Abstract
The utility model relates to a base with hoisting or lowering lamp holder, which is composed of a fixed portion and a movable lamp holder, wherein, the movable lamp holder can be inserted into the fixed portion and is clamped and fixed in the fixed portion. The utility model is characterized in that the walls of an inner cavity of a fixed seat (1) are symmetrically provided with crab claw type linkage springs, the upper part of the movable lamp holder (3) is provided with a rope (5), and the rope is penetrated through the fixed seat (1) and is hung down to the ground through pulley wheels. When the rope is pulled, the movable lamp holder can separated from the fixed portion along with the downward release of the rope, and then, the self of the lamp holder is not connected with a power supply. When the movable lamp holder is dropped downwards to the point near the ground, people can safely and conveniently change a light bulb.
Description
The utility model belongs to the suspension or the jockey of lighting device, particularly relates to the liftable lamp socket of lamp holder.
Be installed in station, harbour, square, highway and factory floor lighting, mostly be positioned at overhead the place of five to tens meters of height, need ascend a height or use the lifting facility just can reach when changing the bulb that damages, and often want hot line job, charged for replacement bulb on such height is dangerous inconvenient again to installation personnel.
The purpose of this utility model provides a kind of lamp socket that has the liftable lamp holder, and it need not ascend a height people and just can more change the bulb on uncharged lamp holder, or else needs the special lamp holder of ascending a height and more changing the bulb after promptly installing for the first time.
The purpose of this utility model realizes by the following technical solutions: lamp socket is made up of standing part and movable lamp holder two parts, standing part is fixedly mounted on higher lighting position and connects power supply, and movable lamp holder can insert in the standing part from bottom to top and be clamped and be fixed therein.There is a rope to pass standing part on the top of movable lamp holder and falls to ground downwards, can be connected a lower fixed position through pulley.When unclamping rope, movable lamp holder can break away from standing part along with transferring of rope, and lamp holder when breaking away from standing part lamp holder itself do not connect with power supply.When movable lamp holder drops to liftoffly more nearby the time downwards, people can be safely, more change the bulb easily.
Be arranged with two or more crab claw type interlock springs on the standing part internal chamber wall, have rotating shaft to connect between the last lower claw, when movable lamp holder inserted, dewclaw was supportted outward, and lower claw promptly inwardly clamps, but makes movable lamp holder clamping therebetween.
The utlity model has safe in utilizationly, convenient, be applicable to that people need not ascend a height just can on uncharged lamp holder, more change the bulb.
The utility model is described in further detail below in conjunction with accompanying drawing and as embodiment:
Fig. 1 is the vertical section structure schematic diagram of the utility model embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: the 1st, holder, the 2nd, fixing following (lid), the 3rd, and movable body, the 4th, cover, the 5th on the lamp holder, rope, the 6th, fixed pulley, the 7th, buffer spring, the 8th, spring dewclaw, the 9th, lower claw (hook), the 10th, turning cylinder, the 11st, conduit, the 12nd, socket, the 13rd, tube face (balance weight body), the 14th, power lead, the 15th connects cable address hook, the 16th, lamp holder circuit closer, the 17th, the horizontal rib of body.
Shown in Fig. 1, standing part is formed by holder 1 and fixing following 2 fastening, be installed with a fixed pulley 6, spring dewclaw 8 and lower claw 9 on the inner chamber top of holder 1, movable body 3 can pass 9 of the spring dewclaw 8 of fixing following 2 insertion holder 1 and lower claws; Be provided with the horizontal rib 17 of a circle projection at body 3 middle parts, when a pair of lower claw 9 is closed, can tangle horizontal rib 17.Lamp holder divides two joints up and down again, top is a movable cover 4 of going up, the bottom is a body 3, on movable body 3, lean out a conduit 11, cover 4 is enclosed within outside the conduit 11 on the lamp holder, 11 liang of tops of conduit are bigger, have a rope 5 to pass at an upper portion thereof in conduit 11, and this rope 5 passes holder 1 and hangs down through pulley 6.
In Fig. 2, power line 14 is connected in connecing on the cable address hook 15 of holder 1, has lamp holder circuit closer 16 at the horizontal rib 17 of movable body, and it fuses with lead 14 and socket 12, at dewclaw 8 with connect rotating shaft 10 is arranged between the cable address hook 15.When inserting lamp holder, cap 4 connects dewclaw 8 outer supports cable address hook 15 and promptly inwardly clamps on the lamp holder, contacts with lamp holder circuit closer 16, thereby power supply is connected with socket 12.And lamp holder 3 is when breaking away from holders 1, and lamp holder 3 does not connect with power supply itself.
Using method: the bulb in being installed in this lamp socket damages when needing to change, the people stands in ground pulling rope 5, moving to pulley 6 on the conduit 11 of movable lamp holder ends, spring dewclaw 8 enters eel-like figure part body 3 places of movable lamp holder and loses outside support power at this moment, thereby make lower claw 9 lose clamping force, form and open shape; Unclamp and transfer rope 5, movable body 3 begins to glide, because stopping of spring dewclaw 8, cover 4 breaks away from body 3 and the lamp holder, after body 3 skids off spring lower claw 9 downwards, cover 4 also glides with the downslide of conduit 11 on the movable lamp holder, strut power with 4 pairs of spring dewclaws 8 of cover on the right lamp holder this moment, and lower claw 9 is inwardly closed, but because of the resistance of the horizontal ridge that can not hang, last movable lamp holder becomes flexible with rope 5, reduces to replaceable bulb behind the ground.After finishing changing bulb, with rope 5 lamp holder 3 is pulled on, when lower claw to spring 8 and 9 worked simultaneously, movable body 3 was hung the jail automatically in holder 1 again, and power supply and bulb UNICOM stop drag rope 5, then rope 5 is folded be placed on lock in the box standby.
