The specific embodiment
The invention provides a kind of bulb loosening-prevention structure, this structure is arranged at socket support plate, lamp socket also is being installed on socket support plate and is being plugged in bulb on lamp socket, wherein, this bulb loosening-prevention structure comprises: the lamp head to lamp socket and bulb applies the bulb pressing plate of firm pressure and the slide groove portion that is fixed in socket support plate; The bulb pressing plate comprises: moved end section, moved end section and marginal lug boss, the moved end section of bulb pressing plate is movably connected on socket support plate, the lug boss of bulb pressing plate is crossed the lamp head of lamp socket and bulb and is contacted with lamp head is adaptive, and the moved end section of bulb pressing plate slides and is arranged at slide groove portion.
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in further detail.
As shown in Figures 1 to 4, the socket support plate 100 of bulb loosening-prevention structure 10 is a square sheet material, and this sheet material can be metallic plate, also can be high-strength rubber or plastic plate, and its profile structure can for circular or other shapes, not done restriction at this yet; Central region in socket support plate 100 is equipped with lamp socket 220, and the lamp head 210 of bulb 200 is inserted and is linked into 220 li of lamp sockets, and the conductive electrode of lamp head 210 is electrically connected to (not shown) with the conductive electrode formation of lamp socket 220.The bulb pressing plate 300 of bulb loosening-prevention structure is a bonding jumper, and its material is the silicon steel with certain rigidity, or other rigid metals.Bulb pressing plate 300 comprises quiet end 310, moved end section 320 and falls between a lug boss 340 in addition, and the length of lug boss 340 is slightly larger than the width of lamp socket 220, and quiet end 310 and moved end section 320 parallel with socket support plate 100 and depart from lug boss 340 and point to setting; Lug boss 340 is fully firmly contacted with the lamp head of bulb 200.In the present embodiment, when bulb pressing plate 300 profile structures were " several " font, quiet end 310 and moved end section 320 paralleled with lug boss 340 and depart from lug boss 340 and point to setting; At this moment, be respectively equipped with support edge 350 between lug boss 340 and quiet end 310, moved end section 320, the height of support edge 350 is suitable with the height of lamp socket, can make like this lamp head 210 of the lug boss 340 better firm bulbs 200 of bulb pressing plate 300; The quiet end 310 of bulb pressing plate 300 is movably connected on socket support plate 100 by screw 130 these securing members, makes the quiet end 310 of bulb pressing plate 300 to rotate take screw 130 as rotating shaft.
Be provided with the slide groove portion 110 be used to the moved end section 320 that holds bulb pressing plate 300 on socket support plate 100, this slide groove portion 110 forms clamping with moved end section 320, and the moved end section 320 of bulb pressing plate 300 can be with respect to slide groove portion 110 relative slidings.In the present embodiment, slide groove portion 110 is a deep-slotted chip breaker, and its center of circle refers to the quiet end 310 of bulb pressing plate 300, and this deep-slotted chip breaker 110 is positioned on the longitudinal central axis line of lamp socket 220 near lamp socket 220 1 ends and screw 130.Like this, in the time the lamp head of bulb and lamp socket need to being formed firm grafting, only need the moved end section of bulb pressing plate is rotated around screw, its moved end section is slided to an end near lamp socket 220 away from an end of lamp socket 220 along deep-slotted chip breaker 110 by deep-slotted chip breaker 110; Like this, the lug boss 340 of bulb pressing plate 300 will form the firm shape that presses with the lamp head 210 of bulb 200, reaches and avoids the lamp head of bulb to loose from lamp socket; Otherwise, the lamp head of bulb can be loosed from lamp socket.
For ease of holding the moved end section 320 of bulb pressing plate 300, be provided with a wide oral area 120 at deep-slotted chip breaker 110 away from an end of lamp socket 220, the size of this wide oral area 120, profile structure are suitable with size, the profile structure of moved end section 320; In the present embodiment, its profile is configured to square.
For moved end section 320 deep-slotted chip breaker 110 slips relatively after being vibrated that prevent bulb pressing plate 300, and the lamp head 210 that causes bulb 200 occurring looses from lamp socket 220; The present invention has done again further improvement, is provided with a spacing fixed part 121 in slide groove portion 110 near lamp socket 220 1 ends, and this spacing fixed part 121 is a recess away from lamp socket 220, and the degree of depth of recess is slightly larger than the thickness of bulb pressing plate 300.Like this, when 210 one-tenth of the lamp heads of bulb pressing plate 300 and bulb 200 firmly press shape, by means of the elastic-restoring force of bulb pressing plate 300 materials, the moved end section 320 of bulb pressing plate 300 is snapped in spacing fixed part 121, prevent that the moved end section 320 of bulb pressing plate 300 from sliding along deep-slotted chip breaker 110 after being vibrated.
For more firm being plugged on lamp socket 220 of lamp head 210 that makes bulb 200, the present invention has done further technological improvement, lug boss at bulb pressing plate 300 is provided with a holding part 330 for adaptive accommodating bulb 200 lamp heads 210, its size, profile structure are constructed suitable with size, the profile of the lamp head 210 of bulb 200, as shown in Figure 4, thus reach the more firm effect of pressing lamp head 210.
The present invention also provides a kind of light fixture that uses above-mentioned bulb loosening-prevention structure, and as shown in Figure 5, this light fixture comprises lamp body 400, and the above-mentioned bulb loosening-prevention structure 10 that is placed in the lamp holder inner chamber.
Should be understood that, above-mentioned statement for preferred embodiment of the present invention is comparatively detailed, can not therefore think the restriction to scope of patent protection of the present invention, and scope of patent protection of the present invention should be as the criterion with claims.
