[0002] With the improvement of science and technology and living standards, monitors are being used more and more widely in production and daily life. In order to meet the needs of adjusting the angle and orientation of monitors, a variety of monitor stands have appeared on the market.

[0003] In existing technologies, monitor stands typically use a screw to move a threaded slider, which in turn moves a gas spring within a spring arm at different angles and / or lengths to achieve a balance of different force values. Because the gas spring has a relatively large force, rotating the screw requires a significant amount of force. Furthermore, the screw is usually axially pressed into the spring arm by a nut, causing it to abut against the housing and / or the end face of the nut. This can easily lead to a large friction area between the housing and / or the nut and the screw, resulting in high resistance to screw rotation and a poor user experience. Utility Model Content

Detailed Implementation

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 6 As shown, an embodiment of this utility model provides a cantilever device. The cantilever device includes: a cantilever assembly, including a housing 10, an elastic member 20, and an anti-detachment member 12. The housing 10 is provided with a mounting hole 11, and the anti-detachment member 12 is installed at the opening of the mounting hole 11; an adjustment assembly, including a screwing member 30 and an axial bearing member 40. The screwing member 30 is rotatably installed in the mounting hole 11 and is pressed and limited by the anti-detachment member 12 along the rotation axis of the screwing member 30. The screwing member 30 and the elastic member 20 are arranged at an angle. The first end of the elastic member 20 is connected to the housing 10, and the second end of the elastic member 20 is linked with the screwing member 30. When the screwing member 30 is screwed, the second end moves on the screwing member 30 to extend or retract the elastic member 20; wherein, at least one of the housing 10 and the anti-detachment member 12 is in rolling engagement with the screwing member 30 through the axial bearing member 40, and the axial bearing member 40 is capable of bearing and transmitting axial force.

[0027] In the above technical solution, by rotating the rotating member 30, the user can cause the second end of the elastic member 20 to change its position on the rotating member 30, thereby changing the extension or contraction state of the elastic member 20 and adjusting the support force. This ensures that the display can be stably suspended in any position, providing the user with a comfortable and efficient user experience. During this movement, the anti-detachment member 12 can press and limit the rotating member 30 to prevent it from detaching from the housing 10. The axial bearing member 40 ensures that the housing 10 and / or the anti-detachment member 12 and the rotating member 30 are in rolling contact rather than sliding contact, which can effectively reduce the frictional resistance during adjustment, making the adjustment operation easier and smoother, thereby improving the user experience. Therefore, the cantilever device of this application can solve the problem of poor user experience caused by the large adjustment resistance of the cantilever device.

[0028] In some embodiments, the elastic member 20 is a spring.

[0029] It should be noted that the angle between the screwing component 30 and the elastic component 20 means that the elastic component 20 and the screwing component 30 are not coaxially connected and form a certain angle.

[0030] like Figure 5 and Figure 6 As shown, in the embodiments of this utility model, each axial bearing member 40 includes: a bearing seat 41, located on the outer periphery of the screwing member 30, the screwing member 30 being rotatably disposed relative to the bearing seat 41; a bearing member 42, connected to the outer periphery of the screwing member 30, the bearing seat 41 and the bearing member 42 being spaced apart along the rotation axis, the outer shell 10 or the anti-detachment member 12 pressing against the side of the bearing seat 41 away from the bearing member 42, the side of the bearing member 42 away from the bearing seat 41 abutting against the screwing member 30, the side of the bearing seat 41 facing the bearing member 42 being provided with a first annular groove 411, the side of the bearing member 42 facing the bearing seat 41 being provided with a second annular groove 421, the openings of the first annular groove 411 and the second annular groove 421 being opposite each other to form an annular raceway; and a plurality of rolling elements 43, spaced apart along the circumference of the screwing member 30, the rolling elements 43 being rotatably disposed within the annular raceway, the bearing seat 41 and the bearing member 42 being engaged by the rolling elements 43.

[0031] In the above technical solution, the engagement of the first annular groove 411 and the second annular groove 421 between the bearing seat 41 and the bearing member 42 forms an annular raceway, providing a track for the placement of multiple rolling elements 43. The multiple rolling elements 43 are distributed in the annular raceway along the circumference of the screwing member 30, which can not only withstand axial force, but also roll smoothly in the annular raceway, thereby realizing the rolling fit between the bearing seat 41 and the bearing member 42 instead of direct sliding friction, which can reduce the resistance in the transmission of axial force and improve the smoothness of adjustment.

[0032] Specifically, when the user rotates the rotating component 30, the rolling element 43 between the bearing seat 41 and the bearing member 42 begins to roll within the annular raceway. This rolling mechanism ensures low-friction characteristics during the rotating operation, allowing the user to make a wide range of adjustments with relatively small force. Simultaneously, the position of the second end of the elastic member 20 on the rotating component 30 changes accordingly, adjusting the degree of extension or contraction of the elastic member 20, thereby altering the magnitude of the supporting force and meeting the stability requirements of the display at different angles and positions.

