Description

Technical Field

[0001] This utility model relates to the field of photographic equipment technology, specifically to a monitor stand. Background Technology

[0002] In the photography industry, monitors are frequently used to showcase camera shots. With the widespread use of monitors, the application of monitor stands has also become commonplace. Monitor stands can be mounted on bases such as cameras or workbenches, allowing users to install the monitor in their desired workspace. However, while existing monitor stands provide stable mounting, they are prone to instability due to the constant weight of the monitor, making them unsuitable for practical use and causing inconvenience to users. Utility Model Content

[0003] The main technical problem this invention addresses is how to provide a monitor stand to improve the current technical problem of unstable monitor mounting.

[0004] The technical solution of this utility model is a monitor stand, comprising:

[0005] The support arm has a connecting part at one end, which is used to connect and fix it to the installation foundation.

[0006] A monitor mounting bracket is rotatably connected to the end of a support arm away from the connecting part about a first rotation axis. The monitor mounting bracket is used to mount a monitor.

[0007] And a locking assembly, the locking assembly including a swing block connected or abutting each other and a first elastic element, the first elastic element being used to provide an elastic force to the swing block;

[0008] The monitor mount includes an inner ring and an outer ring, with the outer ring and locking assembly located on the outer periphery of the inner ring. The inner ring has a transmission surface, and the outer ring has a mounting groove with an opening facing the transmission surface. A swing block is disposed in the mounting groove, and a first elastic element is disposed in the outer ring. When the monitor mount is subjected to a downward force relative to the monitor arm, the two ends of the swing block abut against the bottom of the mounting groove and the transmission surface, respectively, to lock the inner and outer rings. When the monitor mount is subjected to an upward force relative to the monitor arm, the swing block releases the lock between the inner and outer rings.

[0009] In one optional embodiment, the mounting groove is a recessed groove provided on the side of the outer ring portion along the first rotation axis, and the swing block and the first elastic member can be placed into the mounting groove from the side of the outer ring portion; the outer ring portion is also provided with a fixing structure for limiting the swing block and the first elastic member.

[0010] In one alternative embodiment, the outer ring portion includes a base and a retainer, and the fixing structure includes the aforementioned retainer. A mounting groove is provided on the side of the base along a first rotation axis; the retainer has two opposing wings along the first rotation axis, and both the base and the swing block partially extend into the space between the two wings. The retainer clamps the base and the locking assembly via the two wings to prevent the locking assembly from disengaging from the base. One of the retainer and the base is rotatably engaged with the inner ring portion.

[0011] In one alternative embodiment, a retainer is mounted between the inner ring and the base along the radial direction of the inner ring, one end of the swing block extends out of the mounting groove, and the retainer has an exposed portion for exposing the swing block. Both the retainer and the swing block are rotatably engaged with the inner ring.

[0012] In one alternative embodiment, the retainer is rotatably adjustable relative to the base and the inner ring, and the retainer has a manual operating part exposed to the support arm and / or the display mount, the manual operating part being used to manually drive the retainer to rotate about a first rotation axis so that the retainer can switch between a first position and a second position.

[0013] When the retainer is in the first position, the monitor mount can rotate upward relative to the support arm, and when the monitor mount is subjected to a downward force, the oscillating block locks the inner and outer rings.

[0014] When the retainer moves from the first position to the second position, the retainer can drive all the swing blocks to swing until each swing block is not pressed against the transmission surface, so as to unlock the inner ring and the outer ring, so that the display mounting base can rotate downward and upward relative to the bracket arm about the first rotation axis.

[0015] In one optional embodiment, the monitor bracket further includes a switching element movably disposed on the outer ring portion. The switching element can switch between a first position and a second position. When the switching element moves from the first position to the second position, the switching element can drive all the swing blocks to swing until each swing block is not in contact with the transmission surface, thereby unlocking the inner ring portion and the outer ring portion, so that the monitor mounting base can rotate downward and upward relative to the bracket arm about the first rotation axis.

