Description

Technical Field

[0001] The invention relates to the technical field of hand tools, in particular to a sampling tool suitable for sampling, testing and analysis of lubricating oil of an alternator. Background Art

[0002] Generator lubricating oil may be contaminated by solid particles during use. In order to avoid excessive contamination, sampling and testing of lubricating oil is an important monitoring method. At present, due to the lack of special sampling tools, metal rods or small wooden sticks are usually used to push the motor lubricating oil self-sealing device to make the lubricating oil flow out. The above operation method has the following disadvantages: first, the flow rate is uncontrollable, which can easily cause oil splashing; second, it is affected by human factors and will cause secondary contamination to the sampled lubricating oil. Summary of the invention

[0003] The present invention provides a generator lubricating oil detection sampling tool, which aims to complete the sampling of the generator lubricating oil through the cooperation of a drainage guide rod, a screw plug, a sealing ring and an operating handle, so as to avoid oil splashing and prevent secondary contamination of the sample.

[0004] In order to achieve the above object, the present invention adopts the following technical scheme: A generator lubricating oil detection sampling tool is provided with a drainage guide rod, a screw plug, a sealing ring and an operating handle; the drainage guide rod is a rigid rod, provided with a center hole penetrating along the axial direction, and a drainage notch connected to the center hole is provided at the front end of the drainage guide rod; the screw plug and the operating handle are both sleeved on the outside of the drainage guide rod in an interference fit manner, wherein the screw plug is located at one end close to the guide notch, the size and thread structure of the screw plug are consistent with the size and thread structure of the lubricating oil seal of the generator, and the outer contour size of the operating handle is larger than the outer diameter size of the screw plug; the sealing ring is sleeved on the outside of the drainage guide rod and is located between the screw plug and the front end of the operating handle.

[0005] In the generator lubricating oil detection sampling tool, the guide notch of the guide rod is a rectangular notch.

[0006] The generator lubricating oil detection sampling tool has a rear end of the drainage guide rod extending through the rear end of the operating handle, and the drainage guide rod is a round tube made of stainless steel.

[0007] The above generator lubricating oil detection sampling tool, the operating handle is a cylindrical structure, and an anti-slip texture is provided on its outer surface.

[0008] The present invention provides a generator lubricating oil detection sampling tool, which can be screwed into the lubricating oil plug seat of the generator through a screw plug, and the front end of the guide rod pushes the spring in the generator lubricating oil self-sealing device, so that the lubricating oil in the generator enters the center hole of the guide rod through the guide notch of the guide rod, and under the action of the internal pressure of the generator, the lubricating oil flows out along the center hole of the guide rod. It can be seen that the present invention can smoothly guide the lubricating oil inside the generator through the cooperation of the guide rod, the screw plug, the sealing ring and the operating handle, thereby achieving the purpose of avoiding oil splashing and preventing secondary contamination of the sample.
