The lamp-mounting fixing device comprises a screw rod and a pressing block for supporting, wherein the screw rod is erected on the outer side of a tank hole of the bracket, the lower part of the screw rod is provided with a driving device capable of driving the screw rod to rotate, one end of the pressing block with a gap is sheathed and inserted on the screw rod and forms a slide fit with the screw rod, the other end is radially extended out of the screw rod and the gap end of the pressing block is provided with a screw rod spring sheet which is butted on screw teeth of the screw rod and is matched with the screw teeth in a rotating way through screw threads. Through the design, so long as the pressing block is pulled down, and then a knob is screwed, the utility model can accomplish the support and mounting of a lamp on a ceiling so that the lamp has the advantage of simple and easy assembly and disassembly on an installing hole of the ceiling; the lamp-mounting fixing device has the advantages of simple and fast operation, firm and reliable insertion and support to the lamp and high safety and can be used on a plurality of different lamps.

Description

The lamp installation fixator

Technical field

The utility model relates to the member of light fixture, particularly assists the annex of light fixture assembly in the ceiling installing hole.

Background technology

At present, in order to allow the light fixture assembly on the installing hole of ceiling, conventional art adopts shell fragment or torsion spring is installed on lamp bracket, utilize elastic force clamping ceiling, light fixture is fixedly attached in the installing hole, and such mounting means is simple, easy operating, but that defective is security is low, reliably poor, elastic force clamps has randomness, and light fixture has getting loose at any time, the danger under weighing down.The structure that the technical scheme that also has adopts screw to cooperate with the spiral briquetting, though it is very firm after installing, mounting or dismounting all need to use instrument set screw such as screwdriver, waste time and energy, mounting or dismounting efficient is extremely low, uses inconvenient.

The utility model content

The purpose of this utility model is the weak point that overcomes conventional art, propose a kind of on the ceiling installing hole mounting or dismounting very convenient, fast, and firm, the safe and reliable lamp installation fixator of assembly supporting.

The purpose of this utility model is achieved by the following technical solution: the lamp installation fixator, be loaded on lamp bracket or the housing, include the briquetting of screw rod and supporting usefulness, screw rod is erected in the slotted eye outside of support, the transmission device that can drive its rotation is equipped with in the screw rod bottom, the end cover that briquetting has a breach inserts on the screw rod and forms with it and is slidingly matched, the other end then extends radially out outside the screw rod, and the breach end of briquetting is provided with a screw rod shell fragment, and the screw rod shell fragment props up the thread of screw rod and forms screw thread rotation with it and cooperates.Further, be the convenient operation of regulating, transmission device is made of knob and travelling gear, and travelling gear is anchored on screw rod bottom and interlock with it, and knob is located at the inboard of support slotted eye, and the internal tooth of knob meshes with travelling gear.For make briquetting contact with ceiling steadily, reliable, briquetting is " eight " font for two of symmetry, they are connected the common and screw rod socket in back mutually and are slidingly matched.And the both sides, bottom of support slotted eye are provided with can change the guide vane that briquetting points to when briquetting moves down.

Such structure, have tangible advantage: briquetting and screw rod are slidingly matched, make when installing and directly to contact with the ceiling of installing hole stretching under the briquetting, making the screw rod shell fragment compress thread by the rotation knob again is out of shape, thereby briquetting is further compressed, locking, the whole erection operating process is very easy, fast, and " eight " font of briquetting and guide vane etc. are all guaranteed the tight of briquetting and ceiling surface, steadily contact, be difficult for getting loose, skew, such fixator can supporting various forms, the light fixture of structure uses, install both convenient and swift, safe and reliable again, also balance between aesthetics.

The specific embodiment

Referring to Fig. 1-Fig. 5, the lamp installation fixator of present embodiment is mainly by support 1, screw rod 2, symmetry is connected a pair of briquetting 3 that is " eight " font, the knob 4 that has internal gear, travelling gear 5 formations such as grade, support 1 central authorities have slotted eye 11, both sides, slotted eye 11 bottom are provided with wedge shape guide vane 12, screw rod 2 is erected in the outside of support slotted eye 11, screw rod 2 is to adopt rotary shaft to install, screw rod 2 bottoms and travelling gear 5 coaxial being connected, the position of travelling gear 5 then strides across slotted eye 11, with the internal tooth engaged transmission of the knob 4 of support 1 inboard, like this, as long as turning knob 4, just can rotate by travelling gear 5 drive screws 2, they form the rotation drive connection mutually.Briquetting 3 is a pair of of symmetry, one end of each briquetting 3 has breach 31 and this end cover and inserts on the screw rod 2 and form axis holes with screw rod 2 and be slidingly matched, the other end of briquetting 3 then extends radially out outside the screw rod, the breach end of two briquettings 3 is connected jointly back mutually and screw rod 2 formation are slidingly matched, integral body is " eight " font, wherein be provided with a screw rod shell fragment 6 in the breach 31 of a briquetting 3, screw rod shell fragment 6 props up the thread of screw rod 2 and forms screw thread rotation with it and cooperates.

Operation principle: when fixator does not use, two briquettings 3 are in screw rod 2 tops, two briquettings 3 open under the active force of torsion spring, smooth support 1 outside is (as Fig. 1, shown in Figure 2), when fixator install to clamp (as Fig. 3, shown in Figure 4) if manual from support 1 inboard with two briquettings 3 to pressing down, because briquetting 3 itself and screw rod 2 are for being slidingly matched, screw rod shell fragment 6 is again forward drop-down, so briquetting 3 moves down required active force and not quite just can finish, in briquetting 3 folding processes, can be subjected to the guiding squeezing action of guide vane 12 midway and close up in opposite directions, outwards perk (as shown in Figure 3), when the lower surface of briquetting 3 contacts the ceiling of lamp installation hole periphery, screw knob 4 from support 1 inboard again, knob 4 drives screw rod 2 rotations, because forming feed screw nut's formula with screw rod 2, screw rod shell fragment 6 cooperates, screw rod shell fragment 6 is connected with briquetting 3 again, driven again at the effect lower lock block 3 of screw rod shell fragment 6 and to be moved down, thereby make briquetting 3 compress ceiling, because screw rod shell fragment 6 has the backward hold effect, the situation lower lock block 3 that knob 4 does not rotate does not move on can not rebounding automatically.Fixing holder on the light fixture generally has at least two, and behind fastening one side, the same manner screws another side again, thus make whole light fixture safety, fast, assembly (as shown in Figure 5) on ceiling securely.

Certainly, only enumerated a kind of preferred implementation here, the protection category that other is equal to, structure roughly the same all should belong to this patent repeats no more here.
