Abstract

The utility model discloses an optical projector adjusting device of projection display terminal. At least two adjusting plates are fixed pairwise by a bolt at the bottom of a case. An optical projector is fixed on an upper adjusting plate. Five-axle adjusting part with five freedoms are arranged on the upper adjusting plate and a lower adjusting plate to make the optical projector to rotate and translate along the X axle and the Y axle and rotate along the Z axle. Because the position of the adjusting plate is adjusted to realize the five-axle adjusting of the optical projector, therefore, the virtual light point of the optical projector and the light axle are fixed on only assured point and orientation lest the infidelity of image on the display screen from the optical projector occurs and is not matching with the screen frame; therefore, the utility model has food visual effect.

Description

The optical projection machine adjusting gear of Projection Display terminal

Technical field

The utility model belongs to the optical projection machine adjusting gear of Projection Display terminal, specifically a kind of adjusting gear of correcting the optical projection machine geometric error of Projection Display terminal.

Background technology

Common Projection Display terminal, generally include optical projection machine, one or two catoptron and be used for display image screen, during work, the image that the optical projection machine sends projects on the screen of display image by catoptron.General optical projection system, liquid crystal silicone optical projection system for example, self can not correct geometric error.Whether the position of optical projection machine is correct, is related to the whether distortion of the image that projects on the screen, and the problem of whether mating with the screen frame.Existing optical projection machine owing to can not carry out multi-faceted adjustment, often causes the several picture distortion and does not match with the screen frame after installation, has influenced visual effect.

The utility model content

Be the problem that solves optical projection machine several picture distortion and mate with the screen frame, the technical solution of the utility model is: on the bottom surface in casing, upwards three adjustable plates are fixing in twos successively with bolt, the optical projection machine is fixed on the adjusted plate, on each adjustable plate, be respectively equipped with and make the optical projection machine along X, Y-axis translation and rotation and five governor motions rotating, have five degree of freedom along the Z axle.

Owing to utilize the position adjustment of adjustable plate, can realize five axial adjustment of optical projection machine, thereby it is fixing that the virtual luminous point of optical projection machine and optical axis are set up behind well-determined point and the orientation, avoided the optical projection machine to project the distortion of several picture on the display screen, and with the unmatched problem of screen frame, so visual effect can reach best.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is used for the stereographic map of televisor for the utility model;

Fig. 2 is for being used for the parts installation site stereographic map that the optical projection machine is adjusted among Fig. 1;

Embodiment

Among Fig. 1, on the bottom surface 2 in casing 1, upwards with bolt that end adjustable plate 3, middle adjustable plate 4 and adjusted plate 5 is fixing in twos successively, optical projection machine 6 is fixed on the adjusted plate 5.

Among Fig. 2, at the two ends of end adjustable plate 3 shown in Figure 1, be respectively equipped with the microscler bolt hole 7 of crossing, bolt 8 passed bolt hole 7 and was screwed on the bottom surface 2 in the casing 1.Unclamp bolt 8, end adjustable plate 3 is regulated in the length direction displacement in hole.

On four angles of the middle adjustable plate 4 on be installed on end adjustable plate 3, be provided with microscler the cross bolt hole 9 vertical with the length direction in hole on the end adjustable plate 3, bolt 10 passed bolt hole 9 and was screwed on the end adjustable plate 3, unclamp bolt 10 equally, adjustable plate 4 is regulated in the adjusting direction displacement perpendicular to end adjustable plate 3 in can making; Simultaneously, three points at two ends are provided with screw on middle adjustable plate 4, and the support pin 12 of lower end dribbling head is screwed in three screws, and its bulb withstands on 3 of the end adjustable plates; Unclamp bolt 10, turn support pin 12, the bulb of support pin 12 withstands on the end adjustable plate 3, because end adjustable plate 3 is motionless, middle adjustable plate 4 is along with the rotation that turns different support pins 12 is risen and fallen to different directions, thereby its plate is tilted towards any direction.

In being installed on above the adjustable plate 4, with the fixing adjusted plate 5 of optical projection machine on, be provided with the deep-slotted chip breaker 11 that can pass bolt 13, fixing on the adjustable plate 4 during bolt 13 is screwed in; Unclamp

bolt

13,5 of adjusted plates can be regulated along the direction of deep-slotted chip breaker 11.Adjusted plate 5 can be with three bolt, the deep-slotted chip breaker 11 of crossing bolt on it can be three that are distributed on the circle in the same center of circle, also can be that a circular hole is wherein arranged, and two is the deep-slotted chip breaker 11 on the circle in the same center of circle, during adjustment, two deep-slotted chip breakers 11 change around the center of circle of a circular hole.

The adjustment respectively of adjustable plate of the above-mentioned end 3, middle adjustable plate 4 and adjusted plate 5 or part are adjusted, can realize that the optical projection machine its top installed is along X, Y-axis translation and rotation and five axial adjustment of rotating along the Z axle, it is fixing that the virtual luminous point of optical projection machine and optical axis are set up behind well-determined point and the orientation, guaranteed that several picture is undistorted and with the screen frame good coupling is arranged.

The adjusting gear of adjustable plate 3, middle adjustable plate 4 and adjusted plate 5 at the bottom of the above-mentioned band, hole of being opened on it and the support pin of installation 12, office does not only limit to aforesaid way, for example can be on end adjustable plate 3 and middle adjustable plate 4, to be provided with the orthogonal bolt hole 7 or 9 of crossing, on adjusted plate 5, be provided with deep-slotted chip breaker 11 and support pin 12, perhaps on middle adjustable plate 4, be provided with deep-slotted chip breaker 11, on adjusted plate 5, be provided with microscler bolt hole excessively etc.; Any exchange mode that may realize above-mentioned five adjustings that also has other is all in protection domain of the present utility model.

The utility model is suitable for the electric equipment of all band Projection Display terminals.
