Description

Technical Field

[0001] This utility model is a marking device for salt spray resistance testing, belonging to the technical field of anti-corrosion coating marking equipment. Background Technology

[0002] According to the requirements of standards such as GB / T5237.4, GB / T5237.5, and GB / T1771, before the salt spray test, two lines need to be drawn on the surface of the sample to expose the substrate. The width of the lines has certain requirements, generally 0.3-1.0 mm. After the salt spray test, the salt spray resistance of the sample is evaluated based on the width of the single-sided penetration corrosion under the film on both sides of the drawn lines.

[0003] Chinese patent CN218847934U proposes a scribing device for salt spray resistance testing. The scribing device fixes the sample by clamping rods. Utilizing the lever principle, the pressure on the sample being clamped must be greater than the pressure applied by hand. However, due to the varying thicknesses of different samples, the clamping rods always rotate around a fixed point in this fixing method. This method cannot achieve a good fixing effect when dealing with thicker profiles, resulting in low practicality. There is an urgent need for a scribing device for salt spray resistance testing to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a scribing device for salt spray resistance testing, thereby solving the problems mentioned in the background section. This invention has a reasonable structure, and by adjusting the height of the moving seat, the height of the rotation center of the flipping pressure plate can be adjusted, thus adapting to clamping and fixing samples of different thicknesses. It is simple and convenient to use and highly practical.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a scribing device for salt spray resistance testing, comprising a base, an operating table, a limiting slide rod, a movable seat, an adjusting rod, a flipping pressure plate, a limiting slide groove, a sliding seat, and a scribing head. The operating table is mounted on the upper surface of the base. A limiting slide rod is provided on the right side of the operating table.

A scribing head is provided inside the sliding seat.

[0006] Furthermore, the sliding seat is provided with limit sliders on both sides, the limit sliders slide tightly along the inner wall of the limit groove, the sliding seat is slidably engaged with the limit groove through the limit sliders, the sliding seat is provided with a movable plate inside, and the scribing head is provided on the lower end face of the movable plate.

[0007] Furthermore, a reset spring is provided inside the sliding seat, and the two ends of the reset spring abut against the upper surface of the moving plate and the inner wall of the sliding seat, respectively. A connecting handle is installed on the upper surface of the moving plate, and four sets of the limiting slide groove, the sliding seat and the scribing head are provided with equal specifications.

[0008] Furthermore, the movable seat is provided with connecting shafts on both the front and rear sides, and the right end face of the flipping pressure plate is provided with a rotating connector. The flipping pressure plate is rotatably connected to the connecting shaft through the rotating connector. The end of the flipping pressure plate that is relatively away from the rotating connector is provided with a flipping handle, and the lower end face of the flipping pressure plate is glued with an anti-slip pad.

[0010] Furthermore, the lower end face of the base is equipped with a foot, and two sets of the limiting slide rods are provided. The upper end face of the movable seat is provided with a through hole, and the limiting slide rod passes through the through hole and through the movable seat.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a scribing device for salt spray resistance testing. Because this utility model adds a base, adjusting rod, threaded groove, threaded seat, and movable seat, when changing samples of different thicknesses, the user first flips the base and drives the adjusting rod to rotate using the corresponding hexagonal adjusting tool. Since the threaded groove of the adjusting rod and the threaded seat mesh with each other, the height of the movable seat can be adjusted, thereby changing the rotation center of the flipping pressure plate until the flipping pressure plate is kept horizontal and its lower end face is parallel to the upper end face of the sample. At this time, it can ensure that the flipping pressure plate has a good and stable pressing and fixing effect on the sample. Attached Figure Description
