Description

Technical Field

[0001] This utility model belongs to the field of television installation technology, and specifically relates to a television single swing arm extension bracket. Background Technology

[0002] In people's daily lives, televisions have become an indispensable audio-visual device, with almost every household equipped with one. As living spaces become increasingly compact and people pursue a high-quality viewing experience, wall-mounted installation has become the first choice for many families due to its advantages such as saving space and improving the tidiness of the space.

[0003] Existing televisions are generally mounted on the wall using a single swing arm extension bracket. The bracket is fixed to the wall with bolts, and the television is then fixed to the mounting frame of the bracket with bolts. The viewing orientation of the television can be adjusted by the relative rotation between the various components.

[0004] However, most existing TV single-arm extension brackets only have angle adjustment functions to adjust the TV's orientation. In actual use scenarios, the height requirements of the TV vary depending on the height of different family members, the application location, viewing habits, and room layout. To achieve the best viewing effect, the TV should be positioned at a relatively suitable height. However, most existing TV single-arm extension brackets cannot adjust the height. Adjusting the height usually requires disassembling or reassembling certain parts of the bracket, which is troublesome and cumbersome, thus reducing the practicality and flexibility of the TV single-arm extension bracket. Utility Model Content

[0005] Most existing single-arm TV extendable stands only offer angle adjustment to control the TV's orientation. However, in real-world use, varying family members' heights, different viewing locations, viewing habits, and room layouts lead to different height requirements for the TV. Positioning the TV at a suitable height ensures optimal viewing. Existing single-arm TV extendable stands often lack height adjustment capabilities, requiring disassembly or reassembly of certain components, which is cumbersome and reduces practicality and flexibility. This invention addresses these issues by proposing a new single-arm TV extendable stand to overcome these problems.

[0011] Furthermore, the front end of the limiting block is engaged into the corresponding slot, the limiting block is slidably connected to the slot, the adjusting rod is hollow inside, and a bolt is threaded onto the right side surface of the adjusting rod. The bolt thread penetrates into the adjusting rod, and one end of the bolt penetrating into the adjusting rod contacts the outer surface of the fixing rod.

[0012] Furthermore, the second adjusting mechanism includes a second rotating block, which is fixedly connected to the end of the adjusting rod away from the fixed rod. Support columns are fixedly connected to the outer surfaces of both sides of the second rotating block. Rotating rings are rotatably sleeved on the outer surfaces of the support columns. Connecting rods are fixedly connected to the outer surfaces of the rotating rings. The ends of the two connecting rods away from the rotating rings are fixedly connected to the mounting bracket. The second rotating block is rotatably connected between the two rotating rings.

[0013] Furthermore, the outer surface of each support column is provided with multiple adjustment holes, which are arranged in a central array.

[0031] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0033] Please see Figures 1-7 As shown, this utility model is a television single swing arm extension bracket, including a fixed base 1. A rotating frame 2 with a vertical cross-section in the shape of a "U" is fixedly connected to the front surface of the fixed base 1. A first rotating block 3 is rotatably connected between two vertical blocks of the rotating frame 2. An adjusting base 5 is fixedly connected to the outer surface of the first rotating block 3. A fixed rod 7 is provided on the adjusting base 5. An adjusting rod 8 is slidably sleeved on the fixed rod 7. A mounting bracket 13 is provided at the end of the adjusting rod 8 away from the adjusting base 5. The television is fixed to the mounting bracket 13 by bolts. A first adjusting mechanism is provided on the adjusting base 5, which can adjust the height of the television. A second adjusting mechanism is provided on the mounting bracket 13, which is located at the end of the adjusting rod 8 away from the fixed rod 7. The second adjusting mechanism is used to adjust the angle of the television.

