Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
In the description of the present invention, it is to be understood that, term " on ", "lower", "front", "rear", "left", "right", "top",
The orientation or positional relationship of the instructions such as "bottom", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, merely to just
In description the present invention and simplify description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with
Specific orientation construction and operation, therefore be not considered as limiting the invention.
Referring to Fig.1-2, a kind of projector for knowing figure teaching for installing engineering, including ceiling 1 and mounting plate 2, installation
Plate 2 is fixedly connected on the downside wall of ceiling 1, and electric telescopic rod 3 is fixedly connected on the downside wall of mounting plate 2, electronic to stretch
The bottom end of contracting bar 3 be fixedly connected with micro-step motor 4 (electric telescopic rod 3 and micro-step motor 4 are the prior art,
Working principle and connection type are no longer described in detail herein), the bottom end of electric telescopic rod 3 and micro-step motor 4 it is defeated
Shaft is fixed together, and projector 5 is fixedly connected on the downside wall of micro-step motor 4.
Limiting device is equipped in mounting plate 2, limiting device includes empty slot 6, and empty slot 6 is annular groove, and the setting of empty slot 6 is being installed
In plate 2, sliding block 7 is slidably connected in empty slot 6, multiple grooves are symmetrically arranged in the both ends of sliding block 7, and sliding connects in each groove
It is connected to ball 8, by ball 8, the sliding friction between 6 inner sidewall of the upper and lower ends of sliding block 7 and empty slot is become into rolling friction,
To effectively reduce the frictional force suffered along 6 sliding process of empty slot of annular of sliding block 7, the inner sidewall of empty slot 6 is equipped with rubber
Glue film, rubber membrane is by hindering directly contacting between ball 8 and 6 inner sidewall of empty slot, to effectively avoid because of ball 8 and sky
Noise caused by friction between 6 inner sidewall of slot, and can prevent ball 8 from wearing.
The downside wall of empty slot 6 is equipped with annular opening, slidably connects first body of rod 9 in annular opening, first body of rod 9
One end is fixedly connected on the downside wall of sliding block 7, and sliding slot 10 is equipped in first one end of the body of rod 9 far from sliding block 7, is slided in sliding slot 10
Dynamic to be connected with second body of rod 11, second body of rod 11 is fixedly connected with fixed plate 12, second body of rod 11 far from one end of first body of rod 9
Together with being fixedly connected by welding with fixed plate 12, it is fixedly connected by welding, good fixing effect, globality is strong,
Sound construction is stablized, and load ability is strong, and fixed plate 12 is mounted on projector 5, and the both ends of fixed plate 12 pass through two bolts 13
It is fixedly connected on the upper surface of projector 5, fixed plate 12 is installed on projector 5 by bolt 13, installing and dismounting is all non-
It is often convenient, and the effect being fixedly connected is good.
The switch for opening micro-step motor 4, because of one end of the output shaft of micro-step motor 4 and electric telescopic rod 3
It is fixed together, the other end of electric telescopic rod 3 is fixed together with mounting plate 2 again, and mounting plate 2 is mounted on smallpox
On plate 1, therefore under the rotary action of output shaft, micro-step motor 4 drives projector 5 to rotate around electric telescopic rod 3, carries out
The adjustment of horizontal direction angle, by empty slot 6 to the position-limiting action of sliding block 7, so that two first bodies of rod 9 begin during rotation
Whole keeping parallelism, latter two right second body of rod 11 also keeping parallelism under the position-limiting action of sliding slot 10, to prevent projector 5 from existing
When being rotated under the drive of micro-step motor 4, the case where shaking.
Need to carry out height when adjusting, start electric telescopic rod 3, projector 5 can under the drive of electric telescopic rod 3 into
The height of row up and down direction adjusts, and with stretching for electric telescopic rod 3, second body of rod 11 10 slides up and down along the chute, prevents from throwing
The phenomenon that shadow instrument 5 shakes in height adjustment process, to guarantee projected picture in the mistake of height adjustment and angular adjustment
It keeps stablizing in journey, restores to stablize from shaking because withouting waiting for picture, projector adjusting can be greatly shortened
The required time.
In the present invention, when user uses the device, when needing to carry out highly to adjust, start electric telescopic rod 3, control electricity
Dynamic telescopic rod 3 is flexible, and electric telescopic rod 3 drives the projection being fixedly connected with micro-step motor 4 by micro-step motor 4
Instrument 5 moves up and down, and carries out height adjustment to projector 5, second body of rod 11 10 moves up and down along the chute, needs to carry out horizontal direction
Angular adjustment when, the switch of micro-step motor 4 is opened, because of the output shaft of micro-step motor 4 and electric telescopic rod 3
One end is fixed together, and the other end of electric telescopic rod 3 is fixed together with mounting plate 2 again, therefore miniature stepping
Motor 4 drives projector 5 to rotate around electric telescopic rod 3, and the adjusting of horizontal direction angle is carried out to projector 5；
Sliding block 7 drives first body of rod 9 to rotate around electric telescopic rod 3, two first bodies of rod 9 under the position-limiting action of empty slot 6
Remain parallel during rotation, two second bodies of rod 11 also keeping parallelism under the position-limiting action of sliding slot 10, thus anti-
Only projector 5 shakes during height adjustment and angular adjustment, guarantees the stability of projected picture, withouts waiting for
Projected picture restores to stablize from shaking, and then projector 5 is greatly saved and adjusts the required time.
