The invention relates to the technical field of portable vehicle-mounted projectors, in particular to a portable vehicle-mounted projection display device and a using method thereof. The device comprises a projector body, and an angle adjusting device is arranged at one end of the projector body; the top end and the bottom end of the angle adjusting device are both rotationally connected with limiting devices. Each limiting device comprises a fixing cylinder, a fixing rod, a locking screw, an operation plate, a moving groove, a spring, a push rod, a piston head, a rubber ring and a suction cup. In the present invention, the fixing cylinders, the operation plates, the moving grooves, the springs, the push rods, the piston heads, the rubber rings and the suction cups are arranged; the projector body is placed behind the rear side of an automobile and a worker fixes the suckers and an automobile rear windshield together, so that the projector body is limited and fixed through the effect of the suckers, and the projector body does not incline; meanwhile, air on the inner side of the suckers can be sucked through the effect of the springs and the piston heads, and the suckers and the automobile rear windshield are tightly sucked together.
本发明涉及便携式车载投影仪技术领域,尤其为一种便携式车载投影显示装置及其使用方法,包括投影仪主体,所述投影仪主体的一端设置有角度调节装置,所述角度调节装置的顶端与底端均转动连接有限位装置,所述限位装置包括固定筒、固定杆、锁死螺钉、操作板、移动槽、弹簧、推杆、活塞头、橡胶环和吸盘,本发明中,通过设置的固定筒、操作板、移动槽、弹簧、推杆、活塞头、橡胶环和吸盘,把投影仪主体放置在汽车后侧后,工作人员把吸盘与汽车后挡风玻璃固定在一起,通过吸盘的作用实现对投影仪主体的限位固定,从而使投影仪主体不会出现歪斜的现象,同时弹簧以及活塞头的作用可以对吸盘内侧气体进行抽吸,使吸盘紧紧与汽车后挡风玻璃吸在一起。
