This is formed at the two ends of this common bar 2 respectively one-body moldedly to cam surface 3; And this should be total to bar 2 relatively to cam surface 3 and be symmetry; In this first preferred embodiment, this respectively is the inclined-plane to cam surface 3, and towards the inclination that is directed downwards away from this common bar 2; In other variant, this also can be arc surface to cam surface 3.
This is butted on this respectively to cam surface 3 to driven member 4 one ends, and the other end then passes this housing 1 respectively, and this is positioned at outside this housing 1 to foot pad 5 and is installed on this respectively on the driven member 4.Wherein, this comprises the roller 41 that is butted on this cam surface 3 downwards respectively, passes this housing 1 connecting the vertical rod 42 of this roller 41 and foot pad 5 driven member 4, and installation sleeve is located at the elastic body 43 in this vertical rod 42.
This cam surface 3 is positioned at this roller 41 belows, and this elastic body 43 is a compression spring, and these elastic body 43 1 ends are butted on this housing 1 bottom surface, and the other end is butted on this foot pad 5, and the elastic-restoring force of this elastic body 43 makes these roller 41 perseverances be butted on this cam surface 3 downwards.
This driver element 6 comprise the tooth bar 60 that is formed on this common bar 2, with the driven wheel 61 of these tooth bar 60 engagements, be inserted in these driven wheel 61 centers of circle D font axostylus axostyle 62, be connected the knob 63 of this axostylus axostyle 62; And to being formed at the graduation apparatus 64 on this housing 1 by knob 63; This tooth bar 60 bar 2 together is one-body molded, and this driven wheel 61 drives bar 2 altogether through this tooth bar 60.
Consult Fig. 4 and Fig. 5, this knob 63 of user's application of force rotation rotates this driven wheel 61 through this axostylus axostyle 62; And then through these tooth bar 60 drive bar 2 slippages altogether; In the time of should being total to bar 2 slippages, wherein cam surface 3 can upwards push against the roller 41 of correspondence and compress this elastic body 43, and another roller 41 then reduces height synchronously; This drives this to driven member 4 foot pad 5 is adjusted distance synchronously; Just when the distance of 1 of wherein a foot pad 5 and this housing shortened, the distance that another foot pad 5 and this housing are 1 was then elongated relatively, reached the effect at adjustment inclination angle synchronously and expediently.
As shown in Figure 4, when this driven wheel 61 clockwise rotated, this was that a left side is low right high to foot pad 5 lifting trends, and then driving this housing 1, to be a left side low right high, as shown in Figure 5, and to be a left side high right low for 1 of this housing when this driven wheel 61 rotates counterclockwise.
Consult Fig. 6; Second preferred embodiment of the dip angle adjusting mechanism of projector of the present invention and this first preferred embodiment member and assembling mode are roughly the same, and difference is in this second preferred embodiment, is to utilize the motorized motions mode to replace the manual drives mode; In this second preferred embodiment; This driver element 6 comprises this tooth bar 60 and driven wheel 61 equally, also comprises in addition to drive the motor 65 that this driven wheel 61 rotates, and two buttons 66 that are electrically connected this motor 65.
The user pushes these buttons 66 and drives this to foot pad 5 synchronous adjustment distances through this motor 65.In addition, also can use this motor 65 of remote control mode control (figure does not show).
Consult Fig. 7; The 3rd preferred embodiment of the dip angle adjusting mechanism of projector of the present invention and this first preferred embodiment member and assembling mode are roughly the same; Difference is in the 3rd preferred embodiment, and this driver element 6 also comprises the idle pulley 67 that is engaged in 60 of this driven wheel 61 and this tooth bars.Through this idle pulley 67, when changing this driven wheel 61 of rotation, the trend that this goes up and down to foot pad 5, just when this driven wheel 61 clockwise rotated, it is high right low that this housing 1 is a left side, opposite with Fig. 4 trend.
Consult Fig. 8, the 4th preferred embodiment of the dip angle adjusting mechanism of projector of the present invention and this first preferred embodiment member and assembling mode are roughly the same, and difference is in the 4th preferred embodiment; This is inclined upwardly towards the direction away from this common bar 2 to cam surface 3, and just in this 4th preferred embodiment, this vergence direction to cam surface 3 is opposite with first preferred embodiment; By this; When changing this driven wheel 61 of rotation, the trend that this goes up and down to foot pad 5 is just when this driven wheel 61 clockwise rotates; It is high right low that this housing 1 is a left side, opposite with Fig. 4 trend.
Consult Fig. 9; The 5th preferred embodiment of the dip angle adjusting mechanism of projector of the present invention and this first preferred embodiment member and assembling mode are roughly the same; Difference is in the 5th preferred embodiment that this driver element 6 comprises the elongated slot 68 that is opened on this housing 1, and is installed on this common bar 2 and protrudes from the outer driving lever 69 of this elongated slot 68; The user is through stirring the slippage in this elongated slot 68 of this driving lever 69, and then drives altogether that bar 2 moves back and forth.
In addition, in this 5th preferred embodiment, this is positioned at this pair roller 41 tops to cam surface 3, and this is located at this housing 1 inside to elastic body 43, and is positioned at 41 on this housing 1 and roller, makes these roller 41 perseverances upwards be butted on this cam surface 3.
In sum; Drive this common bar 2 toward polyslip by this driver element 6, make this common bar 2 push against this to driven member 4 to cam surface 3, make this drive this foot pad 5 is adjusted distance synchronously driven member 4 through this; When just wherein the distance of 1 of a foot pad 5 and this housing shortens; The distance of another foot pad 5 is then elongated relatively, reaches the effect at adjustment projector inclination angle synchronously and expediently, so can reach the object of the invention really.
The above is merely preferred embodiment of the present invention, can not limit the scope that the present invention implements with this, and promptly all simple equivalent of doing according to claim of the present invention and invention description change and modify, and all still belongs in the scope that patent of the present invention contains.