[0034] By mounting the television set with bolts on one side of the mounting bracket 13, when the vertical tilt angle of the television set needs to be adjusted, the mounting bracket 13 is rotated to allow it to rotate vertically in conjunction with the second adjustment mechanism. When the distance between the television set and the viewing position needs to be adjusted, the mounting bracket 13 is pulled, causing the second adjustment mechanism to pull the adjustment rod 8, which moves the inner part of the adjustment rod 8 along the direction of the fixed rod 7. When the orientation of the television set needs to be changed, the mounting bracket 13 is rotated left or right, causing the second adjustment mechanism to move the adjustment rod 8, which in turn moves the internally fitted fixed rod 7, thereby causing the fixed rod 7 to move the adjustment seat 5. The adjustment seat 5 is fixedly connected to the outer surface of the first rotating block 3, and the first rotating block 3 is rotatably connected to the two vertical blocks of the rotating frame 2. Therefore, when the adjustment seat 5 moves, it can drive the first rotating block 3 to rotate around the rotating frame 2, thereby causing the mounting frame 13 to drive the television to move in a circle around the rotating frame 2, so as to adjust the orientation of the television. When it is necessary to adjust the height of the television, by pushing the mounting frame 13 upward, it can cooperate with the second adjustment mechanism to drive one end of the adjustment rod 8 to move upward, and the other end of the adjustment rod 8 to drive one end of the fixed rod 7 to move upward, thereby causing the other end of the fixed rod 7 to drive the adjustment seat 5 to move upward, so that the adjustment seat 5 drives the first adjustment mechanism to operate, thereby limiting and fixing the movement position, so as to cooperate with the mounting frame 13 to adjust the height of the television.

[0035] In one embodiment, the first adjustment mechanism includes two fixed columns 4, which are fixedly connected to the upper and lower outer surfaces of the first rotating block 3. The upper surfaces of the two vertical blocks of the rotating frame 2 are provided with rotating holes extending out of their lower surfaces. The two fixed columns 4 are rotatably connected to the two rotating holes, and rubber friction rings are provided in the rotating holes.

[0036] The front surface of the adjusting seat 5 is provided with a connecting groove 20. A rotating disk 6 is rotatably connected between the inner walls of the left and right sides of the connecting groove 20. A limiting disk 19 is fixedly sleeved on the outer surface of the rotating disk 6. A fixing rod 7 is fixedly connected to the outer surface of the rotating disk 6. The limiting disk 19 is fixedly connected to the fixing rod 7. The fixing rod 7 slides out of the outer surface of the adjusting seat 5 through the connecting groove 20. A limiting groove 22 is provided on the rear inner wall of the connecting groove 20. A limiting block 23 is slidably connected in the limiting groove 22. The front surface of the limiting block 23 is inclined.

[0037] The outer surface of the limiting disk 19 is provided with a plurality of slots 26 arranged in a central array. The slots 26 extend out of the left and right outer surfaces of the limiting disk 19. Two support springs 25 are fixedly connected to the rear inner wall of the limiting groove 22. The front ends of the support springs 25 are fixedly connected to the rear surface of the limiting block 23. The left and right outer surfaces of the adjusting seat 5 are provided with fixing grooves 21. The fixing grooves 21 communicate with the interior of the limiting groove 22. Push blocks 24 are fixedly connected to the left and right outer surfaces of the limiting block 23. The push blocks 24 are slidably connected to the corresponding fixing grooves 21. The outer surface of the push block 24 away from the limiting block 23 extends out of the outer surface of the adjusting seat 5 through the corresponding fixing grooves 21.

[0038] The front end of the limiting block 23 is engaged in the corresponding slot 26, and the limiting block 23 is slidably connected to the slot 26. The adjusting rod 8 is hollow inside, and a bolt 18 is threadedly connected to the right side surface of the adjusting rod 8. The bolt 18 is threaded through the adjusting rod 8, and one end of the bolt 18 that penetrates the adjusting rod 8 contacts the outer surface of the fixing rod 7.

[0039] Furthermore, in practical applications, in the initial state, with the cooperation of the limiting plate 19, the slot 26, the support spring 25, and the limiting block 23, the limiting block 23 engages with the slot 26, restricting the limiting plate 19 so that it can only rotate clockwise and not counterclockwise, thus supporting the television and preventing it from falling due to gravity. When the television or mounting bracket 13 is pushed upwards, the television will rotate around the rotating plate 6. During this process, the limiting plate 19 exerts a pushing force on the inclined surface of the limiting block 23 through the slot 26, thereby pushing the limiting block. 23 moves backward, during which the support spring 25 is compressed and deformed. When the TV moves upward to a suitable height, the release force of the support spring 25 pushes the limiting block 23 to slide into the appropriate slot 26, thereby limiting the limiting plate 19 and positioning the height of the TV to prevent it from falling downward under the force of gravity. Pushing the TV upward can adjust the height of the TV, which is convenient and flexible, thus increasing the practicality and flexibility of the TV single swing arm extension bracket.

