Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and thus the present invention is not limited to the specific embodiments of the present disclosure.

Referring to fig. 1-4, the present invention provides a technical solution: an adjustable projection stand for film projection comprises a stand 1, a base 11, connecting blocks 2, rotating rods 3, connecting rods 4, a placing plate 10, gears 5, rectangular blocks 6 and worms 7, wherein the base 11 is fixedly arranged on the surface of the stand 1, the connecting blocks 2 are arranged on the top surface of the base 11, the rotating rods 3 are rotatably arranged between the connecting blocks 2, the connecting rods 4 are respectively arranged at two ends of each rotating rod 3, the placing plate 10 is fixedly arranged between the connecting rods 4, the gears 5 are fixedly arranged on the surface of the rotating rods 3, the rectangular blocks 6 are arranged on one side of the base 11, the worms 7 are rotatably arranged in the rectangular blocks 6, the gears 5 are meshed with the worms 7, protective cases 9 are arranged on the surfaces of the base 11 at the positions of the gears 5 and the worms 7, and are driven by the gears 5 and the worms 7, thereby, the angle of the placing plate 10 is adjusted, and the protection shell 9 is arranged to protect the gear 5 and the worm 7.

The one end of worm 7 is equipped with and changes the handle, and the shape of changeing the handle is circular, through setting up worm 7, when worm 7 rotated, worm 7 drove 5 movements of gear this moment, and gear 5 drives after that and places board 10 and rotate to play the effect of adjusting and placing board 10 angle, changeed the handle through setting up circular simultaneously, because circular surface is very smooth, thereby improved people and held the comfort level when changeing the handle, made things convenient for people to rotate worm 7, do benefit to in-service use.

The material of placing board 10 is rubber, and one side of placing board 10 is equipped with baffle 8, sets up to rubber through the material that will place board 10, because the frictional force of rubber is great to when the projecting apparatus is placed and is placing board 10 top surface, played the effect of firm projecting apparatus, simultaneously again because the material of rubber is softer, thereby avoid the projecting apparatus bottom and place the condition that board 10 contact received the frostbite.

One side of stand 1 is provided with dust keeper, dust keeper includes pivot 12, disk 13 and dust-shielding cloth 14, pivot 12 adorns in one side of stand 1 admittedly, the surface rotation of pivot 12 has disk 13, the quantity of disk 13 is two sets of, 13 symmetric distribution of two sets of disks are in the both sides of stand 1, connect dust-shielding cloth 14 through setting up disk 13, spacing dust-shielding cloth 14's effect has been played, disk 13's fixed surface is connected with dust-shielding cloth 14, through setting up dust-shielding cloth 14, when the projecting apparatus needs to be placed for a long time, people can cover dust-shielding cloth 14 at 1 top surface, thereby protect the projecting apparatus on placing board 10, thereby avoid the inside condition that influences the projecting apparatus performance of dust entering projecting apparatus.

The working principle is as follows: through setting up stand 1, base 11, connecting block 2, bull stick 3, connecting rod 4, place board 10, gear 5, rectangular block 6 and worm 7, when people need adjust the projecting apparatus angle, worm 7 rotates this moment, worm 7 drives gear 5 and rotates, gear 5 drives bull stick 3 and rotates in 1 inside stand, last bull stick 3 drives connecting rod 4 and places board 10 and rotates, the effect of placing board 10 angle has been played in the regulation, because baffle 8 is spacing with the projecting apparatus, make it unable from placing 10 surperficial landing of board, through setting up dust keeper, when the projecting apparatus on stand 1 surface no longer uses, pulling dust-shielding cloth 14 this moment, dust-shielding cloth 14 drives circle 13 and rotates in pivot 12 surfaces, at this moment, people can cover the projecting apparatus surface of 14 covers on stand 1 with dust-shielding cloth, the effect of protection projecting apparatus has been played.

The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention in other forms, and any person skilled in the art may apply the above modifications or changes to the equivalent embodiments with equivalent changes, without departing from the technical spirit of the present invention, and any simple modification, equivalent change and change made to the above embodiments according to the technical spirit of the present invention still belong to the protection scope of the technical spirit of the present invention.
