Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, the utility model base 1 becomes by four pieces of aluminium sheet nuts and screw association, two pieces of short aluminium sheets borings and a bearing 4 is respectively installed, match with bearing in screw mandrel 3 one end, the other end and bearing fit, and screw mandrel 3 passes nut 2-1 again and coordinates with it. nut 2-1 is welded on the mid-way bottom slide plate 2, slide plate 2 can slide on aluminium sheet, under scissors-type support, base plate 5 and slide block 2 are connected to a fixed position with screw-nut, under first scissors-type support, under base plate fixing feet frame 6 and the 2nd scissors-type support, base plate fixing feet frame 20 is fixed on the two ends of chute 22, on scissors-type support, base plate moves base plate under 10 and scissors-type support and moves cylinder pin frame 23 and can slide in chute 22 in addition, the frictional force that cylinder pin frame slides in chute is very little, so scissors-type support can rise stably and decline, pillar 9 and back up pad 7 screw and nut connect, screw 16 connects pillar 9 and electric pushrod, on electric pushrod outer tube 15 and scissors-type support, base plate 11 screw and nut connect, base platform 12 is placed on scissors-type support on base plate 11, crank 14 can do circumferential motion in the chute of base disk 18-1, column 19 and base platform 12 fixedly mount, can base for supporting disk 18, projector is placed framework 17 and is placed on base disk 18.Axle journal one end of screw mandrel 3 is connected with electric motor, and the circumferential motion of crank 14 is driven by electric motor.
The transmission of the utility model feed screw nut is that the rotary motion of screw mandrel is transformed to nut translational motion. Screw nut driving compact construction, leading screw rigidity is better, and the axle journal one end fits of the steady screw mandrel of transmission speed installs a gear, by electric motor driven gear engaged transmission, electric motor is connected with wireless remote control module, it is possible to realize the rotating of telepilot controlled in wireless electric motor. The rising of scissors-type support and the power of decline come from the expansion link 13 of electric pushrod; the motor internal of electric pushrod is connected with wireless remote control module; can with the rotating of telepilot controlled in wireless motor; realize rising and the decline of expansion link 13; such that it is able to drive the rising of scissors-type support and decline, and the inside of electric pushrod is provided with limit switch, when the expansion link of electric pushrod reaches capacity position; motor automatic stop remains in operation, and reaches the effect that can protect scissors-type support. Crank 14 does circumferential motion in chute, the angular adjustment of base disk can be realized, crank 14 is that the electric motor being connected by wireless remote control module drives in addition, and wireless module can control the rotating of electric motor, adjusts such that it is able to the just mediation realizing base disc angle is counter.
The upper limit and the lower limit distance of the utility model expansion link 13 are 200mm, because the vertical range regulating projector only needs fine setting, so the distance of the rising of expansion link 13 and decline meets to require.
The utility model device suspended fixing is on furred ceiling, the curtain that projector is placed in framework preliminary alignment projector, but there is the position deviation between projector and curtain, or after long-time use, position deviation is there is between projector and projection screen, at this moment just tentatively can be judged by the eyes of people on ground, if there is deviation at level attitude in the position of projector and projection screen, just can with the electric motor of telepilot controlled in wireless screw mandrel, the rotating of control electric motor, drive the rotation of screw mandrel, the translational motion of nut it is transformed to by the rotary motion of screw mandrel, thus the right position realizing slide plate moves, reach the adjustment of level attitude, after level attitude regulates, if there is deviation in vertical position in projector and projection screen, telepilot controlled in wireless electric pushrod can be passed through, the speed that the expansion link of electric pushrod rises and decline runs is very steady, the rising of scissors-type support and decline can be realized by the motor positive and inverse of electric pushrod accurately and electric pushrod inside is provided with limit switch, the telescopic end of electric pushrod is played a protective role, after the level attitude of projector and vertical position regulate, if there is angle problem between projector and projection screen, the electric motor of crank just can be controlled by wireless remote control, realized by the rotating of electric motor that the just mediation of the angle of projector is counter adjusts, thus finally realize being directed at completely of projector and curtain.
