It is fixedly connected with the column 1 to drive it to rotate in the horizontal direction. It is characterized in that: the top of the central column 10 is provided with a square protrusion 11 with a round hole in the middle; The square protrusion 11 engages; the shaft screw 5 passes through the anti-rotation washer 4 and the central hole 12 in turn, and then is threadedly connected with the central column 10 of the chassis 2 to limit the movement of the turntable 3 in the vertical direction.

A nylon rotary sleeve 6 is arranged between the central column 10 and the central hole 12 .

A nylon washer 8 is arranged between the turntable 3 and the chassis 2 .

The anti-rotation washer 4 is circular.

Several rubber pads 9 are arranged on the bottom of the chassis 2 .

The rubber pad 9 is arranged on the edge.

The utility model has the following beneficial effects and advantages:

1. There are anti-rotation washers between the chassis shaft and the turntable and the shaft screws, and the anti-rotation washers will not rotate with the rotation of the turntable. It ensures that the base rotates for a long time, and the shaft screws will not loosen.

2. There is a nylon sleeve between the center hole of the turntable and the chassis shaft. Nylon has excellent wear resistance and damping feel. Nylon washers are added between the rotating plane of the turntable and the rotating plane of the chassis, which improves the use feeling and prolongs the service life.

3. The column and the turntable are fixed together by the support, and the monitor is fixed on the column. When a proper force is applied to touch the display in the direction perpendicular to the plane of the display, the display can rotate left and right smoothly along with the main body of the column and the turntable.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

As shown in Figures 1 to 4, the utility model is mainly composed of a column 1, a chassis 2, a turntable 3, a stop washer 4, a shaft screw 5, a nylon sleeve 6, a support member 7, a nylon washer 8 and a rubber pad from a structural point of view. 9 composition.

1) Column 1: The display is installed on the top, and the other end is installed on the turntable 3, which is used as a supporting column connected with the display.

2) Chassis 2: Assembled with the turntable 3 through the central column 10, and kept relatively fixed with the desktop. It is used as a base for the rotation of the turntable 3 and the display, and a rubber pad 9 is pasted on the bottom surface to maintain the stability of the rotation of the base.

3) Turntable 3: The central hole 12 is set on the central column 10 of the chassis 2, which can rotate around the rotation axis of the chassis 2 and is fixed with the column 1 at the same time.

4) Anti-rotation washer 4: Assembled between the chassis 2 and the shaft screw 5 to prevent the rotation and loosening of the shaft screw 5.

5) Rotary shaft screw 5: the rotary shaft screw 5 is driven into the center column 10 of the chassis 2 to limit the movement of the turntable 3 in the vertical direction so that the turntable 3 can only rotate horizontally around the chassis 2.

6) Nylon rotating sleeve 6: assembled in the gap between the central hole 12 and the central column 10, and plays the role of adjusting the rotation damping effect.

7) Support 7: Fix the column 1 and the turntable 3 together.

8) Nylon washer 8: Assembled on the plane between the turntable 3 and the chassis 2, it plays the role of avoiding metal friction between the turntable 3 and the chassis 2 and adjusting the magnitude of the rotational force.

9) Rubber pad 9: increase the friction between the chassis and the table top to prevent the chassis 2 from moving.

The central hole 12 of the turntable 3 is inserted into the center column 10 of the chassis 2, and the vertical movement of the turntable 3 is restricted by the shaft screw 5 and the anti-rotation washer 4, so that the turntable 3 can only rotate horizontally around the chassis 2, while the turntable 3 Between the central hole 12 and the central column 10, between the rotation plane of the turntable 3 and the rotation plane of the chassis 2, the feel of the rotation is adjusted through the nylon swivel 6 and the nylon washer 8 . The column 1 is fixed on the turntable 3 through the support 7 , and the display is fixed on the column 1 . The rubber pad 9 is pasted on the bottom of the chassis 2, which increases the friction between the chassis 2 and the desktop. Therefore, when a proper force is applied to touch the display in the vertical direction of the display plane, the display can rotate left and right along with the column 1 and the turntable 2 smoothly.
