[0002] The display device stand can allow the computer screen and other display devices to float on the desktop, which is more beautiful. It can also free the display device from the constraints of the display base and achieve true 360° all-round adjustment. It can also reduce the occupation of desktop space and increase the usable space on the desktop. It is a good partner for many home workers or students.

[0003] However, the existing display device stands have the following defects: the single-arm display device stands on the market usually have a fixed connection or simply clamped connection between the base and the support rod. The fixed connection makes it difficult to disassemble and adjust the base and the support rod, increasing the difficulty of logistics and transportation, thereby increasing costs. In addition, when the forward inclination angle of the support rod is fixed, the height of the display device cannot be adjusted by changing the installation height of the support rod on the base, and the usage scenarios are relatively limited. The clamping fixation form will cause the support rod to slide down during use. Summary of the invention

[0010] In some embodiments, the abutment portion and the limiting ring are integrally formed and connected, and are cut off between the movable end and the limiting ring.

[0011] In some embodiments, the shape of the abutment portion close to the support column is matched with the shape of the outer surface of the support column.

[0026] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0028] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0029] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0030] The present application is further described below with reference to the accompanying drawings:

[0031] like Figures 1 to 10 As shown, the present application provides a limiting mechanism, and the display device bracket includes a supporting component 1 and a connecting component 2, and the supporting component 1 and the connecting component 2 are rotatably connected. The supporting component 1 is usually used to be fixed to the surface of the supporting object, and the connecting component 2 is usually used to be connected and fixed with the display device. By utilizing the rotatable connection between the connecting component 2 and the supporting component 1, the display direction of the display device can be conveniently adjusted, so that the user can adjust the viewing angle of the display device at will, thereby improving the viewing comfort.

[0032] The support assembly 1 includes a support rod 11 and a support seat 12. The two ends of the support rod 11 are respectively connected to the support seat 12 and the connecting assembly 2. The support seat 12 is usually used to be fixed to the surface of the support object, and the support rod 11 is used to support the display device in the extension direction to achieve the position movement of the display device.

[0033] like Figure 1 In the illustrated embodiment, the main structure of the support base 12 is L-shaped, and the support base 12 is provided with a mounting hole 122 at least on a side surface, and the support base 12 can be fixed to a supporting surface such as a wall through the mounting hole 122 .

[0034] A support column 121 is provided on the support seat 12, and the support rod 11 is suitable for sliding or fixing along the support column 121. By using the support column 121, the entire support rod 11 can be moved along the length direction of the support column 121, thereby improving the maximum adjustable range of the entire display device bracket.

[0035] A limiting mechanism 3 is provided on the support column 121, and the limiting mechanism 3 is suitable for limiting the support rod 11 from sliding toward one side of the limiting mechanism 3, so that the support rod 11 can be stably on the support column 121. Due to the adjustable position of the support rod 11 on the support column 121 and for the convenience of adjustment, in actual applications the support rod 11 is usually in the form of a clamp connection, and this structure may be difficult to maintain a stable state of the support rod 11 under long-term stress. Therefore, by providing the limiting mechanism 3, the position of the support rod 11 on the support column 121 can be effectively supported to avoid the support rod 11 from slipping, thereby improving the stable support for the display device.

[0036] like Figures 2 to 4 In the illustrated embodiment, the limiting mechanism 3 includes a limiting ring 31, a positioning block 32 and a fastener 33. The limiting ring 31 is sleeved on the support column 121. At least one first installation channel 311 is opened on the limiting ring 31. The limiting ring 31 is provided with a resistance portion 34 on the side of the first installation channel 311 close to the support column 121. The positioning block 32 is suitable for being embedded in the first installation channel 311 in a one-to-one manner. The fastener 33 is suitable for limiting the positioning block 32 in the first installation channel 311 and abutting against the resistance portion 34. The fastener 33 is suitable for moving relative to the positioning block 32 so that the resistance portion 34 moves relative to the limiting ring 31 at least along the radial direction of the support column 121, and abuts against the resistance portion 34. The contact portion 34 can not only protect the surface of the support column 121 and reduce wear, but also increase the contact area between the limit ring 31 and the support column 121, thereby increasing the static friction and reducing the probability of the limit ring 31 being displaced under the pressure of the support rod 11. The positioning block 32 can improve the matching stability between the fastener 33 and the resistance portion 34, so that the fastener 33 can continuously and stably press the resistance portion 34 to contact the surface of the support column 121. In addition, since there is more force between the positioning block 32 and the fastener 33, the probability of structural damage is relatively high. Therefore, the setting of the positioning block 32 and the fastener 33 can facilitate maintenance and reduce replacement costs.