[0033] In some embodiments, both the support base 41 and the support member 42 are annular gaskets.

[0034] Specifically, in the embodiments of this utility model, the axial bearing member 40 further includes a retainer installed between the bearing seat 41 and the bearing member 42. Along the circumference of the screwing member 30, the retainer is provided with a plurality of retaining holes at intervals, and a plurality of rolling elements 43 are respectively rotatably disposed in the plurality of retaining holes.

[0035] In the above technical solution, multiple retaining holes are arranged circumferentially along the screwing member 30. These retaining holes are spaced apart to provide independent rolling space for the rolling elements 43. Each rolling element 43 is placed in the corresponding retaining hole, which ensures their orderliness and stability during the rolling process and avoids direct contact between the rolling elements 43, thereby reducing friction and wear.

[0036] In some embodiments, a retainer may not be required.

[0037] like Figure 5 As shown in the embodiment of this utility model, the rolling element 43 is a ball. Since the ball is spherical, it can bear and transmit axial force in a very small contact area. At the same time, since its surface is smooth and it can roll in all directions around its own center line, when the screwing component 30 rotates, the ball can roll in the annular raceway with small frictional resistance, ensuring the smoothness and efficiency of the adjustment process.

[0038] In some embodiments, the rolling element 43 may also be a roller.

[0039] In some embodiments, the axial bearing member 40 is an end face bearing.

[0040] like Figure 2As shown in the embodiment of this utility model, the screwing component 30 includes a screwing body 31 and a limiting member 32 connected to the outer periphery of the screwing body 31. An axial bearing member 40 is provided between the anti-detachment component 12 and the limiting member 32. One end face of the axial bearing member 40 abuts against the anti-detachment component 12, and the other end face of the axial bearing member 40 abuts against the limiting member 32, so that the anti-detachment component 12 is pressed against the limiting member 32 by the axial bearing member 40 and rolls with the limiting member 32.

[0041] In the above technical solution, when the user rotates the main body 31, the limiting member 32 rotates relative to the anti-detachment member 12, and the balls or rolling elements in the axial bearing member 40 roll smoothly in the annular raceway. This can reduce the frictional resistance of the rotation operation, so that the force value of the elastic member 20 can be adjusted more easily.

[0042] like Figure 2 , Figure 4 and Figure 5 As shown in the embodiment of this utility model, the screwing component 30 further includes a support shaft 33 connected to the end of the screwing body 31 away from the anti-detachment component 12. The cross-sectional area of ​​the support shaft 33 is smaller than the cross-sectional area of ​​the screwing body 31. A first stepped surface 34 is provided between the support shaft 33 and the screwing body 31. The mounting hole 11 includes a first hole segment 111 and a second hole segment 112 communicating with the first hole segment 111. The cross-sectional area of ​​the first hole segment 111 is smaller than the cross-sectional area of ​​the second hole segment 112. A second stepped surface 113 is provided between the first hole segment 111 and the second hole segment 112. The support shaft 33 is rotatably engaged with the first hole segment 111. The screwing body 31 is rotatably disposed within the second hole segment 112. An axial bearing component 40 is provided between the first stepped surface 34 and the second stepped surface 113. One end face of the axial bearing component 40 abuts against the first stepped surface 34, and the other end face of the axial bearing component 40 abuts against the second stepped surface 113.

[0043] In the above technical solution, when performing the adjustment operation, the user rotates the screwing body 31, the support shaft 33 rotates within the first hole section 111, and the screwing body 31 rotates within the second hole section 112. The first step surface 34 and the second step surface 113 transmit axial force through the axial bearing member 40. One end face of the axial bearing member 40 abuts against the first step surface 34, and the other end face abuts against the second step surface 113. In this way, not only is the axial displacement of the screwing member 30 limited, ensuring its stability during the screwing process, but also the adjustment operation is made easier and smoother by reducing rolling friction during rotation. This ensures the stable rotation of the screwing member 30 within the housing and the effective adjustment of the force value.

[0044] like Figure 2 As shown, in some embodiments, the first step surface 34 and the second step surface 113 may also abut against each other.