[0016] In one optional embodiment, the switching member has an outer connecting portion, and an arc-shaped waist-shaped groove is provided on the outer ring portion. The outer connecting portion passes through the waist-shaped groove. The locking component also includes a second elastic member. One end of the second elastic member is connected to or abuts against the outer ring portion, and the other end of the second elastic member is connected to or abuts against the outer connecting portion. The second elastic member is used to reset the switching member from the second position to the first position without the action of external force.

[0017] In one optional embodiment, the mounting groove is provided with a positioning cam shaft co-oriented with the first rotation axis, and the swing block is provided with a mounting hole for the positioning cam shaft to pass through. The swing block is positioned in the mounting groove by the positioning cam shaft.

[0018] In one alternative embodiment, the mounting hole is a waist-shaped hole extending radially along the inner ring to allow the swing block a certain amount of movement.

[0019] In one alternative embodiment, the locking assembly includes multiple sets of swing blocks and a first elastic element equal in number to the number of swing blocks, the multiple sets of swing blocks being spaced apart circumferentially along the outer ring portion;

[0020] A set of swing blocks may include one or two swing blocks; when a set of swing blocks includes two swing blocks, the two swing blocks are arranged opposite each other along the direction of the first rotation axis.

[0021] According to the monitor bracket of the above embodiment, the monitor mounting base can rotate relative to the bracket arm, allowing the monitor mounting base to move relative to the mounting base, which facilitates the adjustment of the position of the monitor mounting base during use. The locking component, the outer ring, and the inner ring cooperate, and the locking component can simultaneously abut against the inner ring and the outer ring, thereby locking the inner ring and the outer ring and effectively preventing and avoiding the monitor mounting base from rotating downward relative to the bracket arm due to the weight of the monitor. In addition, both the swing block and the first elastic element are located on the outer ring. Since the switching between locking and unlocking between the inner and outer rings is achieved by driving the swing block to swing in the opposite direction through the transmission surface of the inner ring, the swing block is also installed in a movable manner when it is installed on the outer ring. That is, the mounting groove on the outer ring provides installation space for the swing block. After the swing block is installed in the mounting groove, there is still a certain amount of room for movement. Therefore, the installation posture of the swing block is not unique. As long as the swing block and the first elastic element are installed in place and cooperate with each other, and then the monitor mounting base and bracket arm are assembled, the locking component can be stably arranged between the inner and outer rings. The swing block can lock or unlock the inner and outer rings. The assembly scheme between the locking component, the inner ring and the outer ring is simple, which facilitates the assembly of the monitor bracket and can effectively improve the production efficiency of the finished monitor bracket.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0037] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0038] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0039] The applicant has discovered that some monitor stands in the current related technology lack a locking function, resulting in unstable monitor fixation. While some monitor stands do have a locking function, their relatively complex structure leads to cumbersome assembly steps, high assembly difficulty, and hinders product manufacturing efficiency. To address these issues, this application provides a monitor stand that, on the one hand, adds a locking component to improve the unstable monitor fixation problem of current monitor stands. On the other hand, based on the existing locking function, by designing and coordinating the various structural parts of the monitor stand, the assembly scheme can be simplified, effectively reducing the difficulty of assembly and facilitating the assembly and installation of the locking component.

[0040] In some embodiments, please refer to Figures 1-8The monitor bracket disclosed in this application includes a bracket arm 100, a monitor mounting base 200, and a locking assembly 300. One end of the bracket arm 100 is provided with a connecting part for connecting and fixing to a mounting base. The monitor mounting base 200 is rotatably connected to the end of the bracket arm 100 away from the connecting part about a first rotation axis and is used to mount a monitor. The monitor mounting base 200 can rotate relative to the bracket arm 100, so that the monitor mounting base 200 can move relative to the mounting base, which helps to adjust the position of the monitor mounting base 200 during use.