[0040] When the height of the TV needs to be adjusted downwards, first push the push block 24, causing the push block 24 to slide the limiting block 23 out of the slot 26. At this time, the restriction on the limiting plate 19 is released, allowing the limiting plate 19 to rotate clockwise and counterclockwise. Then, the fixing rod 7 and the adjusting rod 8 are rotated counterclockwise, which in turn moves the TV downwards. After adjusting to the appropriate height, release the push block 24. Under the action of the release force of the support spring 25, the limiting block 23 is slid into the appropriate slot 26, thus supporting and restricting the TV again. The operation is convenient and flexible, allowing the TV to be displayed at different heights to meet different needs, thereby increasing the practicality and flexibility of the TV single swing arm extension bracket.

[0041] In one embodiment, the second adjustment mechanism includes a second rotating block 9, which is fixedly connected to the end of the adjustment rod 8 away from the fixed rod 7. Support columns 12 are fixedly connected to the outer surfaces of both sides of the second rotating block 9. Rotating rings 10 are rotatably sleeved on the outer surfaces of the support columns 12. Connecting rods 11 are fixedly connected to the outer surfaces of the rotating rings 10. The ends of the two connecting rods 11 away from the rotating rings 10 are fixedly connected to the mounting bracket 13. The second rotating block 9 is rotatably connected between the two rotating rings 10.

[0042] The outer surface of each support column 12 is provided with a plurality of adjustment holes 16, which are arranged in a central array. The outer surface of each rotating ring 10 is slidably connected with a limit rod 17. The lower end of the limit rod 17 slides into the rotating ring 10. The lower surface of the limit rod 17 is hemispherical in shape. The limit rod 17 is adapted to fit the adjustment holes 16.

[0043] The lower end of the limiting rod 17 extends into the adjusting hole 16. The limiting rod 17 is slidably connected to the adjusting hole 16. The upper end of the limiting rod 17 is fixedly connected to a positioning block 14. A tension spring 15 is fixedly connected between the positioning block 14 and the rotating ring 10. The tension spring 15 is slidably sleeved on the outer surface of the limiting rod 17.

[0044] In the initial state, under the action of the two tension springs 15, the lower end of the limiting rod 17 slides into the adjustment hole 16 to restrict and support the television. This ensures that, without external force, the friction between the lower end of the limiting rod 17 and the adjustment hole 16 is sufficient to support the television and maintain its current state, preventing rotation around the support column 12. When adjusting the height of the television and then adjusting its tilt angle, the mounting bracket 13 can be pushed. The mounting bracket 13 then applies a thrust to the rotating ring 10. Under this external force, the adjustment hole 16 pushes the lower end of the limiting rod 17, causing the limiting rod 17 to slide upwards out of the current adjustment hole. Within 16, the rotating ring 10 rotates around the support column 12. During this process, the tension spring 15 is stretched, causing it to deform. Under the release force of the tension spring 15, the limiting rod 17 is pushed into the adjacent adjustment hole 16 until the tilt angle of the TV is adjusted. At this point, the limiting rod 17 slides into the appropriate adjustment hole 16. To adjust the tilt angle of the TV, simply push the mounting bracket 13 to rotate the TV around the support column 12. The operation is convenient and quick, allowing the TV to have multiple tilt angles, increasing the practicality and flexibility of the TV single swing arm extension bracket.

[0045] In this design, rotating bolt 18 causes one end of bolt 18, which penetrates into adjusting rod 8, to make tight contact with the outer surface of fixed rod 7, thereby increasing the friction between fixed rod 7 and bolt 18, thus fixing fixed rod 7 and adjusting rod 8. By adjusting the length of fixed rod 7 extending to adjusting rod 8, the front and rear positions of the TV can be adjusted, thereby adjusting the distance between the TV and the viewing position. On the other hand, the range of height adjustment of the TV can be increased, thereby increasing the practicality of the TV single swing arm extension bracket.

