[0015] As an alternative of the angle-adjustable TV hanging rack, a second abutting strip is fixed to one side of the rack, a mounting strip is fixed to the rectangular block, and a plurality of arc-shaped abutting blocks are fixed to the mounting strip.

[0016] The angle-adjustable TV hanging rack has the following advantages:

[0017] 1. In the angle-adjustable TV hanging rack, the rotating arm rotatably connected between the mounting frame and the base can be used to flexibly adjust the position of the mounting frame, so that the angle of the TV can be adjusted during installation and viewing. The mounting arm is fixedly connected to the back of the TV, and the mounting arm can be conveniently and directly clamped in the sliding slot of the mounting frame through the rollers, so that the TV can be quickly and preliminarily installed. The mounting arm can be used to drive the TV to move horizontally in the sliding slot to adjust the installation position. The strip-shaped plate can block the sliding slot to reduce the entry of impurities and improve the stability of the movement of the rollers. The limiting block on the strip-shaped plate can limit the position of the rollers after the TV is kept in the middle position on the mounting frame. The cooperation of the positioning insert block, the positioning wedge block, the second guide rod and the first spring can automatically clamp and fix the mounting arm after the position of the mounting arm is adjusted, so that the horizontal movement position of the mounting arm is limited. The locking knob can be used to lock the mounting arm on the mounting frame after the mounting arm is installed in place, so that the child lock function is realized to prevent the TV from falling off the mounting frame due to the accidental touch of children. The number of screws used during the installation of the TV is small, so that the TV can be conveniently and quickly disassembled and assembled, and the disassembly and assembly efficiency can be improved.

[0018] 2. In the angle-adjustable TV hanging rack, the silica gel heat-conducting sheet can be attached to the back of the TV to conduct heat from the inside of the TV to quickly reduce the internal temperature. The heat-conducting sheet can be used to dissipate heat to the air through the heat-dissipating plate. For the TV installed in the background wall, the heat-dissipating plate can increase the heat-dissipating area and reduce the risk of local high temperature, so that the stability of the operation of the TV is improved. The cleaning plate can be used to wipe the local impurities on the back of the TV to improve the adhesion effect of the silica gel heat-conducting sheet.

[0019] The first contact strip on the strip moves down and abuts against the first contact wedge, allowing the cleaning plate to automatically press against the back of the TV. Through the cooperation of the electric push rod, the rectangular block, and the first guide rod, the cleaning plate can be driven to move horizontally to clean the back of the TV. The first and second clamping strips cooperate to clamp the release film on the silicone heat-conducting sheet. During the cleaning process, the release film is automatically separated from the silicone heat-conducting sheet. Under the cooperation of the fifth spring and the guide block, after the cleaning plate has finished cleaning the back of the TV, it can automatically move to one side of the heat sink. When the electric push rod piston rod retracts, the cleaning plate can clean the dust on the surface of the heat sink, thereby improving the heat dissipation effect of the heat sink.

[0020] 3. In this adjustable-angle TV wall mount, several deflectable brushes are installed inside the cleaning seat. When the cleaning plate moves into the cleaning seat, the brushes automatically remove the dust attached to the cleaning plate. When the gear fixed on the rotating rod meshes with the rack installed on the sliding bracket, the rack moves vertically and drives several brushes to deflect simultaneously, improving the cleaning quality and efficiency of the cleaning plate.

[0021] Several arc-shaped contact blocks fixed on the mounting strip can move synchronously with the electric push rod piston rod, which can achieve the purpose of intermittent contact with the second contact strip, so that the rack reciprocates and the brush blades continuously clean the cleaning plate automatically.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1, please refer to Figures 1 to 9 An adjustable-angle TV wall mount includes a base 1, a rotating arm 2 rotatably connected to the base 1, a mounting frame 3 rotatably connected to the other end of the rotating arm 2, a sliding groove 4 on the mounting frame 3, a movable strip plate 5 inside the sliding groove 4, a mounting arm 6 on one side of the mounting frame 3, a roller 7 rotatably connected to the mounting arm 6, and a positioning wedge 8 below the mounting frame 3.

