Embodiment

Please refer to Fig. 1, the preferred embodiments of projector 100 of the present invention comprises that a projector main body 10, is provided with camera lens module 20 and a base 30 of camera lens 222.

It is one square that described projector main body 10 is substantially, offers a through hole 162 that is used for ccontaining camera lens 222 on its front panel, and the slightly larger in diameter of described through hole 162 is in the diameter of described camera lens 222.The rear end of described projector main body 10 is provided with a rotating part 12, and the both sides of described rotating part 12 respectively are convexly equipped with a projection 122.The front bottom end of the two side of described projector main body 10 is respectively offered a through hole 142.Wherein, the inside of described projector main body 10 also is equipped with components and parts such as power module, the control module etc. that general projector all has, because described components and parts are prior art all, so locate to be not described in detail concrete structure and the principle of work of described components and parts.

Described camera lens module 20 comprises a camera lens body 22 and one and the runing rest 24 that is rotatedly connected of described camera lens body 22.Described camera lens 222 is located at the front of described camera lens body 22, the corresponding through hole 142 of the front bottom end of the two side of described camera lens body 22 is respectively offered a projection 224, four jiaos of the bottom surface of described camera lens body 22 respectively are convexly equipped with one first web member 226, and it is two parallel and be provided with the protuberance of through hole that described first web member 226 can be designed as.

Described runing rest 24 is roughly a quadra structure, the corresponding described web member 226 in the two ends of its two side is provided with second web member 241, be rotationally connected the respectively end of bull stick 248 of four equal in length of described first web member 226, the other end of described bull stick 248 is corresponding respectively to be rotatedly connected with described second web member 241, a fluting 244 is respectively offered in the antetheca of described runing rest 24 and the both sides of rear wall, a screw 242 is respectively offered at the middle part, and antetheca and rear wall also are provided with two parallel supports 246 between the middle part, also vertically be provided with some plates 2462 in the cell body 2464 between the described two stands 246, on each plate 2462 also corresponding screw 242 offer screw (not label), in other embodiment, also can be entity structure between the described two stands 246, and offer one and run through the antetheca of described support 24 and the screw of rear wall gets final product.

Described base 30 is roughly a quadra structure, its corresponding described screw 242 in antetheca middle part is offered a through hole 32 so that a long bolt 38 moves freely within it, corresponding described fluting 244 is provided with two slide bars 34 between the antetheca of described base 30 and the rear wall, the rotation section 36 that respectively extends back, the two side of described base 30, corresponding described two projections 122 are respectively offered a through hole 362 on each rotation section 36.

Please refer to Fig. 2-4, during assembling, described support 24 is positioned in the described base 30, and described fluting 244 just is stuck on described two slide bars 34, projection 224 on the described camera lens module 22 is stuck in the through hole 142 of described projector main body 10, this moment, described camera lens 222 stretched out outside the described through hole 162, the projection 122 of described projector main body 10 is stuck in the through hole 362 of described base 30, at last described long bolt 38 is put in described through hole 32 back screw locks in the screw corresponding with it of described screw 242 and back, can make described support 24 be positioned the diverse location place of described base 30 by rotating described long bolt 38, be positioned at the middle part as Fig. 2, Fig. 3 is positioned at foremost, Fig. 4 is positioned at the rear end, and then control described camera lens 222 and be on the different height, again because the length of described bull stick 248 is identical, so the bottom of described camera lens module 22 all the time with described base 30 keeping parallelisms, so described camera lens 222 is constant all the time with the angle of surface level, namely when projector 100 work, no matter which height described camera lens 222 is adjusted to, can trapezoidal picture not appear at projection screen all, and according to above-mentioned also very convenient to the adjusting of camera lens 222 height as can be known.
