Embodiment
Below in conjunction with accompanying drawing 1 to Fig. 3 and embodiment, the utility model is described in further detail:
Embodiment 1
Two-sided interlock pitching lift device, as shown in Figure 1 to Figure 3, comprise raising platform 19 and front display screen 2, the back side of front display screen 2 arranges rear display screen 3, raising platform 19 is fixed with pitching motor 11, pitching motor 11 is connected with rotating disk 20, and rotating disk 20 is connected with connecting rod 21, and connecting rod 21 is fixedly connected with the rotating shaft 4 that front display screen 2 is arranged; Rotating shaft 6 is shielded after installing in front display screen 2 back side, and rear screen rotating shaft 6 is socketed draw ring 8, and draw ring 8 is connected by wire rope 9 with rotating disk 20.Rear screen rotating shaft 6 is connected by wire rope 9 with rotating disk 20, thus achieves the interlock of front display screen 2 and rear display screen 3.
Rotating shaft 4 is socketed on back shaft.Pitching limit switch 13 is set between pitching motor 11 and rotating disk 20.Prevent front display screen 2 from overturning excessively by pitching limit switch 13.
Also comprise frame 1, arrange lifter rack 16 in frame 1, raising platform 19 is also provided with upgrading motor 10, and upgrading motor 10 is connected with lifter wheel 22, and lifter wheel 22 coordinates with lifter rack 16.Raising platform 19 can oscilaltion on lifter rack 16.
Also arrange the positioning track 17 of one or more in frame 1, the lower end of raising platform 19 arranges slide block 18, and positioning track 17 is arranged in slide block 18.By positioning guide rail 17, improve stability when raising platform 19 is elevated.
Lower position switch 14 is set below raising platform 19.Rear screen rotating shaft 6 two ends are fixed by rear screen gland 7, and rear screen gland 7 is bolted to connection with front display screen 2.
Be fixedly connected with by spring hinge 5 between rear display screen 3 with front display screen 2.Rear screen rotating shaft 6 is socketed spring hinge 5, and spring hinge 5 is fixedly connected with rear display screen 3.
Utility model works principle is as follows: pitching motor 11 rotates forward and drives rotating disk 20 to rotate forward, and drivening rod 21 rotates around back shaft, and connecting rod 21 and rotating shaft 4 are for being fixedly connected with, therefore rotating shaft 4 also rotates around back shaft.And display device entirety and rotating shaft 4 are for being rigidly connected, so display device does pitching movement backward.Because wire rope 9 is around on rotating disk 20, therefore drive wire rope to pull draw ring 8 downwards, because draw ring 8 is fixedly connected with interior postpone screen display display screen 3, and interior postpone display screen 3 and front display screen 2 or liquid crystal screen aluminum hull are connected by rear display screen rotating shaft 6, so when wire rope 9 by draw ring 8 toward time drop-down, interior postpone display screen 3, around rear display screen rotating shaft 6 pitching, owing to being driven by same pitching motor 11, therefore can be synchronized with the movement.The luffing angle of interior postpone display screen 3 is determined by the diameter of wire rope 9 around rotating disk 20, therefore can keep an optimum field angle.
Pitching motor 11 reverses and drives rotating disk 20 to reverse, and drivening rod 21 rotates around back shaft, and connecting rod 21 and rotating shaft 4 are for being fixedly connected with, therefore rotating shaft 4 also rotates around back shaft.And display device entirety and rotating shaft 4 are for being rigidly connected, so display device does forward pitch motion.Because wire rope 9 is on rotating disk 20, therefore wire rope 9 unclamps, owing to having installed spring hinge 5 between interior postpone screen display display screen 3 and front display screen or display screen aluminium shell, so by interior postpone display screen 3 toward pulling back, until front display screen or display screen aluminum hull get back to 90 degree, rear display screen 3 is withdrawn into and closes up with display device aluminum hull by the length that wire rope 9 unclamps enough spring hinges 5 completely.Owing to being drive 11 by same pitching motor, therefore can be synchronized with the movement.The luffing angle of postpone display screen 3 is determined by the diameter of wire rope 9 around rotating disk 20, therefore can keep an optimum field angle.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
