Description

Technical Field

[0001] This utility model relates to the field of LCD TV testing technology, and in particular to an LCD TV stand testing device. Background Technology

[0002] LCD TV stands are essential components that support LCD TVs, ensuring they are placed stably on a table or floor and preventing them from tipping over or sliding. LCD TV stands are typically made of materials such as metal or plastic, and their structures and shapes vary to accommodate different models and sizes of LCD TVs. Their design and stability are crucial for the safety of the TV and the user experience.

[0003] Chinese utility model patent CN221745505U discloses a device for detecting the stability of an LCD TV stand. The device involves placing the stand above and in front of a transport mechanism. Once the stand reaches the fixing mechanism, transport stops. A linear module 4 is activated, causing two L-shaped clamps 11 to move to the right and outside the stand. A linear motor 9 is then activated to retract, causing the L-shaped clamps 11 to move relative to each other around the hinge of the movable seat 10, thus fixing the stand in place. Finally, a force-applying mechanism is activated to contact the test plate 7. A button-type pressure sensor 13 is fixedly installed at the output end of the detection hydraulic rod 12. A reset cylinder 8 pushes the test plate 7 vertically, causing it to fit against the test plate 7. When the test plate 7 causes the stand to rotate to the left around the axis 6, it can be determined that the stand's stability is poor.

[0004] In the LCD TV stand testing device, the test plate rotates around the pivot, while the button-type pressure sensor is pushed linearly. When the test plate rotates to a certain extent, the orientation of the button-type pressure sensor can no longer keep in contact with the test plate, resulting in inaccurate test results.

[0005] Therefore, it is necessary to provide a new LCD TV stand detection device to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a device for detecting the stand of an LCD TV.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figure 1 , Figure 2 as well as Figure 3 , Figure 1 A schematic diagram of the overall structure of the LCD TV stand detection device provided by this utility model; Figure 2 A schematic diagram of the state structure of the LCD TV stand detection device provided by this utility model; Figure 3 A schematic diagram of the pressure sensor provided by this utility model.

[0022] In the specific implementation process, such as Figures 1 to 3 As shown, the LCD TV stand testing device provided by this utility model includes a base 1 and a pressure sensor 9. A support frame 2 is fixedly installed on the top of the base 1 to support the entire testing device. A support frame 2 is fixedly connected to the inner top of the support frame 2. A testing hydraulic rod 3 is fixedly connected to the inner side wall of the support frame 2. The testing hydraulic rod 3 is used to apply a testing force to the test plate 11. A mounting plate 4 is fixedly connected to the output end of the testing hydraulic rod 3. A mounting plate 5 is detachably connected to the end of the mounting plate 4 away from the testing hydraulic rod 3. Threaded holes for bolt connection are respectively opened on the mounting plate 4 and the mounting plate 5. A rotating seat 6 is fixedly connected to the mounting plate 5. Connecting seats 8 are rotatably connected to both ends of the rotating seat 6. Connecting rods 7 are fixedly connected to both ends of the rotating seat 6. Connecting holes are opened on the connecting seats 8. Connecting rods 7 are rotatably connected to the inner wall of the connecting holes. The ends of the two connecting seats 8 away from the rotating seat 6 are fixedly connected to the pressure sensor 9. The connecting seats 8 are fixedly connected to the pressure sensor 9 to ensure that the pressure sensor 9 can adjust its angle with the movement of the test plate 11.

[0023] A linear module 10 is fixedly connected to the top of the support frame 2. A U-shaped seat is fixedly installed at the output end of the linear module 10. Rotary shafts are rotatably installed on both the front and rear sides of the inner wall of the U-shaped seat. A test plate 11 is fixedly installed between the rotating shafts. A torsion spring 12 is provided on the outer wall of the rotating shaft. The two ends of the torsion spring 12 are fixedly connected to the side wall of the U-shaped seat and the test plate 11, respectively. A linear motor 13 with one end penetrating through and extending to the left side of the test plate 11 is fixedly installed on the right side of the test plate 11. Two L-shaped clamps 14 are hinged to the output end of the linear motor 13.

[0024] The linear motor 13 and the L-shaped clamp 14 work together to achieve precise fixation of the tripod and ensure the stability of the testing process. The hydraulic rod 3 and the pressure sensor 9 work together to achieve precise force application and testing of the tripod and ensure the accuracy of the test results.

[0025] The working principle of this utility model is as follows: In specific implementation, by activating the linear module 10, the U-shaped seat moves the test plate 11 and L-shaped clamp 14 to the right side outside the stand. The linear motor 13 is activated, causing the L-shaped clamp 14 to move relative to the hinge point of the movable seat, thus fixing the stand to the two L-shaped clamps 14. The detection hydraulic rod 3 is activated, pushing the mounting plate 1 4 and mounting plate 2 5, causing the pressure sensor 9 to move towards the test plate 11. After the pressure sensor 9 contacts the test plate 11, the test plate 11 drives the stand to rotate. The shaft rotates to the left, and the pressure sensor 9 rotates around the connecting rod 7 of the rotating seat 6, based on the pushing force of the detection hydraulic rod 3. This causes the pressure sensor 9 to come into contact with the surface of the test plate 11. The pressure sensor 9 detects the stability of the tripod. If the tripod is unstable, the value displayed by the pressure sensor 9 will be different, and the value will be transmitted to the external central control device. After the test is completed, the detection hydraulic rod 3 is reset, the pressure sensor 9 is separated from the test plate 11, and the torsion spring 12 provides the reset force, causing the test plate 11 to drive the tripod to return to the right around the shaft.
