Detailed Implementation

[0026] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0027] The core of this invention is to provide an orientation flip adjustment mechanism, a monitor stand, and an adjustment method. This embodiment utilizes air pressure to drive a rubber ring to provide a locking structural friction force, and utilizes air pressure difference to provide a locking structural adsorption force, so as to achieve 360-degree unlimited position adjustment of the monitor stand.

[0028] This embodiment provides a monitor stand. Figure 1 This is a schematic diagram of a monitor stand according to an embodiment of the present invention, as shown below. Figure 1 As shown, this embodiment of a monitor stand includes a support base A and an orientation tilt adjustment mechanism B.

[0029] Specifically, Figure 2 This is a schematic diagram of a monitor stand according to an embodiment of the present invention, as shown below. Figure 2 As shown, in this embodiment, the support base A includes a support base plate A01, and a support column A02 is fixedly installed on the upper end surface of the support base plate A01; the orientation flipping adjustment mechanism B includes a rotating adjustment cylinder B01, which is rotatably sleeved on the outside of the support column A02, and there is a gap between the inner wall of the rotating adjustment cylinder B01 and the cylindrical surface of the support column A02. The rotating adjustment cylinder B01 is used for orientation flipping adjustment, and orientation flipping is achieved by rotating the rotating adjustment cylinder B01 around the support column A02.

[0030] Specifically, in this embodiment, Figure 3 , Figure 4 This is a partial cross-sectional schematic diagram of a display bracket according to an embodiment of the present invention, as shown below.Figure 3 and Figure 4 As shown, the rotating adjusting cylinder B01 has a cavity B01-1 inside its wall structure. A movable structural ring B01-2 is movably installed inside cavity B01-1. The movable structural ring B01-2 horizontally divides cavity B01-1 into an upper cavity B01-11 and a lower cavity B01-12. The movable structural ring B01-2 slides up and down within cavity B01-1 to change the volume and internal air pressure of the upper cavity B01-11 and lower cavity B01-12, i.e., the movable structural ring... When the movable ring B01-2 moves upward within cavity B01-1, the volume of the upper cavity B01-11 is compressed and decreases while the internal air pressure increases, and the internal volume of the lower cavity B01-12 expands and increases while the internal air pressure decreases. When the movable ring B01-2 moves downward within cavity B01-1, the volume of the lower cavity B01-12 is compressed and decreases while the internal air pressure increases, and the internal volume of the upper cavity B01-11 expands and increases while the internal air pressure decreases.

[0031] in, Figure 5 This is a partial structural diagram of a monitor stand according to an embodiment of the present invention, as shown below. Figure 5 As shown, in this embodiment, the upper end of the inner wall of the rotating adjusting cylinder B01 is also provided with several sets of elastic hollow rubber rings B01-3. The hollow cavities inside the several sets of elastic hollow rubber rings B01-3 are all connected to the upper cavity B01-11. When the internal air pressure of the upper cavity B01-11 increases, it drives the several sets of elastic hollow rubber rings B01-3 to elastically expand and abut against the cylindrical surface of the internal support column A02 of the rotating adjusting cylinder B01. When the internal air pressure of the upper cavity B01-11 decreases, it drives the several sets of elastic hollow rubber rings B01-3 to elastically contract and disengage from the cylindrical surface of the internal support column A02 of the rotating adjusting cylinder B01. It should be noted that there is a gap between the inner wall of the rotating adjusting cylinder B01 and the cylindrical surface of the support column A02. The gap is such that when several sets of elastic hollow rubber rings B01-3 elastically expand, the expansion amount of several sets of elastic hollow rubber rings B01-3 is greater than the gap between the inner wall of the rotating adjusting cylinder B01 and the cylindrical surface of the support column A02, so that they can abut against the cylindrical surface of the support column A02 inside the rotating adjusting cylinder B01 through expansion. At the same time, when several sets of elastic hollow rubber rings B01-3 elastically contract, the gap between the inner wall of the rotating adjusting cylinder B01 and the cylindrical surface of the support column A02 allows several sets of elastic hollow rubber rings B01-3 to disengage from the cylindrical surface of the support column A02 inside the rotating adjusting cylinder B01, that is, several sets of elastic hollow rubber rings B01-3 can disengage from the cylindrical surface of the support column A02 inside the rotating adjusting cylinder B01.

[0032] Figure 6 This is a partial structural diagram of a monitor stand according to an embodiment of the present invention, as shown below. Figure 6As shown, in the embodiment, a rotating sliding groove A01-1 is further formed on the support bottom plate A01, the lower end of the cylinder wall of the rotating adjusting cylinder B01 is located in the rotating sliding groove A01-1, and the lower end surface of the cylinder wall of the rotating adjusting cylinder B01 is in sliding contact with the inner bottom surface of the rotating sliding groove A01-1. It should be noted that the size of the slot opening of the rotating sliding groove A01-1 matches the size of the lower end of the cylinder wall of the rotating adjusting cylinder B01, so that the rotating adjusting cylinder B01 is movably clamped in the rotating sliding groove A01-1 through the lower end of the cylinder wall, thereby reducing the deviation displacement of the rotating adjusting cylinder B01 during rotation. In order to improve the contact between the lower end surface of the cylinder wall of the rotating adjusting cylinder B01 and the inner bottom surface of the rotating sliding groove A01-1, a person skilled in the art can also provide lubricating oil to improve the contact and sealing.