[0034] The mounting frame 3 is equipped with a movable heat sink 9, and a silicone heat-conducting sheet 10 is fixed on the back of the heat sink 9. A guide slide 11 is fixed on the mounting frame 3, and a first guide rod 12 is slidably connected to the guide slide 11. A cleaning plate 13 is fixed to one end of the first guide rod 12.

[0035] A positioning plug 14 is fixed below the mounting arm 6, a first mounting block 15 is fixed on the mounting frame 3, and a second guide rod 16 is fixed at the lower end of the positioning wedge 8. The second guide rod 16 is elastically connected to the first mounting block 15 through a first spring 17.

[0036] A second spring 18 is connected between the strip plate 5 and the mounting frame 3, and a first abutment strip 19 is fixed at the lower end of the strip plate 5. A limit stop 20 is fixed on the strip plate 5, and a locking knob 21 is threadedly connected to one side of the mounting arm 6.

[0037] refer to Figures 1 to 4 When in use, first fix the base 1 in the concave TV background wall, and then connect the two mounting arms 6 to the back of the TV with screws. In order to facilitate the TV installation process, leave enough space and reduce obstruction. By pulling the mounting frame 3 to the side away from the wall, the rotating arm 2 can rotate between the mounting frame 3 and the base 1, so that the angle and position of the mounting frame 3 can be flexibly adjusted. Raise the two sides of the TV to align the rollers 7 on the mounting arm 6 with the strip plate 5, and then move them down so that the rollers 7 move down and abut against the strip plate 5, so that the rollers 7 are engaged in the sliding groove 4 on the mounting frame 3. The sliding groove 4 can restrict the movement direction of the rollers 7, so that the rollers 7 can only drive the mounting arm 6 to move horizontally. To improve the stability of the TV installation, the TV and the mounting frame 3 should be kept in the center. Then the TV can be pushed so that the rollers 7 can move horizontally in the sliding groove 4.

[0038] The position of the roller 7 is restricted after the limiting block 20 on the strip plate 5 keeps the TV in a centered position on the mounting frame 3. At the same time, the positioning plug 14 fixed on the mounting arm 6 moves synchronously. During the movement, the positioning plug 14 abuts against the positioning wedge 8 on the mounting frame 3. The positioning wedge 8 is forced to drive the second guide rod 16 to slide on the first mounting block 15. The first spring 17 stores force. When the positioning wedge 8 and the slot of the positioning plug 14 are aligned, the first spring 17 releases its elastic force, causing the positioning wedge 8 to automatically insert into the positioning plug 14 for locking and fixing, thus restricting the horizontal movement of the mounting arm 6. After the mounting arm 6 is installed in place, the locking knob 21 is manually rotated to lock the mounting arm 6 onto the mounting frame 3, realizing the child lock function to prevent children from accidentally touching it and to prevent the TV from falling off the mounting frame 3. During the TV installation process, fewer screws can be used to achieve the purpose of quick TV installation, which can improve the efficiency of disassembly and assembly.

[0039] Example 2 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1 to 9 A second mounting block 22 is fixed on the mounting frame 3. A hollow rod 23 is slidably connected to the second mounting block 22. A third spring 24 is connected between the hollow rod 23 and the second mounting block 22. A first abutting wedge 25 is fixed on the hollow rod 23. A third guide rod 26 is fixed on the heat sink 9. The third guide rod 26 is elastically connected to the hollow rod 23 through a fourth spring 27.

[0040] The other end of the first guide rod 12 is slidably connected to a sliding piece 28. A fifth spring 29 is connected between the sliding piece 28 and the first guide rod 12. A guide block 30 is fixed on the sliding piece 28. One end of the guide block 30 is inserted into the guide slide 11.

