Wherein, described lamp holder profile is the convex of being made up of small cylinder and large cylinder, extend the clamping hook arm of at least two interval suitable distances along described lamp holder length direction to described large cylinder inner chamber by described small cylinder perisporium, described clamping hook arm end forms grab to described large cylinder inwall one side, offers corresponding bayonet socket on described light fitting body; The end that described clamping hook arm is connected with described small cylinder is positioned on the described small cylinder perisporium and the connecting portion of itself and described large cylinder and described small cylinder has suitable distance, and the dual-side of described clamping hook arm is not connected with large cylinder with described small cylinder.

Wherein, be arranged with a flexible rings on described small cylinder periphery wall, corresponding described clamping hook arm position is provided with corresponding projection on described flexible rings.

Described lamp holder profile is the hollow circular cylinder of an end opening, to its port elongation moulding clamping hook arm is arranged in described lamp holder inside, and the free end of described clamping hook arm forms grab; Offer through hole on the described lamp holder perisporium corresponding to described clamping hook arm appropriate position, form projection on the described clamping hook arm, described projection passes described through hole makes its part be positioned at the described lamp holder perisporium outside.

Be arranged with a flexible rings on described lamp holder periphery wall, form the groove corresponding to described projection on the described flexible rings, described projection embeds in the described groove.

The grab of the utility model by the lamp holder inner chamber is stuck in the bayonet socket on the light fitting body, realize that the lamp holder locking is on light fitting body, when needs disassemble lamp holder, by in the lamp holder lateral, pushing grab, make grab break away from bayonet socket, take off then that lamp holder keeps in repair or work such as bulb replacement, realized the installing/dismounting of lamp holder very easily, prolong the useful life of fluorescent tube, reduced the discarded rate of fluorescent tube, effectively protected environment; And holder structure processing of the present utility model is simple, can pass through the Shooting Technique one-shot forming.

Embodiment

At the utility model structure, now lift a preferred embodiment and describe in conjunction with graphic: holder structure comprises light fitting body 1, is installed in the holder structure 2 of light fitting body 1 end, and its concrete structure is as follows:

Lamp holder 2, referring to Fig. 1～Fig. 4, its profile is convex, be plastic material, the inner hollow injection structure that combines by small cylinder 3 and large cylinder 4, the perisporium coupling of the perisporium of its large cylinder 4 and light fitting body 1, when assembling, but large cylinder 4 inside of the end recessed luminaire header structure of light fitting body 1; Extend at least two clamping hook arms 31 apart from the perisporium of large cylinder 4 end certain distances to large cylinder 4 inner chambers from small cylinder 3, each clamping hook arm interbody spacer distance, this clamping hook arm 31 does not stretch out the holder structure opening part; Free end end at clamping hook arm 31 forms grab 32 to large cylinder perisporium one side, form certain gradient between end that this grab 32 and clamping hook arm 31 are formed and large cylinder perisporium, help light fitting body in the recessed luminaire header structure time, enter smoothly between clamping hook arm and the large cylinder perisporium; The other end of clamping hook arm 31 and small cylinder are connected to an integral body, and the dual-side of clamping hook arm 31 is free margins, and when pushing the outer surface of the clamping hook arm 31 that is positioned at the small cylinder place, the free end of clamping hook arm 31 can inwardly move along with pressing force;

Light fitting body 1 referring to Fig. 6, offers corresponding bayonet socket 11 in clamping hook arm 31 positions of the corresponding holder structure 2 in the end of light fitting body 1, and back rotation lamp holder sticks in the bayonet socket 11 grab lamp holder is locked on light fitting body in light fitting body 1 embeds lamp holder;

Periphery at the small cylinder 3 of holder structure 2 also can be arranged with a rubber-like flexible rings 5, can adopt the rubber material referring to this flexible rings of Fig. 5; On the periphery wall of flexible rings 5, be provided with and push projection 51 accordingly corresponding to the position of clamping hook arm, referring to Fig. 6, when the periphery that flexible rings 5 is set in small cylinder 3, the projection 51 of pushing on the flexible rings 5 is positioned on the position of clamping hook arm 31, by pushing projection 51, make clamping hook arm 31 break away from the bayonet socket of light fitting body 1 very easily, realize that lamp holder breaks away from light fitting body.Gentle be subjected under the external force not and can rotating in order to make along the periphery of the small cylinder 3 of holder structure to circle 5, detent arranged in that the periphery of small cylinder 3 is plastic, on the internal perisporium of flexible rings 5, locating convex block is set corresponding to the detent position, structure like this, when flexible rings is set on the holder structure, locating convex block is stuck in the detent, then can not produce relatively rotating of flexible rings and lamp holder.

Certainly, above-mentioned holder structure also can be the cylindrical of an inner hollow and an end opening, and clamping hook arm extends suitable distance from cylindrical bottom portion to port openings, forms grab at the free end of clamping hook arm to holder structure internal perisporium one side; Lamp holder perisporium appropriate position in corresponding clamping hook arm position offers through hole, one pushes projection passes this through hole and is fixedly connected on the clamping hook arm, this other end of pushing projection stretches out the lamp holder periphery wall, in order to realize the sealing of lamp holder periphery wall, can be on the lamp holder periphery wall a sheathed flexible rings, on this flexible rings, form corresponding to the groove of pushing projection, when flexible rings is set on the lamp holder periphery wall, the groove of flexible rings covers just and pushes projection, thereby realize by pushing the projection of pushing of flexible rings groove, make the grab of holder structure break away from bayonet socket on the light fitting body very easily, realize the installation and the dismounting thereof of holder structure.
