In order to solve the above problems, a new technical solution is provided.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a 3D liquid crystal splicing screen to solve the problems raised in the above background technology.

In order to achieve the above purpose, the present invention adopts the following technical solutions: a 3D liquid crystal splicing screen, including a main body and a 3D liquid crystal screen, the main body is provided with a fixing groove, a base and a square shaft sleeve, and the fixing groove is symmetrically opened on the front and rear of the main body. and the fixing grooves are equally spaced with fixed screw holes, the base is welded to the bottom of the main body, the square shaft sleeve is equidistantly sleeved on the main body, the square shaft sleeve is provided with a connecting rod and a transmission nut, the connecting rod It is welded on the front end corner of the square shaft sleeve, the outer end of the connecting rod is welded with a shaft hole, the transmission nut is welded in the middle of the rear end of the square shaft sleeve, and the 3D LCD screen is installed and fixed on the front end of the shaft hole by screws.

Preferably, the drive nut is threadedly connected with a drive screw, the bottom of the drive screw is welded with a hexagonal column, the bottom of the hexagonal column is connected with a support block through bearing interference, and the middle of the front end of the support block is integrally connected with a plug connection piece.

Preferably, the plug-in block is nested in the fixing groove, the plug-in block is provided with a through hole, and the through hole is threadedly connected with the fixing screw hole through a fastening bolt.

Preferably, the distance between the 3D liquid crystal screens is 9 mm.

Compared with the prior art, the beneficial effects of the utility model are: the base of the utility model is welded to the bottom of the main body, and the main body can be easily placed; the square shaft sleeve is equidistantly sleeved on the main body, so that the square shaft sleeve can easily follow the main body Sliding up and down; the through hole is threadedly connected with the fixing screw hole through the fixing bolt, and the support block can be easily installed and fixed in the fixing groove; the bottom of the hexagonal column is connected with the supporting block through the bearing interference, which can be easily driven by the hexagonal column. Rotation; the drive nut is threadedly connected with a drive screw, which can easily drive the square shaft sleeve to move up and down through the drive screw.
