Description

Technical Field

[0001] This utility model relates to the field of television bracket technology, specifically a television bracket rotation mechanism. Background Technology

[0002] A TV stand is a support device specifically designed for flat-screen TVs and LCD TVs. It is used to fix the TV to the wall or the floor and is widely used in homes, offices, and commercial settings.

[0003] In the design of rotatable stands for devices such as televisions and monitors, the rotation mechanism is a key component that enables the screen to rotate horizontally to accommodate different viewing angles.

[0004] However, most existing TV bracket rotation mechanisms lack mechanical limits or only use simple stop blocks for limiting. The former may cause excessive twisting of cables and damage, while the latter is prone to generating severe impacts and noise. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a television bracket rotation mechanism for achieving smooth horizontal rotation and reliable positioning of a television set, thus solving the problems mentioned in the background section.

[0015] (III) Beneficial Effects

[0016] This utility model provides a television bracket rotation mechanism. It has the following beneficial effects:

[0017] 1. The TV bracket rotation mechanism achieves positioning by rolling steel balls within a closed track composed of annular grooves and limiting arc grooves. This method provides a smooth transition, avoiding the impact and noise caused by block-type positioning, resulting in a better user experience. Furthermore, by flexibly designing the central angles of the annular grooves and limiting arc grooves, the total rotation angle can be precisely controlled, meeting the needs of large-angle adjustment while effectively preventing cable breakage, ensuring safety and reliability.

[0018] 2. The TV bracket rotation mechanism, through the setting of elastic damping components, can change the compression of the elastic damping components by simply adjusting the axial fasteners with tools. This change in compression is directly converted into positive pressure on the end face of the central shaft, thereby linearly changing the rotation damping. This allows the rotation tightness to be easily adjusted to the optimal state according to the weight of the TV and personal feel preference, making it more versatile.

[0019] 3. The TV bracket rotation mechanism, through its split connector design, effectively increases the flexibility of the structure, making it easy to adapt to different installation scenarios and easy to assemble and maintain. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] This utility model embodiment provides a television bracket rotation mechanism, such as Figure 1-6 As shown, it includes a connecting seat for fixing to the support column and a rotating assembly set on the connecting seat. The rotating assembly includes a coupling seat 4, a central shaft 12, and a copper sleeve 8. The copper sleeve 8 is fixedly connected to the connecting seat, and the central shaft 12 is fixedly connected to the bottom of the coupling seat 4. The central shaft 12 is rotatably connected to the copper sleeve 8.

[0029] A limiting component is provided between the opposite surfaces of the coupling seat 4 and the connecting seat. The limiting component includes a steel ball 6, an annular groove 5 and a limiting arc groove 7. The annular groove 5 is opened on one of the coupling seat 4 or the connecting seat, and the limiting arc groove 7 is opened on the other. The steel ball 6 is housed in a closed track formed by the annular groove 5 and the limiting arc groove 7.

[0030] In some embodiments, such as Figure 2-3 As shown, the limiting arc-shaped groove 7 is formed on the bottom surface of the coupling seat 4 facing the connecting seat. The annular groove 5 is formed on the top surface of the fixing plate 3 of the connecting seat facing the coupling seat 4.

[0031] The central angle of the annular groove 5 is greater than 300 degrees, and the central angle of the limiting arc groove 7 is less than 60 degrees. The limiting arc groove 7 and the annular groove 5 together form a complete limiting track with a maximum angle of 360 degrees.

[0032] In some embodiments, such as Figure 2-3As shown, the central angle of the annular groove 5 is 330 degrees, and the central angle of the limiting arc groove 7 is 30 degrees. Together, they form a complete 360-degree circular limiting track.

[0033] The limiting mechanism is achieved by the steel ball 6 rolling within a closed track formed by the annular groove 5 and the limiting arc groove 7. This method provides a smooth transition, avoiding the impact and noise caused by the block-type limiting mechanism, resulting in a better user experience. Furthermore, by flexibly designing the central angle of the annular groove 5 and the limiting arc groove 7, the total rotation angle can be precisely controlled, which can meet the needs of large-angle adjustment while effectively preventing cable breakage, ensuring safety and reliability.

[0034] The copper sleeve 8 is provided with an elastic damping assembly for adjusting rotational damping. The elastic damping assembly includes an axial fastener 9, a flat washer 10, and an elastic damping element 11. The flat washer 10 is located at the bottom of the copper sleeve 8, and the elastic damping element 11 is located between the flat washer 10 and the axial fastener 9. By adjusting the axial fastener 9, the compression of the elastic damping element 11 can be changed, thereby adjusting the damping of the rotation of the central shaft 12.

[0035] By adjusting the axial fastener 9 using the set elastic damping component, the compression of the elastic damping component 11 can be changed. This change in compression is directly converted into a positive pressure on the end face of the central shaft 12, thereby linearly changing the rotational damping. This allows the rotational tightness to be easily adjusted to the optimal state according to the weight of the TV and personal hand feel preferences, making it more versatile.

[0036] The axial fastener 9 is a flat-head screw, and the center shaft 12 has a screw hole in the center. The axial fastener 9 is threaded into the screw hole of the center shaft 12.

[0037] In some embodiments, such as Figure 3-6 As shown, the axial fastener 9 is preferably a flat-head screw, which is screwed into the screw hole at the end of the central shaft 12. By tightening or loosening the flat-head screw, the pressure of the flat washer 10 on the bottom of the copper sleeve 8 can be changed, and the amount of compression deformation of the elastic damping element 11 can be changed, thereby realizing the adjustment of rotational damping.

[0038] Tightening the screw clockwise increases damping and makes rotation tighter; loosening the screw counterclockwise decreases damping and makes rotation looser.

[0039] The elastic damping element 11 is set as a spring washer.

[0040] The connector includes a connecting plate 1, a transition plate 2, and a fixing plate 3. The top of the connecting plate 1 is fixedly connected to the transition plate 2, and the top of the transition plate 2 is fixedly connected to the fixing plate 3. The copper sleeve 8 is press-fitted or bonded into the central circular hole of the fixing plate 3 of the connector.

[0041] The fixing plate 3 has a first mounting hole, and the transition plate 2 has a first screw hole corresponding to the first mounting hole. The fixing plate 3 and the transition plate 2 are fixedly connected by screws.

[0042] The transition plate 2 has a second mounting hole, and the connecting plate 1 has a second screw hole corresponding to the second mounting hole. The transition plate 2 and the connecting plate 1 are fixedly connected by screws.

[0043] During installation, the rotating component can be installed on the fixed plate 3 first, then the connecting plate 1 and the transition plate 2 can be installed on the TV stand, and finally the two parts can be combined and installed, thereby improving installation efficiency.

[0044] The modular connector design effectively increases structural flexibility, making it easy to adapt to different installation scenarios and facilitating assembly and maintenance.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
