Description

Technical Field

[0001] The present invention relates to the technical field of television display screens, and particularly to a household 4K ultra-high-definition television display screen. Background Art

[0002] A television display screen belongs to a type of flat panel display. It is used for the screen display of televisions and computers. The advantages of this display screen are low power consumption, small size, and low radiation. The television display screen uses a liquid crystal solution in two pieces of polarizing material. When an electric current passes through this liquid, the liquid crystal will rearrange to achieve the purpose of imaging. The television display screen is a type of display used in digital clocks and many portable computers. Existing television display screens all have functions such as 4K ultra-high definition.

[0003] In this regard, the prior art patent publication number: CN211606654U discloses a dust-proof mechanism for a television display screen interface, which includes two support feet of the same size. Above the support feet is a display screen. On the rear side of the display screen is a rear cover. On the rear cover and on the side far from the display screen are a first protective cover and a second protective cover. The second protective cover is located outside the first protective cover. This dust-proof mechanism for the television display screen interface can effectively dust-proof the interface extending from one side of the rear cover through the settings of the first protective cover and the first protective cover, avoiding the interface being exposed outside and being easily attached with dust, which may affect the use, and is beneficial to extending the service life of the television display screen interface.

[0004] However, in actual use, after the dust-proof cover is opened and then the connector is inserted into the interface, the dust-proof cover will still be in an open state. When used for a long time, dust in the room will enter the inside of the connector and the interface through the gap at the lower end of the dust-proof cover. As a result, the overall dust-proof function of the interface only has a short-term effect. Also, when installing and disassembling an existing wall-mounted television display, the operator cannot observe the connecting parts in contact between the display screen and the wall. Therefore, the operator can only dock or disassemble the display screen and the connecting parts by manual feeling. The overall operation is rather cumbersome. If it is only fixed to a group of connecting parts during installation, the subsequent stability is poor, and the television display screen may fall and damage the display screen. Therefore, improving and perfecting the above problems has become an urgent problem to be solved at present. Summary of the Invention

[0005] The object of the present invention is to provide a household 4K ultra-high definition TV display screen, so as to solve the problem that the dust cover will still be in an open state in the above-mentioned background technology. When the usage time is relatively long, indoor dust will enter the inside of the connector and interface through the gap at the lower end of the dust cover. As a result, the overall dust-proof function of the interface only has a short-term effect. Moreover, when installing and disassembling the existing wall-mounted TV display, the operator cannot observe the connecting parts in contact between the display screen and the wall. Therefore, the operator can only dock or disassemble the display screen and the connecting parts by manual feeling. The overall operation is relatively cumbersome. If it is only fixed to a group of connecting parts during installation, the subsequent stability is poor, and the battery display screen will fall and damage the display screen.

Their principles and connection methods are all well-known prior arts to those skilled in the art, so they will not be elaborated here. It includes a display screen body 1. An installation rear cover 2 is installed on the front surface of the display screen body 1. An installation rear cover 2 is installed on the inner side wall of the installation rear cover 2. A rotating column 3 is inserted and installed on the inner wall of the display screen body 1. An installation plate 4 is installed on the outer surface of the rotating column 3. A through groove 6 is opened inside the installation plate 4. The through groove 6 is adapted to the interface body 5. An adaptation groove 7 is opened on the inner wall of the installation plate 4. The adaptation groove 7 is opened on the four sides of the inner wall of the installation plate 4. An upper clamping frame 8 and a lower clamping frame 9 are installed in sequence from top to bottom inside the adaptation groove 7. On one side of the surface of the display screen body 1, a first rotating installation frame 40 and a first installation frame 28 are installed in sequence from left to right. A rotating ring 29 is installed on the outer surface of the first installation frame 28. An installation frame 30 is fixedly connected to the front surface of the rotating ring 29. A connecting shaft 31 is installed inside the installation frame 30. A connecting ring 32 is arranged on the front surface of the connecting shaft 31. An installation screw 33 is fixedly connected to the front end of the connecting ring 32. A threaded cylinder 34 is arranged on the outer surface of the installation screw 33. One end of the threaded cylinder 34 away from the installation screw 33 is installed with a movable sleeve 35. A second installation frame 36 is arranged inside the movable sleeve 35. The second installation frame 36 is installed on a wall or a plate. A first bevel gear column 37 is fixedly connected to the back surface of the connecting shaft 31. A second bevel gear column 38 is meshed and connected to the outer surface of the first bevel gear column 37. The top surface of the second bevel gear column 38 penetrates through the top surface of the installation frame 30 and is installed with a crank handle body 39. A stabilizing plate 41 is installed on the outer surface of the first rotating installation frame 40. A plug rod 42 is installed inside the first rotating installation frame 40. A plug cylinder 43 is installed on the outer surface of the plug rod 42. A second rotating installation frame 44 is installed on the outer surface of the plug cylinder 43.

