Description

Technical Field

[0001] The utility model relates to the technical field of O-rings, in particular to a novel O-ring quick measuring tool. Background Art

[0002] As a rubber seal, O-ring plays an important sealing role in the operation of our equipment and is widely used in machine seals, oil seals, cylinders, etc. However, the diversity of O-ring sizes poses a huge challenge to the applicability of spare parts.

[0003] O-rings have different diameters and lengths depending on the location of use. Especially for equipment that is being disassembled for inspection for the first time, the size measurement of an O-ring is likely to affect the progress of the entire maintenance activity. At the same time, O-rings have extremely strong plastic deformation capabilities, which puts forward new requirements on the skills of personnel during the size measurement process and increases the risk of equipment maintenance caused by size measurement errors. Therefore, a new type of O-ring quick measurement tool is proposed to solve the above problems. Utility Model Content

[0004] The utility model provides a novel O-ring quick measuring tool, which solves the above technical problems.

[0005] In order to solve the above technical problems, the utility model provides a novel O-ring quick measuring tool, including a shell, a telescopic rod slidably connected to the inside of the shell, a positioning ring fixed to the surface of the shell, a moving ring fixed to the surface of the telescopic rod, and the moving ring and the positioning ring are correspondingly arranged.

[0006] Preferably, a large measuring ring is fixed to the side of the shell, and a small measuring ring and a middle measuring ring are fixed to the other end of the shell relative to the large measuring ring.

[0007] Preferably, the surfaces of the large measuring ring, the small measuring ring and the medium measuring ring are provided with corresponding size numerical markings.

[0008] Preferably, a stretching distance scale is provided on the surface of the telescopic rod.

[0009] Preferably, the moving ring and the positioning ring are provided with different sizes and the moving ring and the positioning ring are arranged in a ring shape on the surface of the telescopic rod.

[0010] Compared with the related art, the novel O-ring quick measuring tool provided by the utility model has the following beneficial effects:

[0011] The utility model can expand the O-ring by means of a movable telescopic rod cooperating with a shell, and the size of the O-ring can be obtained according to the diameter of the telescopic rod and the movable ring positioning ring; the small-sized O-ring can be directly put on the surface of the large measuring ring, the middle measuring ring and the small measuring ring to obtain the corresponding size data, thereby facilitating the measurement of the O-ring size.
