[0039] The present invention is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted under different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0040] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0041] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0042] This application provides a display stand, please refer to Figures 1-15The display stand includes a mounting member 100, a connecting arm 200, and a display support base 300 connected in sequence. The mounting member 100 is used to be fixed on the installation base, and the display support base 300 is used to install the display. The display stand also includes a locking assembly 400. The display support base 300 is adjustably connected to the end of the connecting arm 200 away from the mounting member 100 and can be rotated around a first rotation axis, thereby adjusting the relative position of the entire display support base 300 and the installation base. The locking assembly 400 is installed on one of the connecting arm 200 and the display support base 300, and the locking assembly 400 is used to cooperate with the other of the connecting arm 200 and the display support base 300 to at least lock the display support base 300 and prevent the display support base 300 from rotating downward relative to the connecting arm 200.

[0043] The present application sets a connecting arm 200 to connect the mounting member 100 and the display support base 300, so that the display support base 300 can move relative to the mounting member 100, which is convenient for adjusting the position of the display. At the same time, since the display bracket also has a locking component 400, the display support base 300 can effectively bear the weight of the display after the display is loaded. The locking component 400 can at least effectively prevent and avoid the display support base 300 being driven by the display to rotate downward relative to the connecting arm 200 during use, thereby effectively improving the stability of the display bracket.

[0044] It should be noted that the above-mentioned "locking assembly 400 is used to cooperate with the other of the connecting arm 200 and the display support base 300 to at least lock the display support base 300 and prevent the display support base 300 from rotating downward relative to the connecting arm 200". On the one hand, the present application does not limit the specific structure and specific scheme of the locking assembly 400. The locking assembly 400 can be any feasible scheme, and in the direction of rotation of the rotating connecting assembly 320 around the first rotation axis, the locking assembly 400 can only prevent the display support base 300 from rotating downward relative to the connecting arm 200, or it can be locked simultaneously in the two-way rotation direction, such as a latch-type locking scheme or other feasible schemes. On the other hand, regardless of whether it is a solution that only prevents the display support base 300 from rotating downward or a solution that locks both bidirectional rotations, the locking assembly 400 has a state of not cooperating with the other of the connecting arm 200 and the display support base 300 to unlock the connecting arm 200 and the display support base 300, so that both the connecting arm 200 and the display support base 300 can rotate around the first rotation axis within the designed rotation angle range to adjust the angle and relative position.

[0045] In some embodiments, when the locking assembly 400 locks the display support base 300 and the connecting arm 200, the display support base 300 can rotate upward relative to the connecting arm 200 under the action of external force from the user. After the display support base 300 rotates upward relative to the connecting arm 200 and adjusts to the desired posture and position, the locking assembly 400 can continue to connect and cooperate to continue to lock the display support base in this position, thereby achieving the function and effect of limiting the display support base 300 from rotating downward relative to the connecting arm 200, so as to bear the weight of the display and lock the spatial position of the display when in use.

[0046] In some embodiments, please refer to Figure 2-Figure 3 、 Figure 7-Figure 8 The locking assembly 400 includes a stopper 410, which is adjustably mounted on one of the connecting arm 200 and the display support base 200. The stopper 410 has a first state and a second state. In the first state, the stopper 410 is engaged with the other of the connecting arm 200 and the display support base 300 to at least lock the display support base 300 and prevent the display support base 300 from rotating downward relative to the connecting arm 200. In the second state, the stopper 410 is disengaged from the other of the connecting arm 200 and the display support base 300, so that both the display support base 300 and the connecting arm 200 can rotate bidirectionally around the first rotation axis within the designed angle range.

[0047] This application does not limit the specific adjustment method of the stopper 410. In some embodiments, the stopper 410 can be manually adjusted to manually switch between the first and second states. In some embodiments, the stopper 410 can be properly arranged to automatically reset the stopper 410 using gravity. Specifically, the stopper 410 can be manually switched from the first state to the second state, and then, under the action of gravity, the stopper 410 can automatically switch from the second state to the first state. In other embodiments, other feasible automatic reset methods besides automatic reset by gravity can also be used.