[0041] Please refer to Figures 1-7 The locking assembly 300 includes a swing block 310 connected to or abutting against it and a first elastic member 320, which provides an elastic force to the swing block 310. One of the support arm 100 and the display mounting base 200 includes an inner ring portion 210, and the other includes an outer ring portion 110. Both the outer ring portion 110 and the locking assembly 300 are located on the outer periphery of the inner ring portion 210. At least the swing block 310 and the outer ring portion 110 are rotatably engaged with the inner ring portion 210 about a first rotation axis. The inner ring portion 210 has a transmission surface 211, and the outer ring portion 110 has a mounting groove 113 opening towards the transmission surface 211. The swing block 310 is disposed within the mounting groove 113, and the first elastic member 320 is disposed within the outer ring portion 110. When the monitor mounting base 200 is subjected to a downward force relative to the support arm 100, the two ends of the swing block 310 abut against the bottom of the mounting groove 113 and the transmission surface 211, respectively, to lock the inner ring portion 210 and the outer ring portion 110. When the monitor mounting base 200 is subjected to an upward force relative to the support arm 100, the swing block 310 releases the lock between the inner ring portion 210 and the outer ring portion 110. In other words, the locking component 300, the outer ring portion 110, and the inner ring portion 210 cooperate, and the locking component 300 can simultaneously abut against the inner ring portion 210 and the outer ring portion 110, thereby locking the inner ring portion 210 and the outer ring portion 110, effectively preventing and avoiding the monitor mounting base 200 from rotating downward relative to the support arm 100 due to the weight of the monitor, thus keeping the position of the monitor fixed and effectively improving the stability of the monitor installation.

[0042] According to the aforementioned monitor bracket, the swing block 310 and the first elastic element 320 are both located on the outer ring portion 110. The switching between locking and unlocking between the inner ring portion 210 and the outer ring portion 110 is achieved through the swing block 310. In the initial state, the swing block 310 is in the corresponding position under the action of the first elastic element 320, and both ends of the swing block 310 are in contact with the groove wall and the transmission surface 211 of the mounting groove 113. When the monitor mounting base 200 is subjected to a downward force relative to the bracket arm 100, since the radial projection size of the swing block 310 on the inner ring portion 210 is slightly larger than the size between the inner ring portion 210 and the outer ring portion 110, the two ends of the swing block 310 will press against the groove wall and the transmission surface 211 of the mounting groove 113, making the swing block 310 unable to move, and the swing block 310, the inner ring portion 210 and the outer ring portion 110 are relatively locked. When the monitor mounting base 200 is subjected to an upward force relative to the support arm 100, the swing block 310 can swing slightly after being subjected to the force to change its posture. However, the swing and posture change of the swing block 310 can be invisible to the naked eye. Ultimately, the projected size of the swing block 310 in the radial direction of the inner ring portion 210 is equal to or slightly smaller than the size between the inner ring portion 210 and the outer ring portion 110, thereby unlocking the inner ring portion 210 and the outer ring portion 110. In addition, when the swing block 310 is installed on the outer ring 110, it is also installed in a movable manner. That is, the mounting groove 113 on the outer ring 110 provides installation space for the swing block 310. After the swing block 310 is installed in the mounting groove 113, there is still a certain amount of room for movement. The installation posture of the swing block 310 is not unique. The assembly of the swing block 310 is allowed to have a reasonable range of deviation. As long as the swing block 310 and the first elastic member 320 are installed in place and cooperate with each other, and then the monitor mounting base 200 and the bracket arm 100 are assembled, the locking component 300 can be stably arranged between the inner ring 210 and the outer ring 110. The swing block 310 can lock or unlock the inner ring 210 and the outer ring 110. The assembly scheme between the locking component 300, the inner ring 210 and the outer ring 110 is simple, which facilitates the assembly of the monitor bracket and can effectively improve the production efficiency of the finished monitor bracket.

