[0027] Example

[0028] Refer Figure 1-6 A film and television lamination screen supports the anti-pouring device, including the screen body 1 and two base 2, and the upper end of the two base 2 is provided with a support mechanism, and the support mechanism includes a mounting frame 3, mounting frame 3, which is fixed to the upper end of the base 2. The side wall is rotated to be connected to the support frame 4. The bottom of the support frame 4 is opened, and the inner wall of the storage tank 5 is rotated and connected to the support plate 6. The upper end of the base 2 is opened with a card slot 7, and the inner wall of the card slot 7 is fixed. A block 8, one of the block 8 is in place with the support plate 6, and the sidewall of the support frame 4 is opened, and the inner wall of the adjustment tank 9 is rotated and connected to the adjustment screw 10, and the end portion of the support frame 4 is fixedly adjusted. The motor 11, the output shaft of the adjustment motor 1...

Abstract

The invention discloses a supporting anti-toppling device for film and television projection screen, wherein the device comprises a screen body and two bases; supporting mechanisms are arranged at the upper ends of the two bases, each supporting mechanism comprises a mounting frame fixed to the upper end of the corresponding base, the side wall of each mounting frame is rotationally connected with a supporting frame, and a storage groove is formed in the bottom of each supporting frame; and a supporting plate is rotationally connected to the inner walls of the storage grooves, a clamping groove is formed in the upper end of each base, a plurality of clamping blocks are fixed to the inner walls of the clamping grooves, one clamping block abuts against the supporting plate, and an adjusting groove is formed in the side wall of the supporting frame. The device has the advantages that the supporting frame, the supporting plate and the bases form a triangular structure, the acting force of the screen body is decomposed and acts on the supporting plate and the supporting frame, the triangular structure is kept stable, the bases are tightly attached to the ground, the situation of overall toppling is avoided, and thus the stability of equipment placement is guaranteed.

Description

technical field [0001] The invention relates to the technical field of screen support, in particular to a screen support anti-dumping device for film and television projecting. Background technique [0002] Screen, which refers to the white screen that displays the projection when playing a movie, is widely used in theme parks, museums, studios, TV and film studios, scenic spots, churches, medical and educational facilities, and conference rooms; [0003] When the screen is in use, it usually needs to be supported to meet the projection requirements. At present, the support for the screen is basically in the form of binding the support rod around the support column with a drawstring, which is completed by bolt fixing, rope binding, etc. There is also instability in itself, so that even if the screen and the supporting parts are combined stably, the overall stability is still insufficient, and most of the supporting parts are directly placed vertically, if the angle adjustmen...