[0048] In some embodiments, please refer to Figure 4 and Figure 8-Figure 9 The stopper 410 includes a latching portion 411. One of the connecting arm 200 and the display support base 300 is equipped with the stopper 410, while the other has a gear portion 323 that mates with the latching portion 411. In a first state, the latching portion 411 is connected to the gear portion 323, allowing the display support base 300 to rotate upward about a first rotation axis. In a second state, the latching portion 411 is disengaged from the gear portion 323, allowing the display support base 300 to rotate bidirectionally about the first rotation axis. For example, in some embodiments, the connecting arm 200 and the display support base 300 can form a one-way rotation structure similar to a ratchet and pawl engagement through the gear portion 323 and the latching portion 411.

[0049] It should be noted that the gear portion 323 refers to a plurality of tooth structures that can cooperate with the locking portion 411 to realize the rotation function. In some embodiments, the gear portion 323 can be integrally formed with the corresponding structural member. In some embodiments, the gear portion 323 can also be an independent gear that is connected to other components of the rotating connection assembly 320 to realize the overall rotation of the display support about the first rotation axis.

[0050] In some embodiments, please refer to Figure 4 and Figure 8-Figure 9 The locking assembly 400 also includes a first elastic member 342, one end of the first elastic member 342 is connected to or abuts the stop member 410, and the other end of the first elastic member 342 is connected to or abuts the connecting arm 200 or the display support base 300 on which the stop member 410 is installed. The first elastic member 342 is used to drive the stop member 410 to reset from the second state to the first state, and then the installation arrangement scheme of the stop member 410 can be adaptively adjusted according to needs. Under the action of the first elastic member 342, it can be ensured that the stop member 410 can be automatically reset. The first elastic member 342 can also improve the transmission stability of the stop member 410 and the gear part 323 in the first state, so that the stop member 410 can effectively cooperate with the gear part 323 in transmission.

[0051] This application does not limit the coordination manner between the stop member 410, the connector 240, the connecting arm 200, the display support 300 and the gear portion 323. This application does not specifically limit the installation scheme and the adjustment scheme of the stop member 410, as long as the above-mentioned required functions can be achieved.

[0052] In some embodiments, please refer to Figures 1-6The stopper 410 is rotatably mounted on the connecting arm 200 or the display support base 300 in a direction parallel to the first rotation axis. The stopper 410 has a first movable end 412 and a second movable end 413. The stopper is provided at the first movable end 412, and the first elastic member 342 is connected to the second movable end 413. The stopper 410 is rotatably mounted, and the rotation axis of the stopper 410 is parallel to the first rotation axis. In the first state, the locking portion 411 is inserted into a tooth of the gear portion 323, locking the connecting arm 200 and the display support base 300 at a fixed angle to prevent the display support base 300 from rotating clockwise, i.e., rotating downward, relative to the connecting arm 200 about the first rotation axis under the weight of the display. When the display support base 300 is manually adjusted to rotate counterclockwise, i.e., upward, about the first rotation axis relative to the connecting arm 200, the first elastic member 342 causes the stopper 410 to rotate accordingly about its own rotation axis. The latching portion 411 always engages the tooth surface of the gear portion 323, allowing the latching portion 411 to sequentially insert into the next tooth, locking the gear portion 323 at different angles. Simultaneously, the second movable end 413 can be manually driven to rotate the first movable end 412 away from the gear portion 323. This switches the stopper 410 from the first state to the second state, completely disengaging the latching portion 411 from the gear portion 323. The display support base 300 can then freely rotate in both directions about the first rotation axis relative to the connecting arm 200 to adjust to any angle.

