In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] In this embodiment, a ventilator display device (not shown) is provided, including a rotating mechanism and a display.

[0036] Among them, combined Figure 1-9 The rotating mechanism includes a sleeve 1, an arm 2 and a fixed block 3, the arm 2 includes a first section 21 and a second section 22 connected to the first section 21; a first damping structure 4 connected to the first section 21 of the arm 2 is provided in the sleeve 1, and the arm 2 rotates around the axis of the sleeve 1 through the first damping structure 4; the second section 22 of the arm 2 extends radially outward from the sleeve 1, and a clamping opening 222 with adjustable width is formed at the end position of the second section 22 away from the first section 21, and a second damping structure 5 connected to the fixed block 3 is provided in the clamping opening 222, and the fixed block 3 rotates around the second section 22 in the clamping opening 222 through the second damping structure 5, and the rotating shaft 31 of the fixed block 3 is perpendicular to the central axis of the sleeve 1 and the extension direction of the second section 22; the display is fixed to the fixed block 3.

[0037] The display can be assembled on the fixed block 3, and the first section 21 of the support arm 2 can rotate relative to the sleeve 1 around the axis through the first damping structure 4, so that the display can be rotated left and right, and because of the effect of the first damping structure 4, the angle of the display can be stably maintained after being rotated left and right; the fixed block 3 can rotate relative to the second section 22 in the clamping opening 222 through the second damping structure 5, so that the display can be rotated up and down, and after adjusting the up and down angles of the display, the width of the clamping opening 222 can be reduced, so that the second damping structure 5 can be clamped to provide greater damping, so that the corresponding angle of the display in the pitch direction can be stably fixed. Both left and right rotation and pitch rotation can be achieved, and the angle can be reliably maintained after the pitch rotation, which is convenient for users to use.

[0038] Furthermore, combined with Figure 3 , 5 -8, an elastic wall 221 is provided on the top side or the bottom side of the second section 22, a clamping opening 222 is formed between the elastic wall 221 and the second section 22, and the support arm 2 also includes an adjusting member 223 connected to the elastic wall 221 and the second section 22, and the adjusting member 223 is used to adjust the distance between the elastic wall 221 and the second section 22.

[0039] Specifically, in the present embodiment, the support arm 2 is die-cast, and the specific material is ADC12, also known as No. 12 aluminum material, which has the characteristics of light structure and low cost; the elastic wall 221 is connected to the bottom side of the second section 22 and is bent toward the first section 21, so that the clamping port 222 can be located in a relatively hidden position, which is safer and more reliable. The clamping port 222 includes an axial hole and an adjustment notch connecting the radial position of the axial hole, and the adjustment notch is located at the end position of the elastic wall 221. The adjustment member 223 is connected to the second section 22 after passing through the end position of the elastic wall 221 and the adjustment notch. The adjustment member 223 adopts an M6*16 hexagonal screw with a gasket; the fixed block 3 includes a rotating shaft 31 passing through the axial hole, and the second damping structure 5 is arranged between the hole wall of the axial hole and the rotating shaft 31. The rotating shaft 31 is locked to the fixed block 3 by two M4*10 hexagonal screws (with gaskets). By adjusting the adjusting member 223, the spacing between the elastic wall 221 and the second section 22 can be adjusted, thereby changing the clamping force of the shaft hole in the radial direction and changing the rotation damping of the rotating shaft 31. In this way, when it is necessary to easily adjust the pitch angle of the display, the adjusting member 223 can be rotated to loosen the clamping opening 222. After the adjustment is completed, the adjusting member 223 can be rotated again to narrow the clamping opening 222 so as to clamp it. The adjustment method is convenient and fast, and the angle can be stably maintained after adjustment. In some embodiments, the elastic wall 221 can also be set on the top side of the second section 22. In some embodiments, the adjusting member 223 can also adopt other types of studs and other structures, as long as it can achieve the adjustment of the spacing between the elastic wall 221 and the second section 22, which is not limited here.

[0040] Furthermore, the second damping structure 5 includes two damping sleeves respectively embedded in the shaft hole from both ends of the shaft hole, the fixed block 3 includes connecting seats 32 arranged opposite to each other and having a gap, the end of the second section 22 is located in the gap, and the rotating shaft 31 is fixed between the two connecting seats 32 and penetrated in the two damping sleeves. Specifically, the damping sleeve is made of H62 material (brass material), which is open-loop, and has an extension edge at the end, and the extension edge is located between the side wall of the second section 22 and the corresponding side wall of the connecting seat 32. In this way, when the width of the clamping opening 222 changes, the shape of the damping sleeve can be adaptively deformed, thereby providing damping for the fixed block 3, and the life of the damping sleeve can provide the fixed block 3 with 7300 pitch swings.

