Utility model content

The purpose of the present invention is to provide a subject to solve the problems raised in the above-mentioned background art.

To achieve the above object, the utility model provides the following technical solutions:

An adjustable computer stand includes a base and a motor. A circular hole is longitudinally opened in the middle of the base, and a cylindrical rotating seat is placed in the hole. The rotating seat can rotate in the base. The upper surface of the rotating seat is provided with a switch, and the switch can control the switch and the rotation direction of the motor. . A clamping ring is arranged in the base at the contact point with the rotating seat, and the clamping ring is a rack-like structure. The outer side wall of the rotating seat is provided with a plurality of grooves, and a clamping block with a V-shaped structure is placed in the groove, and the clamping block is made of elastic metal material. When the rotating base is rotated, the clamp ring presses the block inward, and the block opens and compresses in the groove. When the rotation stops, the clamping block resumes its deformation and is stuck on the collar, so that the rotating seat is clamped tightly.

A motor is fixed at the center of the rotating seat, and a vertical lifting rod is rotatably connected to the output shaft of the motor. Driven by the motor, the lift rod rotates coaxially with the output shaft of the motor. A thread is provided on the lift rod. A lift seat is nested on the lift rod, and the lift seat is a cylindrical structure with threads arranged inside. The two sides of the motor are fixed with vertical limit rods on the upper surface of the rotating base, and the top of the limit rod is fixed with a horizontal limit block. The setting of the limit block is convenient to control the height of the lifting seat and prevent the lifting seat from exceeding the height of the lifting rod. The side surface of the lifting seat is provided with a vertical clamping slot, and the restriction rod penetrates the clamping slot. The setting of the limit rod and the card slot prevents the lift seat from rotating with the lift rod. When the lifting rod rotates, the lifting seat is moved up and down with the rotation of the lifting rod because the limiting rod and the clamping groove limit the rotation of the lifting seat.

The right side of the lift seat is hinged with one end of the third hinge rod, the other end of the third hinge rod is hinged with one end of the second hinge rod, the other end of the second hinge rod is hinged with one end of the first hinge rod, and the second hinge rod is hinged with one end of the first hinge rod. The other end of a hinge rod is hinged with the universal seat, and the other end of the universal seat is fixed on the left side of the display screen. The universal seat can be rotated in all directions within a certain range to adjust the angle of the display screen. By applying a pulling force or a pushing force to the display screen, the first hinge rod, the second hinge rod and the third hinge rod can rotate relative to each other to extend or overlap, thereby adjusting the front and rear positions of the display screen.

As a further solution of the present invention, several rotating protrusions are evenly fixed on the upper surface of the rotating seat, and the rotating protrusions are arranged to facilitate the rotation of the rotating seat.

As a further solution of the present utility model: the cross section of the groove is a convex-shaped structure.

As a further solution of the present utility model: the clip ring has a smooth wave-like structure.

As a further scheme of the present invention, arc-shaped shrapnel is placed in the groove, the shrapnel is made of elastic metal material, the top of the shrapnel is fixed with a top post, and the other end of the top post is fixed with a hemispherical top cap. When the rotating seat rotates, the collar presses the top cap inward, so that the shrapnel opens and compresses, and the top cap moves inward. When the rotating seat stops rotating, the shrapnel recovers its deformation, so that the top cap moves outward and is stuck on the collar, so that the rotating seat is clamped tightly.

Compared with the prior art, the beneficial effect of the utility model is that the display screen can be rotated in any direction within a certain range by using the universal seat, which makes the adjustment of the display screen more convenient. Using a plurality of hinge rods to connect the display screen, the display screen can be controlled at will within a certain range in the front and rear directions, the movement range is large, and the operation is convenient. Use the motor to control the display up and down. It avoids the need to manually move the display screen and reduces the workload of personnel. Use the rotating base to adjust the rotation of the display screen to meet the 360° rotation of the display screen in the horizontal direction. The device has the advantages of simple structure, easy operation, large adjustment range and convenient and quick adjustment.
