Description
Technical field
The invention belongs to projection field, specially refer to a kind of suspension type projector bracket.
Background technology
The application of projecting apparatus is very universal, such as to one's name special projecting apparatus all can be installed in the place such as meeting room, classroom. The mounting means of these projecting apparatus is normally fixed under furred ceiling by suspension type projector bracket.
Traditional suspension type projector bracket, once the base of support is fixed under building furred ceiling, projecting apparatus, with respect to the position of bracket base, can only do upper-lower position adjustment, can not do front and back or the adjustment of position, left and right; This that is to say traditional suspension type projector bracket, and projecting apparatus cannot be adjusted with respect to the front and back of curtain or the position of left and right. The upper and lower adjusting of backing positions of projecting apparatus place is equivalent to the adjusting of lower trapezoid on projecting apparatus, and the adjusting of projecting apparatus place backing positions left and right is equivalent to the adjusting that the adjusting of the trapezoidal adjusting in projecting apparatus left and right, front and back is equivalent to projecting apparatus focal length.
Common projecting apparatus does not possess the trapezoidal adjustment function in left and right, aim at the central vertical line of curtain so must make projector lens when projecting apparatus is installed, otherwise the picture projecting will produce the trapezoidal deviation in left and right, but when projector mount is installed, might not make projector lens aim at the position of the central vertical line of curtain. Again because focal length (focus is to change projected picture size) adjustable extent difference and adjustable scope of various dissimilar projecting apparatus are very limited. So the function whether projector mount has left and right, front and back adjusting to projecting apparatus position just seems even more important.
Be the disclosed suspension bracket for projector of CN200910030479 in the patent No., be also mentioned to the position (original text is recorded: the vertical angle of lifting sleeve is adjustable) that can regulate projecting apparatus place support; But still there is following problem in this projector mount: one, the base of support (original text claims: base plate) is fixed on after furred ceiling, can only have direction to regulate the position (as: can only swing) of projecting apparatus, can not omnibearingly regulate; Two, because of the distance between the strong point (original text: 51,52 distance in figure) very near (far away if the distance between the strong point becomes, angle adjustable scope just diminishes), after installation projecting apparatus, firmness is not strong. In addition, this patent is mentioned as lift adjustment inner sleeve, outer tube, adopts the mode of nut, screw, perforation to connect adjusting, has level to regulate (being that quantity and the position that adjusting position is bored a hole limits) so belong to; The adjusting of lifting is also not too convenient in addition.

6, connect after support bar 2 and translot 3, then with the first bolt 213 through the first circular hole 212, looping pit 15, screw in first screw 141 of annulus egative film 14 of base 1, support bar 2 is arranged on to the below of base 1.
7, horizontally rotate support bar 2, the level that namely regulates translot 3 towards, the first bolt 213 is screwed; Regulate respectively and under two, manage 22 positions in upper pipe 21, namely regulate upper-lower position and the gradient of translot 3, the second bolt 223 and the 3rd bolt 234 are screwed; Skidway hole 31 directions towards translot 3 regulate translot 3 positions, and the 4th bolt 34 is screwed.
8, projecting apparatus is arranged on suspension 4, select a pair of shaft 32 at the right and left of translot 3, suspension 4 is hung thereon by opening 411, and the 5th bolt 42 is screwed in the screw 33 of translot 3 through the arcuate socket 412 of suspension 4, regulate after projecting apparatus, the 5th bolt 42 is screwed.
If 9 steps 8 can not be adjusted to appropriate location, can get back to step 7 and adjust again.
In the above in described regulating step, if projecting apparatus cross from curtain close to or excessively far away so that projecting apparatus cannot reach by focusing suitable projected picture size. In such cases, can, by regulating the distance of projecting apparatus from curtain, reach suitable effect. Method can be as follows: translot is adjusted to vertical with curtain (being that one end of translot is towards curtain), and by translot under support bar backward or move forward, and the suspension that projecting apparatus is installed hangs over rear portion or the anterior position of translot selectively.
If the position of projector lens not on the central vertical line of corresponding curtain, causes the picture projecting and forms the trapezoidal deviation in left and right, in such cases, can, by regulating the position, left and right of the corresponding support bar of projecting apparatus, reach suitable effect. Method can be as follows: translot is adjusted to parallel with curtain, and translot is moved to the left or to the right under support bar, and the suspension that projecting apparatus is installed hangs over the left side of translot or the position on the right selectively.
Above-described control method is not unique; In a word, can rotary support bar, regulate two under pipe in the position of upper pipe and regulate the position of translot with the direction of the skidway hole of translot, realize the effect needing.
Shown in accompanying drawing 6 is a kind of floor map being connected and installed of present embodiment, manages the height difference at 22 places under its two, forms translot 3 and tilts to install, and projecting apparatus can select to hang over higher position, also can hang over lower position.
Above-described is only one embodiment of the present invention, and to one skilled in the art, under the premise without departing from the principles of the invention, some that make change, and all should be considered as belonging to protection scope of the present invention.