[0053] In some embodiments, please refer to Figures 1-6 The stop member 410 is connected to the connecting arm 200 by rotating in a direction parallel to the first rotation axis. The second movable end 413 includes a toggle portion 414 exposed on the side of the connecting arm 200. The toggle portion 414 extends out of the connecting arm 200, making it convenient for the user to directly push or press the toggle portion 414, thereby completely disengaging the stop member 410 from the gear portion 323, so that the display support base 300 can rotate freely around the first rotation axis relative to the connecting arm 200.

[0054] In some embodiments, please refer to Figure 2-Figure 5 In order to control the overall size and reduce the risk of possible collision and abrasion to the user, the outer side of the connecting arm 200 can also have a clearance portion 248 for the toggle portion 414 to rotate. The toggle portion 414 is at least partially embedded in the clearance portion 248, effectively avoiding the interference of the connecting arm 200 with the rotation of the stop member 410.

[0055] And / or, in some embodiments, in order to facilitate the user to apply force, the outer surface of the toggle portion 414 facing away from the connecting arm 200 is a rough surface to increase friction. Figure 3 and Figure 4 The second movable end 413 is L-shaped as a whole, and the toggle portion 414 is parallel to the outer surface of the corresponding portion of the connecting arm 200.

[0056] In other embodiments, please refer to Figure 7-Figure 9 The stopper 410 can also be adjustably slidably mounted on the connecting arm 200 or the display support base 300. Along the sliding direction of the stopper 410, one end of the first elastic member 342 is connected to the stopper 410, and the other end of the first elastic member 342 is connected to the connecting arm 200 or the display support base 300 on which the stopper 410 is mounted. The stopper 410 has a limiting portion 415 for cooperating with the connecting arm 200 or the display support base 300. The stopper 410 is positioned and mounted by the limiting portion 415 and the first elastic member 342. In this case, the first elastic member 342 simultaneously serves to install the limit stopper 410 and reset the stopper 410.

[0057] Please refer to Figure 9 The stopper 410 has an air-avoiding groove, and the locking portion 411 is a protruding structure formed by the groove wall of the air-avoiding groove. The locking portion 411 can be locked into any tooth of the gear portion 323. When the gear portion 323 rotates downward, the gear portion 323 pushes the stopper 410 to slide and further compresses the first elastic member 342. Under the action of the first elastic member 342, the locking portion 411 always fits the tooth surface of the gear portion 323. After rotating by an angle corresponding to the tooth pitch, the stopper 410 returns to its original position under the action of the first elastic member 342 and is inserted into the next tooth, thereby locking and limiting the downward rotation of the display support 300 relative to the connecting arm 200.

[0058] In some embodiments, please refer to Figure 7-Figure 9 The stopper 410 is slidably mounted on the connecting arm 200 in a direction perpendicular to the first rotation axis. To facilitate the installation of the stopper 410 and the first elastic member 342, the locking assembly 400 further includes a connecting pin 343. The stopper 410 is provided with a pin hole 416. The connecting arm 200 has a recessed groove 249, the opening of which faces the gear portion 323. The first elastic member 342 is mounted in the recessed groove 249. The connecting pin 343 is mounted in the pin hole 416 and extends into the recessed groove 249. The first elastic member 342 is in a compressed state and acts on the connecting pin 343. In the second state, the stopper 410 slides to further compress the first elastic member 342, thereby simplifying the assembly steps of the display support 300 and reducing the assembly difficulty.

[0059] In some embodiments, please refer to Figure 9The limiting portion 415 is a step structure for abutting the outer side surface of the connecting arm 200. One end of the stop member 410 has a gripping portion 417 exposed on the connecting arm 200. Along the sliding direction of the stop member 410, the gripping portion 417 is located on the side of the step structure away from the pin hole 416, so that the stop member 410 can be pulled outward by the gripping portion 417, so that the locking portion 411 is completely disengaged from the gear portion 323, and the gear portion 323 can rotate freely in the air avoidance groove. After adjusting to the desired angle, the external force is removed. Under the action of the first elastic member 342, the stop member 410 can be reset and lock the gear portion 323 again, so that the gear portion 323 can only rotate upward relative to the connector 240.

