Abstract
The utility model discloses a film projecting apparatus capable of adjusting digital projection optic-axis pitch angle, comprising a base. The bottom face of the base is provided with an adjusting screw whose supporting height can be adjusted. The number of the adjusting screw is four. The four adjusting screws are divided into two groups and arranged on both sides of the front end part and the rear end part of the bottom face of the base seat. The base seat is formed by connecting two plate elements in a hinged mode. The utility model adopts the structure, realizes that the digital projection optic-axis pitch angle of a digital film projecting apparatus in the certain range can be optionally adjusted by adjusting the supporting height of the adjusting screw and the positioning position of the base seat hinged structure, and the utility model is safe, quick and convenient in operation.
Description
Technical field
The utility model relates to digital film projector equipment, is specifically related to a kind of projection equipment of the tunable integers word projection optical axis angle of pitch.
Background technology
Existing digital film projector equipment generally has a base in order to support body part, and this base is only played a supporting role, and the adjustment of the numeral projection optical axis angle of pitch of therefore existing digital film projector equipment generally is to realize by body or external article pad holder.Yet; in the use of reality; regular meeting needs to adjust greatly at the scene the numeral projection optical axis angle of pitch of projection equipment because of the singularity in projection place; existing digital film projector equipment then is difficult to satisfy this specific demand; and labor capacity is big and dangerous, also can influence the reliability of digital show quality.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of projection equipment of the tunable integers word projection optical axis angle of pitch is provided, and it can easily realize the arbitrarily adjustment within the specific limits of the numeral projection optical axis angle of pitch.
For achieving the above object, the technical solution of the utility model is as follows: the projection equipment of the tunable integers word projection optical axis angle of pitch has a base; Described base end face is equipped with the set screw of adjustable support height, and the optical axis of numeral projection projector equipment can accurately be adjusted according to the projection field condition neatly.
Above-mentioned set screw is four, is divided into two groups of leading section and rearward end both sides that are installed in base end face respectively.
Above-mentioned base is formed by connecting by articulated manner by two boards spare, and the optical axis of numeral projection projector equipment can accurately be adjusted according to the projection field condition neatly
The utility model is owing to adopt said structure, by the bearing height of adjustment set screw and the position location of base articulated structure, can realize the numeral projection optical axis angle of pitch arbitrarily adjustment within the specific limits of numeral projection projector equipment, and it is safe, quick, easy to operate.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the action synoptic diagram one that the utility model realizes adjusting the numeral projection optical axis angle of pitch;
Fig. 3 is the action synoptic diagram two that the utility model realizes adjusting the numeral projection optical axis angle of pitch.
Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
Embodiment
As shown in Figure 1, the utility model has a base 1, and base 1 is formed by fraising 12 on the two plate sides and fraising screw 13 coordination hinges by two boards spare 11.Support body part 2 above plate 1 wherein. Set screw 3 and 4, four set screw 3 of four road wheels that four adjustable support height are equipped with in base 1 bottom surface are divided into two groups of leading section and rearward end both sides that are installed in base end face respectively.
As shown in Figure 1, by regulating the fraising screw, can make the plate of support organism part form the angle of inclination, and cooperate the bearing height of adjusting set screw, can realize the accurate adjustment of the numeral projection optical axis angle of pitch of numeral projection projector equipment with respect to another plate.
Claims (3)