[0041] Furthermore, the fixed block 3 is provided with limiting surfaces in both directions of rotation around the second section 22, and the second section 22 is provided with a limiting structure 224 that can respectively abut against the two limiting surfaces to limit the rotation range of the fixed block 3 around the second section 22. Specifically, in the present embodiment, a limiting groove located between the two connecting seats 32 is provided on one side of the fixed block 3 close to the second section 22, and the limiting structure 224 is a limiting block protrudingly arranged at the end of the second section 22, and the limiting block extends into the limiting groove, so that the upper and lower side surfaces of the limiting groove constitute the first limiting surface and the second limiting surface, and in the process of the fixed block 3 rotating up and down, the first limiting surface and the second limiting surface will abut against the limiting block, thereby limiting the angle of the fixed block 3 rotating downward and transmitting upward, so that when the fixed block 3 is installed with a display, the display can only swing up and down within a predetermined angle, and it should be understood that the predetermined angle can be adaptively adjusted according to actual conditions. In some embodiments, the first limiting surface and the second limiting surface may also be arranged in other forms. For example, a limiting block is arranged on one side of the fixed block 3, and the limiting structure 224 is a limiting groove arranged on the second section 22, and the limiting block extends into the limiting groove. In this way, the upper and lower side surfaces of the limiting block serve as the first limiting surface and the second limiting surface, and can also realize the limitation of the pitch angle of the fixed block 3.

[0042] Furthermore, combined with Figure 1-3 The rotating mechanism also includes a first fixing plate 6 fixed to the fixing block 3 and a second fixing plate 7 fixed to one side of the first fixing plate 6, and a clamping gap for assembling the fixed parts is formed between the first fixing plate 6 and the second fixing plate 7.

[0043] Furthermore, combined with Figure 4 , 8 -10, a partition 11 with a through hole is arranged in the sleeve 1 to divide its internal space into a top cavity and a bottom cavity, the first section 21 includes a rotating column 211 rotatably connected to the top cavity and a damping column 212 connected to the rotating column 211 and passing through the through hole to the bottom cavity, and the first damping structure 4 is arranged in the bottom cavity and assembled with the damping column 212.

[0044] Furthermore, a first isolation sleeve 12 is fitted on the wall of the top cavity, a second isolation sleeve 13 is fitted on the wall of the through hole, and a plurality of sealing rings 213 that are interference fit with the first isolation sleeve 12 are provided on the outside of the rotating column 211; the partition 11 is provided with a limiting column 111 located in the top cavity, and an abutment block 2111 is provided at the bottom of the rotating column 211, and the limiting column 111 is on the rotation path of the abutment block 2111.

[0045] Specifically, in the present embodiment, the top sides of the first isolation sleeve 12 and the second isolation sleeve 13 both have an extended edge extending outward, the first isolation sleeve 12 matches the top cavity, the second isolation sleeve 13 matches the through hole of the partition 11, the limiting column 111 is an M4*10 hexagon socket screw (with a gasket) fixed to the partition 11, and after the limiting column 111 is fixed, the first isolation sleeve 12 and the second isolation sleeve 13 are pressed into the top cavity and the through hole respectively by a hydraulic press, so that the extended edge of the first isolation sleeve 12 fits against the top side of the sleeve 1, and the extended edge of the second isolation sleeve 13 fits against the top side of the partition 11, and when the first section 21 is assembled on When in the sleeve 1, the shoulder of the first section 21 abuts against the top side of the extended edge of the first isolation sleeve 12, and the bottom end of the rotating column 211 abuts against the top side of the extended edge of the second isolation sleeve 13. A sealing ring 213 is arranged between the rotating column 211 and the first isolation sleeve 12 and lubricating oil is applied. The arrangement of the first isolation sleeve 12 and the second isolation sleeve 13 can make the rotation between the support arm 2 and the sleeve 1 more stable and reliable, smooth and without scratches, and the arrangement of the limiting column 111 and the abutment block 2111 can limit the rotation angle of the support arm 2 relative to the sleeve 1, which is equivalent to limiting the left and right rotation of the display within a preset angle range.

[0046] Furthermore, the first damping structure 4 includes a first friction plate 41, a second friction plate 42, a first butterfly gasket 43, a second butterfly gasket 44, which are stacked in sequence from the partition 11 toward the bottom cavity and sleeved on the damping column 212, and a pressure block 45 fixed to the end of the damping column 212. The first friction plate 41 is fixed to the sleeve 1 in the circumferential direction, the first butterfly gasket 43 and the second butterfly gasket 44 are in opposite directions, and the pressure block 45 is pressed against the bottom side of the second butterfly gasket 44.

[0047] Specifically, in the present embodiment, a protrusion is provided around the first friction plate 41, and a groove matching the protrusion is provided on the side wall of the bottom cavity. When the first friction plate 41 is sleeved on the damping column 212, the protrusion of the first friction plate 41 is embedded in the groove. In this way, the first friction plate 41 will not rotate relative to the sleeve 1. Since the first butterfly gasket 43 and the second butterfly gasket 44 are in opposite directions, the first butterfly gasket 43 and the second butterfly gasket 44 will provide elastic force when under pressure. The pressing block 45 is fixed to the end of the damping column 212 by two M5*16 hexagon socket screws, thereby the first The friction plate 41, the second friction plate 42, the first butterfly gasket 43 and the second butterfly gasket 44 are pressed against the bottom side of the partition 11, so that the elastic force provided by the first butterfly gasket 43 and the second butterfly gasket 44 can make the first friction plate 41 and the second friction plate 42 stick together to generate damping. The second damping structure 5 in the present application has the advantages of low cost, small thickness and adjustable damping, and the support arm 2 rotates smoothly and reliably relative to the sleeve 1, and can stop at any angle within the rotatable range, and the angle can be fixed after the left and right rotation angle adjustment is completed, which is easy to use.
