Description of drawings

The light fixture riser structure schematic diagram that Fig. 1 provides for the utility model embodiment.

The specific embodiment

In order better to understand the technical solution of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.

The light fixture lifter that the utility model embodiment provides, as shown in Figure 1, comprise: be installed in fixed underpan 101 on the roof, be installed in have through wires hole on the described fixed underpan 101 wire coil shaft 110 with gear motor 102, be installed in the scroll bar 106 on the described gear motor 102, power supply is provided and control described gear motor 102 motor controller 111, be installed in the annular slot type take-up reel 108 and the bakelite cannelure that have turbine 107 on the described wire coil shaft 110 and receive rewiring plate 109.

The described gear motor 102 described worm gear 107 that is in transmission connection, described worm gear 107 is received rewiring plate 109 with described annular slot type take-up reel 108 and bakelite cannelure and is rotated, described annular slot type take-up reel 108 is provided with a plurality of cannelures, the corresponding pulley 103 of each cannelure, around volume wire sling 106 is arranged in each cannelure, described wire sling 106 connects lamp body by the pulley 103 that is arranged on described fixed underpan 101 peripheries, described bakelite cannelure is received in the rewiring plate 109 and is wound with electric wire 105, concentric is provided with copper band in the described bakelite cannelure rewiring plate 109, and described copper band can turning set on institute's take-up reel axle 110, one end of described electric wire 105 is connected described bakelite cannelure and receives on the copper band of rewiring plate 109, the centre bore that is positioned at described bakelite cannelure receipts rewiring plate 109 of described copper band, described copper band and described rewiring plate 109 are fixed together, and receive rewiring plate 109 concentrics with described bakelite cannelure, and the described dish that is positioned at described bakelite cannelure receipts rewiring plate 109, described electric wire 105 1 ends are connected electrically on the described copper band, the other end of electric wire 105 is electrically connected with lamp body through pulley 112, described carbon brush holder is fixed on the wire coil shaft 110, and be positioned at the centre bore that described bakelite cannelure is received rewiring plate 109, described copper band docks with carbon brush on the described carbon brush holder, described carbon brush one end is connected with power supply 113 by the through wires hole of electric wire through wire coil shaft 110, electric wire for described bakelite cannelure receipts rewiring plate 109 under described power supply 113 just rotates by the contact of described carbon brush and copper band is electrically connected, so that the lamp body that connects for this electric wire 105 provides power supply, on the described fixed underpan 101 motor controller 111 is installed, described motor controller 111 is connected with on gauge tap or the controller 111 and is equiped with remote control switch, power supply 113 is electrically connected by electric wire with described carbon brush in addition, and provides power supply for described motor 102.The use of this copper band and carbon brush prevents electric wire 105 because directly be connected with power supply 113, and is received rewiring plate 109 around unrest by the bakelite cannelure in rising and decline process.

The 105 folding and unfolding guarantees of lifting process power line: power supply is selected the parallel cord 105 of GB for use according to general power, and join special isolation bakelite cannelure and receive rewiring plate 109, be installed on the turbine 107, the bakelite cannelure is received in the rewiring plate 109 in electric wire 105 length of volume and described annular slot type take-up reel 108 equal in length around the wire sling of rolling up 103 to keep synchronous folding and unfolding.In order to solve electric wire 105 rotation damage problems, receive two annular copper bands of rewiring plate 109 inwalls installing at the bakelite cannelure, these two copper bands receive with the bakelite cannelure respectively that two carbon brush are connected on the carbon brush holder of rewiring plate 109 centre bores, and the bakelite cannelure receives that copper bands center on center carbon brush rotating in the rewiring plate 109 during turbine 107 operations.For the parallel soft electric wire 105 of better protection acts freely injury-free in the folding and unfolding process; on fixed underpan 101 electric wire junctions, be equiped with electric wire pulley 112 and extension spring; go out several centimeters places behind the pulley 112 of electric wire 105 by fixed underpan 101 and hang up slight pulling force extension spring or put on spring and be connected with the lamp body electric wire again, electric wire 105 can be stretched.Electric wire 105 has slight error with wire sling 103 length in the lifting running, by pulley 112 and spring fine setting electric wire 105 degrees of tightness, remains electric wire 105 degree of tightness appropriateness, to reach the purpose of protection electric wire 105.The ground wire of power supply 113 is fixed on this fixed underpan 101 and has guaranteed energising safety by wire sling 103 connection lamp bodies.Take-up reel 108 and bakelite dish 109 operation in the same way simultaneously drive wire sling 103 and soft parallel wires 105 synchronous folding and unfolding lifting lamp bodies when the 106 transmission turbines 107 of worm screw on the motor 102.

This light fixture lifter can constantly be realized the automatic lifting of lamp body, and because a motor 102 is set on fixed underpan 101 and take-up reel 108 just can be realized the lamp body automatic lifting, will save cost than a plurality of motors and take-up reel are set on fixed underpan; And by installing take-up reel on fixed disk, than directly the spiral take-up reel of installing and annular take-up reel are synchronously firm more on motor, and volume is little, the wider Crystal lamp of the full scope of application of function, lamp affixed to the ceiling, pendent lamp, Metal halogen lamp or the like.And carry out folding and unfolding lifting rope balance, stable, synchronously more than a plurality of motors.

Light fixture safety in the lamp body is by the auto-lock function guarantee: lamp body is big, install auto-lock function when weight is big additional, opens self-locking when the decline light fixture in advance, the lamp body of the finishing the work back self-locking that resets of rising.When motor 102 stops operating, because the effect of worm screw 106 and turbine 107, block motionlessly, have auto-lock function, when lifting outage in service, the decelerator self-locking.Lamp body no longer moves, with protection lamp body and personal security.Can by power control switch or remote controller control lamp body automatically about, lifting, the switch light fixture need not professional's operation, gives to clean maintenance and change light source to bring great convenience, and reduces the maintenance and repair cost.

More than a kind of light fixture lifter that the utility model embodiment is provided be described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, part in specific embodiments and applications all can change, in sum, this description should not be construed as restriction of the present utility model.