The plug cylinder 43 is adapted to the plug rod 42. The back surface of the threaded cylinder 34 abuts against the front surface of the connecting ring 32. The threaded cylinder 34 is adapted to the installation screw 33. When installing the display screen body 1 and the installation rear cover 2, first align the installation screw 33 with the threaded cylinder 34, then turn the crank handle body 39. Then the crank handle body 39 will drive the second bevel gear column 38 to rotate. Subsequently, the first bevel gear column 37 can be driven to rotate through the second bevel gear column 38. Then the first bevel gear column 37 will drive the connecting shaft 31 and the connecting ring 32 to rotate. Then the installation screw 33 can be driven to be threadedly installed inside the threaded cylinder 34. Thus, the installation screw 33 can be adaptively installed with the threaded cylinder 34. At the same time, when the installation screw 33 is aligned with the threaded cylinder 34, at this time, the two groups of plug rods 42 will also be inserted and installed into the plug cylinder 43. Thus, the overall installation effect is good and there is no need to install by human feeling.When the installation screw rod 33 enters the inside of the threaded cylinder 34, the insertion rod 42 will also be stably inserted into the inside of the insertion cylinder 43, and the overall insertion effect is good. Therefore, the installation can be completed quickly. At the same time, when disassembling later, at this time, the first installation frame 28 and the rotating ring 29 are movably installed, and at the same time, the movable sleeve 35 and the threaded cylinder 34 can rotate. Similarly, the first rotating installation frame 40 and the stabilizing plate 41, and the insertion cylinder 43 and the second rotating installation frame 44 can all rotate. Then, the display body 1 is operated to be in an inclined state. At this time, continue to manually rotate the handle body 39 in the reverse direction, and the installation screw rod 33 can be slowly separated from the inside of the threaded cylinder 34, and the installation screw rod 33 and the threaded cylinder 34 can be quickly separated, so as to facilitate the quick disassembly of the display body 1 and the installation rear cover 2 from the wall or the plate, and the overall disassembly effect is good. This setting can accurately dock the installation parts during installation, and after the installation is completed, the positions of the display body 1 and the installation rear cover 2 can be adjusted to an inclined state for use. Moreover, after the display body 1 and the installation rear cover 2 are in an inclined state, it is also convenient for subsequent disassembly of the display body 1 and the installation rear cover 2. Therefore, the problem that the connecting parts cannot be intuitively viewed when installing and disassembling the display body 1 and the installation rear cover 2 in the past is solved, and the efficiency of installing and disassembling the display body 1 and the installation rear cover 2 becomes faster; The upper side blocks 10 are installed on the left and right sides of the upper clamping frame 8. The lower side blocks 11 are installed on both left sides of the lower clamping frame 9. An iron block 12 is installed at the lower end of the upper side block 10. A magnet 13 is fixedly connected to the top surface of the lower side block 11. The iron block 12 and the magnet 13 are magnetically attracted to each other. A first movable block 14 is installed on the right surface of the upper side block 10. A screw rod body 15 is inserted and installed inside the first movable block 14. A motor frame 16 is installed on the top surface of the screw rod body 15. The motor frame 16 is installed on the inner wall of the mounting plate 4. A second movable block 18 is fixedly connected to the right side of the lower side block 11. A limiting rod 17 is inserted and installed inside the second movable block 18. The second movable block 18 and the screw rod body 15 are mutually adapted. A transmission mechanism 19 is installed on the outer surface of the screw rod body 15. The transmission mechanism 19 penetrates through the front surface of the mounting plate 4 and is installed with a rotating shaft 20. The rotating shaft 20 is installed on the lower surface of the transmission mechanism 19. A rotating disk 21 is fixedly connected to the lower end of the rotating shaft 20. A connecting column 22 is arranged at the lower end of the rotating disk 21. A movable frame 23 is installed on the outer surface of the connecting column 22. A limiting frame 24 is arranged on the outer surface of the movable frame 23. There are two groups of limiting frames 24. The lower end of the limiting frame 24 is fixedly connected to a support block 25. The support block 25 is