[0041] A rectangular block 31 is fitted onto the first guide rod 12, and an electric push rod 32 is fixed on the mounting frame 3. The piston rod of the electric push rod 32 is fixedly connected to the rectangular block 31.

[0042] A first clamping strip 33 is fixed on the cleaning plate 13. A second clamping strip 34 is provided on one side of the first clamping strip 33. An abutment rod 35 and a fourth guide rod 36 are fixed on the second clamping strip 34 respectively. The fourth guide rod 36 is slidably connected to the first clamping strip 33. The abutment rod 35 is elastically connected to the cleaning plate 13 through a sixth spring 351. A release film 37 is provided on the back of the silicone heat-conducting sheet 10. One side of the release film 37 is clamped between the first clamping strip 33 and the second clamping strip 34.

[0043] refer to Figures 1 to 8 When the strip plate 5 is pressed down, it causes the first abutting strip 19 to abut against the first abutting wedge 25. After the first abutting wedge 25 is abutted, it causes the hollow rod 23 to move horizontally on the second mounting block 22. The third spring 24 stores force, causing the heat sink 9, the silicone heat-conducting sheet 10 and the cleaning plate 13 to move horizontally synchronously. This causes the cleaning plate 13 to automatically abut against the back of the TV and make close contact with it. The cleaning plate 13 is made of sponge cleaning block, which has good elasticity, so that the cleaning surface of the cleaning plate 13 has a good fit with the back of the TV. When the cleaning plate 13 can no longer move after it is attached to the back of the TV, the third guide rod 26 slides in the hollow rod 23, and the fourth spring 27 stores force.

[0044] One side of the release film 37 is sandwiched between the first clip 33 and the second clip 34 on the cleaning plate 13. In the initial state, the back of the cleaning plate 13 is in close contact with the surface of the release film 37 on the silicone heat-conducting sheet 10. The fifth spring 29 connected between the sliding piece 28 and the first guide rod 12 is in a preliminary storage state to prevent the cleaning plate 13 from moving horizontally when it is not working, thus tearing off the release film 37 on the silicone heat-conducting sheet 10 and preventing dust from adhering to the silicone heat-conducting sheet 10 and affecting the adhesion effect. When the cleaning plate 13 is pressed against the back of the TV, the first guide rod 12 slides on the sliding piece 28 and the rectangular block 31, and the fifth spring 29 continues to store force.

[0045] When the piston rod of the electric push rod 32 extends, it drives the first guide rod 12 to move horizontally on the guide slide 11 via the rectangular block 31, so that the cleaning plate 13 performs local cleaning on the back of the TV, wiping away the dust and removing the release film 37 at the same time. This avoids the release film 37 being removed in advance and coming into contact with dust in the air, which would affect the subsequent bonding effect. If the release film 37 is removed after cleaning, it will be tightly attached to the back of the TV, resulting in greater resistance during removal and affecting the removal effect. The cleaning plate 13 removes the release film 37 while cleaning the TV background. When the cleaning plate 13 separates from the silicone heat-conducting sheet 10, the fifth spring 29 releases its elastic force. On one hand, the cleaning plate 13 moves closer to the mounting frame 3, and the contact rod 35 contacts the mounting frame 3, causing the first clamping strip 33 to separate from the second clamping strip 34. At this point, a portion of the release film 37 is still attached to the silicone heat-conducting sheet 10. After one side of the release film 37 is released from its clamping state, it can be easily removed manually. On the other hand, the cleaning plate 13 releases its restriction on the heat sink 9, allowing the fourth spring 27 to release its elasticity and automatically drive the heat sink 9 to move horizontally. This allows the surface of the silicone heat-conducting sheet 10 to adhere to the cleaned back of the TV. For TVs installed inside a background wall where ventilation is limited, internal heat dissipation is slow during operation, which can easily cause internal components to age over time and affect their service life. By attaching the silicone heat-conducting sheet 10 to the back of the TV, the internal heat of the TV can be dissipated to quickly reduce its internal temperature. The heat sink 9 can dissipate the heat in the silicone heat-conducting sheet 10 into the air, which can increase the heat dissipation area, reduce the risk of local high temperature, and improve the stability of TV operation.