[0046] In this design, by rotating the fixed rod 7 or the adjusting rod 8, the adjusting seat 5 can rotate around the fixed column 4, thereby adjusting the orientation of the TV and making the TV single swing arm extension bracket more flexible.

[0047] In summary, with the help of the above-mentioned technical solution of this utility model, in the initial state, under the combined action of the limiting plate 19, the slot 26, the supporting spring 25, and the limiting block 23, the limiting block 23 engages with the slot 26, restricting the limiting plate 19 so that it can only rotate clockwise and not counterclockwise, thus supporting the television and preventing it from falling due to gravity. When the television or mounting bracket 13 is pushed upward, the television will rotate around the rotating plate 6. During this process, the limiting plate 19 pushes the inclined surface of the limiting block 23 through the slot 26, pushing the limiting block 23 backward. During this process, the support spring 25 is compressed, causing it to deform. When the television moves upward to a suitable height, the release force of the support spring 25 pushes the limiting block 23 into the appropriate slot 26, thereby limiting the limiting plate 19 and positioning the height of the television to prevent it from falling downwards due to gravity. Pushing the television upwards allows for height adjustment. When the height needs to be adjusted downwards, the push block 24 is pushed, causing it to slide the limiting block 23 out of the slot 26. This releases the restriction on the limiting plate 19, allowing it to move freely. The device rotates clockwise and counterclockwise, thereby rotating the fixed rod 7 and adjusting rod 8 counterclockwise, which in turn moves the television downwards. After adjusting to a suitable height, the push block 24 is released. Under the release force of the support spring 25, the limiting block 23 slides into the appropriate slot 26, thus supporting and limiting the television again. Under the action of the two tension springs 15, the lower end of the limiting rod 17 slides into the adjusting hole 16 to limit and support the television. This ensures that, without external force, the friction between the lower end of the limiting rod 17 and the adjusting hole 16 is sufficient to support the television and maintain its current state, preventing it from collapsing against the support column. The rotating ring 10 rotates around the support column 12. When the height of the TV needs to be adjusted and the tilt angle needs to be adjusted, the mounting bracket 13 can be pushed. The mounting bracket 13 pushes the rotating ring 10. Under the application of external force, the adjustment hole 16 pushes the lower end of the limiting rod 17, pushing the limiting rod 17 to slide upward out of the current adjustment hole 16. This causes the rotating ring 10 to rotate around the support column 12. During this process, the tension spring 15 is stretched, causing the tension spring 15 to deform. Under the action of the release elasticity of the tension spring 15, the limiting rod 17 is pushed to slide into the adjacent adjustment hole 16 until the tilt angle of the TV is adjusted.

[0048] Through the above technical solution, 1. by the release force of the support spring 25, the limiting block 23 is driven to slide into the appropriate slot 26, thereby supporting and limiting the TV again. The operation is convenient and flexible, so that the TV can be displayed at different heights, thereby meeting different needs and increasing the practicality and flexibility of the TV single swing arm extension bracket.

[0049] 2. The height of the TV is positioned by the release force of the support spring 25, preventing the TV from falling downwards due to gravity. The height of the TV can be adjusted by pushing it upwards. The height adjustment is convenient and flexible, thus increasing the practicality and flexibility of the TV single swing arm extension bracket.

[0050] 3. By sliding the limiting rod 17 into the appropriate adjustment hole 16, the tilt angle of the TV can be adjusted. Simply push the mounting bracket 13 to make the TV rotate around the support column 12. The operation is convenient and quick, allowing the TV to have multiple tilt angles, increasing the practicality and flexibility of the TV single swing arm extension bracket.

[0051] 4. By adjusting the length of the adjusting rod 8 extending from the fixed rod 7, the front and back positions of the TV can be adjusted, thereby adjusting the distance between the TV and the viewing position. On the other hand, the range of height adjustment of the TV can be increased, thus increasing the practicality of the TV single swing arm extension bracket.