[0060] Please refer to Figures 1-17 The connecting arm 200 is connected to the mounting member 100. The connecting arm 200 includes a connecting head 240 and at least one main arm 210 that are rotatably connected in sequence. The display support base 300 is adjustably rotatably connected to the connecting head 240 around a first rotation axis. The locking assembly 400 is installed on one of the connecting head 240 and the display support base 300, and the locking assembly 400 is used to cooperate with the other of the connecting head 240 and the display support base 300 to at least lock the display support base 300 and prevent the display support base 300 from rotating downward relative to the connecting head 240.

[0061] When the connecting arm 200 includes at least two main arms 210, each main arm 210 is movably connected in sequence. Increasing the number of main arms 210 increases the range of motion and degree of freedom of the display support 300, further enhancing the adjustability of the display stand. For example, the connecting arm 200 includes two main arms 210, which are rotatably connected to each other. The mounting member 100 and the display support 300 are respectively disposed at ends of the two main arms 210 that are spaced apart from each other.

[0062] In other examples, the number of the main arms 210 can also be set to one, three, or four as needed, and the rotation axes between the main arms 210 can be parallel, vertical, or staggered, which can be flexibly selected according to actual needs.

[0063] In one embodiment, please refer to Figure 4 One of the two rotatably connected main arms 210 is provided with a rotating connecting shaft 230, and the other is provided with a rotating shaft hole 214. The rotating connecting shaft 230 is passed through the rotating shaft hole 214 to enable the two main arms 210 to be rotatably connected; a fifth shaft sleeve 231 is sleeved on the rotating connecting shaft 230, and at least a portion of the fifth shaft sleeve 231 is clamped between the two main arms 210 to play a damping role, so that the rotation between the two main arms 210 has a damping effect.

[0064] In one embodiment, please refer to Figure 4The connector 240 is rotatably connected to the other end of one of the main arms 210, wherein the connector 240 has an axial hole 241. The connecting arm 200 also includes an adjustment shaft 220, one end of which is provided with a positioning protrusion 243. The other end of the adjustment shaft 220 passes through the axial hole 241 and is threadedly connected to the main arm 210. A third shaft sleeve 242 is sleeved on the adjustment shaft 220. The third shaft sleeve 242 includes a sleeve portion 2421 located within the axial hole 241 and a damping portion 2422 located outside the axial hole 241. The damping portion 2422 is clamped between the main arm 210 and the connector 240. In some embodiments, the axis of the axial hole 241 is perpendicular or substantially perpendicular to both the first rotation axis and the second rotation axis, which helps to further enhance the adjustability of the monitor stand. The positioning protrusion 243 cooperates with the third sleeve 242 to provide a damping effect for the relative rotation between the connecting head 240 and the connecting arm 200, thereby helping the connecting head 240 to be fixed at a desired angle relative to the connecting arm 200.

[0065] In a further embodiment, please refer to Figure 4 The adjusting shaft 220 is sleeved with a bearing 244 and a fourth sleeve 247. The bearing 244 and the fourth sleeve 247 are sandwiched between the positioning protrusion 243 and the connector 240, with the fourth sleeve 247 located on the side of the bearing 244 away from the positioning protrusion 243. The bearing 244 can assist in fixing the adjusting shaft 220, and the provision of the fourth sleeve 247 can enhance the rotation feel. In addition, the cooperation between the bearing 244 and the fourth sleeve 247 helps prevent the adjusting shaft 220 from loosening during use.