[0046] The sliding piece 28 slidably connected to the first guide rod 12 is used to limit the position of the fifth spring 29, so that the fifth spring 29 can move synchronously with the first guide rod 12. The guide block 30 on the sliding piece 28 is connected to the guide slide 11, which can limit the movement angle of the sliding piece 28 and improve its movement stability. In order to reduce the friction between the sliding piece 28 and the guide slide 11 during the movement, several rotatable balls can be set on the sliding piece 28. After the balls contact the surface of the guide slide 11, the friction force on the sliding piece 28 during the movement can be reduced.

[0047] The cleaning plate 13 is provided with several protrusions, which can clean the gaps between the heat dissipation fins on the surface of the heat dissipation plate 9, thereby improving the cleaning effect of the heat dissipation plate 9.

[0048] Example 3 is an improvement upon Example 2. For details, please refer to [link / reference]. Figures 1 to 9 A cleaning seat 38 is fixed on one side of the mounting frame 3. Two rotating shafts 41 are rotatably connected to the cleaning seat 38. A first baffle 39 and a second baffle 40 are rotatably connected to the two rotating shafts 41 respectively. A torsion spring 42 is connected between the two rotating shafts 41 and the cleaning seat 38. A strip groove 52 is opened at the lower end of the cleaning seat 38.

[0049] The cleaning seat 38 is provided with several brush blades 43, a rotating rod 44 is fixed on the brush blades 43, a gear 45 is fixed on the rotating rod 44, the gear 45 is meshed with a rack 46, and a sliding bracket 47 is fixed on the cleaning seat 38. The sliding bracket 47 is elastically connected to the rack 46 through a seventh spring 48.

[0050] A second abutment strip 49 is fixed to one side of the rack 46, and an installation strip 50 is fixed to the rectangular block 31. Several arc-shaped abutment blocks 51 are fixed to the installation strip 50.

[0051] refer to Figures 1 to 9 After the silicone heat-conducting sheet 10 is attached to the back of the TV, the cleaning plate 13 is located on one side of the heat sink 9. When the piston rod of the electric push rod 32 is manually retracted or extended, the cleaning plate 13 can be driven to clean the dust on the surface of the heat sink 9 to improve the heat dissipation effect. When the cleaning plate 13 needs to be cleaned after cleaning the dust, the piston rod of the electric push rod 32 drives the cleaning plate 13 to approach the cleaning seat 38, causing the cleaning plate 13 to push the first baffle 39 and the second baffle 40 to deflect, so that the rotating shaft 41 rotates on the cleaning seat 38. The torsion spring 42 stores force, and after the cleaning plate 13 enters the cleaning seat 38, the first baffle 39 and the second baffle 40 automatically reset. To reduce dust accumulation inside the cleaning seat 38, the first guide rod 12 slides in the strip groove 52 at the lower end of the cleaning seat 38. At the same time, the rectangular block 31 drives the mounting strip 50 to move horizontally, which can achieve the purpose of intermittent contact between the several arc-shaped contact blocks 51 on the mounting strip 50 and the second contact strip 49. This causes the rack 46 to reciprocate on the sliding bracket 47 of the cleaning seat 38, thereby driving several gears 45 to rotate synchronously. The rotating rod 44 connected to the gears 45 drives the brush 43 to swing back and forth inside the cleaning seat 38, which can automatically clean the dust attached to the surface of the cleaning plate 13, thereby improving the quality of the next cleaning of the heat sink 9 by the cleaning plate 13.

[0053] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
