Description

Stage Computer lamp with improvement reflecting mechanism

The utility model relates to a kind of stage Computer lamp.

Present being seen stage projecting lamp pattern is quite a lot of, the principle of using is then roughly the same, it has a shell block, be provided with light source, pattern rotating disk and light lens in the shell block, the light that it goes out light emitted sees through the pattern rotating disk, and transmits pattern by light lens, cooperates rotatable reflecting mechanism, out the shadow that rotation changes and can be, enrich the diverse visual effect of stage.

Cooperate and consult Fig. 7, shown in Figure 8, common stage Computer lamp 6, in its shell block 60 light source is set, the pattern rotating disk, the light that light source is launched sees through the pattern rotating disk and can be projected to reflecting mechanism 7 via light lens 61, again via the reflection of reflecting mechanism 7, and can get bright and new beautiful and diverse shadow projection, this reflecting mechanism 7 is to be arranged in the installment area 62 of shell block 60, the axle 701 of its motor 70 is passed by swash plate 63 places, and set firmly a turnover frame 71 in axle 701 ends, turnover frame 71 other sides are provided with the motor 72 of another rotary power, circular reflecting drum 74 is inserted the turning point of turnover frame 71, and, axle 721 ends of motor 72 are fixedly arranged on reflecting drum 74 inner bottom surfaces, again, reflecting drum 74 side faces are provided with tubular speculum 741, arc groove 64 is set on the swash plate 63 can be established by passing to connect in the shell block 60 for the electric wire 73 of motor 72, the rotation that motor 70 starts, its axle 701 can be considered the rotation of X-axis, on the arc groove 64 of swash plate 63, rotate a suitable angle and can drive turnover frame 71, again, the startup rotation of another motor 72, its axle 721 can be considered Y direction rotates, and does 360 degree rotations and can drive reflecting drum 74, therefore, light by light lens 61 wear penetrate after, but mat is beaten on the tubular speculum 741 of reflecting drum 74, and by motor 70,72 rotation, and can present the multiple three-dimensional shadow that changes.

Though this reflecting mechanism 7 has the variation design of three-dimensional axially rotation, on reality was used, still there are the following problems:

1, the X-axis rotation of motor 70 axles 701 on swash plate 63 wears because of being subject to electric wire 73, and the restriction of arc groove 64 radians, and can't make the effect that wholecircle rotates, wherein, because the disalignment of motor 70,72 to, and be the X axis rotation that avoids motor 70, cause being entangled with that electric wire 73 rotates, so, offer arc groove 64 on the swash plate 63 of this reflecting mechanism 7, therefore, the rotation of motor 70 is forward and reverse intermittent rotations that are special angle, and can't make wholecircle and rotatablely move, and cause the effect of shadow in the solid space to be had a greatly reduced quality.

2, the axle 701 of motor 70 rotation drives forward and reverse intermittent rotation of turnover frame 71, often causes electric wire 73 and 64 frictions of arc groove, easily causes electric wire 73 wearing and tearing and the situation that produces short circuit or open circuit.

3, the motor 72 of drive reflecting drum 74 rotations is arranged on the turnover frame 71, causes the rotary load of motor 70 axles 701 to increase, and reduces tripping force easily, and easily cause the motor reduction in 70 service lifes.

Therefore, there is the power consume really in known reflecting mechanism, and can't reach the preferable three-dimensional effect of shadow that changes, and more makes the effect of stage Computer lamp be difficult to represent fully.

The purpose of this utility model provides a kind of stage Computer lamp with improvement reflecting mechanism, it is to utilize two motors to have the effect of coaxial transmitting rotary power, make fixed support and reflecting drum, all can present wholecircle Zhou Xuanzhuan, the wholecircle drop shadow effect that makes the shadow of projection have X-axis and Y-axis, and the load of two motors separates and is independent separately, and can avoid the excessive weight of a motor load to cause damage.

The purpose of this utility model is achieved in that a kind of stage Computer lamp with improvement reflecting mechanism, wherein, forms installment area in the shell block of stage Computer lamp, and reflecting mechanism is arranged on the swash plate of installment area, its special being:

The power set of reflecting mechanism have two motors arranged side by side, two motors are arranged on the location-plate, on one motor spindle axle center is set, driven gear is pivoted on the axle center, the driven gear end face sets firmly fixed support, the axle center passes swash plate and fixed support and front end and sets firmly pinion stand, the pinion stand end face sets firmly bevel gear, the one pivot reflecting drum that is pivoted, and pivot is arranged on the fixed support, and the reflecting drum side face is provided with the tubular speculum, the reflecting drum two ends are provided with bevel gear, the engagement of the rodent part of set bevel gear is provided with travelling gear on another motor spindle arranged side by side, winding flute profile belt on travelling gear and the driven gear on the rodent part of reflecting drum one side bevel gear and the pinion stand.

Described location-plate one side forms flap, and the detecting plate is set on the flap, and detecting plate one end is provided with the infrared ray breaker, and tablet is set on described axle center, and the tablet periphery forms breach.

Owing to adopt such scheme: have and increase the service life, and the projection that can effectively promote the stage shadow changes efficient, have more variational stage shadow and can present.
