Description

Technical Field

[0001] The utility model relates to the technical field of automobile safety detection, in particular to a non-disassembly flaw detector fixing device. Background Art

[0002] The non-disassembly flaw detector uses the eddy current flaw detection principle. According to the rough and uneven surface of automobile metal parts, it can directly perform non-destructive testing on the surface of vulnerable parts without disassembling automobile metal parts.

[0003] A flaw detector is often used to detect flaws in different locations and components. Usually, the position of the flaw detector should be arranged according to the height and shape of the part to be inspected. At the same time, the flaw detector should be fixed to avoid damage to the flaw detector due to bumps, drops, etc.

[0004] The existing flaw detector fixing device can only be adjusted in the horizontal and vertical directions within a small range limited by the fixing bracket. The movement of the entire bracket is not convenient, and the installation is not convenient either.

[0005] For example, a lifting flaw detector fixture disclosed in Chinese patent CN210241082U is provided with a rotating handle on the upper part of the lifting column, which makes the lifting operation of the entire fixture very convenient and easy to use. An anti-sway plate structure is added to minimize deflection of the threaded screw when it is lifted up and down, thereby extending the service life of the screw.

[0006] However, after the device fixes the non-disassembly flaw detector, when the angle of the non-disassembly flaw detector needs to be adjusted, the entire fixing device needs to be moved to adjust the angle of the non-disassembly flaw detector, which is inconvenient to use.

[0007] For this reason, we urgently need to provide a non-disassembly flaw detector fixing device. Utility Model Content