[0043] Those skilled in the art, upon understanding the inventive concept of this application, should be aware of the specific structural design for locking and unlocking the swing block 310. In some embodiments, the end face of the swing block 310 that contacts the transmission surface 211 of the inner ring portion 210 can be a bevel, so that the swing block 310 does not press against the transmission surface of the inner ring portion after slight swinging. When the inner ring portion 210 rotates in different directions relative to the outer ring portion, two different types of engagement are generated between it and the swing block 310: a resisting engagement and a rotational engagement. In some embodiments, the end face of the swing block 310 that contacts the transmission surface 211 of the inner ring portion 210 can also be designed as a curved surface. Please refer to [reference needed]. Figures 4-6The end face of the swing block 310 includes two connected arc surfaces with different curvatures, which allows the swing block 310 and the inner ring 210 to produce two different kinds of fits.

[0044] In some embodiments, to facilitate the installation of the locking component 300 and further simplify the assembly scheme between the locking component 300 and the outer ring portion 110, please refer to... Figure 2 , Figures 4-7 The mounting groove 113 is a recessed groove located on the side of the outer ring portion 110 along the first rotation axis. The swing block 310 and the first elastic member 320 can be inserted into the mounting groove 113 from the side of the outer ring portion 110. Since the side of the swing block 310 is exposed, the connection between the first elastic member 320 and the swing block 310 can be facilitated. In order to prevent the locking component 300 from disengaging from the outer ring portion 110 during use, the outer ring portion 110 is also provided with a fixing structure for limiting the swing block 310 and the first elastic member 320, so as to prevent the swing block 310 and the first elastic member 320 from falling off from the side of the outer ring portion 110, so that the position of the locking component 300 on the outer ring portion 110 remains approximately fixed, and thus the fixing structure ensures the stable cooperation of the locking component 300, the inner ring portion 210 and the outer ring portion 110.

[0045] This application does not limit the selection and arrangement of the fixing structure. Those skilled in the art can choose any feasible implementation scheme. For example, a rotatable, slidable or detachable baffle can be added to the side of the base 111 to close the side opening of the mounting groove 113 after the locking component 300 is inserted. Alternatively, the base 111 and the swing block 310 can be positioned by a structure such as a pin.

[0046] In some embodiments, please refer to Figure 2 , Figures 4-7 The outer ring portion 110 includes a base 111 and a retainer 112. The retainer 112 constitutes the aforementioned fixing structure. A mounting groove 113 is provided on the side of the base 111 along the first rotation axis. The swing block 310 and the first elastic member 320 are both provided on the base 111, and the swing block 310 and the first elastic member 320 protrude from the side of the base 111. The retainer 112 is connected to the base 111 and has a wing 1121. The locking assembly 300 is limited in the mounting groove 113 along the first rotation axis by the wing 1121 to prevent the locking assembly 300 from disengaging from the side of the mounting groove 113 from the base 111. The retainer 112 constitutes the aforementioned fixing structure. To further improve the stability of the display bracket, in addition to the swing block 310 rotating with the inner ring portion 210, one of the retainer 112 and the base 111 also rotating with the inner ring portion 210.

[0047] In some embodiments, please refer to Figures 5-7The retainer 112 has two opposing wings 1121 along a first rotation axis. The base 111 and the swing block 310 both partially extend into the space between the two wings 1121. The retainer 112 clamps the base 111 and the locking assembly 300 through the two wings 1121. The phrase "the retainer 112 clamps the base 111 and the locking assembly 300 through the two wings 1121" can include various feasible specific solutions. For example, in some embodiments, only the first side of the base 111 may have a mounting groove 113. After the retainer 112 is positioned and connected to the base 111, the swing block 130 is positioned between one of the wings 1121 and the groove wall of the mounting groove 113 along the spacing direction of the two wings 1121, and the other wing 1121 cooperates with the second side of the base. In other embodiments, the mounting groove 113 may extend through the base 111 along the first rotation axis. Along the direction of the first rotation axis, the two ends of the swing block 130 and the two sides of the base 113 are respectively positioned and engaged with the two wings 1121. The base 111 and the locking assembly 200 are both positioned between the two wings 1121. In still other embodiments, please refer to... Figure 6 Along the first rotation axis, the base 111 has mounting grooves 113 and corresponding swing blocks 130 and first elastic elements 320 on both sides. Along the interval direction of the two wings 1121, each swing block is positioned between the wing 1121 on the same side and the groove wall of the mounting groove 113. The two sides of the base 113 are also positioned and engaged with the two wings 1121 respectively.

