DETAILED DESCRIPTION

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-5As shown, an upper arm assembly of a display stand includes a clamping mechanism, which includes an upper clamping plate 1 and a lower clamping plate 2, the upper clamping plate 1 and the lower clamping plate 2 are connected by bolts, a screw rod 3 is threadedly connected to the lower clamping plate 2, an abutment plate 4 is arranged at the upper end of the screw rod 3, a column 5 is arranged on the upper clamping plate 1, a sleeve 6 is arranged on the column 5, an elastic cushion layer 7 is arranged on the inner surface of the sleeve 6, a fixing block 8 is arranged on one side of the sleeve 6, a cross bar 9 is arranged on one side of the fixing block 8, the fixing block 8 and the cross bar 9 are connected by a hard spring 10, and also includes a rotating cylinder 11, the inner surface of the rotating cylinder 11 is provided with an internal thread, and the outer surface of the fixing block 8 and the outer surface of the cross bar 9 are provided with The internal thread of the rotating drum 11 matches the external thread, and one end of the cross bar 9 is provided with a vertical plate 12, and the upper surface of the vertical plate 12 is provided with a fixed rail 13, and the internal sliding connection of the fixed rail 13 is provided with a slide rod 14, and one end of the fixed rail 13 is provided with a fixing ring 15, and one end of the slide rod 14 is provided with a baffle 16 abutting against the fixing ring 15, and a fastening bolt 17 is threadedly connected to the fixing ring 15, and a through groove for the fastening bolt 17 to pass through is opened on the fixed rail 13, and also includes a connecting seat 18 and a gas spring 19, one end of the slide rod 14 is hinged to the lower end of the connecting seat 18, one end of the gas spring 19 is hinged to the baffle 16, and the other end of the gas spring 19 is hinged to the upper end of the connecting seat 18.

[0019] The material of the cushion layer 7 is rubber or silicone, and the cushion layer 7 is cylindrical. The cushion layer 7 is fixed to the inside of the sleeve 6 by an adhesive. When the sleeve 6 is sleeved on the outer surface of the column 5, the cushion layer 7 is in a compressed state, so that the friction between the cushion layer 7 and the column 5 increases. By controlling the compression degree of the cushion layer 7 and the contact area between the cushion layer 7 and the column 5, the pressure-bearing capacity of the sleeve 6 can be controlled, so that after the connecting seat 18 is installed with the display screen, and when the display screen is extended to the farthest position from the column 5, the sleeve 6 will not move downward on the column 5, and through the friction between the cushion layer 7 and the column 5, the display can be adjusted to a certain angle in the horizontal direction, thereby improving the convenience of angle adjustment in the horizontal direction.

[0020] The hard spring 10 connected to the fixed block 8 and the cross bar 9 plays a supporting role, that is, the cross bar 9, the vertical plate 12, the fixed rail 13, the slide bar 14, the fixed ring 15, the fastening bolt 17, the baffle 16, the gas spring 19, the connecting seat 18 and the display can all exert downward pressure on the hard spring 10. When the hard spring 10 is not bearing weight, it is in a horizontal state. When it is subjected to the pressure of the above-mentioned components, its bending amplitude is small, and the angle between the fixed rail 13 and the desktop is less than 5°. At the same time, when a foreign object collides with the display, the force is transmitted to the hard spring 10 through the connecting seat 18. The hard spring 10 can change the position of the display through its own deformation to reduce damage to the display.

[0021] In order to further improve the stability of the display, an auxiliary block 21 is provided on the outer surface of the sleeve 6 and above the fixed block 8. The auxiliary block 21 is located on one side of the fixed rail 13. The auxiliary block 21 and the fixed rail 13 are connected by a hard spring 10 to improve the torsion resistance of the hard spring 10.

[0022] When the distance between the display and the user needs to be adjusted, the display is first fixed on the connecting base 18, and then the display drives the connecting base 18 to move, and the connecting base 18 drives the sliding bar 14 to move, and the position of the sliding bar 14 in the fixed rail 13 changes, thereby controlling the distance between the display and the user. After completing the above adjustment, the fastening bolt 17 is rotated to increase the friction between the fastening bolt 17 and the sliding bar 14 to prevent the sliding bar 14 from continuing to move in the fixed rail 13.

[0023] When the angle of the display needs to be adjusted, the angle of the display can be adjusted by controlling the extension and retraction of the gas spring 19 .

[0024] Furthermore, it also includes a protective shell 20, which is arranged on the outer surface of the fixing ring 15, and the gas spring 19 is located inside the protective shell 20. The protective shell 20 is used to protect the gas spring 19 to prevent the gas spring 19 from being impacted by lateral force and affecting its air tightness.

[0025] Furthermore, the lower surface of the slide bar 14 is configured to be a matte surface, so as to increase the friction between the slide bar 14 and the fastening bolt 17 .

[0026] Furthermore, grooves are evenly arranged on the outer surface of the drum 11 to increase the friction between the outer surface of the drum 11 and the outer surface of the drum 11 .

[0027] Working principle: When installing the display, firstly, the two ends of the rotating drum 11 are threadedly connected to the cross bar 9 and the fixing block 8 respectively, and then the display is installed on the connecting seat 18, and then the inclination angle of the display is adjusted. After the angle adjustment is completed, the sleeve 6 is moved on the column 5, and the friction between the cushion layer 7 and the column 5 is used to make the sleeve 6 stop on the column 5, thereby realizing the height adjustment of the display, and then the position of the display on the horizontal plane is adjusted by rotating the sleeve 6, and then the slide bar 14 is driven by the display to move in the fixed rail 13 to adjust the distance between the display and the user. After the distance adjustment is completed, the friction between the fastening bolt 17 and the slide bar 14 is increased by tightening the fastening bolt 17, so that the position of the slide bar 14 is fixed. After completing the above adjustment, the rotating drum 11 is screwed in the direction close to the cross bar 9 to completely disengage the rotating drum 11 from the fixing block 8, thereby completing the adjustment of the display.

[0028] When the display in the device is hit by a collision, the fixing of the slide bar 14 by the fastening bolts 17 and the deformation of the hard spring 10 can effectively reduce the impact of the collision on the distance between the display and the user and the height of the display, while reducing the damage to the display caused by the collision. When restoring the position of the display, it is only necessary to adjust the horizontal position and the tilt angle of the display, and only two dimensions need to be adjusted, thereby improving the convenience and speed of adjustment.

[0029] 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.