[0037] In some embodiments, the first installation channel 311 is opened along the axial direction of the limiting ring 31 , which can facilitate the positioning block 32 to be inserted into the first installation channel 311 from the side of the limiting ring 31 .

[0038] In some embodiments, the first installation channel 311 is opened through the limiting ring 31, so that the positioning block 32 can be inserted from both the upper and lower sides of the limiting ring 31, which can improve the convenience of installation.

[0039] like Figures 2 to 4 In the illustrated embodiment, the limiting ring 31 is provided with a second mounting channel 312 for the fastener 33 to pass through on the side of the first mounting channel 311 away from the support column 121. The second mounting channel 312 is connected to the first mounting channel 311. The fastener 33 is suitable for passing through the second mounting channel 312 and the positioning block 32 and then abutting against the abutment portion 34. When the fastener 33 passes through the second mounting channel 312 and is connected to the positioning block 32, at least part of the fastener 33 is located in the second mounting channel 312. The fastener 33 can limit the positioning block 32 from being separated from the first mounting channel 311, thereby further improving the structural stability.

[0040] In some embodiments, the connection between the fastener 33 and the positioning block 32 is in the form of a threaded screw, which can improve the stability of the fastener 33 and the positioning block 32 after relative movement occurs.

[0041] like Figure 3 In the illustrated embodiment, the second installation channel 312 is opened along the radial direction of the limiting ring 31, which can facilitate the matching of the fastener 33 and the positioning block 32, and at the same time has high matching stability and is not prone to movement.

[0042] like Figure 2 In the illustrated embodiment, an operating portion 331 is provided on the fastener 33 , and the operating portion 331 is exposed in the second installation channel 312 . The operating portion 331 is preferably in the form of a hexagonal screw hole, etc., which can achieve a hidden installation effect.

[0043] like Figure 5 In the illustrated embodiment, the abutment portion 34 includes a fixed end 341 and a movable end 342. The fixed end 341 is fixedly connected to the limiting ring 31. The abutment portion 34 is suitable for deformation so that the fixed end 341 and the movable end 342 can move relative to each other. The contact portion can be deformed under the pressure of the fastener 33, so that the movable end 342 can abut against the surface of the support column 121, thereby generating a larger static friction force. Moreover, by increasing the pressure force of the fastener 33, the static friction force can be increased to enhance the fixing effect.

[0044] In some embodiments, the deformation of the abutment portion 34 can be restored, so that the limiting ring 31 can be easily disassembled and reassembled.

[0045] like Figure 4 In the illustrated embodiment, the width of the positioning block 32 is greater than the width of the movable end 342 , ensuring that the positioning block 32 is fixed on the limiting ring 31 and does not move with the movable end 342 .

[0046] like Figure 4In the illustrated embodiment, the width of the fastener 33 is not greater than the width of the movable end 342 , ensuring that the fastener 33 does not interfere with structures other than the movable end 342 .

[0047] In some embodiments, the width of the fastener 33 is slightly smaller than the width of the movable end 342 , and the fastener 33 can compress the movable end 342 more integrally, thereby increasing the friction between the movable end 342 and the surface of the support column 121 .

[0048] like Figure 5 In the embodiment shown, the abutment portion 34 and the limiting ring 31 are integrally formed and connected, and the contact portion is cut off between the movable end 342 and the limiting ring 31, which can improve the connection stability between the abutment portion 34 and the limiting ring 31, reduce the probability of loss of the abutment portion 34, and also reduce the number of parts.

[0049] like Figure 4 In the illustrated embodiment, the shape of the side of the abutment portion 34 close to the support column 121 is matched with the shape of the outer surface of the support column 121 .

[0050] In some embodiments, the support column 121 is cylindrical, which can facilitate the rotation between the support rod 11 and the support column 121 , and the shape of the interference portion 34 close to the support column 121 is an arc.