[0048] In some embodiments, please refer to Figures 2-7 Along the radial direction of the inner ring portion 210, the retainer 112 is disposed between the inner ring portion 210 and the base 111. One end of the swing block 310 extends out of the mounting groove 113. The retainer 112 has an exposed portion for exposing the swing block 310. Both the retainer 112 and the swing block 310 are rotatably engaged with the inner ring portion 210. The retainer 112 has the function of preventing the locking component 300 from disengaging from the base 111 and improving the stability of the monitor bracket during use.

[0049] In some embodiments, please refer to Figures 4-7The retainer 112 is rotatable and adjustable relative to the base 111 and the inner ring 210. The retainer 112 has a manual operating part 1122 exposed to the support arm 100 and / or the display mounting base 200. The manual operating part 1122 is used to manually drive the retainer 112 to rotate around a first rotation axis so that the retainer 112 can switch between a first position and a second position. When the retainer 112 is in the first position, the display mounting base 200 can rotate upward relative to the support arm 100, and when the display mounting base 200 is subjected to a downward force, the swing block 310 locks the inner ring 210 and the outer ring 110. When the retainer 112 moves from the first position to the second position, the retainer 112 can drive all the swing blocks 310 to swing until each swing block 310 is not pressed against the transmission surface 211, so as to unlock the inner ring 210 and the outer ring 110, so that the display mounting base 200 can rotate downward and upward relative to the support arm 100 around the first rotation axis. The display bracket in this embodiment makes full use of the structural features of the retainer 112. During the process of the retainer 112 moving back and forth between the first position and the second position, the two wings 1121 of the retainer 112 still clamp the base 111 and the locking component 300, effectively preventing the locking component 300 from disengaging from the base 111.

[0050] This application does not limit the specific structure of the hand control unit 1122. Those skilled in the art can make adaptive adjustments according to actual needs. For example, the user can operate the hand control unit 1122 by pushing, pressing or flicking.

[0051] In some embodiments, please refer to Figures 4-7 The base 111 and the two wings 1121 of the cage 112 slide together to guide the position of the cage 112, so that the cage 112 can rotate about the first rotation axis relative to the base 111 and the inner ring 210.

[0052] In some embodiments, please refer to Figures 1-7 The monitor bracket also includes a switching element movably located on the outer ring portion 110. The switching element can switch between a first position and a second position. When the switching element moves from the first position to the second position, it drives all the swing blocks 310 to swing until none of the swing blocks 310 are pressed against the transmission surface 211, thereby unlocking the inner ring portion 210 and the outer ring portion 110, allowing the monitor mounting base 200 to rotate downward and upward relative to the bracket arm 100 around the first rotation axis. When the switching element is in the first position, the swing blocks 310 can unidirectionally lock the inner ring portion 210 and the outer ring portion 110, so that the monitor mounting base 200 can only rotate upward relative to the bracket arm 100 around the first rotation axis.

