Compared with the solutions in the prior art through openings or the matching of screws and screw holes, this embodiment realizes the sliding member 20 and the fixing member 10 by controlling the friction between the sliding member 20 and the fixing member 10. Relatively sliding and fixing, the arbitrary adjustment and fixing of the position of the display device improves the convenience and accuracy of the position adjustment of the display device, and improves the efficiency of the position adjustment of the display device.

As shown in Figure 1, in this embodiment, the display device may be a display instrument, a display frame, a laser projection screen, etc., and the side of the display device facing away from the display screen is the back of the display device. The back of the display device is fixedly connected with the fixing member 10. The display device adjusting device 100 shown in FIG. 1 is a side surface of the fixing member 10 facing away from the display device.

As shown in FIG. 2, the fixing member 10 is in a plate shape as a whole, and is made of a material with good thermal conductivity, for example, a metal material; it is convenient to conduct and dissipate the heat generated by the display device in the working process to the air. In; the shape of the side surface of the fixing member 10 facing the display device corresponds to the shape of the back of the display device, which is convenient for fitting with the back of the display device, and better fixes the display device.

At least one connecting mechanism 11 is provided on the fixing member 10, and the connecting mechanism 11 is used to connect the fixing member 10 with the display device. In this embodiment, the fixing member 10 is a rectangular plate. A side surface of the fixing member 10 facing the display device is provided with screw holes, and the positions of the screw holes are generally arranged at four corners of the fixing member 10.

In other embodiments, the fixing member 10 and the display device may also be connected by other movable mechanisms; for example, a hook is provided on the back of the display device, and the fixing member 10 faces a side surface of the display device. Correspondingly, a hook or a hanging port is provided, and the hook on the fixing member 10 is in the same position and opposite to the hook or hanging port on the back of the display device, which is convenient for hanging the display device on the fixing member 10. The fixing member 10 is fixed to the back of the display device through the connecting mechanism 11, so that the display device can move together with the fixing member 10, which protects the display device and provides support.

As shown in Figures 2 and 3, the fixing member 10 is provided with a boss 12 along a first direction on the side surface of the fixing member 10 facing away from the display device; the first direction is the adjustment direction of the display device; In the embodiment, the height of the display device can be adjusted in the vertical direction, so the first direction is the vertical direction; and the length direction of the fixing member 10 is set parallel to the first direction, thereby increasing the display device That is, the boss 12 is arranged along the length direction of the fixing member 10, so that the bottom view of the fixing member 10 is convex.

The side surface of the boss 12 facing away from the display device is provided with a sliding groove 14 along a first direction, the opening of the sliding groove 14 is arranged along the first direction, and the opening direction faces away from the display device; this embodiment 3, the sliding groove 14 is a dovetail groove, that is, the cross section of the sliding groove 14 is an inverted trapezoid.

In this embodiment, the sliding groove 14 includes an inner side surface and a bottom surface. The inner side surface of the sliding groove 14 is located on both sides of the opening of the sliding groove 14, and the inner side surface is made of high friction material, so the sliding groove The inner surface of 14 serves as the first friction surface 13.

The side surface of the boss 12 facing away from the display device is provided with a scale along the opening of the sliding groove 14. The scale is also arranged along the first direction, and the scale extends from the opening at one end of the sliding groove 14 to the The chute 14 ends at the opening at the other end, and the scale is used to determine the specific position of the sliding member 20 relative to the fixing member 10. When the height of the display device is adjusted, the position or display of the display device can be quickly determined. The distance adjusted by the equipment; specifically, the scale value starts from the opening at the top of the chute 14 and gradually increases downward along the opening of the chute 14.