installed on the front surface of the mounting plate 4. The limiting frame 24 and the movable frame 23 are mutually adapted. A piston rod 26 is installed on the left side of the movable frame 23. An air delivery cylinder 27 is arranged on the outer surface of the piston rod 26. An airbag frame 45 is installed on the left side of the air delivery cylinder 27. The airbag frame 45 is installed on the front surface of the mounting plate 4. A fitting sealing pad 46 is installed on the inner side wall of the airbag frame 45. The fitting sealing pad 46 and the through groove 6 are mutually adapted. When the display body 1 and the mounting rear cover 2 are integrally installed on a wall or a board, at this time, the mounting plate 4 is installed into the inside of the mounting rear cover 2. At this time, the interface body 5 and the through groove 6 are mutually adapted. Then the connector is inserted into the inside of the interface body 5 through the through groove 6. When the connector is inserted, at this time, the drive motor on the surface of the motor frame 16 is started, and then the drive motor drives the screw rod body 15 to rotate. Subsequently, the first movable block 14 and the second movable block 18 on the surface of the screw rod body 15 will move relative to each other. At this time, the first movable block 14 drives the upper side block 10 and the upper clamping frame 8 downward, and the second movable block 18 drives the lower side block 11 and the lower clamping frame 9 upward. And the upper clamping frame 8, the lower clamping frame 9, the upper side block 10 and the lower side block 11 all move inside the fitting groove 7. Then when the upper side block 10 and the lower side block 11 are close to each other, at this time, the iron block 12 and the magnet 13 are magnetically attracted to each other, so that the movement of the overall upper clamping frame 8 and the lower clamping frame 9 ends. At the same time, the motor frame 16 stops moving. At this time, the upper clamping frame 8 and the lower clamping frame 9 are respectively installed on the upper and lower surfaces of the plug, and the two groups of upper side blocks 10 and lower side blocks 11 are respectively installed on the left and right surfaces of the plug. This setting can prevent indoor dust from entering the inside of the interface body 5. Thus, through the settings of the upper clamping frame 8, the lower clamping frame 9, the upper side block 10 and the lower side block 11, it can be isolated from the outside world, so as to perform dust prevention operation on the interface body 5 from the source.The overall dust-proof operation has a good effect. At the same time, through the settings of the upper clamping frame 8, the lower clamping frame 9, the upper side block 10 and the lower side block 11, the connector inserted and installed inside the interface body 5 can be limited and fixed, which can prevent the connector from falling off. At the same time, when the screw rod body 15 rotates, it will also drive the transmission mechanism 19 to rotate. Then, the transmission mechanism 19 will drive the rotating shaft 20 to rotate. Then, the rotating shaft 20 will drive the rotating disk 21 and the connecting column 22 to rotate. Then, the movable frame 23 will move reciprocally left and right. The movement of the movable frame 23 is limited by the limiting frame 24. Then, the movable frame 23 will drive the piston rod 26 to move reciprocally inside the air supply cylinder 27. The overall movement effect is good. Thus, through the reciprocating movement of the piston rod 26 inside the air supply cylinder 27, gas can be transported into the airbag frame 45, and then the airbag frame 45 can be inflated. At this time, after the airbag frame 45 is inflated, the fitting sealing pad 46 will fit on the outer surface of the connector, which can prevent indoor dust from entering the vicinity of the installation rear cover 2 and the interface body 5 through the through groove 6. Therefore, through the inflated airbag frame 45 and the fitting sealing pad 46 in this setting, the outer surface of the plug that has been inserted into the interface body 5 can be subjected to a fitting and sealing operation. At the same time, the plug inside the mounting plate 4 is sealed again through the upper clamping frame 8, the lower clamping frame 9, the upper side block 10 and the lower side block 11, which can achieve double dust-proof sealing and always prevent dust from entering the interface body 5, solving the problem that only the connector and the interface body 5 could be sealed briefly in the past. The structures of the piston rod 26 and the air supply cylinder 27 are the same as those of the air pump in the prior art and can inflate the airbag frame 45. And through the design of the support block 25, the two limiting frames 24 can be limited.,

