 form a square base portion 113, two linking arms 1121 are between ring body 111 and base portion 113, form a neck 112, base portion 113 and neck 112 form jointly in order to support the base 115 of ring body 111.The end arm 1133 of base portion 113 is provided with installing hole 1134, support 1 is fixed on lamp outer casing 3 by this installing hole 1134.Securing member 114 consists of a screw 1141 and a nut 1142, on two linking arms 1121 of neck 112, a perforation 1122 is respectively set, and screw 1141 is locked by nut 1142 through perforation 1122 and traversing through end on two linking arms 1121.Fastening nut 1142 can make two linking arms 1121 mutually close, and then drives the opening bore of ring body 111 bottoms to reduce, thereby ring body 111 internal diameters are dwindled; Unclamp nut 1142 and can make two linking arms 1121 rebound and keep certain distance, and then drive the opening of ring body 111 bottoms to increase, thereby ring body 111 internal diameters are expanded.

In conjunction with consulting Fig. 2, Fig. 4, Fig. 5 and Fig. 6, this group shell fragment 12 being circumferentially uniformly distributed along ring body 111 on filler ring 11.Shell fragment 12 can be preferably stainless steel, it comprises: a fixed part 121 and the clamping part being formed by crooked extension the in one end of fixed part 121, fixed part 121 and clamping part are encircled into an opening, and clamping part comprises: the bending section 122 being connected with fixed part 121 and the tilting section 123 being connected with bending section 122.Two relative ends of 123 weeks causes of tilting

section

1231,1232 are surrounded and are formed with two

relative sidepieces

1233,1234, tilting section 123 tilts with respect to fixed part 121, and tilting section 123 near one end 1231 of bending section 122 to the other end 1232 gradually away from fixed part 121, tilting section 123 also from one side 1234 to opposite side 1233 gradually away from fixed part 121.When shell fragment 12 is connected with ring body 111, the opening of shell fragment 12 is aimed to ring body 111, ring body 111 is clipped between the fixed part 121 and clamping part of shell fragment 12, and fixed part 121 is positioned at the outside of ring body 111 and is connected with ring body 111 by screw 121, retaining part is in the inner side of ring body 111 and unsettled with respect to ring body 111.

Consult Fig. 1, bulb 2 is elongated tubular, and its head end is inserted in the lamp socket 313 of lamp outer casing 3, and tail end is inserted in the ring body 111 of support 1, and is fixed on lamp outer casing 3 by support 1.

Consult Fig. 1 and Fig. 3, in lamp outer casing 3, there is the accommodating cavity 31 that holds bulb 2, on the sidewall of accommodating cavity 31, be provided with the lamp socket 313 in order to plug-in mounting bulb 2, on the diapire of accommodating cavity 31, there is fluting 311, in fluting 311, be provided with the fixed station 312 in order to connection bracket 1, fixed station 312 upper surfaces are outwardly in fluting 311, and the upper surface of fixed station 312 is provided with the installing hole in order to fixed support 1.

During assembling, first the head end of bulb 2 is inserted in lamp socket 313, screw bulb 2, then the ring body 111 of having riveted the support 1 of shell fragment 12 is enclosed within to the tail end (noticing that the opening of shell fragment 12 is towards the tail end of bulb) of bulb 2, traversing carriage 1 again, the installing hole that installing hole 1134 on 1 end of support arm 1133 is aimed on fixed station 312, then with screw support 1, be fixed on the fixed station 312 of lamp outer casing 3, finally use the neck 112 of securing member 114 lock brackets 1, make shell fragment 12 compression clamping bulbs 2, so far just completed the assembling of bulb 2.

The principle of bulb 2 vibrationproof: when lamp installation environment has vibration; bulb 2 can be along with vibration; but because bulb 2 is distributed on a plurality of shell fragments 12 clampings on support 110 ring bodies 111; and shell fragment 12 elastically deformables; so when bulb vibrates, the strain of shell fragment 12 has cushioned the vibration of bulb 2, therefore; effectively protected bulb 2, prevented that bulb 2 from breaking because of vibration.

It should be noted that, these are only better possible embodiments of the present invention, not limit the scope of the invention, the equivalent structure that all utilizations description of the present invention and accompanying drawing content have been done changes, and is all included in protection scope of the present invention.
