DETAILED DESCRIPTION

The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

As shown in Fig. 1-4, a double-arm aluminum alloy computer monitor stand comprises a card slot 1, an adjusting screw 2 is threadedly connected to the card slot 1, an abutment block 3 is arranged at the end of the adjusting screw 2, the abutment block 3 is located inside the card slot 1, a column 4 is arranged on the upper surface of the card slot 1, a sliding sleeve 5 is arranged on the column 4, the sliding sleeve 5 and the column 4 are connected by a positioning bolt 6, a curved rod 7 is arranged on the outer surface of the sliding sleeve 5, a sleeve 8 is arranged at the upper end of the curved rod 7, a vertically arranged bevel gear 9 is symmetrically arranged inside the sleeve 8, and the upper and lower ends of the sleeve 8 are respectively rotated A center rod 10 is dynamically connected, and a horizontally arranged bevel gear 9 is respectively provided at one end of the two center rods 10 that are close to each other. The bevel gear 9 on the center rod 10 is externally meshed with two vertically arranged bevel gears 9. Extension plates 11 are respectively provided at two ends of the two center rods 10 that are away from each other, and curved support arms 12 are respectively provided at the ends of the two extension plates 11. Extension rods 13 are respectively provided at the ends of the two support arms 12. The two extension rods 13 are at the same horizontal height, and a base 14 connected to a computer monitor 17 is provided at the end of the extension rod 13.

The card slot 1 is composed of two L-shaped metal plates of different sizes, wherein the small L-shaped metal plate can move up and down inside the large L-shaped metal plate, and the two L-shaped metal plates can be fixed together by bolts, so that the internal height of the card slot 1 can be adjusted according to the thickness of the desktop of the computer desk, and then the upper surface of the abutment block 3 is abutted against the lower surface of the computer desk by rotating the adjusting bolt, thereby completing the fixation of the card slot 1. In the card slot 1 and the abutment block 3, all positions that can contact the computer desk can be provided with a compressible cushion layer, and the material of the cushion layer can be rubber or plastic, thereby improving the installation stability of the card slot 1 on the computer desk.

The interior of the column 4 is hollow, and an array of limit holes 15 are provided on the outer surface of the column 4. The positioning bolts 6 are threadedly connected to the column 4 through the limit holes 15. When the height of the computer display 17 needs to be adjusted, the sliding sleeve 5 can be moved on the column 4, so that the height of the computer display 17 can be adjusted. When it is adjusted to a suitable position, the sliding sleeve 5 is moved to the position of the limit hole 15 closest to the positioning screw, and then the positioning bolts 6 are passed through the limit holes 15 on the column 4, so that the sliding sleeve 5 is fixed on the column 4. The positioning bolts 6 can also increase the friction between the two by squeezing the outer surface of the column 4, so as to fix the position of the sliding sleeve 5, and the upper end of the sliding sleeve 5 abuts against the lower end of one of the center rods 10, so as to support the center rod 10 located below, thereby reducing the supporting pressure of the curved rod 7 and preventing the curved rod 7 from bending due to long-term stress. At the same time, when carrying the device, it can be grasped by directly grasping the curved rod 7, which is convenient to carry.

Both ends of the sleeve 8 are respectively provided with inwardly bent edges, and the outer surface of the center rod 10 is provided with an anti-slip block 16 abutting against the folded edge. The anti-slip block 16 is made of rubber material, and the minimum diameter of the anti-slip block 16 near the end of the bevel gear 9 is smaller than the minimum diameter of the sleeve 8 at the folded edge. During installation, one end of the center rod 10 and the anti-slip block 16 are completely inserted into the sleeve 8 by extrusion. After entering the sleeve 8, the anti-slip block 16 has a tendency to return to its original state, so that the horizontally arranged bevel gear 9 on the center rod 10 can maintain a tight external meshing with the vertically arranged bevel gear 9 in the cylinder body, thereby preventing the bevel gear 9 from loosening and causing loud noise.

The extension plate 11, the support arm 12 and the extension rod 13 can only rotate on the horizontal plane, and the base 14 can only rotate on the vertical plane. The horizontal plane and the vertical plane both use the desktop of the computer desk as the reference plane. The horizontal plane is parallel to the desktop of the computer desk, and the vertical plane is perpendicular to the desktop of the computer desk. Among the extension plate 11, the support arm 12 and the extension rod 13, the support arm 12 is the longest. When adjusting the position of the center rod 10, the rotation of the center rod 10 can be controlled by controlling the movement of the support arm 12, and the rotation of the center rod 10 can be easily and stably controlled. The connection points of the joints of the extension plate 11, the support arm 12, the extension rod 13 and the base 14 can be fixed by bolts. When adjustment is needed, the bolts can be loosened, and when the adjustment is completed, the bolts can be tightened.

Working principle: First, install two computer monitors 17 on two bases 14 respectively, and then control one of the arms 12 to swing, and drive the extension plate 11 and the center rod 10 connected to the extension plate 11 to rotate through the arm 12. During the rotation of the center rod 10, the bevel gear 9 in the sleeve 8 is transmitted, so that the two center rods 10 can rotate at the same time. At the same time, the rotation directions of the two center rods 10 are opposite, so that the positions of the two arms 12 can be adjusted at the same time, and the adjustment of the arms 12 is convenient and accurate. After completing the adjustment of the arms 12, the extension rod 13 is controlled to rotate through the computer monitor 17, and the two computer monitors 17 are aligned and form a certain angle.

The device can control the rotation of one of the arms 12 so that the two arms 12 swing simultaneously, and can quickly adjust the distance between the two bases 14 to adapt to the size of the computer display 17 and improve the adjustment efficiency of the position of the base 14. At the same time, through the transmission of the bevel gear 9, the positions of the two arms 12 are kept in a relatively symmetrical state, which is conducive to maintaining the balance of the display stand and preventing skewing due to uneven force.

In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
