Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, in an embodiment of the present invention, a huge projection curtain dedicated for exhibition halls includes a projection curtain body 1 and a support frame 2;

rotate on the support frame 2 and be connected with the rolling wheel 3, projection curtain body 1 is around establishing on rolling wheel 3, fixedly connected with and projection curtain body 1 matched with U-shaped limiting plate 4 on the support frame 2, and the side rotation is connected with first spacing wheel 5 about U-shaped limiting plate 4, and projection curtain body 1 is located between two first spacing wheels 5.

Gyro wheel 6 is installed to the lower extreme of support frame 2, is convenient for realize through setting up of gyro wheel 6 that support frame 2 removes.

Fixedly connected with motor 7 on support frame 2, motor 7's drive shaft and rolling wheel 3 fixed connection, motor 7 work realizes that rolling wheel 3 rotates.

The support frame 2 is provided with a second limiting wheel 8 matched with the projection curtain body 1, and the limiting effect of the projection curtain body 1 is convenient to realize due to the arrangement of the second limiting wheel 8.

Equal fixedly connected with support 9 on the lateral wall about U-shaped limiting plate 4, first spacing wheel 5 rotates to be connected on support 9.

A groove 10 is formed in the first limiting wheel 5, a connecting rod 11 is elastically connected in the groove 10, and one end of the connecting rod 11 penetrates through the side wall of the groove 10 and is fixedly connected with a limiting plate 12.