[0053] It should be noted that the retainer 112 in the above embodiment is a feasible solution for the switching component. Other implementation schemes can also be adopted for the switching component, and this application does not make specific limitations. For ease of understanding, in the monitor bracket disclosed in this application, when the switching component is in the first position, the working principle of the rotational engagement mechanism formed between the locking component 300, the bracket arm 100, and the monitor mounting base 200 is similar to the working principle of a one-way bearing. At this time, the monitor mounting base 200 can be rotated upward relative to the bracket arm 100 to raise the height position of the monitor mounting base 200. After the monitor mounting base 200 is adjusted upward into place and the external force is removed, the swing block 310 locks the inner ring 210 and the outer ring 110, so that the monitor mounting base 200 cannot rotate downward relative to the bracket arm 100. When the switching element is adjusted to the second position, the engagement between the locking component 300, the support arm 100, and the monitor mounting base 200 is released. The swing block 310 can no longer abut against the transmission surface 211 of the inner ring 210, so that the swing block 310 does not obstruct the relative movement of the support arm 100 and the monitor mounting base 200. At this time, the monitor mounting base 200 can rotate freely relative to the support arm 100 around the first rotation axis, realizing clockwise and counterclockwise angle adjustment, that is, it can rotate upward and downward. At this time, the monitor mounting base 200 can rotate upward and downward arbitrarily relative to the support arm 100 within the adjustable angle range, improving the convenience of the monitor stand and making it easy for users to quickly adjust the monitor mounting base 200 to the required angle and position. In some embodiments, the monitor mounting base 200 can even be designed as a detachable split structure, thereby realizing angle adjustment within a 360° angle range.

[0054] In some embodiments, to enable the switching element to smoothly switch between the first and second positions and to return to the first position with relatively high precision, please refer to... Figures 5-8 The switching component has an outer connecting portion. The outer ring portion 110 is provided with an arc-shaped waist-shaped slot 122. The arc-shaped waist-shaped hole corresponds to the movement trajectory of the switching component and the outer connecting portion. The outer connecting portion passes through the waist-shaped slot 122. The locking component 300 also includes a second elastic member 330. One end of the second elastic member 330 is connected to or abuts against the outer ring portion 110, and the other end of the second elastic member 330 is connected to or abuts against the outer connecting portion. The second elastic member 330 is used to reset the switching component from the second position to the first position without the action of external force.

[0055] In some embodiments, please refer to Figures 1-8The inner ring portion 210 is disposed on the display mounting base 200. The support arm 100 includes a connector 120, a base 111, and a retainer 112. The connector 120 and the inner ring portion 210 are rotatably connected about a first rotation axis via a rotating shaft assembly. The base 111 and the retainer 112 constitute the outer ring portion 110. The base 111 is detachably positioned and assembled on the connector 120 to pre-assemble the locking component 300 and the outer ring portion 110. Then, the assembled locking component 300 and the outer ring portion 110 are integrally installed on the connector 120. After assembling the connector 120 and the inner ring portion 210, the locking component 300 and the outer ring portion 110 can be stably positioned between the connector 120 and the inner ring portion 210, and the swing block 310 can be driven and engaged with the transmission surface 211 of the inner ring portion 210.

[0056] In some embodiments, please refer to Figure 5 and Figure 8 The second elastic element 330 is a spring, and the outer connecting part is a locking post 340 that is threadedly connected to the retainer 112. The side of the connector 120 is provided with a spring arrangement groove 121 extending in an arc shape and a waist-shaped locking groove 122 that penetrates the side. The waist-shaped locking groove 122 communicates with the spring arrangement groove 121. The second elastic element 330 is installed in the spring arrangement groove 121. The locking post 340 is embedded in the side of the retainer 112 facing the spring arrangement groove 121. The locking post 340 passes through the waist-shaped locking groove 122, extends into the spring arrangement groove 121, and abuts against one end of the second elastic element 330.

[0057] In some embodiments, please refer to Figures 2-8 The retainer 112 has a positioning groove 1123 on its side and a spring ball 350 on the connector 120. When the retainer 112 is in the first position, the retractable end of the spring ball 350 is aligned with the positioning groove 1123 on the retainer 112 and the spring ball 350 is embedded in the positioning groove 1123. Under the combined action of the locking post 340, the second elastic element 330 and the spring ball 350, the retainer 112 can return to the first position and remain in the first position under the condition of no external force.

