Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Please refer to fig. 1, the utility model provides a novel projection lamp house is used in visual transmission, including base 1, base 1 upper surface right side is provided with fixed block 2, the middle part is provided with bearing frame 3, through-hole 4 has been seted up on the fixed block 2, 4 internal rotations in through-hole are connected with screw rod 5, screw rod 5's left end and bearing frame 3 rotate to be connected, the right-hand member extends to through-hole 4 right side, it is connected with sleeve pipe 6 to rotate on the screw rod 5, 6 upper ends of sleeve pipe articulate has bull stick 7, 1 left side top of base articulates there is projection lamp house 8, the tip of bull stick 7 is articulated with projection lamp house 8's the back. The above constitutes the basic structure of the present invention.
The working principle is as follows: when the projection lamp box is used, the screw rod 5 is rotated, the screw rod 5 drives the sleeve 6 to move left and right along the length direction of the sleeve, and the sleeve 6 drives the projection lamp box 8 to rotate in the moving process, so that the direction of the projection lamp box 8 is adjusted, the projection angle is changed, and the optimal projection effect is achieved.
The invention will be further described with reference to specific examples:
in this embodiment, for protection projection lamp house 8, the upper end of fixed block 2 is rotated and is connected with safety cover 9, when accomodating and depositing, and safety cover 9 prevents that dust and rainwater from spilling on projection lamp house 8 on the box.
