Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts, and relates to a marking auxiliary tool for seat belt fixing point strength test. Background Technique

[0002] In the test of automobile seat belt fixing points, a camera is used to record the test to obtain key information during the whole test process. When using the camera for recording, it is required to use two cameras at the same time. The two cameras are parallel to each other, the distance between the centers of the lenses is 100 mm, and the two cameras need to be kept horizontal, and the center line is perpendicular to the longitudinal center plane of the vehicle.

[0003] At present, bright and vivid cross markings are often used for reference. The horizontal marking needs to be parallel to the driving direction of the automobile, and the distance between the two vertical markings is 100 mm. This requires the use of a large frame to add the cross markings. However, when setting the reference markings in the past, since the frame was built and connected by aluminum profiles, it was very inconvenient to adjust the cross markings, and it was also inaccurate. It was necessary to loosen the cross markings first, use a spirit level to find the position required by the standard, and then adjust the cross markings. The top and bottom of the cross markings were connected by bolts, which belonged to the nature of set screws. When adjusting, the set screws were loosened and adjusted left and right, up and down respectively. It was difficult to ensure the levelness and perpendicularity of the adjustment, and the square frame built by aluminum profiles was unstable, making the reference markings set inaccurately and affecting the use value of the reference markings. Summary of the Utility Model

[0004] In view of the above technical problems and disadvantages, the purpose of the utility model is to provide a marking auxiliary tool for seat belt fixing point strength test. The marking auxiliary tool effectively solves the problems of marking verticality and horizontality, and can also realize simultaneous adjustment, ensuring the problems of marking horizontality, parallelism to each other and perpendicularity to each other.