[0058] In some embodiments, the transmission surface 211 of the inner ring portion 210 can be a smooth arc surface; in other embodiments, please refer to... Figure 2 and Figure 4 The transmission surface 211 of the inner ring 210 can also be a toothed surface. The specifications and dimensions of the tooth structure of the transmission surface 211 can be adjusted to accommodate the situation, as long as the transmission surface 211 can smoothly abut against one end of the swing block 310.

[0059] In some embodiments, please refer to Figures 4-7The mounting groove 113 is provided with a positioning cam 114 co-oriented with the first rotation axis. Each swing block 310 is provided with a mounting hole 311 through which the positioning cam 114 passes. Each swing block 310 is positioned in the mounting groove 113 by a positioning cam 114. The positioning cam 114 is a feasible implementation of a fixing structure and can limit the swing block to a certain extent. In the embodiment where the swing block 310 can be driven to swing by the retainer 112, each swing block 310 can swing around the corresponding positioning cam 114 when driven by the retainer 112. Each swing block 310 is coarsely positioned by the positioning cam 114. The positioning cam 114 can provide a swing base point for the swing block 310 when driven to swing by the retainer 112, which facilitates the installation of the swing block 310 and the first elastic member 320. At the same time, the positioning cam 114 and the fixing structure work together to effectively prevent the swing block 310 from falling out of the mounting groove 113.

[0060] In some embodiments, please refer to Figure 7 The mounting hole 311 is a waist-shaped hole extending radially along the inner ring portion 210, so that the swing block 310 has a certain swing margin, which can effectively prevent the swing block 310 from jamming with the base 111 and the cage 112 when the cage 112 moves from the first position to the second position. For details, please refer to Figure 7 By setting the mounting hole 311 as an oblong hole, a certain amount of lateral movement can be provided for the swing block 310. When the retainer 112 moves from the first position to the second position, the retainer 112 drives the swing block 310 to swing. At the same time, the swing block 310 can move to a certain extent under the guidance of the positioning cam 114, so that the swing block 310 can adaptively adjust its position when it may have rotational interference with the base 111. Thus, the swing block 310 can swing to a position that does not abut against the transmission surface 211 of the inner ring 210 under the drive of the retainer 112, thereby achieving the purpose of unlocking the inner ring 210 and the outer ring 110.

[0061] In some embodiments, please refer to Figure 6 and Figure 7 The locking assembly 300 includes multiple sets of swing blocks 310 and a number of first elastic members 320 equal to the number of swing blocks 310. The swing blocks 310 and the first elastic members 320 are assembled in a one-to-one correspondence. The multiple sets of swing blocks 310 are arranged at intervals along the circumference of the outer ring portion 110 to provide sufficient locking force so that the inner ring portion 210 and the outer ring portion 110 can still be stably locked when the monitor is being supported, which helps to improve the stability of the monitor bracket.

[0062] In some embodiments, please refer to Figure 6 and Figure 7A set of swing blocks 310 includes one swing block 310 or two swing blocks 310. When a set of swing blocks 310 includes two swing blocks 310, the base 111 is provided with mounting grooves 113 on both sides along the first rotation axis. The two swing blocks 310 are arranged opposite each other along the first rotation axis so as to reasonably transmit the oblique shear force generated when the inner ring 210 rotates through multiple sets of swing blocks 310, ensuring the smooth use of the monitor bracket. At the same time, multiple swing blocks 310 can lock the inner ring 210 and the outer ring 110 at the same time, which can effectively improve the stability of the monitor bracket.

[0063] In some embodiments, please refer to Figure 4 , Figure 6 and Figure 7 The first elastic element 320 is a spring. The swing block 310 has a relief groove 312 on one side to accommodate one end of the first elastic element 320. The mounting groove 113 of the base 111 also has a receiving groove to accommodate the other end of the first elastic element 320. The receiving groove is connected to the mounting groove 113, so that the swing block 310 and the first elastic element 320 can be installed more quickly and conveniently, which can further reduce the difficulty of product assembly.

