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.

Refer to Fig. 1 to Fig. 2, the invention provides a kind of light fixture, light fixture comprises a lamp adapter assembly 1, a bulb assembly 2, a big spring 3 and a lamp cylinder 4, can also comprise a battery 5.

Lamp adapter assembly 1, lamp adapter assembly 1 comprises a reflector 12, at least one bead 13, one bow spring 14 and a front casing assembly 11, reflector 12 comprises that taper seat 121 and that a top has through hole is by the through hole of taper seat 121 installation portion 122 forming that stretches out, installation portion 122 pressed on rings have got around a locating slot 1222, in locating slot 1222, have at least one the first locating hole 1221, on bow spring 14, have at least one the second locating hole 141 matching with the first locating hole 1221, bow spring 14 is engaged in locating slot 1222 and makes the first locating hole 1221 and the second locating hole 141 aligns, the diameter of the second locating hole 141 is less than the first locating hole 1221, bead 13 is fixed in the first locating hole 1221 and the second locating hole 141, reflector 12 is set in front casing assembly 11.

In the present embodiment, front casing assembly 11 comprises a shell 111, a sealing ring 112, a sheet glass 114 and a trim ring 113, shell 111 is formed by connecting by the cylindricality head and the tail of the different hollow of two diameters, sealing ring 112 is set in the side that the diameter of shell 111 is larger, sheet glass 114 lids are pressed on sealing ring 112 and are positioned at and more approach the larger opening part of shell 111 diameters, trim ring 113 is set in shell 111 and pressed glass sheet 114, the side connecting lamp cylinder 4 that shell 111 diameters are less.In other embodiments, the structure of front casing assembly 11 can be other form, as long as can coordinate reflector 12 normal connecting lamp cylinder 4.In the present embodiment, in the larger cylindricality of the diameter of shell 111, be provided with a centring ring 1112, sealing ring 112 is set on centring ring 1112.In other embodiments, sealing ring 112 can be secured on shell 111 by alternate manner.In the present embodiment, in the larger cylindricality of the diameter of shell 111, be provided with a spacing collar 1111, spacing collar 1111 is positioned at the below of sealing ring 112, in order to spacing reflector 12.When reflector 12 is sheathed while entering in shell 111, spacing collar 1111 blocks reflector 12 around from reflector 12, can play like this restriction reflector 12 position diametrically, and because reflector 12 is tapers, so spacing collar 1111 can limit again the position of reflector 12 in the axial direction.In other embodiments, can engage or fixture is fixing etc. that mode is carried out spacing reflector 12 by draw-in groove.In the present embodiment, bead 13 is steel ball, and the quantity of steel ball, the first locating hole 1221 and the second locating hole 141 is three.In other embodiments, bead 13 can be other material, and the quantity of bead, the first locating hole 1221 and the second locating hole 141 can adjust as required, for example, increase into four, five or six.In the present embodiment, the material of sealing ring 112 is silica gel.In other embodiments, the material of sealing ring 112 can require to replace according to other.

Bulb assembly 2, bulb assembly 2 comprises a bulb 21 and a little spring 22, and little spring 22 is fixedly connected with the bottom of bulb 21, and bulb 21 inserts and clamps in the through hole that is fixed on reflector 12.In the present embodiment, bulb 21 comprises a bulb body 211 and a bulb housing 212, and insert in bulb housing 212 bottom of bulb body 211, and the bottom of bulb housing 212 stretches out and forms a positioning bar 2121, limit rib 2121 conflict installation portions 122.Bulb body 211 and bulb housing 212 can be the one-body molded bulbs of directly buying, two elements assembling again can be also use time.The effect of limit rib 2121 be in the time that bulb 21 inserts through hole by limit rib 2121 conflict installation portions 122 stop bulb 21 excessive enter into through hole, thereby avoid installing dislocation.In the present embodiment, the material of little spring 22 is copper wire nickel plating, and in other embodiments, little spring 22 can be other conductive material.

Big spring 3, the installation portion 122 of reflector 12 inserts in big spring 3, and the diameter of a minimum circle of big spring 3 is just a bit larger tham installation portion 122, and big spring 3 and installation portion 122 have just clamped like this.

Lamp cylinder 4, front casing assembly 11 connecting lamp cylinders 4.In the present embodiment, in the less cylindricality of the diameter of shell 111, have internal thread, on lamp cylinder 4, have external screw thread with shell 111 junctions, shell 111 and lamp cylinder 4 are connected by internal thread and external screw thread.In other embodiments, also can replace with on shell 111 and offer external screw thread, on lamp cylinder 4, offer the mode of internal thread, or adopt the modes such as draw-in groove engaging to come connected with outer casing 111 and lamp cylinder 4.

Battery 5, battery 5 is arranged in lamp cylinder 4, battery 5 conflict big springs 3 and little spring 22.

Below take the present embodiment as example describes in detail operation principle of the present invention.

Bead 13 is in the first locating hole 1221, because the diameter of the second locating hole 141 is less than the first locating hole 1221, so bead 13 cannot outwards drop out, bead conflict bulb 21 in the time that bulb 21 inserts in the through hole of reflector 12, but bead 13 cannot outwards drop out, this just makes bead 13 clamp bulb 21, has so just increased the clamping degree of bulb 21 in reflector 12 through holes.In the time that light fixture is subject to the vibration of sagittal plane, bow spring 14 can absorb part vibration, and in the time that light fixture is subject to axial vibration, big spring 3 can absorb part vibration, and both actings in conjunction can solve the vibration damping problem without lamp socket light fixture like this.And when need to more change the bulb be, only lamp adapter assembly 1 need to be pulled down, then by bulb assembly 2 from the through hole of reflector 12 from extracting out, very convenient, so just solved the replacing problem without the bulb of lamp socket light fixture.

In sum, the present invention by bow spring absorb the vibration of sagittal plane and big spring absorption axes to vibration, meet the fixing vibrationproof requirement without lamp socket bulb, and the mode of inserting the through hole of the installation portion of reflector by bulb fixes bulb, meet the requirement that bulb is convenient for changing, thereby fixed vibrationproof and be convenient for changing two requirements without simultaneously satisfied under holder structure.

The foregoing is only better possible embodiments of the present invention, not limit the scope of the invention.Every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do, or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