[0066] For example, please refer to Figure 1-Figure 5 The main arm 210 is bifurcated to form two support arms 211, and the two arms 211 are arranged in parallel. One side of the connecting head 240 is clamped between the two arms 211. The through-axis hole 241 is provided on the portion of the connecting head 240 clamped between the two arms 211. A threaded through hole 212 is provided on one support arm 211 corresponding to the through-axis hole 241, and an adjustment through hole 213 is provided on the other support arm 211 corresponding to the through-axis hole 241. The end opposite to the through-axis hole 241 and the threaded through hole 212 is coaxially expanded to form a step surface, and the two third sleeves 242 are both stepped. The third sleeve 242 is embedded in one end of the through-shaft hole 241 where a step surface is formed, and the damping portion 2422 of the third sleeve 242 is clamped between the step surface and the support arm 211, so that one side of the damping portion 2422 abuts against the main arm 210, and the other side abuts against the connecting head 240, so as to exert a damping effect when the connecting head 240 and the main arm 210 rotate relative to each other; the fourth sleeve 247 is clamped at one end of the through-shaft hole 241 away from the step surface, and the fourth sleeve 247 is partially clamped in the through-shaft hole 241 and partially extends into the adjustment through hole 213.

[0067] A bearing 244 is also provided in the adjustment hole 213. The bearing 244 can be a planar bearing 244. One side of the planar bearing 244 is positioned against the fourth sleeve 247, while the other side is abutted by the positioning projection 243. The end of the adjustment shaft 220 facing away from the positioning projection 243 is threaded for engagement with the threaded through hole 212. During installation, the end of the adjustment shaft 220 facing away from the positioning projection 243 is sequentially passed through the bearing 244, the fourth sleeve 247, the through-shaft hole 241, and the third sleeve 242, and screwed into the threaded through hole 212 until the positioning projection 243 and the bearing 244 are in contact with each other to the desired degree. By adjusting the degree of contact between the positioning projection 243 and the bearing 244, the degree of rotational damping between the connector 240 and the main arm 210 can be adjusted. To facilitate adjustment of the tightness of the adjustment shaft 220, a hexagonal slot can also be provided on the positioning projection 243 to facilitate tightening with a hexagonal wrench.

[0068] In other embodiments, the connector 240 may be provided only on one side of the main arm 210 , and other structures may be used to realize rotational connection between the connector 240 and the main arm 210 and between the main arms 210 .

[0069] In addition, in a specific embodiment, please refer to Figure 4 and Figure 5 The rotational connection structure between each main body arm 210 can be the same as the rotational connection structure between the main body arm 210 and the connector 240 described above, so that the rotational damping degree of each rotational connection can be adjusted in the same manner during use. Of course, other rotational connection structures can also be used between each main body arm 210.

[0070] In some embodiments, please refer to the figure, the display support base 300 includes a rotating connection component 320 and a mounting base 310. The rotating connection component 320 is adjustably connected to the connecting head 240 by rotation around a first rotation axis, thereby adjusting the height position and pitch angle of the rotating mounting base 310. The mounting base 310 is adjustably mounted on the rotating connection component 320 by rotation around a second rotation axis. The mounting base 310 is used to mount the display, so that the rotating connection component 320 can rotate relative to the connecting head 240 around the first rotation axis, and the mounting base 310 can rotate relative to the rotating connection component 320 around the second rotation axis, thereby further adjusting the orientation and angle of the mounting base 310 through multi-stage rotation, so that the display mounted on the mounting base 310 can adjust the angle and orientation, which helps to improve the adjustability of the display stand for easier use.

[0071] The rotational connection between the connector 240 and the rotational connection assembly 320 can be realized by means of a damping combination, thereby achieving rotational adjustment and locking after adjustment. Similarly, the rotational adjustment connection between the rotational connection assembly 320 and the mounting base 310 can also be realized by means of a damping combination. There are also a variety of damping solutions available, which are not limited in this application, and any feasible implementation scheme can be adopted. The display support base 300 provided in this application effectively limits the downward rotation of the display support base 300 relative to the connecting arm 200 through the locking assembly 400. While achieving the installation and fixing of the display, it can effectively bear the weight of the display, so that the display can be stably arranged at the desired position and height with a suitable posture, and there will be no change in the height position of the display due to instantaneous damping failure caused by long-term load-bearing or excessive weight of the display.

