Description

Technical Field

[0001] This utility model relates to the field of LCD TV technology, specifically to an LCD TV with a wall mount. Background Technology

[0002] The rapid development of LCD technology has increased the popularity of LCD TVs, leading to their rapid rise in popularity and prompting the upgrading of LCD TV accessories. In order to ensure the installation and fixation of LCD TVs, LCD TVs are now gradually starting to come with wall mounts.

[0003] However, existing LCD TVs with wall mounts still have the following technical problems when in use:

[0004] Existing wall mounts lack protective measures for the TV after installation and fixation. When the TV is not in use, the screen is easily touched and accumulates fingerprints or dust, both of which affect the viewing experience of the LCD TV.

[0005] Therefore, a liquid crystal television with a wall mount is proposed to solve the aforementioned problems. Utility Model Content

[0025] Example:

[0026] Please see Figure 1-6 This utility model provides a technical solution:

[0027] A liquid crystal television with a wall mount includes a protective frame 1. The side wall of the protective frame 1 has a storage cavity. A first cylinder 2 is fixed to the rear end of the inner wall of the storage cavity. A U-shaped plate 3 is fixed to the front end of the first cylinder 2. A rotating block 4 is rotatably arranged inside the U-shaped plate 3 via a pivot pin. A clamping mechanism is fixed to the front end of the upper and lower sides of the rotating block 4. A display screen 22 is fixed between the two clamping mechanisms. An angle adjustment mechanism is provided between the left and right sides of the U-shaped plate 3 and the rotating block 4. Symmetrical mounting brackets 5 are fixed to the upper and lower sides of the protective frame 1.

[0028] A lifting plate 6 is horizontally arranged at the lower end of the storage cavity. A protective curtain 7 is fixed to the lower side of the lifting plate 6. The lower end of the protective curtain 7 is fixedly connected to the lower end of the inner wall of the storage cavity. A transmission mechanism is fixed to the left side of the lifting plate 6, and a limit mechanism is fixed to the right side of the lifting plate 6. The protective curtain 7 can be tightly stretched and protected at the front end of the display screen 22 under the action of the lifting plate 6, effectively protecting the display screen 22.

[0029] The clamping mechanism includes a first telescopic plate 8. The two first telescopic plates 8 are fixedly connected to the side wall of the rotating block 4 on their adjacent sides. A second telescopic plate 9 is slidably arranged inside the two first telescopic plates 8. A clamping plate 10 is fixed to the other side of the two second telescopic plates 9. Rubber shock-absorbing pads are fixed to the side walls of the two clamping plates 10. Fastening bolts are fixed to the left side of the two first telescopic plates 8. The right ends of the two fastening bolts are engaged with the left side of the second telescopic plate 9, which facilitates clamping and fixing the display screen 22. The position of the two clamping plates 10 can be adjusted to fix display screens 22 of different sizes.

[0030] The angle adjustment mechanism includes a first U-shaped block 11, which is fixedly connected to the side wall of the U-shaped plate 3. A second U-shaped block 12 is fixed to the side wall of the rotating block 4. The first U-shaped block 11 and the second U-shaped block 12 both have mounting blocks 13 that rotate through shaft pins. A second cylinder 14 is fixed between the two mounting blocks 13. When the angle adjustment mechanism is working, if the angle of the rotating block 4 is to be changed, one second cylinder 14 needs to extend and the other second cylinder 14 needs to shorten, thereby changing the angle of the rotating block 4.

[0031] The transmission mechanism includes a motor 15, which is fixedly connected to the left end of the inner wall of the storage cavity. A lead screw 16 is fixed to the output end of the motor 15. The upper end of the lead screw 16 is rotatably connected to the inner wall of the storage cavity through a bearing. A lifting block 17 is threaded on the rod wall of the lead screw 16. The right side of the lifting block 17 is fixedly connected to the left side of the lifting plate 6. The motor 15 is a forward and reverse motor. The motor 15 drives the lead screw 16 to rotate, and the lead screw 16 drives the lifting block 17 threaded on the rod wall to move. The lifting block 17 drives the lifting plate 6 on the side wall to move, thereby realizing the pulling of the protective curtain 7.

[0032] The limiting mechanism includes a limiting rod 18, which is longitudinally fixed to the right end inside the storage cavity. A limiting block 19 is slidably provided on the rod wall of the limiting rod 18, and the left side of the limiting block 19 is fixedly connected to the right side of the lifting plate 6.

[0033] The side wall of the lifting plate 6 is fixed with evenly arranged mounting tubes 20. A cooling fan 21 is fixed inside the mounting tube 20. The airflow direction of the cooling fan 21 is towards the front end of the display screen 22. It can not only dissipate heat when the display screen 22 is working, but also remove dust adsorbed by static electricity on the surface of the display screen 22.

[0034] Working principle:

[0035] When watching TV is needed, the first cylinder 2 is activated, which moves the display screen 22 at the front end to the front of the protective frame 1. The rotation angle of the display screen 22 can be adjusted by two angle adjustment mechanisms according to the needs of watching TV. When watching TV is not needed, the first cylinder 2 retracts, moving the display screen 22 into the interior of the protective frame 1. The motor 15 is activated, which drives the lead screw 16 at the output end to rotate. The lead screw 16 drives the lifting block 17 connected to the rod wall threaded upward. The lifting block 17 drives the lifting plate 6 on the side wall to move upward. The lifting plate 6 moves upward under the limiting action of the limiting rod 18 and the limiting block 19, thereby tightening the protective curtain 7 and protecting the front end of the display screen 22.
