Abstract
The utility model relates to a bracket of a projector, which comprises a base, a fixed guide rail, a sliding guide rail and a projector fixing tray, wherein the fixed guide rail is connected with the sliding guide rail; the projector fixing tray is fixed on the sliding guide rail; the bracket of the projector is characterized in that the base is internally and rotatablely connected with a screw rod which is rotatablely connected with a screw rod nut; and the screw rod nut is fixedly connected with the fixed guide rail. The bracket of the projector is reasonable in structure and design, solves the problem of inaccurate relative mounting position between the bracket of the projector and a white board by adjusting the bracket of the projector up and down, and leads the projection to be accurately and properly projected on the white board by later period adjustment.
Description
Technical field
The utility model relates to a kind of projector support.
Background technique
Projector's support of prior art, comprise base, fixed guide, slide guide and projector's fixed tray, fixed guide is connected with slide guide, and projector's fixed tray is fixed on the slide guide, fixed guide directly is fixed on the base, and projector is installed on projector's fixed tray.During use, by fixed guide and slide guide projector can before and after regulate, but if carry out up-down adjustment, then need and will move before and after the whole projector support, extremely inconvenient.
The model utility content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and projector's support of a kind of reasonable in design, projector's conveniently moving is provided.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of projector support, comprise base, fixed guide, slide guide and projector's fixed tray, and fixed guide is connected with slide guide, and projector's fixed tray is fixed on the slide guide; It is characterized in that: be rotatably connected to screw mandrel in described base, be rotatably connected to the feed screw nut on screw mandrel, the feed screw nut is fixedlyed connected with fixed guide.
The utility model is equipped with on described feed screw nut and marks closely screw, and the base plate on marking closely screw and being fixed on base cooperates.
Screw mandrel described in the utility model is vertical with fixed guide.
The utility model has guiding groove on described base plate, feed screw nut's a end is positioned at guiding groove.
The utility model compared with prior art has following positive effect: 1, reasonable in design; But projector's support of 2 up-down adjustment can solve projector's support and the inaccurate problem of blank relative installation, by the adjustment in later stage, makes accurately suitable being projected on the blank of projection.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment:
Referring to Fig. 1～Fig. 6, the utility model embodiment comprises base 1, fixed guide 2, slide guide 3 and projector's fixed tray 4.
Fixed guide 2 is connected with slide guide 3, and slide guide 3 can move along fixed guide 2.Projector's fixed tray 4 is fixed on the slide guide 3.
Be rotatably connected to screw mandrel 5 on base 1, be rotatably connected to feed screw nut 6 on screw mandrel 5, feed screw nut 6 is fixedlyed connected with fixed guide 2.Screw mandrel 5 is vertical with fixed guide 2.At the two ends of screw mandrel 5 bearing 7 is installed, the bearing 7 outer bearing supports 10 that are fixed on the base 1 that are set with.Be equipped with on feed screw nut 6 and mark closely screw 8, the base plate 9 on marking closely screw 8 and being fixed on base 1 cooperates.
Head or afterbody at screw mandrel 5 are fixed with hexagon prism.Have guiding groove on the base plate 9, feed screw nut's 6 one ends are positioned at guiding groove.Base plate 9 can be a monolithic construction with base 1, also can be the sectional type structure.
During use, base 1 is fixed on the vertical metope.Rotate hexagon prism with instruments such as spanners, screw mandrel 5 rotates.When screw mandrel 5 rotated, feed screw nut 6 relied on the screw-thread fit of screw mandrel 5 and obtains power.The guiding groove of base plate 9 can prevent that feed screw nut 6 from rotating, thereby realizes that projector's fixed tray 4 relative blanks move up and down.