[0051] like Figure 4 In the illustrated embodiment, the number of the abutment portions 34 is at least two, and the angle between the line connecting two adjacent abutment portions 34 and the central axis of the support column 121 is not less than 90°, which can further increase the abutment area between the limit ring 31 and the support column 121, thereby increasing the static friction, dispersing the force, and effectively reducing the probability of movement of the limit ring 31.

[0052] like Figure 6 In the illustrated embodiment, a wire harness mechanism 4 is provided on the support rod 11, and a wire harness channel 41 is opened on the wire harness mechanism 4 along the length direction of the support rod 11. The wire harness mechanism 4 can be a semi-enclosed structure with openings at both ends and sides, and can be closed to form the wire harness channel 41 by cooperating with the support rod 11. It can also be directly set as a closed structure with openings only at both ends to directly form the wire harness channel 41.

[0053] A first fixing opening 111 and a second fixing opening 112 are provided on the support rod 11, and a first fixing portion 42 and a second fixing portion 43 are provided on the wiring harness mechanism 4. The first fixing portion 42 is suitable for sliding along the first fixing opening 111, and the second fixing portion 43 is suitable for sliding along the second fixing opening 112. The first fixing portion 42 is suitable for being clamped with the first fixing opening 111 in a first direction, so that the second fixing portion 43 and the second fixing opening 112 are clamped with each other in the second direction. The first fixing portion 42 is suitable for being deformed to release the clamping with the first fixing opening 111, and the first fixing portion 42 and the second fixing portion 43 are mutually linked to enter a fixed state, so that the first fixing portion 42 and the second fixing portion 43 can cooperate and lock with each other, so that the wiring harness mechanism 4 is more stably installed on the support rod 11, effectively reducing the probability of the wiring harness mechanism 4 falling off, and the installation operation process is simple and convenient.

[0054] It is worth noting that the first direction in the embodiments of the present application refers to the length direction of the support rod 11. When the first fixing portion 42 and the first fixing port 111 are clamped together, the first fixing portion 42 and the first fixing port 111 cannot be separated in the length direction of the support rod 11. The second direction in the embodiments of the present application refers to the direction perpendicular to the length direction of the support rod 11. When the second fixing portion 43 and the second fixing port 112 are clamped together, the first fixing portion 42 and the first fixing port 111 cannot be separated in the length direction perpendicular to the support rod 11.

[0055] like Figure 7 In the illustrated embodiment, the first fixing opening 111 is provided with a positioning portion 113 along the first direction, the positioning portion 113 is suitable for separating the first fixing opening 111 into a connection area 1111 and a fixing area 1112, and the first fixing portion 42 is suitable for deforming to pass through the positioning portion 113, thereby transferring between the connection area 1111 and the fixing area 1112. It can be understood that after the first fixing portion 42 enters the fixing area 1112, the first fixing portion 42 and the first fixing opening 111 can be snap-connected in the first direction.

[0056] In some embodiments, the length of the connection area 1111 is not less than the length of the first fixing portion 42, that is, it can ensure that the first fixing portion 42 can extend from the connection area 1111 into the first fixing port 111, thereby ensuring that at this time, the second fixing portion 43 can also extend into the second fixing port 112 together, reducing the probability of structural interference.

[0057] In some embodiments, the length of the fixing area 1112 is not less than the length of the first fixing portion 42, that is, it can ensure that the first fixing portion 42 can enter the fixing area 1112 as a whole to achieve clamping, and the activity stroke of the first fixing portion 42 in the fixing area 1112 is less than the clamping depth of the second fixing portion 43 and the second fixing port 112, ensuring that the movement of the first fixing portion 42 in the fixing area 1112 will not cause the clamping relationship between the second fixing portion 43 and the second fixing port 112 to fail, thereby improving the connection stability of the wiring harness mechanism 4.

[0058] like Figure 7 In the illustrated embodiment, a guiding slope 1131 is provided on the side of the positioning portion 113 close to the connection area 1111. The guiding slope 1131 is suitable for guiding the first fixing portion 42 to transfer from the connection area 1111 to the fixing area 1112. The guiding slope 1131 is used to guide the deformation of the first fixing portion 42, thereby reducing the difficulty of operation and making it easier for the first fixing portion 42 to transfer from the connection area 1111 to the fixing area 1112.