[0033] Specifically, please continue to refer to Figure 3 In the embodiment, the lower end surface of the cylinder wall of the rotating adjusting cylinder B01 is further provided with a cavity opening B01-4, the cavity opening B01-4 is in communication with the lower cavity B01-12 and closely contacts the inner bottom surface of the rotating sliding groove A01-1. When the internal pressure of the lower cavity B01-12 decreases, the rotating adjusting cylinder B01 is adsorbed in the rotating sliding groove A01-1 through the lower cavity B01-12. When the internal pressure of the lower cavity B01-12 increases, the rotating adjusting cylinder B01 is separated from the adsorption between the rotating sliding groove A01-1. It should be noted that in order to realize the adsorption between the rotating adjusting cylinder B01 and the rotating sliding groove A01-1, when the movable structure ring B01-2 is located at the middle of the cavity B01-1, that is, the cavity volumes of the upper cavity B01-11 and the lower cavity B01-12 are equal, the internal pressure of the upper cavity B01-11 and the lower cavity B01-12 is the same as the external atmospheric pressure. At this time, when the movable structure ring B01-2 is further moved upward to expand the internal volume of the lower cavity B01-12 and increase the internal pressure, that is, the internal pressure of the lower cavity B01-12 is lower than the external atmospheric pressure, that is, under the action of the external atmospheric pressure, the adsorption between the rotating adjusting cylinder B01 and the rotating sliding groove A01-1 is realized.

[0034] Specifically, in the embodiment, please continue to refer to Figure 2 The azimuthal flip adjusting mechanism B further comprises a mounting rack B02, which is fixedly connected to the upper end of the rotating adjusting cylinder B01, and the mounting rack B02 is used for mounting a display.

[0035] Specifically, in the embodiment, Figure 7 The structure of the display support according to the embodiment of the application is shown in FIG. 1. Figure 7As shown, the outer side of the rotating adjusting cylinder B01 is also provided with a movable groove B01-5, the movable structure ring B01-2 is fixedly connected with an operation handle B01-21, the operation handle B01-21 extends out of the movable groove B01-5, and the operation handle B01-21 is located in the movable groove B01-5.

[0036] The movable groove B01-5 includes a displacement groove B01-51 and two limiting grooves B01-52, and the two limiting grooves B01-52 are respectively located at the upper and lower ends of the displacement groove B01-51. It should be noted that, in this embodiment, since the movable structure ring B01-2 is movable up and down, the displacement groove B01-51 is in a vertical direction, and the two limiting grooves B01-52 are both in a horizontal direction. In order to prevent the movable groove B01-5 from causing the internal air pressure of the cavity B01-1 to leak, the operation handle B01-21 is located at the middle position of the vertical structure of the movable structure ring B01-2, and the length of the displacement groove B01-51 is less than half the length of the vertical structure of the movable structure ring B01-2, that is, the movable structure ring B01-2 always seals the opening of the movable groove B01-5 by its own structure.

[0037] In another aspect, the embodiment also provides a position flip adjustment method, which uses the display support according to the above description. The position flip adjustment method specifically includes the following steps.

[0038] When the position flip adjustment is performed, the operation handle B01-21 is moved from the upper end to the lower end of the displacement groove B01-51, and the operation handle B01-21 is clamped in the limiting groove B01-52 at the lower end of the displacement groove B01-51. At this time, the movable structure ring B01-2 inside the cavity B01-1 moves downward, the internal air pressure of the upper cavity B01-11 decreases, the internal air pressure of the lower cavity B01-12 increases, the elastic hollow rubber ring B01-3 is driven to shrink and separate from the cylindrical surface of the support column A02 inside the rotating adjusting cylinder B01, and the rotating adjusting cylinder B01 and the rotating sliding groove A01-1 are separated. At this time, the rotating adjusting cylinder B01 can be rotated according to the requirement, and the position flip adjustment is completed.

[0039] When the position flip adjustment is performed, the operation handle B01-21 is moved from the upper end to the lower end of the displacement groove B01-51, and the operation handle B01-21 is clamped in the limiting groove B01-52 at the lower end of the displacement groove B01-51. At this time, the movable structure ring B01-2 inside the cavity B01-1 moves downward, the internal air pressure of the upper cavity B01-11 decreases, the internal air pressure of the lower cavity B01-12 increases, the elastic hollow rubber ring B01-3 is driven to shrink and separate from the cylindrical surface of the support column A02 inside the rotating adjusting cylinder B01, and the rotating adjusting cylinder B01 and the rotating sliding groove A01-1 are separated. At this time, the rotating adjusting cylinder B01 can be rotated according to the requirement, and the position flip adjustment is completed.

[0040] The foregoing merely illustrates the principles of the application and application of its more prominent features. Those skilled in the art will appreciate that the application is not limited to the embodiments described above, but rather that various changes and modifications can be made thereto without departing from the spirit and scope of the application.
