The specific embodiment

See also shown in the accompanying drawing, the utility model will be further described.

When stereogram and Fig. 2 the utility model rise when sagging as Fig. 1 the utility model shown in the stereogram, the utility model provides a kind of liftable pendent lamp, comprise elevating mechanism 15 and lifting rope 14, elevating mechanism 15 is made of a reel and left and right case, the reel nationality helps an axis 1 that is fixed on the left and right case to rotate, lifting rope 14 is on reel, and lifting rope 14 lower ends connect light fixture 28, and axis 1 is fixed on left and right case by nut 5 and packing ring 12.Lifting rope 14 passes the power line with retractility 16 (as shown in Figure 3) of a coiling, and lifting rope 14 is subjected to the reel scrolling and upper and lower, and 16 of this power lines shrink or prolong.

As Fig. 4, Fig. 5, Fig. 6, Fig. 7 and shown in Figure 11, an axis hole 2 is arranged in the middle of the right case, the B end of axis 1 is fixed in axis hole 2; In the middle of the left side case 7 axis hole 17 is arranged also, the D end of axis 1 is fixed in the axis hole 17 of left case 7.Hexagonal (hexagon)nut 23 on the ratchet-gear wheel imbeds in the inboard recessed hexagonal (hexagon)nut 4.Right case is provided with screw 10, is complementary with the screw 13 of left case 7, with closed about reel.Right case is provided with the extension lifting hole(eyelet) 11 of claw type, will hang to hang 26, in like manner, also is provided with the extension lifting hole(eyelet) of claw type on the left case 7.

As Fig. 8, Fig. 9, shown in Figure 10, the left end of described reel is a recess, one wind spring buries in this recess, one bayonet socket 20 is arranged on the recess limit, wind spring one end sticks into the bayonet socket 20 on the recess limit, the other end sticks on the axis that passes reel centre bore 18 in the wind spring bayonet socket 22, when reel rotates, and wind spring accumulation of energy or release can; The other end of reel also has a recess, and this recess inwall has ratchet 19, and another ratchet-gear wheel imbeds in this recess.Reel is provided with rope blocking ring 27, prevents the slip of restricting.

As shown in Figure 12 and Figure 13, on one side described ratchet-gear wheel has protruding hexagonal (hexagon)nut 23, this hexagonal (hexagon)nut 23 imbeds in the inboard recessed hexagonal (hexagon)nut 4 of right case.The ratchet number of reel right-hand member recess inwall is two times of ratchet 24 on the ratchet-gear wheel, and all is that plastics are made that ratchet 24 is the rubber-like plates on the ratchet-gear wheel.

As shown in figure 14, overcoat 8 has internal thread 25, and copper sheathing 6 has external screw thread, and the internal thread 25 of overcoat interconnects with the external screw thread of copper sheathing 6.

Wind spring of the present utility model, releasing after its maximum accumulation of energy (being that rolling-in is to extreme position) can strength, can not mention pendent lamp, promptly can not drive reel and rotate, the pendent lamp that must hold in the palm, wind spring release can the time could drive the reel rotation.

Ratchet-gear wheel of the present utility model, because be a kind of rubber-like slice plastic sheet, so the ratchet engagement on itself and the reel right-hand member recess inwall is not very tight, during with external force backward rotation reel, reel also can rotate.

During operation, if pendent lamp is in eminence, the wind spring of reel left end is in and releases the energy state at this moment, and promptly wind spring is lax, and the ratchet of reel right-hand member inwall and ratchet-gear wheel engagement are blocked, and pendent lamp can not fall; The pendent lamp position need be reduced, then grasp lampshade and spur downwards, lifting rope drives the ratchet sheet and rotates, and the lifting rope 14 on reel prolongs downwards, simultaneously, and the progressively rolling-in accumulation of energy of the wind spring of reel left end.

If pendent lamp need be raised to eminence, the lampshade that then holds in the palm, the wind spring of reel left end are released energy, and the scrolling reel rotates, and makes on the lifting rope 14 and moves, and hand is removed lampshade, and pendent lamp just is parked in this position.

Bulb of the present utility model is connected with power line 16, available commercially available various light bulb holders, and bulb and lampshade can be changed.