[0072] In some embodiments, the first rotation axis and the second rotation axis may intersect and form a certain angle. In some embodiments, the first rotation axis and the second rotation axis may be completely staggered and form a certain angle. For example, in some embodiments, the first rotation axis and the second rotation axis are arranged perpendicularly or approximately perpendicularly. The provision of the rotation connection assembly 320 enables the mounting base 310 to rotate relative to the connector 240 about the first rotation axis and the second rotation axis, thereby increasing the degrees of freedom of the mounting base 310 and further enhancing the adjustability of the display stand.

[0073] In one embodiment, please refer to Figure 4-Figure 6 The rotating connection assembly 320 includes a connection body 321 , the connection body 321 is rotationally connected to the connection head 240 , and the gear portion 323 is provided on the connection body 321 .

By controlling the displacement of the adjustment column 246, the degree of expansion and contraction of the expansion end 2451 of the expansion sleeve 245 can be adjusted, thereby varying the degree of contact between the expansion end 2451 of the expansion sleeve 245 and the second sleeve 3212, thereby adjusting the degree of rotational damping between the connector 240 and the connection body 321. In some embodiments, the second sleeve 3212 can be made of a wear-resistant material, such as engineering plastic, to improve wear resistance.

[0074] In some embodiments, a conical surface 2461 may be further provided at one end of the adjusting column 246 close to the expansion end 2451 of the expansion sleeve 245 . The conical surface 2461 is provided corresponding to the inclined surface 2454 , so that the adjusting column 246 can push the inclined surface 2454 to open the expansion end 2451 .

[0075] For example, please refer to Figure 2-Figure 6 The connector 240 is configured as a Y-shaped structure with two forks on one side. The end of the connecting body 321 that is rotatably connected to the connector 240 is inserted between the two forks of the connector 240. Two expansion sleeves 245 are provided. The expansion ends 2451 of the two expansion sleeves 245 each penetrate the portion of the connector 240 on one side of the connecting body 321 and extend into the second shaft sleeve 3212.

The annular boss 2453 is fixed to the connector 240 via fasteners to fix the expansion sleeve 245 on the connector 240. The adjustment column 246 has one end with a tapered surface 2461 that is threaded into the expansion sleeve 245 and close to the expansion end 2451 so that the tapered surface 2461 corresponds to the inclined surface 2454. The degree of expansion of the expansion end 2451 can be adjusted by screwing the adjustment column 246. In some embodiments, the adjustment column 246 can be made of a machine screw, and a hexagonal slot can be provided on one side of the adjustment column 246 close to the fixed end 2452 of the expansion sleeve 245 so that the adjustment column 246 can be adjusted using a hexagonal wrench.

[0076] In other embodiments, the connector 240 may also adopt other shapes and structures, and other rotational connection structures may also be adopted between the connection body 321 and the connector 240 , as long as the rotational connection between the rotational connection component 320 and the connector 240 is achieved.

[0077] In one embodiment, please refer to Figure 2-Figure 6 The rotating connection assembly 320 further includes a rotating fitting 322 , which is connected to the connection body 321 and movably engaged with the mounting seat 310 , so that the connection body 321 can rotate relative to the mounting seat 310 around the second rotation axis.

One end of a rotational engagement member 322 is connected to the sleeve portion 3213, and the other end of the rotational engagement member 322 is movably inserted into the retaining hole along a second rotation axis to enable movably engaging the rotational engagement member 322 with the mounting base 310. With the rotational engagement member 322 in contact, the mounting base 310 can rotate relative to the connecting body 321.

