Description

The adjustable fluorescent lighting fixture of a kind of light angle

Technical field

The utility model relates to a kind of fluorescent lighting fixture, relates in particular to the adjustable fluorescent lighting fixture of a kind of light angle.

Background technology

Existing fluorescent lighting fixture is with screw to be fixedlyed connected with ceiling or other objects in the room in the top of fluorescent lighting fixture support body mostly, thereby whole fluorescent lighting fixture is installed in the room.This fluorescent lighting fixture is generally offered installing hole at the top of support body, during actual installation, needs to pass this installing hole and fixing bracket body with screw earlier, again by last fluorescent-lamp tube.Because of screw directly is fixed on support body on the ceiling, support body is in a single day fixing just can not to be moved or rotate at all again, thereby can not regulate light angle and scope according to actual needs, is unsuitable for practical application.Therefore, the adjustable fluorescent lighting fixture of some light angles is invented, and is that the Chinese utility model patent " a kind of fluorescent lighting fixture " of ZL02250165.7 (publication number is CN2589815Y) discloses a kind of technical scheme as the patent No..This fluorescent lighting fixture, include support body, be arranged on the installing tache that is " ∏ " shape at support body top and be the holder of " ∏ " shape and the steering base that sliding seat is formed, wherein, holder directly is fixed on the ceiling, sliding seat is fixing with installing tache by screw, and sliding seat and holder match and be connected within the holder by the bearing pin on the sliding seat is rotating, regulate the angle of support body by relatively rotating between sliding seat and the holder, thereby reach the purpose of regulating light angle.But this fluorescent lighting fixture, the weight of its whole fluorescent lighting fixture support body is supported on the bearing pin on this sliding seat by installing tache, in actual use, slight bearing pin is very easy to fracture and causes the accident of support body to drop, actual production adds man-hour, these accessories often adopt one injection molded, just easier meeting accident, safety inadequately; And when actual installation, be earlier holder to be fixed on the ceiling, then the bearing pin of sliding seat being snapped in the axis hole of holder, the card of bearing pin is established also relatively effort, causes the damage of holder fracture or bearing pin itself easily; In addition, the sliding seat outside of this fluorescent lighting fixture is provided with convex tendon, and the holder inboard is provided with the blend stop of cooperation, by making convex tendon and cooperating of blend stop sliding seat relative fixed seat location, when practical adjustments,, and make convex tendon move by side to opposite side from one of blend stop because of needs overcome the active force of the mutual compressing of convex tendon and blend stop, be difficult for rotating, and relatively require great effort, and when convex tendon withstands on the top of blend stop, at this moment, the gap maximum of holder and sliding seat, the slippage from the holder of sliding seat upper pin is come out, and like this, support body can fall down again, abnormally dangerous, there is potential safety hazard in practical application.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of adjustable fluorescent lighting fixture of light angle convenient, that cooperation is firm, safe and reliable of installing is provided at above-mentioned prior art present situation, it can regulate the suspension angles of support body according to the actual illumination needs, thereby is more suitable for practical application.

The utility model solves the problems of the technologies described above the technical scheme of being taked: the adjustable fluorescent lighting fixture of this light angle, include support body and holder, it is characterized in that: described support body top is provided with installing plate, the end of this installing plate is exposed at outside the support body and this end is extended with kink downwards, and described holder is the L type, and the lateral part of this L type holder is connected by bolted with the kink of this installing plate end.

When need regulating light angle, as long as unscrew that bolt between mounting plate and the holder, installing plate can rotate by the relative fixed seat, support body and installing plate is turned to suitable position, again mounting plate and holder; When actual installation, the vertical part of this L type fixed head is direct and bodies of wall generations such as ceiling or furred ceiling are fixing, and holder is fixed on the body of wall.

In daily life, people are fluorescent lighting fixture to be suspended on a jiao of ceiling mostly, therefore, the adjustable range of light angle is generally within 90 degree, rotational angle for the restriction support body, can be that central point offers a mounting hole with described bolt on the lateral part of described L type holder, and side direction is protruding with a projection that matches on the kink of described installing plate, this projection is with regard in the spacing mounting hole on described holder, thereby make support body when adjusting angle, can only be in the angular range of this mounting hole movable, avoid that the support body rotational angle is excessive to bump with holder even body of wall.

The set-up mode of described installing plate at the support body top can adopt existing various technology, but for ease of actual installation, to guarantee that simultaneously installing plate and the firm of support body are connected, avoid causing the accident of support body to drop, described support body top can be fixed with a substrate, and described installing plate by with the fixing and indirect top that is fixed on support body of this substrate, and, described base plate bottom is extended with L type trip downwards, and described support body top has the dovetail groove that is complementary, the L type trip of described base plate bottom just is embedded among this dovetail groove, thereby makes substrate lift support by this trip.

For prevent that substrate from arbitrarily sliding among the dovetail groove at support body top, can pass the central screw of described support body top and substrate by a bolt, make both fixing together, after substrate is adjusted relative position with support body, just can be fixed on the support body top like this.

Be embedded among the dovetail groove at support body top for ease of the L type trip of base plate bottom, described support body can include central support body and the lid that is fixed on its two ends, described dovetail groove just is arranged on the top of whole central support body longitudinally, during actual installation, the substrate that has connected with installing plate, slip into the dovetail groove at its top from the two ends of central support body, and then lid is fixed on the two ends of central support body, like this, substrate is just spacing within dovetail groove by lid, and substrate can manual slip be adjusted its position at the support body top, the balance of assurance fluorescent lighting fixture.

Compared with prior art, advantage of the present utility model is: the installing plate by being arranged on the support body top be arranged on body of wall on the cooperating of holder, as long as unscrew bolt, but installing plate relative fixed seat is rotated, thereby support body is rotated relative to body of wall, the suspension angles of realization support body can be regulated at any time according to the actual illumination needs, angle orientation is good, very practical, and holder is connected by bolted with installing plate, very convenient during actual installation, and cooperation is solid and reliable between the parts, prevents that the accident of support body from dropping, and has guaranteed safety; The setting of mounting hole is rotated support body on the lateral part of L type holder in certain angle, has prevented that support body and holder even body of wall from bumping and damage; Simultaneously, the utility model is simple in structure, is easy to production and processing, and it is convenient, firm to install.