[0045] like Figure 2 and Figure 5 As shown in the embodiment of this utility model, the anti-detachment component 12 is threadedly engaged with the mounting hole 11. Thus, when it is necessary to install or adjust the connection between the screwing component 30 and the housing 10, the user can rotate the anti-detachment component 12 to change the thread engagement depth with the mounting hole 11, thereby adjusting the clamping force of the anti-detachment component 12 on the screwing component 30. This allows the anti-detachment component 12 to precisely clamp the screwing body 31 according to the actual situation, ensuring its stability and smooth rotation within the housing. This guarantees the stability of the device during use and reduces the risk of operational difficulties or loose connections due to over- or under-clamping, improving the reliability of the entire cantilever adjustment structure and the user experience. Furthermore, the threaded connection facilitates the disassembly and maintenance of the device, reducing maintenance costs.

[0046] In some embodiments, the anti-detachment component 12 is a nut.

[0047] In some embodiments, the anti-detachment member 12 may also be riveted to the mounting hole 11.

[0048] like Figure 3 As shown in the embodiment of this utility model, the outer shell 10 includes a cantilever 16, a first connecting seat 13, a second connecting seat 14, and a connecting rod 15. The two ends of the connecting rod 15 are pivotally connected to the first connecting seat 13 and the second connecting seat 14, respectively. The two ends of the cantilever 16 are pivotally connected to the first connecting seat 13 and the second connecting seat 14, respectively, to form a quadrilateral structure. The screwing member 30 is rotatably connected to the first connecting seat 13. The first end of the elastic member 20 is connected to the second connecting seat 14, the cantilever 16, or the connecting rod 15. The first connecting seat 13 is provided with a mounting hole 11.

[0049] In the above technical solution, the two ends of the connecting rod 15 are pivotally connected to the first connecting seat 13 and the second connecting seat 14 respectively. At the same time, the two ends of the cantilever 16 are also pivotally connected to the first connecting seat 13 and the second connecting seat 14, forming a dynamic quadrilateral structure that can adapt to multiple angle changes. When adjusting the angle of the cantilever 16, the user can rotate the rotating component 30 to drive the elastic component 20 to undergo corresponding extension or contraction changes, thereby changing the balance force acting on the cantilever 16, so that the cantilever 16 can achieve self-stability at different angles according to the user's needs.

[0050] In some embodiments, the cantilever 16 and the connecting rod 15 are of equal length. The cantilever 16, the first connecting seat 13, the second connecting seat 14 and the connecting rod 15 each have two holes and are connected by fasteners to form a closed parallelogram structure. The second connecting seat 14 can move relative to the first connecting seat 13.

[0051] like Figure 2 and Figure 5 As shown in the embodiment of the present invention, the adjusting component further includes an adjusting member 50, the second end of the elastic member 20 is connected to the adjusting member 50, and the adjusting member 50 is located on the outer periphery of the screwing member 30 and is threadedly engaged with the screwing member 30.

[0052] In the above technical solution, when the user needs to adjust the balance force of the display, he / she can directly rotate the screwing component 30. By adjusting the threaded connection between the adjusting component 50 and the screwing component 30, the adjusting component 50 can move on the screwing component 30 to change the extension or contraction state of the elastic component 20, thereby controlling the support force it provides. The threaded connection of the adjusting component 50 not only provides a fixing point for the other end of the elastic component 20, but also serves as an adjustment mechanism, allowing the user to adjust the force value of the elastic component 20 by rotating the screwing component 30.

[0053] In some embodiments, the screwing member 30 is an adjusting screw, which is fixed to the first connecting seat 13 by riveting or anti-dislodgement member, so that the adjusting screw can rotate relative to the first connecting seat 13 without dislodging; the adjusting member 50 is a threaded slider, one end of which is connected to the adjusting screw by a thread, so that the threaded slider can move up and down, and the other end of the threaded slider is connected to an elastic member by a fastener. The other end of the elastic member can be fixed at a certain position on the second connecting seat 14, the cantilever 16, or the connecting rod 15. Due to the action of the elastic member, the second connecting seat 14 will be subjected to an upward force, which can be used to provide a display mounted on the head assembly, so that it can be suspended at any position during up and down movement.

[0054] An embodiment of this utility model provides a monitor stand, including a base, a mounting panel, and the aforementioned cantilever device, which connects the base and the mounting panel. The mounting panel is used to mount the monitor.

[0055] The aforementioned monitor bracket possesses all the advantages of the aforementioned cantilever device, which will not be elaborated upon here.

[0056] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: By rotating the rotating component, the user can cause the second end of the elastic component to change position on the rotating component, thereby changing the extension or contraction state of the elastic component, thus realizing the adjustment of the support force, ensuring that the display can be stably suspended in any position, providing the user with a comfortable and efficient user experience. During this movement, the anti-detachment component can press and limit the rotating component to prevent the rotating component from detaching from the shell, while the axial bearing component can make the shell and / or the anti-detachment component and the rotating component roll contact rather than slide contact, which can effectively reduce the frictional resistance during adjustment, making the adjustment operation more convenient and smooth, thereby improving the user's user experience.

[0057] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
