Description

Technical Field

[0001] This utility model relates to the field of television testing technology, and in particular to a fixing device for television testing. Background Technology

[0002] In the television production process, television testing is a crucial step, requiring the use of fixing devices to secure the televisions. However, existing television testing fixing devices have several shortcomings. Firstly, most existing fixing devices have relatively simple structures and lack flexibility in securing the television. For example, many devices can only fix the television in one direction, making it difficult to adjust flexibly for different sizes and models. This necessitates frequent device replacements or complex adjustments when testing different televisions, significantly reducing testing efficiency. Secondly, existing fixing devices have significant limitations in adjusting the television's position. When testing televisions, inspectors often need to observe and operate them from different angles and heights. However, existing fixing devices struggle to easily and quickly adjust the television to the appropriate position. Inspectors may need to manually move the television or use other auxiliary tools to achieve this, increasing their workload and increasing the risk of damage to the television due to manual handling, thus affecting the accuracy of the test results.

[0003] To better address the aforementioned issues, we propose a fixing device for television set testing. Utility Model Content

The lifting mechanism drives the lifting plate 8 to descend until the TV is located inside the third bracket 5. The second motor 9 drives the second bracket 7 to rotate, thereby adjusting the clamping plate 13 to be parallel to the edge of the TV. The telescopic mechanism 14 drives the clamping plate 13 to extend and retract, clamping the clamping plate 13 to the edge of the TV. After fixing, the lifting mechanism raises the TV and adjusts its height. The third motor 6 drives the third bracket 5 to rotate to flip the TV, and the second motor 9 drives the second bracket 7 to rotate the TV in the plane. This allows the TV to be adjusted to the required position for testing. The operation is very convenient and improves the efficiency of testing.

[0027] The operating principle of the lifting mechanism is as follows: the first motor 10 drives the first lead screw 11 to rotate, and the first lead screw 11 can drive the lifting plate 8 to rise and fall through the threaded transmission between it and the lifting plate 8. At this time, the lifting plate 8 slides and is guided on the first slide rod 12 to improve the stability of the lifting plate 8.

[0028] The operating principle of the telescopic mechanism 14 is as follows: the fourth motor 141 drives the second lead screw 142 to rotate. The second lead screw 142 can drive the first slider 143 to slide through the threaded transmission between it and the first slider 143. The first slider 143 pushes the clamping plate 13 to move through the first connecting rod 146. At this time, the first connecting rod 146 and the second connecting rod 147 rotate relative to each other and push the second slider 144 to slide on the second sliding rod 145 to ensure the stability of the movement of the clamping plate 13.