[0079] In some embodiments, the limiting hole is a stepped hole 3121, into which the sleeve portion 3213 is inserted. The so-called stepped hole 3121 refers to a reduced diameter hole with a stepped wall and a stepped surface. The stepped surface of the stepped hole 3121 faces away from the connecting body 321. One end of the rotating fitting 322 inserted into the stepped hole 3121 has a contact limiting surface 3221, which is used to abut against the stepped surface of the stepped hole 3121. In other embodiments, the limiting hole can also be a tapered hole or other hole that can accommodate the movable insertion of the rotating fitting 322.

The other end of the rotating fitting 322 is inserted into the stepped hole 3121 along the second rotation axis. The end inserted into the stepped hole 3121 has a clamping portion. The clamping portion has a retaining surface 3221 for abutting against the stepped surface of the stepped hole 3121. The retaining surface 3221 abuts against the stepped surface of the stepped hole 3121, allowing the rotating fitting 322 to be rotatably disposed in the stepped hole 3121. In some embodiments, the clamping portion can be provided as an annular protrusion 3222.

[0081] In a further embodiment, in order to improve the rotation damping effect between the rotation connection component 320 and the mounting base 310, please refer to Figure 6 、 Figure 10 -and Figure 13 A first shaft sleeve 3214 for increasing rotational damping is sleeved on the sleeve portion 3213 , and a gasket 3122 for increasing rotational damping is provided between the step surface of the step hole 3121 and the abutting limit surface 3221 .

In other embodiments, it can also include a clamping member, such as an existing mobile phone clamp or tablet computer clamp. In other embodiments, it can also be configured as a magnetic mount, such as a magnetic mount that can absorb a mobile phone or tablet computer, so that the mobile phone or tablet computer can be used as a display. In short, any structural member that can be used to secure any type of display can be used as the base 311.

[0088] In one embodiment, in order to adapt to different types of displays, please refer to Figure 10 -and Figure 15 The base 311 and the adapter 312 are detachably connected via a quick-release structure.

For example, in some embodiments, the mounting base can be a support pole or column on the director's car, and the mounting member 100 can be a pipe clamp. For example, please refer to Figure 1 and Figure 2 The pipe clamp is integrally mounted at one end of the connecting arm 200 and includes a fixed portion 110, a movable portion 120, and a clamping wrench 130.

The movable portion 120 and the fixed portion 110 together form a clamping cavity 140. After the support rod or column is inserted into the clamping cavity 140, the movable portion 120 is tightened by adjusting the clamping wrench 130 so that the support rod or column is clamped in the clamping cavity 140, completing the clamping installation. In other embodiments, other structural forms of pipe clamps may be used, and the pipe clamp may also be a separate structure from the connecting arm 200, as long as it can be fixed to the connecting arm 200.

The C-shaped clamp is provided with a top screw on one side or both sides of the clamping opening. When in use, the clamping opening is clamped on the edge of the desktop or board, and the top screw is adjusted to clamp the desktop or board in the clamping opening.

[0098] In summary, the display stand disclosed in this application has at least the following beneficial effects:

[0099] In the display stand of the present application, the connection arm 200 and the display support base 300 are adjusted and locked by damping, and the connection head 240 and the rotating connection component 320, as well as the rotation connection component 320 and the mounting base 310, are also adjusted and initially locked by damping. By providing the connection arm 200 to connect the mounting member 100 and the display support base 300, the rotating connection component 320 can rotate relative to the connection head 240 about a first rotation axis, and the mounting base 310 can rotate relative to the rotating connection component 320 about a second rotation axis, thereby further adjusting the orientation and angle of the mounting base 310 through multi-stage rotation, so that the display support base 300 can move relative to the mounting member 100, which helps to adjust the position of the display support base 300 during use, thereby improving the adjustability of the display stand and facilitating its use.

[0100] At the same time, the locking component 400 can realize auxiliary locking of the relative position of the rotating connection component 320 and the connecting head 240, effectively preventing the mounting base 310 and the rotating connection component 320 as a whole from rotating downward relative to the connecting head 240 due to the weight of the display, thereby keeping the position of the display fixed and improving the stability of the display installation.

[0101] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
