Abstract
The utility model relates to a movable, lifting, and extensible lamp stand, which is characterized in that a nut is fixedly arranged on an angle end of the top of the lamp stand which is composed of a frame. A connecting plate whose upper part is provided with a motor and the angle end is provided with a screw rod which is meshed with the nut of the lamp stand is arranged on the upper part of the lamp stand. The motor drives the screw rod to rotate by a sprocket. The screw rod is meshed with the nut to cause the lamp stand to be lifted. The movable, lifting, and extensible lamp stand which has the advantages of simple structure, low cost, reliable use, convenient operation, capability of the simultaneous realization of moving and lifting of the lamp stand, variable lamp arrangement area, and accurate positioning is a replacing product for a present stage lamp stand.
Description
The utility model relates to light of stage equipment, especially a kind of mobile lifting expandable type lamp bracket.
The employed various dedicated lamp of stage generally will be contained on the lamp bracket (also claiming the lantern suspension bracket) at present.According to the requirement of scenery rendering effect, lamp bracket will need to move or lifting at any time.What existing stage lamp bracket adopted when mobile or lifting is that stay cord or handcraft realize moving or lifting.Because the structure of existing lamp bracket is not quite reasonable, make lamp bracket exist and move the difficult problem that can not realize simultaneously with lifting, and lamp bracket location inaccuracy, utilization benefit is low.Especially when requiring large tracts of land cloth lamp, need a plurality of lamp brackets to arrange simultaneously, it is big to take up room, and increases cost, also dangerous during use.
The purpose of this utility model is to overcome the deficiency in the prior art, provides a kind of can the realization simultaneously to move and lifting cloth lamp variable area, the reliable mobile lifting expandable type lamp bracket of accurate positioning.
The purpose of this utility model is achieved in that
The lamp bracket top corner end that constitutes at framework of the present utility model is fixed with screw, lamp bracket top has one the connecting plate that motor and its angle end are equipped with the screw mandrel that is meshed with the lamp bracket screw is housed on it, motor rotates by the chain wheel drive screw mandrel, and screw mandrel engagement screw makes the lamp bracket lifting.
A side lamp frame respectively is equipped with by hinge in lamp bracket of the present utility model both sides.
The bloated wheel of the chain of tightening sprocket wheel also is housed on the connecting plate of the present utility model.
Also be fixed with the handcraft of walking on the track that can install above it, driven dolly on the connecting plate of the present utility model.
Advantage and the good effect that the utlity model has are:
1. rotate by the chain wheel drive screw mandrel by the motor on the connecting plate, screw mandrel engagement screw is realized the lamp bracket lifting; With advancing, move lamp bracket by manual dolly, realized moving and carrying out lifting time of lamp bracket, and accurate positioning is reliable, the sport efficiency height.
2. two side lamp framves are housed in the lamp bracket both sides, and when launching lamp bracket, maximum cloth lamp area can increase about twice, and the lamp bracket constancy of volume, and it is little to take up room.
3. simple in structure, cost is low, uses reliably, and is easy to operate, is the substitute products of present stage lamp bracket.

Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
The top corner end of the lamp bracket 9 that framework constitutes is fixed with screw 12, and this screw can be welded on the lamp bracket, also can make on lamp bracket.Side lamp frame 13 is equipped with by hinge 14 in the both sides of lamp bracket, and lamp bracket generally is to make cuboid, and side lamp frame area promptly has screw (totally 4 screws) four jiaos of lamp brackets greater than the area of lamp bracket front-side frame, and dotted line is depicted as the folding state of side lamp frame in Fig. 4.There is a plate 5 the lamp bracket top, and the screw mandrel 11 of engagement screw all is equipped with in the corresponding lamp bracket screw of this connecting plate angle end position, and each screw mandrel head end is fixed with driven sprocket 4.One motor 7 is housed in the middle of the connecting plate, and this motor drives the drive sprocket 6 that is contained on the connecting plate by reduction gearing 16 engagements, and drive sprocket drives driven sprocket by chain 8, and the bloated wheel 15 of tightening chain also is housed on connecting plate.Structure that connects and installation are referring to Fig. 4, Fig. 5, Fig. 6.Track 1 also is equipped with in the top of connecting plate, is lifted with manual dolly 2 and driven dolly 10 on the track, and manually dolly and driven dolly all are packed on the connecting plate.Manually pull chain 3 on the dolly, pull chain by tractive manual dolly is walked in orbit, thereby affect lamp bracket to move.Two on track is arranged in the present embodiment, be the I-shaped die, manually dolly is one, and two in driven dolly is the triangle state and is contained on the connecting plate.
The utility model using method is very simple, and lamp bracket moves through tractive and pulls the chain realization, and lifting then makes the screw mandrel rotation by the motor-driven sprocket wheel, and screw mandrel engagement screw is realized.The lifting of lamp bracket and mobile steadily reliable, accurate positioning, the side lamp frame can launch with the lamp situation according to stage or be folding, changes cloth lamp area.