[0059] like Figure 7 In the illustrated embodiment, the opening area of ​​the connection region 1111 is larger than the opening area of ​​the fixing region 1112, and an arc-shaped transition is provided between the connection region 1111 and the fixing region 1112 on the opposite side of the positioning portion 113. The main purpose of this design is to reduce the difficulty of operation and to make it easier for the first fixing portion 42 to be transferred from the connection region 1111 to the fixing region 1112.

[0060] In some embodiments, the opening of the connection area 1111 extends toward the deformation direction of the first fixing portion 42 to increase the area, thereby reducing interference in the deformation process of the first fixing portion 42 and lowering the difficulty of operation.

[0061] like Figure 7 In the illustrated embodiment, the number of the second fixing openings 112 is an even number, and the second fixing openings 112 are symmetrically arranged on both sides of the first fixing opening 111 along the length direction of the support rod 11 , which can improve the connection stability of the cable harness mechanism 4 .

[0062] like Figure 7 In the illustrated embodiment, the first fixing portion 42 in the first direction, the first fixing opening 111, the second fixing portion 43 and the second fixing opening 112 form a set of connecting structures, and multiple sets of connecting structures can be arranged on the wiring harness mechanism 4 in the width direction of the support rod 11 to further enhance the connection stability of the wiring harness mechanism 4.

[0063] In some embodiments, the second fixing portion 43 is a hook-shaped structure, so that it can be engaged with the second fixing opening 112 in the second direction while moving with the first fixing portion 42 .

[0064] In some embodiments, a friction structure is provided on the surface of the first fixing portion 42 located on the outer side of the cable harness mechanism 4 to improve the user's operating convenience.

[0065] like Figure 6 In the illustrated embodiment, the friction structure includes a friction strip 421 , which is arranged perpendicular to the matching direction of the first fixing portion 42 and the support rod 11 . The user can use the friction strip 421 to more easily pull the cable tie mechanism 4 into or out of the support rod 11 .

[0066] like Figure 8 In the illustrated embodiment, the support rod 11 includes a clamping portion 114, a connecting rod portion 115 and a rotating portion 116. The clamping portion 114 and the rotating portion 116 are respectively arranged at both ends of the connecting rod portion 115. The clamping portion 114 is suitable for connecting to the support column 121, and the rotating portion 116 is suitable for connecting to the connecting component 2.

[0067] In some embodiments, the clamping portion 114 is a clamping structure, which can be clamped on the support column 121 by bolts and nuts.

[0068] like Figure 8 In the illustrated embodiment, the rotating portion 116 includes a first rotating head 1161, a second rotating head 1162 and a third rotating head 1163 which are sequentially arranged between the connecting rod portion 115 and the connecting component 2, and the rotating planes of the first rotating head 1161, the second rotating head 1162 and the third rotating head 1163 are perpendicular to each other. The rotating portion 116 can enable the display device to rotate 360° after being connected.

[0069] like Figure 8 In the illustrated embodiment, the connecting rod portion 115 includes a first connecting rod 1151 and a second connecting rod 1152. The first connecting rod 1151 and the second connecting rod 1152 are parallel to each other. A top rod 1153 is connected between one end of the first connecting rod 1151 and one end of the second connecting rod 1152. The top rod 1153 can overcome the pressure of the first connecting rod 1151 and the second connecting rod 1152 on the side of the connecting component 2, thereby supporting the display device.

[0070] In some embodiments, the push rod 1153 may be a gas push rod 1153 or a spring push rod 1153 or the like.

[0071] In some embodiments, the connection assembly 2 includes a connection plate 21 and an even number of extension plates 22, the extension plates 22 are suitable for connecting to both sides of the connection plate 21, the extension plates 22 are suitable for extending in at least the third direction and the fourth direction, and are suitable for connecting to the display device.

[0072] like Fig. 9In the embodiment shown, there are two expansion boards, and the main body of the expansion board is a V-shaped structure. After the expansion board is installed on both sides of the connecting plate 21, an X-shaped connecting structure can be formed, which saves space and materials while being able to adapt to the connection of larger display devices as much as possible.

[0073] like Fig.10 In the illustrated embodiment, the connecting plate 21 is connected to the rotating portion 116 by plug-in fitting and is locked by bolts to prevent the connecting plate 21 from being separated. The connecting plate 21 and the expansion plate 22 are connected and locked by multiple sets of bolts and nuts.

Those skilled in the art should understand that the present application is not limited by the above embodiments. The above embodiments and the description only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application.