[0064] In some embodiments, please refer to Figure 1 The support arm 100 also includes a main arm 130 rotatably connected to the connector 120. The number of main arms 130 can be at least two. When the support arm 100 includes at least two main arms 130, each main arm 130 is sequentially and movably connected. Increasing the number of main arms 130 improves the range of motion and freedom of the monitor mount 200, further enhancing the adjustability of the monitor stand.

[0065] In some embodiments, please refer to Figure 1 The connecting part is a connecting seat 400 that is rotatably connected to the support arm 100. The connecting seat 400 is used to fix the display bracket to the mounting base. In different embodiments, depending on the different mounting bases in the application scenario, the connecting seat 400 can have various configuration forms. For example, in some embodiments, the mounting base can be a support rod or column on a director's vehicle, in which case the connecting seat 400 can be a pipe clamp. For example, please refer to Figure 1The pipe clamp is integrally mounted on one end of the support arm 100. The pipe clamp includes a fixed part 410, a movable part 420, and a clamping wrench 430. One end of the movable part 420 is hinged to the fixed part 410, and the other end of the movable part 420, as a movable end, is connected to the fixed part 410 via the clamping wrench 430. The movable part 420 and the fixed part 410 together form a clamping cavity 440. After the support rod or column is inserted into the clamping cavity 440, the movable part 420 is locked by adjusting the clamping wrench 430, thereby clamping the support rod or column within the clamping cavity 440, thus completing the clamping installation. In other embodiments, other pipe clamp structures can also be used, and the pipe clamp can also be a separate structure from the support arm 100, as long as it can be fixed to the support arm 100.

[0066] In other embodiments, the mounting base can also be a desktop or panel, in which case the connector 400 can be a desktop clip. For example, please refer to... Figure 9 If the desktop or board surface has mounting holes 311, the connector 400 can use a through-hole mounting desktop clamp 450. This desktop clamp includes a through-hole post and two clamping locking elements mounted on the through-hole post. The through-hole post is passed through the through-hole in the desktop or board surface, and the clamping locking elements are adjusted to clamp the desktop or board surface in the middle, thus completing the installation and fixing of the connector 400. Please refer to... Figure 10 If it needs to be installed on the edge of a desktop or board, the connector 400 can be a clamshell-mounted desktop clamp 460 with a clamping opening. That is, the desktop clamp includes a C-shaped clamping member, with a clamping opening formed on one side of the C-shaped clamping member. The C-shaped clamping member is provided with set screws on one 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 set screws are adjusted to clamp the desktop or board in the clamping opening.

[0067] In summary, the monitor stand provided by this utility model has at least the following beneficial effects:

[0068] Simply place the swing block 310 in the mounting groove 113 on the side of the base 111, align the swing block 310 with the positioning cam 114, and install one end of the first elastic member 320 in the receiving groove, with the other end of the first elastic member 320 abutting against the swing block 310, thus completing the assembly of the locking assembly 300 and the base 111. Then, the retainer 112 is installed on the base 111, so that the two wings 1121 of the retainer 112 clamp the locking component 300 and the base 111. At this time, the assembly of the locking component 300 and the outer ring 110 is completed. Afterwards, only the monitor mounting base 200 and the bracket arm 100 need to be assembled to make the locking component 300 stably arranged between the inner ring 210 and the outer ring 110. The swing block 310 can lock or unlock the inner ring 210 and the outer ring 110. The assembly scheme between the locking component 300, the inner ring 210 and the outer ring 110 is simple and facilitates the assembly of the monitor bracket.

[0069] On the one hand, the addition of a locking component 300 to the monitor stand effectively solves the current technical problem of unstable monitor fixation. On the other hand, based on the locking function of the monitor stand, by designing and coordinating the various structural parts of the monitor stand accordingly, the assembly scheme of the monitor stand can be simplified, effectively reducing the difficulty of assembly and making it easier to assemble and install the locking component 300, thereby effectively improving the production efficiency of the finished monitor stand.
