Abstract
The utility model relates to a measuring tool and discloses a circular hole diameter and depth measuring tool comprising a measuring cylinder and a handle, wherein the handle is fixedly connected with the measuring cylinder which is formed by nesting a plurality of hollow round cylinders, the hollow round cylinders are equal in length and extensile length, and a graduation line is carved on the outer wall of each hollow round cylinder. The circular hole diameter and depth measuring tool brought forward in the utility model is characterized by simple structure, convenience of operation, capability of measuring round holes of different sizes, and practicality.
Description
Technical field
The utility model relates to surveying instrument, has proposed a kind of diameter and depth measurement tools of circular hole.
Background technology
When the circular hole in some plant equipment is measured, need to measure the degree of depth and the diameter of circular hole, conventionally can not settle at one go and will measure these two numerical value, separately measure.In the time measuring diameter, the method for using is generally the ruler direct method of measurement, and artificial like this error is very large, while fathoming, the method of using is generally and uses elongated rod method of substitution, and elongated rod is inserted to circular hole, thereby then measures the degree of depth of elongated rod in circular hole and calculate the degree of depth of circular hole.
Utility model content
For the problems referred to above, the utility model proposes a kind of diameter and depth measurement tools of circular hole.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The diameter of circular hole and a depth measurement tools, comprise handle, is connected with measuring cylinder on handle, and the measuring cylinder of stating is the nested compositions of multiple hollow cylinders, the identical length of described hollow cylinder etc., and exsertile length also equates.
Further, the table mural painting of described hollow cylinder has scale mark.
Further, the wall thickness of described hollow cylinder all equates.
Compared with prior art, the beneficial effects of the utility model are: nested by multiple hollow cylinders, in the time measuring the circular hole degree of depth and diameter, only measuring cylinder need to be pushed to circular hole, until after cannot pushing, scale on diameter and the hollow cylinder of the maximum hollow cylinder that observation is stretched out can be known diameter and the degree of depth of circular hole, simple to operate.
Brief description of the drawings
Fig. 1 is structural drawing of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
As shown in Figure 1, a kind of diameter of circular hole and depth measurement tools, comprise handle 1, is connected with measuring cylinder 2 on handle 1, and the measuring cylinder 2 of stating is the nested compositions of multiple hollow cylinders, the identical length of described hollow cylinder etc., and exsertile length also equates.
The table mural painting of described hollow cylinder has scale mark, and the wall thickness of described hollow cylinder all equates.
When concrete use, only measuring cylinder need to be pushed to circular hole, until after cannot pushing, scale on diameter and the hollow cylinder of the maximum hollow cylinder that observation is stretched out can be known diameter and the degree of depth of circular hole, hollow cylinder has identical thickness, measuring when Circularhole diameter, only need to understand the diameter that stretches out number and just can know circular hole of cylinder.
Claims (3)
1. the diameter of a circular hole and depth measurement tools, comprise handle (1), it is characterized in that: on handle, be connected with measuring cylinder (2), described measuring cylinder is the nested compositions of multiple hollow cylinders, the identical length of described hollow cylinder etc., exsertile length also equates.
2. the diameter of a kind of circular hole according to claim 1 and depth measurement tools, is characterized in that: the table mural painting of described hollow cylinder has scale mark.
3. the diameter of a kind of circular hole according to claim 1 and depth measurement tools, is characterized in that: the wall thickness of described hollow cylinder all equates.