[0022] Working principle: When the staff uses this device, first connect the device to an external power supply to provide power support for the device. When installing the display body 1 and the installation rear cover 2 as a whole on the wall or board, install the mounting plate 4 inside the installation rear cover 2 at this time. At this time, the interface body 5 and the through groove 6 are mutually adapted. Then insert the connector into the interface body 5 through the through groove 6. When the connector is inserted, start the drive motor on the surface of the motor frame 16 at this time. Then the drive motor will drive the lead screw body 15 to rotate. Subsequently, the first movable block 14 and the second movable block 18 on the surface of the lead screw body 15 will move relative to each other. At this time, the first movable block 14 drives the upper side block 10 and the upper clamping frame 8 downward, and the second movable block 18 drives the lower side block 11 and the lower clamping frame 9 upward. And the upper clamping frame 8, the lower clamping frame 9, the upper side block 10 and the lower side block 11 all move inside the fitting groove 7. Then when the upper side block 10 and the lower side block 11 approach, the iron block 12 and the magnet 13 are magnetically attracted to each other. Thus, the overall movement of the upper clamping frame 8 and the lower clamping frame 9 ends, and at the same time, the motor frame 16 stops moving. At this time, the upper clamping frame 8 and the lower clamping frame 9 are respectively installed on the upper and lower surfaces of the plug, and the two groups of upper side blocks 10 and lower side blocks 11 are respectively installed on the left and right surfaces of the plug. At the same time, through the settings of the upper clamping frame 8, the lower clamping frame 9, the upper side block 10 and the lower side block 11, the connector inserted and installed inside the interface body 5 can also be limited and fixed, which can prevent the connector from falling off. At the same time, when the lead screw body 15 rotates, it will also drive the transmission mechanism 19 to rotate. Then the transmission mechanism 19 will drive the rotating shaft 20 to rotate. Then the rotating shaft 20 will drive the rotating disc 21 and the connecting column 22 to rotate. Then the movable frame 23 will reciprocate left and right. The movement of the movable frame 23 is limited by the limiting frame 24. Then the movable frame 23 will drive the piston rod 26 to reciprocate inside the air delivery cylinder 27. The overall movement effect is good. Thus, through the reciprocating movement of the piston rod 26 inside the air delivery cylinder 27, gas can be delivered into the airbag frame 45, and then the airbag frame 45 can be inflated. At this time, after the airbag frame 45 is inflated, the fitting gasket 46 will fit on the outer surface of the connector, which can prevent indoor dust from entering the vicinity of the installation rear cover 2 and the interface body 5 through the through groove 6; When installing the display body 1 and the installation rear cover 2, first align the installation screw rod 33 with the threaded cylinder 34, then turn the handle body 39. Then the handle body 39 will drive the second bevel gear column 38 to rotate. Subsequently, the first bevel gear column 37 can be driven to rotate by the second bevel gear column 38. Then the first bevel gear column 37 will drive the connecting shaft 31 and the connecting ring 32 to rotate. Then the installation screw rod 33 can be threadedly installed inside the threaded cylinder 34, so that the installation screw rod 33 can be adaptively installed with the threaded cylinder 34. At the same time, when the installation screw rod 33 is aligned with the threaded cylinder 34, the two groups of insertion rods 42 will also be inserted into the insertion cylinder 43. Thus, the overall installation effect is good, and there is no need to install by human feeling. And when the installation screw rod 33 enters the threaded cylinder 34, the insertion rod 42 will also be stably inserted into the insertion cylinder 43. At the same time, when disassembling later, the first mounting bracket 28 and the rotating ring 29 are movably installed, and the movable sleeve 35 and the threaded cylinder 34 can rotate. Similarly, the first rotating mounting bracket 40 and the stabilizing plate 41, and the insertion cylinder 43 and the second rotating mounting bracket 44 can all rotate. Then operate the display body 1 to be in an inclined state. At this time, continue to manually rotate the handle body 39 in the reverse direction, and the installation screw rod 33 can be slowly disengaged from the threaded cylinder 34, and the installation screw rod 33 can be quickly disengaged from the threaded cylinder 34, so as to facilitate the quick disassembly of the display body 1 and the installation rear cover 2 from the wall or the plate. The above is all the working principles of the present invention.

[0023] The above is only the preferred embodiment of the present invention, and it is not intended to limit the present invention in any form; any ordinary technical personnel in the industry can smoothly implement the present invention according to the instructions in the drawings and the above description; however, any slight changes, modifications and evolutions made by those familiar with the technology within the scope of the technical solution of the present invention by using the technical content disclosed above are equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essence of the present invention still fall within the protection scope of the technical solution of the present invention.
