Embodiment Construction

[0029] In order to make the technical problems to be solved, features and advantages of the present invention more obvious and understandable, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] The invention provides a measuring tool, figure 2 is a three-view view of an embodiment of the present invention ( figure 2 Middle I is the main view, II is the left view, and III is the top view). The measuring tool includes: a tightening screw 1, a body 2, a pressure block 3, a feeler gauge 4, and a rectangular hole 5 is opened on the body 2. Specifically:

[0031] (1) Feeler gauge:

[0032] Feeler gauge 4 belongs to the prior art, is a kind of sheet-shaped gauge, measures the size of gap with its thickness. Its length, width, and thickness can have various values. The feeler gauge 4 can be a standard feeler gauge, or a non-standard feeler gauge processed by the user himself, as long as its thic...

Abstract

The invention discloses a measuring tool which comprises a filler gauge, a body, a first pressing part and a second pressing part, wherein the body is a cylinder; a blind hole is formed at one end of the body along an axis direction; a plane which is vertical to an axis of the body is arranged at the bottom of the blind hole; the second pressing part is arranged at the bottom of the blind hole; at least one rectangular hole which passes through the blind hole from the surface of the body is formed on the body; the filler gauge is inserted into the rectangular hole and is locked at the bottom of the blind hole by the first pressing part through the second pressing part; and preferably, the first pressing part is a tightening bolt, the second pressing part is a pressing block, a convex arc-shaped surface is arranged at one end of the pressing block facing to the bolt, and a plane is arranged at one end of the pressing block facing to the bottom of the blind hole. When the measuring tool provided by the invention is used for measuring a gap in an inner cavity, the problems of lower accuracy and efficiency caused by an operation of manually inserting the filler gauge into the inner cavity and the easily blocking problem of the filler gauge caused by inconvenient operation and the like are solved.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a measurement tool. Background technique [0002] In production and life, when it is necessary to measure various gaps, people generally use a thin sheet gauge such as a feeler gauge to measure, and judge the size of the gap by the thickness of the feeler gauge that can be inserted. However, in the prior art, the feeler gauge is small and thin and inconvenient to hold, especially when the gap between the surfaces is located in the inner cavity, it is often necessary to pinch the feeler gauge with the thumb and forefinger to probe into the hole for measurement. [0003] For example, there is a valve seat hole in the engine field (the hole where the engine cylinder head is equipped with the valve seat). When the valve seat (also in the shape of a hole) is pressed in, it is necessary to insert a feeler gauge into the valve seat hole to keep the feeler gauge level. , and then measure whet...
